All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to explore the adulthood transition experiences of Utah high-school graduates, with heightened focus on the application value of educational content from the course, Adult Roles. The purpose of the study was identified through experiential interactions with high-school graduates, and was supported by research on 21st century adulthood transitions shown to divert away from traditional adulthood markers. The inconsistency between modern adulthood transition behaviors and traditionally held adulthood assumptions lead to negative perceptions about young adult’s capability to adapt to adulthood. The researcher was motivated to investigate opportunities that may provide increased preparation for the transition into …

Reducing Thermal Bridging And Understanding Second-Order Effects In Concrete Sandwich Wall Panels, Taylor J. Sorensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Structural engineers have traditionally detailed structures with structural and fabrication efficiency in mind, but often based on a limited understanding of thermal efficiency. Some connection designs can create significant thermal bridging, leading to unnecessary heat transfer and even premature degradation through condensation. Thermal bridging occurs when heat transfer is given a path through a more conductive material like concrete or steel rather than insulation. Concrete sandwich wall panels (SWP) tend to be highly efficient at preventing heat transfer in the middle of panels, with greatest heat transfer occurring at connections. This project identified thermally efficient details for future SWP construction …

The Influences Of Calculus I On Engineering Student Persistence, Amie Baisley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

About half of the students that are declared engineering majors end up leaving engineering within their first two years at the university. This happens following the required math and science courses that these students must take before getting into the technical engineering coursework. There are two systems that students must be a part of at the university to feel comfortable and have the desire to continue on in their degree. These include the academic system and the social system. The experiences engineering students have during their first required math course, Calculus I, is likely not promoting integration into these two …

The Relationship Between Small-Group Discourse And Student-Enacted Levels Of Cognitive Demand When Engaging With Mathematics Tasks At Different Depth Of Knowledge Levels, Kristy Litster

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

High cognitive demand (HCD) tasks can help students develop a deeper understanding of mathematics. Teachers need interventions that encourage students to engage in HCD activities. Small-group discourse provides HCD opportunities for students while solving mathematics problems. Discourse can take place after students solve problems individually (reflective) or in groups as students solve problems (exploratory). This study looks at the relationship between these two types of small-group discourse and student-enacted cognitive demand.

This study looks at how students engage with tasks that were designed at four different cognitive demand levels using Webb’s depth of knowledge (DOK) framework. Ninety-seven grade 5 students …

Preschool Science: An Examination Of Classroom And Teacher Predictors, Donna S. Blaylock

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Science experiences during the preschool years is important because it helps build brain development in children, and improves school readiness. This exploratory study examined several characteristics of teachers and classrooms to see if any factors predicted time spent on science. Over 120 teachers participated, with teachers from Head Starts, university child development laboratories, home-based preschools, and other private preschool programs.

Findings suggest that preschool teachers are quite comfortable with teaching science, but science activities are reported to occur infrequently—one to three times a month. Teachers with higher levels of education and comfort levels with science are reported to be more …

Development And Testing Of A Hydrogen Peroxide Injected Thrust Augmenting Nozzle For A Hybrid Rocket, Mark C. Heiner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

During a rocket launch, the point at which the most thrust is needed is at lift-off where the rocket is the heaviest since it is full of propellant. Unfortunately, this is also the point at which rocket engines perform the most poorly due to the relatively high atmospheric pressure at sea level. The Thrust Augmenting Nozzle (TAN) investigated in this paper provides a solution to this dilemma. By injecting extra propellant into the nozzle but downstream of the throat, the internal nozzle pressure is raised and the thrust is increased, and the nozzle efficiency, or specific impulse is potentially improved …

Staff Perceptions Of Quality Interactions In Dementia Care, Rebecka A. Schultz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The national aging trend suggests that population of those aged 65 and older will reach 83.7 million by the year 2050. With increasing age comes the growing possibility of one getting some form of dementia. The Alzheimer’s Association expects the number of American’s with dementia to triple from the reported 5 million cases in 2014 by 2050. With a rise in this cognitively impaired population there is reason to look closely at the needs of persons with dementia living in residential facilities and whether or not they are being met. The main focus of residential facilities is to provide aid …

In Defense Of The Modern Company Town: Wyoming's Uranium Communities, Zachary R. Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Most people are at least aware that, in the past, companies that owned mines, lumber mills, and other large-scale industrial projects in isolated areas also ran company towns. For many people, such towns conjure up images miserable working conditions, exploitative company stores, and inadequate shacks for most workers, while managers live in relative luxury up on “snob knob.” Most people are also fairly certain that such towns, at least in the United States, died out about the same time as the horse and buggy. Several industries in Wyoming, however, continued to support company towns through the end of the 20th …

Gpu-Accelerated Demodulation For A Satellite Ground Station, Emily Clark Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One consequence of the increasing number of small satellite missions is an increasing demand for high data rate downlinks. As the satellites transmit at high data rates, ground-side receivers need to demodulate the transmitted data as quickly as possible. While application specific hardware can be designed, software defined radio solutions for ground stations are attractive for their flexibility, adaptability, and portability.

Another industry trend is the increasing use of Graphics Processing Units (GPUs) in general-purpose processing. By performing many operations simultaneously, GPUs are capable of accelerating processing when given a problem that can be implemented in a parallel manner. Furthermore, …

Activity Tracker Measurement Of Physical Activity And Sedentary Time In The Workplace Including An Intervention Involving Reminders To Move, Cassie Dance

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sedentary time and physical inactivity have negative impacts on health and health costs as well as an impact on workplace wellbeing. There is evidence that people are more sedentary and engage in less physical activity on work days. Additionally, sedentary behavior has been found to increase distress and negative mood. Activity trackers such as Fitbits are a useful way to collect and intervene on sedentary behavior and potentially impact other factors of workplace wellbeing in real time and promote self-monitoring. The reminder to move prompts that are now part of Fitbit models provide an innovative and simple way to intervene …

The Determinants Of Municipal Minimum Wage Ordinances: An Analysis Of 100 Large Cities From 2012-2017, Nicholas S. Hilton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The city of Seattle, Washington made headlines in 2014 when its city council enacted the highest minimum wage in the history of the United States. The ruling appeared to begin a trend as similar policies began diffusing in cities across the country. In reality, however, municipal minimum wage ordinances have existed since the early 1990’s. Yet, despite over two decade’s worth of data on the subject, little research has been conducted to understand the characteristics that influence cities to enact minimum wages in the first place. This study contributes to our understanding of the predictors of minimum wage ordinances by …

Public Transportation Accessibility: Perceptions Of Riders With Disabilities In Utah, Cherissa R. Alldredge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Transportation plays an essential role in social inclusion and participation, subjective well-being, and overall quality of life. A lack of private transportation options may make individuals with disabilities more dependent on public transportation systems. Despite increased use, people with disabilities continue to report barriers accessing public transportation services. Interestingly, little is known about these barriers at the regional transportation district level. The purpose of this study was to better understand the barriers and perceived accessibility of the Utah Transit Authority’s (UTA) public transportation system for individuals with disabilities living within the UTA service area.

Using an online survey, data were …

Since then, the Research Service Group (RSG), conducted a new study in 2012 to understand current travel preferences in Utah. This survey, called the Residential Choice Stated Preference survey, asked respondents to make ten choice comparisons between two hypothetical homes. Each home in the choice comparison was described by different attributes, those attributes that were used are, type of neighborhood, distance from …

The Role Of A Peer-Led Academic Intervention In College Students' Development Of Self-Regulated Learning: A Person-Centered Approach, Soojeong Jeong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to its unsupervised nature, undergraduate education requires students to manage their own learning. They need to use self-regulated learning (SRL) strategies in order to achieve academic success. However, college students often have insufficient regulatory skills and strategies, suggesting the need for substantive and practical support. Supplemental Instruction (SI) is a well-recognized academic intervention that utilizes peer-led study groups for difficult college courses, through which students can develop their SRL abilities.

This study focuses on the role of the SI program in college students’ development of SRL from a person-centered perspective. First, this study examines the heterogeneous effects of the …

Career Prospects And Resources Of Domestic Engineering Doctoral Students, Laura A. Gelles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Career prospects are a motivating factor for entry and retention of doctoral students, especially in the discipline of engineering. While doctoral student training provides them with highly specialized skills to be an independent researcher, they may not have the requisite skills or guidance to secure the job position of their choice. Therefore, it is important to provide doctoral students with opportunities, training, and information (i.e., resources) about different types of careers to not only ensure they are productive contributors of teaching and research, but also equip them for future career prospects. Research techniques based upon in-depth narrative interviews and combining …

Enteric Methane And Nitrogen Emissions In Beef Cattle Grazing A Tannin-Containing Legume Relative To Feedlot And Traditional Pasture-Based Production Systems, Raúl David Guevara Ballesteros

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Beef cattle production is highly criticized because of the high use of land and water resources, and by the pollution (e.g., the gas methane in a cow’s breath and nitrogen in urine) produced by cows fed in feedlots. In contrast to feedlots diets and grasses, some plants (e.g., legumes) contain bioactive compounds (condensed tannins) that reduce pollution and enhance animal nutrition. In my research, I observed that cows grazing a tannin-containing legume (birdsfoot trefoil; BFT) had methane emissions similar to cows fed a feedlot ration with comparable weight gains. Cows in the BFT treatment gained more weight than cows grazing …

The Bureau of Land Management (BLM) manages approximately 245 million acres in the U.S., the majority of which are in the western half of the country. There have been several conflicts in Nevada, Oregon, Utah, and Arizona, since 2010 that have resulted in a fatality, armed militias, several incarcerations, and lawsuits facing the federal government. Following a preliminary needs assessment conducted in Box Elder County, Utah, and a comprehensive review of the literature, further research was needed to understand BLM professional (BLM managers or BLM specialists) and rancher perceptions regarding BLM policies and procedures. The study specifically looked at attitudes, …

Coaching Parents To Use Positive Behavior Support: Function-Based Interventions For Preschool Children With Challenging Behavior, Lauren E. Pace

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parents who have children with challenging behavior may feel stressed, overwhelmed and at a loss for solutions. Challenging behavior can cause problems with children’s relationships with others and their school success. There are many resources for schools and children with special needs; however, resources for parents for young children (ages 3 to 5) with challenging behavior are limited. This study examined the impact of a 6-week intervention to coach parents to use strategies that encouraged children to develop skills that helped them to express frustration and solve problems in positive ways. Parents were better able to understand what the children …

Evolution Of The Book Cliffs Dryland Escarpment In Central Utah - Establishing Rates And Testing Models Of Escarpment Retreat, Nicholas R. Mccarroll

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the earliest explorations of the Colorado Plateau, geologists have suspected that cliffs are retreating back laterally. Clarence Dutton envisioned “the beds thus dissolving edge wise until after the lapse of millions of centuries their terminal cliffs stand a hundred miles or more back from their original position” when he wrote about the landscape in 1882. While many geologic studies have determined how fast rivers cut down through the Plateau, only a few studies have calculated how quickly cliffs retreat laterally, and geologists have been arguing since the 1940’s what exactly drives cliffs to retreat in the first place. We …

Relationship Maintenance Behaviors And Marital Stability In Remarriage: The Examination Of Stepfamily Constellations And Associated Challenges, Ron C. Bean

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research on stepfamily life in the 21^st century reveals unexplored variables at every turn. This is important because around half of American adults report close step-relationships and the challenges and demographic and relational differences for different types of stepfamilies remains unexplored. The first of these studies explored data for 879 husbands and wives couples to explore how positivity, negativity, and sexual interest levels differ depending which of the couple, both partners, or neither had previous children. Wives reported higher levels of marital instability and positivity than husbands. Marital instability was linked with one’s own and one’s partners’ negativity, and …

The Influence Of Adjacent Weed Populations On Thrips And Iysv In Onion, S. Andrew Swain

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Onion thrips (Thrips tabaci) and Iris Yellow Spot Virus (IYSV) constitute a pest complex of global concern for allium growers. Yield losses due to onion thrips alone can be heavy, and in tandem with IYSV, these losses can be complete.

This study was one phase of a multi-phase research project intent on exploring the potential drivers of thrips and virus infestation in onion. Preliminary observations in participating growers’ fields in northern Utah pointed towards a potential link between weedy field borders and thrips/IYSV infestation in onion. Field work was carried out at the Kaysville experiment station examining the …

The Farm As Place In A Changing Climate: Capturing Women Farmers' Experiences In Idaho, United States And Victoria, Australia, Tagen Towsley Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In Australia and the US, women play a vital role in the agricultural sector. However, historically farmwomen’s contributions to agriculture as well as their individual knowledge and social resilience to stressors like climate and climate change have been unrecognized and rendered invisible. Drawing on interdisciplinary scholarship from geography and the humanities, this dissertation explores the farm as place in a changing climate, drawing on women farmers’ experiences, under three distinct themes: identity, place, and photography. The dissertation research includes three distinct parts. First, incorporating non-fiction writing and photography, I explore my agricultural and religious heritage, as well as familial connections …

Revolution In Autonomous Orbital Navigation (Raon), Rachit Bhatia

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spacecraft navigation is a critical component of any space mission. Space navigation uses on-board sensors and other techniques to determine the spacecraft’s current position and velocity, with permissible accuracy. It also provides requisite information to navigate to a desired position, while following the desired trajectory. Developments in technology have resulted in new techniques of space navigation. However, inertial navigation systems have consistently been the bedrock for space navigation.

Recently, the successful space mission GOCE used on-board gravity gradiometer for mapping Earth’s gravitational field. This has motivated the development of new techniques like cold atom accelerometers, to create ultra-sensitive gravity gradiometers, …
