Discharge Process Improvement Initiative Using An N-By-T Strategy In A Progressive Care Unit In An Acute Care Setting, Sukhvir Walia

Doctor of Nursing Practice Projects

Background

Timely and efficient patient discharge processes are crucial for enhancing hospital throughput, reducing emergency department boarding, optimizing inpatient bed utilization, and ensuring safe transitions of care. Delayed hospital discharges contribute to prolonged hospitalizations, operational inefficiencies, increased healthcare expenditures, and decreased patient satisfaction. Progressive care units (PCU) are particularly vulnerable to discharge delays because patients frequently require multidisciplinary coordination before safe discharge can occur.

Purpose

The purpose of this quality improvement project was to evaluate the effectiveness of implementing a structured discharge readiness checklist combined with an n-by-T discharge planning strategy during multidisciplinary patient progressive rounds (PPRs) to improve discharge …

Mental Health Representation And Audience Interpretation In Contemporary Streaming Media, Caitlyn Freeman

Communications and Digital Media Theses

This study looks at streaming television as a place where ideas about mental health are shaped and communicated. These shows communicate mental health through storytelling, rather than simply reflected. Instead of viewing series as realistic depictions of psychological struggle, this analysis focuses on different elements to understand how audiences understand mental illness. This study focuses on patterns in how mental health is presented to audiences, including whether it is shown as an emotional conflict, ongoing experience, or a moment of crisis within the story. Using a qualitative analysis, the research analyzes selected episodes from each series through a codebook with …

Nadh Flim Reveals Cellular Bioenergetics And Mitochondrial Morphology During Drosophila Convergent Extension, Maria Espana Pena

Graduate Theses and Dissertations

Mitochondria are dynamic organelles that can fragment or fuse to support different bioenergetic demands and cellular processes, although the role of mitochondrial fission and fusion during embryonic development is not well understood. Fluorescence lifetime imaging (FLIM) of the mitochondrial cofactor NADH can be used to visualize mitochondrial networks and infer aspects of cellular bioenergetics in a label-free manner. We used NADH FLIM to test whether germband cells undergo changes in cellular metabolism during Drosophila convergent extension (CE)––a process in which hundreds of epithelial cells undergo coordinated intercalation to elongate the embryo. Contrary to our expectations, we did not observe significant …

Exploring Agricultural Pathways: An Analysis Of Arkansas Community Colleges, Natasha Hightower

The Impact Of Life Coaching On Self-Efficacy In Personal Goal Setting Among Black Educators In Arkansas, Veronica Cousette Jackson

Graduate Theses and Dissertations

This quantitative study examines the relationship between life coaching and self-efficacy in personal goal setting among Black educators in Arkansas, with gender explored as a moderating variable. Self-efficacy, grounded in Bandura’s (1997) social cognitive theory, is a central determinant of motivation and goal-directed behavior, influencing persistence, effort, and adaptive strategies. Although life coaching has gained recognition as a professional developmental practice, empirical research remains limited regarding its psychological effects within educator populations and its differential impact across demographic groups (Grant, 2014; Theeboom et al., 2014). This gap is particularly significant for Black educators, who experience disproportionate workforce stress and retention …

Old-Growth Surveys And Landowner Outreach In The Cross Timbers Of Oklahoma, Jon Webb

Graduate Theses and Dissertations

The Cross Timbers ecoregion represents a critical ecologic transition zone, spanning approximately 17 million acres across Oklahoma, Texas, Kansas, and Arkansas. Situated between eastern deciduous forests and the southern Great Plains, the Cross Timbers are dominated by drought-tolerant post oak (Quercus stellata) and blackjack oak (Quercus marilandica). Despite retaining some of the most extensive old-growth forests in the eastern United States, this ecoregion remains threatened by urban expansion, agricultural conversion, altered fire regimes, and eastern red cedar (Juniperus virginiana) encroachment. This project sought to identify, survey, and document large, previously un-surveyed or unreported tracts of old-growth Cross Timbers in Oklahoma, …

Grazed Pasture Effects On Greenhouse Gas Emissions In The Ozark Highlands, Tyler Buchanan

Graduate Theses and Dissertations

In the United States (US), grazinglands serve as the main foundation for the livestock industry, and, in Arkansas specifically, pastures are essential for rotational grazing and dairy operations. Climate change is increasingly becoming a concern in the agriculture industry, largely caused by anthropogenic activities increasing greenhouse gas (GHG) concentrations in the atmosphere, at least partly due to the nutrient recycling that occurs from animal manure additions in grazinglands. Therefore, quantifying GHG emissions from pastures is essential to better understanding the impacts of grazing on the environment. The objective of this study was to quantify and evaluate the potential effects of …

Graduate Theses and Dissertations

Nonprofit services are frequently sought by community members experiencing material hardship, particularly at junctures where employment- and state-based compensation fail to provide sufficiently. While barriers to aid provision have been examined from the perspective of nonprofits, various accessibility issues for community members seeking to obtain support are an under evaluated factor that influence the efficacy of nonprofits in carrying forth their mission. This qualitative study seeks to understand commonly experienced barriers to support facing resource-seeking community members. Semi-structured interviews with Northwest Arkansas community members, a region highly saturated with well-funded nonprofit agencies, shed light on recurring obstacles, and provide theoretical …

Does The Medium Make A Difference? A Quantitative Study Of Traditional Versus Social Media, Erin Elaine Bailey

Graduate Theses and Dissertations

People are changing why they use social media, what used to be a way to unwind and stay in touch with old friends is now being used for something much different. This study looks into how young adults (ages 18–25) perceive and retain information from social media compared to traditional media. As social media increasingly functions as both an entertainment and news source, the distinction between it and traditional journalism continues to diminish. Using a quota sample of 300 participants, data were collected through a Qualtrics survey measuring media engagement, usage, perceived credibility, and knowledge retention. Participants were exposed to …

Conservation Agriculture Effects On Greenhouse Gas Emissions From Cotton, Soybean, And Corn In Southeast Arkansas, Jonathan Benjamin Brye

Graduate Theses and Dissertations

The slow degradation of natural resources has resulted in the focus of agriculture shifting towards conservation practices, such as reduced/no-tillage, cover crops (CC), and organic amendments (i.e., biochar), that conserve and improve natural resource quality. The objectives of this thesis were to i) quantify the impacts of biochar rate (i.e., 0, 2000, and 4000 kg ha-1) and ii) the combination of CC and tillage practice on carbon dioxide (CO¬2), methane (CH4), and nitrous oxide (N2O) fluxes, growing-season-long emissions, global warming potential (GWP), soil properties, and plant response from a minimally tilled cotton (Gossypium hirsutum)-corn (Zea mays) rotation and a soybean …

The Relationship Between Sports Related Head Injuries, Mental Health And Academic Performance In University Student-Athletes, Odyssey Keller

This study aimed to address gaps in the existing literature by assessing concussion history, mental health and academic challenges …

"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 …

Assessing The Use Of Accelerometers For Measuring Static Balance Perturbations, Delaney Mcmanus

Anthropology

Falls among older adults are a leading cause of injury and loss of independence and have become an increasingly relevant public health issue as the elderly population continues to grow. Understanding the biomechanical factors that contribute to fall risk is essential in developing fall-prevention strategies and identifying individuals at risk. Force platforms are the gold-standard method for quantifying balance perturbations, but they are expensive and require dedicated lab space and support staff to operate. This research has three goals: (1) to test whether wearable accelerometers can provide similar discrimination of balance perturbations as a force plate, (2) to evaluate the …

Genomic Surveillance Of Guillain–Barré Syndrome-Associated Genes In Campylobacter Jejuni Across Human And Non-Human Reservoirs, Emma Doughty

Biological Sciences

Campylobacter jejuni is a leading cause of foodborne illness and a major trigger of Guillain–Barré Syndrome (GBS), an autoimmune neuropathy caused by molecular mimicry between bacterial lipooligosaccharides (LOS) and host nerve gangliosides. While prior genomic studies have focused primarily on human clinical isolates, the prevalence and distribution of GBS-associated genes in non-human reservoirs remain poorly characterized. This study used genomic datasets derived from analyses of human and non-human C. jejuni isolates to assess the distribution of GBS-associated genes, with a focus on the neuABC sialylation pathway. Results demonstrate that these genes are present in both host types, across multiple geographic …

Alternative Abl1 Isoform Expression In Oncogenic Translocations: Implications For Cancer Progression, Jessica Teague

Biological Sciences

Abstract (also on poster): Previous studies in our lab show that an alternate isoform of Bruton’s tyrosine kinase, BTK-C, is required for the survival of several epithelial-derived cancer cells. BTK-C is transcribed from an alternative promoter and includes a 34-amino-acid N- terminal extension with a palmitoylation sequence that alters its subcellular localization. Nine other human kinases have similar alternative N-termini (ANT), often producing palmitoylated or non-palmitoylated isoforms from different transcriptional start sites. Among these, ABL1 is a known oncogenic kinase and key drug target. Translocation mutations at the 5′ end of ABL1 are a major cause of adult leukemias. This …

Pulses are rich in carbohydrates, protein, and essential minerals, making them ideal whole foods and critical contributors to food and nutrition security. Due to these advantages, pulse breeding programs are increasingly focusing on enhancing nutritional traits, such as protein quality, amino acid balance, and micronutrient density, through the process of biofortification. However, improvement of agronomic traits remains equally essential. Characteristics such as plant height, standability, stress tolerance, …

Investigation Of Low-Pressure Mercury Lamp System Configurations And Xenon Excimer Lamp System Development As Vacuum Ultraviolet Sources For Optimal Photolytic Degradation Of Poly-/Perfluoroalkyl Substances, Eman Zuhair Alhamdan

All Dissertations

PFAS are persistent synthetic chemicals, with unique properties that enable them to easily enter and accumulate in water sources. Their public health impacts have raised concern and highlighted the need for effective treatment. Numerous techniques for PFAS removal from water have been studied, few have proven the ability of breaking down PFAS rather than separating and concentrating it. Many of these methods are chain-length dependent, showing slower degradation rate of short-chain PFAS and requiring substantial amounts of energy, and chemical agents that may produce byproducts.

Among available PFAS destruction methods, direct photolysis by high-energy UV with wavelength below 200 nm …

All Dissertations

This dissertation describes methods to analyze lengthy recordings of data in order to detect sparsely occurring activities. The narrative below describes the progression of research that led to the development of these methods and their generalization into a unified framework. My research started with designing models for dietary monitoring, including detecting meals from day-long recordings and detecting intake gestures from meal-length recordings. Both tasks share some common characteristics: (a) the target event takes only a small portion of data recordings, and (b) there is global context within full-length data recordings that can help a model make better decisions. After finishing …

Experimental And Computational Investigation Of The Effects Of Neck Musculature During Head Impacts In American Football, Anthony P. Marino

All Dissertations

Anthropometric test devices (ATDs) are human surrogate models used to represent the human body response in the context of compliance and safety testing. These devices are used in multiple industries, including automotive and aerospace, and have recently been incorporated into impact testing for the evaluation of helmet performance in American football. The Hybrid III 50^th percentile male ATD head and neck assembly is the most commonly used surrogate for these tests, although it was developed for automotive frontal crash scenarios that induce an inertial force on the body, leading to head and neck motion primarily in the sagittal plane. …

Versatile Exoskeleton Control Paradigms For Agile Human Locomotion: Task-Agnostic And Stability-Augmented Assistance, Miao Yu

All Dissertations

Lower-limb exoskeletons have shown great potential for assisting human locomotion, but designing controllers that provide assistance across diverse locomotor tasks and under external perturbations remains a major challenge. Many existing controllers for steady-state walking rely on pre-defined reference trajectories, which constrain voluntary human motion and limit adaptability across tasks. Moreover, they usually assume stable walking, while their performance under unstable conditions remains largely unexplored. In addition, existing gait stability augmentation controllers are often reactive rather than proactive to unstable conditions. In this dissertation, we propose control frameworks that preserve voluntary human motion while addressing two major challenges: providing task-agnostic assistance …

Towards Generalizable Representation Learning Across Domains, Hossein Kashiani

All Dissertations

Despite remarkable progress in deep learning, a major challenge remains: machine learning models often struggle to generalize to unseen domains under distribution shift. In real-world settings, data often differ from training conditions due to changes in lighting, sensor type, image resolution, and style. These differences can significantly degrade performance, highlighting the need for representations that are both robust and generalizable. This thesis addresses this challenge by developing a set of frameworks for generalization across domains in anomaly detection, deepfake detection, and vision-language image recognition. For anomaly detection, this thesis introduces ROADS, a robust prompt-driven framework for multi-class unified anomaly detection. …
