Theses

Communicating large datasets in ways that are appealing to non-scientific audiences has been a recent focus of big data visualization. Interest has grown for using 3D environments with game-like structures and immersive technology like AR and VR since they are more engaging. We introduce a method, based on the structure of the datasets and domain knowledge of the natural phenomena, for transforming public National Aeronautics and Space Administration (NASA) Earth datasets into 3D narrative data visualizations, specifically of disaster events. Two visualizations were created using this method: one of the KNP Complex Wildfire in 2021 and one of Hurricane Beryl …

Optical Turbulence Estimation From Numerical Weather Prediction Models: Methods And Error Analysis, Richard Minor

Theses

Optical turbulence plays a critical role in electromagnetic wave propagation through the atmosphere, directly affecting imaging systems, wireless communications, and high-energy laser (HEL) performance. Realistic three-dimensional characterization of atmospheric turbulence is essential for understanding these impacts, particularly within the atmospheric surface layer, where turbulence is often strongest. The refractive index structure parameter, Cn2, is used to quantify optical turbulence. This thesis evaluates the capability of the High Resolution Rapid Refresh (HRRR) model to characterize surface layer Cn2. As the highest resolution and most frequently updated numerical weather prediction model covering the continental US, HRRR offers strong potential for operational HEL …

Intercomparison Of Remote Sensing Methods For Calculating Cn² Profiles, Isaiah Joseph Montgomery

Theses

Propagation of electromagnetic waves through the atmosphere is affected by turbulence. The impact of turbulence on wave propagation is characterized by the refractive index structure function (Cn²), which characterizes the intensity of fluctuations of the refractive index of air due to turbulence. Observations of vertical profiles of Cn² are essential for evaluating numerical model predictions. This study presents an intercomparison of Cn² derived from multiple ground-based remote sensing systems, including 915 MHz profiler, sodar, and a parameterized method that uses doppler wind lidar and radiometer. Results indicate that the sodar is the most accurate near- surface Cn² profiler, but above …

Mapping Cave Vulnerability And Priority Areas For Biospeleological Conservation, C. Lael Anderson

Theses

Alabama contains some of the highest levels of subterranean biodiversity in North America, yet no statewide assessment of cave vulnerability has previously been conducted. A spatially explicit vulnerability assessment was developed for Alabama caves using species occurrence records, landscape characteristics, anthropogenic threat data, and groundwater vulnerability metrics. Distribution maps were generated for cave- obligate and bat species, and vulnerability was assessed using human population, land- use, groundwater quality, groundwater quantity, and modified DRASTIK models. Results identified numerous single-site endemic species, regional biodiversity hotspots, and cave systems facing elevated anthropogenic threats. Conservation priority rankings highlighted species and caves of greatest management …

Developing And Evaluating A Multidimensional Measure Of Pride In The Lgbtqia+ Community, Donovan Edward

College of Graduate Studies: Theses & Dissertations

Pride in LGBTQIA+ spaces has thus far been an ethereal concept with no universally agreed-upon definition. Previous literature frequently connects pride to traits such as resilience, comfort, confidence, and identity expression. This is a critical oversight, as most measures of LGBTQIA+ experiences focus on the negative aspects of queer experiences (e.g., vulnerability, victimization) or are created to evaluate non-LGBTQIA+ perceptions of LGBTQIA+ people, falsely characterizing this community in a deficit-based light. In response, this study aimed to offer a holistic definition of pride and develop a psychometrically sound measure of pride stemming from culturally salient expressions by using rigorous analytical …

How Does Language Influence Interest In Psychological Treatment?, Alexis B. Dixon

College of Graduate Studies: Theses & Dissertations

In 2022, approximately 59 million adults in the United States were diagnosed with a mental health disorder, and approximately half received mental health services (NIMH, 2023). Given the number of individuals whose mental health concerns remain untreated, it is vital to investigate mechanisms predicting treatment-seeking behaviors. Health literacy, which influences treatment-seeking, is largely absent from research on barriers to mental health treatment. Health literacy is related to readability, the ease of reading (Adkins & Singh, 2001), and jargon, the technical language used by professionals in a field (Shulman et al., 2020). Health materials are often written at a high reading …

Math Toxicity: A Psychoanalytic Examination Of Blips And Belonging In Mathematics Education, Kimberly R. Kirstein

College of Graduate Studies: Theses & Dissertations

This dissertation examines how secondary mathematics education functions not only as a curricular and institutional structure but as a lived, relational, and affective experience for students. While mathematics education research has extensively documented patterns of achievement, access, and anxiety, far less attention has been given to how students come to experience mathematics as a site of threat, shame, and diminished worth. This study introduces the concept of math toxicity to describe the cumulative harm produced when mathematics operates as a gatekeeping mechanism that links performance to identity and value. Drawing on historical analysis, psychoanalytic theory, and autobiographical inquiry, this research …

Experiencing Followership: A Hermeneutic Phenomenological Study Of Executive Assistants In Higher Education, Trina R. Smith

College of Graduate Studies: Theses & Dissertations

The burgeoning study of followership needs more follower-centric qualitative research that describes follower beliefs, attitudes, perceptions, and experiences. The traditional view of leadership is that a single person is responsible for the success or failure of a project, team, or organization. However, scholars have suggested that 80% of the success of a team or organization may be attributed to followership. Followership research is rapidly expanding, and scholars are calling for more empirical follower-centric research to add to the discipline. Likewise, the executive assistant (EA) position is one of increasing responsibility, but there are few empirical studies on EAs' experiences across …

The Influence Of First-Year Seminar Course Modality On The Academic Outcomes Of First-Generation College Students, Keia Dodd

College of Graduate Studies: Theses & Dissertations

When universities effectively implement first-year seminars, a popular type of support designed to assist students during their initial year of college, they can meaningfully boost the academic performance of first-generation college students. This study examined whether first-year seminars influenced the academic outcomes of first-generation college students at a specific institution compared with those of their continuing-generation peers. Specifically, it investigated the extent to which course modality (face-to-face, online, or hybrid) influenced variation in first-semester grade point average (GPA) and first-to-second-year retention after controlling for race, sex, and first-generation status. The sample included 7,848 first-time undergraduate students. Multiple linear regression was …

Comparison Of 2000-Meter Row Prediction To Measured Vo2peak During Gxt, Andrew S. Ashley

College of Graduate Studies: Theses & Dissertations

BACKGROUND: Aerobic capacity is essential for the performance of military personnel and first responders. Traditionally, graded exercise tests (GXTs) with metabolic gas analysis have been the criterion-referenced method for assessing aerobic fitness. However, treadmill running and cycle ergometers may not fully reflect the whole-body demands required in tactical environments. Rowing-based assessments and the currently commercially available VO2max prediction formula are widely used across tactical organizations as practical field measures, and most tactical operators are considered inexperienced rowers, which has been minimally examined. PURPOSE: The purpose of this study is to compare measured VO2peak from a rowing GXT with estimated VO2max …

Assessing The Diversity And Composition Of Crayfish Assemblages In The Ogeechee River Basin, Reginald Turner

College of Graduate Studies: Theses & Dissertations

Crayfish assemblage composition in the southeastern United States is understudied relative to other aquatic taxa, such as aquatic insects and fishes, and the Coastal Plain watersheds of that region are particularly underrepresented in the contemporary literature on this topic. For example, although 38% of the crayfish species in Georgia are considered “species of greatest conservation need,” most of the distributional data used to make these designations are outdated, with some dating back over 50 years. This thesis sought to update our understanding of the contemporary distributions of crayfish species within the Ogeechee River Basin (ORB), a watershed in southeastern Georgia …

The Effect Of Complexity Of Expert Testimony And The Presence Of A Defensive Rebuttal On Jurors' Decisions In Criminal Trials, Shelby E. Madden

College of Graduate Studies: Theses & Dissertations

Forensic science plays a critical role in criminal trials, yet forensic techniques vary in their reliability. Expert testimony, often held in high regard by jurors, can be a decisive factor in verdicts, but its influence is complicated by factors such as technical complexity, adversarial bias, and heuristic processing. The present study examined how the complexity of prosecution expert testimony and the presence of a defensive rebuttal influenced jurors’ decisions when presented with faulty forensic evidence. Participants (N = 142) were randomly assigned to one of four conditions in a 2 (testimony complexity: high v. low) x 2 (defensive rebuttal …

Examining Firefighter Perceptions Of Stress And Recovery Across A Shift And Engagement In Recovery Activities, Nathan T. Ebersole

College of Graduate Studies: Theses & Dissertations

The occupational demands of firefighting, such as fire suppression and rescue tasks, working in hazardous conditions, inconsistent sleep patterns, and exposure to traumatic events, can lead to work-related injuries, burnout, and feelings of isolation. To date, there is limited research on the impact of a single work-shift on firefighter perceptions of stress and recovery and the recovery activities that may influence these perceptions. Thus, the purpose of this study was to examine the effect of a single work-shift on firefighter perceptions of stress and recovery status as well as the recovery activities firefighters choose to engage in.

Emotion Regulation: The Effectiveness Of Reappraisal And Potential Benefit Of Music, Ezra J. Greidinger

College of Graduate Studies: Theses & Dissertations

Literature has supported potential benefits to cognitive reappraisal as a method of emotion regulation, as well as intentional music usage as an enhancer of these effects. It has been suggested that instruction be provided to individuals to use these methods, especially in highly stressed populations (Sakka et al., 2018). However, there has not been an experimental study to follow up on these claims. When instruction is provided, is cognitive reappraisal more effective than naturally developed habits in regulating anxiety, and would music enhance these effects? College students (N = 170) were randomly assigned to three treatment conditions: control, cognitive reappraisal, …
