All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pseudoephedrine is an over-the-counter drug commonly used as a decongestant, but also thought to have ergogenic effects. The World Anti-Doping Agency (WADA) has prohibited large doses (> 150 μg∙ml^-1) of pseudoephedrine, while the National College Athletic Association (NCAA) does not include it on the banned substance list. The purpose of this study was to examine the effect of body weight dosing of pseudoephedrine on 800-m run times of NCAA female runners. Fifteen NCAA female track runners volunteered to participate in the randomized, double blind, crossover design. In trials that were a week apart, participants were given both 2.5 …

Does Non-Steroidal Anti-Inflammatory Drug (Nsaid) Use Affect Dementia Progression And Survival Rates In Alzheimer's Disease? The Cache County Study, Trevor R. Buckley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alzheimer's disease (AD) has multiple factors that contribute to the disease process. Among these is a state of chronic inflammation that is endured by the brain during the aging process. The use of non-steroidal anti-inflammatory drugs (NSAIDs) decreases the amount of neuroinflammation sustained by the brain, and greater levels of NSAID use have been demonstrated to be associated with decreased probability of developing AD. This study looked at whether greater rates of NSAID use were also associated with decreased rates of cognitive and funtional decline and survival in a population-based sample of persons with AD. Linear mixed models failed to …

The Effects Of 24r, 25-Dihydroxyvitamin D3 And 24s, 25-Dihydroxyvitamin D3 On Phosphate Transport In Vivo, Yu Meng

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research studied the effects of the two isomers of 24,25(OH)₂D₃ on phosphate absorption in vivo to increase our understanding of the effects of 24,25(OH)₂D₃ on phosphate transport in vivo, and its two isomers. The current work demonstrates that 24R,25(OH)₂D₃ is capable of decreasing phosphate absorption after a 1h injection in vivo and 24S,25(OH)₂D₃ can increase phosphate absorption after a 5h injection, but this stimulation disappears at time points after 5h.

Since 24,25(OH)₂D₃ is made in vitamin D-replete animals, the observation that 24R,25(OH)₂D …

Acute Effects Of Advocare Spark® Energy Drink On Repeated Sprint Performance And Anaerobic Power In Ncaa Division I Football Players, Nnamdi I. Gwacham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sports drinks, such as Gatorade and Powerade, have been designed to refuel athletes during and after their performance. Specifically they are designed to have optimal levels of carbohydrates to replenish electrolytes and prevent dehydration. In contrast, energy drinks are reported to increase mental alertness and physical performance during exercise. These drinks are designed to have substantial levels of caffeine as the main ingredient. For some years, energy drinks have become widespread both in recreational and trained athletes, because of their presumed influence on physical performance. A variety of energy drinks are currently on the market today and are purported to …

Sexual And Religious Identity Development Among Adolescent And Emerging Adult Sexual Minorities, Angie L. Dahl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As the majority of Americans identify with a religious affiliation, the religious context is an important backdrop upon which identity development occurs. For lesbian, gay, bisexual, transgender, queer, questioning, and allied (LGBTQA) youths, the process of development may be complicated in a religious context due to denominational positions on same-sex sexuality. While recent researchers highlighted the importance of contextual influences on LGBTQA developmental processes, few studies have examined LGBTQA sexual and religious identity development. The goal of the current study was to gain a better understanding and appreciation of LGBTQA adolescent and young adult experiences of religious and sexual identity …

Acceptance And Commitment Therapy For The Treatment Of Compulsive Pornography Use: A Randomized Clinical Trial, Jesse M. Crosby

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Compulsive pornography use (CPU) is generally defined by the inability to control the use of pornography and the resulting negative effects on quality of life or general functioning including damaged relationships, loss of productivity, impaired performance at work or school, job loss, financial expenses, guilt/shame, and personal distress. Statistics indicate that CPU may be as common as other psychological disorders and that the effects of the behavior can be just as severe. It is estimated that 1.5% to 3% of the adult population of the United States meets the criteria for compulsive pornography use. A review of the literature found …

The Effects Of Self-Efficacy On Lower Body Power, Justin E. Jackson

The purpose of this study was to examine the effects of increased self-efficacy on three separate jump tests. Forty-seven students (18 females & 29 males) from Utah State University were randomly assigned to a treatment or control group. Participants performed a vertical jump test, a standing broad jump test, and a 30-s Bosco test on three separate days over a span of 1 week. The treatment group (n = 24) were given false, positive feedback about their performance while the control group (n = 23) were told their true results. Self-efficacy was measured pre and post using the …

Prize-Based Contingency Management: A Vehicle Miles Of Travel Reduction Intervention, Joshua D. Marquit

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During the past 50 years, air pollution has become a growing problem throughout the Intermountain West because of increases in personal vehicle ownership and usage. Scientists continue to design interventions to improve air quality by encouraging people to reduce their personal vehicle miles of travel (VMT). However, results of these interventions have only seen modest reductions in VMT because of some methodological and measurement issues. To address these limitations, a 14-week driving reduction intervention was conducted in Cache County, Utah. This intervention employed a prizebased contingency management system within a single-subject, A-B-A withdrawal research design that rewarded participants with prizes …

Effects Of The Frontier Environment On Identity Development Among First Generation College Students, Kenli Ann Urruty

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The unique experience of first generation college students from frontier communities as they transition to college has not yet been explored in the literature. The current study was designed to explore those experiences and the ways the frontier context and first generation status shape identity development once these youth have left their families and home communities and made the transition to college. To gain a rich understanding of the experiences of first generation college students from frontier communities, this study employed a phenomenological qualitative design and the findings were interpreted through a social constructionist lens. Eleven emerging adults were recruited …

The Impact Of Study Skills Courses On Academic Self-Efficacy In College Students, Brenna M. Wernersbach

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Colleges across the nation are increasingly interested in improving retention of students. Many universities have begun offering workshops and courses targeted at improving study skills in academically underprepared students with the goal of helping students succeed in higher education and continue enrollment. The impact of such courses on study skills themselves has been supported, but prior research has not examined the courses impact on students' beliefs about their ability to succeed in college–that is, their levels of academic self-efficacy. This study examined pre- and post-test levels of academic self-efficacy in college students enrolled in a study skills course in comparison …
