Thinking Like An Historian: Improving Engagement Through Project-Based Learning In A United States History Classroom, George Gray

Theses and Dissertations

The purpose of this action research study is to determine the efficacy of project-based learning activities for improving students’ critical thinking skills and engagement in the classroom. South Carolina’s creation of the United States History end-of-course assessment has led many social studies teachers to design ‘teach to the test’ lesson plans, which this researcher’s students seem to find mundane and uninspiring. Although these teaching methods have helped some students perform well on the end-of-course test, these tactics have sapped their interest in social studies and have not prepared them to be responsible citizens in an active democracy. The social studies …

Using Geospatial Tools To Assess Changes To Marine Ecosystems In Small Island Developing States Following Hurricane Disturbances: A Case Study Of Dominica After Hurricane Maria, Ryan J. Shields

Theses and Dissertations

Seagrass meadows, like coral reefs, are in decline globally but are often neglected in marine policy and conservation despite their equally critical ecosystem services. Both habitats can be heavily impacted by wave surges, rainfall-induced earth movement and flooding, changes to water temperature, salinity, and acidity, and increased levels of turbidity—all occurring at increased rates due to a changing global climate. We demonstrate that multispectral satellite imagery, geospatial tools, and classification techniques can be used to inform management by identifying and quantifying changes in seagrass distribution and the presence of sediment-related threats. Results from Dominica indicate near-shore seagrass habitat area increased …

Husserl And Merleau-Ponty: A Feminist Critique Of The Phenomenological Body, Jasmin M. Makhlouf

Theses and Dissertations

The purpose of this thesis is to explore the phenomenological notion of embodiment, to explain the objectification and coercion that women and their bodies experience on a daily basis. I build the philosophical foundation of this thesis on Husserlian and Merleau-Pontian phenomenology, as well as, their work’s receptions in feminist philosophy of the early 20th century, mainly Simone de Beauvoir, as well as, more contemporary thinkers like Luce Irigaray and Judith Butler. Moreover, the thesis argues for a return to the traditional phenomenological notion of embodiment while incorporating elements of sexuality and sexual difference.

Polymer Microparticles For Encapsulation And Presentation Of Anti-Inflammatory Agents For Inflammatory Diseases, Christopher Isely

Theses and Dissertations

Inflammatory diseases have a huge economic impact on the healthcare system. Incidence of obesity and muscle atrophy, two high profile inflammatory diseases, continues to increase. Anti-inflammatory agents are potential therapeutics for these diseases. Resveratrol is a polyphenol that has anti-inflammatory effects; however, resveratrol suffers from low bioavailability and hasn’t had impressive clinical results when delivered orally. Mannose is a monosaccharide that also has anti-inflammatory effects, however, effects are highest when mannose is presented on the surface of a support the size of a bacteria. Incorporation of resveratrol and mannose into biodegradable polymer microparticles could be a feasible approach to overcome …

Defining The Pathophysiology Of Gut Humoral Immunodeficiency, Ahmed Dawood Mohammed

Theses and Dissertations

Mucosal antibodies maintain gut homeostasis by promoting spatial segregation between host tissues and luminal microbes. Antibody-deficiency is the most common form of primary immunodeficiency observed in humans. In antibody-deficient humans, abnormal composition of the gut microbiota ('dysbiosis') is associated with chronic inflammatory responses and gastrointestinal complications. However, the mechanisms by which dysbiosis promotes inflammatory disease are poorly defined. In the studies described in this dissertation, we utilize CD19-/- mice as a model of antibody deficiency to test the hypothesis that antibody deficiency negatively impacts gut physiology under steady-state conditions. Chapter #1 is an overview of B cell development and how …

Spatial Orphans: Cultural Mobility And The Extranatural In Black American Literature, Kelsey Nichole Flint-Martin

Theses and Dissertations

In his 2005 book Conjure in African American Society, Jeffrey Anderson notes that America’s historical and academic interest in conjure has come in waves with each wave correlating to a different significant period in the fight for Black equality: Reconstruction, the Great Migration, and the Civil Rights Movement. In each of these movements, Black people have fought to find a way to belong in the United States as an equal, often undergoing travel and moving to different towns where they could have better economic, physical, or other freedoms. Since the start of the 21st century, there has been another revival …

Neurodevelopmental disorders in children including Autism Spectrum Disorders (ASD) and Intellectual disability (ID) are the topics of growing concern and recently many studies looked for the risk factors of these disorders. Although antidepressants and antiepileptics consumption during pregnancy have been reported to be associated with ASD, the effect of NSAID or acetaminophen, two most common drugs used during pregnancy, have been under researched. We conducted a prospective cohort study linking data from Medicaid, Department of Education, and Department of Disabilities and Special Needs with birth certificate data from mothers and children between 2010-2017. Beside exposure variables, NSAID and acetaminophen, and …

Molecular Basis Of Xenobiotic Metabolism And Resistance In Tetranychus Urticae, Leily Daneshian

Theses and Dissertations

Invasive pest species are a major cause of crop loss around the world and adversely affect the agricultural industry. We are focusing on Tetranychus urticae (two-spotted spider mite; TSSM), which is a polyphagous pest that targets more than 1100 plant species. The TSSM alone causes a loss of roughly $1.6 billion per year globally due to acaricide resistance. It is developing resistance to most acaricides due to rapid growth and reproduction. Therefore, new acaricides are needed to combat TSSM resistance and infestation [1]. To address this problem, four enzymes of TSSM, intradiol ring cleavage dioxygenases, a glutathione S-transferase, a β …

A Culture Of Control: Progressive Era Eugenics In South Carolina As A Continuation Of Created White Supremacy, Hannah Nicole Patton

Theses and Dissertations

This work examines the evolution of eugenic ideology in South Carolina during the Progressive Era by following relevant discussions published in The State newspaper. Between 1891 and 1939, The State newspaper provided a platform for discussions about eugenic ideology to be disseminated to the general public. Through eugenics the white portion of the South Carolina population saw a way to retain white supremacy and create better progeny. An examination of The State reveals a network of discussions that reached across South Carolina, the United States, as well as Western Europe. The existence of newspaper articles illustrates cultural integration in the …

Investigating The Dynamic Interactions Of Rapidly Growing Precocial Shorebird Chicks, Luke R. Wilde

Theses and Dissertations

Organisms in dynamic environments must continually reassess the cost-benefit trade-offs of their interactions and adjust their behaviors accordingly. Nevertheless, ecological research often takes a ‘snapshot’ approach to studying interactions across sample locations and timepoints. Investigating ecological interactions in this way can miss important information about the influence spatiotemporal context has on the scale and direction of their effects. Longitudinal studies that follow individuals can elucidate how changing contexts affect an individual’s ecology while deepening our understanding of adaptive behavior. However, determining how context influences the effect of an interaction requires it be measured across a range of spatiotemporal conditions. Studying …

Applications And Mechanisms Of Near Infrared Spectroscopy For Age Estimation In Otoliths Of Red Snapper Lutjanus Campechanus, Michelle S. Passerotti

Theses and Dissertations

Near infrared spectroscopy (NIRS) is a light spectroscopy method useful for non-invasively discriminating and quantifying chemical composition of a wide variety of substances. Recently-developed applications of NIRS to fish age estimation across a range of taxa have sparked intense interest in exploring the feasibility of its use for rapid age estimation in fisheries population management. In this pursuit, development of species-specific calibration models relating traditionally-derived age estimates (i.e., those estimated from growth band counts) to NIR spectral signatures from ageing structures is required to derive predictive models that can then estimate age from rapid scans of whole ageing structures alone. …

Removal Of Selected Organic Contaminants By Various (Nano) Adsorbent-Ultrafiltration Hybrid Systems, Sewoon Kim

Theses and Dissertations

Organic contaminants, which result from overuse and discharge of dyes, pharmaceutically active compounds, personal care products, and endocrine-disrupting compounds, have been received attention as contemporary water issues. However, conventional water and/or wastewater treatment system cannot sufficiently control for these contaminants for their stability and complexity. In this study, combined novel adsorbent with ultrafiltration (UF) hybrid system (termed ‘adsorbent-UF’) was applied to removal selected organic contaminants. UF with upstream adsorption has positive effects on performance in terms of the removal of selected organic contaminants, separating used adsorbents and reducing foulants. Activated biochar, metal organic frameworks, and Ti3C2TX MXene were used as …

Dreadds Modulation Of Operant Behavior In Male And Female Hiv-1 Transgenic And F344/N Rats, Jessica Illenberger

Theses and Dissertations

The neurobiological processes which determine the choice between 2 (or more) reinforcers are unidentified despite the remarkable benefits which could result from better understanding or control of such processes. Most prominently, reducing choices to pursue drug over non-drug reinforcers could curtail the development or continuation of drug dependence. Likewise, increasing goal-directed behavior in single-schedule and choice settings may alleviate some of the consequences of apathy, a reduction in goal-directed behavior which can occur with neuropathologies including HIV-associated neurocognitive disorders. Dysregulation of the mesolimbic circuit, connecting the ventral tegmental area to the nucleus accumbens, has been implicated in both drug dependence …

Buffering Effects Of Support Resources On Perceived Stress And Socioeconomic Status In Predicting Longitudinal Physical Activity Among African American Women, Asia Mae Brown

Theses and Dissertations

Physical activity (PA) plays an integral role in reducing risk for the leading causes of death, including cardiovascular disease, stroke, cancers, and type two diabetes. Lower rates of physical activity (PA) among African American women continue to perpetuate health inequities. Both perceived stress and low socioeconomic status (SES) negatively impact PA, but the presence of support resources may moderate these effects. Secondary data analyses of female African American caregivers (n = 143) were conducted using data from the Families Improving Together (FIT) for Weight Loss trial (R01DK067615; PI Wilson DK) to examine the moderating effects of supports (self-efficacy, perceived social …

A Study Of Prosocial Behavior, Workplace Civility, And Work Engagement Among Employees In Higher Education, Shelley Haddock Dempsey

Theses and Dissertations

This quantitative research study examined the relationship between prosocial behavior, work engagement, and workplace civility among higher education professionals. The specific university employees it studied were student affairs staff, academic affairs administrators, and faculty. Responses to a survey by a national random sample allowed the researcher to determine the relationship between a respondent’s prosocial nature and both their workplace civility and their work engagement. In the end, all three hypotheses were supported by the data: (a) prosocial behavior scores of student affairs staff and academic affairs administrators are higher than those of faculty, (b) the prosocial behavior scores were positively …

Early Premature Infant Physiologic And Behavioral Indicators Of Ans Instability, Karen Popp Becker

Theses and Dissertations

The advanced survival of the early premature infant (EPI) since the post-surfactant era has not improved many comorbidities. EPI comorbidities influence their lifelong health, social, and cognitive outcomes. EPIs often have immature and disorganized responses to stimuli during the neonatal period. EPIs respond to stressors from the Neonatal Intensive Care Unit’s (NICU) environment, stimulation, or disease states based on physiologic system changes, often resulting in observable behavioral changes. Both physiologic and behavioral changes reflect autonomic nervous system (ANS) disruption, thus instability. Instability of the ANS due to chronic stressors, can lead to chronic physiologic dysregulation and lead to lifelong health …

“Everything Will Be As It Is Now, Just A Little Different”: Affectively Imagining Alternative Worlds In Ben Lerner’S 10:04, Grace Riley

Theses and Dissertations

One of the most crucial concerns of cultural criticism today is the question of how to grapple with what Mark Fisher refers to as the “malaise” of the present; the pervasive belief that capitalism is the only viable option, that there is no alternative ‘other.’ However, there remains a vibrant scholarship committed to resisting such pessimism that theorizes the possibility of alternative, utopian futures that lie athwart the apocalyptic present. This thesis explores the question of how one begins to imagine such alternative futures from within a capitalist order that constantly works to pre-emptively subsume any possibilities of resistance. Art …

Zooplankton Community Structure And Grazing Within A Stormwater Detention Pond In Coastal South Carolina, Kristen Laccetti

Theses and Dissertations

Stormwater detention ponds (SDPs) on the coast of South Carolina have become increasingly prevalent as the area experiences rapid urbanization. SDPs are man-made reservoirs implemented to minimize pollution inputs into receiving waters and are home to diverse biota, including zooplankton. Zooplankton are a good water quality indicator due to their quick response times and trophic regulators of phytoplankton through grazing. Zooplankton and phytoplankton interactions in stormwater detention ponds are an essential component for understanding plankton community dynamics in SDPs. This purpose of this study was to determine the seasonal variability in zooplankton community composition and grazing rates at 14-day intervals …
