Evaluating Nutrient Limitation Of Phytoplankton Growth In North Inlet Estuary, Sc, Catherine Schlenker

Theses and Dissertations

The biolimiting nutrients nitrogen (N) and phosphorus (P) are vital components of molecules essential to life. In marine systems, N:P ratios tend to follow the “Redfield ratio” of 16:1, which is often used to infer nutrient limitation of phytoplankton biomass. Traditionally, estuaries are thought to be N-limited (N:P < 16), but there have been increasing instances of P-limitation (N:P > 16) in coastal waters worldwide. Over the last few decades, nutrient loading in North Inlet Estuary (NIE) has changed such that dissolved inorganic nitrogen (DIN):dissolved inorganic phosphorus (DIP) ratios have increased by ca. 130%. This increase suggests that the estuary may be transitioning to N and P colimitation or primary P-limitation. We …

Developing A Hierarchical Digital Twin Framework For Dc Microgrid Implementation, Khari Sado

Theses and Dissertations

This research introduces a hierarchical digital twin framework for DC microgrids implementation, particularly those utilized in naval power systems. Unlike traditional digital twins, this hierarchical digital twin structure offers a layered perspective. Hierarchical digital twin design promotes computational efficiency by distributing computational burden across a layered configuration that integrates lower-level digital twin blocks with a system digital twin. The layered approach breaks down complex systems into smaller manageable units that can be examined individually and collectively. Central to this strategy is the adoption of a multi-domain and multi-functional technique through the integration of the digital image framework. This allows the …

Sustainability Of A State, District, And School Professional Learning Community, Gertrude Jones Black

Theses and Dissertations

In this study, I explored professional learning community sustainability at the school, district, and state levels. Researchers have found that professional learning communities are a means of effective professional learning for teachers and a vital factor in increased student achievement. However, there is very little multi-case research involving the sustainability of professional learning communities. This multi-site case study extends the research on this topic. I used qualitative methods to clarify my understanding of the phenomenon of sustainability of PLC communities. I investigated how the PLC members’ stances and actions, perceptions of school culture, and commitment to lifelong learning impacted a …

Tax Client Goals, Regulatory Pressure, And Professional Decision-Making, Spenser G. Seifert

Theses and Dissertations

Drawing on goal theory, I illuminate how client preferences become internalized goals for tax professionals and how these client goals influence the motivated reasoning and ultimate decision-making of tax professionals. Using this theoretical framework, I then utilize an experiment to explore how the presence of salient situational factors – goal specificity, goal progress, and regulatory pressure – influence tax professionals’ decision-making. The results suggest that, as a result of their roles as both client advocates and CPAs, tax professionals default to non-specific “do your best” goals regardless of client preference specificity. Additionally, I find that increased regulatory pressure may curb …

Bass-Triadic Cadence Formulae In Melchior Neusidler’S Original Compositions From Il Primo (-Secondo) Intabolatura Di Liuto, Christopher Mcdonald

Theses and Dissertations

There was a paradigmatic shift in the discourse surrounding lute music between the early sixteenth and seventeenth centuries. The lute treatises written by early sixteenth-century German lutenists, such as Hans Judenkünig, Hanse Gerle, and Hans Newsidler, focused on technical directives that support a linear conception of music. However, lutenists active in the late sixteenth and early seventeenth century, such as Matthaeus Waissel and Jean-Baptiste Besard, describe technical accommodations for vertically conceived structures. Contemporaneously, at the turn of the seventeenth century, the discourse on bass primacy and triadic structures developed from an undercurrent, cast in the shadow of counterpoint treatises, to …

Deconvolving Provenance Signatures Of Pliocene-Pleistocene Coastal Loess Deposits Along The Atlantic Margin Of Argentina, Will Robert Quanrud

Theses and Dissertations

Dust derived from southern South America provides critical nutrients for autotropic marine biota in the South Atlantic Ocean, such that fluxes of wind-blown sediment may ultimately affect the concentration of atmospheric CO2. Expansive sand, silt, and loess deposits are exposed in Central Argentina, recording millions of years of eolian processes; however, the provenance and transport pathways of this dust remains unclear. Coastal loess deposits ranging in age from Pliocene to upper Pleistocene are present along the Atlantic margin of Argentina and provide information on sediment transport pathways for the last 4 million years. Nine samples of loess were collected and …

A Formative Process Evaluation Of Social Care Programming In A Health Care System Serving A Predominantly Rural State, Samuel Bethel

Theses and Dissertations

Health and social care continue to integrate, but relatively little is known about how social care is designed, implemented, and maintained across the health care continuum. This is especially true for health systems serving rural and under-resourced communities. To fill these gaps, this dissertation project applied formative process evaluation methods to a single case study of the largest health care system serving a predominantly rural state and its integrated social care programming. Data were collected from in-depth, semi-structured interviews following a purposeful and snowball sampling method among key informants for the design, implementation, and maintenance of social care programming as …

Businesses Or Beneficiaries: The Submerged Consequences Of Workfare Policy Design, Morgan Alexander Lowder

Theses and Dissertations

This dissertation critically analyzes the policy association between the Supplemental Nutrition Assistance Program (SNAP) and the Work Opportunity Tax Credit (WOTC), and in doing so, sheds light on the employer-uplifting design of the U.S. welfare state. I examine this association in three stand-alone Chapters with the intent of answering the following questions: 1) Is the SNAP-WOTC association mutually beneficial to SNAP recipients and the employers that access the WOTC; 2) Is the SNAP-WOTC association truly intended to be mutually beneficial; and 3) What are the perceptive consequences of revealing how SNAP benefits employers through the WOTC. Using both quantitative and …

Exploring Heat Variations In Columbia, South Carolina, Michael Graeme Hohlfeld

Theses and Dissertations

As the leading cause of weather-related fatalities in the United States, the concept of heat as a hazard has been studied for decades, especially in the urban environment. Urban heat island research is limited by the fact that most investigate land surface temperature rather than air temperature and other variables that affect human comfort including humidity. This thesis utilizes a public network of weather stations in Richland County, South Carolina to investigate differences in heat between the city of Columbia, and more rural parts of the county. The study period was June, July, and August of 2022. Results indicate that …

Generalizations Of The Graham-Pollak Tree Theorem, Gabrielle Anne Tauscheck

Theses and Dissertations

Graham and Pollak showed in 1971 that the determinant of a tree’s distance matrix depends only on its number of vertices, and, in particular, it is always nonzero. This dissertation will generalize their result via two different directions: Steiner distance k-matrices and distance critical graphs. The Steiner distance of a collection of k vertices in a graph is the fewest number of edges in any connected subgraph containing those vertices; for k = 2, this reduces to the ordinary definition of graphical distance. Here, we show that the hyperdeterminant of the Steiner distance k-matrix is always zero if …

“That Desolate Section Of Dixiecrats And Hookworms”: The Rise And Fall Of The Cio In Sumter, South Carolina, 1927-1950, Stephen Malenowski

Theses and Dissertations

In March of 1942, the Williams Furniture Company of Sumter, South Carolina signed the first union contract in Sumter County history, the Congress of Industrial Organization’s (CIO) United Furniture Workers of America Local 273. This contract provided the CIO with one of their largest victories in all of South Carolina and helped create a sense of hope that the CIO could win organizing battles in South Carolina. Despite the optimism, unionization failed to spread across Sumter County during the postwar Operation Dixie organizing campaign. This thesis looks to answer why the Southern drive failed in Sumter. Local 273 did not …

(Re)Imagining Decolonial Cookbooks After Deforestation, Kamran Shams

Theses and Dissertations

Food, like most else, is fundamentally changed by colonization. It is not just the aftermath of colonization, the settlement, that changes food—it is the act of colonial infiltrating itself. Such is the case made by Fernando Ismael Quiñones Valdivia in “Colonial Imaginations: Solitude in the Cartas y Relaciones of Hernán Cortés”—though not for food but for colonized societies broadly. More specifically, he contends that a new epistemological possibility arises when colonizer regards land as an object to be conquered, which precedes the epistemological articulation of subject/object divide. His article supplies a framework for thinking about coloniality so that a close …

Environmental Implication Of Environmental Disclosure, Jie Lian

Theses and Dissertations

Recent environmental incidents and disasters have intensified awareness and concerns about environmental issues, making the reduction of the private sector’s environmental impact a pressing necessity. The path to better environmental performance depends on enhancing environmental disclosure. While an increasing number of firms are embracing environmental disclosure, and legislative efforts are steering towards mandating such disclosures, the comprehensive understanding of the environmental implications of these disclosures remains surprisingly limited. A significant gap exists in understanding the challenges of environmental disclosure in promoting sustainability and complex consequences in various contexts.

The dissertation aims to fill this literature gap by focusing on the …

“…She Complained…”: The Female Complaint And Voice In F. Scott Fitzgerald’S Works, Kristina Syrigos

Theses and Dissertations

My thesis explores the themes of female complaint and female voices in the works of F. Scott Fitzgerald, specifically focusing on "The Cut-Glass Bowl," "Winter Dreams," and The Great Gatsby. Drawing on J. L. Austin's concept of performative speech and Sarah Ahmed and Lauren Berlant’s explorations of the female complaint, I argue that Fitzgerald's female characters are silenced, dismissed, and punished when they express their wants, desires, and grievances. Despite their attempts to use their voices, words, and complaints to enact change in their lives, these women are portrayed as nagging and powerless, oftentimes being punished for speaking up, …

Examining The Effects Of Physical Education Teacher Behaviors On Actual Motor Competence And The Associations Among Actual Motor Competence, Perceived Motor Competence, Enjoyment In Physical Education, And Physical Activity In Early Childhood, Unjong Lee

Theses and Dissertations

Physical Education (PE) can be considered a black box when the interactions between the teacher and the students are unknown. PE as the black box has been embedded in the process-product paradigm. PE teachers can be critical role models for fostering students’ actual motor competence (AMC) because students can learn from what they observe from teachers’ behaviors. Additionally, AMC, perceived motor competence (PMC), and enjoyment in PE can be potential factors to increase students’ PA in schoolbased setting. Therefore, this dissertation consists of two studies that examine PE teacher behaviors, AMC, PMC, enjoyment in PE, and PA in early childhood …

The Effects Of Writing Groups On Student Self-Efficacy, Katie Francom

Theses and Dissertations

High school students often lack confidence in their writing. One way to change this is by increasing their self-efficacy regarding writing. Previous studies suggest that writing groups have effectively improved students' self-efficacy in higher education. However, more must be done to see if this same intervention would succeed in high school. This study aimed to test this hypothesis and answer the question: How does participating in writing groups shape adolescents' writing self-efficacy? To do this, 57 11th-grade students participated in writing groups in an Honors English 11 class over a semester. For the study, they were surveyed about their writerly …

Addressing A Crisis In Nursing Practice: Exploring The Impact Of Multimedia Case-Based Learning On The Clinical Judgment Of Undergraduate Nursing Students, Macy Jenette Bennett

Theses and Dissertations

Clinical judgment is a priority nursing skill to ensure the delivery of safe and effective nursing care. New graduate nurses and nursing students lack the clinical judgment skills that are necessary for entry-level nursing practice. Nurse educators must therefore implement teaching strategies that facilitate clinical judgment. This study evaluated the clinical judgment of undergraduate nursing students after the implementation of multimedia case studies related to the concept of perfusion. Two research questions guided this study: (a) in what ways do undergraduate nursing students demonstrate clinical judgment after completing a series of perfusion-related multimedia case studies and (b) to what extent …

Second-Grade Students’ Lived Experiences During Formal And Informal Music Learning Activities, Celina Liana Reed

Few researchers have examined elementary students’ lived experiences during formal and informal music activities. My education and 9 years of early childhood and elementary music teaching experiences contribute to my research qualifications. The purpose of this research was to examine my second-grade students’ lived experiences during formal and informal music learning activities. Following were the guiding research questions: (a) What do second-grade students think and how do they feel during formal music learning …

Black Mph Internship Experiences In Racialized Organizations: Critical Counter-Narratives For A More Racially Just Public Health Workforce, Zach Jenkins

Theses and Dissertations

Internships are a vital component of Master of Public Health (MPH) programs. Despite 14% of MPH students identifying as Black, limited research has examined their internship experiences. This is particularly troubling given the racial demographics of the public health workforce and the racialized nature of most public health organizations. Using critical race theory (CRT) as a theoretical framework and critical counter-narrative as a methodology, this study sought to answer the following research questions: 1) How do Black MPH students describe their racialized experiences in their internships? and 2) What are the implications of Black MPH students’ narratives for policies and …
