Water samples were taken from three sites in each estuary from February 2025 to December 2025. The samples were digested, filtered, then examined visually for microplastics. Plastic particles were extracted and analyzed by Raman microscopy to obtain polymer content. Results indicate …

The Secondary City: Georgetown And The Waccamaw Neck Within A Global Maritime Perspective, 1740-1850, John Paden Wilson

Theses and Dissertations

Georgetown is not and has never been the primary city on the South Carolina coast. Its harbor is shallow and muddy and its urban development lacks the commercial density found in more prominent Atlantic port cities such as New York, Boston, Philadelphia, and Charleston. Despite all indicators to the contrary, this marshy backwater outpost became the second richest port in the United States prior to 1850 through rice and indigo exportation. As a result, the port drew people, goods, and ideas from around the Atlantic. Despite its small size and limited cultural relevance, Georgetown was a regional node for international …

Guided by a conceptual framework integrating Maslow’s Hierarchy of Needs, Bridges’ Transition Theory, and Zimbardo’s Time Perspective Theory, this study sought to understand the barriers FFY encounter, the supports they find most meaningful, how they define successful independence, and the role higher education plays in that definition.

Data was collected through preliminary meetings, …

A Tail Of Consumption: Essays On Pet-Person Identities And Their Effects On Consumers, Mackenzie Micheala Volk

Theses and Dissertations

This work examines how exposure to pet-person identities — identifying as a dog person or a cat person — affects consumer behavior. Across two chapters, results show that exposure to dog-person cues increases preferences for bold and conspicuous product features through heightened desire for dominance-based status signaling. Additionally, exposure to cat-person cues activates a cat-person mindset, boosting support for inclusive businesses and policies by increasing minority support and justice sensitivity. Together, these findings suggest that subtle identity cues in the marketplace can meaningfully shape consumer preferences and social attitudes, with implications for how brands position themselves and how policymakers and …

Examining Shifts In Attitudes Toward Mathematics: A Mixed Methods Study In Undergraduate Business Calculus, Kathryn Pedings-Behling

Theses and Dissertations

Students in my non-theoretical Business Calculus course at the College of Eastshore almost never begin the class with a positive attitude towards mathematics. They are taking the course to fulfill their general education requirements in mathematics, and for most of them, this will be their last experience in a formal classroom setting with a mathematics educator. This profile of a math-reluctant student is not unique to my Business Calculus course; I have spoken with many fellow educators in similar situations who experience the same persistence of negative attitudes toward mathematics from their own students. Their attitude not only has implications …

Generalized Planning Using Language Models And Its Applications, Vishal Pallagani

Theses and Dissertations

Planning is a fundamental capability for intelligent systems, yet classical planners remain difcult to scale and generalize across domains due to their reliance on hand- engineered models, brittle search procedures, and limited adaptability. These limita- tions constrain real-world applications that require fexible reasoning, robust decision- making, and the ability to operate across diverse environments.

Large language models have emerged as powerful learners supported by their ar- chitectures and large-scale training data, demonstrating strong capabilities in tasks such as question answering, code generation, summarization, and reasoning. Moti- vated by their broad generalization abilities, I investigate whether language models can be systematically …

A Compilation Of Works For Soprano By Moravian Composers From North Carolina, Laura Kay Hutchins

Theses and Dissertations

Moravians are among the first people to compose art music for both instrumental ensembles and works for solo voice in the American colonies. However, if you examine the repertoire taught and available to students of singing, you’ll find the songs of the Moravians are notably missing. To increase awareness, narrow the gap in research, and point teachers toward solo vocal repertoire, this document provides biographical information on several Moravian composers who lived and worked in North Carolina, as well as a compilation of selected works for solo soprano. As a secondary goal, the paper also highlights the contributions of several …

Strain-Induced Oxygen Vacancy Effect On Thermoelectric Properties In Oxide Thin Films, Ebenezer Seesi

Theses and Dissertations

The development of highly efficient and cost-effective thermoelectric (TE) materials is critical for converting waste heat into electricity in advanced power generators. For high-temperature TE applications, transition metal oxides (TMOs) have attracted significant interest because they are comparatively safe, earth-abundant, and stable under oxidizing conditions where many conventional heavy-metal and chalcogenide TE materials degrade. However, the TE performance of TMOs is limited by the intrinsic trade-off between the Seebeck coefficient (S) and electrical conductivity (σ), both of which depend inversely on charge carrier concentration. This constraint limits the achievable power factor (PF = S²∙σ) and remains a central obstacle for …
