Description
Analysis of political texts, which contains a huge amount of personal political opinions, sentiments, and emotions towards powerful individuals, leaders, organizations, and a large number of people, is an interesting task, which can lead to discover interesting interactions between the political parties and people. Recently, political blogosphere plays an increasingly important role in politics, as a forum for debating political issues. Most of the political weblogs are biased towards their political parties, and they generally express their sentiments towards their issues (i.e. leaders, topics etc.,) and also towards issues of the opposing parties. In this thesis, I have modeled the above interactions/debate as a sentimental bi-partite graph, a bi-partite graph with Blogs forming vertices of a disjoint set, and the issues (i.e. leaders, topics etc.,) forming the other disjoint set,and the edges between the two sets representing the sentiment of the blogs towards the issues. I have used American Political blog data to model the sentimental bi- partite graph, in particular, a set of popular political liberal and conservative blogs that have clearly declared positions. These blogs contain discussion about social, political, economic issues and related key individuals in their conservative/liberal view. To be more focused and more polarized, 22 most popular liberal/conservative blogs of a particular time period, May 2008 - October 2008(because of high intensity of debate and discussions), just before the presidential elections, was considered, involving around 23,800 articles. This thesis involves solving the questions: a) which is the most liberal/conservative blogs on the web? b) Who is on which side of debate and what are the issues? c) Who are the important leaders? d) How do you model the relationship between the participants of the debate and the underlying issues?

Description
In 2004, the South Korean geneticist Woo-Suk Hwang published what was widely regarded as the most important research result in biotechnology of the year. In the prestigious American journal Science, he claimed that he had succeeded in cloning a human blastocyst, an embryo in its early stages (Hwang et al. 2004). A year later, in a second Science article, he made the earth-shattering announcement that he had derived eleven embryonic stem cell lines using his cloning technique (Hwang et al. 2005). The international scientific community was stunned. American scientists publicly fretted that President George W. Bush‘s 2001 executive order limiting federal funding for stem-cell research in the United States had put American bioscience behind the Koreans‘ (Paarlberg 2005). These breakthroughs offered potential solutions to immune system rejection of transplanted organs and possible cures for diseases such as rheumatoid arthritis, Parkinson‘s, Down‘s syndrome, and paralysis (Svenaeus 2007). However, within a year, Hwang was exposed as a fraud who had faked his results and pressured his female colleagues to donate eggs without informed consent. Despite protests against his methods from Korean religious and nongovernmental organizations, Hwang had used his prestige to ignore his ethical obligations. The Korean government, too, was slow to investigate Hwang and to subject his work to appropriate regulation.

Description
The NCAA recently declared sickle cell trait (SCT) to be a risk factor for sudden illness and death among student athletes. Fetal hemoglobin (HbF) concentration in adults is negatively correlated with disease severity in sickle cell anemia, although its effect on SCT is not fully understood and the concentration is found to have high variability across populations. Two single nucleotide polymorphisms (SNPs) at the human beta globin gene cluster, rs7482144 and rs10128556, contribute to the heritable variation in HbF levels and are associated with increased HbF concentrations in adults. A sample population of NCAA football student athletes was genotyped for these two polymorphisms, and their allele frequencies were compared to those of other populations. The minor allele of both polymorphisms had allele frequencies of 0.091 in the sample population, which compared closely with other populations of recent African heritage but was significantly different from European populations. The results of this study will be included in a larger study to predict whether these among other polymorphisms can be used as markers to predict susceptibility to heat-related emergencies in NCAA student athletes with SCT, although the small sample size will delay this process until participation in the study increases. Since both rs7482144 and rs10128556 exhibit high levels of linkage disequilibrium, and as their contributions to the heritable variability of HbF concentrations tend to differ greatly between populations of different ancestry, further investigations should be aimed at distinguishing between the effects of each SNP in African American, European, and other populations represented in NCAA football before conclusions can be drawn as to their practical use as genetic markers of heat susceptibility in student athletes with SCT.

Description
Protein is an essential macronutrient in the human diet, but the source of this protein has both human health and environmental impacts. Health complications can result from protein deficiency, but the practices by which protein sources are raised, grown, or harvested have environmental consequences, potentially reducing biodiversity, essential habitat, and crucial stocks of natural resources. Terrestrial cultivation encroaches on natural habitats and consumes resources inefficiently, while overfishing has greatly depleted wild fishery stocks. These environmental factors, along with concerns about nutrients, contaminants and the ethics of animal protein has led to confusion about weighing the risks and benefits associated with alternative sources of protein. Providing consumers \u2014 and policy makers \u2014 with a comprehensive account of major protein sources and their impacts in an understandable form is crucial to reducing environmental degradation and improving human health. Here I provide a general framework to compare the health and environmental impacts of livestock, seafood, and plant protein, and illustrate the application of this framework with case studies for each of these categories.

Description
BACKGROUND: Biotechnology can improve vitamin deficiencies, farming practices and yields, yet it is surrounded by controversy. PURPOSE: The purpose of this study was to better understand opinions Americans have about genetically modified organisms (GMOs), across multiple perspectives including scientists, farmers, and perceptions shared via social media. METHODS: A Google Scholar search for the term "genetically modified" (GM) produced 1,420,000 results in 0.05 seconds from the year 1988 to present, a portion of this literature was used for this study. In addition a quasi-experimental study on social media (i.e. a blog and Twitter) was performed to inspire reactions of social media users who followed the accounts @Biofortified and @BiotechFood. The study lasted for approximately three months. The analytics website, Topsy was also used to track the number of conversations that included terms like "GMO". Furthermore a plant biologist, sustainability scientist, and local farmers were interviewed to gain insights on their perceptions of GM products. RESULTS: Results generally suggest that there was no stance shared by social media users, local farmers, and researchers. It was clear however that conversation about GMOs happens daily on social media. These conversations however lack the evidence that can be learned through literature and conversations with local farmers. DISCUSSION: A plausible possible reason for the confusion and mixed opinions is that regardless of the resources (like scientific literature and agriculture workers available on GMOs), individuals appear to use moral reasoning \u2014 as defined by Jonathan Haidt \u2014 to defend their stance on GMOs, not necessarily any empirical evidence.

Description
The transition from high school to college is, for many, a drastic change in lifestyle, social networks, and dietary choices. The prevalence of obesity in college students has been steadily increasing. Freshmen weight gains have been associated with a decrease in fruits and vegetables and an increase in unhealthy items such as desserts, alcohol, and late night snacking after dinner. A survey of college students was constructed to gauge students' perceptions of nutrition how these perceptions influenced dietary practices and behaviors. Survey results indicated that awareness of nutrition and health does not translate to dietary practices, aligning with results from previous studies. Several sex differences were noted in regards to dietary choices and perceptions, knowledge seeking behavior, and sources of information. While there were some similarities, it is clear from the results obtained that men and women have different approaches and thoughts with regard to nutrition. The results showed that college students who actively seek our nutritional information are more likely to do so in the form of social media or Internet sources. This study could be useful for those planning on conducting college-based nutritional programs in that the results indicate patterns and trends that should be taken into consideration in order for a successful nutrition intervention

This thesis explores how we can harness new technology to improve our relationship with companion animals and promote shelter animal welfare. The study looked into using the photo-sharing application Instagram to increase adoption rates at the Arizona Animal Welfare League & SPCA. An Instagram page was created and managed for the shelter, and data was collected regarding the impact the page had on adoption rates. The results were mixed, but overall it was determined that the Instagram page has unique value for the shelter.

Description
This thesis project utilizes a multi-frame analysis from Bolman and Deal’s Reframing Organizations: Artistry, Choice and Leadership to reinvent a fundraising opportunity for a nonprofit organization named Save the Cats Arizona. This thesis begins with what makes Save the Cats Arizona stand out from other organizations. From there, a breakdown of the organization’s structure is provided. Next, research is provided on the impacts of fundraising on social media platforms and online engagement across nonprofit organizations. Additional research is provided to highlight the importance of social media management in nonprofit organizations. Save the Cats Arizona is then analyzed through Bolman and Deal’s multi-frame theory – which includes the structural, human-resource, political, and symbolic frame. Finally, the knowledge gained from the multi-frame analysis is implemented into ideas on how to improve fundraising opportunities for Save the Cats Arizona. This project ends with a reflection about this thesis and Save the Cats Arizona’s future.

Description
The purpose of this cookbook and ingredient index is to simplify the reasoning behind eating a plant based diet--including how it can be beneficial to your health, and what benefits each ingredient provides. These recipes have been cultivated and modified over time to provide nutritious meals that are also tasty. I was introduced to healthy eating at a young age, and have been fascinated by it ever since. The recipes and information conveyed about a plant based diet have come from the many books read and research I have done on the subject. This paper will walk you through how I started this journey, and go on to show a basic overview of what makes up the foods we consume and why we need them. The cookbook portion of my Thesis contains recipes for breakfast, lunch, dinner, snacks, sauces, and dessert. Following the cookbook is an ingredient index that goes through the majority of ingredients used in my recipes, and what health benefits they provide. I hope that by reading this, others will be inspired to use more plant-based whole foods in their diet, and realize the healing that can come from them.
