WRI is a state-managed program in Utah that implements cross-boundary habitat restoration projects. Local, state, and federal government agencies as well as non-profit organizations convene on five regional teams to design and evaluate projects. Project partners are engaged at a local level while most program administration occurs at the state level. A case study of WRI was conducted, making use of interviews with 33 participants, document review, and field observations. …

Cultural Adaptation Of A Single Session Acceptance And Commitment Therapy Guide For College Students In Uganda, Miriam Mukasa Kasozi

All Graduate Theses and Dissertations, Fall 2023 to Present

Mental health problems such as depression, anxiety, and stress are common among Ugandan university students and can make it difficult for them to succeed in school or maintain well-being. However, many students do not have access to professional mental health care. Digital self-help programs can make support more available, especially when they are designed to fit the local culture and context. This project examined how an online program called ACT Guide Lite, which teaches skills from Acceptance and Commitment Therapy (ACT), could be adapted for use with Ugandan college students. Students and other university community members first completed the program …

Characterizing Metabolic Flux Of Plant Secondary Metabolites From Diverse Animal-Source Foods To Humans, Muhammad Ahsin

All Graduate Theses and Dissertations, Fall 2023 to Present

There is a popular saying: “You are what you eat.” But does this also mean, “You are what your food eats”? This dissertation explores that question by examining how farming practices shape the nutritional quality of meat—and what, if anything, those differences mean for the people who consume it. While modern livestock production and nutrition research often emphasize protein and fat, this work tests the idea that animals function as biological mediators, linking soil and plant conditions to human diets through the chemical composition of meat and milk. To evaluate this hypothesis, we tracked health-relevant plant compounds— phytonutrients—across the soil–plant–animal–human …

Social And Institutional Factors Influencing Restoration Decisions In Sagebrush Plant Communities In The Great Basin, Carmen Calzado-Martínez

All Graduate Theses and Dissertations, Fall 2023 to Present

Sagebrush landscapes of the Great Basin in the western United States have changed dramatically over the past century. Invasive grasses, repeated wildfires, and past land-use practices have made it increasingly difficult for native plant communities to recover once they are damaged. Most restoration efforts occur after disturbances such as wildfire, when ecosystems may already be severely degraded. An alternative approach is proactive restoration, which aims to strengthen ecosystems before major damage occurs. 

This dissertation examines whether proactive restoration strategies could realistically be used in sagebrush rangelands and what factors influence their adoption. The research combines three complementary approaches. First, interviews …

The Dark Side Of Sport: Exploring Conceptualizations And Operationalizations Of Authority Figure-Athlete Abuse, Katherine Nicole Alexander

All Graduate Theses and Dissertations, Fall 2023 to Present

Although sport can be a fun and positive environment, it can also be a unique and common setting for athlete abuse. Coaches and other authority figures can serve in positive and negative caregiving roles, and many athletes report experiencing at least one form of abuse perpetrated by these important authorities during their sporting careers. We have less research on experiences of abuse in athletes from the United States. The current dissertation was designed to explore ways to more effectively and accurately define and measure athlete abuse perpetrated by authorities and coaches among adults in the United States. Given that there …

Forage Responses To Biological Inoculant And Seed Rates In The Intermountain West, Roy Reid

All Graduate Theses and Dissertations, Fall 2023 to Present

Improving the efficiency of fertilizer and seed use is increasingly important for forage producers in the Intermountain West, where alfalfa and silage corn form the foundation of dairy and livestock feed. This thesis evaluates two strategies designed to boost crop productivity: microbial fertilizer coatings and variable-rate seeding.

The first study examined whether Powercoat®, a fertilizer-applied microbial inoculant, could enhance yield, forage quality, or soil phosphorus availability in alfalfa grown on four commercial fields in northern Utah. Across all locations, fertilizer increased yield at only two sites, and Powercoat did not provide additional improvements in yield, forage quality, or soil nutrient …

Does Psychosocial Stress Moderate The Association Between Indicators Of Vascular Health And Cognitive Performance: An Examination In Native Hawaiian - Pacific Islander And Non-Nhpi Older Adults, Maddy Mills

All Graduate Theses and Dissertations, Fall 2023 to Present

Late-life cognitive decline and dementia that are unrelated to normal aging are a source of major global health concerns. Vascular risk factors, including high blood pressure, high cholesterol, and diabetes, along with psychosocial stress, are well-established risk factors for cognitive decline. However, no research has explored how these variables interact to influence cognitive performance in older adults. Native Hawaiian-Pacific Islanders (NHPI) face disproportionate rates of vascular risk factors linked to cognitive decline, yet this population has been historically underrepresented in health research. As a result, limited evidence exists regarding how these factors collectively impact cognitive performance in this population. This …

Post-Wildfire Erosion And Biogeochemistry: Integrating Aerial Imagery And Soil Testing To Assess Landscape Recovery, Justin A. Allred

All Graduate Theses and Dissertations, Fall 2023 to Present

After a wildfire, land managers are required to monitor large tracts of land with limited time and budgets. Traditionally, tracking landscape recovery is a time intensive process. This research explored the effectiveness of using drones (UAVs), strategic soil sampling, and computer modeling as additional tools for land managers in order to monitor the recovery more efficiently.

By using drones to collect aerial imagery and using machine learning, plant regrowth was monitored in back-to-back years. The machine learning model performed well at telling broad groups apart (trees vs grass) but it struggled to identify differences between plant species. Because many plants …

Probing The Roles Of Connexin 43 Hemichannels In A Mouse Model Of Alzheimer's Disease, Madison Treasure-Areno

All Graduate Theses and Dissertations, Fall 2023 to Present

Alzheimer’s disease is a progressive disorder involving neuronal death and cognitive decline, such as memory loss and changes in personality. One feature of the disease is buildup of abnormal protein called amyloid-beta in the brain. Amyloid-beta may activate support cells called astrocytes, triggering them to release large amounts of chemicals, possibly harming nearby cells. This study set out to examine the roles of the channels on astrocytes involved in releasing these chemicals, called connexin 43 hemichannels. Using a mouse model of Alzheimer’s disease, this study blocked the hemichannels using the drug Tonabersat, and measured spatial learning and memory in a …

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

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, …

Advancing Context-Aware Detection Of Socially Harmful Discourse Using Transformer-Based Models, Santosh Chapagain

All Graduate Theses and Dissertations, Fall 2023 to Present

Social media platforms are a central part of modern communication, shaping how people share ideas, build communities, and discuss social issues. While these spaces can support connection and self expression, they also enable the spread of harmful language such as hate speech. At the same time, social media is an important place where members of marginalized communities, including sexual and gender minorities, express stress, discrimination, and emotional challenges in ways that are often indirect and context dependent.

This research examines whether modern artificial intelligence systems can better identify harmful language and expressions of minority stress in online posts. The study …

All Graduate Theses and Dissertations, Fall 2023 to Present

Smoking tobacco is the leading avoidable cause of death and drives many health problems. Nicotine, the main chemical in tobacco products, keeps people using it. This study used the Rat Electronic Nicotine Delivery System (RENDS), an inexpensive and freely shared, to examine e-cigarette use in adolescent and adult female rats by exploring four phases of nicotine delivered and not delivered to understand use patterns among ages. Our study found that both adolescent and adult female rats chose to inhale nicotine when given the opportunity, showing drug-seeking behavior. Overall, nicotine use was similar between ages. These results could help inform therapies, …

Dyadic Agreement In And Task Correlates To A Measurement Of Conversational Success, Samantha Budge

All Graduate Theses and Dissertations, Fall 2023 to Present

Successful conversation matters for social connection, wellbeing, and quality of life, but people do not always agree on whether a conversation was successful, even when they participated in the same interaction. Conversation is also commonly measured through task success, even though it’s unclear how task success correlates to how successful a conversation feels. This study examined how conversational success is experienced by different conversation partners and whether feeling successful in a conversation is related to how well a task is completed.

Participants took part in a structured conversational task and then rated their own conversational experience using a self-report questionnaire …

All Graduate Theses and Dissertations, Fall 2023 to Present

Drawing on Bandura’s self-efficacy theory, this exploratory multi-case study examines how engagement in an engineering designed-based unit, specifically through an intervention focused on iterative improvements, influences middle school girls’ self-efficacy. This study was conducted in a suburban public middle school. It involved five female participants enrolled in a seventh-grade science classroom. Qualitative data were collected from pre- and post-interviews, self-reflection journals, observations and student artifacts. Multiple data sources were triangulated to ensure the credibility and depth of the findings. Qualitative data were analyzed using inductive and deductive coding to produce open codes, axial categories driven by Bandura’s four sources of …

Influence Of Predation Risk On Elk Feeding Behavior In A Multi-Predator Environment, Rosemarie C. Pugh

All Graduate Theses and Dissertations, Fall 2023 to Present

Sometimes predators don’t just affect prey by killing them, they can also change how prey behave. For example, animals may spend more time watching for danger and less time eating, which could affect their health and survival. In Yellowstone National Park, past research has suggested that elk may reduce feeding because they are trying to avoid predators like wolves and cougars. However, most previous studies have only looked at elk behavior during the daytime and have often looked at responses from single predators rather than multiple.

In this study, I used high-resolution tracking collars equipped with motion sensors to directly …

Development Of A Laboratory Apparatus For Evaluating Infiltration Performance Of Filter Strips In Utah, Pranish Dahal

All Graduate Theses and Dissertations, Fall 2023 to Present

Stormwater from Utah’s roadways often carries pollutants such as oil, metals, and sediments, especially during small storms when runoff is not diluted. Vegetated filter strips—areas of soil and vegetation placed alongside roads—are one of the most effective ways to capture and clean this runoff before it reaches rivers and lakes. However, choosing the right combination of topsoil and base soil for these filter strips is difficult, expensive, and traditionally requires multiple field visits.

This thesis introduces a laboratory device that allows engineers to test how different soil combinations absorb and filter water without having to go to the field each …

All Graduate Theses and Dissertations, Fall 2023 to Present

In this master’s thesis, I collected and analayzed data from 429 participants, 78 of whom reported having experience with parental infidelity, namely having at least one parent be sexually unfaithful to the other. The purpose of this study was to better understand the long-term impacts of experiencing parental infidelity during childhood. Participants with and without experience of parental infidelity were invited to complete an online questionnaire about potential experiences with parental infidelity, emotional well-being, attachment security in adult romantic relationships, couple satisfaction with current romantic partner, and attitudes (permissive versus accepting) towards potentially unfaithful behaviors of infidelity and pornography. I …

Out Of Sight, Out Of Mind? Psychological Distance And Public Perceptions Of The Great Salt Lake, Nathan Thompson

All Graduate Theses and Dissertations, Fall 2023 to Present

Over the past several years, Great Salt Lake has received a lot of media attention, both locally in Utah as well as nationally and even internationally. Within Utah, public perception surveys have indicated that concern about the lake varies depending on how low the lake levels are. This suggests that a concept called psychological distance might be influencing concern about the lake as well as support for strategies to help the lake. Psychological distance is the perceived distance a person has from an object, event, or person and is manifested in four ways: across physical distance (spatially), across time (temporal), …

Multiple factors of belonging are explored, including belonging in human relationships, belonging to oneself, and feeling a sense of belonging to a physical place. Each essay contains three cohesive narratives—called “strands”—which are woven together to form a single essay. These strands include the author’s personal experiences, site visits conducted by the author, and various research topics. The personal experiences explore the author’s relationship to belonging contextualized by his pure obsessive-compulsive disorder. The site visits recount the author’s experiences in natural and community-oriented places. The research …

Food-Form Delivery Of Spore-Forming Probiotics As An Alternative To Gavage In Animal Models, Aubreyona Faith Migliori Skalka

All Graduate Theses and Dissertations, Fall 2023 to Present

Western dietary patterns are characterized by nutrient-poor, calorie-rich diets and have been linked to poor health outcomes and gut inflammation phenotypes. Probiotics are often taken to support gut health, but many beneficial bacteria do not survive transport through the digestive system to produce any effect. Spore-forming bacteria, such as Bacillus coagulans, are more resilient due to their hardy outer coat which aids in survival through many obstacles encountered in the gastrointestinal tract, including acidic stomach conditions. In research studies, probiotics are usually given to mice through a procedure called oral gavage, where a tube is used to deliver the …

Production Of Hydrolyzed Lactose Syrup From The Acid Whey, Aubrey Jean Arbon

All Graduate Theses and Dissertations, Fall 2023 to Present

Acid whey has gained significant attention within the dairy industry due to its complex matrix and the processing challenges. This by-product contains lactose that can be isolated, hydrolyzed, and further processed to produce hydrolyzed syrup. To optimize lactose utilization, it is essential to fine-tune the kinetics of the β-galactosidase enzymes used for lactose hydrolysis. To analyze sugars in acid whey, and LC-MS-based chromatographic method was developed. Once the method was developed, the kinetics of β-galactosidase were optimized with respect to enzyme concentration, pH, and temperature. The goal was to achieve the highest possible lactose hydrolysis. The hydrolyzed acid whey was …

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 …

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. …

Which Energy Expenditure Equation Is Most Accurate In A Field-Based Setting?, Merrill C. Ward

All Graduate Reports and Creative Projects, Fall 2023 to Present

Several energy expenditure prediction equations for walking on varied terrain exist; however, these predictions are often theoretical and have not undergone rigorous field testing for accuracy. Field research on this topic is sparse. The aim of this study was to determine if any existing energy expenditure prediction equations are accurate in a field-based setting with load and gradient being taken into account (i.e., under conditions that are most applicable to day hiking). This was done by directly measuring relative VO₂ (ml/kg/min) of study participants and comparing these direct measurements to the values generated from the existing prediction equations. Fifteen …

I wrote a workbook for the individuals and one for the couple to work on together. Together, the workbooks will help couples improve communication and implement healthy communication behaviors regarding …

Check-In/Check-Out Implementation Across Grade Levels For Improving Unexcused Absences In A High School Setting, Otis C. Bitsuie

All Graduate Reports and Creative Projects, Fall 2023 to Present

Chronic absenteeism may contribute to declining graduation rates for many students with disabilities. Students with disabilities face challenges with academic and emotional behaviors. Chronic absenteeism causes students to fall behind with classroom materials, and they are unable to utilize instructional supports, emotional supports, or assistance with transitions. Students with disabilities who miss class often tend to drop out of school, which leads to difficulties with navigating post-high school life. Students who do not obtain a school diploma often experience high unemployment rates, homelessness, and incarceration. Students facing chronic absenteeism need interventions that will improve problem behaviors amongst students. I will …

Seasonal Body Composition And Neuromuscular Changes In High School Wrestlers: Medicine Balls For Fatigue Testing, Courtney Mccall Condie Carroll

All Graduate Reports and Creative Projects, Fall 2023 to Present

This study examines the effects a single wrestling season has on high school athletes’ body composition, muscle quality, membrane capacitance, and neuromuscular performance, and whether instrumented medicine balls are sensitive enough to serve as a field test for chronic fatigue. Twenty-five high school wrestlers (males=18, females=7) were recruited and assessed pre-season (Pre), mid-season (Mid), and end-of-season (Post). Outcome measures included body mass, fat-free mass, fat mass (via bioelectrical impedance spectroscopy), echo intensity (EI, via B-mode ultrasound) of the vastus lateralis (VL) and biceps brachii (BB), and countermovement rotational and backward-overhead throws with medicine balls instrumented with accelerometers.  Repeated measures ANOVA …

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 …
