Expectations Of Nursing Home Use, Psychosocial Characteristics And Race/Ethnicity: The Latino/A Case, Heidi Ross

USF Tampa Graduate Theses and Dissertations

This study used data from the 2008 wave of the Health and Retirement Study to examine variations in relationships among selected psychosocial characteristics, race/ethnicity and expectations of nursing home utilization in the United States, with a particular focus on Latino/a subgroups. This study sought to test a modified version of the Andersen and Newman model of health service utilization. Findings revealed that expectations of nursing home utilization remained lower among Latino/as than in the Non-Latino White sub-groups, even when levels of need, enabling, and predisposing factors were controlled for. However, for Mexican Origin respondents (who are often arbitrarily combined with …

Insight Into The Use, Perception, And Value Surrounding Domestic Water In Peru: Envisioning Demand Management In An Intermittent, Small-City, Service Context, Merril Augusta Putnam

USF Tampa Graduate Theses and Dissertations

Population growth, urbanization, degrading water quality, and climate change are making management of scarce water resources an increasingly difficult task for the domestic sector. It is recognized that in order to manage urban water resources demand management is requisite. Demand management has been experimented with in large cities of developing countries but continued focus on expanding supply overshadows its potential benefits and ultimate success. In order to manage demand, it must be measured and understood. Intermittent water services are prevalent in developing countries, but unmetered domestic water use under such conditions has not been carefully studied. This study conducted 1,149 …

A Collective Case Study Of The Diagnosis Of Dissociative Disorders In Children, Jacqueline J. Reycraft

USF Tampa Graduate Theses and Dissertations

There is a paucity of research on the diagnosis of dissociative disorders in children. Most children are misdiagnosed with more common mental disorders with similar symptoms. Earlier recognition of dissociative disorders can save years of pain, suffering, and cost. This qualitative collective case study examined the process of diagnosing dissociation in two children under the ages of 12 at the beginning of treatment. A concurrent focus on the training and development of the therapist/researcher is included. Archival data including progress notes, psychotherapy notes, assessments, correspondence, legal documents, school records, and medical records were analyzed using within-case and cross-case analyses to …

Beyond The Door: Disability And The Sibling Experience, Morgan Violeta Sanchez Taylor

USF Tampa Graduate Theses and Dissertations

This thesis explores the experiences of adult siblings of individuals with impairments. It expands on the existing literature by exploring the complexity of the sibling experience of disability while moving beyond the concepts of burden and maladjustment that have characterized much of the previous literature. In addition, it expands upon and extends to the sibling experience an emerging view of disability by examining the ways in which themes identified in sibling narratives cross lines between the Medical and Social Models of Disability. Building on work by Mark Priestly and Tom Shakespeare, I call this emerging view the Interactional Model of …

The Elimination Of Blindness: An Ethnographic Exploration Of The Fight Against Trachoma In Niger, Kelley Cosby Sams

USF Tampa Graduate Theses and Dissertations

The goal of this study is to explore specialized and popular cultural models of trachoma, and the interaction between the trachoma elimination program and its target audience in one trachoma hyper-endemic intervention community. Eighty four million people worldwide, mainly children, are infected with active bacterial trachoma. For some, this will lead to painful and progressive corneal opacity and eventual blindness. The disease is most commonly spread by person-to-person contact or by flies, and affects very specific populations living in resource-poor areas such as rural Niger, which has one of the highest prevalence rates worldwide.

USF Tampa Graduate Theses and Dissertations

The main purpose of this study was to analyze the role and potential of community arts programs and organizations in improving the lives of disadvantaged African American youth, through the creation of a participatory video project and the internal evaluation of the same; using applied anthropological methods, and cultural praxis (an innovative educational design), and following the recommendations of expert community arts programs evaluators. The study responds to the need identified in the community arts literature to offer robust program evaluations that explain the benefits of such programs. The lack of evidence seems to derive not only from the difficulties …

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 …

Strategic Messaging In A Political Crisis: Testing The Integrated Model For Explaining The Communication Behavior Of Publics, Tiffany Lynn Schweickart

USF Tampa Graduate Theses and Dissertations

Crisis response message strategies were examined using a post test-only randomized experiment (N=252) to determine their influence on perceptual, cognitive, and motivational antecedents to communication behavior in a political context. Results indicate that: (1) strategy type influences perceived strategy effectiveness; (2) situational beliefs influence situational motivation, subjective norm, and attitudes; (3) subjective norm and attitudes influence behavioral intention; and (4) referent criterion, situational motivation, and behavioral intention influence communicative action in publics during a political crisis.

Community And Household Management Strategies For Water Supply And Treatment In Rural And Peri-Urban Areas In The Developing World, Ryan William Schweitzer

USF Tampa Graduate Theses and Dissertations

Eighty percent of the 780 million people worldwide that access water from an unimproved source live in rural areas. In rural areas, water systems are often managed by community based organizations and many of these systems do not provide service at the designed levels. The Sustainability Analysis Tool developed in Chapter 2 can inform decision making, characterize specific needs of rural communities in the management of their water systems, and identify weaknesses in training regimes or support mechanisms. The framework was tested on 61 statistically representative geographically stratified sample communities with rural water systems in the Dominican Republic. The results …

The Inflammatory Response Initiated By The Spleen To Ischemic Stroke, Hilary Seifert

USF Tampa Graduate Theses and Dissertations

The peripheral immune system plays a role in delayed neural injury after stroke. This response originates from the spleen as splenectomy prior to middle cerebral artery occlusion (MCAO) in rats significantly reduces infarct volume in the brain. This research is based on the hypothesis that inhibiting the splenic response will reduce neurodegeneration after stroke. Studies in animals have implicated lymphocytes as the immune cell type that is detrimental following MCAO. Interferon gamma (IFNγ) has been identified as a pro-inflammatory cytokine that is also detrimental following stroke. IFNγ is important because it activates microglia and macrophages in a pro-inflammatory nature that …

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 …

Harmful Algal Blooms Of The West Florida Shelf And Campeche Bank: Visualization And Quantification Using Remote Sensing Methods, Inia Mariel Soto Ramos

USF Tampa Graduate Theses and Dissertations

Harmful Algal Blooms (HABs) in the Gulf of Mexico (GOM) are natural phenomena that can have negative impacts on marine ecosystems on which human health and the economy of some Gulf States depends. Many of the HABs in the GOM are dominated by the toxic dinoflagellate Karenia brevis. Non-toxic phytoplankton taxa such as Scrippsiella sp. also form intense blooms off the Mexican coast that result in massive fish mortality and economic losses, particularly as they may lead to anoxia.

The main objectives of this dissertation were to (1) evaluate and improve the techniques developed for detection of Karenia spp. blooms …

Knowledge, Attitudes And Traditions Regarding Water Consumption And Sanitary Practices Of The Ngäbe-Buglé Indigenous Women In The Chiriquí Province In Panama, Natalia Vega

USF Tampa Graduate Theses and Dissertations

Background: In 2007, approximately 66.2% of the population of the Comarcas (indigenous reservations) in Panama had access to potable water. However, over 50% of this population lacked access to sanitation. As a result, the leading causes of death in the Comarca Ngäbe-Buglé are due to severe diarrhea and gastroenteritis of infectious origin. The present project assessed the need for an in-depth understanding of the Ngäbe-Buglé women and their communities regarding their knowledge, attitudes, beliefs and behaviors about water and sanitation. Methodology: In this cross-sectional exploratory study, a convenience sample of 52 women were interviewed, utilizing a questionnaire guided by the …

Anti-Parasitic And Anti-Bacterial Agents: Studies On 1,4-Dihydropyridines And 2,4-Diaminoquinazolines, Kurt Steven Van Horn

USF Tampa Graduate Theses and Dissertations

Thirty-three 1,4-dihydropyridine diastereomeric pairs were synthesized and the structure-activity relationship studied in a Plasmodium falciparum in vitro model. Twenty-nine of these derivatives contained a 6-position oxygen, with 2.31, 2.32, 2.52 and 2.53 having single and double digit nanomolar activities. This SAR study revealed some insightful information about the 1,4-dihydropyridine substitution pattern. Substitution at the 7-position other than 3,4-dimethoxy severely reduced the activity. 4-phenyl substitution with 2- or 4- halo or methyl formed active compounds while substitution at the 3-position or with methoxy or conjugated aryl systems resulted in inactive compounds. The 2-position was found to majorly affect the activity, with …

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, …

Agricultural And Domestic Waste Contamination In Chilibre Panama And Potential Low-Cost Best Managament Practices, Christopher Etienne Weekes

USF Tampa Graduate Theses and Dissertations

Abstract

Sanitation coverage in the Republic of Panama is 5 to 10 percent below the Millennium Development Goals targets set for the country. Population growth, urbanization, unplanned development and waste mismanagement have resulted in improvised trash sites and waste discharges into river systems that are important components of the biologically diverse natural environment of Panama. The study sought to investigate and estimate the burden of waste from domestic and agricultural sources in three regions of the Chilibre corrigimiento (district). It was hypothesized that the water quality and land cover data would reflect that the most populated region in the study …

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 …

The Effectiveness Of A Structured Functiona Behavior Assessment Procedure: Teacher Training As A Moderator, Bonnie Woods

USF Tampa Graduate Theses and Dissertations

Prevent-Teach-Reinforce (PTR) is a collaborative, standardized process that was developed as a way to address identified barriers to completing effective functional behavior assessments (FBAs) in public schools. Current research literature documents the effectiveness of the PTR process in decreasing problematic behaviors and increasing social skills and academic engaged time for students in kindergarten through 8th grade. In addition, PTR demonstrates high acceptability by school personnel implementing the process. While PTR has demonstrated success in schools, questions still exist regarding variables that impact the effectiveness of this process. Therefore, the current study investigated the moderating effect of prior teacher training in …

Two Essays On Politics In Corporate Finance, Xiaojing Yuan

USF Tampa Graduate Theses and Dissertations

I examine how political geography affects firms' cost of debt. Policy risk, measured by proximity to political power reflected in firms' position in the country's political map, is negatively related to corporate bond ratings and positively related to firms' cost of debt. I find firms' policy risk can be mitigated by engaging in corporate political strategies like making campaign contributions or lobbying. Consistent with the view that such political strategies effectively protect firms against uncertainty about future policies, I find policy risk has less of an impact on the cost of debt of firms that support more powerful and well-connected …

A Modeling Investigation Of Human Exposure To Select Traffic-Related Air Pollutants In The Tampa Area: Spatiotemporal Distributions Of Concentrations, Social Distributions Of Exposures, And Impacts Of Urban Design On Both, Haofei Yu

USF Tampa Graduate Theses and Dissertations

Increasing vehicle dependence in the United States has resulted in substantial emissions of traffic-related air pollutants that contribute to the deterioration of urban air quality. Exposure to urban air pollutants trigger a number of public health concerns, including the potential of inequality of exposures and health effects among population subgroups. To better understand the impact of traffic-related pollutants on air quality, exposure, and exposure inequality, modeling methods that can appropriately characterize the spatiotemporally resolved concentration distributions of traffic-related pollutants need to be improved. These modeling methods can then be used to investigate the impacts of urban design and transportation management …

Preparing Teachers To Apply Research To Mathematics Teaching: Using Design-Based Research To Define And Assess The Process Of Evidence-Based Practice, Sarah Van Ingen

USF Tampa Graduate Theses and Dissertations

Persistent lack of mathematics achievement and disparity in achievement has led to the publication of research findings related to equitable teaching practices. Although the publication of such research provides insights about approaches for potentially increasing equity in mathematics education, teachers must be able to apply what has been learned from these studies to their classroom teaching practices. Despite the widespread expectation that teachers use research-supported teaching strategies to meet the needs of their diverse classrooms, the research to practice gap persists. Little research is currently available to guide mathematics teacher educators in how to prepare future teachers to apply research …

Cause-Related Controversy: An Analysis Of Corporate Sponsor Response To The Susan G. Komen/Planned Parenthood Crisis, Christina Maria Cameron

USF Tampa Graduate Theses and Dissertations

ABSTRACT

This qualitative study advances crisis communication and relationship management application and theory by examining the crisis response strategies used by corporations during a time of crisis involving a nonprofit partner. A qualitative content analysis was performed on the Facebook pages of 57 companies that were corporate partners of Susan G. Komen in early 2012. Nineteen companies responded using their Facebook accounts during two crisis periods studied. The researcher argues that consideration must be given to additional contingent factors beyond those proposed by situational crisis communication theory. Contingent variables related to the corporations' relationship with the charity, including level of …

Statistical Analysis And Modeling Of Prostate Cancer, Yiu Ming Chan

USF Tampa Graduate Theses and Dissertations

The objective of the present study is to address some important questions related to prostate cancer treatments and survivorship among White and African American men. It is commonly understood that the risk of developing prostate cancer is higher in African American men than the other races. However, using parametric analysis, this study demonstrates that this perception is a "myth" not a "reality". The study further identifies the existence of racial/ethnic disparities by comparing the average mean tumor size, the median of survival time, and the survival function between White and African American men. These results underline the necessity of understanding …

Prehispanic Water Management At Takalik Abaj, Guatemala, Alicia E. Alfaro

USF Tampa Graduate Theses and Dissertations

Land and water use at archaeological sites is a growing field of study within Mesoamerican archaeology. In Mesoamerica, similar to elsewhere in the world, landscapes were settled based partially upon the characteristics of the environment and the types of food and water resources available. Across Mesoamerica, landscape concepts were also important to religious beliefs and ritual activity in a manner that may have had the potential to influence the power dynamics of a site. This thesis focuses on the management of water at the site of Takalik Abaj in Guatemala during the Middle to Late Preclassic periods (c. 1000 B.C. …

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 …
