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).

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 …

Exact Solution Of Steady Seepage In An Asymmetrical Domain Underneath A Cofferdam, Tan Nguyen

UNLV Theses, Dissertations, Professional Papers, and Capstones

For decades, the evaluation of steady state seepage beneath asymmetrical cofferdams has relied on numerical methods, such as Finite Element Methods (FEM), Finite Difference Method (FDM), Finite Volume Method (FVM), Mesh Reduction Method (MRM), Meshless Method (MM), Boundary Element Method (BEM), or geometric idealizations, most notably Griffiths' vertical Method of Fragments assumption. While exact closed form solutions via Schwarz-Christoffel (SC) conformal mapping have been well established for symmetrical geometries (Banerjee and Muleshkov), the generalized asymmetrical case has historically remained an intractable mathematical frontier. The primary barrier to an exact analytical solution has been the "crowding problem," a numerical phenomenon where …

“I Just Kept Showing Up”: On Institutional Actors’ Motivations, Change Work, And Homeplaces At Desert Rose University In Support Of Undocumented Students, Vanessa Núñez

UNLV Theses, Dissertations, Professional Papers, and Capstones

My dissertation examines the roles that faculty and staff play in (re)shaping institutional policies and procedures to support undocumented students. While access to higher education has been examined through various lenses, we know very little about the “institutional activists” who advocate for undocumented student support in a bounded system like a college campus. The extant literature on faculty support of undocumented students focuses on the ways they create a sense of belonging and validation through mentorship and encouragement (Pérez-Huber, 2010; Gámez, Lopez, and Overton, 2017). My research suggests that while undocu student activists are the driving force behind change at …

Psychological Impact Of Nexus Program On Persons Living With Mild Dementia, Kaleigh Gailynn Quinlan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Dementia is a global health concern due to the rapidly growing aging population (WHO, 2023). A wealth of evidence exists to support the notion that lifestyle interventions not only slow cognitive decline but improve cognition (Ngandu et al., 2015; Rosenberg et al.., 2018; Meng et al., 2022). However, there is a distinct lack of qualitative evidence examining the experience of being in a lifestyle redesign program. Lifestyle interventions require a large overhaul of an individual’s habits and performance patterns, and as such, there must be a subjective experience attached. Methodology: Through convenience sampling of the residents participating in the …
