Foreign Language Experience Effects On L2-Accented Speech Attitudes In College Students, Jordan L. Ellington
Foreign Language Experience Effects On L2-Accented Speech Attitudes In College Students, Jordan L. Ellington
Theses and Dissertations
The purpose of the study is to test whether knowledge of a second language in college students can affect perceptions and prejudices towards speakers with foreign accents. The testing was completed through both implicit and explicit attitudinal measures in regard to recorded audio stimuli. The explicit attitudinal testing was performed through participant self reporting of attitudes. Participants were presented with first (L1) or second (L2) language accented English samples and then rated that speaker in terms of various characteristics or traits that represented the speaker's solidarity and status. The implicit testing was performed in an Auditory Implicit Associations Test on …
Recognizing Metaphorical References To Sexual Assault Resistance And Represented Rape Myths In Coraline (2009), Braden Slater
Recognizing Metaphorical References To Sexual Assault Resistance And Represented Rape Myths In Coraline (2009), Braden Slater
Theses and Dissertations
Is there any value in children’s horror literature and film? Literary theorists have shown that children’s horror is uniquely positioned to be not only captivating and accessible, but also educational and hopeful for some young audience members. Like most fictional monsters, those presented in children’s horror can be read as metaphors for the fears and experiences people face in real life. Scholars have argued that engaging with this type of frightening media may help people confront challenging ideas and feelings from a place of safety. Building on this theoretical foundation, I perform a close reading of the 2009 film Coraline, …
Liminality And Space In The Iliad And The Heike Monogatari, Jade Simmons
Liminality And Space In The Iliad And The Heike Monogatari, Jade Simmons
Theses and Dissertations
Both the Iliad and the Heike monogatari have received scholarly attention throughout the years, though rarely in comparison with one another. A few scholars, such as Tyler Creer and Naoko Yamagata, have attempted to examine the two side by side, but very little work has been done beyond their respective analyses. This is unsurprising as a cursory glance at the two texts suggests that they are too separated by time and space to warrant closer examination. I argue, however, that there is great value in analyzing the two side by side. Indeed, a closer look at these texts reveals that …
Gratitude And The Second Language Writer: The Effects Of Gratitude Journaling In The English Language Writing Classroom, Lauren Smith
Gratitude And The Second Language Writer: The Effects Of Gratitude Journaling In The English Language Writing Classroom, Lauren Smith
Theses and Dissertations
Gratitude journaling interventions have repeatedly been shown to enhance wellbeing when conducted in participants’ first language (Emmons & McCullough, 2003; Sansone & Sansone, 2010), yet no studies to date have examined these practices in second language (L2) contexts. This mixed-methods quasi-experimental study investigated the effects of a six-week gratitude journaling intervention on adult L2 English writers enrolled in an intensive English program. Eleven writing classes (N = 183) were randomly assigned to either a gratitude journaling group or a neutral-events control group, with 123 participants completing all four stages of data collection. Trait gratitude and subjective wellbeing were measured pre-intervention, …
Exploring Subject-Verb Agreement Challenges Among Third-Grade Portuguese Dual Language Immersion Students: A Mixed-Methods Study, Marisa Tobias
Exploring Subject-Verb Agreement Challenges Among Third-Grade Portuguese Dual Language Immersion Students: A Mixed-Methods Study, Marisa Tobias
Theses and Dissertations
Dual Language Immersion (DLI) programs are commonly recognized for supporting the development of oral proficiency; however, persistent challenges with grammatical accuracy, particularly subject-verb agreement, remain common among elementary-aged learners. This mixed-methods study focuses on third-grade students in a Portuguese DLI program and examines how they use present-tense verb forms in different classroom contexts. Drawing on classroom observations, instructional materials, and students’ oral and written production, the study analyzes the nature of the input learners receive and the types of errors that persist during oral communication. Findings indicate that students demonstrate greater accuracy during structured tasks, while difficulties with subject-verb agreement …
Mcgehee Blow Up And Collision Manifold Of Planar (2+2)-Body Problem, Nathaniel Scott Sill
Mcgehee Blow Up And Collision Manifold Of Planar (2+2)-Body Problem, Nathaniel Scott Sill
Theses and Dissertations
This thesis analyzes the dynamics of the Planar (2+2)-Body Problem which consists of two asteroids moving under the gravitational force of each other and of two larger primaries. We use the McGehee blow up technique to remove the singularities in the dynamics associated with a triple collision with one of the primaries by introducing a new set of variables. Additional variables are introduced to reduce the dimension of the problem. We then derive the dynamics for these new variables. We then use the energy relation that comes from the original Hamiltonian to describe the collision manifold which is pasted in …
Differentiable Objectives For 3d Scene Relighting Via Gradient Descent On Olat Basis Coefficients, Anson Savage
Differentiable Objectives For 3d Scene Relighting Via Gradient Descent On Olat Basis Coefficients, Anson Savage
Theses and Dissertations
Designing effective lighting is an iterative and often time-consuming process. This work contributes to automatic lighting design research by presenting a render-engine agnostic optimization routine: gradient descent on RGB multipliers of one-light-at-a-time (OLAT) basis images. We compare several objective functions to accomplish lighting tasks and show that our method is capable of quickly and effectively exploring different lighting styles using either text prompts or reference images. We also present several datasets specific to lighting tasks and show that fine-tuning on these datasets can improve performance.
Advanced Studies In Characterization Of Pyrolysis Products From Live Vegetation, Mahsa Alizadeh
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 …
The San José De Laguna Mission: Christian Iconography Through The Lens Of Pueblo Oral Traditions, Natalie Sims Rasmussen
The San José De Laguna Mission: Christian Iconography Through The Lens Of Pueblo Oral Traditions, Natalie Sims Rasmussen
Theses and Dissertations
The San José de Laguna Mission was constructed in 1699 in modern New Mexico. Following on the heels of the second Pueblo revolt, it stands as a testament to the Pueblo adoption of Christian symbols in the portrayal of their own oral traditions. A central theme in the Laguna oral tradition is the complementary nature of masculine and feminine forces that make up the universe. The Christian figures of the altar screen, such as Saint Joseph, Saint John Nepomuck, Saint Barbara, and the Trinity, can be interpreted through the lens of the Pueblo oral tradition regarding a 19th century Laguna …
Maximizing Uinta Basin Oil Well Yield Through Geochemical Fingerprinting Of Produced Water, Troy W. Day
Maximizing Uinta Basin Oil Well Yield Through Geochemical Fingerprinting Of Produced Water, Troy W. Day
Theses and Dissertations
The Uinta Basin is an unconventional oil play that has, since 2017, annually increased hydrocarbon extraction through modern drilling and fracing techniques with increased frac loading. The primary production target is the Uteland Butte Member of the Green River Formation, which consists of interbedded limestones, dolostones, and thick, organic-rich mudstones. Along with increased hydrocarbon production, volumes of produced water from the Uteland Butte Member have also risen. Water is co-produced with hydrocarbons and is an undesirable byproduct of hydrocarbon extraction. Large frac operations now consistently have highly variable percentages of recovered water volume relative to oil. This increase in water …
Improving Electrochemical Measurements And Informing Future Reprocessing Of Advanced Nuclear Fuels, J. Marvin Torrie
Improving Electrochemical Measurements And Informing Future Reprocessing Of Advanced Nuclear Fuels, J. Marvin Torrie
Theses and Dissertations
This research promotes the application of molten salts through developing analytical tools in electroanalytical studies and in the data analysis of vapor pressure data. The electrochemical community lacks standardized, stable, and repeatable reference electrode designs which threaten the reliability of measured thermophysical properties and repeatability of published studies. This work confirms the application of a saturated reference electrode design for molten chlorides systems that outperforms traditional Ag+/Ag reference electrodes. In the field of thermal physical property measurements, vapor pressure data for chloride salts are diffused throughout the literature, uncertainty quantification is absent or limited, and all previous studies rely on …
These Wretched Waters: A New Perspective On The Myth Texts And Visual Adaptations Of The Danaids, Tessa Haney
These Wretched Waters: A New Perspective On The Myth Texts And Visual Adaptations Of The Danaids, Tessa Haney
Theses and Dissertations
Both Greek and Latin texts regarding the Danaids are rife with gestational imagery and vocabulary. This textual focus on chthonic, symbolic aparturience coheres with both Greek and Roman perceptions of femininity. Women in both cultures were socially mandated to marry, have children, and confine themselves to the domestic sphere. The Danaids’ refusal to participate in this system would have been viewed as a breach of cosmic order, and a punishment that grounded the sisters in their 'traditional’ femaleness would have been viewed as a solution to such a breach. While early modern visual adaptations of the Danaid myth lack gestational …
Stitched Together: Mourning And Memory In Latter-Day Saint Embroidery, Elizabeth Finlayson
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, …
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
“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 …
Probing The Disequilibrium Chemistry Of Two Late T-Dwarfs Using Planetary Intensity Code For Atmospheric Scattering, Crystal-Lynn Jacqueline Bartier
Probing The Disequilibrium Chemistry Of Two Late T-Dwarfs Using Planetary Intensity Code For Atmospheric Scattering, Crystal-Lynn Jacqueline Bartier
Theses and Dissertations
We have performed a detailed analysis of the atmospheric properties of two late-T type brown dwarfs, 2MASSI J0415195-093506 and 2MASS J05591914-140448. For each brown dwarfs, we combined the spectra of each brown dwarf from the ground at 1-2.5 µm, AKARI at 2.5-5 µm, and from the Spitzer Space Telescope at 5-15 µm. For this project, we are particularly interested in probing the extent of vertical mixing. For this analysis, we used the Planetary Intensity Code for Atmospheric Scattering (PICASO), which is a code that creates a radiative transfer model for a given set of atmospheric parameters. With PICASO we find …
The Relational Good Life: Entrepreneurship Education And Grounded Sumak Kawsay In Otavalo, Ecuador, Vanessa I. Lozano Hardman
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
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 …
Domain-Specific Fine-Tuning Of Neural Machine Translation For Georgian Religious Texts, Jacob Brent Fisher
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 …
A Masked-Perturbation Model For Destabilization Security Games In Feedback Systems, Gabriel Michael Perry
A Masked-Perturbation Model For Destabilization Security Games In Feedback Systems, Gabriel Michael Perry
Theses and Dissertations
In this thesis, we present a mathematical formulation for increasing cyberphysical system security. This model allows a system administrator to use assumptions about exposed signals to derive defense strategies meant to mitigate the system's vulnerability to feedback perturbation attacks. We begin with a survey of game theory with the goal of building the concepts of resource and security games. We then introduce our model, which is a security game; targets in this game are exposed signals in the model map of the system, and resources are perturbed or introduced dynamical relationships between these signals. This formulation, called the masked-perturbation model, …
Theoretical Expressivity Of Self-Attention As A Model Of Binary Sequence-To-Sequence Functions And Other Explorations, Dustin Angerhofer
Theoretical Expressivity Of Self-Attention As A Model Of Binary Sequence-To-Sequence Functions And Other Explorations, Dustin Angerhofer
Theses and Dissertations
The self-attention mechanism lies at the heart of modern sequential modeling with deep neural networks, especially in the context of Large Language Models (LLMs). The basic role of self-attention is to capture pairwise interactions between tokens in a sequence. This allows token embeddings to be endowed with context-dependent information before further processing. Despite its widespread use, our theoretical understanding of self-attention is still nascent. In this work, we examine self-attention as a model of binary sequence-to-sequence (seq2seq) functions, which is the simplest non-trivial case to analyze. We find, using VC dimension and the Sauer-Shelah lemma, that in the limit of …
Principal Coaching Impact: Elementary Principals' Perspectives On Their Coaching Experience, Kyle L. Hoopes
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
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
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 …
Studies On The Contribution Of Osh6 To The Functions Of Late Endosomes, William King
Studies On The Contribution Of Osh6 To The Functions Of Late Endosomes, William King
Theses and Dissertations
The late endosome (LE) is a hub organelle connecting endocytic, biosynthetic, exocytotic, and autophagic vesicle traffic pathways. Malfunctions of LEs are associated with multiple age dependent diseases such as Parkinson’s disease (PD). Despite this significance, how cells refurbish lipids and proteins to LEs to maintain their sustained activities are not clear. Previous studies in the model organism budding yeast show that up-regulation of a lipid transporter Osh6 (PERG6-OSH6) accumulates phosphatidylinositol-4-phosphate (PI4P) on the trans-Golgi network. It also promotes vacuole fusion and maintains the robustness of vacuoles in aged cells. Since LEs are the organelle between the TGN and vacuoles in …
Improving Reclamation Seeding Success Through Seed Technologies, Surface Preparation, And Microbial Inoculants, Josh M. De Santiago Lazalde
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
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
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
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 …
Mild Thermal Treatment Of Lithium-Ion Batteries To Optimize Black Mass Production, Brooke Lillie
Mild Thermal Treatment Of Lithium-Ion Batteries To Optimize Black Mass Production, Brooke Lillie
Theses and Dissertations
This thesis explains the design of equipment and the experimental procedure for thermal treatment of lithium-ion batteries for the purpose of low-cost materials recycling. Conditions used were between 150 ℃ and 425 ℃, involving different atmospheric conditions and treatment durations. The battery samples were processed through a sieve shaker device. Mass loss during the heat treatment, and separation of the battery through sieving was used to analyze the effect of the treatments on separability of black mass from the batteries. Additionally, internal battery temperature was measured and compared to real average furnace temperature to monitor thermal runaway. Testing showed minimal …
