Behind The Smile: A Qualitative Study On Dentist Burnout And Workplace Satisfaction In Cache Valley, Luke Thomas Hatch

Undergraduate Honors Capstone Projects

This qualitative research study examined satisfaction, stressors, and burnout among dental professionals in Cache Valley, Utah. Eight practitioners at various points in their careers were interviewed with a range of specialties including general dentistry (n = 3), pedodontics (n = 3), oral and facial surgery (n = 1), and orthodontics (n = 1). Analysis of the interviews showed that level of clinical autonomy was a primary factor influencing burnout levels. Stress levels in more experienced practitioners and owners tended to be lower than those who worked in multiple practices (multi-doctor) or with corporations. Individuals in these environments reported higher levels …

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.

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 …

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 …

Extracting Wildfire Influence From Natural Streamflow Variability To Inform Post-Fire Peak Flow Predictions, Haley Anne Canham

All Graduate Theses and Dissertations, Fall 2023 to Present

Wildfire is a natural process, however, wildfire occurrence, severity, and size is increasing globally along with large storms. Despite the expectation that floods will be larger after wildfire, a large range in post-fire flood size has been observed. This creates challenges for emergency managers to prepare for flooding in areas where wildfire might occur. Aside from wildfire, many other factors influence the size of floods, making it difficult to isolate the influence of wildfire. This work finds that factors including wetter versus drier years and seasons can alter the size of a flood, effectively hiding the influence of wildfire. Additionally, …

Mechanisms Of Life History Trade-Offs In The Evolution Of Eusociality, Frances Katherine Hunter

All Graduate Theses and Dissertations, Fall 2023 to Present

When faced with stressors such as pathogen infection, organisms must invest energy in defense or risk death. Because resources are limited, mounting an immune response often comes at the expense of other costly activities such as reproduction. The costs of immunity are shaped by factors including behavior, nutrition, age, and evolutionary history.

Social insects (e.g., ants, bees, and wasps) offer a powerful system for studying these trade-offs because queens in these colonies appear to escape them—living long lives while reproducing prolifically. Bees, which include species that range from those which nest solitarily to those with complex social systems and many …

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, …

Examining Middle School Girls' Self-Efficacy Changes During A Design-Based Engineering Unit, Emily Lehnardt

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 …

The Fourth Skill Revisited: A New-Ish Approach To Latin Pedagogy, Tyler Perry

All Graduate Theses and Dissertations, Fall 2023 to Present

This thesis examines a new way of teaching Latin that combines Gareth Morgan’s The Fourth Skill method with the traditional grammar-translation approach. Latin teaching has often moved between two extremes. Grammar-translation focuses heavily on analyzing grammar, while modern immersion-style approaches focus more on understanding the language through exposure. Each method has strengths but also clear limitations. Morgan’s The Fourth Skill (1968) tried to balance these approaches by focusing on reading real Latin texts, but it relied heavily on Morgan’s personal teaching and included little direct grammar instruction.

To address these problems, this study tested a revised version of the method …

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 …

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. …

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 …

Housing Markets In The American West: A Dynamic Time Warping Analysis Of Inter-City Relationships, Daniel Johnson

All Graduate Theses and Dissertations, Fall 2023 to Present

Housing markets revolve around perhaps the most consequential good to the average person, yet the relationships between local housing markets remain understudied. While major American cities appear to follow similar patterns, the nature of these connections is not fully understood. This project looks at housing markets across the western United States, using Dynamic Time Warping (DTW) to identify which cities tend to lead or lag others in price movements, and look at the overall similarity of their market movements. We also explore whether geographic distance, population growth, and income growth help explain why some markets are more similar than others. …

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 …

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 …

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 …

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, …

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 Rodent Electronic Nicotine Delivery System (Rends): Effects Of Age On Self-Administration Of Inhaled Nicotine In Female Rats, Daniel Santos Da Silva

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, …

Enhancing Evidence-Based Practice Decision-Making Among Practitioners In Adult Disability Service Settings, Aubrey Vance

All Graduate Theses and Dissertations, Fall 2023 to Present

Board Certified Behavior Analysts (BCBA®s) working in adult disability services often face challenges such as high caseloads, limited oversight, and restricted resources, which can make it difficult to use individualized, research-supported interventions. Although evidence-based practice (EBP) is central to applied behavior analysis, many practitioners receive little training on how to integrate research evidence, client values, and clinical judgment into their decision-making. This study examined whether BCBAs could be effectively trained to use a structured decision-making framework based on the EBP model by Slocum et al. (2014). Using a multiple baseline design, we evaluated the effects of Behavioral Skills Training (BST) …

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), …

Visualizing Probabilistic Model Checking: An Interactive Framework For Exploring Ctmc Models, Ishara Mawelle Kankanamge

All Graduate Theses and Dissertations, Fall 2023 to Present

Probabilistic model checking is a critical method for analyzing systems characterized by uncertainty, such as communication protocols, randomized algorithms, and biochemical networks. While formal verification tools provide precise numerical data about these systems, interpreting these results is often limited by large state space, high-dimensional state space and time dependent evolution. Current tools typically output raw numerical data, offering limited support for intuitively understanding the time-dependent behavior of a model. This research presents an interactive visualization framework designed to bridge the gap between complex numerical analysis and human intuition. The framework integrates coordinated visual interfaces, including lower-dimensional state-space projections and synchronized …

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 …

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) …

Assessing Young Children's Computational Thinking: Validation Of Items And Item Design Features, And Diagnostic Approaches, Chungsoo Na

All Graduate Theses and Dissertations, Fall 2023 to Present

The goals of this multiple-paper dissertation are to evaluate the psychometric evidence of the Computational and Spatial Thinking Assessment (CaST), designed and developed by the Coding in Kindergarten (CiK) research team (supported by NSF #1842116). In Chapter 2 (Paper 1), I evaluate the psychometric quality of the CaST assessment at the item level. 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 …

All Graduate Theses and Dissertations, Fall 2023 to Present

Collaboration is necessary to address complex, cross-jurisdictional natural resource problems. To better understand the benefits and drawbacks of innovative collaborative structures, this research examined the Utah Watershed Restoration Initiative (WRI). 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. …

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 …
