Trauma-Based Priming And Attentional Bias To Smoking Cues: A Stroop Task Study, Pattie B. Sherman

USF Tampa Graduate Theses and Dissertations

Past research has highlighted the importance of better understanding the high rate of smoking among individuals exposed to trauma. However, few studies have investigated the cognitive mechanisms that may contribute to the smoking-trauma relationship. The primary goal of the present study was to examine the associative relationship between smoking and trauma at a cognitive level, by examining the extent to which trauma-relevant pictures primed attentional biases to smoking-related words on a modified Stroop task. Eighty trauma-exposed smokers (classified as having low, medium, or high levels of post trauma symptomatology) ink-named smoking-related and neutral words after being primed with trauma-related, positive, …

Two Essays On Venture Capital: What Drives The Underpricing Of Venture Capitalbacked Ipos And Do Venture Capitalists Provide Anything More Than Money?, Donald Flagg

USF Tampa Graduate Theses and Dissertations

This dissertation includes two chapters that investigate the role venture capitalists (VCs) play in the underpricing and in the long-run performance of IPOs. The first chapter focuses on the underpricing of IPOs and attempts to determine the role that VCs play in this underpricing process. The evidence is consistent with a view that VCs agree to underpricing to ascertain benefits from both "grandstanding" and "spinning." The second chapter examines the long-run performance of IPOs and tries to determine the role that VCs play in the development of IPOs. Here, the evidence suggests that VC-backed IPOs appear to have better access …

Application And Refinement Of The Karst Disturbance Index In West Central, Florida, Leslie A. North

USF Tampa Graduate Theses and Dissertations

A hierarchical and standardized environmental disturbance index, specifically designed for karst landscapes, was created by van Beynen and Townsend (2005). To assess the applicability of the index and provide recommendations for its refinement, the index was applied in four west-central Florida counties and interviews were conducted with local and state officials, community planners, and land resource managers. The karst disturbance index consists of 30 indicators contained within five broad categories: geomorphology, hydrology, atmosphere, biota, and culture. Data was readily available for most environmental indicators used to construct the index. Overall, levels of disturbance vary between the counties due to the …

Structural Equation Model Of Exercise In Women Utilizing The Theory Of Unpleasant Symptoms And Social Cognitive Variables, Sarah Elizabeth Cobb

USF Tampa Graduate Theses and Dissertations

A dramatic decline in physical activity levels occurs from adolescence to young adulthood. Those who were sedentary as adolescents tend to maintain a sedentary lifestyle. Women are particularly vulnerable to the effects of a sedentary lifestyle because of the risk for cardiovascular disease. The purpose of this research was to test a theoretical model of exercise in adolescent and young adult women using the theory of unpleasant symptoms with social cognitive variables and then to test a revised model that was determined a priori. The central hypotheses were that the relationships as depicted in the proposed theoretical models would be …

Three Theories Of Individualism, Philip Schuyler Bishop

USF Tampa Graduate Theses and Dissertations

This thesis traces versions of the theory of individualism by three major theorists, John Locke, John Stuart Mill and John Dewey, as they criticize existing social, cultural, economic, legal and military conditions of their times. I argue that each theorist modifies the theory of individualism to best suit their understanding of human nature, adapting it where they can and outright removing aspects where they cannot. Based upon each thinker's conception of human nature, their corresponding theory of individualism does justice to that nature. With their view of individualism, each thinker criticizes the activities of their day for its lack of …

The Pragmatist And The Aesthete: Late Nineteenth-Century Religion And Theology In Harold Frederic’S The Damnation Of Theron Ware And Ellen Glasgow’S Phases Of An Inferior Planet, Matthew Antonio

USF Tampa Graduate Theses and Dissertations

A comparison between Ware, Forbes, and Soulsby from The Damnation of Theron Ware provides a glimpse into one aspect of the theological upheaval of the time. A comparison between Ware, Forbes, and Algarcife, from Phases of an Inferior Planet, however, hearkens forward to the alienation and questioning of identity so much a part of the Twentieth Century. By viewing Ware as a foil for Forbes and Soulsby in tandem with Algarcife, a more complete picture of the transition between nineteenth and twentieth-century religion and theology may be found.

Understanding the encounter between the traditional and the liberal clergy requires …

The Right To Health: Conflicting Paradigms Of Health As Commodity Vs. Health As Human Right, Robert Colin Nelson

USF Tampa Graduate Theses and Dissertations

Despite the fact that the United States spends more per capita than any other nation on healthcare for its citizens, the quality of American health outcomes lags well behind every other developed country in the world. This paper proposes that it is no coincidence that the United States is also the only developed nation that does not guarantee the right comprehensive coverage of medical services for its citizens. Instead, we rely on a fee-for-service system which functionally denies quality health care to those without the means to pay for it. In this paper I document the experiences of various clients …

Socio-Natural Landscapes In The Palmarejo Valley, Honduras, James R. Hawken

USF Tampa Graduate Theses and Dissertations

Communities have traditionally been viewed as spatially bounded social units composed of multiple households whose inhabitants are integrated by shared resources and a common sense of identity. While investigating resources and identity is useful for archaeological study because of their material correlates, such views of community ultimately fail to acknowledge the dynamic interaction between cultural and environmental forces in shaping and shifting those arrangements over time. This study examines settlement, excavation, and geoarchaeological data from the Palmarejo Valley in northwestern Honduras with the aim of modeling the process of community formation at the intersection of social and natural landscapes in …

Re-Thinking The Myth Of Perugino And The Umbrian School: A Closer Look At The Master Of The Greenville's Jonas Nativity Panel, Carrie Denise Baker

USF Tampa Graduate Theses and Dissertations

In 1959, Federico Zeri isolated an Umbrian painter and named him the Master of the Greenville after the Madonna and Child with Angels tondo in Greenville, South Carolina. Through connoisseurship, scholars have since attributed over thirty-two works to the Master of the Greenville, categorizing the anonymous artist as a close follower of Perugino's style.

My research focuses on a Nativity panel now in the Museum of Fine Arts in Saint Petersburg, Florida. It is called the Jonas Nativity after its former owner, the late art collector Harriet H. Jonas. Through connoisseurship, scholars have almost exclusively focused on attributing the Jonas …

Climatic And Structural Controls On The Geomorphology Of Wadi Sana, Highland Southern Yemen, Joshua Michael Anderson

USF Tampa Graduate Theses and Dissertations

Middle Holocene climate change forced significant environmental response and influenced human activities throughout southern Arabia. Climate models and proxy data indicate that climate along the southern Arabian peninsula changed from a moist phase, spanning the early to middle Holocene, to an arid phase, which persisted for the last ca. 5,000 years. A weakening and southward shift of the Southwest Indian Monsoon System, forced by northern hemisphere insolation variations in the precession band and/or glacial boundary conditions, is suggested as the mechanism for the abrupt shift to more arid conditions. Geoarchaeological evidence suggests that agriculture was more widespread and evolved alongside …

The Effect Of Doing Good: An Experimental Analysis Of The Influence Of Corporate Social Responsibility Initiatives On Beliefs, Attitudes, And Behavioral Intentions, Cristina Marta Gonzalez

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to further current theory-driven research in public relations by examining the influence of corporate social responsibility (CSR) initiatives on beliefs, attitudes, and behavioral intentions. Specifically, CSR initiatives identified by Kotler and Lee (2005) were tested using Fishbein and Ajzen’s (1975, 2005) theory of reasoned action to determine their influences on individual’s belief, attitudes, and behavioral intentions toward an organization and its products. This area of inquiry is particularly relevant for public relations scholars and practitioners since creating awareness of CSR practices among key stakeholders requires accurate and timely communication.

A controlled experiment utilizing a …

Learning On Complex Simulations, Robert E. Banfield

USF Tampa Graduate Theses and Dissertations

This dissertation explores Machine Learning in the context of computationally intensive simulations. Complex simulations such as those performed at Sandia National Laboratories for the Advanced Strategic Computing program may contain multiple terabytes of data. The amount of data is so large that it is computationally infeasible to transfer between nodes on a supercomputer. In order to create the simulation, data is distributed spatially. For example, if this dissertation was to be broken apart spatially, the binding might be one partition, the first fifty pages another partition, the top three inches of every remaining page another partition, and the remainder confined …

Structure-Function Studies Of Conserved Sequence Motifs Of Cytochrome B5 Reductase:, Louis J. Crowley

USF Tampa Graduate Theses and Dissertations

NADH:Cytochrome b₅ Reductase (cb₅r) catalyzes the two electron reduction of the iron center of the heme cofactor found within cytochrome b₅ (cb₅) utilizing reducing equivalents of the nicotinamide adenine dinucleotide (NADH) coenzyme. Cb₅r is characterized by two domains necessary for proper enzyme function: a flavin-binding domain and a pyridine nucleotide-binding domain. Within these domains are highly conserved "motifs" necessary for the proper binding and orientation of both the NADH coenzyme and the FAD cofactor.

To address the importance of these conserved motifs site-directed mutagenesis was utilized to generate a …

The Association Between Risk Taking And Personality, Gabriella Anic

USF Tampa Graduate Theses and Dissertations

The aim of this study was to examine the association between personality and risk taking in a sample of 461 older adults from the Charlotte County Healthy Aging Study (CCHAS). The personality factors of openness to experience, extraversion, neuroticism, agreeableness and conscientiousness were measured with the NEO Five Factor Inventory. Risk-taking was measured with an 8-item questionnaire and a single-item question that assessed subjects' participation in sensation seeking behaviors. Spearman correlation coefficients, hierarchical linear regression and hierarchical logistic regression were used to assess the association. As consistent with past research, high scores on openness to experience (beta = 0.16, P<.0001) and low scores on neuroticism (β = -0.14, P<.01) and agreeableness (β = -0.16, P<.01) were associated with the total score of the 8-item risk taking questionnaire. The single-item risk question was also associated with openness [OR = 1.09; 95% CI: 1.05-1.13], neuroticism [OR = 0.94; 95% CI: 0.90-0.97] and agreeableness [OR = 0.95; 95% CI: 0.92-0.99]. After stratifying by gender, only openness was still significantly associated with risk-taking. Interaction terms including gender and personality factors were added to the models to test if gender was an effect modifier. Although personality differences existed between men and women, none of the interaction terms were statistically significant.

Growth Factor-Mediated Telomerase Activity In Ovarian Cancer Cells, Yira Bermudez

USF Tampa Graduate Theses and Dissertations

Ovarian cancer is the leading cause of gynecological cancer death in the United States. Even though no single genetic alteration can be attributed to all ovarian cancers, 90% of ovarian tumors express telomerase, a ribonucleoprotein that elongates telomeric (TTAGGG)n repeats de novo. In normal somatic cells, telomerase is absent. In cancer cells, the re-expression of telomerase allows senescence to be bypassed contributing to cellular immortalization, a key step for cellular transformation, making telomerase a potentially important target for therapeutic intervention.

Ovarian cancer cells secrete vascular endothelial growth factor (VEGF) and lysophosphatidic acid (LPA) that feedback through their receptors present …

Reality Cosmetic Surgery Makeovers: Potential Psychological And Behavioral Correlates, Steffanie Sperry

USF Tampa Graduate Theses and Dissertations

According to the American Society of Plastic Surgeons (2006), the number of cosmetic procedures has increased to over 10 million in 2005, showing a 38% increase from 2000. This increase in cosmetic surgery prevalence is paralleled by a surge in reality cosmetic makeover television programming, such as Extreme Makeover and Dr. 90210. No research to date has assessed the potential relationships between reality media viewership and body image, eating pathology, or cosmetic surgery attitudes. The tripartite model of core influence (Thompson et al., 1999) is presented as a theoretical framework for conceptualizing the link between media influences, internalization, body image …

Novel Polymer-Metal Nanocomposites For Applications In Detection And Sensing, Dayling L. Chaparro

USF Tampa Graduate Theses and Dissertations

Detection of trace elements such as organic contaminants, explosive residues, and metal ions is an intellectually challenging task in science and engineering. It is also a topic of increasing importance due to its impact on society and the environment. Designing molecularly imprinted materials is one of the most promising approaches to explore sensing and detection applications. “Stimuli-sensitive” polymer materials are ideal candidates for these imprinted sensors as they are able to respond to changes in their environment and can be tailored by cross-linking the polymer chains. The responses can be amplified and transduced into measurable signals due to macromolecular properties …

Symbolic Computations Of Exact Solutions To Nonlinear Integrable Di®Erential Equations, Vladimir Grupcev

USF Tampa Graduate Theses and Dissertations

In this thesis, first the tanh method, a method for obtaining exact traveling wave solutions to nonlinear differential equations, is introduced and described. Then the method is applied to two classes of Nonlinear Partial Differential Equations. The first one is a system of two (1 + 1)-dimensional nonlinear Korteweg-de Vries (KdV) type equations. The second one is a (3 + 1)-dimensional nonlinear wave equation. At the end, a few graphic representations of the obtained solitary wave solutions are provided, in correspondence to different values of the parameters used in the equations.

Evanescent Field Absorption Sensing Using Sapphire Fibers, Michael Grossman

USF Tampa Graduate Theses and Dissertations

This thesis explores the application of coiled sapphire multimode optical fibers for evanescent wave chemical sensing in both the visible spectrum and the near infrared. As has been suggested in the literature pertaining to silica fibers, bending converts low-order modes to high order ones, which leads to more evanescent absorption and thus a more sensitive chemical detector. By coiling the fiber many times, it was expected that even greater sensitivity would be attained.

Experiments were performed to investigate the sensor response to different solutions and to characterize this response. In the first of three experiments, the large absorption peak of …

Shakespearean Spin-Offs: Mindless Entertainment Or Conversations With Critics, Amy Anderson

USF Tampa Graduate Theses and Dissertations

Literature is always in a state of evolution. Words change; the way writers write changes. Even actual literary works transform. William Shakespeare manipulated numerous classic works of literature to make extraordinary dramas for both his lifetime and eras since. Much as Shakespeare adapted literature to suit his purposes, writers today are constantly utilizing story lines introduced by the bard over four-hundred years ago in various modern-day mediums. Shakespeare wrote most of his works for the entertainment of the masses; Shakespeare's works are adapted today for both entertainment and academic endeavors. Certainly, a Klingon (Star Trek) version of arguably …

Natural Law Ethics: A Comparison Of The Theravāda And Thomistic Traditions, David Lantigua

USF Tampa Graduate Theses and Dissertations

This thesis investigates the topic of natural law in the Therav

āda and Thomistic traditions by utilizing the methodology of comparative religious ethics. Approaches to the method such as ethical formalism, ethical naturalism, and narrative ethics are assessed with the author opting for a multidimensional approach that is religious and ethical. This multidimensional approach, as defined by William Schweiker, conducts natural law inquiry from a hermeneutical standpoint of moral diversity and democratic pluralism.

The hermeneutical standpoint warrants a historicizing of natural law ethics that is compatible with modern secularity instead of a classicist metaphysical worldview. To achieve this task, the …

The Effects Of Invasive Cogongrass (Imperata Cylindrica) On The Threatened Gopher Tortoise (Gopherus Polyphemus), Katherine A. Basiotis

USF Tampa Graduate Theses and Dissertations

The gopher tortoise (Gopherus polyphemus) is critical to upland communities and considered a keystone species. A recent threat to gopher tortoise habitat is the invasive cogongrass (Imperata cylindrica), which spreads rapidly, eliminating native vegetation. This study consisted of three experiments to investigate the effects of the cogongrass on a population of gopher tortoises. A feeding experiment revealed that individuals readily ate native vegetation, but would not eat cogongrass. A tracking experiment showed that there was a significantly different mean angle of movement between individuals whose home ranges were outside cogongrass compared to those that overlapped cogongrass, …
