An Examination Of Diet, Acculturation And Risk Factors For Heart Disease Among Jamaican Immigrants, Carol Renee Oladele

USF Tampa Graduate Theses and Dissertations

Background: The South Florida region is home to over 85,000 Jamaican immigrants. Yet, little is known about the dietary intakes and predictors of risk of disease within this immigrant group. An assessment of dietary intakes and the development of dietary intake methodologies specific to the Jamaican population was important as it permitted accurate estimation of the nutrient intakes of this immigrant population whose dietary habits are not well documented. In addition, nothing is known about the prevalence of risk factors for heart disease or factors influencing risk factors among this immigrant group. The purpose of this study was to assess …

The Problem Of Evil In Augustine's Confessions, Edward Matusek

USF Tampa Graduate Theses and Dissertations

Augustine, the fourth-century Christian philosopher, is perhaps best-known for his spiritual autobiography Confessions. Two aspects of the problem of evil are arguably critical for comprehending his life in Books 1 through 9 of the work. His search for the nature and origin of evil in the various philosophies that he encounters (the intellectual aspect) and his struggles with his own weaknesses (the experiential aspect) are windows for understanding the actual dynamics of his sojourn.

I defend the idea above by providing a fuller examination of the key role that both aspects play in his spiritual journey. Examining relevant events from …

Explaining The "Female Victim Effect" In Capital Sentencing Decisions: A Case For Sex-Specific Models Of Capital Sentencing Research, Tara N. Richards

USF Tampa Graduate Theses and Dissertations

The potential influence of extralegal characteristics on the outcome of post-Furman capital cases (1972) has been a focus of criminal justice researchers and legal scholars. Much of this literature has assessed the impact of victim and defendant race on the likelihood of receiving the death penalty while a relatively underdeveloped body of research focuses on how victim sex may affect capital sentencing decisions. The present study uses focal concerns theory and the chivalry hypothesis to test the potential mediating effect of theoretical variables on the relationship between victim sex and juror capital sentence decision-making. In addition, it uses victim sex …

Comparative Life Cycle Assessments Of Lignocellulosic And Algae Biomass Conversion To Various Energy Products Through Different Pathways, Maria Juliana Pinilla

Bioenergy has the potential to reduce the world's dependence on fossil fuels, and to decrease the CO2 emissions due to fossil combustion. Lignocellulosic and algae biomass have been presented as promising feedstocks for bioenergy production.

In this study, a comparative Life Cycle Assessment (LCA) has been developed to evaluate the environmental impacts associated with different energy products via different routes across the whole life of algal and lignocellulosic bioenergy. Results were compared per energy basis, the production of 1 million BTU of energy products.

For the development of the comparative algae biomass conversion LCA, algal biomass was converted to liquid …

"Not If, But When": Sex, Risk, And Trust In Timing Gardasil Vaccine Decisions, An Exploratory Study Among Healthcare Providers And Middle-Class Parents In The U.S., Kathleen Marie Brelsford

USF Tampa Graduate Theses and Dissertations

This dissertation research explores how values regarding sexuality, morality, responsibility, protection, trust, and risk — expressed through parent, daughter, and healthcare provider relationships and interactions — inform parental decisions regarding the Gardasil® vaccine. In particular, the research examines the competing and conflicting meanings that parents and providers ascribe to vaccination and how actors position the vaccine within a wider set of negotiated, value–laden discourses. Because these narratives are situated within a larger structural field that shapes the landscape in which providers and parents interact, relevant historical and structural factors, including vaccine policy, cost, and compensation are discussed.

Prophylactic, Risk-Reducing Surgery In Unaffected Brca-Positive Women: Quality Of Life, Sexual Functioning And Psychological Well-Being, Sharon Tollin

USF Tampa Graduate Theses and Dissertations

Women with an inherited BRCA mutation are at significantly increased risk for breast and ovarian cancer, often diagnosed at an earlier age than sporadic cancers. Prophylactic surgery, with bilateral mastectomy and/or bilateral prophylactic salpingo-oophorectomy, represents an option for risk reduction. The purpose of this study was to explore quality of life, sexual functioning, menopausal symptoms, psychological well-being and satisfaction with risk management decisions for BRCA-positive women ages 21 to 50 (M = 38.4 years), without a personal history of cancer. A web-based, cross-sectional study design was utilized to compare women opting for any prophylactic surgery (n = 160) with those …

Cuban Medical Internationalism: A Case For International Solidarity In Foreign Policy Decision Making, Eric James Fiske

USF Tampa Graduate Theses and Dissertations

Since the beginning of the Revolutionary government in Cuba, a comprehensive foreign policy involving medical personal and equipment has been implemented worldwide. Known as medical internationalism, thousands of doctors have been sent to developed and less developed nations in the spirit of solidarity and humanitarian aid. Even more, thousands of students have been given free medical education in Cuba at its world renowned university, the Latin American School of Medicine (ELAM). Often, no monetary or direct political gain is made by Cuba and the doctors simply receive their normal government salary. While the success of Cuba's medical internationalism is well …

What Do Professional Conference Planners Consider The Most Important Elements For Continuing Professional Education Conference Planning?, Virginia B. Phillips

USF Tampa Graduate Theses and Dissertations

Many adults attend and rely on continuing professional education (CPE) throughout their careers, and CPE is big business for associations. One way associations deliver CPE is through educational conferences. While adult education theories and frameworks offer developmental and operational guidance and advice, there is little practice data to understand what meeting planning professionals actually do as they implement adult education conferences in practice. The purpose of this study was to identify the elements that practicing meeting planning professionals in associations utilize in CPE conference planning and which elements are considered the most important. This study accessed a senior group of …

Shaping Topographies Of Home: A Political Ecology Of Migration, Carylanna Kathryn Taylor

USF Tampa Graduate Theses and Dissertations

Even from afar, transnational migrants influence how their households and communities of origin use natural resources. This study depicts the circulation of people, funds, and ideas within transnational families that extend from a Honduran village to the United States. Developing a "political ecology of migration" approach, I show how these circulations can reshape resource use practices and the socio-economic and bio-physical topographies of emigrants' former homes. The project advances anthropological thought by linking rich literatures on political ecology and transnationalism through a multi-method ethnography of transnational families. The study is also relevant to emigrants, community members, and practitioners interested in …

Through purposeful sampling, eight prekindergarten special educators were identified because they held multiple teaching certifications and some held National Board certification. The participants had many years of experience in pre-kindergarten special education, and were professional development trainers, teacher mentors and or leaders in the prekindergarten special education community. These eight accomplished pre-kindergarten special education teachers were interviewed using an informal, semi-structured format about their beliefs concerning play, how they implement it in their classrooms as …

Prospects For Political Reform In China, Jody Lee Tomlin

USF Tampa Graduate Theses and Dissertations

This study is intended to analyze levels of institutional confidence in China. The purpose is to measure the relationship between changing political and cultural values with modernization and levels of institutional criticism. To analyze institutional criticism modernization and political culture theories are used. Using these theories together offers explanatory power as to what political and cultural values may change and why changes in confidence in governance may occur. These theories include socioeconomic, traditional, and political values to measure institutional confidence in 1990 and 2007. The examination of traditional versus modernization values imply that individuals possessing these opposing values display different …

Accuracy Of Educator Nominations In Identifying Students With Elevated Levels Of Anxiety And Depression, Jennifer Cunningham

USF Tampa Graduate Theses and Dissertations

Internalizing disorders, specifically depression and anxiety, affect up to 18% and 33% of youth, respectively (Costello, Egger, & Angold, 2005b). Schools have become a major provider of mental health services to children, primarily in attempts to overcome barriers to receiving community services (Farmer, Burns, Philip, Angold, & Costello, 2003). As such, it is important that schools have effective mechanisms in place to accurately identify students who may be in need of such services. The current study examined the accuracy of one such method, educator nominations (including from both teachers and school-based mental health professionals) in identifying students who self-report elevated …

The Role Of Male Partners In Childbirth Decision Making: A Qualitative Exploration With First-Time Parenting Couples, Sharon Dejoy

USF Tampa Graduate Theses and Dissertations

Fathers' attendance at childbirth is almost universal in the United States, but few researchers have addressed the role that males play in childbirth decision making. The number of technological interventions available to birthing women is increasing, as is the utilization of those interventions. The degree to which women choose or agree to these interventions plays a major role in individual and societal health outcomes. Therefore, health care policy makers and educators must find ways to help childbearing couples navigate the complex maze of decisions related to childbirth. However, policies and programs to increase shared decision making may not function as …

The Holistic Complementary Structure Of Western Bio-Medicine And Traditional Healing And Achieving Complete Health, Candace Gail Oubre

USF Tampa Graduate Theses and Dissertations

Achieving complete health requires a deep understanding of complementary cultural competency sensitivity between physician and patient. This may include but is not limited to access to preventative health care resources, access to health educational resources and access to cultural healing resources, for example, shamans, Ayurvedic physicians, and herbal healers. Advocates of cultural competency emphasize great importance on knowledge of the patients' cultural background; however, the transcendence of this knowledge can be explained further through complementary cultural competency sensitivity. This is when the cultures of the physician and patient complement each other in terms of understanding what is in the patients' …

Emotional Reactivity And Regulation In Current And Remitted Depression: An Event Related Potential Study, Lauren M. Bylsma

USF Tampa Graduate Theses and Dissertations

Major Depressive Disorder (MDD) is thought to be characterized by emotion regulation deficits, including decreased use of adaptive strategies such as reappraisal, but little is known about the exact nature of these deficits and whether or not they are specific to the depressed mood state. The late positive potential (LPP) is a sustained positive deflection of the event-related potential (ERP) associated with responding to emotionally-valenced stimuli, and reappraisal strategies have been found to reduce LPP magnitude in response to emotional stimuli in healthy individuals, but this effect has not been examined in MDD. This study utilized ERPs to examine emotional …

Characterization Of The Serologic Responses To Plasmodium Vivax Dbpii Variants Among Inhabitants Of Pursat Province, Cambodia, Samantha Jones Barnes

USF Tampa Graduate Theses and Dissertations

The Plasmodium vivax Duffy Binding Protein (DBP) is the ligand in the major pathway for P. vivax invasion of human reticulocytes, making it an appealing vaccine candidate. Region II of DBP (DBP-RII) is the minimal portion of the ligand that mediates recognition of the Duffy Antigen Receptor for Chemokines (DARC receptor) on the reticulocyte surface and constitutes the primary vaccine target. Analysis of natural variation in the coding sequences of DBP-RII revealed signature evidence for selective pressure driving variation in the residues of the putative receptor-binding site. We hypothesize that anti-DBP immunity in P. vivax infections is strain-specific and hindered …

Discovery Of A Functional Ecdysone Response Element In Brugia Malayi, Tracy Enright

USF Tampa Graduate Theses and Dissertations

The aim of this study was to determine whether functional ecdysone response elements (EcREs) exist within the genome of Brugia malayi, a parasitic nematode that causes lymphatic filariasis. The hypothesis that EcREs exist in B. malayi stemmed from previous demonstration of a functional ecdysone response system in B. malayi (Tzertzinis et al., 2010). Real-time PCR (qPCR) experiments were conducted to measure gene expression levels for twelve genes proximal to five putative EcREs in 20-OH ecdysone treated and untreated B. malayi embryos. Seven genes showed consistent upregulation with 20-OH ecdysone treatment. Each of the five putative EcREs had at least one …

A Retrospective And Prospective Comparison Of Hungarian Children Who Have One Or Two Episodes Of Depression, Vanessa Panaite

USF Tampa Graduate Theses and Dissertations

Early onset depression is associated with high recurrence rates later in life. Recurrent depressive episodes during childhood may be particularly problematic, if additional episodes have a scarring effect that hinders healthy development. Distinguishing between first onsets and recurrences has been useful in understanding adult depression. This distinction has seldom been examined in pediatric depression, in part because it is difficult to enroll adequate samples of children with recurrent depression. We conducted archival analyses of carefully-diagnosed pediatric probands with depression first onset between ages of 4 and 12. Probands who reported one depressive episode (N = 435) were compared with probands …

Aging With Independence And Interaction: An Assisted Living Community, Steven J. Flositz

USF Tampa Graduate Theses and Dissertations

As the U.S. population gets older, there is an increased need for senior housing. However, elderly housing is currently associated with dependence and isolation. There is a great disconnect from the retired community with its surrounding context. Senior housing and nursing homes are becoming more similar to miniature hospitals rather than a residential type. This negative view of nursing homes is becoming clear to the general population. In fact, most seniors fear the idea of living within an aging complex. Also, people generally avoid these places, even while visiting family. Florida is on the frontline for the effects of the …

An Observation Of Immunological Effect, A Diet Enhanced With Spirulina And Treatment With Fractalkine In Models Of Parkinson's Disease, Mibel M. Pabón

USF Tampa Graduate Theses and Dissertations

In my dissertation research we used use human wild type α-synuclein gene expression using an adeno-associated viral vector (AAV9) that induced a slowly progressive loss of dopamine (DA) neurons in the Substantia nigra (SN) as one of our animal model of Parkinson’s disease (PD). It is our hypothesis that neuroinflammation predisposes the brain to susceptibility to neurodegenerative diseases. Thus we examined the progression of a PD lesion and examined the manipulations of the immune system to understand further the inflammatory role when we administered exogenous soluble fractalkine.

The specific etiology of neurodegeneration in PD is unknown, but the inflammatory mechanisms …

Evaluation Of Preference For Exergames Among Elementary Students, Christie Ann Cacioppo

USF Tampa Graduate Theses and Dissertations

Obesity in children is a nationwide problem. Physical activity is one way to help children stay fit and prevent obesity. Unfortunately, access to technology involving sedentary behavior is easier than ever. Fortunately, for this generation of students there is a way to combine physical activity and technology through exergaming. In order to encourage students to participate in exergaming, the students should be able to play games they prefer. The purpose of this study was to apply a paired choice preference assessment, rank order card sort, and social validity surveys to determine the preference order of six exergames for six elementary …

Modeling And Surveillance Of Pandemic Influenza Outbreaks, Diana Prieto

USF Tampa Graduate Theses and Dissertations

Pandemic outbreaks are unpredictable as to their virus strain, transmissibility, and impact on our quality of life. Hence, the decision support models for mitigation of pandemic outbreaks must be user-friendly and operational, and also incorporate valid estimates of disease transmissibility and severity. This dissertation research is aimed at 1) reviewing the existing pandemic simulation models to identify their implementation gaps with regard to usability and operability, and suggesting research remedies, 2) increasing operability of simulation models by calibrating them via an epidemiological model that estimates infection probabilities using viral shedding profiles of concurrent pandemic and seasonal influenza, and 3) developing …

Cap-And-Trade Modeling And Analysis For Electric Power Generation Systems, Patricio Rocha

USF Tampa Graduate Theses and Dissertations

Cap-and-trade is the most discussed CO₂ emissions control scheme in the U.S. It is a market-based mechanism that has been used previously to successfully reduce the levels of SO₂ and NO_x emitted by power generators. Since electricity generators are responsible for about 40% of the CO₂ emissions in the U.S., the implementation of CO₂ cap-and-trade will have a significant impact on electric power generation systems. In particular, cap-and-trade will influence the investment decisions made by power generators. These decisions in turn, will affect electricity prices and demand. If the allowances (or emission permits) created by …

Utilizing Probabilistic Reinforcement To Enhance Participation In Parent Training, Errity Jones

USF Tampa Graduate Theses and Dissertations

Parental participation in parent training programs is necessary for success in behavioral parent training. Prior literature has demonstrated probabilistic reinforcement as an effective intervention for improving a wide variety of behaviors. In the present study, a probabilistic reinforcement program (i.e., lottery) was implemented in order to evaluate its efficacy as part of a behavioral parent training program. The behaviors targeted for increase included attendance, participation, homework completion, and performing role-plays or completing in-class assignments for two 10 week Tools for Positive Behavior Change courses. Participants earned lottery tickets for each of the dependent measures, and drawings took place at the …

General Strain Theory, Race, And Delinquency, Jennifer Peck

USF Tampa Graduate Theses and Dissertations

The present study drew on Agnew's General Strain Theory (GST) to examine the relationship between strain, race, and delinquent behavior. To address this possible association, five hypotheses were tested to examine if different types of strain and stress exposure influence delinquent coping and if these relationships are conditioned by race and ethnicity. Using data from the Add Health Study, White, African American, and Hispanic adolescents, the present study attempts to generalize GST to different racial and ethnic groups.

Results from OLS and negative binomial regression analyses indicate that some support was found for GST, in that indicators of strain to …

Approaches To Arc Flash Hazard Mitigation In 600 Volt Power Systems, Curtis Thomas Latzo

USF Tampa Graduate Theses and Dissertations

Federal regulations have recognized that arc flash hazards are a critical source of potential injury. As a consequence, in order to work on some electrical equipment, the energy source must be completely shut-down. However, power distribution systems in mission critical facilities such as hospitals and data centers must sometimes remain energized while being maintained. In recent years the Arc Flash Hazard Analysis has emerged as a power system tool that informs the qualified technician of the incident energy at the equipment to be maintained and recommends the proper protective equipment to wear. Due to codes, standards and historically acceptable design …

Making A Splash: Eliminating Water Phobia And Increasing Confident Water Skills, Paula Elizabeth Chan

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to utilize a multi-component intervention to increase confident water skills for three typically developing children, and to evaluate whether fearful behaviors decreased as the intervention progressed. The intervention, comprised of goal setting, self-monitoring, behavioral skills training and positive reinforcement, was used in community pools to teach basic water skills. Results suggest the intervention was successful in increasing confident water skills, while intervals with positive affect and fearful behaviors demonstrated variability.

Reducing Rapid Eating In Adults With An Intellectual Disability, Francia Echeverria

USF Tampa Graduate Theses and Dissertations

Rapid eating is a frequent problem among individuals with developmental disabilities that can pose a threat to health. The following study sought to reduce the rate of eating behaviors in two adults diagnosed with moderate intellectual disability. Assessment of eating rate took place in the participants' group homes during lunch or dinner meals. Procedures included the use of vibrating pagers with and without verbal prompts to prompt eating and prevent rapid eating behaviors. Results demonstrate a clear reduction in rate of eating when using vibrating pagers and verbal prompts for both participants.
