Comparing The Effectiveness Of Telehealth Training For Parents Using “Help Is In Your Hands”: Joint Attention And Mands, Vivian Desiree Cortez Dominguez

Theses and Dissertations

This study aimed to compare the effects of remote parent training for parents of autistic children in Peru, ages 2-4 years old. Using the Spanish version of the digital program called “Help is in Your Hands” (Rogers & Stahmer, 2026; 3C Institute, 2026), three mothers were trained on how to support their child's ability to participate in joint attention and mand. Autism is a condition in which children present with challenges in engaging with others, such as sharing joint attention and using mands. Several evidence-based trainings target these difficulties. However, accessing these trainings can be expensive and time-consuming. In less-developed …

Shame On You! The Socialization Of Self-Conscious Emotions In Early Childhood, Ashton K. Allen

Theses and Dissertations

This study examined how parents and children discuss self-conscious emotions across early childhood. Self-conscious emotions such as shame, guilt, embarrassment, awe, and pride play a critical role in children's social and emotional development. Although prior research has demonstrated links between parent and child emotion talk about basic emotions such as happiness, anger, disgust, fear, sadness, less is known about how parents and children talk about self-conscious emotions. Participants for the current study were 247 parent-child dyads. The dyads completed a wordless storybook task designed to elicit discussion of five self-conscious emotions (shame, guilt, embarrassment, awe, and pride) annually across three …

Utah Secondary English Language Arts Teachers And The Use Of Body Diverse Young Adult Literature, Katy Johnson Bigham

Theses and Dissertations

Representation in young adult (YA) literature has expanded significantly in recent years, but body size diversity - specifically the inclusion of fat protagonists - is still minimal and understudied in secondary English language arts (ELA) classrooms. Research shows that diverse literature plays a crucial role in helping students see themselves and other reflected in the texts they read, as shown in the metaphor of literature as "windows, mirrors, and sliding glass doors" (Bishop, 1990). So how does this apply to the representation of body size diversity in the ELA classroom? This study explores how secondary ELA teachers in Utah perceive …

"A Politics Of Its Own": Reading Adelaide Procter's Poetry In The Context Of The English Woman's Journal, Rachel Diane Gouff

Theses and Dissertations

Victorian poet Adelaide Anne Procter, a devout Catholic and a nineteenth-century feminist and social activist, was hugely popular in her lifetime for her devotional and sentimental poetry. However, scholars who have looked closely at her work have recognized that her poetry contains moments of tension that suggest they may be more than they appear on the surface. Such tensions and ironies are often glossed over or misread by readers whose expectations of Christian devotional messaging and domestic sentiment overshadow the contradictions. In this paper, I propose that one of the most effective ways to more fully understand the nuance and …

Subversive Speculative Theology In Women's Stories From The Mormon Home Literature Movement, Rachel Meibos Helps

Theses and Dissertations

In the 1910s, Mormon women used sentimental speculative fiction published in official Relief Society Magazine to engage theological questions often reserved for male ecclesiastical authority. This paper examines three short stories: Edna Coray's "A Quitter–Almost." (1918), Lucy May Green's "A Whiff of Ether" (1919), and Laura Jenkins's "Beyond the Portals" (1916), each of which depicts a woman's encounter with the spirit world at the moment of death or near-death. Drawing on the Mormon Home Literature movement and the broader tradition of sentimental fiction as political and moral discourse, I argue that these authors used narrative to fill gaps in official …

Tracing Microplastics From Polymer-Coated Urea: Urban To Agricultural Pathways And Environmental Fate, Caden Joseph Seely

Theses and Dissertations

Polymer-coated urea (PCU) is widely used as a slow-release nitrogen (N) fertilizer because it improves N use efficiency and reduces losses through leaching, denitrification, and volatilization. However, the polymer coating raises concerns about potential microplastic (MP) transport to surface waters following fertilizer application. This thesis evaluates the off-site transport of MPs and associated nutrient and sediment losses from PCU in both urban landscape and agricultural systems. In the urban landscape study, treatments included sod, mulched beds, and water-efficient ground cover receiving uncoated urea, PCU, or liquid slow-release N at 225 kg N ha⁻¹ (with reduced rates for beds and ground …

Toward A Horizonal "I": The Infinite Subject In William Wordsworth's The Prelude, Gabriella Lee Schwartz

Theses and Dissertations

In an 1805 letter to Sir George Beaumont describing his autobiographical poem The Prelude, William Wordsworth remarked that it was "a thing unprecedented in literary history that a man should talk so much about himself." Since then, critics have only affirmed Wordsworth's reputation as a poet, if not the poet, of selfhood and consciousness. Perhaps the most renowned scholarship on Wordsworthian subjectivity was produced by the so-called "Yale School" of the late twentieth century, as J. Hillis Miller, Harold Bloom, Geoffrey Hartman, and Paul de Man all published influential works on the topic. The latter two staked out stances on …

Evaluating Measurement Invariance Frameworks: A Comparison Of Mg-Cfa, Alignment Optimization, & Bayesian Approximate Measurement Invariance Using The Brigham Young University Counseling And Psychological Services Client Satisfaction Survey, Heidi Lula Lindsey

Theses and Dissertations

Researchers must establish measurement invariance (MI) before comparing latent constructs across groups to ensure construct validity. However, traditional multi-group confirmatory factor analysis (MG-CFA) may impose overly strict equality constraints in applied settings. Alternative MI frameworks are less familiar to researchers, which limits their use. This study compares MG-CFA, alignment optimization (AO), and Bayesian approximate measurement invariance (BAMI) using archival data from the Brigham Young University Counseling and Psychological Services Client Satisfaction Survey (N = 1,278). Participants completed an exit survey after receiving individual (n = 1,063), couple (n = 83), or group (n = 132) therapy, answering 16 five-point Likert …

Biophysical Insights Into A Cryptic, Hydrophobic Binding Site On Pcna, Alexis Dispensa

Theses and Dissertations

Proteins are dynamic molecules whose functional landscapes extend beyond static structural representations. Transient cryptic pockets (buried cavities that emerge through protein motion) represent underexplored targets for allosteric regulation and drug discovery. General anesthetics are small, lipophilic, weakly polar molecules that are well suited to partition into such hydrophobic sites. In this work, environment-sensitive fluorescence, photoaffinity labeling, mass spectrometry, mutational analysis, and microsecond molecular dynamics simulations were integrated to discover and characterize a cryptic, highly apolar binding site within the hydrophobic core of human proliferating cell nuclear antigen (PCNA), a central scaffold in DNA replication and repair. Using the solvatochromic fluorescent …

Family Processes As A Protective Factor Between Adverse Childhood Experiences And Adolescent Delinquency, Tessa Johnson

Theses and Dissertations

This study explores whether family processes (i.e., parental attachment and parental discipline/monitoring) serve as protective factors between the relationship of adverse childhood experiences (ACEs) and adolescent delinquency. Prior research has established an association between ACEs and many negative life outcomes, including delinquent behavior, while strong parental attachment and parental discipline/monitoring are linked to lower rates of delinquency. However, the interplay of these three factors has been understudied. Drawing on data from the 2024 Florida Youth Substance Abuse Survey (FYSAS) (N=22,016), this study examines the relationship between ACEs, family processes, and delinquency using negative binomial regression models. Results indicate that parental …

Hybrid Bermudagrass Dormancy Management In A Cool-Season Climate, Clarissa H. Peterson

Theses and Dissertations

Hybrid bermudagrass (Cynodon dactylon [L.] Pers. × C. transvaalensis Burtt Davy) (HBG) is a water efficient warm-season turfgrass increasingly adopted in cool-season and semi-arid regions due to climate change and the demand for reduced irrigation inputs. However, prolonged winter dormancy limits its visual quality (verdure) and seasonal performance. This thesis evaluated multiple management strategies to modify dormancy dynamics and improve off-season turf quality in a cool-season environment. Field experiments assessed the effects of growth covers, fertilizers, colorants, surfactants, organic acids, and overseeding with cool-season species on HBG dormancy over two seasons. Dormancy responses were quantified using normalized difference vegetation index …

Real-Time Data Collection System For Low-Cost Diesel Emissions Monitoring, Zachary Driskill

Theses and Dissertations

Diesel trucks are a major source of pollutants, including particulate matter (PM) and NO$_x$. Roadside emissions monitoring can identify high-emitting diesel vehicles, but conventional sensing systems rely on expensive, complex sensing instruments that limit widespread deployment. Low-cost sensors offer increased scalability due to their small size, low cost, and low power consumption, but they have lower accuracy and slower response time. This thesis presents the design and evaluation of a low-cost roadside emissions monitoring system, establishing the foundation for a scalable and widely deployable alternative. We apply machine learning calibration to roadside emission monitoring to improve the usability of low-cost …

Practical, Scalable, And Cost-Effective Nanolc-Ms Workflow For Single-Cell Proteomics, Siqi Huang

Theses and Dissertations

Single-cell proteomics provides a novel research strategy for decoding cellular heterogeneity, revealing the molecular mechanisms of rare cell subpopulations, and studying the dynamic responses of cells to external stimuli. However, compared to transcriptomics, single-cell proteomics faces even more challenging technical challenges: extremely low protein amount in single cells, wide dynamic range, significant adsorptive losses during sample preparation, and the complex matrix and trace sample injection demanding extremely high stability and sensitivity from the separation and detection systems. Mass spectrometry-based bottom-up proteomics has become an important tool for analyzing complex biological systems, and nano-flow liquid chromatography-mass spectrometry (nanoLC-MS) exhibits unique advantages …

"Deep In The Trenches": A Multi-Perspective Interpretive Phenomenological Analysis Of Student Mothers Navigating The Hidden Realities Of Postpartum Anxiety, Rhonda Harris

Theses and Dissertations

Despite availability of effective treatments women with postpartum anxiety (PPA) commonly go untreated because of barriers to care. Student mothers are a particularly vulnerable subgroup of women as they tend to be younger, are less likely to be married, and have lower incomes than non-student mothers. As anxiety rates in college women are higher than the general population and higher than college men, student mothers are at high risk of the adverse effects of untreated PPA. There is a paucity of existing literature about student mothers and mental health. The aim of the current study is to understand the help-seeking …

Transcriptomic Analysis Of Xeroderma Pigmentosum Group C Skin Samples, Austen N. Gleave

Theses and Dissertations

Xeroderma Pigmentosum is a rare genetic disorder caused by defective DNA damage repair enzymes. This condition results in an increased risk of developing skin cancer and other symptoms in those affected. In this thesis, we examined the effects of Xeroderma Pigmentosum on gene expression in patient skin biopsy samples. To accomplish this, we utilized statistical analysis of spatial transcriptomic and single-cell RNA sequencing techniques to discover differences between patient and heterozygous carrier skin samples. We found that the skin samples from Xeroderma Pigmentosum patients showed elevated levels of inflammation, immune activation, and cellular stress, while the carrier skin samples leaned …

No Principal Left Alone: Exploring Elementary Principals' Relationships With Their Full-Time Assistant Principals, Shauna Worthington

Theses and Dissertations

Elementary school principals are often the only administrator in their building; therefore they are left to face the adverse circumstances of their job without the support of an administrative colleague at their school. However, U.S. nationwide data suggests that school districts are more frequently hiring elementary assistant principals. This paper explores perceptions of elementary principals about the nature and dynamic of their relationships with their full-time assistant principals, including accompanying benefits and challenges. This qualitative inquiry utilizes an exploratory, descriptive, phenomenological approach and features the results of in-depth interviews with 20 elementary school principals in two large suburban public school …

Fallow Ground, Eli Kerns

Theses and Dissertations

Fallow Ground refers to the agricultural practice of intentionally leaving a field unseeded for a year or more in order to restore fertility and interrupt cycles of depletion. Although fallowing is a beneficial and necessary practice, the term has also come to signify waste or a lack of productivity. This double meaning is central to the work, reflecting a central contradiction: that withdrawal can be as vital as effort, and that rest, like labor, can function as a deliberate and sustaining act. The question I explore in this work is how to organize, understand, and live with these contradictions. Through …

Empirical Benchmarks For Interpreting Effect Sizes In Violent Crime Interventions, Kohta James Matsukawa Hansen

Theses and Dissertations

Criminal justice researchers apply Cohen’s (1988) benchmarks to classify effect sizes as small, medium, or large, despite these standards never being meant for broad, decontextualized use (Cohen, 1988; Gies et al., 2024; Goulet-Pelletier & Cousineau, 2018; Lakens, 2013; Milner et al., 2023). Repeatedly doing so may weaken statistical validity, distort findings, and impede effective policymaking. This study introduces the first effect size benchmarks specifically designed for violent crime interventions.

Using a quasi-meta-analysis framework, 1,605 effect sizes from 104 violent crime intervention studies from the CrimeSolutions clearinghouse were converted to Cohen’s d. Three new discrete benchmarking methods were created using a …

Development Of Hypergraph Based Deep Neural Framework For Precise Cancer Subtyping And Meta Visualization, Pooja G Ms

Theses and Dissertations

Accurate Cancer Subtyping is a cornerstone of modern oncology essential for effective diagnosis and guiding personalized treatment. Histopathological Images (HIs) which capture the microscopic structure of tissues are widely used for cancer detection and subtyping. Even though deep learning has made significant advances, existing HI based subtyping methods often focus on specific cancer types, lacking a generic framework.

A unified framework that can classify multiple cancers with high specificity is desperately needed. In response to these limitations, this thesis proposes a robust multi-cancer, multi-class subtyping framework called DSHGNet (Depthwise Separable Hypergraph Convolutional Neural Network) which integrates Depthwise Separable Convolutional Neural …

Combinatorial Therapeutic Strategies To Combat Multidrug-Resistant Acinetobacter Baumannii, Tope A. Aderibigbe

Theses and Dissertations

Acinetobacter baumannii is an opportunistic Gram-negative pathogen that poses a significant global health threat due to its remarkable ability to acquire multidrug (MDR) and extensively drug-resistant (XDR) phenotypes. Therapeutic failures are increasingly common as strains develop resistance to nearly all available antibiotics, including carbapenems, polymyxins, and tigecycline, leaving clinicians with limited treatment options. This study aimed to investigate combinatorial therapeutic approaches capable of revitalizing antibiotic efficacy against MDR/XDR A. baumannii clinical isolates. We evaluated the synergistic potential of durlobactam-sulbactam in combination with twelve commonly used antibiotics, including amikacin, rifampin, tobramycin, tigecycline, cefiderocol, and others.
