Description
Economists, political philosophers, and others have often characterized social preferences regarding inequality by imagining a hypothetical choice of distributions behind "a veil of ignorance". Recent behavioral economics work has shown that subjects care about equality of outcomes, and are willing to sacrifice, in experimental contexts, some amount of personal gain in order to achieve greater equality. We review some of this literature and then conduct an experiment of our own, comparing subjects' choices in two risky situations, one being a choice for a purely individualized lottery for themselves, and the other a choice among possible distributions to members of a randomly selected group. We find that choosing in the group situation makes subjects significantly more risk averse than when choosing an individual lottery. This supports the hypothesis that an additional preference for equality exists alongside ordinary risk aversion, and that in a hypothetical "veil of ignorance" scenario, such preferences may make subjects significantly more averse to unequal distributions of rewards than can be explained by risk aversion alone.

Description
Cardiovascular disease (CVD) is the primary killer of Americans. As such, alternative means of a dietary approach to preventing or mitigating the development of CVD is clearly needed in addition to the ongoing recommendation for increased consumption of fruits and vegetables. Many studies suggest that fungi have the potential to decrease morbidity and mortality associated with CVD. Specifically, white button mushrooms, viz., Agaricus bisporus, are fairly common and inexpensive and full of untapped possibilities for efficacy although much additional research is needed. With antioxidants, e.g., selenium, and beta-glucans, viz., indigestible polysaccharides, white button mushrooms contain a plethora of bioactive ingredients that confer a potentially strong tool against the debilitating social impact of CVD.
The objective of this thesis was to establish protocols and a valid experimental design for testing whether dietary mushrooms could, in fact, be protective against CVD risk. Specifically, a case-study approach was used to validate this experimental method to test white button mushrooms and their impact on blood lipid levels and the inflammatory response. This dietary study involved preparation of two soups: a placebo, broth-based soup and one with one cup of white button mushrooms per cup of soup to provide one and a half cups of soup (and mushrooms) per day to each participant. The soup was prepared in The Kitchen Café at the ASU Downtown Campus (Phoenix, AZ).
After preparing the soup, the next goal was recruitment through listserv, local advertisements, flyers, and word of mouth of participants to test the overall plan. Over fifteen people responded; however, only one candidate met the inclusion criteria of someone at high risk of developing CVD and agreed to participate in the study. The participant visited the nutrition laboratory in downtown Phoenix (550 N. 5th Street). Anthropometric data and an initial blood draw were completed, and fourteen 1.5 cup containers of mushroom soup were dispensed to the participant. After two weeks, the individual returned and the same procedures were executed to include anthropometry and blood analysis. Even though the subject did not show changes in blood markers of CVD risk (lipids and inflammatory markers), the hypothesis for the thesis that the study design would be effective was accepted. Thus, the procedure was successful and validated and will be used in the future study.

Description
Issues of visitor safety are a concern among park and recreation managers. As urban parks receive a variety of user groups, understanding perceptions of safety among specific groups becomes pertinent when managing for optimal experiences. This study examines trails runners at two mountain parks in a large southwestern city. Data was collected in the fall of 2013 and the spring of 2014 using a five page, onsite, self-administered, exit survey in English. Questions addressed trail runner demographics, level of trail running experience, perceptions of safety, and support for safety related management actions. Of specific interest was how perceptions of safety varied by trail runner demographics and level of experience. 102 trail runners participated in the study. Data analysis was completed using an independent samples t-test to compare sample characteristics with perceptions of safety and safety related management actions. The results include mixed opposition and support for specific preventive management actions. Few significant differences in responses were found between gender, age and specialization. The findings also suggest trail runners primarily learned about these recreation areas through local knowledge and "word of mouth" and not through managers. Further implications of these finding is discussed. Contributions of the study are twofold. First, results provide managers with information regarding trail runners at the parks. Second, findings serve to extend the literature on visitor safety at park and recreation settings in urban areas.

Description
This paper examines infrastructure spending in a model economy. Infrastructure is subdivided into two types: one that makes future production more efficient, and another that decreases the risk of devastation to the future economy. We call the first type base infrastructure, and the second type risk-reducing infrastructure. Our model assumes that a single representative individual makes all the decisions within a society and optimizes their own total utility over the present and future. We then calibrate an aggregate economic, two-period model to identify the optimal allocation of today’s output into consumption, base infrastructure, and risk-reducing infrastructure. This model finds that many governments can make substantive improvements to the happiness of their citizens by investing significantly more into risk-reducing infrastructure.

Description
The Philippines relies on a vast biodiversity of fishes as a staple food, but like many countries around the globe, experiences severe “leakages” of contaminants and pollutants in the environment. In order to better understand the relationship between environmental pollutants and public health, this research project measured the concentration of pollutants in a commonly consumed local fish (Siganus fuscescens), and then evaluated the potential health risks of eating this fish based on estimated average consumer weight and consumption levels. Fish sampled from four different sites located in Negros Oriental, Philippines were analyzed for organic contaminants using gas chromatography and mass spectroscopy. Pollutants quantified included polycyclic aromatic hydrocarbons (PAHs), pesticides, phthalates, and polychlorinated biphenyl (PCBs). Across the four study sites, fishes from Manjuyod showed the highest frequency of detection of different pollutants. However, phthalates and PAHs were found in similar concentrations in all four sites, with fishes from Dumaguete showing the highest level of PCBs compared to the other sampled sites. The U.S. Environmental Protection Agency’s guide for fish contaminants pinpoints several health risks associated with the chronic ingestion of these contaminants. Based on estimated average body weights of Filipino adult men, adult women, and children, and various consumption levels, people who eat the fish at or above the national average consumption level may be at increased risk for chronic health outcomes, such as cancer and/or other adverse effects. Specifically, due to the high concentration of PCBs in Dumaguete, selected populations who eat local fish from this site may be at higher risk than the citizens who eat the fish from other sites at similar consumption rates. These results can help to inform local and national policies on water quality, waste disposal, and fish consumption advisory programs.

Description
Dr. Dean Kashiwagi created a new thinking paradigm, Information Measurement Theory (IMT), which utilizes the understanding of natural laws to help individuals minimize decision-making and risk, which leads to reduced stress. In this new paradigm, any given situation can only have one unique outcome. The more information an individual has for the given situation, the better they can predict the outcome. Using IMT can help correctly "predict the future" of any situation if given enough of the correct information. A prime example of using IMT would be: to correctly predict what a young woman will be like when she's older, simply look at the young woman's mother. In essence, if you can't fall in love with the mother, don't marry the young woman. The researchers are utilizing the concept of IMT and extrapolating it to the financial investing world. They researched different financial investing strategies and were able to come to the conclusion that a strategy utilizing IMT would yield the highest results for investors while minimizing stress. Investors using deductive logic to invest received, on average, 1300% more returns than investors who did not over a 25-year period. Where other investors made many decisions and were constantly stressed with the tribulations of the market, the investors utilizing IMT made one decision and made much more than other investors. The research confirms the stock market will continue to increase over time by looking at the history of the stock market from a birds-eye view. Throughout the existence of the stock market, there have been highs and lows, but at the end of the day, the market continues to break through new ceilings. Investing in the stock market can be a dark and scary place for the blind investor. Using the concept of IMT can eliminate that blindfold to reduce stress on investors while earning the highest financial return potential. Using the basis of IMT, the researchers predict the market will continue to increase in the future; in conclusion, the best investment strategy is to invest in blue chip stocks that have a history of past success, in order to capture secure growth with minimal risk and stress.

Description
Terrestrial crude oil spills compromise a soil’s ability to provide ecosystem services by inhibiting plant life and threatening groundwater integrity. Ozone gas, a powerful oxidant, shows promise to aid in soil recovery by degrading petroleum hydrocarbons into more bioavailable and biodegradable chemicals. However, previous research has shown that ozone can change the soil pH and create harmful organic compounds.
The research objective was to determine the short-term ecological toxicity of ozonation byproducts on seed germination of three distinct plant types (radish, lettuce, and grass) compared to untreated and uncontaminated soils. We hypothesize that the reduction of heavy hydrocarbon contamination in soil by ozone application will provide more suitable habitat for the germinating seeds. The effect of ozone treatment on seed germination and seedling quality was measured using ASTM standards for early seedling growth in conjunction with a gradient of potting soil amendments. Ozonation parameters were measured using established methods and include total petroleum hydrocarbons (TPH), dissolved organic carbon (DOC), and pH.
This study demonstrated the TPH levels fall up to 22% with ozonation, suggesting TPH removal is related to the amount of ozone delivered as opposed to the type of crude oil present. The DOC values increase comparably across crude oil types as the ozonation dose increases (from a background level of 0.25 g to 6.2 g/kg dry soil at the highest ozone level), suggesting that DOC production is directly related to the amount of ozone, not crude oil type. While ozonation reduced the mass of heavy hydrocarbons in the soil, it increased the amount of ozonation byproducts in the soil. For the three types of seeds used in the study, these changes in concentrations of TPH and DOC affected the species differently; however, no seed type showed improved germination after ozone treatment. Thus, ozone treatment by itself had a negative impact on germination potential.
Future research should focus on the effects of post-ozonation, long-term bioremediation on eco-toxicity. By helping define the eco-toxicity of ozonation techniques, this research can improve upon previously established ozone techniques for petroleum remediation and provide economic and environmental benefits when used for soil treatment.

Description
As undergraduate students focus on the perceived adventure, growth opportunities, social connections, freedom and fun, they may not be aware of the dangers and risks associated with studying abroad. Despite university-created crisis prevention measures such as policies, documentation, and orientations warning of the risk of travel, students who study abroad face some form of a crisis every year. Universities warn travelers of the dangers of crime and the psychological issues associated with liminal experiences and culture shock, preparing students for the harsh reality that immersion into a foreign culture is an intense and sometimes taxing experience. Faculty and staff dedicate a tremendous amount of time and energy to ensure our students are braced for their travel experience, yet students still experience immense hardships. In a comprehensive analysis of this phenomenon, we seek to find and explore reasons and variables that account for this chasm. We suspect the reason for this chasm, despite good efforts, is the variance between the resources that are provided and needed both upon entry into host country, and re-entry into native country. In extensively reviewing existing scholarly literature, reviewing case studies, conducting examinations of multi-causal variables, and analyzing measurable data, we suggest that study abroad preparation resources must adapt in order to accommodate an ever-evolving undergraduate tourist experience. In Section I the research team provides an introduction and underscores the central question of the study. Section II includes an extensive literature review in order to establish a definition of culture shock, determine what universities currently do to mitigate culture shock and risk, and assess the efficacy of these strategies. The research team subsequently identifies a lacuna -- the gap or point of departure from existing literature and research that this study seeks to fill. Section III presents our hypothesis, while Section IV offers an outline of precise Methodology. Section V includes an in-depth Data Analysis using findings dependent upon surveys and interviews as discussed in Methodology. Section VI presents policy recommendations or a “fix” based upon findings presented in Data Analysis. Section VII presents a conclusion, offering a culmination of deductions and implications, proving the relevance of this study to Arizona State University.

Description
Current conservation practices are substantially biased towards large, charismatic animals and are influenced by public perceptions of different animals. Therefore, it is important to understand how these perceptions are formed and what factors influence them in order to promote equitable conservation for all species. This study examines the effect of attending a park education program on public values, knowledge of, and attitudes towards a noncharismatic species. Data was collected from May through October 2016 at the Usery Mountain Regional Park "All About Scorpions" program. A four page, onsite, self-administered pre- and post-program survey was given to program attendees. An identical survey was given to hiking park visitors who had never attended the program as the control sample. Survey statements addressed participant's demographics, value of bugs, knowledge about scorpions, and attitudes toward scorpions. Data analysis was completed using paired t-tests to analyze any statistically significant changes in values, knowledge, and attitudes between pre- and post-participants. Independent sample t-tests were used to analyze the same between the control and pre-participants. The results showed no difference in the value of bugs for any of the survey participants. However, the program attendees had more positive attitudes and greater knowledge of scorpions than general park visitors, and attending the program further increased positive attitudes and knowledge. Contributions of the study are twofold: First, the results provide Usery with information regarding the influence of their public programs, along with how these programs can be improved to make a greater impact. Second, findings serve to extend the literature on what alters public perceptions and how educational programs can be used to change the current conservation mindset.

Description
There are two common cognitive distortions present in risky decision-making behavior. The gambler's fallacy is the notion that a random game of chance is potentially biased by previous outcomes, and the near-miss effect is the overestimation of the probability of winning immediately after barely missing a win. This study replicated a portion of the methods of Clark et al. (2014) in an attempt to support the presence of these two fallacies in online simulated risky decision-making tasks. One hundred individuals were recruited and asked to perform one of two classic gambling tasks, either predict the outcome of a dichromatic roulette wheel or spin a simplified, two-reel slot machine. An analysis of color predictions as a function of run length revealed a classic gambler's fallacy effect in the roulette wheel task. A heightened motivation to continue playing after a win, but not a near or full miss, was seen in the slot machine task. How pleased an individual was with the results of the previous round directly affected his or her interest in continuing to play in both experiments. These findings indicate that the gambler's fallacy is present in online decision-making simulations involving risk, but that the near-miss effect is not.
