Spatiospectral Lobes And Radiation Modeling Of Partially Coherent Supersonic Jet Noise, Tyce Wayne Olaveson

Theses and Dissertations

Noise fields generated by high-performance military jets are known to contain acoustic structures that differ from their simulated and lab-scale counterparts. These differences may limit current noise control efforts, which are designed and tested at scale before being considered for full-scale aircraft. One such noise structure is the presence of spatiospectral lobes, which appear as multiple spectral peaks at single microphone locations and multiple radiation lobes in field reconstructions. This dissertation uses data collected from the T-7A jet noise measurement to characterize the spatial behavior of the spatiospectral lobes as well as their first time-domain description. A multiple wavepacket decomposition …

Same-Subject Induction Experiences For Elementary Music Teachers: Teacher Efficacy Beliefs, Experiences Of Isolation, And Job Satisfaction, Wendy Tams Hickman

Theses and Dissertations

This survey study seeks to explain the relationships between elementary music teachers' experiences with same-subject induction support and those teachers' feelings of teacher efficacy, experiences of isolation, and job satisfaction. Independent variables came from latent class groupings of same-subject induction support for beginning elementary music teachers. Teacher background variables were also included as controls. Three- and four-step regression models helped provide understanding about how the relative set of predictors--teacher background variables, isolation levels, induction experiences, and interaction terms--predicted the three outcomes. Initial regression analyses showed that the number of years of teaching elementary music predicted efficacy and levels of isolation …

Functional And Structural Lesion Network Mapping: Insights Into Acquired Brain Injury And Insomnia, Kathleen Erekson Rugh

Theses and Dissertations

Insomnia disorder is the most reported sleep disorder and can negatively affect daily functioning. Acquired brain injuries can lead to insomnia disorder. Limited research has explored a causal link between brain networks and insomnia symptoms in this population. This study replicated a lesion network mapping methodology of an insomnia study (Helquist et al., 2024) and extended it to examine structural networks linked to insomnia symptoms in individuals with acquired brain injuries. Traced lesions (N =44) were used as seed regions to compare against normative functional and structural network data. For functional analyses, we used resting state fMRI scans from a …

Beyond Pedagogical Inertia: Understanding And Overcoming The Barriers To Effective Faculty Work In Higher Education, Yoshihiko Ariizumi

Learning, Teaching, & Researching Optimization

Academic faculty are among the most educated professionals in the world. Yet a striking body of empirical research demonstrates that they face profound, systematic barriers to performing their own work effectively—barriers that are cognitive, institutional, cultural, and structural in origin. This paper extends the analysis of “pedagogical inertia” beyond the classroom to the full scope of faculty professional life: research, writing, service, advising, and self-directed learning. Drawing on evidence from organizational psychology, cognitive neuroscience, higher education research, and behavioral science, we identify six classes of barriers that consistently impede effective faculty work, and we analyze—with reference to documented successful cases—the …

Empowering Audio Recording: Academic Supporting Views, Yoshihiko Ariizumi

Learning, Teaching, & Researching Optimization

This paper aims to demonstrate, drawing on findings from cognitive science, educational psychology, and creativity research, the proposition that incorporating voice recording into daily intellectual production activities can substantially enhance individual intellectual productivity.

One of the greatest challenges facing contemporary knowledge workers and learners is the asymmetry between the difficulty of securing uninterrupted time for thinking, on the one hand, and the latent abundance of fragmented “half-released” time in daily life—during commutes, household chores, exercise, waiting, and the like—on the other. This study proposes a methodology for resolving this asymmetry through recording technology.

As the conceptual framework of the paper, …

Analysis Of Approximations In Flash Thermal Diffusivity Measurements Using High‑Fidelity Simulations, Tage T. Burnett, Jakob G. Bates, Matthew R. Jones, Christopher R. Dillon, John Tencer

Faculty Publications

Thermal diffusivity is an important material property for understanding and characterizing transient behavior in many heat transfer applications. This study investigates the accuracy and approximations of inverse mathematical models for measuring thermal diffusivity of materials via the widely used Flash Method. High-fidelity simulations of the Flash Method in copper, silicon carbide, silicon, and glass were performed as numerical experiments and included physics such as in-depth absorption, radial conduction, and surface convection. Data from those numerical experiments were used to estimate material thermal diffusivity using seven traditional and new inverse models. Parker’s original model had relative errors 𝜖< 5% when the approximations it makes were enforced in numerical experiments. Newer models performed well even when experimental restrictions were relaxed. Models that include radial heat conduction were capable of accurately measuring thermal diffusivity (𝜖< 1%) when a Gaussian energy source was used. Models with radial conduction and in-depth material absorption of the laser source could calculate thermal diffusivity for semi-transparent materials such as silicon (𝜖< 1%) and even transparent materials like glass (𝜖< 10%). Convective losses from the material’s front surface had a negligible impact on measurements except for very low thermal diffusivity materials. Using temperatures from many locations of the test material’s surface increased resilience to noise, reducing the distribution of thermal diffusivity measurements by more than an order of magnitude. The models developed in this study could enable a more relaxed Flash Method experimental setup that maintains thermal diffusivity accuracy and extend the utility of the Flash Method to semitransparent materials.

“Thomas Jefferson: America’S Flawed Founder Of Freedom.”, Jay H. Buckley

Faculty Publications

Thomas Jefferson was a deeply paradoxical figure—both a founding champion of liberty and a lifelong slaveholder—whose legacy must be understood in its full complexity. While he owned more than 600 enslaved people and participated in a system he publicly condemned, Jefferson consistently articulated and promoted ideals of natural rights, equality, and freedom that reshaped the United States and influenced democratic movements worldwide. He made repeated (though often unsuccessful) efforts to curb or end slavery through legislation, legal cases, and policy, including opposing the slave trade, limiting slavery’s expansion into western territories, and helping abolish the transatlantic slave trade. At the …

Separating Access Legitimacy From Utilization Analytics: A Two-Layer Evaluation Model For Philanthropy And Development, Stephanie Zabriskie

Journal of Nonprofit Innovation

This article introduces a two-layer evaluation model for philanthropic and development decision-making in access-based interventions. The first layer treats Access as Outcome (AAO) as a recognized outcome when essential goods, services or resources are delivered through a viable delivery pathway, without requiring post-access utilization or compliance to validate legitimacy. The second layer evaluates post-access variation through System Coherence Conditions (SCC), defined as internal alignment across governance and decision-making, distribution and logistics, social accountability and norms, and scarcity management and continuity, which explain differences in utilization, continuity, and downstream effects as signals of system coherence rather than as retroactive worthiness thresholds. …

Framing Digital Donation: Innovation And Audience Engagement In Short Video Fundraising On Douyin, Qiuyi Chen

Journal of Nonprofit Innovation

Short video platforms are increasingly adopted by nonprofit organizations as tools for charitable communication and fundraising. However, limited research has examined how donation appeals are structured and interpreted within these environments. Existing studies focus on emotional appeal, influencer involvement, and algorithmic visibility, yet donation is often treated as a behavioral outcome rather than as a communicative process.

This study conceptualizes charitable donation as a social situation that must be framed and recognized by audiences in short video contexts. Drawing on Goffman’s frame analysis and employing the Visual–Verbal Video Analysis (VVVA) method, the study analyzes 32 publicly available videos from a …

Advanced Studies In Characterization Of Pyrolysis Products From Live Vegetation, Mahsa Alizadeh

Theses and Dissertations

Fire is a naturally occurring element in many ecosystems which can have both positive and negative effects. However, in recent years the frequency of the fires and the area they affect has increased. The rapid spread of wildland fires coupled with the limited resources available to forest services to manage wildland fires highlights the urgency for accurate prediction of fire spread. Fire prediction models enable the fire management services to predict the spread of fire and prioritize firefighting efforts more effectively. Understanding reactions and mechanisms occurring during wildland fires improves the fire prediction models. During wildland fires, the biomass covering …

Robust And Interpretable Cross-Domain Arabic Readability Prediction Using Hybrid Modeling: Evidence On The Limitations Of Transformer-Based Classifiers, Sarah Alzu'bi

Theses and Dissertations

Automatic readability assessment aims to predict how difficult a text is for readers to understand. The concept of readability has been widely studied across languages due to its significant impact on reading comprehension, leading to the development of various methods and approaches. In this study, I addressed two key challenges in readability assessment. First, I examine the performance of statistical classifiers and transformer-based models, including CAMeLBERT(Inoue et al, 2021.) with a focus on their ability to generalize under domain, genre, and stylistic shifts. Second, I investigate the interpretability of transformer performance in readability task, which are often criticized for their …

“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 …

Domain-Specific Fine-Tuning Of Neural Machine Translation For Georgian Religious Texts, Jacob Brent Fisher

Theses and Dissertations

This thesis investigates whether domain-specific fine-tuning of a large multilingual neural machine translation model improves translation quality for English-to-Georgian religious text, a low-resource pair underserved by existing systems. Using the 1.3-billion-parameter NLLB-200 model as a baseline, two LoRA-adapted variants were trained: General-FT, on 91,143 parallel segments of contemporary religious discourse drawn from the General Conference talks and other publications of The Church of Jesus Christ of Latter-day Saints, and Scriptural-FT, on 33,229 segments from the scriptural canon of The Church. The three models were evaluated using automated metrics (BLEU, chrF, COMET) covering both domain-matched and cross-domain conditions, and on a …

The Relational Good Life: Entrepreneurship Education And Grounded Sumak Kawsay In Otavalo, Ecuador, Vanessa I. Lozano Hardman

Theses and Dissertations

Indigenous Kichwa communities in Ecuador’s Otavalo region have long participated in local and transnational markets, historically as mindalaes, specialized traders of the northern Andes. Yet in recent years, international development-oriented NGOs have framed entrepreneurship education as newly necessary for economic development. These approaches emphasize individualized narratives of vision, self-reliance, and growth, often characterizing Indigenous peoples as lacking entrepreneurial skills or the appropriate mindset. Drawing on ethnographic research with youth, mothers, and teachers at Saminay–El Legado, an agro- technical, intercultural bilingual secondary school (UECIB) in the parish of San José de Quichinche, this article examines how entrepreneurship education intersects with grounded …

Independent English Teaching In Brazil: A Case Study, Jade G. Gunca

Theses and Dissertations

This qualitative case study investigates the experiences and practices of successful independent English as a Foreign Language (EFL) teachers in Brazil who operate outside traditional schools and private language institutes. Rather than providing a broad descriptive profile, this study offers an in-depth examination of a small group of teachers. These educators frequently use social media platforms such as Instagram and Facebook to showcase communicative, personalized, and flexible instruction in response to growing learner demand. Although English is widely taught in Brazilian schools, persistent structural constraints often limit students’ development of communicative proficiency, prompting some learners to seek instruction from independent …

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, …

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 …

Answers “Go By Water”: Felt Knowledge As An Alternative Epistemology In Othello, Annalisa Gulbrandsen

Theses and Dissertations

William Shakespeare's Othello is fundamentally a play about epistemology--how does one know what he/she knows amidst the sea of words, evidence, and misdirection? Traditionally, the problem of knowledge in Othello has been treated as an intellectual problem of the mind. However, this thesis argues that the play purposefully draws attention to the limits of what the mind can know by way of the eye (what is seen) and ear (what is spoken or heard), instead offering an alternative epistemology that is felt through embodiment. When Desdemona's words no longer have the power to affect what Othello believes, Desdemona's answers to …

Model Unification: A Systematic Approach For The Cluster Expansion, Kolten Barfuss

Theses and Dissertations

A systematic approach for model unification of cluster expansion models is developed and demonstrated. The method builds on previous work with the Manifold Boundary Approximation Method (MBAM) to identify supremal models. The work is motivated by the exercise of unifying cluster expansion models – characterized by Π matrices – for two binary alloys that share one atomic species to form a model for the ternary alloy. The result is the Supremal Π Algorithm, a systematic unification algorithm that relies on an MBAM-informed understanding of models and on the singular value decomposition. The algorithm yields ΠΛ, a Π matrix for the …

Additionally, internal battery temperature was measured and compared to real average furnace temperature to monitor thermal runaway. Testing showed minimal …

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 …

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 …

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 …

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 …

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 …
