Understanding Dementia Challenges In Rural Ghana: A Systematic Review, Diana Maame Agyeiwaa Agyei, Sesi Sedegah, Abena Abokoma Asemanyi, Theresa Ayertey, Wendy Yeboah

Iowa Journal of Communication

Dementia poses an escalating public health challenge in Ghana due to an expanding aging population, yet rural awareness remains critically low. Guided by Mohan Dutta’s Culture-Centered Approach (CCA), this PRISMA-compliant qualitative systematic review synthesized ten peer-reviewed articles to examine cultural perceptions and lived experiences surrounding dementia in rural Ghana. The findings highlight that cognitive decline is widely misattributed to witchcraft or normalized as standard aging. Witchcraft misconceptions subject individuals—especially older women—to severe stigmatization, social exclusion, physical abuse, and banishment to "witch camps". Meanwhile, normalizing symptoms as ordinary aging delays critical medical care and shifts family decision-making away from patients. Furthermore, …

Rest My Case: Sleep Science Should Inform J.D. Program Structures And Licensure Examinations To Enhance Performance, Equity And Well-Being, Laura J. Mott, Paula J. Manning

Minnesota Journal of Law, Science & Technology

This Article critically examines the legal profession’s longstanding marginalization of sleep and circadian biology and argues that temporal structural norms embedded in legal education and licensure are at odds with established scientific evidence. Drawing on extensive and interdisciplinary research in neuroscience, chronobiology, cognitive psychology, and timekeeping, this Article explores how sleep deprivation and chronotype misalignment with institutional schedules impair attention, memory, emotional regulation, mental and physical health, and decision-making—capacities that are essential to competent, ethical, and sustainable legal practice. Despite robust scientific consensus that sleep quality, quantity, and timing have profound effects on performance and well-being, law schools and licensing …

Parental Distress, Coercive Control With Food, And Child Self-Regulation, Kattie Nguyen

UNF Graduate Theses and Dissertations

Self-regulation is the management of one's emotions, thoughts, and behaviors to adapt to a situation (Smith-Donald et al., 2007). During infancy and toddlerhood, parents foster self-regulation through co-regulation (e.g., sensitivity, responsiveness), helping children manage their emotions, behaviors, and thoughts (Butler & Randall, 2013). Parents who experience distress (e.g., depression, stress, anxiety) are more likely to use less responsive and harsher, controlling practices like coercive control. Coercive control with food is a practice where parents use food as threats or bribes to control their child’s emotions and behaviors (Vaughn et al., 2016). The present study examined the associations between parental distress, …

Cryptic Social Mechanisms And Associated Consequences In The Gouldian Finch, Thomas Mateo

UNF Graduate Theses and Dissertations

Many species of birds rely on visual displays to communicate information to their conspecifics, but it can be difficult to determine the specific functions of such displays. In the Gouldian Finch and its relatives, the contexts in which the peering display has been witnessed indicate that it has multiple uses in social learning such as song learning and communicating reproductive intent. Two flocks of finches were housed separately at the University of North Florida aviary and observed for several months while nest boxes were placed in each habitat. In both flocks, peering increased during the summer molt, but did not …

"Donald Trump Is Definitely Fucking Satan": South Park, Media Satire, And Shifting Frames Of Acceptance And Rejection For Two Trump Presidencies, Matt Foy

Iowa Journal of Communication

In light of evolving questions of the role and efficacy of political humor in addressing the exigency of a second Donald Trump presidency, this study analyzes two extended satirical story arcs critical of Trump and MAGA from award-winning adult animated comedy South Park. The study utilizes three of Kenneth Burke’s rhetorical frames of acceptance and rejection (comedy, tragedy, and burlesque) to contrast South Park’s two most substantive satirical statements on Trump and MAGA: Season 19 and 20’s comparatively humane and introspective satire on Trump’s 2015-16 candidacy and Season 27-28’s dehumanizing mockery of Trump’s ongoing second presidency (2025-). The analysis suggests …

The Uncanny And Uneasy: An Exploration Into Using Puppets To Share Dark Stories, Grace Auls

Graduate Studies Theses and Dissertations 2026

In this thesis, I will explore the role of puppetry and practical effects in evoking the uncanny and the uneasy as well as questioning the implications they have in dark theater and cinematic contexts. This paper will examine how puppetry and practical effects can contribute to potentially disturbing and dark imagery both on screen and in live theater. I will be focusing on looking at Jim Henson’s The Dark Crystal, as well as at different puppetry performances used in Voyage of the Little Mermaid (1992), Don’t Hug Me I’m Scared, Kirikou and the Sorceress (Kirikou et la Sorciere), and even …

These relationships are overcast by her loss, her skewed reality, and her conflicting desires to …

Improvisational Theatre And Theatre Of The Oppressed: Fostering Growth In Myself And Beyond, Leigh S. Green

Graduate Studies Theses and Dissertations 2026

This thesis examines how improvisational theatre and Augusto Boal’s Theatre of the Oppressed function independently and how these practices have shaped me as both an artist and educator. Having grown up with improvisation and continued working professionally in performance and education, I have observed how it creates conditions that support development. Guided by a qualitative practice-as-research methodology, in which my own artistic and pedagogical practice serves as both site and subject of inquiry, this study explores three central questions: How does improvisational theatre contribute to youth development? In what ways can Theatre of the Oppressed deepen or reshape improvisation’s developmental …

In “Demons,” a recruit undergoing the chaotic and brutal grind of Parris Island begins to wonder if his drill instructors are possessed. “Kill Bodies” chronicles the repeated killing of …

Cell Type-Specific Fatty Acid Signalling And Its Sex Dependence, Emeline Masterson

Graduate Studies Theses and Dissertations 2026

Dietary fat is a highly palatable, energy-dense nutrient whose oral detection powerfully shapes ingestion patterns and metabolic outcomes. Despite clear behavioral and physiological evidence that fat can evoke distinct taste signals, the cellular and molecular mechanisms underlying its transduction remain poorly understood. A critical gap exists in our understanding of the cell-type-specific molecular pathways and how these signals are modulated by hormonal status. This dissertation delineates estrogen-dependent plasticity in FA transduction within the peripheral taste system, revealing coordinated, sex and cell-type-specific modulation of these pathways. To understand the missing mechanisms, FA-evoked responses were compared in Type II cells from wild-type …

Exploring The Role Of Hes4 During Retroviral Infection, Raphael Opoku

Graduate Studies Theses and Dissertations 2026

Human immunodeficiency virus (HIV) infection disrupts immune homeostasis and impairs antiviral defenses, partly by compromising natural killer (NK) cell activity, with simian immunodeficiency virus (SIV) infection in rhesus macaques serving as a valuable model to investigate these mechanisms. This research examines the regulatory role of HES4 and its isoforms in NK cell function during retroviral infection, with particular focus on how Notch signaling–dependent regulation of HES4 shapes NK effector responses. HES4, a downstream effector of the Notch signaling pathway, encodes transcriptional repressors central to immune cell differentiation, yet its contribution to NK cell biology remains poorly understood. Using molecular and …

Graduate Studies Theses and Dissertations 2026

In art, there lives a gift of transcendence with power to transport the viewer into another realm of thought and imagination beyond the limitations of our physical world. This thesis, Magic in the Margins: A Painter’s Ode to Love, Loss, and Laughter, is an exploration of the ways art can serve as both sanctuary and vessel for storytelling. Satire is used to criticize vices, and subtle humor is my tool to resonate serious content necessary for authentic self-reflection. I am investigating how to use painting as a means to make deeply intimate and visceral connections. Each canvas exploring the innermost, …

Source Credibility And Chatbots: How Design Factors Impact Chatbot Effectiveness, Kristen M. Schmidt

Graduate Studies Theses and Dissertations 2026

Source credibility theory states that the more credible a source appears to be, the more likely one is to believe both true and untrue information from it. In the modern day, misinformation is considered a major problem, particularly with virtual communication, meaning it is essential to study what factors influence a system’s source credibility. Virtual agents are a particularly relevant subject of study given that their source credibility can be impacted by both technological and social factors. Across three experiments, this dissertation utilized a novel chatbot interaction design to test how varying design factors would impact a chatbot’s source credibility …

Forest Island Reforestation In The Llanos De Moxos, Bolivia, Ethan Tam

Graduate Studies Theses and Dissertations 2026

Within the Llanos de Moxos of Bolivia thousands of forest islands dot the landscape. These forest islands have been shown to have been integral aspects of the pre-Contact indigenous cultures which existed there for thousands of years. Based on 1967 CORONA imagery and statistical analysis, this work provides insight into how these forest islands are integrated as infrastructure features within their landscape and surrounding network of other archaeological features. This research is carried out through investigations into changes in the size of the forest islands across an interval of 57 years, statistical attempts to categorize the forest island into smaller …

Building Eden Where We Can, Ireland Thomas

Graduate Studies Theses and Dissertations 2026

Building Eden Where We Can is a nonfiction memoir told in vignettes that come together to build a wider story. Through these vignettes, we are shown a narrator who is simultaneously surviving an abusive family, navigating a rare diagnosis, and coming to terms with their queerness. By braiding narratives and maintaining these various threads, this collection examines the intersections of sickness and religion, tradition and freedom, as well as fear and love. The lattermost dichotomy is represented in the narrator’s ultimate choice to leave behind a life of fear in the mother figure’s safe cage. In exchange, they receive a …

The Effects Of Episodic Facilitation And Immersion On Memory Formation During Learning Of An Exterior Preflight Inspection Procedure, Nathan A. Sonnenfeld

Graduate Studies Theses and Dissertations 2026

This research examined the use of episodic facilitation—instructional elements aligned with episodic memory (EM) processes—to affect learners’ memory of simulation training for an aviation procedure. Despite its assumed benefits in industry and theory, virtual reality (VR) has shown limited advantages over conventional media for training procedures, in part because prevailing frameworks emphasize semantic and procedural outcomes, leaving memory of training experiences as events underexamined. To address this gap, this work advances human factors research by examining EM as a design consideration, an outcome, and an explanatory mechanism for how simulation training experiences are remembered. Grounded in theories of EM and …

Using Inferences From Natural Language Narratives To Improve Video Question Answering, Hoang Bao Truong

Graduate Studies Theses and Dissertations 2026

The purpose of this thesis is to examine how structured narrative representation and reasoning strategies jointly affect the performance of Video Question Answering (VideoQA). Although recent advances in large multimodal and language models have improved video description and retrieval, causal and counterfactual reasoning remain challenging. This thesis studies an inference-only pipeline in which videos are converted into natural-language narratives, and those narratives may optionally be transformed into a structured NarrativeML format before multiple-choice questions are answered without task-specific fine-tuning. NarrativeML is a machine-readable narrative representation that explicitly encodes entities, events, and their causal and temporal relations. Three representational contexts are …

Sonic Costumes For Immersive Theme Park Storytelling: Developing Interactive Wearables To Enhance Performer, Audience, And Environment Interaction, Rachel Yee

Graduate Studies Theses and Dissertations 2026

Costumes enhance the themed experience through visual storytelling while also allowing performers to interact fluidly with a physical space. These garments are typically passive storytellers in theme parks, even if the performers interact directly with guests. Some garments coordinate with and react to elements of the themed environment, predominantly when worn by performers within live shows, parades, or streetmosphere settings. However, this interactivity is often available only at a distance from guests, causing a separation between audience and performer. For instance, lights on parade costumes, such as those throughout Disney’s Magic Kingdom Park, often synchronize only with parade floats and …

Fgf19 As A Colorectal Cancer Serum Biomarker And Fgfr4 As A Mediator Of Anti-Her2 Resistance In Breast Cancer, Jordan Beardsley

Graduate Studies Theses and Dissertations 2026

The fibroblast growth factor 19 (FGF19)-fibroblast growth factor receptor 4 (FGFR4) signaling pathway regulates hepatic metabolism, bile acid (BA) synthesis, and hepatocyte proliferation. This signaling axis also is implicated in promoting tumor progression, therapeutic resistance, and metastasis in certain cancers.

In colorectal cancer (CRC) there is a critical need for non-invasive biomarkers for disease detection and monitoring. We identified FGF19 as a candidate CRC serum marker through meta-transcriptomics and found FGF19 to be expressed and secreted by CRC cell lines. Tumor-derived FGF19 was detectable in mouse serum at levels correlating with tumor volume in a subcutaneous xenograft model. RNA sequencing …

Pioglitazone Uncouples Macrophage Inflammatory Signaling From Epithelial Oxidative Stress During Map Infection Mimicking Crohn’S Disease Treatment, Sabera Akter Bushra

Graduate Studies Theses and Dissertations 2026

Crohn’s disease (CD) is a chronic inflammatory bowel disease characterized by intestinal inflammation, epithelial barrier dysfunction, and abnormal immune signaling. CD pathophysiology is increasingly linked to Mycobacterium avium subspecies paratuberculosis (MAP) infection, which increases chronic macrophage activation and the production of inflammatory mediators that lead to epithelial damage. Among these mediators, CXCL10, TNF-α, and IL-6 contribute in inflammation, while NOX-1 and SERPINE-1 indicate epithelial oxidative stress and damage. Despite the role of macrophage-epithelial interaction in CD, selective pharmaceutical regulation of this axis remains unclear. Pioglitazone, an FDA-approved PPARγ agonist used for type 2 diabetes, is an appealing repurposing candidate, given …

Towards An Understanding Of Learning In Immersive Virtual Reality: Investigating Learning Affordances To Bridge Theory And Practice, Gregory Mcgowin

Graduate Studies Theses and Dissertations 2026

This dissertation examines how modality-specific scaffolding shapes performance, presence, and transfer in immersive virtual reality (I-VR). Framed through theories of extended cognition, real-time guidance is conceptualized as cognitive scaffolding that structures perception and action by embedding task-relevant information within the environment. Situated within the learning sciences and informed by 4E cognition (embodied, embedded, enactive, extended), this work develops a framework for understanding how I-VR affordances relate to learning and performance.

The empirical study investigates how scaffolding modality (audio vs. visual) influences presence and performance in a VR racing simulation. Using a 3 × 2 × 2 mixed factorial design, 111 …

“How Far Do These Roots Go Down”: An Exploration Of Latinx And Latina Fans On Representation In Disney's Encanto, Noemi Nunez

Graduate Studies Theses and Dissertations 2026

In this dissertation, I examine how Latinx and Latina audiences engaged with and interpreted Disney’s 2021 Encanto, an animated film celebrated for its representation of Colombian and broader Latinx culture. While scholarship on Latinx representation in media has expanded, less attention has been given to how Latinx audiences themselves respond to narratives that are meant to represent them, particularly within fan studies. Focusing on both a broader Latinx fan community and first-generation Latinas in the United States, this project explores how audiences negotiate representation and recognition using Encanto as a media text that centered a Latinx story. Drawing from …

Between A Rockpile And A Hard Place: Mapping The Folk-Hydronymy Of Southern New England, Amanda Gilmore

Open Access Master's Theses

Fishermen in Southern New England (SNE) utilize a wide variety of placenames to delineate areas of significance on the open ocean. This information provides new revelations not just about the way fishermen navigate the ocean, but also insight about overlaps between Local Ecological Knowledge (LEK) and Fishermen’s Ecological Knowledge in the historically prolific fishing sector of Southern New England. Prior to this study, this collection of vernacular place names on the water, or folk-hydronymy, had never been documented or analyzed, as it was held almost entirely in cognitive maps and proliferated through communication with other fishermen. This project’s goal was …
