UG Symposium Presentation Abstracts Aaron, Lostutter Faculty mentor: John Tester, College of Engineering, Forestry and Natural Sciences (CEFNS) Manufacturing Rocket Engine Nozzles with 3D Printing During the 2012-2013 academic year, an experiment is ongoing to examine the integration of 3D printing into the fabrication of Estes rocket engine nozzles. The rocket engines nozzles are manufactured using a ZPrinter 310 combined with a unique ceramic powder blend. This blend consists of 62.50% Redart TerraCotta, 31.25% MaltoDextrin, and 6.25% binder solution. Using ovens, the firing of nozzles is tested against various temperatures to acquire uniform shrinking. Nozzles deemed adequate are integrated back into C6-5 Estes rockets using a specially designed sleeve. Incorporating the sleeve into a manufactured test stand will allow for observation of fired rockets. Analysis of tested nozzles includes inspecting effects of erosion during rocket firing. Nozzle radii are measured before and after testing, providing satisfactory data for erosion analysis. Depending on test outcomes, further analysis will be performed to determine the effects of mass, sustained thrust, peak thrust, and duration. If successful, 3D printing could be implemented to optimize the design of rocket engine nozzles. Acosta, Celina Faculty mentor: George Gumerman, Honors Program Eating Disorders and the Media: An Analysis of how Women are Affected Over time, American culture has encouraged women to engage in or adapt eating disorders through how the media, T.V. shows, and advertisements portray how women should look. Eating disorders are a way for women to express their desire and need to feel and be thin. Any amount of fat on a woman’s body is seen as unattractive and unacceptable through society and the media’s eyes. Because of these strict standards, females have become insecure in themselves and have found extreme ways to attain the wanted body image that has taken over many young girls, teenage girls, and women’s mindsets. A way to cope with and achieve this image of the “perfect” body is through eating disorders such as bulimia, anorexia, and orthorexia. These are serious disorders that can harm individuals and through the media highlighting how women should appear they do not help the seriousness of these disorders. Through a poster presentation, I will exhibit the negative effects of media influence on women’s body image through bulimia, anorexia, and orthorexia.

Our team’s primary objective is to design the frame, fairing and steering of the vehicle. The frame and fairing must interface with the drivetrain that is being designed by another team. A new frame is designed and constructed to be lightweight by using honeycomb and aluminum tubing. Both of these materials were selected for their high strength and rigidity to weight ratio. Using finite element analysis and experimentation we were able to determine that the chosen design would hold the load needed with a minimum factor of safety of 3. The fairing is made out of fiberglass and is designed to be extremely aerodynamic. Using concepts from subsonic incompressible flow and aerodynamics, we created the smallest cross-sectional area possible, a rounded cone type shape front, and a narrowed back end. The car is made to be extremely safe, as it is driven in a competition where the safety of both the driver and other competitors are at risk. Adkins, Hailey Theresa Pol, Chelsea Olson Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) Does Organization of Handwriting Influence Perception of Academic Performance? Different handwriting styles were compared to see the effect it has on perceived academic performance. This study was conducted to determine the link between organization and perceived intelligence. Two different handwriting samples were used; an organized, neat sample and an unorganized, messy sample. Both were identical in content. The two samples were dispersed randomly to students in PSY 302W courses. Participants were asked to read the paragraph, and rate it on a scale of 1 to 10 with 10 being the highest and 1 the lowest. The researchers hypothesized that the participants would assign their ratings of academic performance based on their perceptions of the organization of the paragraph. As was predicted, the participants generally gave higher ratings to the neat paragraph, than to the messy one. However, this study only tested a small portion of college students; additional studies should be conducted to compare results possibly focusing on the age and gender of the participants. Aflitto, Nicholas Richard Hofstetter Faculty mentor: Richard Hofstetter, College of Engineering, Forestry and Natural Sciences (CEFNS) Novel Acoustic Technique to Control Bark Beetles Outbreaks of bark beetles are one of the most significant biotic disturbances to forest ecosystems, and typically lead to extensive economic losses, complete transitions of forest communities, and negative impacts on local recreation and forest usage. New acoustic technology has the potential to minimize some of the impacts of these species in trees. Our objective is to create acoustic inputs to deter bark beetles from entering healthy trees, and to test the efficacy of the acoustic devices for management and controlling bark beetles. We tested two hypotheses: (1) Acoustic treatments will influence entry of bark beetles into trees; (2) Specific sounds affect bark beetles differently. Hypothesis 1 was partially supported, and Hypothesis 2 As of 4-19-13 UG Symposium Presentation Abstracts was supported by this study. The ‘wood borer’ sound treatment reduced colonization rate of the pioneer sex of D. frontalis and D. brevicomis. Also, the ‘stress’ sound treatment reduced colonization of D. frontalis beetle, and the ‘artificial’ sound increased colonization of D. brevicomis beetles. None of the acoustic treatments had an effect on entry by Ips pini. This technology could add to the arsenal of tools forest managers use to control bark beetles, provide one of the few non-chemical and environmentally friendly methods of bark beetle control, and expand the usage of this device for wood infesting insect pests in the western and southern United States. Albano, Dominic Federico Martolini, Danny Miller, Dirk Prather, Bander Almazroua Faculty mentor: , College of Engineering, Forestry and Natural Sciences (CEFNS) 40 Qt. Cooler Design This Senior Design Project centers around a product provided by a local business in Flagstaff, AZ called Canyon Coolers. They provide premium, high end coolers for outdoor enthusiasts all over the world. Unfortunately some of their products suffer minor defects originating from design such as inconsistent surface finish, incorrect tolerance between components, and latch failure which can all cause intolerable losses in profit. After client discussions it was determined that a new design for the 40 qt. model was desirable. The new design needed to be compatible in a wider range of uses, weigh less than 7 kg, withstand higher impact stresses, integrate numerous usable features, and yet maintain the current cost of the existing design ($189.99). The finished cooler design satisfies all the project constraints described above. This new design drastically improves upon the existing cooler in many ways. It features various through slots located on the body and lid that allow the user to secure the cooler in various configurations. An integrated hinge design increases durability while allowing the cooler to open even when the backside is flat against a surface. Features have been recessed to reduce stresses on normally exposed components such as latches and feet. The ergonomic latching system provides a secure a seal from body to lid improving ice retention, and every surface of the cooler has smooth geometry transitions ensuring consistent quality of the product. The improved 40 qt. cooler should alleviate current product issues at Canyon Coolers. Aldridge, Megan Faculty mentor: Vicki Ross, College of Education (COE) Fifth Grade Fractions and Assessment: An Action Research Project The intent of this research project was to assess students’ procedural knowledge on solving problems involving fractions. Specifically, the assessment provided was targeting the Arizona CCSS fifth grade math standard 5.NF.1: add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. In order to assess this standard, a pre-assessment of eight problems dealing with fractions was assigned to fifth graders at Sonoran Sky Elementary School. The fifth graders had not yet been exposed to operations with fractions in their classes when they received this assessment. After Dr. Ross’s As of 4-19-13 UG Symposium Presentation Abstracts ECI 300 classes worked with these fifth graders for their practicum experience, a postassessment was given, which consisted of the same problems on the pre-assessment in order to determine the students’ progress. The students excelled at adding and subtracting mixed numbers with like denominators, but when unlike denominators were thrown into the questions, the students overwhelmingly did not know what to do. According to the results of these assessments, students have not yet mastered the standard 5.NF.1: add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. Alling, Erica Faculty mentor: Nashelly Meneses, Russell Benford, Stephen Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) Factors Affecting the Species Abundance and Richness of Fish in Seagrass in the Saipan Lagoon Seagrass ecosystems are among the most productive in the world. Their role as fish nurseries has been described throughout their range, but a notable omission is fisheries-dependent Saipan. In Saipan, two species of seagrass (Halodule uninervis and Enhalus acordoides) could contribute to fish nursery productivity but are susceptible to fragmentation from algae and sand. To address this, I quantified the number of fish species and individuals and the level of fragmentation along transects at sites where each species of seagrass was abundant. I report the following main findings: 1) Higher species richness and abundance of juvenile reef fish (N = 32, X2 = 9.40, P = 0.002; N = 32, X2 = 14.26, P = 0.0002; respectively) and all fish (N = 32, t = 5.59, P = 0.0001; N = 32, F = 77.75, P = 0.0001; respectively) in H. uninervis meadows. 2) The abundance of juvenile reef fish and all fish in H. uninervis meadows decreases with higher fragmentation (N = 16, R2 = 0.62, P = 0.0003; N = 16, R2 = 0.44, P = 0.002; respectively). Species richness and abundance of fish is higher in H. uninervis meadows, but it is negatively affected by habitat fragmentation. This suggests that management for increasing size and abundance of H. uninervis seagrass meadows and reducing sand and algae fragmentation would benefit fisheries in the Saipan lagoon. Allred, Eric Alexandra Clitso, Chelsie Kekaula, LeAndra Marris, Makenna Sowards, Jacob Weaver Faculty mentor: Cassandra Dakan, Honors Program Cultural Diversity and Global Community This panel explores the dynamics of "global community" - and asks "Is this possible?" Specifically, topics explore what different worldviews have in common, modern innovations that build cultural bridges, ego, compassion, empathy and humor across cultures, and the risks of labeling. Ames, Colton As of 4-19-13 UG Symposium Presentation Abstracts Faculty mentor: Anne Scott, Honors Program M, Q, Moneypenny, and Leiter: Bond’s Close Friends and Associates As a secret agent whose covert operations span the decades, James Bond requires the help of a network of scientists, associates, and other intelligence officers to accomplish his top secret goals. M., Q., Miss Moneypenny, and Felix Leiter all aid Agent 007 in many different ways, and Bond could certainly not pull off his daunting feats of espionage without their help. If we analyze each character, we see that not only do they do their work for Queen and Country, but they also do it for their sense of companionship with Bond, James Bond. Andee, Lister Marsha Bitsui, Dr. Jani C. Ingram Faculty mentor: Jani Ingram, College of Engineering, Forestry and Natural Sciences (CEFNS) Evaluation of Uranium in Soils Gathered Near Two Abandoned Mine Sites on the Navajo Reservation. The communities of Pinedale and Church Rock (NM) are located in close proximity to two abandoned uranium mines, the Northeast Church Rock Mine (NECRM) and the Quivira Mine (QM). The United Nuclear Corporation operated the NECRM from 1967 to 1982 removing 3.5 million tons of uranium ore. The Kerr McGee Corporation operated the QM from 1974 to 1985 processing 2.5 thousand tons of uranium ore. Consequently, the NECRM and QM were major contributors of uranium contamination in the soil. The purposes of this study were to determine the amount of uranium in the soil and to identify high-risk exposure in the areas near the two abandoned mines. Twenty topsoil samples were collected from Pinedale and Church Rock. The samples were sifted, crushed, digested with acids, and neutralized to determine the amount of uranium. Total uranium determination was conducted with an inductively coupled plasma mass spectrometer (ICP-MS). The results indicate the samples above the natural background level of uranium, suggesting there is contamination near the abandoned mines. Elevated background levels of uranium enhance exposure and potential to affect human health for both the Pinedale and Church Rock (NM) communities. To ensure reproducibility additional testing is being conducted, results will be discussed. We acknowledge the Partnership for Native American Cancer Prevention funded by the National Cancer Institute for supporting this work. Andersen, Genevieve Madeline Lummis, Carina Hall, Roxanne Nottingham, Amy Vogler, Julia Riehm, Holger Scholz, Paul Keim & David M. Wagner Faculty mentor: David Wagner, College of Engineering, Forestry and Natural Sciences (CEFNS) Phylogenetic diversity of Mongolian Yersinia pestis isolates provides historical insights into the dispersal of plague into Mongolia Yersinia pestis is a gram-negative bacterium that is the causative agent of the disease plague. Y. pestis is believed to have caused three massive, historical pandemics, which claimed millions of human lives. Recent phylogenetic analysis of globally diverse Y. pestis strains in conjunction As of 4-19-13 UG Symposium Presentation Abstracts with genomic analysis of Y. pestis samples collected from ancient plague victims indicate that Y. pestis originated in the Qinghai-Tibet Plateau region of China and spread globally via ancient trade routes. Due to the clonal nature of Y. pestis, clear geographic patterns can often be phylogenetically observed as Y. pestis spreads spatially. Based on the proximity of Mongolia to the location of Y. pestis origin, we expect that plague was introduced to Mongolia on multiple occasions throughout time resulting in vast amounts of genetic diversity when compared to other regions. In an attempt to further understand Y. pestis diversity in Mongolia, we have placed 52 Mongolian isolates on a worldwide phylogenetic tree using canonical SNP data generated through whole genome sequencing. The resulting phylogenetic data indicate that Y. pestis has indeed been introduced into Mongolia multiple times and that these introductions may be linked with major, historical outbreaks such as Justinian’s Plague (~500 AD) and the Black Death (~1350 AD). Anderson, Alexus Anisa Padilla Faculty mentor: Rebecca Maniglia, College of Social and Behavioral Sciences (SBS) The CSI Effect The CSI Effect is very common within court systems today. Because of the show CSI and those similar, sometimes juries have wrongful assumptions about how much bearing evidence really has on a case. This project is to inform those the actual ramifications that evidence has on convicting a suspect. It relays how television asserts the misinformation of how reliable evidence really is. It also gives statistics on how jurors convict due to their new found knowledge. The CSI effect is very prominent within our justice system and proper education is needed to better our system as a whole. Anderson, Amy John Jowers, Daniel Hamill, Gabe Murray, Nathaniel Lail, Annalise O'Toole Faculty mentor: Wilbert Odem, College of Engineering, Forestry and Natural Sciences (CEFNS) Alternative Landfill Capping System Cinder Lakes Landfill in Flagstaff, AZ is looking at alternative ways to use paper pulp sludge, a waste product from a local tissue producing company. The Landfill receives about 40,000 tons of pulp each year and uses a fraction as alternative daily landfill cover. Due to the large amount of pulp being wasted, the Landfill wants to determine if it is feasible to generate cost savings by using pulp in new ways instead of burying it with incoming waste. Cinder Lakes Landfill in Flagstaff, AZ is looking at alternative ways to use paper pulp sludge, a waste product from a local tissue producing company. The Landfill receives about 40,000 tons of pulp each year and uses a fraction as alternative daily landfill cover. Due to the large amount of pulp being wasted, the Landfill wants to determine if it is feasible to generate cost savings by using pulp in new ways instead of burying it with incoming waste. Pulp material characteristics were investigated first to identify its characteristics and possible new uses at the Landfill. Literature reviews showed the material has a low hydraulic As of 4-19-13 UG Symposium Presentation Abstracts conductivity, necessary for use in a landfill permanent cap or liner, but insufficient structural strength. Further tests conducted on the pulp determined it can minimally retard gas flow and adsorb some contaminants in leachate. After material characteristic testing was complete, a landfill cap was tested. Several materials were tested in conjunction with pulp to create viable landfill cap materials. Admixtures of coal fly ash, wood ash, and pulp were created for two different cap layers, a hydraulic barrier layer and a random fill layer. By using these two layers instead of soil and synthetic barrier layers outlined in the Landfill facility plan, the Landfill should save $8,291,677 on material costs alone. Aranda, Stephen Faculty mentor: Sheryl Howard, College of Engineering, Forestry and Natural Sciences (CEFNS) (7,4) Hamming Code Error correcting codes are used to correct errors that occur when transmitted data is corrupted with noise. Normally, all codewords are equally-likely. However, if the data is non-uniform and correlated, such as in environmental sensing networks, the codewords will also be non-uniformly distributed; some codewords are more likely then others. The (7,4) hamming code is used here on non-uniform (4 bit) data that is Gaussian-distributed and has low variance. An important parameter of an error-correcting code is the Hamming distance, which measures the number of bits that differ between one codeword and another. The minimum Hamming distance of a code determines its error-correcting ability, and a larger minimum Hamming distance results in greater error correction. As some codewords are very unlikely, we have the opportunity to swap codewords that are likely but have low hamming distance with unlikely codewords that have a greater distance, to improve performance. Swapping of the codewords to increase hamming distance among more-likely codewords is called codeword mapping. MatLab simulations of the (7,4) hamming encoding with double codeword mappings and decoding were run. Four different double codeword mappings are simulated to determine which provides the best performance. Aranda, Stephen Aniza Brown, Derek Benallie, Brendan George, Micheal Young, Justin Cummings Faculty mentor: John Tester, College of Engineering, Forestry and Natural Sciences (CEFNS) Urban Electric Vehicle for Efficient Green Transportation Advancements in technology and global warming have caused electric vehicles to be viable alternative methods of transportation. Society’s attempt to shift its energy dependence to renewable alternatives is due to the fact that fossil fuels are depleting, causing gas prices to increase daily. The Eco Car team will be competing in the Shell Eco-Marathon. The concept of the competition is to assist in the innovation of electric powered vehicles by designing the most energy efficient vehicle. To accomplish this, the team improved last year’s vehicle and redesigned the electrical system using electrically efficient parts, as well as redesigned a lighter fairing. In order to improve the vehicles efficiency, the team has included a data acquisition unit to monitor efficiency and to detect any problems. Technological innovation in electric vehicle As of 4-19-13 UG Symposium Presentation Abstracts design will change the future by reducing dependency on fossil fuels by producing economically efficient and environmentally friendly vehicles. Aros, Kelli Faculty mentor: Women's & Gender Studies, College of Social and Behavioral Sciences (SBS) Globalization of Beauty In my presentation I will be discussing the history of cosmetic companies and how they formed a globalization of a westernized beauty. A westernized beauty is portrayed as being white, skinny, however with curves, blonde and with blue eyes. With this I will be researching how this westernized ideal of the perfect body for women is expressed throughout magazines and the media over the world. The women of our world are now concentrated on one thing, and that is how they appear to the human eye, and since they are seeing one image in the media, women are seeking cosmetics and plastic surgeries to conform to this westernized ideal of beauty. Arvidson, Garrett Garrett Arvidson Faculty mentor: Gretchen Gee, College of Social and Behavioral Sciences (SBS) UN Involvement in Genocide My paper will focus on issues relating to genocide and, more specifically, the differences between cases in which there is UN involvement and those in which there is not UN involvement. The broadest focus of this paper could be summarized in the question, when does UN intervention in a troubled state become an infringement of sovereign equality? I will delve into the controversial issue of securing human rights in cases of genocide versus the right of state to control matters within its own borders. Throughout the paper I show that although it may initially seem that UN intervention into states experiencing bouts of genocide is beneficial, in many cases this intervention is an infringement of sovereign equality. The cooperation of member states within the UN, and in many cases the disputes or problems that arise between these members, have fascinating and very important effects on certain populations or the world as a whole. These disputes can be the difference between life and death for thousands of people. Ashcroft, Amarah Dorothy Alexander, Amanda Ryan, Paige Warner Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) Drug Use and the Significance of Life-milestones The rationale of the current study is based on findings that drug use affects an individual’s perception of the significance of life milestones. More specifically, this study was used to determine whether the onset and frequency of drug use has a significant effect on an individual’s perception of the significance of traditional life milestones, such as marriage and a steady career. The sample included currently enrolled Psychology 302W students, mostly female of European- As of 4-19-13 UG Symposium Presentation Abstracts American ancestry. Methods included these students to complete a questionnaire. The questionnaire assessed drug use history and frequency and also asked students to rate their personal perception of each life milestone on a Likert-type scale of 0 to 5, with zero not being important at all and five being very important. Anticipated results of the study will be that the onset of drug use and the frequency of drug use will skew an individual’s perception of traditional life milestones. Atchison, Stephanie Courtney Biggar, Kevin Lasky Faculty mentor: Joshua Hewes, College of Engineering, Forestry and Natural Sciences (CEFNS) Evaluation of New Bridge for the Flagstaff Urban Trail in Picture Canyon The goal of the project is to determine the best solution for the replacement of a wooden walkway bridge located in Picture Canyon, crossing the Rio De Flag northwest of the Wildcat Hill Waste Water Treatment Plant, at the junction of three separate trails. The Arizona Trail, the Flagstaff Urban Trail System, and the Educational Loop Trail all connect at one location where a small (15-feet wide) pedestrian bridge is currently located. The main replacement bridge under consideration is an old Burlington Northern Santé Fe (BNSF) railway bridge. This replacement bridge is 16-feet by 80-feet. The project has focused on structural evaluation of the bridge and a site layout containing this bridge. Austill, Donovan Ryan Byerrum, Seyrra Croy Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) Music's Effect on Emotion The current study is examining the different effects music can have on emotions. Specifically, the experiment was designed in order to examine if different genres of music can elicit different feelings and emotions. The participants in this study were psychology students taking the research methods class (PSY302W). Participants were taken from their classes and were instructed to take an anonymous survey (Geneva Music Emotion Survey) regarding their emotions. One 302w class took the survey while a happy song was playing. One 302w class took the survey while a sad song was playing. Finally, a third class took the survey while no music was playing in order to establish a base line. The survey was used to measure the emotions, and overall happiness of the participants. The results from the surveys were compared in order to examine if the different groups felt different levels of emotions. It is expected that participants exposed to happy music will have recorded higher emotions than the baseline group, and participants exposed to sad music will have recorded sadder emotions than the baseline group. Avila, Jacob Spencer Courtney Haasch, Samuel Kirschbaum, Kevin McLaughlin, Carl Thomson, Liz Tomaschko Faculty mentor: Cassandra Dakan, Honors Program As of 4-19-13 UG Symposium Presentation Abstracts Pro-social Behavior This panel explores a range of pro-social behaviors in everyday interactions, and the overlap of behavioral variables, including self-compassion and mental illness, gender and compassion, emotion in literature, duality in humans, compassion and conflict, and quiet ego. Avila, Vianey Faculty mentor: Diane Angell, College of Engineering, Forestry and Natural Sciences (CEFNS) The Role of Small Mammals as Seed Predators in Prairies Prairies are one of our most diverse ecosystems, and today, less than one percent of native prairie remains. Prairies are important ecosystems because of their high biodiversity, potential to increase soil organic matter and store carbon. Due to the decline in prairie communities, many prairies are being planted on lands previously used for agriculture. Small mammals such as voles and mice have the potential to affect prairie communities during and after the restoration process by foraging on seeds and plants as communities mature. For example, seed predation can affect the survival and germination of seeds and alter the composition of seed pools when one species of seed is harvested more than another. We used cafeteria-style seed cards and incorporated camera traps in order to observe seed predators and determine seed preference in both a remnant and restored prairie in Minnesota during the months of June and July. Live-trapping also provided information on the small mammal communities in both prairie types. The small mammal community captured by the camera traps was quite different from those caught in live traps. Small mammals at both locations had similar seed preferences. Although heavier or larger seeds with higher energy content are often preferentially selected, we found a negative relationship between seed removal rate and seed weight. Overall, stiff goldenrod was removed most quickly and western spiderwort was removed least often. Understanding the degree to which small mammals affect seed pools may highlight the ways these small herbivores affect the restoration of prairie plant communities. Bade, Nolan Faculty mentor: Peter Friederici, College of Engineering, Forestry and Natural Sciences (CEFNS) Integrating Art and Science Methodologies: Creating artifacts that re-evaluate ecosystem relationships on the Milwaukee River Effective societal response to an environmental challenge, such as ecosystem degradation, is often difficult when science is the major communication medium (e.g. climate change inaction). Rather, societal challenges are addressed most efficiently when “four cultures” of environmental science, creative arts, philosophy & religion, and social science engage fully and equally with each other. The Urban Ecology Center (UEC) (Milwaukee, WI) and connected riparian system were used as an experimental study area in connecting the four cultures through the production of a dozen artifacts (Urban (Re)cology) that document present, past, future, and alternative ecological landscapes. A Practice-Led artistic research method and feedback environmental art method were used to investigate natural and religious metaphors, symbols, and aesthetic design As of 4-19-13 UG Symposium Presentation Abstracts theory. Native Americans from pre-Wisconsin Territory colonial period influenced the future social and physical construction of the Milwaukee parks system/river infrastructure, and the appropriation of natural resource use (water, copper, lead) through time. Additionally, Reed Canary Grass (Phalaris arundinacea), Garlic Mustard (Alliaria petiolata), and Lead Plant (Amorpha canescens) have well-established sociopolitical networks – beginning at colonial contact. The landscape and how it is used is shown to predispose the production and meaning of ecological vocabulary (e.g. “invasive” or “native” or “natural” ecosystem), which then can determine how the land is managed, and the public’s perception of what the environmental challenges are (and how they started). The Urban (Re)cology project is a baseline for art-science integration, and is currently being used as an installational teaching tool. Badertscher, Lauren Faculty mentor: Adam Hoffman, Kerri Quinn, Honors Program Conservation and Poverty: Successful Compromise in Central and Southern Africa The paper to be presented discusses the importance of communication portion of the planning and implementation of combined poverty reduction and conservation programs in various nations in southern Africa. Three specific examples, the Umango Project Area in South Africa, Korup Project in Cameroon, the Londolozi Game Reserve in South Africa, and Kenya’s Masai Mara National park, are discussed in relation to their success in both the fields of conservation and poverty reduction and the role of communication in the successes and failures of each instance. While each example tried to promote conservation and poverty reduction, the Korup project failed to facilitate communication between locals and administrators of programs leading to a lack of cooperation and the projects ultimate failure. Kenya’s Masai Mara and its surrounding communities have found some higher level of success, but a lack of planning allowed corruption to hinder poverty reduction and lead to the deterioration of conservation goals. Finally, The Londolozi Game Reserve and Umango project have combines successful planning and communication in order to reach success, though through slightly different means. Combined, the examination of various programs is used to demonstrate the importance of the inclusion of locals in the planning and implementation of conservation and poverty reduction programs through the establishment and continuation of communication between locals and planners. Bagherpour, Daniel Cameron Fule, Katie Lumia, Jose Marmolejo, Sophie David, Zac Quatre Faculty mentor: Geeta Chowdhry, College of Social and Behavioral Sciences (SBS) Dalit Discrimination and Movements for Change in India Our Presentation will introduce the audience to the modern struggle of Dalit’s within India’s historical context of social inequality and oppression. Research by government sites, non-profit organizations, and academic institutions will be analyzed and shared along with examples found in Indian newspapers and political documents. Findings regarding measures Dalit’s and the Indian Government have taken to promote equality will be presented. Our presentation concludes As of 4-19-13 UG Symposium Presentation Abstracts with the significance of socio-political change within India as Dalit’s pursue greater representation. Bagwell, Brittany Kali C. O’Connor, J. Richard Coast Faculty mentor: J. Richard Coast, College of Engineering, Forestry and Natural Sciences (CEFNS) Assessment of Accuracy of a Whole-Body Plethysmograph in Pulmonary Function Testing Body Plethysmography is a useful tool for measuring lung volumes and capacities. A recentlyacquired plethysmograph was evaluated for accuracy and reproducibility by comparing its output to those of validated techniques in the laboratory. Pulmonary function measurements from the plethysmograph were compared to those of a Collins 13L spirometer. We tested the hypothesis that the output from the plethysmograph will not be different from that of the bell spirometer, and these measurements were repeatable using the plethysmograph. The study evaluated 10 healthy, non-smoking subjects (5 male, 5 female) ranging from 18 – 59 years-old. Lung volumes were first measured with the body plethysmograph. A forced vital capacity (FVC) maneuver was performed on a bell-spirometer to obtain the measurements for comparison. A test was also performed to look at repeatability with the plethysmograph over different days. Paired T-tests were performed on data obtained from the spirometer compared to the data from the plethysmograph. The two trials on the Plethysmograph for repeatability as well as the differences between the plethysmograph and spirometer were not significantly different from one another. It can be assumed that the data from the plethysmograph is repeatable and there was no difference in FVC or FEV1.0 between the plethysmograph and the spirometer. Bahe, Whitney Faculty mentor: Micheal Larma, College of Social and Behavioral Sciences (SBS) Origin of the Navajo Police My research project will be about how the formation of the Navajo police came to what it is now. I will be interviewing elders and referencing other sources that will contribute to my project. Baker, Allison Faculty mentor: Lauren Berutich Campus and Community Based Action Research Teams FYSeminar Program, University College, University College Action Research and Engaged Learning: S. N. A. I. L. Fostering just and sustainable communities in northern Arizona through engaged learning, community partnerships, and action research As of 4-19-13 UG Symposium Presentation Abstracts A component of CRAFTS (Community Reengagement for Arizona Families, Transitions, and Sustainability), the Campus and Community Based Action Research Teams (CBARTs) create dynamic intergenerational hands on learning communities, bringing first year seminar students, returning undergraduates, masters students in the sustainable communities program and community partners into a collaborative relationship. There are over 10 Action Research Teams, a range of 250 to 500 undergraduate students and 20 SUS grad students participating both on and off campus in the areas of social, environmental, and economic justice issues. FYSeminar courses offered with an ARTs component exposes students to a unique pedagogical approach to hands-on, experiential learning of which content, skill set development, action research and student engagement are fruitfully intertwined and connected. This spring, each team is posed with the question, “What is Action Research?” and how does this work connect to community engagement, civic learning, and collaboration. Each poster will answer this question and share how Action Research has engaged students in hands-on experiential and civic engagement throughout the semester and year. Baker, Eileen Torrey Gross, Christian Loritz, Peter Massey, Chris Wieduwilt, Derek Young Faculty mentor: Cassandra Dakan, College of Arts and Letters (CAL) Governments, Economies and Better Societies This panel explores contemporary social/politcal/economic movements in general, and specifically protest in South Korea, consumerism, dictatorships, the Communist ideal, resistance to Nazisim, and economic disparity. Banister, Kelsey Kayla Ochoa Faculty mentor: Stephen Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) Revisiting Self-Fertilization and Outcrossing in the Leech Helobdella stagnalis The relative tendency for the hermaphroditic leech, Helobdella stagnalis to outcross or selffertilize is poorly understood. In order to establish the leeches’ capability to self-fertilize, an experiment was conducted where individuals were either isolated or assigned to mating pairs. The reproductive efforts and fitness of the individuals in both treatments were indirectly measured through the analysis of brood onset, brood size, gestation length, offspring survivorship, and brood development. We expected that there would be significant differences between outcrossing and the inferior method of self-fertilization. However, despite results indicating that self-fertilization is a possible reproductive pathway, preliminary results showed no significant differences between mating systems. Subtle trends, although not significant, were detected and may suggest a small sample size may be responsible for these unusual results. Therefore, the experiment was repeated with an increased sample size to reevaluate the effects of self-reproduction on this H. stagnalis population. We collected leeches from Rio de Flag in Flagstaff, Arizona during September 2012. Once detached from the parent, the offspring of these As of 4-19-13 UG Symposium Presentation Abstracts individuals either remained isolated or were paired that October. If the sample size is increased and Helobdella stagnalis uses self-fertilization as a means for reproduction in the absence of mates, then a difference between the self-fertilization and cross-fertilization reproductive methods will be present. Further experimentation will assess parentage of the offspring using microsatellite markers to verify whether paired individuals are true cross-fertilizers. This research will provide a better understanding of this species, mixed mating systems, parental care, and their evolution. Barnes, Monica Faculty mentor: Dean Smith, Franke College of Business (FCB) Desalination as a Solution for Water Shortages in the West This paper weighs the possibilities of desalination of ocean water as a solution to water shortages in the Western U.S. This paper will also explore the outcomes of a new water market created through desalination of ocean water. Barrios, Avila Faculty mentor: Dean Smith, Franke College of Business (FCB) Utilitarian vs. Non-utilitarian Uses of Water in the West This presentation will focus on the utilitarian and non-utilitarian uses of water in the west. Bashaw, Claire Faculty mentor: Jennifer Musial, College of Social and Behavioral Sciences (SBS) Feminist Leadership and Women in the Workplace While the gap between men and women in the workplace has seems to lessen over decades, it is important to observe that although society deems the gap a “thin” one, it is clearly still present. In my research I will be exploring the many aspects that divide women and men careers and in leadership positions. I will be examining masculinities and men’s attitude towards gender in the workplace and highlighting prevalent problems. I will also be incorporating the importance of feminist economics and its reexamination of the economy for the purpose of improving women’s economic status. Women in leadership positions have improved through a historical lens, but still remain such a small percentage. I am seeking to understand and educate others about the ways women can continue the momentum in rising to the top. Bast, Douglas Faculty mentor: Dean Smith, Franke College of Business (FCB) Washington and Water reclaimation and trasportation As of 4-19-13 UG Symposium Presentation Abstracts This presentation covers how Washington transports water and what different techniques they are working on to transport or reclaim water. Baumgartner, Brett Faculty mentor: Dean Smith, Franke College of Business (FCB) Desalination and the Rising Cost of Water The rising cost of water is predicted to continue indefinitely; thus, desalination on a large-scale basis is becoming more and more of a feasible alternative.

Bechok, Elizabeth Jacob Erickson Faculty mentor: Lauren Berutich Campus and Community Based Action Research Teams FYSeminar Program, University College, University College Action Research and Engaged Learning: Foodlink School Gardens Fostering just and sustainable communities in northern Arizona through engaged learning, community partnerships, and action research A component of CRAFTS (Community Reengagement for Arizona Families, Transitions, and Sustainability), the Campus and Community Based Action Research Teams (CBARTs) create dynamic intergenerational hands on learning communities, bringing first year seminar students, returning undergraduates, masters students in the sustainable communities program and community partners into a collaborative relationship. There are over 10 Action Research Teams, a range of 250 to 500 undergraduate students and 20 SUS grad students participating both on and off campus in the areas of social, environmental, and economic justice issues. FYSeminar courses offered with an ARTs component exposes students to a unique pedagogical approach to hands-on, experiential learning of which content, skill set development, action research and student engagement are fruitfully intertwined and connected. This spring, each team is posed with the question, “What is Action Research?” and how does this work connect to community engagement, civic learning, and collaboration. Each poster will answer this question As of 4-19-13 UG Symposium Presentation Abstracts and share how Action Research has engaged students in hands-on experiential and civic engagement throughout the semester and year. Begay, Merle Faculty mentor: Michael Lerma, College of Social and Behavioral Sciences (SBS) Strengthening Indigenous Relationships through Language This presentation will offer perspectives regarding the importance of verbal communication, and the association it has to maintaining links to: origins and continuance from an Indigenous perspective. Indigenous life ways reflect the relationships between humanity; nature; and spiritual connectedness by means of language. The application of traditional Indigenous languages in the 21st Century, symbolizes the harness to which each distinct indigenous culture, continues to sustain their ties to their existence in humanity; nature; and spirituality. Indigenous cultures strengthen this continuation through songs, prayers, and the practice of indigenous orality. Beloin, Kyle Coren Frankel Faculty mentor: George Reudebusch, College of Arts and Letters (CAL) Action and Compassion: Aristotle on Political Science Looking at Aristotle's work from the perspective of a political scientist raises several important and, furthermore, relevant implications for contemporary political theory. For example, Aristotle's notion of the "nous" provides a foundation on which a substantial political science ought to be based. Additionally, the role political participation plays in Aristotle's framing of moral excellence and practical reason suggests that our current political institutions in the U.S. might fall short in bringing about this proposed foundation for political science. What unexpectedly emerges from these inquiries, however, is the shared notion that our practical experiences in philosophy play a crucial role in demonstrating and informing our anticipated goals: to not only identify in Aristotle an idea that civic engagement and public discourse are necessary to attaining both intellectual and moral excellence, but show that we can envision how exactly we can apply Aristotle's ethical framework in communities, and more generally, society. Belus, Matthew Faculty mentor: Bruce Hungate, George Koch, College of Engineering, Forestry and Natural Sciences (CEFNS) The Effects of Abiotic Conditions on Soil Fungal Communities over a Decadal Timescale In the American Southwest, climate change is expected to increase the intensity of drought and elevate temperature. In Flagstaff, Arizona a natural elevation gradient exists where conditions associated with climate change in the South West can be simulated. The C. Hart Merriam Elevation Gradient was utilized to transplant soil communities down gradient to simulate climate As of 4-19-13 UG Symposium Presentation Abstracts change in ecosystems representative of the Southwest ten years ago. Intact micro-ecosystems were transported down gradient in sunken plastic cylinders 30 cm in diameter by 40cm deep for each control and experimental site. The experiment was designed to determine how soil communities are affected by hotter and drier conditions in the Mixed Conifer, Ponderosa Pine, Pinion Juniper, and Desert Grassland life zones. Soil was sampled in 2011 from each control and experimental soil core to compare differences in control and experimental soil fungal communities. We used Quantitative Polymerase Chain Reaction (QPCR) and Pyrosequencing of ribosomal DNA to compare the abundances of different taxonomic groups of fungi. Statistical analysis of these fungal communities after a decade of altered temperature indicates that all four ecosystems, control and experimental, are statistically different. All samples show unique soil fungal community structures in each control and experimental micro-ecosystem. Experimental ecosystems, those transplanted down gradient, are statistically different from both initial and transplant ecosystems. The differences in fungal communities after a decade of manipulation indicate a longer timescale for ecosystem adaptation than previously thought. Benefield, Jerod Faculty mentor: Karen Haubensak, Richard Hofstetter, College of Engineering, Forestry and Natural Sciences (CEFNS) Who’s Bugging Out?: The Impacts of Mechanical Thinning on Arthropod Communities in Northern Arizona, USA Mechanical thinning is a widely used forest management tool in the southwestern United States. Decreasing stand densities, or the number of trees per acre, are known to increase understory production in terms of both vegetation abundance and richness. The effects of these postthinning condition changes on macroarthropod communities within soil and litter food webs are not currently known. My goal is to quantify insect community responses to the understory vegetation changes induced by mechanical thinning treatments. Stand characteristics and pit trap samples were collected from 16 sites (8 mechanically thinned, 8 unmanaged) during the premonsoon month of June and the post-monsoon month of September during 2012. Samples were analyzed in the lab and arthropod specimens were categorized according to functional guilds. Based on cascading trophic level responses to changes in understory vegetation within thinned sites, we expect to observe distinct differences within macroarthropod community assemblages between mechanically thinned and unmanaged sites. As drivers of nutrient cycling and decomposition within forest ecosystems, arthropod communities and their responses to habitat manipulation should be studied to ensure responsible forest management and better understand landscape level changes from forest thinning. Benton, Richelle Rhiannon Bucher Faculty mentor: Lonnie Wederski, College of Health and Human Services (CHHS) Disinfectant Techniques This poster is a presentation of research to compare the effectiveness of disinfectant techniques used in hospitals to clean intravenous line injection ports and arterial line access ports. Arterial As of 4-19-13 UG Symposium Presentation Abstracts and venous lines increase the risk of catheter related sepsis, a nosocomial infection that may lengthen one’s hospital stay and increase costs of healthcare. Current policy from Kingman Regional Medical Center was reviewed and research was completed to determine if adding chlorhexidine gluconate to isopropyl alcohol resulted in more effective prevention of bacterial growth on intravenous and arterial lines. Research showed that KRMC was in compliance with current FDA guidelines for disinfection of ports and that while 70 percent isopropyl alcohol was effective in reducing bacterial growth, chlorascrub, 70 percent alcohol with an addition of 3.4 percent chlorhexidine gluconate, is more effective in preventing bacterial growth and impedes growth for a longer period of time. Bergen, Krystal Faculty mentor: Applied Indigenous Studies Dr. Octaviana Trujillo, College of Social and Behavioral Sciences (SBS) Silent Death: Abandon Uranium Mines in Cameron, AZ My presentation is focused on the silent death of uranium mining in my community. The story of the Navajo monster, leeso (uranium) strikes the Navajo community of Cameron. Through news articles, documentary, and research it gives a strong indication of the effects of abandon uranium mines. The radiation level is at shocking levels of great concern to anyone that lives near it. The pattern of lack of involvement from the federal level with the Department of Energy and Environmental Protection Agency. Recent research was done with Abandon Uranium Mines in Cameron by Tommy Rock, and provides information on the current status of abandon uranium mine and the health effects. Through my internship with the Applied Indigenous Studies Department, I am doing an internship with NAU Chemist, Dr. Jani Ingram and Tommy Rock with researching on sheep in the Cameron area, and the uranium effects. There has been research completed on soil sampling and water sampling. Research on sheep that are close to the abandon mines has not been done. The Navajo people have been butchering and consuming sheep most of their lives and the abandon uranium mines may be causing harm to those who consume the sheep. Through this research, it gives me more awareness of the science portion of abandon uranium mines and the harmful effect to my community. It is to take care of my relatives who continue to live in the Cameron and to find the values this community is seeking. My discussion will be the history, environmental policies, research, and my nation building effort to help my community. Bigelow, Jessica Faculty mentor: Thomas Paradis, College of Social and Behavioral Sciences (SBS) Integrating GIS technology and Digital Gaming into K-12 Geography Education I'll be presenting on the techniques being used with regards to GIS technology and digital gaming in a K-12 classroom. I will give information on the research that's been done by other academics and researchers, use examples from my own research, and provide suggestions for future research. I've gathered my information through surveying students in a high school, interviews of two high school teachers, as well as observation of the teaching techniques being used. As of 4-19-13 UG Symposium Presentation Abstracts Bishop, Michael Faculty mentor: Christopher J. Mann, College of Engineering, Forestry and Natural Sciences (CEFNS) A Next Generation 3D Imaging System for Ballistics Identification Firearms are the most commonly used weapons in violent crimes, and the bullets and shell casings ejected from a given firearm have a unique signature or pattern stamped into them as a result of the firing process. This signature can potentially be used to tie a bullet or shell casing back to a specific firearm, and hence to a specific individual that may have committed the crime. Current ballistics identification technology employed by the federal and local law enforcement communities has several problems that reduce the utility and accuracy of existing systems, including outdated 2D ballistic imaging technology, and inaccuracies in the automatic signature matching algorithms. This research project attempted to develop the next-generation ballistics identification technology by employing novel quantitative 3D microscopy methods for ballistics imaging, and state-of-the-art pattern 3D matching algorithms. The development of a next generation 3D imaging instrument with advanced and tested pattern matching capabilities aligns very well with the current need for achieving reliability, reproducibility, selectivity, and/or sensitivity for firearms forensic analysis. With the help of my mentor Dr. Christopher J. Mann, and the Hooper Undergraduate Research Award work was done to advance firearms identification science by aiding the firearms examiner and providing them with quantifiable and reliable tools which make their analysis as objective and accurate as possible. Black, River Jason Wilder Faculty mentor: Jason Wilder, College of Engineering, Forestry and Natural Sciences (CEFNS) Identifying Novel SNPs in the 3’UTR of KRAS Using Native American DNA Samples Mutations that upregulate the expression of the oncogene KRAS have been linked to pancreatic cancer. Such mutations affect growth promoting signals, which in turn increases the production of key proteins involved in cellular division. MicroRNAs, or short sequences of nucleotides that have been shown to dysregulate similar genes, are a factor hypothesized to be affected by mutations in the genome of individuals afflicted with cancer. We sequenced sections of the 3’ UTR of KRAS in 41 Native American DNA samples, and compared the single nucleotide polymorphisms found using public databases to identify novel mutations. This was done to search for unique SNPs that could influence microRNA binding sites. Our research has shown that novel SNPs are present within the 3’ UTR of various sample subjects. Blackman, Ryan Faculty mentor: David Trilling, College of Engineering, Forestry and Natural Sciences (CEFNS) Using Thermal Modeling to Determine the Properties of Small Solar System Bodies As of 4-19-13 UG Symposium Presentation Abstracts Much can be learned about the origin and evolution of the Solar System through the study of small objects such as asteroids and comets, provided their physical properties can be known. This can be accomplished through a technique called thermal modeling, in which the thermal radiation from these objects is captured by telescopes that observe in the infrared part of the electromagnetic spectrum. Thermal models help us analyze this radiation so that we may solve for physical properties of the observed objects such as size and albedo (the percentage of sunlight reflected off the object). Using data from NASA's Wide-Field Infrared Survey Explorer, I have derived these properties for a number of bodies classified as Centaurs, which exhibit characteristics of both asteroids and comets. These small objects have estimated lifetimes of only a few million years and have unstable orbits that cross one or more of the giant planets. I have also made comparisons of their properties with those of other groups of small Solar System bodies in an attempt to understand more about the origins of these objects. Blanford, Matthew Kristen Waring and Adam Polinko Faculty mentor: Kristen Waring, College of Engineering, Forestry and Natural Sciences (CEFNS) Seedling Growth Response to Western Spruce Budworm in Mixed Conifer Forests The western spruce budworm (WSBW), Choristoneura occidentalis, has been a native forest defoliator in western North America since the late 17th century. In northern New Mexico, the WSBW has been at elevated population levels for a prolonged time period (>20 years in some locations). Under the current WSBW outbreak and a changing climate, projected to be warmer and drier in the Southwest, there may be long-term changes in forest stand structure and composition. The focus of our research is to investigate understory seedling response to change in overstory structure and resource allocation resulting from WSBW-caused mortality. In August, 2012, we sampled 45 tree seedling pairs in dry mixed conifer stands currently experiencing mortality from WSBW. Each pair included one seedling susceptible to WSBW (i.e., white fir or Douglas-fir) and a non-susceptible, neighboring seedling (i.e. ponderosa pine). Our measurements included 5- and 10-yr height growth, crown length and ratio, and defoliation severity (where appropriate) and/or other damages. Paired t-tests will be used to test for significant differences between tree pairs. We hypothesized that in WSBW affected sites the seedlings of non-susceptible ponderosa pine (Pinus ponderosa) will have significantly greater relative height growth than the susceptible seedlings of Douglas-fir (Pseudostsuga menziesii) and white fir (Abies concolor). Ponderosa pine is also more drought tolerant than the susceptible species, and likely to be favored under warmer, drier climatic conditions as well. The predicted change towards a drier climate is supposed to be most in the region of northern New Mexico. We will present the results from our data and initial implications for management, including potential future species compositional shifts and stand development trajectories. Natural resource managers will be able to use our results to begin understanding the implications of WSBW mortality on forest composition and structure, enabling managers to incorporate these changes into adaptive management strategies. Blaser, Liz As of 4-19-13 UG Symposium Presentation Abstracts Kaitlin Rosser, Katelyn Wyatt Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) Asch Study Duplicate Observing Gender Dynamic Many other researchers have conducted replications of the Asch study on conformity. The current study is also a duplicate of Asch's study. This research, however, explores the relationship between group gender and conformity by manipulating the gender of the group dynamic. Previous research has shown that women are more likely to conform than men. This study looks at four major groups: male confederates with a female participant, male confederates with a male participant, female confederates with a female participant, and female confederates with a male participant. In each trial, participants are asked to answer ten perception questions. Each question consists of an example line and three possible answers, the participants are asked to state which of the lines best matches the example line. The confederates in the group are provided scripted responses in order to persuade the participants answer. The results from this study will identify if a gender-biased environment plays an influential role in an individuals’ willingness to conform to the group. Blount, Mariah Vianney Hoenig, Greg Sale Faculty mentor: Matt Anderson, College of Social and Behavioral Sciences (SBS) Does your culture effect how you choose your mate? This study researched the effects or influences of culture in attractive features when searching for an ideal mate. Undergraduate students at Northern Arizona University were the participants of this study through the use of a survey created by the researchers. The survey utilized a Likert scale from 1(least important) to 7(most important) asking participants which attractive features were most important when choosing an ideal mate. The survey was split into four different categories: facial features, upper body, lower body, and extremities. Researchers predict that there will be a positive correlation between culture and how each picks their ideal mate. Bo, Stevens Faculty mentor: Ophelia Wang , College of Engineering, Forestry and Natural Sciences (CEFNS) Measuring Habitat Loss in Southwestern Nicaragua Nicaragua contains the world’s largest remaining tropical dry forests despite losing half its forest cover since the 1950’s. Habitat loss and fragmentation of these forests have devastating effects on species diversity and habitat connectivity. Characterizing land use and land cover changes for broad conservation planning necessitates the use of remotely sensed satellite imagery. Classification of land cover is being developed using the red, green, and near-infrared spectral bands, the Normalized Differential Vegetation Index from SPOT imagery, in addition to terrain variables, aerial photography, and ground truthing data. The resulting land cover map will be used by local agencies to prioritize areas for reforestation and conservation within the province As of 4-19-13 UG Symposium Presentation Abstracts of Rivas, Nicaragua, benefiting local conservation organizations by recognizing the greatest deforestation contributors and highlighting areas that need urgent conservation effort. Bojorquez Figueroa, Edith Faculty mentor: Melissa Santana, College of Arts and Letters (CAL) "Successful Aging: Creating the Ultimate Assisted Living Environment for people with Alzheimer’s in Provo, UT" The research purpose was to address the question “How to design an efficient assisted living environment that supports and understands the needs of people suffering from Alzheimer’s disease?” Studies have shown that the built environment can have a great effect on the everyday life of an Alzheimer patient and, with an appropriate interior design concept, these patients can live a better life. For this project, a theoretical facility was created in Provo, Utah because of its healthy lifestyle, quality care access, and safety. Due to class constraints only the recreation, garden, employee areas and private spaces for people with Alzheimer’s were researched and designed for. Scholarly journals and case studies were reviewed to determine key elements that would enrich the design of this type of facility. Research showed that environmental enhancements can have a positive impact on the well-being of staff and patients in the mental healthcare field. Other key findings include evidence that exposure to arts may reduce anxiety in patients with Alzheimer’s and that wayfinding problems should be simplified by creating small-scaled settings with simple but not monotonous circulation routes. Based off of research, observational site visits, and healthcare provider interviews a unique and supportive environment was designed. To help create a connection to the local and natural environment the design was inspired by the autumn colors found in Provo. Paintings and images that characterize Provo’s nature helped enhance well-being and diminished stress levels and indirect lighting was used to allow higher light levels without producing glare. Booz, Betty Lou Faculty mentor: Diana Elder, College of Engineering, Forestry and Natural Sciences (CEFNS) Community Sustainability and Non-profit Organizations This presentation is an examination and explanation of the idea of Community Sustainability, and how local non-profit organizations facilitate this movement. In order to fulfill the graduation requirement of participation in an internship, I became an intern at Friends of Flagstaff’s Future, a non-profit organization in Flagstaff, Arizona that is geared towards social sustainability and community-lead advocacy. The purpose of the internship was to understand how non-profit organizations function, while helping a particular non-profit organization, Friends of Flagstaff’s Future, to succeed. During the internship, a concept was developed which analyzed the participation of an individual in the pursuit of a sustainable community. There are several ways in which a person can contribute to the sustainability of their community, such as eating food that has been grown and/or raised locally, shopping at local stores, and helping to keep public spaces clean. Additionally, the importance of non-profit organizations because of their servicebased goals was recognized in the paper. Friends of Flagstaff’s Future, a non-profit organization As of 4-19-13 UG Symposium Presentation Abstracts located in downtown Flagstaff, was studied as an essential part of developing a sense of Community Sustainability within the city of Flagstaff. It is concluded in the presentation that an individual interested in sustainability must adopt a sustainable lifestyle and then contribute to the sustainability of their community. Booz, Betty Lou Mary Coulombe, Jacquelyn Davis, Jessica Eliason, Will Hickman Faculty mentor: Diana Elder, College of Engineering, Forestry and Natural Sciences (CEFNS) A Strategic Plan to Eliminate Plastic Bags in Flagstaff This specific group of students in the Environmental Capstone Class 490C was given the task of creating a strategic plan to eliminate plastic bag use in Flagstaff, Arizona. Plastic bags have presented a significant problem to the natural and human world because of the pollution they create. During the manufacturing process of plastic bags, harmful chemicals are emitted into the atmosphere. Then, when they have outlived their single-use purpose, they are discarded, polluting several different types of ecosystems. Throughout their lifespan, these bags create a nuisance to a society that could do without them. After outreach research, the group was presented with several different avenues through which to complete the goal of eliminating plastic bags in Flagstaff. The option of a bag fee for consumers and an outright ban throughout the city were among those ideas. The group felt it was better to focus on the complete ban of plastic bags. It also became evident that implementing a bag ban would not easily be finished within the timeframe allotted by the capstone course ENV 490C. Therefore, the group members set about creating a survey, petition and fact sheet that might contribute to the success of a bag ban in the future. Included within this project is a complete plan in order for this to become a reality. Booz, Christian Kevin Kirchmeier, Brett Smith, Dion Obermeyer, Eric Nolan Faculty mentor: Diana Elder, College of Engineering, Forestry and Natural Sciences (CEFNS) Challenges in Communicating Climate Change Communicating climate change issues to the public is a challenging task. Reasons include misunderstanding scientific language, educational issues, political beliefs and social stigma, economic uncertainties, and locality in time and place. Scientific language is currently misunderstood by the general public. The definitions of words such as “theory” and “uncertainty” contain different meanings for the scientific and public communities. Scientific education in the United States is lagging behind the rest of the world; this has a direct effect on how the public approaches climate change issues. In addition to environmental education, personal opinions most directly affects perceptions of environmental issues. Reliance upon an economic system demanding mass consumption makes solving the climate crisis even more difficult. The science behind climate change has been communicated by its skeptics as uncertain at best and irrelevant to the current agenda. There is a social stigma surrounding climate change within the political realm, and many politicians shy away from issues not immediately relevant to their term in office. Climate science needs to be As of 4-19-13 UG Symposium Presentation Abstracts communicated in timeframes politicians can get behind without fear of losing elections. Therefore, climate change needs to be communicated in terms of the here and now, rather than emphasizing effects that are decades away. Complexities associated with climate science pose difficulties in communicating with the general public and policy makers. The scientific community can improve its communication of climate change in order to influence public opinion towards recognizing climate science as legitimate, and making the necessary changes for a sustainable future. Booz, Christian Faculty mentor: Cynthia Pardo, Moran Henn, College of Engineering, Forestry and Natural Sciences (CEFNS) Friends of Flagstaff – Outreach Internship Flagstaff boasts a rich and historical culture. Every day, urbanization and increased unsustainable development are decreasing the open spaces and quality of life Flagstaff residents enjoy. Nonprofits are one major way that the Flagstaff area can keep its distinctive culture, one such nonprofit is Friends of Flagstaff’s Future (F3). The purpose of my internship was to understand how the non-profit realm works and better understand how to create actual change in regards to open space and the environment. The main focus of this internship was the research of Flagstaff’s local water issues surrounding a snow park at McMillan Mesa as well as general communications work including the creation of a blog and taking photos of events. By working with F3 I increased by photography and writing skills by running a forum for the Flagstaff public and by photographing basic events and promotional material. The last portion of my internship was working with the KARES (Kids Art, Reading, and Eating for Sustainability) program to teach children about environmental issues surrounding the area. By the end of the internship I gained a better understanding of the non-profit world, increased my writing and technical skills, and gained valuable professional experience in the non-profit realm of environmental activism. Bossaller, Katherine Faculty mentor: Steve Wilson, College of Engineering, Forestry and Natural Sciences (CEFNS) Symmetries of Generalized Circulant Graphs I will explore a new classification of Circulant Graphs namely, C'_n(1,a,b) graphs there general properties and the symmetries they possess. I will prove which of these graphs are edgetransitive and other general properties. Also I will be exploring several generalizations of these graphs and try to prove overall theories about this type of graph. Bostaph, Jessica Faculty mentor: George Gumerman, Honors Program Abusing Food to Reach Perfection As of 4-19-13 UG Symposium Presentation Abstracts In this presentation I will explore the way food plays a role in the lives of girls who struggle with the eating disorder anorexia nervosa. This will include an introduction to the disease itself, how it develops, what influences it in girls, the age groups it most often affects, and how food fits into the picture. What foods do anorexic girls allow themselves to eat, and why? What foods do they avoid and why? The thesis statement for the presentation is: With grumbling stomachs and the aroma of a fresh cooked meal passing through their senses, some girls refuse to eat and nourish their bodies in fear of gaining weight and becoming unbeautiful by media’s standards. This mental disease, anorexia nervosa, affects around 13% of girls at some point in their life. This paper will explore the role food plays in the lives of these affected girls – why are some foods part of the “diet” plan while others are avoided at all costs? Bowen, Ronnie Faculty mentor: Linda Paul, College of Health and Human Services (CHHS) Smoking Cessation and the Effect on Diabetic Hgb A1c Levels The purpose of the presentation is to identify if smoking cessation results in lower Hgb A1c levels for diabetic patients who are active smokers and to use this information to further promote the benefits of smoking cessation. The use of the Hgb A1c is considered a standard of care for evaluation of diabetic management and glycemic control. Having an association of lower Hgb A1c levels with smoking cessation may encourage more patients to consider this lifestyle modification. A review of literature was conducted and found a correlation between smoking and insulin resistance and lower Hgb A1c levels with nonsmoking diabetic patients. Smoking cessation is a lifestyle modification that can improve glycemic control, reduce risk factors for microvascular and macrovascular complications, and reduce overall mortality in diabetic patients. Best practice of diabetic management should include smoking cessation counseling and pharmacological therapy for all diabetic patients who smoke. Evaluation of smoking cessation for diabetic management should include frequent scheduled follow-up with healthcare providers, continued reinforcement of smoking cessation, and obtaining Hgb A1c levels as recommended.

The styles are Beowulf, Arthurian Romances, and The Canterbury Tales. This story is one of my originals, along with all of the characters, names, and places. This is just an example of how different styles of literature are all able to be used to diversify stories, and improve each other. Brandstein, Sarah William Joffroy Faculty mentor: Melissa Santana, College of Arts and Letters (CAL) As of 4-19-13 UG Symposium Presentation Abstracts Community Building through Design The Rabbi of the Chabad Jewish Community Center of Flagstaff asked NAU’s Interior Design II class to come up with a design for the youth section of the community center. This project involved a few steps of the design process, of which each pair of interior design students applied to come up with one final solution. We interviewed the client, measured the space, produced preliminary sketches, floorplans, and material selections, finalized all decisions on floorplans and materials, created an eye-catching presentation board, and finally presented our designs to the Rabbi. The youth section of the community center was desired to be a comfortable place for anyone from young children to young adults to come and relax, socialize with peers, work on homework and play games, while also having the flexibility of becoming an overflow space for services and events that include plenty of food and need a lot of space to watch projection films. My design partner and I did research to gather information about the Jewish heritage and the community center to develop a design that abided by our design challenges, which included using the community center’s existing furniture, structural materials, and fluorescent lighting, as well as employing human ergonomics to work with the spacial requirements of billiards tables. Additionally, my and my partner’s goal was to create a space that correlated with the Jewish Community Center’s mission statement, “We create a warm, welcoming environment for everyone to explore and experience our heritage in a non-judgmental and inviting atmosphere.” Brent, Steven Faculty mentor: Dean Smith, Franke College of Business (FCB) Market Solutions for Municipal Water Pricing Different market valuation methods will be analyzed to determine what system is the best choice for municipalities. Brown, Aniza Maria Espinola-Romero Faculty mentor: Sheryl Howard, College of Engineering, Forestry and Natural Sciences (CEFNS) LDPC-Encoded System With Min-Sum Decoding Low density parity check (LDPC) codes can provide state-of-the-art error correction, and are used for many applications, including deep-space communication and satellite video broadcasting. LDPCs are easily decoded using a graph-based decoding algorithm, such as the min-sum algorithm. Probabilistic log-domain messages are passed back and forth between the two portions of the graph-based decoder, which are the bit nodes and the check nodes. At each bit node, the decoder sums incoming messages together, while the check nodes output the minimum magnitude message from their connected bit nodes. An ongoing research project at NAU simulates a communications system using a short-length LDPC, a Gaussian noise channel and the min-sum decoder in VHDL. Use of finite-precision messages in implementation can result in a sum of zero at a bit node; a zero message is a problem in the decoder. These zero As of 4-19-13 UG Symposium Presentation Abstracts messages propagate through the check nodes until all messages are zero, and the resulting decoder output becomes arbitrary. This project seeks to convert any zero messages to non-zero messages with appropriate sign and small magnitude. This project has two parts. The first part corrects the zero messages in the min-sum decoder. The second part is to simulate the updated VHDL min-sum decoder on an Altera DE-2 board to determine the bit error rate of the LDPC-encoded system with min-sum decoding. Brown, Monique Nashelly Meneses Faculty mentor: Nashelly Meneses, Russell Benford, Stephen Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) Factors Affecting Nesting Beach Selection of Green Sea Turtles in Saipan Green sea turtles (Chelonia mydas) are a keystone species in marine ecosystems. However, the population has been declining for decades. Previous research has shown that human impact, beach width and length, sand characteristics, and slope significantly affect nest selection. Factors such as these are not known in the Mariana Islands, a key migration point for green sea turtles in Japan and the Philippines. To determine which factors affect nesting beach selection on Saipan, I characterized human impact, vegetation, substrate, site accessibility, beach width, and predation levels on nesting and non-nesting beaches. Of the six factors that I investigated, human impact, evaluated by visitor counts (N = 16; t = 2.79; p = 0.009) and vehicles present at the beach (N = 16; t = 2.87; p = 0.006), and species richness of dune vegetation (N = 16; t = -2.22; p = 0.02) showed the greatest effect on nesting beach selection. Nesting beaches are characterized by lower human impact and a higher species richness of vegetation. Focusing on these factors in future management programs could relieve environmental pressures on the species and assist in their recovery. Brunskill!, Matt Faculty mentor: Anne Scott, Honors Program Roidball Roidball is a proposition to create a separate sporting league in which all players are using anabolic androgenic steroids.

The metabolic engineering of known and de novo biosynthetic pathways has potential to mitigate environmental and health risks posed by many current industrial synthetic practices through mild bio-catalyzed reactions and benign starting materials. A de novo metabolic pathway was employed to create catecholate derived precursors of adipic acid, one of the primary feedstocks in the polymerization of nylon 6,6. Cis,cis-muconic acid was produced using a multiple-mono cistronic plasmid construct in an Escherichia coli heterologous host. Purification of cis,cis-muconic acid was accomplished using ion exchange chromatography and acid precipitation reactions. Purified products were characterized with mass spectrometry and thin layer chromatography. Buchanan, Cody Faculty mentor: Kevin Ordean, College of Engineering, Forestry and Natural Sciences (CEFNS) Flagstaff Compost Co. I will be presenting on a composting business startup company I have been working on for my internship under Kevin Ordean with the NAU Green fund. We have developed a business model for a compost company to start up in Northern Arizona and have secured $5,000 in funding with an additional $7,000-$10,000 pending. Our process and model are simple: first we charge local businesses a pick up fee for raw compost materials, second we convert raw compost materials into a rich product that aides in plant growth, and third we then sell that rich compost material in bulk and bags to local consumers who are demanding a compost product.

This could negatively impact nutrient cycling because of their role as detritivores. However, on Saipan, the decline in the population of an introduced invasive gastropod, the giant African land snail (Achatina fulica), has lead to an increase in gastropod shells available for hermit crab use. To test whether the increased shell As of 4-19-13 UG Symposium Presentation Abstracts availability has had a positive influence on the hermit crab population, I surveyed hermit crabs at six locations on the island. I recorded size, shell type, and species of each crab found. I evaluated how shell size varies among locations and how it varies among location types (beach and inland,) using a Wilcoxon test. Shell size varied among locations (N=257, X2=154.19, P<0.001) and shells found at inland sites were larger than those found at beach sites (N=6, X2=54.25, P=<0.001). Native hermit crab species can benefit from the decline in the invasive giant African land snail. Burns, Genevieve Faculty mentor: , Honors Program Land of the Morning Calm See South Korea through the eyes of an exchange student! “Land of the Morning Calm” is a reflection of my semester studying abroad at Keimyung University in Daegu, South Korea. Daily life, university life, and the trials and tribulations of being a study abroad student were all recorded for my own reflection—but such experiences are meant to be shared. Important aspects of my life were my exposure to Korean Buddhism, friendships with Koreans and other exchange students, and the general Korean way of life, but being an exchange student is about so much more. My experience also included trips to the other major cities, and to industrial and cultural sites around South Korea. Studying abroad is a life-changing experience that I now know and love and I encourage everyone to pursue different educational opportunities or travel experiences wherever they are in life. Burris, Codi Faculty mentor: George Gumerman, Honors Program Fighting the Diabetes Epidemic Among the Navajo People It appears as though the American food system has done society a great deal of good by making food really inexpensive and in large amounts. But, this type of food system is not good for many ethnic minorities. The majority of the lower class is composed of ethnic minorities; they will be able to afford food, but not the most nutritious and healthy foods. As a result, there are numerous health diseases among this specific type of Americans. The real problem is that the majority of those diseases can be prevented by consuming more nutrient dense whole foods and being more active. The lack of education and the scarce amounts of healthier foods available to these minorities needs to be reformed. An example of where a minority group has adapted to the American food system and has fallen victim to health concerns is the Navajo people and their long struggle with diabetes. It is no question that Diabetes prevention programs and events should be more culturally appropriate and open for the community to participate in. The programs need to be aware of the history of the Navajos with Western foods, the culture's staple foods, and techniques to connect traditional knowledge with the contemporary. By analyzing the prevention programs and events targeted towards Navajos, we may be able to improve their effectiveness and help the rest of America as well.

Recent empirical research shows that the majority of rapes are done by an acquaintance or someone the survivor knew. Recent studies also show that the majority of perpetrators were intoxicated during the sexual violent crime. The increase in acquaintance rape involving alcohol has caused scholars to look at possible causes of this increase. Scholars like Jackson Katz relate the media perception of what it means to be masculine is highly related to the increase of alcohol related acquaintance rape. Possible solutions would be to change sexual violence prevention education towards developing safe relationships, knowing a bad relationship, and how to prevent yourself or someone else from committing the crime. Buttacavoli, Dean Faculty mentor: Peggy Pollak, College of Engineering, Forestry and Natural Sciences (CEFNS) KARES Educational Youth Garden Since the advent of the Green Revolution in the late 1950’s and early 1960’s, the industrial food system has been deteriorating the health and prosperity of the American public and the environment with its frequent use of nitrogen-based fertilizers, toxic chemical pesticides, and carbon emitting farm machinery. More specifically, the adverse effects of an industrialized food system have severely affected the health of American children. Today, the onset of diet related illnesses among children steadily climbs past levels that are unprecedented. In an effort to educate children about the importance of healthy and sustainable eating, Friends of Flagstaff’s Future (F3) established its Kids, Art, Reading, and Eating for Sustainability (KARES) program. Looking to advance the program’s initial efforts, we established a KARES educational garden space where children will have the opportunity to maintain an organic vegetable garden. Through engaging young students in basic sustainable gardening practices, F3 hopes to get more children interested in growing and eating healthy, organic food. By educating the city’s youth on the importance of sustainable and local eating, the program will cultivate a food ethic within these young students that will quietly yield political change as these students consistently choose to support healthy food products and environmentally responsible companies. By essentially voting with their food dollars, these students will be empowered to move the market with their new consumer demand for healthy and sustainably grown foods.

This report begins with a brief history of prostitution throughout the world, as well as brief description of legal cases pertaining to the subject. The presentation then delves into research on the pros and cons of legalizing prostitution in the United States. Pros discussed include: full rights to the human body, freedom of choice, economic growth, decreased unemployment, and decreased crime. The con focused on in the presentation is the moral backlash that would arise as a result of legalization. In addition to the pros and cons of legalizing prostitution, this presentation also details the regulations needed to safely and effectively legalize prostitution in America.

Caniglia, Patrick Faculty mentor: Andrew Koppisch, College of Engineering, Forestry and Natural Sciences (CEFNS) Studies on the effect of 2-C-methyl-D-erythritol supplementation on algal and bacterial cultures Plants, bacteria and green algae all use the Methyl Erythritol Phosphate (MEP) Pathway to synthesize isoprenoids, which are vital for the survival of all forms of life. Dephosphorylated methyl erythritol (ME) was supplemented to Botryococcus braunii green algae colonies to test if they take in the ME as a precursor to their isoprenoid synthesis. This supplementation showed a change in the overall health of the algae itself, as well as exponential increase in the population of symbiotic bacterial cultures present with the algae. Further supplementation of ME to reproduce these results with individual bacterial colonies have shown little difference in growth when given and restricted ME in nutrient minimal media. While ME was capable of exerting physical modifications to B. braunii cultures, our results suggest this modification is not a result of the bacteria consuming the ME. Canterbury, Sean As of 4-19-13 UG Symposium Presentation Abstracts Faculty mentor: Paul Gazda, College of Engineering, Forestry and Natural Sciences (CEFNS) Sustainable Landscape Maintenance Project My internship was with the Sustainable Landscape Maintenance Project, which is a student Green Fund project at Northern Arizona University. The goal of the project was to reduce and eventually eliminate the use of toxic herbicides on campus grounds. I, along with two other interns and the project leader, worked from May until November of 2012 documenting weeds on selected plots. There were three project sites, each consisting of a control plot and a test plot. The control plot was managed by the grounds department and had regular herbicide treatment. The test plots were managed by the project team and had no herbicide application. The weeds on these sites were eliminated by manual labor, being either pulled up or dug up. The main problem weeds that were encountered consisted of dandelion, plantain, clover, and black medic. It was found that weed abundances were generally higher on the lawns, which weren’t sprayed with herbicides. However, the grass on the test plots did appear to be much healthier than the control plots. It was shown that it is possible to go herbicide free however there does need to be a level of tolerance when it comes to weed presence. More experimentation would need to be done to determine if the NAU grounds department has the capability of implementing such practices in the near future.

Carranco, Jackson Hill, Aryel & Laws, Terry Faculty mentor: Matthew Anderson, Jason Whetten, College of Social and Behavioral Sciences (SBS) Dont Stress it, Sweat it! In order to determine if exercise reduces perceived stress levels, we constructed a study in which we provided an in-class survey for undergraduate students between the ages of 18 and 50 enrolled in a section of Research Methods in Psychology at Northern Arizona University. This topic is very intriguing because many students deal with high stress levels on a daily basis and are interested in coping mechanisms. Also, this topic should interest students because many want to spend free time exercising but feel it is something that they cannot justify affording time for. Upon conducting our research we expect to find negative correlations between the amount of As of 4-19-13 UG Symposium Presentation Abstracts exercise one typically engages in and the average perceived stress levels they experience and between the intensity of their exercises and perceived stress. We also expect to find a stronger negative correlation between aerobic exercises and perceived stress (as opposed to strength training, yoga, and sports). We will be using one t-test to test the relationship between the yes/no close-ended question ("Do you exercise regularly?") and perceived stress, two product-moment correlations to test the correlations between duration and intensity and perceived stress, and one ANOVA to test which type of exercise (if any) is correlated to having the lowest levels of perceived stress. Past research on this subject performed by different researchers concluded that exercise does reduce perceived stress. We are predicting that exercise does indeed reduce perceived levels of stress, as other studies suggest; however, we are also attempting to produce more information as to which variables (duration, type, and intensity) have the strongest effect in determining reduction of perceived stress levels among those who do regularly exercise. Carroll, Katherine Margo Dufek, Andrew McCarthy, Leanne Willey Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Harnessing Wind Energy From Recycled Materials The goal of this project is to provide inexpensive electricity to citizens of third world countries who have limited access to electricity. The scope of this goal is to design an inexpensive, portable wind turbine system to harness wind energy and supply enough energy to power a light and a fan (approximately 100W combined) for five hours per day. The wind turbine system will include both a wind turbine to generate electricity, and a means of storing the electricity generated. The constraints include a maximum budget of $50, maximum weight of 100 lbs, and a minimum of 0.5 kWh generated and stored per day. The final design will be made from recycled and scrapped materials, including blades cut from PVC piping, a shaft from an evaporative cooler, a recycled generator, scrap lumber and sheet metal, and a car battery to store electricity. The turbine will be five feet in diameter, and is designed to be mounted either on the roof or side of a house, or on a wooden post sunk into the ground. The prototype is meant to serve as an example to show individuals in remote locations how to create their own wind turbines, based on the materials they can salvage.

Evidence provided by organizations, like the CDC, show that the statistics of TDV are still high within the U.S. Despite domestic and sexual violence coalitions and community-based efforts, schools and students are not benefitting fully from TDV programs. Caudill, Blaise Faculty mentor: Robyn Martin, College of Social and Behavioral Sciences (SBS), Honors Program Exploding the Collective Structural Imaginarium: The Black Widows of Chechnya as Actors on the International Stage The myths of polarized dichotomies that prohibit women from behaving in a violent, aggressive and outwardly powerful manner are decimated by women taking assertive roles in violent terrorist events-- such as the taking of over 200 hostages at Moscow’s Dubrovka Theatre in 2002 and the 2004 hostage situation at the Beslan school in Northern Ossetia, in which more than 300 individuals (including school children) lost their lives. The women involved in these terrorist acts, labeled the Black Widows by western press, are the only women to have dawned the ominous ‘suicide belt’ (Banner 2009:1) and have participated in “every terrorist attack launched by Chechens against Russia” (Nivat 2005:419 cited in Banner 2009:1). Underneath the obvious questions of why this group turned to terrorist acts begs the question: why were women the vital actors within these acts? This study will defend that the extent to which women were (and continue to be) involved within the Black Widow movement is directly related to the collective imagination of societal structures in which they were and are forced to obey. Cavin, Langston Faculty mentor: Jason Wilder, College of Engineering, Forestry and Natural Sciences (CEFNS) Examining the Frequency of a Neanderthal-Introgressed Variant of STAT2 Across a Linguistic Contact Zone in North Maluku Indonesia The islands of North Maluku, Indonesia occupy a central position in the major prehistoric dispersal streams that shaped the peoples of Island Southeast Asia and the Pacific. Within this region a linguistic contact zone exists where speakers of Papuan and Austronesian languages reside in close proximity. A haplotype, known as the N haplotype, is carried by many Eurasians and shares close sequence similarity as well as a recent common ancestor with the Neanderthal sequence. The N haplotype is found at a ~10-fold higher frequency in Melanesian populations (~54%) compared to Eurasian populations (~5%). Here the frequency of the N variant of STAT2 is examined across North Maluku, a contact zone between Melanesian and Eurasian populations.

Poma lifts are designed for skiers so that a small round disk sits between their legs and they are able to lean back and be towed up the mountain. This presents a problem for snowboarders whose riding orientation is perpendicular to that of skiers forcing snowboarders to hold onto the pole with just their arms while riding the Poma. To remedy this problem, a new design has been created that maintains most of the functionality and dynamic systems of the old Poma lift while providing equal comfort and support for both skiers and snowboarders of varying body types. A new outer pole has been created that has been reoriented into a flattened “U” shape so that there is back and hip support for riders of any orientation. There is a plate located on the newly designed outer pole that better supports skier’s backs and snowboarder’s hips. A current Poma lift pole has been disassembled to allow the inner dynamic spring assembly to be removed. This inner spring assembly allows the pole to change heights for different sized riders and varying terrain. This will be maintained in the new design. The new design will be prototyped and tested for practicality at Elk Ridge Ski Area. The long term goal is to replace at least half of the Poma poles on the mountain which should increase sales because snowboarders will feel more comfortable using the lift.

ISIS uses hundreds of command line tools to manipulate these satellite images for use in research. While a useful and powerful tool, ISIS requires users to write their own scripts to use multiple tools in succession, which is a skill most new users of ISIS do not possess. This lack of a user-friendly interface makes it difficult for scientists to use without a lengthy training process and causing frustration for its users. Our solution to this problem is to integrate ISIS with Galaxy, a workflow processing tool. Galaxy allows users to easily use tools in succession by creating a workflow via a graphical user interface. Instead of writing scripts, users simply need to click, drag, and specify parameters as necessary for each tool. The use of this graphical user interface will lead to a reduction in training time and provide an easier means for scientists at the USGS to interact with ISIS.

Their operations require a moderate and consistent supply of power which is currently being purchased from local power companies at high costs. Supreme Manufacturing approached our design team for an alternate power source that can reduce their energy costs, as well as their carbon footprint. After rigorous analysis, we concluded that combined heat and power (CHP) from a natural gas system can be successfully implemented in this application. To prove the concept, we designed a 1/10th scale prototype CHP system that can generate 3kW of electrical energy along with sufficient amount of heat to maintain a scaled oven at a temperature between 93-105o C. To achieve higher efficiencies, we designed a Heat Recovery System (HRS) based on a concentric, cross-flow heat exchanger. The HRS exchanges heat with the inner exhaust duct via forced convection from a centrifugal blower to heat the scaled oven. Integrated into the CHP is a temperature sensor network, a valve assembly and control switches that are all autonomously maintained through our microcontroller-based Control As of 4-19-13 UG Symposium Presentation Abstracts System.

The responses of native herpetofauna to forest management treatments designed to reduce the probability of wildfire in northern Arizona is currently unknown. In this study we are comparing herpetofauna activity in mechanically thinned stands to activity in adjacent unthinned stands by conducting fixed-time and fixed-area surveys over seven months. We are also constructing slash piles within each stand to measure their selective use by herpetofauna over the same period. We expect reptiles to occur more frequently in warmer thinned stands due to their reliance on environmental energy to produce and maintain body heat. Alternatively, amphibians require humid environments; therefore, we expect them to occur more frequently in unthinned stands. Further, we expect that herpetofauna use of slash piles will interact with stand treatment type. We hypothesize that reptiles and amphibians will utilize slash piles more frequently in stands they are found inhabiting. However, we also expect slash piles to provide suitable habitat for migrating amphibians. Therefore we may observe no difference in amphibian usage of slash piles among both types of stands. This study will document previously unknown patterns of herpetofauna behavior and distribution in management-altered environments in the southwestern region of the U.S. Clawson, Bret Rebecca E.

Faculty mentor: David Wagner, College of Engineering, Forestry and Natural Sciences (CEFNS) Identifying flea species associated with early phase transmission of plague Yersinia pestis, the pathogenic bacterium that causes plague, survives exclusively within a cycle of fleas and mammals. The traditional model of plague transmission involves rapid esophageal blockage in the flea, leading to increased feeding rates and regurgitation of contaminated blood that infects new hosts. However, many North American flea species can transmit plague long before blockage occurs, in a process known as early phase transmission (EPT). EPT is thought to result from plague bacteria that reside in mouthparts, rather than the esophagus. In a 2001 plague outbreak in Flagstaff, AZ, individual fleas of unknown species were found to carry a wide range of Y. pestis loads, ranging from low (EPT model) to very high (blockage model). In the current study, we are identifying each of these fleas to the species level by sequencing a 700 bp region of the cytochrome oxidase II (COII) gene from the mitochondrial genome. This widely used barcoding gene contains many species-specific mutations that allow us to unambiguously identify North American fleas found on prairie dog colonies, including Oropsylla hirsuta, O. As of 4-19-13 UG Symposium Presentation Abstracts tuberculata, and Pulex simulans. Using our species-level information from the 2001 fleas, we will compare differences in Y. pestis load among flea taxa and determine which species, if any, are more important for EPT versus blockage transmission. These data will strengthen our understanding of plague transmission in North American ecosystems. Cleland, Jessica Faculty mentor: Abbe King, College of Health and Human Services (CHHS) An Assessment of Pre-operative Skin Preparations: Recommended Practice One of the most significant risk factors associated with invasive surgical procedures is the development of surgical site infections. According to the Association of Perioperative Registered Nurses (AORN), the current recommended practice for prevention of surgical site infections includes two preoperative showers with chlorhexidine gluconate solution, in addition to the operative site being cleansed immediately prior to the start of the procedure with either an alcohol-based or iodine-based skin preparation. After comparing the current practice standard at Flagstaff Medical Center for preoperative skin preparation in adult patients receiving total hip or knee arthroplasty with the standard recommended by the AORN, it is determined that Flagstaff Medical Center maintains current policy standards. In addition, after compiling and analyzing literature from a variety of studies, it is determined that the use of chlorhexidine-alcohol is associated with fewer infections within the superficial incision at the surgical site.

The project’s effectiveness is determined by comparing the class discussion and written results of assignments completed by students in a first year CAD class at Northern Arizona University (NAU) to the class discussion responses from a second year drafting class at Xi’an University of Science and Technology (XUST) in Xi’an, China. This comparison will help determine if first year CAD students are prepared to learn GD&T or if another year of engineering design is necessary for them to understand the subject. The materials presented at both universities were developed based on a literature review of publications on implementing GD&T into an engineering degree program and a research survey of other American universities currently teaching tolerancing in their engineering graphics courses. The university survey was limited to universities similar to NAU offering only a Bachelor’s and Master’s degree in Mechanical Engineering. From the literature review, a hands-on teaching method was selected involving the use of physical models manufactured from SolidWorks drawings toleranced using the ASME Y14.5 standard. The university survey allowed researchers to obtain syllabi and schedules from other engineering graphics courses, and from these determine what topics of GD&T to present and at what point in the current curriculum to implement them. The final materials developed include a lecture and As of 4-19-13 UG Symposium Presentation Abstracts several homework problems. The lecture covers why GD&T is important, how to develop a datum reference frame, and how to select material condition modifiers. A student survey will be conducted to determine opinions of the materials presented. This survey and homework, along with the class discussions from both universities, will be used to determine if design background knowledge in engineering is required before introducing GD&T to students. Cody, Jennifer Faculty mentor: Karna Otten, College of Engineering, Forestry and Natural Sciences (CEFNS) Community Supported Agriculture: The Need for More Public Exposure The objective for my internship at the Flagstaff CSA was to promote the CSA’s efforts to reach more of the city’s consumers. In order for this non-profit to continue to grow and serve the public, more seasonal shares have to sell. I achieved this objective by enhancing the market portion of the website, contacting vendors to tell me about their products for Facebook promotion, updating the social networking sites, canvassing local businesses, education, filling in a map at the market with the locations of major vendors, and organizing a cleanup day in the surrounding neighborhood. The public has been very responsive to my efforts to promote the CSA, especially on the social networking sites. My efforts have brought new people to the CSA, who had previously only heard of a CSA, and have made the public more aware of the products that are carried at the CSA market. Coiro, Taylor Jessica Gaddy Faculty mentor: Laura Crouch, College of Health and Human Services (CHHS) NPO after Midnight: An outdated Practice The practice of “NPO after midnight” or nothing by mouth has long been maintained in the hospital setting. This practice involves no food or liquids after midnight the day of surgery. This is done in order to decrease the amount of gastric contents therefore lowering the risk of aspiration during surgery. This brought forth the question: for hospitalized healthy adult patients, does the use of NPO (nothing by mouth) after midnight reduce the future risk of aspiration during surgery compared with allowing clear fluids two hours before surgery? Through our review of the current research, it was found that the practice of “NPO after midnight” is outdated and unnecessary. The focused population was hospitalized healthy adult patients. Healthy is defined as those without diabetes, hiatal hernia, obesity and gastroesophageal reflux, ileus or bowel obstruction, emergency care, pregnancy, or enteral tube feedings. There is no significant difference between the amount of gastric contents between a patient who fasts after midnight, and those who ingest clear fluids up to two hours before surgery. Even with the current findings these guidelines are not implemented into practice, and many patients abstain from both solids and liquids for far longer than necessary. Patients should be placed NPO according to their surgery time, individual needs, and the American Society of Anesthesiologists guidelines. It is recommended that hospital staff be further educated on the current guidelines of preoperative fasting, so that care can be patient-centered, and thereby improve the outcomes of patients pre and postoperatively.

In the United States, "obesity" is perceived as a problem by many in the medical field and the general public. Contrary to popular opinion, "obesity" has many complex causes and consequences, some of which are social and others biological. High fructose corn syrup has been identified as a major contributor to a rise in "obesity" in the United States, as it is put in almost all conventional foods. What are the relationships of corn products to weight status in the US and how do they relate to our measure of body mass index (BMI) and percentage body fat (PBF)? There is growing evidence that the latter may be a more accurate indicator of weight status, but BMI is currently the most widely used method. We will be using a mass spectrometer to analyze the stable carbon and nitrogen isotopes of the hair samples, and use questionnaires to illicit specific information about the diet of participants. We expect to find a positive correlation between the stable isotope values indicative of corn in hair and the measured PBF and BMI of the participants. If our expectations are founded, this could greatly influence future methods of assessing diet and weight status, and call for a reassessment of subsidy policies pertaining to corn.

Northern Arizona University has been a leader in promoting diversity, not only among students, but also within its curriculum. Fostering awareness and understanding about the diversity of the world is one of the main goals that NAU has set for its students. One way this is being done is through the undergraduate minor in Disability Studies. This minor is offered to any undergraduate student and introduces a way to think critically about disability. Disability Studies challenges students to examine their perceptions about disability and promotes a realistic view of disability within social, cultural and political contexts. Students critically assess their views on disability and examine society’s views on people with disabilities (PWD). In doing so students are able to gain an understanding of the impact society has on people with disability, while developing a view of PWDs within a minority model that reflects and honors their collective voice. Our poster presentation will explore our collective growth in understanding disability as diversity and how understanding disability issues has influenced each of us in our major areas of study. In addition we hope to raise awareness about the minor in Disability Studies on campus.

Accessible databases were searched for articles investigating the efficacy of Music Therapy. Only “databased” articles obtained in this search were reviewed (summary articles, case studies, and anecdotal studies were not included) according to the 21 quality indicators outlined by Horner, et al (2005) for Single Subject Design studies. The search resulted in 22 articles being identified as “data-based” and specifically related to Music Therapy and ASD. Only 11 of these articles could be scored for quality indicators of good science with 100% of these articles scored by two independent reviewers. The two independent reviewers scored these data-based articles and those scores were compiled into a database and compared. Scores of the 11 articles were compared and tested for reliability, then labeled as “acceptable” if the article included between 17 - 21 quality indicators or “not acceptable” if the article included 16 or fewer quality indicators. All 11 articles testing Music Therapy with individuals with ASD were found to be “acceptable” articles, according to the Horner, et al guidelines. Quality Indicators and other criteria can lead to establishing interventions as evidence-based practices. These results suggest that there may be some emerging empirical support for Music Therapy for individuals with ASD. However, issues in diverse methodologies and similar dependent variables need to be addressed in future research. Compton, Daniel Zane Morgan, Crystal Olivarez Faculty mentor: Dierdra Bycura, Hendrik deHeer, College of Health and Human Services (CHHS) Dartfish analysis of de-weighted running on an Alter G treadmill from a side view The Alter G antigravity treadmill is a treadmill that can de-weight a person up to 10% of their body weight decreasing gravity’s effects on the lower body joints. With regard to injury, disease, or severe obesity, weight could be a factor in properly exercising. For this reason there is a need to study the effects of gravity on the biomechanics of running. The purpose of this pilot study was to determine which biomechanical gait factors could be measured by observing persons running at different percentages of body weight on an Alter G treadmill using Dartfish computer software. Specifically we examined ankle angle from a side view at first contact point with the ground at three different body weight percentages. 1. What changes are observed when de-weighting a person on an Alter G treadmill? 2. Did using different running protocols affect ankle angle from a side view? 3. Did the de-weighting from the Alter G affect heel strikers more than toe strikers? We incorporated four participants in this pilot study with two protocols. Warm up: As of 4-19-13 UG Symposium Presentation Abstracts • 3 minute walk at 3.5 MPH 100% bodyweight • 3 minute jog at 5 MPH 100% bodyweight Protocol 1 • 3 minute jog at 70% HRR 100% bodyweight • 3 minute jog at 70% HRR 70% bodyweight • 3 minute jog at 70% HRR 40% bodyweight Protocol 2 • 3 minute jog at 70% HRR 40% bodyweight • 3 minute jog at 70% HRR 70% bodyweight • 3 minute jog at 70% HRR 100% bodyweight Results indicated that all participants experienced changes in ankle angle and heel to toe striking in both protocols. In this pilot study we found as bodyweight decreased plantar flexion increased. We did not find much, if any difference between the two protocols. In addition, toe strikers experienced less change in ankle angle compared to heel strikers. Contreras, Karri Faculty mentor: Cynthia Pardo, Moran Henn, College of Engineering, Forestry and Natural Sciences (CEFNS) Friends of Flagstaff's Future Internship This study seeks to explain the benefits of a non-profit organization that aspires to build a strong localized community. Issues such as city planning, community involvement and education are evaluated to show the benefits that such programs has on the community as a whole. Topics of sustainability are explored due to benefits in many aspects of a community such as a strong local economy. Based on internship experience it seems that a main factor that strengthens a community is collaboration between many different stakeholders. These collaborations create an environment with a more informed population regarding city planning issues and new legislations. In addition these collaborations allow local businesses to work together to increase their success. This success creates a stronger economy, which in turn can support increased funding to important areas like education, and additional job creation. Education ties this all together by creating a community that understands the importance of sustainability, and showing people how it benefits them directly. Contreras, Karri Emily Gaddo, Rob Helmkamp, Elliot Hosch Faculty mentor: Diana Elder, College of Engineering, Forestry and Natural Sciences (CEFNS) The Use of Road Salts on Roads in Northern Arizona Salt is the quickest and cheapest method for deicing roads during a storm; however there are many negative environmental aspects associated with it. The leaching of road salts into local water tables, rivers, and streams can have a detrimental effect on local fish, amphibians, and countless other wildlife species. Long-term introduction of chloride into natural water supplies harms the development stages of fish species and become so acidic that fish and amphibian species cannot survive. Research shows that nearly 70 percent of road salts used end up in local As of 4-19-13 UG Symposium Presentation Abstracts water tables. Concentrations of sodium have also been proven to cause harmful effects on vegetation. The soils and vegetation alongside roads that are applied with the salt application have shown permanent soil alternations, which in return cause damages to the root systems, which causes dehydration and decay in the vegetation. Using ice on roads additionally has negative consequences for vehicles. Due to the presence of Magnesium Chloride, accumulation occurs, which causes premature deterioration of a variety of car parts including breaks. Some of the most popular alternatives to using salt on roads are Calcium magnesium acetate and potassium acetate, but they have not had the chance to replace salt due to high cost. New technologies such as the volcanic mineral, Ecotraction are promising but require more research on their effectiveness on a large scale. Other alternatives are predominantly centered on the use of chlorides, so unfortunately there are limited options for relying on salts during storms. Cooper, Kaele Faculty mentor: Anne Scott, Adam Hoffman, Honors Program College's Tiring Venture This art piece is made up of thoughts of current college students on literature, reading, and thinking about these subjects. Many responded and gave good ideas on what to put into this piece. It is a collage of this subject, done with charcoals, pencil, and watercolor, on watercolor paper, a mixed media piece. I have taken these students’ ideas and looked up ideas of each piece that they have suggested, as images and will take those to create the piece. There are varied descriptions of this subject and the collage involves a piece from another artist, and other ideas such as stacks of books. Some of the responses that I have gotten were, “Literature: a very defined art form, Reading” and escape, a new perspective, Thinking: is intimate”, “Reading is knowledge, you can’t know anything if you don’t read about it…” “Literature and reading are either super boring…or very artful and meaning full while expressing something,” I will also be going over how I got the idea, what inspired me, I will involve the quotes from the students that I asked for an opinion on. I will also go over the aspect of surrealism and how it inspired my piece, and how these aspects are related to surrealism. I have tried and studied the aspects of surrealist art, and although hard to understand I decided my piece will incorporate different types of literature. It will not only be just surrealist influence. There will me mystery, fiction, nonfiction, fantasy, science fiction, autobiography, and biography. Coulombe, Mary Faculty mentor: Roderic Parnell, College of Engineering, Forestry and Natural Sciences (CEFNS) Makauwahi Cave Reserve Internship Hawaii`s largest limestone cave, the richest fossil site in the islands, and a uniquely preserved archaeological site, the 17 acre park was created by Paleoecologist David Burney and Lida Pigott Burney. Excavations have yielded a picture of the entire prehistoric landscape. Using the fossil record as a guide, the project’s main goal is to re-create a landscape in the region surrounding the site that the first Polynesians may have encountered when they arrived. Another recent goal of the project is to evaluate the use of African Spurred Sulcata Tortoises as a control for invasive As of 4-19-13 UG Symposium Presentation Abstracts weeds. Internship tasks included acting as a docent for the cave, assisting with behavioral sampling and controlled experiments for the tortoise project, coordinating a summer fun daycamp for the County Parks & Rec Department, and creating a promotional video for the website. The most important accomplishment of the internship was effectively using public outreach to gain support and raise awareness for the organization and the problems facing Hawaiian endangered species. Field data was provided for the ongoing tortoise experiment. The main significance of the internship was ensuring another summer of educational outreach with the County Parks & Rec school groups, and spreading the word of the organizations innovative restoration tools by posting an attractive video for the site.

Covington, Keanaloha Tiesha Douglas, Chris Connolly, Troy Kemp Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) More exercise means more sex drive! Sex and fitness are two popular topics in daily life today. They are linked together due to the possible way it can increase a person’s self-esteem and body satisfaction; therefore it is important to realize the positive correlation between sex drive and exercise. In addition, there is not enough information on sex drive and how exercise effect’s it. Previous research suggests the differentiation between male and female sex drive (specifically, in the areas of male and female hormone levels as well as the frequency of exercise). In this study two participant samples were used. One was composed of 100 volunteers in the Recreational Center and the other was made up of 100 students in the Research Methods classes. Asking participants how often and how long they engage in physical activities assessed the measure of exercise. They also answer questions relating to their current or past relationships and how they would measure their sex drive levels on a regular basis. Based on the research results between sex drive and exercise, there was a positive correlation is hypothesized. In other words, the more a person exercises, the higher levels of sex drive they will have. Furthermore, it is predicted that there is no difference in sex drive between men and women. If these findings are supported, one should exercise if they want to achieve a higher sex drive.

Creager, Erica Amanda (Sal) Webber Faculty mentor: Corina M. Kellner, College of Social and Behavioral Sciences (SBS) Stable Isotopic Evidence of Ancient Globalization in the Cotahuasi Valley of Peru The Middle Horizon (AD 500-1000) period was a time of great change in Peru. The influence of the Wari Empire was felt throughout Peru, even in areas that the Wari likely never came into contact with, such as the Cotahuasi Valley in the central highlands. This indirect influence provides an example of ancient globalization. Understanding the impact that the social and economic changes of the Middle Horizon had on the people in the Cotahuasi Valley helps us to understand how the actions of modern dominant cultures can affect others even without directly contacting them. Analysis of human tooth enamel from individuals buried at Cotahuasi provides us with carbon and oxygen stable isotopic values. Carbon stable isotope values in enamel are correlated with the type of diet consumed in childhood, while oxygen stable isotope values are an indicator of your water source and possible migration. The oxygen results suggest the migration of individuals into the Cotahuasi Valley and the carbon values may indicate differential access of food within our tested population. Migration and social stratification due to differential access to food may have happened in the Cotahuasi Valley because of the dramatic social and economic changes of the Middle Horizon. Evidence of this influence already exists in the architecture, funerary practices, and ceramics of Cotahuasi. Our results support the conclusion that through globalization, the Wari Empire and the Middle Horizon impacted the life and culture of the people in the Cotahuasi Valley. Credo, Jonathan Faculty mentor: Jani Ingram, College of Engineering, Forestry and Natural Sciences (CEFNS) Detecting a Subtle Toxin: Assessing Arsenic Levels in Unregulated Wells on the Navajo Reservation Arsenic is a naturally occurring toxin and carcinogen found in many water supplies around the United States. The western United States naturally has higher levels of arsenic in the water due to the specific geology of the area. Because of this fact, unregulated wells may contain levels of arsenic that exceed the EPA’s limit of 10 ppb. This research sought to determine the total arsenic concentration in a number of unregulated wells, still in use, on Navajo Reservation lands north of Flagstaff, Arizona. At present, there exists little to no quantitative information surrounding arsenic contamination in water supplies for this region. As of 4-19-13 UG Symposium Presentation Abstracts Due to the low concentrations expected in the water, all samples were analyzed via inductively coupled plasma mass spectrometry (ICP-MS) which allowed for accurate detection of arsenic in concentrations less than or equal to 0.5 ppb. Prior to analysis, examination of arsenic with the ICP-MS had to be validated due to spectral interference from Ar40Cl35 species. Application of correction equations, which calculate the interference from Ar40Cl35 and compare it to As75, was found to be a valid way to address any spectral interference issues. To ensure reproducibility, samples were run in duplicates. A number of sites were determined to exceed the EPA’s legal drinking limit, some approaching concentrations of 50 ppb. Water analysis from the Southwest Navajo Nation will be discussed. With this knowledge, communities can be alerted to which wells exceed this limit and create action plans to mitigate exposure. We acknowledge NIH for supporting this work. Crockett, Amy Faculty mentor: Melissa Santana, College of Arts and Letters (CAL) Engaging and Reviving a Community: The Development of a Sustainable Community Center in Winslow, AZ The main focus of this project was to create a community education center for residents to find their sense of place and their love for Winslow. The community center idea results in more community involvement, and positive contributions. Sustainability and positive land values are the roots by which the Winslow Community Center is grounded. Natural materials, biomimicry, and new technologies are all interwoven into the design of the space to create the harmony that Winslow seeks. Traditional Native American architecture and values have been taken into consideration and by creating a balance between new and old within the interior, it helps to represent the evolving cultures of Natives in the community. Natural, low impact materials, earthy textures, and organic colors come together in harmony in order to create this balance. Lighting in the space is utilized as an important tool to create rhythm, proportions, and layering. The inherent shape of the building and interior is used as a tool to create rhythm as well. Overall, the Winslow Community Center is used as way to create a stronger awareness, and empower the residents to strive for personal and community wellbeing.

Cvach, Kelsey Faculty mentor: Meg Bleakley, College of Social and Behavioral Sciences (SBS) As of 4-19-13 UG Symposium Presentation Abstracts Causes of Egyptian Revolution My presentation will explore the origins and main actors of the 2010 revolutions in Egypt. Specific attention will be given to the role of religious organizations, diversity of civilians participating, and the political climate of the area during and preceding the protests. Of religious organizations, I will pay particular attention to the role of the Muslim Brotherhood and its social contributions to the climate leading to the revolutions as well as its direct role in getting activists into the streets. The Muslim Brotherhood, an 80 year-old organization has shaped political participation and even Egyptian identity throughout the decade preceding Mubarak’s ousting. I will next investigate the role of diversity in the Egyptian revolutions. The revolution was only successful because groups of all backgrounds and views participated. Though disputes would erupt afterwards, secularists, Christians and Muslims stood side by side in opposition to Mubarak’s regime. The uneducated working class were joined by young adults with university degrees. Additionally, the military’s refusal to quell protesters placed them in the eyes of many on the side of revolutionaries. I will also pay attention the political climate which rendered Mubarak’s regime illegitimate in the eyes of the Egyptian. Three factors were the basis of the political climate: recent widening of class inequality, the regime’s connection with the United States and the West, particularly the West, and the deteriorating relationship between the police and her civilians. The basis of each of these factors was corruption, which will be explored further in the presentation. Daley, Zachary Faculty mentor: Colonel Herman Brunke, Matthew Schmidt, College of Engineering, Forestry and Natural Sciences (CEFNS) Environmental Compliance at Nellis Air Force Base I performed my internship at Nellis Air Force Base where I affiliated myself with the 99th Environmental Squadron there and helped performed daily tasks for four weeks. The reason for this particular interest was to see if the military had different environmental views than the civilian world and whether I could perform these functions in my future career with them. I worked with many groups and performed annual inspections within the squadron. We went out daily to inspect building conditions and ensure standards were being followed along with state permits. This consisted of going to surrounding shops on base and inspecting hazardous materials and MSDS sheets. I filed paperwork after the inspections to document progress. I attended weekly meetings were taking place to allow for fluid communication between squadrons to keep up with current regulations. Having a flow of communication keeps everyone up to speed on current activities around base. Having this experience will allow me to understand these squadrons better and better utilize them when I am working on an active base. Compliance related work involves a lot of different people to accomplish one task within regulation. This was easily viewed throughout my internship here. One change to this experience would be to have been attached to one group within the squadron to be able to get more involved rather than changing between the groups. This will help future interns have more of a focus and be a part of the compliance work in an interesting field. As of 4-19-13 UG Symposium Presentation Abstracts Daniels, Kevin Melanie L.

Propper, College of Engineering, Forestry and Natural Sciences (CEFNS) Morphological and Behavioral Differences between a Fish Population from a Wastewater Effluent Pond Compared to a Reference Lake Globally, reclaimed wastewater effluent (WWE) is an important resource for irrigation, recreation, creation of wetlands, and direct recharge of aquifers. However, in the last decade many studies have found that exposure to WWE affects several aspects of endocrine function in aquatic vertebrates, including their behavior. To evaluate the effects of WWE on a local fish population, we compared several morphological traits in fathead minnow (Pimephales promelas) populations from a WWE pond to a nearby reference lake receiving no WWE. Fish from the WWE pond were significantly larger, had greater testes and ovarian weights (though not gonadosomatic indices), and were less active than fish from the reference pond. There were significant differences in the age structure of the two populations that may explain the morphological differences, with animals from the reference lake having significantly more juvenile fish. Reference lake fish had high tapeworm burden (100% of juveniles and 0% adults) that may contribute to the lack of adult fish in this population. WWE pond fish had brain cysts suggestive of a trematode infection. The finding of age structure and parasitic infection between these two bodies of water suggests that understanding the impact of exposure to WWE on populations of organisms needs to take into account more than the chemicals potentially released in the water system.

An additional objective of the internship was to help gain support for Mexican gray wolf reintroduction. The focus was on education of the general public in the importance of Mexican gray wolf reintroduction to the Grand Canyon area. This was achieved through a 400-mile relay hike from Alpine, Arizona to the South Rim of the Grand Canyon. Volunteers hiked sections of the trail, and were educated in wolf behavior, importance, and typical habitat. The author’s duties were: to organize volunteers by providing them with essential tools for hiking, to participate in the hike and educate volunteers, and to meet volunteers at the end of the section to drive them back to their cars. The author was also assigned paperwork and office tasks. By the end of the internship, the hike was halfway complete, and many volunteers were more educated in wolf reintroduction and its importance. The author learned about the difficulties of working for a non-profit organization. The main accomplishments of the internship were the completion of the relay hike and the spread of wolf information to volunteers.

Manual covers currently protect these mirrors; however, an automated cover is desired. The problem with the current system is that it requires staff to climb into the mirror housing to remove the manual mirror cover. The cramped conditions in the mirror housing have led to accidental damage of equipment and put the staff in danger, especially during the winter months when ice is an issue. Constraints for the automated cover include, it must not block any light from the mirror’s lens. The full range of motion of the mirror cell (siderostat) must be maintained after installation of the automated cover. The cover must be able to close in the event of a power failure. It also must maintain a nitrogen purge to blanket and protect the mirror surface. The final design is best described as a camera iris mechanism. This 30-inch iris with its 23 iris blades is mounted to the face of the mirror cell. The iris is actuated by a friction drive that is mounted at the top of the mirror cell. By rotating the top ring of the iris mechanism it actuates the blades to cover the mirrors surface. An orifice for the nitrogen is integrated into the irismounting ring to provide the inert environment the mirror requires.

Dempsay, Emily Michael Combrink Faculty mentor: Walter Vannette, College of Social and Behavioral Sciences (SBS) Who Owns Your Body? The Politics, Policies, and Implications of the Criminalization of Pregnancy Since the creation of the United States of America, equal human rights for everyone has been one of the founding principles. However, in the politics surrounding reproduction, the rights of the fetus are becoming more and more valued over those of the mother. This has resulted in the criminalization of pregnancy. The criminalization of pregnancy is a complex issue and through our research we have looked at the different aspects of it. First in this project we will examine the concept of "Who owns your body" and why that is important to our research. Next we will look at current policies concerning reproduction and what those policies imply for the care and As of 4-19-13 UG Symposium Presentation Abstracts treatment of women and infants. Following that we will use several case studies that illustrate just how strongly the policies are impacting women. Our research focuses mainly on events and policies within the US but we will briefly include cross-cultural comparisons. Finally we will provide suggestions for future policies and changes in current ones that reflect our research. DePaola, Taran Alex Velez, Dr. Woodruff Faculty mentor: C. Chad Woodruff, College of Social and Behavioral Sciences (SBS) Mirror Neurons and Muscle Tone This research project is focusing on the link between muscle movement and mirror neuron suppression. The goal is to look for a relationship between mirror neuron activity in conjunction with the observation of movement of certain muscles, specifically facial muscles. Presently, it is known that moving muscles in the face or any other area of the body can be detected on an EMG in regards to their respective bandwidths and electrical activity. The hypothesis is that "observing" the actions of another person will result in mu suppression of the same area of the brain responsible for one's own actions. An example: Viewing a person smiling should increase mirror neuron activity in the sensorimotor cortex region responsible for that same action as if the observers did the smiling themselves. Hypothetically it is not far-off to claim that observing actions will in return elicit a Mu response on an EMG. We believe that this research can be applied to educating those afflicted with Autism Spectrum Disorder. The actions that are observed would give a response in the brain, and the second part of the hypothesis would be whether or not "bold" actions would give a greater Mu suppression than their less-bold counterparts. In accordance with ASD, those who suffer from the disorder could receive better education by having their instructors teach with emphasis; that is, people with Autism might need stronger emotions to allow them to be able to understand those emotions better.

This study’s objective is to determine the behavior and interactions of host species that are most susceptible to rabies viral outbreaks and to investigate how urbanization affects outbreaks. Rabies is transmitted by infected saliva through a bite or wound. Rabies infects the central nervous system of mammals and results in brain damage and ultimately death. The host species that our study focuses on are foxes, skunks, raccoons, and bats. To establish host species interactions, we have trapped, radio collared, and are now tracking these species in designated urban areas in Northern Arizona. The radio collars that we use record when they come within a 5 foot radius of another collar. Through this, rabies host interactions are documented. We also manually radio track our collared animals and set up motion-activated cameras at their den sites. Our results since May 2012 have determined that frequent interactions between these host species are common and that many of these species share den sites. This study is still ongoing, but further insight into how host species interact could help to reform rabies management plans and prevent future outbreaks. Dillingham, Elise Kevin Daniels Faculty mentor: Scott Anderson, College of Engineering, Forestry and Natural Sciences (CEFNS) Implementing Bird Baths to Counteract the Effects of Reclaimed Water Consumption on Wildlife at Northern Arizona University Potable water resources are being depleted at an alarming rate worldwide. As an alternative to potable water, many countries, cities, and institutions have been implementing reclaimed water for many purposes, such as for irrigation. Within reclaimed water, organic compounds exist that are proving to be harmful to organisms and are having deleterious effects on natural environments. Many of these organic compounds are endocrine disruptors that affect several aspects of an animal’s endocrine system and their behavior. For these reasons, reclaimed water is not allowed for human consumption in the United States, yet there are no restrictions on the consumption of reclaimed water for wildlife. Due to this, it is crucial that we provide wildlife with water that is not contaminated with harmful chemicals, such as those found in reclaimed water. Since Northern Arizona University uses reclaimed water for irrigational purposes, our project outlines the need of NAU to provide the wildlife that resides on and around its campus with sources of potable water, such as bird baths. Through providing alternative sources of drinking water to wildlife, NAU will promote the reduction of the unnecessary harmful effects of reclaimed water and progress its commitment to sustainability.

Its estimated watershed area is roughly 650,000 km2 (250,965 mi2).Water from every river has unique properties, like temperature, specific conductance, pH, light transmittance, suspended sediments and organic matter content. This allows us to make a distinction between them. As smaller tributary rivers join the main stem of the Kolyma, we can see their influence in the change in water chemistry across the width of the river. Some of these tributary channels include the Malinky and Bolshoi Annui Rivers that join together just before they meet the Kolyma, and the Stadukhino River that meets the Kolyma further downstream. We do not yet understand why there is minimal mixing between Kolyma waters and some of its tributaries. At one of our measuring sites we identified three separate water masses across the Kolyma just downstream of where it meets with the Stadukhino River. Our data suggest these waters originated from the Annui Rivers along the right bank of the Kolyma, the Stadukhino River along the left bank, and Kolyma waters in the center of the channel. Upstream of the Stadukhino confluence, we identified only two distinct water masses including those from Annui waters on the right bank, and Kolyma waters along the rest of the channel. These differences could be explained by the shape of the river bottom and flow patterns at the time the measurements were taken. This research shows that we can further understand the transport of carbon and other materials across arctic rivers as they move downstream.

We are designing a device capable of changing the strength of a magnetic field with an adjustable current source. This change in magnetic field strength will change the viscosity of the MR fluid to compensate for certain ground conditions. The current produced by our circuit will adjust to changes in terrain, which will be translated from data gathered from accelerometers attached to the damper itself. This results in a responsive bike damper system, allowing for a smooth and comfortable ride for the rider. In conclusion this damper will not only effectively eliminate bumps on the road, but will give bike riders a damper capable of traversing multiple terrains seamlessly and efficiently.

Batteries lack power, the ability to rapidly charge and discharge, and have adverse environmental consequences. Traditional capacitors remedy this issue; however, they have a limited ability to store an electrical charge known as capacitance. Our group has been optimizing the electrical formulation of a structural supercapacitor characterized by high energy density. A structural supercapacitor (SSC) developed by our group is an electrical double layer capacitor utilizing a solid polymer electrolyte (SPE) and a high tensile strength composite material. This allows for the SSC to have structural integrity within an infrastructure. SSC may take over applications currently dominated by batteries because the SPE offers an extended shelf life and prevents hazardous chemicals from permeating into the environment. In addition, our capacitors will be an effective option for storing and accessing solar and wind energy due to the combination of high power and high capacitance. Prototype SSCs were fabricated in varying manufacturing conditions and formulation; the curing temperature and pressure, as well as the amount of lithium salt in the SPE. Capacitance and leakage resistance were evaluated using cyclic voltammetry and Ohm’s law to determine conditions yielding capacitors with the optimum electrical properties. Drain, Matt Faculty mentor: Thomas Paradis, College of Social and Behavioral Sciences (SBS) Water Quality and Scarcity Issues in the Southwestern United States My project will discuss current issues in the Southwest United States regarding the quality and the scarcity of water. Some things that will be briefly discussed are global warming trends that affect the quality of water and how it is affecting the supply of underground water as well. Water use and how illicit drugs have been found in water supplies which affect our health. Growing populations and demands for different water uses will be discussed and the actions that are being taken regarding these issues.

To reduce these risks, it is necessary to coat the roadways with cinders or chemicals that lower melting temperatures and increase traction. Until recently, cinders were the primary option for de-icing roadways but due to their effect on vehicle aesthetics, communities have focused on using chemical salt solutions instead. Studies have shown negative impacts of salt chemicals for deicing purposes lead to plant damage, erosion, water contamination and animal poisoning. Because of environmental impacts from the chemicals used, a comparative analysis is needed to quantify the best choice for removing ice from roadways. Drummond, Olivia Faculty mentor: Russell Benford, College of Engineering, Forestry and Natural Sciences (CEFNS) Defining Personality Through the Observation of Phoenicopterus ruber ruber This research intended to identify if flamingos demonstrated individual personalities, and to demonstrate the need for more research on this topic. With two flocks, one raised by humans and the other void of human interaction, the two could be compared. I hypothesized that a personality would be present with similar trends within individuals and differences between individuals. Five birds from each flock were observed for five consecutive days outside of the aviaries. A list of behaviors were ranked for each individual and each of these behaviors related to a human based personality analysis, the Big Five, which was adapted to represent the behaviors of flamingos. Because significant behavioral differences were present between individuals in both flocks and the similarities between, the question if flamingos had personalities was supported. These findings support the need for a continuation of this pilot study on the presence of personality in non-human species Overall, research on flamingo personalities can help humans better understand the causes for personality traits and how the individual can vary due to the environment and lead to more research of both human and non-human species. Drumright, Beau Nathan Heckathorne, Grant Masters, Patrick Schimmelbauer, Emerson Jones Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Alternative Power Source to Draw Underground Water The team was enlisted by Babbitt Ranches to research and design a power generation system that pumps underground water utilizing alternative energy resources. The water must be pumped from depths of 400 feet at a flow rate of 18 gallons per minute. The team examined and analyzed a number of potential resources and found wind energy and solar energy to be the most reliable and abundant resources available. Initial design efforts proved that such a system would require a large capital investment. Because the implementation of such a large system requires a large capital outlay, the team was challenged with analyzing a system with real time data utilizing Simulink®. The output of the simulation will detail power generated from a wind turbine, a solar array, and a diesel generator. The system utilizes a control system that chooses the resource to As of 4-19-13 UG Symposium Presentation Abstracts meet the need of 32 kW in the preferred order: wind turbine, solar array, diesel generator. Inputs into the system simulation are: solar irradiance and wind velocity. Outputs from the system include: power generated by the wind turbine, power generated by the solar array, power generated by the diesel generator (if the needs are unmet by the previous two sources), and the total power sent to the pump as chosen by the controller system.

By accepting the Medicaid expansion, Arizona stands to expand healthcare coverage to at least 300,000 new enrollees, while also making healthcare more affordable to thousands more who are already enrolled. On the contrary, for the states that choose to decline the expansion of Medicaid, results may have negative effects for the individuals living in poverty. In the following research analysis we will refer to two contrasting news articles. The first, “Medicaid Expansion Math Makes Sense”, argues to support Medicaid expansion in Arizona while the second, “Medicaid Expansion is Wrong Choice for Arizona”, expresses the opposing argument. Delving into these two contrasting articles will allow us to analyze which communication tactics are used in order to persuade citizens to agree with a particular position on Medicaid expansion in Arizona.

Gage, College of Engineering, Forestry and Natural Sciences (CEFNS) Determining the Purification of Angiogenic Proteins (CD47, TSP-1, VEGFR2) Angiogenesis is a physiological process that occurs in wound healing and embryonic development. Many protein interactions are involved in regulating and maintaining this pathway to prevent cancer and cardiovascular diseases. The focus of this project is to understand the molecular interactions between three proteins involved in this pathway: Integrin Associated Protein (CD47), Thrombospondin-1 (TSP-1), and Vascular Endothelial Growth Factor Receptor2 (VEGFR2). Currently, the goal of my work is to design expression and purification conditions for the CD47 protein, while others in the lab work with VEGFR2 and TSP-1. We have determined that ideal expression occurs when transformed E. coli cells are induced at OD600 about 0.6, 25 degrees Celsius, and 90 rpm. The protein of interest is HIS- and GST-tagged and has been purified to about 80 percent purity using affinity Ni2+ chromatography. We are currently assessing using GST chromatography to further purify the protein. Once we have pure protein we can study the binding of this region to the other proteins it associates with and those studies could facilitate drug development in the future. Edenhofer, Nathan Faculty mentor: Lori Poloni-Staudinger, College of Social and Behavioral Sciences (SBS) Feminicide's Relationship to the Genocide in Guatemala Aims: This research seeks to understand the feminicide, the gender specific killing of women with state responsibility, that is occurring in Guatemala, and how it is related to the events that took place during the country’s 36 year civil war, the genocide, and the amnesty granted to those involved in the war. This seeks to understand why this feminicide is happening, and who the perpetrators are. Methods: This paper used a synthesis of scholarly work on the subjects of feminicide and the Guatemalan civil war and genocide, which were compared to show similarities in the violence against women during the war period and the present. Results: The tactics used by the military in the civil war were characterized by extreme brutality, especially against women. This learned brutality has continued into the present, as the impunity granted to the perpetrators has allowed the violence to continue. This is evident in the brutality that is especially present in female homicides. This feminicide is also fostered by misogynistic laws, and continues unchecked due to police and legal system failure. Gangs, perpetrators of domestic abuse, and the police, who are likely to be more responsible than is reported, are committing the feminicide. Conclusion: The feminicide in Guatemala is happening because of gender related aspects of the civil war and genocide that, because of impunity, continue to influence Guatemalan society until the present. To combat this, possible action can include police reform, education over the war and genocide, and trying war criminals. Eide, Stefania Cary Grossart, Ryan Reardon, Madison Whybark-Marshall Faculty mentor: Calvin Brant Short, College of Social and Behavioral Sciences (SBS) As of 4-19-13 UG Symposium Presentation Abstracts Crisis Communication and the Federal Emergency Management Agency When disasters occur across the United States, there are various resources that survivors can utilize in order to get back on their feet. However, these programs and services do not necessarily grant enough time, money, and attention to the survivors that is needed for their recovery. Organizations such as FEMA, or the Federal Emergency Management Agency, have developed programs to aid with these disasters, but many are still remaining homeless and helpless after their needs haven’t been met by agencies such as FEMA. The various ways in which FEMA communicates with the public in regards to these disasters is a major influence on whether or not these people being affected are able to get back on their feet. Communication's Structuration Theory can be utilized in specifying these publics as being unique from other groups of homeless individuals; therefore, requiring personalized attention from FEMA. This theory can also be used to understand the state of those impoverished by disasters. These people become a structure in themselves who are different from those who are homeless and in poverty due to other circumstances. Due to the immediate effect on those dealing with a disaster, and therefore, living in poverty, they become a separate structure. This category of impoverished peoples needs to be more specifically focused on in order to bring them back to their feet. By evaluation of FEMA's current communication process when dealing with those put into poverty due to natural disasters, the case can be made towards how to get them back to good economic standing. Eliason, Jessica Faculty mentor: Cat Sullivan, College of Engineering, Forestry and Natural Sciences (CEFNS) Farm to Fork on Northern Arizona University Campus The accessibility of local foods appears to be a challenge due to two specific factors: cost and seasonal growing. This internship allowed cooperative teamwork with Catherine Sullivan who is the Sustainability Specialist on Northern Arizona University’s dining staff to challenge these two specific factors. The main goal of this internship was to deliver a Farm to Fork meal to Northern Arizona University’s campus, while also learning how to illustrate the benefits of local consumption, organize a non-profit event, and grow produce seasonally. During this internship, there were tasks of writing letters, communicating with Arizona Farms (i.e Duncan Family Farms), attending meetings, researching seasonal produce charts, and organizing the Farm to Fork event. As a result, this internship displayed how priceless local foods are. This internship delivered knowledge on when to grow certain produce for the best yields. The Farm to Fork meal was hosted on January 29, 2013 at one of Northern Arizona University’s main dining halls. Elliott, Cassidy Faculty mentor: Deborah Craig, College of Health and Human Services (CHHS) Extracorporeal Shock Wave Therapy: An Alternative to Surgery in Musculoskeletal Conditions Context: Extracorporeal shock wave therapy (ESWT) is becoming a more popular alternative to surgical treatments of musculoskeletal conditions. The more common conditions are plantar As of 4-19-13 UG Symposium Presentation Abstracts fasciitis, Achilles tendinopathies, lateral epicondylitis, and tendinitis of the rotator cuff. Researchers are still unsure of how this therapy works, but many studies show positive results. Purpose: This literature review is to look at how extracorporeal shock wave therapy works and to determine if it is an effective alternative treatment to surgery for soft-tissue conditions. Methods: The following databases were used to for research EBSCOhost, CINAHL Plus, Cochrane Library and Medline (PubMed). Keywords used were, but not limited to: extracorporeal shock wave therapy, shock wave therapy extracorporeal shockwave therapy, shock waves, plantar fasciitis, and Achilles tendon. Results: Patients who were treated with ESWT for Achilles tendinitis, patellar tendinopathy, and plantar fasciitis had positive mainly positive outcomes for pain and activity levels. The studies showed a lower time average in return to activity. Several studies with the outcome on the side of surgery still discussed the benefits of ESWT, and how the treatment is still an option worth noting. Conclusion: Although very little is understood on how ESWT works, studies are showing positive results. This could be a beneficial alternative to surgery, after the failure of conservative treatment, for athletes with chronic musculoskeletal conditions such as plantar fasciitis or Achilles tendinopathies. Ellsworth, Joshua Faculty mentor: Cindy C. Browder, College of Engineering, Forestry and Natural Sciences (CEFNS) Design of Inhibitors of Methionine Biosynthesis The rise in prevalence of antibiotic resistant strains of bacteria looms as one of the great threats to public health in the coming decades. Methicillin and Vancomycin resistant strains of staphylococcus have been found in hospitals throughout the United States, and reports of drug resistant strains of tuberculosis are on the rise across the developing world. The goal of this research is to generate a new class of antibiotic compounds by focusing on the disruption of methionine biosynthesis in bacteria. While methionine is one of the nine essential amino acids that humans must obtain from their diet, plants and bacteria are capable of methionine biosynthesis. The process relies on the cystathionine γ-synthase enzyme (CGS), which converts O-succinyl homoserine (OSHS) into cystathionine. The CGS enzyme is dependent on pyridoxal5’-phosphate (PLP), and previous work in our group has determined that both OSHS and PLP are involved in bonding to the active site on the enzyme. The focus of this research has been to create a library of compounds that are structural analogs to the OSHS-PLP complex, similar enough to bond to the active site of the enzyme but possessing substituents that inhibit further activity. Inhibition of CGS would kill bacteria but have no effect on humans as they lack the enzyme. These compounds have been synthesized by converting aryl amines into the corresponding aryl azides, then reacting them with terminal alkynes to form triazoles. The triazoles that demonstrate CGS inhibition will serve as templates for the next generation of compounds.

School of Music., College of Arts and Letters (CAL), Honors Program Neocasticismo Y Algo Mas: Rodrigo's "Concierto de Aranjuez" In response to late romantic musical ideals, the 20th century experienced blooms of new musical trends. Some composers used Neoclassicism to return to the past and other composers embraced the new harmonic techniques. Joaquin Rodrigo (1901-1999) embraced them both. His blending of 20th century harmony and the aesthetics of traditional music is a staple of Rodrigo’s compositional technique; however, there are also elements of Spanish folk music in his compositions. This folk aspect of composition is something that set Spain apart from the mainstream neoclassical trend. In my research, I analyzed the first movement of the Concierto de Aranjuez Para Guitarra Y Orchestra and examined how this piece exemplifies Rodrigo’s fusion of these compositional techniques, which has been dubbed as Neocasticismo. With the lens of Neocasticismo, we are able to fully understand the compositions of Joaquin Rodrigo and the compositions of his contemporaries in Spain. To be able to comprehend the concerto, I took an ethnomusicologist approach and studied the folk music of Spanish guitar, particularly Flamenco. I also did an in depth analysis of the Concerto itself. Finally, I studied the life of Rodrigo, including the events that led to the composition of the Concerto. Through the eyes of Neocasticismo, we can see that this concerto is a prime example of the unique trend in composition that happened in Spain. As a beautiful personification of Spain itself, the Concerto has come to inspire a new generation of composers and guitarists to carry on the ideals of Neocasticismo.

After gathering research, we can find possible solutions on the way that society communicates about this new class of people. As of 4-19-13 UG Symposium Presentation Abstracts Fader, Zach M T. Isbell, C M. Pace, K C. Nishikawa Faculty mentor: Kiisa Nishikawa, College of Engineering, Forestry and Natural Sciences (CEFNS) Joint angles and jump variation between wildtype and mutant mouse mdm genotypes. Jumping is a locomotor behavior used by many organisms, including mice, that can help us elucidate how muscles work. Animals performing vertical jumps are thought to utilize elastic components to store energy and increase jump height. The protein titin is known to contribute to the elastic properties of muscle. MDM mice have a deletion in the N2A region of their titin protein and exhibit different active and passive in vitro muscle properties compared to wildtype mice. MDM mice have also been shown to have lower jumping performance than wild type mice, but the limb kinematics of jumping are unknown. It is also unknown how jump kinematics change with increased jump performance Therefore, the goal of this project is to determine whether MDM genotypes differ in their joint angles from wild type mice over a range of jump heights. Homozygous mutant and wild type mice were filmed performing voluntary jumps using a high-speed digital imaging system. Locations of the mouse hind-limb were digitized and metatarsal, ankle, and knee joint angles were calculated. For both genotypes the ankle had the largest excursion. For wild types the metatarsal joint usually had a larger excursion than the knee; whereas, the mutant showed the opposite pattern. Additionally, wild type mice exhibited a greater range of movement in both the metatarsal and knee joints. By combining different kinds of whole animal locomotion studies, such as jumping, with our muscle lever studies, we will broaden our understanding on how titin contributes to muscle function and movement. Farley, Sam Faculty mentor: Stephen Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) Mean Crowding of the leech, Helobdella stagnalis in a Laboratory Setting Helobdella stagnalis is a benthic predacious leech that exhibits postzygotic parental care. From 2007 to 2010, we demonstrated in the field at Montezuma Well that a sister species, Helobdella blinnii has demonstrated a tendency to crowd into groups at all the life history stages, especially during the brooding season, but this crowding behavior has yet to be replicated in a laboratory environment. We created a microcosm experiment to investigate whether H. stagnalis also exhibits this crowding behavior. We set up four tanks with leeches from the White Horse Lake population, half containing unrelated leeches and half containing related leeches. The “unrelated” tanks meant that no two leeches shared the same parent, while the “related” tanks contained leeches such that every leech shared a parent with at least one other leech. Five other tanks were set up the same way, three “unrelated” and two “related” tanks with leeches from the Rio de Flag population. Each tank was separated into quadrants with two rock choices to determine the degree of patchiness with respect to populations and life history characteristics. Lloyd’s (1967) index of patchiness is the ratio of mean crowding of a population to its mean density, defining mean crowding as the mean number of neighbors per individual per unit area. We found that these leeches do exhibit mean crowding, especially during the time of brooding.

Since invasive species exhibit different pytomorphology than native plants (especially in root structure), it was predicted native plants have greater proportions of belowground carbon biomass than non-native plants. This could cause an increase in carbon movement from a carbon sink (growing plants) to a carbon sources (decomposing or volatized plant matter). Five selected sites near Kane Ranch in northern Arizona are currently experiencing a non-native plant species invasion. By sampling and analyzing percent carbon for invasive non-native plants (Cheatgrass, Russian Thistle, and Crested Wheatgrass) and their respective native pairings (Six Weeks Fescue, Wedgeleaf Draba, Fendler Three-Awn, Mutton Grass, Rabbit brush, and Squirreltail grass), proportions will be determined proportions of above and belowground carbon biomass storage that will describe carbon sequestration and determine the consequences of changes in ecosystem composition. From the results, a GIS kernel density map illustrating areas with potentially large carbon outputs due to exotic species invasion will be generated. Farrell, Kevin Faculty mentor: George Gumerman, Honors Program The Effects of Worshiping a Cow This research paper will look at the Hindu religion and the animal which they see as sacred, the cow, in order to identify the effects that worshiping cows has on their economy. In the Hindu society it is forbidden to kill cows; however this has not always been the case. In the early Vedic days having cow meats was a sign of wealth. Gradually, due to the influence of Buddhism, many middle and low caste citizens began to dislike the killing of cows, eventually leading to the total ban on killing cows. In modern times Hindus do not kill cows and use them solely for milk and farming and move them to animal shelters when they grow old.

An important requirement for this space was to hold both a mobile ping-pong table and a small sized pool table, which is difficult to achieve considering the amount of open space needed to surround the tables. We were able to overcome this challenge by placing the heavy pool table so As of 4-19-13 UG Symposium Presentation Abstracts it wasn’t an obstruction to the space and placed the ping pong table where it could easily be moved out of the way for large gatherings. Another challenge we faced was the client’s budget for the space. The client wanted some new elements added such as paint, furniture and new cabinetry. However, the budget was very limited. We found cheaper alternatives for seating and accessories for the space, saving most of the budget for the more expensive items, like cabinetry. This allowed us to stay within the client’s budget. Although the amount of space and money available posed a challenge, we were able to design a flexible floor plan that worked great for the space and the client.

CO2 is relatively harmless, though in massive quantities, it is believed to be one of the leading causes of global warming. While greener technologies are being developed to reduce emissions, the number of automobiles worldwide continues to grow, increasing greenhouse gases. Our goal was to develop a device that would break down CO2 emissions from a car into Carbon and Oxygen. A Van De Graaff generator was to be used to prove the concept. A carbon dioxide monitor was obtained to detect decreasing CO2 concentrations in parts per million over ten minute intervals. Once proven, the data would be used to develop an efficient CO2 breakdown device. Our research determined that too many environmental and health concerns exist to proceed within cost constraints.

While the first requirement for any implantable biomaterial is that it be biocompatible, in reality most biomaterials are only minimally biocompatible, invoking immune responses by the body. This has led to a trend towards natural protein-based biomaterials. This poster reports on mechanical characterization of electrospun tissue scaffolds formed from blends of collagen and human tropoelastin, an elastic structural protein found in skin, vasculature, and other tissues. The electrospun tropoelastinbased scaffolds have an open, porous structure conducive to cell attachment. Mechanical properties were tested for scaffolds consisting of 100% tropoelastin, 100% collagen, and 1:1 tropoelastin/collagen blends. The mechanical testing results showed that the materials exhibited vastly different mechanical properties when tested dry vs. hydrated, exhibiting a three order of magnitude change in elastic modulus for tropoelastin. Crosslinking similarly changed the mechanics by increasing the stiffness. The elastic modulus of a pure collagen scaffold was higher than the pure tropoelastin scaffold and the modulus of a 1:1 blend fell between the two. Finally, the scaffolds demonstrated a viscoelastic character when tested at variable strain rates, with the materials becoming stiffer at the higher strain rates. By systematically varying strain rate, protein composition, and crosslinking, these results demonstrate how protein scaffolds might be manipulated as customized biomaterials, potentially improving biocompatibility through minimization of compliance mismatch between the scaffold and the tissue environment. Future investigation will continue to characterize the mechanical behavior of tropoelastin tissue scaffolds in effort to tune them to specific mechanical characteristics.

El Centro de Miembros Artificiales is a non-profit prosthetics clinic in La Paz, Bolivia. They provide low or no cost lower limb prosthetics to low-income Bolivian amputees. The clinic faces challenges with premature deformation and failure of their current foot and ankle prosthetic designs. This project aims to design an improved foot and ankle prosthetic for use in the clinic. The foot must be low cost, easily manufactured using the limited equipment in the clinic, be compatible with their current knee and leg design, and be durable enough to perform in the mountainous terrain at the As of 4-19-13 UG Symposium Presentation Abstracts satisfaction of its user. The new design retains the forefoot design that is currently in use with the addition of a ‘C’ ankle. The ‘C’ ankle design is widely used in passive prosthetics to improve the energy storage of the ankle. It will absorb some of the impact of heel strike and relieve some of the stress from deflection seen in the rest of the foot to improve the overall fatigue life of the design. The manufacturing process uses a concrete mold held in a wooden press to form stacked sheets of heated polypropylene copolymer into the designated foot shape. Post-process cuts are then required to complete the foot. The resulting prototypes were tested both statically and cyclically at the toe and the heel by modifying the press to administer a controlled load.

Fotino, Giovanna Faculty mentor: Jennifer Musial, College of Social and Behavioral Sciences (SBS) Escaping the Ivory Tower: Parenthood within Academia In this essay, after exploring personal accounts of student who are parents and faculty who are parents, I examine how the social constructs of parenthood are constructed in the through the socio-cultural contexts in which specific behaviors take place. I argue that these behaviors and contexts create a binary in which certain traits are deemed as being “good” and socially acceptable for motherhood and fatherhood compared to other traits labeled as “bad” and unacceptable for motherhood and fatherhood. These binaries and the public policy that surrounds them uphold and perpetuate a distinct hierarchy— a patriarchal hierarchy with a core of heteronormativity. By discussing how race, class, age, gender, and sexuality intersect have been historically and are currently utilized to construct the concept of parenthood. I assert that college students and faculty who identify as parents face specific barriers and challenges within academia. In the conclusion of this essay, I examine the ways in which the “ivory tower” can eliminate these barriers and create a bridge between the current academy-community gap that currently exists.

The use of prophylactic antibiotics was believed to prevent the development of endocarditis secondary to bacteria entering the blood stream during dental work. This is a literature review of the evidence warranting a change in previous recommendations. Reviewed resources indicate that there is not a need for prophylactic antibiotic use in patients with mitral valve prolapse, rheumatic heart disease, etc.; however, the continued use of prophylactic antibiotics in patients with mitral valve replacements when having invasive dental work is still recommended to prevent endocarditis and other complications. Frank, Smith Faculty mentor: Thomas Paradis, College of Social and Behavioral Sciences (SBS) Applications of Forest Thinning beyond the Wildland Urban Interface The project will look into the application of forest thinning beyond the wild land urban interface. Much work has been done regarding thinning and healthy forest projects close to towns and cities but large scale, cost effective projects concerning thinning in the forest at large are limited. This project will look into other examples of forest health projects and draw on past research to formulate a plan for the forest surrounding Flagstaff. Fredrickson, Marcus Faculty mentor: Tom Paradis, College of Social and Behavioral Sciences (SBS) Blending Theory and Interactive Learning: The San Francisco Volcanic Field It is important to understand the how geologic processes and also to have an understanding of physical landforms in a region. Technology has greatly changed the way that we approach teaching and learning. It is now possible to learn in a more hands-on way that can help to make As of 4-19-13 UG Symposium Presentation Abstracts learning more fun and also easier to understand the subject. This type of learning will be accomplished by creating a map that plots volcanic features as points. When these points are clicked on a picture of the feature will appear along with a brief description of this landform. This will supplement more conventional learning in a new and hands-on way. The purpose of this research is twofold. First, this paper provides a geographical description and various theoretical explanations for a defined physical region. This material will provide the background understanding for various educational approaches to understand the region. Second, the research here identifies and applies one interactive platform that will help to promote education and hands-on learning. This research therefore attempts to integrate theoretical knowledge of physical geography into an interactive learning program. Frey, Emmaline Faculty mentor: George Gumerman, Honors Program In a Pickle: Food Waste in America and Potential Solutions Food waste in America today is large and important issue and one that continues to grow. While this is a discouraging topic, there are a variety of interesting and effective actions being taken at a grassroots level to begin to combat the problem. Individuals have taken matters into their own hands and have adopted methods such as composting, buying local, and even “freeganism” to lessen their impact on the earth when it comes to food waste. While there is still a long way to go to resolve this complicated issue, these small steps will lead the country in the right direction. Friend, Madeline Faculty mentor: Angie Moline, College of Engineering, Forestry and Natural Sciences (CEFNS), Honors Program Experiential Education: The Difference Between Learning and Truly Understanding Education reform within the United States is floundering under competing political agendas, standardized teaching mandates, nationwide fear of losing proficiency in science, technology, engineering, and mathematics (STEM) disciplines, and a de-emphasis on liberal studies education. However, experiential and field-based education programs within the private sector are increasing in prominence. Despite the growing popularity of field programs such as the National Outdoor Leadership School (NOLS) and Outward Bound, experiential education is uncommon in most American K-12 schools and universities. The lack of interdisciplinary field-based courses in the education system neglects the vibrant necessity of humans to engage in creative responses to problems and ignores the methods through which most people retain information. Experiential programs, such as field-based and service-learning experiences, enable participants to learn multidisciplinary leadership skills and enjoy education through holistic opportunities for learning. Experiential education should be implemented in school curriculums because real-world application leads to greater knowledge retention. Through this paper, literature pertaining to experiential education was analyzed and used to create and implement an experiential education curriculum in a local Flagstaff middle school. By using these approaches to learning, students are able to transition from rote memorization and As of 4-19-13 UG Symposium Presentation Abstracts regurgitation of facts to applicable understanding. In my highly interactive presentation, I highlight current education concerns and address the value of experiential education, using my research as a case study.

Fry, Elisabeth Faculty mentor: Zsuzsanna Gulacsi, College of Arts and Letters (CAL) Ritual and Religion in Holocaust Photography: Lodz Ghetto 1939-1945 Based on the study of photographs taken by Mendel Grossman and Henryk Ross in the Lodz Ghetto during the German occupation of Poland in WWII, this presentation explores ways in which these photographs document an important aspect of Jewish identity and reflect changes due to the extreme environment. Fuentes, Elisa Elisa Fuentes, James Moench, Eric Sotelo, Andrea Hieser, and Teri Croy Faculty mentor: Constance Brown, College of Engineering, Forestry and Natural Sciences (CEFNS) Dance Program for Special Needs Individuals This customized dance program was developed using the effective-based program design to address the combined physical, social, mental and cultural needs of individuals with physical disabilities within the Prescott and Prescott Valley and quad-city region. This experience is aimed to promote kinesthetic development as well as foster community cohesion amongst this population. At the Dance Studio we provide all the necessary resources for dance instruction, choreography and kinesthetic development. The components of the activity-based program enable special needs persons to experience a fun and motivating community that promulgates trust, commitment, and personal accountability. In addition, this program provides a framework and network for other special needs activity-based programs in the quad-cities. A complete session of this program is designed to run every two weeks for one year with eight classes per session. Over the period of the session, participants will be measured for flexibility, weight loss, music awareness, self-esteem, and mobility. Both formative and summative evaluations will be done over the duration of a session. At the end of each session, participants will be evaluated to As of 4-19-13 UG Symposium Presentation Abstracts determine the degree to which dance and music contributes to the improvement of the participants overall well being in terms of social, mental and emotional health. Fulton, Brooke Faculty mentor: Jennifer Musial, College of Social and Behavioral Sciences (SBS) Body Image In America My presentation will focus on the history of body image in the United States, including how average girls and women perceive themselves today. It will include things like statistics involving plastic surgery, models in today's society, depression rates, and how fashion and beauty affect American life. Gaddo, Emily Faculty mentor: Paul Gazda, College of Engineering, Forestry and Natural Sciences (CEFNS) Sustainable Landscape Maintenance Internship This study’s objective was to find a sustainable alternative to using herbicide and pesticide applications to the Northern Arizona Universities landscape. The research conducted was then published to educate the community about the findings. Students on five test and five control plots around campus completed fieldwork. The transect method was used to count the number and types of weeds found on both test and control plots. On the test plots, weeds were extracted using weed eaters and hand tools. On the control plots, the weeds were untouched and continually sprayed by the grounds department as normal. An overall appearance test was conducted weekly on both test and control sites. The collected data was input into excel spreadsheets and analyses were conducted. It was found that the aesthetic appeal of the grass was found to be higher of the test plots. This is a continuing study, and more research is being conducted to target the specific weed types, as they have been identified in the data. Currently the use of an organic corn meal has been found to create a healthy grass color and appearance on the test plots. Soil pH levels are also being tested and it has been recommended to the grounds department that the mower height should be altered. Gamez Molina, Vivianna Faculty mentor: Terry Baxter, College of Engineering, Forestry and Natural Sciences (CEFNS) Exchanging Gases Between Algae and Biogas in a Life-Support System Earth is a natural life support system providing oxygen, food, shelter, and water for our survival. NASA has interest in life support systems that would enable humans to survive space exploration. This project considers one aspect of a life support system; the integration of anaerobic digestion and algae biomass production. Anaerobic digestion decomposes organic wastes, producing methane and carbon dioxide in biogas without consuming oxygen. Algae biomass production uses carbon dioxide in photosynthesis and produces oxygen, which can be used to breathe or to combust methane gas. Laboratory tests were conducted to demonstrate how As of 4-19-13 UG Symposium Presentation Abstracts biogas can be bubbled through liquid from an algae growth process to exchange biogas carbon dioxide needed by the algae for oxygen needed to combust methane. Both of these processes can benefit one another. Garcia, Ashley Kaitlin Booth and Caitlyn Rogers Faculty mentor: Brant Short, College of Social and Behavioral Sciences (SBS) A Theoretical Approach to Understanding the Culture of Poverty: A Call for More Positivity Poverty can be considered as a non-dominant culture in the United States. Stereotypes and the dominant views of the poor have led to a negative perception of people living near or below the poverty line. More positivity is needed regarding the portrayal of the poor and in remedying the problem. One such area where more positivity is needed is in the media and its portrayals of the poor. First, communication theories are used to demonstrate how poverty can be considered as a socially constructed culture, which is often portrayed negatively or overlooked entirely by society. Next, the philosophies of philanthropists that positively impact the culture of the poor are explored. Lastly, nations that have a more positive outlook about remedying poverty are discussed. The issue of poverty is not just about money; it is about stereotypes, portrayals, and perceptions. America needs to have a more optimistic view that does not consider people living at or below the poverty line as “the other” by following the examples of philanthropists and other nations that are more optimistic. This would serve as the first step in addressing the ever-looming problem of poverty. Garcia, Lorissa Faculty mentor: Michael Lerma, College of Social and Behavioral Sciences (SBS) Acoma Pueblo Womens Leadership Roles Garcia, Ralph Sarah Thomas, Jacob Barrow, Matthew Valente Faculty mentor: Matthew Anderson, College of Social and Behavioral Sciences (SBS) Espresso Yourself The main purpose for the study was to establish a relationship that caffeine has between a person’s habitual sleep schedule and stress level. College students of both men and women (N≈100) participated in our study. Participants were selected using convenience sampling based on those enrolled in a Psychology 302W class. Besides being asked to take part in our Sleep and Stress survey, there were no treatment conditions present in our study. The Sleep and Stress survey included questions such as, “I have difficulty falling asleep,” and “In general, I remain confident when I make a mistake.” Results for these questions were assessed using a Likert rating scale. We utilized a Pearson’s r correlation to establish a relationship where caffeine will decrease sleep and increase stress. With these conclusions we hope to promote awareness As of 4-19-13 UG Symposium Presentation Abstracts regarding caffeine consumption producing a negative impact upon students’ college experience if not moderated appropriately. From these findings, we hope to have a better understanding upon whether caffeine has a substantial influence on sleep and stress compared to other student activities in college. Future research is still essential for caffeine’s effect on the human’s biological system and coping mechanisms that can help establish homeostasis.

Her prize was joint with that of Carl Ferdinand Cori "for their discovery of the course of the catalytic conversion of glycogen." They also shared the other half of this Nobel Prize with Bernardo Alberto Houssay "for his discovery of the part played by the hormone of the anterior pituitary lobe in the metabolism of sugar". Gerty Cori was the first of only a handful of women to be awarded the Nobel Prize in this category, even today. Gelety, Christopher Faculty mentor: Melissa Birkett, College of Social and Behavioral Sciences (SBS) Comparison of the Effects of Conscientiousness on Iowa Gambling Task Performance As of 4-19-13 UG Symposium Presentation Abstracts This presentation will discuss the interaction between self reported conscientiousness and physiological measures, skin conductance and heart rate, on performance with the Iowa Gambling Task (IGT) in Undergraduate Psychology students at Northern Arizona University. This study also examined any differences between two unique administrations of the IGT in this population: the officially licensed Bachura administration and that of the freely available and open source PEBL psychological battery version. The IGT is a evaluation of cognitive decision making where participants are tasked with picking a card from 4 unique decks where each card will either give a reward or penalty in the form of cash payout or deduction. The participants are instructed to maximize the amount of cash earned from a starting 2000 dollars in the 100 card choices they are permitted. Of these decks, two are rigged to be disadvantageous and two decks are set to be advantageous. The decision making prowess of participants is evaluated in their ability to reliably and quickly distinguish between these decks by consecutively choosing cards from the two advantageous decks. It is expected that there will be no difference in recorded heart rate and skin conductance measures between the groups of different administrations. It is also expected that with an increase in conscientiousness there will be an increase in time spent between each card choice and an increased frequency of advantageous deck choices. Gene, Erelda Miranda Yellowhorse Faculty mentor: Roger Bounds, Hendrik De Heer, Scot Raab, College of Health and Human Services (CHHS) The pathway of academic success programs for AI/AN students, how is it used and where does it lead? Arizona and tribal institutions of higher education offer many academic success programs that support Native American & Alaskan Native students. Such programs are typically created to meet specific funding requirements and are created in isolation from each other. Student participants, however, often participate in many of these programs throughout their time in the higher education system. Based on the evaluation data from The Partnership of Native American Cancer Prevention (NACP), the separate programs are presented here such that inferences can be made regarding how these separate programs have been used by AI/AN students and preliminary observations are presented about the impact these programs have on AI/AN student trajectory. Although direct relationships are difficult to articulate, this project attempts identify and clarify how these various programs have been used as a pathway to success by the AI/AN students. Gennarelli, Joseph Josh Stone, Chris Allender, Dr. Apichai Tuanyok Faculty mentor: Apichai Tuanyok, College of Engineering, Forestry and Natural Sciences (CEFNS) Genomic Islands in Burkholderia pseudomallei The Burkholderia genus is composed of Gram-negative, rod-shaped, bacteria with members that can cause disease in human, animal, and plant hosts. Our work centered around B. pseudomallei, which causes the life-threatening disease Meliodosis in humans, and seven species of close As of 4-19-13 UG Symposium Presentation Abstracts genetic relatives, some of which do not cause disease. We aimed to discover if any mobile genetic elements called genomic islands (GIs) were shared between these pathogenic and nonpathogenic species, and if any GIs may confer fitness advantages to B. pseudomallei for overcoming host defenses and causing disease. We used in silico methods to search for tRNA coding genes in the DNA sequence to locate GIs because they are frequently inserted next to tRNA genes. There GIs were then characterized according to their predicted function based on their genomic content. The GIs contained multiple genes that may affect overall fitness and virulence in each strain. Also, some elements were shared among these Burkholderia spp. Therefore, we have further evidence that GIs may indeed help certain isolates cause disease while others do not. Geraldo, Michael Faculty mentor: George Gumerman, Honors Program Essential Fast Food After reading Fast Food Nation by Eric Schlosser, I have concluded that the fast food industry needs some justification and deserves a better rap. With numerous published articles and books about the negativities surrounding the fast food industry, it is no wonder why it is thought of as a detriment to the American and our diet. We are merely blinded by ideas spilling from books like Fast Food Nation; ideas as bountiful as the stars. And that being said, I wish to open up the eyes to the blinded and show them the many benefits of fast food. Fast food, as an entity of the most encompassing culture in the world, brings many a joy and simplicity in a happy humble way through cost, taste, and convenience. Through some diligent and thorough research, I hope to uncover the lighter side to fast food. With fast food having a reputation of a detriment to everyone and everything, there has to be some silver lining to the “dark cloud” of fast food. I can think on my own, some ideas that are a benefit of fast food. Cost, taste, and convenience of fast food open up topics in fast food that enlighten to the bright side of the industry. And with these topics, stem subtopics. Some subtopics are alternatives to fast food, the cost of the alternatives, relative taste of the alternatives, convenience of the alternatives, and preferences of the American. And with these all encompassing topics and subtopics, I can gather a broader understanding of what fast food has to offer. Gerardo, Gina Faculty mentor: Cindy Browder, College of Engineering, Forestry and Natural Sciences (CEFNS) Development of Novel Antibacterial Drugs Tryptophan is an essential amino acid in humans and plants, meaning it cannot be produced in one’s body and must therefore be acquired from a food source. Bacteria are unique in that, unlike humans, they can produce their own tryptophan. Tryptophan biosynthesis requires several enzymes that, when inhibited, could disrupt the production of that essential amino acid. Many of these given enzymes in the tryptophan pathway have been shown to have no human homologues. This is important because a drug with no human homologues will not interrupt the human As of 4-19-13 UG Symposium Presentation Abstracts biosynthetic pathways when introduced into the system. This is because it is not a molecule that is active in the body’s necessary processes. Due to these findings, inhibitors of these enzymes have been investigated for the development of antibacterial drugs. Our research focuses on producing inhibitors that target the forth step of the tryptophan biosynthesis pathway, where 1(o-carboxyphenylamino)-1-deoxyribulose 5-phosphate (CdRP) is converted to indole-3-glycerol phosphate (IGP) via indole-3-glycerol phosphate synthase (IGPs). The compounds that are being produced will mimic CdRP, which we intend to use to prevent the pathway from producing IGP. Using promising results from a first generation library of compounds, our research focuses on emphasizing the design and production of a second-generation library of potential inhibitors. These compounds are synthesized through a nitrile oxide cycloaddition. Our experimental design rationale, methodology, and preliminary results from in vitro screening studies will be presented. German, Sabrina Owen P. Leiser, Jeff T. Foster, Paul S. Keim Faculty mentor: Jeffrey Foster, College of Engineering, Forestry and Natural Sciences (CEFNS) Isolation and Characterization of Clostridium botulinum from Commercial Honey Clostridium botulinum is a gram-positive, anaerobic, endospore producing bacterium that produces the botulinum neurotoxin (BoNT), which is one of the most toxic bacterial neurotoxin to humans. BoNT is known to cause botulism in infants and adults who ingest the bacterium, yet is also widely used in medical and cosmetic procedures. C. botulinum is found in a number of environments, including commercially produced honey. In this pilot study, we surveyed 32 commercial honey samples for the presence of C. botulinum spores. Honey samples were obtained from a diverse geographical range, and were of a variety of types (e.g. raw, processed, etc). Two confirmed C. botulinum isolates were obtained from a single sample of honey and were further characterized by their BoNT gene sequences, and placed into our current phylogenetic understanding of this organism. Although the number of isolates we obtained in this proof-of-concept study is limited, we have validated our isolation and characterization techniques. Our aim is to broaden the understanding of true global diversity of C. botulinum by obtaining novel toxin-producing isolates from around the world. Gilbertson, Selina Faculty mentor: Dana Ernst, College of Engineering, Forestry and Natural Sciences (CEFNS) Investigations of T-avoding elements of Coxeter groups Coxeter groups can be thought of as generalized reflections groups. In particular, a Coxeter group is generated by a set of elements of order two. Every element of a Coxeter group can be written as an expression in the generators, and if the number of generators in an expression is minimal, we say that the expression is reduced. We say that an element w of a Coxeter group is T-avoiding if w does not have a reduced expression beginning or ending with a pair of noncommuting generators. In this talk, we will state the known results concerning T-avoiding elements and discuss our current work in classifying the T-avoiding elements in Coxeter groups of type F.

The challenge wall will serve as a team-building exercise. Groups of people will use the wall with the goal of getting every person over the wall. The wall is 12 feet high with a platform that is 9 feet from the ground. The project consists of designing two support poles for the wall, two support poles for the platform, and the deck-to-wall and wall-to-pole connections. Geotechnical analysis is used to determine the length of the pile and the foundation design. Structural analysis is used for the rest of the design with a focus on the construction of the platform. Gillman, Kelli Nick Rutherford, Wieland Mego Faculty mentor: Mathew Anderson, College of Social and Behavioral Sciences (SBS) Thumbs Up! In Flagstaff, hitchhiking is a topic that is not widely discussed, but highly utilized. We, as a group, found a common interest to find what makes individuals choose to pick up hitchhikers in our city. Our hypothesis that was tested is that college students at Northern Arizona University are more likely to pick up a hitchhiker that is a Caucasian female with blonde hair and a mesomorph body type. The variables that were tested are gender, ethnicity, hair color, and body type. Participants filled out surveys for both male and female potential hitchhikers, and were able to choose from options such as ethnicity, hair color, and body type. We also asked the participants if their choices were based on attraction, in order to eliminate or confirm that there is an outside variable contributing to and possibly skewing our data. We hypothesize that both male and female participants will not vary by gender in their selection of the previously defined “perfect hitchhiker.” Gobster, Chelsea Cierra Winters, Amanda Anderson Faculty mentor: Dierdra Bycura, Hendrik deHeer, College of Health and Human Services (CHHS) Biomechanical Analysis of Running on an Anti-Gravity Treadmill from a Rear View The Alter-G anti-gravity treadmill is a relatively new piece of equipment designed to support the user’s body weight during running and walking activities. The Alter-G has a lower body positive pressure chamber that has the ability to de-weight an individual in an effort to decrease the effects of gravity and participant weight on joints and soft tissue. The purpose of this study was to determine biomechanical gait factors such as length of time of the stride cycle, inversion vs. eversion of the foot, and point of contact by observing persons from the rear view at 40, 70, and As of 4-19-13 UG Symposium Presentation Abstracts 100% body weight on the Alter-g treadmill using Dartfish computer software. Our research questions for this project were: • From the rear view does inversion and eversion change from the three body weight changes on the Alter-G treadmill? • From the rear view does length of time of the stride cycle change from the three body weight changes on the Alter-G treadmill? • From the rear view does point of contact with the treadmill change from the three body weight changes on the Alter-G treadmill? The equipment used in this study was an Alter-G anti-gravity treadmill, timer, measuring tape, flashlights, heart rate monitors, video cameras, and Dartfish Software. The design protocol was tested on one person and included 3 minutes at each stage which were a walking warm-up, running warm-up, and a heart rate at 70% max 100, 70, 40% body weight. Results indicated that at a lower body weight stride cycle lengthened in time, inversion decreased, and point of contact changed from forefoot to toe. Godwin, Kyle Blake Lawrence, Eric Brettner, Adam Compton, Yuchen Liu Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Solar Autoclave for Rural Areas Developing areas around the world do not possess the technology to efficiently sterilize medical equipment. As a result, nurses and doctors at remote health clinics in these rural areas are continually challenged with the decision to operate with unsanitary equipment, risking the spread of infection, or to not operate at all. A solar autoclave provides an alternative solution to this problem. Using only solar radiation, a solar autoclave can provide remote health clinics with an inexpensive, efficient way to sterilize medical equipment. Our objective is to create a solar autoclave for use in rural areas that can be operated by any relatively inexperienced client. To begin, a parabolic trough was constructed to harness the irradiation from the sun and heat up a boiler located at the focal point of the trough. The water inside the boiler becomes pressurized, creating steam at temperatures no less than 121°C, which is eventually used to sterilize medical equipment. Interchangeable parts used in the design allow for various modifications and easy repairs. This allows for the autoclave to function with minimum maintenance. Goldtooth, Audrey Faculty mentor: Octaviana Trujillo, College of Social and Behavioral Sciences (SBS) History of Uranium Mining Impact on Traditional Navajo Lifeways This research examines factors affecting community members of the Navajo reservation living in or near areas of where there are abandoned uranium mines and the lack of awareness and education about them. The results indicate that there are numerous hazardous and life threatening anomalies affecting the livelihood of the Navajo population in these areas. It is apparent that most of the community members of the Navajo Western Agency are concerned whether these As of 4-19-13 UG Symposium Presentation Abstracts areas will ever be cleaned and/or properly shut down.

Gottschalk, Helen Madelyne Felsch, Kelsie Lawson Faculty mentor: Walter Vannette, College of Social and Behavioral Sciences (SBS) The Efficacy and Outcomes of ESL Programs in American Public Schools K-12 The poster will be focused on the teaching of the English language in American public schools K-12. We will not only be exploring ESL programs' effectiveness within the classroom, but also its policies, as well as the treatment of students. We will be defining for the public what we have found in our research in detail, addressing topics such as the effects that ESL training may have on a child’s cultural identity, and whether ESL is truly effective in aiding second-language students in English-dominated school systems and nation. In relation to the shortcomings of ESL classes, we will be exploring how ESL students are tested, what alternatives may exist, or improvements that may be made to programs across the country. Lastly, the teaching of ESL classes in public schools has a reputation for increasing multicultural sensitivity among teachers, and we will be looking for evidence of this as well.

Twelve students from multiple disciplinary backgrounds were selected to participate in the project. Students have researched various aspects of the ghetto before, during, and after Nazi occupation. Additionally, they have faced questions about translating their research into an interesting and educational exhibit. These questions include: whose voices to feature, what themes to showcase, and the practical constraints of the project. In this presentation, the student researchers will outline their findings and the process of creating a piece of public history about Bedzin. From multiple perspectives, including that of a survivor, a perpetrator, a student, and a historian, students will discuss the importance of their research and the challenges and successes of the project.

Groyer, Molly Faculty mentor: Rod Parnell, College of Engineering, Forestry and Natural Sciences (CEFNS) Project Assessment of Structures Certified by the Coconino County Sustainable Building Program As of 4-19-13 UG Symposium Presentation Abstracts The purpose of my internship was to analyze 9 structures that were certified by the Coconino County Sustainable Building Program (CCSBP) for energy and water savings and carbon dioxide emissions, as compared to a conventionally built structure. This was done to determine the efficiency of sustainable structures. Each assessment included collecting data from 9 residences certified from 2004-2011 in a face-to-face interview with a data tracking form. The report incorporates the general information about the structure, passive systems, home indoor air quality, water and electrical use with consideration of energy star and water conserving appliances, alternative and fuel use and a holistic narrative. The final report includes energy and water consumption graphs, a carbon dioxide emissions graph, table of specific building structure information, and a narrative from the residents. The assessment indicated that more active systems are not necessarily better because of the large energy consumption (even with solar panels, etc.). Also, I found that passive solar and gravity fed systems are excellent ways of reducing consumption without creating consumption. By creating an initial project assessment, future interns are able to compare their results to mine, and thereby provide the citizens and leaders of the county with valuable information about the practicality of sustainable building and ways that structures can meet the needs of residents and be eco-friendly. Grundy, Morgan Anna McCabe, Molly Ewbank, Ethan Goodman, Cecilia Garcia, Dr. Nora Dunbar Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) Improving College Freshman Retention and Enhancing Various Correlated Factors This research investigated factors related to retention of college freshman students attending Northern Arizona University. Social problem solving and resiliency were discovered as positively correlated factors to retention. The team designed an experimental and control educational training hypothesized to enhance problem solving ability and resiliency, thus improving retention. Results from a paired sample t-test indicate that participants who were randomly assigned to the experimental group had significantly lower negative problem orientations (.027) when faced with a problem than the control group. Guice, Kristina Faculty mentor: , College of Arts and Letters (CAL) The Language of Harry Potter In this presentation, I detail how I created my own corpus comprised of the seven Harry Potter books, then analyzed word frequencies of sixty-eight terms (thirty-four with positive connotations, such as ‘happy,’ ‘smile’, and ‘light;’ and thirty-four with negative connotations, such as ‘dark,’ ‘death,’ and ‘Voldemort;’) over the course of the series to determine how word frequencies affected the tone of the story. New York Times book reviews have described the series as getting “progressively darker,” and this analysis provides data on how that was achieved through the language used in the series. It also relates this change in tone to how it was portrayed in the movie adaptations of the books for further proof that the tone does, in fact, get darker and more ominous. As of 4-19-13 UG Symposium Presentation Abstracts Gutierrez, Estefania Lauren Sanchez Faculty mentor: Rebecca Maniglia, College of Social and Behavioral Sciences (SBS) RAPE Our presentation will be describing rape and the cons and mostly some of the pros that have come out of it as well. It gives a one-on-one interview with a man from jail who is in jail for rape and answered our questions.

Around the poster we also described different emotional quotes from victims of rape. Hagan, Tayler Jennie Long, Greg Robertson, Zach Klinefelter Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) The Effects of Audience Size on Nervousness This research assessed audience size and the effects it has on nervousness during a public speaking task on thirty students from undergraduates attending a small university in the Southwest region of the United States. Physiological, observe-report, and self-report methods of measurement were used to evaluate nervousness on participants in a public speaking task. The physiological and observational measurements were taken to assess change in nervousness. The public speaking task consisted of standing in a classroom setting in front of an audience while speaking about a familiar topic. Participants were placed in front of an audience size of 2, 4, or 6. Participants showed an overall increase in nervousness as audience size increased. Also, an increase from 2 to 4 was more substantial than an increase from 4 to 6. In conclusion, it was found that nervousness significantly increased as the negative accelerating power function grew.

Richard Coast, College of Engineering, Forestry and Natural Sciences (CEFNS) The Effect of Posture Change on Pulmonary Diffusing Capacity and Cardiac Output The aim of this study was to evaluate pulmonary diffusing capacity and cardiac output during steady state posture change. Ten healthy, non-smoking individuals of both sexes, ranging from 20 to 26 years of age, were selected to participate. Each subject was administered a pulmonary function test to ensure normal lung function. The participants then underwent rebreathing maneuvers in three different body positions: supine, sitting, and standing. Each rebreathing trial consisted of eight breaths at a rate of 33 breaths/minute . Subjects breathed in a gas mixture with known concentrations of acetylene, helium, and carbon monoxide which enabled the calculation of lung diffusing capacity as well as cardiac output. After data was collected, it was analyzed using a one-way repeated measures analysis of variance. Mean lung diffusing capacity for As of 4-19-13 UG Symposium Presentation Abstracts carbon monoxide (DLCO) in the supine position was 28.521 ± 5.633, in the seated position was 26.800 ± 5.239, and in the standing position was 25.429 ± 3.924. The data showed significant differences across postures (P<0.05). Further testing showed that there was a difference between standing and supine DLCO, but not between standing and sitting or sitting and supine. Similar results were seen for cardiac output. In conclusion, posture change from supine to standing effectively lowers the diffusing capacity of the lungs and their ability to extract oxygen. It also decreases cardiac output, indicating an effect of gravity on this variable as well.

Halvorsen, Tiffany Faculty mentor: Egbert Schwartz, Honors Program Prions: Proteinaceous Infectious Particles Prions are infectious agents of neurodegenerative diseases, unprecedented by other pathogens in their ability to alter protein structure and in their lack of any nucleic acids. Prions may be infectious, genetic, or sporadic in effect, but in all cases the prion attack arises from modification of the prion protein, a component of all regular mammalian cells, and causes complications in the Central Nervous System (CNS). Prions are responsible for some well-known diseases, such as scrapie of sheep, bovine spongiform encephalopathy of cattle, and Creutzfeldt-Jakob disease of humans. Dr. Stanley Prusiner of the University of California was awarded the Nobel Prize in Physiology and Medicine for his discovery of prions and the implications of his research, and his discoveries will be outlined and discussed as they pertain to current molecular biology and medicinal research. Hamilton, Sarah Faculty mentor: Egbert Schwartz, College of Engineering, Forestry and Natural Sciences (CEFNS) Comparison of Soil Microbial Communities of Native and Non-Native Grasses As of 4-19-13 UG Symposium Presentation Abstracts Fire danger in the desert Southwest is an issue made more hazardous by invasive species such as cheat grass which out compete sagebrush and other native species in the region. Fire from the dry and dense cheat grass can spread rapidly across landscapes killing sagebrush which is less dense and fire prone, and assisting in the reproduction of more cheat grass. Remediation efforts to reintroduce sagebrush species instead of cheat grass have not been very successful. Soil samples from military bases in the southwest were collected to compare the soil microbial communities around the roots of cheat grass and sage brush. In the lab of Dr. Schwartz I complete DNA extractions from these soil samples using DNA extraction kits that separate DNA from the cells within the soil samples. The products of these extractions are further analyzed to ensure DNA has indeed been isolated through will be used to compare and understand the soil microbial communities these of invasive and native species. Changes to the extraction protocol were required to successfully isolate the DNA from the samples which are poor in organic material. Further DNA sequencing and processing of new data is the next step to determine the differences in these soil communities. Insight into the effects of soil on the plants that grow there and vice versa may lead to better remediation efforts in the future. Hamilton, Susanna Faculty mentor: Karin Wadsack, College of Engineering, Forestry and Natural Sciences (CEFNS) Wind for Schools Children are the future. Giving children information about ways they can change the world is crucial. Northern Arizona University is currently working with Wind for Schools (WfS) to provide an education supplement to the rising generation (K-12 students). Wind for Schools has worked with over 1000 students and over 100 teachers to bring the topics of wind and energy into the classroom. This year, we have taken WfS an extra step further, and have included this program in special education classrooms. Bringing WfS into the special education classroom gives these students the same opportunity to be informed about climate change. WfS is continuing to support schools in an effort to install wind turbines which provide information about energy use, and can be a method of hands-on learning. Every child, specials needs or not, has the right to learn how to better the environment. WfS is attempting to do just that. Hamm, Deborah Faculty mentor: David Trilling, College of Engineering, Forestry and Natural Sciences (CEFNS) Searching for Kuiper Belt Objects using Ground-Based Telescopes Kuiper Belt Objects (KBOs) are icy bodies in the outer solar system and are remnants of the era of planet formation. In 2007 and 2008 we acquired data from the MMT and Magellan telescopes. We are currently searching this data for objects with the expected motion of KBOs. Specifically, we will measure the distribution of KBOs as a function of their size, distance, and orbit. Thus, this project will contribute to our understanding of how the Sun's family of planets and minor bodies originated and tell us more about how the solar system evolved to what we currently observe. As of 4-19-13 UG Symposium Presentation Abstracts Handel, Michael Arlyssa Watts, Kelly Curry, Kristyn Nielsen Faculty mentor: Brant Short, College of Social and Behavioral Sciences (SBS) Poverty in Contemporary America Our presentation will identify how popular culture has defined poverty by analyzing the film The Grapes of Wrath. We will present a case study for how The Grapes of Wrath has turned into an iconic statement for defining poverty. Although aged, we feel this film still holds value in what we view as poverty in contemporary America. Many of people live in poverty, and many more are just above the poverty line and have the potential to fall within it. There are many ways in which our society can relate to poverty through this film. We will look at the advantages and disadvantages of using this film to argue our case in defining poverty in contemporary America. Different opinions were formatted after The Grapes of Wrath was premiered. We will look at different critiques and references to compare the differences in each time period. Within the case study we will study closely and use different theories to describe the film as a rhetorical statement of poverty. Our goal is to not only define poverty in contemporary America but also to determine if The Grapes of Wrath will be used not only for entertainment in the future but allow the future to respond to poverty in a positive way. Hanf, Ian Faculty mentor: Kyle Paffett, College of Engineering, Forestry and Natural Sciences (CEFNS) Assessing Water Rights for National Forest Springs The Northern Arizona University Geology Department is currently conducting a study assessing the water rights status for all known springs on the Coconino and Kaibab National Forests. The purpose of this study will be to develop a complete listing of springs that are available for restoration projects based on their water rights status. My main task as an intern for this project was to inspect the water rights records housed at the two National Forest supervisors’ offices, as well as electronic records from the Arizona Department of Water Resources. Using the Arc Map geographic information system (GIS) program, I cross-referenced National Forest Service and Arizona Department of Water Resources records with Northern Arizona University springs data and helped to identify springs that are available for restoration based on their water rights status. Many springs were originally developed for the purpose of making a claim for a water right. Typical improvements include construction of diversion boxes, installing piping, creating storage, tanks and other structures, which may be removed or modified to improve a spring’s ecological condition if the water rights status allows. If water rights claims are valid, they may affect the process and prioritization for doing restoration at the spring. An updated springs database will be created with water rights claims information and a report indicating the status of the water right claim for each spring. Hanlon, Ashley Olivia Timothy, Jeanette Hernandez, Emacia Tsosie Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) As of 4-19-13 UG Symposium Presentation Abstracts Does Being Blue Mean Seeing Green? An Analysis of Depression and Jealousy Past studies have left a gap in collected information between jealousy, gender, and depression, leaving out important information on the distinction of the correlation between depression rate and jealousy rate. Our research will add to previous data involving gender differences in jealousy and depression. This research hopes to fill the gap by contributing to gender differences between depression and jealousy. 200 undergraduates at a small mountain college in the Southwest United States took a survey consisting of twenty-five questions related to hypothetical situations evoking feelings of jealousy. The participants also took Beck’s Depression Inventory measuring depression levels. The survey was given in a classroom setting in a packet including a demographics page. The study found that in men who were moderately to severely depressed correlated positively to higher amounts of jealousy. In women who were moderately to severely depressed there was also a positive correlation to higher jealousy rates. Males and females who were not depressed demonstrated less jealousy in the self-survey. Research proved that jealousy is an instinctual trait found in both men and women, differences originating in variations between men and women through evolution. Recommendations would include a modern exploration into gender, jealousy, and evolutionary theory and its correlation to depression.

Many of these archaeological methods involve intercropping or the use of As of 4-19-13 UG Symposium Presentation Abstracts biodiversity as an advantage to counteract climate and weather changes, so information will be presented about those topics as well. Information will also be presented about the current use of monoculture and its disadvantages and lack of sustainability. Harrison, Candace Faculty mentor: Michael Lerma, College of Social and Behavioral Sciences (SBS) Suicide This study investigates the concept building of the application of attachment patterns and suicidal rates among indigenous communities. Bowlby attachment theory described a connection between the infant and caregiver, which eventually impacts the child’s attachment to others. This been hypothesized that the attachment theory is related to suicide and depression in young adults when the attachment is to be preoccupied and avoidant. This paper furthers shows the connections linking the attachment theory, which means that many young adults in the indigenous community struggle with depression and are more likely to experience suicidal thoughts. There are suggestions for future research to help decrease depression and suicidal rates in Indigenous communities. Hart, Kendra Bruce Hungate, George Koch, Zhuoting Wu Faculty mentor: Bruce Hungate, College of Engineering, Forestry and Natural Sciences (CEFNS) The Response of Aboveground Net Primary Production to Climate Change in Northern Arizona Grasslands, 2002-2012 Changes in temperature and precipitation influence ecosystem structure and function, including species composition, plant growth, nutrient cycling, and water use. In the US Southwest, temperature and aridity are expected to increase during the current century. The present study built on a long-term experiment begun in 2002 that has used soil and vegetation transplants along an elevation gradient to examine how northern Arizona grassland communities respond to climate change treatments including 1) warming with increased precipitation, 2) warming with decreased precipitation, and 3) warming with ambient precipitation. The current study extended the analysis of the ANPP response an additional two years. ANPP was examined using high definition photography processed in Adobe Photoshop and related to direct measurements of aboveground biomass. Early results showed that warming initially increased aboveground net primary productivity (ANPP) due to increased nitrogen mineralization, but the magnitude of that increase declined over time. Harter, Elizabeth Faculty mentor: Chad Woodruff, College of Social and Behavioral Sciences (SBS) Self Other Discrimination of the Mirror Neuron System As of 4-19-13 UG Symposium Presentation Abstracts Mirror neurons a system of cortical neurons in the motor cortex that may contribute to our empathetic abilities. Empathy is defined by as the ability to understand and share the feelings of another (Davis, 1983). Mirror neurons are thought to be activated during imitation and acquisition of social skills, shared understanding, and observations of actions and emotions. This system is also activated during the planning and execution of an action. The ability to take on the perspective of others is a fundamental aspect of the empathetic response. The ability to differentiate between one’s own actions and emotions is an important part of this response. Dr. Woodruff et.al, 2011 hypothesized that mu suppression of mirror neuron activity differs between self and other, and that this differentiation is correlated with perspective taking abilities. This research looks at the difference in mu suppression when seeing one’s self perform an action versus seeing another person performing the same action. The importance of this research is to determine if there is a significant difference in mu suppression between self and other. Hatch, Hailey Devin Bierl, Maddison Savage Faculty mentor: John Houser, Brooke Edwards, College of Social and Behavioral Sciences (SBS) Analysis of Emotion Through a Colorful Perspective The purpose of this study was to determine the emotional effects of specific colors. The colors red, yellow, green, and blue were chosen as well as a clear control set to measure the influence of each color on happiness, anger, sadness, and anxiety levels. The participants were in residents of a small south western United States mountain community and were randomly assigned to a color and given a task to complete. Before and after the task an assessment of emotion was conducted. Red and yellow were found to cause the greatest increase in both anger and anxiety. Anxiety and sadness levels were maintained or decreased in the results of blue and green participants and happiness levels increased. In future studies variations of hue intensity may be taken into account. The affect of each color on productivity may also be an interesting variable. Hawkinson, Jeffrey Faculty mentor: Lauren Berutich Campus and Community Based Action Research Teams FYSeminar Program, University College, University College Action Research and Engaged Learning: Foodlink Community Gardens Fostering just and sustainable communities in northern Arizona through engaged learning, community partnerships, and action research A component of CRAFTS (Community Reengagement for Arizona Families, Transitions, and Sustainability), the Campus and Community Based Action Research Teams (CBARTs) create dynamic intergenerational hands on learning communities, bringing first year seminar students, returning undergraduates, masters students in the sustainable communities program and community partners into a collaborative relationship. As of 4-19-13 UG Symposium Presentation Abstracts There are over 10 Action Research Teams, a range of 250 to 500 undergraduate students and 20 SUS grad students participating both on and off campus in the areas of social, environmental, and economic justice issues. FYSeminar courses offered with an ARTs component exposes students to a unique pedagogical approach to hands-on, experiential learning of which content, skill set development, action research and student engagement are fruitfully intertwined and connected. This spring, each team is posed with the question, “What is Action Research?” and how does this work connect to community engagement, civic learning, and collaboration. Each poster will answer this question and share how Action Research has engaged students in hands-on experiential and civic engagement throughout the semester and year.

Propper, College of Engineering, Forestry and Natural Sciences (CEFNS) Evaluating naturalized populations of western mosquitofish, Gambusia affinis, in the Verde River watershed for biomarkers of endocrine disruption Invertebrate and vertebrate aquatic organisms exhibit a number of responses to xenobiotics, making them excellent bioindicators of environmental contamination. Rivers in the arid Southwest may be particularly vulnerable to chemical pollution as there is limited availability of surface water for dilution effects. Based on a prior study of benthic macroinvertebrate community structure in the Verde River watershed, Arizona, we identified five sites that may represent different pollution loads and a site that receives only spring-fed water. To determine whether these sites may also affect endocrine function in aquatic vertebrates, we used naturalized populations of western mosquitofish (Gambusia affinis) as a bioindicator for estrogenic or androgenic markers of pollution. There were no significant intrasex differences in anal fin lengths among all sites, suggesting that fish raised in these waters didn’t experience feminization or masculinization during development. However, body length in females and mass in males differed among sites, but these were not related to predicted pollution levels. The lack of differences in anal fin length suggests that there isn’t overt disruption of androgen activity in these sampled reaches. However, the differences in body size and mass may be related to complex biotic and abiotic interactions within the watershed. Our results suggest that water in the areas sampled may not affect androgenic activity in these fish. Furthermore, this study illustrates that within a watershed’s geographic microscales there are differences in population traits. These differences must be taken into account when trying to find correlations between pollution and physiological outcomes in natural populations. Heap, Alissa Faculty mentor: Melissa Santana, College of Arts and Letters (CAL) A Sustainable Passive Solar Home for a Veteran with PTSD Every year thousands of US soldiers come back from overseas, suffering from Post Traumatic Stress Disorder. Extreme paranoia and anxiety makes it hard to deal with normal situations As of 4-19-13 UG Symposium Presentation Abstracts without discomfort and stress. These veterans do so much for our country; they deserve to live in a home that helps ease these irregular discomforts. My research involves texts on PTSD and potential triggers and symptoms shown by different individuals with PTSD. I also conducted interviews with two local Psychologists that have experience with veterans and individuals affected by PTSD, and an interview with a close friend that served in Afghanistan and now suffers from PTSD. There are many similar symptoms that veterans with PTSD show: they constantly check windows and doors for someone coming or watching, they arrange themselves so they can have their backs to a corner or wall, they have trouble sleeping, they startle easily by sudden sound or visual motion, they are uncomfortable in unfamiliar, shadowy or busy places, etc. Although these symptoms seem to be very common for veterans with PTSD, they actually vary greatly depending on the individual and the origin of their PTSD. I implemented ‘green technology’ into my design, with the goal of creating a sustainable and eco-friendly home, as well as a therapeutic one. Sustainable living is achieved by a complex combination of systems, product choices, and practices. To make the greatest impact on energy savings, a combination of solar panels and a Passive Annual Heating System were implemented in the design.

While most focus is placed on conserving non-renewable resources, it is also important to place an emphasis on the sustainability of our lands soil. The Sustainable Landscape Maintenance Project places focus on conducting research and experimenting with methods in which toxic chemical pesticides and herbicides can be removed from the NAU grounds, without losing aesthetic appeal of the lawns. Spanning from the months of May 2012- October 2012, a team of two undergraduate students and myself conducted research and collected data on a variety of test and control plots located on the grounds of NAU campus. Using manual methods of weed removal, transect counting and turf quality measurements our team was able to make measurements of particular weed variety and quantity, aesthetic turf quality of lawns, and successful sustainable methods. At the end of our research period through data input and As of 4-19-13 UG Symposium Presentation Abstracts graphing, our team found that not only did our test plots aesthetically look more pleasing than the control plots; they also contained lower salinity levels. Also by increasing the length of the mower heights, allowing the lawns to grow a bit taller, weed suppression and turf quality greatly increased. In conclusion our team believes that by using sustainable methods such as over seeding with corn meal and gluten solution in the beginning of the spring, as well as increasing mower height, the NAU lawns can become more sustainable and chemical free. Herder, Denyse Faculty mentor: Michael Lerma, College of Social and Behavioral Sciences (SBS) Navajo Philosophy as a Protective Factor for Navajo Youth Against Risky Behaviors The prevalence of various risky behaviors among youth is not uncommon to indigenous peoples and their communities. Risky behaviors can range from, but are not limited to, substance abuse, violence, and engaging in sexual behaviors. Currently there is a movement among several other tribal communities and members of the research community to address the risky behaviors stated above through the incorporation of cultural knowledge and cultural involvement. The results of this research suggest that aspects of indigenous culture such as sense of belonging and involvement in cultural activities can be influential in deterring Native youth from engaging in risky behaviors. With this in mind, at the core of Navajo philosophy is the sacred idea of Hozho, which translates to harmony and beauty. Furthermore, through the methodological approach of concept building, one may perhaps see that Navajo philosophy may contain fundamental elements vital to the physical, emotional, spiritual, and psychological well-being of Native youth; thus providing Navajo youth with a protective factor against risky behaviors.

Gore & Associates are known to be a creative, technologically advanced enterprise producing highly reliable products. Gore® thrives to provide customers with the highest quality of products from medical products, electronics, to the one of a kind GORE®-TEX® fabrics. The primary objective of this project is to design and build a portable rain simulation chamber to demonstrate the waterproof and breathable garments effectiveness of GORE-TEX®. The portable rain room consists of three primary components: the base, water system, and room structure. The base is a 3' by 3' fabricated abs plastic, which contains all the water to be cycled and recycled through the water system. The water system produces various rain conditions from a light drizzle to a heavy driven rain with wind like conditions. The structure of the portable rain room is 3' by 3' by 8' room constructed from 80/20 aluminum square rods. The aluminum rods are useful because of the ability to place acrylic sheets in the slits to provide a view of the effectiveness of GORE®-TEX® fabrics. The Northern Arizona University portable rain room will provide W.L. Gore &Associates with an efficient way to display the effectiveness of GORE®-TEX® fabrics in various rain conditions at trade shows and demonstration events. Herrera, Luis Koll Christianson, Zheng Lian, Shaun Shultz Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Separation Connector Improvement for Orbital Sciences Corporation Orbital Sciences Corporation is an engineering design company that contracts in space vehicles and missile defense systems. Within each space vehicle or missile, there is a separation connector that allows the communication wires, located between each stage of the vehicle, to be safely disconnected. The current design of the separation connector uses many small pieces and requires an excessive pulling force to de-mate. Our team has designed the ‘Ball Bearing Detent’ separation connector to solve these problems. Based on the customer’s requirements and constraints, we developed a reliable connector that: leaves the male end of the connector unchanged, separates with a reasonable amount of force, is easy to manufacture, withstands military specification testing, and can de-mate under static and dynamic conditions. The Ball Bearing Detent design also reduced the number of internal components; thus, reducing the manufacturing process. The new design can statically de-mate with a pulling force less than 30 lbf and sustain dynamic shock loads up to 200 lbf. Lastly, the new design can achieve higher pull angles, which increases the chance of separation; thus, making it more reliable than its predecessor. Heyert, Alexanndra Faculty mentor: Jennifer Duis, College of Engineering, Forestry and Natural Sciences (CEFNS) Cell Phones in The Classroom With cell phones becoming more prevalent within the college community, an important question has arisen: how does cell phone use affect academic performance?

Hickman, Will Faculty mentor: Kevin Ketchner, College of Engineering, Forestry and Natural Sciences (CEFNS) Enumerating Sockeye Smolt in Chilkoot River, Haines, Alaska This study observed the migration of adult and juvenile Sockeye Salmon (Oncorhynchus nerka,) in the Chilkoot River system. Closely monitoring the strength of salmon runs is a cornerstone in managing the commercial fishing industry and preventing overfishing. Adult salmon are simply counted as they swam upstream through a single gate in the weir. Incline plane traps were used on the downstream side of the Chilkoot weir to gather juvenile salmon smolt. The traps were emptied twice a day and the numbers of fish were recorded for statistical analysis. A sample group of sockeye smolt from each counting period was taken aside to have some of their scales taken for observation. The length and mass of these fish were also recorded. Each week of the summer five hundred sockeye smolt were taken aside and dyed using Bismarck Brown. These fish were then released back upstream of the weir, in order to estimate the fraction of the total smolt run the traps were catching. Using simple statistics and the values from the mark-recapture experiment, it was estimated that approximately 2.6 million salmon smolt passed through the Chilkoot weir during the summer of 2012. The adult sockeye return to Chilkoot Lake reached 140,000 before the counting period ended, meaning that both the adult and juvenile salmon runs were strong, contributing to a strong commercial fishing season. Hill, Jennifer Faculty mentor: Kerri Quinn, Honors Program The Power of Faith in The Laramie Project In Moises Kaufman’s play, The Laramie Project, the members of the Tectonic Theater Project conduct interviews with citizens from the town of Laramie, Wyoming. In 1998, a young gay man named Matthew Sheppard is kidnapped, tied to a fence, tortured, and left to die by two of Laramie’s own sons. Differences in religious beliefs and practices sometimes separate a community, thus breeding hatred. But, religion also has a miraculous way of bringing people together and giving birth to hope. Hope is important in any community and can be a unifying factor both in times of great joy and times of great loss. In the wake of this tragedy, fear sets in and many members of the Laramie community find strength in religion. In The Laramie Project, religion creates conflict almost as much as it brings people together. Although religion gives justification to differing values and judgments, it allows individuals to connect to one another and is a tool that helps families heal during the grieving process, which ultimately enables the people of Laramie to overcome their struggle to find peace after Matthew’s death. As of 4-19-13 UG Symposium Presentation Abstracts Hill, Joseph Faculty mentor: Bryan McLaren, College of Engineering, Forestry and Natural Sciences (CEFNS) A Way to Clean by Being Green My objective for this project was to develop, author and implement a business plan that promotes the use of green cleaning products, especially with students. This project not only researches a hypothesis regarding the importance of green chemicals but it also investigates their positive effect on human health. In addition to these objectives, I gained experience in project management, policy navigation and community organization. I worked with the Office of Sustainability at Northern Arizona University to plan and develop methods of scanning and research, networking within the campus community, pitching ideas and striking discussions with top level stakeholders at the institutional level. Fostering a culture of sustainability is an overlying principle to this project. The results include a research scan of institutional green cleaning use and importance, informational fliers regarding green chemicals and an authored business plan. The information attained from this project has led me to believe that green chemicals promote human health and reduce sick days. The future of this project requires additional funding through either grants or scholarships in order to be put into action, and the Office of Sustainability should consider giving this project to future interns for that advancement. Hite, Addie Faculty mentor: Abbe King, College of Health and Human Services (CHHS) Controlling Pain in Postoperative Joint Replacement Patients Pain control in postoperative patients is a priority for nurses. Poor pain control can lead to hypertension, tachycardia, poor wound healing, delayed discharge, and transition to chronic pain. Current research suggests that pain control methods be chosen based on the type of procedure, the patient’s psychological status, and the patient’s comorbid conditions. Pain assessments should be conducted regularly to ensure that pain is identified, evaluated and managed appropriately. Scheduled oral (PO) pain medications and patient controlled analgesia (PCA) pumps provided better pain control than as needed (PRN) oral pain medications. Patients should be educated on the availability and efficacy of pain management strategies available prior to surgical procedures. Effective pain management plans should be put into place that recognize current evidence-based practice. Hochhalter, Christian J. Gruendike, Michaela Harbeck, Dawn Birdsell, Katy L. Parise, Julia M.

The third and second pandemics occurred during the 19th-20th and 14th-17th centuries, respectively. The first pandemic spread during the Justinian era of the 6th-8th centuries. DNA evidence firmly links Y. pestis as the cause of the two most recent pandemics but such evidence was missing for the Justinian plague. Recent genetic analysis of ancient DNA, extracted from skeletal remains of suspected plague victims from the Justinian era, confirmed the presence of Y. pestis DNA and identified its likely geographic origins. Central to the robustness of this confirmation was the use of synthetic positive controls in the genetic tests. Here we present the construction of the synthetic templates that were used as positive controls in the genetic tests that successfully linked Y. pestis as the cause of the Justinian plague.

Hottel, Sarah Faculty mentor: Nashelly Meneses, Stepehn Shuster, Russell Benford, College of Engineering, Forestry and Natural Sciences (CEFNS) Factors Influencing Metallic Blue Ladybird Beetle Abundance Heteropsylla cubana is a sap-sucking psyllid that attacks tangan-tangan (Leucaena leucocephala), an economically important tree. To control this psyllid, a natural predator, the metallic blue ladybird beetle (Curinus coeruleus), was introduced in different regions. Yet, few studies have been conducted to understand factors impacting beetle abundance within tangan-tangan habitats, which could influence their effectiveness as a control. I studied how geographic location, edge composition, time of day, and prey abundance affect beetle abundance. I recorded these factors and counted for five minutes the number of beetles present on each tree at seven randomly selected tangan-tangan edge habitats across the island of Saipan. I tested the effect of: geographic location and edge composition on beetle abundance using a Wilcoxon test, time of day on beetle abundance using a Mann-Whitney U Test and the effect of prey abundance on beetle abundance using a Spearman test. Beetle abundance was significantly affected by geographic location (N=130, X2 =65.45, P=0.0001), edge composition (N=150, X2 =62.8, P=0.0001), time of day (N=80 X2=18.02, P=0.0001) and prey abundance (N=310, r =0.45, As of 4-19-13 UG Symposium Presentation Abstracts P=0.0001). These results may inform more efficient management strategies for metallic blue ladybird beetle populations in tangan-tangan edge habitats. Huang, Lixiong Faculty mentor: Dean Smith, Franke College of Business (FCB) Desalination in San Diego San Diego's water supply is now depending on the water transfer from northern California and Colorado river, as it is near the ocean, desalination is becoming another good source of supply. In the article, I will introduce the current supply and demand in San Diego County area. And briefly introduce how desalination works, and find the costs of doing desalination projects. Compared with current costs will aid in deciding if the government or the private company will pay for and running the projects, and set up how the new market of desalination water should work. Hughes, Phoebe Faculty mentor: Anne Scott, Honors Program Postmodernism in Slaughterhouse-Five This paper looks at the Postmodernist features of the novel "Slaughterhouse-Five" by Kurt Vonnegut. Delving into specific examples from the text I look at the historical context of Vonnegut's writing as well as context found within the novel itself. And from this context I then look at how it translates into the Postmodernist style of writing and how it is relevant to modern American literature. Hulina, Chelsea Faculty mentor: Dean Smith, Franke College of Business (FCB) Fluoridation Program Cost/Benefit of Water Quality This presentation is a comprehensive study of the effects of fluoridation on consumer health. Fluoridation programs costs for implemented and studies on the benefits of preventing dental caries, tooth decay. In recent years the World Health Organization has raised concerns about the level of fluoride in consumer drinking water and the adverse health effects of consumption above the maximum contaminant level set by the Environmental Protection Agency. A contingent valuation will model the net present value of the fluoridation program. To account for additional consumer health costs first it must be established how much an average consumer is exposed to through other products such as toothpastes, and foodstuffs. Consideration of non-market values such as consumer health costs are reflected in contingent valuation.

The concept of physical attraction plays a major role both positively and negatively in the lives of human beings. What makes someone beautiful or attractive? There are many factors that contribute to this question, and although there are many reasons, attire itself can distort how an individual is perceived. With the majority of past research regarding this subject manner being outdated, the current study attempts to update previous studies. The participants were a selection of students from Northern Arizona University’s Research Methods in Psychology classes. They were instructed to look at a picture that depicted a female wearing a shirt that was either extremely conservative in its cut, mildly conservative in cut, or revealing in cut. Then, using a simple rating scale, the effect that clothing types have on the overall beauty of women was recorded by participants. It is hypothesized that the more provocative the clothing, the greater the attractiveness ratings. Humphries, Sarah Alex Messina, Carrie Bindschadler, Jered Kral, Eric Susak Faculty mentor: Constance DeVeraux, Honors Program AWP Writer's Conference Along with the four other participants, I will be describing my experience at the Boston AWP Writer's Conference. This will most likely include the conference as a whole, our stay in Boston, and my favorite session at the conference entitled "Video Games, Comics, and Fanfiction: Alternative Genres as Legitimate Literature." Hungate, Madalyn Faculty mentor: Matthew Anderson, College of Social and Behavioral Sciences (SBS) The Scent of Memory According to the Proustian Phenomenon, people often associate scent with memorable experiences; when they are later presented with that scent, it can rekindle emotions and memories associated with that event. These memories are typically highly emotional, aged, and vivid recollections of the individuals' sentimental experiences (Herz, 2000). To explore these effects, the researchers designed an experiment to test the effect scent has on the recall of factual information. The participants in this experiment were students enrolled in a developmental psychology course. Volunteers were informed with the details of the study, and they signed up for one of two experiment sessions. This experiment took place at the Northern Arizona University Cline Library. In this experiment the researchers measured the amount of recall by the participants through the administration of a quiz and comparing the results between groups. The researchers aim to find that recall is better among participants exposed to the same smell when learning the material and when being tested on it. The results of this experiment will possibly enhance study techniques for students. As of 4-19-13 UG Symposium Presentation Abstracts Hunt, Mackenzie Faculty mentor: Melissa Santana, College of Arts and Letters (CAL) Creating the Ultimate Boutique Hotel Experience in Revelstoke, BC The purpose of this project was to explore the necessary interior elements needed to create a luxury boutique hotel located in the hidden hills of Mount Mackenzie in Revelstoke, British Columbia, Canada. Because of the small, intimate qualities of the hotel and the desirable location, this space was designed to provide guests with an experience that is one of a kind. Inspired by the concept of sustainability, as well as the surrounding nature, and the beautiful views found in Revelstoke, BC, the design incorporated harmony, conformity, and tranquility throughout the hotel. Revelstoke's culture was embraced through bright colors, rich woods, and textured materials, reminding guests of the natural beauty that surrounds the areas. Because of the a scenic landscape, large windows were used to make the outdoor spaces the focal point in every room. Throughout the design, this establishment also used many features that have local ties to the community to create a one of a kind design. Research was conducted to determine what would make this space a unique experience. Interviews with boutique hotel mangers helped establish the criteria necessary to run a successful hotel and customer satisfaction reviews were read to ascertain what design features and amenities rating highly for overall guest experience. Case studies and scholarly journals were also used to understand the science behind natural daylighting, color theory, and sustainable building construction. With this information, the designer created a space that would integrate well into the Revelstoke landscape and culture while providing an exquisite boutique hotel experience which the clientele was looking for. Ing, Calvin Michael Bechtel, Ryan Mahar Faculty mentor: Joshua Hewes, College of Engineering, Forestry and Natural Sciences (CEFNS) American Society of Civil Engineers Student Competition Steel Bridge Design Team 1 The steel bridge design will be competing in the 2013 ASCE PSWC (Pacific Southwest Conference) Student Steel Bridge Competition. This competition gathers students from different universities and challenges them to create a model steel bridge with different constraints. Students are responsible for analyzing serviceability (vertical and lateral loading) of the bridge, testing material properties, fabricating the bridge, improving construction time and cost analysis of the bridge. This competition helps student gain a better understanding of the design process and real world application. The competition will be held at the University of Southern California (USC) on April 4-6, 2013. Results of the competition and analysis of possible improvements will be included in this presentation. Irving, Louis Marc Brewer, Sara Tackett, Brianna Welker Faculty mentor: Mathew Anderson, College of Social and Behavioral Sciences (SBS) As of 4-19-13 UG Symposium Presentation Abstracts Fear and Loathing in Psychology Majors Neuroticism is a personality trait characterized by low mood, anxiety, and emotional instability. Neuroticism is a major predictor of a variety of mental disorders including depression, panic disorders, and anxiety disorders. The purpose of the study is to determine if there is a difference in mean neuroticism trait scores between psychology and non-psychology majors. The information gathered from this study may be applied to awareness and treatment of mentalhealth issues in college students. Participants included over 100 psychology majors enrolled in a Psychology 302W course at Northern Arizona University and over 100 non-psychology majors recruited from the student union. The sample was composed of over 80 females and over 80 males ranging in age from 18 to 30. A quasi-experimental research design implementing a fivepoint Likert scale variation of the Eysenck Neuroticism Personality Inventory survey was used. We hypothesize that the findings will indicate that neuroticism scores will be significantly higher amongst psychology majors than non-psychology majors. These results will be congruent with previous findings that exposure to information regarding psychological disorders and instability is related to an increase in self-worry and other behaviors characteristic of neuroticism. Jackson, Randy Matt Garcia, Jeremy Mountain, Qian Tong, Hui Yao Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Design of Material Testing Fixture The goal of this project is to redesign a material testing fixture which is used to test a Magnetic Shape Memory alloy (MSM). The material is a composition of Nickel-Gallium-Manganese, which, when introduced to a magnetic field, can elongate by up to 6%. The current testing fixture has poor axial alignment, which applies eccentric loading on the specimen, ultimately leading to fatigue failure in the specimen. In order to measure the deformation of the specimen, there must be a least 12 mm of exposed specimen, which is observed by a camera. It is also crucial that the fixture not damage the specimen, or interfere with the applied magnetic field. The new fixture corrects this axial alignment by reducing the number of parts and using the testing rig for alignment. The new fixture is also capable of performing tension and compression tests, as the current fixture can only perform compression tests. This new fixture allows the specimens to be tested repeatedly without breaking, leading to more consistent results, and a more accurate model of the material. The collet style fixture that was designed as the solution ensures that the specimen will be axially aligned by applying equal force on all sides of the specimen during testing. A silicon sleeve was added to the fixture to compensate for any size variation in the specimen, as well as ensure that there is no damage to the specimen. Jacobson, Dane Michael Woodward Faculty mentor: Dana Ernst, College of Engineering, Forestry and Natural Sciences (CEFNS) The mathematics of the game Spinpossible As of 4-19-13 UG Symposium Presentation Abstracts The game Spinpossible is played on a 3 by 3 board of scrambled tiles numbered 1 to 9, each of which may be right-side-up or up-side-down. The objective of the game is to return the board to the standard configuration where tiles are arranged in numerical order and right-side-up. This is accomplished by a sequence of "spins", each of which rotates a rectangular region of the board by 180 degrees. The goal is to minimize the number of spins used. It turns out that the group generated by the set of spins allowed in Spinpossible is identical to the symmetry group of the 9 dimensional hyper-cube. A number of interesting results about Spinpossible have been shown either computationally or analytically. Using brute-force, Sutherland and Sutherland verified that every scrambled board can be solved in at most 9 moves. In this talk, we will relay our progress on finding a short proof of this fact. Jaramillo, Katelyn Faculty mentor: Gretchen Knudson Gee, College of Social and Behavioral Sciences (SBS) MNC's in the Developing World: India and China Many have argued whether or not MNCs have been beneficial to the developing world or whether they are just another way for the West to exploit the developing world. This paper will illustrate how MNCs have actually improved the quality of life for the people living in developing countries, their increase in standard of living, and how they have also increased the economic growth in the states, specifically focusing on the countries of China and India. The issue that this presentation will discuss is how MNCs have been and are beneficial to the developing world in improving the quality of life, increasing the standard of living, and increasing their economic wealth. This presentation will compare and contrast the findings and statistics that have been previously researched. The time period that will be specified in this presentation for illustrating the economic growth, increased standard of living, and quality of life will be from the 1978 to the present year. The quality of life will be measured by certain freedoms that are indicated in the Freedom House score and report. Standard of living will be measured by the Human Development Index (HDI), and the factors that go into the statistical findings of the HDI. Measuring economic growth we will look at the increase in the amount of goods and services produced by each of these countries over time or their GDP. Jarpe, Joel Kaitlyn Patterson, Adam Rogers, Tyler Lee Faculty mentor: Julie Heynssens, College of Engineering, Forestry and Natural Sciences (CEFNS) Geological Data Transmitter This project is to upgrade field geological equipment with wireless data transmission capabilities. At the moment, these field probes store all data they have obtained in removable memory drives and these drives must be obtained by a user from time to time to read the data. The system we are creating will allow for wireless data transmission, this will allow all the data to be transmitted to a computer at another location and prevent the need for a person to have to drive out to these remote locations and physically obtain the data. As of 4-19-13 UG Symposium Presentation Abstracts Jeffrey, Daliza Faculty mentor: George Gumerman, Honors Program American Food Deserts and its Threat to Minorities The term “food deserts” may be foreign to many, but it is reality most Americans face every day. A food desert is defined as an area where there is little to no accessibility to healthy foods and an overwhelming presence of food insecurity among inhabitants. These areas have created certain barriers (i.e. a lack of transportation, a low quantity of chain supermarkets, and/or a high cost of living) that prevent people from having a nutritious diet. The lack of nutritious foods in metropolitan cities causes the creation of food deserts, which negatively affects the physical health, the financial success, and the identity of the minorities in these cities. Minorities make up a large percentage of the population in food deserts. The obesity epidemic in America, which minorities and low income households are more likely to be victim of, can be linked to the ease of accessibility of fast food and junk food versus chain supermarkets in a food desert. Food insecurity in food deserts has the indirect costs of low high school graduation rates, high unemployment, and poverty. Food is one of the main symbols that identify a culture. With the lack of nutritious or diverse foods, traditional dishes from native lands must adapt to the new low quality foods present in food deserts. Jenkins, Darbi Ciera Lund and Kayla Frosaker Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) Effect of Personality Type and Greek Affiliation on Substance Abuse The purpose of this study was to observe if individual personality types are related to substance abuse habits that people may possess. It was speculated that Greek organization affiliates would be subjected to drugs and alcohol, which therefore might perpetuate substance abuse habits among members. It was further hypothesized that individuals with more extroverted personality characteristics including those in Greek organizations would be more likely to have substance abuse problems, as opposed to those who embody introvert personality characteristics, and, specifically, display a higher rate of alcohol abuse tendencies. There were 75 participants enrolled in the Research Methods courses from which samples were drawn. Of the participants, 61 scored high in extroversion, labeling those with lower scores as having introvert personality types. Of the 15 who reported high levels of alcohol use, 13 of them also had a high score in extroversion. In contrast, 14 of the 75 scored low in extroversion, indicating introversion qualities reported having alcohol abuse tendencies. Furthermore, we support our hypothesis. Jensen, Deidra Faculty mentor: Kiisa Nishikawa, College of Engineering, Forestry and Natural Sciences (CEFNS) The Effects of Demembranation on Passive Force in Skeletal Muscle As of 4-19-13 UG Symposium Presentation Abstracts Demembranation is an important method used in muscle physiology and research. Titin (Connectin) is a large spring-like protein present in muscles that is responsible for passive force when a muscle is stretched. Demembranation (skinning) removes the muscle’s membrane and allows other molecules to easily diffuse into the muscle. Previous studies suggest that the skinning procedure could degrade titin and affect the passive force of a muscle. Optimizing the skinning protocol could effectively improve how we learn about titin and its different components in active muscle. In this study, I measured the passive force from mouse soleus muscles at different lengths before and after the muscle was skinned. First, passive force is measured in physiological Kreb’s solution. Then muscles are submerged into a relaxing solution (to prevent rigor mortis) for an hour, followed by a skinning solution for 24 hrs. After the 24hr skinning period, muscles were placed into another relaxing solution. Again passive force data was collected. Both sets of passive tension data was analyzed and compared to determine if there was any significant effect of skinning on passive tension. The results from my experiment showed there was a decrease in passive force after the muscles were skinned. This suggests that the skinning solution does affect muscle elasticity and may have degraded some of the titin protein. This work will improve how we perform and understand how skinning methods affects muscle proteins such as titin. Jimenez, Yordano Alice C. Gibb, Ian MacDonald Faculty mentor: Alice Gibb, College of Engineering, Forestry and Natural Sciences (CEFNS) Do California halibut develop different escape responses between their larval and adult life stages? Flatfishes (Pleuronectiformes) are an unusual group of fish that, as adults, have both eyes on one side of their head; however, as larval fish they are bilaterally symmetrical. Because of this unusual, asymmetrical adult anatomy and their commercial importance as a food fish, this group is of interest to biologists from various fields. We will investigate and describe the behavioral development of the escape response (i.e., the ability to evade potential predators) in California halibut (Pleuoronectidae) and to determine if behavioral patterns suggest changes in the neural pathways that triggers the escape response occur as fish change from symmetrical (as larvae) to asymmetrical (as adults) anatomy. We will analyze high-speed recordings of California halibut escape responses to identify any changes in escape response behavior that may correspond to particular life stages. We hypothesize that pre-metamorphosed halibut perform “typical” (i.e., similar to those seen in other fishes) C-start escape responses, then transition to S-start escape responses after metamorphosis. To determine potential changes in the neural pathway that controls the escape response, we will analyze high-speed footage to determine the fish’s response time to a stimulus. Different neural pathways are known to have different response times; thus, by determining response times to stimuli in different life stages we can extrapolate whether halibut exhibit any neuroanatomical changes throughout different life stages. Our predictions are based on the observation that halibut larvae are free-swimming and encounter different forces of resistance from when they become benthic, cryptic adults and must therefore develop behavioral and neuroanatomical adaptations for effective predator evasion.

Students’ backgrounds range from (art) history majors to museum studies and interior design. Currently, the historical item is located in a small hallway in Babbitt with no real presence and a new space for the artifact was secured a small, out of the way alcove on the second floor of the Union. The problems the group aimed to solve was twofold: (a) how can the Berlin Wall be relocated to its new location while giving it a strong presence and appeal at the university and (b) how can the history and significance of this piece be best represented in a 33’ long alcove? Together the group used their skills to create a collaborative and cohesive idea. Being from different backgrounds they educated one another on how their individual disciples and specialties would contribute to this project. Members of the group teamed up to either do historical and fact-finding research while others investigated the design and construction process. Meeting bimonthly the group then came up with a solution that not only incorporated the initial goals but really created a space the university can be proud of.

Johnson, Lauren Christopher Gelety, Melissa Birkett Faculty mentor: Melissa Birkett, College of Social and Behavioral Sciences (SBS) Sex Differences in Immune Response to a Social Stressor Secretory immunoglobulin A (sIgA) is an immune antibody in which levels of sIgA are associated with stress reactivity. The sIgA response to stress can be measured using noninvasive salivary measurement techniques. This study seeks to evaluate sex differences in immune response to acute stressors and draws correlations between immune and stress response. To examine the effects of sex on immune response to a social stressor, males and females completed the Trier Social Stress Test (TSST). The TSST included speech preparation, speech performance, and mathematics periods. Measures of self-reported anxiety, physiological As of 4-19-13 UG Symposium Presentation Abstracts reactivity, and sIgA revealed significant increases in sIgA immediately following stressor exposure. The TSST elicited significant increases in state anxiety and increase in skin conductance throughout the stressor. Altogether, the results of this research suggest that significant sex differences exist in immune response to the TSST. Jones, Burrell Faculty mentor: Michael Lerma, College of Social and Behavioral Sciences (SBS) Power of Language that Influences the Significance of Water in the Soutwest The premise of this research is based on the struggle about water rights in the southwest. More importantly, the contrasting ideas between Indigenous and American worldview in settling Navajo and Hopi water rights in Arizona. These ideas stem from Indigenous language and conflicts with mainstream cultural perceptions on water. Therefore, the idea from language of both cultures dispute in resolving the Little Colorado River Settlement Act. This research examines the concept of using language or the discourse of language in settling Navajo and Hopi water rights. Jones, LouGene Faculty mentor: Michael J. Falk, College of Engineering, Forestry and Natural Sciences (CEFNS) Hyperplane Arrangments and Linear Syzygies The purpose of my research is exploring hyperplane arrangements. More specifically, my hope was to find new examples of hyperplane arrangements such that their master functions form a linear syzygy. A polynomial master function is a multivariate polynomial that splits into linear factors, where multiplicity may occur. These linear factors define hyperplanes of the arrangement. A linear syzygy is a linear relation among polynomial master functions. Through my investigations, I've found that these arrangements can be derived from graphs. From these graphs I've been trying to construct these linear syzygies using combinatorics. The existence of such a linear syzygy has deep implications for geometric, topological, algebraic, and combinatorial objects associated with the arrangement.

Kay, Robert Kian Bidanjiri, Tasha Harder Faculty mentor: Stan Lindstedt, College of Engineering, Forestry and Natural Sciences (CEFNS) Examining the Effects of Titin in Animal Locomotion Energetics The energetic cost of locomotion is the single most costly energetic activity in mammals. For that reason, it is not surprising that animals, and their muscles, have experienced thousands of years of evolutionary pressure to minimize the energy cost of movement. The consequence of strong and unrelenting selection is that animals employ a diversity of structural and functional characteristics to move about. For that reason, one might expect that any change in muscle properties might result in a measurable increase in the “cost of locomotion”. In particular, the giant protein “titin” is thought to play a major role in the storage and recovery of elastic recoil potential energy. The mdm mutant mouse has been a model system for studying muscular dystrophy. These animals have a defect in their titin molecule that could also impact their cost of locomotion. It is the hypothesis of this study that if titin cannot function as a normal muscle “spring” the cost of locomotion will increase. To test this hypothesis we measured oxygen As of 4-19-13 UG Symposium Presentation Abstracts consumption of normal and mutant mice while running on a motor driven treadmill. Our preliminary results suggest that these animals require more energy than predicted (increased cost of locomotion) relative to mice with intact titin. Keeling, Aleigha Faculty mentor: George Gumerman, Honors Program Understanding Rising Food Insecurity in the New Millennium In 2009, the United States hit a fourteen-year record for food insecurity with 15% of households struggling to secure enough food for their families. As of 2011, that number had not changed. In a country known for its prosperity, this high number is both shocking and appalling. In order to better understand this problem, I propose that one must look into recent changes in the economy. In my presentation, I present the issue of food insecurity as one of economic inequality, emphasizing how the relationship between stagnant wages and rising food prices has led to an increased struggle on the families of the United States.

Kimble, Leigh Faculty mentor: Cassandra Dakan, Honors Program The Role of Literature in Nazi Germany I analyze the role that literature played in Nazi Germany in swaying the thinking of a logical people into believing the backward political ideology of the Nazi party. Drawn from my research As of 4-19-13 UG Symposium Presentation Abstracts project from Honors 190 this previous semester, I will argue that literature played a crucial and large role in this significant transition in history. My research spans across three phases of the National Socialist takeover until it dominated all German life. First is exactly how the Nazis first infiltrated literature in order to make the German people accustomed to Nazi ideology, then, how the Nazis manipulated and reinterpreted existing literature to persuade the German people into siding with Nazi beliefs even further. Finally, the Nazis took this accepted presence in literature and translated this domination into all aspects of German life, resulting in the Third Reich. The Nazis used existing popular literature, placed taboos on other literature and distributed their own literature throughout the rise and height of their power. These actions and the role literature played in all of this are crucial, because literature signifies the social reconstruction that the Nazis first had to accomplish if they were to gain power. Without literature and the societal importance it played, the Nazi party would not have reached the power and the trust of the German people that it did.

King, Dakota Faculty mentor: Anne Scott, Honors Program Binary Thinking: Humanity's Construction Since the beginning of human existence, we have attempted to turn our world of many components into a series of binary states of mind; male or female, peasant or ruler, with us or with them. Rather than deviating from such a simple minded view, humanity as a whole has turned to using this Boolean thinking in every aspect of life, from education to moral judgment. However, in nature and at the depths of humanity it is never as simple as hot or cold or happy or sad. If we are to progress as a human race, we must pull away from such either/or reasoning, easy as it is, and develop into a pluralist system, allowing for many other options from what is immediately thought of. Rather than “Is your skin color white?” we can ask “From where do your forefathers come from?” Instead of “Are my actions morally right or wrong?” we can question “What consequences will my actions hold?” This way of thinking would not only destroy all social norms and rid our society of discrimination; it is how nature and the world truly work. King, Marlee Celena Leland, Rolando Yazzie, Desyre Diaz Faculty mentor: Matthew Anderson, College of Social and Behavioral Sciences (SBS) As of 4-19-13 UG Symposium Presentation Abstracts What's Hot - Taken or Not? The feeling of attraction is arguably one of the most salient aspects of the mate selection process. Attraction is a common experience which affects the vast majority of people world-around, and for this reason it is the topic of countless research studies. These studies explore the many different facets of attraction, including the effect of relationship status on perceived attractiveness (O’Hagen, Johnson, Lardi, & Keenan, 2003), which was the source of inspiration for the current study. We hypothesize that an individual’s relationship status does have an effect on how attractive others find them to be. To test this, the researchers gathered a sample of college students (male and female) for an experiment which manipulated relationship status of an individual using two separate vignette descriptions, and measured participants’ attraction to that individual using a brief questionnaire. While the hypothesis is nondirectional, based on the results of previous research the team expects to find a somewhat lower level of attraction to the individual described as in a relationship compared to the individual described as single. Such findings would be of interest for future research due to the sociocultural implications; it would open new perspectives on what makes people attractive and why, as well as raise even more questions about the practice of mate poaching. Kinser, Rebeca Valerie Gibbs Faculty mentor: Nadine Barlow, College of Engineering, Forestry and Natural Sciences (CEFNS) A New Database of Craters 5-km-Diameter and Larger for the Moon: Wetern Nearside We are using the Lunar Reconnaissance Orbiter Wide Angle Camera (WAC) imagery (100 m/pixel resolution) to identify and classify all impact craters ≥5-km-diameter in the 45°N-45°S 270°-360°E region of the lunar nearside. Where available, LRO Narrow Angle Camera (NAC, 0.5 m/pixel resolution) imagery is used to help classify crater morphology. We are using the crater counting routine in the JMars for the Moon software package to measure crater diameters and determine central coordinates of each crater. We also use the JMars for the Moon software to obtain topographical profiles of the craters in our study areas using the LRO Lunar Orbiter Laser Altimeter (LOLA) data. To date, we have cataloged 1114 craters within the study region. The area contains both mare materials (with formation ages ~3.0-3.7 x 10^9 yrs) and highlands materials (dating to ~3.8-4.4 x 10^9 yrs), allowing us to investigate the role of terrain differences on crater morphometry. To date, we have completed depth measurements of 989 craters in the study region. We have divided the craters into those occurring on mare versus highlands materials and computed depth-diameter (d/D) ratios for each. A rough analysis of the simple to complex transition diameter for both the mare and highlands regions within our study area has also been completed from the information gained from these ratios. We have also completed ejecta and inferior morphology analysis for 379 craters both in highlands and the mare region for the Northwestern section. Kish, Nathan Daniel Andenmatten, Brandon Hoffman, Chris Simpson, Pengfei Wu As of 4-19-13 UG Symposium Presentation Abstracts Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Nestlé Purina Dryer Efficiency Improvements Nestlé Purina has a facility in Flagstaff, AZ that produces pet food. The final product is dried to reduce moisture content using four steam dryers. The purpose of this project is to diagnose and solve the problems dryer 3 has been experiencing using mechanical engineering design. Constraints include: reducing moisture content to below 12%, increased overall efficiency and safe operation for the facility personnel. After investigation of the plant systems, our team determined that condensation of steam in the heat exchanger coils leads to reduced heat transfer between steam and air. After reviewing dryer design from Nestlé Purina facilities, we proposed a new dryer design that replaces steam as the heat source to a natural gas fire. The team also found that cost savings in removing the transmission losses between the plant boilers and the dryers are significant. The proposed new design replaces steam heat exchangers with individual natural gas heaters. By making these changes in design, the team hopes to achieve 20% improvements in efficiency, which translates to savings of $38,000 per year. The team estimated a payback period of 2 years for the additional investment required for modifications. Klaas, Danielle Faculty mentor: Peter Fulé, College of Engineering, Forestry and Natural Sciences (CEFNS) Climate Sensitivity of Co-Occuring Species on the North Rim of the Grand Canyon My project investigates how different tree species respond to different climatic conditions in a unique protected area, the Grand Canyon. Only very limited data is available for higher-elevation forests of the park, but these ecosystems are vulnerable to climate change impacts. The information gained from this project is crucial in understanding the relationship between tree growth and climate change across different topographic positions for key tree species: Abies concolor, Pinus ponderosa, Populus tremuloides, and Picea species. Plots have been established on the North Rim of the Grand Canyon varying in elevation, slope, aspect, and slope position, allowing us to compare the sensitivity of rings for topographic position. Tree cores were collected, dried, glued to mounts, and sanded until their cells are visible under magnification. The cores are then cross-dated, measured, and analyzed to determine how tree growth sensitivity differs across different topographic positions and how sensitivity differs among co-located species. The relationship between climate and tree growth is crucial to management decisions on the North Rim of the Grand Canyon. The results of my study will also allow predictions to be made about which species and topographic positions are most vulnerable to drought effects such as insect attack, wildfire, or cavitation, and to provide guidance to National Park managers that will be useful as they plan fire and wildlife habitat management. Klein, Jerimiah Faculty mentor: Adam Hoffman, Honors Program Zealot in Combat As of 4-19-13 UG Symposium Presentation Abstracts This is a drawing made of an alien in the middle of combat on a foreign planet, with battle ships in the skies in the background. This drawing took a couple of weeks to complete in my art class at Sandra Day O’Connor. The art itself meant a lot to me at the time because it took a lot of my time and attention to detail, as well as it had a lot of deeper meaning with what I was going through at the time. Klein, Lucas Faculty mentor: James Swift, College of Engineering, Forestry and Natural Sciences (CEFNS) The Physics of a Violin String My own experience with the violin led me to research and mathematically map the physical movement of a violin string as a bow is drawn across it. Musicians and listeners alike take advantage of the different qualities in sounds that bowed and plucked string instruments make. The different tones we hear are determined by the frequency of vibration of the string. Then, why do plucked A-strings sound different from bowed A-strings? The answer is in the solution to the wave equation. As the bow begins to move along the string, its pressure creates a static friction that allows the string to stick to the bow and be pulled a small distance. At a certain distance from its equilibrium position, the friction turns into kinetic and the string begins to slip backward. These cycles of stick and slip are called Helmholtz motion. The cycles have the same period as the vibration of the string, and also as the wave we hear propagating through the air. At the nut at the end of the fingerboard and at the bridge, the string cannot vibrate. Therefore, our function, U(x,t) (the distance of the string away from its equilibrium position at any length x and time t), is equal to zero at these x-values. These and other boundary and initial conditions can be used to satisfy the wave equation.

Krementz, Dana Faculty mentor: Micheal Lerma, College of Social and Behavioral Sciences (SBS) Disability, Gender, and Indigenous Status; Assessment of and Proposals for Overcoming Intersectional Barriers to Public Health Service Despite Indian Health Services claiming a goal to providing comprehensive, accessible and culturally appropriate public health services to all American Indian and Alaska Natives since As of 4-19-13 UG Symposium Presentation Abstracts 1787, these communities suffer from some of the worst health disparities in the world. According to the National Indian Health Board, when compared to other groups American Indians are 650% more likely to die from tuberculosis, 318% more likely to die from diabetes and 204% more likely to suffer accidental deaths. What’s even more disheartening than these severe health disparities is the fact that they are all preventable. Public health measures are vital to combating and preventing these causes of deaths, yet they have all but failed on the parts of these communities. However, it is not these programs that fail, rather it is the physical and social barriers that prevent people from initially accessing these services that make them ineffective. These exclusions are not universal and tend to be exacerbated in the populations that need them most. Indigenous populations are already at disadvantaged by having to rely on the notoriously underfunded IHS but when different forms of oppression intersect, barriers to public health services are dangerously compounded and become virtually insurmountable. Living in the cross roads of racial, gendered, and ability based oppressions Native Women with Disabilities (NWD) face some of the most barriers to public health services. This paper attempts to outline common barriers to public health services encountered by NWD as well as to propose methods for determining and applying solutions. Kruse, Samantha Faculty mentor: Kerri Quinn, Honors Program Female Sex-Positivity For my presentation, I would like to present my project for my HON291 class, in which we are supposed to “Pay it Forward” through writing. The goal of my project is to promote sexpositivity. In a nutshell, sex-positivity is giving people the empowerment to make their own decisions regarding their sexuality without being judged for it. I want to focus on the female side because it is a bit closer to my own heart, and while I care about every aspect of human sexuality, focusing on the female side will narrow my project to a manageable size. I understand that many people are tough nuts to crack, and they may never change their opinions regarding female sexuality, but if I help even one person avoid the mental strain of society’s judgment, I will feel like I accomplished my goal. The project will be in two parts. The first part will be a blog, where I will do biweekly-weekly posts about some part of positive female sexuality. The second part is that I plan to present at a junior high or high school, either in the form of a small assembly or to individual classes. For the symposium, I will present what I have learned and how the school presentations went in a PowerPoint. Kutsop, Nicholas David Trilling Faculty mentor: David Trilling, College of Engineering, Forestry and Natural Sciences (CEFNS) Thermal Inertia of Uranian Satellites Surfaces The moons of Uranus enter into Uranus' shadow, called an eclipse, only every 42 years due to Uranus' high obliquity, or angle of axis of rotation. While the moons enter the shadow of Uranus they are still visible from Earth. When these moons are eclipsed the temperature on them decreases from when they were in sunlight. Using infrared telescopes we can analyze this As of 4-19-13 UG Symposium Presentation Abstracts temperature change. The moons of Uranus have no atmosphere and so the surface is in thermal equilibrium with the sun's radiation and therefore has a predictable and calculable temperature. From this analysis we can make claims about the thermal inertia properties of the surface. We examined the two largest moons of Uranus, Oberon and Titania. The data was taken using the Thermal-Region Camera Spectrograph at Gemini South in Chile in July of 2008.

Lamy, Tyler Brian Western and Andrea Heppner Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) How Fear Affects Memory Recall In fearful situations, having a clear memory of critical details can be very important. Instead of the direct relationship between fear and recall, most previous research focuses on fear memories or negative emotions. The effect of fear on memory recall included students of age 18-27 years old (mostly European American females) who were enrolled in the Research Methods (PSY 302W) course at Northern Arizona University. An experimental design was completed in which the participants were given a word list to memorize and then were required to finish a computer maze. Moreover, the maze given to the experimental group produced fear in the participants. The expected outcome is that those who were scared during the experiment will remember fewer words from the list than the control group. The results would suggest that participants who are fearful recall significantly less words than those who are not fearful. Landis, Margaret Faculty mentor: Nadine Barlow, College of Engineering, Forestry and Natural Sciences (CEFNS) Impact Crater Analysis of Southcentral Arabia Terra, Mars As of 4-19-13 UG Symposium Presentation Abstracts Impact crater morphologies, ages, and locations give significant insight into the history of near surface and surficial ices in a particular region. This Honors thesis presents results from an impact crater analysis of the south-central region of Arabia Terra, Mars. Arabia Terra has shown signs of water enrichment and a significant resurfacing event through other studies, and we have confined the timing and locations of near surface volatiles by tracking morphologies that occur in ice-rich target material.

Landis, Margaret Faculty mentor: Kevin Ketchner, Honors Program American Women in the Sherlock Holmes Short Stories The character of Sherlock Holmes has been persistent in the popular imagination since the late 19th century. While Holmes uses modern methods of thinking and collecting evidence to support his deductions, his attitudes often represent a more traditional British social viewpoint. The balance between imperialistic British themes, particularly with respect to American female characters, and interesting puzzles makes Holmes and enduring character and relevant today. These elements will be discussed in the context of A Scandal in Bohemia and The Adventure of the Dancing Men. Lane, Taylor James Maxcy Faculty mentor: Marianne Nielsen, College of Social and Behavioral Sciences (SBS) Women and Crime This presentation illustrates the gender gap between male and female offending rates as it relates to the criminal justice system.

Through the analysis of homicide, child abuse, serial murder, and theft, conclusions are drawn regarding female offending. Lassiter, Linda David K. Elliott Faculty mentor: David Elliott, College of Engineering, Forestry and Natural Sciences (CEFNS) As of 4-19-13 UG Symposium Presentation Abstracts An Investigation of Eurypterid Arthropods as Predators on Early Vertebrates Eurypterids were marine arthropods that existed from the Ordovician through the Permian periods (450-260 million years ago). The fact that eurypterids and armored early vertebrates (agnathans) are often found in the same strata has led to the speculation that eurypterids were predators on agnathans. Direct fossil evidence is rare because successful predation generally results in the destruction of hard parts. However, an Early Devonian agnathan, (italics)Lechriaspis patula, was recently described, exhibiting three aligned punctures in the dorsal armor, presumably from predation. It was deduced that the most likely predator was the pterygotid eurypterid (italics)Jaekelopterus howelli. Despite this evidence there is still a question as to whether eurypterid pincers could have generated enough force to pierce agnathan armor. A recent study calculated the force needed to puncture non-bony material by the pterygotid genus (italics)Acutiramus. The unique configuration of the Acutiramus pincer led to the conclusion that it could not have penetrated the armor of an agnathan without failure. Additionally, the experimental data suggests that a different configuration of the pincer could enable penetration of bony armor. A second question is how frequently pterygotid eurypterids (that have grasping pincers) co-occur with agnathans in the fossil record. Analysis of the distribution of these two groups of organisms shows that they consistently co-occur. We therefore conclude that there is a strong likelihood that pterygotid eurypterids were capable and frequent predators of agnathans. Lauren, Campbell Nick Schafer, Michael Donelson, Aaron Hansen, Erin Grenko Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Quick Change Electrical Connection This project works with the defense company Raytheon to design a self-aligning, simplyinstalled quick change electrical connection for one of Raytheon’s current missile designs. The current electrical connection design does not allow for a simple and effective connection between the nose and body of the missile. As the design stands, the electrical connection must be manually connected, which is both inefficient and does not assure that the connection is properly made. Our team has been given the opportunity to be a part of the Raytheon Company by creating a design that quickly mates the electrical connection assembly. This includes electronic connections that self-align and provide a secure contact of that connection for all environmental factors the weapon will experience in normal conditions. The current design is easily implemented, field replaceable, and is able to be mated by one person. It contains two selfaligning areas that allow for the missile to be mated even with a misalignment. It is also made using a material that can resist the corrosive environment. With the implementation of our design we believe that Raytheon will be able to quickly mate and align the two parts of their missile system under the environmental conditions. Lavarias, Mitchell Faculty mentor: Matthew Gage, College of Engineering, Forestry and Natural Sciences (CEFNS) As of 4-19-13 UG Symposium Presentation Abstracts Ionic Charge and the Hofmeister Series Effects on Model Intrinsically Disordered Proteins The structure of a protein is important as it affects how proteins function because binding is highly controlled by shape and size of the ligand. The structure of globular proteins depends on the formation of a hydrophobic core and stabilizing ionic charges. Recently, a new class of protein was discovered called intrinsically disordered proteins (IDPs) that lack a stable structure under physiological conditions until they bind to a cellular target. Since IDPs have a large amount of charged amino acids but no hydrophobic core, we predict that IDPs secondary structure will be affected by the ionic strength of a solution. As the crowded cellular environment has a high ionic strength, this could be part of the reason that IDPs are able to change structure. Various salts from the Hofmeister series (KCl, NH4Cl, MgCl2, (NH4)2SO4, and MgSO4) are added in varying ionic strength to the model IDP FlgM. The secondary structure of the protein is measured using Circular Dichroism (CD). Preliminary results have shown that most salts help the IDP FlgM form more alpha-helical content, which increases over time. The information developed through this study will provide new insights into why IDPs change their structure and could provide new understanding of the altered protein structures that lead to diseases such as cancer and Alzheimer’s disease. Ledgerwood, Madison Frankie Beesley Faculty mentor: Lauren Berutich Campus and Community Based Action Research Teams FYSeminar Program, University College, University College Action Research and Engaged Learning: WACBAT Fostering just and sustainable communities in northern Arizona through engaged learning, community partnerships, and action research A component of CRAFTS (Community Reengagement for Arizona Families, Transitions, and Sustainability), the Campus and Community Based Action Research Teams (CBARTs) create dynamic intergenerational hands on learning communities, bringing first year seminar students, returning undergraduates, masters students in the sustainable communities program and community partners into a collaborative relationship. There are over 10 Action Research Teams, a range of 250 to 500 undergraduate students and 20 SUS grad students participating both on and off campus in the areas of social, environmental, and economic justice issues. FYSeminar courses offered with an ARTs component exposes students to a unique pedagogical approach to hands-on, experiential learning of which content, skill set development, action research and student engagement are fruitfully intertwined and connected. This spring, each team is posed with the question, “What is Action Research?” and how does this work connect to community engagement, civic learning, and collaboration. Each poster will answer this question and share how Action Research has engaged students in hands-on experiential and civic engagement throughout the semester and year.

Waterways in the lower Colorado River basin were habitats defined by periodic flooding events as a result of snow melts and seasonal rains. With the implementation of dams those waterways have been drastically altered to represent an equilibrium habitat that is the same year round. The roundtail chub (Gila robusta) and bonytail chub (Gila elegans) are species of fish native to the Colorado River Basin. Investigation of the morphology of these species helps us understand the habitats in which they once thrived. We looked at the vertebral column morphology, red muscle location in the peduncle and shape of the fins. Fish were placed in a dermestid beetle colony to have the skeletons cleaned for analysis of the vertebral column. For investigation of red muscle location, seven sections were cut based on a percentage of standard length. Lastly fin aspect ratio was taken from pictures of specimens using imageJ. We compared the roundtail chub and the bonytail chub to the common carp (Cyprinus carpio) and mackerels (members of the family Scombridae). We saw similarities in the vertebral structure of the bonytail and the mackerels which suggested evolutionary convergence in response to swimming modes. The mackerels developed a caudal peduncle vertebral morphology that is specialized for constant swimming. As of 4-19-13 UG Symposium Presentation Abstracts The bonytail has developed similar morphology as a response to times of high flow during flooding. It is important to understand how these fishes once interacted with their environment, to truly know what kind impacts dams, diversions and reservoirs have on these native species.

Littleben, Crystal Faculty mentor: Michael Lerma, College of Social and Behavioral Sciences (SBS) What are the Affects of Historical Intergenerational Trauma Among the Navajos on the Navajo Reservation As of 4-19-13 UG Symposium Presentation Abstracts As of today, there are over 173,987 enrolled members on the Navajo Reservation. Majority of Native Americans were/are still affected by historical trauma today. What are the effects of historical intergenerational trauma among the Navajos on the Navajo Reservation? This dissertation will analyze psychological historical trauma within the Navajos. It will give you a closer look of what the Navajo people went through historically. Historical trauma is defined as a cumulative emotional and psychological wounding, over the lifespan and across generations, emanating from massive group trauma experiences. Horrible events damage people, families and communities. Trauma creates distance, distrust and disconnection between people. Based on definition alone, is this the answer to help heal the Navajo people on the Navajo Reservation? The methods I will be using will be from oral accounts, books, articles, videos, and some personal interviews with Navajos. Litvack, Emily Jackson Leonard, Emily Litvack, Allison Whiteford Faculty mentor: Joseph Shannon, College of Engineering, Forestry and Natural Sciences (CEFNS) Using the Phylum Bacillariophyta to Determine Ecological Conditions of Streams in Northern Arizona's Rim Country As the intensity and frequency of wildfire increases, it has become ever more important to understand its effects on the environment. The goal of this research is to determine long-term effects of wildfire on stream ecology using the phylum Bacillariophyta (diatoms) as a bioindicator. By estimating diatom density in sediment samples taken from streams affected by wildfire 23 years ago and streams affected by wildfire 4 years ago, we can compare and contrast recovery. It was hypothesized that either H0: There is no difference in levels of each parameter between streams or H1: Streams impacted by wildfire will show decreased levels of biological parameters. Silt samples were taken from 6 first-second order streams throughout Northern Arizona’s Rim Country; each was affected by either the 1990 Dude Fire or the 2009 Rim Fire. Samples were taken 3 times across 3 randomly selected sampling stations per stream. Diatoms were cleaned and isolated using a standardized procedure of the USGS National Water Quality Assessment Program and prepared on microscope slides. A self-created approach to diatom counts was used; slides were magnified 400x and 30 views per slide were counted. A total of 31 slides from Fall 2012 were counted for statistical analyses. Average diatom counts per turn are as follows: Bonita: 14.85416667 Dude: 0.866666667 E. Verde: 21.04761905 Ellison: 56.11666667 Pine: 29.6037037 Comprehensive results will contribute to current understanding of long-term effects of wildfire on stream ecology.

Several of Raytheon’s weapons use lanyards to mechanically activate devices upon release. The current lanyard system is highly susceptible to extreme temperature changes and contaminates which lead to failures in activation. As a result, we have been working to find a new design that will: operate between -50⁰C to 150⁰C, have an activation force of 50N, be assembled and installed in under 30 minutes, cost less than $300 in materials and components must fit within current housing constraints. Based on Raytheon’s current design, we’ve noted several areas for improvement. These areas pertain to exposed surface area, cost of materials and machining, complexity of components and installation. Our proposed design reduces the surface area by 41% and eliminates a number of hardware components. This simplified design should improve installation time and reduce failures due to contamination. The design will be experimentally tested according to Raytheon’s constraints and modified appropriately. It is predicted that this testing will identify the most suitable solution to Raytheon’s current problem.

In the past, the creators have been limited to images comprised of blocks and movement and story were limited to the memory that the device or disk could hold. It is only recently that technology has been able to fulfill the creator's full vision. Without the shackles of old technology, developers now are able to create entire worlds and situations that are artistic in nature. But copying artistic ideas and placing them in a virtual world does not necessarily qualify virtual games as an artistic medium. It needs to contribute to the artistic community and bring something new to the table. Virtual games do contribute new ideas and ideas that cannot be fully realized in a novel, painting or motion picture. It is through the interactive nature and the choice to ignore, save or destroy characters that brings new content to the artistic community. Also, the medium is able to create entire worlds that critique the status quo and comment on the human condition, religion and morality. This presentation will analyze how this is possible through visual examples from current, popular video game franchises.

Lovell, Lindsey Kevin Drees, Jeffrey Foster, Katy Parise Faculty mentor: Jeffrey Foster, Kevin Drees, College of Engineering, Forestry and Natural Sciences (CEFNS) Genetic Diversity of North American and European Geomyces destructans Isolates from Bats and Cave Sediment Determined with Multi-Locus Variable Number Tandem Repeat Analysis The recent emergence of Geomyces destructans (Gd), the causative agent of epizootic WhiteNose Syndrome (WNS), has resulted in the death of approximately 5.5 million hibernating bats in 22 U.S. states and 5 Canadian provinces in eastern North America. Gd is a cold loving fungus that not only causes disease in hibernating bats, but is also a prominent member of the sediment microbial community in WNS-affected caves. Gd has been isolated from bats in Europe as well, but the mass mortality associated with WNS has not occurred there. Our current hypothesis is that Gd is an exotic species that was introduced to North America from Europe rather than a native species that developed pathogenicity. We developed a panel of 24 Variable Number Tandem Repeat (VNTR) assays to explore Gd genetic diversity. Results indicate low genetic diversity in North American strains relative to European strains, supporting a recent introduction of an exotic strain to North America followed by rapid spread. Furthermore, we detected variation between North American bat and sediment isolates consistent with a divergence of the organism’s niche from bat pathogen to soil microbe. Lowery, Mary Faculty mentor: Francis Smiley, College of Social and Behavioral Sciences (SBS) Acrchaeological Correlates of Gopalpur Culture The “Archaeological Correlates of Gopalpur Culture” poster illustrates village life in Gopalpur, a small village of less than one thousand people in southern India. My research focuses on three key aspects of Gopalpur culture: religion, agriculture, and social life. The poster highlights material correlates of each cultural aspect, like tools, ceremonial objects, and personal decoration items. The poster examines each material correlate's integrity and patterns of use to make predictions on the availability of archaeological correlates in 2,000 years. My research hinges on the ethnographic account of Gopalpur by Alan Beals in 1964, with updated demographic supplements. Lytikainen, Sarah As of 4-19-13 UG Symposium Presentation Abstracts Mikaela Land Faculty mentor: Nora Dunbar, Christina Moyer, College of Social and Behavioral Sciences (SBS) Relationship Satisfaction & Anxiety There are many psychological disorders that can play a role in intimate relationship satisfaction. Previous research shows that anxiety is one of the leading psychological disorders that directly impact relationship satisfaction. There are many forms of anxiety so there may be many different characteristics for the problems in a relationship. Though there have been many studies on the relationship of relationship satisfaction and anxiety using various age groups, little to no research has been conducted using college aged participants specifically. The purpose of this study is to find out if there is a negative correlation between anxiety and intimate relationship satisfaction within this age group. The participants were heterosexual individuals who had been in a relationship for more than 3 months. Those in dating relationship and those who were married were included in the survey. Most of the participants in the study were between the ages of 18-25 and female. All participants took a survey, containing an anxiety measure and relationship satisfaction measure. It is anticipated that there was a negative correlation between anxiety and relationship satisfaction. These results could add to previous findings and could possibly be used to form strategies for couple's therapy or other such means MacKenna, Perry William Huffman, Ann Huffman, Joseph Barbour Faculty mentor: Ann Huffman, College of Social and Behavioral Sciences (SBS) Students’ Texting Behavior: What Role Does Narcissism Play? The study investigated predictors of in-class texting behavior, hypothesizing that, while boredom contributes to an increase in overall texting, those students who are more likely to text during class display narcissistic tendencies above and beyond feeling bored. Students were surveyed on texting frequency (in and out of class), reasons for texting (Flanagin, 2005), and levels of narcissism (NPI; Raskin & Terry, 1988). Results showed that boredom is a common reason for texting in many situations, yet also found narcissism to be a unique predictor of texting in socially unacceptable situations, such as during class. Students who displayed narcissistic tendencies cited the need to impress people as a significant factor in the decision to text in class. Madi, Melody Faculty mentor: Christine Lemley, College of Education (COE) Ethnicity in the Classroom The overarching question to be answered through this Oral History Project is, "How do teachers effectively integrate students’ ethnicity into the elementary classroom?" I have interviewed a teacher from Puente de Hozho magnet school in Flagstaff where the students are exposed to English, Navajo, and Spanish. This project reviews practical ideas of how to foster an awareness among students where people of different races feel respected, welcomed, and celebrated. In this As of 4-19-13 UG Symposium Presentation Abstracts increasingly diverse nation, such questions must be critically processed in order for the teacher to foster diversity and equality in the classroom. magoffin, caitlin Teresa Butman Faculty mentor: Abbe King, College of Health and Human Services (CHHS) Reducing Catheter Related Bloodstream Infections: Which disinfectant is most effective to clean needle-less access ports on central venous access devices, 70% Isopropyl alcohol or 2% Chlorhexidine in 70% Isopropyl alcohol? Every year 15 million central line catheters are placed in patients across the country. It is estimated that 80,000 bloodstream infections result from these catheters in the ICUS, and 250,000 across all units, annually. (Centers for Disease Control and Prevention [CDC], 2010). The cost of these catheter related bloodstream infections, CR-BSI, is considerable, especially in terms of patient safety and morbidity, and in terms of financial consequence. Central lines, more than any vascular access catheter, are more susceptible to infection. The cost of these nosocomial infections is estimated to have exceed 1.8 billion dollars thus far (The Joint Commission [TJC], 2012). An estimated 50,000 lives each year are claimed by infections related to CR-BSI's. CRBSI's are one of the most deadly nosocomial infections, with a morbidity rate of 12%-25% (TJC,2012). The ramifications of these infections are so severe that the Institute for Health Improvement listed them as one if six major health initiatives (Hadaway, 2006, p. 52). The bacteria responsible for CR-BSI's can be introduced to the body through many modes. One major source of infection comes from the hubs, or injection caps, of the needless systems. Disinfecting these hubs prior to, and after access the central line is a pivotal component of preventing CR-BSI's. But which disinfectant is most effective? The CDC recommends using Chlorhexidine, Iodine or 70% alcohol, but gives no specifics as to which is preferred, while The Joint Comission suggests 2% Chlorhexedine Gluconate/70% Isopropyl alcohol (TJC, 2012). This literature review considers the most recent research to investigate this question. Malone, Shari Shari Malone, Kevin Moorhouse, and Allison Ritter Faculty mentor: Brant Short, College of Social and Behavioral Sciences (SBS) The Pursuit of Happyness: Poverty in the Media In our research project, we will analyze the movie “Pursuit of Happyness” (2006), which was created to act as a vehicle to promote dialogue about poverty. The purpose of our research is to determine the media’s portrayal of poverty, wealth, and the working class. Additionally, we will conduct an in depth analysis about the challenges that prevalent media images and notions pose to those who are homeless or live below the poverty line in the United States. To conclude, we will use prominent theories in communication studies to respond to poverty in a positive way. Maltinsky, Sara Faculty mentor: David Wagner, College of Engineering, Forestry and Natural Sciences (CEFNS) As of 4-19-13 UG Symposium Presentation Abstracts Where is the genomic break that delineates the high copy and low copy regions in pancreatic cancer cells? Pancreatic tumor cells have high expression levels of proteins associated with cellular growth, such as the KSR2, ERRB3, CDK2, STAT2, TBK1, and IRAK3. These proteins are encoded on chromosome 12 in independent arrangements. DNA analysis of all of these regions detected an 8-fold higher copy number in cancer cells compared to non-cancer cells. This striking observation is most parsimoniously explained by a hypothesis wherein all of these regions are linked together at the genomic level due to a genomic rearrangement not observed in non-cancer states. To test this hypothesis we wanted to identify the fusion regions that may link the high copy regions by delineating the break between high copy and low copy regions. We located this break by a primer walking strategy combined with real time PCR. This enabled us to detect copy number differences at 100-200 base pair increments in genomic regions spanning 4,000 base pairs. Because we identified the precise location of the break, we will be able to decode the sequence of the region that directly flanks the high copy region in the cancer cells.

Maoz, Edan Faculty mentor: Melissa Santana, College of Arts and Letters (CAL) Designing a home for the ADHD user While it may not seem like a debilitating affliction, Attention Deficit Hyperactivity Disorder (ADHD) affects millions of people throughout the world in ways that many of us have trouble relating to. Perhaps some of the most common issues ADHD sufferers encounter all occur in the home. Simple things like getting caught on door handle, getting distracted by furniture patterns, or not being able to find something you need in storage are all problems encountered on a daily basis by ADHD sufferers living in a world built for a majority population. However, their constant inconveniences in their homes can be mitigated by some deliberate and specific design considerations. This is where my research comes in. My project includes an analysis and examination of everyday distress that ADHD sufferers deal with, and more importantly, how to eliminate these problems. In my research, I have uncovered several design concepts and how they assist in the lives of ADHD sufferers. To go with the design problems unique to those with ADHD, as a designer, I would have to address other design needs like plumbing trenches, existing and immoveable structural walls, and dealing with a homeowners association. Combining these issues, I must overcome them to As of 4-19-13 UG Symposium Presentation Abstracts make an ADHD friendly house so those afflicted can live their lives in their homes as comfortably and stress free as possible. Marshall, Cassandra Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) A Comparison of the Predictors of Problematic Alcohol Use in Family History Positive and Family History Negative College Students In the last few decades, drinking among American undergraduate college students has been on the rise. The Northern Arizona University’s annual Clery Report documented 1,181 alcohol violations in 2010, compared to 1,004 in 2009. Researchers have pointed out that binge drinking is by far the single most serious public health problem confronting American colleges. The purpose of this study was to identify how specific predictors of problematic alcohol use differ between Northern Arizona University undergraduates with (FH+) and without (FH-) a family positive history of alcohol abuse. Two hierarchical multiple regressions will be conducted (one for each family history group) in order to examine differences in how demographics, drinking expectancies, religious commitment, and academic involvement predict problematic alcohol use. The researcher expects to find differences in the magnitude of the predictive relationships between each variable and problematic drinking based on whether or not the student is from a family with or without a history of problematic drinking. The purpose of this research is to determine which factors interventions should focus on for students with alcohol use problems from each type of family. The researcher hopes that universities will, based on the study’s conclusions, create programs tailored for their undergraduate populations to increase the currently low rates of success of past programs. Marshall, Colton Margaret McKever, Paul Doose, Ryan Lessley Faculty mentor: Wolf-Dieter Otte, College of Engineering, Forestry and Natural Sciences (CEFNS) Classroom Attendance Solution Using Facial Detection and Recognition Attendance in university classrooms can be a difficult to manage, especially in large classrooms with hundreds of students. Unfortunately, because attendance is often not taken in classrooms, students are less likely to attend classes. Research shows that regular attendance is directly correlated to a student's success in a classroom. There are many methods instructors use to take attendance at NAU, but these procedures are time consuming and allow students to misrepresent their attendance. This project aims to provide an automated attendance system that works in a wide range of classroom sizes and is quick and simple for instructors to apply. Our system utilizes facial recognition technology by photographing a classroom using multiple cameras, then compiling a list of known present students. During our development work there were several requirements we had to consider. One of the main goals was to ensure a highly accurate rate of recognition. We designed our system using a pipe and filter architecture, allowing it to be easily upgraded or adapted to different needs. As of 4-19-13 UG Symposium Presentation Abstracts Although our system is presently a long way from being integrated with NAU’s current infrastructure, this proof-of-concept shows that a facial recognition system which is quick, easy to use, and ensures the privacy of those photographed is both feasible and useful. Martinez, Bennet Emily Brown Faculty mentor: Andrew Koppisch, College of Engineering, Forestry and Natural Sciences (CEFNS) Efforts to isolate and quantify the siderophore petrobactin from various environmental bacteria Siderophores are small molecules produced by bacteria to find usable iron in the environment. They work as a chelating agent, with a high iron affinity. Siderophores bind to iron in the organism’s environment in a manner which allows it to be easily re-absorbed by the bacterium. Bacteria require iron in order to grow and thus siderophores can be very influential in their ability to cause disease. However, little is known about the siderophores used by many strains of bacteria. In this project, we have examined production of the Siderophore petrobactin by several strains of Bacillus thurungiensis. These strains were grown in an iron deficient environment to encourage the production of siderophoresm and the compounds were identified with the use of the Chrome azurol S assay. This assay has an iron-containing dye within it and serves as an indicator of molecules with a higher affinity for iron such as a Siderophore. The results of our assays will be discussed.

Greer Faculty mentor: Erika Nowak, College of Engineering, Forestry and Natural Sciences (CEFNS) River Otters – Possible Ecological Impacts on Threatened Riparian Species of Arizona After being extirpated from their former range, river otters (Lontra canadensis) were reintroduced to the Verde River of Arizona in the 1980s. Since that time they have expanded their range to include areas inhabited by the increasingly threatened Mexican gartersnake (Thamnophis eques) and the narrow-headed gartersnake (Thamnophis rufipunctatus). Previous research revealed the river otters in the Verde Valley have a diet consisting primarily of nonnative species. However, the impact those otters have on aquatic snakes has not been documented, prompting the investigation into the diet composition of otters in areas known to be co-inhabited by the threatened gartersnake species. Otter scats were collected in the Verde Valley between 2010- 2012 from otter latrines in verified co-occurrence areas. Fecal samples were washed, removing excess debris with a two-part filtration system. The washed samples were weighed prior to blunt dissection and sorting. Prey items found in each sample were separated by type and weighed after identification to determine percent composition of the individual’s diet. Common prey items identified in the samples thus far include: crayfish, terrestrial and aquatic invertebrates, mammal hairs, fish otoliths and bones, anuran bones, currant (Ribes spp.) berries and seeds, and vegetative material. Continuation of the project will reveal As of 4-19-13 UG Symposium Presentation Abstracts possible positive or negative predatory interactions of river otters with Mexican and narrowheaded gartersnakes, as well as provide data for future research projects.

Maughan, Weston Dr. Stephen Tegler, Dr. Will Grundy Faculty mentor: Stephen Tegler, Will Grundy, College of Engineering, Forestry and Natural Sciences (CEFNS) Indentification of Absorption Characteristics of Oxygen Ice for Comparison to Icy Celestial Bodies We present laboratory FTIR transmission of O2 ice diluted in N2 over the 30K to 60K temperature range. The spectra yielded absorption characteristics of O2-ice bands residing in the infrared wavelength range. We found that the O2 bands are sensitive to the temperature, phase, and concentration of O2. Such sensitivity could help measure the temperature and surface compositions of icy bodies residing in the outer solar system. Next, we will compare our lab spectra with telescope spectra of Kuiper belt objects to look for O2-ice on the surfaces of these bodies. Detecting O2-ice on Kuiper belt objects is of interest as it would provide evidence of solid state chemistry on their surfaces as well as indicating the presence of a resource that could be used for fuel or life support. Mayoral, Joshua Faculty mentor: Fernando Monroy, College of Engineering, Forestry and Natural Sciences (CEFNS) Mucin gene expression during Toxoplasma gondii infection Intestinal epithelial cells are among the first cells in the gastrointestinal tract exposed to numerous microorganisms. These cells are shielded from the external environment by varying layers of mucus fundamentally composed of mucin proteins. Mucin proteins are heavily involved in innate immune mechanisms, deterring microbes both at mucus membranes and at epithelial cell surfaces. Toxoplasma gondii is a highly prevalent parasitic infection worldwide. Infection is usually asymptomatic in a healthy host but very lethal in immune-compromised individuals. The common route of infection brings the parasite into contact with intestinal epithelial cells. As of 4-19-13 UG Symposium Presentation Abstracts However, the role of mucin proteins during this initial infection has not been previously investigated. Evaluation of mucin gene expression during infection was performed by extracting RNA from both human and mouse intestinal epithelial cells. RNA was converted to cDNA and mucin genes expression was analyzed by PCR methodology. Results demonstrated significant increases in several mucin genes in mouse intestinal epithelial cells, but no significant changes in mucin genes were observed in human cells. These results suggest differentiated immune responses by these two species in terms of mucin gene expression, and a further understanding of these immune responses may lead to potential preventative therapies against a highly successful parasite. McCormick, Michael Greg Andolshek, Alex Koch Faculty mentor: Eck Doerry, College of Engineering, Forestry and Natural Sciences (CEFNS) Group Wrangler: A Web-based Group Management System Groups are a fundamental concept in any large organization or social circle. Managing groups is a complex challenge that encompasses managing the group/subgroup hierarchy, analyzing group characteristics, and supporting intra-group and inter-group communication. While there are a number of software systems available for group management, many of these systems are designed for workflow management or casual social groups. Existing systems are unable to handle efficient creation, reorganization, and communication within complex, hierarchical group structures. The lack of a suitable group management system is the primary motivation for the establishment of Group Wrangler, which is being developed to support the Global Science and Engineering Program (GSEP) at Northern Arizona University. As Assistant Director of GSEP, our sponsor, Melissa Armstrong, manages a rapidly growing group of GSEP students that fall into multiple overlapping groups and subgroups, defined by academic status, language, major, and other characteristics. Group Wrangler is an open-source, web-based application that supports an intuitive experience for creating and managing groups and subgroups. It combines the analysis tools of group management software with the communication aspects of social sites. The system provides (a) visual analysis tools (charts, graphs, and tables); (b) secure communications channels (blogs, forums, etc.); and (c) group management methods (automated grouping and manual grouping). Additionally, Group Wrangler emphasizes usability, extensibility, and maintainability. Although we are developing Group Wrangler to meet the specific needs of our client, we envision this system being useful for a wide variety of group management needs.

Propper, College of Engineering, Forestry and Natural Sciences (CEFNS) Gene regulation of Triiodothyronine during Gonadal Differentiation in Xenopus laevis Thyroid hormones regulate many important processes during development and are vital in amphibian metamorphosis. The thyroid hormones thyroxine (T4) and triiodothyronine (T3) As of 4-19-13 UG Symposium Presentation Abstracts circulate in the blood and the active form T3 acts on target tissues to regulate transcription of gene products. The purpose of this study is to determine the effects of T3 in regulation of specific genes involved in the process of gonadal differentiation in Xenopus laevis. This study tests the hypothesis that TH’s affect gonadal differentiation through induction of changes in expression of SF-1 and CYP19, two key genes directing gonadal development. In this study Xenopus laevis was used as a model to study the effects of exogenous T3 on gonadal differentiation during metamorphosis. X. laevis tadpoles were received at NF Stage 53 and acclimated to pond water before dosing. The control group (n=10) was raised in the absence of T3 and the test group (n=10) was dosed with 10nM T3. After 72 hours tissues were collected, RNA was extracted from the gonads and PCR was performed to determine the relative abundance of genes responsible for gonadal development. We found no significant difference in mRNA abundance between the treatments suggesting that short-term exposure to T3 has no affect on gonadal development. Longer term exposures are necessary to determine if thyroid hormone is important to gonadal differentiation.

McTyre, Ellie Hannah Christensen Faculty mentor: Lauren Berutich Campus and Community Based Action Research Teams FYSeminar Program, University College, University College Action Research and Engaged Learning: AGWA Fostering just and sustainable communities in northern Arizona through engaged learning, community partnerships, and action research A component of CRAFTS (Community Reengagement for Arizona Families, Transitions, and Sustainability), the Campus and Community Based Action Research Teams (CBARTs) create dynamic intergenerational hands on learning communities, bringing first year seminar students, returning undergraduates, masters students in the sustainable communities program and community partners into a collaborative relationship. There are over 10 Action Research Teams, a range of 250 to 500 undergraduate students and 20 SUS grad students participating both on and off campus in the areas of social, environmental, and economic justice issues. As of 4-19-13 UG Symposium Presentation Abstracts FYSeminar courses offered with an ARTs component exposes students to a unique pedagogical approach to hands-on, experiential learning of which content, skill set development, action research and student engagement are fruitfully intertwined and connected. This spring, each team is posed with the question, “What is Action Research?” and how does this work connect to community engagement, civic learning, and collaboration. Each poster will answer this question and share how Action Research has engaged students in hands-on experiential and civic engagement throughout the semester and year. Meinel, Eileen Nolan Bade, Dean Buttacavoli, Ian Hanf, and Lindsey Nicks Faculty mentor: Diana Elder, College of Engineering, Forestry and Natural Sciences (CEFNS) Landscape Connectivity: Maintaining Corridors for Wild Animal Movement in Urban Areas Landscape connectivity describes how the structure of the landscape facilitates or impedes the movement of species between patches of habitat. Connectivity is positively associated with population viability, and can be measured by the presence and use of wildlife corridors. Wildlife corridors are linear habitats that connect patches of similar habitat and promote the movement of organisms across a fragmented landscape. Corridors provide vital access to resources including food, water, shelter and mates, and support the life cycles of broad-ranging predators, roaming ungulates, migratory birds, and habitat specialists. Landscape connectivity guards against genetic isolation of populations, and enables movement in response to climate change. Human development, urbanization, and land use change contribute to habitat fragmentation and threaten connectivity. Corridors are also susceptible to degradation and loss of function due to fire, weather events, predation, and disease. In northern Arizona, freeways, railways, pipelines, fences, and even neighborhoods bisect wildlife corridors. Diverse stakeholders and land management agencies also pose a challenge to maintaining connectivity in the region. Strategies for conservation ecology must include identification and preservation of existing corridors and creation of wildlife linkages where there is discontinuity between patches. Meinel, Eileen Faculty mentor: Tina Ayers, College of Engineering, Forestry and Natural Sciences (CEFNS) Microorganisms in Vermicompost Tea The purpose of this study was to investigate the microbiological activity of vermicompost tea and develop a working vermicompost tea production system in the N.A.U. Teaching Greenhouse. An aerated vermicompost tea system was chosen for its low odor potential and faster brew time as compared to a non-aerated, anaerobic tea. Fresh vermicompost was obtained from the greenhouse worm-composting bin and suspended in a 1:5 part volume of dechlorinated water, at varying temperatures from 18-28ºC, and with the addition of various microbe nutrients including unsulphured molasses, kelp meal, and oat flour. Dropper sampling was done at 24, 48, and 72 hours and direct microscopic counts were conducted to determine the number and type of microbes present. Microbes were identified as belonging to one of four categories: bacteria, protozoa, fungi, and nematodes. Qualitative comparisons of samples revealed differences in the dominant type and relative number of microorganisms at each phase and between brews with As of 4-19-13 UG Symposium Presentation Abstracts differing additives. Results from this study suggest that time, temperature, and the availability of nutrients are vital factors in microbial growth. Warmer temperatures and the addition of nutrients increase the growth rate of bacteria and protozoa, while extended brewing times and oat flour encourage the growth of fungal hyphae. Nematodes, which are generally common in vermicomposts, were not well-represented in the liquid extracts. Further study is needed to determine how the quality of the parent material fed to the worms, and the age of the vermicompost used, affects the quantity and types of microbes present in the tea. Merrell, Bryn Sean Canterbury, Hannah Stitizer, Kiersten Wilber Faculty mentor: Scott Anderson, College of Engineering, Forestry and Natural Sciences (CEFNS) A Strategic Plan to Eliminate Plastic Bag Use in Flagstaff The continued use of plastic bags to meet the demands of modern society has proven to be a prevalent ecological issue. Plastic bags make their way into the environment causing pollution and unnecessary waste. The motives for production are the inexpensive costs to manufacture and to provide convenience to consumers. However, this does not outweigh the long-lasting environmental damage they cause. This poster presentation will focus on a strategic plan that aims to eliminate the use of plastic bags in Flagstaff, Arizona. This plan incorporates a wide variety of approaches to reach the ultimate goal. These include: education, outreach, working with local businesses and management, and an increased availability of reusable bags and boxes. Each of these is based on research of similar programs and the success and/or failures these have had. With the elimination of plastic bags, it is anticipated that the local Flagstaff environment will be improved, waste will decrease, and citizens will become more conscious of their choices and thus be more receptive to sustainability. The poster will further discuss the projected success and impact of the plan and where improvements may need to be made once implemented. Merrell, Bryn Faculty mentor: Roderic Parnell, College of Engineering, Forestry and Natural Sciences (CEFNS) Sea Turtle Migration Study in Uruguay The migration of sea turtles along the Uruguayan Coast was analyzed to create a migration prediction model of turtles in the Atlantic Ocean. This is a study created by the non-profit, Karumbé, that studies migration patterns and focuses on conservation and rehabilitation. Of key interest was the species of turtle caught along the coast and the estimated age and health condition. Although the project is still continuing, it is hypothesized that the sea turtles caught along the Uruguayan coast migrate from Surinam, or possibly the southwest tip of Africa. In 2011, over 300 turtles were caught, measured, tagged, and released in the Cerro Verde site on the border of Uruguay and Brazil. The method for capturing the turtles consisted of placing a 50meter net to a stationary buoy off the coast and wait for the turtles to swim into the open net. Caught turtles were quickly collected and brought to shore for tagging. Thus far in the study, it is found that the most common species to include Uruguay in their migration is the Green Turtle. As of 4-19-13 UG Symposium Presentation Abstracts Turtles that have been tagged by a group in Surinam and Brazil have been re-captured in Uruguay, which suggests that their migration is south along the coast from northern South America. With further studies and data, the full migration of these Green Turtles can be mapped out and predicted and could help in conservation efforts in the future. Merz, Brandon Karen Haubensak Faculty mentor: Karen Haubensak, College of Engineering, Forestry and Natural Sciences (CEFNS) Examination of Scotch Broom Effects on Soil Chemistry in Washington State, USA Scotch broom (Cytisus scoparius) is a non-native invasive perennial shrub that proliferates into large thickets following Douglas-fir removal in western Washington. Its establishment in sites following timber removal inhibits reforestation efforts, potentially due to changes in the soil environment. The objective of this study is to determine the effects of scotch broom on the soil chemistry of invaded sites that have been replanted with Douglas-fir, to understand the relationship between Douglas-fir growth and soil characteristics. Soil samples were collected in Washington at the beginning of the Fall 2012 semester from five invaded sites that had been treated with herbicide and manual cutting to remove scotch broom. Sixty Douglas-fir were tagged in each site and randomly assigned to five different control treatments: (no broom removal [control], herbicide spray in the fall, manual cut in the fall, herbicide spray in the spring, manual cut in the spring). The types of soil analysis will include: soil texture, nitrogen availability, carbon to nitrogen ratio, and organic carbon pool size. Results will be compared to Douglas-fir growth and mortality in order to better understand the relationship between Douglasfir success in invaded sites, and effects of the invader on soil chemistry.

As of 4-19-13 UG Symposium Presentation Abstracts Miller, Luke Faculty mentor: Chad Woodruff, College of Social and Behavioral Sciences (SBS) Retro-analysis supporting a distinction between upper and lower mu-suppression band-ranges as indicators of mirror neuron activation Mirror neuron activity has become entwined with many social psychology models of how we interact with, and feel empathy for, others around us. In the past ten years, considerable focus has been placed on the relevance of Mu-suppression, a discernable range of electroencephalography measures that overlap Alpha wave ranges closely and have been demonstrated to be indicative of mirror neuron activation. A study completed previously has benefited from recent developments in our understanding of these band-ranges, specifically a distinction between the upper and lower end. Where previously the entire range from 8-12hz was considered entirely representative of mirror system activity, emerging research indicates that dividing this range and analyzing suppression separately between the 8-10 and 10-12 band-ranges lends further precision when determining mirror activity within a task. This analysis was retroactively undergone to further support this hypothesis. The study itself recorded mu-suppression during a task in which the participant observed a simple video of a hand moving while experiencing attentional distraction. Three blocks are encountered by each participant, one with no distraction, one with an imagery distraction task, and another with a word generation distraction. The last of these showed to be devoid of musuppression compared to the no-distraction block implying that at least some focused attention is necessary to induce mirror neuron activity. Milligan, Anica Faculty mentor: Walter Vannette, Francis Smiley, and Corina Kellner, College of Social and Behavioral Sciences (SBS) Blast From The Past In the Vietnam War, the Northern Vietnamese army scattered the Cambodian countryside with land-mines in the event that allies of South Vietnam would invade and fight the Northern Vietnamese. Today, there are still millions of active and concealed land-mines in Cambodia, which has created a harsh environment for the Cambodians to live in; therefore, the Cambodians have attempted to find and rid themselves of the land-mines. The most common practice for land-mine removal, however, is to pay children to unearth the mines, remove or salvage the parts for re-sale or disposal. This practice, along with the land-mines themselves, causes social, political, and environmental problems for Cambodia. Milton, Jacob Faculty mentor: Matthew Gage, College of Engineering, Forestry and Natural Sciences (CEFNS) Development of Expression and Purification Protocols for Signaling Proteins Involved in Angiogenesis As of 4-19-13 UG Symposium Presentation Abstracts Angiogenesis is the process by which new blood vessels are created from existing blood vessels. After reaching a certain size, growing cancerous tumors send signals to stimulate angiogenesis. This signaling process involves many complex interactions between different proteins. Three specific proteins involved are the cluster of differentiation 47 (CD47), vascular endothelial growth factor receptor 2 (VEGFR2) and thrombospondin-1 (TSP-1). It is known that both VEGFR2 and CD47 are required to begin this intracellular signaling cascade for cells to signal for angiogenesis. TSP-1 inhibits this process by blocking this interaction. While it is known that these three proteins interact, the molecular interactions between the three proteins are largely unknown. The focus of this project is to develop expression and purification systems for immunoglobulin domain 7 of VEGFR2 to characterize its interactions with both CD47 and TSP1. It is currently know that domain 7 of VEGFR2 can be expressed in Roestta Escherichia coli cells, but methods of purification are unknown. The purpose of this project is to discover the purification methods for domain 7 of VEGFR2 so that its interactions with CD47 and TSP-1 can be observed. If the interactions of the proteins can be characterized, then drugs could be developed to inhibit their interactions and prevent cancerous tumors from obtaining nutrition. Mitchell, Taylor Sarah Janwari, Amber Saunders, and Yaiza Van Horn Faculty mentor: Matt Anderson, College of Social and Behavioral Sciences (SBS) Sexual Harassment Victims or Agressors: Who is Less Masculine? There is very little research on how people view the masculinity of men involved in sexual harassment with a woman, but this perspective is important to understand the nature of sexual harassment and its aftermath. The purpose of this experiment was to determine if there is a difference in how people viewed the masculinity of a man when he is the victim of sexual harassment and when he is the perpetrator of sexual harassment. Students from PSY 302W classes took surveys with attached vignettes which described a sexual harassment situation. Half of the vignettes described a man named David harassing a woman named Melissa, and half described Melissa harassing David. Once the data was collected, a two-way ANOVA was done to compare the results of male and female participants who took each survey. Our hypothesis is that there would be no difference between male and female participants, and that they will both view David as being less masculine when he is the victim of sexual harassment. Mix, Ashley Cassie Marshall, Courtney Denevi Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) Alcohol Consumption among College Students: A Look into Age and Drinking Expectancies to Predict Drinking Behaviors Problematic drinking in college students has become more prevalent today than in the previous years. In 2012, the National Institute on Alcohol Abuse and Alcoholism (NIAAA) reported that over 80% of college students drink alcohol and at least half of that portion binge drink. This study was designed to determine the degree to which age and drinking expectancies predict As of 4-19-13 UG Symposium Presentation Abstracts drinking behaviors, and to evaluate whether the relationship between drinking expectancies and drinking behavior depends upon the age of a college student. A sample of 380 NAU undergraduate college students completed the Drinking Expectancy Questionnaire (DEQ) in order to assess assertion, affective change, sexual enhancement, cognitive change, and tension reduction expectancies, and the Alcohol Use Inventory (AUI) in order to measure overall drinking behavior. A hierarchical multiple regression was used to identify whether age and drinking expectancies were important predictors of alcohol consumption, and whether the interaction between these two predictors helps to explain drinking behavior above and beyond the unique contributions age and expectancies make separately. The researchers expect to discover that overall drinking behaviors change in regards to age and specific drinking expectancies. Results may help pinpoint age-specific interventions appropriate for specific types of expectancies.

Montgomery, Ashleigh Ma-Li Metcalf Faculty mentor: Matt Anderson, College of Social and Behavioral Sciences (SBS) Risky Business This study examined the correlation between family structure for the majority of time before a student graduated high school and levels of risk behaviors engaged in during college. Research has shown that students engage in higher levels of risk behavior in college than during other parts of life, and those from non-traditional homes also engage in higher levels of risk behavior. Over 100 students in NAU’s Psychology Research Methods course were surveyed on their family structure before graduating high school and current levels of risk behavior. We predicted that there would be a significant different in the amounts of risk behaviors between participants who lived with both of their biological parents for the majority of the time before graduating high school and participants in all other family structures. Montoya, Marilu Courtney Notah, Trevor Terpening, and Scott Graupensperger Faculty mentor: Joseph Barbour, College of Social and Behavioral Sciences (SBS) Post Decision Dissonance in Desirability As of 4-19-13 UG Symposium Presentation Abstracts The last Ad Hoc Rationalization was performed in 1969, with a purpose of unveiling any reasonable insight into the human brain. It has been almost 50 years since the last Ad Hoc Rationalization so current research is aiming to bridge the gap and find differences in thought processes and desirability, using current college students. The methodology involved self-report from participants and once this data is evaluated, it will disclose more information about how human thought processes are influenced by cognitive dissonance. In order to manipulate levels of desirability that participants were randomly assigned to, prior to administering the test, each participant ranked the desirability level of each given option, researchers altered the availability of one of their choices, and then participants were asked to re-rank the options once more. Researchers expect to see a (1-tailed) negative change in the levels of desirability for the participants’ second choice (i.e. the option that was not manipulated by researchers). The desirability level of the second option is expected to decrease from its initial ranking. Researchers believe there will be a change in the Ad Hoc Rationalization of the students that are tested and the post-decision making process of current students will not differ from the process that was observed in the similar test, almost 50 years ago. Moody, Brian Erin O'Keefe, Mara Pfeffer Faculty mentor: Lauren Berutich Campus and Community Based Action Research Teams FYSeminar Program, University College, University College Action Research and Engaged Learning: Public Achievement Fostering just and sustainable communities in northern Arizona through engaged learning, community partnerships, and action research A component of CRAFTS (Community Reengagement for Arizona Families, Transitions, and Sustainability), the Campus and Community Based Action Research Teams (CBARTs) create dynamic intergenerational hands on learning communities, bringing first year seminar students, returning undergraduates, masters students in the sustainable communities program and community partners into a collaborative relationship. There are over 10 Action Research Teams, a range of 250 to 500 undergraduate students and 20 SUS grad students participating both on and off campus in the areas of social, environmental, and economic justice issues. FYSeminar courses offered with an ARTs component exposes students to a unique pedagogical approach to hands-on, experiential learning of which content, skill set development, action research and student engagement are fruitfully intertwined and connected. This spring, each team is posed with the question, “What is Action Research?” and how does this work connect to community engagement, civic learning, and collaboration. Each poster will answer this question and share how Action Research has engaged students in hands-on experiential and civic engagement throughout the semester and year. Moore, Rush Faculty mentor: Jennifer McLerran, College of Arts and Letters (CAL) As of 4-19-13 UG Symposium Presentation Abstracts Native American Painting During the 20th Century: A Study of an Imposed Cultural Locus The purpose of this presentation is to define the term imposed cultural aesthetic locus and how it relates to Native American painting of the first half of the 20th century. An imposed cultural aesthetic locus is to be seen as a cultural aesthetic locus that is created by an outside group and is in some way imposed upon the group that actually makes use of it. A closer look at how Native American painting was taught, how it was marketed, and what were its main stylistic choices during this period denotes the presence of an imposed cultural aesthetic locus. However, despite the dominance of this imposed cultural aesthetic locus, there still existed some measure of resistance to it among Native American painters working during the first half of the 20th century. Mora, Carolina Christina Davis, Robert Zizo, Jordan Putt Faculty mentor: Mathew Anderson, College of Social and Behavioral Sciences (SBS) Primal Attraction For this experiment, priming effects were employed to determine the general attraction people preferred whether based on personality or physical traits. Research in similar areas has been conducted to find that personality was favored in an experiment while there was no direct effect of priming on physical attractiveness. An experimental survey was used to test both the effectiveness of priming personality and the effectiveness of priming for physical attractiveness. More than 100 psychology 302W students participated in taking these surveys by answering a simple Likert rating scale questionnaire on priming for personality or priming for attraction and kept a control group throughout. The hypotheses for this experiment were: Using priming of perceived societal views we will manipulate the importance rating of physical attractiveness over the importance of personality traits and; using priming of perceived societal views we will manipulate the importance rating of personality traits over physical attractiveness. Based on the hypotheses stated, the results will indicate manipulation of perceived attraction will favor personality or physical.

Moreland, Jessica Melissa Pimentel, Stephanie Sherban, Katelyn Hamel As of 4-19-13 UG Symposium Presentation Abstracts Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) Gender Role Socialization/Partner Preference While plenty of research has delved into the vast field of human sexuality as well as gender roles, this research looks to combine the two subjects. With two broad topics in mind for the independent variable, the researchers intended to identify a link between gender role socialization and partner preference. The researchers were interested in looking at a link between these two subjects rather than replicating research that has already been conducted. The purpose of this research is to attempt to find out information linking adult sexual partner preferences and the learned gender roles during childhood. The researchers utilized available resources to gather participants as well as use existing measures to gather data from the participants. To acquire data, the researchers are utilizing Recalled Childhood Gender Identity/Gender Role Questionnaire, Bem’s Sex Role Inventory, and a basic scale on attraction of an individual’s profile. The researchers hypothesize that the extent to which the individual is exposed to gender socialization during childhood will correlate to the levels of masculinity and femininity they desire in their partner. Morgan, Malie Chad Woodruff and Luke Miller Faculty mentor: Chad Woodruff, Luke Miller, College of Social and Behavioral Sciences (SBS) Brain Electrophysiological Correlates of Facial Affect Recognition Recent research suggests that mirror neuron mechanisms are not only involved in motor behavior but also act as key players in emotional interpersonal cognition. Our research expands on previous research done by Shulte-Rüther et al. (2007) showing significant interplay between emotional interpersonal interaction and brain areas involved in emotion processing, mirror neuron mechanisms, and theory-of-mind (ToM). In this study, we recorded mu and beta rhythms, two putative correlates of mirror neurons. Empathic ability as measured by the Interpersonal Reactivity Index (IRI) compares to Electroencephalographic (EEG) mu rhythms (8-13 Hz) and beta rhythms (15-30 Hz) from electrodes over the sensorimotor cortex. We interpret data within a self-other discrimination model of empathy. Additionally, we hypothesize that mu and beta rhythms, as well as accuracy of emotional judgment will correlate with empathy, as measured by the IRI scores.

Recent tests conducted as a part of Arizona Public Service (APS) routine transformer maintenance have shown the development of hot spots and abnormal levels of gasses within a transformer’s mineral oil at the Cholla Power Plant in Joseph City, Arizona. We As of 4-19-13 UG Symposium Presentation Abstracts examined possible sources of these problems. To accomplish this, we researched several transformer failure case studies, developed a program to rapidly analyze years of dissolved gas in oil data, and carefully examined other crucial data gathered during the life of this transformer. Our assessment of the transformer is a tool for APS to indicate if the transformer is near the end of its operational life. The results of this work will help APS continue to serve its customers with a reliable source of power. Morris, Bobbie Faculty mentor: Michael Lerma, College of Social and Behavioral Sciences (SBS) How have Supreme Court cases affected sovereignty among Native Nations? The purpose of this research is to provide insight into Supreme Court cases and how they have affected tribal sovereignty and its current effects. The goal is to develop ways to assert tribal sovereignty as well keep it from further diminishing. This was done by examining court cases and various tribal governments and how they work with the United States federal government. Through this, I was able to determine how tribal governments have been impacted by Supreme Court cases. This research allow for tribal governments to better defend themselves against Supreme Court cases that aim to diminish tribal sovereignty. Morris, Jackson Faculty mentor: Pam Stephens, College of Arts and Letters (CAL) Slam Poetry Combining elements of performance and poetry, slam poetry is a medium for the expression of a myriad of emotions and artistic styles. Drawing from my personal interests in education and philosophy, I write with the goal of using art to improve peoples' attitudes and interactions with one another. Poetry takes advantage of humans' need to communicate effectively and creatively and (when done well) opens a whole new avenue for self-reflection and interpersonal exchange.

This presentation will briefly outline several aspects of the research including: • Scientific background of previous research completed on this topic • The rationale for such procedure • Details about the intervention (methods) • Data collected (Statistics, graphs, population data, and pre and post intervention analyses) • Explanation of the data collected • Application of this research • Future implications of such research Moynihan, Katie Faculty mentor: Maxine Janis, College of Health and Human Services (CHHS) Mainpat, India: Dental Hygiene Story 2012 In December 2012, Northern Arizona University dental hygiene students and faculty participated in a Multidisciplinary Global Learning Project in Mainpat, India. The dental team of four students, one faculty, and one dentist spent two weeks providing dental cleanings, fillings, extractions, and oral hygiene education to seven Tibetan Refugee Camps. With minimal electricity, clean water, and common resources, the dental team worked efficiently to provide these grateful patients with much-needed treatment. After giving our services to those who need it the most, we discovered that this experience did more for us than we could ever do for them. Mulhern, Shayla Stephen Shuster, Rebecca Beresic-Perrins, Kelsey Banister, Echo Sun Faculty mentor: Stephen Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) Reciprocal transfer demonstrates effect of wastewater effluent on reproductive behaviors in the leech, Helodbella stagnalis We conducted an experiment to determine if endocrine disrupting compounds (EDCs) present in wastewater effluent have an effect on the leech, Helobdella stagnalis. We designed a reciprocal transfer to evaluate the differences in offspring fitness between three local populations of H. stagnalis and their respective water sources: Whitehorse Lake and JD Dam: our reference sites, and Rio de Flag: our wastewater site. Filtered water was used as our control. Wild-caught leeches collected from the sites were randomly distributed among the four different water As of 4-19-13 UG Symposium Presentation Abstracts treatments and we observed time of brood onset, brood size, growth rate, and progeny survival rate between and among water treatment type. We also documented the progression of individual leech's reproduction through pictures taken daily or bi-weekly. Our results demonstrated that the leeches from Rio de Flag, in all water treatments, were the most prolific breeders; most likely due to the presence of EDCs known to induce certain hormones implicated in reproduction and social behavior. Murray, James Zachary Daley, Molly Groyer, Sarah Hamilton, Helena Van Winkle Faculty mentor: Scott Anderson, College of Engineering, Forestry and Natural Sciences (CEFNS) Arizona State Climate Change License Plate Climate change is quickly becoming an issue for the entire global community. With climate change growing and affecting all aspects of society, the creation of a license plate in Arizona to fund environmental organizations can bring awareness to the issue, as well as support actions to mitigate the problem. Arizona has already successfully implemented alternative fuel and environmental awareness license plates and we would like to propose a climate change plate option for Arizona. This would have to be proposed to Arizona Department of Transportation who would evaluate visibility with police. Our design promotes people taking on responsibility to actively participate in their local community to lower CO2 emissions and restore the earth to its original healthy state. If then approved it would have to be passed through legislation. In accordance with Arizona law a fee of $25 would be charged to plate holders, $8 would go to ADOT and $17 goes to the organization. The money would go to the Arizona Climate Change Fund. This would fund research and projects leading to reduce CO2 emissions. The plate will be available to all vehicle owners. An incentive for this plate would be receiving discounted rate for emissions testing. We would not only like to see this implemented in Arizona but across the United States. Murray, James Faculty mentor: Scott Anderson, College of Engineering, Forestry and Natural Sciences (CEFNS) Summer Internship With Arizona Game and Fish In completing an internship with Arizona Game and Fish Department, I wanted to learn different data collection techniques. I was a part of four diverse projects over the summer in order to achieve this. I worked on Camp Navajo Army National Guard Base trapping and banding bats, inventorying snags, outside of Williams, Arizona maintaining trees a part of a restoration effort, and in the Dry Lakes Wind Farm mapping fences. These activities recorded data on animals, vegetation, and manmade items. I learned different measurements to take for each situation and how to take them. Throughout the process difficulties arose and I learned how to adapt to those challenges in the field. The data that other interns and I collected is to be used in making land management suggestions in the interest of the client hiring us to complete the work. As of 4-19-13 UG Symposium Presentation Abstracts Nagel, Brian Faculty mentor: Thomas Paradis, College of Engineering, Forestry and Natural Sciences (CEFNS) Reaching the Sound Barrier: Civilian Population Encroachment on Military Air Bases This presentation brings up the issues associated with the civilian population and military installations. When these bases where originally built, they were placed a decent distance away from civilian communities, for protection against accidents and noise pollution. As time progressed, these communities slowly began to be built closer and closer to the bases, slowing placing the civilians into dangerous areas with the military performing their jobs. This looks into how both the military and cities have adapted and some regulations that the civilian population must follow in order to build under these flight lines, looking specifically at Luke AFB in Arizona, and how they should prepare for an increase of civilian communities.

Natseway, Jacob Laken Cooper Faculty mentor: Mark Schwarzlaender, College of Engineering, Forestry and Natural Sciences (CEFNS) A case of indigenous specialist herbivore (Gnophaela vermiculata) as a potential biological control agent for an invasive weed (Cynoglossum officinale) The purpose of this study is to investigate the effectiveness of an indigenous species in controlling an invasive plant, unlike classical biological control. Two tiger moth species (Gnophaela vermiculata and Gnophaela latipennis) were employed as control agents for houndstongue (Cynoglossum officinale), a noxious weed that quickly proliferates by its barbed nutlets. Lab studies were conducted to evaluate the growth of the moth’s larval stages on houndstongue relative to two natural host plants, Mertensia sp. and Hackelia californica. Caterpillar growth was measured by body weight and by quantifying the amount of frass excreted. Bioassays examined adult females’ visual and olfactory attraction to each plant. Field studies involved a visual assessment of houndstongue defoliation by caterpillars in the wild. Total reduction in plant dry weight was subsequently calculated. The volatile organic compounds used in bioassays were collected from wild houndstongue. Our results indicated that houndstongue is capable of supporting all life stages of both Gnophaela species. In addition, houndstongue in the wild is heavily attacked by G. vermiculata. Although As of 4-19-13 UG Symposium Presentation Abstracts not significant, we noticed a general trend in that both a decrease in seed production (160 seeds produced per non-attacked plant; <50 seeds produced per attacked plants, fig.1) and in seed weight of heavily attacked plants was present (approximately 4.2 grams per non-attacked plants versus 1.0 grams per heavily attacked plants, fig.2). It is unknown if adult moths seek out houndstongue in the absence of natural hosts. The net impact of defoliation on houndstongue population dynamics is also targeted for future studies. Naumann, Amber Faculty mentor: David Wagner, College of Engineering, Forestry and Natural Sciences (CEFNS) Phylogeography of Bacillus anthracis isolates from the country of Georgia Bacillus anthracis, the causative agent of anthrax, is a proven biological weapon. This bacterium forms distinct phylogenetic groups, as revealed by single nucleotide polymorphism markers, and the ecological dispersal of these groups extends globally. We have little genetic understanding of B. anthracis recovered from numerous geographic regions, including the Eurasian country of Georgia. To address this knowledge gap, we phylogenetically placed 283 Georgian B. anthracis strains on the existing global phylogeny to determine that Georgian B. anthracis strains belong to two distinct genetic groups, TEA and Aus94. Aus94 was the dominant genotype. We whole genome sequenced an Aus94 Georgian strain to discover new SNP signatures to increase resolution within the Aus94 group. Screening 273 Georgian strains and a global panel of 179 strains across these signatures resulted in the identification of six new subgroups with Turkish and Georgian samples being closely related. Nelessen, Adam Faculty mentor: Tom Acker, Honors Program Power Prediction Modeling for Wave Energy Devices Ocean waves offer a significant source of energy that could be captured and converted into usable electricity in the United States. Several wave energy converters (WECs), which convert the kinetic and potential energy contained in ocean waves into electricity, are presently under development. As developers continue to test and refine their devices, models that can accurately and efficiently predict loads, motions, and power performance are necessary to improve device reliability and reduce the overall cost of energy. The National Renewable Energy Laboratory (NREL) recently developed a numerical simulation tool, WEC-Sim [Chris McComb, Carnegie Mellon University], that models the motions, loads, and the power performance of WEC devices operating in realistic sea states. This numerical model combines the multi-body code SimMechanics, the frequency-domain boundary element code WAMIT, and the application of wave theory. WEC-Sim is still in the early stages of development and needs to be improved and validated. This presentation will begin with an overview of the basics of wave energy conversion. Then, it will detail the improvements made to the WEC-Sim modeling tool. A discussion of the validity of WEC-Sim results, as demonstrated by comparison to experimental and computational fluid dynamics data, will be given. To conclude, the presentation will discuss the steps that will be necessary to maximize this tool's effectiveness in the future.

This event showcases the engineering abilities of seventy-five international and western United States student teams. It also provides an opportunity for students to gain experience in aerodynamic and structural design, team organization, time management, cost and budgeting, and manufacturing. In the competition, teams gain points by maximizing the payload their plane carries in flight demonstrations, as well as effectively reporting and presenting their designs in technical format. Following a year of conceptual design, engineering analysis, and construction, “The Wright Stuff” has fulfilled all requirements laid out by SAE for the competition. From the outset, the design objective of the team was to introduce the latest precision-manufacturing techniques to remote-controlled airplane design. This was accomplished through the use of NAU’s 3D printing facility which allowed the construction of consistently precise, streamlined wing surfaces. Overall, this design process sufficiently reinforced the coursework of the mechanical engineering curriculum and provided an excellent opportunity for the students to apply their in-class learning to the development of an engineering design. NeSmith, Jalen Faculty mentor: Adam Hoffman, Honors Program Ka 'Aina i ka Pono: the Loss and Pursuit of Hawaiian Sovereigty I discuss the ~two hundred years between the beginning of Hawaiian-American relations and Hawaii’s illegal ratification as a state. I also explain the lasting effects of American commercialism on Hawaiian culture and economy. The paper begins with a review of the discovery of the Hawaiian islands, the friendly trade between Hawaii and Western countries, and the violent end of Capt. James Cook. Despite Capt. Cook’s death, Western interest in Hawaiian commodities kept trade both lively and friendly. Meanwhile, the political unrest in the islands concluded with the uniting of the islands under King Kamehameha I. After a period of peace, Continental interest in Hawaiian trade increased with international competition for the abundant fertile land in the isles. As a result, large spans of Hawaiian land were obtained by wealthy haoles or white people. To preserve land for her own kingdom, Queen Liliuokalani attempted to cease land trade. However, she was foiled when a party of haole, self-named “The Committee of Safety”, brought troops from the U.S. Marines, held the Queen hostage, and established a Provisional Government. The U.S. Senate soon annexed Hawaii as a territory and, despite the promise made by President Cleveland to restore Hawaiian land, ratified as a state. Despite this ratification, the United Nations still recognizes Hawaii as an occupied territory, rather than a part As of 4-19-13 UG Symposium Presentation Abstracts of the U.S. Hawaiian culture remains strong, but blighted by American influence.

Claims have been made that foam rolling helps with muscle tension, reduces pain, and increases flexibility. To date, however, there is hardly any scientific research on the effectiveness of the foam roller on any of these outcomes. This poster describes the preliminary findings of a study that looked at whether foam rolling would lead to greater reductions in muscle tightness and greater improvements in range of motion compared to stretching or no stretching at all. Participants (n=60) were randomly assigned to one of three groups (all n=20): 1) foam roll, 2) static stretching and 3) a control group. Main outcomes were muscle tightness and flexibility of the quadriceps, hamstrings and IT-band. Researchers taking the measurements were blinded to the group assignment to reduce potential bias. Muscle tightness was measured using an algometer, pressing into the muscle at a depths ranging from 0.5cm to 1.5cm and measuring the required pressure to get to that depth. Flexibility of hamstring and quadriceps were measured by active movement as far as possible by the participants. Participants were measured at baseline and immediately after 2 minutes of either foam rolling, stretching or no activity. Participants were measured again after 3 weeks of 4 times per week of foam rolling, static stretching or no stretching, depending on group assignments. Preliminary findings evaluating differences in muscle tightness and flexibility between groups will be described. Recommendations for future research are discussed.

Nicks, Lindsey Faculty mentor: David Williamson, Wendy White, College of Engineering, Forestry and Natural Sciences (CEFNS) Kind Vines Sustainability Report As of 4-19-13 UG Symposium Presentation Abstracts Studies show that the wine industry utilizes unnecessary energy during manufacturing and transportation processes. The sustainable business model Dave Williamson created for his product, Kind Vines, presents solutions to reducing the waste associated with traditional processes. The model used reduces waste by using reusable bottles with permanent labels which are filled and distributed locally. Kind Vines, located in Flagstaff, Arizona offered an opportunity to learn about sustainable methods through hands on experience. The experience included participation in all aspects of the Kind Vines operation, including washing and filling bottles, delivering and picking up of bottles, and product awareness through tasting events at Bashas. Study objectives included development of a deeper understanding of what it takes to be a successful, sustainable business. Other alternative packaging solutions for standard glass were researched; however, the options were very limited, and better suited for areas immediately surrounding wineries. This study concluded that the practices implemented by Kind Vines are ones that could easily be incorporated into towns and cities within a reasonable driving distance from various wine countries around the world. Further studies on how to get this concept accepted on a global level are recommended. Nimer, Adrianna Faculty mentor: Nashelly Meneses,Russell Benford, Steven Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) The Demographics, Distribution, and Public Perception of Free-Roaming Dogs on Saipan During World War II, working dogs were brought to Saipan to aid in the Battle of the Marianas. After this battle, the dogs were abandoned. Today, there is an overpopulation of mix-breed dogs on the island that pose a threat toward humans, domestic animals, and wildlife. In response to this, the government of Saipan is attempting to manage the free-roaming dog population. However, information is lacking regarding the demographics, distribution, and the public perception of this population. I documented the age, gender, sociality, and behavior of the freeroaming dogs. To test how human land use (rural, coastal, urban) and urbanization level (0100%) affect their abundance, I surveyed dogs within rural, coastal, and urban areas. Using public surveys, I investigated how the public views this population. I found that: 1) The majority of dogs were adults, males, in a group, and generally aggressive toward humans. 2) Dogs were more abundant in urban areas (N=21, F= 9.5, p=0.0001) and in areas with highest urbanization levels (N=20, F=14.85, p=0.0001). 3) The public views these dogs as a safety hazard. To better manage the free-roaming dog population, spay-and-neuter campaigns, leash laws, and dog collection operations should be focused in highly urbanized areas.

Many of these places have limited access to electricity. This creates a problem for the As of 4-19-13 UG Symposium Presentation Abstracts Department of Dental Hygiene since many of their tools require electric power. Therefore, they need a power source which can provide continual electric power for their devices. Meanwhile, this power source has to be portable in both size and weight. The task of our team was to design a power source that would allow the Department of Dental Hygiene to operate their Wig-L-Bug mixer/amalgamator tool off the grid for a full day. This design consisted of a lithium polymer battery, an inverter, and a charger. At the end of the last semester in 2012, a portable power source was designed and built. With this power source, the Department of Dental Hygiene successfully provided the humanitarian aid to children in Mainpat in December, and reported that they were satisfied with the performance of this power source. In this semester, our team began with another design idea, mechanical Wig-L-Bug which requires only manual power to operate. The main advantage of the mechanical Wig-L-Bug is that no charging process is required and it is much more portable. This design is estimated to be completed and tested in April. Nolan, Eric Faculty mentor: Karin Wadsack, College of Engineering, Forestry and Natural Sciences (CEFNS) Putting Flagstaff Sustainability Plans in Context This presentation will take a look at what the word "sustainability" means to the city of Flagstaff. Human populations in Flagstaff have tripled since the 1960's under a fossil-fuel based economy. This influx of human settlement has created unique challenges that require unique solutions. Local food production, local activism, recycling, energy production, and a finely-tuned drive toward economic development have all directed the city on its current course as a sustainable community moving away from the use of fossil-fuels. Energy-resource transitioning, regional food availability, social inclusivity, and education are some of the more formidable focuses on how this sustainability can be achieved. Research shows several organizations who have dedicated their resources toward building a sustainable framework centered around community resiliency. The focus of these organizations has been to find a balance between establishing a strong economy while upholding the integrity of the natural environment. Because of the efforts of the studied organizations, and many others, the City of Flagstaff has incorporated its Regional Sustainability Goals. My presentation will demonstrate a "big picture" perspective of what can be done when collaboration and innovation work together in building a sustainable future in Flagstaff.

Although most previous studies associate varve thickness with summer temperatures, precipitation is also an important variable. Lake Linnévatnet (4.7 by 1.3 m, 35 m depth) is on the main island of the Arctic archipelago, Svalbard. The lake receives melt water from the Linné Glacier, located 6 km south of the lake, via the Linné River. Additional discharge is derived from snow melt and precipitation. Previous studies focused on temperature increases during the early summer freshet as the dominant hydrological process causing sedimentation in Lake Linnévatnet. In contrast, this study highlights the importance of lateseason rainfall for generating sediment input to the lake. Sediment traps, an intervalometer (a device was used to record timing of sediment pulses), and weather stations were deployed from September 2011 to July 2012. Biogenic silica (BSi) analyzed from the sediment traps was inversely correlated with mean grain size, suggesting the primary control on BSi is dilution. One fall sediment pulse and two summer pulses were recorded in the traps. The fall pulse contains a high proportion of fine particle sizes, is associated with a significant rise in lake level, and was rainfall-generated. The summer pulses produced coarse sediment sizes, had little effect on lake level, and were products of snow ablation. The differences in the pulses are related to the differences in hydrology of snowmelt and rainfall. These results show that late-season rainfall can produce a significant proportion of annually deposited sediment.

In doing so a 3 month internship took place, in which I worked alongside Environmental Health Specialist inputting bacteriological data into Los Angeles county system database. In addition, I went out to inspect water wells that service multiple As of 4-19-13 UG Symposium Presentation Abstracts municipalities as well as commercial places in Los Angeles County. The internship resulted in a gain of experience on programs that environmental health specialist deal with like the drinking water program. The programs also conveyed the efforts needed scientifically as well as the bureaucracy behind being able to put out suitable quality of water for residence in Los Angeles County. Also, an understanding of the process on how businesses are serviced their water and what steps on attaining a water permit are done in the process. Moreover, the internship was an experience that showed that a future as an Environmental Health Specialist is a great stepping stone towards a career with the federal government or any other private firms that deal with environmental health. Further internships are advisable since experience is major feat to have on ones resume or CV when applying for jobs. Methods • Collect and review water permits issued by the County of Los Angeles • Input Bacteriological sheets sent in from companies tested water systems • Go out to sites in which County supplied water systems are in use and inspect their usage. • In addition, is gaining experience by working with Chief Environmental Specialist and Environmental Health Specialist on other Public Health Projects the County has like Air Quality Results Los Angeles County Public Health Department has distinct programs regarding the health of the environment. With the drinking water program as part of my internship the main focus was to gain a perspective on how to make sure Public Water Systems are functioning properly and in compliance with state issued standards. As part of checking whether public water systems were compliant visits to Cerrititos College in Cerritos, CA were made to check whether decommissioned water well there had properly been put out of use. Upon arrival we were escorted to where the well was used and observed that the well had been cemented and blocked off from public access as issued by state standards. Furthermore, is before going to check out these public water systems review of their water permits were done to check whether or not they are up to date. From checking these permits it was discovered that many of LA counties older Public Water Systems have had their permits outdated for a very long time. Those that have been outdated have been contacted and also followed up upon with Environmental Health Specialist going out to review their public water system and having them to renew or reapply for a permit. Discussion After doing the internship I realized that work as an Environmental Health Specialist is very busy and that there is plenty to learn. Experience is golden. After learning about how water Public health safety is done, one can later then branch out on his or her own and try private companies since you have familiarized yourself with federal and state regulations. Olivas, Araceli Meghan Warren, Steve Palmer Faculty mentor: Meghan Warren, College of Health and Human Services (CHHS) PE Effects on Physical Activity Introduction: The Behavioral Regulation in Exercise Questionnaire (BREQ-2) measures selfdetermined motivation for physical activity. The purpose of this study was to assess the As of 4-19-13 UG Symposium Presentation Abstracts relationship between self-determined regulation and leisure-time PA and describe differences between 7th grade boys and girls. Methods: 143 boys and 137 girls completed surveys at baseline as part of a physical education intervention study. The PA score was calculated from a validated self-report of weekly activity. The BREQ-2, a 19-question survey, consists of five subscales measuring PA motivation: 1. Amotivation (no intention to engage), 2. External regulation (unwilling motivation through external pressures, and unlikely to continue), 3. Introjected regulation (self-pressure to act), 4. Identified regulation (motivation through acknowledgement of PA benefits), and 5. Intrinsic regulation (motivation from the enjoyment of PA). The mean and standard deviation of each BREQ-2 subscale for the total sample, as well as by sex were calculated. Two-sided independent t-tests assessed the differences between boys and girls. The relationship between each BREQ subscale and PA score was calculated with Pearson correlation. Results: 51% of the students were boys, and the majority self-reported race/ethnicity as Caucasian, Native American, or Latino (39%, 26%, and 26%, respectively). There were no statistical differences between boys and girls for any BREQ-2 subscales. PA score and intrinsic regulation was weakly, but significantly correlated (r=0.23, p=0.0002). Conclusion: There were no differences between 7th grade boys and girls in PA motivation. Students with greater physical activity had scores of enjoyment motivating PA. Olivas, Sonora Faculty mentor: Talima Pearson, College of Engineering, Forestry and Natural Sciences (CEFNS) Prevalence of Coxiella burnetii ST20 and ST8 in Global, Commercial, and Rural Environments Coxiella burnetii is the causative agent of Q fever and is found in many mammalian hosts, primarily in livestock. In a previous study we found that at the herd level, milk from approximately 1 in 5 cows tested positive for C. burnetii DNA. Additionally, 99% of nearly 500 commercial milk samples were also positive. The majority of these samples were divided amongst two sequence types (ST20 and ST8) and dependent on animal source (cow versus goat). To determine whether the prevalence of these two genotypes is similar among rural U.S. farms or at the global, commercial level we collected milk from both areas and tested them for C. burnetii DNA. Our results show that while prevalence of C. burnetii DNA is lower in these environments, ST20 and ST8 are still present, indicating that these genotypes are not solely characteristic of commercial U.S. milk. Olsen, Xena Faculty mentor: Jayme Lyn Davis, University College The Representation of African Americans in Film Noir: Whitewashing the Screen Race relations in postwar American society were volatile. The nation experienced the influence of an emerging African American culture through The Great Migration, which increased racial anxieties that were compounded by the growing civil rights movement. The ideologies regarding the stereotypical representations of African Americans were being challenged and this served as As of 4-19-13 UG Symposium Presentation Abstracts a threat to the dominant white culture. The growing pressure from the Communist party regarding race relations flushed out the United States government’s ineffectual and ambivalent stance concerning the resolution of racial tensions and social injustice. All of these historical factors contributed to the outright racist depiction of African Americans in postwar American film noirs. Therefore, the representation of African Americans in postwar American film noirs, such as Kiss Me Deadly, The Killers, Out of the Past, Sudden Fear, The Big Clock, Detour, The Asphalt Jungle, and Double Indemnity reflect the stereotypical socio-political depiction of race in American culture. Olson, Samuel Colin Gray, Alex Mazzeo, and Nicole Williams Faculty mentor: Maggie Hamill, College of Engineering, Forestry and Natural Sciences (CEFNS) Online Scholarship Application The College of Engineering, Forestry, and Natural Sciences (CEFNS) processes hundreds of scholarship applications each semester. CEFNS has received poor results from other application processing tools, and has reverted to the archaic method of paper applications. Team Six Sigma has proposed their Online Scholarship Application (OSA) as the solution to CEFNS’ application processing needs. The OSA is a web application built on the Ruby on Rails framework and uses a MySQL database to store application and scholarship data. It will automatically manage scholarships and all associated data, applications and letters of recommendation, as well as provide a variety of convenience features. Students will be able to log into the system to view and apply for available scholarships as well as upload letters of recommendation. When applications have been submitted, authorized CEFNS employees will use the OSA to view the list of applicants. The OSA provides suggestions based on applicant qualifications, and allows CEFNS employees to collaborate in the selection process. When the selection process has concluded, authorized CEFNS employees will use the OSA to award scholarships to those deemed qualified. The OSA also includes a suite of administrative features that allows authorized CEFNS employees to manage the system. It will allow CEFNS’ employees to add new scholarships to the system, each of which is customized in accordance with the donor’s requirements. The OSA has been designed with CEFNS’ needs in mind and will revolutionize the way scholarship applications are handled at Northern Arizona University. Onofry, Mackenzie Michelle Roesch, Kristen Johnson, and Emily Wiseman Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) Arousal and Memory The uncertainty created by contradicting findings in previous arousal and memory studies led a group of researchers to study the effects of various levels of arousal on recall memory. The study at hand aimed to reduce these discrepancies by employing the utilization of music. Participants were randomly assigned to one of three conditions. All groups were presented with a list of 20 words for a short time segment while either being exposed to no music, low arousal music, or As of 4-19-13 UG Symposium Presentation Abstracts high arousal music. Arousal levels were manipulated as a function of beats per minute. A oneway ANOVA statistical test indicated that there was a significant difference between the three conditions. Further examination of a Tukey post-hoc test revealed that participants in the low arousal music condition recalled significantly more words than in the other two conditions. Participants in the low arousal music condition, on average, recalled four more words than the no music and high arousal music conditions. The results of this study can have far-reaching effects in educational settings. Further research should be conducted on this complicated relationship to enhance the reliability and validity of this study.

Orduno, Jose Faculty mentor: I do not have one, College of Arts and Letters (CAL) Techniques of Ceramic Production in Song Dynasty China This is an overview of the advancements that took place in art during the Song Dynasty in the area of ceramics. How artists in that time were able to create new pieces of work not seen before using revolutionary techniques that are still being used today. The new uses of kilns, carving, and the use of saggers when firing work were all essential tools that these artists used. As of 4-19-13 UG Symposium Presentation Abstracts Ortiz, Alexandra Brianna Layser and Luis Diaz Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) Health Habits and Their Relation to Short-term Memory Performance This study investigates the relationship between daily health habits and short-term memory performance. The participants in the study included 100 undergraduate students enrolled at a university in the Southwestern United States. 40% of the students were male and 60% of the students were female. In order to test the hypothesis, the group of researchers administered a short-term memory test where students looked over a 20-word list for 60 seconds and then were asked to record all of the words they were able to recall from the list. This study found that higher scores of reported health habits (sleep, nutrition, and exercise) had a positive correlation with short-term memory performance. Oyama, Kimberly Chihiro Sasaki, Daren Rodhouse, Blayne Kennedy Faculty mentor: John Georgas, College of Engineering, Forestry and Natural Sciences (CEFNS) Localization Functionality for MCM, a Mobile Commerce Application MoneyClip Mobile (MCM) is a web-based payments infrastructure providing fee-free transactions to customers and merchants through the use of mobile devices. Dr. Joshua Cross of Hermes Commerce, Inc. is planning to make this mobile payment system more robust by providing targeted advertisements, coupons, and management of customer’s loyalty programs. This project involves implementing a localization function that notifies MCM merchants when MCM customers are in their vicinity, allowing the merchant to push a payment request to the customer’s MCM account if the customer makes a purchase. This functionality allows true moneyless transactions. Another piece of functionality we are adding is directed advertisements and coupons based on the customer’s location and transaction history. The customers will have the ability to select the amounts and sources of advertisements that are pushed to their account via the iPhone application, Android application, or website. Customers will be able to customize their settings to choose differing levels of participation from the advertisements. Merchant settings will also be available for change on the website or either mobile application. After the implementation of the merchant and customer interface, which includes Android, iOS, and website platforms, integration testing and user testing will be performed, and documentation for each will be provided. Paddock, Ethan Jacob Milton, Rachelle Eddie and Matthew J. Gage, Ph.D Faculty mentor: Matthew Gage, College of Engineering, Forestry and Natural Sciences (CEFNS) Purification of Receptor Proteins in the Nitric Oxide Signaling Pathway The process of angiogenesis (the growth of new blood vessels) is a common step during development, wound healing, and tissue damage. Angiogenesis is also one of the 6 hallmarks As of 4-19-13 UG Symposium Presentation Abstracts associated with tumor growth. Regulation of angiogenesis involves several different proteinprotein interactions. This study focuses on three interacting proteins: Cluster of Differentiation 47 (CD47), Thrombospondin-1 (TSP-1), and Vascular Endothelial Growth Factor Receptor 2 (VEGFR-2), which are all involved in Nitric Oxide (NO) signaling. The IG domain of CD47 has been shown to interact with TSP-1, inhibiting NO signaling, preventing angiogenesis. It was recently shown that VEGFR-2 associates with CD47 to upregulate NO signaling and this interaction can also be disrupted by TSP-1 but the molecular nature of these interactions are not fully understood. The goal of this project is to characterize the molecular interactions between CD47, TSP-1, and VEGFR-2. The work presented here is focused on the purification of the G1 domain of the TSP-1 protein TSP-1 expression is induced at an OD600 of 0.6 and expressed overnight in BL21 (DE3) E. coli at 25°C and 90 rpm. Cells were collected and lysed with the addition of 1mM EDTA to prevent protease activity and purified using a Ni+2 chelating gradient column to ~90% purity. GST affinity and ion exchange chromatography is being explored to complete the purification. Padilla, Cassie Cassie Marshall, Kristina Guglielmi Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) “Everyone Else Is Doing It”: An Examination of the Motives Behind Binge Drinking Behavior Among Greek-Letter and Non-Greek-Letter Students In today’s college setting, binge drinking and Greek-letter organizations seem to go hand-inhand. Substantial research has been conducted on the prevalence of drinking among Greek-letter students. The motives behind drinking behaviors have also been examined by researchers, and an array of different and varying motives have been implicated. The purpose of this study was to examine the relationship between drinking motives and involvement in Greek-letter organizations. A total of 380 undergraduate students at Northern Arizona University, 16% of whom were involved in Greek-letter organizations, were surveyed on their drinking behavior and drinking motives. Two groups – Greek students and non-Greek students – will be analyzed for significant differences in specific drinking motives, such as social improvement, mental improvement, mood management, and function enhancement. Independent t-tests will be used to conduct the analysis. The purpose of this research is to provide a better understanding regarding the reasons why college students engage in binge drinking, and specifically why Greek-letter students engage in such behavior. More information on this topic may provide valuable information for intervention and education programs that can specifically target both Greek-letter students and non-Greek students. Padilla, Kelsey Chace Gear, Garland Clark, Laura Warden, & Robert Till Faculty mentor: Robert Till, College of Social and Behavioral Sciences (SBS) Effects of Mindful Breathing on Mind-Wandering and Reading Comprehension Mind-wandering occurs when one’s attention is drawn away from the primary task at hand. The current study sought to manipulate the conditions immediately preceding a sustained attention to As of 4-19-13 UG Symposium Presentation Abstracts response task (SART) in an effort to increase or decrease the level of mind-wandering. One condition involved a benign essay, the second gave participants a disturbing essay, and the third condition asked participants to do relaxed, mindful breathing for 8 minutes. Following the essays or mindful breathing, all participants went on to perform a SART task in which they read stories presented one phrase at a time on the computer. For each line, participants pressed the spacebar to advance to the next phrase. Participants were instructed to withhold their spacebar response in the rare situation that the phrase on the screen contained the word “student.” In those cases, the computer would advance the text. Any spacebar response here was counted as an error. Readers were asked to self-report whether they had done any mindwandering. Results showed that those in the disturbing chemical-essay condition reported significantly more mind-wandering than those in the benign instruction-essay condition. Those in the mindfulbreathing condition reported significantly less mind-wandering than those in the instructionessay condition. Those in the chemical-essay condition had significantly lower accuracy in withholding response to “student” than either of the other two groups. In sum, it appears that the disturbing essay induced more errors on the sustained attention task than did the other groups. Pak, Alexa Faculty mentor: Jennifer Musial Women and Gender Studies, College of Social and Behavioral Sciences (SBS) The Control of Birth Control Birth control is something that continues to controls women's bodies well into the 21st century. For my presentation, I want to focus on the various ways these contraceptives control women ranging from biologically, socially, and even through the new implementations of Obamacare. I will also be researching and presenting the direction birth control is headed towards in the future. Pak, Alexa Faculty mentor: Jennifer Musial, College of Social and Behavioral Sciences (SBS) The feminist discourse of Self-defense Self-defense is an area of self-protection that helps women question the male-dominated, patriarchal culture in which we live. It demands that feminism gets physical. This is important because feminism is a cultural, educational, mental, and political movement and self-defense, for women, encompasses the physical capabilities that need to be included in the feminist movement. It empowers women on more that just a level of physicality.

Palmer, Ryan Miles Roux and Dolores Gallardo Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Christmas Ornament Display Structure My Star of Bethlehem LLC is a small online business that sells Christmas ornaments manufactured in Germany. In order to help promote and highlight these Christmas ornaments, the client requested that a portable ornament display stand be designed and manufactured. This structure should have the ability to support up to three ornaments at a time, while elevating them at least six feet above the ground. The design must be collapsible, lightweight, and be assembled or disassembled in less than 30 minutes. Based upon the client’s requirements, our team designed the structure largely out of recyclable materials such as aluminum. It can elevate the largest ornament 8 feet off the ground when measured from the lowest point while elevating the other two ornaments 7 feet off the ground. The structure is divided into 6 sections for ease of manufacturing and future assembly. The heaviest section weighs no more than 25 pounds so that the average adult can carry each piece with minimal effort. The structure is portable when disassembled allowing each section to be transported in a compact sedan. All conceivable safety aspects have been taken into account in the design process. The final structure can withstand gale force winds without bending or toppling. The prototype was also designed with aesthetics in mind making use of polished surfaces.

Parkhurst, David Faculty mentor: Melissa Birkett, College of Social and Behavioral Sciences (SBS) Differences in Affective Decision-Making Between Types of Drinkers as Assessed by Different Formats of the Iowa Gambling Task This research seeks to better understand how types of drinkers differ in their decision-making capacities. Specifically, this study looks at how binge drinkers differ from other levels of nonbinge drinkers in terms of their affective decision-making abilities, which involves an integration of affective and somatic states into decision-making to bias decisions towards more positive long-term outcomes and away from negative ones. Past research has shown that those who engage in binge drinking patterns may have a deficiency in this area, leading to a myopia of future consequences that may account for some of this pattern of drinking behavior. The Iowa Gambling Task is a well-established neuropsychological measure used to assess affective decision-making, and since its creation it has been converted into several alternate versions and computerized iterations. One such example is part of the PEBL battery, an open source battery of classic cognitive and neuropsychological tests. The second goal for this project was to compare the “official” computerized IGT with this open source version in order to contribute to the validity assessment of the free-to-access PEBL task. Subjects were given a survey that differentiated them into discrete categories of various levels of non-binge drinking behavior and binge drinking behavior. They were then administered either the “official” IGT or the PEBL version and completed the task while somatic responses of heart rate and skin conductance were collected. Parkhurst, Diamond Danielle Perry, Emily Wilson, Claire Lower Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) Traumatic Events as Predictors of Substance Abuse in Adolescents Substance abuse among youth is detrimental to the welfare of society as a whole. The purpose of the study was to assess the factors related to the decision to abuse drugs, and to ascertain information that can be applied to treatment and prevention. Specifically, this correlational study examined the relationship between exposure to a traumatic event and substance abuse. The participants were Psychology students at Northern Arizona University, mostly EuropeanAmerican females, aged 18-25. Data was gathered using a survey assessing the frequency of exposure to trauma, and the severity of the traumatic event. In addition, the survey included a measure of substance abuse, and questions about the age of onset. It is expected that findings will indicate that as frequency of exposure to trauma increases, the frequency of substance abuse increases. Similarly, as the severity of the traumatic event will increase, the frequency of As of 4-19-13 UG Symposium Presentation Abstracts substance abuse will increase. Age of onset of substance abuse and the frequency of traumatic events are expected to be positively related and age of onset is predicted to be positively related to the severity of the event. It is expected that individuals who were more frequently exposed to traumatic events and events of greater severity were more likely to begin drug abuse earlier in life and were more likely to abuse drugs frequently. Parrott, Joe Brittany Smith; Christian Valadez; Kara Roof; Mary Rhoades Faculty mentor: Neil Cobb, College of Engineering, Forestry and Natural Sciences (CEFNS) Ground-dwelling arthropod community structure across nine vegetation types in the Canyonlands region One of the most important parts of terrestrial biodiversity is arthropods, which make up the major part. Arthropods are able to show a reflection of the type of habitat they occupy, although little is known about the distribution of arthropod species. The purpose of this study was to determine the occurrence of ground-dwelling arthropod species by sampling nine different habitats in the Canyonlands region of Southeast Utah. It was concluded that the community structure between all nine habitats was unique, and that arthropods respond differently to microhabitats. Patch, Dreux DL Patch, AL Krohn, G Allan, CA Gehring Faculty mentor: Andrew Krohn, College of Engineering, Forestry and Natural Sciences (CEFNS) Soil microbial community response to the introduction of pinyon pine (Pinus edulis) seedlings Pinyon pines (Pinus edulis) are a foundation tree species of the southwestern United States, and are more drought-sensitive than other regional tree species. Pinyons are facilitated under stressful conditions via symbiosis with mycorrhizal fungi. Many lines of evidence indicate that soil bacteria are likely to participate in this symbiotic relationship, but little is known about their ecological roles or their taxonomic identities. In 2009 a P. edulis common garden was installed near Sunset Crater National Monument, AZ. As a subset of trees was transplanted from a greenhouse environment, soil was collected from the planting sites, as well as from the potting soil used to cultivate the seedlings. A year later, soil was recollected from the base of the seedlings to examine how the soil community changed with the introduction of a pinyon pine. DNA was extracted from the soils, quantified via fluorometry and subjected to community amplicon sequencing using variable regions in the ribosomal RNA operon for phylogenetic characterization and taxonomic classification. On average, the introduction of a pinyon seeding approximately doubled the amount of DNA in the soil. Alpha diversity showed in excess of 200 operational taxonomic units (OTUs) present in our study system. A change in beta diversity from pre-tree soil to post-tree soil indicates that the soil microbial community has shifted in response to the introduction of a pinyon pine seedling. Efforts to further characterize the fungal and bacterial communities and determine their relative contributions to the total soil DNA complement are ongoing.

The lack of food education of the American populace combined with the fast food industry's overwhelming need to produce cheap food, with little nutritional value, to rake in large amounts of money is to blame. Once this epidemic is recognized by the U.S. government and its people then ways to solve this health issue can be discussed and implemented. Through means of education and more government regulations, the fast food industry would have less control over the American people and reduce obesity rates in America. Perez, Martha Kiara Weathersby, Brette Martin Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) Overall health and wellbeing The purpose of this study was to examine the relationship between overall health and well-being. The research participants were approximately one hundred students from Northern Arizona University, recruited from psychology students enrolled in 302W during the spring 2013 semester. This correlational study employed the use of two self-report questionnaires and data was collected in the measures which consisted of seven questions apiece. The International Physical Activity Questionnaire and a modified version of Perceived Health and Subjective Well-being questionnaire (Judge, Ilies, & Dimotakis, 2010) were administered during regular class time and took approximately ten minutes for each participant to complete. The International Physical Activity Questionnaire requested information on different forms of recent physical activity in varying amounts from vigorous, to moderate and no activity. While the modified perceived health and subjective well-being questionnaires inquired about the individual’s selfperception by rating their health and current internal views on life. Once review of findings, is complete it is believed that physical activity will influence self realization and promote desirable morale, therefore promoting healthier behaviors which will positively correlate with well-being.

Pichnarcik, Jenna Faculty mentor: Zsuzsanna Gulacsi, College of Arts and Letters (CAL) As of 4-19-13 UG Symposium Presentation Abstracts Psychological Reflections: An Ordered Reality in Painting. Although reality is greatly self-perceived, it is also a shared experience. Despite psychological distinctions and developmental differences, human beings create pictorial images which exemplify the ubiquity of reality through time and space. Paintings from around the world depict images where cultural and temporal influences differ, while spatial relationships tend to be extremely similar, or shared. Space is a psychological reflection of reality, yet not all artists are created psychologically equal. With some exceptions, artists that have disorders and diseases (schizophrenia, cerebral-palsy, developmental disability) have been categorized within a genre of their own. Though, their ability to depict images that resonate no differently than the paintings of psychologically 'normal' artists. The appearance of a grid, and the representation of space and time (reality) in painting has a long and diverse history and one that tells a story about humanity. Piepiora, Kaitlynne Faculty mentor: Anne Scott, Honors Program A Magical World of Inspiration Walt Disney was a visionary of his time that has inspired many others to follow in his creative foot-steps. One of Walt Disney's most noted contributions to the world is the first theme park ever to come into creation: Disneyland. Disneyland has been the model for other theme parks around the world, but yet has still remained the most successful of them all. This paper explores the multiple reasons that Disneyland has managed to stay on top all of these years, including the real-life inspiration for the park, the Disneyland themes, the Disney inventions, and the overall Disney experience. It also covers the many concepts that other theme parks, including Knott's Berry Farm and Universal Studios, have attempted to replicate and why they have not been as successful for them as it has been for their Disney counterpart.

Through much encouragement from her best friend and her boss, Kayhlen eventually gets up the courage and the confidence to ask out her guy, but she needn't have worried about it in the first place. Porter, Katelyn Nina Porter Faculty mentor: Jennifer Duis, College of Engineering, Forestry and Natural Sciences (CEFNS) Characterization of Students’ Quantitative Reasoning Skills in Chemistry As of 4-19-13 UG Symposium Presentation Abstracts The method in which students interpret knowledge has been a question circulating education professionals since the creation of the modern school system. Our research aims to better understand and characterize how students’ quantitative reasoning skills develop in their college general chemistry coursework in order to improve the course instruction. The use of graphs and tables as a teaching tool is common practice. Our research indicates that the ability to apply previously taught chemistry concepts such as density, and recognizing what is being held constant or is constant in the mathematical relationship is difficult for students. The presentation of these concepts in a table versus graphical format may alter the students' ability to apply them. Potential items and qualitative analysis of students’ developing quantitative reasoning in chemistry will be presented.

More recently, in the past several hundred years, food has become a symbol for culture and identity. There is an integral understanding by many people that certain cultures ban specific food items from consumption for religious or spiritual, ethical, or health reasons. In the United States, however, there appears to be a large stigma surrounding dog, horse and human meat. Many of the food taboos in the United States originate from our domestication of animals. Qian, Junfeng Qi Wang, Shiyu Wang Faculty mentor: Robin Tuchscherer, College of Engineering, Forestry and Natural Sciences (CEFNS) Prestressed Concrete Institute Big Beam Design Student Competition Team 2 The PCI Student Education Committee, one branch of the PCI Committee, is inviting students to participate in the Engineering Student Design Competition for the 2012-13 academic years. Each student team must work with a PCI Producer Member to build a precast-pre-stressed concrete beam which is 20 ft. long and tested as an 18 foot span. The beams will be tested and prizes awarded for best performance in the stated areas. Students must discuss both the structural design and the concrete mix design for the beam. The contest begins August 15, 2012 and ends June 15, 2013. All beams must be fabricated and tested within this time frame. A student team of 3-4 members is optimal, but teams of any size may participate. Team 2 must make sure the design load is between 32kips and 39kips which is required in the contest rules. In addition, the beam must resist load primarily through flexure. Trusses, arches and other non-flexural members are prohibited. Quinn, Courtney Faculty mentor: Maxine Janis, College of Health and Human Services (CHHS) NAU Campus Community Collaboration in Mainpat India Being in India allowed Northern Arizona University’s dental hygiene students to work in conjunction with a local Arizona dentist. The dentist gave assistance when needed, but mainly let the students be as hands on as a possible and put his full trust in the team.

Individuals suffering from CTE experience a progressive decline in memory and cognition, often experience depression and other emotional disturbances. CTE has been considered responsible for suicidal behavior, poor impulse control, aggressive and violent behavior. Clinically, CTE can lead to Parkinson’s, dementia or ultimately death. It is believed that accumulations of hyperphosporylated tau and TDP-43 proteins in the brain form as a result of repeated trauma. These proteins are thought to be the cause of CTE. With more research and exploration, researchers will be able to help protect individuals against the disease and develop methods of treatment for those who are already suffering from the disease, and possibly save lives. Objective: To research the prevalence of CTE in modern day sport and seek information on how to prevent, diagnose and treat the disease. Results: In those individuals whose brains have been given to researchers to evaluate for cause of death and possible CTE, a high percentage of them have returned positive for CTE. These brains also have notable tau-protein hyperphosphorolaytion, beta-amyloid deposits and TPD-43 protein deposits. Conclusion: With research showing that repetitive concussions are the cause of neurodegenerative diseases later in life, it is important to evaluate and treat every mild traumatic brain injury with scrutiny. The degeneration of the brain is serious as it progresses and could lead to death. Quiver, Melanie Melanie H. Quiver, Kevin P. Drees, Paul S. Keim, Ruby Hammond, Jeffrey T. Foster Faculty mentor: Jeffrey T. Foster, College of Engineering, Forestry and Natural Sciences (CEFNS) Avian Malaria Prevalence in Hawaiian Birds Avian malaria is an infection of birds caused by the haematozoan parasite <Italicize>Plasmodium relictum<Italicize>. This blood parasite, along with its mosquito vector, was introduced to the Hawaiian Islands in the 1800's. Since then, avian malaria has been a leading factor in the decline and extinction of numerous native bird species in the islands. In this study, DNA was extracted from various Hawaiian bird blood samples from the island of Kauai and screened for the presence of malaria parasites. Presence of these blood parasites was determined using haematozoan-specific primers and conventional PCR methods to detect parasite presence. In a population of birds not believed to be exposed to malaria, we detected a high prevalence of malaria infection. This suggests that Kauai populations of birds from new areas are contracting this disease and may soon be threatened with high levels of disease caused mortality. Raber, Sarah As of 4-19-13 UG Symposium Presentation Abstracts Faculty mentor: Russell Benford, Nashelly Meneses, Stephen Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) Evidence of Selective Breeding and Habitat Use in Lambis lambis Spider conchs (Lambis lambis) play an ecological role in controlling macroalgal growth. Unfortunately on Saipan, overharvesting of L. lambis has negatively impacted their population. Little is known about their life history concerning sexual dimorphism and habitat preference. To characterize sexual dimorphism, I measured shell size, digitation length, digitation angle, and presence or absence of curved digitations. In addition, to determine if spider conchs prefer a specific substrate, I quantified their abundance on seagrass, coral reef flats, and reef rubble. Female shells were larger than male shells (N=41, F-ratio=8.15, P=0.007). They also had longer (N=29, F-ratio=5.61, P=0.02) and curved anterior digitations compared to males (N=41, X²=7.3, P= 0.007). Spider conchs were significantly more abundant on coral rubble substrate (N=12, X²=7.49, P=0.02). These findings suggest L. lambis exhibit reverse sexual dimorphism and reef rubble is the preferred substrate. This information might be beneficial for habitat management and implementation of captive breeding programs. Rains, Allison Faculty mentor: Jennifer Musial, College of Social and Behavioral Sciences (SBS) Regulating Sexuality: How American Law Serves to maintain Heteronormative Sexualities I will be examining sexuality and the law. I will begin by describing what one scholar has termed the “sexual hierarchy” where certain sexualities and subsequent expressions of sexuality are deemed socially acceptable and to what degree. From there, I will explore the historical forces that have shaped sexual law in America, namely religion. I will then use these findings to determine in what way they shape current U.S. laws that regulate the prohibition of oral sex in certain states, the prohibition and criminalization of prostitution, and the prohibition of gay/lesbian marriage. I will explain the laws that govern each of these forms of sexuality, explain how the law criminalizes/prohibits them, and explore to what extent these laws are robbing individuals of rights and freedoms. Ramirez, Brittany Faculty mentor: Jennifer Musial, College of Social and Behavioral Sciences (SBS) Femininity Analyzing the intersections of femininity. With different cultures, comes different beliefs of what is "feminine". The definitions of femininity are believed to be different with different ages, what about race and ethnicity? Within race and ethnicity a culture is born and the "norm" is created. Intersectionality plays a key role on the various ideas of what a woman is expected to do to be considered "femme". Ray, Ryan As of 4-19-13 UG Symposium Presentation Abstracts Faculty mentor: Cindy Browder, College of Engineering, Forestry and Natural Sciences (CEFNS) Development of a More Efficient Synthesis Method for Myriaporone 4 Many naturally occurring molecules show great promise in the fight against cancer and infections. The search for new medicinal compounds has often turned to nature for new lead drugs that may become a cure for these maladies. Myriaporone 4 (M4) is a naturally occuring molecule found in coral that shows promise as an anticancer agent. M4 is, however, very rare in nature and cannot be harvested efficiently and without causing significant ecological damage. Synthesis of this molecule avoids these problems. Previous syntheses of M4 were very time consuming and the goal of our research is to find a more efficient synthetic methodology. In order to synthesize the central portion, or core, of the M4 molecule, we are making use of intramolecular nitrile oxide cycloaddition (INOC). This INOC reaction forms a 2-isoxazoline that will make a suitable substrate to synthesize structures similar to the M4 molecule. This process converts a molecule containing an ester linked alkene and nitro group into a cyclic 2isoxazoline using mild conditions. During this process new carbon-carbon and carbon-oxygen bonds are formed within the molecule. The substrate for the INOC reaction is formed via an ester synthesis joining a carboxylic acid containing alkene and a nitroalkane. Conditions for a successful INOC reaction are currently being explored. Rebecca, Largent Faculty mentor: Jennifer Musial, College of Social and Behavioral Sciences (SBS) Homosexuality and the Military This research will analyze sexuality, heteronormativity, and the history and policy of homosexuals serving in the United States military. It will focus on the don’t ask, don’t tell policy, its history and current policy regarding same sex couples. The history will focus on policy created to prevent homosexuals from serving openly, and what discharges for homosexual conduct meant for service members. I hope to provide information about the repeal of don’t ask, don’t tell and official policy lifting the ban on homosexuals serving. The research will also focus on current policy changes that have shifted to better serve same sex couples and what restrictions are still in place. I hope to also present ways in which equality of marriage would help benefit same-sex couples serving in the military. Rees, Patricia Bo Stevens Faculty mentor: Rich Hofstetter, College of Engineering, Forestry and Natural Sciences (CEFNS) Erwinia tracheiphila as a Biological Control of Canada Thistle (Cirsium arvense) Cirsium arvense is an aggressive invader from Europe. Commonly known as Canada Thistle, this perennial weed is a nuisance for agriculture and livestock industries, infesting tilled and overgrazed land. So far no biological control agent has effectively managed the spread of C. As of 4-19-13 UG Symposium Presentation Abstracts arvense. Synthetic biology gives us a new approach to this problem. Any source of genetic code is now a potential source of information for the manufacture of a target specific bacteria. Erwinia tracheiphila is a pathogenic microbe known to cause bacterial wilt in cucurbits. It is vectored into the xylem of C. arvense by a non-specific host, the striped cucumber beetle (Acalymma vittatum). The specific gene that encodes for bacterial wilt could be identified and sequenced. If Canada thistle is susceptible to bacterial wilt, this may provide a means to create cheap and simple controls, eliminating non-target effects that plague other biological control methods. This study is an investigation into the possibility of E. tracheiphila as a source of genetic material for use as an engineered biological control agent against C. arvense. Two approaches were used to test the hypothesis that E. tracheiphila causes bacterial wilt in C. arvense. 1) Using PCR and DNA sequencing, we tested for the presence of E. tracheiphila by culturing bacteria from wilted samples of C. arvense. We anticipate verification of E. tracheiphila within these samples. 2) Inoculation of C. arvense with E. tracheiphila (ATCC# 33245) with observation of wilting symptoms followed by reisolation of the pathogen from wilted plants. Successful verification of this causal relationship could lead to an efficient biological control, alleviating the need for energy intensive and unsustainable methods of mechanical and chemical control.

The current method for insulin administration varies between users; however, all current methods are prone to human error through improper measurement inside the syringe or data recording. Feline patients are particularly difficult to dose proper due to the small amount of insulin required. Apple Developer Tools along with OpenCV visually track a syringe in real time and estimate plunger to prong distance for volume calculations. The application successfully tracks and measures the volume in the syringe. Further testing is required to establish the error in measurements using the built in iPad camera. The application promises to ease the book keeping burden of diabetes treatment. Reynolds, Robert As of 4-19-13 UG Symposium Presentation Abstracts Maria Espinola-Romero Faculty mentor: Niranjan Venkatraman, College of Engineering, Forestry and Natural Sciences (CEFNS) BeagleBoard Capstone Redesign Contaminated water harms ecosystems and the people who drink it; however, with proper detection the pathogens in the water can be accurately identified, and the water can be effectively treated. A difficult task for people, who live near non-potable water, or those living in rural areas, is to test their water inexpensively. The BeagleBoard XM is a small processor with standard features that can be found on most laptops and computers today; consequently, some components are unnecessary and add bulk to the design that is specific to water contamination detection. We addressed this challenge by adding and removing components from the multipurpose BeagleBoard XM so that it would be optimized for this application. The optimized BeagleBoard adds Wi-Fi, GPS, a webcam, and a smaller LCD, in a smaller volume. Software testing determined the compatibility of the new components with the BeagleBoard's operating system to provide a cost effective product with ease of use to test water contamination. We will provide a schematic for the optimized BeagleBoard, and a documented test analysis of the potential components for the board will be included in our report. Rice, Johnathan Faculty mentor: Scott Anderson, College of Engineering, Forestry and Natural Sciences (CEFNS) 2700 Years of History in Coastal Sagescrub, Southern California MOD III pond is located near Santa Barbara, California and provides a unique opportunity to study a marsh/wetland area in southwestern California. Lake and marsh records for the southwestern United States are not completely known due to the recent increase of human development combined with the arid environment. A fire regime associated with MOD II pond was reconstructed by separating charcoal particles from a sediment core that was obtained in 2009. The isolated charcoal particles were counted and entered into the program ‘CharAnalysis’, which uses a running average of the counted charcoal particles to isolate fire events. The identified fire events were then correlated with a vegetation record that was already reconstructed based on pollen that was extracted from the same sediment core. No fires were observed in the upper portion of the sediment core. The lack of fire is correlated with an increase in grasses that are common for grazing and a proclamation by a Spanish Governor in 1793 ordering fire suppression in the area. Fires occurrences below this portion of the sediment core have been correlated with algae that are known to flourish during fires. The bottom of the sediment core, at approximately 2700 years b.p., shows a higher fire occurrence. The As of 4-19-13 UG Symposium Presentation Abstracts reconstructed record for this area can now be used to help guide future management practices and contribute to the understanding of human interaction in areas that have seen recent population growth. Rice, Johnathan Carly Farr Faculty mentor: Scott Anderson, College of Engineering, Forestry and Natural Sciences (CEFNS) Using GIS Data to Examine the Health of the Coconino Forest Over a Ten Year Period The Coconino National Forest in northern Arizona has had varying degrees of anthropogenic interaction for the past 200 years. The focus of this study was to analyze the health of the forest over a ten year period, from 2002-2012. Bark beetle infestation, ponderosa pine population, and fire occurrence were considered when determining the health of the forest. Two maps were constructed using ArcGIS to create polygons showing where the aforementioned factors occurred. The first map showed where the factors occurred in 2002 and the second map showed where the factors occurred in 2012. The map area was chosen to represent a general cross-section of the forest that included wooded regions and a riparian environment. It was found that ponderosa pine populations increased as a result of grazing being mitigated in the area. The bark beetle infestation increased along with fire occurrence. Restoration efforts in this area have been largely responsible for the changes in forest health concerning the increase in ponderosa pine. However, a correlation can be made with increase in anthropogenic interaction, climate change, and the increase in both bark beetle infestation and fire occurrence. The knowledge gained from this study can help to guide future restoration efforts and help understand the effects of climate change in the Coconino National Forest. Rice, Rebecca Giovanna Fotino, Katherine Kurpierz Faculty mentor: Brant Short, College of Social and Behavioral Sciences (SBS) Helping Granny Cross the Street: How Stereotypes of Seniors Keep Them in Poverty This research paper aims to analyze the effect rhetoric has on the topic of poverty and examines the effects of stereotypes on senior citizens. Specifically, this study demonstrates how stereotypes can cause seniors be subjected to poverty. Using the fantasy theme style, we researched how stereotypes created about seniors can gain broad support in public thought. As the mass media and the public perpetuates these stereotypes, seniors suffer. Seniors become susceptible to the self-fulfilling prophecy, and begin to define themselves using the stereotypes to which they are exposed. These internalizations can prevent seniors from being able or willing to attain employment or other outside help for their poverty. By changing the ways in which we stereotype seniors, we empower them and can help them move out of poverty. Richardson, Joshua Faculty mentor: Francis Smiley, College of Social and Behavioral Sciences (SBS) As of 4-19-13 UG Symposium Presentation Abstracts Problems in Public Education: Why High Schoolers Drop Out My presentation concentrates on the difficulties many high school students of different cultures and races face that lead them to drop out. Many factors can accompany this including teachers not understanding cultures of Native Americans. Other factors may include bullying, inappropriate rumors and false ideas about their cultures, and lack of educational support for Native students. Dropout rates in this group category have reached 40 percent and are still rising. This presentation is also meant to bring awareness to anyone who has not been made aware of this growing problem in the Southwestern United States, as it shows mostly in the state of Arizona. I have learned that in 2007, the dropout rate for Native American students was at its highest at 19.3 percent, compared to the highest percentage of 91 percent for Asian/Pacific Islanders in the 2007-2008 Freshman year. Native students continue to suffer lack of jobs like other dropouts do as their unwillingness to graduate seems to prevent them from getting the right job to care for themselves and their families. With this presentation, people will realize how their children will affected by their choice to drop out. Richter, Bethany Stormie Faculty mentor: Lauren Berutich Campus and Community Based Action Research Teams FYSeminar Program, University College, University College Action Research and Engaged Learning: Immigration ART Fostering just and sustainable communities in northern Arizona through engaged learning, community partnerships, and action research A component of CRAFTS (Community Reengagement for Arizona Families, Transitions, and Sustainability), the Campus and Community Based Action Research Teams (CBARTs) create dynamic intergenerational hands on learning communities, bringing first year seminar students, returning undergraduates, masters students in the sustainable communities program and community partners into a collaborative relationship. There are over 10 Action Research Teams, a range of 250 to 500 undergraduate students and 20 SUS grad students participating both on and off campus in the areas of social, environmental, and economic justice issues. FYSeminar courses offered with an ARTs component exposes students to a unique pedagogical approach to hands-on, experiential learning of which content, skill set development, action research and student engagement are fruitfully intertwined and connected. This spring, each team is posed with the question, “What is Action Research?” and how does this work connect to community engagement, civic learning, and collaboration. Each poster will answer this question and share how Action Research has engaged students in hands-on experiential and civic engagement throughout the semester and year.

The field of phylogenetics is undergoing continuous improvement. Where phylogenetics once used morphology, protein similarities, and genes as its primary tools, it now uses whole genome sequences. The promulgation of whole genome sequencing can lead to better defined phylogenetic relationships, which, in turn, allows for better evolutionary understanding of phenotypic attributes. Here we discuss a phylogenetically based hypothetical ancestor reconstruction process (HARP), which can be used to reconstruct the genomes of extinct common ancestors. We demonstrate this process by reconstructing the genome of the common ancestor of the clonal organism Coxiella burnetii (Cb)—the causative agent of Q fever. By means of HARP, we compared extant whole genome sequences of Cb to identify regions of genomic similarities and mutations. The genomic regions where mutations are present were regressed to their inferred ancestral state by means of phylogenetically guided cross-strain comparison. By reconstructing the extinct hypothetical ancestor, we have gained insight into the evolution of Cb. For example, genome reduction has occurred in the species and a functional comparison of lost genes suggests that the ancestor survived in a more variable niche. HARP thus allows us to better understand the evolution of phenotypic qualities, and speculate about the environmental conditions and selective pressures that led to their evolution.

As of 4-19-13 UG Symposium Presentation Abstracts Roberts, Daniel Faculty mentor: Elizabeth Brauer, College of Engineering, Forestry and Natural Sciences (CEFNS) Mentor Graphics Automation Efficient time usage for simulations is an important concept to the engineering field. Engineers not effectively utilizing time will fall behind on various projects they seek to complete because much time is be wasted in the simulation phase. Task automation is one tool used to reduce the amount of time spent on tasks. This research project investigates the use of Tool Command Language (Tcl) in the automation of simulation analysis in the Mentor software used in the Electrical Engineering department at Northern Arizona University. The main two tasks to be automated were calculating propagation delay and analyzing the voltage transfer characteristic in standard CMOS circuits. The EZWAVE package of the Mentor Graphics software was automated using Tcl scripting, while still employing the mathematical functions and tools native to the software. The result is that the user is able to commence many simulations and collect all of the data rapidly. The use of Tcl prevents the user from having to manually perform each simulation one at a time. Roberts, Cisneros, Sydney, Toni Toni Cisneros Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) The Correlation Between Self-Perception and Social Interaction Self-perception has been found to have an effect on social interactions. Self-esteem has previously been researched and found to have a positive correlation with sociability. The correlation between self-perceived attractiveness and self-esteem of female undergraduate college students was assessed with the likelihood of approaching male undergraduate students based on attractiveness. Participants were exclusively female undergraduate college students in PSY302W. All participants were assessed through surveys on self-perceived attractiveness and self-esteem. After the surveys were taken the participants were shown pictures (one attractive male, one unattractive male) and were asked to choose which one they would feel more comfortable approaching. It is hypothesized that the participants with higher self-perceived attractiveness and self-esteem will be more likely to approach the attractive male. The results could provide evidence that self-perception correlates with comfort when approaching others.

Rodriguez, Ricinda Faculty mentor: Abbe King, Laura Crouch, College of Health and Human Services (CHHS) Contact Precautions and Adverse Patient Effects Contact precautions in the hospital setting are important for controlling and preventing the spread of Multi-Drug Resistant Organisms. In many situations patients are placed in a private room setting with signs on the door stating these individuals are isolated. Personal protective equipment (gowns, gloves, and mask) are donned before entering the room. Current policy at Flagstaff Medical Center identifies individuals with (or a history of) MRSA, VRE or other drug resistant organism by flagging them with a Disease alert in the computer system. Once identified, the patient will be placed in isolation until the organism can be ruled out. Patients will remain in insolation until results of cultures are obtained. No recommendation from the CDC can be made regarding when to discontinue Contact Precautions, leaving individuals isolated for long periods of time. My research found placing patients in an isolation setting have been associated with adverse patient outcomes. These adverse outcomes include fewer interactions with healthcare workers and physicians and a decrease in patient satisfaction. It some situations it can cause patient psychological and physical distraught.

Rolik, Scott Faculty mentor: Dean Smith, Franke College of Business (FCB) Rainfall vs Economic Growth My research is to determine if the economic growth of major metropolitan statistical areas relates to their population growth, indigenous rainfall, annual water consumption, land area, and population density. By gathering data from the past century, I will determine if the above independent variables do in fact influence economic growth. Once that information is established, I will be able to answer two questions. First of all, is it economically feasible to be urbanizing in arid locations of the western United States? I will also determine if the majority of our country’s population is settling in locations with high or low rainfall and if westerners are in fact breaking away from the norm of living near water.

Roof, Karah Dr. Nashelly Meneses Faculty mentor: Russell Benford, Nashelly Meneses, Stephen Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) Predation of the Small Giant Clam (Tridacna maxima) in Saipan Giant clams are keystone species that are being overharvested in Saipan. Many of them have brightly colored mantles, which may make them more vulnerable to predation. To determine if small giant clams (Tridacna maxima) are harvested in a sustainable manner, I compared the sizes (an indicator of age class/sexual maturity) of live clams in the Saipan lagoon and dead clams in harvest piles. Also, to determine if mantle coloration has an effect on survivorship, I looked for a significant association between mantle coloration and age class, an indicator of survivorship. A Wilcoxon Test showed that the size of harvested clams is significantly different than the sizes of live clams (N = 173, Z = -3.66, p=0.0002). Clams are being harvested before they are sexually mature. In addition, a G-Test showed that there are significant differences in the age classes between mantle patterns (N=60, G=35.95, p=0.01). The more brightly colored clams are not surviving to sexual maturity. Giant clams are not being harvested in a sustainable manner. This As of 4-19-13 UG Symposium Presentation Abstracts could be detrimental to the viability of the population. Implementing size and quantity harvest restrictions, and reinstating an aquaculture program are ways that Saipan can help recover its clam population.

There is a discrepancy regarding the practice of pre-inflating a urinary catheter balloon prior to insertion into a patient to test for integrity of the balloon. Some sources state that such a practice is necessary to determine if leaks are present in the balloon; other sources state that such a practice causes structural changes to occur in the urinary catheter. Our poster aimed to determine which practice was safer and most effective. We have determined where current evidenced based practice lies in the issue of whether to inflate or not to inflate. Saltzman, Marissa Spencer Ropte Faculty mentor: Apichai Tuanyok, College of Engineering, Forestry and Natural Sciences (CEFNS) Relationships of Genomic Composition and Virulence Within B. pseudomallei in Soil from North-East Thailand. Burkholderia pseudomallei, a Gram-negative bacterium that thrives in soil and water, is the causative agent of melioidosis. Melioidosis is tropical disease which is endemic in Southeast Asia and northern Australia. It causes an on-going issue with no vaccine and high mortality rates in humans which makes B. pseudomallei considered to be a possible bioterrorism threat. It is not known whether all environmental isolates can cause disease. Thus, isolates from an intensively As of 4-19-13 UG Symposium Presentation Abstracts sampled site in Thailand were examined for genetic diversity and the ability to cause disease in an animal model. In this study, we examined the presence and genetic diversity of B. pseudomallei in soil samples, collected from Northeast Thailand, during the dry season in 2007. At least 400 B. pseudomallei strains were analyzed for genetic diversity using multi-locus sequence typing (MLST). Interestingly, 14 unique genotypes were identified in a single soil sample (INT2). In the surrounding intensive sites, B. pseudomallei was not as prevalent as previously found in INT2. Due to high genetic diversity within the sampled population, a BALB/c mouse model was used to monitor rates of infection and illness by 30 representative isolates. The study has confirmed that not all tested isolates caused disease in mice. Based on the mortality rate, further genetic analysis was conducted on genomic islands (GIs) to determine if any relationship between genomic composition and virulence were present. Our results suggest that not all strains of B. pseudomallei cause disease due to the differences of their genomic compositions. Sanchez, Briana Lance Lopriore, Chantal Kescoli, Erinn DeMarco Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) The Food and Mood Connection This study examines the relationship between diet and depression. The independent variable was the amount of healthy versus unhealthy food consumption in a college population. The sample consisted of 125 undergraduate students in a mountain city located in the southwest region of the United States. Participants took a self-report study to indicate the amounts of healthy versus unhealthy food consumed in a 24 hour period. This was then related to the scores reported on the Beck's Depression Inventory. The relationship discovered within the study indicated higher amounts of healthy foods were associated with lower scores in the BDI, while higher amounts of unhealthy foods correlated with higher scores on the BDI. This study found that depression rates were found to have a positive correlation with a consumption of unhealthy foods. Sanchez, Daniel Faculty mentor: Jeffrey Foster, College of Engineering, Forestry and Natural Sciences (CEFNS) Assessment of phylogenetic resolution in a diverse panel of Pasteurella multocida isolates using variable number tandem repeat (VNTR) analysis Avian cholera is an extremely destructive wildlife disease caused by Pasteurella multocida, a host density-dependent bacteria that swiftly cause thousands of waterfowl mortalities each year in North America. In this study, we tested a diverse panel of P. multocia isolates to assess phylogenetic diversity in highly mutable loci known as variable number tandem repeats (VNTRs). A total of 15 VNTR markers were tested against 60 globally acquired samples of P. multocida, collected from a diverse sampling of avian hosts, bacterial serotype, sequence type, and collection location. Genetic variation was observed when comparing samples collected in distant geographic proximity, which was to be expected. Results then provided evidence that using VNTR markers to compare distantly related, geographically dispersed, and host-specific As of 4-19-13 UG Symposium Presentation Abstracts genotypes may be sufficient in identifying phenomena such as avian host-crossover and other stochastic ecological interactions leading to deadly outbreaks. Sands, Will Josiah T. Huggins, Casey Ellito, Kimmi Philips Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) The Effects of Sleep and Depression The study of sleep and depression is essential to research because it is important to understand the possible link between the variables of sleep and depression. The study will not only clarify knowledge, but also relate this information to the public. The objective of the study is to find a correlation among sleep quantity and qualify as well as depression. The study will add to current research by studying the differences and similarities among correlations of sleep quantity and quality of sleep in relation to depression; as well as adding to current research by using three different methods to accurately measure variables: Becks Depression Inventory, Pittsburgh Sleep Quality Index, and finally a few short questions designed by researchers who's primary focus is studying sleep quantity. The survey was combined into a packet and given to Northern Arizona University psychology 302w during normal class hours. The participants consisted of both men and women ranging in age of 18-22 while the majority consisting of European-American women. The anticipated results include a positive and negative correlation. That is, an expected positive correlation among sleep quantity and depression, meaning depression could be related to many hours of sleep; the negative correlation is expected among sleep quality and depression, showing that the more times a person may wake up during the night, the more likely hood they are to be correlated with depression. Saucedo, Johanna Faculty mentor: Anne Scott, Honors Program Bond Girl or Bond Animal? Ian Fleming tends to associate animalistic or instinctive behaviors and qualities with women in his espionage novels From Russia, With Love, Dr. No, and Goldfinger. In the films adaptations, their behaviors are reduced to the point where they are purely bodies present for Bond’s enjoyment. Scandura, David Faculty mentor: Anne Scott, College of Arts and Letters (CAL) Raoul Silva: Reinventing Evil in Skyfall Among its many reinterpretations of the James Bond franchise, 'Skyfall' also brought a new villain to the franchise unlike any we have seen before: Raoul Silva. Javier Bardem's thrilling performance creates a new Bond villain altogether; a villain with an intriguing past, a complex personality, and a personal vendetta that will shake James Bond's world to the core. As of 4-19-13 UG Symposium Presentation Abstracts Using discussion, film clips, and analysis, this presentation will explore how the "Bond villain" has moved into the 21st century through the lens of Bardem's performance of Silva. The world domination schemes, white Persian cats, and high-tech doomsday machines are long gone. In a world where our enemies don't wear uniforms or are restricted by lines on a map, the villains of the Bond franchise have become equally complex, layered, unique, and dynamic antagonists to the British super spy. Silva is the perfect representation of the "new Bond villain," and this presentation will explore Silva's character, master plan, and Bardem's wonderful interpretation of the character in order to illustrate this point. Schellinger, Robert Faculty mentor: Thomas Paradis, College of Social and Behavioral Sciences (SBS) Impacts of Ski Tourism on Smaller Communities in the American West This presentation consists of the impacts of Ski Tourism on smaller communities in the American West. The research is focused on Sunrise Park Resort, located in the White Mountains of Arizona. The communities near Sunrise Park Resort consist of Pinetop-Lakeside, Springerville-Eagar, and Show Low, Arizona. . The smaller communities will be conducted on research of whether Ski Tourism is a big factor for seasonal tourism. The effects of Ski Tourism will consist of the long term impacts, short term impacts, and the seasonal impacts on the nearby communities of Sunrise Park Resort. The impacts will consist of economic development based on ski tourism. Schmiester, Amanda Faculty mentor: Dorothy Dunn, College of Health and Human Services (CHHS), Honors Program Communication strategies and stress management techniques for unpaid caregivers of individuals with dementia or Alzheimer’s disease Last semester, I worked with Dr. Dorothy Dunn, faculty for the NAU Nursing Program, to better understand the role of the unpaid caregiver. Unpaid caregivers are those who voluntarily care for their family, friends, or neighbors. My research specifically focused on those with loved ones who have been diagnosed with any form of dementia. Many of these caregivers do not understand how to best communicate with their loved ones with Alzheimer’s disease and related disorders. The stress of this lack of communication and the role as the caregiver in general, can be incredibly rewarding; however, it can also be overwhelming, frustrating, and stressful. For this reason, I believe it is of utmost importance to develop coping strategies for unpaid caregivers. My instructor acted as a consultant for a support group newly founded at the Peaks, which is a senior living facility with a skilled nursing department and memory unit. I was able to observe a meeting. Through my observations and my research, I found several common themes among unpaid caregivers. I also developed a list of five stress relieving strategies I would recommend specifically for individuals in this role. As of 4-19-13 UG Symposium Presentation Abstracts Schroeder, Hannah Faculty mentor: Adam Hoffman, College of Arts and Letters (CAL), Honors Program Life Through My Lens What’s really interesting about photography is that it is considered both an art and a science; I feel that this is why photography is so interesting to me, because it appeals to both my scientific and my artistic sides. Photography is the art and science of using light to capture an image either digitally or via film. Photography is not only the process of capturing light and images, but also of capturing emotions, ideas, and moments in time that can never be retrieved. Photography is somewhat paradoxical in that, despite the fact that the literal and tangible moment itself is gone, it is still view able in the photograph. Photography is indeed the process of using light to capture an image, but to me, it's so much more. Scott, Jeremy Faculty mentor: Paul Helford, College of Social and Behavioral Sciences (SBS) Nose Bleed Nose Bleed is a short film. The goal of the film is to draw attention to the humanitarian crises being generated both inside and outside the U.S. as a consequence of the War On Drugs. Drugs have become so stigmatized over the last 40 years that it's is nearly impossible to have a rational public discussion on the issue. The great majority of politicians are unwilling or unable to bring up the topic. This is having a detrimental effect on our society. In spite of statistics that tell us that the more drugs are available now than ever before, incarceration rates in the U.S. are the highest in the world, drug laws are unfairly enforced throughout society primarily target the poor and minority communities, the status quo of drug law remains the order of the day. Prohibition creates a market for organized crime which is becoming more and more violent and lucrative as the stakes get raised.

Scott, Meaghan Faculty mentor: Zsuzsanna Gulacsi, College of Arts and Letters (CAL) Xu Beihong: the Traditional Roots of the Father of Modern Chinese Painting The formulation of an identity representative of China following the collapse of its imperialist tradition in 1911, and its transition into republicanism in 1912, required the cultivation of a new national aesthetic. Under the impact of great internal change, the Chinese were met with the challenge of preserving elements of their artistic heritage in the development of a modern As of 4-19-13 UG Symposium Presentation Abstracts identity. The position of the Chinese in the 20th century is perhaps best exemplified in the art of Xu Beihong who, for his conceptualization of this identity as a synthesis between the progressive Western attitudes toward the arts and the maintenance of the Chinese artistic tradition, is honored as the father of modern Chinese art. Through the adoption of the Western visual language of realism and foreign techniques, Xu Beihong effectively synthesized the modern currents of European painting with classical Chinese approaches to subject matter, artistic principles, and media. By the middle of the century Xu Beihong, having established a successful career as an artist, political activist, and art educator, exhibited his own and as well as other Chinese artists’ works across Europe and Asian with the intent of generating global appreciation for Chinese art, in addition to expose to a greater awareness of the Japanese occupation of China. In 1941, Xu Beihong’s desire to display a survey of influential Chinese artists before an American audience at the Denver Art Museum was almost actualized. However, it was the attack on Pearl Harbor merely a day before his departure to the United States and the escalating climate of WWII that ultimately deferred his plans. In homage to Xu Beihong’s legacy and accomplishments, between late 2011 and early 2012, the Denver Art Museum exhibited a collection of artist’s works entitled Xu Beihong: Pioneer of Modern Chinese Painting. The goal of this project is to evidence the traditional roots of the father of modern Chinese painting through the utilization of pieces from the Denver Art Museum exhibit in the comparisons of two iconic paintings of past Chinese masters housed at the Metropolitan Museum of Art,. Moreover, it explores Xu Beihong’s innovative approach to this artistic synthesis produced with the objective to reflect the Chinese people during a time of national struggle. Scranton, Rebecca Erelda Gene Faculty mentor: Priscilla Sanderson, College of Health and Human Services (CHHS) Understanding Hopi perspectives on tobacco use and cancer in both the Urban and Reservation populations through conducting focus group sessions The purpose of the focus groups were to obtain qualitative data regarding Hopi perspectives toward cancer and tobacco use. Seven focus groups were conducted- four on the Hopi reservation and three in Flagstaff, Arizona using the CBPR (Community Based Participatory Research) method. Preliminary results show that unless an individual was closely impacted by cancer, their desire to seek knowledge was limited. Participants perceived an increase in susceptibility in the past generation as well as an increase in awareness. Fewer urban participants shared personal stories about cancer. The urban focus groups seemed to be more influenced by media in their knowledge of cancer whereas the reservation groups shared their experiences. All focus groups associated cancer with negative emotions. Hopi people believe that traditional tobacco has a sacred meaning and is seen as a way to carry the Hopi prayers to the sky. Commercial tobacco, on the other hand, is connected to increased health problems and is seen as contaminated and impure. There is a mindset that people have to make their own decision to change and others can only do so much to help them. There were Tewa participants in the urban focus groups that felt that the purpose behind the smoking was more important than what was actually being smoked. Also, the women in the urban focus group were hesitant to voice an opinion about traditional tobacco because they felt like it was not their place.

Last December, students and faculty from the dental hygiene, education, forestry, physician assistant program, public health, journalism and nursing departments traveled to Mainpat, India to provide medical care to the Monastery as well as the surrounding refugee camps and local Indians. The overarching goal was to provide aid and preventative health care to the locals while documenting their story to bring awareness to their living situation. The students and faculty spent eight days in the camps, working on achieving discipline-specific goals as well as collaborating on interdisciplinary projects. Some unexpected challenges included working with a predominantly elderly age group, encountering communication barriers, and limited transportation. The health care groups also met political barriers when trying to provide care. Many group members were surprised by the difference in the level of health between the Tibetan refugees and the local Indians. By the end of the trip, the dental hygiene and nursing groups assisted 500 patients. The journalism group interviewed approximately 20 people from six of the seven camps. The public health and education groups spoke with community leaders and camp members from six of the camps and also helped out with the nursing and dental clinics. The forestry group measured several plots of land for research and the physician assistant professor along with Dean Schultz distributed Vitamin A doses and anti-parasitic medicine to the local children under five years old. Senini, Natalie Faculty mentor: Nashelly Meneses, Russell Benford, Stephen Shuster, College of Engineering, Forestry and Natural Sciences (CEFNS) The Effect of Sewage Effluence on Coral Reefs Sewage effluence negatively affects organisms and environments, including coral reefs. Healthy coral reefs are key in the success of coastal marine ecosystems in tropical areas. On the island of Saipan, a sewage outfall pipe dumps treated sewage effluence into the Saipan lagoon, a marine habitat surrounded by fringing and barrier reefs. To determine the effect of sewage effluence on fringing reef diversity, richness, and recruitment, I measured these factors at seven sites around the lagoon. I compared those values to the percent days of Enterococci violations, an indicator of the presence of sewage effluence. My results showed a significant relationship between richness (N = 21; Kendall's τ = -0.61; p = 0.003) and recruitment (N = 112; Kendall's τ = -0.24; p = 0.001) and the percent days of Enterococci violations only. Sewage effluence does not seem to affect the diversity of fringing reefs in Saipan, it has a negative effect on fringing reef richness and recruitment, which can eventually cause an overall decline in diversity. A decline in coral reef richness and recruitment could be prevented by 1) using alternative water treatments, 2) As of 4-19-13 UG Symposium Presentation Abstracts creating a buffer zone when planning sewage outfall pipes, or by 3) having sewage outfall pipes located in areas where they would not affect coral reefs. Shainin, William Faculty mentor: Dean Smith, Franke College of Business (FCB) Behavioral Economics and Water Markets The neoclassical economic model assumes that consumers are perfectly rational, and effectively maximize constrained utility on the basis of complete information. Research in behavioral economics suggests that individuals often make mistakes in logic, and these mistakes may be exacerbated in the case of markets for goods in which non-market valuation is a stronger determinant of allocation. This research investigates the applicability of the behavioral economic model in analyzing the market for water. Shan, Junyi Dr. Chun-Hsing Jun Ho, Darius Ishaku Faculty mentor: Chun-Hsing Jun Ho, College of Engineering, Forestry and Natural Sciences (CEFNS) The Pervious Concrete Research The project is to help Dr. Jun Ho with the development of the pervious concrete mix design formula that can be used in cold climate zones, namely in Flagstaff. The research involves specimen productions and laboratory experiments. If the results from laboratory testing are satisfied, the university will adopt the mix design formula and implement it on campus. The ARD (Applied Research and Development) building parking lot pervious concrete pavement failure in 2012 is the reason why the university is initiating the research; the ARD parking lot was the first installation (2007) in the state to use pervious concrete. However, due to cold weather affect and inadequate load capacity, the pavement failed and was replaced by asphalt pavement for safety consideration. The failure of the ARD pavement raised the interest of the university to develop an improved pervious concrete pavement, which may be used in more places on campus to manage the storm-water on site.

Sheble, Margaret Erin Carter and Kiran Haynes Faculty mentor: Jennifer McLerran, College of Arts and Letters (CAL) Reflections of Flagstaff: An Interactive Photography Exhibit For the current 2012/2013 academic year, students have worked hard to create Reflections of Flagstaff: An Interactive Photography exhibition. The exhibition’s main mission was to promote interaction between NAU and the larger Flagstaff community, and to provide opportunities for reflection on the multiple histories and contemporary realities of this unique place. The individuals who participated in this exhibition made it possible by submitting their photos and sharing their stories. Visitors to the museum space were asked to freely become part of the exhibition by sharing any thoughts, memories, or inspirations they have by writing on the gallery walls. The symposium presentation will outline the exhibition process from start to finish. Sheble, Margaret Faculty mentor: John Doherty, Anne Scott, Alyce Jordan, College of Arts and Letters (CAL) The Once and Future Mordred: The Great Betrayer in Art The middle ages were a complex time of war and famine, what some even refer to as ‘the dark ages.’ From this time legendary British hero, King Arthur, emerged who freed the people from the land and created the utopian kingdom Camelot. But this golden age could not last, as all good things must come to an end. Mordred, the bastard son of Arthur and his sister Morgana, enters the scene and brings about Arthur’s death and the ultimate downfall of Camelot. Mordred’s traditional role as villain has expanded into a character study of what is not desirable in a society and demonstrates the very human fascination with the act of betrayal Mordred embodies. The interest in betrayal can also be seen in the portrayal of another major medieval villain, Judas Iscariot. In the academic year of 2011-2012 I completed an undergraduate honors thesis titled “The Once and Future Mordred: The Great Betrayer in Art” in which I examined the question: ‘Must Mordred remain the villain within art to teach morals?’ To answer the question of whether or not Mordred must stay the villain, I analyzed the various historic movements in which Mordred’s character greatly changes in art. Shipley, Alysha As of 4-19-13 UG Symposium Presentation Abstracts Kelly Benderman Faculty mentor: Walter Vannette, College of Social and Behavioral Sciences (SBS) Advantages and Limitations of the Indian Child Welfare Act The Indian Child Welfare Act of 1978 was passed by the federal government as an attempt to keep Native American children with Native American families. This project approaches ICWA from an anthropological perspective, beginning with a thorough examination of the formation and implementation of ICWA in 1978. This project will also cover ICWA as it relates to child welfare policy. ICWA has created both advantages and limitations across the United States regarding the legal process that occurs when placing Native American children in permanent homes. Through the analysis of the advantages and limitations within the legal process which determines permanency for Native American children we can determine where changes in policy can be made in order to promote child welfare and preserve cultural heritage within Native American communities in the future.

Wagner Faculty mentor: Joseph Busch, College of Engineering, Forestry and Natural Sciences (CEFNS) Finding unique genomic elements in the bacterial pathogen Burkholderia pseudomallei through whole genome comparisons with closely related species Burkholderia pseudomallei (Bp) is a gram-negative soil bacterium native to Australia and southeastern Asia that causes the disease melioidosis. Developing diagnostic assays to detect Bp in environmental and clinical samples is a high priority due to the potential for this pathogen to be used as a biological weapon. To design diagnostic assays that are specific to Bp, it is imperative to avoid genomic regions that are shared with other closely related species (Bp nearneighbors). However, such genomic differences are poorly characterized and require a comprehensive genomic analysis of many related Burkholderia species. In this study, we cultured Burkholderia spp. from soil samples in the U.S. (n=36) on Ashdown’s agar and compared them to isolates cultured with the same methods (n=120) by our collaborators in Australia. We identified all soil isolates to the species level using DNA sequences from two genes, recA and 16S rRNA, and then performed a phylogenetic analysis to determine which species were most closely related to Bp. In the U.S., we identified eight Bp near-neighbor species, with most isolates (n=23) belonging to B. vietnamiensis. We then generated wholegenome sequences (WGSs) from phylogenetically distinct Bp near-neighbor isolates (n=5). All WGSs were compared with Bp isolates (n=150) to determine unique genomic components in Bp. We found 15 potential genes in the core genome of Bp that do not overlap with closely related species that could be targeted for diagnostic assays. This preliminary dataset shows promise for developing highly specific diagnostic tools for Bp detection. Shorty, Rochelle Faculty mentor: Michael Lerma, College of Social and Behavioral Sciences (SBS) As of 4-19-13 UG Symposium Presentation Abstracts Resolutions to Contemporary Navajo Policing American Indian police services originated approximately around 1869 when Indians were employed as police officers for the Iowa and Sac-Fox tribes in Nebraska, the Navajo Nation formed its own police headquarters at its own authority until 1959. Today, while many Navajos continue to live a simple traditional lifestyle — raising livestock or staying in close contact with their culture — the Navajo Nation is also dealing with the same modern 21st Century challenges as nearly every other Native or non-Native community in America. Police officers and employees complete duties very similar to those performed in most or all police departments in the United States with one major difference… The solutions to Navajo Nation “problems” vary among their government. However, there are three models identified which may exist in the Native American community: (1) the crime control model, (2) the community policing model, and (3) the political sovereignty model. Other than a model, it would be a sign of respect and recognition, as per the self-determination act, of the Navajo way of life if the federal government allowed the Navajo Nation to address their own problems within their boundaries. Navajos must control the law enforcement proceedings on their own reservation. Siclovan, Dina Keaton Henriksen, Austin Bell, Helena Herrera, Rob Atkins Faculty mentor: Geeta Chowdhry, College of Social and Behavioral Sciences (SBS) Modernity and Environment: A study of Air Pollution in China from 2000 to Present Day The literature on growth and development, often understood as modernity, has indicated that there is tension between securing economic growth and environmental security and sustainability. China is no exception. A major issue that has resulted from this tension in China is air pollution. For this research, we will focus on the issue of air pollution in this country. We will examine the history of air pollution, the regulations China has, current health consequences, the future impact of continued economic growth, and the measures that China is taking pertaining to air pollution. Throughout the paper, we will discuss whether the tensions between economic development and environmental security and sustainability are necessarily as oppositional as critics make them out to be. Is there a way out of this oppositional predicament? Silberschlag, Amanda Faculty mentor: Deborah Craig, College of Health and Human Services (CHHS) Study of Low-Level Lasers Many are familiar with modalities such as ice, ultra sound, and electrical stimulus, which all have their place in medicine; however they are unable to provide some of the healing aspects as low-level lasers are able to produce. Lasers are an apparatus that have been around for generations and originated in the United States in the 1960’s, but did not make its début in medicine until the 1980’s. The low-level lasers described in this paper received Federal Drug Administration (FDA) approval in 2002 and have been used in various medical settings. Lowlevel laser therapy is considered a relatively new modality in the world of medicine, and is used As of 4-19-13 UG Symposium Presentation Abstracts sparingly in athletic training. There are three major low-level lasers used in medicine, which include gallium arsenide (GaAs), gallium aluminum arsenide infrared semiconductor (GaAlAs), and helium neon (HeNe). Each type of laser can provide different therapeutic outcomes, which range from a shallow, to deep tissue penetration. Low-level lasers are a fairly new modality being used to treat a variety of athletes and in different settings because they are portable, non-invasive, and easy to use. Although the lowlevel lasers can be expensive, they are gradually making their way onto the sidelines of sporting events and being used as another option of treatment for athletes. Similar to other treatment modalities, low-level lasers have had mixed results in research studies, have been accepted gradually in the field of athletic training, and can affect injuries and athletes differently. An athletic trainer can use low-level lasers in conjunction with other modalities, or independently depending on the response. Sindelar, Audra Camila Scott, Miles Sorensen Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) How Video Recorded Emotional Expressions Affect Sexual Attraction The purpose of this study is to examine the effect of emotional expression on sexual attraction and determine whether or not this effect is moderated by gender. The researchers hypothesize that displays of happiness will result in higher ratings of sexual attraction by male participants than displays of confidence, shyness, sadness, or a neutral control. The researchers also hypothesize that displays of confidence will result in higher ratings of sexual attraction by female participants than displays of shyness, sadness, happiness, or a neutral control. In order to test these hypotheses, the researchers created five short scripts, one for each emotional expression, and video recorded one male actor and one female actor reciting these scripts. Participants of each gender were shown videos featuring the opposite gender and asked to rate the sexual attractiveness of each emotional expression. The current study seeks to extend previous research by using different materials and by considering, in part, largely unexplored emotional expressions. This study is important because the answer to how sexual attraction is affected by emotional expression has very practical, real-world applications; for example, mate attraction. Skilsky, Violet Faculty mentor: Adam Hoffman, Honors Program Toolset of Reconciliation: The Economies of Modern Native American Reservations The paper is about the economy of modern Native American reservations. It starts by giving a brief history from an economic perspective of the reservations. Ever since the non-native settlers came to America, they wrongfully assumed that everything was theirs. The tribes were treated as obstacles in the way of our “manifest destiny.” Since then, there have been policies switching back and forth between allowing the tribes limited sovereignty and forcing the tribes into “civilization.” Both are ineffective for the Native Americans and have resulted in their extreme poverty. With background and research to defend its position, the paper argues that the only way for Native Americans to have economic prosperity is to allow them to be self-governing as long As of 4-19-13 UG Symposium Presentation Abstracts as they adhere to the US Constitution. Instead of handouts that cause them to be dependent, we should offer them toolsets to create their own wealth. Private investors and businesses rarely thrive on reservations because of the unstable, inefficient tribal governments. If the US provided regulations that encourage business on reservations instead of inhibit them, the tribes could experience economic success. Slosky, Daniel Faculty mentor: David Trilling, College of Engineering, Forestry and Natural Sciences (CEFNS) Discovering Interior to Earth Objects Near Earth Objects are bodies whose orbits bring them close to the orbit of Earth. Interior to Earth objects are of particular interest and cannot be discovered using traditional nighttime telescopes as they face away from the sun. We are using data from the sun-looking STEREO spacecraft, from which we are able to successfully discover Near Earth and Interior to Earth Objects unseen from the Earth's surface. Interior to Earth Objects offer the opportunity for us to study material from elsewhere in the universe at a location close to home. They also carry a higher impact risk than any other type of body in the solar system. In analysis of our data, we will make conclusions pertaining to the size of the Interior to Earth Object population, taking the first step to understanding the posed impact threat. Smarzinski, Andrew Faculty mentor: Dean Smith, Franke College of Business (FCB) Agricultural Water Management Smith, Brett Faculty mentor: Zachary Smith, College of Social and Behavioral Sciences (SBS) How do YOU define Sustainability? This project’s objective was to analyze the international response to calls for sustainability and sustainable development since the release of the Brundtland Report in 1987 by the United Nation’s World Commission on Environment and Development (WCED). The goals of this study were to assemble and organize information about the international reaction to calls for sustainability, to improve my research and communication skills, and to better understand the state of global sustainability efforts. The methods of research used in the project included providing annotated bibliographies of government website content, completing word counts of National Sustainable Development Strategies, and review and analysis to a book under development by Dr. Smith. The conclusions of Dr. Smith’s work are first that the ambiguity of the definition of sustainability is both the concept’s greatest asset and its greatest flaw, because the definition can be manipulated to mean different things to different people. The second conclusion is that there is a need to develop a clear, exact and universally accepted definition for sustainability and sustainable development. This is because problems can arise when definitions As of 4-19-13 UG Symposium Presentation Abstracts inform policy-making, impact organizational operations or provide framework for decision making. The recommendations developed by Dr. Smith, to which my research was designed to contribute, are to develop a precise and universally accepted definition for sustainability that includes stricter adherence to the authority and limits of natural systems, and provides an increased emphasis on systems thinking. Smith, Matthew Faculty mentor: Kathleen Ganley, College of Health and Human Services (CHHS) Considerations for Functional Goals Following Total Knee Replacement Surgery Purpose: The purpose of this paper is to describe the knee range of motion (ROM) necessary to perform functional tasks such as squatting and kneeling, and to determine if physical therapists should focus treatment on regaining this needed ROM for patients undergoing total knee replacement (TKR) surgery. Methods: Two separate literature searches were performed on PubMed. Activities of Daily Living AND Knee Range of Motion were the key words for the first search, and Knee Range of Motion OR Outcomes AND Total Knee Replacement OR Total Knee Arthroplasty were used as keywords for the second search. Results: Two studies on functional knee ROM were reviewed to answer the first question reported the average necessary knee flexion ROM to perform a squat and to kneel was 111°-165° or full ROM. Five studies were reviewed to determine the maximum knee flexion ROM gained after undergoing a TKR. The maximum knee flexion reported was 150°, with 110°-132° being the average reported knee flexion ROM. Discussion: The data suggests that most patients undergoing total knee replacement surgery will not regain enough knee flexion range of motion to be able to squat or kneel without modifications. In regards to physical therapy, this suggests that interventions that focus on restoring > 135° of knee flexion range of motion may not be worthwhile. An example for context is provided involving a patient who returned to physical therapy 1.5 yrs after TKR surgery to regain the ability to squat and kneel. Conclusion: Patients undergoing total knee replacement surgery are not likely to be able to squat or kneel without modifications, and therefore, physical therapists should focus interventions on other aspects of care. Snelling, Sarah Faculty mentor: Ryan Kashanipour, College of Arts and Letters (CAL) Flagstaff's Mexican Community in the Early 20th Century Settlement of Flagstaff began in the late 1800's along the proposed path of the railroad. The rail builders and workers, as well as lumberjacks, mill workers and ranch hands were some of the town's first inhabitants and directly contributed to the growth of the railroad and lumber industries, and consequently the town. A large percentage of these workers were of Mexican origin and thus this separate community of migrant laborers became crucial to the development of Flagstaff and Northern Arizona. Their experiences include instances of embrace and neglect by the larger community, because their labor was so critical to the town’s economy but racism and xenophobia at times kept them at a distance. This population of workers and the families they would bring with them has been largely overlooked in the narratives of Flagstaff’s history. As of 4-19-13 UG Symposium Presentation Abstracts Sobek, Colin Kevin Drees, Paul Keim, Jeffrey Foster Faculty mentor: Jeffrey Foster, College of Engineering, Forestry and Natural Sciences (CEFNS) Optimization of DNA Extraction from Sediment and Bat Fecal Samples for the Real-Time PCR Detection of Geomyces destructans Geomyces destructans (Gd), the fungus responsible for White-Nose Syndrome (WNS), has killed millions of hibernating bats in eastern North America since its emergence in 2007. WNS spread from its epicenter in New York to include 20 U.S. states and 5 Canadian provinces, but the mechanism of transmission of the organism is still unknown. Gd has been isolated from the sediments of bat caves in areas with infected bats. Bats surviving hibernation in a WNS-affected cave can groom themselves to clear the infection, and Gd may therefore occur in bat feces. Both cave sediment and bat feces may serve as long-term reservoirs for the organism until bats are exposed to these materials at the onset of future outbreaks. In order to explore the potential of cave sediment and bat feces to harbor Gd, we modified a commercial soil DNA extraction kit (MO BIO PowerSoil DNA Isolation Kit) to optimize DNA yield and quality for purposes of rapid Real-Time PCR detection of Geomyces spp. (including G. destructans). Modifications included pretreatments with lyticase to weaken the cell wall of fungal cells and spores, and several methods to nullify PCR inhibition (multiple washes, template dilution, BSA) common in sediment and fecal DNA extracts. The optimized extraction method was used to screen for Geomyces spp. and G. destructans in cave sediments from outside of the North American WNS epizootic zone (Arizona, Texas), sediment from a bat hibernaculum in Slovakia, and bat feces from within the epizootic zone (NY, TN). Solheim, Jonathan Sophie Woodward, Austin Troth Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) Parenting Style and Sexuality Adolescents and young adults are at high risk for negative health consequences that stem from unsafe sexual practices. In this article, sociosexual activity and whether or not such activity is conducted in a safe manner will be examined, alongside the parenting environment in which one was raised in. Parenting styles in this study were defined as either authoritarian, authoritative, or permissive. The sample included mostly female, European-American students from Northern Arizona University. Current literature will be reviewed to give the reader a background in how parenting styles utilized in this study were derived, as well to show how this study builds upon prior knowledge of promiscuity and parenting style. A significant negative correlation is expected to be found between an authoritative parenting style and promiscuity.

High inclination KBOs are those with orbits between 20 and 90 degrees latitude above the ecliptic (the plane of our solar system). These high inclination KBOs had much more interaction with the large gaseous planets than their low inclination counterparts. By measuring the physical properties of these interacting KBOs, we can constrain the early history of the Solar System. We use archival data from the Hubble Space Telescope to study these KBOs. I present our results to date, which include finding objects and measuring the efficiency of our search.

As such, novel anti-fungal therapeutics are continually being investigated. An uncharacterized soil bacterium, K481-B101, from the Order Burkholderiales was shown to produce an antifungal, antitumor compound known as glidobactin that acts to inhibit eukaryotic proteasomes. A homologous glidobactin biosynthesis gene cluster was found on chromosome II of B. pseudomallei, the causative agent of As of 4-19-13 UG Symposium Presentation Abstracts melioidosis. The goal of this study was to analyze the glidobactin-like gene cluster in different Burkholderia species to predict the production of a glidobactin-like compound. Published and unpublished genomes from multiple Burkholderia species were used to identify the glidobactinlike genes. The study showed differences in the amino acid sequences within the gene cluster in five Burkholderia species. All B. pseudomallei isolates contained all five glidobactin-like biosynthesis genes but demonstrated variable numbers of tandem repeat (VNTR)-like sequences in one gene. B. mallei, the causative agent of glanders, contained all five genes but had insertion events in one gene that may disrupt the production of the antifungal compound. Non-pathogenic soil bacteria, B. oklahomensis and B. ubonensis, contained varied gene content within the cluster, while the gene cluster was absent in B. thailandensis. The presence and diversity of the gene cluster among Burkholderia species indicates that these species may produce different glidobactin-like compounds. Phenotypic studies of Burkholderia will be conducted to verify these genomic findings. Stevens, Bo Bo Stevens, Patricia Rees Faculty mentor: Richard Hofstetter, College of Engineering, Forestry and Natural Sciences (CEFNS) Erwinia tracheiphila as a Biological Control of Canada Thistle (Cirsium arvense) Cirsium arvense is an aggressive invader from Europe. Commonly known as Canada Thistle, this perennial weed is a nuisance for agriculture and livestock industries, infesting tilled and overgrazed land. So far no biological control agent has effectively managed the spread of C. arvense. Synthetic biology gives us a new approach to this problem. Any source of genetic code is now a potential source of information for the manufacture of a target specific bacteria. Erwinia tracheiphila is a pathogenic microbe known to cause bacterial wilt in cucurbits. It is vectored into the xylem of C. arvense by a non-specific host, the striped cucumber beetle (Acalymma vittatum). The specific gene that encodes for bacterial wilt could be identified and sequenced. If Canada thistle is susceptible to bacterial wilt, this may provide a means to create cheap and simple controls, eliminating non-target effects that plague other biological control methods. This study is an investigation into the possibility of E. tracheiphila as a source of genetic material for use as an engineered biological control agent against C. arvense. Two approaches were used to test the hypothesis that E. tracheiphila causes bacterial wilt in C. arvense. 1) Using PCR and DNA sequencing, we tested for the presence of E. tracheiphila by culturing bacteria from wilted samples of C. arvense. We anticipate verification of E. tracheiphila within these samples. 2) Inoculation of C. arvense with E. tracheiphila (ATCC# 33245) with observation of wilting symptoms followed by reisolation of the pathogen from wilted plants. Successful verification of this causal relationship could lead to an efficient biological control, alleviating the need for energy intensive and unsustainable methods of mechanical and chemical control. Stevens, Bo Faculty mentor: Ophelia Wang, College of Engineering, Forestry and Natural Sciences (CEFNS) Measuring Habitat Loss in Southwestern Nicaragua As of 4-19-13 UG Symposium Presentation Abstracts Nicaragua contains the world’s largest remaining tropical dry forests despite losing half its forest cover since the 1950’s. Habitat loss and fragmentation of these forests have devastating effects on species diversity and habitat connectivity. Characterizing land use and land cover changes for broad conservation planning necessitates the use of remotely sensed satellite imagery. Classification of land cover is being developed using the red, green, and near-infrared spectral bands, the Normalized Differential Vegetation Index from SPOT imagery, in addition to terrain variables, aerial photography, and ground truthing data. The resulting land cover map will be used by local agencies to prioritize areas for reforestation and conservation within the province of Rivas, Nicaragua, benefiting local conservation organizations by recognizing the greatest deforestation contributors and highlighting areas that need urgent conservation effort.

It was pertinent to operationally define what was measured in the surveys, such as a person's perceived level of happiness (life-satisfaction), as well as differentiate the qualities of a person with an internal vs. an external locus of control. Our demographics were mostly female of European-American descent. All participants were conveniently chosen from Northern Arizona University. This quasi-experimental study consisted of two surveys, one measuring happiness the other locus of control. These measures have been reliable in previous studies and have been found to be consistent in this study as well. Results were expected to compliment previous findings that a person with a stronger internal locus of control will have a greater level of perceived happiness. In other words those that believe that they have an element of control over their life, goals, and fate have a higher level of happiness than those that believe their fate is pre-ordained and that they do not have this same control. Ultimately, it is anticipated that a stronger correlation will appear between happiness and internal locus of control over an external locus of control.

The purpose of this internship was to promote the concept of sustainability and the "reduce, reuse, recycle" idea in children in the community. The goal is to instill an appreciation of the environment and the choices children can make to work towards a more educated and sustainable future. The internship was part of the KARES program through the non-profit organization, Friends of Flagstaff's Future (F3). Children ages three to twelve were engaged in recycled crafts and sustainability-based activities at events where F3 was present or at specified KARES gatherings. Activities included bookmarks and bird feeders made from recycled objects. The internship included planning activities, prepping necessary materials, and developing new KARES activities that were educational and engaging. I worked with other KARES interns and F3 staff to promote and develop the program. Throughout the summer and fall of 2012, children completed KARES crafts and were able to gain a better understanding and appreciation of how their choices impacted the environment. Kids were very responsive to the crafts, and their creativity was sparked as they learned about new ways to transform old materials into a new and fun project. The KARES project was further developed and promoted in the community. Children, parents, and F3 as a whole all benefitted from the positive outcomes of the internship.

This tick-vector system was eradicated from the U.S. but remains endemic in Mexico, which exports 1-2 million cattle per year to the U.S. Acaricide resistance is rampant in Mexico, and now resistant tick infestations have been observed in southern Texas. Nearly all resistant infestations in the U.S. are associated with pyrethroid acaricides. Pyrethroid resistance in arthropods is typically due to mutations in domain II and III of the Para-sodium channel gene. However, the mechanism underlying resistance in ticks is poorly understood. We addressed this problem by screening ticks from 51 locations (N=1,343) for known single nucleotide polymorphisms (SNPs) in both domains. We identified 20 locations with resistant genotypes. Although we expected to observe the domain III SNP that is found in all known resistant Mexican populations, we only found this SNP in three locations. In contrast, the majority of resistant locations in the U.S. (19 of 20) carry a domain II SNP, which is found in Australia and South America. We also discovered an additional domain II SNP in four tick collections that is associated with extreme levels of resistance in other insects. This SNP has never been described previously in R. microplus and suggests that either resistant ticks were transported into the U.S. (from Mexico or another country), or that convergent evolution has recently occurred in U.S. tick infestations. This is the first description of domain II Para-sodium channel resistance mechanisms in the U.S. Stratton, Todd Faculty mentor: Anne Scott, Honors Program Anti-Aging Effects of Aerobic Exercise Honors Symposium Proposal: Anti-aging Effects of Aerobic Exercise Aerobic exercise has several benefits to people not only in the short term, but along the life span as well. However, while most people know that aerobic exercise is healthy, most people do not know exactly why. I propose to present my academic essay of the subject, entitled “Antiaging Effects of Aerobic Exercise”. I will discuss the effects of aging with a sedentary lifestyle, look at the benefits of different amounts of aerobic exercise, examine how much aerobic exercise is too much, and point out ways to counter the negative effects of too much aerobic exercise. Stratton, Todd As of 4-19-13 UG Symposium Presentation Abstracts Faculty mentor: Wolf Gumerman, Anne Scott, Honors Program How to Start Exercising: Nutritional Differences between Non-athletes and Athletes The components of optimal nutrition between athletes and non-athletes differ because of the biological changes and requirements of the body of an athlete. A person can get by on almost any diet and still be alive, but it is not necessarily optimal. We know that there are certain requirements in a diet to keep a person healthy, but these requirements are not universal. Compared to non-athletes, athletes require additional nutrients in order to optimize health than a person who does not exercise because of the additional strain on their bodies. In this paper, I address differences in nutrition requirements between non-athletes and athletes. Sun, Jingran Rebecca K. Beresic-Perrins and Stephen M. Shuster Faculty mentor: Rebecca K. Beresic-Perrins, College of Engineering, Forestry and Natural Sciences (CEFNS) Cross-Fostering in a Leech Species, Helobdella stagnalis The tendency of Helobdella stagnalis, a leech species that provides parental care, cross-fostering adopted offspring is poorly understood. Cross-fostering in a closely related species, Helobdella blinnii has been documented. We hypothesize H. stagnalis will demonstrate the same crossfostering behaviors as H. blinnii. We set up family groups with four different treatments; Treatment 1, a parent and its own offspring as a control; Treatment 2, a parent with half own offspring and half non-own offspring; Treatment 3, a parent with non-own offspring; and Treatment 4, a non-brooding adult with non-own offspring. We found in the leech H. stagnalis does cross-foster too. We will use this information for future studies on maternal effects. Sutton, Tanya Stephanie E. Wolff, Caren C. Helbing, Nik Veldhoen, Catherine R. Propper Faculty mentor: Catherine R. Propper, College of Engineering, Forestry and Natural Sciences (CEFNS) Thyroid hormone induces dose dependent up regulation of two genes demonstrated to be sensitive to endocrine disruption during amphibian metamorphosis Thyroid hormones (THs) are critical to developmental pathways and essential in the normal function of the cardiovascular, central nervous, digestive, and reproductive systems. In amphibian metamorphosis, THs are vital in reorganization. Previous results from our lab using microarrays found that expression of two genes in particular, fibroblast activation protein alpha (FAPalpha) and corticotropin releasing hormone binding protein (CRHBP), were highly THresponsive and were disrupted by exposure to environmental contaminants. In order to further evaluate these genes as TH sensitive, we exposed <i>Xenopus laevis</i>, a common amphibian model, to 0, 0.1, 1.0, 10 and 50nM of triiodothyronine (T3) for 48 and 72 hours. We then performed real time PCR relative quantification to measure shifts in transcript levels in the intestine. The transcript levels were then compared to morphometric shifts. FAPalpha and As of 4-19-13 UG Symposium Presentation Abstracts CRHBP transcript levels were upregulated as early as 48 hours down to a concentration at 10nM and 50nM T3 exposure. By 72 hours post-exposure, FAPalpha expression was upregulated in a dose-dependent manner and was sensitive to 1 nM T3 exposure, while CRHBP also showed dose responsiveness, the lowest effective dose being 10 nM. These results indicate that FAPalpha and CRHBP are potential gene expression markers for thyroid sensitivity. CRHBP has been shown to be an important modulator of amphibian metamorphic timing, and FAPalpha expression is linked to several human cancers. As expression of these genes is clearly under TH control during development, it is important to gain a better understanding of the functional role they play in tissue organization. Tabor, Kylie Matthew Beyak, Chelsea Glantz, and Ginger Haviland Faculty mentor: Nora Dunbar, College of Social and Behavioral Sciences (SBS) What Predicts the "Freshman Fifteen"? The "freshman fifteen" is a common expression used in the United States to refer to an amount of weight that is often gained during your freshman year of college. There has been plenty of research done to support that weight is gained during your freshman year, but the predictors of this weight gain are still unclear. The purpose of this study was to link specific variables to the "freshman fifteen" or any weight accumulated in the freshman year of college. More specifically, this study was used to determine the correlation between the "freshman fifteen" and these three criteria (academic stress, nutrition, and physical activity). Data was collected in a survey format using three different questionnaires given to second semester freshman attending Northern Arizona University. The questionnaires focused on levels of academic stress, servings of food groups per day, and amount of physical activity in a week. These scores were analyzed in relation to whether or not the participant gained weight their first semester of their freshman year. All three predictors are expected freshman weight gain. Moreover, academic stress is predicted to be the least significant criterion while nutrition and physical activity are thought to be the most significant criteria related to freshman weight gain. These results should support other research that confirms there is freshman weight gain and begin to explain specific predictors for this weight gain. Taggart, Devon Alicia Miller, Nicolas Walker, Daniel Iribe, Ethan Gunzel Faculty mentor: Geeta Chowdhry, College of Social and Behavioral Sciences (SBS) The Evolution of U.S.-Pakistan Relations Pakistan has held a contentious position in U.S. foreign relations since its declared independence in 1947. Established as a secular governed Muslim state, Pakistan's politics have warred between these two ideals for decades; from military coups to foreign interference, the line between religion and politics in Pakistan is constantly blurred. With the onset of hostilities in Afghanistan during the Cold War, Pakistan's intelligence agency, the ISI, played a major role as a proxy between the U.S. and its Afghan allies against the Soviet invasion. Again with the terrorist attacks on September 11, 2001, Pakistan became an uneasy ally with the U.S. in its As of 4-19-13 UG Symposium Presentation Abstracts struggle in Afghanistan. During this time, unmanned aerial drone strikes along the AfghanistanPakistan border and deep into Pakistani territory tested the strength of the U.S.-Pakistan Alliance. These different contentions, from the United State's direct involvement in influencing the government of Pakistan to repeated drone strikes into Pakistani territory, serve as a map illustrating the history of the tenuous relationship between these two states and projects a startling view of the future of U.S.-Pakistan relations should the patterns of the past continue. Tallant, Tiana Drew Felton, Lisa Desimone, Graham Black, Dr. Suzanne Daiss Faculty mentor: Suzanne Daiss, College of Social and Behavioral Sciences (SBS) Compassionate Weight Management Groups Weight management is an issue of paramount importance as more and more American adults continue to become overweight and obese. The "Small Changes" approach encourages individuals to make small lifestyle changes that can be maintained over time as opposed to promoting radical behavior changes that can lead to immediate weight loss but eventual weight regain. Research is also beginning to explore how incorporating different types of body movement techniques (e.g, yoga, pilates, or simple walking) can contribute to weight loss. In addition, a shift toward more compassionate approaches to weight management (including body movement techniques) could be beneficial. This research suggests that incorporating body movement techniques into a small change weight loss paradigm could contribute to developing a more compassionate approach to weight management. Further research exploring how compassionate body movement interventions contribute to weight loss is needed.

My tasks as the Outreach and Craft Consultant Intern during the Fall 2012 semester were to observe how the employees communicated with each other and the Flagstaff community, and to organize, plan, and execute a As of 4-19-13 UG Symposium Presentation Abstracts program that utilized recycled crafts. After observing how Willow Bend communicated their values at events, programs, and meetings, I was able to successfully design and execute a program that created a sense of community with Flagstaff residents and Willow Bend. By bringing families from the Flagstaff community together to create gifts made out of reused and recycled materials, I was able to experience and understand how people view and communicate with non-profit organizations about their intended values. Based on my experience, I would recommend that Willow Bend seek to compile a detailed list of duties that would mutually benefit both the interns and the organization so that both parties feel like their time is being sufficiently utilized. I would also recommend that Willow Bend employees have a monthly meeting to communicate with each other about their individual values compared to the organization's as whole so as to continuously evaluate how they are communicating about the organization's values to the Flagstaff community.

These corridors appear in urban areas that may otherwise obstruct successful migration from one habitat to another. The Flagstaff area has over twenty wildlife corridors that are meant to assist local focal species to survive while migrating from one wild land block to another. The Flagstaff corridors focus on a wide array of species including pronghorn, mountain lion, mule deer, black bear, elk etc. This promotion of landscape and habitat connectivity allows successful migration of animals between habitats, which reduce the risk of isolating populations. Furthermore the wildlife corridors prevent the risk of human motorist accidents with wildlife. The benefits of wildlife corridors in urban development sites include understanding how the interactions between all forms of life affect the continued successful growth of the environment as a whole. Taking a systems approach towards incorporating wildlife corridors into urban development plans allows residents to see and experience the natural environment in their daily life and develop a connection to the continuation of development as a consideration of all aspects of life. An interdisciplinary approach towards wildlife corridor development will allow all perspectives and values to be involved in the discussion of future projects. Incorporating new structures and integrating habitat loss effects into zoning and land use regulations will help decrease the negative effect of human and wildlife interactions.

Thompson, Chad Tate Reed, Cassie Field Faculty mentor: Joe Barbour, John Houser, College of Social and Behavioral Sciences (SBS) Personality Type and Sports Choice This study focuses on the relationship between the personality types of athletes and the choice of sport they have made. The teams being studied are tennis, hockey, track, and soccer. Through the use of the Big 5 Personality Test, participants of NAU sports teams will take a personality inventory to be examined. Although the Big 5 breaks personality down into individual traits (Extroversion, Agreeableness, Openness, Neuroticism, and Conscientiousness), it will be the composite variables that are actually tested. A series of ANOVA analyses will be run on each category to determine the relationship between the sport choice and personality type, and how strong the correlation actually is. Based off of these results, the correlations will be compared to the F values of each category to see how strong the correlations are. The findings will be able to contribute to areas of psychology such as sports psychology, and how each sports team may require a different approach to helping athletes psychologically, and to be able to cater to the needs of those athletes better.

DOE is a governmental department whose mission is to advance energy technology and promote related innovation in the United States. The purpose of this internship was to gain experience for a career in the federal government. The main focus of this internship was to assist staff members of EERE’s Office of Weatherization and Intergovernmental Programs (OWIP) with the Better Buildings Challenge (BBC). As a program analyst intern, my primary duties included, but not were not limited to, the following: 1] assisting OWIP staff with various BBC initiatives; 2] developing and managing a systematic database containing comprehensive data of BBC resources; 3] aiding in a proposal to implement a water & wastewater conservation category into the BBC. My objectives were to 1] to gain an understanding of the various aspects involved in running a successful federal program; 2] to enhance my skills in organization, communication, As of 4-19-13 UG Symposium Presentation Abstracts and computer software; 3] to learn the processes involved in writing effective proposals. In cessation of my internship as a program analyst intern, I successfully completed each of my objectives and strengthened my skills in financial analysis, research, writing, organization and communication. As this internship required a comprehensive understanding of computer software and fundamental business knowledge, my recommendations are for the Environmental Studies program at Northern Arizona University to implement required coursework in the fields of business and computer sciences. Thurston, Nicole Faculty mentor: Rebecca Javorsky, College of Arts and Letters (CAL) Teaching Ancient Languages in Schools A "dead" language is one that is no longer spoken as a native tongue. Languages naturally mutate and come into or fall out of favor through the centuries as different groups come to power and cultural trends come and go. However, though these ancient languages are no longer learned as native languages, they still exist in documents written when they were native languages, and can therefore be studied and learned as foreign languages. Two of the most common ancient languages studied today are Latin and Ancient Greek, but their study is rarely mandatory for students; rather, they are offered as optional language electives. At a time when the United States is seeking to empower its youth with the knowledge to succeed in an increasingly global and competitive world, the study of these dead languages should be given priority. Studying ancient languages such as Classical Latin and Greek is beneficial for students in all areas of their education, and my presentation will focus on why this study should be promoted and encouraged at all levels from middle school to college.

Computer modeling showed that the GX 100 exhibited the greatest fuel efficiency at the engine output levels that we planned on operating at during the competition. The drivetrain is a chain and sprocket system. A sprocket based system was selected because of it exhibited very little As of 4-19-13 UG Symposium Presentation Abstracts torque loss during transmission, was light weight and was versatile in possible gear ratios. The wide variety of gear ratios was of particular importance. The ability to optimize the transmission of torque and rpm for fuel efficiency was crucial in our designs.

Our designs for the brakes and safety features were loosely based on those of the previous vehicle entered in the competition by NAU. Tucker, Megan Hannah Naumann, Barbara Kozlowski, Rachel Rohrer Faculty mentor: John Houser, College of Social and Behavioral Sciences (SBS) The Effect of Communication Methods on Friendship Quality Previous research on friendship generally focuses on online communication and its effects on friendship. This narrow focus results in a gap in the research because researchers neglect the amount of time spent using different types of media to communicate versus to face-to-face interactions. The purpose of this study is to see if the type of communication (online social networks, texting, phone calls, Skype, and face to face) and amount of usage affect friendship quality. A survey was given out to a sample of 125 undergraduate students at a small rural university in the Southwest region during class time. The study found that there is a negative correlation between high media usage and low friendship satisfaction. The research indicates that the more types of communication technology used increased reported quality of friendship, while the use of one method of communication stagnates friendship satisfaction. In other words, it is easier to preserve friendships when using multiple media sources such as calling, texting, and Facebook simultaneously. The research has also shown that distance between friends encourages media usage. Gender affects friendship quality and preference of type of communication. Overall, the data shows that communicative technologies negatively affect friendship bonds. Turner, Elyce Cassie Rodriguez, Hunter Mudgett Faculty mentor: Matthew Anderson, College of Social and Behavioral Sciences (SBS) Self-Esteem and Social Networking In this study we are measuring self-esteem and its correlation with social networking. Students from Northern Arizona University were selected using convenience sampling. The participants then completed a Rosenberg Self-Esteem Scale (1965) and a brief questionnaire pertaining to their social networking use, which included such sites as Facebook, Twitter, and Tumblr. The questions that were included on the questionnaire ask about their time spent on the social networking sites and how frequently they use them per day. The results will explain whether or not there is a correlation between social networking and an individual’s self-esteem. Tyler, Ariana Faculty mentor: George Gumerman, Honors Program As of 4-19-13 UG Symposium Presentation Abstracts How Taboo is too Taboo? My presentation is based on food taboos in the United States, specifically the taboos against eating animals considered "pets." Many American people view their pets as "part of the family," and because of this mentality, eating animals such as, but not limited to, dogs, cats, and horses is frowned upon and considered taboo. There are a few major reasons why these taboos continue to exist, among those are availability and lack of need. These two reasons will be broken down and examined to determine their influence in American taboos, along with a few other reasons that may be contributors.

However, many off-grid systems experience problems because non-linear electrical devices create harmonic distortion in the system’s power lines. A system with significant harmonics causes increased temperatures in electronics thereby shortening their lifespan while also damaging the power system itself. The purpose of this project was to create and test a shunt active power filter that reduced harmonic distortion in off-grid energy systems. The filter designed and created by the team reduces harmonics injected by a wide array of nonlinear electrical devices commonly found in off-grid energy systems thus increasing their efficiency and longevity.

Unruh, David Faculty mentor: Nancy Riggs, College of Engineering, Forestry and Natural Sciences (CEFNS) Lava dome viscosity and associated structures In the San Francisco Volcanic Field of northern Arizona, lava domes have varying effects on the rocks they must intrude to reach the surface. Some domes sit on the surface with no visible deformation of the rocks above, while others deform several layers of rocks above to reach the surface. This study seeks to correlate viscosity of the intruding lavas with the deformation the domes create. The domes studied are the Wright Hill Rhyolite, the White Horse Hills Rhyolite, and the Mt. Elden Dacite. For this study, field mapping was used to determine deformation of sediments by dome lavas. Viscosity was calculated using geochemical data from a 1987 survey of the San Francisco Volcanic Field by Wolfe et al. The equation used to determine viscosity was a modified form of the Arrhenius model (Genova et al 2013), which relates viscosity to temperature. The composition of plagioclase phenocrysts was calculated to determine at what temperature the lava cooled. Viscosity was found to be related to dome deformation, but other factors also have a large effect. A factor that is important to deformation is the storage depth of the magma before the lava is extruded. If the magma is stored higher up in the crust before being extruded, it is more likely to deform rocks above. Due to the limited time and budget allotted for this study, it is difficult to determine what the most important factor in deformation of rocks by lava domes.

By comparing the current Kingman Regional Medical Center (KRMC) policy with that of current evidence, our research indicates that no difference in VAP risk is noted between the studies that compared both mouth care techniques and therefore, the current KRMC policy should continue to remain the same. Van Winkle, Helena Faculty mentor: Scott Anderson, College of Engineering, Forestry and Natural Sciences (CEFNS) Southeast Alaska; A Learning Experience As of 4-19-13 UG Symposium Presentation Abstracts Preparing for a career in the Environmental Sciences, I spent five weeks traversing the wilderness of Southeast Alaska by kayak. Daily life in this wilderness included tasks such as setting up camp, using navigational materials to plot a safe course through tidal shifts, identifying and differentiating poisonous plants from harmless plants and safely scouting out an area for hazards such as bears. The skills learned in this educational opportunity will be beneficial in the future in many possible areas of life from outdoor field research to teaching children basic survival techniques. By being totally immersed in the wilderness of Southeast Alaska I was able to extensively learn the interactions between organisms, habitats, and the impact and influence of human policies and interactions. The knowledge gained during this time will continue to influence my future actions and has already changed the manner in which I interact with my local environment. Vargas, Brianda Vargas, Brianda Isabel;Brown, Riann Gabrielle Renee; Descheny,Renica Ann; Duplessis, Caley Eileen; Whittet, Kellie Kristina Faculty mentor: Mathew Anderson, College of Social and Behavioral Sciences (SBS) Are You Satisfied? A Study Looking at Divorce and Relationship Fulfillment Family structure has a great influence on adolescents’ own personal relationships. Divorce is becoming more common in American society, which means that more adolescents are forced to deal with the long-lasting social and emotional effects. Previous research has mainly focused on the negative effects of divorce on children; therefore, the purpose of this study is to evaluate the effects of family structure on college students in romantic relationships. Data was collected from more than 100 Northern Arizona University Psychology 302W students through a survey measuring romantic relationship satisfaction. We hypothesize that students from non-divorced families will show significantly higher levels of satisfaction within their romantic relationships, compared to students coming from a divorced family. We hope to conclude that the negative experience of divorce can impact young adults’ future and personal romantic relationships. Overall, the study will reveal the importance of the roles that parents play within their children’s social interactions throughout their lives. Vavra, Grant Faculty mentor: Kerri Quinn, Honors Program Walls This piece of fiction focuses on a young man forcibly admitted to a mental facility.

Veglia, Anthony Faculty mentor: George Gumerman, Honors Program Location, Location... Geographic Luck Determines the Success of a Culture As of 4-19-13 UG Symposium Presentation Abstracts There is an immense difference in the success of a culture when one is a Papuan tribe while the other leads the Roman army. These differences took many years to form and may have a number of variables but one constant in all cultures is food. The available food for a culture is what decides their efficiency and future success. Venezia, Allison Nick Jurik, Timothy Tormey, Joseph Cavaretta, John Hills, Peter Journell Faculty mentor: Srinivas Kosaraju, College of Engineering, Forestry and Natural Sciences (CEFNS) Small-Scale Solar Irradiance Measuring Device The Institute for Sustainable Energy Solutions (ISES) at NAU is working with WindLogics, Inc. to evaluate the reliability of the solar resource to determine the viability of a large scale energy generation project at the COBar Ranch, near Flagstaff, AZ. The current evaluation method uses a square mile monitoring station with many data collection devices to determine the reliability of the irradiance. The small-scale solar irradiance project implements a device which refines the existing system, and accurately models the irregularities of solar irradiance. The goal of the project is to streamline data collection while minimizing cost, land area usage, and system assembly time. This is achieved by implementing five pyranometers, arranged in a cross pattern located 40 feet apart, connected to one centrally located Data Logger. To reduce the overall set up time for the site, and to create an easier experience for the client, the sensors are mounted to tripods secured to the ground. A statistical analysis of the current site’s irradiance data determined average cloud event speeds as well as the corresponding direction vectors. Using this information as well as the chosen sensor spacing, the data sampling rate was set at 4Hz to ensure the system accurately models the variance in the solar product. Vernon, Daniel Faculty mentor: Scott Anderson, College of Engineering, Forestry and Natural Sciences (CEFNS) The Challenges of communicating climate change issues to the public In communicating climate change issues to the public, one must realize that this term has been used and misused to describe a multitude of topics that the greatest challenge will be in finding common ground with the audience on which to begin positive discussion. Begin any discussion of climate change with a basic definition so that the audience understands the correct meaning. With this definition you can begin to build your case on a common foundation. The type of audience you are addressing will determine the language you will use: scientists, politicians, community leaders, students or general public. Know your audience and make your communication issues personal and easily understood. There are seven key concepts of climate change that need to be communicated so that the audience knows and understands that this is not just some made-up theory or political agenda. When the concepts are described and the consequences understood, then solutions can be presented. Involving the public in determining possible solutions will build the team spirit that will be taken home by each individual to create As of 4-19-13 UG Symposium Presentation Abstracts positive changes in their home, work place, community, and schools. The main challenge of communicating climate change issues is getting the public to realize that it is real, and that they have a choice to work towards solutions and determine their own future. In determining their own positive solutions, they will contribute to a better environment and make a difference in our world. Vernon, Daniel Faculty mentor: Rod Parnell, College of Engineering, Forestry and Natural Sciences (CEFNS) Soil Science in Northern Arizona The opportunity to intern as a volunteer Earth Team Soil Scientist with the Natural Resource Conservation Service (NRCS) has introduced me to various types of environmental careers with actual hands-on experience in many of these fields. My goals that were set at the time of my request for internship have not only been met but have been surpassed. These accomplishments include mapping, classifying, describing, and correlating soil survey data; assisting in the field and observing ecological sites and their state in transition; gaining knowledge of soils and plants as well as collecting and identification of types and species; introduction to specific soil survey procedures, field-testing, and laboratory activities; discussion on required documentation and publication requirements; range-land management; measuring snow depth for data studies on absorption, evaporation, and spring runoff; observation studies of the almost extinct condor; and working as a team member in various situations. Northern Arizona, especially the Flagstaff area, was the District area that I worked in, extending over to the Navajo and Hopi Tribal Lands as well. This vast area allowed me to observe the diverse ecological environments ecosystems. I was also introduced to ancient archeological history and settlement sites. Working with the professionals at NRCS gave me the opportunity to learn from their experience and to actually observe the process of a government agency assisting and guiding private individuals in a joint effort to protect, conserve and restore the various ecosystems in Northern Arizona. With over 300 hours of internship, I have accomplished my goals. Villalobos, Matt Faculty mentor: Dean Smith, Franke College of Business (FCB) Bureau of Reclamation and Water in the West Exploring the future of water reclamation in the southwest and analyzing the current Reclamation Bureau's ability to meet Municipal needs Virgo, Richard Faculty mentor: Crystal Peebles, College of Arts and Letters (CAL) The Influence of Pitch Proximity on the Aesthetic Judgment of Unfamiliar Melodies This study investigates a listener’s melodic expectations and the perception of closure in three melodies that represent different musical styles. Prior research in the realm of tonal harmony As of 4-19-13 UG Symposium Presentation Abstracts indicates that listeners are predisposed to expect a stepwise progression at the end of melodies to conclude musical thoughts. This study will determine if listeners prefer stepwise progressions regardless of musical style. Within the common-practice style, tonal syntax also may influence the participant’s perception of closure. Other research suggests that each note of a scale conveys a varying degree of “restfulness” or “forward motion.” Instead of relying on stepwise motion, participants may interpret endings as sounding more closed if they conclude with a scale-degree that implies “restfulness” in accordance with common-practice patterns. Within this study, participants actively listened to examples of music from the Baroque, Romantic, and Modern eras. Using a probe-tone methodology, the last note of each example was translated up and down six semitones from the original pitch. Participants proceeded to rate each of the thirteen versions of each example twice: first determining the strength of the completion, and then indicating an aesthetic judgment regarding how satisfying the ending sounded. This research supports the perceptual validity of music theories and provides insight about cognitive mechanisms in musical expectation and judgment. Wabli, Khalid Kristen Milligan, Luke Contreras Faculty mentor: Christopher Mann, College of Engineering, Forestry and Natural Sciences (CEFNS) REAL TIME IMAGING OF BIOLOGICAL STRUCTURES USING DIGITAL HOLOGRAPHY AND TOMOGRAPHY Digital Holography and Tomography captures high resolution images of biological cells in real time. This technique allows the monitoring of changes in intracellular features along with surface topography. The motivation of this research is to provide the biomedical field with a noninvasive approach for obtaining a greater breadth of information on cellular morphology and structure. Furthermore observations of biological morphology are able to be conducted with great speed using a self-calibrating/self-adjusting microscopic system as well as automated analysis of acquired data. Biological movements in transparent objects that yield refractive index changes or variations of the shape are very pertinent to biological and clinical research. Biological events in transparent objects that produce refractive index changes or variations of the shape are a focal point for biological and clinical research. It is often the case that bright field imaging is used to observe these events; however they are limited in their capabilities. First, they have a small depth of focus at high magnifications; secondly they have inadequate ability to effectively observe transparent samples such as living biological cells which exhibit very little intensity contrast, and thirdly but most importantly they cannot capture the phase information. The phase information is very important as it provides structural or refractive index information about the sample. By using both digital holography and tomography, we now have access to a refractive index via the phase information capture, with single nanometer precision, allowing for detailed data retrieval. Wachs, Kurtis Harper Alfred, Daniel Baronsky, Nicholas Rowe, McKenzie Schmidt As of 4-19-13 UG Symposium Presentation Abstracts Faculty mentor: Sheryl Howard, College of Engineering, Forestry and Natural Sciences (CEFNS) Radio Inter-Module Communication Testing Cobham Aerospace is designing a radio to be used in various aircraft, which is split into different modules that will communicate with each other. They want to avoid the possibility that important data may be corrupted due to noise and interference. Our team developed a test system to analyze communications between the radio modules when noise is introduced. This was accomplished by writing code for a field programmable gate array board and developed a graphical user interface (GUI) to display the results on a computer. Using the Verilog programming language, we simulated the communication link between different radio modules and analyzed it when noise is injected into the system. The GUI allows the user to monitor the communication link and test the communication reliability with different parameters. With the software we created, Cobham will be able to test how their radios will be affected by noise in their application.

Walsh, Jessica Faculty mentor: Melissa Santana, Carl Clark, College of Arts and Letters (CAL) Creative Healing at Any Age: Designing an Arts Therapy Center for Older Adults Art therapy is a form of holistic therapy that which focuses on a connection between the mind and body and uses healing approaches that do not involve medication. These approaches include art forms such as painting, sculpture, drawing, and even performance art such as dancing. Art therapy can be beneficial to anyone, regardless of age and reason for seeking therapy. Art therapy is a blend of the therapeutic, psychological, and natural creative processes. When a patient expresses himself or herself through a medium of art such as drawing or painting, it allows them to communicate thoughts and feelings that they cannot expresses verbally, which has proven to be very beneficial to the older adult and elderly population. As we age, we are susceptible to a number of health conditions that can change our perceptions and our way of life. Some of these health conditions include visual impairment, arthritis, osteoporosis, muscular degeneration, Parkinson’s disease, and Alzheimer’s disease. Art therapy can effectively aid older adults in coping with and accepting these life changes by stimulating memory/brain function, providing a sense of meaning and responsibility, and providing a distraction from physical pain. Many studies have shown that older adults who participate in art As of 4-19-13 UG Symposium Presentation Abstracts therapy programs experience improved physical and mental states and thoroughly enjoy experiencing in the creative process. The goal of this project is to design an arts therapy center in Flagstaff, Arizona, for older adults that comfortable and functional for both the patients and the staff. The concept for the center is to create an open and simple space that is welcoming and easy to navigate for the patients, while incorporating a clean and contemporary aesthetic, with touches of natural and organic elements. Walters, Julya Faculty mentor: Nancy Barron, College of Arts and Letters (CAL) Rhetoric of Food and Travel Writing Warden, Laura Dr. Robert Till Faculty mentor: Robert Till, College of Social and Behavioral Sciences (SBS) Influence of Mind-Wandering and Reading Comprehension on Inference Making Mind-wandering is associated with poor performance on reading comprehension tasks (Mooneyham & Schooler, 2013. We reasoned that lapses of attention might be harmful to the literal understanding of stories and to thematic inferences that can be drawn from them. We asked NAU students to read a disturbing essay about chemicals before testing their comprehension of experimental stories. They then wrote a response to how chemicals affect them. Experimental stories were then presented on a computer screen, one phrase at a time. We also included yes/no questions referring to the chemical essay to revive the disturbing aspects of that topic. We asked for yes/no self-reports of mind-wandering at four points. Each story was interrupted with lexical decision tasks in which a target appeared (a word or non-word) and the reader made a yes/no decision. Our 48 participants were split into high vs. low groups on two factors: literal comprehension and mind-wandering. We looked for inferences by comparing lexical decision latencies for target words that named a probable inference to latencies for targets that did not name an inference from the story. Some targets appeared at timely locations; others were delayed and appeared after trivial story details were given. Results showed that readers low in mind-wandering drew thematic inferences, whether the inference targets appeared at timely or delayed points. Those readers high in mind-wandering, on the other hand, rarely drew inferences. Only those high in literal story understanding did so and only at the optimal, timely point in the stories.

Many ILs contain both hydrophilic and hydrophobic properties, and this affords them many unique characteristics as a solvent when compared to molecules that are strictly hydrophobic (such as oil, or many hydrocarbon solvents) or strictly hydrophilic (such as water or ethanol). For example, ILs have been shown to be able to dissolve materials that could not be dissolved by water or an organic solvent—i.e., wood, sawdust, and wool. In this project, we have tested the effects of 1-butyl-1-methylpyrrolidinium bistriflimide (BMP-NTF2), an IL, on established bacterial biofilms of Staphylococcus aureus and Pseudomonas aeruginosa in conjunction with known antibiotics. Many infections, including those of the skin or of surfaces, are due to bacterial biofilms, and biofilms are known to be much more resilient towards antibiotics than cells in solution. Bacteria within the biofilm are protected by a thick polysaccharide layer produced by the cells, which contributes to their resistance to antibiotics. Our experiments tested if the IL could increase the potency of antibiotic treatment against biofilms or improve the shelf life of an antibiotic (gentamicin). Wash, Ethan Faculty mentor: William Culbertson, College of Health and Human Services (CHHS) Phonological Awareness in Spanish ESL Students Locality, culture and socioeconomic status play a major role in language acquisition. Native speakers of a given language learn socially acceptable productions of the native tongue, but they often have difficulty adopting the native phonology of a different language. Second-language acquisition comes with a myriad of challenges that must be overcome if one hopes to achieve fluency and comprehension in their second language. This study will assess specifically the phonological awareness of Spanish ESL (English as a second language) learners in hopes of finding patterns in phonological insufficiencies. At the same time, it will seek out any possible correlations between such insufficiencies and the subject’s prior academic background. This project will specifically address the question: “are there certain patterns of phonological deficiencies among beginning Spanish ESL learners based upon their educational backgrounds?” Findings from this study could potentially play a contributing role in English phonological pedagogy. As of 4-19-13 UG Symposium Presentation Abstracts Watson, Rachel Shelby Wade and Natalie Holmes Faculty mentor: Brant Short, College of Social and Behavioral Sciences (SBS) The Myth of the American Dream Perpetuating Poverty in the Media Negative stereotypes have become embedded in American society about the poor. Societal conceptions about the poor have shaped the way people react to the poor, the policies put in place to deal with poverty, and the perceptions that people in poverty hold about themselves. These stereotypes may be fueled by the myth of the American Dream. This myth suggests that material success can be achieved through hard work and diligence within our egalitarian community. Therefore, stereotypes often represent the poor as lazy or unwilling to work for a better life. In reality, research today suggests that this cycle of poverty is challenging to escape. Even hard working individuals often struggle to succeed due to class constrictions. The American Dream that there is opportunity for upward mobility has been used to define our nation, yet it tends to misrepresent the reality of poverty today. The media plays a major role in shaping our society and defining how we view the poor. This study uses a mythic analysis to examine media stories that perpetuate the myth of the American Dream. We focus on media’s attention to success stories that involve people’s ability to move from rags to riches. Part of solving current the problem of poverty today involves rewriting this idea of the American Dream to more accurately address the issue of poverty. Rather than fueling stereotypes that keep certain people in poverty, the American Dream’s emphasis on equality could be used in a more positive way to counter the class constrictions and disadvantages present within our system.

Heavy infestations of these insects can negatively impact plant communities and therefor may be detrimental to local fauna. In Saipan, we identified the galling insect infesting native coral trees (Erythrina variegata var. orientalis) and tested the potential effect this insect has on bird visitations. To identify the insect, we reared insects from five leaves of five haphazardly selected Erythrina trees and taxonomically identified them. To quantify differences in gall abundance amongst trees, we counted gall abundance on 32 trees. To evaluate the potential effect galls have on birds, we quantified bird visitations to trees with high and low gall abundances. Insects reared from leaf samples fit the description of the introduced Erythrina gall wasp (Quadristichus erythrinae). A Wilcoxon analysis showed significant differences in gall abundances amongst trees (n = 32, χ2 = 296.87, p < 0.001). A Mann-Whitney U test showed a significant increase (n = 14, χ2 = 18.23, p < 0.001) in bird visitations to trees with high gall abundances. The endemic bridled white-eye, a species of conservation concern, comprised around 90% of all bird visitations. These data suggest that As of 4-19-13 UG Symposium Presentation Abstracts the Erythrina gall wasp, though considered a pest in other tropical communities, may be a source of food for bridled white-eyes and other birds in Saipan. Watts, Sara Kelli Rider, Elise Cheever, Jonathan Brusnahan, Naser Aljaberi Faculty mentor: Joshua Hewes, College of Engineering, Forestry and Natural Sciences (CEFNS) ASCE Concrete Canoe: Night Fury The purpose of the American Society of Civil Engineers’ (ASCE) Concrete Canoe Competition is to design, build, and race a unique and innovative canoe that satisfies the requirements set forth by the National Concrete Canoe Competition (NCCC). Participating in the concrete canoe competition allows students to practice skills they have gained in engineering classes. The regional and national competitions are held to increase the importance of ASCE membership in civil engineering profession and build awareness of concrete as a major construction material. Tasks of the project included unique concrete design, structural analysis, hull design and post tensioning. This year's team built Night Fury, meant to improve greatly on previous NAU concrete canoes. Webber, Michelle Faculty mentor: Anne Scott, Honors Program The Perverse: Sociopathic Tendencies of the Bond Villain Ian Fleming often emphasizes the sadistic and the sociopathic as means to characterize Bond villains. Their lack of human compassion presents a fascinating dichotomy of depicting good versus evil, minimizing Bond's flaws in comparison and, in essence, championing Bond as the clear hero. Weber, Alana Faculty mentor: George Gumerman, Honors Program The Environmental Impact of Food Waste in America As Americans, we have a mentality that we can we buy any type of food we want and if we do not like it, or if we do not want the rest we can then just throw it out. Our fast-pace culture has given us the opportunity to not care about where our food goes once it leaves our kitchen. Yet this mentality has created a detrimental impact on the environment. In my research poster, I will talk about how this American way of thinking has come about, the environmental concerns that have come from wasting American food, and how we as Americans can change this mentality.

Our poster examines the political creation of Chicana women’s identity, considering the roles that bodypolitics, representation, and the economy play in the cultural formation of both individuals and groups. By creating a model of the factors involved in the external creation of Chicana identity we hope to demonstrate how dominant culture marginalizes peoples and groups, and to create a framework for future activism. Weir, Matthew Faculty mentor: Dean Smith, Franke College of Business (FCB) Energy Water Nexus This project discusses water and energy in Arizona. White, Emily Faculty mentor: Scot Raab, College of Health and Human Services (CHHS) Alternative Treatments for Patellofemoral Pain Syndrome (PFPS) Patellofemoral pain (PFPS) occurs in up to 40% of active adults and is described as anterior knee pain. This study addresses functional inequities. It’s hypothesized that ultrasound (US) treatment joined with therapeutic exercise will reduce subjects’ pain. Finding evidence based treatments (EBT) for PFPS is difficult. This study has the potential to establish EBT for PFPS. Individuals with chronic PFPS will be included. Structural abnormalities or contraindications to US will be exclusionary. Random assignment to US or sham US will occur. A pre-post pain assessment using a visual analog scale, questionnaire, and functional screening will take place. It is expected that US will decrease pain when compared to those receiving sham US. Participants will attend therapy three times weekly for six weeks avoiding any treatments outside of the study. Whitlatch, Aaron Patricia Countryman, Aaron Whitlatch, Anthony Everett-Osvog, Sindia Perez, Lynda Chaprnka, Rose Eitemiller Faculty mentor: Constance Brown, College of Arts and Letters (CAL) NAU-Yavapai Civic Forum What is community engagement and why is it important? The presence of the fairly new NAUYavapai campus within the Prescott Valley community represents an important asset. As such the students of the Community Development and Sustainability Program identified community As of 4-19-13 UG Symposium Presentation Abstracts engagement as an important way of connecting to the community. The objective of this project was to identify ways in which to engage the public on issues of community development and sustainability. Following the problem identification and needs analysis approach to program planning and evaluation, we determined that a community forum would be the most effective medium for engaging the public within the limitations of our time frame. Over a period of seven weeks a promotion campaign consisting of multiple forms of media including radio, television, newsprint and social media was implemented to generate interest in a civic forum. The forum was attended by a cross section civic leaders and community members. The forum facilitated a dialog by means of presentations and roundtable group discussions on community development and sustainability issues. The outcome of the forum allowed us to gauge the sentiment of the community's issues of importance and shared meaning as well as to establish a foundation upon which we can continue to build community awareness and connection. As the NAU-Yavapai campus grows along with the community of Prescott Valley it is important that there be an exchange of ideas and information. The organizers of the forum hope that such an ongoing dialog will foster the type of social capital needed to build a strong and sustainable community. Wiggins, Kristin Faculty mentor: Jolene Bowers, College of Engineering, Forestry and Natural Sciences (CEFNS) Evaluation of Molecular Methods of Coccidioides Detection in Clinical Specimens Laboratory methods currently used to diagnose coccidioidomycosis (Valley Fever) include serology (IgM screening) in conjunction with patient history, as well as culture with DNA probe confirmation. Methods such as these can delay diagnosis because the turn-around time is remarkably slow. Coccidioidomycosis usually presents as a pulmonary infection, a condition that can be caused by myriad bacterial, fungal, and viral agents, which further complicates proper diagnosis and can lead to improper treatment. Direct detection of pathogen RNA in a clinical specimen by real-time PCR to diagnose the cause of an infection is rapid, specific, and sensitive. This method requires only a standard RNA extraction from the clinical specimens at the BSL2 level, followed by a quick, easy PCR setup. Other detection methods require the isolation and growth of the Coccidioides, and the culture is restricted to BSL3 labs. This assay can give more clinicians access to Coccidioides detection tools because it eliminates the need for culture and BSL3 level work. RNA detection is more sensitive than DNA detection because the assay targets protein synthesis. It will be at an even higher copy in RNA than it is in the genome itself. The high copy target can still be detected at lower levels in DNA, so even this form of detection is more efficient than standard methods. This novel assay can routinely detect Coccidioides in clinical specimen RNA. More rapid and accurate diagnosis of Coccidioides infections could lead to faster and more accurate treatment of this disease that could alter patient outcomes. Wilber, Kiersten Faculty mentor: Rod Parnell, College of Engineering, Forestry and Natural Sciences (CEFNS) Nature Education in Southeast Alaska In my internship, I was focused on learning effective techniques of teaching children about science, outdoor skills, and the environment while fostering an appreciation for nature. I worked As of 4-19-13 UG Symposium Presentation Abstracts for Discovery Southeast, a nature education non-profit in Juneau, Alaska as an Assistant Naturalist. My main task was co-leading a summer day camp called Outdoor Explorers for children ages 7-12. With my co-leader, I helped create weekly themes for the camp focusing on different environmental topics. I planned outings, organized guest speakers, and designed environmental education activities that focused on each week’s theme. I implemented these programs and led campers on daily hikes to different environments in the Juneau area. Some environmental education strategies I used in the camp were: guest scientist speakers, naturethemed games, tending to a community garden, science activities, outdoor adventures, and creative exercises. I discovered the effectiveness of very hands-on, kinesthetic activities for kids, and the importance of nature awareness activities. After several weeks of striving to run a very educationally focused, pre-planned camp, I realized how vital unstructured, free playtime is to kids’ creativity, discovery, and exploration. These strategies all worked toward inspiring in campers a sense of wonder about the world around them. The Outdoor Explorers camp is a wonderful program, and I felt that by connecting these children to nature I was helping to inspire a future generation of more environmentally aware citizens. Wilcox, Morgan Faculty mentor: Adam Hoffman, Honors Program The Life You Are Given The paper is comparing the two Wes Moore’s in Wes Moore’s The Other Wes Moore. The two men grew up in the same part of town, went through childhood with common criminal actions. As Wes Moore grew up, his mother could no longer stand her son doing the wrongful things he had been getting himself into, so she sent him off to a military school for a second chance. Sadly, the Other Wes Moore’s mother did not take action in cleaning up her sons act, and he ended up getting a life sentence in jail. Some people have similar qualities, it is what they do with them that makes them who they are. These two men grew up in a place where almost everyone in their community had some sort of connection with drug dealing. If these boys were to have grown up in a different area of their state, they would not have been put in the situations that they were in. The Other Wes Moore would most likely not be in jail. Their social status did not help them in any way. Their parents were both divorced and tried their best to take care of their Moore’s, but it was the best they could do for the city they lived in. The two had too many options of being a drug dealer that it would have been hard for their mothers to keep them from it, because it was on every corner. If they had another chance with different surroundings, the boys would have had a better childhood. Wiley, Kory Faculty mentor: James Sample, College of Engineering, Forestry and Natural Sciences (CEFNS) Analysis of Shallow and Deep Water Carbonates from the Cascadia Subduction Zone Carbonate minerals that form from the precipitation of fluids provide key insight into the conditions under which they formed. Carbonates can often precipitate from fluids that migrate through faults. The accretionary wedge of the Cascadia Subduction Zone contains numerous faults, which serve as conduits for fluids to travel. The composition of fluids that travel through As of 4-19-13 UG Symposium Presentation Abstracts the wedge will change over space and time, altering the chemistry of the precipitated carbonates. The purpose of this project was to study the chemistry of deep and shallow sediments at the Cascadia Subduction Zones. Previously collected samples from drill sites 892 and 891 near the coast of Oregon were analyzed as thin sections for this study. Petrography was used to locate calcite veins and create a photo mosaic of collected thin sections. Scanning electron microscopy was used to study vein composition and vein growth textures. Elemental analysis was performed using inductively coupled mass spectrometry. Finally, x-ray diffraction was used to determine mineral composition. Differences in the composition and mineralogy of samples were compared using the collected data. Changes in the vein composition over time were determined using cross cutting relationships. This research has provided a better understanding of the conditions present during the formation of veins within the accretionary wedge of the Cascadia Subduction Zone. Wilkins, Thomas Doug Freeman, Luke Tytor Faculty mentor: Steven Jacobs, College of Engineering, Forestry and Natural Sciences (CEFNS) Project Mjolnir: Plasticity Modeling Software with MATLAB Plasticity is how a material behaves when stress is applied over time. Current models poorly predict material behavior, leading to inefficient design, less structural reliability, and increased potential for structural failure. Dr. Heidi Feigenbaum of NAU’s Mechanical Engineering Department is currently researching new models to better anticipate how materials react to stress. More accurate models could lead to lower maintenance costs, as well as improved structure designs. Dr. Feigenbaum has software that assists her in testing new models, but that code is difficult to maintain and change. While the code performs as intended, it was developed as a set of independent functions, making the program difficult to work with. Much of it is redundant, requiring changes in several locations for simple revisions. Runtimes are long, and pre and post processing are inefficient, requiring time intensive user interaction. In order to solve these problems, the previous code base was analyzed for its essential functions. Mjolnir was designed to provide the same functionality in a more convenient, efficient, and easily maintainable manner. Accomplishing this, Mjolnir creates an easy to use interface, maintains accuracy, and reduces processing time by 50%. This allows for more efficient research, possibly leading to more accurate models, and improving the quality of engineering projects. Williams, Cody McNeill, D., de Heer, D., and Coast, J.R. Faculty mentor: J. Richard Coast, College of Engineering, Forestry and Natural Sciences (CEFNS) Decrease in Metabolic Cost of Running across Trial Using a Treadmill that Unloads the Runner Purpose: This study investigated the metabolic response to running at reduced body weight in a lower body positive pressure treadmill (anti-gravity treadmill – Alter-G). We sought to examine As of 4-19-13 UG Symposium Presentation Abstracts how oxygen uptake (VO2) accommodated to repeated bouts of exercise in the reduced body weight environment, at sub-maximal intensities of running. It was hypothesized that the VO2 would decline and eventually stabilize with repeated bouts of un-weighted running in people already engaged in regular training. Such a decline would reflect accommodation as the person got more comfortable with the sensation of decreased body weight. Methods: Five trained male runners (average age 24.4 years-old) completed an incremental treadmill test in order to measure maximal aerobic capacity (VO2max) and maximal heart rate (HRmax). The subjects then completed seven identical trials on the anti-gravity treadmill at body weights of 50%, 70%, and 90% and at running speeds corresponding to 70-80% of their VO2max in a normally weighted environment. Results: Two-way repeated measures analysis of variance showed a significant difference across trials, with trial 1 having a significantly higher VO2 than either trial 5 or 6. There were also differences across levels of unloading, as expected. Conclusions: The results of this study show that the unloading provided by the Alter-G treadmill is sufficiently novel that a minimum of 4-5 trials must be completed by the subject in order to obtain reliable metabolic cost of running on the device. Willis, Evan Brent Nelson Faculty mentor: Brent Nelson, College of Engineering, Forestry and Natural Sciences (CEFNS) Study of Calcium-Dependent Binding of Titin's N2A Region to Thin Actin Filaments Using Atomic Force Microscopy The purpose of this study is to advance the collective knowledge regarding titin in skeletal muscle contraction. The current sliding filament theory is generally accepted throughout the scientific community as a model describing muscle contraction. However, this model does not explain all the mechanical behavior of skeletal muscle. An alternative hypothesis, the “winding filament” model, states that in the presence of calcium ions in active muscle, a receptor in titin’s N2A region binds to actin filaments and is wound onto the filament during contraction. This study focuses on applying mechanical engineering knowledge and using an atomic force microscope (AFM) to measure the binding interaction between actin and the N2A region of titin. Titin fragments are attached to the AFM tip and brought into contact with actin filaments. The force to separate the two is then measured. Preparation for AFM imaging includes utilizing a fluid cell attachment to image filamentous actin in a salt buffer on epoxysilane-coated glass. For the final experiment, force measurements will be made with N2A region and calcium ion presences as variables. The impact of this research will be to provide data that supports or opposes the winding filament model. Acquisition of such data will also result in the broadening of fundamental knowledge of titin-actin interactions, as the results from this study will be used to springboard further research pertaining to titin-actin interactions. Furthermore, obtaining such knowledge could play an important role in the usage of the winding filament model for control systems in prosthetics. Wilson, Gregory Faculty mentor: Robyn Martin, Honors Program As of 4-19-13 UG Symposium Presentation Abstracts Pillars of Instability There is a commonly held notion that Afghanistan is the “graveyard of empires.” While purely sensationalist and in many degrees untrue, this saying gives an interesting perspective into Afghanistan itself. The “graveyard of empires” implies that foreign powers have tried, failed, and suffered as a result of intervening in this Central Asian country. Yet it ignores the plight of the average Afghan and the impact foreign powers have had. Through an ever growing pattern of invasion and intervention, Afghanistan has been in the hands of world powers over and over, in varying degrees. Despite our continued involvement, and reflections on previous interventions, have they really benefited from what we have forcefully given them? Afghanistan and its people have been given the part of a poor fool, strutting his way across the world stage to the tugs and yanks of a cruel puppeteer. Afghanistan is nothing but a victim of the conflict between the world powers, and in spite of its slow and painful modernization, these powers have done far more harm than good. Wilson, Gregory Faculty mentor: Grecthen Gee, College of Social and Behavioral Sciences (SBS) Dissolution of the State This paper will look at the reasons for the collapse and destabilization of the state and the empowerment of the nationalist movement. This failure to stay intact is a direct result of the state failing to create a coherent national identity, compounded with the empowerment of separatist movements through the application of ethnogenesis, imagined communities, and nation-building. Two examples will be used as a case study, the dissolution of the former Yugoslavia, and the ongoing struggle of the Kurdish people. Wilson, Janice Diane M. Stearns Faculty mentor: Diane Stearns, College of Engineering, Forestry and Natural Sciences (CEFNS) Detection of Heat- and Piperidine-Labile Sites in Plasmid DNA Exposed to Uranium Current work in our laboratory is investigating the ability of uranium to damage DNA in ways that may lead to cancer. We have previously shown that uranyl acetate (UA) is activated by ascorbate (vitamin C) or UV radiation to form DNA strand breaks. The purpose of the current project was to measure the adduct-type lesions in these reactions. Plasmid DNA was exposed to UA in the presence and absence of ascorbate, UVA light (368 nm), or UVB light (302 nm), and DNA damage was visualized by gel electrophoresis. Post-treatment incubations of DNA at RT, 60 °C or with 30 μM piperidine at 60 °C were carried out to measure the propensity of adducttype lesions to be converted to strand breaks. We hypothesized that if DNA adducts were present, than heat or piperidine would degrade more DNA compared to the same reactions in the absence of heat or piperidine. Results supported our hypothesis: DNA lesions produced by reactions of UA with ascorbate were heat sensitive, lesions from UA and UVA light exposures were piperidine-sensitive, and those from UA and UVB light exposures were neither heat- nor piperidine-sensitive. Results suggested that these reactions were synergistically damaging, but As of 4-19-13 UG Symposium Presentation Abstracts by different mechanisms. Therefore, U-DNA adducts may serve as a “parent lesion” for other types of secondary damage such as abasic sites and single strand breaks. This work is significant because it establishes a new method to explore potentially mutagenic U-DNA adducts. Funding was provided by NIH #ES019703 and #U54CA143925, and the NAU Ottens Program. Wiser, Jennifer Hannah Wall Faculty mentor: Kerri Quinn, Honors Program Music Makes Merry The purpose of this project is to make people smile through music.

Wolz, Frank Faculty mentor: Walter Vannette, College of Social and Behavioral Sciences (SBS) Archaeological uses of DNA The presentation is about how DNA, deoxyribonucleic acid, is used in modern archaeological research projects. The presentation looks into current archaeological digs that have been using DNA to determine either the evolution of humans or the domestication of animals. Another aspect in which DNA is used is to determine lineages in a group of people, and the data can be compared with genetic information from other locations around the world to piece together an evolutionary history of the human species. The presentation goes into how archaeology started incorporating DNA into the research procedure, and will also go into the future possible uses of genetics in archaeology. Wood, Stephanie Dr. Kevin Covey Faculty mentor: Kevin Covey, College of Engineering, Forestry and Natural Sciences (CEFNS) Mid-Infrared Variability and Color in Young Stellar Objects It is difficult to classify faint mid-infrared sources as protostars or background stars/galaxies without additional information. Multiple epochs of mid-IR data or sensitive near-infrared observations may be useful for understanding these objects and distinguishing between them. We studied multi-epoch Young Stellar Object Variability light curves to help differentiate between objects based on their variability. There was no clear separation in variability between the faint mid-infrared sources. We then analyzed the source’s colors by combining mid-infrared observations from the IRAC infrared survey with deep near-infrared data from the UKIDSS infrared survey and plotting a color-magnitude diagram. From this diagram we identified 288 candidate protostars in the Serpens Molecular Cloud; 217 of which are new identifications. Analysis of the multi-epoch mid-infrared CMD indicates that variability of most objects is As of 4-19-13 UG Symposium Presentation Abstracts consistent with what is expected from dust extinctions, supporting our conclusion that the identified candidate protostars lye within the Serpens Molecular Cloud. Wright, Kayla Faculty mentor: Egbert Schwartz, Anne Scott, College of Engineering, Forestry and Natural Sciences (CEFNS) Sir Paul Nurse's Discoveries on the Regulation of the Cell Cycle Sir Paul M. Nurse’s lecture, “Cyclin Dependent Kinases and Cell Cycle Control,” shows how Nurse came to discover how the cell cycle is controlled by certain genes that encode for proteins that regulate each phase of the cell cycle. Nurse focuses especially on the gene labeled cdc2. Nurse first discovers that in fission yeast, cdc2 is required for activating mitosis (the process by which a cell produces another cell), and for controlling the onset of S-phase (the phase in the cell cycle where DNA is replicated). Nurse then tries to discover the molecular role of cdc2, finding that it encodes for a protein kinase, and that this protein is encoded by other genes in other eukaryotes as well. Eventually, Nurse’s lab experiments lead to the ultimate discovery of how the protein cyclin and the protein kinase work collaboratively to regulate the cell cycle.

Yellowhorse, Miranda Erelda Gene Faculty mentor: Roger Bounds, Hendrik De Heer, Scot Raab, College of Health and Human Services (CHHS) Connecting the Circles and Creating a Path for Native American Student Success A comprehensive overview of the many academic success programs that support Native American & Alaskan Native students will be presented from a Native American student perspective. While there are many programs from various funding agencies available to AI/AN students, such programs are typically created to meet specific funding requirements and are created in isolation from each other. As a consequence, transitions between programs are challenging and there is no clear pathway for utilizing these programs to enhance academic success. For this project, descriptive characteristics of educational programs aimed at AI/AN students were compiled and organized by the academic level (pre-college, undergraduate, and As of 4-19-13 UG Symposium Presentation Abstracts graduate) for which the programs are designed. Analysis included the identification of overlaps in offerings and program outcomes as well as observations about commonalities in funding streams and populations served. Finally, suggestions are presented for future programing in relation to the promotion of resiliency among AI/AN students. This project offers a unique AI/AN perspective and interpretation of the availability and appropriateness of academic success programs designed for AI/AN students.

Zang, Ying Ying Zang Faculty mentor: Dean Smith, Franke College of Business (FCB) Water Desalinization Among the Earth's surface, almost 72% is covered by water while there is only a small part approximately 3% is fresh water and the rest is salt water. Desalinization is absolutely a good way to transfer salt water to fresh water and thus increase the fresh water supply. There are several methods for desalinization.Each has its benefits and cost. To analysis the revenue from the fresh water produced by desalinization method and the cost like the capital cost, operation cost and maintenance cost would be the key part of the project in order to judge if the desalinization industry can make profit and the method can be widely used. Zarcone, Kelly Faculty mentor: Jennifer Musial, Karla Hackstaff, College of Social and Behavioral Sciences (SBS) Art and Activism The presentation will be looking at how art, particularly street art, has challenged politics regarding public space and reclaimed voices that have been marginalized in dominant culture.

Zhou, Majun Long Li, Clinton Harris Faculty mentor: Joshua Hewes, College of Engineering, Forestry and Natural Sciences (CEFNS) As of 4-19-13 UG Symposium Presentation Abstracts American Society of Civil Engineers Student Competition Steel Bridge Design Team 2 The new Hill Music Hall and Marian Paroo Memorial Library sparked revitalization of the River City waterfront with restaurants, theaters, and luxury condominiums scrambling for space in the old brick warehouses. The River City Development Corporation (RCDC) is requesting design/build proposals for a bridge to provide direct access from suburbs across the river. In addition, the RCDC also requires the submittal of a 1:10 scale model capable of demonstrating the full-scale bridge properties. The bridge will be erected under simulated field conditions and will be tested for stability, strength, and serviceability using standardized lateral and vertical loads. The RCDC has selected a panel of engineers to judge the models by multiple criteria including durability, constructability, usability, stiffness, construction speed, efficiency, economy, and attractiveness according to the ASCE/AICS Steel Bridge Competition Rules. The bridge will need to provide direct access from suburbs across the river in RCDC. Accelerated Bridge Construction (ABC) is mandated in order to minimize travel delays and financial losses to waterfront businesses caused by disruption of traffic during construction. The bridge will provide clearance for tour boats, and will cantilever over the historically significant billiard parlor. RCDC specifies steel because fast erection is essential to ABC, and because steel’s durability and high level of recycled content contribute to exceptional sustainability. The total width of the river is 120 ft. One side of the bridge necessitates the use of a cantilever. The distance between the bridge and the bridge construction material storage area is limited. Zhou, Wuke Faculty mentor: Astrid Klocke ___________________________, College of Arts and Letters (CAL) Chinese Genre Film Rises During last Chinese New Year, one particular film seized every Chinese filmmaker's attention. The film is called "Lost in Thailand", directed and performed by Zheng Xu, one of the famous Chinese comedy actors. This film, which the total cost was no more than 400 million dollars, brings him 2 billion box-offices that defeats every other director at the time and becomes the most popular commercial movie in China. The success of Xu is considered the success of genre film by most of Chinese film critics. The concept of genre film has not been bring to China not until recently, but this concept grabs media’s attention almost immediately after the success of Xu. Most Chinese people wonder what it is and how it can cause such a great influence on commercial success. In my presentation, I’ll compare other two famous directors, Xiaogang Feng, and Yimou Zhang with Xu’s lastest success. By comparing their works to Xu, we can see noticeably how Chinese audience becomes much mature about choosing films and gradually seeking for “genre” films instead of “director style” films.
