First-Principles Studies Of Shock-Induced Phenomena In Energetic Materials, Aaron Christopher Landerville

USF Tampa Graduate Theses and Dissertations

An understanding of the atomic-scale features of chemical and physical processes taking place behind the shockwave front will help in addressing some of the major challenges in energetic materials research. The high pressure shockwave environment can be simulated using computational techniques to predict mechanical and chemical properties of a shocked material. Density functional theory calculations were performed to investigate uniaxial compressions of diamond and both hydrostatic and uniaxial compressions of TATB and NEST-1. For diamond, we calculated shear stresses for uniaxial compressions in the , , and directions and discovered the anomalous elastic regime which is responsible for the significant …

Intervention In Painting By Marlene Dumas With Titles Of Engagement: Ryman's Brides, Reinhardt's Daughter And Stern, Susan King Klinkenberg

USF Tampa Graduate Theses and Dissertations

Marlene Dumas is known for her portraits and figurative paintings and drawings. This study focuses on three paintings by Dumas that reference male icons of art: Stern (2004), Ryman's Brides (1997), and Reinhardt's Daughter (1994). In referencing Ad Reinhardt, Robert Ryman and in the case of Stern, Gerhard Richter, Dumas engages with each artist and the history of painting in specific ways. As this thesis title indicates, I argue that Dumas uses artistic allusion pervasively throughout her oeuvre to conduct an intervention in painting. I propose that this interposition is a way to navigate and question the canon, while strengthening …

“You‟Re Going To Hollywood!”: Gender And Race Surveillance And Accountability In American Idol Contestant‟S Performances, Amanda Leblanc

USF Tampa Graduate Theses and Dissertations

This paper examines how the reality competition television program American Idol serves to reinforce gendered, racialized and heteronormative stereotypes, particularly for female contestants. Through its "democratic" style of public audience voting, those competitors who not only sing well, but also perform their gender and race to standards which have been deemed by the judges to be appropriate mainstream American culture, prove to be the most successful on the program. Through a content analysis of the show's first four seasons, I find that those female contestants who begin their tenure in the contest by fitting into categories which would be considered …

The Spectrum Of Self-Harm In College Undergraduates: The Intersection Of Maladaptive Coping And Emotion Dysregulation, Christa D. Labouliere

USF Tampa Graduate Theses and Dissertations

Suicidality and non-suicidal self-injury are highly prevalent on college campuses and death by suicide is the number two cause of death for that age demographic. Even with such a deadly public health concern, little is known about how self-harm behavior can be prevented or effectively treated. Research has suggested that differences in affect regulation may differentiate those who engage in self-harm from those who do not, but many of these studies have examined disparate pieces of affect regulation without addressing the overlap and interaction of regulatory behaviors. The field must discover what specific aspects of affect regulation go awry, if …

Social Network Web Sites And Intra-Organizational Relationships: Using Facebook To Build Employee Relationships At Serena Software, Rianna K. Lee Sing

USF Tampa Graduate Theses and Dissertations

This study explores the use of Facebook as a tool to build relationships at work among employees of global technology company Serena Software. Email interviews with 13 Serena Software employees demonstrated that the social network site is in fact building relationships among them. Participants attributed information sharing as the element that most helped them to build relationships with each other. The interviews revealed evidence of the characteristics of relationship quality: trust, commitment and satisfaction. However, participants expressed a different definition of the fourth characteristic - control mutuality - in their Facebook relationships. The results showed that participants did not define …

Investigation Into The Rate-Determining Step Of Mammalian Heme Biosynthesis: Molecular Recognition And Catalysis In 5-Aminolevulinate Synthase, Thomas Lendrihas

USF Tampa Graduate Theses and Dissertations

The biosynthesis of tetrapyrolles in eukaryotes and the alpha-subclass of purple photosynthetic bacteria is controlled by the pyridoxal 5?-phosphate (PLP)-dependent enzyme, 5-aminolevulinate synthase (ALAS). Aminolevulinate, the universal building block of these macromolecules, is produced together with Coenzyme A (CoA) and carbon dioxide from the condensation of glycine and succinyl-CoA. The three-dimensional structures of Rhodobacter capsulatus ALAS reveal a conserved active site serine that moves to within hydrogen bonding distance of the phenolic oxygen of the PLP cofactor in the closed, substrate-bound enzyme conformation, and simultaneously to within 3-4 angstroms of the thioester sulfur atom of bound succinyl-CoA. To elucidate the …

The Political Ecology Of Intestinal Parasites Among Nicaraguan Immigrants In Monteverde, Costa Rica, Jason D. Lind

USF Tampa Graduate Theses and Dissertations

Over the past 15 years Monteverde, Costa Rica has undergone rapid economic, social, political, and environmental change due to a flourishing ecotourism economy. While the effects of ecotourism development in Monteverde are many, two important consequences have been: 1) the immigration of Nicaraguan nationals to the area seeking low-skilled wage labor; and 2) compromised water resources management due to pollution and rapid population growth. The objective of this research is to investigate and identify the inter-relationships between ecotourism development in Monteverde and its affect on infectious diseases outcomes within the context of immigration and water resources management. Specifically, this dissertation …

Afro-Colombian Welfare: An Application Of Amartya Sen’S Capability Approach Using Multiple Indicators Multiple Causes Modeling – Mimic, Paula Lezama

USF Tampa Graduate Theses and Dissertations

This research analyzes welfare conditions of Afro-Colombians vis-à-vis non Afro-Colombians using Amartya Sen's Capability Approach as the theoretical framework, and the latent variable modeling as the empirical method. Multiple Indicators Multiple Causes (MIMIC) models are estimated using data from the Colombian Quality of Life Survey, 2003. Two latent constructs, namely, 'knowledge' and 'being adequately sheltered', represent the two 'Capability' dimensions to be analyzed. Ethnic background appears to have a consistently negative influence after controlling statistically by a set of relevant variables (e.g. being poor, area, marital status, age and gender, among others) included in the models as exogenous "causes" or …

Initial Identity Level And Cooperation In Face-To-Face And Computer-Mediated Contexts, Matthew C. Lineberry

USF Tampa Graduate Theses and Dissertations

Organizations today are increasingly encouraging employees to engage in pro-social behaviors at work, though this effort may be hindered by the increasing reliance on computers to mediate workplace interpersonal interactions. While much research has been directed at computer-mediated teams performing highly interdependent tasks, there is a need to examine the effect of computer mediation on individual vs. collective identification and cooperation for employees in less overtly interdependent tasks. This study examined the role of group members' conscious and non-conscious identity level in the relationship between physical context and cooperation with a work group. 50 groups of 4 participants each worked …

The Neoconservative War On Modernity: The Bush Doctrine And Its Resistance To Legitimation, Ben Luongo

USF Tampa Graduate Theses and Dissertations

The Bush Doctrine represents a paradigm shift in international security policy. Never had a foreign policy demonstrated such will through unilateralism, preemptive militarism, and a sense of exceptionalism. I argue that this shift in policy resists modern international order in an attempt to reestablish ancient modes of power and control. The international system maintains order through rules and institutions which are perceived to be legitimate because they have the consent of the governed. An example of this would be the UN, where member states engage in a democratic deliberation geared towards reaching understanding and consensus. However, order breaks down when …

This dissertation translates an essay by Mario Untersteiner "Le origini sociali della sofistica" ("The Social Origins of Sophistry") unpublished in English, and explores its significance in terms of classical and contemporary rhetorical theory, as well as the composition classroom. In the process, I attempt to contribute to reestablishing sophistry and rhetoric within our contemporary cultural milieu. More specifically, the dissertation is organized into five main parts: The first chapter offers an introduction to and thorough background of the sophists in ancient and classical Greece; the second chapter reviews the scholarship about the sophists, as well as that on Mario Untersteiner …

Multiple Approaches To The Validation Of The Scores From The Study Anxiety Inventory, George Douglas Lunsford

USF Tampa Graduate Theses and Dissertations

The Study Anxiety Inventory (SAI), consisting of the factors of worry and emotionality, was developed to measure college students' self-reported levels of anxiety while studying for an exam. Data from 2002 undergraduate students from four colleges (Arts and Sciences, Engineering, Business, and Education) at a southeastern state university were used to evaluate the validity of the scores from the 16-item Study Anxiety Inventory. Results of confirmatory factor analyses for the two factor model, conducted separately for each college, indicated marginally acceptable fit for the data (median fit measures across the four colleges: CFI =.915, SRMR=.049, RMSEA=.098), a pattern that was …

From Maiden To Whore And Back Again: A Survey Of Prostitution In The Works Of William Shakespeare, Tiffany Lowden Messerschmidt

USF Tampa Graduate Theses and Dissertations

The works of William Shakespeare reflect the society in which he lived, and they can therefore be studied for the light they shed upon certain aspects of this society that may otherwise have been ignored or misrepresented by other surviving documents. This is especially true of prostitution. Women in this shifting English society were marginalized, and the prostitute occupied an especially precarious place since her profession identified her as an outsider, legally and morally. Surviving historical documents address the legality or morality of this institution, but fail to reveal how it was perceived by society as a whole. Shakespeare receives …

At What Cost? : Spanish Neutrality In The First World War, Carolyn S. Lowry

USF Tampa Graduate Theses and Dissertations

While historians have gone to great efforts in studying the belligerent powers during the First World War, very little attention has been paid to such neutral powers as Spain. Several European nations declared neutrality in 1914, but many strayed from this course in favor of active belligerence. Spain, however, remained neutral for the war's duration; thus, this thesis examines and explores the nature of Spanish neutrality during the First World War. Spain's decision to adhere to a neutral policy required serious consideration as it had to weigh the consequences and advantages of intervention; however, military and economic weakness, as well …

Condition | Recondition: Reconstruction Of The City And Its Collective Memory, C Lopez

USF Tampa Graduate Theses and Dissertations

Worldwide, dense urban spaces have been organized and transformed by cultural values. However, in many cases, changes in economic and social conditions have resulted in fragmentation of neighborhood typologies, in terms of their physical characteristics and uses. Such spaces are a manifestation of development, expansion, dislocation and marginalization; a condition that can be improved through an architectural and urban strategy which inscribes emerging forces into the neglected zones of marginal territories. The contemporary context calls for a re-evaluation of public space. To fully engage the people, it is a necessary function of public space to blur landscape, architecture and infrastructure, …

Maternal Knowledge, Attitudes And Practices And Health Outcomes Of Their Preschool-Age Children In Urban And Rural Karnataka, India, Angela Lloyd

USF Tampa Graduate Theses and Dissertations

This cross-sectional, community-based study was designed to compare the health outcomes of 2 - 5 year-old children in different types of preschools. The Integrated Child Development Services (ICDS), run by the government of India, created a system of preschools, called anganwadis, to combat malnutrition, provide health education for mothers, and preschool for children 2 - 6 years old in 1975. Many children attend their local anganwadis, while others attend private schools, and others do not attend school at all. A pre-tested questionnaire was used to interview 125 urban and 130 rural mothers regarding their knowledge, attitudes, and practices about acute …

Correlates Of Attitudes Toward Behavioral Health Services Among Older Primary Care Patients, Nancy Bridger Lynn

USF Tampa Graduate Theses and Dissertations

Research suggests that more than ten percent of older adults experience behavioral health problems (including mental health problems and/or substance abuse). However, very few actually receive care from a behavioral health care provider or even a primary care provider. One major barrier to accessing and receiving care is the feeling of perceived stigma commonly associated with behavioral health problems. The present study examined the relationships among attitudinal variables, feelings of stigma, and behavioral health outcomes over time in an elderly population with the secondary analysis of data collected for a previously implemented research study, the Primary Care Research in Substance …

Mixture Distributions With Application To Microarray Data Analysis, O'Neil Lynch

USF Tampa Graduate Theses and Dissertations

The main goal in analyzing microarray data is to determine the genes that are differentially expressed across two types of tissue samples or samples obtained under two experimental conditions. In this dissertation we proposed two methods to determine differentially expressed genes. For the penalized normal mixture model (PMMM) to determine genes that are differentially expressed, we penalized both the variance and the mixing proportion parameters simultaneously. The variance parameter was penalized so that the log-likelihood will be bounded, while the mixing proportion parameter was penalized so that its estimates are not on the boundary of its parametric space. The null …

The Babel Paradox, Michel Machado

USF Tampa Graduate Theses and Dissertations

The purpose of the book of Acts is still not well understood. Various interpretations have been offered in order to make sense of the narrative and its author's intention. What is the point of Luke's second book in portraying the evangelization of the Roman Empire as a rabid confrontation between Jewish followers of Jesus and other Jewish people? This matter calls for an examination of the relationship between the mother religion and the Jesus movement as it expands into a universal religion. Luke portrays the Jesus movement as the focus of divine favor, in contradistinction to the Jewish nation which …

Cardiovascular Risk Factors For Mild Cognitive Impairment, Michael Malek-Ahmadi

USF Tampa Graduate Theses and Dissertations

The relationship between cardiovascular conditions and the presence of Alzheimer's disease (AD) has been well-documented in a number of recent studies. Generally, the presence of cardiovascular conditions such as high total cholesterol and hypertension have been shown to significantly increase the risk for the development of AD. Given the results of these studies, it is possible that these same risk factors might also increase the risk of developing mild cognitive impairment (MCI). An analysis of 216 subjects (119 cognitively normal (CN), 77 aMCI, 20 naMCI) found that after adjusting for age, education, ethnicity, and gender, only hemoglobin A1c (HbA1c) showed …

Photography’S Creative Influence On Lewis Carroll’S Alice’S Adventures In Wonderland And Through The Looking Glass And What Alice Found There, Bridget Mahoney

USF Tampa Graduate Theses and Dissertations

Lewis Carroll's novels Alice's Adventures in Wonderland and Through the Looking Glass and What Alice Found There share many characteristics with the author's photographs. Both Carroll's portraits and literature utilize dreamlike imagery to move beyond the present time and space into a dream world. The similar imagery demonstrates an important creative link between Carroll's novels and photographs. The creation of Carroll's masterpiece, Alice's Adventures in Wonderland and its sequel, Through the Looking Glass and What Alice Found There, creatively depended on the photographic images Carroll produced. Utilizing the four step process of creativity generally accepted by psychologists, Carroll's photographs are …

Functional Characterization Of Cytochrome B5 Reductase And Its Electron Acceptor Cytochrome B5 In Plasmodium Falciparum, Lucio Malvisi

USF Tampa Graduate Theses and Dissertations

Malaria is a disease of major public health importance, killing approximately one million people and causing about 250 million cases of fever annually. It mostly affects children under the age of five and pregnant women in many developing countries, making it a prominent issue in international health and maternal and child health. The most aggressive form of malaria is caused by the parasite Plasmodium falciparum which is responsible for 80% of infections and 90% of deaths from malaria, and is most prevalent in sub-Saharan Africa. Public Health interventions include the implementation of prevention programs, health education, and chemotherapy. The latter …

Architecture Of Materialism: A Study Of Craft In Design Culture, Process, And Product, Logan Mahaffey

USF Tampa Graduate Theses and Dissertations

It is estimated ten thousand hours of experience are required to master any given process (Sennett 20). Whether it is wood joinery, music, culinary arts or weaving, it is about making something that can be seen, heard, touched, and/or used. Society seems to be losing an appreciation for craft as an idea. Especially in the US, materialism has reduced quality and craftsmanship to merely a luxury to those that can afford a $10,000 Maloof chair or an $8000 Amish table. Developers build for maximum profit while buyers seek maximum square footage. Yet it seems while mainstream society continues to "progress", …

Heat Transfer Enhancement Of Spray Cooling With Nanofluids, Christian David Martinez

USF Tampa Graduate Theses and Dissertations

Spray cooling is a technique for achieving large heat fluxes at low surface temperatures by impinging a liquid in droplet form on a heated surface. Heat is removed by droplets spreading across the surface, thus removing heat by evaporation and by an increase in the convective heat transfer coefficient. The addition of nano-sized particles, like aluminum or copper, to water to create a nanofluid could further enhance the spray cooling process. Nanofluids have been shown to have better thermophysical properties when compared to water, like enhanced thermal conductivity. Although droplet size, velocity, impact angle and the roughness of the heated …
