Description
Two primary contexts for the adaptive evolution of bright coloration are competition for mates (i.e. mate choice) and avoiding predator attacks (i.e. warning coloration). Bright animal coloration can be iridescent, in which the surface appears to change color with changing viewing or illumination angle. Bright animal coloration can also be produced by pigments, which do not appear to change color with changing viewing or illumination angle. The Pipevine Swallowtail, Battus philenor, is unique in having both sexual signals and warning coloration that include iridescent and pigment components, both of which are variable in color. The aim of our study was to examine the role genes play in producing this variation, providing us a sense of potential indirect benefits of female choice. We tested the hypothesis that color variation has a genetic component. We predicted that in a full-sib analysis there should be greater variation in the coloration of the sexual and warning signal among families than within families. We reared B. philenor under standard laboratory conditions and analyzed heritability using a full-sib analysis. We collected reflectance measurements for components of the sexual and warning signal iridescence using a spectrophotometer and used CLR (color analysis software) to extract brightness, hue, and chroma values. We used a multivariate ANOVA (IBM SPSS, v. 21) to analyze the warning signal variation, and a generalized linear mixed model (IBM SPSS, v. 21) to analyze the sexual versus warning signal variation in males. A significance value of 0.05 was used for both analyses. Our results indicated a genetic component to coloration, implicating indirect benefits in B. philenor female mate bias. Further research on bright coloration in B. philenor indicates that there may also be direct benefits of female mate choice.

Description
This project looks at the effects of American sanctions on the Sudanese economy. The purpose of the research is to evaluate the effects of the sanctions on the GDP (based on Purchasing Power Parity) of Sudan using linear regression analysis. We used a linear model to conduct analysis that included variables such as Sudan's trading partners, distance between Sudan and said partners, the GDP of these other countries, and whether there are sanctions imposed. The data collected runs from 1980 to 2011 \u2014 the year South Sudan became independent. The results of the analysis indicate that sanctions are ineffective in achieving their purpose which is ending the human rights violations in Sudan. The findings are consistent with arguments put forth by economics for decades.

Description
Dental caries also known as tooth decay is a bacterial infection that causes demineralization and destruction of enamel dentin and cementum in the tooth. This bacterium, Streprococcus mutans, feeds on the carbohydrates in the mouth and produces lactic acids that result in dental caries. This thesis discusses the use of plants to produce antibodies, Guy 13 and anti-GTFB to treat this dental disease. We believe these plant-derived antibodies will be effective to treat dental caries and economical to produce.

Description
"Seventy five percent of the world's poor live in rural areas of developing countries, where most people's livelihoods rely directly on agriculture." (USAid, 2014) Reduced levels of crop production and the accompanying problems of malnourishment exist all over the world. In rural Peru, for example, 11 percent of the population is malnourished. (Global Healthfacts.org, 2012) Since the success in agriculture relies importantly on the fertility of the soil, it is imperative that any efforts at reversing this trend be primarily directed at improving the existing soils. This, in turn, will increase crop yields, and if done properly, will also conserve natural resources and maximize profits for farmers. In order to improve the lives of those at the bottom of the pyramid through agriculture, certain tools and knowledge must be provided in order to empower such persons to help themselves. An ancient method of soil improvement, known as Terra Preta do Indio (Indian dark earth), was discovered by Anthropologists in the 1800's. These dark, carbon-rich, soils are notable for their high fertility, high amounts of plant available nutrients, and their high moisture retention rates. The key to their long-lasting fertility and durability is the presence of high levels of biochar, a highly stable organic carbon \u2014 produced when organic matter (crop residues, food waste, manure, etc.) is burned at low temperatures in the absence of oxygen. Research has shown that when charcoal (biochar) and fertilizers are combined, it can yield as much as 880 percent more than when fertilizers are used by themselves.

Description
Microarthropods play important roles in the decomposition process of the detrital food web, where they break down organic matter and return nutrients to the soil. However, only a small percentage of the belowground microarthropod population has been studied or even discovered, leading to a decrease in the knowledge of all of the processes carried out by these organisms and their importance to the soil. This is because microarthropod extraction methods are not 100% effective at collecting specimens. This study aimed to find an ideal quantitative procedure to better record the number of microarthropods existing in the soil and to determine if a seasonal variation exists that effects the success of extraction. Two extraction methods, including dynamic extraction and heptane flotation extraction, were compared across two seasons, a dry season (June) and a wet season (September). Average biomasses and average richness were calculated for four different functional groups, including Prostigmata, Mesostigmata, Cryptostigmata, and Collembola, across the two seasons, and statistical analysis was performed to determine if any differences that existed were statistically significant. Results indicate that the dynamic extraction method was significantly more effective for the collection of microarthropods during the wet season, and the heptane extraction method was significantly more effective during the dry season. In addition, the heptane procedure recovered samples of higher average richness than the dynamic method during both seasons. The heptane procedure works best for extraction during the dry season because it is able to collect organisms that entered into an ametabolic anhydrobiotic state to escape desiccation. These organisms form a protective lipid layer around their exoskeletons to retain water, and the non-polar exoskeletons display a chemical affinity to the heptane fluid, allowing for collection out of the soil and into the heptane layer. Despite these results, no one method is entirely superior to the other, and the most efficacious procedure depends on the researcher's aim of study.

Description
The increasing civilian demand for autonomous aerial vehicle platforms in both hobby and professional markets has resulted in an abundance of inexpensive inertial navigation systems and hardware. Many of these systems lack full autonomy, relying on the pilot's guidance with the assistance of inertial sensors for guidance. Autonomous systems depend heavily on the use of a global positioning satellite receiver which can be inhibited by satellite signal strength, low update rates and poor positioning accuracy. For precise navigation of a micro air vehicle in locations where GPS signals are unobtainable, such as indoors or throughout a dense urban environment, additional sensors must complement the inertial sensors to provide improved navigation state estimations without the use of a GPS. By creating a system that allows for the rapid development of experimental guidance, navigation and control algorithms on versatile, low-cost development platforms, improved navigation systems may be tested with relative ease and at reduced cost. Incorporating a downward-facing camera with this system may also be utilized to further improve vehicle autonomy in denied-GPS environments.

Abstract "Empty Horizons": A Creative Writing Piece Max Harmon "Empty Horizons" is a creative writing piece composed of two different short stories sharing a common narrator. The first story "Can you dig it?" details a trip the narrator takes to South Dakota to go hunting shortly before starting college. On the trip the narrator contemplates certain aspects of his life and the events of the story serve as a vehicle to explore the narrator's mindset as an eighteen year old about to start a new phase in his life. The second story "Toads, Sharks and Beautiful Encounters with Uncertainty" takes place during the summer before the narrator begins his last semester in college as he attends the funeral of his recently deceased grandmother in Hawaii. During the trip to Hawaii, the narrator meets a girl his age and they are able to bond with each other over feelings of loss and uncertainty. In this story the narrator explores his feelings about life with college graduation on the horizon and comes to terms with some of the anxieties that have been plaguing him since the start of college. By detailing these two distinct and important time periods in the narrator's life the reader is able to gain a sense of understanding in regards to the narrator's own process of beginning life as an adult.

Description
With the population size growing rapidly at Arizona State University, students are more likely to get sick and miss school when living on campus. The purpose of this project was to design a mobile web application called, SeeSick, that would visualize the spread of illness on the ASU Tempe campus. This application would provide students with information that could help prevent the spread of illness and allow them to take actionable steps for staying healthy. To accomplish the design and testing of this application, research was conducted on how technology is currently used by students when they are sick, how to design an effective user interface for ASU students, how to physically visualize the spread of the flu on an app, and if an application like this would be useful. The visualizations are created from a user input form and from Twitter data scraping and are displayed on a heat map of the Tempe campus. 126 students were surveyed before the development of the application and once the application was functional, 87 students were interviewed for user testing. Through trial-and-error design and testing, the application was analyzed to determine if it would be used and change behavior. The design of SeeSick successfully provided users with a way to visualize the spread of symptoms on campus and presented them personalized feedback about their symptoms. 62% of students interviewed found the application to be useful and 84% of participants found it easy to use. However, 57% of students said their behavior would not change while using SeeSick. Of the students who tested the application, SeeSick was found to be useful, easy to use, but would not cause behavior change. The current version supports the goal to create a mobile application that tracks the spread of the flu on campus, however it was not tested enough to determine if it would change behavior. With further development and larger testing groups, SeeSick could be improved to not only track the spread of illness on a hyper-local level, but also create actionable steps to prevent the spread of illness.

Description
Based upon personal involvement from August 2010 to July 2014 as a Marine Option Midshipman within the ASU Naval Reserves Officer Training Corps (NROTC), being a student of leadership training within my degree plan, and gender difference research I conducted, this creative project addresses potential issues that reside within the ASU NROTC and the ways in which the program overall can be changed for the Marine Options in order to bring about proper success and organization. In order to officially become a Marine within the Unites States Marine Corps, it is necessary for Marine Option students to fulfill Officer Candidate School (OCS) at Quantico, Virginia. As the first female to go through OCS as a midshipman from the ASU NROTC, I found that there is an inadequate amount of preparation and training given in regards to the gender differences and what is to be expected for successful completion. I will offer a brief history regarding the NROTC across the Unites States and the ASU NROTC itself. These subjects will cover the program layouts as well as the leadership training that is required and provided within it and the ways in which this is conducted. I will then compare and contrast this to the leadership training given to me within my study of Leadership and Ethics regarding the transformational leadership, gender-based leadership, and coercive leadership. Finally, I end my thesis with a reflection of personal experiences taken away from these avenues and offer recommendations to better equip the ASU NROTC program in having successful retention and success of the female Marine Option midshipman.

Description
Since the inception of the World Wide Web in the late 1980s, public relations firms and their clients have benefited from a valuable platform allowing for instant and global communication. Essential social engagement tools such as trust, loyalty and information dissemination have been transferred from a physical, non-mediated environment to a virtual, technology mediated one. Therefore, it is now vital that public relations practitioners understand the emerging field of cyberpsychology and the important elements that nurture e-Trust, e-Loyalty and Positive Virality. Through qualitative research methods, e-Trust, e-Loyalty and Positive Virality are comprehensively and conceptually defined. Each is also operationally defined in terms of number of users, number of followers and number of tweets, shares or media impressions. A Cyber-Success Model is proposed as a way to explain how these three digital components may work together to achieve a high degree of public engagement. The specific conceptual and operational criteria as well as the Cyber-Success Model are then used to evaluate public engagement with regard to Edelman Digital campaigns executed for clients PayPal and Ebay as examples of how the model is applied. Conclusions and future recommendations for Edelman Digital, the field of public relations and the field of cyberpsychology are discussed.
