Modeling Endogenous Treatment Eects With Heterogeneity: A Bayesian Nonparametric Approach, Xuequn Hu

USF Tampa Graduate Theses and Dissertations

This dissertation explores the estimation of endogenous treatment effects in the presence of heterogeneous responses. A Bayesian Nonparametric approach is taken to model the heterogeneity in treatment effects. Specifically, I adopt the Dirichlet Process Mixture (DPM) model to capture the heterogeneity and show that DPM often outperforms Finite Mixture Model (FMM) in providing more flexible function forms and thus better model fit. Rather than fixing the number of components in a mixture model, DPM allows the data and prior knowledge to determine the number of components in the data, thus providing an automatic mechanism for model selection.

Two DPM models …

Constructing Alternative Christian Identity: An Ethnography Of Jesus People Usa's Cornerstone Festival, Brian Johnston

USF Tampa Graduate Theses and Dissertations

This dissertation examines processes through which alternative Christian identities are constructed, maintained, and performed at the annual Cornerstone Festival in Bushnell, Illinois. Organized and managed by Jesus People USA (JPUSA), an urban commune in Chicago, Illinois, the festival includes non-traditional methods of religious expression including rock music, making camp, play, and community-building. Cornerstone Festival attracts and includes members of the Christian faith who would not otherwise be included in traditionally organized Christian groups and fosters interaction between these less enfranchised members and more traditionally minded and socialized Christian practitioners. JPUSA appropriates the festival format as a method of religious expression …

When Does Fidelity Matter? An Evaluation Of Two Medical Simulation Methods, Nneka Joseph

USF Tampa Graduate Theses and Dissertations

Job or task simulations are used in training when the use of the real task is dangerous or expensive, such as flying aircraft or surgery. This study focused on comparing two types of simulations used in assessments during a Clinical Performance Examination of third-year medical students: computer enhanced mannequins and standardized patients. Each type of simulation has advantages, but little empirical work exists to guide the use of different types of simulation for training and evaluating different aspects of performance. This study analyzed performance scores for different competencies as well as the reliability and validity of the different simulation types. …

Goal Compatibility And Emotional Intensity: An Experimental Study Of Graphic Images In Strategic Communication, Lauren Marie Klinger

USF Tampa Graduate Theses and Dissertations

The purpose of this quantitative study is to examine receiver variables involved in strategic communications and to look specifically at the use of graphic images in strategic communication materials. It argues that any complete, general model of persuasion effects will include both goal compatibility and emotional determinants. It argues that some influential theories used in strategic communications scholarship, including the situational theory of publics and the elaboration likelihood model, are incomplete because they have omitted these variables. This study also tests variables related to willingness to communicate, behavioral intention, and attitude towards the organization. These variables are drawn from prominent, …

Rethinking Buffer Operations In A Dual-Store Framework, Melissa Lehman

USF Tampa Graduate Theses and Dissertations

Atkinson and Shiffrin's (1968) dual-store model of memory includes a structural memory store along with control processes conceptualized as a rehearsal buffer. I present a variant of Atkinson and Shiffrin’s buffer model within a global memory framework that accounts for findings previously thought to be difficult for it to explain. This model assumes a limited capacity buffer where information is stored about items, along with information about associations between items and between items and the context in which they are studied. The strength of association between items and context is limited by the number of items simultaneously occupying the buffer. …

Saved By The (Alexander Graham) Bell: An Analysis Of Synchronous Communication And Student Satisfaction / Retention Rates In The First Year Online Composition Classroom, Jennifer Jane Lynch

USF Tampa Graduate Theses and Dissertations

Online first-year writing courses, with all of their promise, still maintain alarmingly low retention and student satisfaction rates, driving online curriculum designers to take another look at ways to increase both retention and satisfaction. To replicate the high rates of face-to-face classes, we must revisit and revise our approach to communication in the first-year writing online classroom. Think about it: The online classroom has abandoned a mainstay in education for thousands of years - synchronous communication. Why have we been so quick to dispose of it? Are we now paying the price?

This research will provide additional value to the …

New Media Photographic Representations Of Women`S Collegiate Volleyball: Game Faces, Action Shots, And Equipment, Alicia Pack

USF Tampa Graduate Theses and Dissertations

Researchers consistently find that mainstream media often represent women athletes in stereotypical ways including trivialization, sexualization, infantilization, passivity, and utilization of camera down-angles. However, research on new media's visual representation of women athletes is still in its infancy. This study adds to the growing literature on new media's representation of women athletes and concurs with previous findings suggesting that new media might be an outlet that can counter old media gender stereotypes. This thesis used mixed methods of qualitative content analysis and photovoice in order to better understand how Big East volleyball players are represented in photographs on websites: Instances …

Does D-Cycloserine Augmentation Of Cbt Improve Therapeutic Homework Compliance For Pediatric Obsessive Compulsive Disorder?, Jennifer M. Park

USF Tampa Graduate Theses and Dissertations

D-cycloserine (DCS), a partial agonist that acts on the N-methyl-D-aspartate (NMDA) receptor of the glutamatergic receptor complex, may enhance fear extinction learning during exposure-based therapy. Clinical studies in adults with obsessive-compulsive disorder (OCD) and non-OCD anxiety disorders - and a recent trial in pediatric OCD - have shown that DCS can improve treatment response to exposure therapy relative to placebo and exposure therapy. Some have hypothesized that improved treatment response is a function of increased compliance and engagement in therapeutic homework tasks, a core component of behavioral treatment. The present study examined the relationship between DCS and homework compliance in …

Framing 10/12 And 3/11 In American And European News, Andrea Lypka

USF Tampa Graduate Theses and Dissertations

This media analysis of the incidents in Bali in 2002 (10/12) and Madrid in 2004 (3/11) reveals the black and white portrayal of these attacks in western news through the localization of international terrorism occurrences, pro-government perspective, and internalization of U.S. policies. The Old Europe and New Europe debate further fractures the European press. Such rhetoric perpetuates the "us versus them" schism by contrasting the goals of the alleged perpetrators with the western values of democracy and freedom. Governmental sources remain central news sources during these crises. In addition, 9/11, war on terrorism, and fear from further attacks dominate news …

Internet Use And Economic Development: Evidence And Policy Implications, Joseph J. Macdougald

USF Tampa Graduate Theses and Dissertations

This dissertation explores how Internet use impacts four different measures of economic development using several econometric techniques on multi-country panel data. The economic development outcomes investigated are: per capita GDP, per capita export revenues, per capita market capitalization, and societal well-being as measured by the United Nations Human Development Index (HDI). Data from the World Bank, the International Telecommunication Union, and the United Nations –covering 202 countries over the period 1996 to 2007– are combined to allow for empirical investigation using dynamic panel data and finite mixture model estimation techniques on the total sample and subsamples stratified by country income …

The Role Of Microvascular Complications In The Relationship Between Glycemic Control And Depressive Symptomatology In Patients With Type 1 Diabetes: A Mediational Study, Laura Lynn Mayhew

USF Tampa Graduate Theses and Dissertations

People with diabetes are at double the risk of developing depression. Depression is associated with increased morbidity and mortality in people with diabetes. Levels of A1c have been linked to microvascular complications (e.g., retinopathy, nephropathy, and neuropathy) as well as depression. The interrelationship between A1c, microvascular complications, and depression has not previously been investigated in a comprehensive model, and a better understanding of the nature of these associations is needed. Preliminary analyses test the assumption that A1c mediates the relationship between group assignment in the Diabetes Control and Complications Trial (DCCT) and microvascular complications. The primary purpose of the study …

The Influence Of Meteorological Parameters On Rainfall And Severe Weather In Pinellas County, Fl, Cristina A. Mazza

USF Tampa Graduate Theses and Dissertations

Pinellas County is located on a peninsula in Florida that experiences daily patterns of sea breeze associated rainfall mainly during the summer months of June through August. Previously, rainfall patterns, amounts and timing and severe weather in Pinellas County have not been examined considering dominant wind flow patterns, sea breeze circulations and other atmospheric variables. To improve forecasting of local mesoscale phenomena, this project examined the rainfall patterns, amounts and timing and severe weather occurrences that occur as a result of sea breezes and associated prevailing wind regimes within Pinellas County for the months of June, July and August for …

Epidemiological Study Of Contributing Factors In The Development Of Peptic Ulcer And Gastric Cancer Initiated By Helicobacter Pylori Infection In India, Rahul Suresh Mhaskar

USF Tampa Graduate Theses and Dissertations

Background: Helicobacter pylori (H. pylori) infection is a significant risk factor for peptic ulcer (PU) and gastric cancer (GC). Apart from the virulent CagA genotype of H. pylori environmental and dietary factors influence disease outcomes. There have been no studies addressing these factors in Western India. Hence, we conducted a case control study enrolling PU, GC patients and controls at Pune, India.

Methods: Risk factors for PU and H. pylori infection were assessed in participant interview. H. pylori status was assessed from stool by monoclonal antigen detection. To understand treatment effect, we followed 100 H. pylori positive patients.

Results: We …

Down, But Not Out: An Ethnographic Study Of Women Who Struggled With And Overcame Methamphetamine Addiction, Jodi Nettleton

USF Tampa Graduate Theses and Dissertations

Women suffer methamphetamine (meth) addiction at a rate much higher than rates for addiction to other drugs. Female meth users are susceptible and predisposed to gender-related risks: high rates of unprotected vaginal and anal sex, sex-work, and sexual coercion. Precursors for addiction (e.g., abuse, body dysphasia) put females in a difficult position for recovery and highlight the need for gender-specific research and treatment.

Methamphetamine (a synthetically derived stimulant) creates psychological and physical dependency that affects every neuron of the brain and damages the body immediately. Women ingest meth for initial effects that allay social pressures: feeling euphoric, connecting with others …

African American Athletes And The Negotiation Of Public Spaces: An Examination Of Athletic Capital And African American Perceptions Of Success, Keona Lewis

USF Tampa Graduate Theses and Dissertations

This dissertation explores the culture of sport among African American male football players as well as African American perspectives on sport and success. A case study of six African American, Division 1 FBS (Football Bowl Subdivision) collegiate student athletes was conducted along with seventeen supplemental interviews with community members, parents, coaches and former athletes and fans. The participants answered questions that explored education, success, identity construction, ethnicity and sport. Archival data was also reviewed framing the discussion on football in Florida, links between education and sport participation and African American male academic achievement. While many perspectives varied, there were collective …

A Multi-Level Study Investigating The Impact Of Workplace Civility Climate On Incivility And Employee Well-Being, Raymond Charles Ottinot

USF Tampa Graduate Theses and Dissertations

This study used Zohar‟s (2000) multi-level model of climate to examine the extent to which shared perceptions of workplace civility climate relate to teacher job satisfaction, affective commitment, and counterproductive work behaviors (CWB-abuse) towards other teachers. Workplace civility climate is defined as employee perceptions of how management uses policies, procedures, and practices to maintain a civil workplace. An online-survey was used to assess a cross-sectional sample of K-12 teachers (N = 2222) nested in 207 schools in a large US school district. There was adequate agreement among teacher perceptions of school civility climate for aggregation and between-group variance of civility …

Inactivation Of Ascaris Suum By Ammonia In Feces Simulating The Physical-Chemical Parameters Of The Solar Toilet Under Laboratory Conditions, Ligia Maria Cruz Espinoza

USF Tampa Graduate Theses and Dissertations

Access to sustainable sanitation systems is a determining factor in human health and economic development. However, more than a third of the world’s population lives without access to improved sanitation facilities. To meet the sanitation United Nations Millennium Development target, "halve, by 2015, the proportion of people without sustainable access to safe drinking water and basic sanitation", a wide range of non conventional sanitation technologies have been implemented in developing countries, including waterless systems. These systems function by diverting urine away from feces and collecting, storing, and dehydrating the fecal material in watertight dehydration vaults. From a public …

More Than Bows And Arrows: Subversion And Double-Consciousness In Native American Storytelling, Anastacia M. Schulhoff

USF Tampa Graduate Theses and Dissertations

W. E. B. Du Bois‘ legendary reflections on the ―peculiar sensation, this double-consciousness, this sense of always looking at one‘s self through the eyes of others‖ has been applied almost exclusively to the souls of African American people (Du Bois 1903). This thesis shows how the concept of double-consciousness is alive in the stories told by Native Americans. I draw upon data from two websites that have recorded the stories told by ―exemplary indigenous elders, historians, storytellers and song carriers‖ and their oral traditions that serve the ―purpose of cultural preservation, education, and race reconciliation‖ (Wisdom of the Elders, 2009). …

Phenotypic And Genotypic Analysis Of In Vitro Selected Artemisinin Resistant Plasmodium Falciparum, Matthew Scott Tucker

USF Tampa Graduate Theses and Dissertations

Artemisinin and its derivatives provide faster clearance of parasitemia than any other antimalarial drugs and these drugs are part of frontline combination therapies in areas where drug-resistant Plasmodium falciparum exists. Clinical resistance to artemisinins is emerging on the Thailand-Cambodia border, making it imperative to investigate mechanisms of artemisinin resistance. Previous work in our laboratory showed ring-stage parasites enter a dormant state after exposure to artemisinin. We hypothesize that this period of dormancy is directly related to recrudescence and prolonged parasite clearance times in patients, and possibly resistance. The target of artemisinin is currently unknown, and potential resistance mechanisms are not …

The Relationship Between Knowledge And Beliefs About Human Papillomavirus, Acceptance Of The Human Papillomavirus Vaccine, And Intentions To Practice Safer Sex Behaviors Among Female College Students, Theresa Scorcia-Wilson

USF Tampa Graduate Theses and Dissertations

Introduction. Sexually transmitted infections (STIs) continue to be highly prevalent among young women, and STIs continue to be a challenging health issue on college campuses. Studies have shown that the highest prevalence of human papillomavirus (HPV) is among young adult women, ages 20 to 24, including female college students. While the HPV vaccine has proven to be highly effective in preventing certain high-risk types of HPV, it is not effective in preventing all types of HPV or other STIs. Practicing other safer sex behaviors, in addition to condom use, also can help individuals protect themselves and their partners from …

Body Depilation Among Women And Men: The Association Of Body Hair Reduction Or Removal With Body Satisfaction, Appearance Comparison, Body Image Disturbance, And Body Dysmorphic Disorder Symptomatology, Michael Scott Boroughs

USF Tampa Graduate Theses and Dissertations

Body depilation, or the reduction or removal of body hair, is a relatively new area of research inquiry. Although women in many industrialized cultures have engaged in depilation for several decades, this behavior has been documented only recently among men. Though originally thought to be widely practiced by women and only a small proportion of men, including athletes or bodybuilders, recent studies suggest that more men engage in body depilation than previously hypothesized. In fact, one recent study estimated the prevalence of men's body depilation at 83.7% which suggests that men are depilating at rates similar to women. Nevertheless sparse …

Core Promoter Function In Brugia Malayi, Michelle Bailey

USF Tampa Graduate Theses and Dissertations

Previous studies have indicated that the promoters of the human filarial parasite Brugia malayi are unusual in that they do not exhibit the CAAT or TATAA sequences usually found in the core domains of promoters of most eukaryotic organisms. Analysis of the promoters of the ribosomal proteins showed that the region flanking the splice leader (SL) addition site plays an important role in transcription and may function as the core promoter domain in B. malayi. To test the hypothesis that the SL addition domain is the most important essential region of the ribosomal protein promoters, the SL addition site of …

An Ethnography Of The Bay Area Renaissance Festival: Performing Community And Reconfiguring Gender, Matthew Johnson

USF Tampa Graduate Theses and Dissertations

This performance ethnography analyzes the means by which performers at Tampa, Florida‘s Bay Area Renaissance Festival constitute community and gender through performance. Renaissance Festivals are themed weekend events that ostensibly seek to allow visitors to experience life in an English Renaissance village. Beginning with the theoretical assumption that performance is constitutive of culture, community, and identity, and undergirded by David Boje‘s festivalism, Richard Schechner‘s restored behavior, Victor Turner‘s liminoid communitas and Judith Butler‘s performative agency, The Festival is explored as a celebratory community that engages in social change through personal transformation.

Employing reflexive ethnography and narrative as inquiry, Chapter Two …

The Role Of Rater Motivation In Personnel Selection Validation Studies, Dan Ispas

USF Tampa Graduate Theses and Dissertations

Personnel selection validation studies are routinely conducted in contemporary organizations for selecting and placing employees. Although numerous studies have been conducted with the goal of identifying new predictors, less research was focused on the criterion side. In the current paper, across three studies and five samples, I examined the role played by rater motivation in validation studies. I proposed that rater motivation would impact criterion-related validity of various predictors, the reliability, and the variance of performance ratings. In Study 1, these hypotheses were tested in two samples with varied operationalizations of predictors and of rater motivation. In Study 2, I …

The Positive- And Negative-Right Conceptions Of Freedom Of Speech And The Specter Of Reimposing The Broadcast Fairness Doctrine ... Or Something Like It, Adam Fowler

USF Tampa Graduate Theses and Dissertations

A key theoretical debate underlying the now defunct Federal Communications Commission (FCC) regulation known as the Fairness Doctrine is conflict over what constitutes the right to freedom of speech: a positive or negative conception. Similarly, since repeal of the Doctrine, other FCC measures to uphold the “public-interest” standard in broadcasting have relied on a positive conception of speech. This thesis demonstrates the history of this debate through court cases, news reports, scholarly articles and historical documents. It then is argued that the positive-right nature of these regulations is problematic philosophically, constitutionally and practically. The positive-right conception lends itself to an …

An Ecology Of Performance: Gregory Bateson's Cybernetic Performance, Daniel Matthew Blaeuer

USF Tampa Graduate Theses and Dissertations

This dissertation is a case study of the public performances of Gregory Bateson at The Esalen Institute. The case study is a reconsideration of the work of Gregory Bateson from the perspective of performance studies. The author brings together performativity, cybernetics, and the sacred to argue that Gregory Bateson, in his public performances, was striving for grace in encounters with others. The author has conducted archival research into Bateson’s presentations and has spoken with several close to Bateson to get a sense of how his process of public presentation paralleled his ideas—a process of continually working through ideas in conversation …

Bastards, Brains, Boobs And Performance: A Retrospective Account, Joanna Bartell

USF Tampa Graduate Theses and Dissertations

The two essays that comprise this thesis use personal narrative to discuss various aspects of illness, resistance and the body. The first essay uses performance theory to explore the social structures, mandates and restrictions concerning illness. I use the cancer experience to explore the co-creation of self, identity, and modes of being between "performer" and "audience." "Performer," in this case, is the "breast cancer patient," and the "audience" is comprised of the "social others.” The second essay explores cyborgization of the body, its painful effects, and associated social and moral values. It also discusses how we create theory and understanding …

Examining The Relationship Between Work-To-Family Conflict And Parenting Behavior, Eunae Cho

USF Tampa Graduate Theses and Dissertations

Although work-family conflict (WFC) has been of particular interest to work-family researchers, little attention has been paid to the consequences of WFC that reside in the family domain. Research on WFC and child outcomes is especially scant. The current study addresses the gap in the literature by investigating the relationship between work-interfere-with-family (WIF) and three forms of parent-child interaction behavior (PB): physical and recreational PB (PRPB), cognitive and academic-oriented PB (CAPB), and passive and maintenance-oriented PB (PMPB). The mechanism by which WIF relates to PB was further investigated by examining negative emotion as a mediator and trait guilt as a …

An Analysis Of The Influence Of Sampling Methods On Estimation Of Drug Use Prevalence And Patterns Among Arrestees In The United States: Implications For Research And Policy, Janine Kremling

USF Tampa Graduate Theses and Dissertations

Using data from the Drug Use Forecasting (DUF) and the Arrestee Drug Abuse Monitoring (ADAM) programs collected by the National Institute of Justice the question whether the drug estimates of DUF, using a non-probability sample, and the drug use estimates of ADAM, using a probability sample, yield substantially different results will be explored. The following main questions will be addressed using equivalence analysis: Are there substantial differences in the DUF and ADAM samples with regard to the drug use information obtained from arrestees at nine sites across the United States? The analysis suggests that the drug use information contained in …

Ac/Dc: Let There Be Hybrid Cooling, Christopher Podes

USF Tampa Graduate Theses and Dissertations

In today’s increasingly energy conscious society, the methods of providing thermal comfort to humans are constantly under scrutiny. Depending on the climate, and the comfort requirements of the occupants, buildings can be designed to heat and cool occupants with passive methods, as well as mechanical methods. In the subtropics, where buildings often need to be heated in the winter and cooled in the summer, a synthesis of these two methods would be ideal. However, there is a disconnect between the integration of passive cooling and mechanical air conditioning, in subtropical architecture.

A study of user attitudes, based out of Australia, …
