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 …

Addressing Sexual Health For Older Veterans By Healthcare Providers: A Mixed Method Study, Andrew James White

UNLV Theses, Dissertations, Professional Papers, and Capstones

Healthcare Provider Trust As A Predictor Of Covid-19 Vaccine Hesitancy Among Nevada Residents, Joanna Joseph

UNLV Theses, Dissertations, Professional Papers, and Capstones

Trust in healthcare providers is one of the strongest predictors of vaccine hesitancy in the literature, yet it has not been examined as an independent predictor of COVID-19 vaccine hesitancy in Nevada. Nevada ranks last nationally in healthcare providers per capita and is among the lowest in immunization coverage for both adults and children. The COVID-19 pandemic exacerbated negative vaccine attitudes, and vaccine hesitancy continues to be a central public health issue. Prior Nevada analyses identified vaccine hesitancy across racial, political, educational, and economic groups but did not assess the role of provider trust in vaccine hesitancy. This cross-sectional study …

The Origins Of Chondrite Families, Isabelle M. Perron

UNLV Theses, Dissertations, Professional Papers, and Capstones

Chondrites, a type of primitive asteroid, are thought to have formed from dust and gas early in the life of our Solar System. These chondrites have remained unchanged since their formation, avoiding being melted or differentiated like other rocky bodies have. Due to this unique characteristic, chondrites can give us useful insight into how asteroids, planetesimals, and even the terrestrial planets formed. In order to study chondrites and their formation, I used code developed by Li et al. (2020), which utilizes thermodynamic code GRAINS (Petaev 2009), to see what conditions the chondrites may have originated from. GRAINS uses a variety …

Preservation Of Sedimentary Rubidium Isotopic Signatures In Subduction Zones: Insights From The Schistes Lustrés Hp-Uhp Metasediments, Western Alps, Mary Clarich

UNLV Theses, Dissertations, Professional Papers, and Capstones

When oceanic plates bend and sink into the mantle at subduction zones, they carry sediments from the surface down into the mantle. The recycled sediments contain elements, that are depleted in the mantle, thereby influencing the composition of the mantle wedge and the formation of arc magmas, which are the building blocks of juvenile continental crust. However, it remains poorly constrained how much these elements, particularly fluid-mobile elements such as rubidium (Rb), are lost into fluids during metamorphic dehydration, and how much is transported to sub-arc depths where arc magmas are generated. Rubidium in subducting sediments is mainly hosted in …

Correlation Between Maxillary Transverse Width, Alveolar Housing Width And Palatal Bone Thickness: A Cbct Retrospective Study, Eric G. Hollensbe

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background:

Accurate assessment of transverse maxillary dimensions and surrounding bone morphology is critical for safe orthodontic treatment planning. Orthodontic expansion should remain within the biological limits of the alveolar housing and palatal bone to prevent adverse periodontal outcomes, including dehiscence, fenestration, and gingival recession. Standard diagnostic methods, such as dental casts and two-dimensional radiographs, offer limited information about the three-dimensional anatomy that restricts orthodontic tooth movement. Cone-beam computed tomography (CBCT) provides detailed evaluation of skeletal dimensions and cortical bone boundaries. This study aimed to examine the relationships among maxillary transverse width, alveolar housing thickness, and palatal thickness using CBCT imaging. …

Youth sport has been highly researched, exploring both positive and negative health impacts (Adetunji & Akendutire, 2017; Brengtsson et al., 2025; Conway, 2024; Hoffman et al., 2022). Despite the high prevalence of youth sport participation, and variability of health-related outcomes, there has been no research regarding the impact youth sport participation has on occupational balance, an occupational therapy concept that has been linked with overall health and well-being (Park et al., 2021). A mixed-methods, cross-sectional survey study was used to gain better insights into the impact youth sport participation may have on occupational balance. A sample size of 466 Nevada …

Harnessing Backcasting To Identify Drivers Of Critical Warming At Hoover Dam Using Hydrodynamic And Machine Learning Models, Eunice Ledres

UNLV Theses, Dissertations, Professional Papers, and Capstones

Elevated water temperatures can pose a significant threat to dam infrastructure, potentially damaging turbines, overheating internal components, and forcing generator shutdowns. This study uses a backcasting framework to evaluate how future scenarios may result in elevated water temperatures. Backcasting defines undesirable outcomes and works backward to identify the conditions that lead to them. The developed backcasting framework integrates 3D physics-based simulations with a Long-Short Term Memory (LSTM)surrogate model and SHapely Additive exPlanations (SHAP) interpretation. The combination captures temporal water temperature dynamics and quantifies the contributions of different drivers to elevated water temperature releases. As proof of concept, these methods are …

Constructing A Laser Stabilization System For Frequency Metrology, Stephanie Letourneau

UNLV Theses, Dissertations, Professional Papers, and Capstones

Frequency metrology and quantum control, which uses light as a tool for measurement and manipulation, relies on spectrally narrow, stable lasers. Often thought of as being perfectly monochromatic and coherent, in reality, the free-running instantaneous linewidth of lasers can be on the order of hundreds of kHz in the millisecond time-frame and drift on the order of tens of MHz over hours. To correct for these instabilities in real-time, a variety of laser stabilization methods have been implemented, including the Pound-Drever-Hall (PDH) method, saturation absorption spectroscopy (SAS), and dichroic atomic vapor laser locking (DAVLL). All of these methods rely on …

Beyond Additive Risk: Longitudinal Associations Between Discrimination And Positive Affect Development Among Adolescents With Single And Multiple Marginalized Identities, Vanni Jefferson V. Arcaina

UNLV Theses, Dissertations, Professional Papers, and Capstones

Adolescents with marginalized identities often face chronic exposure to discrimination, a social stressor linked to a range of negative mental health outcomes. While much of the existing literature focuses on internalizing symptoms, fewer studies have explored how discrimination may disrupt the development of positive affect (POA), which is a core dimension of emotional well-being linked to resilience, identity formation, and long-term health. The present study examined how overall, race/ethnicity-based, and sexual minority (SM)-based discrimination affects longitudinal patterns of POA among adolescents with single or multiple marginalized identities. Drawing on four waves of data from the Adolescent Brain Cognitive Development Study, …

Mapping Climatic And Environmental Determinants Of Parasitic Helminth Prevalence In Southeast Asia, Angelica Avisado

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate change is reshaping environmental conditions across Southeast Asia (SEA) through rising temperatures, altered precipitation patterns, and increased droughts. These changes alter transmission dynamics of neglected tropical diseases (NTDs) by shifting spatial distribution, increasing larval development rates, faster pathogen growth development, and increasing transmission rates. NTDs are a group of preventable and treatable infections that disproportionately affect more than 1 billion people globally, specifically in tropical and subtropical regions. A subgroup of NTDs, parasitic helminth infections (PHIs) - particularly schistosomiasis, soil-transmitted helminths, and lymphatic filariasis remains a public health concern in the Southeast Asian region. PHIs and their ecological responses …
