Cost Of Treatment Of Asthma Attacks In A Tertiary Level Healthcare Hospital In Panama, Nydia Flores Chiari

USF Tampa Graduate Theses and Dissertations

Asthma is a chronic respiratory disease characterized by inflammation of the airway and the presence of recurrent attacks (exacerbations) of breathlessness, wheezing, cough, chest tightness, or some combination of these symptoms. In the US, about 53% of people with asthma had an asthma attack in 2008, and 57% of these, were children. One in ten children (10%) had asthma in 2009, and boys were more likely than girls to have asthma. Internationally, the prevalence of asthma varies widely in different countries, but the disparity is narrowing due to rising prevalence in low and middle income countries. Unfortunately, we do not …

Exploring The Motives, Perceptions And Constructed Identities Of The Facilitators For One Regional Council Of A Positive Youth Development Program: Girls On The Run, Ashley Ann Gallentine

USF Tampa Graduate Theses and Dissertations

The purpose of this study is to explore the coaches' perceptions, motives and constructed identities by participating in a regional physical activity-based positive youth development program. There is growing evidence that suggests the success of positive youth development (PYD) programs depend on the environment that is created by caring adult mentors. These coaches are the delivery vehicles for these programs and play an essential role in the development of participating youth. As a result, the characteristics these coaches possess are critical to the success of the PYD implementation. Based on the application of anthropological methods and theory, this study seeks …

Unbearable Weight, Unbearable Witness: The (Im)Possibility Of Witnessing Eating Disorders In Cyberspace, Kristen Nicole Gay

USF Tampa Graduate Theses and Dissertations

This thesis argues that the recent erasure of digital pro-anorexia ("pro-ana") narratives by websites such as Tumblr, Pinterest, and Instagram represents an attempt to silence female self-starvers and reify the authority of medical associations to speak for female bodies. I draw parallels between these attempts and Gayatri Chakravorty Spivak's theory of epistemic violence, since the experiences of women are effectively discredited, through metaphors that render the thin body dangerous, to shore up professional medical authority. As an attempt to privilege the experiences of the self-starvers, I analyze one Tumblr blog with eating disorder content to listen to the letters users …

Development Of Catalytic Technology For Producing Sustainable Energy, Syed Ali Z Gardezi

USF Tampa Graduate Theses and Dissertations

This dissertation explores catalyst technology for the production of renewable liquid fuels via thermo-chemical conversion of biomass derived syngas. Fischer-Tropsch synthesis is a process for converting syngas, i.e. a mixture of CO and H2, into energy rich long chain hydrocarbons and oxygenated compounds. This synthesis process involves a number of elementary reactions leading to an array of polymeric products. The economic operation of an FTS process lie in the interplay of both catalyst and reactor design. In relation to catalysis, the nature of chemisorbed species, and the fractional availability of active metal sites determines rate, conversion and yield. Similarly, reactor …

Examining The Ontoepistemological Underpinnings Of Diversity Education Found In Interpersonal Communication Textbooks, Tammy L. Jeffries

USF Tampa Graduate Theses and Dissertations

This project examines the ontoepistemological underpinnings of diversity education in the field of communication by focusing on the points where diversity, pedagogy and communication intersect. In this study I seek to understand how we come to know what we know about diversity, or the social construction of differentness, and how we share this information with others. I analyzed three popular interpersonal communication textbooks, examining the patterns revealed in the text, in order to address these questions.

This study uses three complimentary methods to reveal the number of occurrences that center on diversity in the text (content analysis), to interpret themes …

Continuous Electrowetting In Passivating And Non-Passivating Systems, Mehdi Khodayari

USF Tampa Graduate Theses and Dissertations

Electrowetting is an electromechanical response that can be used to change the equilibrium

shape of droplets on a surface through the application of an electric potential. By applying this potential asymmetrically to a droplet, the droplet can be moved. Typical electrowetting devices use an electrode covered by a dielectric to reduce electrochemical interactions. Successful electrowetting requires electrodes and dielectric layers that can resist damage through many cycles of voltage.

Continuous Electrowetting (CEW) is performed on high resistivity silicon wafers. In this process, when an electric potential difference is applied between the substrate ends, the droplet on the substrate moves towards …

The Role Of Acquired Capability As A Differentially-Specific Risk Factor For Disordered Eating And Problematic Alcohol Use In Female College Students: A Measure Development And Validation Study, Christa D. Labouliere

USF Tampa Graduate Theses and Dissertations

Traditional college students are members of an age bracket noted for high levels of risky behavior, and research has shown that certain risky behaviors, such as disordered eating and problematic alcohol use, are particularly common among undergraduates. It is well established that certain events in the learning history predispose vulnerable persons to engage in maladaptive risky behaviors. What is less clear is why some persons facing these events go on to develop maladaptive behavior while others do not, or why people facing similar events develop different varieties of maladaptive behaviors. Current research has focused extensively on risk factors that are …

Modeling Nitrogen Transformations In A Pilot Scale Marine Integrated Aquaculture System, Brian Mccarthy

USF Tampa Graduate Theses and Dissertations

Integrated aquaculture systems (IAS) are a type of recirculating aquaculture systems (RAS) where the wastewater is treated and returned to the fish tanks. The important difference between the two is that in an IAS, wastes from the aquaculture component are recovered as fertilizer to produce an agricultural product whereas in an RAS, waste organics, nutrients and solids are treated and discharged. A pilot marine IAS at Mote Aquaculture Research Park in Sarasota, FL was studied for this project. Water quality monitoring, measurements of fish health and growth rates of fish and plants were performed over a two-year period to determine …

Understanding Amphibian Decline: The Role Of Pesticides And The Pathogenic Chytrid Fungus On Amphibians And Aquatic Communities, Taegan A. Mcmahon

USF Tampa Graduate Theses and Dissertations

Amphibians are the most threatened taxon on the planet. Declines have been associated with over-exploitation, habitat loss, pollution, and pathogenic diseases, but of these factors, pollution and disease have been relatively under-studied. Here, I investigated: 1) the impacts of commonly used pesticides on aquatic communities, 2) the effect of these pesticides on amphibian susceptibility to the pathogenic chytrid fungus, Batrachochytrium dendrobatidis (Bd), and 3) whether there are non-amphibian hosts of Bd and 4) how to best quantify the survival of Bd through ontogeny of the host.

In my first research chapter, I quantified the effects of environmentally relevant concentrations of …

Fertile Ground For A Social Movement: Social Capital In Direct Agriculture Marketing, Elizabeth A. Murray

USF Tampa Graduate Theses and Dissertations

Building from existing literature on anthropology of food, political economy of food and consumption, and social movement theory, I examine the direct agriculture network of Tampa Bay Florida through a mixed-method ethnography. The research consisted of one year of field-work, with 6 months and over 100 hours of active participant observation, open-ended interviews with eight local producers, and short surveys with 100 market patrons. This thesis is an analysis of the results of this rigorous qualitative and quantitative work and, perhaps more importantly, an account of my own personal struggles in joining the direct agriculture network and my ultimate commitment …

The Strong Black Woman, Depression, And Emotional Eating, Michelle Renee Offutt

USF Tampa Graduate Theses and Dissertations

Abstract

Eighty percent of all black women are overweight or obese which can lead to greatly increased morbidity and mortality, increasing healthcare costs and loss of healthy years of life. While multiple factors may contribute to obesity in black women, the cultural persona of the Strong Black Woman (SBW), an ideology that promotes unflagging toughness and denial of self-needs, may be the basis for behaviors that contribute to steady state obesity in this group. The purpose of this study was to investigate the relationships between the SBW persona, depression, and emotional eating.

Two predominately black churches in Florida were approached …

The 2008 Candlelight Protest In South Korea: Articulating The Paradox Of Resistance In Neoliberal Globalization, Huikyong Pang

USF Tampa Graduate Theses and Dissertations

My dissertation is a speculative analysis of the historical contexts of a social protest, based on the notion of "articulation" advanced in the field of cultural studies. Focusing on the 2008 candlelight protest against U.S. beef in South Korea, my goal is to explore the historical contexts of the protest, which formulate the identity of the protest. Since the U.S. beef deal was approved by the Korean government as a precondition for the Free Trade Agreement between Korea and the United States, the protest has been considered (notably by leftists in Korea) as a resistance against post-colonial overtones and fascist …

Compassionate Storytelling With Holocaust Survivors: Cultivating Dialogue At The End Of An Era, Chris J. Patti

USF Tampa Graduate Theses and Dissertations

We live in a frantic, fractured, ever-quickening, and violent world that is at the end of the era in which we will be able to talk with survivors of the Shoah. To date, there have been approximately 100,000 recorded interviews of Holocaust survivors. The vast majority of these interviews--such as the 52,000 done for Steven Spielberg's and USC Shoah Foundation Archive--have used traditional, single-session, and "neutral" methods of oral history interviewing to "capture" and "preserve" the legalistic, historical "testimonies" of survivors. The present study responds to this situation and unique moment in time by slowing down, listening, speaking repeatedly and …

Impacts Of U.S. Foreign Policy And Intervention On Guatemala: Mid-20th Century, Patricia M. Plantamura

USF Tampa Graduate Theses and Dissertations

International Relations theory includes realist concepts of sovereign nation-states interacting in an anarchic world as they rationally determine their own national interests based upon ever-changing competition for power. In this interplay for power, nation-states may affect each other politically, economically, ideologically or militarily. This thesis focuses on effects of U.S. foreign policy and U.S. intervention in Guatemala in the time period surrounding the Guatemalan Revolution (1944-1954), with its "liberation" in 1954, and then into the early 1960s as the Guatemalan state began to be militarized. In this thesis I will answer the following question:

How did the United States affect …

Socioeconomic Factors' And Water Source Features' Effect On Household Water Supply Choices In Uganda And The Associated Environmental Impacts, Christine M. Prouty

USF Tampa Graduate Theses and Dissertations

Over the last twenty years or more, Uganda has benefitted from significant strides in water and sanitation initiated by the United Nations' Millennium Development Goals. While the rapid progress towards development has been vastly beneficial, it is also important that it does not occur at the expense of the environment. The environmental impacts of these water sources must be evaluated and understood. However, to develop a robust understanding of the impact requires inclusion of the community members who use these sources and their perceptions of them. Consequently, the goal of this research is to investigate the interrelationships between socioeconomic factors, …

Cultivating Local: Building A Local Food System In Western North Carolina, Allison S. Perrett

USF Tampa Graduate Theses and Dissertations

This dissertation examines a movement in Western North Carolina to build a local food system, one grounded in the conditions and relationships of place. In 2000, Mountain Family Farms launched the Local Food Campaign to raise public awareness about the region's farms and farming heritage, to educate consumers about the benefits of buying food grown by local farms, and, ultimately, to build markets for locally grown food to sustain the region's farms. The campaign sparked a social movement and over a decade later local farms and locally grown food are a palpable feature of life in the mountains of Western …

Negotiating Race-Related Tensions: How White Educational Leaders Recognize, Confront, And Dialogue About Race And Racism, Amy Jo Samuels

USF Tampa Graduate Theses and Dissertations

Despite exposure of educational disparities for students of color, as well as the notion that educational training rarely discusses race and racism, there continues to be a lack of discourse on race, racism, and anti-racism in educational leadership. Subsequently, it is important to challenge deficit thinking and encourage further examination of the deeply-rooted foundation of oppression. The study explored personal narratives of white educational leaders who oppose racial inequity to heighten awareness about conceptualizations of race, racism, and anti-racism. The research involved interviewing educational leaders in three groups: 1) aspiring, 2) currently-practicing, and 3) recently-retired. Eight participants were selected to …

Sense Of Place In An Unincorporated Community:, Samuel Scott Sanderson

USF Tampa Graduate Theses and Dissertations

Abstract

Residents of communities that are at the edge of the rural-urban divide are likely to have many senses of place reflective of the changes occurring around them. As the place where they have resided in and identify with becomes transformed by changes in land use and social composition, these residents may be forced to either adapt or leave. Often overlooked, these individuals may feel as if the place where they have long resided is no longer their home. As the familiar routes, stores, and neighborhoods give way to new highways, big name stores, and exclusive subdivisions, their understanding of …

Mass Spectrometry-Based Methods For The Detection And Characterization Of Protein-Tyrosine Nitration, Kent W. Seeley

USF Tampa Graduate Theses and Dissertations

Protein tyrosine nitration (PTN) is a posttranslational modification resulting from oxidative/nitrosative stress that has been implicated in a wide variety of disease states. Characterization of PTN is challenging due to several factors including its low abundance in a given proteome, preferential site modification, multiple target site proximity within unique peptide sequences, and analytical method and instrument limitations. Current analytical techniques are insufficiently sensitive to identify endogenous nitration sites without incorporation of either nitrotyrosine or target protein enrichment. However, enrichment proficiency can also be inadequate. Chemical derivatization of the nitro- moiety can be incomplete or result in undesirable byproduct formation, while …

Fracking Teco: Analyzing The Communication Strategies In Teco Peoples Gas Advertisements, Magdaline Southard

USF Tampa Graduate Theses and Dissertations

Abstract

TECO advertisements promote the use of natural gas as an energy source because it claims that natural gas is an environmentally responsible alternative to other sources of energy. However, these advertisements do not reveal the not-so-green process, namely hydraulic-fracturing, or fracking, by which natural gas is produced and the consequences that it can and does have on public health and the environment. Even though the conversation about fracking has been on the rise in recent years as certain companies and politicians have pushed for an increase in natural gas production, scholars have yet to examine the communicative strategies used …

Maximizing Citizenship With Minimal Representation: An Analysis Of Afro-Argentine Civil Society Organizing Strategies, Prisca Suarez

USF Tampa Graduate Theses and Dissertations

This thesis examines the organizing strategies and successes of Afro-Argentine civil society organizations (CSO) in Buenos Aires. I argue that despite low representation, Afro-Argentines have strategically designed their initiatives in ways that draw on national discourses of identity rights and nationalism; and, as well, have used cultural inclusion to influence state actors, creating agency and increasing visibility. Afro-Argentines are a highly understudied population due to the common belief that they do not exist in Argentina as a group. This thesis not only dispels that myth with a history of the long hidden importance of Afro-Argentines contributions to the formation of …

Two Essays On Investor Distraction, Erdem Ucar

USF Tampa Graduate Theses and Dissertations

In theory, all relevant information is incorporated in stock prices timely and completely and therefore prices respond related news quickly in efficient financial markets. In today's information age, technological advances provide investors with fast access to a vast number of information resources. One can argue that these advances can help market efficiency due to easy and quick access to relevant information. On the other hand, these technological advances not only facilitate availability of relevant information but also facilitate availability of all types of information--both relevant and irrelevant information signals. In essence, one can argue that there is (over)exposure to information …

Time Scale Of Groundwater Recharge: A Generalized Modeling Technique, Makhan Virdi

USF Tampa Graduate Theses and Dissertations

Estimating the quantity of water that reaches the water table following an infiltration event is vital for modeling and management of water resources. Estimating the time scale of groundwater recharge after a rainfall event is difficult because of the dependence on nonlinear soil characteristics and variability in antecedent conditions. Modeling the flow of water through the variably saturated zone is computationally intensive since it requires simulation of Richards' equation, a nonlinear partial differential equation without a closed-form analytical solution, with parametric relationships that are difficult to approximate. Hence, regional scale coupled (surface water - groundwater) hydrological models make simplistic assumptions …

The Black Freedom Struggle And Civil Rights Labor Organizing In The Piedmont And Eastern North Carolina Tobacco Industry, Jennifer Wells

USF Tampa Graduate Theses and Dissertations

This thesis examines labor organizing in the U.S. South, specifically the Piedmont and eastern regions of North Carolina in the mid-twentieth century. It aims to uncover an often overlooked local history of civil rights labor organizing which challenged the southern status quo before America's 'mainstream' civil rights era of the 1950s and 1960s. This study argues that through labor organizing, African American tobacco workers challenged the class, gender, and race hierarchy of North Carolina's very profitable tobacco industry during the first half of the twentieth century. In doing so, the thesis contributes to the historiography of black working class protest, …

The Role Of Nature In Physiological Recovery From Stress: A Critical Examination Of Restorative Environments Theory, Kristi Elizabeth White

USF Tampa Graduate Theses and Dissertations

Recently, health researchers have become interested in "eco-friendly" or "green" healthcare. One of the current trends in the green healthcare movement involves incorporating natural elements into health care settings to promote the health of patients and healthcare workers. Research based on Restorative Environments Theory (RET) provides insight into the rationale behind incorporating nature into the healthcare setting. RET posits that pleasant natural environments help promote stress recovery by increasing positive affect, decreasing negative affect, and reducing physiological arousal. However, the components of this theory have not been sufficiently tested using a controlled laboratory environment. The purpose of the present study …

Effect Of Bolted Joint Preload On Structural Damping, Weiwei Xu

USF Tampa Graduate Theses and Dissertations

Bolted joints are integral parts of mechanical systems, and bolt preload loss is one of the major failure modes for bolted joint structures. Understanding the damping and frequency response to a varying preload in a single-bolted lap-joint structure can be very helpful in predicting and analyzing more complicated structures connected by these joints.

In this thesis, the relationship between the bolt preload and the natural frequency, and the relationship between the bolt preload and the structural damping, have both been investigated through impact hammer testing on a single-bolted lap-joint structure. The test data revealed that the bolt preload has nonlinear …

The Post- 9/11 Aesthetic: Repositioning The Zombie Film In The Horror Genre, Alan Edward Green, Jr.

USF Tampa Graduate Theses and Dissertations

This dissertation explores a body of films produced after the events of 9/11, and while examining this specific point of departure, the author presents the argument on the vast cultural relevancy of the omnipresent zombie. These films are interrogative and complex, offering the viewing audience a rich tapestry of interwoven meanings. Furthermore, the author suggests that the zombie trope has, in fact, left the genre altogether, reinserted into a style of films he labels as "non-zombie appropriation." Chapter 1 introduces the zombie genre as both part of the larger horror genre aesthetic and as its' own legitimate subgenre. The zombie …

The Influence Of Campus Culture On Mental Health Help-Seeking Intentions, Jason I. Chen

USF Tampa Graduate Theses and Dissertations

Mental health issues are widespread on college campuses. However, the majority of these individuals do not seek help. Prior research suggests many factors which may be related to mental health help-seeking including age, gender, and prior treatment experience. There has however been little work considering the context of the college campus on mental health help-seeking, specifically the influence of campus culture. Accounting for the context of mental health help-seeking may help to determine which social groups have the greatest influence on mental health treatment processes.

The purpose of this study was to explore the relationship between perceived peer, student body, …

The Assessment Of An In-Vitro Model For Evaluating The Role Of Parp In Ethanol-Mediated Hepatotoxicity, Jayme Coyle

USF Tampa Graduate Theses and Dissertations

This investigation assesses the role of poly(ADP-ribose) polymerase in ethanol-mediated hepatotoxicity using the untransfected HepG2 hepatocellular carcinoma line, an established, well-characterized toxicological model. HepG2 cells were treated with ethanol at concentrations between 100 mM and 800 mM, and assessed for markers of cytotoxicity. PARP-1 activity in total cell protein lysates was quantified as a proxy of apoptotic induction at six hours. Our results demonstrated a 1.43-fold AST activity increase in culture medium isolates of cells exposed to 800 mM without significant effect on cellular viability. PARP-1 activity varied greatly and results for enzyme activity remained inconclusive. The results suggest a …
