A Square Peg In A Round Hole: Academic Review And Exhibitions, Cory L. Nimer, Megan E. Frost

Faculty Publications

Academic libraries increasingly use exhibitions as scholarly communication, yet conventional peer-review models rarely account for their collaborative, interdisciplinary nature. Museums and other GLAM institutions have developed standards addressing exhibition goals, audiences, interpretation, attribution, access, and visitor engagement, offering a useful foundation for academic library practice. At Brigham Young University, a library task force examined peer-review models across disciplines and adapted museum standards into a policy for evaluating exhibitions as scholarship in retention and promotion processes. Approved in January 2025, the policy was first applied to By Study and By Faith: 150 Years of BYU, an exhibition developed for the …

Developing A Protocol To Obtain Source Directivity Of Hydroacoustic Transducers In A Water Tank, Benjamin White

Undergraduate Honors Theses

This thesis describes the formulation and application of a methodology designed to obtain source directivity of hydroacoustic transducers in the BYU Underwater Acoustics Laboratory. Piezoelectric transducers are presented, and common methodologies to measure their directivity are reviewed. The schematics of the BYU Underwater Acoustics Lab are explained, including the use of positioning robots to position the source-receiver pair in the measurement chain. The protocol is divided into different configurations comprising various source-receiver orientations. The processes of time gating, calculation of OASPL, and plotting onto directional axes are described. The protocol is tested across four different alternative configurations, including one method …

Parental Perceptions Of Censorship In Utah: Working Paper, Rachel L. Wadham, Dallyn Edmunds

Faculty Publications

The rapid rise of book challenges and removals in U.S. school libraries has increasingly been justified through appeals to parental rights, yet relatively little research has explored what parents themselves believe about censorship and book removal. This exploratory qualitative study examined Utah parents’ perceptions of censorship in school libraries, the kinds of content they believe should be restricted, and the reasoning underlying those beliefs. Using a grounded theory-informed thematic analysis approach, data were collected through a survey of 319 Utah parents with children enrolled in public schools. The survey combined closed-ended and open-ended questions, allowing participants to articulate their views …

God's Will Or Man's? The Power Of Religious Rhetoric In Shaping Wartime Domestic Policy Preferences, Claire E. Brimhall

Undergraduate Honors Theses

How do individuals represent their religious beliefs in the political sphere? Is this impacted by levels of conflict in a given society? In times of war, people of faith often rally behind leaders and policies that diverge from the values upheld by their religious institutions. In fact, in many such cases, religious affiliation and church attendance are among the strongest predictors of support for these political actors.

This thesis examines two such cases where religious voters support policies that contradict the moral teachings of their faith, advancing a theory that a state’s appeals to religion can fundamentally reshape how believers …

Developing An Object Level Understanding Of Sine And Cosine As Ratios And A Coherent Trigonometry, Jeffrey Peter Nair

Theses and Dissertations

Solving right-triangle problems as well as integrating right-triangle and circular trigonometry into a coherent understanding are documented challenges for students. Prior research has deeply investigated students constructing ratio meanings for sine and cosine using a circle-first approach, which then can be extended to right triangles. Also, past work has separately documented distinct meanings that are useful for sine and cosine, in addition to the ratio meaning, including as lengths in a unit circle and coordinate points. This study took these existing ideas and put them together into one possible developmental progression, based on APOS theory, where students can learn length, …

Actionable Hydrologic Data To Information With National Water Model-Based Derived Dataset, Cutting-Edge Data Services, And Agentic Ai System, Sujan Chandra Mondol

Theses and Dissertations

Hydrologic data are the cornerstone of many complex hydrologic research and operational workflows that produce useful hydrologic information for water resources decision-making, flood risk communication, and water availability implications. The National Water Model (NWM) is a valuable source of hydrologic data, particularly for its extended coverage of unmonitored streams and the large-scale continuity of hydrologic processes. Precomputed secondary datasets derived from this simulated data, such as streamflow indices, can improve operational efficiency through thresholding. Disseminating the data through modern technologies, such as application programming interfaces, is required for ready integration into applications. However, if extraction requires an intermediate service, there …

"Tithing Is An Insurance Premium": A Framing Analysis Of Speaker Innovation And Diachronic Trends In Latter-Day Saint Religious Discourse, Reid Empey

Theses and Dissertations

Religious language relies on shared metaphor and frames that contextualize religious experience and practice. Current approaches to frame semantics (Fillmore 1982) and cognitive metaphor (Lakoff & Johnson 1980) lend important insight into religious language, particularly in describing the role that figurative language serves in a religious speech community. However, a vital component of many religious speech communities is the presence of and engagement with a scriptural canon, which often contains metaphorical and framing language that religious speakers can directly reference. Yet, past conceptualizations of speech communities have not accounted for this engagement with a shared canon. To illustrate the role …

Synthetic Strategies For Bioactive Peptides: From Aggregation Inhibitors To The Total Synthesis Of Tunicyclin C, Stephanie Graciela Garcia Morin

Theses and Dissertations

In Alzheimer's disease (AD), a brain protein called "tau" abnormally clumps and forms neurofibrillary tangles (NFTs), causing damage to brain cells. Ac-PHF6-NH2 is a hexapeptide segment of tau protein that plays a dominant role in tau aggregation and is used as a model to design tau protein aggregation inhibitors. In this research we synthesized four dehydroamino acid (□AA) containing PHF6 analogues with △Abu (derived from L-threonine) and △Val (derived from □-OH-Valine) at position 2 or 3 via dehydrations or azlactone ring-openings as key reactions. We evaluated their proteolytic resistance, ability to inhibit aggregation of PHF6, and impact on the morphology …

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 …

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 …

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 …

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 …

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 …

Physical Activity, Trauma, And Posttraumatic Stress: The Indirect Role Of Exercise Addiction, Anastasiia Rozumna

Theses and Dissertations

Exercise is often conceptualized as a protective factor for mental health, including for individuals exposed to trauma. However, less is known about whether exercise may relate to posttraumatic stress symptoms differently when it is accompanied by compulsive or addictive features. The present study examined whether volume and intensity of physical activity were associated with posttraumatic stress symptom severity indirectly through exercise addiction symptoms. This secondary cross-sectional analysis included 557 adults living in the United States who reported regular participation in sport or physical activity. Participants completed self-report measures of physical activity behavior, exercise addiction symptoms, trauma exposure, and posttraumatic stress …

A Systematic Review Of Posttraumatic Stress Disorder Among Hispanic Immigrants In The United States, Rashel Acireale

Theses and Dissertations

This study systematically reviews the literature on posttraumatic stress disorder (PTSD) among Hispanic immigrants in the United States, a population exposed to cumulative trauma across the migration process. Stressors may occur before, during, and after migration and include violence, family separation, dangerous travel conditions, discrimination, and fear of deportation. Despite these risks, findings on PTSD prevalence remain mixed, and Hispanic immigrants are underrepresented in clinical research and culturally informed interventions. This review examines sample representation, types and timing of trauma, PTSD measurement approaches, and the inclusion of cultural and contextual factors such as acculturation and immigration-related stress. It also evaluates …

Depictions Of Girls With Adhd In Contemporary Picturebooks: A Critical Content Analysis, Madison Briann Smith

Theses and Dissertations

This study examines how girls with ADHD are depicted in contemporary picturebooks through the theoretical framework of critical disability studies (CDS). While research has increasingly explored disability representation in children's literature, depictions of girls with ADHD remain underexamined despite the ways in which ADHD manifests in female populations and the historical underdiagnosis of females with the condition. Using critical content analysis (CCA), six contemporary picturebooks featuring female protagonists with ADHD were analyzed for their visual and textual representations of neurodiversity. Findings were organized into two overarching themes: strength-based and deficit-based depictions. Strength-based portrayals emphasized creativity, identity formation through adult mentors, …

Properties Of Enjoyable Mathematical Contexts From The Student Perspective, Emilie Nadine Hendrickson

Theses and Dissertations

Researchers continue to grapple with how to meaningfully engage students in mathematical content. Many students report disengagement due to perceptions that mathematics is difficult, irrelevant, boring, or anxiety-inducing. This study sought to understand how students interpret and respond to different mathematical problem contexts, with particular attention to the reasons students describe certain problems as enjoyable or unenjoyable. Using semi-structured interviews, this research examined student responses to a variety of mathematical problem types primarily across affective engagement. Students reflected on specific problem contexts and explained which features supported or hindered their enjoyment and engagement. Students described that contexts were enjoyable have …
