Development And Validation Of A Pronation-Supination Testing Protocol For Rat Elbow Joint Function, Genevieve Jarrell

Mechanical Engineering and Materials Science Independent Study

Post-traumatic joint contracture (PTJC) of the elbow results in pain, stiffness, and loss of motion that can substantially impair daily function. While flexion-extension deficits in PTJC have been well characterized, the effects on pronation-supination remain poorly understood due to limited testing capability. The objective of this study was to develop and validate a method for quantifying rat elbow pronation-supination motion to better characterize elbow dysfunction. An existing load-controlled cyclic testing protocol was adapted using a rack-and-pinion system to convert linear displacement into forearm rotation, generating torque-displacement curves from which range of motion (ROM) and stiffness were evaluated. The protocol was …

Intervention Outcomes Of A Family-Based Intervention: A Case Review Of An Asian American Adolescent At Clinical High Risk For Psychosis, Monica Elizabeth Done

UNLV Theses, Dissertations, Professional Papers, and Capstones

Schizophrenia is a lifelong and debilitating condition that occurs in approximately 1% of individuals globally and includes positive, negative, disorganized, and other symptoms that interfere with functioning. The onset typically happens in adolescence, and recently, there has been an emphasis on finding individuals who are at high clinical risk for developing psychosis (CHR-P). Additionally, there has been a focus on creating intervention programs that may treat symptoms in the early phases of illness and decrease the likelihood of developing a schizophrenia spectrum and other psychotic disorders (SSD). Furthermore, there is limited research on the potential impacts of cultural identity on …

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 Phenomenological Study Of The Experiences Of Adolescents With Emotional Behavioral Disorders In High School, Melissa Lawson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Ankimedbench: Evaluating Hierarchical Medical Knowledge In Language Model Embeddings, Neel Patel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite achieving over 90% accuracy on medical benchmarks, recent studies show physicians cannot effectively leverage language models to improve clinical reasoning. Current benchmarks test isolated factual recall, but clinical practice requires hierarchical navigation through diagnostic categories—starting broad and narrowing systematically from chest pain to cardiovascular pathology to myocardial infarction to specific STEMI types. Existing evaluations cannot measure whether models preserve this taxonomic structure essential for clinical reasoning.

We introduce AnkiMedBench, built from 16,512 medical flashcards used by students preparing for licensing exams. Cards are organized across six hierarchy levels spanning 16 broad medical specialties to 672 specific diseases and conditions. …

Perceptions And Behaviors Of Female Title I Principals And Faculty Trust In The Post-Covid-19 Educational Environment, Jessica A. Robbins

UNLV Theses, Dissertations, Professional Papers, and Capstones

Faculty trust in principals is essential to a healthy school culture, yet it remains one of the most fragile and complex aspects of leadership, particularly in Title I schools (Tschannen-Moran, 2007, 2014; Tschannen-Moran et al., 2015). While trust has been widely studied, fewer investigations have focused on the specific behaviors female principals use to build trust in the post-COVID era (Berkovich, 2018; Bukko et al., 2021; Handford & Leithwood, 2013; Jeanquart-Barone, 2013; Zajda et al., 2023; Zheng et al., 2021).

“I Can Gossip With Anybody, I Can’T Chisme With Everybody”: Chisme, Gossip, And Identity In Latina-Americans, Alexa B. Romero

UNLV Theses, Dissertations, Professional Papers, and Capstones

As individuals adjust to their belonging to two distinct cultures, there are various ways of adapting to their navigation of the two cultures (Berry, 1980). The way(s) an individual chooses to adjust to their two cultures can have varying effects on identity. When directly translated, chisme (Spanish) means gossip. Although the two include overlap in function and uses, chisme offers unique purposes for the Latinx community and further, Latina-Americans (González Ybarra & Player 2024; Gutierrez, 2017; Uribe, 2025). By using the communication theory of identity (Hecht, 1993) the purpose of this thesis was to investigate the role of chisme and …

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 …

Trauma Beyond Time: Temporal Constructs In Holocaust Testimonies, Sarah Seiselmyer-Snyder

Purdue University Press Books

Trauma Beyond Time: Temporal Constructs in Holocaust Testimonies challenges our understanding of what it means to be a Holocaust survivor, arguing that the term “post-Holocaust” fundamentally misrepresents survivors’ experiences. Through careful analysis of Holocaust literature and testimony, this book reveals how trauma persists across generations, defying conventional historical timelines. For those who perished, there can be no “after” to the Holocaust—their stories were violently ended. Yet for survivors, the Holocaust didn’t simply conclude in 1945. Their experiences demonstrate how trauma continues to shape lives decades later, making “post-Holocaust” a misleading concept that fails to capture their ongoing reality. Using the …

Health Services and Informatics Research

Introduction:

Prior research links maternal smartphone use to reduced sensitivity and responsiveness to infant cues, but emerging evidence suggests that mothers' perceptions of their smartphone use - such as feelings of empowerment or distress - may also shape the quality of mother-infant interactions. This study examined how both objective and perceived smartphone use related to mother-infant interaction quality in naturalistic settings.

Method:

Participants were 147 mother-infant dyads from a longitudinal study of smartphone use and infant development. When infants were 2 months old, mothers completed 5 days of ecological momentary assessment (EMA), reporting time spent with their infant, perceived smartphone-related …

Investigation Of Mono-Allelic Rack1 Deletion Effects On Cell Growth And Pkc Mrna Expression, Ashen Quiambao

Seton Hall University Dissertations and Theses (ETDs)

The µ-opioid receptor is a primary target of clinically used opioids, and RACK1 regulates its transcription by physically interacting with MOR transcription regulator PCBP1 in the cytosol to prevent its nucleus translocation. Two mono-allelic RACK1 knockout cell lines named RACKA and RACKB were generated by the CRISPR-Cas9 technique using WT NMB neuroblastoma cells. As RACK1 also contains a PKC-binding domain, this study aims to evaluate the impacts of mono-allelic deletion on cell growth rates and PKC isoform expression. Although a slight decreased tendency of growth rate in RACKA and RACKB cells was observed when compared to that of WT NMB …

The Impact Of Youth Sports Participation On Academic Performance And Sense Of Belongingness In Middle School Students, Kevin Stahl

Seton Hall University Dissertations and Theses (ETDs)

This quantitative study explored the relationship between youth sports participation, academic achievement, and sense of belonging among middle school students. Using data from the Middle Grades Longitudinal Study of 2017–2018 (MGLS; National Center for Education Statistics [NCES], 2018), the research examined whether involvement in youth sports predicts outcomes in mathematics, reading, and students’ perceived connection to their school environment.

The findings challenged the extent to which Astin’s (1984) theory of student involvement generalizes to early adolescent populations. Although the theory proposes participation in structured activities supports both academic and social outcomes, results indicated stronger and more consistent associations between sports …
