Utilizing Habit Reversal And Contingency Contracting To Impact Eating Habits With Obese Individuals, Christopher Thomas Scull

USF Tampa Graduate Theses and Dissertations

One of the most difficult set of behaviors for individuals to engage in is weight management. The United States boasts an astonishing 35% obesity rate in adults while children show almost a 20% obesity rate. These statistics identify the importance of developing effective methods to help change an individual's eating habits. There are many eating habits that may contribute to an individual gaining or losing weight over a period of time. Simplified habit reversal (SHR) has an impressive history in shaping desirable responses to compete with many different types of habitual behaviors. The present study extended the SHR procedure to …

Direct And Indirect Effects Of Agrochemicals On Bacterial Pathogens And Fecal Indicator Bacteria, Zachery Staley

USF Tampa Graduate Theses and Dissertations

The presence of agrochemical residues in both urban and agricultural water bodies has become ubiquitous, often producing deleterious effects in the impacted watershed including reductions in biodiversity, alterations in species interactions, and toxicity to non-target organisms. While these effects have been studied on metazoan consumers, the consequences of agrochemical contamination on microorganisms, such as bacteria, protozoa, and viruses, are poorly understood. Agrochemicals could act directly on microorganisms, including pathogens, by either facilitating their survival or decreasing their abundance. Further, a multitude of indirect effects of agrochemicals on microorganisms are possible, whereby agrochemicals alter predation, competition, or parasitism on or available …

Efforts To Engage Parents And Case Outcomes In The Child Welfare System, Patty Sharrock

USF Tampa Graduate Theses and Dissertations

The vast majority of child maltreatment in the United States is perpetrated by parents and over half of maltreated children placed in out-of-home care are reunified with the parents from which they were removed. Additional victimization of these children sometimes necessitates their reentry into out-of-home care. These realities emphasize the need to engage parents in assessment, planning, and services throughout the life of a child welfare case. Engagement is a key ingredient in social work practice and is widely accepted in the child protection arena as critical to successful service planning and participation. However, little research has focused on the …

Non-Equilibrium Melting And Sublimation Of Graphene Simulated With Two Interatomic Potentials, Brad Steele

USF Tampa Graduate Theses and Dissertations

The mechanisms of the sublimation of graphene at zero pressure and the condensation of carbon vapor is investigated by molecular dynamics (MD) simulations. The interatomic interactions are described by the Reactive Empirical Bond Order potential (REBO). It is found that graphene sublimates at a temperature of 5,200 K. At the onset of sublimation, defects that contain several pentagons and heptagons are formed, that are shown to evolve from double vacancies and stone wales defects. These defects consisting of pentagons and heptagons act as nucleation sites for the gaseous phase. The influence of the interatomic interactions on the sublimation process are …

Archaeology Of The Early Eighteenth-Century Spanish Fort San José, Northwest Florida, Julie Rogers Saccente

USF Tampa Graduate Theses and Dissertations

The Spanish Fort San José, located on the St. Joseph Peninsula, was occupied from 1719 until 1723. This site is significant as it preserves key details on Spanish settlement, trade, and ethnic diversity on the northern Gulf Coast and relationships with aboriginal and other European peoples of the region. The first archaeological testing of this site was conducted in the 1960s, but limited information exists on this work, and the fort's structural remains are now gone. My research examines a recently discovered artifact collection from this site and combines the new data with information from extant collections from Florida State …

Collecting Stardust: Matter, Memory, And Trauma In Patricio Guzman's Nostalgia For The Light, Nora Szegvari

USF Tampa Graduate Theses and Dissertations

This work situates Patricio Guzmàn's Nostalgia for the Light in the broader field of essay documentary film and unveils it as a locus of discursive resistance and the generative crux of diverse conventionally isolated academic dialogues. In doing so, it addresses the challenging and controversial questions of historical meaning-making, remembrance and oblivion, melancholia and mourning. My thesis also endeavors to detect the dynamic and anxiety-inducing threshold between singularity and collectivity, and the human and the cosmic. I lay the historically unprecedented common ground for trauma theory and the essayistic comportment and argue that bearing the clash of time planes, paradoxicality, …

The primary aim of this study was to investigate source memory performance in individuals diagnosed with Parkinson's disease (PD). The secondary goal was to explore how memory was impacted when subjects were asked to generate responses during encoding. Fifty idiopathic PD patients and fifty healthy control subjects completed a task measuring item memory and source memory which also included a generation manipulation. Relative to controls, PD patients exhibited deficits in source memory but not item memory. Both groups demonstrated enhanced memory performance in the generative condition of the item memory task. The PD group displayed a marginally significant trend toward …

Regulation Of The Tumor Suppresser P53 And Survivin By Ras And Ral Gtpases:Implications For Malignant Transformation, Awet G. Tecleab

USF Tampa Graduate Theses and Dissertations

Abstract

Although the critical role of the small GTPases Ras and Ral in oncogenesis has been well documented, much remains to be investigated about the molecular mechanism by which these GTPases regulate malignant transformation. The work under this thesis made two major contributions to this field. The first is the discovery that K-Ras, RalA and/or RalB are required for the maintenance of the high levels of the anti-apoptotic protein survivin in some human cancer cells, and the second is the demonstration that down regulation of K-Ras, RalA and/or RalB, but not Raf-1 or Akt1/2, stabilizes the tumor suppressor p53 and …

Refiguring Indexicality: Remediation, Film, & Memory In Contemporary Japanese Visual Media, Janine Marie Villot

USF Tampa Graduate Theses and Dissertations

Through an analog between film and memory, I argue contemporary Japanese visual media constantly remediates this relationship in order to develop a more inclusive, plastic indexicality that allows media without direct material contiguity access to an indexicality not typically attributed to it. Amidst the early twenty-first century shift from old, mechanical media to new, electronic media, each Japanese text engages the West through intercultural discourses and intracultural responses, just as Japan has continually encountered the West since its forced opening by Commodore Perry in 1853. The plasticized indexicality figured by contemporary Japanese visual media implies the plastic nature of abstracted …

Investigations For Utilizing Pteropods As Bioindicators Of Environmental Change Along The Western Antarctic Peninsula, Paul Mark Suprenand

USF Tampa Graduate Theses and Dissertations

Pteropods are holoplanktonic gastropod molluscs found globally. Although species diversity is greater at lower latitudes, species abundance is greater at temperate and polar latitudes. Declines in pteropod populations have not only been correlated to declines of their major predators, but pteropods have also been used as bioindicators of global environmental changes such as ocean acidification. With high latitude abundances, pteropods provide significant sustenance for species such as the Atlantic salmon in the Atlantic Ocean and Pleuragramma antarcticum in the Southern Ocean. Because pteropods eat phytoplankton and other pteropods, factors that affect pteropod abundance influence many trophic levels. This dissertation explores …

Examining School Capacity For Inclusion Using A Multi-Dimensional Framework: A Case Study, Amy Lenee-Monnier Toson

USF Tampa Graduate Theses and Dissertations

With the passage of the No Child Left Behind Act (NCLB, 2002) and the reauthorization of the Individuals with Disabilities Education Act (IDEA, 2004), the inclusion of students with disabilities (SWDs) in general education classrooms has become more prevalent within our public schools (DuFour & Eaker, 1998; Mcleskey et al., 2010). Current research on inclusion focuses on student outcomes and procedural changes and not the contexts and capabilities of education leaders who are implementing it. Empirical research that examines how schools have built the capacity for sustaining these models, especially through the perspectives of those who implement it, is limited …

Eco-Epidemiology Of Eastern Equine Encephalitis Virus, Patrick Vander Kelen

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Eastern Equine Encephalitis virus (EEEV) is an alphavirus with high pathogenicity in both humans and horses. Florida continues to have the highest occurrence of human cases in the USA, with four fatalities recorded in 2010. Unlike other states, Florida supports year-round EEEV transmission. This research uses Geographic Information Science (GIS) to examine spatial patterns of documented sentinel seroconversions and horse cases in order to understand the relationships between habitat and transmission intensity of EEEV in Florida. Sentinel sites were categorized as enzootic, periodically enzootic, and negative based on the amount of chicken seroconversions to EEEV. Sentinel sites were analyzed …

An Analysis Of How Female Business Owners Construct And Communicate Identity, Allison Dawn Weidhaas

USF Tampa Graduate Theses and Dissertations

Individuals often get asked: So what do you do? This question can be challenging for those in less traditional work settings, such as stay-at-home-moms and the self-employed. To help women better understand the range of possible responses, this study explores how women in Public Relations respond to identity questions that involve both their work and personal lives. I begin by situating the study within relevant literature on entrepreneurship, female business owners, the history of women in the workplace, work/life issues, Public Relations, the use of language to construct work identity, and structuration theory. I conducted one-on-one qualitative interviews as my …

Boolean Partition Algebras, Joseph Anthony Van Name

USF Tampa Graduate Theses and Dissertations

A Boolean partition algebra is a pair $(B,F)$ where $B$ is a Boolean

algebra and $F$ is a filter on the semilattice of partitions of $B$ where $\bigcup F=B\setminus\{0\}$. In this dissertation, we shall investigate the algebraic theory of Boolean partition algebras and their connection with uniform spaces. In particular, we shall show that the category of complete non-Archimedean uniform spaces

is equivalent to a subcategory of the category of Boolean partition algebras, and notions such as supercompleteness

of non-Archimedean uniform spaces can be formulated in terms of Boolean partition algebras.

The Effect Of Visual Search And Audio-Visual Entrainment On Episodic Memory, Holly Anne Westfall

USF Tampa Graduate Theses and Dissertations

Previous research suggests that larger context effects are observed when participants are required to search a scene in order to find the to-be-remembered stimuli. Similarly, animal research on brain oscillations has shown theta wave activation when animals are searching their environment. These theta wave oscillations are positively correlated with learning. However, theta activation can also occur in response to sensory stimulation, for example, auditory stimulation with binaural beats or visual stimulation with a checkerboard pattern reversal. The results of several studies suggest that while a visual search task seems to reliably improve free recall performance, the effects of passive sensory …

Phenotypic And Genotypic Analysis Of In Vitro Selected Miltefosine Resistant Leishmania Donovani, Brian A. Vesely

USF Tampa Graduate Theses and Dissertations

Abstract

Visceral leishmaniasis is a devastating neglected parasitic disease caused by infection with Leishmania donovani. It life cycle has two stages with promastigote (insect stage) and amastigote (animal stage) morphologies. Miltefosine is currently the only commercially available oral drug available to treat leishmaniasis and recent evidence suggests clinical resistance has emerged. Due to the importance of this drug and the scarcity of new drugs in the pipeline, work has been done on understanding the mechanism(s) of miltefosine, yet the mechanism of action for resistance is still not known.

In previous studies investigators generated miltefosine resistance on the insect vector stage …
