Thyroid Hormone Regulation Of Cholesterol Metabolism, Lindsey R. Boone

USF Tampa Graduate Theses and Dissertations

In this study, we examined the effects of thyroid hormone on regulatory processes of cholesterol metabolism. Specifically, the pathways of cholesterol synthesis and cholesterol efflux were investigated. Hepatic HMG-CoA reductase (HMGR) is the rate-limiting enzyme in cholesterol synthesis. Hypothyroid rats exhibit decreased expression of this gene, which can be induced by subsequent treatment with thyroid hormone. The mechanism of this activation was previously unknown. Utilizing in vivo electroporation, we identified HMGR promoter elements necessary for the induction of HMGR by thyroid hormone. The -316/-321 element, the sterol response element, and nuclear factor-y site were all found to be necessary to …

Identification And Characterization Of Mitochondrial Genome Concatemers In Aids-Associated Lymphomas And Lymphoma Cell Lines, Felipe Bedoya

USF Tampa Graduate Theses and Dissertations

Despite recent advances in the understanding of the molecular bases of hematological malignancies, the specific mechanisms on how they originate and why some subtypes are more prevalent than others still remain to be elucidated. These two important aspects have been even more difficult to analyze when dealing with individuals under immune suppression because other factors must be considered. Questions still remain as to why individuals with AIDS tend to develop lymphoproliferative disorders differently from those observed in individuals under iatrogenic immunosuppressive therapy. Most of lymphomas occurring in transplant recipients are B-cell neoplasias typically associated with Epstein-Barr virus (EBV) infection. In …

This theoretical framework …

Evaluating The Effects Of Exergaming On Physical Activity Among Inactive Children In A Physical Education Classroom, Victoria A. Fogel

USF Tampa Graduate Theses and Dissertations

Childhood obesity is a serious concern that requires the attention of the behavioral community. The U.S. Department of Health and Human Services (2007) recommends that children engage in physical activity for 60 minutes per day. Children spend the majority of their day in school, making school an ideal environment to increase the opportunity for physical activity. Simple, straightforward interventions that can be applied in the school setting, which take into consideration the environment and focus on maintenance by making the process of engaging in physical activity reinforcing, are greatly needed. Video games have been noted in the literature as a …

Evaluation Of A Level System With A Built In Token Economy To Decrease Inappropriate Behaviors Of Individuals With Mental Retardation, Ashley Tomaka

USF Tampa Graduate Theses and Dissertations

The level system is a behavioral procedure that alters the status of a participant contingent on his or her behaviors; within each level the amount of reinforcement is different. In most cases, level systems are paired with another form of treatment such as a token economy. In the current study, the effectiveness of a level system with a built in token economy was evaluated within three intensive residential group homes with 3 male participants. Each participant was diagnosed with mental retardation and behavioral issues. The level system was comprised of 5 different levels, each having different privileges and reinforcers. Each …

A Greener Vertical Habitat: Creating A Naturally Cohesive Sense Of Community In A Vertical Multi-Family Housing Structure, Justin Onorati

USF Tampa Graduate Theses and Dissertations

Throughout multiple dense, tropical, urban contexts, high rise residential environments have created a sense of social detachment, where public and private green spaces do not often exist. It is through these varieties of green spaces that social interaction is encouraged, and without these social activities taking place, this vertical community becomes almost a meaningless entity within the urban realm. The issue being addressed within this thesis is the scarcity of public and private green spaces within our high density tropical urban fabrics that help to create a sense of community. The majority of dense urban settings that we inhabit today …

Green Local Governments In Florida: An Analysis Of Sustainability And Green Building Policies, Naimish S. Upadhyay

USF Tampa Graduate Theses and Dissertations

Sustainable development is increasingly being integrated within local government planning across United States. Many communities are attempting to translate this general principle into specific and measurable terms. The urban sustainability planning literature has mostly focused on descriptive case studies of pioneering cities that have been characterized as true innovators in their sustainability efforts. Noticeably absent from the literature, however, has been an examination of the sustainable development claims made by local governments undergoing 'green' certifications. This study evaluates the commitment and efforts of municipalities and counties of Florida within the framework of Florida Green Building Coalition's 'Green …

Barriers And Facilitating Factors To High School Students’ School Engagement, Amy Green

USF Tampa Graduate Theses and Dissertations

Students who are engaged in their high school environment have higher graduation rates, fewer discipline problems, and lower delinquency rates. In addition, students who are connected to teachers and involved in extracurricular activities consistently experience positive outcomes. However, although the benefits of school resources such as extra-curricular activities and connections to supportive individuals during high school have been well documented, the factors influencing utilization of these resources have not yet been established. Given the known benefits of activity participation and connection to supportive individuals in school settings, and the voluntary nature of their utilization, it is important to investigate factors …

The Influence Of Daily Social Stimulation In Ameliorating Ptsd-Like Behavioral And Physiological Changes In Rats Exposed To Chronic Psychosocial Stress, Shyam Seetharaman

USF Tampa Graduate Theses and Dissertations

Individuals exposed to life-threatening trauma are at increased risk for developing post-traumatic stress disorder (PTSD). Not all people exposed to trauma, however, go on to develop PTSD. Some evidence suggests that individuals who receive social stimulation, such being involved in supportive social networks, are less likely to develop PTSD compared to those lacking social interactions. Although human research has been effective in demonstrating associations between higher levels of social stimulation and lower incidences of PTSD, there has been a lack of experimental evidence suggesting that social stimulation protects against the onset of the disorder after trauma. Here, we tested the …

An Empirical Analysis Of Public Perception Of Reclaimed Water Applying The Situational Theory Of Publics, Jessica Voss

USF Tampa Graduate Theses and Dissertations

Utilizing J.E. Grunig's (1989a, 1997) situational theory of publics and Fishbein and Ajzen's (1975) theory of reasoned action, this empirical study examined the public's perception of reclaimed water. Specifically, the three independent variables - problem recognition, constraint recognition, and level of involvement - were separated into internal and external variables to determine their influences on behavioral intention. The independent variables were also used to determine the public's communication behavioral intention.

The findings of this study support the basic premise of the situational theory of publics and contribute to the extension of the theory through the inclusion of some of the …

USF Tampa Graduate Theses and Dissertations

Binge eating is a maladaptive eating practice associated with unhealthy weight control methods (vomiting, laxative abuse) and the development of weight gain and obesity. Isolating psychological and environmental variables that trigger binge eating can prevent or potentially moderate eating disturbance. Previous research implicates media exposure as an environmental contributor to psychological and eating disturbance. The current study sought to uncover whether fat stigmatization media exposure is an acute environmental trigger for psychological disturbance and binge initiation by dismantling fat media messages and experimentally manipulating messages. Undergraduate women (N=197) were assigned to one of four media message conditions: a fat negative …

Perceptions Of Weight Status: The Effects Of Target Features (Fat/Muscularity Level, Gender, Ethnicity) And Rater Features (Ethnicity And Gender), Tovah Yanover

USF Tampa Graduate Theses and Dissertations

Previous research has explored self-perception of weight and has established that women tend to overestimate their own weight while men tend to underestimate. New research has also begun to examine parental perceptions of their children's weight and has indicated that parents tend to be fairly inaccurate, particularly when it comes to recognizing overweight in their own children. No research has focused on the way in which we perceive the weight of the many other individuals we encounter on a daily basis. The present study was designed to investigate the way in which the weight of others is rated and the …

Air Toxics And Equity: A Geographic Analysis Of Environmental Health Risks In Florida, Angela Gilbert

USF Tampa Graduate Theses and Dissertations

A large number of quantitative studies have examined social inequities in the geographic distribution of air pollution. Although previous research has made strides towards understanding the nature and extent of inequities, they have been limited methodologically in three ways. First, the presence of pollutants have been rarely linked to their adverse health effects, with many studies using proximity to sources as a proxy for risk. Second, there has been a tendency to study a single pollution source instead of assessing multiple types of sources. Finally, conventional statistical methods such as multivariate regression have been limited by their inability to discern …

One Season In An Other’S: Examining Teacher Preparation In Cultural Relevance Literacy Through Intentional And Focused Teaching Case Use, Coleen E. Sams

USF Tampa Graduate Theses and Dissertations

Teacher educators need to develop better teaching methods in order to, ultimately, serve future students in classrooms that are increasing in diversity. It is vital that education majors do more than hear and read about social justice issues facing their prospective students; for them to both understand it and retain it, they need deeper interaction with the issues and alternative strategies for resolving them. This model for using teaching cases may enable teacher educators to demonstrate the relevance of their coursework to their midlevel education students, ultimately enhancing learning gains.

Of equal importance to their professional development, prospective teachers need …

Praxis And Theōria: Heidegger’S “Violent” Interpretation, Megan E. Altman

USF Tampa Graduate Theses and Dissertations

This paper attempts to mark out new ground in the connections between the philosophical writings of Martin Heidegger and Aristotle by posing an interesting question that has never been addressed. Both writers devote much of their early thoughts to questions concerning human beings' practical ways of understanding. However, in their later thoughts Heidegger and Aristotle suddenly seem to completely change the subject to ideal or transcendental ways of understanding. At first glance these ideal modes of human apprehension seem to have nothing to do with each other. Yet, Heidegger and Aristotle seem to have similar motives for turning away from …
