A Tale Of Two Kings: The Use Of King David In The Chronicle Of Pere Iii Of Catalonia, Marrissa Lynne Cook

USF Tampa Graduate Theses and Dissertations

Pere III of Catalonia (1319-1387) began his reign in 1336. As count-king, he reigned over Aragon, Catalonia, and Valencia. The Chronicle of Pere III of Catalonia covers the years 1319-1369, fifty years of a nearly seventy year life. Pere wrote this chronicle in collaboration with his chancery office. Bernat Descoll was the main contributor from the chancery, and he consulted with the king as he wrote it. The chronicle reflects spiritual justifications for actions that occurred during Pere's reign, such as his conflict with the Uniòns of Aragon and Valencia, as well as his conflict with Pedro I of Castile. …

Geochemical Systematics Among Amphibolitic Rocks In The Central Blue Ridge Province Of Southwestern North Carolina, Nathan Collins

USF Tampa Graduate Theses and Dissertations

The Central Blue Ridge sub-province of the southern Appalachian Mountains preserves an unique and complex geologic history. The Cartoogechaye terrane is the westernmost terrane of the Central Blue Ridge sub-province, and is characterized by extensive olistostromal sequences, including mafic-ultramafic massifs, isolated mafic units, and block-in-matrix structures of varying scales. This study investigates the genetic and tectonic relationships, and regional chemical and metamorphic trends of the amphibolitic rocks entrained within units of the Cartoogechaye and nearby terranes, toward constraining the origins of these regional sequences, and examining the rationale for the current Blue Ridge terrane designations.

A distinct compositional variation exists …

Repression/Incitement: Double-Reading Vita Sackville-West's The Edwardians Through Freud And Foucault, Aimee Elizabeth Coley

USF Tampa Graduate Theses and Dissertations

Vita Sackville-West's autobiographical novel The Edwardians lends itself to a double reading: both Freudian and Foucauldian. The Freudian conflict between desire and prohibition plays out in the unresolved Oedipus complex of its protagonist Sebastian, son of the Duchess of Chevron; repression drives Sebastian's behavior in all his relationships. The novel also depicts an upper-class Edwardian society incited to discourse in a Foucauldian sense--a society in which sexual gossip functions as a discourse of power. From a psychoanalytic perspective, this incitement is produced by repression, and functions as a symptom of it. The relationship between repression and incitement suggests the possibility …

Modeling Roadside Safety Hazards To Predict Annual Crash Cost To Encroaching Vehicles In Rural Road Networks, Isidro Delgado

USF Tampa Graduate Theses and Dissertations

Roadside crashes account for a large portion of total fatal crashes that occur annually in the United States. About 30% of those fatalities are the result of single vehicle run-off-road crashes. A large proportion of these fatal crashes occur in rural roads when vehicles depart from the travel lane and collide with trees or other roadside safety hazards. Many of these run-off-road accidents occur in local roads that carry traffic volumes between 1,000 and 20,000 vehicles per day. Many of these roads are part of the jurisdiction of county authorities faced with the dilemma of having too many "potentially dangerous" …

When Does The Straw Break The Camel's Back?: Examination Of The Exclusion-Elicited Anti-Social Behavior Model, Douglas Phillip Cooper

USF Tampa Graduate Theses and Dissertations

Being excluded should motivate pro-social behaviors. Yet, exclusion can incite aggressive and anti-social responses. Two studies were conducted to examine how frequent experiences of exclusion impact self-esteem, perceptions that exclusion is typical of social experiences, and anti-social behaviors. In Study 1, participants completed pre and post-measures of exclusion typicality and self-esteem and reported, over eight weeks, feelings of exclusion and state self-esteem. Results supported the hypotheses in that experiences feeling excluded have direct and indirect effects on state and trait self-esteem as well as on exclusion typicality. In Study 2, participants were exposed to an exclusion manipulation and subsequent aggressive …

Inhibition Of P53 Dna Binding Function By The Mdm2 Acidic Domain, Brittany Lynne Cross

USF Tampa Graduate Theses and Dissertations

MDM2 regulates p53 predominantly by promoting p53 ubiquitination. However, ubiquitination-independent mechanisms of MDM2 have also been implicated. Here we show that MDM2 inhibits p53 DNA binding activity in vitro and in vivo. MDM2 binding promotes p53 to adopt a mutant-like conformation, losing reactivity to antibody Pab1620, while exposing the Pab240 epitope. The acidic domain of MDM2 is required to induce p53 conformational change and inhibit p53 DNA binding. ARF binding to the MDM2 acidic domain restores p53 wild type conformation and rescues DNA binding activity. Furthermore, histone methyl transferase SUV39H1 binding to the MDM2 acidic domain also restores p53 wild …

Analysis Of Ahr Expression And Stability In A Recombinant Yeast Model System, Sarah Elizabeth Cuccinello

USF Tampa Graduate Theses and Dissertations

The aryl hydrocarbon receptor (Ahr) and the aryl hydrocarbon receptor nuclear translocator (Arnt) are well characterized bHLH-PAS transcription factors shown to regulate expression of xenobiotic metabolism genes. Extensive study has shown that upon treatment with certain aromatic hydrocarbons, mammalian cells rapidly activate the Ahr signaling pathway in order to stimulate gene expression and attempt to metabolize the xenobiotic compounds. It has been shown that after DNA-binding, the Ahr but not the Arnt protein, is quickly eliminated from the nuclear compartment thereby attenuating the dose of gene regulation administered by the Ahr*Arnt transcription factor complex. Previous studies have implicated involvement of …

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 …

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 …

"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 …

The Dirt On Prehispanic Water Management At Palmarejo, Honduras, Zaida Darley

USF Tampa Graduate Theses and Dissertations

Water is an essential resource for human life. Even in the tropical environment of the Maya Lowlands, water scarcity is a concern, because the region cycles between abundant rainfall and seasonal droughts. To understand how societies flourished during periods of water scarcity, archaeologists have studied prehispanic water management in the Maya Lowlands. Yet, water management research has tended to focus predominantly on large urban Maya populations, excluding smaller-scale societies that face the same challenges associated with water scarcity. This study investigates the neighboring non-Maya society of Late Classic (A.D.650-900) Palmarejo in northwestern Honduras to explore how water management was organized …

"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 …

Population Genetics Of Amphiuma Means And Siren Lacertina In Central Florida, Anna C. Deyle

USF Tampa Graduate Theses and Dissertations

Population structure can be defined as a difference in the frequencies of alleles among populations, and it is often caused by barriers to dispersal. I used mitochondrial DNA sequences to examine the population structure of two large, aquatic salamanders, Amphiuma means (the Two-Toed Amphiuma) and Siren lacertina (the Greater Siren), at two spatial scales in peninsular Florida. Both species appear to have similar life histories, including poor dry land dispersal capabilities, and I hypothesized that they would exhibit significant population structure at both broad and fine scales. Wetland loss and landscape fragmentation are certain to have caused decreases in abundance …

Restoration Of Displaced Cast-In-Place Concrete Slabs On Grade With The Use Of The Isb-07 Subsurface Support Bracket, Jose Carlos Busquets

USF Tampa Graduate Theses and Dissertations

The restoration of foundations of residential and light commercial structures that have been affected by differential displacement resulting from problematic soil conditions has been an ongoing issue since early times. In Florida, the issue of structures being affected by subsidence of soils related to sinkhole activity has been a problem that has gained more interest and exposure within the last 20 years. Structures affected by sinkholes have been historically addressed by remediating the soil mechanism which caused the structure to displace and then structurally addressing the portions of the structure that have displaced with steel underpins installed on the foundation. …

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. …

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 …

More Than "Modern Day Slavery": Stakeholder Perspectives And Policy On Human Trafficking In Florida, Nathaniel Dickey

USF Tampa Graduate Theses and Dissertations

In recent years, Florida has acquired a reputation as fertile ground for human trafficking. On the heels of state and federal anti-human trafficking legislation, a host of organizations have risen to provide a range of services. In this thesis, I discuss findings from 26 interviews conducted with law enforcement, service providers, legal representatives and trafficked persons to contextualize the variability in the way anti-trafficking work is conceptualized by stakeholders across the state. Additionally, I explore how conflicting organizational policies on the local, state, and federal levels impact stakeholder collaboration and complicate trafficked persons' attempts to navigate already complex processes of …

The Integration Of African Muslim Minority: A Critique Of French Philosophy And Policy, Amber Nichole Dillender

USF Tampa Graduate Theses and Dissertations

The numerous images of violence perpetrated by radicalized followers of Islam, has highlighted the complexities surrounding assimilation and integration of Muslims in Western society. Since the guest worker recruitment from French African colonies initiated after World War II, France has been witness to the unanticipated development of permanent communities of African laborers, many of whom are Muslim. Despite consistent promotion of French monoculture and specifically the use of the assimilation model for integration, segregation of African Muslims has occurred. Through the construction of a single country case study, I explore integration issues surrounding the French Muslim minority communities. I seek …

Steady And Transient Heat Transfer For Jet Impingement On Patterned Surfaces, Mark Michael Dobbertean

USF Tampa Graduate Theses and Dissertations

Free liquid-jet impingement is well researched due to its high heat transfer ability and ease of implementation. This study considers both the steady state and transient heating of a patterned plate under slot-free-liquid jet impingement. The primary working fluid was water (H2O) and the plate material considered was silicon. Calculations were done for Reynolds number (Re) ranging from 500 to 1000 and indentation depths from 0.000125 to 0.0005 m for three different surface configurations. The effect of using different plate materials and R-134a as the working fluid were explored for the rectangular step case. The distributions of the local and …

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 …

Philosophical Precursors To The Radical Enlightenment: Vignettes On The Struggle Between Philosophy And Theology From The Greeks To Leibniz With Special Emphasis On Spinoza, Anthony John Desantis

USF Tampa Graduate Theses and Dissertations

My dissertation lays out some of the chief philosophical precursors to Jonathan Israel's Radical Enlightenment. It investigates the principal question of Will Durant's The Age of Voltaire: "How did it come about that a major part of the educated classes in Europe and America has lost faith in the theology that for fifteen centuries gave supernatural sanctions and supports to the precarious and uncongenial moral code upon which Western civilization has been based?" The aim of this project is both broad and specific: the first is to provide a general history of the philosophical precursors to the Radical Enlightenment up …

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 …

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 …
