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 …

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 …

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 …

Knowledge And Practice Of Reproductive Health Among Mothers And Their Impact On Fetal Birth Outcomes: A Case Of Eritrea, Winta Negusse Araya

USF Tampa Graduate Theses and Dissertations

Maternal mortality is a huge concern globally leading to more than a quarter of a million deaths every year. Similarly, an estimated 4 million neonates die every year worldwide, contributing to the majority of deaths of under-5 children. The majority of these deaths take place in under-developed countries, and specifically, in the sub-Saharan Africa region. It is evidenced that maternal ill-health and death contribute to the majority of child deaths. Reducing the death of children under 5 years by two thirds and also improving maternal health/reducing maternal death by three quarters between the years 1990 and 2015 are two of …

Environmental Implications Of Pavements: A Life Cycle View, Bin Yu

USF Tampa Graduate Theses and Dissertations

Environmental aspect of pavement, unlike its economic counterpart, is seldom considered in the theoretical study and field practices. As a highly energy and material intensive infrastructure, pavement has great potential to contribute to the environment protection, which, in root, depends on the in-depth understanding of the environmental impacts, holistically and specifically. A life cycle assessment (LCA) model is used to fulfill the goal.

This research firstly carried out extensive literature review of LCA studies on pavement to identify the major research gaps, including: incompleteness of the methodology, controversy of the functional unit, and unawareness of feedstock energy of asphalt, etc. …

Motivational Interviewing To Promote Physical Activity In Breast Cancer Survivors, Yasmin Asvat Patel

USF Tampa Graduate Theses and Dissertations

Abstract

Despite documented health benefits, most breast cancer survivors (BCS) do not meet physical activity (PA) guidelines. Hence, evaluating diverse intervention approaches to promote PA in BCS is imperative. Motivational Interviewing (MI) offers a non-prescriptive, client-centered approach to PA promotion that has not been adequately evaluated in BCS. In this randomized-controlled trial, 66 Stage 0-IIIa BCS within three years post-treatment, insufficiently active and contemplating increasing PA were randomly assigned to a MI intervention or an active control condition. The MI intervention implemented motivational and behavior change strategies consistent with MI principles. The active control condition provided education and prescriptive recommendations …

USF Tampa Graduate Theses and Dissertations

In spite of decades-long development programs, Lesotho faces an ongoing problem of water insecurity with far- reaching individual and social impacts. The purpose of this research was to understand how women in Lesotho are impacted by the synergistic epidemics, or syndemics, of water insecurity and HIV/AIDS and how they respond to these forces. Little has been done to address how water insecurity, defined in terms of both sufficient amount and quality of water, catalyzes the syndemic impact on the people of Lesotho. Access to safe and reliable sources of water is crucial for all individuals, particularly those who have been …

An Investigation Of Ocb Demands And Workplace Behaviors, Jeremy Allen Bauer

USF Tampa Graduate Theses and Dissertations

Abstract

The current study investigated the relationship between demands for organizational citizenship behaviors and future displays of organizational citizenship and counterproductive work behaviors. Such demands are conceptualized as workplace conditions that make it difficult for employees to complete their job (i.e., organizational constraints), performance failures of coworkers such as incomplete or incorrectly done tasks (i.e., coworker failure) and direct or indirect request from the supervisors to commit more organizational citizenship behaviors (i.e., supervisor pressure). Additionally, the effect of negative affectivity, hostile attribution bias, attributions of blame, and target specific scales of workplace behaviors were investigated. The design of the current …

Exploring Potential Risk Factors Of Fetal Origins Of Diabetes: Maternal Stressors During Pregnancy And Birth Outcomes Among Women In A Hospital In The Municipality Of Caguas, Puerto Rico, Juan Pablo Arroyo

USF Tampa Graduate Theses and Dissertations

Puerto Rico has the highest prevalence of type 2 diabetes, low birth-weight, and the second highest prevalence of preterm-birth in all the U.S. and its non-incorporated territories. These conditions are related. Birth-weight at both ends of the spectrum and preterm-birth are associated with an increased risk for developing type 2 diabetes and immune-inflammatory dysregulations. Maternal psychosocial stressors during pregnancy have also been recognized as potential risk factors for type 2 diabetes, and have been consistently associated with preterm-birth and low birth-weight across populations. Current evidence points toward epigenetic fetal metabolic-programming as the mechanism that underlies the increased risk for the …

Curriculum Gatekeeping In Global Education: Global Educators' Perspectives, Robert Wayne Bailey

USF Tampa Graduate Theses and Dissertations

Teaching social studies from a global perspective has been resisted by many since its inception (Kirkwood, 2009). Critics have labeled the theory anti-American and unpatriotic (Schlafly, 1986; Burack, 2001). Others are concerned with its shifting perspectives and apparent lack of core facts (Finn, 1988). Over time, some critics have changed their stance on global teaching and now endorse the idea (Ravitch, 2010). This qualitative case study sought to identify the barriers seven self-proclaimed global educators faced while teaching global themes and to identify the effective gatekeeping strategies for circumventing such obstacles. The goal was to provide a rich, compelling account …

The Effect Of Drug Resistance On Plasmodium Falciparum Transmission And Gametocyte Development, Samantha Olivia Aylor

USF Tampa Graduate Theses and Dissertations

In order to reduce malaria prevalence worldwide, a better understanding of parasite transmission and the effect of drug resistance is needed. The effect of drug resistance on malaria transmission has been examined for some drugs, but not for mitochondrial inhibitors such as atovaquone and the current basis of malaria therapy, artemisinin. Therefore, the goal of this study was to produce gametocytes, the life cycle stage that transmits from mosquito to human, in several different drug resistant patient isolates as well as to determine the effect of drug resistance on gametocyte development and transmission. Previous studies have shown that the mutation …

Exploring Local Food System Practices And Perceptions: Insights From Florida's Snap-Authorized Farmers' Markets, Leslie Babiak

USF Tampa Graduate Theses and Dissertations

Despite heightened interest in creating local food systems that enhance health of ecologies, economies, and all members of communities, the public space of farmers' markets is far less than inherently equitable. This is particularly concerning given America's unprecedented crisis of food hardship and related disease, which disproportionately affects lower income populations. This research addresses the social justice implications of SNAP (food stamp) operations for locally oriented food systems. Pioneering practices of three of Florida's SNAP-authorized farmers' markets, and the attitudes and behaviors of one-hundred-seventy-six market patrons, were explored through customer surveys, market manager interviews, and environmental assessments. Qualitative and quantitative …

Rhetorical Spirits: Spirituality As Rhetorical Device In New Age Womanist Of Color Texts, Ronisha Witlee Browdy

USF Tampa Graduate Theses and Dissertations

Throughout history African–American women have struggled against oppressions that have stereotyped their identities, scrutinized their character, and ultimately labeled their bodies inferior and inhuman. Despite the debilitating ideologies and barriers African–American women have been forced to operate within, they have fought against these racist, sexist, classist, homophobic environments, crafting their own “new” ethos through writing, as well as entertainment and popular culture. Although Black women remain plagued by history, the New Age of the 1980s as discussed by Akasha Gloria Hull in Soul Talk: The New Spirituality of African–American Women seemed to spark a new spirituality amongst African–American women.

Middle And High School Predictors Of Off-Track Status In Early Warning Systems, Amber Brundage

USF Tampa Graduate Theses and Dissertations

It is important to identify students at-risk for school non-completion as early as possible. Research has demonstrated that data sources such as teacher nomination and individual demographic characteristics are less accurate identification methods of students who are at-risk for not graduating on-time. Instead, the use of early warning systems (EWS) based upon research validated indicators that reliably identify students who are Off-track, or at-risk for not graduating on-time, has been a promising approach. Questions remain though about the relationship of Off-track Status at an earlier time point to Off-track Status at a later time point as well as the relationship …

Net Effects Of Batrachochytrium Dendrobatidis (Bd) And Fungicides On Anurans Across Life Stages, Jenise Brown

USF Tampa Graduate Theses and Dissertations

Amphibians are declining at alarming rates globally. Multiple factors contribute to these declines, including chemical contaminants and emergent diseases. In recent years, agrochemical use, especially fungicide applications, has increased considerably. Previous studies have demonstrated that these agrochemicals leave application sites and enter wetlands via runoff and have detrimental effects on non-target organisms. For example, exposure to contaminants can have multifarious effects on amphibians, such as reducing their ability to deal with a secondary stressor, such as disease.

A pathogen that is found concomitant with chemical contaminants in aquatic systems is Batrachochytrium dendrobatidis (Bd). Bd has decimated amphibian populations worldwide. Susceptibility …
