Validation Of Head Above And Head Submerged Hydrostatic Weighing Equations And Air Displacement Plethysmography, Axel M. Miller

All Graduate Reports and Creative Projects, Fall 2023 to Present

Traditional hydrostatic weighing (HW) involves full body submersion at residual volume (RV), which may be uncomfortable. Thus, the purpose of this study was to investigate a more comfortable way to perform this method. HW with the head above water (HW_HAW) was compared to the traditional method of HW with head below water (HW_HBW) and to another method that also measures density by displacement, air displacement plethysmography (ADP). Equivalence was tested by comparing the body fat percentage (BF%), body volume (Vb), and body density (Db) of 27 subjects (15 M, 12 F) between the three methods. Results …

The Effects Of Temperature And Cardiotonic Steroids On Cardiac Function And Metabolism In Snakes, Hannah Wilson

All Graduate Theses and Dissertations, Fall 2023 to Present

The function of the heart provides a window into the physiology of vertebrates and a means of evaluating their response to the stresses imposed by diverse activities. I developed a miniaturized instrument to record electrocardiograms (ECGs), using open-source Arduino technology, that a snake can wear as a backpack. The backpack can also be used when the snake is in a metabolic chamber, to record the metabolic rate and ECG simultaneously. I first used the ECG backpack to record the physiology of snakes under different temperature conditions, to verify that the system worked as expected. the backpack was then used on …

Investigating Temporally Dynamic Models Of Choice In Rats And Bumblebees, Jack Van Allsburg

All Graduate Theses and Dissertations, Fall 2023 to Present

Temporally dynamic models of choice simulate how animals use past experience to make optimal decisions in variable environments. Chapter 1 briefly reviews a series of such modeling approaches and their mathematical properties. Extension of these models to longer experiments (more than 48 hours) designed to produce spontaneous recovery of choice (a behavioral phenomenon implicated in relapse) previously led to results not described well by current models. Chapter 2 comprises an empirical investigation of different explanations for these inconsistent results using rats, evaluating the effect of different test delays on preference following varied reward conditions. The results of the first two …

Examining The Development Of Collective Classroom Efficacy At The Secondary Level, Bradley K. Dutson

All Graduate Theses and Dissertations, Fall 2023 to Present

How can educators develop cohesive and productive learning communities at the secondary level? Prior research has investigated how classrooms develop collective classroom efficacy (CCE) or the shared belief that, as a classroom, they can achieve their learning goals together as a community. Previous studies suggest that CCE at the elementary level is developed with a teacher acting in the role of a community organizer. The teacher employs social and academic practices which incorporate the use of relevance, relationship, and responsibility. These help to establish four key elements of developing CCE which include: 1) a positive classroom environment, (2) persistence and …

Exploring Methods For Quantifying Uncertainty In Neural Network-Based Turbulence Closures, Cody Grogan

All Graduate Theses and Dissertations, Fall 2023 to Present

Machine Learning (ML) is a very promising field for data-driven modeling of different phenomena. In the field of Computational Fluid Dynamics (CFD), ML is an enticing alternative to traditional methods to improve the accuracy and computational efficiency of simulations. However, many ML models, like Neural Networks, don’t quantify their uncertainty or indicate their confidence in a prediction to those who wish to use them. This is especially important because the use of inaccurate ML predictions in a CFD simulation can greatly impact the validity of a simulation. However, with uncertainty quantification, an ML model can indicate to a modeler the …

An Embodied Social Demography For Trans And Nonbinary Workers, Jesse Ezra Shircliff

All Graduate Theses and Dissertations, Fall 2023 to Present

Recently, the separation of “sex” and “gender” has seen intense debate in public discourse, stemming from skepticism about the social sciences and the measurement and study of gender specifically. Meanwhile, the United States population is becoming more gender diverse, with roughly 1 in 200 people now identifying as trans gender or gender nonbinary (that is, as a gender that is different from that person’s sex assigned-at-birth or outside of the sex-gender binary). This growing population experiences numerous disadvantages across social life, including obstacles in one particularly important aspect of the American Dream: the right to have and hold a job. …

Adapting To Change In Amenity-Oriented Communities: Innovative Strategies For Shifting Social And Environmental Needs, Emma L. R. Epperson

All Graduate Theses and Dissertations, Fall 2023 to Present

Amenity-oriented communities are places with significant and desirable natural amenities that are highly visited and plentiful within the Intermountain West. These high rates of visitation create complex challenges such as congestion in recreation spaces and in towns and increase costs of living. These communities are typically rural and often do not have the resources, funding, or infrastructure to combat these challenges. Although tourists provide financial stability and other amenities to these towns, local wellbeing is highly impacted. Outdoor recreation and the nature connections derived from outdoor experiences are major contributors to wellbeing in amenity communities. This research investigates the changes …

Optimal Distributed Energy Resource Control And Scheduling In A Microgrid Framework, Timothy M. Dodge

All Graduate Theses and Dissertations, Fall 2023 to Present

As we use more renewable energy, such as solar power, and add new devices, such as electric vehicle chargers and battery storage, to our buildings, the management of electricity becomes more complex. These local energy sources and devices can form small "microgrids" that need careful coordination to work efficiently with the main power grid. The system figures out the best times to use, store or charge different devices (such as batteries and EVs) to avoid costly, high electricity demand spikes and help stabilize the main power grid, especially when asked by the utility company. A major part of this work …

Examining The Predictive Validity Of Adolescent Complete Mental Health On High School Academic Performance, Nai-Jiin Yang

All Graduate Theses and Dissertations, Fall 2023 to Present

This multiple-paper dissertation examines how adolescent complete mental health, based on the Dual-Factor Model, predicts high school academic performance. The Dual-Factor Model considers both psychological distress (such as internalizing and externalizing symptoms) and subjective wellbeing (such as life satisfaction and positive affect). The main research objective is to determine whether this comprehensive framework offers stronger predictive power for academic success than symptom-based approaches alone.

Two studies were conducted using self-report mental health data collected at three time points during an academic year. These data were analyzed alongside end-of-quarter grade point averages in English Language Arts, math, and overall GPA using …

All Graduate Theses and Dissertations, Fall 2023 to Present

In Kyrgyzstan, a country shaped by deep-rooted traditions and high rates of migration, women's lives are often influenced by powerful cultural expectations, economic pressures, and limited choices. My research explores how these forces intersect—particularly through the lens of bride kidnapping, migration, and how families use money and resources. Together, these issues reveal how gender inequality operates in everyday life, and how women navigate both constraint and resilience.

This dissertation includes three connected studies. The first examines how the COVID-19 pandemic disrupted international labor migration, especially for Kyrgyz migrants working in Russia. Many returnees lost their jobs and faced hostility or …

Evaluating Maternal Polar Bear Denning Habitat Along The Arctic Coastal Plain And Assessing The Potential For Noise Disturbance In Polar Bear Dens, Ethan Ducharme

All Graduate Theses and Dissertations, Fall 2023 to Present

Polar bears (Ursus Maritimus) in northern Alaska are increasingly choosing land instead of sea ice to build their maternity dens. As sea ice continues to decline due to climate change, this shift makes it more important than ever to identify and protect the areas where polar bears dig dens to give birth and raise their cubs. In the first part of my research, I used new satellite-based elevation data to map potential polar bear denning habitat across a large section of Alaska’s Arctic Coastal Plain. This technology allowed me to identify the types of sloped terrain where drifting …

Distal Impact Of Learning Trajectories On Motivational Factors In Second Language Acquisition Of Adult English Learners, Feng Zhang

All Graduate Theses and Dissertations, Fall 2023 to Present

Learning a foreign language is a long-term process sustained by learners’ motivation, self-efficacy, and self-regulation. While prior research has established that past performance influences these motivational factors, overlooking the impact of past performance on current motivational constructs. This dissertation explores how past learning performance impact current motivational factors. Using a person-centered approach, three subgroups were identified as latent learning profiles within the sample population based on their performance features: the high-performing early peak profile, the stable profile, and the rising profile. Regression models were conducted to evaluate the extent to which latent learning profiles predicted motivational variables. The results showed …

Understanding Power Dynamics Of Latter-Day Saint Marriages In The United States Of America, Bonnie Young

All Graduate Theses and Dissertations, Fall 2023 to Present

Power sharing is a key feature of romantic relationships. It is important to understand how various groups navigate power sharing within their relationships. Thirty-one participants who belong to the Church of Jesus Christ of Latter-day Saints (16 women and 15 men) reported on their experience of power-sharing in marriage. In-depth individual and couple interviews revealed that couples engage in four individual and relational processes that impact and promote equality in marriage: systemic influences, self-in-relationship processes, relationship processes, and identity outcomes. These processes have important implications for future research and therapeutic practice with Latter-day Saint, religious, and secular couples.

Living Pantry: Affordable Housing And Traditional Agriculture, Alanna S. Nafziger

All Graduate Reports and Creative Projects, Fall 2023 to Present

Utah is a beautiful and unique landscape with a vibrant food history that is, as I write this in 2025, undergoing some dramatic changes in both climate and population.

The population is projected to almost double by 2065, increasing by 2.8 million people over a 50-year period. Cache Valley, in the Northern part of the state, is projected to increase its population by 93% in that same time frame (Perlich et. al., 2017).

This population growth represents a huge increase in demand for housing, but while demand grows, the market becomes less affordable, with the median home price 6.26 times …

Alevi-Bektashi Ballads: Malady, Melody And Remedy, Mustafa Cingoz

All Graduate Theses and Dissertations, Fall 2023 to Present

This research focuses on how ballads play a central role in the cultural and spiritual life of the Alevi-Bektashi community in Türkiye. These ballads, performed by folk poets known as aşık (minstrel) with the stringed instrument bağlama are the inseparable elements of their daily life and sacred rituals. As rooted in the path of Ali, the fourth Caliph of Islam, and the teachings of 13th-century Sufi saint Haji Bektash Veli, Alevi-Bektashi ballads express shared emotions, struggles, and hopes. Therefore, my point of view argues that these ballads do more than preserve the Anatolian ballad tradition. They create a sense of …

Linking Variation In Mule Deer Nutritional Condition And Age To Population Performance In A Temperate Environment, Kent R. Hersey

All Graduate Theses and Dissertations, Fall 2023 to Present

The amount of body fat animals have as they enter and exit winter can have major impacts on how well they survive and reproduce. Mule deer are widely distributed herbivores whose survival and reproduction are strongly tied to weather patterns and the quality of vegetation they consume, which in turn impacts nutritional condition. The objective of this study was to identify and quantify the factors (animal specific, climatic, or habitat) influencing mule deer body fat during both summer and winter in Utah and examine how nutritional condition influences survival. We found December body fat was most affected by December lactation …

Additionally, a 2x2 typology categorizes distinct profiles of vulnerability to the Great Salt Lake based on different …

The Effect Of Voter Education On Behaviors In Ranked Choice Voting, Ethan G. Olsen

All Graduate Theses and Dissertations, Fall 2023 to Present

The appeal of ranked choice voting has led to its recent meteoric rise throughout America, leading to adoption in a number of cities and a handful of states, but some critics and political scientists worry about its higher difficulty potentially leading to more errors and undesirable behavior. Utilizing an experiment, I find that a short voter education video is all that is required to reduce rates of errors and ideologically inconsistent behavior, while finding null results for undervoting, possibly due to its low occurrence in the sample.

As ranked choice voting’s adoption is considered in each election cycle for jurisdictions …

Wild Water: Hydrosocial Dislocation, Dispossession, And The Symbolic Geographies Of The American West, Leonard Alexander Henderson

All Graduate Theses and Dissertations, Fall 2023 to Present

This dissertation investigates how the confluence of community change and water politics in the American West shapes a discussion about a Wild and Scenic designation for the Crystal River on Colorado’s Western Slope. Ideas about the “Wild West,” influence how many people think about wilderness and small mountain towns, driving growing populations, housing prices, and, as a result, social inequality in many of these areas. At the same time, many people on Colorado’s Western Slope feel that region’s water is taken away by both the state’s more populous Front Range or more politically and economically powerful states like California. Climate …

Balancing Native Wetland Types And Ecosystem Function Conservation In The Face Of An Aggressive Plant Invader, Aubin A. Douglas

All Graduate Theses and Dissertations, Fall 2023 to Present

Wetlands provide a multitude of ecosystem services that are important to people including water filtration, flood attenuation, carbon sequestration, and recreational opportunities such as birding and hunting. Wetland plants support these services by performing important underlying ecological processes called ecosystem functions which include removing heavy metals from water and providing habitat for migratory birds. The provisioning of these functions varies through space and time, by vegetation type, and via impacts from other factors like climate and management actions. Wetland managers are responsible for maintaining these functions and services within their management complexes to align with their agency’s mandates. Unfortunately, managers …

The Pharmacology Of Gpr171 Ligands In The Treatment Of Pain: An In Vitro And In Vivo Preclinical Characterization, Max V. Mcdermott

All Graduate Theses and Dissertations, Fall 2023 to Present

Opioids are addictive, ineffective for long-term treatment, readily produce withdrawal and tolerance, and can cause overdose and death. These properties have contributed to an epidemic of addiction and overdose, which continues unabated in the United States. Therefore, new drugs to treat acute and chronic pain are needed. Opioids bind to receptors belonging to a superfamily of proteins called G protein-coupled receptors (GPCRs). GPCRs are the most commonly targeted proteins among FDA-approved drugs. As such, under-researched GPCRs are a viable source of new targets in the field of drug development. One such underexplored GPCR is GPR171. Studies have demonstrated that a …
