Volunteer Experiences In Outdoor Recreation: Navigating Uncertainty And Belonging, Morgan R. Purdy

UNLV Theses, Dissertations, Professional Papers, and Capstones

Volunteers play a central role in the operation of outdoor recreation areas, yet their positions often lack formal training, clear authority, and consistent structural guidance. While organizational socialization research has focused primarily on paid employees, less is known about how volunteers in outdoor contexts navigate uncertainty and develop identity through communication. Guided by organizational socialization theory and volunteer communication scholarship, this qualitative study examines two research questions: How do outdoor recreation volunteers manage uncertainty during socialization? And how does volunteering shape their sense of identity and belonging? Drawing on 13 semi-structured interviews and prolonged ethnographic fieldwork within a public land …

Methylation-Dependent Regulatory Pathway That Governs The Stability Of The Sox Family Proteins And Related Developmental Regulators, Keshari Gayathri Rajawasam

UNLV Theses, Dissertations, Professional Papers, and Capstones

The SRY (Sex-determining Region Y) protein is a transcription factor encoded on the Y chromosome and is the key regulator responsible for initiating male sex determination in mammals. During early embryonic development, SRY activates the genetic program that leads to testis formation by promoting the expression of downstream genes involved in male gonadal differentiation. Mutations or dysregulation of SRY can lead to disorders of sex development such as male-to-female sex conversion and hermaphroditism, highlighting its critical role in sex determination.

SRY belongs to the SOX (SRY-related HMG-box) family of transcription factors, which includes the proteins SOX1, SOX2 and SOX3. These …

Fast Radio Bursts And Long Period Radio Transients: Radiation Mechanisms And Propagation Effects, Yuanhong Qu

UNLV Theses, Dissertations, Professional Papers, and Capstones

Fast Radio Bursts (FRBs) are bright radio bursts with the highest brightness temperatures in the radio sky. In this thesis, we investigate the trigger mechanisms, radiation mechanisms, and propagation effects of FRBs. Two general classes of coherent radiation mechanisms are considered in two categories: pulsar-like models invoking emission originating within the magnetar magnetosphere, and GRB-like models, which attribute the emission to relativistic magnetized shocks occurring far away from the central engine. We use the general observed properties (polarization features and spectra bandwidths) of repeating FRBs to constrain the physical conditions needed for these two mechanisms. We propose that crust quakes …

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examined the relationships among collaborative teaching practices, teacher selfefficacy, and self-regulation among 226 in-service K–12 teachers in Southern Nevada public charter schools. Teaching is a demanding profession that requires strong self-regulation (goal setting, monitoring, reflection, and adaptive strategies) and self-efficacy to sustain effective instruction, teacher well-being, and professional longevity. Collaborative teaching practices, which emphasize teamwork, shared planning, and peer support, were hypothesized to strengthen these psychological capacities within charter environments characterized by high autonomy and accountability. This research study focuses on 3 questions including demographic and situational variables that contribute to differences in teachers’ self-regulation, teachers with higher …

Is Forgetting Independent Of Learning? An Examination Of Initial Learning Across Alternative Forgetting Analyses, Rhiannon Nicole Soriano Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

A long-standing debate has reappeared regarding whether the rate of forgetting is independent or dependent upon the initial degree of learning. Interestingly, both conclusions have been supported. These diverging conclusions could be due to the analytical method and operational definition of forgetting employed: Researchers supporting independence typically measure forgetting as the number of items forgotten at a given retention interval, while those in favor of dependence typically measure forgetting as the number of items forgotten between test intervals. The current study tested whether the degree of learning affects the rate of forgetting for recognition accuracy (da) and other memory processes …

Exploring Non-Native English Learners’ Attitudes Towards Ai And Online Multimedia Persuasive Opinions And The Role Of Sentiment, Zvetomira N. Svetleff

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study and various other studies use quantitative models to identify which persuasive features predict persuasiveness. Most studies in the field do not explain why participants responded as they did nor do they focus on studying adult non-native English learners also referred to as second language (L2) English learners. Despite seemingly remarkable progress on research related to how to convey persuasive messages, there has been little work related to persuasive messaging targeted at second language learners or non-native speakers. In addition, despite the increasing reliance on AI technologies and tools in language learning within educational and work settings, there has …

Examining The Effects Of Tailored Ergonomic Interventions On Reducing Musculoskeletal Disorders For Taxi Drivers, Amal Youssouf

UNLV Theses, Dissertations, Professional Papers, and Capstones

Taxi drivers are frequently exposed to prolonged sitting, whole-body vibration, limited rest opportunities, and psychosocial stressors, placing them at increased risk for musculoskeletal disorders (MSDs). This can be mitigated with the use of ergonomics, which changes one's environment to match an individual's needs within the context and demands of the job. Although ergonomics is a recognized area of occupational therapy (OT) practice, current research is limited to office-based or computer-related settings, leaving a gap in OT-led ergonomic interventions tailored for professional drivers. This capstone project aimed to determine whether OT-based ergonomic strategies, along with an ergonomic checklist as a guideline …

Micromagnetic Simulations Of Field-Driven Antiferromagnetically Coupled Skyrmions, Aidan D. Kirk

Physics and Astronomy Honors Papers

Competing magnetic interactions can stabilize smooth magnetization textures and can be characterized by a topological winding number. A specific spin configuration/texture, spatially localized within a two-dimensional plane, is commonly known as a skyrmion. On the classical level, the significance of skyrmions for condensed matter physics and their potential for applications, ranging from spintronic devices to qubits, has been intensely investigated in recent years. This thesis focuses on antiferromagnetically (AF) coupled Neel-type magnetic skyrmions, which are comprised of two skyrmions with opposite topological charges, yielding a net topological charge of 0. This configuration results in the cancellation of their respective Magnus …

Modernidad, Heterogeneidad Y Utopía En Todas Las Sangres De José María Arguedas, Matthew J. Adams Jr

Spanish Honors Papers

This project analyzes José María Arguedas’s novel Todas las sangres (1964), focusing on the sociological and utopian dimensions that were explicitly questioned during the roundtable discussion on the novel held at the Instituto de Estudios Peruanos (IEP) on June 23, 1965. In that forum, participants offered pointed critiques of the plausibility of the social reality represented in Arguedas’s narrative. Moving beyond these objections, I argue that the literary reality Arguedas constructs—through what Antonio Cornejo-Polar has conceptualized as the “choral novel”—captures the enduring force of the colonial legacy and the historically and culturally heterogeneous condition of Peruvian society, dimensions that the …

Weighted Blankets: Implementation Of A Quality Improvement Pilot Project In The Neurosciences Intensive Care Unit, Anita Musafar

Patients within the Neurosciences ICU (NSICU) at SHC are clinically complex and uniquely vulnerable to experiencing agitation. The objectives of this initiative were to understand nurses' perceptions surrounding weighted blanket use in the critical care setting and assess whether there was a decrease in Richmond Agitation-Sedation Scale (RASS) scores with this intervention. From September 2025 to December 2025, the nurses within the NSICU implemented the use of weighted blankets for …

Accuracy Of Parameter Estimation For A Simple Gene Regulatory Network Model Is Sensitive To Network Motif, Number Of Parameters Estimated, And Magnitude And Direction Of Regulatory Relationships, Nikki C. Chun, Kam Dahlquist

Honors Thesis

A gene regulatory network (GRN) is a set of transcription factors that regulate the expression of genes encoding other transcription factors. The dynamics of a GRN explain how gene expression changes over time. GRNmap is a MATLAB software package that uses ordinary differential equations to model dynamics of small-scale GRNs. We used the program to estimate production rates, expression thresholds, and regulatory weights for each transcription factor in three related literature-derived GRNs based on yeast cold shock microarray data previously collected in the Dahlquist Lab. We noticed large differences in estimated weight values when 1-2% of the expression values were …

Reducing Maternal Morbidity In Black Women In Massachusetts, Priya Thorat

Capstones

Racial disparities in severe maternal morbidity (SMM) represent a persistent and preventable public health crisis in Massachusetts. Black women experience SMM at two to three times the rate of White women, disparities driven primarily by structural racism, fragmented perinatal care, and unaddressed social determinants of health rather than individual clinical risk. This systematic review examines the evidence supporting Community Health Worker (CHW) home visiting programs as a targeted intervention to reduce racial disparities in SMM among Black MassHealth enrollees, and evaluates the policy mechanisms necessary to sustain this intervention at scale. For this systematic review, peer-reviewed literature published between 2020 …

Acoustic To Electronic: Multidimensional Musical Explorations, Kanenar Wen

Student Theses

The music of the film was once thought to affect the emotions of the audience without their knowledge (Gorbman, 1987). But in some new partnerships on film projects from students, the lines between music, sound, and silence should be erased. Music could be more of a texture. The sound effects may also have the characteristics of the music. Silence could communicate information. In the usual definition of music, it highlights the phrases, timbre, and harmonic composition. When it is altered, the sound is not only “music,” but it is also in combination with the image, time, and narrative; it becomes …
