Stitched Together: Mourning And Memory In Latter-Day Saint Embroidery, Elizabeth Finlayson

Theses and Dissertations

As the Church entered into a period of mourning, confusion, and uncertainty following the 1844 imprisonment of religious leaders Joseph and Hyrum Smith in Carthage Jail in Illinois, artists turned to their canvases to grapple with and depict these events. Ashlee Whitaker calls attention to this shift in Mormon art, noting how Latter-day Saint artists painted portraits, landscapes, and commemorative scenes to promote Church authorities and “covenant kinship” as the organization experienced both a leadership crisis and abrupt relocation. Whitaker’s analysis, however, focuses almost completely on paintings done on canvas by men in America such as Danquart Weggeland, C.C.A. Christensen, …

“Music Is The Instrument To Bring The Heart Of A Community Together”: Frederic Balazs And The Tucson Symphony Orchestra, 1952-66, Jackie Bodily Biggs

Theses and Dissertations

The audience for classical music is declining, according to data from the National Endowment for the Arts. In the face of such challenges, aspiring music professionals may find inspiration in the musicological illumination of pertinent historical case studies. This paper offers one such example via a foundational exploration of the musical career of Hungarian American violinist, conductor, and composer Frederic Balazs. Though lacking any dedicated scholarly literature to speak of, Balazs’s legacy as the first full-time conductor of the Tucson Symphony Orchestra (TSO) from 1952 to 1966 included establishing arts organizations and nourishing the classical tradition at its very grass …

Principal Coaching Impact: Elementary Principals' Perspectives On Their Coaching Experience, Kyle L. Hoopes

Theses and Dissertations

School principals face increasing complexity as they navigate instructional leadership, organizational change, and the emotional demands of supporting staff and students. Traditional professional development--often episodic and compliance-driven--has proven insufficient for helping principals translate knowledge into practice. This qualitative phenomenological study examined how 20 elementary principals in a large intermountain district experienced a dual-coach, team-based leadership coaching model and how coaching influenced their leadership practices and well-being. Semi-structured interviews and iterative thematic analysis revealed that coaching shaped three core areas of leadership practice: gaining clarity and direction, prioritizing instructional and organizational goals, and strengthening collaboration within school leadership teams. Principals also …

Self-Concept Clarity And Relationship Satisfaction: The Mediating Role Of Approach And Avoidance Motives For Sacrifice Among Heterosexual Couples, Hannah F. Hatch

Theses and Dissertations

While individuals often engage in relational sacrifice to promote positive outcomes like connection (approach motives), they may also sacrifice for a partner to avoid negative outcomes like conflict (avoidance motives). These distinct motives for sacrifice have been repeatedly linked with divergent couple outcomes, yet little is known about the personal and relational factors which shape them. The current study addressed this gap using dyadic data from 289 mixed-gender couples to examine how self-concept clarity (SCC) predicted changes in relationship satisfaction via approach and avoidance motives for sacrifice. Participants represented diverse ethnic and sociodemographic backgrounds across all demographic regions of the …

The Lookahead Transformer, Justin P. Olcott

Theses and Dissertations

Large Language Models (LLMs) are transformer models that generate text autoregressively in two stages: prefill and decode. The prefill stage processes all input tokens in parallel and caches them into the KV cache. The decode stage uses the KV cache, processes a single token at a time, and is generally memory-bandwidth constrained. Each decode step generates a token probability distribution, samples from it, appends the token to the cache, and repeats. This left-to-right, one-at-a-time generation paradigm has proven effective for language modeling in many domains; however, it also has limitations such as token permanence, constant compute per token generation, constant …

Improving Reclamation Seeding Success Through Seed Technologies, Surface Preparation, And Microbial Inoculants, Josh M. De Santiago Lazalde

Theses and Dissertations

Revegetation of reclaimed lands is often limited by poor seed placement, unfavorable surface conditions, and reduced biological activity, particularly on steep or physically degraded substrates where broadcast seeding is commonly used. Improving early seeding establishment under these conditions requires approaches that address both physical and biological barriers to seedling development. We evaluated the effectiveness of surface preparation, seed technologies, and microbial inoculants for improving plant establishment in field and greenhouse settings relevant to mineland reclamation. At the field scale (Chapter 1), we investigated the effects of chain harrowing and seed enhancement treatments on the establishment of grasses, forbs, and shrubs …

Detection Of The Presence And Growth Of E. Coli Bacteria In A Droplet-Based Microfluidic System Using Laser Induced Fluorescence, Oshira Peiris

Theses and Dissertations

Antimicrobial resistance is a biomedical event, wherein an infectious microbe becomes non-responsive to the dosage of a particular antibiotic due to previous overuse or overexposure. Currently, agar plate disc diffusion is used as the gold standard for detecting antimicrobial resistance. The possibility of miniaturizing and speeding up detection techniques for antimicrobial resistance is investigated in this thesis. Microfabrication techniques were used in developing two droplet microfluidic systems interfaced with laser induced fluorescence detection. Microfluidic devices were manufactured with different droplet generating geometries using poly-dimethyl siloxane, soft lithography and hydrophobic surface treatment. The microfluidic devices were tested for droplet quality using …

The Artificial Maintenance Of Relationship Satisfaction: Romantic Ai Companion Usage Sustains Emerging Adults' Human Romantic Relationship Satisfaction While Eroding Relationship Stability, Rebekah M. Hakala

Theses and Dissertations

As artificial intelligence becomes increasingly sophisticated, romantic AI companions--AI systems designed to simulate romantic, emotional, or sexual relationships--have emerged as a novel relational phenomenon. Nearly one in four emerging adults now engage with romantic AI companions, yet little is known about how this usage affects their romantic human relationships. Drawing on Social Exchange Theory and the Investment Model of Commitment, and employing structural equation modeling, this thesis uses data from 2,431 emerging adults in romantic relationships to examine whether romantic AI companion usage influences relationship satisfaction and relationship stability among emerging adults in the United States (ages 18-30), and whether …

Impacts Of Arbuscular Mycorrhizal Fungi And Novel Soil Amendments On Perennial Grass Establishment In Mineland Soils, Melissa M. Burrell

Theses and Dissertations

Establishing perennial vegetation on mine waste materials is one of the primary challenges in mine land reclamation. Waste rock and mine tailing substrates typically lack the physical structure, nutrient availability, and biological communities necessary to support plant establishment and long-term ecosystem recovery. As a result, revegetation efforts often experience poor seeding success and limited plant persistence despite intensive management efforts. These studies investigated two complementary strategies to improve perennial grass establishment in degraded mine substrates: restoring mycorrhizal associations and enhancing soil function through soil amendments. The first study examined the role of arbuscular mycorrhizal fungi (AMF) in facilitating plant establishment …

Some Closure On The Relation Between Cfg And Peg, Nathan J. Bulloch

Theses and Dissertations

We work toward a practical, unified language formalism for structurally recursive languages by expressing the mathematical theories underlying context-free grammars with lookahead (CFGLA) in the Rocq theorem prover and leveraging CFGLA semantics to analyze interactions between between recursion and negative lookahead. We give examples of grammars with left-recursive negation cycles for the parsing expression grammar (PEG) variant due to Medeiros et al. and for the translation from PEG to CFGLA due to Miyazaki and Minamide. To study the interaction between left recursion and negative lookahead in a PEG context, we introduce FPEG, a left-recursive extension of PEG with Fitting semantics.

Integrating Traditional Samoan Music With School-Aged Children In Fostering Culturally Appropriate Behaviors Within The Framework Of Fa'afaletui And Multimodal Interpretative Phenomenological Analysis, Stormi Rachelle Winscot

Theses and Dissertations

Fa’aSamoa, the cultural framework shaping Samoan values, relationships, and daily life, deeply informs educational experiences in American Samoa. Music, as both cultural expression and communal practice, offers a powerful lens through which student engagement can be understood. This exploratory study employed multimodal interpretative phenomenological analysis (MMIPA), guided by the Fa’afaletui framework, to examine how Samoan and Pacific Islander students responded in embodied ways to traditional Samoan, culturally adapted Western, and other Western (folk, classical, pop) music in classroom settings. Drawing on focus group interviews and systematic observations, the study centered students’ movement, vocal expression, rhythmic participation, and peer interaction as …

Comparing The Effectiveness Of Telehealth Training For Parents Using “Help Is In Your Hands”: Joint Attention And Mands, Vivian Desiree Cortez Dominguez

Theses and Dissertations

This study aimed to compare the effects of remote parent training for parents of autistic children in Peru, ages 2-4 years old. Using the Spanish version of the digital program called “Help is in Your Hands” (Rogers & Stahmer, 2026; 3C Institute, 2026), three mothers were trained on how to support their child's ability to participate in joint attention and mand. Autism is a condition in which children present with challenges in engaging with others, such as sharing joint attention and using mands. Several evidence-based trainings target these difficulties. However, accessing these trainings can be expensive and time-consuming. In less-developed …

Psoas Muscle Volume Asymmetry, Not Attachment Site Asymmetry, Is Associated With Chronic Low Back Pain Status, Kassity D. Clay

Theses and Dissertations

Chronic low back pain (CLBP) is a leading cause of disability worldwide, with increasing evidence implicating neuromuscular factors such as muscle asymmetry in its pathophysiology. The psoas major muscle (PMM), a key contributor to lumbar spine stability, has been comparatively under-investigated despite its biomechanical importance. PURPOSE: To determine whether right-to-left differences in PMM volume and attachment site asymmetry are associated with CLBP; to evaluate whether ODI, IPAQ, and age are associated with PMM volume imbalance; and to assess whether combined PMM volume and attachment asymmetry are associated with CLBP. METHODS: A retrospective secondary analysis was conducted using lumbar MRI data …

"A Politics Of Its Own": Reading Adelaide Procter's Poetry In The Context Of The English Woman's Journal, Rachel Diane Gouff

Theses and Dissertations

Victorian poet Adelaide Anne Procter, a devout Catholic and a nineteenth-century feminist and social activist, was hugely popular in her lifetime for her devotional and sentimental poetry. However, scholars who have looked closely at her work have recognized that her poetry contains moments of tension that suggest they may be more than they appear on the surface. Such tensions and ironies are often glossed over or misread by readers whose expectations of Christian devotional messaging and domestic sentiment overshadow the contradictions. In this paper, I propose that one of the most effective ways to more fully understand the nuance and …

Affective Archives: Friendship And Material Intimacy In The Manuscripts Of Dora Wordsworth And Maria Jane Jewsbury, Madison Elizabeth Maloney

Theses and Dissertations

Manuscripts have long been analyzed for how they circulated alongside traditionally published texts, with scholars taking an interest in both the content and material form of such documents. In a print-centric era like the early nineteenth century, the surplus of published writing was sometimes framed as impersonal and generic. As such, material elements of manuscripts like paper, ink, and handwriting were increasingly valued as affective reflections of authors' bodies and circumstances. For example, tear stains on a letter might allow for a more personal and meaningful connection between writer and reader than the homogeneity of mass-produced texts. In a project …

Silicon Dioxide Multimode Interferometer Spectrometers, James Harkness

Theses and Dissertations

Multi-mode interferometer (MMI) spectrometers are a type of reconstructive micro-spectrometer based on imaging light propagation patterns in MMI waveguides. This dissertation describes how the MMI spectrometer was implemented for the first time using a silicon dioxide core. This approach showed a 6 dB improvement in SNR over SU-8 core devices. To implement the silicon dioxide MMI spectrometer, a fabrication technique for selectively roughening the surface of the waveguide needed to be developed. SU-8, a photosensitive polymer, was etched with oxygen plasma to create grass-like nanostructures. SU-8 grass can then be used as a transfer mask to plasma etch a surface. …

Subversive Speculative Theology In Women's Stories From The Mormon Home Literature Movement, Rachel Meibos Helps

Theses and Dissertations

In the 1910s, Mormon women used sentimental speculative fiction published in official Relief Society Magazine to engage theological questions often reserved for male ecclesiastical authority. This paper examines three short stories: Edna Coray's "A Quitter–Almost." (1918), Lucy May Green's "A Whiff of Ether" (1919), and Laura Jenkins's "Beyond the Portals" (1916), each of which depicts a woman's encounter with the spirit world at the moment of death or near-death. Drawing on the Mormon Home Literature movement and the broader tradition of sentimental fiction as political and moral discourse, I argue that these authors used narrative to fill gaps in official …

Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely

Theses and Dissertations

Polymer-coated urea (PCU) is widely used as a slow-release nitrogen (N) fertilizer because it improves N use efficiency and reduces losses through leaching, denitrification, and volatilization. However, the polymer coating raises concerns about potential microplastic (MP) transport to surface waters following fertilizer application. This thesis evaluates the off-site transport of MPs and associated nutrient and sediment losses from PCU in both urban landscape and agricultural systems. In the urban landscape study, treatments included sod, mulched beds, and water-efficient ground cover receiving uncoated urea, PCU, or liquid slow-release N at 225 kg N ha⁻¹ (with reduced rates for beds and ground …

Optimizing Seedling Emergence In Sagebrush-Steppe Restoration: The Role Of Sowing Depth, Seed Coatings, And Microsite Amendments, John Thomas Stromberg

Theses and Dissertations

Seedling survival of fall-sown seeds over the winter and subsequent emergence in spring is a major demographic bottleneck limiting recruitment in dryland restoration. Deeper sowing can place seeds in a more favorable soil environment with more stable moisture and moderated temperatures, but emergence from these depths is often constrained by the greater distance seedlings must grow to reach the surface and by mechanical resistance in the upper soil layer. In the first chapter of this thesis, we evaluated the use of a slow-release gibberellic acid (GA₃) polymer seed coating to aid in seedling emergence from deeper sowing depths. We compared …

The sample for this study was medical students at an osteopathic medical school in the Philadelphia region. Data was collected using seven validated survey instruments: …

Family Processes As A Protective Factor Between Adverse Childhood Experiences And Adolescent Delinquency, Tessa Johnson

Theses and Dissertations

This study explores whether family processes (i.e., parental attachment and parental discipline/monitoring) serve as protective factors between the relationship of adverse childhood experiences (ACEs) and adolescent delinquency. Prior research has established an association between ACEs and many negative life outcomes, including delinquent behavior, while strong parental attachment and parental discipline/monitoring are linked to lower rates of delinquency. However, the interplay of these three factors has been understudied. Drawing on data from the 2024 Florida Youth Substance Abuse Survey (FYSAS) (N=22,016), this study examines the relationship between ACEs, family processes, and delinquency using negative binomial regression models. Results indicate that parental …

Fabrication Of Su-8 Electrically Actuating Membranes, Tyler James Adams

Theses and Dissertations

This work investigates SU-8 polymer waveguides as a fabrication platform for integrated optical structures. Surface roughening using oxygen plasma etching is used to induce controlled optical scattering, enabling direct observation of guided modes and providing insight into waveguide behavior. Building on this, waveguide geometry is modified through an elevated scattering region (ESR) design, which reduces transition losses and improves scattering efficiency by preserving optical volume within the guiding region. In parallel, suspended SU-8 membranes are fabricated and evaluated for mechanical stability, providing a platform for integrating optical structures beyond conventional substrate-bound configurations. These membranes are further characterized under electrostatic actuation, …

Understanding The Role Of Tiktok As A Source Of Support For Cyberbullying Victims, Saba Iqbal

Theses and Dissertations

Cyberbullying poses a significant threat to teenagers and young adults, who often seek support and advice online. Little is known about the support and advice shared online for victims of cyberbullying and whether it is helpful. In this study, we used qualitative thematic analysis to examine a sample of 150 TikTok videos that give support or advice for cyberbullying victims. We identify 33 unique pieces of support and advice across 5 categories, with differences in tone and delivery among different types of videos. We then evaluated the quality of 33 unique pieces of cyberbullying advice in a user study with …

Democratizing National Water Model Streamflow Forecasts Through Cross-Platform Mobile Application Development, Jerson J. Garcia

Theses and Dissertations

The National Water Model (NWM) provides operational streamflow forecasts for 2.7 million stream reaches across the continental United States, yet technical barriers prevent widespread public access to this hydrological infrastructure. This paper presents RIVR (River Information Visualization and Risk), a cross-platform mobile application that transforms National Water Model forecasts into an accessible interface for non-technical users. Built with Flutter, the application deploys to iOS and Android from a single codebase and integrates NOAA forecast APIs, CIROH return-period thresholds, and interactive vector-tile mapping. Performance evaluation across six metrics: application size, startup time, memory consumption, rendering frame rates, API response times, and …

Hybrid Bermudagrass Dormancy Management In A Cool-Season Climate, Clarissa H. Peterson

Theses and Dissertations

Hybrid bermudagrass (Cynodon dactylon [L.] Pers. × C. transvaalensis Burtt Davy) (HBG) is a water efficient warm-season turfgrass increasingly adopted in cool-season and semi-arid regions due to climate change and the demand for reduced irrigation inputs. However, prolonged winter dormancy limits its visual quality (verdure) and seasonal performance. This thesis evaluated multiple management strategies to modify dormancy dynamics and improve off-season turf quality in a cool-season environment. Field experiments assessed the effects of growth covers, fertilizers, colorants, surfactants, organic acids, and overseeding with cool-season species on HBG dormancy over two seasons. Dormancy responses were quantified using normalized difference vegetation index …

The Impact Of Principal Preparation Program Components On Self-Efficacy Development In Aspiring School Leaders, Michelle Price

Theses and Dissertations

Leaders with high self-efficacy demonstrate greater persistence when facing adversity, implement organizational change more readily, and establish higher goals for themselves and their organizations. This qualitative study examines which components of principal preparation programs most strongly contribute to self-efficacy development among aspiring school leaders in Utah, specifically in instructional leadership and management for learning. Through semi-structured interviews with 19 recent graduates from three Utah universities, the research explores how program components influence candidates' confidence to lead schools effectively. Grounded in Bandura's self-efficacy theory, the findings reveal that while cohort-based models and faculty characteristics provide foundational support for overall efficacy development, …

An Efficient Approximation To The Vibrational Coupled Cluster Method For Large Molecules, Nivedhitha P Ms

Theses and Dissertations

The Watson Hamiltonian is a widely used model for describing anharmonic vibrational motion in polyatomic molecules. It expresses the kinetic energy in separable dimensionless normal coordinates and represents the potential energy as a Taylor series expansion around the equilibrium geometry, usually up to the quartic approximation. Several computational methods have been developed to solve the corresponding vibrational Schrödinger equation for predicting infrared (IR), Raman, and vibrational circular dichroism (VCD) spectra. These include the Vibrational Self-Consistent Field (VSCF) method, Vibrational Configuration Interaction (VCI) and its approximations, and Vibrational Second-Order Perturbation Theory (VPT2), each providing different balances between computational cost and accuracy. …

No Principal Left Alone: Exploring Elementary Principals' Relationships With Their Full-Time Assistant Principals, Shauna Worthington

Theses and Dissertations

Elementary school principals are often the only administrator in their building; therefore they are left to face the adverse circumstances of their job without the support of an administrative colleague at their school. However, U.S. nationwide data suggests that school districts are more frequently hiring elementary assistant principals. This paper explores perceptions of elementary principals about the nature and dynamic of their relationships with their full-time assistant principals, including accompanying benefits and challenges. This qualitative inquiry utilizes an exploratory, descriptive, phenomenological approach and features the results of in-depth interviews with 20 elementary school principals in two large suburban public school …

Entwurzelt, Melanie Fischer

Theses and Dissertations

Entwurzelt (Uprooted) is an installation that explores the emotional landscape of displacement-trauma, grief, and the search for belonging in the aftermath of war and unrest. The vessels in this installation evoke the presence of a forest--each one a symbolic tree, rooted in memory and shaped by personal and collective histories. Being torn from the familiar means leaving behind everything except memories and carrying a void that may never be fully filled. Yet, in unfamiliar places, fragments of comfort can be found--echoes of what once was. For me, the forest is more than a memory--it is a bridge between past and …

Empirical Benchmarks For Interpreting Effect Sizes In Violent Crime Interventions, Kohta James Matsukawa Hansen

Theses and Dissertations

Criminal justice researchers apply Cohen’s (1988) benchmarks to classify effect sizes as small, medium, or large, despite these standards never being meant for broad, decontextualized use (Cohen, 1988; Gies et al., 2024; Goulet-Pelletier & Cousineau, 2018; Lakens, 2013; Milner et al., 2023). Repeatedly doing so may weaken statistical validity, distort findings, and impede effective policymaking. This study introduces the first effect size benchmarks specifically designed for violent crime interventions.

Using a quasi-meta-analysis framework, 1,605 effect sizes from 104 violent crime intervention studies from the CrimeSolutions clearinghouse were converted to Cohen’s d. Three new discrete benchmarking methods were created using a …
