Using a qualitative research design, six educators were interviewed …

Investigation Into Mycorrhizae Associated With Native Venus' Flytrap Root Tissue, Anna Carnaggio

Electronic Theses and Dissertations

Dionaea muscipula, a plant commonly known as the Venus' flytrap, is found native to the southeast corner of North Carolina and the northeast corner of South Carolina. Several populations of native Venus' flytraps are known to exist in the nutrient-poor peat bog conditions in and around Lewis Ocean Bay Heritage Preserve (LOBHP) in Northeastern South Carolina. Anthropogenic pressures in Horry County, specifically surrounding LOBHP, have resulted in a loss of habitat for several native and endangered species. As a result, conservation efforts are focused on relocating native Venus' flytraps into adjacent habitats to ensure survival. This is only a temporary …

Making Tabby, Making Place: Examining A Gullah Geechee Wattle And Tabby Daub Dwelling Through Thin Section Analysis, Jacob E. Hamill

Graduate Masters Theses

Tabby is a building material made from lime, sand, oyster shell, and water that is geographically associated with the Sea Islands of South Carolina, Georgia, and Florida. This material was used from the early 18^th century to end of the American Civil War to construct all-manner of buildings in the Sea Islands region. Enslaved African descendant communities constructed wattle and tabby daub dwellings within plantation landscapes, and these settlements are interpreted as spaces where enslaved people exercised greater spatial autonomy.

This thesis analyzes the remains of a wattle and tabby daub structure located on what was once Old Fort …

Sexual And/Or Gender Minority (Sgm) Stigma Within Nursing Schools: The Relationship Between Stigmatic School Attributes, Minority Stressors, And Sgm Nursing Student Mental Health, Michelle Gee

Dissertations

Nursing education is heteronormative and cis-normative, which has been correlated to stigma and ignorance exhibited by nurses towards sexual and/or gender minorities (SGM). Minority Stress Theory (MST) states that circumstances in the environment that promote stigma related to minority identities lead to unique minority stressors, such as discrimination. These minority stressors subsequently affect mental health. While it is known that SGM patients experience mental health issues that relate to stigma and discrimination in healthcare settings, nothing is known about SGM nursing students dealing with stigma and discrimination within nursing education. The aim of this descriptive correlational study was to inform …

Unschoolers In Higher Education: A Narrative Case Study Of Unschoolers’ Sense Of Belonging At University, Melissa Marie Carlson

Dissertations

Approximately 20% of families engaged in homeschooling have selected unschooling as their educational approach, with estimates suggesting this number may be even higher (Vesneski et al., 2022). Unschooling emphasizes the establishment of an environment where children can autonomously direct their learning by exploring their interests, unencumbered by traditional educational milestones or specific schedules (Arnall, 2018; Riley, 2020; Riley & Gray, 2015). Despite increasing public acceptance and recognition, research on the outcomes for unschoolers—particularly those pursuing higher education—is limited (Riley, 2020).

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Drought and insect herbivory are two major stressors on high-value crops like soybean (Glycine max). However, few studies have explored how these stressors interact, despite their presence in tandem under field conditions. We investigated how drought stress and fall armyworm (Spodoptera frugiperda) caterpillar herbivory impact Magellan (drought-tolerant) and Blackhawk (drought-susceptible) soybean cultivars. The soybean plants were subject to four treatment groups (1. Drought 2. Herbivory 3. Drought + Herbivory 4. Well-Watered) during a treatment period of 7 days in a greenhouse. We then measured plant height, physiological traits, trichome density, soil moisture, and larval mass gain. …

Understanding Factors That Drive Wildlife Mortality During Prescribed Fire Management Of Prairie Restorations, Hunter M. Griffey

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Fire is a key ecological disturbance, which plays a vital role in maintaining biodiversity and early successional species. For today’s land managers, prescribed fire is key in the restoration and maintenance of prairie ecosystems, halting woody encroachment and creating habitat desperately needed by many species. However, fire may have unintended effects on wildlife populations through direct mortality. Among taxa living in fire-dependent ecosystems, reptiles are predisposed to direct mortality, and several studies have recorded significant mortality during prescribed burns. However, the few studies investigating reptile mortality in prescribed fire are limited by small sample sizes and generally have limited analysis …

Controls On Nutrient And Sediment Export In A Non-Perennial Agricultural Stream, Kathleen Cutting

Graduate Theses and Dissertations

Climate change is expected to increase flow variability and intermittency in streams, changing the magnitude and timing nutrient and sediment delivery. This may exacerbate water quality issues in agricultural landscapes, where nutrient and sediment inputs are often elevated. Elevated nutrients can drive eutrophication in downstream waterways, and excess sediment loss can decrease primary productivity. Non-perennial headwater streams are particularly vulnerable to the impacts of climate change and agriculture as they serve as key sites for nutrient cycling at the terrestrial-aquatic interface. Despite their importance, the interactive effects of agriculture and stream intermittency, as well as unpaved roads in rural watersheds …

Silver Nanoparticles In Ammonia Sensing And Photovoltaics, Madhuka Liyanage

All Dissertations

Nanocomposite films (NCF) containing silver nanoparticles (AgNPs), separated by thin layers of silica/poly-4-vinylpyridine/polyvinylpyrrolidone, were fabricated via drop casting, spin coating, dip coating on glass substrate and drop casting on nylon filter membranes. The more uniform films were produced by drop casting on nylon filter membranes due to their solvent wicking properties. The films demonstrate electrical conductivity that varies in response to moist ammonia and water vapors. The changes in conductivity are attributed to hydrogen bonding between ammonia and water molecules with the silica/polymer layers, as well as the direct adsorption of ammonia onto the silver surface. Notably, NCFs with polyvinylpyrrolidone …

Development Of Rolipram Loaded Pgp Nanoparticles For Spinal Cord Injury Repair, Zhen Liao

All Dissertations

Spinal cord injury (SCI) leads to devastating neurological deficits due to primary mechanical damage and secondary injury mechanisms, including inflammation, oxidative stress, excitotoxicity, and inhibitory scarring, which collectively impede neural regeneration. One key aspect of SCI pathology is a significant reduction in cyclic adenosine monophosphate (cAMP) levels, primarily due to increased phosphodiesterase (PDE 4) activity. As a ubiquitous second messenger, cAMP regulates key signaling pathways, including protein kinase A (PKA) / cAMP response element-binding protein (CREB) and exchange protein activated by cAMP 2 (EPAC2). Therefore, restoring/increasing cAMP level is one of the major therapeutic strategies to reduce neurotrauma and restore …

Rhetorics Of Vigilance: Refracting Discourses In Technologies Of Self-Managed Health & Wellness, Haley Swartz

All Dissertations

Rhetorics of Vigilance explores the limits of feminist health rhetorics by examining technologies that promote women’s self-managed health and wellness practices. By establishing a corpus of personal health technologies and associated texts including mobile health applications, pelvic floor training devices, and perimenopause information shared on social media, this dissertation analyzes how discourses refract––redirected and often distorted––to implicate women in persistent self-monitoring. Drawing from interdisciplinary scholarship on women’s health from feminist rhetorical studies, rhetorics of health and medicine, science and technology studies, and digital studies, I theorize rhetorics of vigilance as a framework through which women understand and interpret issues …

Development Of Translational Microscale Systems To Interrogate How Biophysical And Biochemical Cues Alter The Phenotype Of Hormone Positive Breast Cancer, Braulio Ortega Quesada

Development Of Small-Molecule Inhibitors For Bacteroides, Naegleria, And Toxoplasma Microorganisms And Synthesis Of N-Heterocycles From Thiolated Ene-Ynes And Azodicarboxylates, Samuel Kwain

All Dissertations

Humans and microorganisms are intricately interconnected, with microbes constituting an essential component of human biology and ecology. This interdependence necessitates a delicate balance between leveraging beneficial microbes and mitigating the impact of harmful ones. The human gut microbiome, home to trillions of microorganisms, predominantly comprises commensal species that support health. However, dysbiosis within this ecosystem has been linked to serious diseases. For instance, an overrepresentation of Bacteroides species is associated with Type I diabetes mellitus (T1D) and various chronic gut disorders, including ulcerative colitis, inflammatory bowel disease, celiac disease, and colorectal cancer. Similarly, Naegleria fowleri, a free-living amoeba, causes …

Exploring Community Change Of North American Stream Fish Communities Due To Species Introductions, William K. Annis Jr

All Dissertations

The introduction of nonnative species has facilitated global changes in beta diversity, and these changes have been coined biotic homogenization (loss in beta diversity) and differentiation (gain in beta diversity). Homogenization represents a key conservation threat. Therefore it is imperative to understand the processes that allow nonnative species to establish and how these species contribute to beta diversity change. In this dissertation, I assess three key challenges exist in our ability to address these goals. One challenge is that we have inconsistent support among hypotheses of invasion drivers due to context dependency. Context dependency can arise due to differences in …
