Addressing Substance Use Disorder In Rural Appalachia: Improving Access And Treatment Outcomes For Justice-Involved Individuals, Jessica Muldowney

Electronic Theses and Dissertations

Background: Opioid use disorder (OUD) represents a critical public health crisis disproportionately affecting justice-involved (JI) populations, with approximately 65% of incarcerated individuals having substance use disorders (James & Beatty, 2006). Rural Appalachian communities face compounded challenges due to limited healthcare access, provider shortages, and cultural stigma surrounding addiction treatment. Despite evidence demonstrating that medication-assisted treatment (MAT) reduces recidivism and overdose deaths, only 20% of correctional facilities offer these services (Klein & Seppala, 2019).

Objective: This mixed-methods study evaluated organizational readiness and infrastructure capacity for implementing evidence-based OUD interventions, specifically MAT programs across three rural counties in northwestern North Carolina.

Methods: …

Transformer Vulnerability To Geomagnetically Induced Currents Using Layered Soil Conductivity Models, Junior A. Sterling

Masters Theses

Geomagnetically induced currents (GICs) pose a significant threat to modern power transformers connected to long high-voltage transmission systems, particularly in regions with low subsurface electrical conductivity. During geomagnetic disturbances (GMDs), time-varying magnetic fields induce surface electric fields that drive quasi-DC currents through grounded transformer neutrals. These currents can bias transformer cores, leading to saturation, waveform distortion, and potential system instability. Despite extensive research, the role of regional Earth conductivity in shaping electric fields and transformer response remains an area requiring deeper investigation.

This study analyzes how contrasting Earth conductivity profiles influence GIC magnitude and transformer saturation risk using two representative …

Effects Of Tourist Feeding On The Gut Microbiome And Ecophysiology Of Endangered Northern Bahamian Rock Iguana (Cyclura Cychlura), Erin Lucy Lewis

All Graduate Theses and Dissertations, Fall 2023 to Present

The lifespan and reproduction of an animal depends on maintaining a healthy physiology. The proportion of individuals that survive to an age at which procreation can occur is important to long-term stability of populations and contributes to species survival. Health in an animal is measured in a variety of ways, including through monitoring of the body’s physiological systems, as well as its ability to respond to invading pathogens, and through the different types of bacteria present in the gut. Relationships among those different health metrics have been discovered in recent years and have been found to play important roles in …

Sequential Products Of Anaerobic Denitrification In Calcareous And Noncalcareous Soils By Use Of The Gas Chromatograph, Grant S. Cooper

All Graduate Theses and Dissertations, Fall 2023 to Present

The sequential products of anaerobic denitrification were determined on seven Western soils (four alkaline, two acid, and one neutral) by soil and gas analysis. The soils with 1% alfalfa and added KNO3 were incubated at moistures slightly greater than field capacity and with an atmosphere of He. The soils and gases were periodically analyzed and balance sheets prepared. The sequence of NO3-->NO2-->N2O-->N2 operated in all soils. The rates of nitrogen interchanges and maximal amounts of nitrate, N2O2 and N2 were determined. From this data it was postulated that the rate-limiting process for denitrification in acid soils is …

Using Picturebooks In Elementary School To Support Discussion, Connection, And Community Action, Polly Parkinson

All Graduate Theses and Dissertations, Fall 2023 to Present

Children are in school to acquire knowledge, so the books they read are a significant influence on how they see themselves and others. School curricula often lack diverse voices, which may limit students’ views of themselves and how they relate to their communities. The research objective of this study was to examine the potential for fostering empathy in students, to encourage societal benefits of positive community behaviors, deepen understanding of history, and future contributions to an engaged democratic society.

The problem identified was that although much research exists discussing children’s literature and empathy, little explores whether that empathy leads to …

Effects Of Training And Self-Monitoring On Paraeducators' Use Of Behavior Specific Praise, Camille J. Lopez

All Graduate Theses and Dissertations, Fall 2023 to Present

Paraeducators support students with disabilities in special education classrooms but often receive limited training in effective behavior support strategies. This study examined whether training combined with self-monitoring increased paraeducators’ use of positive, specific praise and reduced the use of reprimands during instruction. Paraeducators were trained to use and track their own praise while working with students. Results showed increased use of positive praise and decreased reprimands following the intervention. These findings suggest that brief, low-cost training and self-monitoring can improve paraeducator instructional practices and support positive classroom environments for students with disabilities.

The CaST has moderate item difficulty and high item discrimination, on average, with high reliability and no gender- or age-related item bias. In Chapter 3 (Paper 2), I identify seven item design features from the CaST assessment and examine their impact on item difficulty. All item design …

Freshwater Mussel Reintroduction And Recolonization Habitat Modeling Using Hydraulic, Sediment And Geomorphic Parameters, Megan Elizabeth Dinicola

All Graduate Theses and Dissertations, Fall 2023 to Present

Freshwater mussels are an important group of aquatic animals that live within the riverbed, but their populations have been drastically reduced by habitat alteration and other anthropogenic activities. In an effort to bolster populations, river managers and biologists are using mussel reintroductions as part of their restoration efforts but there are gaps in our understanding of where to reintroduce mussels within a river to see them create self-sustaining populations. This research helps shrink this gap by better understanding the physical habitat needs and population expansion potential of subadult freshwater mussels, or the size of mussel that hatcheries grow for reintroduction, …

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 …

Drought-Tolerant Plants Of Great Salt Lake: Determining Dormancy Break, Germination, And Seeding Timing Requirements To Improve Restoration Under Hydrologically Extreme Conditions, Montana Horchler

All Graduate Theses and Dissertations, Fall 2023 to Present

Wetlands are declining worldwide, and those in arid regions are especially vulnerable to climate change, drought, water diversions, and other human pressures. As a result, land managers increasingly rely on active revegetation to re-establish native plant communities and their associated ecosystem functions. Restoration that utilizes seeds as the propagule source is often the most cost-effective way to revegetate large areas, but in highly variable environments such as exist at Great Salt Lake, Utah, drought and flooding regularly limit plant establishment. Restoration practitioners require science-informed strategies to reach their goal of establishing diverse native plant communities with high native species cover. …

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 …

Analyzing The Influence Of Stem Project-Based Learning On Students' Perceptions And Career Interest In Stem, Melissa S. Barker

All Graduate Theses and Dissertations, Fall 2023 to Present

Although science, technology, engineering, and mathematics (STEM) enrichment programs aim to increase participation in STEM, the design features that meaningfully influence adolescents’ task values and career-related beliefs remain insufficiently specified. The purpose of this study was to investigate whether STEM PBL activities designed with an interest-focused theoretical lens of Subjective Task Value (STV) and Social Cognitive Career Theory (SCCT) influence students’ perceptions of STEM courses, majors, and careers. Additionally, I sought to understand what elements of the STEM PBL experience were most impactful. I designed and taught STEM PBL activities for students from the Native American lands in southeastern Utah …

Comparing Strategies For Wetland Revegetation In An Uncertain Water Future, Hailey M. Machnikowski

All Graduate Theses and Dissertations, Fall 2023 to Present

Wetlands worldwide are expected to experience more frequent and intense droughts and floods due to climate change. These shifting water conditions introduce challenges to restoring wetland plants, especially using direct seeding. Seeding is cost and labor-efficient compared to planting, but seeds and seedlings are highly vulnerable to water stress, so restoration efforts often fail when conditions are too wet or dry. Understanding how to improve seed-based revegetation under these conditions is increasingly important. Therefore, we sought to understand the response, measured by percent canopy cover or dry biomass weights, of native plants to different durations of drought in greenhouse experiments, …

Mapping Spatial Variability For Precision Management In Utah’S Tart Cherry Orchards, Kurt T. Wedegaertner

All Graduate Theses and Dissertations, Fall 2023 to Present

Tart cherry orchards are a major part of the agricultural landscape in Utah, but producing cherries is becoming increasingly difficult and expensive. Orchard land is not uniform. Some parts of a field grow strong, healthy trees, while other parts struggle because of differences in soil, water, and landscape. Even though these differences exist, orchards are usually managed the same way everywhere. Over many years, this causes some trees to become much larger than others, making orchards harder to manage, less efficient to harvest and prune, and more costly to maintain.

This research focused on finding practical ways to measure these …

Developing And Improving Digital Image Correlation (Dic) Techniques For Challenging Environments, Prasenjit Dewanjee

All Graduate Theses and Dissertations, Fall 2023 to Present

Understanding how materials and parts deform during testing is crucial for creating safer and more reliable engineering systems. Engineers need to measure not only how much a part deforms, but also where deformation concentrates before any damage or failure happens. Digital image correlation (DIC) is a camera-based, non-contact measurement method that tracks surface motion and deformation across a whole area. It is particularly useful when traditional contact-based measurement techniques cannot withstand harsh conditions or capture enough detail. This dissertation develops optical methods to improve DIC in three challenging measurement situations. First, a shortwave ultraviolet lighting technique is developed to reduce …

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), …

The State of Utah funded agricultural water optimization studies to determine how agricultural water depletion can be decreased while maintaining or improving yields. Conversion from surface irrigation to drip irrigation is investigated as a method to decrease consumptive use.

Some Utah onion producers are converting from furrow irrigation to drip irrigation to decrease water and fertilizer use and improve profits. This study compares the consumptive use and yield of three drip irrigated onion fields against the consumptive use and yield of three furrow irrigated onion fields.

Arrays of soil moisture sensors at various depths were placed in drip and furrow …

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 …

Effect Of Agroecological Feeding Systems Of Dairy Cattle On The Nutritional Composition Of Milk, Sree Bhavya Immadi

All Graduate Theses and Dissertations, Fall 2023 to Present

How food is produced can influence both its nutritional quality and its impact on the environment. In recent years, regenerative (agroecological) farming practices have gained attention for their potential to improve soil health, biodiversity, and the nutritional value of foods. In dairy production, these practices often involve growing more diverse forage crops, reducing soil disturbance, and relying less on monoculture-grown feed rations. However, there is still limited real-world evidence showing how these practices affect the nutritional composition of milk produced on commercial dairy farms.

This dissertation explores how regenerative feeding and feed production practices influence the nutritional quality of milk, …

A Survey On Digital Reading Materials And Personal Study Of Christian Religious Texts, Teancum Price

All Graduate Theses and Dissertations, Fall 2023 to Present

Religion, including reading from religious texts such as scriptures, are a part of the daily lives of many people. Modern technology has influenced the way that this religious reading takes place, but its effects have not yet been studied. Existing research of the effects of technology on reading focus on topics such as reading comprehension, but the study of religious texts is often focused on achieving a religious experience, so the existing research does not capture the whole scope of these changes. In our study, we surveyed two universities (Utah State University and Abilene Christian University) to ask individuals how …

Examination Of The Association Among Family Communication Patterns, Attitudes Toward Sex, And Sexual Communication Self-Efficacy, Brooklynn Edelmayer

All Graduate Theses and Dissertations, Fall 2023 to Present

The purpose of this study was to gain a better understanding of the role that family communication plays in the development of sexual attitudes and sexual communication self-efficacy. Essentially, each family has a unique communication environment, which consists of how open communication is, the variety of topics a family might discuss, and expectations of conformity that parents have for their children. Attitudes toward sex can be conservative–reflecting traditional views toward sex–or progressive–reflecting tolerance and flexibility toward various sexual lifestyles. Sexual communication self-efficacy is the degree to which an individual feels comfortable communicating about sex with a sexual partner. Participants in …

Cannabis: A Model Plant To Study Light-Mediated Reproductive Development, Madigan J.H. Eckels

All Graduate Theses and Dissertations, Fall 2023 to Present

Cannabis (Cannabis sativa) is a plant of increasing importance for research, medical, recreational, industrial, and agricultural purposes, but a strict legal landscape means that it was chronically understudied. Now that research institutions can utilize this plant for study, we require updated terminology to describe various cannabis flowering types that occur under ideal and non-ideal growing conditions. We introduce new flowering terminology and describe them in text and with photographs.

Plants use light as a resource to power photosynthesis, and a greater total sum of photons generally increases yield. In controlled environment agriculture where growers utilize light fixtures instead …

Designing A Uae-Centric Integrated Mobility System: Linking Transport,Traffic, And Urban Data For Smarter Travel, Alreem Jabir Alshamsi

Theses

Urban mobility systems are central to smart city performance; however, in many rapidly developing cities, mobility services remain fragmented across agencies, platforms, and datasets. In the United Arab Emirates (UAE), cities such as Dubai and Abu Dhabi have made significant investments in digital infrastructure and intelligent transport solutions. Despite this progress, existing mobility applications continue to operate in functional silos, limiting real-time adaptability and cross-domain integration. Current platforms primarily focus on transport coordination and congestion avoidance, with limited integration of broader urban datasets such as building access schedules, environmental conditions, and localized service availability. This research addresses the absence of …

Subject. Object. Thing., Cristin Hand

Theses

Subject. Object. Thing. is part of an accumulating record of self-construction and self-reflection. The work considers the complications of visibility through self-portraiture, how the desire to be seen exists alongside the impulse to withhold, obscure, and substitute. Working across photography, performance, collage, and sculptural constructions made for the camera, I fragment, disassemble, and reconfigure my body as photographic subject and material. This exploration is structured around a series of oppositions; concealment/exposure, anonymity/specificity, subject/object, naked/nude, and destruction/reconstruction. I do not attempt to resolve these oppositions. Instead, I consider where these categories blur, contradict themselves, and become unstable. Central to this inquiry …
