Comparative Study Of Vocal Pedagogy Systems In South Korea And The United States: Developmental Strategies For Classical Voice Education In South Korea, Dongmin Byeon

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation presents a comparative study of vocal pedagogy systems in South Korea and the United States, with the aim of identifying deficiencies in Korean higher education and proposing strategies for reform. While South Korean university voice programs are deeply rooted in the traditional master–apprentice model and rely heavily on anecdotal teaching methods, U.S. institutions have developed structured, evidence-based pedagogical frameworks informed by anatomy, physiology, acoustics, and voice science. This research explores the historical evolution of vocal pedagogy in both countries, highlighting how traditional practices in Korea, though culturally significant, have not sufficiently adapted to contemporary scientific standards.

The Maroons: The First Black Nationalists Of The Americas, Marquise K. Camp

UNLV Theses, Dissertations, Professional Papers, and Capstones

Maroon communities are seldom discussed in academic discussions about Black nationalism. This suggests that the goals and achievements of the Maroons differed from those of Black nationalists, and that there are no significant historical links between the two. This project argues that Black nationalists and the Maroons are closely related, not only because of their shared roots in the African diaspora but also because they both sought independence and self-governance for Black people. The aims of Black nationalists like Marcus Garvey and Malcolm X closely resemble those of the Maroons. By examining the Maroons alongside Black nationalism, one can gain …

Creando Conexiones Verdaderas?: Examining Latinx Families’ Lived Experiences With Family-School Partnerships, Jacqueline M. Eddy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Family-school partnerships are essential for a child’s academic and social-emotional well-being in schools. These partnerships thrive when families and school personnel cultivate trusting, communicative, and cooperative relationships. However, families from minoritized communities, such as those from Latinx backgrounds, may encounter challenges that prevent them from forming strong, meaningful relationships with teachers and administrators. This qualitative dissertation study was grounded in a social constructivist paradigm and a phenomenological tradition. The purpose of this study was to understand the lived experiences of Latinx families as they navigate relational aspects of family-school partnerships in their children’s schools. Using semi-structured interviews, four participants were …

Towards Spatial Inversion Of Aerial Gamma-Ray Survey Data For Measurement Of Naturally Occurring Radioactivity, Daniel A. Haber

UNLV Theses, Dissertations, Professional Papers, and Capstones

Aerial gamma-ray surveying (AGRS) is used in geologic and environmental contexts to provide data on the surface spatial distribution of naturally occurring radioactive material (NORM) or other gamma-ray-emitting isotopes. The standard data reduction workflow for AGRS data involves a process whereby pointwise gamma-ray spectral data are denoised, corrected for numerous sources of background radiation and aircraft height, and are finally converted to physical values by empirical conversion factors. The reduced pointwise data are then typically spatially interpolated to form a continuous surface map.

This dissertation introduces and explores a novel spatial inversion method for reduced AGRS data that considers aircraft …

A Case Study Of The Implementation Of Nevada’S Program To Reduce Recidivism Of The State’S Female Prison Population, Lisa C. Levine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Success in public administration is often defined by long-term goals that demonstrate how effective a program or policy is. These long-term goals can take years to measure leading to investment doubts, shifting stakeholder goals, and the sunsetting of programs. There is a need to better understand how short-term and intermediate outcomes of a program can be used to measure success and the role goal orientation of stakeholders play in the implementation. Prison education programming exemplifies this problem as reducing recidivism, a leading goal for these types of programs, take a lifetime to prove. This study examines a female prison education …

Geometric And Proximity Based Substrate Targeting By Cullin-Ring Ligases, Jerry Li

UNLV Theses, Dissertations, Professional Papers, and Capstones

Homeostasis, the process of maintaining stable biochemical and biophysical conditions, is a fundamental facet of cellular viability. Biochemical homeostasis is critical to support the biological functions that sustain living organisms. Protein ubiquitylation is one of the primary cellular pathways that regulate protein homeostasis and turnover. Ubiquitylation is initiated through the conjugation of a small globular protein known as ubiquitin, onto a given substrate. There exists a myriad of cellular fates that ubiquitylated proteins may undergo, but the most widely studied pathway is protein degradation, whereby a ubiquitylated protein substrate is shunted to a large macromolecular protease known as the proteasome, …

The sample (N = 166) included women identifying as previous or current gamers. Participants were recruited from a psychology participant pool and gaming communities on Discord. We conducted a series of analyses to examine whether …

Preparing Aspiring School Administrators For Data-Informed Decision-Making, Brandi March

UNLV Theses, Dissertations, Professional Papers, and Capstones

School leaders significantly impact student outcomes based on their ability to influence school culture, climate, and student engagement. They are essential for driving school achievement and instructional improvement. As educational policies increasingly emphasize data usage, leaders must utilize various data sources in a problem-solving process known as datainformed decision-making (DIDM) to effectively guide their school improvement plans. Using DIDM effectively can enhance instruction and student achievement when school administrators and teachers have access to quality training that builds a strong foundation in data literacy skills. It is critical for administrators to provide high-quality professional development for teachers on DIDM to …

A Mixed Methods Study Of Teacher Job Satisfaction And Principal Support In Private Jewish Day Schools Through The Lens Of Self-Determination Theory, Abigail E. Moyal

UNLV Theses, Dissertations, Professional Papers, and Capstones

This mixed methods study investigated how principal support influences teacher job satisfaction in private Jewish day schools through the lens of Self-Determination Theory (SDT). SDT asserts that motivation and well-being depend on the fulfillment of three basic psychological needs: autonomy, competence, and relatedness. Using an explanatory sequential design, quantitative data were first collected from 68 teachers across five Jewish day schools in the Southwestern United States using the Teaching and Learning Survey (TALIS) Teacher Job Satisfaction Scale (TJSS) and the Principal Support Scale (PSS). Results showed moderate to high satisfaction levels and a strong positive correlation between principal support and …

Characterization Of The Electronic Structure Of Metal–Organic Framework Mil-125 And Its Derivatives Using Soft X-Ray Spectroscopies, Jennifer Alexia Napoles

UNLV Theses, Dissertations, Professional Papers, and Capstones

Metal–organic frameworks (MOFs) are highly porous, three-dimensional networks composed of coordinated metal clusters and organic ligand subunits. While tens of thousands of MOFs have been synthesized, the Ti(IV)-based MOF MIL-125 has garnered scientific interest due to the observed changes to its optical and photocatalytic properties upon chemical modification. For example, upon UV irradiation in the presence of an alcohol, MIL-125 undergoes a photochromic color change to a photodoped state that has been associated with the storage of charge in the form of Ti(III) sites. Another example is exemplified by the amine group functionalization of the 1,4-benzenedicarboxylate (BDC) linker of MIL-125 …

Integrating Post-Quantum Cryptography Into A Cdn-Style Pki: Tls And Quic Performance Across Pqc Suites, Katrina Mary Parsom

UNLV Theses, Dissertations, Professional Papers, and Capstones

Post-quantum cryptography (PQC) adds larger certificates and extra workload to the Transport Layer Security (TLS) handshake. In order to analyze the effect of that change on content delivery, a controlled testbed with conditions replicating a Content Delivery Network (CDN) is used. The system uses a standard X.509 certificate chain over TLS 1.3. It compares RSA with classical key exchange, RSA with hybrid key encapsulation mechanism (KEM), and Module Lattice-based Digital Signature Algorithm (ML-DSA) with hybrid KEM. The test harness generates and provides certificates and establishes TLS parameters. The test harness also supports mixed web workloads and records key metrics, including …

Deciphering The Crl Code: Novel Mechanisms Of Canonical And Non-Canonical Ubiquitylation, Nicholas Wayne Purser

UNLV Theses, Dissertations, Professional Papers, and Capstones

Protein degradation is a fundamental process required for maintaining cellular homeostasis in eukaryotic organisms. In humans, distinct cell types exhibit unique proteomic landscapes that are dynamically balanced by the continual synthesis and degradation of proteins. The timely removal of damaged, misfolded, or old proteins is essential to permit new protein synthesis and to ensure proper cellular function.

Central to this regulatory network is ubiquitylation, a highly conserved posttranslational modification system that governs protein stability and function across all eukaryotic cells. Through the covalent attachment of ubiquitin molecules to protein substrates, this system modulates a broad range of biological processes, including …

Hypervigilance In Emerging Adulthood: The Impact Of Trauma, Milestone Achievement, And Minority Identity, Alexis Rice

UNLV Theses, Dissertations, Professional Papers, and Capstones

Emerging adulthood is a critical developmental period marked by identity exploration, increased autonomy, and heightened vulnerability to societal pressures. This mixed methods study examined how hypervigilance: a heightened state of alertness often associated with trauma and minority stress- varies by gender, sexual identity, racial trauma exposure, and adulthood milestone achievement among emerging adults aged 18–29. A total of 369 participants completed measures assessing hypervigilance behaviors, adulthood milestone attainment, and trauma exposure. Quantitative analyses revealed that sexual and gender minority (SGM) individuals and cisgender women reported significantly higher levels of hypervigilance compared to their counterparts. Witnessing trauma inflicted on someone of …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Being a Black Woman public school principal is an intensified, all-encompassing yet rewarding role, marked by disparities that our white counterparts are not forced to navigate. Inspired by the daily, distressed calls from novice Black Women principals seeking support in their roles and personal experience, this qualitative study employs the Sista Circle Methodology (SCM) to explore their perceptions of principal preparation programs, professional support, and persistence strategies within the first five years of appointment in a large urban school district. Framed by Black Feminist Thought (Collins, 1990), the study examines the social, gender, cultural, and experiential contexts unique to Black …

Understanding The Musical Theatre Female Mixed Belt Through The Lens Of The Operatic Tenor: A Comparative Study, Courtney Schwalbe

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since its emergence in the early 20th century, the female belt voice has become central to musical theatre, yet it still receives less systematic attention than classical singing in both scholarship and collegiate pedagogy. This document frames the contemporary female belt, especially the high or mixed belt, in dialogue with the Western operatic tenor to demystify belt production for teachers trained in classical vocal pedagogy. Drawing on historical context, voice science, and applied pedagogy, the study compares defining characteristics, vocal challenges, registration, and resonance strategies across the two traditions. Both voices extend chest-dominant qualities above the primary register transition and …

A Comparison Of Airborne Tree Pollen In The Las Vegas Valley From 2017 – 2021, Asma Tahir

UNLV Theses, Dissertations, Professional Papers, and Capstones

Airborne pollen are a predominant cause of asthma, allergic disease, and respiratory infections. The strong allergenic potential of tree pollen is of a public health concern. Several allergenic trees grow in the Mojave Desert, but not all are native to the region. Concentrations of airborne tree pollen are affected by atmospheric, environmental, ecological, and geospatial factors. Previous research has reported high tree pollen concentrations in the Las Vegas Valley, but long-term comparison studies are lacking. This study measured and compared tree pollen concentrations from five different collection stations in Las Vegas. Pollen samples collected from January 1, 2017, to December …

Neutrosophic Sets and Systems

This dissertation aimed to determine the classification of animal abuse within Ecuador by severity, context, and solution through the application of IndetermSoft and the statistical-neutrosophic C4.5 algorithm to classify the uncertainty associated with judicial and administrative efforts for animal protection for domestic dogs and cats. The approach was qualitative and documentary, analyzing judicial sentences, citizen complaints, and municipal ordinances within the three largest Ecuadorian cities of Quito, Guayaquil, and Cuenca to acquire the determination of classifications of animal abuse, subsequent sanctions, and follow-ups. A modeling of IndetermSoft ensembles assessed the indeterminacy of subsequent actions, and inputted into IndetermSoft and the …

Urban Shadows In Latin America: Detection Of Crime Hotspots Using Multivariate, Geospatial, And Neutrosophic Analytic Hierarchy Process (Nahp) Analytical Techniques, Johnny Pambabay-Calero, Sergio Bauz-Olvera, Oscar Scott-Macías, Pedro Luzuriaga Cedeño, Purificación Galindo-Villardón

Neutrosophic Sets and Systems

In recent years, Guayaquil fell prey to higher levels of organized extortion compared to territorialized criminal organizations over territory, institutional weaknesses, and socio-spatial inequalities. Thus, while extortion emerged as an increasingly specialized crime, there are limited empirical studies to evaluate the crime's spatiotemporal nature or its determinants. Therefore, this study aims to identify and characterize extortion "criminal severity zones" of Guayaquil from 2021-2024, via a novel geostatistical approach, in addition to the Neutrosophic Analytic Hierarchy Process (NAHP). By implementing Exploratory Spatial Data Analysis (ESDA), Kernel Density Estimation (KDE), dimensionality reduction techniques (PCA, MDS, and t-SNE), hierarchical clustering, and Bayesian hierarchical …

Modeling The Rehabilitation Of Offenders In Domestic Violence Using A Hybrid Neutrosophic-Logistic Approach To Reduce Recidivism, Johanna Estefanía Calle Imbaquingo, Karen Milagros Díaz Salambay, Jordy Alexis Vargas Yumbo, Kevin Christopher Carrasco Azogue, Otto F. Von Feigenblatt

Neutrosophic Sets and Systems

This dissertation seeks to determine if criminal suspension—per Article 651.3 of National Criminal Code (COIP)—for domestic violence offenders in Ecuador actually reduces recidivism through effective rehabilitation. This study is significant for comprehension of offender mentality and subsequent ability to accept criminal punishment to reduce recidivism for prolonged victim safety and better acts of authority in a country where domestic violence is still a major social concern. While the existing literature has studied aspects of restorative justice, very few articles have explored the predicating factors of recidivism and the lack of judicial observation and databases due to a neoteric nature and …

Roots Of The Human Psyche: The Spiritual Connection Of Nature With The Mind, Dania Hussain Abdulmunem, Nadia Ali Ismael

Alustath Journal for Human and Social Sciences

Seamus Justin Heaney (1939-2013) was intensely engaged in nature in a way that differed from the usual concept of nature representing beauty, love, and romance. Heaney's role in portraying nature is unique. Describing nature from a deeper perspective reveals what nature hides in terms of darkness and violence. This image encourages people to contemplate more deeply because beauty may conceal a lot of sadness and grief. The poet intends to reflect on the events of the conflicts in Ireland and around the world through nature. Just as nature conceals darkness, so does the individual conceal the inner meaning of his …

Verbs With Augmented Antonyms In The Lisan Al-Arab Dictionary, Mahmoud Alwan Mahmoud, Ali Heloo Hawas

Alustath Journal for Human and Social Sciences

It is human nature to question the underlying causes of any phenomenon, regardless of its type, and to seek to interpret it through judgments deemed logical by the researcher. Reasoning is a fundamental pillar of research methodology. Several phenomena have emerged in the Arabic language that one group of scholars considers a linguistic feature, while another views as a linguistic weakness. Among these phenomena is the concept of "contradictory verbal participles," traditionally referred to as "antonyms" (al-ʾaḍdād). These are words that convey two opposite meanings, such as "black and white" or "menstruation." Scholars have debated the existence of this phenomenon …

Replacement And Reputation, Navin Kartik, Elliot Lipnowski, Harry Pei

Cowles Foundation Discussion Papers

Does electoral replacement ensure that officeholders eventually act in voters’ interests? We study a reputational model of accountability. Voters observe incumbents’ performance and decide whether to replace them. Politicians may be “good” types who always exert effort or opportunists who may shirk. We find that good long-run outcomes are always attainable, though the mechanism and its robustness depend on economic conditions. In environments conducive to incentive provision, some equilibria feature sustained effort, yet others exhibit some long-run shirking. In the complementary case, opportunists are never fully disciplined, but selection dominates: every equilibrium eventually settles on a good politician, yielding permanent …

Patterns Of Llm Weaponization: A Comparative Analysis Of Exploitation Incidents Across Commercial Ai Systems, George Antoniou

Faculty and Staff Publications & Presentations

This comparative study examines patterns of Large Language Model (LLM) weaponization through systematic analysis of four major exploitation incidents spanning 2023-2025. While existing research focuses on isolated incidents or theoretical vulnerabilities, this study provides the first comprehensive comparative framework analyzing exploitation patterns across state-sponsored cyber-espionage (Anthropic Claude incident), academic security research (GPT-4 autonomous privilege escalation), social engineering platforms (SpearBot phishing framework), and underground criminal commoditization (WormGPT/FraudGPT ecosystem). Through comparative analysis across eight dimensions—adversary sophistication, target selection, exploitation techniques, autonomy levels, detection evasion, attribution challenges, defensive gaps, and capability democratization—this research identifies critical cross-case patterns informing defensive prioritization. Findings reveal three …

Violence Between Residents In Nursing Homes Is An Enduring Problem. The Agencies, Nursing Homes, And Residents Are Playing Hot Potato With The Responsibility, Cindy Marchionda, Rafael Escalara Montoto

Capstones

Resident-to-resident aggression in nursing homes is a persistent issue, far more common than the general public realizes. While many of these violent situations can be managed, some tragically escalate to fatal outcomes, leaving families mourning the loss of their loved ones at the hands of a facility that was meant to provide safety and care during their final years. Experts agree that this issue is largely driven by chronic understaffing and insufficient training for employees on how to manage patients with dementia and aggression issues.

Laozi’S "Daodejing": A New Translation With Environmentalist Commentary, Steve Hallett

Purdue University Press Books

Laozi’s “Daodejing”: A New Translation With Environmentalist Commentary offers a new translation and fresh interpretation of the eighty-one-verse Daodejing, one of the central texts of Eastern philosophy. Likely written during the late Zhou Dynasty between 600–400 BCE, this foundational work is generally attributed to an individual named Laozi, although it is unlikely that any such person actually existed. Here, author Steve Hallett employs contemporary poetic form when translating the document’s approximately 5,000 Chinese characters and provides short analytical essays that illuminate the verses with a specific focus on the teachings they offer about social and environmental sustainability. His examination of …
