Acquiring an additional language, especially whose linguistic systems differ from a learner’s first language, such as English and Japanese, is quite challenging. However, the improvement of technology such as Artificial Intelligence (AI) has some potential in supporting language learning.

This study investigated how ChatGPT can assist learners of Japanese whose first language is English in writing Japanese narrative of a 4-panel story and what learners notice comparing their Japanese writing with ChatGPT’s production. This study followed three steps: writing, an online survey, and a one-on-one interview. Four undergraduate students who were taking either a 200-, 300- or 400-level Japanese course …


Three Implications For Leibniz’S Principle Of Sufficient Reason, Josiah Omiecinski May 2026

Three Implications For Leibniz’S Principle Of Sufficient Reason, Josiah Omiecinski

Electronic Theses and Dissertations

The Principle of Sufficient Reason (PSR) states that for everything that is the case, there is a reason for it being the case. The PSR has been a widely used principle in philosophy dating back to Parmenides (~500 BCE). While many philosophers are commonly associated with the PSR, none are as strongly associated with it than Gottfried Wilhelm Leibniz. This paper derives three surprising implications for Leibniz’s PSR from Leibniz’s claim that God, an unlimited mind, does not engage in reasoning while limited minds, like humans, do engage in reasoning. The implications are: A distinction between the PSR qua a …


Hereditary Transmission Of Drumming Among The Anlo-Ewe: The Case Of Agbodo/Amuzu Family Of Hatsukorfe, Denu, Volta Region, Ghana, Ernest Elikplim Kwabla Adonoo May 2026

Hereditary Transmission Of Drumming Among The Anlo-Ewe: The Case Of Agbodo/Amuzu Family Of Hatsukorfe, Denu, Volta Region, Ghana, Ernest Elikplim Kwabla Adonoo

Electronic Theses and Dissertations

This study examines the hereditary transmission of drumming among the Anlo-Ewe of southeastern Ghana, focusing on the Agbodo/Amuzu family of Hatsuk?ƒe in the Volta Region. Situated within ethnomusicological discourse on traditional Anlo-Ewe musical practices and the specialized roles of the researched family, who are drummers of the exclusive Ye?e religious tradition, this research argues that drumming in this context is not merely a musical activity but a complex system of communication, identity, ritual authority, and cultural continuity. The study fills and addresses a significant gap in existing scholarship on the Anlo-Ewe music, which has largely emphasized community dance-drumming and institutional …

Recipe For Resistance: Oral Histories Of Queer Foodways In The Us South, Astrid Janie Knox-Mcconnell May 2026

Recipe For Resistance: Oral Histories Of Queer Foodways In The Us South, Astrid Janie Knox-Mcconnell

Electronic Theses and Dissertations

This thesis examines the emerging question of what constitutes “queer food.” It asks how this concept takes on a distinct regional form in the United States South. Drawing on oral histories, archival materials, and cookbooks, it argues that queer southern foodways are not only a subset of queer food studies, but also a distinct cultural and political formation shaped by southern histories of race, labor, family, and survival. The thesis makes the case that queer southern foodways function simultaneously as protest, utopian practice, and aesthetic pleasure. Through the act of cooking, eating, and sharing food, queer southerners articulate alternative social …


The Application Of Natural Language Processing Towards Auditing Of Unstructured Data: A Design Science Approach, Dennis K. Amoatey May 2026

The Application Of Natural Language Processing Towards Auditing Of Unstructured Data: A Design Science Approach, Dennis K. Amoatey

Electronic Theses and Dissertations

Financial auditors must manually review large volumes of unstructured text that may include contracts, internal policies, footnotes, and journal entry descriptions. This time-intensive process introduces risk of human error and inconsistency. Despite advances in automation, no systematic approach exists for applying Natural Language Processing (NLP) to this problem at scale. Using a design science approach, this study develops a framework that demonstrates how NLP techniques can be incorporated across key phases in the audit process, including planning, internal controls evaluation, evidence gathering, and reporting. Initial evaluation through expert feedback had a mix of responses. While some argued difficulty with data …

Stochastic Universal Differential Equations For Epidemiological Modeling: Uncertainty Quantification In Disease Transmission Dynamics, Alice Menaya Armah-Bonney May 2026

Stochastic Universal Differential Equations For Epidemiological Modeling: Uncertainty Quantification In Disease Transmission Dynamics, Alice Menaya Armah-Bonney

Electronic Theses and Dissertations

Epidemic forecasting requires not only predictions of expected case counts, but also quantification of uncertainty, although existing surrogate modeling frameworks for agent-based models remain fundamentally deterministic. In this thesis a Stochastic Universal Differential Equation framework is presented that extends the deterministic Universal Differential Equation approach by incorporating a learnable stochastic diffusion term, enabling calibrated probabilistic forecasts while preserving the mechanistic interpretability and computational efficiency of the deterministic baseline. In doing so, a two-phase training algorithm is introduced to ensure stable convergence and the framework is validated against the ensemble output from ExaEpi, an exascale agent-based model of a COVID-19 outbreak …


Attendance Matters: Incentive Programs And Chronic Absenteeism In Elementary Schools, Aubryn Street May 2026

Attendance Matters: Incentive Programs And Chronic Absenteeism In Elementary Schools, Aubryn Street

Electronic Theses and Dissertations

Chronic absenteeism is a common challenge in elementary education. Schools often use attendance incentive programs, such as rewards or recognition, to encourage students to attend regularly. However, it is not always clear whether these programs actually improve attendance. This study examined whether attendance incentive programs are effective and how school staff view and use these programs.

This mixed-methods study used both school attendance data and interviews with school personnel. Attendance data from two school years showed that schools with incentive programs did not have lower absenteeism rates than schools without them. However, attendance improved overall from one year to the …


Bergsonian Blend: Subjective Temporality Within Modernist Aesthetics Of Mental Illness, Lydia Victoria Gervais May 2026

Bergsonian Blend: Subjective Temporality Within Modernist Aesthetics Of Mental Illness, Lydia Victoria Gervais

Electronic Theses and Dissertations

Henri Bergson was a modernist French philosopher who wrote extensively on the topic of the lived experience of time, which he called durée, or duration. His contemporary, Sigmund Freud, was developing psychoanalytic theory in a growing field of psychological study, which serves as a prominent ancestor to modern psychiatry and current psychoanalytical literary studies. Fiction writers of the 1900s absorbed the zeitgeist of melded chronology and consciousness, interweaving themes of time and trauma in their works. Utilizing Henri Bergson’s durée as a philosophical framework, I examine the moralization of time-consciousness in connection with mental illness and investigate representations of …


Addressing Substance Use Disorder In Rural Appalachia: Improving Access And Treatment Outcomes For Justice-Involved Individuals, Jessica Muldowney May 2026

Addressing Substance Use Disorder In Rural Appalachia: Improving Access And Treatment Outcomes For Justice-Involved Individuals, Jessica Muldowney

Electronic Theses and Dissertations

Background: Opioid use disorder (OUD) represents a critical public health crisis disproportionately affecting justice-involved (JI) populations, with approximately 65% of incarcerated individuals having substance use disorders (James & Beatty, 2006). Rural Appalachian communities face compounded challenges due to limited healthcare access, provider shortages, and cultural stigma surrounding addiction treatment. Despite evidence demonstrating that medication-assisted treatment (MAT) reduces recidivism and overdose deaths, only 20% of correctional facilities offer these services (Klein & Seppala, 2019).

Objective: This mixed-methods study evaluated organizational readiness and infrastructure capacity for implementing evidence-based OUD interventions, specifically MAT programs across three rural counties in northwestern North Carolina.

Methods: …

Ontogeny And The Effects Of Perinatal Stress In The First Immature Skeleton Of Teleoceras Aepysoma (Perissodactyla, Rhinocerotidae), Joe Gajewski

Electronic Theses and Dissertations

Recovery of an immature fossil rhinoceros (Teleoceras aepysoma) skeleton (ETMNH 32999) from the Gray Fossil Site in Tennessee offers the first insights into the ontogeny of the species. ETMNH 32999 is interpreted to be a subadult male in an age class equivalent to ~17-20% of potential lifespan. Comparative analyses support the hypothesis that subadults of related taxa are typically ~91% of average adult size in most dimensions. However, certain cranial dimensions are substantially lower than expected in ETMNH 32999, averaging only ~74% of the average conspecific adult. Such departure from typical growth rates is suggested to be attributable …


Utilizing Physics Informed Neural Networks For Disrupted Signal Dynamics, Nicholas J. Joyner May 2026

Utilizing Physics Informed Neural Networks For Disrupted Signal Dynamics, Nicholas J. Joyner

Electronic Theses and Dissertations

Physics-informed neural networks (PINNs) have been used in many applications including engineering and physical sciences. PINNs allow the incorporation of a priori understanding of a process’ structure into the modeling. We attempt to leverage the PINN structure toward the evaluation of disruptions to classical dynamical models by combining elements of ordinary differential equations into our loss function with sigmoidal gating to balance the penalties for deviations from the data with those for structural deviations. This enables the identification of the signal structure and the limits of disruption influence. As a use case, we consider stock value from 2019-2021, which expresses …

Machine-Learning Landslide Susceptibility And Runout Modeling In The Nolichucky River Gorge After Hurricane Helene, Grace Braver May 2026

Machine-Learning Landslide Susceptibility And Runout Modeling In The Nolichucky River Gorge After Hurricane Helene, Grace Braver

Electronic Theses and Dissertations

Extreme rainfall from Hurricane Helene (September 2024) triggered widespread landslides across the southern Appalachian region, highlighting the need for rapid landslide susceptibility assessments that capture both landslide initiation and downstream runout. Traditional susceptibility models often focus solely on initiation zones, limiting their ability to identify which slopes will generate destructive landslides or where material will travel. This study addresses that gap by (1) integrating Geographic Information System (GIS)-based machine learning susceptibility modeling using ArcGIS Pro: Maximum Entropy (MaxEnt) and Random Forest-Based and Boosted Classification and Regression (FBBC) and (2) the U.S. Geological Survey (USGS) Grfin (Growth, Flow, and Inundation) runout …


Attitudes Toward Harm Reduction Among Criminal Legal Staff, Diamond Meadows May 2026

Attitudes Toward Harm Reduction Among Criminal Legal Staff, Diamond Meadows

Electronic Theses and Dissertations

Substance use disorders (SUDs) are prevalent among individuals interacting with the criminal legal system (Moore et al., 2019). Despite the high rates of individuals with SUDs interacting with the criminal legal system, there continue to be barriers to integrating harm reduction approaches within the system. Harm reduction approaches (i.e., medication assisted treatment) are effective in reducing the negative consequences associated with substance use and the pathway to recovery for many. The purposes of this study are to: 1. examine the psychometric properties of the Harm Reduction Acceptability Scale (HRAS) among criminal legal staff, 2. explore individual differences in staff attitudes …


Rationalizing Atrocity: Vindicatory Careerism And Mass Murder As A Career Path, 1939-1943, Bethany G. Bare May 2026

Rationalizing Atrocity: Vindicatory Careerism And Mass Murder As A Career Path, 1939-1943, Bethany G. Bare

Electronic Theses and Dissertations

This study examines members of the Nazi Schutzstaffel from an occupational perspective, focusing on how professional roles shaped their participation in systematic mass murder. As National Socialism gained influence in interwar Germany, it coincided with the rise of a generation of ambitious and embittered men eager to distinguish themselves. The transition from the T4 Program (1939-1941), the involuntary euthanasia of disabled Germans, to Operation Reinhard (1942-1943), the extermination of Polish Jews, demonstrates how mass murder evolved into a career path, as each of the men examined served as T4 personnel before transferring to Poland to assume positions as extermination camp …


Durable, Distributed Llm Inference On Cots Devices, Brycen E. Dunn May 2026

Durable, Distributed Llm Inference On Cots Devices, Brycen E. Dunn

Electronic Theses and Dissertations

The literature examines the multifaceted components of the transition process, including Kohler’s Taxonomy 2.0 and Schlossberg’s Transition Framework.

Data were collected using a one-on-one, semi-structured interview protocol to examine educators' perceptions of their roles in students' post-secondary transition. This strategy allowed the researcher to understand the participants' backgrounds and experiences while analyzing perceptions of their role in the post-secondary transition. A pre-designed set of interview …


"Am I A Man Or A Muppet": A Rhetorical Analysis Of Generative Ai’S Representation Of Gender, Jessica Boaz May 2026

"Am I A Man Or A Muppet": A Rhetorical Analysis Of Generative Ai’S Representation Of Gender, Jessica Boaz

Electronic Theses and Dissertations

This thesis examines how generative artificial intelligence constructs and performs gender roles through a rhetorical analysis of the fully AI-generated podcast Fairytale Forensics. Drawing on theories of constitutive rhetoric, stereotyping, and McLuhan’s approach to the medium, this thesis investigates how AI-generated hosts interpret classic fairy tales while simultaneously reproducing and negotiating gender norms through the lens of prosopopoeia, metonymy and synecdoche. These performances rely on normative gender stereotypes that align with broader societal expectations, thereby potentially reinforcing existing cultural assumptions about masculinity and femininity. Ultimately, it demonstrates that AI-generated discourse does not merely reflect human biases but actively participates in …


Attachment And Betrayal: Post-Infidelity Attachment Issues With A Focus On Gender, Taylor Forsythe May 2026

Attachment And Betrayal: Post-Infidelity Attachment Issues With A Focus On Gender, Taylor Forsythe

Electronic Theses and Dissertations

Infidelity represents a significant relational trauma that may disturb attachment processes such as trust, emotional intimacy, and closeness. There is a gap in the literature on how different infidelity exposures may relate to these attachment responses; more so, there is a dearth of information on the gender differences for attachment issues following any kind of infidelity. The purpose of this study aimed to examine differences in avoidant and anxious attachment across infidelity groups (no infidelity, non-sexual infidelity, sexual infidelity), and a further comparison of gender differences in those groups. Participants (N = 151) completed online surveys in a larger study …


Post-Exercise Vitals Recovery Response In Barrel Horses: A Field Study On Cooling Methods Used By Competitors, Lauran E. Hetrick May 2026

Post-Exercise Vitals Recovery Response In Barrel Horses: A Field Study On Cooling Methods Used By Competitors, Lauran E. Hetrick

Electronic Theses and Dissertations

Barrel racing demands peak physical performance from equine athletes, yet limited research evaluates the field-based strategies used to optimize equine recovery at competition. This study assessed recovery management approaches used by competitors to elucidate their influence of physiological recovery by measuring heart rate, respiratory rate, and body temperature during a high-profile barrel race competition. Physiological data were collected at baseline, immediately post-exercise, and during a 15–30-minute cooldown period to characterize recovery under real-world conditions. Significant increases in HR, RR, and BT occurred from baseline to post-run (p < 0.001), followed by reductions during cooldown (p < 0.01), though values remained elevated (p < 0.05). Rinsing reduced HR and RR (p < 0.01), while shade and fans decreased RR and variably influenced HR. Noise, as a confounding variable, decreased HR but increased BT (p < 0.001). Ultimately, these results emphasize multimodal recovery approaches in competitive equine management in the field.

From Mono To Object: A Contextual Evolution Of R&B And Soul Vocal Production Techniques With Emphasis On Object-Based Audio In Dolby Atmos, Samuel W. Slape

Electronic Theses and Dissertations

The human voice is the central element in much of recorded commercial music, and in R&B it serves as the primary vehicle of expression. Across the evolution of reproduction formats, including mono, stereo, surround, and Dolby Atmos, engineers have adapted strategies to preserve vocal clarity while exploring new spatial possibilities. This thesis examines how these shifts in technology and perception have shaped vocal production, using R&B as a lens for the relationship between format and artistic practice. Psychoacoustics provides a foundation for understanding how listeners perceive localization, masking, and vocal prominence. Analytical approaches are introduced to distinguish direct and indirect …


Bass And Drum Grooves In R&B: Analysis And Composition, Hugh Taylor May 2026

Bass And Drum Grooves In R&B: Analysis And Composition, Hugh Taylor

Electronic Theses and Dissertations

The term “R&B” has existed within the musical lexicon for nearly eighty years. It was first introduced in 1949 to replace the label “race music,” and was a combination of blues, jazz, gospel, and rock. Since then, the genre has transitioned from swing-based, live instrumentation toward straight-eighth backbeats and electronically produced sounds. Despite these shifts, contemporary R&B continues to borrow from its ancestral roots while maintaining a modern aesthetic. A primary feature that has persisted through this landscape is the “groove,” specifically defined here as the rhythmic layer created by the drums and bass. In R&B, the bass provides both …


The Incredible Is, Justin L. Hughes May 2026

The Incredible Is, Justin L. Hughes

Electronic Theses and Dissertations

The Incredible Is is a full-length philosophical play in two acts that follows Self — a man whose body contains the visible cosmos — as he travels existence with his companion Cosmic Cat in search of his creator, the "Ultimate Personifier." Along the way he encounters personified abstractions including You, Them, We, Power, Pleasure and Pain, Creator and Destroyer, and falls in love with Magic. When his obsession with finding his maker leads him to break the Rules and plunge the universe into chaos, God resets reality and Self at last confronts the Ultimate Personifier — only to discover a …


Thinking Beyond Bias: The Confirmation Bias Index And The Cognitive–Motivational Predictors Of Accurate Headline Evaluation, Anthony Cantu May 2026

Thinking Beyond Bias: The Confirmation Bias Index And The Cognitive–Motivational Predictors Of Accurate Headline Evaluation, Anthony Cantu

Electronic Theses and Dissertations

Confirmation bias — the tendency to favor belief-consistent information over contradictory evidence — represents a central challenge in contemporary misinformation research, yet its behavioral measurement has remained inconsistent across studies. This study introduced the Confirmation Bias Index (CBI), a preregistered behavioral measure defined as the difference in accuracy between ideologically congruent and incongruent headline evaluations. Using a 3 (headline slant: Conservative, Neutral, Liberal) × 2 (veracity: True, False) within-participants design, 198 participants evaluated 36 validated news headlines for accuracy. Results supported a veracity main effect and a reliable group-level confirmation bias effect indexed by the CBI. Headline slant alone did …
