Uneven Terrain Treadmill Training For Lower Limb Prosthesis Users: A Feasibility Study, Brian Diep, Keegan Feroah, Ani Gasparyan, Nevena Jovanovic

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals with lower limb amputation (LLA) face an increased risk for falls which may limit mobility, confidence, and participation in daily activities. Current rehabilitation programs for this population rarely integrate surface training as an intervention, despite walking on different surfaces being a necessity to participate in the real world. This feasibility study aimed to evaluate the practicality, acceptability, and preliminary efficacy of an uneven treadmill training protocol for individuals with LLA. Five adults with LLA (P1: transfemoral, 38 years old, 1.75 m, 88.8 kg; P2: hip disarticulation, 38 years old, 1.60 m, 106.7 kg; P3: transfemoral, 53 years old, 1.81 …

Solving The 2-Sigma Problem With Chatgpt: A Case Study On The Double-Entry Accounting System, Dieudonne A. Affognon

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined whether structured ChatGPT tutoring could approximate the learning gains historically associated with one-on-one human tutoring. Grounded in cognitive load theory and informed by Bloom’s two-sigma benchmark, the investigation used double-entry accounting as a procedurally dense testbed requiring coordinated schema construction and rule-based reasoning. A randomized proof-of-concept design assigned thirty first-year accounting students to either human tutoring or ChatGPT tutoring across an eight-week instructional interval. Learning outcomes were assessed at pretest, posttest, and delayed retention. Repeated-measures analyses revealed substantial within-subject learning gains across both instructional modalities. Performance improved significantly from baseline to post-instruction assessment, indicating acquisition of procedural …

Effectiveness Of Cognitive Stimulation Therapy On The Quality Of Life Of Adults With Dementia: A Secondary Analysis, Evelyn Airam

UNLV Theses, Dissertations, Professional Papers, and Capstones

This secondary analysis study evaluated the effectiveness of Cognitive Stimulation Therapy (CST) on quality of life (QoL), depressive symptoms, and cognitive function in 108 community-dwelling older adults with cognitive impairments, including dementia. Outcomes involved Quality of Life (QoL) measured by the Quality of Life in Alzheimer’s Disease (QoL-AD), symptoms of depression by the Cornell Scale for Depression in Dementia (CSDD), and cognitive function using the Saint Louis University Mental Status (SLUMS). After the CST, significant improvements were observed in QoL (p = .004), depressive symptoms (p = .002), and cognitive function (p < .001), with small effect sizes. Additionally, a significant interaction between sex and dementia diagnosis status was found in predicting cognitive changes, suggesting that the relationship between dementia diagnosis and cognitive improvement differs by sex. No between-group differences were found for QoL or depression. Findings support CST as a multidimensional, non-pharmacological intervention that improves cognitive, psychological, and social outcomes. Although effects were small, consistent improvements are clinically meaningful given the progressive nature of dementia. This study extends existing literature by demonstrating CST’s effectiveness in a community-based setting and reinforces its alignment with occupational therapy’s emphasis on participation and holistic care. Results highlight the need for early intervention and expanded access to CST programs to enhance quality of life in this population.

Transboundary Groundwater Flow Between Niger And Nigeria In The Iullemeden Aquifer System, Gare Ambrose-Igho

UNLV Theses, Dissertations, Professional Papers, and Capstones

Groundwater is important in regions where water resources are not abundantly distributed such as arid and semi-arid regions. In many countries in Africa, groundwater serves as the most reliable source of water supply and supports over 50% of the African population. Groundwater is stored in underground water-bearing permeable rocks, rock fractures, or unconsolidated materials known as aquifers. Groundwater can be transboundary, meaning it crosses international political boundaries between two or more sovereign states. Transboundary aquifers are prone to overexploitation that depletes the groundwater resource and can cause a lowering of the water table and possible ground subsidence. Overexploitation in transboundary …

Unknowing Sacrifices: Public Health And Radiation Illness In New Mexico And Nevada, 1940s-1960s, Beatriz Avila-Marquez

UNLV Theses, Dissertations, Professional Papers, and Capstones

The detonation of the first atomic bomb in the early morning of July 16, 1945, in New Mexico welcomed the atomic age that forever changed the world. After that day, thousands of lives were lost due to nuclear weapons, and hundreds of thousands more continued to suffer from the effects of atomic testing. The Atomic Energy Commission, fueled by the arms race of the Cold War, chose Nevada to continue the United States’ nuclear weapons testing. Knowledge of the dangers of radiation exposure, the effects of radiation, and techniques to prevent exposure are now available in part due to the …

Exploring Ai-Driven Scaffolding For Critical Questioning In Argument Evaluation, Ebenezer A. Belete

UNLV Theses, Dissertations, Professional Papers, and Capstones

The fast-paced changes caused by generative AI (GenAI) innovations call for exploring the potential benefits of GenAI in empowering 21st-century pedagogical strategies. Previous studies in the field of argumentation have shown how students can benefit from using critical questions. However, scaffolding argument evaluation through custom GenAI using critical questions has not been systematically investigated. This study involved two components: (1) designing and determining the usability of a GPT-powered conversational assistant (CQMAA Conversational Assistant) and (2) testing its impact on participants' efficacy for argument evaluation and their acceptance of GenAI as a learning tool through a pretest–posttest experiment. A convergent mixed-methods …

Criticality Safety Evaluation To Address Potential Over Conservative Restrictions In 49 Cfr Fissile Materials – Exceptions, Avian Blumhorst

UNLV Theses, Dissertations, Professional Papers, and Capstones

The U. S. Department of Transportation’s (DOT) 49 CFR 173.453 Fissile Exceptions provide a regulatory classification that helps eliminate burdensome regulatory requirements. The current fissile exceptions are based on past technical basis reviews. These reviews may be overly conservative, and the final ruling potentially applied significant administrative over-conservatism. This thesis reviewed and presents several recommendations to the fissile exception criteria, as well as 49 CFR 173.453 section’s additions.

Using Monte Carlo N-Particle (MCNP) code version 6.3.0, several infinite sea mixtures and array systems were modeled for fissile isotopes 233U and 235U. The research demonstrated that for fissile exception (a) there …

Got Sleep?: The Introduction Of Sleep Hygiene To Justice Involved Individuals, Charisma Lynn Cato

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals transitioning out of incarceration often experience challenges with sleep due to the residual effects of confinement. Although this is common among justice-involved individuals, there is limited research on how to address their sleep hygiene self-efficacy after release. Furthermore, despite the wide use of social-emotional learning (SEL) across multiple disciplines, little is known about its influence on sleep-related behavior change in re-entry populations. To address this, the Got Sleep program, designed and implemented at Hope for Prisoners (HOPE), a community site geared toward re-entry assistance, integrated occupational therapy (OT) principles and an SEL approach with practical sleep hygiene strategies to …

Developing Vocal Technique Through The Canción Ranchera In The Middle School Mariachi Classroom, Perry Chacon Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mariachi is taught in more than 500 public school programs across the United States, yet current scholarship on the mariachi voice primarily focuses on defining and analyzing performance practice, offering limited guidance for classroom instruction. This study provides a methodology for developing healthy vocal technique in the middle school mariachi classroom. Grounded in established vocal pedagogy and informed by teaching practice, this approach first builds student confidence through participation in group vocal exploration that encourages active vocal participation. Instruction progresses from foundational skill development, including aural skills, breath coordination, and healthy vocal projection, to the application of these skills through …

Stalking Victimization Risk Factors Among College-Aged Men And Women: Does Relationship Type Matter?, Nicole Cebak

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research assessing stalking—or a pattern of repeated, unwanted behaviors directed at a specific individual that causes fear, distress, or concern for their safety—has identified several factors that can increase a person’s vulnerability to this form of victimization (e.g., demographic predictors, lifestyle factors, individual characteristics) (Fissel et al., 2023; Fox et al., 2016; Reyns et al., 2016; Reyns & Scherer, 2016). However, stalking can manifest within a wide range of relational contexts, suggesting that risk factors identified for stalking victimization more broadly may be insufficient across different victim-offender relationship types (e.g., stranger, intimate partner) (Reyns et al., 2016; Strauss et al., …

Understanding Chinese Students’ Intent To Study Abroad: Case Study Of A Collaborative Chinese & U.S. University Program, Jaekeun Cho

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examined how Chinese undergraduate students enrolled in a Sino-Foreign Cooperative Program (SFCP) made decisions about studying abroad and selected a U.S. institution, with particular attention to institutions in less traditional destinations, such as Nevada. International student enrollment has become a critical strategy for U.S. higher education institutions facing declining state appropriations, demographic contraction in domestic enrollment, and increased global competition. Although China has remained the largest source of international students to the United States for decades, states such as Nevada enroll comparatively few international students and lack empirical research on recruitment pathways. This study addressed this gap by …

Relativistic Transients From Compact Objects: Radiation Processes And Geometric Effects, Connery Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Relativistic transients from compact objects probe the most extreme regimes of physics, where strong gravity, ultra-relativistic outflows, and high-energy radiation operate simultaneously; understanding the underlying radiation mechanisms and extrinsic geometric and relativistic effects is essential for interpreting observations and constraining source properties. I develop theoretical and computational frameworks to quantify how geometry and relativistic motion shape observed emission from fast radio bursts, gamma-ray bursts, and neutron star mergers. I analyze fast radio bursts from the Galactic magnetar SGR J1935+2154 and show that emission geometry strongly governs burst energetics and detection probability, and influences the link between radio and X-ray emission. …

Enhancing Accessibility And Inclusivity In The Performing Arts With Occupational Therapy Frameworks, Carmela Clarice Tabora Clave

UNLV Theses, Dissertations, Professional Papers, and Capstones

In live theater performances, there are numerous sensory demands, including unpredictable noises, lighting, crowd movement, vocalization, and transitions in and out of the theater. Teachers, support staff, and chaperones who attend these performances may face barriers in supporting their children in unfamiliar environments, and community volunteers who have never assisted during these shows may not know how to support children who need it if they have not had prior exposure to children with diverse needs. This capstone project provides families, teachers, and volunteers with pre-visit resource guides with occupational therapy perspectives on sensory processing for student matinees and sensory-inclusive performances …

Inclusiveness With Sensory Maps; Enhancing Engagement In A Children's Museum, Victoria E. Davila

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sensory processing challenges can affect a child’s ability to engage in play, especially when participating in community activities. When a child feels overwhelmed by sensory features in an environment, such as noise or bright lights in a community space, they may experience sensory overload. Caregivers often observe this behavior but may not have access to resources to help their child navigate these challenges. This capstone project aimed to implement a program development initiative at the Discovery Children’s Museum focused on developing sensory-inclusive resources for caregivers visiting the museum with a child. The role of occupational therapy in this project is …

Organizational Justice And Staff Well-Being In Probation And Parole, Deena R. Devore

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study examines how probation and parole (P&P) officers perceive fairness within their organizations and how these perceptions relate to job satisfaction, organizational commitment, and emotional exhaustion. Organizational justice research has been conducted primarily in business and policing contexts, with limited attention to whether established measurement models accurately capture fairness in community corrections. Because P&P officers operate within hybrid roles characterized by discretion, sustained supervisory relationships, and bureaucratic constraint, fairness perceptions in this setting may not align cleanly with existing dimensional frameworks.

Using survey data collected from P&P officers in a western U.S. state, this study evaluates competing measurement structures …

Functional Domains’ Ability To Predict Outcomes In Comparison To Absenteeism In A National Sample Of School Age Children, Randolph Dupont

UNLV Theses, Dissertations, Professional Papers, and Capstones

School absenteeism poses a critical challenge for educators, clinicians, and policymakers due to its strong associations with impairments across academic, social, mental health, and family domains. Traditional models conceptualize absenteeism systemically, using dimensional definitions (e.g., chronic absenteeism defined by missed days), or analytically, using categorical definitions (e.g., truancy, school refusal). Both approaches are limited in capturing the functional consequences of school attendance problems (SAPs). This study evaluated whether a functional impairment model, which emphasizes how domains of functioning are disrupted by absenteeism, provides a more accurate framework for predicting outcomes than absenteeism frequency alone. Using longitudinal data from the Adolescent …

Interpretable Deep Learning Models For Trustworthy Prediction Of Enzyme Functions, Louis Dumontet

UNLV Theses, Dissertations, Professional Papers, and Capstones

Trustworthy prediction of enzyme function from protein sequences remains a central challenge in computational biology, particularly when annotated data are limited, imbalanced, or incomplete. This dissertation develops interpretable deep learning methods for enzyme discovery and enzyme function prediction from amino acid sequences. First, it introduces PEPIC, an interpretable convolutional neural network for substrate-level prediction of hydrolytic plastic-degrading enzymes. Using curated and expanded sequence datasets, PEPIC improved predictive performance over benchmark methods, identified sequence regions aligned with catalytic and substrate-binding residues, and supported the discovery and experimental validation of a previously uncharacterized PET-degrading enzyme. Second, this dissertation investigates the integration of …

Constructing Imperial Connectivity: State Infrastructure Projects And The Imperial Gaze In Bengal Presidency, 1849-1856, Richard William Bradley Gaspers Iii

UNLV Theses, Dissertations, Professional Papers, and Capstones

The construction of roads, canals, and supporting infrastructure in British India connected urban environs of power to interior peripheral spaces. The conclusion of the Second Anglo-Sikh War in 1849 saw the East India Company stand alone as the paramount power over the Indian subcontinent. A century of conquest gave way to a century of internal management. This shifted the state’s ‘gaze’ inward. Public infrastructure construction skyrocketed after 1849, transforming the role of the colonial state as it built roads, canals, bridges, courthouses, police stations, and jails on an unprecedented scale. This thesis will explore how these physical constructs bolstered connectivity, …

The Lotus Project: An Occupation-Based Online Module To Support Healthy Matrescence, Virginia Genato

UNLV Theses, Dissertations, Professional Papers, and Capstones

Becoming a mother is a meaningful life event that occurs amid complex physical, psychological, and social changes. During this period, individuals undergo an occupational role transition as they assume new caregiver responsibilities while navigating contextual demands. The ease of this transition influences overall maternal adjustment. The dominant sociocultural model of intensive mothering promotes child-centered caregiving, often at the expense of maternal well-being and adjustment. Efforts to meet these expectations may disrupt an individual’s transition into motherhood and place them at risk for developing postpartum mental health challenges.

The concept of matrescence provides a developmental framework that views motherhood as an …

Promoting Classroom Management Through Elementary Teacher Education On Movement-Based Social-Emotional Learning, Daija Renee Georgette

UNLV Theses, Dissertations, Professional Papers, and Capstones

This doctoral capstone project addressed a knowledge gap among K–5 th–grade teachers at Cornerstone Christian Academy (CCA) regarding the purpose, benefits, and educational value of movement-based brain breaks. Although CCA currently incorporates social–emotional learning (SEL) frameworks such as the Zones of Regulation, teachers have received limited training on how structured movement opportunities can enhance student engagement, attention, and regulation. This program aimed to strengthen teachers’ understanding and confidence by providing a series of evidence-informed workshops that explored the connections among movement, self-regulation, and classroom management.

The project consisted of orientation, teacher recruitment, needs assessment, workshop development, and program delivery over …

Establishing A Comprehensive Framework For Sfrt Lattice Treatments: Optimization, Planning, And Clinical Evaluation, Gregory M. Gill

UNLV Theses, Dissertations, Professional Papers, and Capstones

Spatially fractionated radiation therapy (SFRT) using lattice radiotherapy (LRT) has emerged as a promising treatment technique for bulky, nonresectable tumors by delivering spatially heterogeneous dose distributions consisting of high-dose vertices embedded within lower-dose regions. Although early clinical experiences have demonstrated potential therapeutic benefit, widespread clinical implementation of LRT remains limited due to the absence of standardized treatment planning workflows, consistent optimization strategies, and clearly defined evaluation metrics for heterogeneous dose distributions. The objective of this study is to develop and evaluate a structured framework to support efficient, reproducible, and safe clinical implementation of LRT.

To address these challenges, a comprehensive …

Goals, Properly Technical: Special Education Teachers Using Chatgpt To Develop Individualized Student Goals, Travis Hammond

UNLV Theses, Dissertations, Professional Papers, and Capstones

Educators’ responsibilities extend well beyond instruction to include administrative duties such as grading, maintaining records, and documenting student behavior, as well as ongoing meetings and professional development requirements (Billingsley et al., 2019; Darling-Hammond et al., 2017). These demands can create a disconnect between role expectations and daily realities (Brunsting et al., 2023). Special education teachers (SETs) face these same responsibilities alongside additional paperwork requirements, which may account for up to 20% of their workday (Carlson et al., 2002; Suter & Giangreco, 2009; Vannest et al., 2011). A central task is the development of Individualized Education Programs (IEPs), including measurable annual …

"Home Means Nevada": Latinx Belonging In A New Destination, Maria G. Hermosillo

UNLV Theses, Dissertations, Professional Papers, and Capstones

This project examines how Latinx individuals construct meanings of home and belonging in a Southern Nevada micropolitan city. Nevada is considered a new “Hispanic settlement state” and “New Immigrant Destination” as the state has experienced significant Latinx population growth since the 1990s. This research addresses an empirical gap by centering Nevada in understanding Latinxs lived experiences through the taken-for-granted concept of “home” and a theoretical gap by advancing New Destinations research where moral order, economy, and region influence ethnic incorporation.

Drawing on 32 in-depth semi-structured interviews with current and former Latinx residents and supplemented by participant observation, the study analyzes …

The Effect Of Dialogic Reading With An Adapted Reader On Narrative Reading Comprehension Of High School Students With Autism Spectrum Disorder, Ramella Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Reading comprehension is essential for accessing grade-level content; however, students with autism spectrum disorder (ASD) often demonstrate narrative comprehension difficulties related to language inferencing and self-regulation (Constable, 2013; Duke & Cartwright, 2021). Dialogic reading is an evidence-based shared reading practice that uses systematic prompts and contingent consequences to strengthen verbal behavior (Whitehurst et al., 1988; IES, 2007). Despite demonstrated effectiveness with young children with ASD, experimental research on dialogic reading with secondary school-aged students, particularly those requiring adapted instructional materials, remains limited (Hudson & Test, 2011; Spooner et al., 2012). The purpose of this study was to evaluate the effects …

Prepulse Inhibition And Emotion: A Systematic Review, Jennifer U. Le

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prepulse inhibition is a neurological pre-conscious sensorimotor gating mechanism by which a softer auditory sound (or prepulse) preceding a startle probe (or pulse) and subsequently reduce the magnitude of the startle blink reflex. Prepulse inhibition is deficient in many psychological disorders where emotion is a central component; however, emotion has been scarcely examined with prepulse inhibition in human studies. The current study is a systematic review that examines three databases (APA PSYCInfo, Pub Med, and CINAHL) to examine how state and trait emotion (such as happiness, sadness, anger, disgust) is related to prepulse inhibition within human subjects. The initial search …

Impairment And Disability In Mesoamerica: Bioarchaeological Evaluation And Interpretation Of The Maya Of Palenque, Dayanira Lopez

UNLV Theses, Dissertations, Professional Papers, and Capstones

The application of disability theory to the past is of growing interest among bioarchaeologists, both nationally and internationally. However, its application poses greater challenges when considering ancient contexts, such as Mesoamerica. Nonetheless, engagement with disability studies has led to the development of various theoretical frameworks in bioarchaeology, including dis/ability. This model views physical impairment as a fluid state that may exhibit adaptability and resilience rather than a biological deficit. Importantly, it views ability on a spectrum and does not make assumptions about social and cultural perceptions of ability where there is a lack of contextual data. Thus, it is a …

Protest Policing And Legitimacy: A Comparative Analysis Of Myanmar And The United States, Khaing Sandee Lynn

UNLV Theses, Dissertations, Professional Papers, and Capstones

Political protests garner immense attention during academic, socio-political, and policy discourse discussions. More specifically, the manner in which government, police, and protestors interact during protest events is heavily observed and debated. Research shows that legitimacy is established when power-holders act in accordance with legal frameworks and various political and institutional norms. With focus on the intersection of legitimacy and protest policing, the current study aims to explore how political, legal, and institutional legitimacy influence police compliance with state and institutional directives, and protestor compliance with police directives in two distinct sociopolitical contexts.

For this purpose, qualitative data was collected through …
