Measuring Proteostasis Changes In Apolipoprotein E Mouse Models Using Quantitative And Kinetic Proteomic Methods, Ariel E.A. Denos

Theses and Dissertations

Alzheimer's Disease (AD) is a neurological disorder associated with brain mass loss and cognitive decline. It affects millions of elderly people and is currently uncurable. Since 1906, when the disease was first described, researchers have uncovered many components of AD pathology. However, it is now evident that curing Alzheimer's Disease will require intervention before the pathological onset of amyloid beta plaque deposition, tau neurofibrillary tangles, and associated neuronal loss. Studying AD from the perspective of early intervention requires special attention to small changes that may disrupt the normal processing of cells. Cells undergo a natural cycle of creation and destruction …

Multi-Band Extinction Modeling In Early-Type Galaxies With Circumnuclear Disks, Nonnie Bash

Theses and Dissertations

In this thesis, we present a spatially resolved, multi-band dust-attenuation method for correcting the stellar luminosity models used in dynamical supermassive black hole (BH) mass measurements. If uncorrected, dust extinction effects may dominate over other systematic uncertainties when determining the BH mass ($M_\mathrm{BH}$). We expand on a simple dust-attenuation method that treats the circumnuclear disk as a thin dust layer embedded in the galaxy midplane. Using a Multi-Gaussian Expansion, we create a three-dimensional stellar luminosity model to calculate the fractions of stellar light originating in front of and behind the disk along each line of sight. We infer the pixel-by-pixel …

Family Religious Socialization Index: Development And Preliminary Validation, Kaelie Rene Crockett

Theses and Dissertations

A key area of interest for religious scholars is how religious beliefs are passed across generations, or religious socialization. To expand this field of study, a theoretically grounded, validated measure of this construct is needed. This article describes the development and validation of the Family Religious Socialization Index (FRSI), a multi-informant, multidimensional assessment of the processes through which parents socialize religion and faith in their children. Based on Social Cognitive Theory and through a rigorous development and validation process, three subscales were developed to represent the primary processes of religious socialization. The FRSI consists of two parallel scales, a parent …

Identifying The Brain Circuits Involved In Religious Obsessive-Compulsive Disorder, Kiana Bunnell

Theses and Dissertations

Obsessive-compulsive disorder (OCD) is an often-debilitating psychiatric disorder involving a pattern of obsessive thoughts and compensatory compulsions. Symptoms tend to be chronic, leading to substantial emotional burden and significant impairment across multiple domains of daily functioning. Previous research has identified some consistency in the brain regions implicated in OCD. In particular, cortico-striato-thalamo-cortical (CSTC) circuitry has been linked to behavioral features commonly observed in OCD. Moreover, some studies suggest that distinct patterns of brain activation and functional connectivity may be associated with different OCD symptom dimensions, though findings have not been consistent. One symptom dimension of OCD (scrupulosity) is characterized by …

Is “No Change” Really No Change?: A Qualitative Analysis Of Clients With “No Change” On Routine Outcome Monitoring Who Report Improving In Therapy, Audrey Louise Stewart Parker

Theses and Dissertations

Routine outcome monitoring (ROM), the practice of tracking client progress in therapy by administering regular questionnaires to assess functioning, has demonstrated a significant positive effect on psychotherapy outcomes, especially for clients are who not improving as expected. However, some researchers argue the symptom-based measures and outcome classification criteria commonly used in ROM may not represent a complete picture of client change. A recent body of mixed-methods research has investigated these ROM-determined outcome categories to gain insight into client experiences and whether the category and client perception of therapy outcome align. In this investigation, researchers have found significant variety within outcome …

Modifying Lta Zeolites For Reversible Hydrogen Sulfide Capture And Elucidating The Structure Of The Incorporated Metal And Sulfur Ions, Adeyemi D. Ojaide

Theses and Dissertations

Hydrogen sulfide (H2S) is a highly toxic and corrosive gas that poses significant environmental and industrial challenges, particularly within the wastewater treatment and oil and gas sectors. H2S leakage is among the deadliest industrial hazards, highlighting the urgent need for the development of highly efficient, non-corrosive adsorbents. This dissertation provides an in-depth examination of the use of metal-zeolites for H2S capture. We carefully investigate the impact of multiple divalent and one monovalent transition metals on LTA zeolites to optimize H2S removal. While Linde Type A (LTA) zeolites offer a robust structural framework for gas separation, a comprehensive understanding of how …

Co-Opting Modernity: The Semantic Retooling Of Faith At The 1893 World’S Parliament Of Religions, Erik P. Palmer

The Thetean: A Student Journal for Scholarly Historical Writing

The 1893 World’s Parliament of Religions in Chicago served as a high-stakes arena where the boundaries of religious legitimacy were redrawn through the intentional adoption of social science vocabulary. Staged within the Neo-Classical architecture of the White City of the World’s Columbian Exposition, the event was more than a civil gathering; it functioned as a “Museum of Faiths” where religious traditions were curated, categorized, and evaluated against the perceived benchmarks of Western civilization. The physical environment of the Fair, a monument to industrial triumph, was built to display things that worked. The organizers demanded that religions demonstrate they were useful …

Moving Forward, Looking Back: How Mormon Women Sought To Carry Their Polygamous Past Into A Progressive Future Article, Evan Janis

The Thetean: A Student Journal for Scholarly Historical Writing

The influence of woman is fully recognized.” These words, spoken by Emily S. Richards, echoed the shared mission of Utah women at the World’s Congress of Representative Women: to overturn the public perception of them as ignorant, crude, and barbaric. After decades of legal and social campaigns against the so-called “second barbarism” of polygamy, the reputation of Mormon women had been one of its greatest casualties. Cast as too homely to marry a respectable man, too naive to resist deception, and too submissive to think for themselves, the Utah delegation to the 1893 Chicago World’s Fair sought to redefine their …

Letters From The Levant: An Astellian Reading, Tanner Stott

The Thetean: A Student Journal for Scholarly Historical Writing

Among the more startling friendships of early 18th-century London’s literary scene is that of Lady Mary Wortley Montagu and Mary Astell. Their commonalities—remarkable self-education, political activism, and prolific writing—are dwarfed by vast differences of class, politics, and character. Astell, a curiously conservative woman nearly twenty-three years Montagu’s senior, spent her unmarried life squarely in the middle class. Montagu, on the other hand, began her life in England’s loftiest social echelons—the daughter of a Duke, she eloped with untitled Edward only to see him become one of England’s wealthiest men. Montagu lived colorfully with “principles,” according to Lady Irwin, “as corrupt …

Civilizing The Russian Frontier: Ferdinand And Elisabeth Von Wrangell’S Impact On Russian America, Ariel Brown

The Thetean: A Student Journal for Scholarly Historical Writing

In the early 19th century, the Russian colonies in North America struggled due to alcoholism, limited health care, violent attacks from Native tribes, extramarital relations, rat infestations, and weather-induced architectural decay. It is no wonder then that Ferdinand von Wrangell, the sixth governor of Russian America said, “It was our duty or rather we considered it as such, to introduce the concepts of decency and mores to this remote corner of the globe.” He believed his wife Elisabeth would also play a large role in that endeavor, stating, “In the absence of European females our ideas, conventions of civilization and …

From Cotton To Canyons: An Analysis Of The Historic Industries Of Southern Utah, Brielle Beardall

The Thetean: A Student Journal for Scholarly Historical Writing

On October 6, 1861, Brigham Young stood before Latter-day Saints gathered in the Old Salt Lake City Tabernacle and called 300 missionaries on an ambitious undertaking: Over three hundred families would leave their homes and settle in the Utahn southwestern desert; a region that earned the nickname of “Utah’s Dixie” for both its southern location and its punishing heat. Their mission was to cultivate cotton and increase Utahn economic independence from the Confederacy during the American Civil War. Allen Joseph Stout recalled in a personal journal about his experience learning of the call to Southern Utah, “My neighbors reported that …

Narrating The Bucolic South: How Southern Living Reflected And Shaped The South In The 1990s, Krista C. Wright

The Thetean: A Student Journal for Scholarly Historical Writing

In December 1995 at a company Christmas party, previous editor Gary McCalla spoke with Emory Cunningham, sitting president and chair who oversaw the transition from the practical Progressive Farmer to a lifestyle magazine for the “New South.” Looking around the room, Cunningham remarked, “These young people have no idea where we came from.” McCalla recalled a memo he and John Logue, creative director of the magazine, had written in the early days, outlining “what we believed had to be done to save Southern Living.” At that moment, the two noticed the song playing in the background— “History” by Michael …

“Wak[Ing] Up A Sleeping Giant”: Zions Opinion’S Crusade For Independent Governance And Free Speech At Brigham Young University During The 1968–1969 School Year, Joseph Boysen

The Thetean: A Student Journal for Scholarly Historical Writing

In 1968, university and college students across the United States demanded a larger voice in university governance. Sit-ins, rallies, and demonstrations were common, whether for civil rights, free speech, women’s rights, or against the Vietnam war and the draft. For instance, students took over the office of the President of Columbia University to protest the University’s appropriation of land that might have benefited the Black community. In this context, the students at Brigham Young University in Provo, Utah, had the chance to consider how they were going to pursue their own calls for change. Although they did not engage in …

Le Roi Shrinks Before La Nation And La Liberté: Feminine Allegories And The King In French Revolutionary Prints, Jared Cluff

The Thetean: A Student Journal for Scholarly Historical Writing

Printers in the early years of the French Revolution faced an unprecedented problem with new, unprecedented legal flexibility. Though the most cohesive government-coordinated efforts to overturn old symbols and refashion France’s national identity would not come until the Republican period, French engravers in the early years of the Revolution found existing Old Regime symbols and visual codes inadequate tools, so sought “a visual formula for [this] unprecedented historical change.” Furthermore, while the National Assembly did not completely do away with the Old Regime censorship systems that it ostensibly abolished with the Declaration of the Rights of Man and Citizen, printers …

Reshaping Home: Chinese Immigrant Women’S Adaptation And Family Transformation Under Exclusion, Chloe Nicole 零星 Isom

The Thetean: A Student Journal for Scholarly Historical Writing

In 1941, Jew Law Ying arrived at the port of San Francisco with her infant daughter, Bak Heong, seeking admission to join her merchant husband, Yung Hin Sen, in the United States. Upon arrival, immigration officials detained Jew Law Ying and her daughter and required both her and her husband to answer nearly two hundred detailed questions about themselves to prove their identities and relationship. Officials designed these questions to uncover inconsistencies and expose fraudulent relationships, and they were so intricate that, despite their legal and legitimate marriage, Jew Law Ying and Yung Hin Sen had prepared extensively, memorizing answers …

Threads Across The Atlantic: A Dialogue Of Feminist Writings Between Portugal And Cape Verde, Elliana Shillig Venancio

Theses and Dissertations

This thesis examines the feminist literary traditions of Portugal and Cape Verde through a comparative analysis of Ana de Castro Osório’s Infelizes and Dina Salústio’s Mornas eram as noites. Separated by nearly nine decades and an ocean, these two works nonetheless converge in their insistence on women’s autonomy, bodily sovereignty, and resistance to patriarchal structures. Drawing on Hélène Cixous’s theory of écriture féminine and Kimberlé Crenshaw’s framework of intersectionality, this thesis argues that despite the significant differences in time, geography, and socio-political context that separate these authors, powerful threads of feminist consciousness bind their writing together. At the same time, …

Analyzing The Transition From Writing Center Tutor To Graduate Student Instructor, Luci Mackenzie Sullivan

Theses and Dissertations

Writing center tutoring is almost universally considered to be beneficial preparation for graduate student instructors (GSIs) of writing, so much so that many programs require writing center experience as part of their GSI training. Despite various similarities between the roles of tutor and teacher, the precise ways in which writing center experience influences GSIs as teachers remain unclear. This IRB-approved, mixed-methods study builds on previous empirical scholarship on transfer between tutoring and teaching to determine how new GSIs with previous writing center experience integrate practices, knowledge, and dispositions developed in the writing center. My findings echo those of previous studies …

A Graphical Approach To Isospectral Unfoldings, Dallin Seyfried

Theses and Dissertations

Isospectral reductions are mathematical techniques used to shrink a matrix, or a graph, into a smaller, dimensionally reduced form while preserving its spectrum. Simple graphs that share isospectral reductions also share quantum walk properties. As such we further develop the inverse process, isospectral unfoldings, to find graphs that share isospectral reductions. We first prove many conditions relating to isospectral reductions and unfoldings. Afterwards, we define two new unfolding processes: general unfolding which unfolds the graph one vertex at a time, and equitable partition unfolding which excels at larger graph unfolding. In particular, through equitable partition unfolding, we discover many graphs …

Learning, Abstraction, And Creative Search For Interactive Agents, Jonathan Demke

Theses and Dissertations

Artificial intelligence systems are increasingly deployed as autonomous agents that interact directly with complex environments. Ensuring these agents remain reliable, adaptable, and useful presents an ongoing practical challenge. This dissertation studies agent-environment interactions through a progressive lens, examining behavior from foundational training stability and abstraction discovery to adaptation in unpredictable settings and open-ended creative search. The investigation begins by analyzing how hyperparameter settings affect early-stage Deep Q-Network performance, yielding practical guidelines for debugging reinforcement learning implementations. To address the challenge of long-horizon planning, the discovery of temporally extended options is formalized as the Minimum Shortcut Problem, demonstrating how agents can …

Online Parent Group Intervention For Executive Function Skills For Autistic Children And Adolescents, Kathleen Clark

Theses and Dissertations

Executive functioning (EF) skills deficits are prevalent among children and adolescents with autism spectrum disorder (autism) that impacts their academic functioning, social relationships, and families' quality of life. This study aimed to explore an online parent group intervention, to test effectiveness of a 6-week parenting intervention on parenting stress and child's executive functioning (EF) among autism families in rural Utah with limited access to traditional intervention resources. The participants were eight parents from six families of children and adolescents (8-15 years) with clinical diagnosis of autism spectrum disorder and appropriate language abilities for their age. The parents participated in weekly …

Illuminating Hemophilia: Distinguishing Normal And Factor Deficient Plasma Clots Via Brightfield Microscopy And A Convolutional Neural Network, Jason H. Tullis

Undergraduate Honors Theses

When blood vessels are damaged, clots formed by the protein fibrin stabilize platelets and stem active bleeding. Coagulation, the physiological process that forms fibrin clots from blood plasma, hinges on the clotting cascade, a complex network of interacting proteins. These so-called clotting factors help control fibrin polymerization and thereby coagulation. A clotting factor deficiency generally slows coagulation, resulting in bleeding disorders like hemophilia A, B or C. Diagnosing the deficient factor's identity is essential to optimal treatment. Currently, missing factors are determined in reference laboratories via specialized tests. A more accessible test could help streamline the diagnosis process--in this work, …

A Coupled Reaction-Diffusion Model Of Promoting And Suppressing Interactions Among Cancer Hallmarks In Endometrial Cancer, Jeddy Bennett

Theses and Dissertations

Spatial transcriptomics enables the scoring of Cancer Hallmarks at a high resolution across a tissue biopsy, yet current analyses of these data remain largely descriptive, treating each spot as a static, independent observation. This thesis develops a coupled system of advection-diffusion-reaction partial differential equations to model the hallmark landscape as the steady-state solution of an underlying spatial process, and casts the recovery of its physical parameters as a PDE-constrained inverse problem. The framework is implemented in FEniCSx on tissue-specific finite element meshes derived from two endometrial cancer biopsies provided by the Huntsman Cancer Institute, with subdomains, boundary interfaces, and an …

Sand Distribution On Titan And Implications For Sand Transport And Interconnectedness Of Sand Seas, Delaney Rose

Theses and Dissertations

The vast equatorial sand seas of Saturn's moon Titan are of particular interest for understanding surface processes and the budget of organic materials on Titan's surface. Previous studies have described sand dune morphology, transport, collection, and distribution patterns utilizing Cassini Imaging Science Subsystem (ISS), Visual and Infrared Mapping Spectrometer (VIMS), and Synthetic Aperture Radar (SAR) imagery. Studies have also shown evidence both for and against a global interconnected system of sand transport between Titan's major sand seas. This study worked both to create a higher resolution dataset of sand distribution using trimodal thresholding techniques applied to SAR images, as well …

Media Emotion Regulation And Executive Function In Childhood: Associations With Respiratory Sinus Arrhythmia, Lara M. Almeida

Theses and Dissertations

Media emotion regulation (MER), or the use of media to help children manage emotions, may influence children's development by shaping opportunities for practicing self-regulatory skills. Guided by the Dynamic, Relational, Ecological Approach to Media Effects Research (DREAMER) model, this study examined longitudinal associations between MER and executive functioning (EF) in early childhood and explored whether respiratory sinus arrhythmia (RSA), a physiological index of regulation, predicted developmental changes. Participants included 175 parent-child dyads assessed across two annual waves when children were approximately 4 and 5 years old. Structural equation modeling was used to test bidirectional associations between MER and EF while …
