Evaluation Of A Community-Based Socialization Program For Independently Living Older Adults, Patricia A. Shane, Anne T. Ferguson, Erin L. Woodhead

Faculty Research, Scholarly, and Creative Activity

Social isolation among older adults is a major public health concern because of the adverse impact it has on health and well-being. Reducing social isolation can improve health and decrease the use of costly healthcare services. However, there is little consensus on the critical ingredients of programming to reduce social isolation. Bay Area Older Adults® (BAO) is a nonprofit organization whose community-based Healthy Living Program (HLP) focuses on building and nourishing older adults’ social networks through transitions such as retirement, divorce and loss of loved ones. The current study was a program evaluation of the HLP using a survey to …

Validation Of A Self-Fitting Over-The-Counter Hearing Aid Intervention Compared With A Clinician-Fitted Hearing Aid Intervention: A Within-Subjects Crossover Design Using The Same Device, Lucas S. Baltzell, Kosta Kokkinakis, Amy Li, Anusha Yellamsetty, Katherine Teece, Peggy B. Nelson

Faculty Research, Scholarly, and Creative Activity

In October of 2022, the US Food and Drug Administration finalized regulations establishing the category of self-fitting over-the-counter (OTC) hearing aids, intended to reduce barriers to hearing aid adoption for individuals with self-perceived mild to moderate hearing loss. Since then a number of self-fitting OTC hearing aids have entered the market, and a small number of published studies have demonstrated the effectiveness of a self-fitted OTC intervention against a traditional clinician-fitted intervention. Given the variety of self-fitting approaches available, and the small number of studies demonstrating effectiveness, the goal of the present study was to evaluate the effectiveness of a …

Early Electronic Journals: A Preservation Survey, Nick Szydlowski, Rosa Salangsang, Daniella Kate Corpuz

Faculty Research, Scholarly, and Creative Activity

In 1994, the Association of Research Libraries (ARL) published a print directory containing information on every electronic journal that could be identified, anywhere in the world. Thirty years later, this study surveys the current availability and preservation status of those 443 journals. While a significant number of these journals are no longer available, the results indicate that independent preservation efforts by individuals and small groups were a major factor in preserving many of the remaining publications. This study uses the preservation survey method to assess the preservation environment for these journals, and also to build an online directory of the …

Can Household Water Sharing Advance Water Security? An Integrative Review Of Water Entitlements And Entitlement Failures, Melissa Beresford, Ellis Adams, Jessica Budds, Leila M. Harris, Wendy Jepson, Tennille Marley, Chloe Nguyen, Amber Pearson, Anaís Delilah Roque, Asher Y. Rosinger, Sameer H. Shah, Matthew Stellbauer, Amber Wutich

Faculty Research, Scholarly, and Creative Activity

An increasing number of studies find that water sharing—the non-market transfer of privately held water between households—is a ubiquitous informal practice around the world and a primary way that households respond to water insecurity. Yet, a key question about household water sharing remains: is water sharing a viable path that can help advance household water security? Or should water sharing be understood as a symptom of water insecurity in wait for more formalized solutions? Here, we address this question by applying Sen’s entitlement framework in an integrative review of empirical scholarship on household water sharing. Our review shows that when …

The questions addressed how teacher morale affected the teachers according to the number of years they had been teaching, their college majors, their highest college degree, their gender, and their ethnicity. The teachers who participated in this study were volunteers who had to be teaching for 2 years or more.

This was a quantitative study that used the Teacher Rapport With Principal dimension of the Purdue Teacher Opinionnaire …

The Lived Experiences Of Project Rebound Students In California, Jeffrey R. Jacobs

Theses and Dissertations

As the United States attempts to address issues of prison overcrowding, recidivism, and rehabilitation, states like California have turned to higher education during and after incarceration to remedy the situation and promote successful community reentry among individuals who have served time in the nation’s prisons. People who are formerly incarcerated are often up against a myriad of obstacles once released, and programs like California State University’s Project Rebound aim to aid in this transition through a model rooted in community and campus care. Numerous bodies of research have explored the impacts of education on individuals who are actively incarcerated; however, …

Egalitarianism Is Not Equality: Moving From Outcome To Process In The Study Of Human Political Organisation, Duncan Stibbard-Hawkes, Christopher Von Rueden

Jepson School of Leadership Studies articles, book chapters and other publications

Many traditional subsistence groups have been described as ‘egalitarian societies’. Definitions of ‘egalitarianism’, especially beyond anthropology, have often emphasised equality in resource access, prestige or rank, alongside generalised preferences for fairness and equality. However, there are no human societies where equality is genuinely realised in all areas of life. Here we demonstrate, empirically, that nominally egalitarian societies are often unequal across seven important interconnected domains: embodied capital, social capital, leadership, gender, age/knowledge, material capital/land tenure, and reproduction. We also highlight evidence that individuals in nominally egalitarian societies do not unfailingly adhere to strong equality preferences. We propose a new operational …

Corporate Scenarios: Drawing Lessons From History, Madison Condon

Faculty Scholarship

As corporations are increasingly pressed to reveal information about their exposure to climate-related risks, they are often asked to undertake and disclose the outcome of “scenario analysis.” In this exercise, corporations, including financial institutions, examine how their business would fare under different pathways the future may take. One oft-used scenario, for example, is the International Energy Agency’s “Net-Zero by 2050: A Roadmap for the Energy Sector.” This Essay presents a history of the use of scenarios as a corporate planning tool, particularly in the oil industry, arguing that it is key for understanding our present moment and the role of …

Finite Element Modeling For Two-Dimensional Wireless Capsule Endoscope Manipulation System, Wael S. Abbas, Mohamed T. El-Wakad, R.R. Darwish

Trends in advanced sciences and technology

The inadequacies of traditional flexible endoscopes used in gastrointestinal diagnostic procedures, causing pain and discomfort to patients, led to the development of the wireless capsule endoscope. There are two types of wireless capsule endoscopes: passive and active. The passive wireless capsule endoscope cannot stop at a specific position for diagnostic purposes, which can lead to capsule retention. The active capsule can solve those problems. In this article, we use COMSOL Multiphysics to simulate a two-dimensional (2D) electromagnetic actuation (EMA) system for active wireless capsule endoscope. The EMA system uses a stationary two-pair coil system (Helmholtz and Maxwell). The capsule endoscope …

Genetic Mutations Affecting Dentin Formation: Molecular Insights And Therapeutic Strategies, Mohamed Yehia Abdelfattah, Yara Sameh Said, Shimaa A. Elsaady, Shahenda A. Abdallahahmed, Wael Abou-Zeid

Trends in advanced sciences and technology

Writing a comprehensive review on gene mutations affecting dentin mineralization requires thorough research and organization, as each section examines how specific mutations influence this process, supported by relevant findings. Mutations in genes such as DSPP, DMP1, andMEPE impair dentin structure and mineralization by disrupting odontoblast function, dentin matrix integrity, and mineral deposition. These genetic alterations interfere with key biological processes, including odontoblast differentiation and matrix formation, through altered signaling pathways such as Wnt/β- catenin and TGF-β, contributing to dental disorders like Dentinogenesis Imperfecta (DI). Gaining molecular insights into these disruptions enhances our understanding of dentin biology and supports early diagnosis, …

Triboelectrostatic Separation Of Lunar Regolith, Hannah Peterson

Dissertations, Master's Theses and Master's Reports

Lunar regolith as a source of raw materials for a long-term human presence on the moon would need to be separated into single mineral fractions. To do this, triboelectric properties can be utilized to separate minerals without needing to add a working fluid, such as air and water, or expensive, consumable chemicals. A lightweight machine can be created to do this, one that also requires minimal electricity. A series of three prototypes for this machine were created and tested to determine if this concept would work, and what properties the machine would need. A mixture of magnetite and silica were …

Transformer Models For Paraphrase Detection: A Comprehensive Semantic Similarity Study, Dianeliz Ortiz Martes, Evan Gunderson, Caitlin Neuman, Nezamoddin N. Kachouie

Mathematics and System Engineering Faculty Publications

Semantic similarity, the task of determining whether two sentences convey the same meaning, is central to applications such as paraphrase detection, semantic search, and question answering. Despite the widespread adoption of transformer-based models for this task, their performance is influenced by both the choice of similarity measure and BERT (bert-base-nli-mean-tokens), RoBERTa (all-roberta-large-v1), and MPNet (all-mpnet-base-v2) on the Microsoft Research Paraphrase Corpus (MRPC). Sentence embeddings were compared using cosine similarity, dot product, Manhattan distance, and Euclidean distance, with thresholds optimized for accuracy, balanced accuracy, and F1-score. Results indicate a consistent advantage for MPNet, which achieved the highest accuracy (75.6%), balanced accuracy …

Homelands Not Graveyards, M. Alexander Pearl

Faculty Articles

Within the last five years, the U.S. Supreme Court has taken up several transformative cases affecting Native nations and federal Indian law jurisprudence. The Supreme Court’s decision in Arizona v. Navajo Nation is no different. This Article examines that decision and situates it within that legal history as well as the realities of present-day water resource availability. While recent decisions have shown the Court’s willingness to confirm fundamental components of federal Indian law, such as the legal tests for determining the persistence of reservation and the authority of Congress to enact the Indian Child Welfare Act, the Court’s examination of …

Undocumented Eldercare, Llc, Kit Johnson

Faculty Articles

Americans are aging. Within five years, 20% of the U.S. population will be over the age of 65. In the next 25 years, the number ofcitizens over the age of 80 is expected to triple.

Many older Americans, particularly the oldest, need help with daily lifeeverything from dressing and showering to cooking and cleaning. Assistance, however, is hard to come by. At-home caregivers are expensive. Institutional settings, also expensive, are routinely understaffed.

Thousands of noncitizens provide eldercare in home and institutional settings. Many of these noncitizens have work authorization pursuant to Temporary Protected Status (TPS), an immigration program that President …

Engineering Extracellular Vesicles (Evs) To Combat Infection And Inflammation In Cystic Fibrosis, Sharanya Sarkar

Dartmouth College Ph.D Dissertations

Cystic Fibrosis (CF) is a multisystemic genetic disorder caused by mutations in the CFTR gene, resulting in chronic pulmonary infections, hyperinflammation, and progressive lung damage. Among the pathogens that colonize CF lungs, Pseudomonas aeruginosa (P. aeruginosa) is predominant, infecting over 50% of adults with CF and developing antibiotic resistance over time. Current modulator therapies fail to address persistent bacterial infections, chronic inflammation, or irreversible lung damage, underscoring the need for novel therapeutic strategies. In our previous in vitro studies, we demonstrated that extracellular vesicles (EVs) secreted by primary Human Bronchial Epithelial Cells (HBECs) inhibit P. aeruginosa growth by reducing the …

Spatial Analysis Of American Chestnut (Castanea Dentata) Distribution And Ecology In Kentucky’S Federal Lands, Jacob Raymond Pease

Murray State Theses and Dissertations

Anthropogenic factors have been the cause of the decline of tree species across the globe. From unsustainable logging and development to disease and improper management, threats to forests have taken their toll. The American chestnut (Castanea dentata) was once an integral basal tree species in Appalachian forests, but chestnut blight drove the species to functional extinction by the mid-1900s. The recent creation of genetically modified chestnuts gives hope for future restoration of the species throughout its historical range. Despite blight resistance, effective restoration will require optimal site selection for finding and planting chestnuts, which will maximize limited resources. …

Understanding Bird Diversity: A Modeling Approach In An Urban And Wetland Ecosystem, Clay Bliznick

Murray State Theses and Dissertations

The global increase in anthropogenically-driven shifts of land cover has resulted in losses to many natural communities such as prairies and wetlands. These ecosystems take on artificially-derived characteristics such as croplands, buildings, and roads to the extent that they no longer resemble the areas they once were. This process often results in the loss of biodiversity, ecological integrity, and valuable ecosystem services in these environments. Attempts to restore the condition and function of these disturbed areas are often implemented, but due to the complexity of factors driving these restorations, there is often a lack of practical insight needed to optimize …

Strong Neighborhood-Prime Labelings Under Ordinary & Gaussian Integers, Micheal Arnal-Brown

Murray State Theses and Dissertations

This thesis introduces and studies the notion of a strong neighborhood-prime labeling, a strengthening of the neighborhood-prime labeling where the label 1 can be assigned to any vertex in a graph. We prove that several graph families—including paths, cycles (excluding those congruent to 2 modulo 4), caterpillars, helm graphs, closed helm graphs, gear graphs, and graphs with universal vertices—admit such labelings, and also provide results to more general classes of graphs. We extend this new labeling concept to the Gaussian integers using a spiral order- ing on Z[i] and define a Gaussian analogue of strongly neighborhood-primeness. To support this extension, …

Murray State Theses and Dissertations

Amid declining enrollments in teacher preparation programs and increasing teacher turnover, understanding the characteristics of Generation Z, who constitute a substantial portion of the future workforce, is critical for effective recruitment and retention in education. This quantitative study explored the preferred leadership styles of Generation Z public educators in western Kentucky using the Multifactor Leadership Questionnaire (MLQ). Specifically, it examined preferences for transformational, transactional, and passive-avoidant leadership styles and assessed whether these preferences varied by race, gender, or years of experience. Results revealed a strong preference for transformational leadership, followed by transactional leadership, with a clear aversion to passive-avoidant approaches. …

The Representation Of Feminine Beauty In Generative Artificial Intelligence Models, Haley R. Stacy

Murray State Theses and Dissertations

As Artificial Intelligence (AI) technology advances, its influence on media and societal perceptions becomes increasingly significant. This dissertation explores how popular generative visual AI models represent women and the implications for racial and body type inclusivity. This study examines women’s perceptions of AI-generated representations. Two primary research questions are being explored: (1) How do AI-generated algorithms represent women in visual outputs when prompted with broad beauty-related keywords? (2) How do women perceive their representation in these AI-generated visual outputs? Through a detailed analysis of AI-generated imagery, the research uncovers implicit and explicit biases within these systems. The research also gathered …

New Psychoactive Substances Detected In Wastewater Samples Collected Along The Interstate Highway Rest Areas In Kentucky, Durga Prasad Kodati

Murray State Theses and Dissertations

The rapid emergence and proliferation of new psychoactive substances (NPS) pose significant challenges to public health and law enforcement. The potential for abuse and toxicity of these substances, which are intended to mimic the effects of controlled drugs, has been raising concerns as these compounds are designed to evade being regulated. There are traditional methods of tracking NPS, such as seizures and forensic toxicology, but they are delayed and seldom effective because these substances continue to evolve rapidly. Wastewater-based epidemiology (WBE) has emerged as a promising tool for real-time surveillance of drug consumption. The primary objective of this research was …

Personality Assessment Inventory: The Treatment Rejection Scale & Treatment Variables, Ashlee Bradley

Murray State Theses and Dissertations

The present study aimed to identify the role and validity of the Treatment Rejection Scale (RXR), one of the treatment consideration scales on the Personality Assessment Inventory (PAI; Morey, 1991), and its relationship with treatment variables in an outpatient clinical setting. The study used archival data involving 200 client files. The current study evaluated RXR scores in relation to premature, situational, and mutual terminators. Therapist-rated process variables, such as client cancellations, the number of sessions attended, client “no-shows,” and any barriers to completing treatment from the clinician’s point of view, were also considered. Additionally, the treatment outcome variable, in the …

Unraveling Reproductive Complexity: Integrative Assessment Of White Crappie Pomoxis Annularis Spawning Dynamics In Kentucky Lake, Emily A. Freeman

Murray State Theses and Dissertations

In large reservoirs such as Kentucky Lake, White Crappie Pomoxis annularis exhibit complex reproductive dynamics, including variable annual recruitment and frequent skipped or partial spawning events. This study investigates the energetic and environmental factors influencing spawning success in Jonathan Creek, a northern embayment of Kentucky Lake. Using a dual sampling approach, I combined citizen science angler-caught fish during the pre-spawn with trap netting in shallow spawning areas to capture crappie during the full reproductive cycle. Physiological, biometric, and egg analyses revealed that spawning success was driven more by pre-spawn energetic conditions than by the conditions during the spawn. Elevated water …

The Solicitor General, Consistency, And Credibility, Margaret H. Lemos, Deborah A. Widiss

Articles by Maurer Faculty

This Article offers the first comprehensive look at cases in which the Solicitor General (SG) rejects a legal argument offered on behalf of the United States in prior litigation. Such reversals have received considerable attention in recent years, as shifts in presidential administrations have produced multiple high-profile “flip-flops”—as the Justices sometimes call them—by the SG. Even those observers who defend the SG, including veterans of the office, caution that inconsistency in legal argument poses a threat to the SG’s credibility with the Court. Our goal is to better understand the circumstances that lead the SG to change its position on …
