Brief Reviews Of Books And Products: Theses On The Metaphors Of Digital-Textual History, David Advent May 2026

Brief Reviews Of Books And Products: Theses On The Metaphors Of Digital-Textual History, David Advent

Library Faculty & Staff Publications

Theses on the Metaphors of Digital-Textual History is an exploration of seven key metaphors that Martin Paul Eve, Professor of Literature, Technology, and Publishing at Birkbeck College, University of London, argues have structured our cultural and linguistic understandings of the world around us. Eve organizes the book around eight chapters (“theses”), with each metaphor comprising a separate chapter. The theses are connected thematically in pairs, save for the closing chapter. Eve decodes each metaphor into its basic elements and interweaves the complex digital and textual histories behind each metaphor. Overwhelmingly, Eve wants readers to recognize how striking the parallels are …

Working Alliance And Subjective Engagement With A Digital Avatar Cbt Platform (Ritch®Cbt): Comparing Young Adults With And Without Co-Occurring Substance Use And Depression, Victoria Pezzino, Cassandra Berbary, Courtney Mckinney, Celeste Sangiorgio, Emi Moriuchi, Korena S. Klimczak, Robert Kay Cooper Jr., Wonkyung Kniffen, Maya Hareli, Cory Crane, Caroline J. Easton

Psychology Student Research

Digital mental health interventions (DMHIs) can help bridge treatment gaps experienced by young adults with co-occurring substance misuse and depression. However, it remains unclear whether engagement with these interventions differs for young adults with co-occurring conditions compared to those experiencing substance misuse or depression alone. To investigate this issue, we assessed working alliance and subjective engagement with a digital avatar-assisted cognitive-behavioral therapy (CBT) treatment platform (RITch®CBT), comparing young adults with substance use, depression, and the co-occurrence of the two. A secondary data analysis was conducted on a sample of 99 young adults aged 18–28 years who presented at …

Seven Top Opportunities For Utah Girls And Women: A 2026 Update, April Townsend, Susan R. Madsen

Marketing and Strategy Faculty Publications

Decades of scholarship—within Utah and across national and global contexts—demonstrate that expanding opportunities for girls and women begins with understanding where those opportunities already exist and where they can be strengthened. Building this awareness creates the foundation for strategic, high‑impact action. In Utah, the Utah Women & Leadership Project (UWLP) plays a central role in this work, producing hundreds of research reports that surface ongoing challenges1 while simultaneously highlighting the conditions, possibilities, and pathways that support girls, women, and families.


Evidence-Based Practice: A Framework For Behavior Analytic Training And Supervision, Audrey N. Hoffmann, Andrea Q. Hoang May 2026

Evidence-Based Practice: A Framework For Behavior Analytic Training And Supervision, Audrey N. Hoffmann, Andrea Q. Hoang

Special Education and Rehabilitation Counseling Faculty Publications

As the field of applied behavior analysis (ABA) grows, there is a need for effective and high-quality fieldwork supervision to prepare a growing workforce. This paper proposes the use of evidence-based practice (EBP) as a decision-making framework in the training of behavior analysts, emphasizing its potential to enhance the skillsets of practitioners. EBP involves integrating the best available evidence, client values, and professional judgment to guide clinical decisions. While the use of EBP as a clinical decision-making framework has grown in other helping professions, its application in the field of ABA remains limited. This paper proposes competencies for EBP decision-making …

Developing Self-Determination Through Physical Activity Courses In Inclusive Post-Secondary Education Programs, Shannon P. Zimmerman, Samantha Ross-Cypcar, Peter R. Giacobbi, Lesley Cottrell, Emily Murphy, Andrea Taliaferro, Jeanette Garcia

Developmental Disabilities Network Journal

Adults with intellectual and developmental disabilities (IDD) often experience low physical activity levels, with only 23% meeting recommended guidelines, increasing their risk for secondary health conditions. Inclusive Post-Secondary Education (IPSE) programs in the U.S. present an opportunity for physical activity promotion. This study examined physical activity strategies across a national sample of IPSE programs (n = 27) using a sequential mixed-method approach, including surveys and follow-up interviews, focusing on alignment with Self-Determination Theory (SDT). While 70.37% of programs offered formalized physical activity courses, all promoted physical activity informally. Common practices included peer mentorship (96.3% of programs), goal setting (100%), and …


Measuring Disability Prevalence In Healthcare: A Study Comparing Two Disability Measures, Kristen L. Milefchik, Rhonda K. Dailey, Sharon Milberger May 2026

Measuring Disability Prevalence In Healthcare: A Study Comparing Two Disability Measures, Kristen L. Milefchik, Rhonda K. Dailey, Sharon Milberger

Developmental Disabilities Network Journal

People with disabilities experience significant health disparities and interventions are needed to address them. Measuring disability prevalence is an essential aspect of designing effective, data-driven healthcare strategies. Accurately measuring disability prevalence is challenging given disability is a complex phenomenon, with biological, social, environmental, and cultural components. Previous studies have compared a variety of disability status measurements and found that measurements were incongruent with each other. This study examines the concordance between disability status using two different measures: the nationally recognized American Community Survey (ACS-6) functional difficulty questions and one disability identity question. We used data from 3,621 adult patients participating …


Utahns Prefer State Management Of Public Lands, Casey Trout, Michaelann Nelson, Jessica D. Ulrich-Schad May 2026

Utahns Prefer State Management Of Public Lands, Casey Trout, Michaelann Nelson, Jessica D. Ulrich-Schad

Utah People and Environment Poll (UPEP)

In August 2024 the Utah Attorney General’s Office filed a Bill of Complaint challenging the federal government’s ownership of 18.5 million acres of unappropriated land within the state’s borders (1). The state intends the lawsuit to pave the way for eventual transfer of the land to state ownership (2). The Legislature allocated roughly $20 million to the lawsuit as well as a marketing campaign to increase public support for efforts to transfer public lands out of federal ownership. Of that, over $500,000 was spent on attorney’s fees related to the case and over $2.6 million was allocated to a marketing …


Effects Of Beaver Dams On Components Of Riverscape Health And Biodiversity In The Great Basin, Cashe C. Rasmussen May 2026

Effects Of Beaver Dams On Components Of Riverscape Health And Biodiversity In The Great Basin, Cashe C. Rasmussen

All Graduate Theses and Dissertations, Fall 2023 to Present

Networks of rivers and their floodplains (i.e., low-lying areas adjacent to rivers and streams that could plausibly flood) have been degraded, reducing the availability of freshwater and habitat for people and wildlife. Therefore, land managers are pursuing cost-effective restoration strategies, including partnering with beavers (Castor canadensis), to promote the health of these ecosystems and associated benefits. However, our understanding of beaver-mediated restoration benefits remains incomplete. Here, we compared locations along streams with and without beaver dams to measure the benefits of beavers in the Great Basin of the Western United States. We measured the effects of beaver dams …

Faith And Doubt: Exploring How We Interpret The World, Amber Mccuen

All Graduate Theses and Dissertations, Fall 2023 to Present

This collection of four fictional short stories explores questions of belief—and practice of belief—in four separate contexts. The first story, “Little Marie,” follows a young girl who’s made her own system of belief created by correlation. The second story, “Last Days,” sees a woman return to her childhood home which has been overcome by the hoarding habits of her paranoid, fundamentalist Christian mother. The third story, “Graduation,” takes place at a divinity school graduation and explores the strength of both social influence and unspoken rules within closed groups. The final story, “Away From the Ninety and Nine,” follows a cult …


Development Of A Novel Method For Simultaneously Testing Multiple Specimens To Evaluate Tension-Tension Fatigue Life, Mehedi Hasan Mahfuz May 2026

Development Of A Novel Method For Simultaneously Testing Multiple Specimens To Evaluate Tension-Tension Fatigue Life, Mehedi Hasan Mahfuz

All Graduate Theses and Dissertations, Fall 2023 to Present

The aim of this study is to develop a novel method for rapidly evaluating the tension–tension fatigue life of metals. Fatigue failure, which occurs when materials gradually weaken and fracture under repeated loading, is a critical concern in designing safe and reliable structures such as airplanes, cars, and bridges. Traditional fatigue testing methods are slow, costly, and typically limited to one specimen at a time. To address this, a high-throughput testing method was developed that allows multiple small-scale specimens to be tested simultaneously while following international testing standards. Using stainless steel sub-sized specimens scaled at 1:5 relative to the ASTM …


Leveraging The Iron Oxide Archive Of Mineralization, Deformation, And Exhumation Across Geologic Time, Jordan L. Jensen May 2026

Leveraging The Iron Oxide Archive Of Mineralization, Deformation, And Exhumation Across Geologic Time, Jordan L. Jensen

All Graduate Theses and Dissertations, Fall 2023 to Present

The iron oxide mineral hematite commonly forms from groundwater near Earth’s surface and can preserve a history of fluid flow, fault slip, and landscape evolution. This record can be decoded using (U-Th)/He thermochronology, a dating method based on the temperature-sensitive ingrowth of helium from uranium and thorium decay. Because later heating and natural variation in hematite crystals can produce ambiguous (U-Th)/He results, I integrate dating with tools that reveal differences in hematite chemistry and textures. I apply these techniques to two distinct settings: ancient granitic rocks in Colorado and an active fault zone in the southern San Andreas fault (SSAF) …


A Dyadic Mixed Methods Study Of An Online Asynchronous Acceptance And Commitment Therapy Intervention For Individuals Diagnosed With Dementia And Their Caregivers, Gavin Brendan Green May 2026

All Graduate Theses and Dissertations, Fall 2023 to Present

A dementia diagnosis can be overwhelming for both the person diagnosed and the people who care for them. Many experience stress, uncertainty, and emotional strain, yet most support programs require significant time and are difficult to access. This study examined a brief, online program called the Compassion Compass, designed to provide early emotional support for both individuals living with dementia and their caregivers.

The program is based on Acceptance and Commitment Therapy and can be completed in about 30–45 minutes. It focuses on helping individuals notice difficult thoughts and emotions, reconnect with what matters to them, and take small, …


Where Were Women?: Women In The United States Intelligence Organizations From The Office Of Strategic Services To The Central Intelligence Agency, Madison Harris May 2026

Where Were Women?: Women In The United States Intelligence Organizations From The Office Of Strategic Services To The Central Intelligence Agency, Madison Harris

All Graduate Theses and Dissertations, Fall 2023 to Present

United States intelligence historians have largely neglected the importance of women’s intelligence labor as well as the centralized intelligence organizations that existed from World War II to the early years of the Central Intelligence Agency (CIA) – including the Office of Strategic Services (OSS), Strategic Service Unit (SSU), and Central Intelligence Group (CIG). While assumptions about women in intelligence work during this period are usually drawn from stereotypical portrayals in popular media, such as books and movies, this thesis utilized statistical data and other agency sources to build a broader understanding of women’s actual labor.

This thesis demonstrates that women …


Developing Training And Streamlining Training Management Process For Smithfield Fire Department Employees In Aha, Naemt, And Aap Certifications, Michael Christopher Popa Ii May 2026

Developing Training And Streamlining Training Management Process For Smithfield Fire Department Employees In Aha, Naemt, And Aap Certifications, Michael Christopher Popa Ii

Undergraduate Honors Capstone Projects

The rapid operational expansion of the Smithfield Fire Department and EMS (SFD)—marked by a 300% increase in call volume and a transition to a fully professional, independent paramedic service—exposed critical systemic inefficiencies in clinical preparedness and personnel credentialing. This project addresses the "HALO Paradox," wherein high-acuity, low-occurrence emergencies require expert-level proficiency that cannot be maintained through call volume alone. Historically, the agency relied on fragmented, external continuing education (CE) that incurred high financial costs, lacked equipment standardization, and created administrative bottlenecks during biannual recertification cycles. The central objective of this capstone was to engineer a sustainable, in-house training infrastructure that …


Evidence-Based Practice In Speech-Language Pathology: Creating Effective Therapy Materials, Avalee Dunkley May 2026

Evidence-Based Practice In Speech-Language Pathology: Creating Effective Therapy Materials, Avalee Dunkley

Undergraduate Honors Capstone Projects

Evidence-based practice is a fairly new topic in speech-language pathology, gaining traction among professionals in the field in the last twenty years. Evidence-based practice is the integration of high-quality research, patient cultural and social values, and clinician expertise to treat a patient. Patients are more likely to progress when these three factors are combined. This paper explores four areas of speech-language pathology that are commonly treated in school-aged children: speech sound disorders, language disorders, social communication disorders, and the use of augmentative and alternative communication. Each section gives a summary of the disorder and how the disorder can be treated …

Undergraduate Honors Capstone Projects

The purpose of this project is to design and implement a student-led engineering mentorship program directed by the members of the Utah Gamma Chapter of Tau Beta Pi on the Utah State University (USU) Logan campus. Retention data show that many undergraduate students who start engineering programs change their degree before graduation due to academic and social challenges that may be mitigated by the support of a peer mentor. The Tau Beta Pi Engineering Mentorship Program selects and trains upperclassman mentors to effectively mentor underclassman engineering students.

The design of the mentorship program is an application of backward design, where …


A Look Through The Bluest Eye: Intersectionality, Identity & The Role Of Fiction, Sydney Foster May 2026

A Look Through The Bluest Eye: Intersectionality, Identity & The Role Of Fiction, Sydney Foster

Undergraduate Honors Capstone Projects

Since its coinage in 1989, the idea of intersectionality has persisted academic research in understanding how a person is treated and what experiences they are subjected to, specifically those belonging to marginalized groups. My theory is that a person’s intersectionality is the vehicle which leads to their experiences, which when totaled, comprise a person’s identity. This project focuses specifically on the treatment of Black women and girls, the academic research and first-hand accounts that support the existence of the perpetual adultification, dehumanization, and sexualization of these individuals, and how these phenomena increase Black women and girls’ risk for maltreatment, specifically …


Self-Efficacy Through The Use Of Ai-Video Simulations And Video Feedback (Goreact) For Medical Interpreting Training, Ricardo Tienda-Pérez May 2026

Self-Efficacy Through The Use Of Ai-Video Simulations And Video Feedback (Goreact) For Medical Interpreting Training, Ricardo Tienda-Pérez

Undergraduate Honors Capstone Projects

In today’s diverse and modern healthcare systems, medical interpreters play a critical role in clinical safety and quality care. However, a pedagogical gap exists between classroom vocabulary mastery and the self-advocacy skills required in real-world clinical settings. This research evaluates the impact of AI-generated video simulations and GoReact’s time-coded feedback on the self-efficacy and self-advocacy of student interpreters enrolled in the Spanish Medical Interpreting Training course (SPAN 4081) at Utah State University’s Logan campus – as part of the Spanish Medical Interpretation & Translation certificate program during the Spring 2026 semester. By utilizing a mixed-methods research design, this study collected …


Nutrition Teaching Methods In Communities, Emery Fayth Rowles May 2026

Nutrition Teaching Methods In Communities, Emery Fayth Rowles

Undergraduate Honors Capstone Projects

Community is a vital part of non-formal education. A sense of, longing for, and responsibility towards community draws individuals to participate in local services and classes. Community has been shown to have positive impacts on learning, self efficacy, and health.

Many of the techniques used in education mirror techniques used in building community—such as the use of small group discussions and cultural sensitivity—but with distinct differences in mindset. Most educational approaches see the acquisition and use of knowledge as the key purpose of the program and evaluate participants on an individual basis. This approach makes sense for programs meant to …


Learning About The Direct Experiences Of Very Young Children With Hearing Loss: A Feasibility Study, Jenni M. Funk May 2026

Learning About The Direct Experiences Of Very Young Children With Hearing Loss: A Feasibility Study, Jenni M. Funk

Undergraduate Honors Capstone Projects

We aimed to explore the feasibility of employing a developmentally appropriate, modified puppet interview method to elicit thoughts and perspectives directly from very young children (ages 3 to 6 years old) who are deaf or hard-of-hearing. Little is known about the direct experiences of children with hearing loss, making it difficult to improve care. In our field of speech and hearing sciences, there is no current method of gathering direct experiences of young children and placing them at the center of care. We proposed that researchers may be able to learn about the direct experiences of very young children who …


Desert Deep: The Great Salt Lake's Evanesce And The Gravity Of Recovery, Avery Truman May 2026

Desert Deep: The Great Salt Lake's Evanesce And The Gravity Of Recovery, Avery Truman

Undergraduate Honors Capstone Projects

The Great Salt Lake has been shrinking since the mid-19th century for several reasons, primarily due to a higher evaporation rate caused by climate change and water diversion from the Bear, Weber, and Jordan rivers. This problem will cause mass ecosystem destruction, release toxic chemicals into the air, and strand migrating birds. As an environmental studies and geography major, I’ve spent a lot of time learning about the Great Salt Lake in my courses. I decided to write Desert Deep, a series of essays, after I took my first creative nonfiction writing class. The goal was to tell the …

This project focused on creating online resources for using the statistical software package R in an introductory statistics course at Utah State University. The goal was to make R more accessible, user-friendly, and engaging for learners. To do this, existing written materials were moved to a new section of an online website called Stats Stuff. Then interactive features were added such as step-by-step video tutorials, real datasets, and an embedded coding tool. These resources have been in use for the past four years and have helped students build confidence and enhance their statistical learning experience.


Discovering Strategic Behaviors In The Floor Using Reinforcement Learning, Kevin Parks May 2026

Discovering Strategic Behaviors In The Floor Using Reinforcement Learning, Kevin Parks

All Graduate Reports and Creative Projects, Fall 2023 to Present

This project investigates how a reinforcement learning (RL) agent can develop territorial strategies in a highly stochastic, grid-based approximation of the television game show The Floor. I design a custom Gymnasium-compatible environment that models the show’s core mechanics on a 10×10 board, including probabilistic duels governed by player skill, adjacency-constrained attacks, chain-attack rules, and a Randomizer mechanism for selecting new initiating players. A Maskable Proximal Policy Optimization (Maskable PPO) agent is trained under several reward configurations and evaluated against stochastic non learning opponents as well as random and “always pass” baselines.

Across experiments, the best-performing configuration achieves a win …


Financial Overconfidence, Borrowing, And Life-Cycle Outcomes, Jessica B. Parkinson May 2026

Financial Overconfidence, Borrowing, And Life-Cycle Outcomes, Jessica B. Parkinson

All Graduate Reports and Creative Projects, Fall 2023 to Present

This paper studies the effects of overconfidence in a lifetime consumption and savings model that allows for debt accumulation. Overconfidence, a well-documented behavioral bias, leads individuals to hold distorted perceptions of the different interest rates that they face on their savings and on their borrowings. While existing life-cycle models with overconfidence abstract from debt, I introduce a spread between the interest rates on savings and on borrowings, where the overconfident individual forms distorted perceptions of this spread. To model the actual and the perceived spreads, a continuously differentiable logistic function is utilized, and these spreads are incorporated into a standard …

All Graduate Reports and Creative Projects, Fall 2023 to Present

Graduation from high school is a critical milestone that leads to better job opportunities, higher education, and a lifetime of economic stability, which is why improving graduation rates is a critically important focus. However, many students who attend alternative schools face significant barriers to graduation, including inconsistent attendance, academic deficits, and personal challenges. The purpose of this creative project is to develop a self-determination intervention to support students when working on credit recovery. This creative project includes (1) a description of relevant research used to inform this project, (2) a description of the intervention and how it worked for students, …


Vernacular Religiosity: Liminality, Mentorship, And Communal Reciprocity In Women's Religious Communities, Megan J. Miller May 2026

Vernacular Religiosity: Liminality, Mentorship, And Communal Reciprocity In Women's Religious Communities, Megan J. Miller

All Graduate Reports and Creative Projects, Fall 2023 to Present

This thesis is a study on women’s religious communities, and the vernacularized traditions practiced by the women themselves from a folkloric perspective. Examining the creative and meaningful ways women find to interact with their faith on a daily basis, this thesis proposes a natural cycle of religious participation which allows the women to move between active and passive participation roles within their religious communities, and creates equitable spaces for women by relying on the communal reciprocity of the group.

By focusing on individual women and their experiences and belief practices as part of a larger community of religious practice, this …


Open Space Management Planning: A Framework And Case Study From Eagle Mountain City, Utah, Nathan K. Shumway May 2026

Open Space Management Planning: A Framework And Case Study From Eagle Mountain City, Utah, Nathan K. Shumway

All Graduate Reports and Creative Projects, Fall 2023 to Present

Open Space Management Plans (OSMPs) are increasingly used by municipalities to guide the long-term stewardship of natural lands; however, little formal guidance exists regarding how these plans are structured, developed, or organized in practice. While numerous OSMPs are publicly available, their compositional logic, procedural workflows, and thematic priorities remain largely undocumented within academic literature. This study addresses that gap through a qualitative document analysis of fifteen publicly accessible OSMPs from the western United States, published between 2015 and 2024.

Using manual matrix-based coding in Microsoft Excel, each plan was analyzed through three lenses: structural composition, procedural development, and thematic content. …


Patterns Of Acquisition For /ɹ/ Across Phonetic Contexts, Hailey Nielson May 2026

Patterns Of Acquisition For /ɹ/ Across Phonetic Contexts, Hailey Nielson

All Graduate Reports and Creative Projects, Fall 2023 to Present

Purpose: 

This study examined longitudinal changes in /ɹ/ production (i.e., the “r” sound) among 14 children aged five to seven at risk for persistent speech sound disorders (SSDs). Children at risk for SSDs show slower or atypical development of /ɹ/, yet little is known about which early patterns predict persistent difficulty, making it difficult for clinicians to prioritize caseloads and provide timely intervention. Using perceptual accuracy ratings across varied /ɹ/ contexts, we modeled growth in /ɹ/ accuracy across different word contexts and evaluated the extent to which early accuracy and changes in /ɹ/production predicted mastery at age seven.

Methods: 

Longitudinal …
