L-Ergothioneine Treatment In Old Cba/Caj Male Mice Slows The Progression Of Age-Related Hearing Loss, Mark A. Bauer

USF Tampa Graduate Theses and Dissertations

The naturally occurring amino acid, L-Ergothioneine (EGT), has immense potential as a therapeutic, having shown promise in the treatment of other disease models, including neurological disorders. EGT is naturally uptaken into cells via its specific receptor, OCTN1, suggesting that it is highly conserved, to be utilized by cells as an antioxidant and anti-inflammatory, particularly under stressed conditions. In our current study, EGT was administered over a period of 6 months to 25-26 month old CBA/CaJ mice as a possible treatment for age-related hearing loss (ARHL), since presbycusis has been linked to higher levels of cochlear oxidative stress, apoptosis and chronic …

Towards Precision Audiology: Perceptual Profiles & Their Relation To Ecologically Valid Communication Assessments, Dana Cherri

USF Tampa Graduate Theses and Dissertations

Living in a sonic world, a person with hearing loss experiences difficulty in communicating with others. One of the reasons why some people with hearing loss do not wear hearing aids (HAs) is limited perceived benefit, which may result from HAs that are not fit using “best practices” or because the best practices fail to address individual difficulties experienced by the listener. The typical audiogram provides information regarding audibility as a function of frequency and is used to establish degree, type, and configuration of hearing loss, but does not measure the ability of an individual to process various components of …

Designing A Messaging Strategy To Improve Information Security Policy Compliance, Federico Giovannetti

USF Tampa Graduate Theses and Dissertations

Lack of employee compliance with information security policies is a key factor driving security incidents. Information security practitioners struggle to enforce policy compliance while employees try to curtail safeguards in favor of expediency and other perceived business goals. Several studies have shown individual and organizational factors influencing this type of employee behavior. However, few have recommended management-level interventions that can be used as a solution framework by information security practitioners.

This research utilized the Design Science Research (DSR) methodology to develop a management-level intervention based on a messaging strategy that aims to help information security practitioners improve the information security …

Development Of An Automated Platform For Sensing And Differentiating Vapor-Phase Btex Constituents, Jonathan Samuelson

USF Tampa Graduate Theses and Dissertations

Light aromatic hydrocarbons are an inevitable byproduct of fossil fuel extraction, refinement, distribution, and use.

Minecraft In Language Teacher Education: Acceptance And Integration In Practice, Kristen E. Fung

USF Tampa Graduate Theses and Dissertations

In today’s technological era, understanding if and how teachers’ acceptance and integration of technology evolves is critical to understanding their needs. Technology creates complicated demands on educators and research shows various factors may contribute to their limited success at integrating it (Bustos & Nussbaum, 2009). Research also shows that teachers’ perceptions and attitudes towards pedagogical innovations and information and communication technologies are prominent factors that impact adoption and integration (Tejedor & Muñoz-Repiso, 2006), and the perceptions teachers develop as pre-service teachers influence their classroom performance as in-service teachers (Moon et al., 2016). While research shows plentiful evidence of the educational …

Generative Spatio-Temporal And Multimodal Analysis Of Neonatal Pain, Md Sirajus Salekin

USF Tampa Graduate Theses and Dissertations

Neonates can not express their pain like an adult person. Due to the lacking of proper muscle growth and inability to express non-verbally, it is difficult to understand their emotional status. In addition, if the neonates are under any treatment or left monitored after any major surgeries (post-operative), it is more difficult to understand their pain due to the side effect of medications and the caring system (i.e. intubated, masked face, covered body with blanket, etc.). In a clinical environment, usually, bedside nurses routinely observe the neonate and measure the pain status following any standard clinical pain scale. But current …

Beyond Health And Animal Rights: A Study In Black Veganism, Wendy J. Rib

USF Tampa Graduate Theses and Dissertations

Veganism, or the avoidance of animal products, has been recognized by nutritionists and food scientists as a lifestyle choice associated with good health and lower prevalence of diabetes, obesity, hypertension, and heart disease. However, the choice to eschew all animal products is frequently more than just a diet. Many people practice veganism as part of a larger reformative social movement, seeking permanent change in food structures, advancing policies in animal welfare and transforming their everyday lives in the quest for cultural acceptance. Although the number of people who identify as vegans appears to be growing, it is often assumed that …

Longitudinal Associations Among Life Values, Alcohol Use, And Alcohol Abuse Symptoms From Adolescence To Adulthood, Connor Habecker

USF Tampa Graduate Theses and Dissertations

Investigating life value trends, the pro-social and anti-social characteristics that play a role in decision making, is an understudied field in adolescents. In addressing adolescent alcohol consumption as a public health concern, life values may provide needed background in understanding and influencing adolescent behavior toward pro-social values and away from known risk factors, such as alcohol consumption. By modeling life value trends of adolescents and the associations between each life value and the outcomes of alcohol use and alcohol abuse, there may be primordial level intervention opportunities as opposed to the current, largely ineffective, tertiary level interventions. This thesis utilizes …

Preventing Variadic Function Attacks Through Argument Width Counting, Brennan Ward

USF Tampa Graduate Theses and Dissertations

Format String attacks, first noted in June 2000 [1], are a type of attack in which anadversary has control of the string argument (the format string) passed to a string format function (such as printf). Such control allows the attacker to read and write arbitrary program memory. To prevent these attacks, various methodologies have been proposed, each with their own costs and benefits. I present a novel solution to this problem through argument width counting, ensuring that such format functions cannot access stack memory beyond the space where arguments were placed. Additionally, I show how this approach can be expanded …

African American Males' Perception Of Factors That Contribute To Success In Higher Education, Gary D. Oliver

USF Tampa Graduate Theses and Dissertations

Over the past decades, many studies have concluded that African American students' college completion rate and success lag far behind other students attending college in the United States (The JBHE Foundation, Inc., 2006). More specifically, these studies have confirmed that African American male students' success rates remain disproportionally low compared to other ethnic male groups. Unfortunately, few notable studies identifying African American males achieving higher education or completing their academic pursuits have been presented as part of the Black male student narrative.

This study aimed to understand better the resources and experiences that positively affect African American males who completed …
