Affective Archives: Friendship And Material Intimacy In The Manuscripts Of Dora Wordsworth And Maria Jane Jewsbury, Madison Elizabeth Maloney Apr 2026

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 …

"But Will I Get In Trouble?": Negotiating Teacher Identity And Self-Censorship Amid Book Bans In Utah, Annika Nielson Apr 2026

"But Will I Get In Trouble?": Negotiating Teacher Identity And Self-Censorship Amid Book Bans In Utah, Annika Nielson

Theses and Dissertations

Book banning is becoming an increasingly prominent and contested issue in the United States. The focus usually lies on school and district policy, banned book lists, and state legislation, but the impact on the daily lives of teachers is often overlooked. Their decision-making processes are key to determining the books that make it into classrooms, and self-censorship often occurs prior to formal book bans (Watkins & Ostenson, 2015; Woo et al., 2023). This study examines how teachers experience book banning in their individual lives through the way they navigate competing pressures and values when selecting books to teach. Utah teachers …

Metonymy In Sound: A Neurolinguistic Study Of Al-Mullalah Soundscape Using Fnirs, Rand Naser Muflih Apr 2026

Metonymy In Sound: A Neurolinguistic Study Of Al-Mullalah Soundscape Using Fnirs, Rand Naser Muflih

Theses and Dissertations

This thesis offers an interdisciplinary exploration of the semantic and neurolinguistic development of Al-Mullalah, a traditional Palestinian "coded" song type. By combining metonymy, soundscape analysis, and functional neuroimaging, the study traces the evolution of Al-Mullalah from a localized, covert means of communication tied to historical struggle to a globally recognized auditory symbol of collective resilience. The research uses a multi-method approach. First, soundscape analysis demonstrates how Al-Mullalah functions within Palestinian aural counterpublics, strengthening communal memory through various uses. Second, a qualitative analysis of semantics and themes examines how the text's metonymic structures change over time. Lastly, a Functional Near-Infrared Spectroscopy …

Silicon Dioxide Multimode Interferometer Spectrometers, James Harkness Apr 2026

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 Apr 2026

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 …

An Examination Of K-12 Administrators' Philosophical Views On Music Education, Kathryn Ann Smith Apr 2026

An Examination Of K-12 Administrators' Philosophical Views On Music Education, Kathryn Ann Smith

Theses and Dissertations

K-12 administrators' beliefs about the purpose and value of music education have resulted in inconsistent support for students' access to music education in public schools. This study sought to examine administrators' philosophical views about music education and factors that may influence those beliefs, contributing the first known application of a praxial framework in assessing administrator belief systems. I developed a survey incorporating Song's (2025) Philosophical Beliefs Scale (Ph.B. Scale) to measure utilitarian, aesthetic, and praxial philosophical perspectives, along with key demographic and contextual characteristics. Participants (N = 65) were recruited via e-mail and K-12 administrator Facebook groups and represented a …

Evaluating Measurement Invariance Frameworks: A Comparison Of Mg-Cfa, Alignment Optimization, & Bayesian Approximate Measurement Invariance Using The Brigham Young University Counseling And Psychological Services Client Satisfaction Survey, Heidi Lula Lindsey Apr 2026

Evaluating Measurement Invariance Frameworks: A Comparison Of Mg-Cfa, Alignment Optimization, & Bayesian Approximate Measurement Invariance Using The Brigham Young University Counseling And Psychological Services Client Satisfaction Survey, Heidi Lula Lindsey

Theses and Dissertations

Researchers must establish measurement invariance (MI) before comparing latent constructs across groups to ensure construct validity. However, traditional multi-group confirmatory factor analysis (MG-CFA) may impose overly strict equality constraints in applied settings. Alternative MI frameworks are less familiar to researchers, which limits their use. This study compares MG-CFA, alignment optimization (AO), and Bayesian approximate measurement invariance (BAMI) using archival data from the Brigham Young University Counseling and Psychological Services Client Satisfaction Survey (N = 1,278). Participants completed an exit survey after receiving individual (n = 1,063), couple (n = 83), or group (n = 132) therapy, answering 16 five-point Likert …

Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely Apr 2026

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 …

Asymptotic Sensitivity And Adjoint Methods For Equation Discovery With Open-Source Implementation, Nathan Schill Apr 2026

Asymptotic Sensitivity And Adjoint Methods For Equation Discovery With Open-Source Implementation, Nathan Schill

Theses and Dissertations

The "on-the-fly" (OTF) method is a gradient-based approach to equation discovery. It makes use of (potentially limited) observational data, a data assimilation technique such as continuous data assimilation (also called nudging), and an error metric. From these it computes an asymptotic approximation of a simulated system's error sensitivity with respect to unknown parameters and utilizes any gradient-based optimization algorithm to perform parameter updates. These parameter updates may be done online or offline, and the model may be of a precisely specified form or simply a library of possible terms with potentially nonlinear parameters. We have applied the adjoint method to …

Stack-Based Exploit Development Techniques In Mips Architectures, Justin Applegate Apr 2026

Stack-Based Exploit Development Techniques In Mips Architectures, Justin Applegate

Theses and Dissertations

Memory corruption vulnerabilities in binary executables represent a serious threat to software security, particularly in embedded and IoT (Internet of Things) devices that commonly use the MIPS architecture. While exploit development techniques for x86 are well-documented in academic literature, little systematic work exists on how those techniques translate to other architectures such as MIPS. This research addresses that gap by evaluating thirteen stack-based exploit development techniques and subtechniques, originally designed in the context of the x86 architecture, for their applicability to MIPS architectures. For each technique, vulnerable C code was written and compiled into both x86 and a set of …

Conditioned Synthesis Of Spectra Using Matrix Decomposition For Spectral Library Augmentation, Anna Catherine Rollans Apr 2026

Conditioned Synthesis Of Spectra Using Matrix Decomposition For Spectral Library Augmentation, Anna Catherine Rollans

Theses and Dissertations

In hyperspectral imaging, identification and detection tasks are often done by comparing the spectrum of an unknown material to labeled spectra in a spectral library. However, it is intractable to populate a spectral library with measurements of all possible materials in all possible conditions. We propose modeling the weights resulting from matrix decomposition as functions of material condition(s) to generate synthetic spectra at unmeasured conditions to augment spectral libraries. Matrix decompositions considered here include principal component analysis (PCA), non-negative matrix factorization (NMF), and independent component analysis (ICA).We demonstrate this method by generating (1) synthetic long-wave infrared (LWIR) emissivity spectra of …

Optimizing Seedling Emergence In Sagebrush-Steppe Restoration: The Role Of Sowing Depth, Seed Coatings, And Microsite Amendments, John Thomas Stromberg Apr 2026

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 …

Space-Time Coded Pcm/Fm For Aeronautical Mobile Telemetry, Zachary B. Hilton Apr 2026

Space-Time Coded Pcm/Fm For Aeronautical Mobile Telemetry, Zachary B. Hilton

Theses and Dissertations

This thesis describes the application of a space-time block code for the legacy continuous phase modulation called "PCM/FM" in the IRIG 106 standard to solve the "two-antenna problem". This problem arises when two transmit antennas are used for full spatial coverage at the cost of self-interference caused by the different delays between the transmit antennas and the ground-based antenna. The space-time block encoder is described using bit-level operations on the input data stream. The space-time decoder uses coherent combining and maximum likelihood sequence estimation to produce an estimate of the data sequence. Simulation results for zero and various non-zero differential …

Unlocking Inexpensive Training Through Overcoming Weaknesses In Dataset Distillation, Connor Wilhelm Apr 2026

Unlocking Inexpensive Training Through Overcoming Weaknesses In Dataset Distillation, Connor Wilhelm

Theses and Dissertations

Dataset distillation is a nascent technique that promises accelerated neural network training. In particular, distillation produces a highly compressed dataset that can train a neural network in as little as a single optimization step. However, distillation has not been adopted for real-world use cases due to weaknesses, such as poor approximation of the original task, unclear interpretability, high costs of the initial distillation, and poorly elaborated use cases. Here, we present five papers that advance task distillation towards real-world adoption. The papers focus on: distilling reinforcement learning environments, interpreting distillation-produced datasets, improving distillation performance using ensembling, examining distillation's generalization to …

Toward Human-Like Robot Behavior In Co-Manipulation: Learning From Human Dyad Performance, Adam Kenneth Jackson Apr 2026

Toward Human-Like Robot Behavior In Co-Manipulation: Learning From Human Dyad Performance, Adam Kenneth Jackson

Theses and Dissertations

Co-manipulation requires two or more agents to coordinate through a shared object while exchanging information through motion and force. Although this capability is routine for humans, robotic systems still struggle to participate in such interaction naturally and effectively. This thesis addresses that gap by studying human co-manipulation behavior, developing methods to quantify performance, collecting a leader-follower dataset that isolates haptic communication, and training data-driven controllers from human demonstrations. First, cumulative and real-time metrics were developed to quantify human dyad performance. In particular, the behavioral modes "quickly" and "smoothly" were formulated as measurable performance objectives using completion time and squared jerk. …

3d Printed Microfluidic Nonlinear Structures For Implementing Lab-On-A-Chip Integrated Logic Control, Marshall J. Rawlins Apr 2026

3d Printed Microfluidic Nonlinear Structures For Implementing Lab-On-A-Chip Integrated Logic Control, Marshall J. Rawlins

Theses and Dissertations

Microfluidic devices are individual chips that manipulate small quantities of fluid to perform, for example, biomedical assays. They provide a compact apparatus for conducting chemical processes while using only micro-liter quantities of potentially expensive chemical reagents. Continued research in microfluidics has brought significant achievements in reducing microfluidic feature sizes, allowing for microfluidic systems to be more densely packed and designed for more complex chemical assays. However, this comes with the need for additional control inputs which require additional external equipment to generate the control inputs. This leads to crowding of external inputs, or an increase in chip volume to accommodate …

Physics-Based And Data-Driven Low-Order Modeling Of Centrifugal Compressors, Chase Oliphant Apr 2026

Physics-Based And Data-Driven Low-Order Modeling Of Centrifugal Compressors, Chase Oliphant

Theses and Dissertations

Centrifugal compressors serve as critical components across many applications, yet their design and performance prediction present significant challenges. While computational fluid dynamics provides high-fidelity predictions of compressor behavior, its prohibitive computational cost renders it impractical for preliminary design phases where rapid exploration of the geometric and operating space is essential. Conversely, existing low-order models have enabled efficient performance estimation but suffer from limited accuracy and poor interpretability, particularly when applied to novel geometries or off-design operating conditions. This dissertation addresses these limitations through three complementary contributions that bridge the gap between high-fidelity CFD and preliminary design tools. The first contribution …

Biophysical Insights Into A Cryptic, Hydrophobic Binding Site On Pcna, Alexis Dispensa Apr 2026

Biophysical Insights Into A Cryptic, Hydrophobic Binding Site On Pcna, Alexis Dispensa

Theses and Dissertations

Proteins are dynamic molecules whose functional landscapes extend beyond static structural representations. Transient cryptic pockets (buried cavities that emerge through protein motion) represent underexplored targets for allosteric regulation and drug discovery. General anesthetics are small, lipophilic, weakly polar molecules that are well suited to partition into such hydrophobic sites. In this work, environment-sensitive fluorescence, photoaffinity labeling, mass spectrometry, mutational analysis, and microsecond molecular dynamics simulations were integrated to discover and characterize a cryptic, highly apolar binding site within the hydrophobic core of human proliferating cell nuclear antigen (PCNA), a central scaffold in DNA replication and repair. Using the solvatochromic fluorescent …

Development Of An Experimental Platform For Hydrogen-Propelled Cold Spray, Michael James Katz Apr 2026

Development Of An Experimental Platform For Hydrogen-Propelled Cold Spray, Michael James Katz

Theses and Dissertations

Cold spray (CS) has gained recent interest as an additive manufacturing process. This process uses high pressure propellant gas to accelerate solid-state powder particles through a specialized nozzle, beyond which the powder deposits onto a substrate as a dense coating and without either material undergoing a phase change. Both nitrogen (N2) and helium (He) are commonly used as CS propellants, with He generally yielding superior results at otherwise similar processing conditions. However, performance advantages of He come with a significant drawback: He is a limited resource that may be sensitive to geopolitical conflicts and, in recent history, has been subject …

Family Processes As A Protective Factor Between Adverse Childhood Experiences And Adolescent Delinquency, Tessa Johnson Apr 2026

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 Apr 2026

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, …

Path Planning And Control For Vertical Takeoff And Landing Aircraft, Dean Benjamin Anderson Apr 2026

Path Planning And Control For Vertical Takeoff And Landing Aircraft, Dean Benjamin Anderson

Theses and Dissertations

One of the challenging problems of unmanned aerial vehicles (uav) is controlling vertical takeoff and landing (vtol) aircraft. Vtol aircraft can take off and land without landing strips while retain the efficiency of fixed-wing airplanes for long range flight. Unfortunately, the transition from takeoff and forward flight, and from forward flight to landing, is an extremely difficult control problem. Most current controllers for transition switch between flight regimes based solely on airspeed. The trajectory for such switching transitions is a straight vertical ascension followed by a straight forward startup flight; it does not allow for the development of more complex …

Hybrid Bermudagrass Dormancy Management In A Cool-Season Climate, Clarissa H. Peterson Apr 2026

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 …

Hypertext Transfer Protocol Fingerprinting: Techniques For Attacker-In-The-Middle Proxy Detection, Evasion, And Counter-Evasion, Jensen George Wood Apr 2026

Hypertext Transfer Protocol Fingerprinting: Techniques For Attacker-In-The-Middle Proxy Detection, Evasion, And Counter-Evasion, Jensen George Wood

Theses and Dissertations

Attacker-in-the-middle (AitM) phishing toolkits have emerged as a critical threat to enterprise and individual security by enabling adversaries to bypass multi-factor authentication (MFA) and compromise cloud-based accounts at scale. Traditional detection techniques--such as IP blocklists or content-based detection methods--are often ineffective against these increasingly sophisticated attacks. We propose a novel method that detects malicious proxies by identifying artifacts they introduce into HTTP request headers. To evaluate our approach, we systematically analyze traffic passed through several open-source AitM toolkits and proxies, identifying distinct modifications to header structures and content, then formalize these features as YARA rules for automated use. To validate …
