Linking Environmental Change, Microbial Community Assembly, And Function During A Novel Marine Phytoplankton Bloom Using Multi-Omics, Madison Renée Hurley

Doctoral Dissertations

Phytoplankton are central to marine ecosystem functioning, driving primary production, nutrient cycling, and higher trophic level dynamics. In the spring and summer of 2023, the Gulf of Maine experienced an unprecedented bloom of the dinoflagellate Tripos muelleri, reaching densities exceeding 50,000 cells L-1, an order of magnitude higher than previously recorded, and disrupting the region’s typical spring diatom-dominated succession. This bloom provided a unique opportunity to examine the metabolic strategies, ecological interactions, and environmental drivers underlying the bloom persistence and decline. An integrative approach was used, combining 18S and 16S rRNA amplicon sequencing, pigment and image analysis, network modeling, functional …

J.R.R. Tolkien’S Creation Of The Modern Fantasy Genre As A Response To Modernity By Way Of A Return To A Past Inspired By The Middle Ages, As Revealed Through The Creatures Of Middle-Earth, Regarding Race, Gender, Empire, And Religion, Jonathan Levitt

Doctoral Dissertations

Fantasy authors existed well before and during J.R.R Tolkien’s time, but he brought a new gravitas to the genre, building upon but disposing of and reconceptualizing conventional notions (such as the presence of fairies) to earn his moniker as the father of the modern fantasy genre. Although Tolkien’s stories are inspired by Northern myths, the world he creates is to be understood as historically real, as it incorporates authentic linguistic and cultural underpinnings of a society informed by his experience as a philologist and professor of Anglo Saxon. The intensity and longevity of Tolkien’s influence on the literary world and …

Who Works From Home, What Is It Worth, And Where Do They Live? Occupational Classification, Work Arrangement Preferences, And Residential Location Choice, Logan Robert Malone

Doctoral Dissertations

This dissertation examines work-from-home (WFH) arrangements through three complementary lenses: occupational feasibility, worker preferences, and residential location choice. The first chapter develops a continuous tools-based measure of WFH potential using the Department of Labor's O*NET Tools and Technology Supplement, which documents the tools used in each occupation. By categorizing tools according to their consistency with remote work and aggregating to the occupation level, I construct a measure that closely aligns with existing classifications while offering finer-grained distinctions than the binary categorizations common in the literature. The tools-based measure agrees with a widely cited task-based measure for approximately 80% of occupations …

Neutral Giant: The United States And The Costa Rican Civil War Of 1948, James Irving

Doctoral Dissertations

This dissertation is a narrative microhistory of American diplomacy during Costa Rica’s transformative 1948 civil war. Emerging out of a contested presidential election, the war pitted the Costa Rican government of Teodoro Picado and its communist allies against an anticommunist, nationalist rebel movement led by José Figueres in a monthlong fight for political power. While existing histories of American policymaking have concluded almost unanimously that the United States intervened to support the rebels as part of its Cold War strategy in Latin America—labeling the civil war a precursor to the more infamous coup in Guatemala in 1954—this dissertation seeks to …

The Bank Of North America And The Making Of American Public Finance In The Confederation Era, Arya Georgina Martinez Arellano

Doctoral Dissertations

This dissertation examines the history of the Bank of North America, the first charteredbank in the United States, as a foundational experiment in American public finance during the critical decade between the American Revolution and the founding of the Bank of the United States in 1791. Historians have often interpreted the Bank either as an extension of Robert Morris's career or as a precursor to Alexander Hamilton’s federal financial system. By shifting the focus from individual actors to institutional practice, this project demonstrates how the Bank of North America functioned as a proto-national financial institution in a political environment where …

Performance-Based Assessment Of Asphalt Overlay Cracking With Laboratory And Field Data, Meisam Khorshidi

Doctoral Dissertations

Efficient and effective rehabilitation of existing pavements is a continuing priority for transportation agencies seeking to maintain safe, reliable, and cost-effective networks. Asphalt overlays are widely used to restore ride quality and extend service life of both asphalt and concrete pavements; however, their long-term performance is often limited by thermal and reflective cracking. These distresses accelerate moisture infiltration, increase maintenance demand, and shorten overlay life, especially in cold-climate regions. Ensuring that overlay designs adequately account for structural configuration, traffic, climate, subgrade conditions, and mixture-level fracture resistance is therefore critical to avoid premature failure and excessive life-cycle costs.This dissertation advances performance-based …

MUSC Theses and Dissertations

Disparities in patient portal use undermine equitable chronic disease management, particularly for adults with diabetes in rural and historically underserved communities. This explanatory sequential mixed-methods study examined the associations among trust in the healthcare system and patient portal use among U.S. adults, using nationally representative data from the Health Information National Trends Survey (HINTS) 2023 (N = 3,711), supplemented by semi-structured interviews with frontline healthcare providers. Bivariate analyses revealed that adults with diabetes reported lower trust (83% vs. 86%, p = 0.003) and lower portal use (62% vs. 66%, p = 0.014) compared to those without a diagnosis. Multivariate logistic …

Exploring Social Emotional Learning Competencies In Middle School Theatre Education, Katherine J. Mullins

Honors Theses

Social Emotional Learning (SEL) is a method of education in which students are taught to grow in multifaceted ways. Students learn and grow as more than just students in their respective subjects, they grow in emotional intelligence, empathy, and interpersonal skills as well. SEL is not always easy to incorporate into teaching practices, but it tends to lend itself well to a theatre education setting. In a middle school specific setting, SEL and theatre-based activities yield positive results in student competencies both in and out of the classroom. In this research, through comparative analysis and reflective inquiry, I aim to …

Expanding The Vocabulary Of Staff Notation By Notating The Vocal Instrument, Ryan J. Berry

Honors Theses

The aspects of vocal music performance that are often the most engaging, expressive, and creative cannot be conveyed with the established vocabulary of staff notation. Consequently, discussion of artistic choices is limited to oral or written-word formats that are neither internationally interpretable or widely shared. This research proposes a remedy by creating notation symbols for the larynx, tongue, and formants so the movements of a singer's instrument can be described in staff notation. These symbols, along with the International Phonetic Alphabet, were applied to four performances to highlight specific artistic choices. Additionally, this paper discusses the history of vocal sheet …

Equal Protection Under The Law: Constitutionality Of Current And Proposed Anti-Lgbtq+ Legislation In Tennessee And Its Potential Impact On Business, Henry J. Kalla

Honors Theses

In recent years, the Tennessee General Assembly has become a battleground of sorts for bills attempting to police the treatment of LGBTQ+ individuals. Multiple laws that impact LGBTQ+ citizens have sparked debate as interested parties on all sides seek to clarify the scope of equal protection, religious freedom, and free expression in this evolving age. Federal law has statutes in place that prohibit discrimination against individuals based on certain protected characteristics, but sexual orientation or transgender status are not explicitly among them. The states have interpreted this ambiguity as providing them the freedom to pass their own civil rights legislation …

Exploring The Impact Of Poverty On Financial Literacy: The Role Of Parental Education In College Student Financial Behavior, Zoe Williams

Honors Theses

Many college students experience financial stress, yet financial hardship is often explained as a simple lack of financial knowledge. Recent research suggests that how students are socialized around money may matter just as much as what they know. In this study, I examined whether parental education, specifically first-generation college status, changes the relationship between household income and financial health among undergraduate students at a regional public university in the southeastern United States. Participants included 204 undergraduates recruited through the university research pool. Students reported household income (categorized as < $50,000 or >$50,000), first-generation status, and financial behaviors. Financial literacy was measured using an …

Romantasy's Inevitable Lasting Legacy, Devon T. Gibson

Honors Theses

The “romantasy” subgenre of YA literature has become influential for its novel combination of romance and fantasy as well as its popularity on Booktok, the book-based subsection of the popular social media app, Tiktok. This connection has become somewhat infamous in popular culture and has been underresearched due to how recently both concepts became significant forces within the publishing industry. This thesis argues that romantasy is a novel and lasting YA subgenre that is not dependent on Booktok to maintain it. The analysis of Sarah J. Maas’ A Court of Thorns and Roses (2015) and Rebecca Yarros’ Fourth Wing (2023) …

The Culture Of The Convent: How Recruitment Shapes Success In Religious Life, Elizabeth A. Minneci

Honors Theses

Catholic nuns in the United States have experienced a substantial decline in membership, with an 80% decrease in new members from 1965 to 2023 (CARA, 2023). Sisters impact their communities in a multitude of ways, often through education or volunteerism efforts (CCUSA, 2026; Levin, 2011; Sisters of Mercy, 2025). Previous research on Catholic nuns has not qualitatively explored Catholic nuns’ recruitment efforts, with most research providing quantitative data insights (CARA). Thus, the purpose of this study is to identify the recruitment methods convents utilize to identify pain points and avenues for improvement. Seven religious sisters were recruited for this study. …

The Ethical Imperative To Shift Toward A More Equitable Literary Education, Eleanor L. Bryant

Honors Theses

Choices governing canon formation have material, emotional, and intellectual consequences. Within canon formation, authors of different social identities, consistent with macrosocial power differentials, are unequally valued and shape cultural consciousness about which texts are aesthetically and intellectually valuable. It’s important to recognize canon formation as a process of unequally distributing cultural capital and knowledge production. The strategies and imperatives outlined here are basic first steps toward utilizing the classroom as a site to counter misogyny, racism, classism, colonialism, and homophobia. This project aims not only to deepen understanding of the sociological conditions of canon formation but also to impose an …

Toward An Understanding Of Social Marketing’S Influence On Alcohol-Related Behaviors In College Students: Health Promotion Strategies For College Campuses, Lily K. Richards

Honors Theses

Alcohol use among college students remains a persistent public health concern, influenced by a complex interaction of social, environmental, and behavioral factors. This literature review examines the prevalence of alcohol consumption in college populations, the associated short-term and long-term health consequences, and the role of social norms, peer influence, and environmental context in shaping drinking behaviors. Research consistently demonstrates that alcohol use is deeply embedded within college culture, where normative misperceptions and peer dynamics contribute to increased consumption. (Perkins, 2002; Borsari & Carey, 2001; Hingson et al., 2017). In addition, environmental factors such as alcohol availability and targeted marketing further …

Salt-Dependent Purification Of Green Fluorescent Protein Via Hydrophobic Interaction Chromatography, Katie L. Collins

Honors Theses

Green fluorescent protein, GFP, is a widely used fluorescent reporter, and its purification provides a clear model for studying downstream bioprocessing. This thesis investigates how binding-buffer salt strength affects GFP retention and elution during hydrophobic interaction chromatography, HIC, by comparing three conditions (1.0×, 0.8×, and 0.6×). GFP-expressing E. coli were lysed and clarified, and the lysate was purified on HIC columns; collected fractions were evaluated qualitatively under UV illumination to track fluorescence distribution. Results showed a salt-dependent trend in which higher salt improved retention and shifted fluorescence toward later elution fractions, while reduced salt weakened hydrophobic interactions and increased earlier …

Community Resilience And Response To Salinity Gradients In Streams Flowing Into Biscayne Bay, Florida, Sebastian M. Jimenez

Honors Theses

Salinity is a shaping force of aquatic biodiversity, and ongoing climate change and unsustainable water-management practices are causing salinity-induced stress across coastal ecosystems. Meiofauna are small (45-1000 μm), taxonomically diverse aquatic invertebrates that are vital to ecosystems and highly responsive to environmental disturbances, making them ideal for assessing the effects of changing salinities on community structure. This study investigated how meiofaunal biodiversity (ASV richness, Faith’s phylogenetic diversity, and community composition) responded to natural salinity gradients along streams flowing into Biscayne Bay, South Florida, which is a region particularly vulnerable to salinization due to sea-level rise, altered hydrology, and watershed modification. …

(Human)Ities In The Field Of Business, Emma M. Bitting

Honors Theses

Business is often seen as a field driven by numbers, but it is fundamentally powered by shared narratives, such as branding and mission statements. Increased optimization and efficiency has resulted in industries stripped of their humanity, leaving professionals interpersonally deficient. In an increasingly competitive workforce, one’s humanity has become a primary differentiator from the competition (artificial or otherwise). The division between the humanities and business has become a professional liability apparent to any observer, yet it is rarely addressed as the systemic failure it has become. This very divide increasingly hinders progress, rather than serving as the specialization of fields …

Improving Learning Habits In High School Ela, Alexander Sinn

Masters Projects

Students lack the habits and skills to process and apply what they have learned. In their secondary education, they are not developing the traits that help them succeed in college courses. Students are not explicitly taught note-taking and other study skills needed to succeed in core academic areas, English Language Arts (ELA) in particular. To address the needs of students, curriculum must incorporate expectations for students in self-efficacy and self-regulatory areas of learning. In the secondary ELA classroom, students should be provided opportunities and experiences to develop good habits. These should be requirements of 9th and 10th grade curriculum. The …

Beat Behind The Bark: Investigating The Effects Of Music Tempo On Canine Physiological And Psychological States, Marley Lanier

Honors Theses

This study explores how the tempo of music, measured in beats per minute (BPM), affects dogs' heart rate and oxytocin levels, adding to past research that shows that music affects physiological and behavioral states in dogs. Being able to understand these effects holds practical implications for improving overall well-being in canines in environments such as homes, shelters, and clinical environments. Using a within-subjects design, the dogs were exposed to slow and fast versions of one instrumental track, along with a white noise baseline condition before each randomized condition. Heart rate was recorded continuously throughout the session, and oxytocin saliva samples …

Bottles, Butterflies, And Biomass: Recycled Glass Sand, Microbial Additions, And Herbivory Effects On Milkweed Growth, Kealey Skinner

Honors Theses

Plant-soil-microbe interactions are integral components of ecological networks and drive ecosystem function from the bottom-up. Whereas herbivores regulate ecosystem function from the top-down, having opposing and potentially complementary effects on ecosystem function. My thesis sought to understand how below-ground microbial communities contribute to herbivore preference and plant biomass across varied soil substrates. My thesis asked: how do substrate and soil microbial communities influence herbivore preference and plant biomass accumulation on swamp milkweed (Asclepias incarnata)? To address this question, seedlings of A. incarnata were sown in 2.5 cm wide × 10 cm deep pots filled with either natural beach sand or …

Comparative Investigation Of Bacterial Adhesion On Medical Device Thermoplastics, Dev V. Mehta

Honors Theses

This project will focus on determining if differences in bacterial cell wall composition influences adhesiveness to thermoplastic materials used to construct patient orthotic splints. Bacteria with decreased adhesion are unable to remain bonded to orthotic splints, increasing its ability to transfer to a patient’s wound, leading to an infection. Antibiotic resistant bacteria used in this investigation included gram-positive cocci vancomycin-resistant (VRE) Enterococcus faecalis, methicillin-resistant Staphylococcus aureus (MRSA), and gram-negative rods extended-spectrum beta-lactamase (ESBL) Escherichia coli and Pseudomonas aeruginosa. Each test bacterium is a major pathogen causing healthcare-associated infections (HAIs). Saline, artificial perspiration, and ascites fluids were used to determine the …
