A Reflexive Approach To Capability Valuation And Determination In Sustainable Human Development: The 2010 Hillsborough County Transit Referendum, Eric James Fiske

USF Tampa Graduate Theses and Dissertations

Sustainable Human Development (SHD), rooted in Amartya Sen’s development theory on the capability approach, envisions achieving sustainable human capabilities at the local and global levels. One major area of contention within this field of research concerns determination and valuation of capabilities. How a community decides which capabilities should be developed is as important as the development itself. Some capability scholars argue that a small group of experts or “philosophers” should make this determination, while others argue that a deliberative democratic process needs to be followed. I seek to reconcile these two positions by introducing a third way of determining and …

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 …

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 …

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 …

"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.

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 …

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 …

USF Tampa Graduate Theses and Dissertations

This study examined Early Childhood Special Educators' perceptions of play as a developmentally appropriate practice in special education prekindergarten classrooms in one southeastern school district. 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 …

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 …

Quasi 3-Dimensional Electrical Resistivity Mapping Of Air-Filled Karst Conduits And Policy Implications, Charles W. Mccrackin

USF Tampa Graduate Theses and Dissertations

This study assesses the capability and practical applications of quasi 3-Dimensional (3D) electrical resistivity surveying (ER) for mapping air-filled karst conduits. Vadose zone caves within the Brooksville Ridge of West Central Florida are relatively similar in architecture, with N-S elongation, and do not consist of an interconnected network of conduits. A high resolution quasi-3D ER survey was performed over two mapped cave systems on the Brooksville Ridge. The resultant survey verified the general effectiveness of quasi-3D ER in locating the two known near-surface cave features. Several other locations in the survey show similar or stronger resistivity anomalies trending in a …

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 …

An Examination Of The Relationship Between Elementary Education Teacher Candidates' Authentic Assessments And Performance On The Professional Education Subtests On The Florida Teacher Certification Exam (Ftce), Thomas Raymond Lang Ii

USF Tampa Graduate Theses and Dissertations

Abstract

According to Wilkerson and Lang (2003, p.1) with approximately "90% of schools, colleges, and departments of education using portfolios of one form or another as decision-making tools for standards-based decisions regarding certification or licensure (as well as NCATE accreditation), it is appropriate to explore the legal and psychometric aspects of this assessment device."

This study was conducted to examine how well the authentic assessments created in the Chalk and Wire ePortfolio initiative, which was created to provide authentic assessments of the Accomplished Practices, relate to the measures in the Professional Knowledge subtests on Florida Teacher Certification Examination.

The sample …

Historical Archaeology Of The Pine Level Site (8de14), Desoto County, Florida, Jana Futch

USF Tampa Graduate Theses and Dissertations

In 1866 the seat of Manatee County was moved to Pine Level, a newly-formed town in the wilderness of south Florida. By the 1880s, it contained stores, boardinghouses, churches, and government buildings. In 1887, Pine Level became DeSoto County’s first seat. However, when it lost county seat status to Arcadia only 18 months later, in 1888, Pine Level rapidly declined in population and importance, and eventually died out. The investigations of the Pine Level site detailed in this thesis were carried out as a public archaeology project, involving the DeSoto County Historical Society, University of South Florida, and the Florida …

American Muslim Identities: A Qualitative Study Of Two Mosques In South Florida, Azka Mahmood Mahmood

USF Tampa Graduate Theses and Dissertations

Most existing research on Muslims and transnational Islam originates from Europe. However, the Muslim population in Europe differs from American Muslims in a number of important ways. In this research I aim to address the general paucity in sociological literature that originates from the U.S. and focus on the mosque as a space where American Muslim identity forms and evolves for both first- and second-generation American Muslims. I examine two American mosques in South Florida as the sites of the development of American Muslim identities based on ethnographic data and participant interviews. I find that the research sites perform functions …

Stress-Strain Management Of Heteroepitaxial Polycrystalline Silicon Carbide Films, Christopher William Locke

USF Tampa Graduate Theses and Dissertations

Silicon carbide (SiC) is one of the hardest known materials and is also, by good fortune, a wide bandgap semiconductor. While the application of SiC for high-temperature and high-power electronics is fairly well known, its utility as a highly robust, chemically-inert material for microelectrical mechanical systems (MEMS) is only beginning to be well recognized. SiC can be grown on both native SiC substrates or on Si using heteroepitaxial growth methods which affords the possibility to use Si micromachining methods to fabricate advanced SiC MEMS devices.

The control of film stress in heteroepitaxial silicon carbide films grown on polysilicon-on-oxide substrates has …

Magneto-Dielectric Polymer Nanocomposite Engineered Substrate For Rf And Microwave Antennas, Cesar A. Morales

USF Tampa Graduate Theses and Dissertations

This dissertation presents the first reported systematic investigation on the implementation of multilayer patch antennas over Fe3O4-based polymer nanocomposite (PNC) magneto-dielectric substrates. The PNC substrate is created by the monodispersion of Fe3O4 nanopthesiss, with mean size of 7.5nm, in a polymeric matrix of Polydimethylsiloxane (PDMS).

Recently, magneto-dielectric substrates have been proposed by several researchers as a means for decreasing the size and increasing the bandwidth of planar antennas. Nevertheless, factors such as high loss and diminished control over magnetic and dielectric properties have hindered the optimal performance of antennas. In addition, the incompatibility and elevated complexity prevents integration of conventional …

Live Video Streaming From Android-Enabled Devices To Web Browsers, Justin M. Bailey

USF Tampa Graduate Theses and Dissertations

The wide-spread adoption of camera-embedded mobile devices along with the ubiquitous connection via WiFi or cellular networks enables people to visually report live events. Current solutions limit the configurability of such services by allowing video streaming only to fixed servers. In addition, the business models of the companies that provide such (free) services insert visual ads in the streamed videos, leading to unnecessary resource consumption.

This thesis proposes an architecture of a real-time video streaming service from an Android mobile device to a server of the user's choice. The real-time video can then be viewed from a web browser. The …

Developmental Trajectories Of Self-Control: Assessing The Stability Hypothesis, James Vance Ray

USF Tampa Graduate Theses and Dissertations

A key proposition of Gottfredson and Hirschi's (1990) self-control theory is the stability hypothesis which suggests that an individual's level of self-control, once established between the ages of 8-10, is stable over the life course. Empirical results from examinations of the stability hypothesis have been mixed. Prior tests of the stability hypothesis have employed aggregate assessment methods (e.g., mean-level and correlational analyses). Such approaches fail to take into account the possibility that individual developmental pathways may differ. This study employs individual longitudinal data over a four year period for 3,249 7^th to 10^th grade subjects to assess the …

Physical Activity Promotion Among School-Aged Children Using Pedometers And Rewards, Kari E. Ek

USF Tampa Graduate Theses and Dissertations

Physical activity is important for children as many children are considered overweight or obese. The benefits of exercise have been demonstrated in empirical studies across all age ranges (Horne, Hardman, Lowe, & Rowlands, 2009; Kelly et al., 2004; Louie & Chan, 2003; Southard & Southard, 2006). In the current study, a multiple baseline design across participants was used to assess the effectiveness of goal setting, reinforcement contingencies, and pedometers that provide feedback to increase step count of 5 participants. During baseline each participant wore a sealed pedometer to assess the average steps the participants took per day. After baseline, each …

Patient Safety In Nursing Homes, Kali Thomas

USF Tampa Graduate Theses and Dissertations

Safety of residents has gained increased popularity in recent years following a report from the Institute of Medicine attributing 98,000 hospital deaths each year to errors by staff. As a result, regulatory agencies, advocates, and health care providers have shifted their focus to understanding patient safety and developing a culture that promotes safety. However, nursing homes lag behind other health care providers in their adoption of a patient safety culture and understanding what factors affect safety in resident care. These insights are needed to ensure that nursing home residents receive the safe care.

The purpose of this dissertation is to …

Fabrication And Characterization Of Electrospun Cactus Mucilage Nanofibers, Yanay Pais

USF Tampa Graduate Theses and Dissertations

This work seeks to fabricate, optimize, and characterize nanofibers of cactus Opuntia ficus-indica mucilage and Poly (vinyl alcohol) (PVA) by electrospinning. Mucilage is a neutral mixture of sugars produced by cactus and PVA is a non-toxic, water-soluble, synthetic polymer, which is widely used as a co-spinning agent for polymers. Mucilage was extracted from the cactus pad and prepared for electrospinning by mixing with acetic acid. Two types of PVA were used differentiating in high and low molecular weights. Concentrations of PVA were varied to find an adequate threshold for fiber formation. Changing the ratio of PVA to cactus mucilage produced …

An Evaluation Of Behavioral Skills Training With The Addition Of A Fluency Component, Ashley Nicole Breeden

USF Tampa Graduate Theses and Dissertations

Behavior Skills Training (BST) typically consists of an initial informational component presented to the learners either vocally, through a handout, presentation, or both. Results from the active student responding literature indicates these methods as the least effective means of conveying important information to learners. This study sought to utilize an alternative instructional component, fluency training, and to evaluate if any effects are observed on implementation of the behavior chain of Discrete Trial Training (DTT). Teacher's had previous training and experience on implementing DTT prior to this study--however, all teachers implemented strategies with low integrity. Teachers were trained to fluent levels …

Identification And Characterization Of The Human Herpesviruses 6a And 6b Genome Integration Into Telomeres Of Human Chromosomes During Latency, Jesse Herbert Arbuckle

USF Tampa Graduate Theses and Dissertations

While the latent genome of most Herpesviruses persists as a nuclear circular episome, previous research has suggested that Human Herpesvirus 6 (HHV-6) may integrate into host cell chromosomes, and be vertically transmitted in the germ-line. Because the HHV-6 genome encodes a perfect TTAGGG telomere repeat array at the right end direct repeat (DR_R) and an imperfect TTAGGG repeat at the end of the left end direct repeat (DR_L), we established a hypothesis that during latency, the HHV-6A and HHV-6B genome integrates into the telomeres of human chromosomes through homologous recombination with the n(TTAGGG) viral repeats, and …

A Case Study Of Adolescent Females' Perceptions Of Identity In An After-School Book Club, Holly Atkins

USF Tampa Graduate Theses and Dissertations

Reading is a perennial educational hot topic - but now extends for beyond early literacy to the secondary level. Reading researchers are growing in our knowledge of how to reach and teach struggling adolescent readers yet too often success in literacy is measured solely by performance on standardized tests. Literacy is seen on one hand as a one-dimensional set of skills students need to possess to be successful in school and their future workplaces. A more expansive view of the importance of literacy and what it means to adolescent females' growth as individuals and members of communities is needed.

Thermal Integrity Profiling Instrumentation Development, Byron Keith Anderson

USF Tampa Graduate Theses and Dissertations

This thesis has shown that the development of the instrumentation necessary to provide in-situ thermal imaging for the determination of homogeneity of concrete is theoretically sound.

Drilled shafts are large diameter underground cast-in-place columns that necessarily rely on sound integrity to properly withstand imposed loadings. As a by-product of the most common construction techniques, the entire process is often completely blind whereby the excavation and concreting processes are conducted beneath the surface of the water table (or slurry level). This results in an inability to inspect the final product and in many cases allows anomalous inclusions (soil cave-ins, slurry pockets, …

Placing Reedy Creek Improvement District In Central Florida: A Case Study In Uneven Geographical Development, Kristine Bezdecny

USF Tampa Graduate Theses and Dissertations

This study is primarily about the theory of uneven geographical development. In an era when it is proclaimed that, through globalization, the world has become flat, the unevenness of economic and social development is often overlooked or suppressed. As the nexus between global and local processes, the urban space often becomes the site of conflict between those defining the hegemonic narrative of the space, from a global and flat perspective; and those experiencing heterogenous local narratives, whose uneven positions are reinforced by this hegemonic narrative.

This study explores the conditions of uneven geographical development in the urban space of central …
