Through this qualitative study, participant feedback, and analysis, this project examines how structured peer support can create meaningful change for this population. The following paper outlines the development of the group, the theoretical foundations that guided …

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 …

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 …

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 …

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. …

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) …

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) …

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 …

Decreasing Inappropriate Student Behavior Using Interdependent Group Contingency: Students With Intellectual Disabilities, Shelby Craig

All Graduate Theses and Dissertations, Fall 2023 to Present

Students with intellectual disabilities have the right to participate in the same educational activities as their peers while receiving appropriate supports. Many schools implement Positive Behavior Interventions and Supports (PBIS) to promote appropriate behavior through structured reinforcement systems, including group contingencies. This study examined the effectiveness of a group contingency intervention, the Caterpillar Game, in reducing inappropriate behaviors among six students with intellectual disabilities. Results indicated a consistent decrease in inappropriate behaviors following implementation of the intervention.

Student Programming Behavior With And Without Phone Notification Suppression, Gavin T. Eddington

All Graduate Theses and Dissertations, Fall 2023 to Present

Many students work on programming assignments while receiving notifications from their phones, such as text messages or social media alerts. These notifications can interrupt focus and make it harder to stay engaged with a task. This study examines whether silencing phone notifications helps students stay more focused while programming. 

We collected data from students in an introductory computer science course while they worked on programming assignments. Students completed some assignments with notifications silenced and others without. We measured their activity using software that records typing behavior and identifies when students take long pauses, which can indicate interruptions or loss of …

This research proposes a method that combines the flexibility of neural networks with the reliability of ensemble techniques, leading to more robust and accurate predictions across different types of datasets. …

Exploring The Correlation Between Malnutrition And Food And Nutrition Insecurity In Inflammatory Bowel Disease, Heather Burr

All Graduate Theses and Dissertations, Fall 2023 to Present

Inflammatory Bowel Disease (IBD) may increase the risk of malnutrition because of nausea, vomiting, diarrhea and restrictive eating. In addition, patients with IBD may experience food and nutrition insecurity. Therefore, we conducted an online survey to assess risk of malnutrition and food and nutrition insecurity among adult patients with IBD in outpatient and community settings. Patients were recruited between July and December 2025, aiming to reach adults in the Rocky Mountain Region diagnosed with IBD. Data collected included demographics, health-related factors, risk of nutrition insecurity, risk of food insecurity, and barriers and facilitators to dietary management of IBD.

Fifty-seven patients …

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

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.
