Description
Space microbiology, or the study of microorganisms in space, has significant applications for both human spaceflight and Earth-based medicine. This thesis traces the evolution of the field of space microbiology since its creation in 1935. Beginning with simple studies to determine if terrestrial life could survive spaceflight, the field of space microbiology has grown to encompass a substantial body of work that is now recognized as an essential component of NASA' research endeavors. Part one provides an overview of the early period of space microbiology, from high-altitude balloon and rocket studies to work conducted during the Apollo program. Part two summarizes the current state of the field, with a specific focus on the revolutionary contributions made by the Nickerson lab at the Biodesign Institute at ASU using the NASA-designed Rotating Wall Vessel (RWV) Bioreactor. Finally, part three highlights the research I've conducted in the Nickerson lab, as well as continuing studies within the field of space microbiology.

Description
In everyday life, mental fatigue can be detrimental across many domains including driving, learning, and working. Given the importance of understanding and accounting for the deleterious effects of mental fatigue on behavior, a growing body of literature has studied the role of executive control processes in mental fatigue. In a laboratory setup, participants complete a task that places demands on executive control processes and are later given a transfer task. Generally speaking, decrements to subsequent task performance are taken as evidence that the initial executive control task created mental fatigue through the continued engagement of executive control. Several hypotheses have been developed to account for negative transfer resulting from executive control depletion including cognitive resource depletion and task-switching. In the current study, we provide a brief literature review, specify current theoretical approaches to depletion, and provide a strong empirical test of theories for negative transfer from executive control depletion (i.e., does continued performance of an executive control task negatively transfer to that exact same task).

Description
While the concept of healthcare is largely respected in Arab culture, the stigma underlying mental health is particularly startling. This study examined the differences in mental health treatment-seeking behaviors using data from Arabs living in Syria (12.9%) and Arabs (25.6%) and non-Arabs (61.5%) living in the United States of ages 18-60. A Web-based survey was developed to understand how factors like religiosity, acculturation, and positive attitudes towards psychological treatment increased help-seeking behaviors. This survey was also provided in Arabic to include non-English speaking participants. It was hypothesized that Arab-American individuals will be more open to pursuing professional psychological help when suffering from mental symptomology (i.e. anxiety) than individuals who identified as Syrian-Arabs. In contrast, both Syrian-Arabs and Arab-Americans would definitely pursue professional help when suffering from physical symptomology (i.e. ankle sprain). Striking differences were found based on Western acculturation. Findings suggested that Arab-Americans were less inclined towards treatment and more trusting of an in-group physician ("Dr. Ahmed") whereas Syrian-Arabs were more inclined to pursue psychological treatment and preferred to trust an out-group physician ("Dr. Smith"). The results of this study identify main concerns regarding Arab attitudes towards seeking mental health treatment, which can better inform future research and mental health services for this minority.

Description
Breast cancer affects hundreds of thousands of women a year in the United States, and kills tens of thousands. African-American women experience a lower incidence of breast cancer, yet they die at twice the rate of Caucasian women. This disparity demonstrates the ineffectiveness of mammography at decreasing mortality in women at higher risk of late stage diagnosis. In this paper I argue that the continued support of the predominating idea that the benefits of mammograms strictly outweigh their negative effects may be a factor in the continued racial disparity in breast cancer mortality between African-American and Caucasian women. In addition, I will argue that mammograms are less effective for African American women because they are predisposed to later stage diagnosis and the accompanying poorer mortality prognosis due to higher-risk environments caused by varied socio-political status. My claims are supported by studies of incidence rates, survivorship versus mortality rates, screening usage rates, late stage and early stage diagnosis rate, tumor type, and the effects of socioeconomic status on stage of diagnosis. In particular, mortality rates have not decreased parallel with increased mammogram usage, especially in African-American women. Although early stage diagnosis has drastically increased, late stage-diagnosis remains unchanged and higher in African-American women. Tumor types vary by race, and African American women tend to have tumors that are highly prolific and more likely to be metastatic. Socioeconomic factors are more of a marker for breast cancer disparities than race, however race and socio-political structures that embody racism are often intersected.

Since the 1960's, the sport of American football has maintained its stranglehold as the most popular sport in the United States. Both in viewership and participation, football has a massive lead on all other sports, but as of late many factors have led some to believe that trouble could be on the horizon. With various issues including head injuries, player protests, and television viewership decline plaguing football and its professional league, the NFL, the door could be open for another collision sport from across the pond to surge in popularity: rugby. Played in 119 countries by millions of people, rugby is currently one of the most popular sports in the world, but because of American football's dominance in the U.S. it has yet to really find its footing here; however, despite its popularity paling in comparison to football, rugby is actually the single fastest-growing sport in the U.S. Both sports share some strong similarities, and with football facing a myriad of issues, there is real reason to believe that rugby could be on the rise while football could continue to falter. By reading through articles and statistics on the subject, this thesis was divided into four main analysis topics to compare and contrast the two sports: injury problems and how they affect viewership and participation, international following for each respective sport, culture around the games themselves and how it could appeal to American viewers, and potential for growth domestically. By examining these factors within both sports, I was able to come to the conclusion that rugby's potential to take hold in the U.S. is growing, and in the coming years as American football's safety and importance continue to be called into question, rugby could one day even supplant football as the most popular collision sport in the country.

Description
There are many parallels between human and equine sports medicine, including the roots of athletics, the development of specialized medicine, and injuries to the athletes. The most remarkable similarities are seen in tendinopathies. Because of the similarities between human and equine tendons, equine athletes serve as one of the best animal models to study tendon physiology and tendon injuries for application to human medicine. Because of this, many therapies have already successfully crossed from one realm of sports medicine to the other, the most notable of which are stem cell therapy, Interleukin-1 Receptor Antagonist (IRAP), and platelet rich plasma (PRP) therapies. There are also several therapies on the horizon that are very promising to potentially be successful in both human and equine athletes. However, some of these novel therapies are raising ethical questions. There are many regulations in place to protect against or address potential ethical conflicts in human medicine. The same trend is not seen in equine medicine. While there are rules enforced by many equestrian federations regarding ethical concerns and veterinary medicine, the information is not nearly as complete as it should be. Because they lack the autonomy that typical human patient possesses, equine athletes require significantly more advocacy from their veterinarians than human athletes do from their physicians. Additionally, there is a lack of large animal model studies secondary to cost and overall value of equine athletes to their owners, riders, and trainers. Ultimately it becomes an issue of veterinary ethics whether to pursue a novel or conventional treatment for an equine athlete. With biotechnology advancing as quickly as it is, new studies must be done and new regulations must be written in order to keep all fields of sports medicine operating safely and ethically for all athletes involved, regardless of species.

Description
Although it has recently been demonstrated that source monitoring (SM) processes may mediate the relationship between working memory (WM) and false memories, little research has investigated whether the quality of monitoring processes can account for this reduction. In the current study, participants performed multiple false memory, WM, and SM tasks. Consistent with previous research, SM abilities mediated the relationship between WM and false memories (regardless of whether or not participants were warned of the illusions at encoding). High SM individuals were better able to recall contextual information from study to correctly reject lures, whereas low SM individuals were more likely to rely on the quality of retrieved details to reject lures. These results suggest that individuals low and high in SM abilities rely on qualitatively different monitoring processes to reduce errors, and that individual differences in diagnostic monitoring strategies may account for previous relationships found between WM and false memories.

Description
Ten percent of the global population believed that the world would end on December 21, 2012. But people have believed that the world was going to end before. What causes these apocalyptic crazes and what allows them to spread beyond the fringes of society? What role does popular religion play in creating or spreading apocalyptic hysteria? How do these prophets of doom react when the world still exists past its predicted date of expiration? What about the people who believed them? This paper examines historical instances of apocalyptic predictions, how these predictions were formed out of or shaped by popular religion, as well as the reactions \u2014 both internal and external \u2014 of those who either predicted or believed that the end was near. After building this historical context, I turn my focus to the pop culture phenomenon that is the end of the Mayan Calendar. I attempt to understand and explain what aspects of the current social, religious, and psychological climate have contributed to the cultural ubiquity of and fascination with the December 21, 2012 apocalypse, and what the date actually meant to the Classical Maya. Finally, I examine the existential, religious, and cultural factors that make Americans in particular so ready and willing to believe that the end of the earth is imminent.

Description
This study examined the relation between Religiosity (a motivational system) and Working Memory Capacity (a cognitive system) to determine how they interact to promote goal-directed behavior. Participants completed a religiosity questionnaire and engaged in a battery of tasks that were used to assess their Working Memory Capacity (WMC) and overall ability to maintain goal-directed behavior. The Stroop task was used to examine the participants' ability to maintain goals in the face of interference. It was predicted that religiosity and WMC would be inversely related and that when we controlled for religiosity, WMC would be the only significant predictor of Stroop performance. Furthermore, we hypothesized that religiosity and Stoop would be inversely related, whereas WMC and Stroop would be positively correlated with one another. Religiosity and Stroop performance were each divided into three different components. Religiosity was divided into: Intrinsic Motivation, Extrinsic Motivation, and CARMA. Stroop Performance was measured through Stroop Accuracy, the Stroop Effect, and Post-Error Slowing. The results of our study supported each of our hypotheses. These findings demonstrated that there is a cognitive process underlying motivational systems, such as religion, which affect an individual's ability to sustain goal-directed behavior.

Description
Vaccine opposition is a growing problem in developed countries where dropping vaccination rates threaten general public health by laying the foundation for resurgence and reemergence of previously eradicated infectious diseases. This thesis argues that the current movement is only the most recent incarnation of opposition that has co-evolved with vaccine practices for the duration of their mutual histories. Part one provides a historical context for the current movement using the example of the development and deployment of the smallpox vaccine as a representative timeline of vaccine acceptance and opposition. Part two describes the current movement in the United States and the United Kingdom, interprets the reasons for the conclusions drawn by vaccine-concerned parents, and provides a framework for public health officials to approach the issues.
