The Yorp Effect In Reboundx, Kaelyn Clement

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Yarkovsky-O’Keefe-Radzievskii-Paddack (YORP) effect is a radiation-induced torque that can affect the spin and rotational obliquity of small bodies. It has been observed to alter the rotation rate of asteroids in the Solar System (Lowry et al. 2007; Taylor et al. 2007). Under extreme circumstances, YORP can cause a body to fragment, inducing a cascade of fissions. This effect may be important in driving the pollution of white dwarf atmospheres in conjunction with other radiative forces. I developed a YORP calculator for REBOUNDX (Tamayo et al. 2020), an extensional library to the N-body integrator REBOUND (Rein & Liu 2012). I …

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 …

Perception Of Emotions In Autism With Controlled Elicitation, Rachel E. Dewald

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research on emotion recognition in autism has traditionally relied on stimuli developed and validated exclusively with allistic populations. Whether these stimuli function equivalently for autistic individuals remains unclear, limiting the field’s ability to draw conclusions about cross-neurotype differences in emotional processing. Grounded in double empathy theory and cross-cultural research demonstrating in-group advantages in emotion recognition, this thesis investigated whether the Database of Emotional Videos from Ottawa (DEVO), a dynamic emotional elicitation database validated with allistic participants, elicits comparable emotional responses in autistic individuals. Participants (N = 116) viewed DEVO video clips and rated their emotional responses using the Multidimensional Visual …

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 …

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 …

A Modified Maximum Likelihood Estimation Algorithm For Modeling Threshold Exceedances With The Generalized Pareto Distribution, Jeffrey Harkness

UNLV Theses, Dissertations, Professional Papers, and Capstones

A modified maximum likelihood estimation (MLE) algorithm is proposed for modeling threshold exceedances with the generalized Pareto distribution (GPD). The algorithm addresses multiple issues with an approach originally published in the Journal Computational Statistics and Data Analysis (Castillo and Serra, 2015). The modified algorithm is intended to be comparatively simple to understand and implement, accurate in the handling of boundary conditions, relatively fast and reliable for most data sets, and relatively easy to transfer between computer languages by leveraging existing optimization routines.

A reproducibility study of work in recent literature published in the journal Extremes (Belzile, et al., 2023) is …

"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 …

Student-Athlete Flourishing In Intercollegiate Athletics: A Mixed Methods Study, James Hines

UNLV Theses, Dissertations, Professional Papers, and Capstones

Comprehending the complexities associated with student-athlete well-being while competing on campus is important for both institutions of higher education and the National Collegiate Athletic Association (NCAA). Studies relating to student-athlete well-being have researched many different areas such as suicide prevention (Gross et al., 2020), mental health treatments (Ryan et al.,2018), and injury recovery (Martin et al., 2021). Few studies have examined student-athlete flourishing which focuses on helping individuals thrive and reach their greatest potential. This study employs an explanatory sequential mixed method design to examine student-athlete flourishing along with factors associated with student-athlete flourishing. Survey data (N=89) provided insight on …

Expressions Of Taiwanese Cultural Identity In Piano Music: A Study Of Hsiao Tyzen’S Memories Of Home And Ma Shui-Long’S A Sketch Of The Rainy Harbor, Fang-Yu Hsu

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study investigates how Taiwanese cultural identity is expressed in the piano works of composers Hsiao Tyzen and Ma Shui-Long, focusing on Hsiao’s Memories of Home and Ma’s A Sketch of the Rainy Harbor. While both composers are pivotal figures in Taiwan’s musical history, their approaches to integrating local heritage with Western compositional techniques differ significantly. This dissertation argues that they represent two distinct creative paths: Hsiao’s model of Romantic Nationalism and Ma’s model of Modernist Synthesis.

Through historical contextualization and detailed musical analysis, this research examines the specific methods each composer employed. The findings reveal that Hsiao directly quotes …

A Tale Of Two Mammals: Tenrec Ecaudatus And Homo Sapiens, Debra Renee Kerr

UNLV Theses, Dissertations, Professional Papers, and Capstones

Most modern mammals maintain stable body temperatures (Tb) ~37ºC and high metabolic rates. Hibernators, like ground squirrels, are homeothermic during the active summer season, but are heterothermic during the hibernation season. During the hibernation season, ground squirrels follow a predictable pattern of torpor bouts interrupted by interbout arousals. Tenrecs are unusual because they are heterothermic and heterometabolic even during the active season. Previously, ground squirrel bile constituents were shown to be predictive of whether a squirrel is in the summer active or winter hibernation season. We found tenrec bile constituents were highly variable and not predictive of seasonal and metabolic …

An Optimization Method For Near-Linear Phase Analog Frequency Sampling Filter Design, Leonardo Ledesma

UNLV Theses, Dissertations, Professional Papers, and Capstones

Analog frequency sampling filters (FSFs) realize a desired frequency response by interpolating a frequency response through a set of harmonically related frequency samples from the filter’s frequency response and are magnitude and phase coefficients used in the filters transfer function. FSFs can be designed to have exact linear phase which makes the FSF attractive for many applications. A FSF’s system transfer function (STF) shows that the filter can be implemented by a series connection of a comb filter and a parallel array of resonators. However, the FSF requires that the zeros created by the comb filter cancel the imaginary axis …

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 …

This dissertation examines the historical and cultural background of pihuang, analyzes the musical language of the work, and discusses its interpretation in performance practice. It focuses especially on pentatonic materials, operatic melodic lines, rhythmic features, timbral images …

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 …
