Environmental Health In The Latin American And Caribbean Region: Use Of Water Storage Containers, Water Quality, And Community Perception, Erlande Omisca

USF Tampa Graduate Theses and Dissertations

Water quality and availability are important issues in many developing countries where portions of populations still lack access to potable water. Throughout the English-speaking Caribbean and parts of Latin America, households and businesses invest in water supply systems even when they are connected to and pay for water services from a private or state owned provider. Inconsistent supplies of water from the water companies have led many people to invest in storage tanks which, if operated correctly, can provide water throughout the day even when the supply from the main is low or zero. While these individual systems help to …

Catalytic Hydrodehalogenation And Hydrogenation Of Halogenated Aromatic Organic Contaminants For Application To Soil Remediation, Claire J. Osborn

USF Tampa Graduate Theses and Dissertations

The objective of this research was to aid in the development of a new method for removing and destroying soil contaminants. In particular, 1,2,4,5-tetrachlorobenzene (TeCB) was selected for this research. Hydrodehalogenation (HDH) was paired with hydrogenation for remedially destroying TeCB without generating a secondary waste stream in a single batch reactor. Palladium- and rhodium-catalyzed HDH and hydrogenation were applied in a batch reactor at room temperature and moderate hydrogen pressure. Cyclohexane was formed as an end product with benzene as an intermediate reactant.

An analytical method was developed to measure TeCB, benzene, and cyclohexane in a solution of water and …

Evaluating The Effectiveness Of Irrigation Restrictions Within Key Communities In Tampa, Florida, Lin Allen Ozan

USF Tampa Graduate Theses and Dissertations

The City of Tampa, Florida has instituted water restrictions over the past decade that have been primarily aimed at mitigating non-essential usage of water resources by limiting domestic lawn irrigation. The mandatory restrictions are enforced by the issuance of citations to violators, which is intended to promote compliance and deter from subsequent violations. This thesis provides a thorough investigation of historical water restriction with relation to compliance in order to determine which factors might be related to high rates of water usage within key Tampa communities. The objectives are to: (1) develop a GIS data set that can be used …

Analytical Methods To Support Risk Identification And Analysis In Healthcare Systems, Laila Nadime Cure Vellojin

USF Tampa Graduate Theses and Dissertations

Healthcare systems require continuous monitoring of risk to prevent adverse events. Risk analysis is a time consuming activity that depends on the background of analysts and available data. Patient safety data is often incomplete and biased. This research proposes systematic approaches to monitor risk in healthcare using available patient safety data. The methodologies combine traditional healthcare risk analysis methods with safety theory concepts, in an innovative manner, to allocate available evidence to potential risk sources throughout the system. We propose the use of data mining to analyze near-miss reports and guide the identification of risk sources. In addition, we propose …

Using Contextual Cues To Influence The Role Of Priming In The Transformation Of Stimulus Functions: A Relational Frame Theory Investigation In Implicit Social Stereotyping., Jacob Daar

USF Tampa Graduate Theses and Dissertations

This basic study was designed to explore the conceptualization of prejudice as a form of contextually controlled, derived, and arbitrarily applicable relational responding. Basic studies utilizing RFT methodologies have yielded examples of how stimulus functions of one set of stimuli, such as a stereotyped group, can transform the functions of another stimulus, such as an individual. Priming procedures, as contextual cues, have been used to affect prejudicial responding. Stimuli participating in relational frames have been shown to be sensitive to such priming procedures; however, the role of context in the priming of derived relational responses has not yet been established. …

Lead Discovery And Optimization Strategies Towards The Development Of 4(1h)-Quinolones And 1,2,3,4-Tetrahydroacridone Analogs With Antimalarial Activity, Richard Matthew Cross

USF Tampa Graduate Theses and Dissertations

The goal of our research endeavor was to successfully employ modern lead discovery and optimization strategies towards the development and identification of compounds possessing antimalarial activity. Preliminary data from in vitro screening at the Walter Reed Army Institute of Research identified several chemotypes including 4(1H)-quinolones and 1,2,3,4-tetrahydroacridones to have potent antimalarial activities. Multiple synthetic routes were devised and implemented which enabled the rapid preparation and isolation of over 400 structurally diverse 4(1H)-quinolones and 1,2,3,4-tetrahydroacridones.

Our research towards discovering and optimizing antimalarials was inspired from the severe impact malaria has had on our planet especially on impoverished countries. There are over …

Mechanistic Modeling Of Photocatalytic Water Disinfection, Omatoyo Kofi Dalrymple

USF Tampa Graduate Theses and Dissertations

The main goal of this research was to develop a mechanism-based model for photocatalytic disinfection of bacteria in water using suspended catalyst pthesiss in batch reactors. The photocatalytic disinfection process occurs as a semiconductor photocatalyst, most commonly titanium dioxide (TiO₂), is irradiated with light of wavelength less than 380 nm to produce hydroxyl radicals and other highly reactive oxidants which can inactivate microorganisms. Photocatalytic disinfection involves a complex interaction of many fundamental mechanisms such as light absorption and scattering by semiconductor pthesiss, electrochemical surface reactions, and heterogeneous colloidal stability. Current models, based largely on chemical reacting systems, do …

Microbial Landscapes Of Corals And Ctenophores, Camille Arian Daniels

USF Tampa Graduate Theses and Dissertations

As technology and engineering allow mankind to survey nature at finer scales, the importance of bacteria has been elucidated in their metabolic diversity, ability to transfer genetic information, involvement in biogeochemical cycling, and sheer abundance. With an individual domain of life unto themselves, this diverse group of microorganisms plays an integral role in facilitating life on land and in the oceans, and is second only to viruses in abundance on Earth. They carve niches in a wide range of environments, including those inhospitable to other life forms, and reside in concert or to the detriment of other microbes and/or hosts …

"A Blaze Of Light And Finery": The Victorian Theater And The Victorian Theatrical Novel, Dorinda Mari Davis

USF Tampa Graduate Theses and Dissertations

The concept of the Victorian antitheatrical prejudice is both well-established and well-respected. This paper, however, examining the Victorian theatrical novel and the Victorian theater in terms of that prejudice, finds the ready assumption of the prejudice to be problematic at best. A close look at three novels that together span the early to mid-nineteenth century shows that, far from being ubiquitous and unilateral, antitheatricality was in many cases an anomaly; indeed, many of those novelistic elements that have long been assumed to be antitheatrical address different issues altogether. Employing close readings of the novels--Jane Austen's Mansfield Park, Charles Dickens's …

"Can't Buy Me Wealth": Racial Segregation And Housing Wealth In Hillsborough County, Florida, Natalie Marie Delia Deckard

USF Tampa Graduate Theses and Dissertations

Informed by the literature regarding the gap in wealth between white and non-white households in the United States, as well as the literature on segregation and neighborhood preference, this research explores the home value component of the wealth gap in Hillsborough County, Florida. It finds that homes in Predominantly Black or Hispanic neighborhoods are not only undervalued compared to Predominantly White and heterogeneous neighborhoods, but have appreciated more slowly at least since 2000. The research also finds that buyers identifying as black or Hispanic are more likely than those identifying as white or "other" to purchase homes in Predominantly Black …

Theoretical And Experimental Analysis Of Power And Cooling Cogeneration Utilizing Low Temperature Heat Sources, Gökmen Demirkaya

USF Tampa Graduate Theses and Dissertations

Development of innovative thermodynamic cycles is important for the efficient utilization of low-temperature heat sources such as solar, geothermal, and waste heat sources. Binary mixtures exhibit variable boiling temperatures during the boiling process, which leads to a good thermal match between the heating fluid and working fluid for efficient heat source utilization. This study presents a theoretical and an experimental analysis of a combined power/cooling cycle, which combines the Rankine and absorption refrigeration cycles, uses ammonia-water mixture as the working fluid and produces power and refrigeration, while power is the primary goal. This cycle, also known as the Goswami Cycle, …

Anaerobic Membrane Bioreactor (Anmbr) For Treatment Of Landfill Leachate And Removal Of Micropollutants, Anh Tien Do

USF Tampa Graduate Theses and Dissertations

To date, most studies on the fate and removal of endocrine disrupting compounds (EDCs) and pharmaceutical and personal care products (PPCPs) in wastewater focus on their fate in municipal wastewater treatment plants, and mostly under aerobic condition. There are limited studies related to anaerobic condition and (to our knowledge) no study on the removal of EDCs in landfill leachate by AnMBR. Moreover, for most studies under anaerobic condition, the removal of EDCs was only reported in the liquid phase; solid phase extraction was not reported, thereby preventing mass balance in the studies.

This research was conducted to investigate the potential …

USF Tampa Graduate Theses and Dissertations

This study investigates adolescents' relationships with food and other community and household members' perceptions of youth and their food consumption to understand the multifactorial dynamic processes which create nutritional outcomes among urban and rural youth in central Tanzania. Youth are an important and demographically large population in developing countries. The identities created during this distinct stage of cultural production can be reflected in youths' food consumption and relationships with food. Nutrition likely affects how youth transition through a variety of states, including their growth and development stages, primary to secondary to higher education, child to parent, or unemployed to employed. …

A National Survey Of Instructional Strategies Used To Teach Information Systems Courses: An Exploratory Investigation, Yenni Merlin Djajalaksana

USF Tampa Graduate Theses and Dissertations

Many universities and colleges have placed increased emphasis on teaching excellence in higher education. Efforts to promote teaching excellence vary from the development of alternative new pedagogies as well as research exploring strategies to improve existing teaching practices. Logically, different disciplines employ different instructional strategies to prepare their graduates with specific skills, knowledge, and attitudes. This study examined the instructional strategies used most frequently in the information systems discipline and was inspired by Shulman's (2005) concept of signature pedagogies - the unique but pervasive ways of teaching within a discipline or profession.

This dissertation reports a national survey of instructional …

Development Of A Non-Invasive Electrode For Intradermal Electrically Mediated Dna Vaccination, Amy Lynn Donate

USF Tampa Graduate Theses and Dissertations

Current progress in the development of vaccines has decreased the incidence of fatal and non-fatal infections and increased longevity. However, new technologies need to be developed to combat an emerging generation of infectious diseases. DNA vaccination has been demonstrated to have great potential for use against a wide variety of diseases. Alone, this vaccine technology does not generate a significant immune response for vaccination, but combined with delivery by electroporation (EP), can enhance plasmid expression and immunity against the expressed antigen. Most EP systems, while effective, can be invasive and painful making them less desirable for use in vaccination. Our …

Apparent Total Evaporative Resistance Values From Human Trials Over A Range Of Metabolic And Heat Stress Levels, Matthew David Dooris

USF Tampa Graduate Theses and Dissertations

Failure to maintain thermal equilibrium can cause uncontrollable increases in body core temperature beyond critical upper limits. In selecting clothing, consideration must be given to the heat transfer properties of clothing that may restrict the cooling capacity of the human body under heat stress conditions, most importantly, apparent total evaporative resistance (R_e,T,_a). This study calculated and compared R_e,T,_a for five clothing ensembles under varying heat stress conditions, including three relative humidity (RH) levels and three stages of heat stress to determine if R_e,T,_a values varied or remained the same with …

The Tyranny Of Plot: Anzia Yezierska's Struggle To Free The Voices Of Her Community Through The Autobiographical Self, Kristie Kelly Dowling

USF Tampa Graduate Theses and Dissertations

This thesis explores the very different ways that both the novel and autobiography mediate individual and group identities by comparing Anzia Yezierska's novel Salome of the Tenements to her autobiography Red Ribbon on a White Horse. Yezierska's texts establish the inherent difference between the novel and autobiography in that her novels contribute to the dominant ideology by colluding with the capitalist narrative of individualism while her autobiography resists that very narrative. In calling forth the multiple voices of her community, her autobiography reveals, in a series of metatextual comments, the fictional nature of the self and autobiography. Comparing these …

The Archaeology Of Yon Mound And Village, Middle Apalachicola River Valley, Northwest Florida, Jeffrey Patrick Du Vernay

USF Tampa Graduate Theses and Dissertations

A growing trend in Mississippian research in the archaeology of the southeastern United States stresses the need to shift away from categorizing generalizations (e.g., the concept of chiefdoms) that have been used to characterize Mississippi-period (A.D. 1000-1600) societies and advocates elucidating the unique occupational histories of Mississippian communities. This dissertation follows this trend with the goal of identifying and interpreting the particular historical and developmental trajectory of the Yon mound and village site (8Li2), a Fort Walton Mississippian site situated in the middle Apalachicola River valley, northwest Florida. Since its initial recording by Clarence Bloomfield Moore at the turn of …

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.
