Speaking Up: A Courage Framework Of Bipoc Voices In The Workplace, Aishah Khan

All Theses

Despite the many beneficial outcomes of voice in the workplace, employers and employees do not often utilize it to its full potential, particularly those from historically marginalized groups. Past literature has examined the many ways in which the experience of minority-group members differs from that of majority-group members; however, scarce work has been done exploring the “mental calculus” that those from marginalized groups go through when deciding whether to advocate for themselves or others at work. To provide insight into this specific experience, I manipulated representation and context in a novel fashion – and examined if and how safety, risk, …

Athlete Soreness Self-Reporting For Increased Sports Recovery, Marissa Bennett

All Theses

With 70-80% of athletes choosing to withhold soreness/injury-related information from sports staff (Jessiman-Perreault et al., 2016; Whatman et al., 2018), the need for more research in this sector of sports communication is apparent. This study aimed to take a step in closing that research gap by identifying barriers to soreness reporting and taking measures to try and work around those barriers in partnership with a Division I, southeastern, public university football team over the course of the 2024 season. The 2024 season’s data was then compared to data collected in the 2021-2023 seasons. Exploratory research into a Division I, southeastern, …

Tattoo Stereotypes In The Workplace: Can Being A Tattooed Female Increase Perceptions Of Hireability?, Gabrielle A. Rufrano

All Theses

There is ample research supporting that having a visible tattoo can hinder one’s chances of being hired because of the application of negative stereotypes typically associated with being tattooed. However, recent evidence has demonstrated that tattooed individuals can be positively stereotyped, and that job context can influence customer attitudes and behaviors towards them, suggesting that tattoos can benefit employees in certain job types (Ruggs & Hebl, 2022; Timming, 2017). Gender differences in this body of literature have not been thoroughly explored, but interestingly, there is conflicting evidence on the perceptions of visibly tattooed women. Across two experimental studies and a …

The Impact Of Quality Of Life And Recovery Capital On Inhibitory Control In Patients On Medication For Opioid Use Disorder, Caroline K. Jeffries

All Theses

The opioid crisis persists as a global health challenge, necessitating a comprehensive understanding of the complex interplay between psychological factors and neurocognitive responses among individuals with opioid use disorder (OUD). Two such psychological factors include recovery capital, an individual's internal and external resources to supporting recovery, and quality of life. Past work suggests that positive levels of recovery capital and quality of life may enhance individuals’ ability to regulate emotions and manage cravings. However, it is unclear how these variables are affected when buprenorphine is taken. This study investigates the influence of recovery capital and quality of life on inhibitory …

Evaluating Climate Benefits In The Conservation Reserve Program: Methane Emissions And Carbon Storage In Restored Wetlands, Annika Kuleba

All Theses

As climate change progresses, Nature-based Climate Solutions (NbCS) have emerged as a key strategy for mitigation. Historically, wetlands were drained to increase arable land area, resulting in habitat degradation and soil erosion. To address these issues, the United States Department of Agriculture (USDA) incentivizes wetland restoration under the Conservation Reserve Program (CRP), in which landowners retire agricultural land to reestablish native habitat. Although wetlands can act as carbon sinks, they are also sources of methane, a more potent greenhouse gas (GHG). Therefore, the effectiveness of wetlands as a NbCS remains under debate due to assumed high methane emissions. Wetland functions …

Exploring Antimicrobial Performance And Compostability Of A Pectin-Based Film, Jessica Hardiman

All Theses

Packaging is considered one of the most important parts of the food supply chain. Packaging affects many aspects of the food product, such as acceptability, safety, nutritional quality, and it also provides a means of communication with the consumer. Although many people are aware of the great benefits packaging provides to the food sector, fewer think about the repercussions that occur from the waste that is generated from packaging, or the waste from the food inside the package. There is little research done on the development of compostable and antimicrobial packaging, which could reduce plastic and improve food safety. In …

Application Of Remote Sensing In Mapping Callery Pear Distribution And Biomass Estimation In The Southeastern United States, Kavi Raj Awasthi

All Theses

Callery pear (Pyrus calleryana Decne. Rosaceae) is a rapidly spreading invasive species in the southeast United States (US) that hampers the function of native tree species and the forest ecosystem. Native to Southeast Asia, the species has encroached on the natural and secondary vegetation habitats of the Southern US in recent years. This study attempted to 1) map the Callery pear across the southeast US and 2) model the aboveground biomass (AGB) of individual Callery pear trees.

The study of graffiti has become a multi-disciplinary study. Historical and modern forms of graffiti offer a unique perspective on the connection people have with religious sites over the span of three hundred years. Within South Carolina, the establishment of twenty-five churches throughout the Lowcountry from 1706 to 1775 offers an understanding of people’s connection to spaces from the beginning of South Carolina’s establishment to the present day. Their beliefs are reflected throughout the space of the building as congregations have left their imprint.

In order to understand the relationship of people to the site over time, various methods were …

A Review On Treatment, Prevention, And Research Of Worldwide Parasitic Disease: Toxoplasmosis, Hannah Skinner

All Theses

Toxoplasmosis is a worldwide, yet often overlooked, parasitic disease caused by the protozoan parasite, Toxoplasma gondii. The parasite is capable of infecting humans and almost all warm-blooded vertebrates. Over a million people are infected in the United States with toxoplasmosis each year. Most infections are asymptomatic but severe cases can lead to vision impairment, neurological disorders, and congenital birth defects. T. gondii is transmitted through undercooked meat, infected feline feces, or contaminated water and soil. The burden of T. gondii infection is most notable in livestock, felines, and immunocompromised humans. Despite being a widespread disease, toxoplasmosis is neglected in …

Evaluation Of High Temperature Borehole Heat Exchangers For Thermal Energy Storage, Robert J. Mcdaniel

All Theses

The development of renewable power sources like solar panels and wind turbines is crucial to lowering greenhouse gas emissions and slowing the increase in global temperature. These sources are limited by the intermittency of power output depending on factors such as weather or time of day. Storing energy during periods of peak productivity improves the efficiency of renewable sources and makes them more competitive with fossil fuels. The excess energy can be stored underground as heat. At high enough temperatures (>150ºC) and discharge rates (>70 kW) the stored energy can be converted back into electricity. This turns the …

Thymosin Beta-4: A Novel Treatment For Acanthamoeba Keratitis, Victoria A. Murphey

All Theses

Acanthamoeba keratitis (AK) is a severe corneal infection caused by the free-living amoeba, Acanthamoeba. Both stages of its life cycle (trophozoite and cyst) cause infection, primarily in contact lens wearers. It is often misdiagnosed, leading to delayed treatment and poor clinical outcomes. Current treatment options for AK rely on anti-amoebic agents that are toxic to corneal epithelial cells. Further, no single drug can eliminate both forms of the amoeba. Approximately 30% of all AK infections require a corneal transplant.

Thymosin beta-4 (Tβ4) is a G-actin binding protein synthesized in almost all human cells, including corneal epithelial cells. Tβ4 exhibits …

In response to new drinking water regulations announced by the EPA in 2024, many municipalities will need to monitor concentrations and implement new treatments to address PFAS, a class of anthropogenic organic contaminants. A leading technology for this application is GAC adsorption due to its familiarity and availability. The adsorption of four PFAS species (PFBA, PFBS, PFOA and PFOS) to Calgon Filtrasorb400 (F400) was evaluated for a range of pH and ionic strength conditions to investigate the role of electrostatic interactions in adsorption capacity. These PFAS are all strong acids, so pH was used as a control for GAC surface …

Graph Based Deep Reinforcement Learning Aided By Transformers For Multi-Agent Cooperation, Michael S. Elrod

All Theses

Mission planning for a fleet of cooperative autonomous drones in applications that involve serving distributed target points, such as disaster response, environmental monitoring, and surveil- lance, is challenging, especially under partial observability, limited communication range, and uncertain environments. Traditional path-planning algorithms struggle in these scenarios, particu- larly when prior information is not available. To address these challenges, I propose an innovative framework that integrates Graph Neural Networks (GNNs), Deep Reinforcement Learning (DRL), and transformer-based mechanisms for enhanced multi-agent coordination and collective task ex- ecution. My approach leverages GNNs to model agent-agent and agent-goal interactions through adaptive graph construction, enabling efficient …

This research adds wastewater infrastructure with the aim of identifying …

Unsettling Femininity In Ottessa Moshfegh’S My Year Of Rest And Relaxation, Audrianna Witcher

All Theses

This thesis covers how Ottessa Moshfegh’s My Year of Rest and Relaxation critiques traditional understandings of femininity and the inadequacy of neoliberal feminism to address the systemic issues that women face. Using Lauren Berlant’s concept of femininity as a genre, this thesis traces how Moshfegh implements disgust and abjection to reject mandates of cleanliness and emotional labor that are central to traditional femininity. Moshfegh also utilizes disgust and the narrator’s attempt at a year-long sleep to resist the ideals of productivity and self-care that are central to neoliberal feminism. In employing these affects, Moshfegh resists the social structures that exploit …

When 'Weird' Means 'Dangerous': Viruses And Firewalls In Affective Polarization, Nathan J. Locke

All Theses

As traditional sources of epistemic authority face declining trust, alternative narratives have gained prominence - often leveraging the emotional and cultural resonance of seemingly simple terms. In the 2024 election cycle, the term “weird” emerged as a potent meme in American political discourse. Using a memetic perspective that incorporates elements of framing theory and Social Judgment Theory, this thesis investigates the use and reaction to “weird” and its role in shaping perception of Donald Trump, his political allies, his followers, and his opposition during and immediately after the 2024 Presidential election. The memetic perspective, which views ideas as units of …

Commodification And Objectification Of The Black Male Athlete In The Nfl, Jalen A. Terrell

All Theses

The black male body has often been viewed as a commodity in Western culture since the commodification of the black male body in the historical slave auction. Albeit slave owning ended in 1863 with the Emancipation Proclamation, it was not until 1946 that the National Football League (NFL) became integrated, and the commodification of black bodies became prevalent once again. As such, this study looks to understand how the X population from the data set for this study demonstrates the commodification of the black male body, the general discourse around the black and white male athletes, and explores the language …

Essential Components For A Uas Standard Operating Procedure Manual For State Departments Of Transportation, Nurudeen Segun Lawal

All Theses

The integration of Unmanned Aircraft Systems (UAS) within state Departments of Transportation (DOTs) has become increasingly essential for improving efficiency, safety, and regulatory compliance in transportation operations. However, the lack of a standardized approach to UAS program management has resulted in variability in policies, procedures, and implementation strategies across state agencies. This study examines how state DOTs incorporate the Association of Unscrewed Vehicle Systems International (AUVSI) Organizational Implementation Guide (OIG) 35 essential components into their UAS Standard Operating Procedures (SOPs) and identifies 13 additional components that address agency-specific operational, regulatory, and administrative needs. Through an analysis of publicly available SOPs …

Efficient Solvers And Anderson Acceleration For The Bingham Equations, Victoria L. Fisher

All Theses

This work studies two techniques utilized to solve the Bingham equations that model viscoplastic flow. An Uzawa-type iterative procedure is first analyzed and tested for poor convergence of velocity and stress. We apply Anderson acceleration (AA) to this method and show improved convergence rates for both velocity and stress. A solver utilizing regularization is introduced, and AA is also applied to display better convergence results. We propose a new method that combines these two solvers and applies Anderson acceleration.
