An Examination Of The Association Of Religiosity, Purity Culture, And Religious Trauma With Symptoms Of Depression And Anxiety, Kaelyn R. Griffin

UNLV Theses, Dissertations, Professional Papers, and Capstones

While no consistent definition yet exists for religious trauma, religious abuse is typically defined as a misuse of authority by a spiritual leader to coerce, control, or exploit those under their leadership, which may in turn lead to the experience of religious trauma. Numerous studies suggest that experiencing abuse within a religious environment is a both global phenomenon and common experience. The impact of religious abuse has recently gained greater media attention, specifically related to the social and psychological impact of leaving high-cost religious groups (i.e., those with rigid rules or groups from which departure leads to isolation and rejection …

Simulating Radial Ring Structure With An Ambipolar Elsasser (Am) Bump In Non-Ideal Magnetohydrodynamics Of Protoplanetary Disks, Aleksey S. Mohov

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rings are one of the most ubiquitous substructures observed in protoplanetary disks. They are known to be a robust site for planetesimal formation; thus we look for mechanisms that can originate stable rings. From chemical modelling of snow lines, we expect a bump in the Ambipolar Diffusion (AD) Elssaser number (Am) in the radial direction. We use the Athena++ code to model the non-ideal Magentohydrodynamics (MHD) behavior of an Am bump. We explore a parameter space of Gaussian bumps with Am = 5, 1, 0.5 peak strength and σ = 0.25, 1, 5. The Gaussian profile is inserted into the …

Characterization Of Hematite Coated Bedrock Fault Scarps In The Northern Colorado River Extensional Corridor Near Lake Mead, Nevada, Molly E. Pickerel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fault mirrors are reflective, thin, typically <1 mm thick, fault slip surfaces in exhumed fault zones that can provide a record of thermal, chemical, and rheological changes to fault materials during deformation. This study investigates a series of hematite coated fault mirrors along bedrock fault scarps in Miocene volcanic rocks near Lake Mead, Nevada. The studied faults are located in a structurally complex area that includes NE-SW trending left-lateral strike-slip faults of the Lake Mead fault system, NW-SE right-lateral strike-slip faults of the Las Vegas Shear Zone, and N-S striking extensional faults of the Northern Colorado River Extensional Corridor.New zircon U-Pb ages from fault scarp host rocks 21-BC-03 and 21-BC-05 are and 13.86 ± 0.27 Ma and 12.90 ± 0.31 Ma (2σ standard error), respectively. New apatite (U-Th)/He dates range from 5.64 ± 0.46 Ma to 12.4 ± 0.36 Ma (2σ standard error) and are interpreted to be partially reset after eruption due to reheating. Inverse thermal history modeling in HeFTy of apatite He dates indicates a thermal history of reheating to ~65 °C which is interpreted as shallow burial around ~11 - 5 Ma followed by cooling to the surface, interpreted as exhumation between ~4.5 - 2 Ma. The zircon U-Pb ages, apatite He dates, and inverse thermal history models indicate the fault host rocks were erupted to the surface and stayed within the upper ~2 km of the crust since the Miocene. Nearly vertical fault scarps that host the fault mirror surfaces exhibit two sets of slickenlines, indicating oblique and strike-slip motion, with different orientations indicating that there have been multiple episodes of deformation along the surfaces. Three of the five studied fault scarps have E-W orientations, and one scarp is NW-SE, and one is NE-SW striking. The studied faults are interpreted to have been active during deformation associated with the Lake Mead Fault System and the Las Vegas Valley Shear Zone at 13 – 9 Ma and record both strike slip and oblique slip events in the complex strain field during this time. Micro-nano scale texture and grain morphology analysis of the hematite fault mirror volumes shows extreme strain localization along the fault mirror surface. Some fault mirrors exhibit multiple domains separated by discrete slip surfaces. Comminution and cataclasis appear to be the dominant deformation mechanisms in the fault mirror volume. Hematite textures and morphologies are consistent with observations from other fault systems that are interpreted to record aseismic to sub-seismic slip rates, and relatively low coseismic temperature rise. Fluid injection veins and post-deformation FeO mineralization in fractures are interpreted as evidence of high fluid pressures during slip and fluid circulation postdeformation. The new geochronologic and microstructural data inform on the processes operating along discrete fault surfaces in the shallow crust since the Miocene in the Lake Mead region.

High Clearance Collision-Free Paths, Barun Thapa

UNLV Theses, Dissertations, Professional Papers, and Capstones

Path Planning is one of the widely investigated research areas in computational geometry and robotics. Given a set of polygonal obstacles inside a rectangular box, and start & goal points, the path planning problem is to construct a collision-free path connecting the start point to the goal point. We review existing well known algorithms for solving the path planning problem. We propose new approaches for constructing a collision-free path with high clearance from obstacles. The main idea of the proposed algorithm is the appropriate generation free-region nodes which can be processed to construct high clearance paths. Neighbors of free-region nodes …

Faculty, Staff and Student Publications

Hypoplastic left heart syndrome (HLHS) is a congenital diagnosis that necessitates immediate intervention at the beginning of life to ensure survival past infancy and to optimize left-side cardiac function. Often, these required procedures can lead to deleterious side effects and resultant complications. In this case report, we present a 15-month-old patient with HLHS who underwent multiple procedures, including two aortic arch surgeries. After the interventions, the patient experienced left main pulmonary bronchus compression along with pulmonary artery stenosis. In this case, we outline an approach to performing vascular dilation without compromise of airway patency.

BACKGROUND: Mitral valve (MV) elongation is a primary hypertrophic cardiomyopathy (HCM) phenotype and contributes to obstruction. The residual MV leaflet that protrudes past the coaptation point is especially susceptible to flow-drag and systolic anterior motion. Histopathological features of MVs in obstructive hypertrophic cardiomyopathy (OHCM), and of residual leaflets specifically, are unknown.

OBJECTIVES: The purpose of this study was to characterize gross, structural, and cellular histopathologic features of MV residual leaflets in OHCM. On a cellular-level, we assessed for developmental dysregulation of epicardium-derived cell (EPDC) differentiation, adaptive endocardial-to-mesenchymal transition and valvular interstitial cell proliferation, and genetically-driven persistence of cardiomyocytes in the …

Faculty, Staff and Student Publications

Solid oral medications are preferred over intravenous or liquid formulations; however, difficulty swallowing solid medication remains a common barrier to adherence. Previous reviews have demonstrated limited evidence on interventions to improve solid medication swallowing abilities. PubMed, Medline (OVID), CINAHL, Scopus, and Web of Science databases were searched for interventions to improve the pediatric population's ability to swallow solid medications. We included studies in English published after the latest review, from January 2014 through April 2022, with pediatric patients not having comorbid conditions affecting swallowing ability. The authors independently reviewed each study's sampling strategy, study design, and the strength of outcome …

Impostor Phenomenon, College-Going Knowledge, And Staff Expectations: Ramifications On First Time In College Students Enrollment, Julia A. Vickery

Electronic Theses and Dissertations

A lack of technically trained, skilled, and educated workforce has become a critical issue in Texas. Furthermore, an educated workforce improves communities and individuals with economic, health, and personal benefits. Community colleges not only provide open-access admissions and low-cost tuition but are specifically aligned with educating the technical and industrial skilled workforce. Although a post-high school education has never been more accessible or necessary for obtaining high-earning jobs, post-high school college enrollment is declining, and conventional reform strategies do not appear to be effecting change. Graduating high school students aspire to attend postsecondary training by applying and being accepted but …

Evaluating The Efficacy Of The Christian Reformational Transcendental Model Of Art Criticism As A Literary Theory Through Albert Camus’S The Stranger, Elizabeth Miller

Electronic Theses and Dissertations

The subfield of art criticism and theory within Christian reformational philosophy, a descendent of the neo-Calvinist theology developed through the work of Dutch Reformer Abraham Kuyper and others, is becoming increasingly diverse. Recently, scholars such as Leland Ryken, Glenda Faye Mathes, and Philip Graham Ryken have built upon twentieth-century theologian Francis Schaeffer’s worldview approach by popularizing a transcendental model of art criticism, an approach that applies the transcendentals of truth, goodness, and beauty to works of art. However, the transcendentals, while widely discussed in the fields of philosophy, theology, and, to a lesser extent, art theory, have not been explicitly …

Forming And Maintaining Intimate Friendships As A Twentysomething, Molly S. Burke

Electronic Theses and Dissertations

Emerging adulthood is a life stage of great change, and often instability in relationships and attachment (Demir et al., 2015; Lane et al., 2017; Shulman & Connolly, 2013). Intimate friendships can be a moderating factor and assistance in gaining stability and increasing life satisfaction (Demir, 2021; Demir et al., 2015; Sanchez et al., 2020). This study used grounded theory methodology (Creswell & Poth, 2018) to develop a model of the process which Twentysomethings undergo while forming and maintaining intimate, or best, friendships. Through interviews with best friend pairs, this study found three main phases of the best friend process: forming …

Attitudes Towards Mental Health, Spiritual Seeking, And Well-Being, David Mitchell

Electronic Theses and Dissertations

Religion plays a crucial role in many peoples’ lives, shaping the way they interact with the world and react to stressors. The Relational Spirituality Model (Sandage & Shults, 2007) posits that individuals’ relationship with God resembles humans’ relationships with one another. That is, relationships consist of intimacy and closeness as well as independence and time away from each other, otherwise known as dwelling and seeking. Previous literature has analyzed the relationship between spiritual coping and well-being, yet none have analyzed the relationship between spiritual seeking and overall well-being using attitudes towards mental health as a moderator. Participants were 84 undergraduate …

The Medicine Of Memes: An Exploration Of Humor Styles, Memes, And Dark Humor, Theodor Napp

Electronic Theses and Dissertations

The usage of humor as a coping strategy is one that has been well-studied in the realm of psychology (Abel, 2002). However, research into the usage of dark humor as a coping mechanism, as well as dark humor expressed in memes, is not nearly as well-studied. This study (N = 50) replicated previous findings on humor and personality and expanded the research on self-directed humor and dark humor by comparing it to humor styles outlined by Martin et al. (2003) and Tsukawaki and Imura (2020). Replication results were mixed, with some findings supporting previous research between the Big Five personality …
