The Effects Of Racial Bias On Perceptions Of Intimate Partner Violence Scenarios, Batya Yisraela Rubenstein

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to explore how racial bias affects perceptions of intimate partner violence (IPV). Public perceptions of IPV have been studied under numerous contexts to ascertain how characteristics of victim and the offender can affect these attitudes. A portion of this body of research has been dedicated to understanding the role of race in perceptions of IPV and a large portion of the findings have been mixed due to the interaction of biases and attitudes about race and IPV. Very few studies have looked at multiple forms of IPV in comparison with one another while also …

Inhibiting The Interaction Between Grp94 And Myocilin To Treat Primary Open-Angle Glaucoma, Andrew Stothert

USF Tampa Graduate Theses and Dissertations

Glaucoma is a neurodegenerative protein misfolding disorder classified by increases in IOP, damage to retinal ganglion cells (RGCs), optic nerve (ON) head damage, and progressive irreversible blindness. Primary open-angle glaucoma (POAG) is the most common form of glaucoma, constituting over 90% of clinical cases. POAG is observed in patients where normal outflow channels, mainly the trabecular meshwork (TM), are exposed at the angle formed by the iris and cornea. However, due to TM cellular dysfunction, aqueous outflow resistance is increased preventing normal circulation of aqueous humor. Recent studies have shown that in 2-4% of POAG cases, increased intracellular levels of …

Cardiovascular Disease Risk Scores And Novel Risk Factors In Relation To Race And Gender, Johanna Wilson

USF Tampa Graduate Theses and Dissertations

The use of cardiovascular risk scores remains the foundation for risk stratification to guide clinical management. Clinicians have access to several cardiovascular risk scores in practice settings. While having several risk scores with different risk factors may provide more information, it does not imply accuracy of the cardiovascular risk score used to calculate individual patient cardiovascular risk. The objective of this study was to compare the Framingham Risk score, Reynolds Risk scores, and the Pooled Cohort Risk Equation (3 commonly used equations) scores with respect to ability to predict cardiovascular events in a diverse ethnic population. Additionally, the potential predictive …

Changes And Challenges In Diplomacy: An Evaluation Of The Ministry Of Foreign Affairs In The Dominican Republic, Yudelka Santana

USF Tampa Graduate Theses and Dissertations

This research analyzes why diplomacy is failing in the Dominican Republic. In this thesis, I describe how Dominicans construct their foreign affairs, and the limitations that diplomacy has had in the country. In order to achieve these goals, I have analyzed official documents such as the 2013 and 2015 payrolls of the Ministry of Foreign Affairs, and legal documents including Article 146 from the Constitution, Organic Law 314 from 1964, and the Protocol of Transparency and Institutions. I argue that the Ministry of Foreign Affairs in the Dominican Republic lacks seriousness and is characterized by the following variables: (1) patronage, …

Cmg Helicase Assembly And Activation: Regulation By C-Myc Through Chromatin Decondensation And Novel Therapeutic Avenues For Cancer Treatment, Victoria Bryant

USF Tampa Graduate Theses and Dissertations

The CMG (Cdc45, MCM, GINS) helicase is required for cellular proliferation and functions to unwind double-stranded DNA to allow the replication machinery to duplicate the genome. Cancer cells mismanage helicase activation through a variety of mechanisms, leading to the potential for the development of novel anti-cancer treatments. Mammalian cells load an excess of MCM complexes that act as reserves for new replication origins to be created when replication forks stall due to stress conditions, such as drug treatment. Targeting the helicase through inhibition of the MCM complex has sensitized cancer cells to drugs that inhibit DNA replication, such as aphidicolin …

How Presidents Can Become "Hip" By Using High Definition Metaphors Strategic Communication Of Leadership In A Digital Age, Mirela Camelia Stimus

USF Tampa Graduate Theses and Dissertations

The aim of this interdisciplinary research was to see whether American presidents can reach Millennials more effectively in the digital age while publicly advancing the legislative agenda of their administration. The rationale is that presidents need to gain public support to pressure Congress into passing their legislation; while doing that, they can capture the public’s interest in politics and educate civically the most inattentive audience. To accomplish the task, strategic messaging adequate to digital media is necessary. Millennials appear as having modest interest and knowledge of politics despite their intense presence on digital media. On the other hand, they represent …

The Role Of Threat-Based Beliefs In Mental Health Help-Seeking Processes For Depression, Jason I. Chen

USF Tampa Graduate Theses and Dissertations

Mental illness among college students is a significant public health concern. Among mental health issues, one of the most prevalent and impairing is depression. Although many students experience depression, the majority do not seek help. Past research has shown that stigma beliefs are associated with help-seeking, but interventions targeting stigma have been unsuccessful at increasing help-seeking prompting the need to explore alternative models. Currently, there has been little research evaluating the role of threat-based beliefs related to help-seeking processes. As well, it remains unclear how different threat-based beliefs may interact and be related to help-seeking intentions.

The purpose of these …

USF Tampa Graduate Theses and Dissertations

This research examined demographic factors and reported preferential learning mode among a sample of Florida Osher Lifelong Learning Institute (OLLI) members compared to a national sample profile of OLLI members. This study was prompted by an earlier study of OLLI members conducted by the National Resource Center (NRC) for OLLIs, which produced a national profile describing OLLI members. Although there was a national profile for OLLI members, there were no existing profiles of Florida OLLI members that could be used by OLLI administrators and instructors.

This study employed an online survey to compare data between the national OLLI member profile …

Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin

USF Tampa Graduate Theses and Dissertations

Tauopathies are neurodegenerative diseases that affect millions of people around the world. Tauopathies include more than 20 neurodegenerative diseases. Some of the most common tauopathies are Alzheimer’s disease (AD), frontotemporal dementia (FTD), chronic traumatic encephalopathy (CTE), Pick’s disease, corticobasal degeneration, progressive supranuclear palsy (PSP), agyrophillic grain disease, and amyotrophic lateral sclerosis (ALS). These diseases can cause significant memory loss, behavioral changes, motor deficits and speech impairments. Tauopathies stem from accumulation of the microtubule associated protein tau (MAPT). Tau stabilizes microtubules and helps with axonal transport. In a disease state tau becomes hyperphosphorylated and truncated leading to its aggregation. More recently …

Peer Victimization In Youth With High-Functioning Autism Spectrum Disorder, Danielle Ung

USF Tampa Graduate Theses and Dissertations

Peer victimization is a serious national concern affecting as many as 54% of typically developing children and adolescents. Although an extensive body of literature on peer victimization in typically developing youth exists, few studies have focused on how this problem affects youth with autism spectrum disorders (ASD) who may be at a higher risk to experience peer victimization due to ASD symptomology and other common comorbid characteristics (e.g., anxiety and depressive symptoms) that may invite peer aggression. In this study, 81 school-aged youth between the ages of 9 and 17 years (M= 11.91, SD= 2.32) who were …

Neighborhood Perceptions Of Proximal Industries In Progress Village, Fl, Laura E. Baum

USF Tampa Graduate Theses and Dissertations

Progress Village, a historically Black neighborhood outside of Tampa, FL, encountered structural violence that included construction of an adjacent phosphogypsum stack. Why the neighborhood signed a legal agreement with the stack’s operating industry and the impacts of this decision provides a lesson in critical environmental justice. Theories of urban political ecology frame exploration of resident priorities, relationships with industry, risk perceptions, and health concerns. Utilizing activist anthropology, this thesis aims to be mutually beneficial to scholarly and neighborhood development. Ultimately, this research demonstrates how southern gradualism, racism, and a trend towards isolationism created today’s striving, yet marginalized and divided community. …

Beauty, Sex, And Death: The Role Of Mortality Salience In Objectification Processes, Kasey Lynn Morris

USF Tampa Graduate Theses and Dissertations

Although much attention has been paid to the consequences of objectification, relatively little research has focused on the question of why women are objectified. From a terror management theory perspective, the association of women with (literal) objects strips them of the qualities that are threatening (on account of mortality concerns). Sexualization, however, underscores women’s animal nature, and this association is problematic in the management of existential anxiety. The current research builds on a distinction between sexual and appearance-focused objectification to identify the existential mechanisms in the motivation to dehumanize, and subsequently harm, women. Consistent with the hypothesis, participants primed with …

An Integrative Model Of Situation Awareness, Andrew Thurston

USF Tampa Graduate Theses and Dissertations

In aviation safety incident reports, lack of situation awareness (SA) is often attributed as the cause of negative safety outcomes, such as accidents. While the predominant model of SA has identified three components of SA, perception, comprehension, and projection, assumptions of their relationships with each other and external criteria are yet tested empirically. Specifically, SA theory suggests comprehension SA fully mediates the relationship between perception and projection SA. Additionally, research on the relationships between individual differences and SA is lacking. The purpose of the current study is to test a comprehensive model of SA which simultaneously examines the described mediation, …

Gamma Aapeptides As Host Defense Peptide Mimics, Yaqiong Li

USF Tampa Graduate Theses and Dissertations

There has been increasing concern regarding the emergence of multi-drug resistant pathogens. The resistance develops when pathogens, especially bacteria, are frequently exposed to conventional antibiotics, as they are heavily used in both human and livestock. This is due to the high target specificity of conventional antibiotics, which places pathogens in high selective pressures and eventually results in drug resistant by mutations. To address this issue, global actions and cooperation are needed. At the same time, new technologies and strategies need to be developed. Host defense peptides (HDPs) are widely found in the innate immune system. They show both direct antimicrobial …

When Maps Ignore The Territory: An Examination Of Gendered Language In Cancer Patient Literature, Joanna Bartell

USF Tampa Graduate Theses and Dissertations

Cancer patients report having a high need for cancer information. Several studies show that the majority of patients surveyed report preferring information from the American Cancer Society (ACS). Ranging up to 129 pages, the ACS’ Detailed Guides (DG) are widely distributed throughout the United States, and offer patients an authoritative guide to help patients navigate the difficult terrain of the cancer journey. This dissertation examines the ACS’ cervical, endometrial, ovarian, penile, prostate, testicular, and vaginal cancer guides. Through a rhetorical analysis of the 7 guides, it was shown that the ACS DGs in question foster gendered narratives that strictly limit …

The Role Of Social Ties In Dynamic Networks, Xiang Zuo

USF Tampa Graduate Theses and Dissertations

Social networks are everywhere, from face-to-face activities to online social networks such as Flickr, YouTube and Facebook. In social networks, ties (relationships) are connections between people. The change of social relationships over time consequently leads to the evolution of the social network structure. At the same time, ties serve as carriers to transfer pieces of information from one person to another.

Studying social ties is critical to understanding the fundamental processes behind the network. Although many studies on social networks have been carried out over the last many decades, most of the work either used small in-lab datasets, or focused …
