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

Drawing on techniques from educational data mining, the research addresses three key phases in the lifecycle of traditional and non-traditional students. First, it analyzes student retention using predictive classification models designed to identify individuals at elevated risk of attrition. Second, it employs temporal convolutional networks for time series forecasting, estimating aggregate enrollment levels over highly variable, finite planning horizons on the basis of partially observed data and using an asymmetric loss function. …
The South Got Somethin' To Say!: Black Student Affairs Professionals Sustaining Equity Work Amid Dei Dismantling, Jaborius D. Ball
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 …
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 …
British Subjects "Of Ye Jewish Religion": The Negotiated Identities Of The Levy-Franks Family, Laura Miriam Drake
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 …
Patterns Of Molecular Evolution Driving Reproductive And Genomic Processes In Sauropsids, Taylor Green
Patterns Of Molecular Evolution Driving Reproductive And Genomic Processes In Sauropsids, Taylor Green
Theses and Dissertations
Sexual reproduction is an important driver of genetic diversity and speciation through such forces as selection, mutation, and drift. Sauropsids are an appropriate clade to study shared molecular drivers of sexual and genomic evolution due to their genome architecture, sex determination mechanism (SDM) plasticity, and large syntenous genomic regions. Using comparative phylogenetic methods, I identify predictable patterns of selection in meiotic recombination genes and clade-specific drivers of recombination rate evolution. Then, leveraging whole genome sequencing, I demonstrate that American alligator genomes are characterized by an ancient loss of genetic diversity driven by drift and historic inbreeding. I also generate a …

Assessment Of Energy And Hydration Demands Of Farm Workers In Mississippi, Mckenzie Lynne Hargrove
Theses and Dissertations
The agricultural community in Mississippi is critical to the state’s economy and the health of its communities. Farm workers meet these needs by performing highly demanding work with long hours of labor, limited resources, and stressful environmental conditions. The purpose of this investigation was to examine and measure indicators of physiological and behavioral adaptations to the heat such as whole body sweat rate (WBSR), sweat sodium (Na+) content, urine specific gravity (USG), and fluid intake, as well as determine total daily energy expenditure (TEE) and water influx (rH2O) via the doubly labeled water technique (DLW) in farm workers during the …
Adaptive Channel Switching For Contention Resolution, Shafqat Hasan
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 …

Accelerating Defensive Cyber Operations Via Unsupervised Log Clustering And Automated Regex Template Synthesis, Charles Matthew Jones
Accelerating Defensive Cyber Operations Via Unsupervised Log Clustering And Automated Regex Template Synthesis, Charles Matthew Jones
Theses and Dissertations
Modern Security Operations Centers (SOCs) ingest millions of log entries per day, but manual parsing does not scale to the volume, heterogeneity, and rapid evolution of log formats. This dissertation investigates whether unsupervised clustering can automate the generation of candidate field-extraction templates while remaining deployable in production and feasible under realistic runtime and memory constraints. The central research question asks whether a machine-learning-assisted pipeline that proposes extraction templates for security engineer review—relative to reproducible human-authored baselines such as hand-written regular expressions—can measurably improve rule-set deployability and corpus-scale extraction quality. Improvement is quantified using four applicability metrics: Coverage Rate (CR), Exclusive …
Parhsom: A Novel Parallel Hierarchical Self-Organizing Map Implementation, Rebekah E. Lane
Parhsom: A Novel Parallel Hierarchical Self-Organizing Map Implementation, Rebekah E. Lane
Theses and Dissertations
The digital age has completely transformed the way that information is processed and stored, which makes cybersecurity a crucial field of research. Cybersecurity contains many different domains, but this work focuses on Intrusion Detection Systems (IDSs). Within the literature, Hierarchical Self-Organizing Maps (HSOMs) have been used to create trustworthy, explainable, and AI-based IDSs. However, HSOMs are trained sequentially, which means that training HSOMs on large datasets is slow. This work presents a novel parallel HSOM architecture, called parHSOM. The purpose of this research is to investigate the effect that parallel computation has on the HSOM training time. parHSOM is tested …
Reproductive Genetics Of Caenorhabditis Nematodes, Dharani U. Matharage
Reproductive Genetics Of Caenorhabditis Nematodes, Dharani U. Matharage
Theses and Dissertations
Variation in reproductive traits and genome evolution reflects the interaction between selection, environment, and life-history. In the genus Caenorhabditis, recombination rate and sperm size exhibit a striking variation between strains and species. Here, Iintegrate three projects investigating recombination rate variation and recombination plasticity in C. elegans and sperm size divergence across Caenorhabditis species. First, I quantify recombination rates in two genetically distinct strains, N2 and CB4856, with different levels of laboratory adaptation using fluorescent markers spanning across gene-rich and gene-poor regions of the chromosome IV. I identify significant differences in recombination rate between the two strains within both gene-rich and …
Body Swaps, Prophetic Dreams, And The Angel Of Destruction: Agency And Narration In Mary Shelley’S Short Stories And Revisions To Frankenstein, Meg Mcdougal
Theses and Dissertations
This thesis investigates Mary Shelley’s later bibliography, focusing on several of her short stories published around the 1831 revisions to Frankenstein. This study investigates Shelley’s techniques to present the agency of each of her protagonists through various techniques of narration, including points of view, methods of storytelling, and usage of voice. Comparing three of Shelley’s short stories creates a throughline of agency and narration in tandem with the presence of the supernatural, and this throughline can be found exclusively in the 1831 edition of Frankenstein. Through this examination, Shelley’s later edition of her most famous work can be looked at …
Using Seafloor Geomorphology, Classification Schema, And Spatial Analysis To Predict Geologic Structures, With Applications For Mars, Emma Morgan
Theses and Dissertations
This study evaluated whether seafloor geomorphology can be used to predict subsurface fault locations along the Cascadia continental margin and explored whether such relationships can be transferred to Mars. Geomorphological classification schemas such as geomorphons, bathymetric position index (BPI), slope, rugosity, aspect, and curvature were derived from seafloor bathymetry data and used as predictor variables in maximum entropy (MaxEnt) models developed separately for Pre-Pleistocene, Pleistocene, Quaternary, and active fault datasets. Model performance ranged from AUC = 0.62 to 0.67, showing moderate predictive skill, with younger fault systems exhibiting stronger geomorphic associations. A secondary analysis showed a weaker but detectable relationship …

Comparison Of Degree Attainment Between Traditional And Nontraditional Community College Transfer Students From The Beginning Postsecondary Students Longitudinal Study, Diann Mills Nichols
Theses and Dissertations
Nontraditional students have been part of higher education for over a century, yet their enrollment has increased substantially in recent decades and is expected to continue rising. Many return to college to gain credentials and skills needed for career advancement or reentry into the workforce. Despite their growing presence, nontraditional students remain less likely than traditional students to complete a degree within six years, often due to competing responsibilities such as work, family obligations, and financial strain. The purpose of this study was to compare nontraditional community college students who transferred to four-year institutions with their traditional counterparts in terms …

A Cradle To Grave Life Cycle Assessment Of Captured Landfill Methane Abatement Strategies, Joshua Caleb Richard
A Cradle To Grave Life Cycle Assessment Of Captured Landfill Methane Abatement Strategies, Joshua Caleb Richard
Theses and Dissertations
Landfill methane mitigation strategies are commonly evaluated using percentage-based leakage assumptions and linear scaling models. These approaches may misrepresent system performance at varying throughput levels and real-world operating scenarios. This thesis develops a system-level life cycle assessment framework that incorporates both fixed infrastructure losses and employs sensitivity analysis to more accurately characterize emissions from landfill gas management pathways. Three scenarios are evaluated: methane capture and flare, methane capture and combustion for electricity generation, and methane upgrading with pipeline injection as renewable natural gas. Results demonstrate that emissions models over- dependance on static factors may inadvertently lead to under-reporting and provide …

Intersection Of Food Insecurity And Housing Among Veterans And Disabled Adults, Julie Anne Stepp
Intersection Of Food Insecurity And Housing Among Veterans And Disabled Adults, Julie Anne Stepp
Theses and Dissertations
This study examines how housing tenure is associated with food insecurity (FI) among veterans and adults with disabilities, utilizing the housing-food insecurity nexus framework. Previous research documents elevated FI among veterans and individuals with disabilities, yet few studies assess housing tenure as a mechanism connecting these statuses to food hardship. Using data from the 2024 National Health Interview Survey Adult Sample (n=32,629), logistic regression models estimate the independent and interactive effects of renting, veteran status, and disability status on FI. Results suggest renters have significantly higher odds of FI than homeowners, even after adjusting for poverty status, SNAP participation, and …

Evaluating The Spatial Relationship Between Geomorphology And Subsurface Structures On The Us Atlantic Margin With Applications To Other Terrestrial Planets, Andrea Caitlyn Stiles
Theses and Dissertations
High-resolution digital elevation models (DEMs) are widely available for terrestrial planetary bodies, but subsurface structural data remain limited. This research evaluated whether surface geomorphology could predict subsurface features, specifically faults and methane seeps, along the US Atlantic continental margin as an analog site. Faults were mapped with seismic interpretation and compared with quantitative geomorphic classifications derived from 100-m bathymetry including slope, aspect, rugosity, bathymetric position index, and geomorphon classes. Maximum-entropy modelling was used to predict fault occurrences from surface data. Results indicated that specific geomorphic landforms and slopes had the strongest control on fault presence, reflected in topographic expression of …

Tracing Hazing Across Adolescence: Examining How Prior Hazing Experiences Shape Hazing Motivation And Tolerance Among Newly Initiated Ifc Fraternity Members, John Michael Vanhorn
Tracing Hazing Across Adolescence: Examining How Prior Hazing Experiences Shape Hazing Motivation And Tolerance Among Newly Initiated Ifc Fraternity Members, John Michael Vanhorn
Theses and Dissertations
Hazing remains pervasive and underreported, disproportionately affecting adolescent and emerging adult men, particularly within athletic teams and fraternity contexts. Although hazing is most often studied within collegiate organizations, many students encounter hazing behaviors prior to college, yet little is known about how these early experiences shape later hazing perceptions, motivations, tolerance, and masculine norms. Grounded in Bronfenbrenner’s Process-Person-Context-Time (PPCT) model, this dissertation conceptualizes hazing as a developmental process shaped by repeated social interactions, individual characteristics, contextual environments, and time across adolescence and emerging adulthood. Using a two-paper approach with a quantitative, longitudinal survey design, study 1 examined fraternity new members’ …
Improving And Supporting Flight Instructor’S Decisions For First Solo, Isabella Piasecki
Improving And Supporting Flight Instructor’S Decisions For First Solo, Isabella Piasecki
Theses and Dissertations
Flight instructors have the burden of determining when a student is ready for their first solo flight, and many have expressed uncertainty over their own decision-making skills during this phase of a student’s training. Prior studies have examined flight instructors’ pre-solo decisions in other countries, but no such study has been conducted with American flight instructors. For this study, current flight instructors with multiple prior endorsements for a student pilot’s first solo were interviewed to identify the more abstract concepts they use to guide their decision. Qualitative themes were identified from their experiences. Using this information, a checklist was developed …
Delayed Timing Of Spring Application Of Nitrogen In Corn, Elizabeth Mae Worley
Delayed Timing Of Spring Application Of Nitrogen In Corn, Elizabeth Mae Worley
Theses and Dissertations
Application timing of nitrogen (N) fertilizer within the corn growing season can be crucial to crop nutrient uptake and availability. A lack of region-specific timing recommendations may result in inefficient fertilizer use and inconsistent yield responses. The objectives of this study were to determine how late in the growing season a first and second N fertilizer application can be pushed until corn yield is impacted and investigate whether Growing Degree Days (GDDs) should be used as better estimate of timing for N application than calendar date or growth stage. First applications were able to be delayed until V4-V6 growth stages …
Assessing The Relationship Between Subsurface Geology And Surficial Geomorphology: Remotely Predicting Geologic Features And Geohazards Using An Elevation-Trained Machine Learning Algorithm In The Northern Gulf Of Mexico, Allison L. Wing
Theses and Dissertations
This thesis evaluates the capacity to predict subsurface geologic features and submarine landslide susceptibility using surficial geomorphology derived from bathymetric elevation data in the Northern Gulf of Mexico. Quantitative geomorphic variables including slope, curvature, aspect, rugosity, geomorphons, and Bathymetric Position Index were generated from 30-meter digital elevation models and used as explanatory variables in presence-only Maximum Entropy models. Known locations of faults, pockmarks, mud volcanoes, hydrocarbon seeps, and landslides (particularly intact scarps) were used to train and validate predictive models through k-fold cross validation. Model performance was assessed using omission rates and AUC values. Results demonstrate that specific geomorphic signatures, …
