Laboratory Measurements At The Impact Point Of A Falling Jet, Garrett Richins

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dams and spillways play a vital role in managing water resources. Many of these hydraulic structures feature a falling jet when discharging downstream. Engineers design plunge pools to receive jets with enough water depth or a protective liner to protect the river bottom so that scour is avoided. Quantifying the pressures at the bottom of the falling jet is a key component to determining the potential for scour and the need for mitigation techniques.

In the laboratory setting, significant discrepancies have been observed between different measurement methods to measure mean and fluctuating pressures of a falling jet intercepting a solid …

Volatile Cycling And Metasomatism In Flat-Slab Subduction Zones Of The Central Andes, Coleman Hiett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Flat-slab subduction, where an oceanic plate subducts horizontally below a continental margin for hundreds of kilometers, is an enigmatic but prevalent tectonic configuration in which chemical cycling and alteration of the continental plate is poorly constrained. Geochemical investigations in regions of modern and ancient flat-slab subduction in the Central Andes afford an opportunity to study this process. Certain elements naturally occur with varying number of neutrons in their nuclei (isotopes), and measurements of isotope ratios within geologic materials inform on chemical sources and geologic processes. This research leverages stable isotope analyses and other geochemical tools to investigate volatiles and other …

Population Physiology, Demography, And Genetics Of Side-Blotched Lizards (Uta Stansburiana) Residing In Urban And Natural Environments, Spencer B. Hudson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wildlife populations across the globe are poised to lose their natural habitat to urbanization, yet there is limited information on how different species handle living in cities. Animals in urban environments are often susceptible to novel stressors, which can threaten their individual health and population viability. The physiological characteristics of animals, such as those related to metabolic hormones, oxidative stress, and immunity, are expected to be important for survival in this context. If so, animals persisting in urban areas may demonstrate physiological differences from their natural counterparts, perhaps due to evolutionary change. These potential outcomes have been documented in birds …

Similarities And Differences In Correlates And Trends In Prescription Stimulant And Prescription Opioid Misuse Among College Students, Julie Murray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

When used as medically intended, prescription opioid and stimulant medications can have therapeutic benefits. Misuse of these medications, however, presents significant health risks, including increased risk of death and injury. Young adults, ages 18 to 25, have the highest rates of misuse of prescription opioids and stimulants nationally and within this age group, college students may be particularly at risk. This two-study dissertation explored factors related to prescription opioid and prescription stimulant misuse in college students in order to assess similarities and differences in correlates and trends.

Study #1 assessed for similarities and differences in correlates of prescription opioid misuse …

Overcoming Barriers To Aquatic Plant Restoration: Addressing Gaps In Species Identification And Planting Techniques In The Intermountain West, Kate A. Sinnott

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aquatic ecosystems provide many critical and economically valuable benefits, including drinking water, food, recreational opportunities, and water supply for irrigation and agriculture. However, the health of these systems has been severely impacted by human activities such as pollution, land conversion, and introductions of harmful species. Restoring native aquatic plants can help reverse this damage and reestablish benefits, though it is not a common practice. With an objective to increase capacity for aquatic plant restoration in the Intermountain West, I identified and addressed two major barriers: 1) a lack of confidence in aquatic species identification among wetland professionals, and 2) underdeveloped …

Generalizing Deep Learning Methods For Particle Tracing Using Transfer Learning, Shubham Gupta

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Particle tracing is a very important method for scientific visualization of vector fields, but it is computationally expensive. Deep learning can be used to speed up particle tracing, but existing deep learning models are domain-specific. In this work, we present a methodology to generalize the use of deep learning for particle tracing using transfer learning. We demonstrate the performance of our approach through a series of experimental studies that address the most common simulation design scenarios: varying time span, Reynolds number, and problem geometry. The results show that our methodology can be effectively used to generalize and accelerate the training …

Big Fish And More Of Them: Salmonid Habitat Availability, Quality, And Use Across Multiple Scales Within A River-Reservoir System, John S. Mclaren V

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reservoirs and their associated rivers provide water for agricultural and municipal uses, ecological benefits for fish and wildlife, and associated recreational activity. However, in the Greater Yellowstone Ecosystem climate change and population growth are putting pressure on water quality and supply, potentially damaging the unique and economically important coldwater trout habitat that these systems support. In this study, the author investigates the impact of changing water quality and supply on trout habitat quality, quantity, and selection to assist conservation goals in the Henry’s Fork Watershed in eastern Idaho. The study found that higher availability of cold-water refuge habitat in Island …

Durability Of Wireless Charging Systems Embedded Into Concrete Pavements For Electric Vehicles, Pilaiwan Vaikasi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The interest in electric vehicles (EVs) has been growing around the world significantly. EVs run on electricity by charging power to their batteries. However, a concern in the operation of the EVs is raised because they have an insufficient battery charge to reach their destination. In-motion, inductive power transfer (IPT) embedded into the roadway for the EVs can ease the need to use a charging stationary. This project focused on the durability of the dynamic charging IPT electronics integrated into concrete pavements. This research collaborated with electrical and mechanical engineering colleagues from the Advancing Sustainability through Powered Infrastructure for Roadway …

Investigating The Effect Of Greediness On The Coordinate Exchange Algorithm For Generating Optimal Experimental Designs, William Thomas Gullion

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Design of Experiments (DoE) is the field of statistics concerned with helping researchers maximize the amount of information they gain from their experiments. Recently, researchers have been turning to optimal experimental designs instead of classical/catalog experimental designs. One of the most popular algorithms used today to generate optimal designs is the Coordinate Exchange (CEXCH) Algorithm. CEXCH is known to be a greedy algorithm, which means it tends to favor immediate, locally best designs instead of globally optimal designs. Previous research demonstrated that this tradeoff was efficacious in that it reduced the cost of a single run of CEXCH and allowed …

Desert Body, Lauren Mckinnon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis is a collection of poems examining certain paradoxes of my body. As a survivor of sexual violence, my body relives trauma which makes it feel uninhabitable. I compare my experiences with the Southern Utah desert. The physical beauty, destruction and inhabitability of the desert teaches me to accept my body as both beautiful and full of grief. The poems move chronologically through my life, beginning with an abusive relationship at the age of sixteen, a move to Moab at nineteen, and becoming a mother at twenty-five. Ultimately, with the desert as my guide, I learn to accept my …

A Classification Of Tensors In Ecsk Theory, Joshua James Leiter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

You might have heard of Einstein’s theory of General relativity (GR): it is the one where mass and energy curve the fabric of spacetime to create gravity. This is the major theory which allows communication through satellites and our GPS to work too! Wormholes have interested me, but there are some issues about forming them in GR. Interestingly enough, elementary particles are also characterized by their spin in the standard model. However, intrinsic spin is nowhere geometrically coupled to the geometry of spacetime in Einstein’s theory. Later, Élie Cartan, Dennis Sciama, and Tom Kibble all flushed out adding different aspects …

The purpose of this meta-review is to establish a baseline dataset which is immediately utilized in my further research. …

The Sexual Objectification Experiences Of Non-Binary People, Lee R. Pradell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transgender people are a historically marginalized and disenfranchised group, leading to discriminatory interpersonal treatment such as sexual objectification experiences (SOEs), a type of objectification. Women look at themselves the way men look at them, reducing themselves to objects for someone else’s viewing. This flattening of oneself to value your bodily presentation over functioning increases dissociative states and promotes disordered eating behaviors. Non-binary people experience additive stressors within objectification experiences as people with less social power than cisgender women. This thesis is composed of three separate studies aimed at understanding the SOEs of non-binary people.

The first of three studies recruited …

Locating Low Head Dams Using A Deep Learning Model In Arcgis Pro With Aerial Imagery, Caitlin R. Arnold

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Low Head Dams are man-made structures that span the width of a river and allow water to flow over them. Although these structures vary in age and original purpose, some pose a life-threatening danger when recreationalists are entrapped in the reverse current at the toe. Despite these dangerous structures causing many drowning deaths in the USA each year, most low head dams do not have safety regulations and remain unknown to those charged with dam and public safety. Thus, to improve public safety at these structures, the first step is to fully inventory low head dams, so that subsequent efforts …

Relationships Between School, Teacher, And Feature Characteristics And Teachers’ Access To Features Within Digital Curriculum Resources For Mathematics Instruction, M. Jill Harmon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 2019, RAND Corporation asked teachers which digital materials they used. This study expanded on this research by exploring the features contained in these programs. The purpose of this study was to investigate the relationships between teachers’ access to features and school (e.g., grand band, socioeconomic status), teacher (e.g., experience), and feature characteristics (e.g., feature choice). I report a significant regression model to predict the likelihood for a teacher to have access to each of the six features within differing contexts based on the characteristics.

To answer the research questions, I first reported descriptive statistics as percentages of teachers who …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Family communication establishes expectations for a variety of behaviors, including emotion expression. This study explored if patterns of family communication were related to five behaviors that young adults might use to cope (drinking alcohol, watching TV, masturbating, eating, and exercising) via emotion regulation strategies. The data used for this study came from 504 young adults living across the United States who completed an online survey which asked them questions about how their family communicated when they were adolescents, their emotion regulation strategies, and how often they use the five coping behaviors listed above. The participants were between 18 and 30 …

Reimagining Culture With Youth: Relationship And Representation In Culturally Centered Learning Environments, Lili Yan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation intends to develop an understanding of how culturally centered learning environments impact youth’s relationship with culture. Working alongside a multicultural team of researchers, educators, and designers who came together with a shared goal of designing curricular activities to engage sixth graders with culture, I followed 12 sixth graders for a school year to understand their development of relationships with culture. I (re)conceptualize the holistic process of learning and engagement with culture as Ti-Wu and propose a cultural learning model that helps us understand how youth develop multiple relationships with culture. I further share how multimedia technology mediates youth’s …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Problematic and challenging student behavior has a myriad of negative outcomes for both educators and students. Although the implementation of Evidence Based Practices for classroom management have decreased these negative outcomes, educators are not utilizing them. The purpose of this study was to investigate which resources K-6 General Educators and Special Educators access to find information on behavior management strategies and procedures, as well as, their perceptions on those resources. We surveyed teachers from fourteen states in regards to what resources they used and the level in which they trusted, could implement, could understand and could find information on behavior …

Improved Sustainability And Efficiency Of Partial Depth Concrete Bridge Deck Repair, Israi I. H. Abu Shanab

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recently, significant advances have been made in the development of rapid setting cementitious materials for partial depth bridge deck repair. The rapid set times of these materials allow for traffic to be re-opened onto the bridge deck in several hours versus days once the material has been placed. While this is a substantial improvement in reducing the traffic closure time, a large amount of time is still spent on the removal of damaged and deteriorated bridge deck and in preparing the concrete cutouts for placement of the rapid set material. Partial deck removal is a much more delicate process than …

The Effects Of Recent Climate Change On Spring Phenology, With A Special Focus On Patterns Of Bee Foraging, Michael Stemkovski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The date on which plants flower and on which bees begin to pollinate varies year-to-year depending on differences in weather. This seasonal timing is known as phenology, and it is already clear that climate change has pushed the spring phenology of many species earlier by increasing temperatures. This is particularly clear in flowering plants, but studying how and why the phenology of pollinators is shifting is more difficult. Most flowering plants rely on pollinators such as bees for their reproduction, and most bees rely on flowers for their sustenance, so bee and flower phenology has to overlap for the crucial …

Fish Community Impacts And Conservation Implications Of A Novel Barrier On The San Juan River, Utah, Zachary T. Ahrens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Stream fragmentation and non-native species introductions are among a suite of anthropogenic disturbances shaping the structure and function of freshwater ecosystems. The impacts of such alterations contribute to the global decline of stream fish biodiversity and may be synergistic in their effects. For example, the Colorado River basin’s unique native fish assemblage is imperiled not only by numerous dams and diversions, but also by threats of predation and competition for limited resources from non-native fish species. On the San Juan River, Utah, a recently formed fish barrier prevents upstream movement of native and non-native fish. The goal of this project …

Tacitus, Barditus, And Odin's Eleventh Spell, Marie Skinner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Roman Historian Cornelius Tacitus wrote about native Europeans in 98 C.E., around a thousand years before the same peoples began recording their own history. Despite this, the work titled Germania is little-known and under-utilized. It is only by studying Germania and discussing it that the text will be seen for what it is and neither dismissed nor taken out of context. This thesis examines a few of the many passages of Germania that correspond with archaeological, literary, legal, and artistic information from later periods, demonstrating the value of Tacitus’ work to anyone studying European history.

Toward A More Holistic Understanding Of Uranium-Related Views And Experiences Of Residents In The Four Corners Region Of The United States, Matthew J. Barnett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on rural Four Corners Region (FCR) residents’ views about uranium production has focused mainly on predominately-White communities in the northern portion of the region. Meanwhile, residents in the southern part of the region, which includes the Navajo Nation and other tribal nations and communities, have dealt with the worst environmental and health effects of the uranium boom. Through a series of three studies in the southern part of the FCR, I explore the uranium-related views and experiences of racially diverse FCR residents.

In the first paper of this dissertation, I used 53 interviews to explore how sociodemographic factors (e.g., …

Ars, Virtus, Impetus: Gladiatorial Training And Roman Legionaries, Daniel Porter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 105 BCE, the Roman consul Publius Rutilius Rufus employed gladiatorial training for his legionaries. This thesis examines the physiological and psychological consequences of this style of training on the human body in an effort to understand why these particular soldiers were so effective. I used experiential testing alongside primary and secondary source research to examine how this process better prepared Roman troops for engaging in actual combat.

Opportunities And Challenges For Cooperative Extension Becoming A Major Actor In Climate Change Mitigation And Adaptation, Dakoeta R. Pinto

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Addressing climate change in the United States is an increasingly complex issue that requires social and technological changes throughout the country, which the Cooperative Extension System (Extension) can influence. Based at land-grant universities, their goals are to bring relevant science and innovation to the people of the United States. For a successful low-carbon transition, there are certain elements of society that must be influenced by innovators like Extension. Extension’s historical roots in agriculture prevail today with most of their programming focusing on this sector. However, there is a movement within Extension to expand their programmatic efforts to address more contemporary …

Probabilistic Verification For Modular Network-On-Chip Systems, Jonah W. Boe

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Modeling physical systems with formal analysis tools can help in the design of more fault-proof systems, by helping to determine if unpredictable or unwanted behavior may occur. Probabilistic verification further advances such processes, by providing quantitative information about the system. More complex systems can especially benefit from formal modeling and verification, as testing the physical system in every possible condition manually, can be extremely complex, and often impossible.

There is a growing interest in the application of Network-on-Chip (NoC) systems. NoCs can help simplify communication between the subsystems of many technologies, including the ever more complex multicore processors being produced. …

Comparing 1d, 2d, And 3d Hydraulic Models In Urban Flooding Applications, Taylor Kesler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Floods have been a hazard to people since people first started building near rivers. Predicting floods can be very beneficial to save lives and property. Computers have made it possible to solve fluid dynamics equations in a fast and efficient manner. Computer programs have been designed to solve these equations and create digital models of floods.

This study compares three different methods of computer modeling and explores their advantages and disadvantages. One-dimensional models solve fluid equations by setting up a series of cross sections. Two-dimensional models use a grid-like mesh to solve fluid equations from one cell to the next. …

Finding Their "Why": Examining The Development Of Sense Of Purpose During The University Years And Its Role In Student Well-Being, Michael Q. King

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nearly 20 million students were expected to be enrolled for college or university studies during the 2020-2021 academic year. These institutions often advertise to prospective students that, in addition to advancing their education, they will discover their purpose. Given previous work and current interest in sense of purpose, additional attention on sense of purpose in the university setting is worthwhile. In addition, as many university stakeholders are concerned about an ongoing mental health crisis, a further examination into a developmental construct (i.e. sense of purpose) thought to provide a “sheltering fortress in a world of constant threat” seems …
