Neural-Network-Based Modeling Of Grid-Forming Inverters, Jacob D. Levesque

All Theses

Renewable energy production has grown significantly in recent years and continues to expand, resulting in an increasing number of inverter-based resources (IBRs) in the grid. As the number of IBRs in the grid continues to grow, grid-forming (GFM) inverters are becoming increasingly popular due to their ability to regulate voltage and frequency, providing increased grid stability and enabling islanding. As GFM inverters become more widely used in power systems, accurate and efficient models of their behavior are needed for system design purposes.

Emerging advances in neural networks have led to research on computationally efficient neural-network-based (NN-based) modeling approaches for inverters. …

Between Home And Hallway: Does School Discipline And Parental Incarceration Moderate Academic Outcomes Among Justice Involved Youth?, Morgan M. Hamer

All Theses

This study examines the relationship between parental justice contact, school disciplinary action, and academic performance of juvenile justice involved youth. Prior research has found youth with parents with justice system contact and juvenile justice involved youth to be vulnerable populations. Specifically, this study examines how a youthful offender with at least one parent with justice system contact performs academically, and if this relationship is moderated by school disciplinary action. Using quantitative data from the baseline wave of the Pathways to Desistance Study (Mulvey et. al, 2004), an ordered logistic regression analysis was employed to assess whether parental justice contact predicts …

Demolition By Intent: Evaluating Charleston's Red X Placard Procedures, Enforcement Practices, And Communication Methods In The Loss Of Historic Structures, Jessica Stech

All Theses

This thesis examines whether the procedures, enforcement practices, and communication methods associated with the placement of Red X placards in Charleston, South Carolina, contribute to the demolition-by-intent of historic structures. Red X placards, also known as unsafe placards, are placed on the front façade of structurally unsafe structures by the Charleston Fire Department to inform first responders in the event of a fire or other emergency. Although these placards serve as a life-safety tool, they may influence how vacant structures are perceived by family or developer owners and the public.

Through using a qualitative approach, this thesis analyzes the outcomes …

Internal communication is an important area in organizational structure. In the NGO sector, it can be used strategically to navigate resource constraints. The main objective of this study is to highlight the importance of internal communication and its role in navigating resource dependency in NGOs in Ghana. In recent times, NGOs in Ghana have been struggling as funding drops, especially after the stop order by the US government on USAID. Using qualitative data drawn from six participants who work with NGOs in Ghana, the study identified internal communication as a foundational structure to philanthropic partnerships. Through the lens of resource …

Fluorescence-Based Quantification Of Hepatic Ldl Uptake And Donor Hepatocyte Engraftment Using Atto 700–Labeled Ldl, Victor Agustin Cortes Flores

All Theses

Familial hypercholesterolemia (FH) is an inherited disorder characterized by elevated low-density lipoprotein cholesterol (LDL-C) that increases the risk of premature atherosclerotic cardiovascular disease. In severe FH, including low-density lipoprotein receptor (LDLR), hepatic LDL clearance is profoundly impaired and many lipid lowering treatment strategies have limited effectiveness. Current advances in ex vivo CRISPR–Cas9 hepatocyte gene editing in vivo and ex vivo approaches for treatment of FH are under development.

However, a central barrier to translation is the ability to quantitatively measure the percentage of healthy gen edited hepatocytes in the liver while simultaneously assessing functional hepatic LDL handling. This thesis establishes …

Women In The Chancery Court Of Maryland From 1669 To 1679, Emily A. Cole

All Theses

This project examines women who appeared in the Chancery Court of Maryland from 1669 to 1679. This thesis used the Archives of Maryland Online and the volume of proceedings of the Chancery Court. Across the three chapters, I argue that historians have largely ignored these proceedings, and that women did not appear in court out of empowerment but rather out of legal duty and requirement. I examined how these women appeared in both their legal status and the types of positions they held. This included the life cycle women typically followed from wife to widow to remarriage. They also appeared …

Forest Overstory Mortality & Recruitment Patterns Eight Years Following Wildfire In The Southern Appalachians, Ruth Cumberland

All Theses

In this study, we investigated patterns of forest overstory mortality and recruitment eight years after wildfire in a large wildfire site the Southern Appalachians, a topic that has not been thoroughly investigated to date. With evidence that pre-fire drought promotes post-fire mortality through impaired physiological function and increased fuel consumption, unknown patterns following wildfire are important to study under shifting climate and land-use conditions. In Chapter 1, three areas of interest were investigated: (a) functional group mortality response to wildfire effects, (b) temporal differences in early (1-3 years) and late (5-8 years) periods of delayed forest overstory mortality patterns following …

Rainbow Row: Tourism, Color, And The Making Of A Civic Icon, 1930s – 1960s, Samantha E. Threlkeld

All Theses

This thesis investigates the emergence of Rainbow Row in Charleston, South Carolina, as a civic and tourism icon through an integrated analysis of visual culture, preservation governance, and material evidence. While Rainbow Row has become one of the most recognizable images of Charleston’s historic district, the chronology and cultural mechanisms through which its colorful façades were produced, interpreted, and disseminated have remained largely unstudied. This study addresses the primary research question: How Rainbow Row’s painted façades were leveraged in marketing and tourism narratives between the 1930s and the 1960s, and what those representations reveal about the construction of Charleston’s civic …

Polydactyl Precursors: Insights Into Early Tetrapod Locomotion From Polydactyl American Alligators, Trevor P. Brewington

All Theses

Several of the earliest tetrapod lineages exhibited polydactyl limbs, with seven or eight digits per limb rather than the typical five or fewer seen in extant lineages. How these digit configurations might have been used during terrestrial locomotion is unclear, given the lack of living models in which their performance can be studied and limited evidence from fossil trackways. However, polydactyly occasionally appears in natural populations of American alligators (Alligator mississippiensis), animals with body plans that broadly resemble those of early tetrapods. To test how polydactyl limbs similar to those of early tetrapods might have functioned on land, …

Rooted In Purpose: Understanding Volunteer Motivations And Preferences In University Forest Stewardship, Lydia N. Heisel

All Theses

In an era of growing reliance on community support in public lands, this study explores the relationship between volunteer motivations and preferences for engagement in university forest management. The research draws from survey data collected from visitors to the Clemson University Forest (CUF), a 17,500-acre educational and research forest in South Carolina, incorporating the Volunteer Functions Inventory (VFI) to assess six motivational dimensions alongside preferences for volunteer program structures, activity types, communications, and sustained engagement intentions.

Using quantitative segmentation analysis, this study identified five distinct motivational profiles within the CUF visitor population through k-means cluster analysis of approximately 180 forest …

Modeling Repeated Evolution Of Polygenic Traits, Marshall N. Hoskins

All Theses

Understanding the genetic composition of adaptive evolution is a longstanding and primary goal of evolutionary genetics. Despite many advances in our knowledge of trait adaptation, it remains unclear how demographic changes and repeated selection might alter the expected genetic architecture of adaptation. We used forward-in-time genetic simulations to test and observe the effects of opposing, repeated selection regimes on a polygenic trait in populations with and without changes in demography to better understand the genetic alleles that underlie polygenic adaptation. To further illuminate how natural populations might evolve, we investigated the impact of mutation effect size, the role of dominant/recessive …

Beyond The Interface: Human Perceptions Of Generative-Ai Chatbots As Conversational Partners, Browning W.E. Blair

All Theses

Generative AI (gen-AI) chatbots are becoming embedded in everyday communicative life, yet it remains unclear whether users perceive these systems as socially reciprocative conversational partners. Therefore, this study examines how young adults understand and interact with gen-AI chatbots, focusing on perceptions of conversational partnership, anthropomorphism, politeness, discomfort, and technical understanding. Guided by the CASA framework, Media Equation Theory, and the uncanny valley hypothesis, this study employed four semi-structured, online focus groups with 15 undergraduate students and recent college graduates in the United States. Findings indicate that participants did not broadly perceive gen-AI chatbots as conversational partners in the interpersonal sense. …

The Invisible Toll: Black College Women And The Intersection Of Academic Stress, Rest Deficiency And Exhaustion At Clemson University, Jomya Ford

All Theses

Leisure has been an under-explored aspect of Black women’s lives in higher education, particularly within predominantly white institutions (PWIs), where limited culturally relevant opportunities and racialized isolation shape daily experiences. Constraints around rest, rooted in racism and gendered expectations, continue to influence how Black college women navigate academic pressure, deficiency narratives, and exhaustion. Guided by intersectionality, this qualitative study draws on semi‑structured interviews with Black undergraduate and graduate women at a PWI to explore how cultural upbringing, institutional climates, and internalized expectations shape their definitions and practices of rest. Findings show that while participants recognize rest as necessary, they rarely …

Elizabeth Blackwell And Her Heirs: America And Great Britain’S First Female Physicians, Charleigh E. Sprawls

All Theses

This thesis seeks to explore the varying historical themes surrounding America and Great Britain’s first female physicians. Studying 1849-1894 allows for the exploration of not only the nineteenth century, but also the Gilded Age and Progressive Eras of American History. Professionalization played a crucial role in the lives of these women, as it drastically altered the makeup of the medical career, making it more difficult to enter and become qualified as a licensed physician. There were significant barriers to entering the medical profession for these women, including elements like race, class, and most importantly, gender. This thesis argues that while …

Understanding The Relationship Between Property Neglect And Subjective Well-Being: How Redevelopment Can Strengthen Community Identity In Anderson, South Carolina, Andrew Karriem

All Theses

Neglected and abandoned properties do more than just harm the physical appearance of urban cities. They contribute to the decline in emotional well-being among the residents that live near them.

The "Confidential Whispers" Of Charles Francis Adams From His Teens Through Marriage At Age 22, Mitchell Jay Freedman

History ETDs

The early diaries and letters of Charles Francis Adams (1807-1886) reveal, contrary to previous scholarship, a passionate and sensitive young man engaged in multiple social activities with male and female friends and family, as well as enjoying licentious and respectful personal relationships with women. CFA was strategic with whom he was friendly or reserved, rooted in his hostility towards “hangers-on” and “hypocrites.” CFA also read widely both fiction and non-fiction with an affected sensitivity consistent with his desire for a literary-oriented life, the latter most reflected in his later curating his forebears’ papers. CFA’s early life experiences led CFA to …

The Prevalence Of Amenorrhea In Relation To Red-S Syndrome Among Various Sports In Collegiate Female Athletes, Ruby S. Holland, Marilou D. Shreve

The Eleanor Mann School of Nursing Undergraduate Honors Theses

Background: RED-S is a common risk factor for amenorrhea in female athletes. Athletes that compete in high-intensity sports or without adequate caloric intake, are at risk for low energy expenditure which may disrupt hormonal balance. As development of RED-S is a well-established risk factor for amenorrhea, early detection and correction is crucial to prevent long term health consequences.

Purpose: The purpose of this research is to explore if there is a correlation between RED-S score and amenorrhea in female athletes.

Methods: An online survey was distributed to approximately 220 female athletes at the University of Arkansas using Qualtrics. The 69-question …

Campaign Finance And Democratic Integrity: Studying The Effects Of Campaign Finance On Elections, Abigail C. Johnson

Using data collected from the Stanford Database on Ideology, Money in Politics, and Elections (DIME) this paper examines the connection between campaign finance results in independent expenditures. Focusing on 2022 and 2024 United States Senatorial election cycles, this research investigates whether or not female and male senatorial candidates receive higher or lower rates of supportive and opposing funding and how such funding effects the electoral outcomes of female candidates. Through logit regression analyses and descriptive statistics, like histogram and distribution graphs conducted in RStudio, this research measures how financial backing from outside groups affects probability in Senatorial primary electoral …

Creating A Gis-Based Site Suitability Index For A Major Sports Stadium In Kansas City, Theodore E. Blair

Political Science Undergraduate Honors Theses

There are many considerations taken when siting major sports stadiums. Most literature, though, has focused on the political and economic considerations, the negative outcomes of using public money for private projects. However, geographic considerations play a major part in deciding where to site a stadium. These considerations are wide-ranging and can change with the times. This thesis determines ten modern site suitability criteria, and with them, creates a site suitability index using GIS to determine and quantify more and less suitable areas for stadium development. It applies this index to the Kansas City area, as the city is currently in …

Effects Of Beaver Dams On Components Of Riverscape Health And Biodiversity In The Great Basin, Cashe C. Rasmussen

All Graduate Theses and Dissertations, Fall 2023 to Present

Networks of rivers and their floodplains (i.e., low-lying areas adjacent to rivers and streams that could plausibly flood) have been degraded, reducing the availability of freshwater and habitat for people and wildlife. Therefore, land managers are pursuing cost-effective restoration strategies, including partnering with beavers (Castor canadensis), to promote the health of these ecosystems and associated benefits. However, our understanding of beaver-mediated restoration benefits remains incomplete. Here, we compared locations along streams with and without beaver dams to measure the benefits of beavers in the Great Basin of the Western United States. We measured the effects of beaver dams …

Girl Grammar: A Syntactic And Pragmatic Analysis Of Girl And Miss Girl, Evelyn A. Powers

Senior Honors Papers / Undergraduate Theses

Based on observation, personal interaction, and informal interviews/linguistic judgements, this thesis presents the unique and asymmetrical grammaticality patterns of the terms Girl and Miss Girl. To account for these asymmetries, I provide a syntactic framework rooted in Minimalism and Rizzi’s (1997) expanded CP hypothesis, alongside a pragmatic explanation based on Barros and Frank’s (2023) attentional maintenance and attentional shift paradigm.

Miss Girl behaves as a typical R-expression when used as a 3rd person subject, but Girl has a very restricted distribution, inconsistent with either R-expressions or pronouns (it is acceptable as the subject of a main clause, ungrammatical in object …

Grazed Pasture Effects On Greenhouse Gas Emissions In The Ozark Highlands, Tyler Buchanan

Graduate Theses and Dissertations

In the United States (US), grazinglands serve as the main foundation for the livestock industry, and, in Arkansas specifically, pastures are essential for rotational grazing and dairy operations. Climate change is increasingly becoming a concern in the agriculture industry, largely caused by anthropogenic activities increasing greenhouse gas (GHG) concentrations in the atmosphere, at least partly due to the nutrient recycling that occurs from animal manure additions in grazinglands. Therefore, quantifying GHG emissions from pastures is essential to better understanding the impacts of grazing on the environment. The objective of this study was to quantify and evaluate the potential effects of …

Dissecting The Complex Genomic Landscape Underlying Oxidative Stress Resistance Using Natural Variation In Yeast, Sonali Lakshika Anne Lenaduwe

Graduate Theses and Dissertations

Stress is experienced across the tree of life. Survival in fluctuating environments depends on a robust genetic architecture. This dissertation examines the genetic and metabolic determinants underlying one such adaptive response: cross-protection. Leveraging natural variation in the stress responses of budding yeast, Saccharomyces cerevisiae, I examine the genetic variation contributing to ethanol-induced cross-protection against oxidative stress. Acquired stress resistance, in which mild pre-exposure improves survival to subsequent stresses, is prevalent across diverse organisms and can involve both same-stress and cross-protection. Using high-throughput bulk segregant analysis (BSA-seq) and advanced intercross mapping populations derived from natural yeast isolates, I identify quantitative trait …

Every Why Hath A Wherefore, Harrison Baxley

Graduate Theses and Dissertations

This thesis investigates techniques learned in classes at the University of Arkansas that would prepare me for my thesis role as both Dromio twins in The Comedy of Errors. The fast-paced production required a demanding performance from me mentally and physically, with rapid changes between each character. This project breaks down developmental training from One Person Show and Acting Studio classes that would prove essential to my thesis role. The result of this project has led to a toolbox for approaching a career in clowning, multi-character performance, and audience connection.

Graduate Theses and Dissertations

This thesis documents the lighting design process for The Trojan Women at the University of Arkansas, exploring how light can hold space for grief, devastation, beauty, and survival. Guided by the central conceptual image of “flowers burning in a garden,” the design sought to balance fragility and destruction allowing moments of tenderness to exist within the wreckage of war. This document reflects on research, collaboration, conceptual development, drafting, cueing, and rehearsal-to-performance evolution. It evaluates the emotional and visual effectiveness of color, angle, texture, and rhythm in shaping audience experience. Production photographs, the light plot, and cue paperwork are included to …

An Assessment Of The Basihyal And Its Functional And Ontogenetic Relationships To The Masticatory Apparatus In Primates, Parker Mitchell Taylor

Graduate Theses and Dissertations

The hyoid is central to many important functions such as feeding, vocalization, and breathing. However, primate hyoid morphology has been widely understudied compared to other aspects of craniofacial morphology. This dissertation aimed to bridge gaps in the current understanding of primate hyoid morphological variation and the hyoid’s relationship with mandibular morphology. Using microCT, diceCT, and three-dimensional geometric morphometric methods, this work details broad taxonomic variation of basihyal shape, resting hyoid position, and suprahyoid muscle architecture in primates, and assesses such variation for the effects of phylogeny, allometry, and covariation between these elements and mandibular shape. These analyses were also conducted …

Mechanisms Of Bacterial Glucokinase Inactivation Through Site-Specific Lysine Modification And Chemical Inhibition, Joseph Robert Will Andrews

Graduate Theses and Dissertations

Glycolysis and related metabolic pathways are controlled by various post-translational modifications (PTMs) that affect enzyme activity and metabolic flow. In E. coli, glucokinase (GLK) sits at the crossroads of glycolysis and the pentose phosphate pathway and carries out the first committed step of glycolysis: ATP-dependent phosphorylation of glucose. While it's known that glucose binding causes GLK to close its domains, how phosphate binding, lysine modification, and small-molecule inhibitors regulate GLK's shape and function is still not fully understood. Here, I combine structural biochemistry and enzymology to figure out how phosphate binding, specific mutations, and chemical inhibitors affect E. coli GLK. …

An Evaluation Of Leading Indicators In The Construction Industry And Their Relationship With Incident Rates, Kitti Miller Whalen

All-Inclusive List of Electronic Theses and Dissertations

Improving safety programs has been a focus of organizations for decades. Historically, focus has been directed towards lagging indicators such as recordable incident rates and experience modification rate (EMR). While these remain beneficial, they are only one component of the broader framework. In recent years, companies have started to examine what occurs prior to an incident, which are known as leading indicators. The research into leading indicators is promising, however research into the area is limited. The focus of this study is to identify which leading indicators are most strongly associated with improved incident rates in the construction industry specifically. …

Grace Under Pressure: An Analysis Of School Administrator Personal And Professional Stress And Self-Efficacy, Andrew Mcdaniel

All-Inclusive List of Electronic Theses and Dissertations

Indiana public school administrators are one of the most important factors for a school’s academic success. If those administrators are effective, they can help maintain an excellent school’s academic success or perhaps even turnaround a failing school. Without a doubt, their performance is critical for a school’s success. If they have confidence in their ability to help create positive outcomes, their school can achieve great things. Unfortunately, assistant principals and principals are facing significant challenges, not only from schools, but also at home. How do these personal and professional stressors affect their sense of self-efficacy? The purpose of this study …
