Design And Uncertainty Methodology In High Efficiency Filtration Media Testing, Jeremy Andrei Adriano May 2026

Design And Uncertainty Methodology In High Efficiency Filtration Media Testing, Jeremy Andrei Adriano

Theses and Dissertations

Electrospun nanofiber media are being developed as potential alternatives to conventional HEPA filtration materials due to their small fiber diameters and tunable microstructures. To support future testing of these materials, the Small-Scale Test Stand (SSTS) at the Institute for Clean Energy Technology (ICET) requires modifications to ensure accurate and repeatable aerosol filtration measurements. Electrospun filters introduce challenges including fragile media structures and uncertain filtration efficiencies that may allow particle penetration to downstream instrumentation. This work evaluates adaptations to the SSTS design to support testing of electrospun filtration media. In addition, an uncertainty framework for aerosol measurements obtained using a Scanning …


Impacts Of Structural Design On Oyster Survival And Predation In Restored Oyster Reefs, Jaden Akers May 2026

Impacts Of Structural Design On Oyster Survival And Predation In Restored Oyster Reefs, Jaden Akers

Theses and Dissertations

Restoration efforts are critical to ensure healthy oyster populations, but the high cost and marginal success rate of many restoration efforts demonstrates the need to evaluate alternative oyster reef restoration designs and strategies. To address this issue, I conducted a paired field and mesocosm study to assess the influence of structural design on oyster survival and predation. Results of the field portion of this study showed that oyster survival was greatest in short and bed-level (i.e., sitting on the sea bottom) reef designs. When assessing how design features impact oyster drill activity, elevated reefs (i.e., elevated above the sea bottom) …

This research seeks to address these gaps by examining how a pandemic impacted park usage among the older adult population (age 60+) in Memphis, TN at Shelby Farms Park. This study examines the comparison of park use during (2020-2023) and after (2023-present) COVID-19. A mixed methods approach was employed. Wilcoxon Signed Rank test was run to analyze the survey data and a significant statistical difference. …


On The Bias And Variance Of The Plug-In Estimator For Generalized Shannon’S Entropy, Shirli Salihaj Arndt May 2026

On The Bias And Variance Of The Plug-In Estimator For Generalized Shannon’S Entropy, Shirli Salihaj Arndt

Theses and Dissertations

This dissertation analyzes the bias and variance of the plug-in estimator for generalized Shannon’s entropy. The setting is discrete data where observations take categorical values and the statistical object of interest is a probability distribution on an alphabet of possible outcomes. In such problems, entropy provides a relabeling-invariant summary of dispersion, but estimation can be challenging when the number of possible outcomes is large relative to the sample size. In addition, on some countably infinite alphabets, the classical Shannon entropy may diverge, motivating alternative entropy-like targets. Generalized Shannon’s entropy is defined by applying Shannon entropy to an escort reweighting of …


The South Got Somethin' To Say!: Black Student Affairs Professionals Sustaining Equity Work Amid Dei Dismantling, Jaborius D. Ball May 2026

The South Got Somethin' To Say!: Black Student Affairs Professionals Sustaining Equity Work Amid Dei Dismantling, Jaborius D. Ball

Theses and Dissertations

Scholarship within the academy extensively interrogates the realities of Black faculty but neglects the lived experiences of Black Student Affairs Professionals (BSAPs). This omission renders BSAPs labor and experiences institutionally invisible while reinforcing the narrative of equity work being a racial obligation pushed on Black professionals rather than institutional responsibility. Although representing 15% of the higher education workforce, this gross percentage is disproportionately concentrated in lower-paying, non-exempt staff positions (e.g., service, office/clerical) rather than in decision-making authority (CUPA-HR, 2025). Despite structural marginalization and inconsistencies, institutions rely on Black professionals to bear the brunt of racialized equity labor work classified as …

Mandates Versus Capacity: Utilizing Pace To Proactively Approach Teacher Evaluation For High School Administrators In Mississippi, Jessica Paige Posey Cumberland

Theses and Dissertations

A lack of teacher support from administration remains one of the leading reasons provided by teachers leaving the classroom exacerbating the growing teacher shortage nationwide. Over the past twenty years, policies have been passed in the form of teacher evaluation systems in order to ensure support for teachers is provided and that quality educators are servicing public school students in the U.S. Oftentimes relying on already overburdened administrators in the school to provide the mandated support without the consideration of the existing environmental demands of the administrator, specifically time as a resource, the potential for administrators to cope with the …


The Development And Evaluation Of An Automated Tactical Tillage Tool To Identify And Control Weeds In Row-Crop Production Systems Using Vision-Based Machine Learning., Clara Anne Cobb May 2026

The Development And Evaluation Of An Automated Tactical Tillage Tool To Identify And Control Weeds In Row-Crop Production Systems Using Vision-Based Machine Learning., Clara Anne Cobb

Theses and Dissertations

Controlling in-field weeds in row-crop production systems is vital to the success of the operation. To control weeds, most producers use combinations of weed control strategies, including tillage and herbicide applications. Cotton production operations across the country have been trending toward conservation tillage practices in an effort to minimize soil disruption and maintain crop residues on the soil surface. This practice, in addition to the adoption of herbicide-tolerant cotton varieties, has encouraged more use of chemical herbicides. The overuse of these herbicides has resulted in an increase in herbicide-resistant weeds, making weed control difficult for farmers. This research aimed to …

Faculty Perceptions Of Transfer Students: How Characteristics And Experiences Inform Faculty Predispositions Toward Transfer Students In Senior Institutions, Tracey Ann Dubard May 2026

Faculty Perceptions Of Transfer Students: How Characteristics And Experiences Inform Faculty Predispositions Toward Transfer Students In Senior Institutions, Tracey Ann Dubard

Theses and Dissertations

Faculty perceptions of student populations have been widely discussed, but the conversation has seldom focused on the transfer student population. Because a third of community college students choose to transfer into four-year institutions, the elements of the environment awaiting them are worthy of exploration. The classroom setting is a shared experience for transfer students. Therefore, faculty can play a significant role in creating a climate of support for this population. However, the opposite may be true. Transfer students often arrive on campus to find an environment that is mostly focused on traditional students. The lack of a supportive environment may …


British Subjects "Of Ye Jewish Religion": The Negotiated Identities Of The Levy-Franks Family, Laura Miriam Drake May 2026

British Subjects "Of Ye Jewish Religion": The Negotiated Identities Of The Levy-Franks Family, Laura Miriam Drake

Theses and Dissertations

Through a series of determined choices over sixty-five years, the Levy-Franks family blended their religious identity as Jews with their claimed British socio-political identity to achieve economic success in eighteenth-century colonial New York. Through colonial records, newspapers, legal petitions, portraits and, most significantly, the letters of Abigaill Levy Franks, this dissertation examines the family’s actions taken to create a blended identity, despite the potential threat that their participation in the broader British Atlantic world posed to their religious selves. During a time in British history when religious identities were at the forefront of political debate, the Levy-Franks family created a …

Theses and Dissertations

Symphyotrichum, a plant genus traditionally treated within the genus Aster L., comprises >100 species of annual or perennial plants in the Compositae family Asteraceae. One of the most diverse genera in the southeastern US flora, the genus extends across the Americas, the Caribbean as well as eastern Eurasia. Despite its presence across the major American biomes and with distinctive floristic characteristics, several question regarding Symphyotrichum remains obscure. This research project focuses on exploring diverse aspects of Symphyotrichum systematics, biogeography and evolution. I tested three main hypotheses: (1a) Symphyotrichum originated ancestrally across Mexico and eastern North America in the Miocene ( …


Rethinking Social Disorganization In Rural America: Persistent Poverty, Institutional Fragility, And Crime, Addison Finch May 2026

Rethinking Social Disorganization In Rural America: Persistent Poverty, Institutional Fragility, And Crime, Addison Finch

Theses and Dissertations

Social Disorganization Theory (SDT) links structural disadvantage to crime through mechanisms such as residential instability, weakened social networks, and reduced informal social control in urban neighborhoods. Less is known about whether these mechanisms operate similarly in persistently poor rural communities where disadvantage is enduring rather than destabilizing. This study examines whether variation in poverty intensity predicts county-level crime in nonmetropolitan, persistently poor counties in Kentucky and Tennessee from 2016 to 2023. A balanced county-year panel (N = 344) integrates incident-based crime data with measures of poverty intensity and institutional capacity. Pooled ordinary least squares models with year fixed effects and …


Evaluation And Mitigation Of Bias And Toxicity In Open-Source Large Language Models Using Crows-Pairs And Bold, Sai Harika Gade May 2026

Evaluation And Mitigation Of Bias And Toxicity In Open-Source Large Language Models Using Crows-Pairs And Bold, Sai Harika Gade

Theses and Dissertations

This thesis evaluates bias and harmful language generation in five open-source language models and tests practical mitigation methods that do not require retraining. Two masked models are assessed with a sentence-pair benchmark for stereotype preference, and three generative models are assessed with a prompt-based benchmark for harmful continuations across demographic domains. The study uses a unified experimental workflow to compare model behavior, summarize differences across bias categories, and measure changes after intervention. Results show that the masked models favor stereotypical content above a random baseline, while the generative models usually produce low average toxicity but still show uneven risk across …


The Role Of Risk And Resilience In Psychological Distress: An Application Of The Minority Stress Model, Rachel Clair Franklin May 2026

The Role Of Risk And Resilience In Psychological Distress: An Application Of The Minority Stress Model, Rachel Clair Franklin

Theses and Dissertations

LGBT individuals experience disproportionate levels of psychological distress compared to heterosexual populations, often attributed to minority stressors, including experiences of discrimination and victimization. Guided by the Minority Stress Model, the present study examined whether social and community support moderated the relationship between minority stress and psychological distress, and whether rejection sensitivity and fear of discrimination mediated these associations. Data were collected from a sample of 251 individuals who self-identified as lesbian, gay, bisexual, or transgender in the United States. Multiple regression, moderation, and mediation analyses using the PROCESS macro were conducted to examine relationships among experiences of discrimination, sexuality-based victimization, …

For landscape architects this brings about a new challenge in designing for the …


Adaptive Channel Switching For Contention Resolution, Shafqat Hasan May 2026

Adaptive Channel Switching For Contention Resolution, Shafqat Hasan

Theses and Dissertations

Contention resolution is a fundamental problem in distributed computing, where multiple devices compete to transmit over a shared channel without centralized coordination. Classical models typically assume a single always-available channel and focus on minimizing makespan. However, modern wireless systems increasingly operate under spectrum-sharing frameworks in which access to high-capacity spectrum is opportunistic and may be interrupted by higher-priority users. These settings introduce new challenges, including asymmetric channel speeds, adversarially scheduled evictions, and non-trivial switching costs. In this thesis, we study contention resolution in a dual-channel model consisting of a slow, always-available channel and a faster channel subject to adversarially scheduled …

Development And Application Of An Edna Protocol For The Detection Of Gulf Coast Walleye (Sander Vitreus) In Mississippi, Kevin W. Jones

Theses and Dissertations

The Gulf Coast Walleye (Sander vitreus) is a genetically unique Walleye population endemic to the southeastern United States and is increasingly threatened due to habitat loss. The current distribution of this population is poorly understood, especially in the upper Tombigbee River Basin in Mississippi. We developed an environmental DNA (eDNA) sampling method for Gulf Coast Walleye by modifying an existing quantitative PCR (qPCR) assay. Our assay tested highly sensitive for Walleye DNA and presented a minimal risk of cross-amplifying co-occurring nontarget species. We then applied the assay to samples from 26 streams in the upper Tombigbee Basin and positive controls. …
