The Mountains Call: Escaping To Zones Of Seclusion, Alec Lee Parry

Theses and Dissertations

The biographical and thematical overlap between the literature of Austrian authors Ingeborg Bachmann and Thomas Bernhard, and Swiss writers Max Frisch and Fleur Jaeggy, is established in literary scholarship. However, similarities in the role Alpine spaces play in their works remain unaccounted for. The Alps represent a cultural and geographical boundary between linguistic identities and international borders. Protagonists across this dissertation’s three chapters face internal crises, prompting them to move to “zones of seclusion.” Within these “zones of seclusion,” characters spark discussions of collective memory even if they are isolated themselves. These peripheral locations force recollection, often on collective memory, …

Between What’S Promised And What’S Lived: Lgbtq Former College Athletes’ Experiences At Inclusive Institutions, Alyssa Morgan Edlin

Theses and Dissertations

Despite the increased visibility of lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) inclusion in college sports, it remains unclear whether athletes find these environments truly safe, supportive, and able to live authentically. Institutional evaluations and rankings often focus on policies and public commitments, offering limited insight into how inclusion is experienced in everyday athletic settings. Consequently, little is known about whether institutions labeled as inclusive actually foster environments where LGBTQ athletes feel a sense of belonging, authenticity, and meaningful support.

Rooted in an interpretivist-constructivist paradigm and guided by narrative inquiry (Clandinin & Connelly, 2000), this study examines the …

Evidence Of Metal-Microcystin Complexation And Its Potential Role In Environmental Fate, Ashley Marie Womer

Theses and Dissertations

Microcystins that enter freshwater systems pose a threat to human health therefore their fate and transport throughout the water column have been intensively studied. While sediment has been regarded as an environmental fate for microcystin (MC), less is known about the molecular mechanisms by which microcystin interacts with the sediment and/or the thermodynamic stability of these interactions. While microcystin has a half-life in lake water on the order of weeks, microcystin adsorbed to sediment can be detected hundreds of years later1-2. Microcystin has been desorbed from these sediments with various EDTA solutions, therefore, work is presented to support the hypothesis …

Surface Salinity Variability And Loop Current Frontal Eddy Activity In The Gulf Of Mexico, Pamela Jo Lee

Theses and Dissertations

The Gulf of Mexico (GoM) is a dynamic semi-enclosed basin where mesoscale and submesoscale circulation regulate the distribution of freshwater, nutrients, and biological productivity. The Loop Current System (LCS), which includes the Loop Current (LC), Loop Current Eddies (LCEs), and Loop Current Frontal Eddies (LCFEs), exerts the dominant control on basin-wide circulation. These features interact with freshwater input from the Mississippi-Atchafalaya River System (MARS) and with saline inflow from the Caribbean, resulting in variability in sea surface salinity (SSS) and chlorophyll-a (Chl-a) across a range of spatial and temporal scales. A primary focus of this work is understanding how the …

A Combined Observational And Reanalysis Approach To Beaufort Gyre Freshening, Christina Mccarty Gregory

Theses and Dissertations

The freshwater (FW) content in the Arctic plays a critical role in the global climate by influencing the regional physical and biological processes, large-scale ocean circulation in the North Atlantic, sea-ice albedo, and other crucial climate parameters. Located in the Canadian Basin, the Beaufort Gyre (BG) is the largest retainer of FW in the Arctic. Here we examine the dynamics of the BG between 2016-2018 using satellite-derived products and ocean reanalysis parameters. Our results demonstrate that the characteristics of BG during the years of this study are a complex combination of various processes. The Ekman-induced FW fluxes were separated into …

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 …

Theses and Dissertations

Despite extensive intervention efforts, breast cancer remains the most common cancer among women in the United States and the second leading cause of cancer-related deaths in women. Prior research in breast cancer communication has largely focused on older women, yet early-onset breast cancer among younger women (ages 18-39) has increased in recent years. This trend highlights an urgent need for tailored communication strategies to improve young women’s understanding of breast cancer risk factors, prevention, detection, treatment, and survivorship. The present study developed and tested a digital narrative game based on the Health Belief Model, as a potential tool to enhance …

A Study Of Type Ia Supernova Spectra, David Edwins

Theses and Dissertations

Type Ia Supernova already represent a valuable tool for astronomical exploration by providing a bright standardizable candle, however, they also represent an opportunity to observe the matter in the universe along the line of sight. A study of the spectra of Type Ia supernovae reveals a variety of contamination of these spectra at a variety of locations, including the Milky Way galaxy, a source likely local to the original supernova and an as yet unidentified source of contamination. Further, Type Ia Supernova appear to change with the redshift of the supernova.

Continuous Imaging Of The Shallow Subsurface Of Horry County Using Gpr And Auger Data, Chase William Robinson

Theses and Dissertations

Welded barrier systems are common along passive margins globally and make up approximately 15% of the coastlines around the world. The subsurface facies assemblages of welded barrier systems record depositional histories and past sea-level dynamics, but their complicated depositional architecture can be problematic for understanding aspects like groundwater flow and freshwater-saltwater exchange. Most studies of modern welded barrier sedimentary systems using ground penetrating radar (GPR) rely on a few 100 meters of subsurface data supplemented with a few drill cores. In this study, we used over 75 km of 100MHz and 25MHz GPR data and 195 auger drill logs collected …

Theses and Dissertations

An examination of the communicative strategies of B2-level English language learners was conducted to investigate the evolutionary trajectory of strategic deployment in informal, collaborative, and non-instructional settings. While traditional research has predominantly focused on digital or explicitly educational games within controlled, single-session tasks, a notable gap remains in understanding how learners navigate the linguistic and social demands of non-pedagogical, commercially available board games over repeated encounters. This qualitative case study addressed this gap by observing four learners as they engaged in four sessions of Forbidden Desert, a collaborative survival board game.

The theoretical framework integrated Sociocultural Theory, Communicative Competence, and …

The Role Of Parenting Factors On Moderating The Effects Of Parent Perceived Stress On Waist Circumference And Family Mealtime Outcomes In Black Adolescents With Overweight And Obesity, Taylor Ryan White

Theses and Dissertations

Family mealtime is a protective factor for adolescent health outcomes (e.g. well-being, diet quality); however, parent stress may diminish the frequency and quality of family meals and increase obesity risk through physiological (e.g., allostatic load) and behavioral (e.g., decreased physical activity (PA), obesogenic diet) pathways. Parenting factors, like responsive parenting (e.g., providing support for adolescent healthy eating) and feeding practices (e.g., parental monitoring - tracking adolescent diet), may mitigate the effects of parent stress by promoting adolescent behaviors (e.g., nutritious eating, increased PA) that are linked with healthier weight outcomes; however, few studies have examined this in Black families. Therefore, …

An Agile-Informed Job Demands-Resources Framework In Hospitality: A Dual-Pathway Structural Model Of Employee Satisfaction, Burnout, And Turnover Intentions, Albaraa Mesawi

Theses and Dissertations

Persistent labor shortages and elevated voluntary turnover define the hospitality industry. High-intensity service interactions increase workload, emotional labor, and time pressure for non-management employees. The Job Demands-Resources (JD-R) model predicts engagement and retention when job resources offset job demands. Existing research has not specified which operational conditions reliably predict this balance in dynamic service work. This study evaluates whether adapted Agile philosophy serves as a heuristic framework for specifying JD-R constructs in hospitality. The study maps Agile values and principles to validated psychological constructs through Psychological State Matching: Self-Organization to Psychological Empowerment (PE), Regular Reflection to Perceived Team Learning Behavior …

(Un)Celebrated Women: Three Women Authors And Their Imprint On The Gullah Geechee Literary Tradition, Raven Mariah Gadsden

Theses and Dissertations

Three women authors, Laura Middleton, Julia Peterkin, and Zora Neale Hurston, are responsible for the creation of some of the most important Gullah Geechee literary images in the 1920s and 1930s. By examining the historical moments and movements which were active while these women were writing, it is obvious why these women are at the center of this conversation. Each of these women’s writing plants the seed for a Renaissance of Gullah Geechee representation. While Middleton's work never gets published, her documentation of black life in South Carolina for the Federal Writers' Project worked as a counter narrative to texts …

Effects Of Face-To-Face Communication On Network Recall, Gage Austin Pierce

Theses and Dissertations

Research in the field of social cognition found that humans use schema for the storage and processing of network information. Schema use differs by gender and power, in theory because individuals differ in the schemas that apply to the network structures they are involved with. I analyzed a survey dataset collected during the COVID-19 pandemic that asked respondents about how often they interacted with people, and organizations, as well as what forms of communication they used. In addition, a network recall survey experiment was conducted to measure their network recall accuracy. If schema are learned cognitive rules the brain uses …
