The Contribution Of Psychophysiological Stress Factors On Muscle Cramp Susceptibility, Lauren D. Levine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Exercise-associated muscle cramps (EAMCs) are painful phenomenon that involves involuntary muscle spasms occurring during physical activity or directly after. 1 The landscape of the research on EAMC etiology has expanded from focusing on a single prevailing cause (e.g., hydration status) to a more holistic approach of how numerous factors contribute to the onset of neuromuscular fatigue, and the significance of each factor in those who suffer from EAMC. Following the multifactorial theory of cramp pathophysiology, this research sought to advance the knowledge of cramp susceptibility by investigating if there is a relationship between common psychophysiological factors like high anxiety, sleep …

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 …

From Flight To Hatching: Adult Sexual Dimorphism, Life History, And Egg-Stage Ecology Of Pseudocotalpa Giulianii, Mandylene Mountain

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Nevada endemic dune beetle Pseudocotalpa giulianii is currently known only from two dune systems in Amargosa Valley, Nevada, yet much of its life cycle occurs below the sand surface and remains poorly documented. This thesis addresses key gaps in adult-stage biology and egg-stage development that are relevant to understanding reproduction, vulnerability, and habitat requirements in this dunerestricted species.

To characterize adult sexual dimorphism and life history, I quantified morphological differences between males and females and measured sex-specific adult survival under laboratory conditions relative to the aboveground flight season. Males and females overlapped broadly in external body size, but tarsal …

Shaping Narratives By Defying Math: How Black Congressional Candidates Frame Economic Issues From 2018–2022, Dante Allen Miller

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation moves the discussion of Black candidates economic policies beyond race to understand how Black candidates participate in racial capitalism. Using a mixed-methods approach, including textual analysis, and multinomial logistic regressions, I interrogate how 374 Black candidates navigate economic framing. Candidates use four distinct economic frames, three of which are rooted in neoliberalism, traditional, welfare state, progressive, and vague values. I present the findings in three papers which examine framing via textual analysis, the intra-categorical differences, and differences by congressional district demographics. In the first paper I show that Black candidates framing of economic issues reinforces racial capitalism even …

The Impact Of Language-Concordant Diagnosis Education On Discharge Readiness For Spanish-Speaking Patients, Jorge Noel Perdomo Rodriguez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Current language service practices fail to meet the needs of Spanish-speaking patients with Limited English Proficiency (LEP) resulting in decreased satisfaction with care, understanding of diagnosis education, and increased risk of post-discharge health disparities. Language-concordant care has been found to improve patient satisfaction with care and increase quality of transition from hospital to home. Research on language-concordant OT care is scarce and current studies suggest that language discordance leads to decreased quality of OT care for Spanish speakers. Problem: Language discordance leads to poor understanding of OT’s role and decreases patient-centered care for Spanish-speaking patients. Purpose: This project aimed …

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 …

Who Am I As An Elementary Cs Teacher? The Identity Development And Struggles Of Elementary Teachers As Computer Science Teachers, Burak Sahin

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study investigates how elementary teachers develop and negotiate their identities as computer science (CS) teachers within the expanding presence of CS in early K–12 education. As CS is increasingly integrated into early grades, many teachers are expected to teach it without formal preparation. It positions them to simultaneously learn, teach, and construct a professional identity in an unfamiliar domain. Using an interpretive phenomenological approach, this study examines teachers’ lived experiences of identity development by drawing on identity theory (Gee, 2000) and the performance, recognition, and competence framework (Carlone & Johnson,2007) to understand how identity is shaped through practice, institutional …

2d And 3d Insights Into The Formation And Emplacement Of Martian Meteorites, Sierra Rhaye Ramsey

UNLV Theses, Dissertations, Professional Papers, and Capstones

Martian meteorites are the only samples currently available from Mars, making their study critical for understanding martian igneous processes. Despite extensive study over the last five decades, the formation (e.g., mantle sources, crystallization pressures), emplacement (e.g., intrusive versus extrusive), and shock histories of these rocks remain uncertain due to their innate lack of geologic context and limited petrologic tools calibrated for martian conditions. This dissertation analyzes a large suite of 22 igneous martian meteorites using complementary 2D and 3D analytical methods to better constrain the magmatic, emplacement, and shock processes responsible for their formation and ejection from Mars.

An Ex Post Facto Study: The Social Validity Of Two Evidence-Based Instructional Practices, K. Ryan Wennerlind

UNLV Theses, Dissertations, Professional Papers, and Capstones

For over 15 years, the opportunity for individuals with intellectual disabilities to continue education in inclusive postsecondary education programs has steadily risen (Baker et. al, 2018). Poor employment trends for these individuals has motivated institutions to provide more educational opportunities by increasing the number of such programs. Education is consistently linked to greater employment opportunities and the potential for greater earnings as more education is achieved (BLS, 2023). Research attests this connection by studying individuals’ experiences in education after high school. In addition to greater employment opportunities, those individuals receiving postsecondary education services are also earning wages at a higher …

Vegetated Canopy Heterogeneity Footprints In The Roughness Sublayer, Giulia Salmaso, Raul Bayoan Cal, Marc Calaf

Mechanical and Materials Engineering Faculty Publications and Presentations

Turbulent flows over horizontally homogeneous rough surfaces are categorized as rough‐wall boundary layer flows, while flows over homogeneous vegetated canopies are better described through a mixing‐layer analogy. At present, numerous studies have investigated canopy density as a transition mechanism between rough‐wall and mixing‐layer‐type flows. Yet, most considered canopies have been spatially homogeneous, with few exceptions investigating agricultural arrangements. However, most vegetated canopies are not homogeneously distributed, but instead contain gaps and spatial heterogeneities of different scales. In these cases, it remains unclear which are the dominant flow traits, and how spatial heterogeneity affects them. To help overcome these knowledge gaps, …

Vietnamese American Anti-Imperialism: South Vietnamese History And Analysis Of Publications Pre-1975, Jeannie Nguyen

Master's Theses

During the Vietnam War, citizens contested US imperialism at multiple levels. In South Vietnam, citizens published newspapers and magazines to challenge their government and expose the depth of US aggression in South Vietnamese society and culture. Inside the imperial core, Black, Chicano, and Asian American activists formed solidarities to resist the war and challenge racial inequality. At the intersection of imperialism inside and outside its borders, lies a group of South Vietnamese students and scholars who became American, migrating during the war via state-structured projects. However, in response to the heightening of war and drawing inspiration from their ‘Third World’ …

Delayed Timing Of Spring Application Of Nitrogen In Corn, Elizabeth Mae Worley

Theses and Dissertations

Application timing of nitrogen (N) fertilizer within the corn growing season can be crucial to crop nutrient uptake and availability. A lack of region-specific timing recommendations may result in inefficient fertilizer use and inconsistent yield responses. The objectives of this study were to determine how late in the growing season a first and second N fertilizer application can be pushed until corn yield is impacted and investigate whether Growing Degree Days (GDDs) should be used as better estimate of timing for N application than calendar date or growth stage. First applications were able to be delayed until V4-V6 growth stages …

Quantitative geomorphic variables including slope, curvature, aspect, rugosity, geomorphons, and Bathymetric Position Index were generated from 30-meter digital elevation models and used as explanatory variables in presence-only Maximum Entropy models. Known locations of faults, pockmarks, mud volcanoes, hydrocarbon seeps, and landslides (particularly intact scarps) were used to train and validate predictive models through k-fold cross validation. Model performance was assessed using omission rates and AUC values. Results demonstrate that specific geomorphic signatures, …

Beyond English: Auditing And Mitigating Cross-Lingual Data Contamination In Multimodal Large Language Models, Pavan Dharma Adapa

Theses and Dissertations

This thesis extends data contamination auditing for multimodal large language models to multilingual settings. Using LLaVA 1.5 and a high-fidelity French parallel dataset derived from ScienceQA, the study evaluates how performance changes when identical image-question pairs are translated from English to French. The resultsshow a substantial cross-lingual performance decline and frequent flips from correct English predictions to incorrect French predictions, indicating that benchmark performance can depend heavily on memorized English-specific patterns rather than stable multimodal reasoning. To address this weakness, the thesis introduces an inference-time mitigation strategy based on perturbation ensembling and cross-lingual consistency aggregation. The proposed method reduces instance-level …
