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), …

A Mixed Methods Analysis On The Effect Of Active Learning On Extraneous Cognitive Load Within Undergraduate Statistics Courses, Michelle Brady Rich

All Graduate Theses and Dissertations, Fall 2023 to Present

Students enrolled in college-level statistics courses often lack the foundational skills of statistical concepts which can potentially lead to increased mental load. Additionally, the curricula within undergraduate classes often focus on traditional theory with little student exploration or participation. This combination of increased mental load and passive lectures can be explored through the Cognitive Load Theory (CLT). CLT examines how new information enters the limited capacity of an individual’s working memory and how exceeding this capacity affects the ability to transfer the information to long-term memory. This research focused on the extraneous cognitive load, or the load imposed by the …

Great Power Competition In Africa: U.S. Aid Responses To Chinese Aid And Investment, Ebenezer Nana Botsio

All Graduate Theses and Dissertations, Fall 2023 to Present

Over the past two decades, China’s rapid expansion of aid and investment throughout sub-Saharan Africa has raised questions about how the United States responds to growing competition in the region. While the impact of China’s aid has been the subject of considerable study, far less attention has been given to how other donors shift their strategies to adjust. This thesis asks a simple but rather consequential question: does the US change how it gives aid in Africa in response to China’s ever-growing footprint? 

With data from 54 African countries, I find that the United States does not attempt to directly …

Examining Motivations And Perceptions In Secondary Technology And Engineering Education: A Gendered Analysis Using The Fit-Choice Scale, Abigail Villanueva

All Graduate Theses and Dissertations, Fall 2023 to Present

This study examined why individuals choose to become secondary technology and engineering education (TEE) teachers and whether motivations differ between men and women. TEE programs help prepare students for careers in science, technology, engineering, and math (STEM), yet schools face teacher shortages and low female representation in the field. Understanding what draws people to this profession can support better recruitment and retention efforts. Sixty-six current TEE teachers completed a survey about the factors that influenced their decision to teach. Overall, the strongest motivations were a personal interest in teaching, enjoyment of working with young people, and the desire to make …

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 …

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 …

Longing For Home, Ryker Eggenberger

All Graduate Theses and Dissertations, Fall 2023 to Present

This thesis is a collection of creative nonfiction essays examining what it means to belong. 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 …

Rainbow Dominating Sets Of Graphs, Samuel L. Powell

All Graduate Theses and Dissertations, Fall 2023 to Present

The content of this thesis may be compared to a stack of plates with a common design that are broken, one at a time. If the plates are broken into large enough pieces you would be able to choose one fragment from each broken plate to discover the entire design that the plates share. For example, if you were still missing the center of the design after taking a piece from some plates, you could look for the piece of the next broken plate with the region in question.

We study the question of how many broken plates might guarantee …

Understanding Impact Of Redox Potential On Microbial Community Of Cheddar Cheese During Aging, Abrianna Y. Paez

All Graduate Theses and Dissertations, Fall 2023 to Present

Cheese ripening is a complex process that shapes the flavor, texture, and overall quality of cheese, yet many of the factors that control how these changes occur are still not fully understood. One factor that may play an important role is redox potential, which describes the balance between oxidation and reduction reactions happening inside the cheese. These reactions can influence both the activity of bacteria and the chemical processes that create flavor. Past efforts to control redox using chemical additives often harmed beneficial bacteria, limiting their usefulness.

In this study, we tested the use of mechanical disruption and gas exposure …

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 …

All Graduate Theses and Dissertations, Fall 2023 to Present

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 …

Honorata Memoria Prosequar: The Lives Of Republican And Augustan Women As Antecedents For Later Deifications, Megan Fairbanks

All Graduate Theses and Dissertations, Fall 2023 to Present

Emperors and some notable societal figures in the early Roman Empire are known to have practiced apotheosis, a state-sponsored process which confirmed that deceased men, women, and sometimes children had achieved the status of godhood. This process became official during the lifetime of Rome’s first emperor, Augustus, who deified Julius Caesar. As the process developed, it came to involve several formalized elements, including senatorial voting, a public ceremony (consecratio), and the production of commemorative images published through various media such as coins, paintings, and honorific statues. The purpose of this thesis is to determine the possibility of existing precursors for …

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

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 …

Domestic Cow Of Plenty: Gender And Womanhood In The Bhāgavata Purāṇa, Harshika Ajay Gupta

All Graduate Theses and Dissertations, Fall 2023 to Present

This thesis examines gender and womanhood in the Bhāgavata Purāṇa (Bhāgavata), a Sanskrit text from the 10th century CE that holds an important theological and cultural position in contemporary Hindu traditions. It decodes the Bhāgavata’s unique perspectives on the following: (1) gender, sex, sexuality, and reproduction, (2) women’s social normativity, and (3) women’s personhood and agency. This thesis argues that the Bhāgavata contains a unique theorization of gender and sex as well as a positive valuation of femininity, and that it imbues its narratives with practical resources and actions to recognize and expand the agentive capacity of women.

For scholars …

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.

How Novices Write Code: Discovering Best Practices, Matt Rau

All Graduate Theses and Dissertations, Fall 2023 to Present

Learning to program is a difficult endeavor, leading to chronically high failure rates in introductory programming courses. One thing that makes teaching programming difficult is that we don’t fully understand what problem solving habits and writing strategies separate successful programmers from struggling ones. Knowing how to teach these habits to a new programmer is an equally difficult challenge,

Studying the way people write code has proved difficult. Until recently, there was very little relevant publicly available data, and no good ways to analyze student programming behavior at a large scale. In this thesis, I address both issues. I publish a …

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 …

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 …

Numerical Investigation On Lightning Survivability And Residual Strength Of Scarf-Patched And Z-Pinned Cfrp Composites, Logan Hales

All Graduate Theses and Dissertations, Fall 2023 to Present

Carbon fiber reinforced polymer (CFRP) composites are critical in aerospace applications yet remain vulnerable to lightning strikes due to orthotropic electrical conductivity and poor thermal resistance. Over the past decades, lightning-strike damage in pristine CFRP has been extensively investigated. However, the response of damaged and subsequently repaired laminates remains poorly understood, raising concerns about the structural integrity of repaired aircraft. This study aims to develop a sequentially coupled thermo-structural modeling framework to quantify how two common composite repair strategies (scarf patching and z-pinning), along with patch size, pin material, and configuration, influence lightning-induced damage and the residual flexural strength of …

Specimen, Basil Payne

All Graduate Theses and Dissertations, Fall 2023 to Present

“Specimen” is a collection of my original poetry drawn from my thesis that explores identity and experience through the lens of nature. Specimens are dead, preserved individuals of nature who are used for scientific study. They help us humans understand the world better, help us make scientific advancements, but can they do more than that? In my poetry, I see myself and all the other individuals as specimens, singularities with lessons to teach and things to learn. Listening to the more-than-human world, acknowledging their differences can help us understand the aspects of ourselves that feel out of place, be those …

Assessing Geomorphic Change From Large Wood Additions In An Intensively Monitored Watershed, Alexander Walt

All Graduate Theses and Dissertations, Fall 2023 to Present

Rivers across the American West are under stress. Over time, human activities have decreased riparian vegetation and removed naturally occurring large wood from fallen trees and beaver dams. Overgrazing, wetland drainage, and artificial barriers like levees and berms have further changed these ecosystems, leaving behind simple channels that lack varied habitat for aquatic species.

Efforts to restore rivers have made some progress, but many projects are small in scale and focus more on reshaping the river rather than restoring the natural processes that keep it healthy. This study evaluates a different approach—Low-Tech Process-Based Restoration (LTPBR)—which works with nature to rebuild …

St-Fmformer: An Autoregressive Generation Framework For Scientific Ensemble Data Predictions, Md Robiul Islam

All Graduate Theses and Dissertations, Fall 2023 to Present

Understanding how physical systems change over time is important in areas such as weather prediction, fluid dynamics, and environmental science. However, accurately predicting future behavior is difficult because these systems are complex and constantly evolving. 

This research develops a deep learning approach to predict how such systems evolve over time. The model learns patterns from past observations and uses them to generate future states step by step. This provides a faster alternative to traditional simulation methods while maintaining strong predictive performance. 

The proposed method focuses on improving the consistency of predictions over time and is designed to work across different …

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 …

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 …

It's Okay, I'M Fine: A Communication Approach To Masculinity, Vulnerability, And Emotional Intimacy In Male Friendships, Nathan M. Spencer

All Graduate Theses and Dissertations, Fall 2023 to Present

Vulnerability is a key part of any relationship, as it allows people to feel more connected and closer to one another. However, toxic masculine norms are inhibiting men from being vulnerable in their relationships, especially in their friendships with other men. This study seeks to explore how vulnerable communication can lead to increased feelings of emotional intimacy and partner responsiveness within male friendships, even when it goes against the person’s expectations. Findings suggest that when a man is exposed to a vulnerable message, he will perceive an increase in both emotional intimacy and partner responsiveness. Another factor was that when …

From Stuckness To Sustainability: Tailoring A Conflict Management Framework To Support Emotional Processing In English Teaching, Isabelle Scott

All Graduate Theses and Dissertations, Fall 2023 to Present

Nationally, teachers are struggling to simply stay in the career, let alone thrive in it, and many education researchers are recognizing that teaching has become a largely unsustainable career for an increasing number of educators. There are many complex challenges that English Language Arts (ELA) teachers face that contribute to this dissatisfaction and the unsustainability of the career, including the demanding human and relationship-focus of the work, the emotional intensity in this type of caring, intense debates and controversies occurring in national politics that then play into the classroom, and an overarching disillusionment with teaching. This thesis explores such problems …

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 …

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, …
