Situating Contraceptive Practices And Public Health Strategy In The Bronx: Perspectives From Female Youth, Healthcare Workers, And Reproductive Health Leaders, Hannah Louise Helmy

USF Tampa Graduate Theses and Dissertations

In the United States, concerns about adolescent childbearing and its perceived corollaries – negative health outcomes for mother and child, the disintegration of the nuclear family, and “over-dependence” on public resources – began to circulate widely in policy spheres and popular media in the 1970’s, resulting in a proliferation of policies, programs, and services designed to address its prevention. Although national birth rates among adolescents are currently at their lowest since peaking in the early 1990’s, this decline masks persistent and significant disparities between groups of young people by race, ethnicity, geography, and poverty level. The concomitant existence of social …

Was It Something They Said? Stand-Up Comedy And Progressive Social Change, David M. Jenkins

USF Tampa Graduate Theses and Dissertations

From our earliest origins in every civilization across the globe, comic performances have fulfilled an important social function. Yet stand-up comedy has not attracted the serious academic inquiry one might expect. This dissertation argues that in the absence of public intellectuals stand-up comics are important to how we talk about and negotiate complicated issues like gender and race. These comic texts are sites of cultural critique, public discourse, tools for articulation, a means of persuasion, and serve to galvanize communities.

This dissertation argues that stand-up comedy performances are a vital part of modern American intellectual and social life and are …

Structure-Function Analysis Of The Dna Damage Repair Complex Str In Saccharomyces Cerevisiae, Jessica Ashley Kennedy

USF Tampa Graduate Theses and Dissertations

The RecQ family of helicases has been termed the “Caretakers of the Genome,” and rightfully so. These proteins are highly conserved from bacteria to humans and have been implicated in functions from homologous recombinatorial repair to damage checkpoint response to telomere maintenance and more. Mutant genes of three of the human RecQ helicases lead to syndromes characterized by a high incidence of cancer, premature aging and early death. Despite their implications in several biological functions and importance to the integrity of the human genome and suppression of cancer, many aspects of the RecQ family structure and function remain unknown. To …

USF Tampa Graduate Theses and Dissertations

This dissertation is a compilation of research and theoretical papers based on the affordances of multimodal literacies for marginalized learners and for pre-service teachers’ developing conceptualizations of literacy. Through a transdisciplinary lens, the author considers complex issues presented in traditional, print-based learning environments that potentially marginalize learners in their developing abilities to become successful participants in the multiple literacies in the real world.

Three studies focus on pre-service teachers and their developing understanding of effective literacy-related classroom practices. Chapter Three explores potential affordances of a multimodal learning environment for pre-service teachers with self-identified reading difficulties. The phenomenological study highlights differing …

Tell Sir Thomas More We've Got Another Failed Attempt: Utopia And The Burning Man Project, Gracen Lila Kovacik

USF Tampa Graduate Theses and Dissertations

Burning Man, a weeklong experience in Black Rock Desert, Nevada, has become an oasis for those looking to escape the corporatized grasp of modern culture. Burning Man serves as a reprieve from judgment and allows participants to embrace and perform their inner identities. The intensions of Burning Man have been widely debated, from scholars concentrating on the rejection of consumerism to analyzing sacred space and religious connectivity for festivalgoers. What deserves further analysis, however, is the utopian nature of the event. I will explore previous utopian attempts--literary, political, etc.--and define what characteristics from those societies were present during the inception …

Efficacy And Resistance Potential Of Jpc-3210 In Plasmodium Falciparum, Siobhan Marie Flaherty

USF Tampa Graduate Theses and Dissertations

Combating drug resistant malaria has been historically challenging, and remains so today. Recent reports from Southeast Asia show that Plasmodium falciparum is developing resistance to even our best defenses; artemisinin-based therapies. This development threatens to become a significant challenge in controlling malaria infections worldwide, making research into developing and characterizing new antimalarial drugs increasingly important. The purpose of this study was to characterize the resistance potential of novel antimalarial compound JPC-3210 in vitro using P. falciparum clones. JPC-3210 is a new long acting drug with potential to be used in combination with fast-acting drugs like artemisinins to cure drug resistant …

Half Empty/Half Full: Absence, Ethnicity, And The Question Of Identity In The United States, Ashley Josephine Martinez

USF Tampa Graduate Theses and Dissertations

This study helps us understand the complexities of transnational abandonment, and transnational abandonment in the context of Saudi heritage in particular. Based on a textual analysis of narratives on a blog by individuals abandoned by their Saudi fathers, my findings suggest that they discursively construct their identity in three ways: a) by negotiating their illegitimate status as perceived by many Saudis, and the validity of their search; b) by making sense of the absence of father and the cultural knowledge of the paternal side, while negotiating the inevitable presence of the father in many other ways and their ethnic difference; …

A Mixed Method Study Examining Synchronous-Enhanced Learning In Distance Education, Kimberly M. Wheeler

USF Tampa Graduate Theses and Dissertations

This mixed method study examined how integration of synchronous Web-based desktop conferencing affects undergraduate distance learning students' educational experience. Specifically, it compared students in one distance learning section of an introductory technology course delivered through a synchronous-enhanced mode (employing both synchronous and asynchronous tools) with students in a second section of the same distance learning course provided in the asynchronous only mode to examine variations in cognitive presence, social presence, and teaching presence through the lens of the Community of Inquiry model (Garrison, Anderson, and Archer, 2000). Additionally, this study measured perceived learning, learner-instructor interaction, and learner-learner interaction to determine …

Relational Agency, Networked Technology, And The Social Media Aftermath Of The Boston Marathon Bombing, Megan M. Mcintyre

USF Tampa Graduate Theses and Dissertations

Agency is a foundational and ongoing concern for the field of Rhetoric and Composition. Long thought to be a product and possession of human action, rhetorical agency represents the most obvious connection between the educational and theoretical work of the field and the civic project of liberal arts and humanities education. Existing theories of anthropocentric rhetorical agency are insufficient, however, to account for the complex technological work of digitally enmeshed networks of humans and nonhumans. To better account for these complex networks, this project argues for the introduction of new materialist theories of distributed agency into conversations about agency within …

Additives For Heat Transfer Enhancement In High Temperature Thermal Energy Storage Media: Selection And Characterization, Philip D. Myers Jr.

USF Tampa Graduate Theses and Dissertations

Inorganic salts are very promising as high-temperature heat transfer fluids and thermal storage media in solar thermal power production. The dual-tank molten salt storage system, for example, has been demonstrated to be effective for continuous operation in solar power tower plants. In this particular storage regime, however, much of the thermal storage potential of the salts is ignored. Most inorganic salts are characterized by high heats of fusion, so their use as phase-change materials (PCMs) allows for substantially higher energy storage density than their use as sensible heat storage alone. For instance, use of molten sodium-potassium eutectic salt over a …

Ikaros Deficiency Leads To An Imbalance In Effector And Regulatory T Cell Homeostasis In Murine Pancreatic Cancer, Nadine D. Nelson

USF Tampa Graduate Theses and Dissertations

Pancreatic cancer is one of the deadliest cancers with a five-year survival rate of 6%. Pancreatic cancer is resistant to conventional chemotherapy and is usually diagnosed at late stages. Current treatment options have minimal effects in extending patients' lives beyond 10 months. One significant limitation in developing treatments to combat pancreatic cancer is its immunosuppressive microenvironment. Pancreatic cancer secretes factors that activate immunosuppressive cells, such as regulatory T cells (Tregs). These Tregs suppress effector CD4⁺ and CD8⁺ T cell anti-tumor immune responses. Therefore, novel treatment options to reduce Treg-mediated immune suppression and increase the numbers and functions of …

Estudio Y Edición De La Más Constante Mujer De Juan Pérez De Montalbán, Philip Allen

USF Tampa Graduate Theses and Dissertations

La más constante mujer is a Spanish Golden Age play written by Juan Pérez de Montalbán in 1631 and published for the first time in 1632. Although he was once one of the most famous playwrights in Madrid, known for running in the same literary and social circles as Lope de Vega and Calderón de la Barca, the bulk of the dramatist's work has been greatly ignored by scholars, or is referred to as being of second rate, and the author himself has nearly tragically been forgotten throughout the centuries following his short life. Although research has been conducted to …

The Interaction Of Feedback And Reward Contingency On Cardiovascular Reactivity During A Stressful Cognitive Task, Alvin B. Jin

USF Tampa Graduate Theses and Dissertations

Excessive sympathetic cardiovascular reactivity to stressful tasks is a risk factor for the development of cardiovascular disease (CVD). Many populations with a greater risk for CVD instead demonstrate blunted cardiovascular reactivity to stressful tasks. The motivational intensity theory identifies how motivation and effort influence sympathetic reactivity. Blunted reactivity may be a potential index of motivational dysregulation, which leads to poor behavioral decisions such as excess smoking or alcohol use, in turn increasing the risk for CVD. The current study sought to demonstrate how inhibited effort due to poor ability feedback with a low-contingency reward could directly increase the risk for …

Not On My Street: Exploration Of Culture, Meaning And Perceptions Of Hiv Risk Among Middle Class African American Women, Corliss D. Heath

USF Tampa Graduate Theses and Dissertations

Black women remain at a higher risk for HIV infection than women of any other ethnic group. Of all new infections reported among U.S. women in 2010, 64% occurred in African Americans compared to 18% Whites and 15% Hispanic/Latina women (CDC 2013a; CDC 2014b). While the literature on HIV risk among African American women is extensive, it mostly focuses on low income, low education subgroups of women or those involved in high risk behaviors such as drug use. Very little has been done to understand the risk for HIV among college educated, middle class women who do not fit into …

The Effects Of Collaborative Critical Thinking Training On Trust Development And Effectiveness In Virtual Teams, Mark Grichanik

USF Tampa Graduate Theses and Dissertations

Workers in modern teams that perform tasks over computer-mediated communication channels encounter challenges in building trust and performing effectively. Finding interventions to mitigate such losses could improve team performance. Collaborative critical thinking (CCT) training has the potential to improve trust, monitoring, and effectiveness in virtual teams. Using a simulated search-and-rescue task, the effects of CCT training, as compared with a control training, were evaluated in 105 three-member teams. No effects of CCT training were found on team positive or negative monitoring, team cognitive or affective trust, team efficacy, or team viability. However, teams trained in CCT reported consistently higher levels …

The Birth Of A Nation: The Case For A Tri-Level Analysis Of Forms Of Racial Vindication, Charles Fred Hearns

USF Tampa Graduate Theses and Dissertations

Early American film scholars often critique the relative ineffectiveness of a single literary work, protest movement or silent film to achieve racial vindication following the release of The Birth of a Nation in 1915. Thomas Cripps, for example, examines a relatively ineffective isolated attempt to counter the notions of White supremacy promoted in the film. This study makes the case for applying a non-traditional tri-level analysis when measuring the effectiveness of such attempts. The paper focuses on efforts to redeem the image and the potential of African Americans after 1915 in the Black public sphere in three concurrent vehicles: the …

Thermal Assessment Of A Latent-Heat Energy Storage Module During Melting And Freezing For Solar Energy Applications, Antonio Miguel Ramos Archibold

USF Tampa Graduate Theses and Dissertations

Capital investment reduction, exergetic efficiency improvement and material compatibility issues have been identified as the primary techno-economic challenges associated, with the near-term development and deployment of thermal energy storage (TES) in commercial-scale concentrating solar power plants. Three TES techniques have gained attention in the solar energy research community as possible candidates to reduce the cost of solar-generated electricity, namely (1) sensible heat storage, (2) latent heat (tank filled with phase change materials (PCMs) or encapsulated PCMs packed in a vessel) and (3) thermochemical storage. Among these the PCM macro-encapsulation approach seems to be one of the most-promising methods because of …

Experimentally Evaluating Statistical Patterns Of Offending Typology For Burglary: A Replication Study, Lance Edwin Gilmore

USF Tampa Graduate Theses and Dissertations

This study used a quasi-experiment in order to evaluate the effect the SPOT-burglary profile on burglary arrest rates. A single police agency split into three different districts was used for the quasi-experiment. The SPOT-burglary profile was implemented in one district, while leaving the other two as control groups. The differences between the districts were controlled for using a statistical analysis. Burglary arrest rates were collected each month for all three districts for a period of one year before the implementation, and for six months after the implementation. Results show that the district who received the SPOT-burglary profile raised their burglary …

Love And (M)Other (Im)Possibilities, Summer Renee Cunningham

USF Tampa Graduate Theses and Dissertations

This dissertation is a performative interrogation of the disagreement and (dis)interest, communication issues, surrounding motherhood in contemporary U.S. culture. Textual analysis of Mary Kelly's Post-Partum Document (PPD) plays a key role in my inquiry. I juxtapose documentation from my lived experiences and academic projects with Kelly's work to build upon the themes and ideas introduced throughout PPD. This project is guided by the concepts love and (im)possibility, and I will argue that, together, they are central to understanding mothering/caregiving as a site of communication inquiry. Love and (im)possibility are inherent to both mothering and communication, but they also are essential …
