The Evolution And Unraveling Of The American Eugenics Movement, Anneka Walton

Undergraduate Honors Capstone Projects

While the evolution of American eugenics surrounding the time of Nazi Germany has been well-documented, the periods before the explosion of American eugenics and the result of the movement in the wake of the Holocaust are not so well known. Many historically-based works have described the path and growth of eugenics from the time the term was coined to the public acknowledgement of World War II and the point where Americans ended eugenic euthanasia and slowed eugenic sterilizations. There are also many works within the realm of disability history that document these events from the more common social viewpoint. This …

Analyzing Suicidal Text Using Natural Language Processing, Cassandra Barton

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Using Natural Language Processing (NLP), we are able to analyze text from suicidal individuals. This can be done using a variety of methods. I analyzed a dataset of a girl named Victoria that died by suicide. I used a machine learning method to train a different dataset and tested it on her diary entries to classify her text into two categories: suicidal vs non-suicidal. I used topic modeling to find out unique topics in each subset. I also found a pattern in her diary entries. NLP allows us to help individuals that are suicidal and their family members and close …

Comparative Effects Of Eccentric Overload Training On Muscle Function Measures When Combined With Aquatic Plyometric Training, Cassidy Weeks

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Although there is a growing body of knowledge on eccentric resistance training and aquatic plyometric training on muscle function measures alone, no research to date has investigated the effects of a mixed training model. Aquatic plyometrics and overload eccentric training are two different training models which could work synergistically because the shortcomings of one model are the virtues of the other (i.e., plyometrics are not as effective at producing large muscle size and strength gains and eccentric-only training largely lacks the functional SSC component). The purpose of this study was to examine and compare the effects of a combined eccentric …

The Moth Effect, Kylie Smith

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This thesis is the start of what I envision to be a full-length memoir. I address multiple themes, specifically family and generational trauma and mental illness. I explore these themes non-linearly, through personal narrative, scientific research, and scene recreations. I begin with an introduction and then move into an essay that explores my experience meeting my estranged sister from the first time. Throughout the essay, I move in and out of this meeting, weaving the encounter together with my own struggles with mental health, research about the Peppered moth species, and scene recreations from the lives of other women in …

Relationship Of Eccentric Strength And Forward Perturbation Restabilization After Foot Contact, Leandra K. Ashworth

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Background: Forward falls are the most common fall direction and pose safety concerns for adults. To prevent forward falls, compensatory steps, and change-in-support reactions (e.g., foot contact) are critical for restabilizing center of mass after unpredictable, balance disturbances. Multi-joint, lower limb eccentric and isometric strength may provide additional insight on foot contact responses after a forward, temporally unpredictable perturbation. Multi-joint, eccentric muscular contractions have been found to result in significant neuromuscular adaptations (e.g., hypertrophy and muscular strength) and have higher retention capabilities than concentric contractions. Due to the importance of muscular strength in balance recovery, eccentric muscular strength could provide …

Development Of An Instructional Course On Fire-Protective And Low-Water Landscaping In Utah, Jordan Goff

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Because of climate change, population expansion, and other factors, both wildfire and drought are becoming pressing concerns in Utah. Home landscaping can reduce risk of damage from wildfire (fire-protective landscaping) and contribute to lower water use (low-water landscaping). While it is important for homes in the wildland-urban interface in Utah to have landscaping that is both fire-protective and low-water, best practices for the two are often taught in ways that make them seem mutually exclusive. This project used existing research and best practices to develop a learning experience to teach homeowners how to implement landscaping that is both fire-protective and …

The Effects Of A Mindfulness Curriculum On Sixth Grade Students In A Title I School, Jason A. Tackett

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Mindfulness is being integrated and studied across school settings as studies continue to reveal its beneficial effects. One of the largest mindfulness-in-schools organizations is Mindful Schools, which published a revised version of The Mindful Schools Curriculum for Adolescents (MSC-A) in 2019. While the effects of previous versions of the MSC-A have been evaluated in past studies and shown to be beneficial for students, the effects of the 2019 MSC-A have not been explored. This project sought to identify the effects of a condensed schedule of select lessons from the 2019 MSC-A on student and teacher perceptions of student mindfulness as …

Sacred Earth: The Role Of The Natural Divine Within Wendell Berry's "Manifesto", T. Greyson Gurley Ma

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Kentuckian writer and poet, Wendell Berry, is often associated with environmental literature and advocacy. However, often overlooked, much of Berry’s work is inherently religious in nature, specifically Christian. Berry’s poetry expresses many of his personal beliefs regarding life, spirituality, religion, interconnection, stewardship, and agriculture. In particular, Berry often uses characters to communicate these aforementioned personal ideas. This practice can be seen through his utilization of the character of the Mad Farmer within a great deal of his poetry, including poetry dedicated to the Mad Farmer himself. Although this character expresses many of the same beliefs as Berry, he is not …

Evaluating Plant Uptake Of 4,4'-Methylenedianiline, Jeff Wight

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

4,4’-Methylenedianiline (MDA) is an important industrial chemical used primarily in the production of polyurethane. It is toxic and a suspected human carcinogen. Polyurethane is used in a wide variety of applications such as furniture cushioning, coatings, adhesives, sealants, and elastomers. Polyurethane in soil may degrade and release MDA. This is concerning due to some models predicting a high potential for MDA to be taken up by plants and stored in edible tissue, creating a possible route of exposure for humans and animals. In this project, the potential for MDA to be take up by plants was investigated in order to …

Thermodynamic Analysis Of A Novel Cycle For Nuclear Smr And Heat Transfer Performance Validation Of The Related Supercritical Working Fluids, Benjamin M. Pepper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Currently, all operating nuclear power facilities in the U.S. follow the same general design and process: light-water reactors boil water into steam using bundles of nuclear fuel rods as a heat source, pumping that steam through a turbine which powers a generator to produce clean year-round electricity. Water is an effective coolant, but other facilities around the world have demonstrated the ability to use non-water-based coolants in nuclear reactor designs, which consequently have their own trade-offs. Some positive consequences of using different reactor designs include enhanced safety, better economics, and cheaper clean consumer energy. The work described in this paper …

Evaluation Of Human And Ecological Water Management Tradeoffs In A Seasonal Watershed With Spatially-Distributed Demands, Jesse Lee Rowles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

River managers must balance the needs of the ecosystems that rely on the river by leaving water instream, often while also considering human demands. It is especially difficult to balance these water needs in systems that are highly seasonal and have no instream storage (e.g., reservoirs) since water cannot be stored for use throughout the year. An example of a watershed that has both of these characteristics is the South Fork Eel River in coastal northern California. In order to evaluate tradeoffs between human and ecological demands in this system, a water allocation model with water management scenarios and environmental …

Carnivoran Frugivory And Its Effect On Seed Dispersal, Plant Community Composition, Migration, And Biotic Carbon Storage, John P. Draper

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seed dispersal by animals is important for the ecology of plants. It is particularly important to understand which animals are involved and how they move seeds differently from one another. Some seed dispersers are understudied despite ample evidence they consume fruits and seeds. This includes animals commonly referred to as carnivores in the order Carnivora. The overall goal of my dissertation was to describe the extent and quality of seed dispersal by Carnivorans, estimate important aspects of seed dispersal for a specific Carnivoran, the coyote, and estimate how differences between a coyote and songbirds affect where plants …

Artificial Intelligence And Deep Reinforcement Learning Stock Market Predictions, Andrew W. Brim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Billions of dollars are traded automatically in the stock market every day, including algorithms that use artificial intelligence (AI) techniques, but there are still questions regarding how AI trades successfully. The black box nature of these AI techniques, namely neural networks, gives pause to entrusting it with valuable trading funds. This dissertation applies AI techniques to stock market trading strategies, but it also provides exploratory research into how these techniques predict the stock market successfully.

This dissertation presents the work of three research papers. The first paper presented in this dissertation applies a artificial intelligence technique, reinforcement learning, to candlestick …

Voces: Experiences Of Undocumented Latines, José Manuel González Vera

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to learn about the challenges that this community faced before the pandemic and how they coped through those challenges. To answer this question, I examined transcripts from group interviews collected in the state of Texas. In total, there were 67 participants, many of whom were undocumented (n = 49) while the others had a relative or friend who was undocumented. Data were analyzed by looking for common patterns and themes in the transcripts, and guided by Critical Race Theory, Latine Critical Theory, and Undocumented Critical Theory. Results suggest that psychological distress is common …

4r Nitrogen And Water Optimization Combinations For Intermountain West Field Crops, Tina Sullivan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The concept of 4R (right source, rate, placement, and timing) management needs little introduction due to the surplus of nutrient studies in the literature for most cultivated crops. However, few studies have looked at these practices in the Intermountain West with nitrogen use, and fewer looked at 4R irrigation management. A survey was conducted to explore the interactions of nitrogen and irrigation management, test sensitivity to supply and price changes of nitrogen and irrigation for Utah and Idaho growers of small grains, corn, and potatoes, and determine the current adoption of precision agriculture options and identify the opportunities to improve. …

Cultivating Agrobiodiversity In The U.S.: Barriers And Bridges At Multiple Scales, Kaitlyn A. Spangler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The diversity of crops grown in the United States (U.S.) is declining, causing agricultural landscapes to become more and more simplified. This trend is concerning for the loss of important plant, insect, and animal species, as well as the pollution and degradation of our environment. Through three separate but related studies, this dissertation addresses the need to increase the diversity of these agricultural landscapes in the U.S., particularly through diversifying the type and number of crops grown. The first study uses multiple, openly accessible datasets related to agricultural land use and policies to document and visualize change over recent decades. …

Automated Quality Control For In-Situ Water Temperature Sensors, Leah S. Richardson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The identification of data not representative of the target subject for outdoor (in-situ) environmental sensors (bad data) is a topic that has been explored in the past. Many tools (such as data filters and computer models) have succeeded in providing an end user with properly identified incorrect data over 95% of the time. However, with the continuous increase in the use of automated data collection, a simple indication of the bad data may no longer provide the end user with enough information to reduce the amount of time that must be spent for manual quality control. The purpose of this …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation aims at discerning tourists’ behaviors and decision making processes for outdoor recreation participation, during the early COVID-19 pandemic. An outdoor recreation trip is defined in this study as “a journey involving at least one overnight stay away from home, and where the purpose is to engage in recreational activities in an outdoor or natural environment.” This dissertation first explores the factors that inhibit tourists’ desires for participating in outdoor recreation trips, the strategies they apply to avoid COVID-19 transmission, and the motivational factors that induce their desires for outdoor recreation participation in the COVID-19 context. The impact of …

Nutrient Uptake And Water Quality In Great Salt Lake Wetland Impoundments, Rachel L. Buck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Great Salt Lake (GSL) is the largest inland body of water on the Pacific flyway, a major pathway for migratory birds in the Americas that extends from Alaska to Patagonia. The lake is surrounded by approximately 360,000 acres of wetlands, providing critical food, shelter, cover, nesting areas, and protection to between 4–6 million birds that visit each year. Impounded wetlands were created as part of the GSL ecosystem to support waterfowl habitat. These large, shallow, submergent wetlands are diked to control water levels to sustain aquatic plants which are an important food source. Besides providing critical habitat, these impoundments …

Differential Transcriptome Analysis Reveals That Cache Valley Pm2.5 Triggers The Unfolded Protein Response In Human Lung Cells, Morgan Eggleston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Worldwide, exposure to air pollution is a serious human health threat. Particulate matter (PM) air pollution is a mixture of suspended solid and/or liquid particles and particle size is determined by its aerodynamic diameter. Fine, or “respirable” particles, typically from vehicle emissions, manufacturing, power generation, agriculture, as well as secondary photochemical reactions, are classified as ≤2.5μm in diameter (PM_2.5). Upon inhalation, PM_2.5 particles can reach the lower, more sensitive regions of the lung, enter the bloodstream, and be distributed to other areas in the body. Large-scale epidemiology studies have shown that PM_2.5 air pollution is associated …

What Keeps Technology And Engineering Teachers In The Classroom? A National Mixed Methods Study, Cory J. Ortiz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teacher retention is a significant issue impacting educational agencies around the country. Factors that have been found to be predictors of teacher retention include sense of belonging, sense of efficacy, and job satisfaction. Many personal and professional characteristics of a teacher also have been found to predict teacher retention. The purpose of this research was to explore how these factors predicted Technology and Engineering Educators' (TEE) teachers’ persistence to remain in the teaching profession. Furthermore, this research sought to identify programs that existed to help support TEE teachers in their persistence intentions.

This research found teacher job satisfaction was a …

The Effects Of Seed Mix Composition, Sowing Density, And Seedling Survival On Plant Community Reassembly In Great Salt Lake Wetlands, Rae Robinson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wetlands are known for their valuable benefits (e.g., providing habitat, improving water quality, lessening the negative impacts of drought and flooding). Invasive wetland plant species are species that cause harm to ecosystems, the economy, or human health, and replace native wetland plant communities. The revegetation of native plants may be one way to improve wetlands that have been impacted by invasive species. In Great Salt Lake (Utah, USA) wetlands, the invasive, non-native grass Phragmites australis (common reed) reduces the quality and quantity of habitat for both wildlife and humans (e.g., birdwatchers, waterfowl hunters). Even when P. australisis greatly reduced, native …

Assessing The Role Of Magnetite In Municipal Wastewater Treatment, Patricia Ayaa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Some municipal wastewater treatment (MWWT) facilities have adopted magnetite in their treatment processes through a technology called BioMag® to meet effluent regulatory requirements for total nitrogen and total phosphorus. However, there is limited information on the mechanisms and efficiency of magnetite in the removal of nitrogen (N) and phosphorus (P) from wastewater. This research, therefore, estimated its effectiveness in the removal of these nutrients, with a case study of the Marlay-Taylor Water Reclamation Facility in Maryland. The intervention analysis model was used, but a new forecasting approach to the model was proposed to fit the data in this study and …

Children's Mathematical Engagement Based On Their Awareness Of Different Coding Toys' Design Features, Joseph S. Kozlowski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tangible coding toys have been promulgated as useful learning tools for young children to learn computer science and mathematics concepts and skills. Although research shows coding toys can support mathematics for early childhood aged children, little is known about the specific design features of coding toys that afford mathematical thinking concepts and skills to young children. The purpose of this study was to examine kindergarten-aged children’s awareness of the design features in coding toys and to understand how those design features afford children’s engagement with mathematics. The dataset used for this study was collected as part of design-based research NSF …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This classroom-based research study explored applications of informal online spaces in formal language instruction. Using sociocultural theory as a lens, the present study examined how using creative writing genres and online feedback practices, may assist with alleviating the three pedagogical issues of academic writing instruction: rigidity of academic topics and forms, superficiality of in-class feedback process, and slow language development. Students in an intermediate English language course wrote weekly fiction inspired by their favorite video games. They also engaged in a scaffolded feedback process facilitated in an online space. At the end of the semester, they wrote a reflection on …

An Exploration Of Parent Management Training Programs And Their Cultural Relevance, Maria De La Caridad Alvarez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Behavioral parent training is a research-supported treatment for improving child behavior and increasing parenting skills. Despite many programs sharing a theoretical foundation and common elements, there is great variety in terms of treatment targets, populations served, treatment length, delivery setting, and expected outcomes. The purpose of this research was to first systematically organize and categorize relevant program information for the most frequently referenced Parent Management Training (PMT) programs. To this end, 19 programs were identified for review. We summarized each program and their available research evidence which ranged from 1 to 72 studies. The findings from this first project informed …

The Impact Of Covid-19 And Telehealth Services On Attrition Rates In Psychotherapy, Rylan B. Hellstern

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Clinicians in psychotherapy are constantly looking at their outcomes in order to identify and remove barriers that may inhibit effective treatment. Defined generally as the ending of a treatment prior to proper optimal benefit, attrition has been found to both hinder treatment efficacy and cost-effectiveness in therapy. While most attrition literature focuses on the contributing factors to such premature termination, little to no research is available that discusses potential resources for attrition rates. The COVID-19 pandemic has resulted in the use of telehealth services which may serve as a resource to combat attrition. The current study aims to identify how …

Detecting Ecosystem Response To Restoration Efforts With Implications For Recovery Of The Threatened June Sucker (Chasmistes Liorus) In A Shallow, Eutrophic, Utah Lake, Ryan D. Dillingham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Environmental damage associated with a growing human population will increase globally without active management. Restoration can promote ecosystem recovery, yet often fails to produce desired results and may require decades to achieve noticeable benefits. Detecting small, incremental change sis imperative in these difficult situations. Here, I demonstrate that restoration focused on fish removal triggers incremental responses in aquatic plants and animals. Removing common carp is expected to encourage recovery of aquatic plants, increasing animal habitat, resulting in more macroinvertebrates (e.g., aquatic insects, snails). Carp removal should also increase water clarity, improving visibility for fishes, thus increasing their ability to find …

'I Try To Take The Whole Family Thing Out Of The Picture': How Professionals Navigate Motherhood Bias At Work, Rachael Gulbrandsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research aims to improve our understanding of professional mothers and the strategies they develop to navigate bias and sustain their careers. Previous research has shown that women with children face a motherhood bias that results in negative career outcomes such as reduced wages, fewer high-quality assignments, and decreased chances for promotion and leadership opportunities. This research investigates how professional mothers respond to that bias by analyzing interviews with forty-seven women in the field of law about their professional experiences: their experiences before and after having children; the challenges they face navigating their careers and families; and the strategies they’ve …
