Why Does God Hate Me? A Theistic And Empirical Review Of Attachment To God, Rachel K. Weber

Student Works

General attachment is based on a person’s perceived ability to receive help from their primary caregiver and their perceived worthiness of such help (Bowlby, 1973). This style is separated into four categories that create a paradigm with which future relationships align (Acevedo et al., 2012; Bartholomew & Horowitz, 1991). These four categories are fearful-avoidant, dismissive-avoidant, secure, and anxious-preoccupied (Bartholomew & Horowitz, 1991). This is biologically based and used to ensure an infant’s survival (Bowlby, 1973). These attachment styles are also applicable to one’s relationship to God (Kirkpatrick & Shaver, 1992). Secure attachment to God is indicative of positive religious coping …

FEAT Publications

Pre-print manuscript.

Abstract

This study examines the effect of aging and deterioration on NO_x emissions from heavy-duty diesel trucks (HDDTs) with different emission control technologies, including Engine Control only, exhaust gas recirculation (EGR), and selective catalytic reduction (SCR). In-use tailpipe emissions were measured from 12,023 HDDTs from 13 roadside measurement campaigns conducted in California and Utah between 2008 and 2024. Vehicle registration records and the Environmental Protection Agency’s (EPA) engine certification database were used to identify engine NO_x control technology. At younger ages, SCR-equipped HDDTs generally emitted significantly less NO_x than non-SCR-equipped HDDTs. However, after several years …

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 …

Myths, Risks, And Realities Of Floppy Disk Preservation, Tyler Thorsted, Leontien Talboom, Julianna Barrera-Gomez, Ross Spencer

Faculty Publications

Floppy disks remain vital for accessing early digital collections, yet online forums and blogs circulate many untested myths around these carriers. This paper examines common claims about reading disks; handling, cleaning, storage and media fragility; evaluating them in the context of contemporary workflows. Drawing on practical experience, targeted testing, and collaboration with conservation experts, we distinguish between theoretical risks and real-world workflows. By situating online advice within our own preservation practice, we provided a grounded perspective that helps preservation practitioners navigate legacy media.

Temperature Predictions With Zncuins/Zns Quantum Dots, Reu/Fri Program Physics And Astronomy, Amber Banks

Student Works

For hundreds of years, humans have built thermometers based on the principles of thermal expansion and contraction. In the modern world, there is a need to scale down our thermometers to monitor cellular reactions, both within the human body and within artificial organ chips. Lewis et al. (2020) introduces a nanoscale thermometer based on the thermal expansion of CdTe quantum dots. When ex panded, these dots exhibit systematic changes in photoluminescence (PL) which are recognized by a neural network as an increase in temperature. Our research builds upon the framework of Lewis et al. (2020), testing its feasibility with ZnCuInS/ZnS …

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 …

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 …

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 …

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 …

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, …

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 …

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 …

The Inner Motherhood Penalty: The Impact Of Maternal Self-Stereotyping On Decisions To Apply For High-Status Roles, Jaycelin Eyre

Undergraduate Honors Theses

Stereotype-based discrimination creates obstacles for women's representation in high-status roles, and even more for mothers, who experience a motherhood penalty in hiring, evaluation, and promotion. While literature identifies how maternal stereotypes lead to external discrimination, little is known about how maternal self-stereotyping creates barriers to women's representation in high-status roles. Applying self-categorization theory (SCT) and expectancy theory, this paper examines whether maternal self-stereotyping influences women's willingness to apply for high-status roles through work-family conflict (WFC), which reduces the perceived value (valence) of these roles. In a survey, participants (N = 392) rated their willingness to apply for five jobs varying …
