Aging Of Florida Blue Crabs, Callinectes Sapidus, Through The Biochemical Extraction Of Lipofuscin, Claire Elizabeth Crowley

USF Tampa Graduate Theses and Dissertations

The blue crab, Callinectes sapidus, represents an ecologically and economically important component of marine and estuarine ecosystems. In Florida, blue crab landings accounted for $9.6 million dollars during the 2010 fishing season. Accurate stock assessments for this valuable fishery are essential. Age is a critical biological component of accurate stock assessments; however, blue crabs and other crustaceans are especially difficult to age because of the complex nature of discrete growth. Biochemical extraction of an aging pigment, lipofuscin, was developed using blue crab eyestalks. The current study investigated the effects of freezing preservation on lipofuscin extracts and examined whether the …

Engineering Of A Knowledge Management System For Relational Medical Diagnosis, Maria Carolina Herrera-Hernandez

USF Tampa Graduate Theses and Dissertations

The increasingly high costs of health care in the U.S. have led the general public to search for different medical approaches. Since the 1990's, the use of Complementary and Alternative Medicine (CAM) has radically increased in the U.S. due to its approach to treat physical, mental, and emotional causes of illness. In 2009, the National Health Statistics reported the impact of CAM in the U.S. health care economy, with population expenditures of $14.8 billion out-of-pocket on natural Medicine and $12.4 billion out-of-pocket on visits to CAM providers as a complement to Western Medicine care.

CAM interconnects human functions to reach …

Inside Nfl Marriages: A Seven Year Ethnographic Study Of Love And Marriage In Professional Football, Rachel Anne Binns Terrill

USF Tampa Graduate Theses and Dissertations

When women marry NFL players and subsequently become NFL wives, they are thrust out of the lives they have known and into a form of secondary socialization among other NFL wives. In this dissertation, I use ethnography and narrative inquiry, the first- person narratives of four NFL wives, interactive interviews with dozens of NFL wives, friendship as method, and my personal autoethnographic experiences to describe the social interactions between NFL wives, the themes of their marriages, and the trajectories of their identity formation and transformation of NFL wives during their time in the league.

I also use autoethnography and writing …

A Novel Device And Nanoparticle-Based Approach For Improving Diagnosis And Treatment Of Pelvic Inflammatory Disease, Natasha Faith Cover

USF Tampa Graduate Theses and Dissertations

Pelvic Inflammatory Disease (PID) is one of the most common causes of morbidity in women. PID is a polymicrobial infection of the female reproductive tract, and is associated with pelvic pain, abnormal uterine bleeding, and tubal damage that can lead to ectopic pregnancies and infertility. It is curable but the effects of PID can be permanent if not properly diagnosed and treated. PID presents as a spectrum of disease and is often missed at early stages; even acute PID can be difficult to diagnose, as there is no single conclusive diagnostic test. Currently, PID is identified and treated syndromically because …

The Interrelationships Among Family Stress, Parenting Behavior, And Behavior Problems: An Investigation Of Internationally Adopted Chinese Girls, Cheryl Gelley

USF Tampa Graduate Theses and Dissertations

Although there have been many studies investigating international adoptees' outcomes in relation to their pre-adoption experiences, there is a paucity of research investigating the influence of post-adoption experiences. Guided by the proximity of the family to the child in Bronfenbrenner's (1979) ecological systems theory of human development, this study addressed a gap in the literature by investigating the interrelationships among family-related variables (e.g., stress in family environment, parenting behavior) and 648 internationally adopted Chinese girls' behavior problems. Moderate, positive relationships were found between family stress and both internalizing (r = .43, p < .001) and externalizing (r = .59, p < .001) behavior problems. Modest, inverse relationships were found between authoritative parenting and both internalizing (r = -.08, p < .01) and externalizing (r = -.15, p < .001) behavior problems. Additionally, modest to moderate, positive relationships were found between authoritarian and permissive parenting and internalizing (r = .18, p < .001; r = .19, p < .001, respectively) and externalizing (r = .39, p < .001; r = .34, p < .001, respectively) behavior problems. Finally, authoritarian and permissive parenting behaviors were partial mediators between family stress and both internalizing (R² = .08, p < .001; R² = .08, p …

Multisensory Integration In Shark Feeding Behavior, Jayne M. Gardiner

USF Tampa Graduate Theses and Dissertations

Multimodal sensory input directs simple and complex behaviors in animals. Most research to date has been limited to studies of individual senses rather than multiple senses working together, leading to important advances in our comprehension of the sensory systems in isolation, but not their complementary and alternative roles in difficult behavioral tasks, such as feeding. In the marine environment, a prey item might emit an odor, create a hydrodynamic disturbance, such as from gill movements or swimming, be visible to the predator, produce a sound, and/or produce a weak electrical field. Therefore, the goal of this study was to investigate …

The Relationships Between Individual Characteristics, Work Factors, And Emotional Labor Strategies In The Prediction Of Burnout Among Mental Health Service Providers, Jessica Belle Handelsman

USF Tampa Graduate Theses and Dissertations

Relatively few empirical studies in the professional burnout literature have examined mental health providers (MHPs). Research on other professional groups has demonstrated that certain emotion regulation strategies, known as emotional labor (i.e., deep acting and surface acting), are common responses to perceived display rules (i.e., professional guidelines for emotional expression), and are differentially associated with burnout. The present study aimed to fill a gap in the literature by evaluating the empirical links between work stressors (i.e., role conflict, role ambiguity, and lack of autonomy), personality (i.e., extraversion), emotional labor (i.e., surface acting and deep acting), and burnout in a sample …

Spatial And Temporal Variations In The Air-Sea Carbon Dioxide Fluxes Of Florida Bay, Christopher Michael Dufore

USF Tampa Graduate Theses and Dissertations

The flux of CO2 between the ocean and the atmosphere is an important measure in determining local, global, and regional, as well as short term and long term carbon budgets. In this study, air-sea CO2 fluxes measured using a floating chamber were used to examine the spatial and temporal variability of CO2 fluxes in Florida Bay. Measurements of dissolved inorganic carbon and total alkalinity obtained concurrently with chamber measurements of CO2 flux allowed calculation of ΔpCO2 from flux measurements obtained at zero wind velocity. Floating chamber measurements of ΔpCO2 were subsequently coupled with wind speed data to provide a simple …

Store-Operated Calcium Channels In The Function Of Intracardiac Neurons, Timetria Bonds

USF Tampa Graduate Theses and Dissertations

Proper autonomic regulation of mammalian cardiac function is dependent upon very complex and precise communication among the intracardiac ganglia and individual neurons within the ganglia. An array of neuromodulators is found within the ganglia that direct neuronal activity by modulating the movement of calcium. The current study determines that opioidergic agonists, which have been found to contribute to severe cardiac disease states and intracellular calcium mobilization, are also responsible for changes in the function of the intracardiac neuron via their effects on store-operated calcium channels (SOCs).

Previous studies suggest that phosphorylation plays a role in SOC regulation. Using Fura-2 calcium …

Determination Of Isotherms Of Enantiomers On A Chiral Stationary Phase Using Supercritical Fluid Chromatography, Wade Newlin Mack Ii

USF Tampa Graduate Theses and Dissertations

Supercritical fluids provide a robust, tunable environment with favorable transport properties and enhanced solubility. Supercritical carbon dioxide is an environmentally friendly substance that has distinct advantages to traditional solvents used in large scale chemical processing. Ibuprofen is an enantiomeric drug that has been shown to fight prostate cancer and has been used as a mild Alzheimer's disease treatment in the S conformation. Purification of high value products with decreased hazardous material consumption is accomplished by employing supercritical fluid chromatography (SFC). Large scale, single enantiomer purification of pharmaceuticals is dependent on scale-up information. Equilibrium isotherms provide the necessary information to scale-up …

The Invasive Cactus Moth, Cactoblastis Cactorum: Host Plant Testing, Species Interactions, And Effects On Local Opuntia Populations, Heather Jezorek

USF Tampa Graduate Theses and Dissertations

The invasive cactus moth, Cactoblastis cactorum, poses a threat to opunitoid cacti species of North America. The following work contains four separate studies investigating C. cactorum host plant preference and performance, predation and parastitism of C. cactorum, effects of C. cactorum on local Opuntia populations, and associational effects of host and non-host plants on C. cactorum and native Opuntia-feeding herbivores. We found that, among southwestern and Mexican opuntioid taxa, moths preferred O. engelmannii var. linguiformis and var. engelmannii for oviposition, while Consolea rubescens and O. streptacantha were superior larval hosts. Oviposition was best predicted by number of cladodes and degree …

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 …

Biochemical And Pharmacological Characterization Of Cytochrome B5 Reductase As A Potential Novel Therapeutic Target In Candida Albicans, Mary Jolene Patricia Holloway

USF Tampa Graduate Theses and Dissertations

The opportunistic fungus Candida albicans is a commensal member of the human microflora and is the most common causative agent of fungal-related disease with particular significance in immunocompromised individuals. Emerging drug resistance is a major problem in Candida, contributed by enzymes involved in the detoxification of xenobiotics and pharmacological agents. One such enzyme, cytochrome b5 reductase (cb5r), has a high pharmacological significance owing to its role in fatty acid elongation, ergosterol (or cholesterol in mammals) biosynthesis, and cytochrome P450-mediated detoxification of xenobiotics.

We have compared the kinetic, biochemical, and pharmacological characteristics of C. albicans cb5r isoforms, Cbr1 and Mcr1, as …

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

USF Tampa Graduate Theses and Dissertations

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 …

Religion As Aesthetic Creation: Ritual And Belief In William Butler Yeats And Aleister Crowley, Amy M. Clanton

USF Tampa Graduate Theses and Dissertations

William Butler Yeats and Aleister Crowley created literary works intending them to comprise religious systems, thus negotiating the often-conflicting roles of religion and modern art and literature. Both men credited Percy Bysshe Shelley as a major influence, and Shelley's ideas of art as religion may have shaped their pursuit to create working religions from their art. This study analyzes the beliefs, prophetic practices, myths, rituals, and invocations found in their literature, focusing particularly on Yeats's Supernatural Songs, Celtic Mysteries, and Island of Statues, and Crowley's "Philosopher's Progress," "Garden of Janus," Rites of Eleusis, and "Hymn to Pan." While anthropological definitions …

Teacher's Perception Of Their Principal's Leadership Style And The Effects On Student Achievement In Improving And Non-Improving Schools, Brenda Kay Hardman

USF Tampa Graduate Theses and Dissertations

Teachers' perceptions of their school leaders influence student achievement in their schools. The extent of this influence is examined in this study. This quantitative study examined teachers' perceptions of the leadership style of their principals as transformational, transactional or passive-avoidant in improving and non-improving schools in relation to student achievement. The study population was a purposeful sample of 143 teachers in 16 schools in one school district. Leadership behaviors, as perceived by the teachers, were measured using the Multi-factor Leadership Questionnaire. Student achievement was measured with the Florida Comprehensive Assessment Test results for each school using three years of results. …

"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.

Identification Of Novel Stat3 Target Genes Associated With Oncogenesis, Rachel Haviland

USF Tampa Graduate Theses and Dissertations

Cytokine and growth factor signaling pathways involving STAT3 are frequently constitutively activated in many human primary tumors, and are known for the transcriptional role they play in controlling cell growth and cell cycle progression. However, the extent of STAT3's reach on transcriptional control of the genome as a whole remains an important question. We predicted that this persistent STAT3 signaling affects a wide variety of cellular functions, many of which still remain to be characterized.

We took a broad approach to identify novel STAT3 regulated genes by examining changes in the genome-wide gene expression profile by microarray, using cells expressing …

A Sociocultural-Theory-Based Study Of The Impact Of Mediation During Post-Observation Conferences On Language Teacher Learning, Jane Harvey

USF Tampa Graduate Theses and Dissertations

The post-observation conference offers a potentially fecund context for promoting language teacher learning, but very little research has been conducted into how this actually happens. Taking Vygotskian sociocultural theory as its theoretical framework, this study examined the mediational discourse of a series of post-observation conferences between a mentor and two practicing English language teachers to investigate the nature of the discourse and the relationship between the mediational discourse and the language teachers` learning. Features of mediational discourse identified a priori (such as intersubjectivity, graduated and contingent help, and externalization of reasoning) were present in the data, but were found to …

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 …

Investigating The Role Of The Internet In Women And Minority Stem Participation: A Case Study Of Two Florida Engineering Programs, Arland Nguema Ndong

USF Tampa Graduate Theses and Dissertations

Despite our awareness of the fascination modern humans have with the Internet, little is known about how and why colleges and universities create and maintain Websites. At the most general level, in this case study, I hypothesize that university Websites serve as communication and marketing tools in attracting students. At the most specific level, I postulate that civil engineering programs with Web pages depicting images of women and minorities would be more successful in recruiting and retaining women and students of color than civil engineering programs with Web pages displaying fewer or no images of women and minorities. The primary …

From Cosmogony To Anthropogony: Inscribing Bodies In Vedic Cosmogony And Samskara Rituals, Christine Boulos

USF Tampa Graduate Theses and Dissertations

This thesis argues that the inscription of bodies is necessary in order to constitute the cosmos, gender and sex. A study of the Vedic cosmogonic mythologies of the deities Purusha and Prajapati illustrates the ways in which sacrifice, as a form of inscription, constitutes the cosmos by ordering and fashioning the boundaries of the bodies of the deities through differentiation and unification. An analysis of samskaras, or consecratory rites of The Law Code of Manu, show that they operate as regulatory norms in order to constitute sex and gender. But the instability and unnaturalness of the categories of gender and …

Sorting Through The Junk Box: Dickens's Objects And The Great Exhibition Of 1851, Audrey Raymi Grounds

USF Tampa Graduate Theses and Dissertations

In Bleak House , Dickens satirizes contemporary conditions in London in order to diagnose what he sees as social and industrial ills to prescribe a solution to the "Condition-of-England" question. Beginning with a review of the topicality in the novel, I use Dickens's personal letters, the text of Bleak House , and articles from Household Words to explain his contempt with the Great Exhibition, misguided philanthropy, and sanitary conditions, among others. Ultimately, it is his anathema to the Great Exhibition which drives both Dickens's plot and the issues he explores. Dickens's mockery of England is refracted and emphasized through his …

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 …

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 …

The Maghreb Maquiladora: Gender, Labor, And Socio-Economic Power In A Tunisian Export Processing Zone, Claire Therese Oueslati-Porter

USF Tampa Graduate Theses and Dissertations

This study is about Tunisian women's work and lives in the present era of economic neoliberalism. The focus is women in the city of Bizerte, Tunisia, both those who work in Bizerte's export processing zone (EPZ), as well as those who work outside it. This study is a qualitative examination of formal and informal employment, set inside and outside of women's traditional political and economic domain, the home. Through ethnography of women's work and lives, this study's purpose is to contribute evidence against conflating women's "empowerment" with incorporation into global production. However, this study also lends itself to considerations 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 …
