An Empirical Analysis Of Health Implications And Costs Of Obesity In Appalachia, Saman Janaranjana Herath Bandara

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obesity is a major health problem in the United States (U.S.) and approximately 34 percent of the U.S. adult population is obese. Studies using the Behavioral Risk Factor Surveillance System (BRFSS), the National Health and Nutrition Examination Survey (NHANES), and many other research findings warn that if the current trend of obesity continues, 50 percent of the U.S. population will be obese in 2030. Unfortunately, several diseases, such as heart disease, diabetes (type II), hypertension, cancer, arthritis, asthma, and some psychological disorders are linked with obesity. Obesity increases the risk of premature mortality, and nearly 300,000 annual deaths are associated …

Sensory Characteristics And Storage Quality Indicators Of Surimi Franks Nutritionally Enhanced With Omega-3 Rich Flaxseed Oil And Salmon Oil, Christin Rose Sell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Surimi, a lean source of fish protein, is consumed worldwide in various forms. Considerable increase in U.S. consumption of surimi products was observed in the 1980s but tapered off in recent decades. Consumer demand for foods enriched with o-3 fatty acids including DHA and EPA has increased due to potential health benefits. Therefore, the purpose of this study was to (1) create a surimi frank enhanced with o-3 PUFA rich salmon oil or flaxseed oil, (2) evaluate product composition and quality indicators (pH, color {lcub}L*, a*, b*{rcub}, syneresis, thiobarbituric acid reactive substances test, and texture) over 21d, and (3) establish …

Health Literacy And Self-Efficacy As Correlates Of Self-Management Of Type 2 Diabetes In Middle-Aged And Older Adults, Tomorrow D. Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The prevalence of type 2 diabetes is increasing with middle-aged and older adults being those at highest risk for developing this disease. Additionally, the demands of type 2 diabetes self-management can become difficult with age, which can result in poorer glycemic control. The current study examined the relations of health literacy, diabetes-related distress, and diabetes self-efficacy on diabetes self-management among 65 adults aged 40-66 with type 2 diabetes. Age was found to be positively associated with health literacy, but negatively associated with diabetes self-care activities. Additionally, only diabetes self-efficacy was found to be a unique contributor to diabetes self-care activities …

Assessing Dementia In Resource-Poor Regions, Gladys E. Maestre

School of Medicine Publications

The numbers and proportions of elderly are increasing rapidly in developing countries, where prevalence of dementia is often high. Providing cost-effective services for dementia sufferers and their caregivers in these resourcepoor regions poses numerous challenges; developing resources for diagnosis must be the first step. Capacity building for diagnosis involves training and education of healthcare providers, as well as the general public, development of infrastructure, and resolution of economic and ethical issues. Recent progress in some low-to-middle-income countries (LMICs) provides evidence that partnerships between wealthy and resource-poor countries, and between developing countries, can improve diagnostic capabilities. Without the involvement of the …

Peripheral (Limb) Myokymic Discharges In Motor Neuron Disease, Javeria Rauf, Junaid Akhtar, Bhojo Assumal Khealani, Liaquat Ali

Section of Neurology

We present the case of a 28-year-old gentleman who presented with weakness and wasting in the right arm. He complained about painful cramps in his left leg but there were no sensory, visual or swallowing problems. Neurological examination was significant for asymmetric weakness of both upper and lower limbs and deep tendon reflexes were asymmetrically brisk. Initial laboratory investigations, MRI brain and MRI spine were normal. Electromyography revealed active denervation and chronic neurogenic motor unit action potential. Myokymic discharges were noted in the left deltoid muscle.

Consequences Of Kleptoplasty On The Distribution, Ecology, And Behavior Of The Sacoglossan Sea Slug, Elysia Clarki, Michael Louis Middlebrooks

USF Tampa Graduate Theses and Dissertations

The sacoglossan sea slug Elysia clarki is able to photosynthesize for three to four months using chloroplasts sequestered from its algal food sources. Furthermore, the slug is able to store multiple chloroplasts from different algal species within the same cell. This research, consisting of several related studies, explores the role that provision of organic nutrients via photosynthesis plays in the biology of the slug. The first chapter demonstrates that, under conditions of starvation, photosynthetic activity in E. clarki remains fully functional for one month after which it then declines. During the first month of starvation the slug exhibits similar feeding …

Modification Of Trophic Links Between An Omnivore And Macroinfaunal Prey From Sandy Beaches Of Differing Physical Regimes, Kristina Joan Morrow

USF Tampa Graduate Theses and Dissertations

Sandy beach ecosystems have been studied worldwide; however, ecological data are sparse for the extensive barrier islands of Florida. Accordingly, I investigated the feeding patterns of the ghost crab (Ocypode quadrata), a dominant omnivore inhabiting beaches along the Floridian coast. Density data was collected for ghost crabs and swash macroinfaunal prey. In addition, I utilized stable isotopes in conjunction with the mixing models IsoSource and SIAR to characterize diets of ghost crabs across three barrier islands in spring and summer 2011. Results showed that ghost crabs at Cayo Costa feed primarily on swash macroinfauna, while those from Anclote Key shifted …

The Yellow Flag Of Quarantine: An Analysis Of The Historical And Prospective Impacts Of Socio-Legal Controls Over Contagion, Peter Oliver Okin

USF Tampa Graduate Theses and Dissertations

Under the ancient threat of morbidity and mortality from infectious diseases, human societies have responded for thousands of years by imposing social containment measures. Even before theorists and laymen recognized the existence of pathogenic organisms, or fully understood the principles of contagion, many societies and individuals did empirically infer that such diseases were transmissible from human to human (as well as sometimes between animals and humans). Having few effective technological measures to prevent or treat contagions, they did devise a variety of socio-behavioral procedures for separating overtly ill persons or suspected disease-carriers from nominally uninfected people. These methods included various …

Occupational Stressors Among Providers Of Hiv Prevention And Support Services, Mackenzie Kaye Rapp

USF Tampa Graduate Theses and Dissertations

Much literature has documented the high levels of burnout, stress, and grief in HIV physicians and nurses due to the challenging nature of the chronic, fatal disease with which they deal on a daily basis. Providers of social and HIV prevention services face similar challenges while working with stigmatized, terminally ill clients. However, since these latter occupations deal with social, rather than clinical interventions, their experiences may differ from those of medical personnel. Through open-ended interviews with HIV counselors, educators, case managers, and outreach workers, this exploratory study assesses the occupational stressors of providers of social and HIV prevention services …

Fit To Lead? Supervisors' Health Behaviors, Well-Being, And Leadership Behaviors, Kristin Saboe

USF Tampa Graduate Theses and Dissertations

This study proposes a model to test the relationships amongst supervisors' health behaviors and leadership behaviors. Specifically, 107 supervisor-subordinate pairs responded to a cross-sectional survey. Supervisors provided self-reports of their health behaviors (physical activity, diet, sleep, alcohol/tobacco use) and perceived well-being. Subordinates rated the supervisors' perceived leadership style and the quality of relationships they share at work. Results were mixed with support largely being found for previously established relationships between (a) physical activity, sleep duration and quality, and well-being, and (b) leadership behaviors and supervisor-subordinate relationship quality. The primary thesis of this study--that leaders with improved health behaviors and well-being …

Love And Risk: Intimate Relationships Among Female Sex Workers Who Inject Drugs And Their Non-Commercial Partners In Tijuana, Mexico, Jennifer L. Syvertsen

USF Tampa Graduate Theses and Dissertations

This dissertation examines the influence of love and other emotions on sexual and drug-related HIV risk among female sex workers who inject drugs and their intimate, non-commercial partners in Tijuana, Mexico. My work on a public health study along the Mexico-U.S. border and independent ethnographic research in Tijuana suggests the importance of emotions in shaping sex workers' relationships and health risks.

Love is a universal human emotional experience embodied within broader cultural, social, and economic contexts. A growing body of cross-cultural research suggests that modern relationships have transformed to emphasize love and emotional intimacy over moral or kinship obligations. Particularly …

An Interactive Guide To Self-Discovery For Women, Elaine J. Taylor

USF Tampa Graduate Theses and Dissertations

This project is a translation of ideas I have encountered in my journey through Women's Studies. With this interactive book, I offer a concise, understandable, and empowering method for self-discovery from one feminist's perspective. Traditional self-help materials often set the reader up as the one with the issue or problem and they rarely call out the functioning systems of oppression as a stumbling block or offer ways to circumvent them. With this project, I hope to shine light on the functioning systems of gender discrimination, racism, classism, and heterosexism, and to provide a framework for understanding. There are three main …

Therapeutic Peptide-Based Vaccination Strategies Against Hpv-Induced Cancers, Kelly Barrios Marrugo

USF Tampa Graduate Theses and Dissertations

There is an urgent need for the development of an effective therapeutic vaccine against cancer caused by human papilloma virus (HPV). We focused on HPV-induced malignancies because of their high worldwide prevalence (e.g., cervical carcinoma and head & neck cancer). A successful therapeutic vaccine could prevent the 250 000 deaths/year worldwide and the 2.25 billion dollars that

are expended in related care in the US.

We used an HPV-induced mouse cancer model to test vaccines

composed of a CD8 T cell peptide epitope administered with potent adjuvants designed to generate vast numbers of high avidity cytotoxic T lymphocytes specific for …

Good Men Grow Corn: Embodied Ecological Heritage And Health In A Belizean Mopan Community, Kristina Linda Baines

USF Tampa Graduate Theses and Dissertations

Recent developments in land rights and land use in the Toledo district, Belize has generated anthropological and activist interest surrounding traditional ecological knowledge and practice, and the role of heritage in communities. This study explores the connection between ecological knowledge and practices, and the concurrent construction of heritage, and community health and wellness, broadly defined. Developing and using the concept of "embodied ecological heritage," this dissertation takes a phenomenological approach to understanding the convergence of ecological heritage and health in multiple realms of everyday life, arguing that lived experience of participating in "traditional" practices is fundamentally connected to wellness in …

Stable Carbon Isotope Discrimination By Rubisco Enzymes Relevant To The Global Carbon Cycle, Amanda J. Boller

USF Tampa Graduate Theses and Dissertations

Five different forms of ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO; IA, IB, IC, ID, II), the carboxylase of the Calvin-Benson-Bassham cycle (CBB), are utilized by plants, algae and autotrophic bacteria for carbon fixation. Discrimination against ¹³C by RubisCO is a major factor dictating the stable carbon isotopic composition (δ¹³C = {[¹³C/¹²C sample/¹³C/¹²C standard] - 1} X 1000) of biomass. To date, isotope discrimination, expressed as ε values (={[¹²k/¹³k] - 1} X 1000; ¹²k and ¹³k …

The Effects Of Food Insecurity On Mental Wellbeing In Monteverde Costa Rica, Robert Eugene Cowherd

USF Tampa Graduate Theses and Dissertations

The rapid expansion of ecotourism in the Monteverde zone of Costa Rica has increased the incidence in food insecurity in the area. Changes in food preferences and availability have led to a more homogenized diet that is increasingly delocalized and reliant on processed foods. Additionally, there has been a rapid economic shift away from agricultural and dairy farming to an economy more reliant on tourism. This NSF supported study builds upon data from a longitudinal investigation (#BNS 0753017) examining the nutritional effects of this rapid economic transition. Using a mixed methods approach, a culturally appropriate scale of stress was developed …

Exploring The Advance Care Planning Experiences Among Persons With Mild Cognitive Impairment: Individual And Spousal Perspectives, Catherine Parsons Emmett

USF Tampa Graduate Theses and Dissertations

Advance Care Planning has been advocated for over 20 years as a way in which individuals who are no longer able to speak for themselves, may still convey their preferences regarding a wide of array of decisions, including medical care. Advance care planning may not be initiated by individuals for many reasons, and even when initiated, may not be specific enough to help guide decision making. Recent advance care planning models have utilized disease specific information to help guide end of life health care decision-making. Persons diagnosed with mild cognitive impairment face an increased possibility of developing dementia at some …

Tagline: Information Extraction For Semi-Structured Text Elements In Medical Progress Notes, Dezon K. Finch

USF Tampa Graduate Theses and Dissertations

Text analysis has become an important research activity in the Department of Veterans Affairs (VA). Statistical text mining and natural language processing have been shown to be very effective for extracting useful information from medical documents. However, neither of these techniques is effective at extracting the information stored in semi-structure text elements. A prototype system (TagLine) was developed as a method for extracting information from the semi-structured portions of text using machine learning. Features for the learning machine were suggested by prior work, as well as by examining the text, and selecting those attributes that help distinguish the various classes …

Stable Isotope Analysis Of Busycon Sinistrum To Determine Fort Walton-Period Seasonality At St. Joseph Bay, Northwest Florida, Ryan Michael Harke

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Recent archaeological investigations indicate that coastal Fort Walton cultures in the St. Joseph Bay region of northwest Florida emphasized marine and estuarine foraging. These late prehistoric (A.D. 1000-1500) peoples collected fish, shellfish, and other aquatic resources. At the Richardson's Hammock site (8Gu10), radiocarbon-dated to about A.D. 1300, as at dozens of other shell middens around this salty bay, large gastropods were a major subsistence component. This adaptation is in sharp contrast with that of contemporaneous inland Fort Walton societies, who relied on maize agriculture. It is unknown whether coastal groups represent separate hunter-gatherer-fisher populations or seasonal migrations by inland …

"People...Do Not Come With Standardized Circumstances": Toward A Model For An Anthropology Of E-Government, Marc K. Hebert

USF Tampa Graduate Theses and Dissertations

Many Americans appreciate the availability and ease of using government websites to conduct their business with the state. What then of the most vulnerable in society? How do they access and use a standardized application process for government assistance, considering their potential resource, educational and physical constraints? Many go to public libraries and non-governmental organizations (NGOs), which shifts the responsibility to help applicants from the government agency administering the program to local actors whose primary duties lie elsewhere.

The aim of this research is to document the experiences of three groups of people, primarily located in a central Florida, urban …
