Dysregulation Of Vitamin D Receptor And Cyp450 Metabolism Enzymes May Explain Oral Cancer Responsiveness, Dustin Hunsaker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many health benefits are associated with Vitamin D (VitD), although deficiency is associated with poor health outcomes and increased risk for cancer development. For example, many tissue specific enzymes are involved in VitD metabolism, and mutations or deletions within Vitamin D receptor (VDR) genes are known to increase cancer risk by altering their functions or bioavailability, although less is known about these phenomena in oral cancers. Using well characterized, commercially available oral cell lines (OKF4, HGF-1, SCC4, SCC9, SCC15, SCC25, CAL27), mRNA expression of P450 cytochrome VitD metabolic enzymes and receptor genes by qPCR revealed differential results. One oral cancer …

The “Asian”-Ness Of Women Influencing The Romance Plot In Contemporary Ya Literature, Janetsa Jane Keovorabouth

UNLV Theses, Dissertations, Professional Papers, and Capstones

Contemporary young adult literature (YAL) is a growing genre that features a diverse range of stories, allowing young readers to see themselves reflected in realistic stories. One of its prominent subgenres, contemporary young adult romance focuses on a modern love story between two individuals. Historically, Asian American female characters were often depicted as the “model minority” stereotype or represented as exoticized figures who held traits such as mysterious, submissive, or seductive creatures. These portrayals often treated the Asian American experience as monolithic. However, the genre now explores an intersection of identity and romance, addressing themes commonly found in contemporary realism …

“Do You Even Lift, Bro?”: Correlates Of Muscle Dysmorphia Symptomatology In Filipino Male University Students, Pamela Paula C. Pioquinto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Muscle Dysmorphia (MD) is a subtype of Body Dysmorphic Disorder (BDD) and is marked by the desire to increase muscularity and reduce body fat. MD is typically more prevalent among younger male populations, and it often drives comorbid disorders, including substance abuse, eating disorders, and social anxiety. Despite the growing literature on MD, it remains understudied in certain racial/ethnic populations, such as Filipinos. Acculturation, defined as the process in which an individual adopts, acquires, and adapts to a new cultural environment as a result of immigration, influences body image by reshaping an individual’s perceptions of beauty and muscularity standards. Guided …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The researcher conducted in-depth interviews with 25 combat-experienced Veterans of the Global War on Terror who fit an operational definition of successful resocialization. How do successfully resocialized combat Veterans compare with combat Veterans who became involved with the criminal justice system? Utilizing a snowball method to identify each participant, the most significant finding from these interviews was that two factors seem to differentiate the civilian and military group styles the most, which were the overwhelming importance of purpose and tribe in the lives of combat Veterans. This confirmed the hypothesis that the most significant difference between the civilian and military …

Associations Of The Medicaid Expansion Policy With Racial/Ethnic Disparities In Breast Cancer Screening And Treatment, James Howard Smith Ii

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Aim. This dissertation examines Medicaid expansion’s effect on breast cancer (BC) screening and treatment disparities in two Medicaid-expanding states (MES) that passed Medicaid expansion (New Jersey and Vermont) relative to two non-expansion states (NES) (Georgia and Wisconsin). It then compares the association of Medicaid expansion to other states that did not undertake this policy on various subgroups, such as minorities by race and ethnicity, income, and age groups. Black women still bear significant BC disparities due to untimely screenings, treatments, and deaths. Therefore, it is critical to investigate how socioeconomic status influences racial/ethnic disparity gaps, given that BC …

Piloting The Inclusion Of Dollar Stores In The Modified Retail Food Environment Index (Mrfei) In Urban Clark County, Nevada, Tiana T. Tu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Food insecurity is the condition of having limited or uncertain access to adequate food. It contributes to poor diet-related health outcomes which are in turn influenced by the food environment. The Centers for Disease Control and Prevention (CDC) developed the Modified Retail Food Environment Index (mRFEI) to characterize food environments by measuring the proportion of healthy and non-healthy retailers. The CDC mRFEI considers a variety of establishments but fails to include dollar stores, which contribute to the food environment by offering food and, in some cases, fresh produce. This study proposed an “expanded mRFEI” that modified the CDC mRFEI methodology …

The Roles Of Oprf In Pseudomonas Aeruginosa Biofilms, Erin K. Cassin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Many bacteria form multicellular communities known as biofilms. Biofilms contain bacterial cells and a protective extracellular biofilm matrix. This matrix contains exopolysaccharides, extracellular DNA (eDNA), membrane vesicles, and proteins. The matrix proteins are far less characterized than other extracellular biofilm components. In biofilms formed by the model organism Pseudomonas aeruginosa, the protein OprF is abundant in the cellular outer membrane and the extracellular matrix. In my dissertation research, I have presented data supporting the hypothesis that the OprF protein significantly affects P. aeruginosa biofilms. By examining various strain backgrounds and the nutrient-dependent effects of glucose and sodium chloride, I demonstrate …

This study bridges the gap between vocal performance degrees and the opera industry by identifying the vocal techniques that may improve a singer’s likelihood of acceptance into an apprentice program. To achieve this, the research draws from two primary sources: pedagogical texts and interviews with industry experts who actively teach, coach, or perform alongside apprentice artists at elite opera houses. These experts include voice teachers Darrell Babidge and Jack LiVigni, vocal coaches Beatrice Benzi and John Parr, and internationally acclaimed …

Highways To Hell: How The Intersections Of Cinema, Rock Music And The Resurgence Of Evangelicalism Influenced The 1985 Senate Hearing On Rock Music, David J. Fewell

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Senate hearing on the “Contents of Music and the Lyrics of Records, held on September 19, 1985, was as much a popular culture event as a public airing of concerns about explicit content in music. Much has been written about the significance of the Parents’ Music Resource Center (PMRC), the Senate hearing and the issues it engaged in, and how it colored conversations about censorship of the arts, the effectiveness of rating systems to police popular media and the effects of media on children’s behavior and development. The thesis will explore aspects of formative trends that influenced the PMRC’s …

The M0 cells were challenged with formalin killed P. gingivalis for 24 hours. After prolonged exposure to P. gingivalis, …

Advanced Literacies In The 21st Century: Examining A Narrative-Based Video Game As A Stealth Assessment For Comprehension, Joseph Paul Fiorentini

UNLV Theses, Dissertations, Professional Papers, and Capstones

In our technology-rich 21st Century, the need for valid, reliable, and fair literacy assessments remains pertinent to the field of education. This study defines literacy as advanced literacy where comprehension is considered a holistic product of applying acquired knowledge, skills, or abilities (KSA) to contextualized situations. Conventional assessment methods have traditionally parceled out the construct into its component parts (i.e., vocabulary, phonics, fluency, etc.) as a means of understanding the meaning making process from a traditional literacy perspective. Stealth assessments utilize the Evidence-Centered Design (ECD) framework as a robust method for assessing complex constructs holistically within technology rich environments. Adapting …

Sub Terra, Daniel J. Forest

MFA Thesis Exhibit Catalogs

Abstract

Sub Terra is an immersive exhibition that renders intangible states of mind through sculptural installation. These constructions speak to internalized angst and complexity, mirroring what is seldom looked at, witnessed, or acknowledged. Many symbolic elements are suspended from either the walls and ceiling or within constructed frames, evoking entanglement. My work is an attempt to express the emotion turmoil inherent to living in an increasingly bureaucratic society and its effect on someone with an anxiety disorder.

The fabrication entails several broad skill sets, requiring familiarity with psychology, physiology, fine woodworking, ceramics, felting, and drafting. Preliminary sketches guided construction and …

Spanish and Portuguese ETDs

This dissertation examines the interaction between liberation theology and the

dictatorships of the Southern Cone from the 1960s to the 1980s through cinematic

representation. Filmmakers from Argentina, Brazil, Chile, Paraguay, and Uruguay

depict the political upheavals of the time, including the rise of leftist movements,

military regimes, and the influence of liberation theology, a progressive religious

ideology advocating for the oppressed. The study focuses on what is defined here

as the "cinematic canon of liberation theology," a body of films and documentaries

that legitimize, contest, or obscure ideologies tied to this movement vis-à-vis the

dictatorships. These films contest the silence …

Policy Analysis Of Assessments To Award Seals Of Biliteracy In Spanish In The United States, Lisa J. Harmon-Martínez

Teacher Education, Educational Leadership & Policy ETDs

The Seal of Biliteracy (SoBL) honors high school graduates demonstrating proficiency in two or more languages, yet its policies often perpetuate inequities. Focusing on New Mexico and Spanish language assessments, I explored how the SoBL's recognition of bilingualism intersects with biases against Spanish speakers. While the SoBL aims to celebrate bilingualism, disparities arise from state-to-state variations in assessment requirements, particularly affecting Spanish-speaking students and those receiving English Language Development services. Many states rely on standardized exams that inadequately capture students’ linguistic abilities, exacerbating inequalities. Using an Open Systems policy framework and Translanguaging theory, which values students’ full linguistic repertoires, I …
