A Systematic Review Of Acceptance And Commitment Therapy In Sub-Saharan Africa: Understanding The Cultural Adaptations, Miriam N. Mukasa

All Graduate Theses and Dissertations, Fall 2023 to Present

Acceptance and Commitment Therapy (ACT) is a type of therapy that helps people handle difficult thoughts and feelings by staying present, accepting what they cannot control, and focusing on what truly matters to them. Despite its growing global popularity, the implementation and effectiveness of ACT in sub-Saharan Africa remains underexplored.

We evaluated the current evidence on the application, effectiveness, and cultural adaptation of ACT in sub-Saharan Africa, identifying gaps and providing recommendations for future research.

18 unique studies that met the inclusion criteria were found. Studies on improving athletic performance were the most common, with ACT also being evaluated for …

A Voice For Unity: The 1947 Freedom Train And Collective Memory Of The American Revolution, Joseph Lewis

All Graduate Theses and Dissertations, Fall 2023 to Present

One element of American Revolution memory is how united the colonists were during the Revolution. Many subsequent political groups, such as the American Heritage Foundation (AHF), utilized this idealistic collective memory to advocate for unity and legitimize their agendas. Through the 1947 Freedom Train, the AHF shaped and reinforced a unified, idealistic, national heritage to unite Americans against the perceived threats of communism, disloyalty, and disunity at home, partially by framing the American Revolution as a united endeavor. Some Utahns and Americans at large, while supporting the pro-capitalist message embedded in the train, applied its message to support the protection …

Lidar Scene Reconstruction Using Imagery And Frame Overlap From A Texel Camera, Blake Chamberlain

All Graduate Theses and Dissertations, Fall 2023 to Present

A small unmanned aerial vehicle (sUAV) can be used to reconstruct a large area of terrain by capturing 3D scans, consisting of LiDAR point clouds and an overlaid image, and combining the scans together. Forming a complete 3D scene using texel image data (fused LiDAR and digital image scans) from an entire flight can be computationally prohibitive on low-cost hardware, so combining registering scans is done using a streaming method which processes the scans in consecutive chunks. Depending on the flight pattern, matching points in the scene may be visible from scans which were not captured around the same time, …

A Laboratory Study On The Hydraulics Of Stepped Spillways: Effects Of Step Geometry And A Labyrinth Crest, Megh Raj K C

All Graduate Theses and Dissertations, Fall 2023 to Present

Observed trends in extreme storms are affecting the safety of several embankment dams. Spillways are critical for safely conveying excess water in the reservoir over the dam and into the downstream river, yet many dams that were built over 40 years ago have undersized spillways to handle modern flood estimates requiring repairs and upgrades. Consequently, a unique spillway crest, the labyrinth weir, has been used as a cost-effective improvement for numerous projects to enhance discharge capacity of existing weirs. Another cost-effective option for overtopping protection due is to place a less expensive concrete, Roller-Compacted Concrete (RCC), over the dam to …

Screening Of A Diversity Of Legumes And Non-Legumes Forb Species At Five Strategic Locations Across Utah For The Development Of Smart Foodscapes, Surbhi Verma

All Graduate Theses and Dissertations, Fall 2023 to Present

Grass-dominated rangelands in the Western United States often lack sufficient protein for pregnant cows after grasses mature in mid- summer, leading ranchers to rely on expensive feed supplements such as protein cubes or alfalfa hay. The goal of this study was to screen 27 perennial legume and forb species with the potential to remain green into late summer and provide sufficient protein to supplement cows on grass-dominated rangeland. Three experiments were carried out to understand germination of species, plant establishment and persistence at five Utah locations, and agronomic characteristics. The seed of five hard-to-germinate species were studied for the ability …

Forging Resilient Futures: The Role Of Community Organizations In Addressing Environmental Injustices Faced By Immigrants Along The Wasatch Front, Utah, Nowrin Fatema

All Graduate Theses and Dissertations, Fall 2023 to Present

Utah’s Wasatch Front is an urban area with a growing population that faces looming environmental challenges, such as the desiccation of the Great Salt Lake, worsening air quality, water scarcity, and the impacts of urban sprawl. If not prevented, the lake’s desiccation or other environmental challenges could result in dangerous air pollution, biodiversity loss, and disruptions to local economies. Immigrant populations may be uniquely vulnerable to these environmental changes because of economic, social, and political marginalization. For example, 50% of Salt Lake City’s foreign-born residents live on the City’s westside—the area on the frontline of the lake’s toxic dust. My …

Gone With The Flow: Flow Reduction Coincides With Reduced Metabolism And Standing Stock Of Benthic Algae And Macroinvertebrates In Desert Rivers, Chloe E. Lyles

All Graduate Theses and Dissertations, Fall 2023 to Present

River metabolism, the measure of energy flow in a river, is driven by hydrological and physicochemical regimes (e.g., temperature, turbidity, and nutrients). However, these regimes are increasingly altered by human water demand and climate change-driven drought. These stressors alter the magnitude, timing, and duration of critical spring-snowmelt floods with poorly understood consequences on ecosystem function, particularly in desert rivers. To investigate the linkages between flow reduction, river metabolism, and basal food resource productivity (i.e., algae and aquatic invertebrates), we measured metabolism and basal resource availability in seven desert tributaries with varying degrees of flow reduction during low-flow conditions in 2023 …

Learning Intentions, Success Criteria, And Metacognition: The Influence Of A Professional Development For Grades Three To Five Teachers, Jason Hart

All Graduate Theses and Dissertations, Fall 2023 to Present

Formative assessment is a strategy that teachers use to improve student learning. This study explored how professional development focused on assessment for learning practices (AFL), with the main emphasis on learning intentions and success criteria, influences teacher use of those strategies and changes in teacher and student metacognition. The overarching research question was: How does professional development on AFL practices influence teachers' reported use of AFL practices and teacher and student metacognition? This study utilized a mixes-methods research design and provided professional development on AFL practices to 16 in-service elementary mathematics teachers and measured changes to their AFL practices and …

Understanding The Impact Of Colloidal Calcium Phosphate On The Ph Variation In Cheddar Cheese During Early Stages Of Aging, Rachel Lindstrom

All Graduate Theses and Dissertations, Fall 2023 to Present

The Cheddar cheese industry has recently observed variation in the pH of their cheese during the early stage of storage. This variation may be due to the addition of the faster acid producing thermophilic starter culture Streptococcus thermophilus which was recently introduced into the Cheddar cheese making process. This starter culture may impact the calcium buffering properties of the cheese due to more retention of the insoluble calcium (INSOL Ca) within the cheese. To investigate this problem, we studied how insoluble calcium affects cheeses with pH ranging from 4.8 to 6.6 and found that INSOL Ca was positively correlated with …

Maximizing Dryland Seed-Based Restoration Success Via Retrospective Analyses Of Species-Use Patterns And Field Testing Of Seed Mix Composition, Spencer J. Good

All Graduate Theses and Dissertations, Fall 2023 to Present

Due to harsh and variable environmental conditions, successful plant establishment in "dryland" ecosystems – areas with scarce precipitation – is a major challenge for restoration. One of the most important decisions influencing restoration outcomes is choosing which species to plant (i.e., species selection). Here I explored two opportunities to improve restoration success related to species selection. First, I examined recent restoration projects across Utah, USA to understand species selection patterns by site conditions (e.g., precipitation, elevation) and seed costs, and to identify tools for matching species to sites. Second, I tested how commonly used non-native species – those not originally …

Component Analysis Of Interactive Computer Training To Teach Paraprofessionals To Deliver Behavioral Skills Training, Scott V. Page

All Graduate Theses and Dissertations, Fall 2023 to Present

In education and Applied Behavior Analysis, there is growing demand for well-trained entry-level individuals to deliver behavior interventions. Interactive Computer Training allows trainees to access online instruction with video demonstrations, interactive tasks, and feedback, without a live instructor. This training approach could save valuable training time and money. Prior researchers demonstrated these types of training can teach trainees to correctly use behavior interventions. There are gaps in our understanding of Interactive Computer Trainings that limit its successful use. Few studies measured cost-effectiveness, identified the effective features of Interactive Computer Training (e.g., videos, quizzes, feedback), or trained users to deliver effective …

Talkin’ Bout A Revolution: A Comparative Analysis Between Hannah Arendt And Frantz Fanon, Nicholas Gleed

All Graduate Theses and Dissertations, Fall 2023 to Present

What is the role of freedom and violence in revolution? This thesis involves a comparative analysis of how two major political theorists – Hannah Arendt and Frantz Fanon – understood and conceptualized the role of violence and freedom in relation to revolution. Due to their differing theoretical frameworks and perspectives, they often come to different conclusions on these points of comparison. However, by placing these two thinkers in conversation with each other, we can better understand the core of their arguments on freedom, violence, and revolution and how they might be similar and different in various ways. For Arendt, violence …

Desert Drowning: A Short Story Collection, Steve Shumway

All Graduate Theses and Dissertations, Fall 2023 to Present

As many young men born in Utah, I grew up Mormon, a member of the Church of Jesus Christ of Latter-Day Saints. While this is not out of the ordinary in this state, my connections within the history of the church were. My grandfather's great grandfather Charles Shumway was one of the first Mormon settlers to cross the plains and settle in what would become the state of Utah. Not only that, he was one of Brigham Young's most trusted lieutenants, instructed to scout ahead of the main wagon trains, and later settle parts of Northern Arizona, where the town …

Conservation Laws For Asymptotically Perfect Fluid Spacetimes, Lyle Arnett Jr.

All Graduate Theses and Dissertations, Fall 2023 to Present

In physics, conservation laws, like those for energy or momentum, are powerful tools that help us understand how systems evolve and interact. In general relativity, where spacetime itself is curved by matter and energy, defining such conservation laws becomes especially subtle and complex. Traditional methods rely on idealized conditions like empty space or special symmetries, which limit their usefulness in more realistic, dynamic settings such as an expanding universe.

This dissertation explores a modern mathematical framework, developed by Iyer and Wald, that allows conservation laws to be derived directly from the equations governing spacetime. Using this approach, I examine not …

By United States Congress mandate, NASA must discover more than 90% of all asteroids and comets that are larger than 140 meters in diameter and could potentially impact Earth. NEO Surveyor will provide critical decision support for stakeholders who must assess the risks of NEO impacts to Earth and identify potential mitigation strategies. …

A Systematic Review: Learning Emotion Regulation With Virtual Reality, David Boyd Bobo

All Graduate Theses and Dissertations, Fall 2023 to Present

This systematic review explored how immersive virtual reality (IVR) can help people manage emotions like stress and anxiety by analyzing existing studies. It highlighted therapies such as mindfulness, compassion therapy, and exposure therapy, showing how IVR can teach effective emotion-regulation skills. Researchers also identified innovative tools, like biofeedback, which uses physical signals such as heart rate to help people understand and control their emotional responses.

Interactive and gamified approaches, like Stressjam and Deep, demonstrated practical uses of IVR for mental health support. While the review confirmed IVR's potential in therapy, it also revealed gaps in research, particularly in applying …

On The Multi-Modal Psychological Experience Of Competence In Youth Sport, Liam O'Neil

All Graduate Theses and Dissertations, Fall 2023 to Present

Over the past half century, beliefs about athleticism (i.e., sport competence) have been thought of as central to motivation for youth sport. In this time, however, these competence beliefs have been narrowly studied which has limited their value in explaining youth sport participation. To expand our understanding of competence beliefs and their motivational significance in youth sport, the three studies of this dissertation tested a longstanding but understudied idea that competence beliefs encompass both judgments of, and emotions about, competence. In Study One, existing research on judgments of competence in youth sport was reviewed. This study showed that many personal …

Agrichemical Surfactant And Pathogen Impacts On The Blue Orchard Bee (Osmia Lignaria Say, Hymenoptera: Megachilidae), Mary-Kate F. Williams

All Graduate Theses and Dissertations, Fall 2023 to Present

Pathogens that infect commercially reared bee species, such as honey bees and bumble bees, have been extensively studied within the last several years, and studies that explore pathogen impacts on solitary bee health are significantly fewer. Consistent pesticide exposure methods are limited to honey bees and do not outline exposure routes to solitary bees, including how to test chemical impacts on immature stages. My research investigated blue orchard bee survival, development, and immune response following pathogen exposure while simultaneously studying organosilicone surfactant (OSS) exposure and possible synergisms between these two stressors. In my first research chapter (Chapter 2), I define …

Attachment, Emotional Experiencing, And Physiological Response During Couple Interaction, Kyla Iverson

All Graduate Theses and Dissertations, Fall 2023 to Present

In this master’s thesis, I conducted a study using data from 63 hetereosexual couples from a previous research study done by Dr. Ryan Seedall. These couples participated in a micro-intervention where each partner discussed personal issues for three to four minutes while the other received guidance on supportive responses, promoting open communication. Using this data, I conducted a coding project studying the relationship between attachment styles and emotional experiencing, specifically how attachment styles intersect with emotional experiences, moment-to-moment feelings, and physiological arousal. This coding project involved utilizing the Emotional Experiencing Scale (EXP) by Klein and colleagues (1986) to observe couple …

All Graduate Theses and Dissertations, Fall 2023 to Present

American civic education continually proves to need attention and reform. This research evaluates whether implementing specific teaching strategies at the high school level impacts a student's future political participation; specifically, to more clearly outline whether a high school level civics curriculum directly impacts a student's likelihood to cast a voting ballot in midterm and presidential elections within six years of graduation. This paper aims to understand better if teaching and/or education reform is effective in helping future generations and the democratic fate of our country. In this study, we measure the current state civic graduation requirements compared with the state's …

Dissemination Trial Of Provider Training Of Act-Enhanced Behavior Therapy (A-Ebt) For Trichotillomania: A Waitlist Controlled Study, Mercedes G. Woolley

All Graduate Theses and Dissertations, Fall 2023 to Present

Trichotillomania is a mental health disorder where individuals compulsively pull on their hair, leading to distress and life challenges. Although effective treatments like habit reversal training (HRT) and ACT-enhanced behavior therapy (A-EBT) exist, many health providers lack knowledge about these approaches. This study aimed to close that gap by training therapists in A-EBT through an online workshop and follow-up consultations. Over 100 therapists participated, and those who completed the training gained more knowledge about trichotillomania, felt more confident in their ability to treat the condition, and were more likely to promote their services, leading to more people getting the care …

Calculation Of Aerodynamic Surface Sensitivities Using The Adjoint Method In A Subsonic/Supersonic Panel Code, Nathan H. Hoch

All Graduate Theses and Dissertations, Fall 2023 to Present

An aircraft’s shape has a direct impact on the lift and drag it produces. In the early stages of designing an aircraft on a computer, engineers work to improve aircraft performance and efficiency by considering various shapes and configurations. Engineers use computer programs to analyze different designs and predict how each would perform in real-world conditions. Once an approximate aircraft shape is selected, adjustments to the shape can further improve the aircraft’s lift and drag characteristics. Engineers calculate a set of values called sensitivities that indicate which parts of the geometry should be changed to increase lift or reduce drag. …

Leadership, Identity, And Student Voice In Secondary Schools, Gordon S. Geddes

All Graduate Theses and Dissertations, Fall 2023 to Present

Many student leadership programs in U.S. high schools operate without clear guidance, often leaving students as passive participants in systems that may not effectively prepare them for leadership roles both in school settings and elsewhere. This study explores how listening to students’ voices can improve leadership programs by better understanding how young people see themselves as leaders. Using a case study approach at one school, I observed student leaders over one school year and analyzed their experiences through leadership development theories. The findings suggest that when schools take students' perspectives into account, they can create leadership programs that are more …

Contrastive Representation Learning For Highly Imbalanced Multivariate Time Series With Extreme Instance Strategy, Onur Vural

All Graduate Theses and Dissertations, Fall 2023 to Present

Time series data refers to a sequence of data points collected or recorded at regular time intervals. In many fields including space weather, healthcare, and finance, predicting events from such data is crucial because these predictions can help protect infrastructures, improve healthcare outcomes, and forecast financial trends. However, one challenge in working with time series data is the presence of rare events, which are often underrepresented in the data. This imbalance makes it difficult for traditional prediction methods to provide accurate results, as they tend to focus more on the more frequent events and overlook the rare ones. To tackle …

Disentangling Factors Contributing To Population Performance Of Zion Bighorn Sheep, Ian Montgomery

All Graduate Theses and Dissertations, Fall 2023 to Present

Bighorn sheep populations across the western United States face increasing challenges from habitat loss, disease, and predation. In Zion National Park and surrounding areas, survey-based estimates indicate that the desert bighorn sheep population declined from over 800 individuals in 2018 to fewer than 500 in 2021. Understanding what drives these population changes is critical for effective wildlife management and conservation. This research examined key factors influencing population growth and individual survival to inform strategies for recovery in this bighorn population.

First, we analyzed which vital rates contributed most to population trends by estimating survival and reproduction rates from ground and …

Critically Assessing Normative Methods And Their Limitations In Managing Crowding Within Parks And Protected Areas, Glendon R. Vansandt

All Graduate Theses and Dissertations, Fall 2023 to Present

Visitor experiences in parks and protected areas are shaped by a variety of environmental, managerial, and social factors. To ensure that visitors enjoy their time in these spaces, management agencies often adopt guidelines to establish acceptable levels for different aspects of these experiences. One of the most selected factors is perceived crowding, which reflects how crowded visitors feel in a given area. When perceived crowding exceeds desired levels, it can significantly diminish visitor satisfaction.

This thesis presents two studies aimed at identifying the shortcomings of the management of perceived crowding. The first study conducts a comprehensive literature review that identifies …

Caregiver Implemented Standardized To Individualized Behavior Analytic Toilet Training Package For Autistic Preschoolers, Jessica A. Osos

All Graduate Theses and Dissertations, Fall 2023 to Present

Autistic children often face challenges with toilet training and may benefit from a more structured and systematic approach compared to methods used for neurotypical children. While research and literature in this area has shown that behavior analytic toilet training packages can lead to increasing successful urinations and reducing accidents for autistic children, limitations such as not including caregivers as the individuals implementing the package, unsustainable sit schedules, and lack of acceptable levels of checks for accurate data collection and implementation of procedures highlight the need for refining of implementation oversight and examination of updated toileting procedures without the use of …

Investigating Stability Of Cone-Derived Hypersonic Waverider Vehicles Via Design Space Exploration, Adam S. Weaver

All Graduate Theses and Dissertations, Fall 2023 to Present

It may come as no surprise that man-made objects flying at 5, 10, or even 25 the speed of sound (termed hypersonic) are difficult to design, inefficient in flight, and expensive to deploy. Most hypersonic vehicles are effectuated in ballistics, which simplify aerodynamic considerations owing to their fixed trajectory. However, maneuverable hypersonic vehicles can revolutionize commercial flight, national defense, and space travel. One candidate for such missions are waverider vehicles. Waverider vehicles cruise on a cushion of air generated by its own shock wave, essentially enjoying extra lift without any extra drag penalties (which are usually inherent to extra …

Water Use By Irrigated Turfgrass And Connections To Climate And Biophysical Processes, Karem Meza

All Graduate Theses and Dissertations, Fall 2023 to Present

Urbanization and limited water supply and storage result in imbalanced urban water budgets. Quantification of water use becomes important in urban landscapes because urban turfgrass requires a significant amount of water and competes with other urban requirements. Evapotranspiration (ET) plays a crucial role in determining irrigation needs. Credible measurements and spatial estimates of urban turfgrass ET are needed for urban water management. However, these have not been addressed in urban landscapes in arid and semiarid regions. Despite estimating spatial urban turfgrass ET, turfgrass quality linked to ET has not been widely evaluated. Due to different environmental conditions, the driving forces …
