Comparing Lower-Limb Muscle Activity During Gait Performed In Water Versus On Land, Christopher Long

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

The purpose of this study was to compare lower-limb muscle activation during gait, performed in water versus on land, in order to provide preliminary evidence for the benefit of aquatic treadmill walking in treating individuals with foot drop. Foot drop is a debilitating symptom of several neurological disorders characterized by the inability to dorsiflex the foot while walking. Generally, it is due to weakness in the ankle dorsiflexor muscles and/or increased tone in the plantar flexor muscles. Previous research has found that exercise interventions that demand greater than normal activation of the tibialis anterior (TA) (i.e., the primary ankle dorsiflexor) …

An Integrated Experimental And Modeling Approach To Design Rotating Algae Biofilm Reactors (Rabrs) Via Optimizing Algae Biofilm Productivity, Nutrient Recovery, And Energy Efficiency, Gerald Benjamin Jones

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

Microalgae biofilms have been demonstrated to recover nutrients from wastewater and serve as biomass feedstock for bioproducts. However, there is a need to develop a platform to quantitatively describe microalgae biofilm production, which can provide guidance and insights for improving biomass areal productivity and nutrient uptake efficiency. This paper proposes a unified experimental and theoretical framework to investigate algae biofilm growth on a rotating algae biofilm reactor (RABR). The experimental laboratory setups are used to conduct controlled experiments on testing environmental and operational factors for RABRs. We propose a differential-integral equation-based mathematical model for microalgae biofilm cultivation guided by laboratory …

Guiding The Future Of The Cache County Fairgrounds, Logan Hall

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

The County fairgrounds have been a fixture in Cache Valley, Utah for over 100 years. They provide a valuable resource to the community. Effective planning can ensure the appropriate use of this public asset and prevent underutilization. Modern design guidelines have been developed for other fairgrounds in the Intermountain West, but not the Cache County fairgrounds. This research is focused on developing a contemporary visioning plan to guide the growth and future of the County fairgrounds, create design guidelines for future development, and maximize the fairground’s economic potential. The methodology used to develop this plan involved an extensive review of …

Immigrants’ Attitude Toward Immigration, Aflatun Kaeser

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

This study analyzed the relationship between immigration attitudes and demographic and socioeconomic factors. It examined the difference in attitudes toward immigration in the immigrant population using General Social Survey 2021 data. The analysis with an ordered probit model reveals significant relationships between immigration attitude with several socioeconomic and demographic factors and how that differ between natives and immigrants. As age increases, support for limiting immigration increases, but this is not true for immigrants. With the increase of years of education, support for limiting immigration decreases; however, in the immigrant population, support for limiting immigration increases as the education level increases. …

The Intermountain West Lgbtq+ Oral History Project: The Folklorization Of Queer Theory, John Priegnitz

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

Following the passing of a friend who witnessed firsthand the transformation of Salt Lake City’s Queer community from the 1950s to 2020, I created the Intermountain West LGBTQ+ Oral History Project to document the queer experience within the Intermountain West. Since beginning the project in 2020, I have documented several diverse stories that intersect class, race, sexuality, gender, faith, and politics. By documenting the queer experience, a marginalized community will have their voices heard and preserved for the enlightenment of future generations. This presentation provides an overview of my project and its preliminary findings.

Historic Downtown Streetscape Plan Price City, Utah, Patricia Beckert

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

The idea of a small-town Main Street has profound meaning within the American culture that has prevailed for the past two centuries. Historically, Main Street serves as the beating heart of a community, a place where economic, social, cultural, and civic activities are centered (Francaviglia, 1996; Main Street America, n.d.). Since the beginning of the 19th century, many factors have led to the decline of Main Streets, and despite a variety of efforts from different stakeholders, that decline has only intensified in recent decades (Isenberg, 2008; Orvell, 2014 Howard, 2015). In 1980, after a three-year project conducted by the National …

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 …

Assessing Stream Ecosystem Structure And Function In An Urban Canal And Logan River In Logan, Utah, Ellie Smith-Eskridge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humans have constructed canals to support agriculture, to mitigate flooding, and to discharge stormwater, especially in the Intermountain West. These canals are common in Cache Valley, where they receive flows from the Logan River during summer months. However, the ecological structure (e.g., water quality, freshwater invertebrates) and function (e.g., leaf decomposition) of these canals remains largely unknown. Studying ecosystem structure and function of these urban waterways is important because it can inform us of the health of these waterways.

My research had three objectives. First, I compared water chemistry, invertebrate assemblages, and leaf decomposition in an urban canal and the …

An Evaluation Of U.S. Horseback Riding Instruction Certifications: Availability, Acquisition, Barriers, And Industry Need, Makenna L. Osborne

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this mixed-methods study is to analyze the U.S. equine industry’s availability of riding instruction certification options, describe the relationship between professional certification and the self-efficacy of horseback riding instructors in the U.S., and explore the expectations that consumers have of instructors and instructor selection criteria. Two surveys were developed and sent out to instructors and consumers aligned with the research objectives designed to collect information on instructors’ self- perception of self-efficacy after certifying their perceived barriers to receiving certification, and consumers’ selection criteria for instructors. The average certified instructor was extremely satisfied with their decision to pursue …

Establishment Of A Transgenic Human Angiotensin Converting Enzyme-2 Hamster Infection Model For The Evaluation Of Therapeutics Against Severe Acute Respiratory Syndrome Coronavirus 2, Scott A. Gibson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The virus SARS-CoV-2 emerged in late 2019 and has gone on to spread throughout the global population. The virus is still the cause of a healthcare crisis two years after being identified. Viral infection in humans leads to the development of the disease COVID-19. A complex disease that can result in a wide variety of outcomes for infected individuals. In the majority of individuals, COVID-19 will manifest as either an asymptomatic disease state or a mild to moderate disease state that is resolved in approximately one week. In some infected patients COVID-19 will manifest with the rapid onset of severe …

Identifying Common Resources Teachers Use To Address Problematic And Challenging Student Behvior, Joseph Clint Nicholes

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 …

Fractally Sampling Diversity-Environment Relationships To Understand Plant Assemblage Health Across Spatial Scales, Elizabeth G. Simpson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humans influence the health of ecosystems and rely on healthy ecosystems to support their livelihoods and well-being. By looking at how the parts of ecosystems interact we can understand and improve ecosystem health. Ecosystem interactions change across spatial scales or different size patches of area. For example, individual organisms interact with each other at small spatial scales, while at large spatial scales, communities of organisms interact with weather conditions. However, many research studies do not look at how ecosystem interactions change across spatial scales. To address this gap in ecological research, I use a fractal sampling design which samples at …

County Characteristics And Opioid Mortality Rates In The United States, Baksun Sung

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Opioid overdose deaths are not equally distributed across the United States. While some areas have a less severe problem with opioid abuse, others face serious challenges, which are affected by various social factors. To address that question, in Chapter 1, I investigate how opioid mortality trends differ according to opioid types, race, and region to identify susceptible populations and areas. In Chapter 1, I contend that synthetic opioid is a main trigger for the current opioid epidemic and that the epidemic is concentrated among blacks and in the Eastern United States. Next, the following studies examine how varying social vulnerabilities …

Critical Democratic Education: A Case Study On Controversy Deliberation And Its Effects Among Pre-Service Elementary Teachers, Shouqing Si

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The state of democracy facing expanding political division and pervasive racial and social inequalities. Discussing and deliberating controversial social and political issues functions help foster students' civic contribution. I conducted a qualitative case study and recruited 14 participants, with whom I conducted interviews, self-reflection, observation, and autoethnography. I targeted the primary research question: How do pre-service elementary teachers experience and get influenced by discussing social and public issues? I broke it down to six operational questions:

1. What issues are considered controversial by pre-service teachers in their future social studies classrooms?
2. What challenges do pre-service teachers perceive in controversial issues teaching? …

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 …

An Exploration Of Issues Facing Vertiport Integration In The Wasatch Front, Katelynn Hall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Uncrewed Aerial Systems (UAS) are expected to fill our skies to provide services such as package delivery, supporting emergency services, and even as a new mode of transit. While the private sector has been developing UAS for many years, the planning realm has not considered this new technology’s potential impacts on our communities in any depth. A primary aspect of UAS integration is the development of vertiports, which facilitate ground-based interaction with UAS. These centers, unlike traditional aerial infrastructure, must be dispersed throughout communities to support UAS integration. This thesis aims to involve planning professions in UAS integration by identifying …

Thermal Tolerance, Physiology, And Microhabitat Use Of Eleutherodactylus Coqui Across An Elevational Gradient In Hawai‘I, Jack Marchetti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The coqui frog (Eleutherodactylus coqui) is an invasive species in Hawai‘i, and has spread across much of the island. While elevational temperature differences are thought to restrict the coqui’s spread, it is unclear if they have resulted in changes to the coqui’s physiology and microhabitat use as it has expanded into higher elevations.

We first sought to determine if the coqui’s substrate use and baseline physiology differs between elevations. We found that frogs at high elevation were found closer to the forest floor and used different substrates than frogs from low and mid-elevations. This change in microhabitat use …

Exploring The Process Of Mindful Breathing With Stressed Mothers, Caleb D. Farley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mindfulness exists in many parenting and family interventions and are intended to decrease stress, improve familial relationships, and indirectly improve child wellness, and these mindfulness-based interventions (MBI) are relatively effective at doing so. However, critical issues remain related to designing effective and useful interventions for school-based and other community practitioners. Specifically, research has not demonstrated clear relationships between parent mindfulness practice increasing generalized mindfulness behaviors (i.e., awareness and acceptance), experiencing subsequent parental stress reduction, and reporting decreased behavior problems in children. The current study examined these relationships between practicing mindfulness and experiencing changes in parents’ mindfulness process, wellbeing, and perceptions …

The Barriers To Movement: The Effects Of Anthropogenic Linear Features On The Space-Use Behaviors Of Mule Deer And Pronghorn In Utah, Ronan B. Hart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Human development of structures like roads, fences, and other linear features can make it difficult for animals to move around their environment, affecting their ability to find food and avoid danger. Animal movement and the way they use space comes about from their responses to their surroundings and their choices to balance risk and reward. Because of this, we can understand how roads and fences affect wildlife by studying the way they move around their habitats. In this thesis, I focused on two large herbivores, mule deer and pronghorn, and studied how they use the space within Utah, United States …

The Relation Between Racial Attitudes And Facets Of Impulsivity, Diana M. Perez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Racism is an ongoing issue in U.S. society. The present study examined the relation between racial attitudes and two types of impulsivity (i.e., behavioral inhibition and delay discounting). Prior research has not touched upon the relationship between impulsivity and racial bias; nonetheless, the factors that influence the ability to interfere with automatic thinking and bad decision making may be a way to address racial bias. One hundred eighty-seven White adult participants were recruited from Amazon Mechanical Turk (MTurk), an online survey taking website. The value participants place on future rewards (i.e., delay discounting) and the ability to stop their behavior …

Regeneration Of Quaking Aspen And Understory Vegetation Change After Fire Risk Reduction Treatment, Allison M. Trudgeon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Quaking aspen (Populus tremuloides Michx.) is a keystone species that, when coexisting with conifers (i.e., seral aspen), often undergoes stand-replacing disturbances to sustain long term vigor. Historically, mixed-to-high severity fire reduced fuels and regenerated aspen, but such disturbances have become less common in recent decades. This has often led to high fuel loading, and many seral aspen stands are at now risk of an unpredictable, high-severity fire, posing a threat to development in the wildland-urban-interface. The lack of a commercial market for aspen, and the risk of conducting prescribed fire, means there are few alternate management options. This has …

Evaluating Methods For Pathogen Spillover Detection And Forecasting In Desert Bighorn Sheep (Ovis Canadensis Nelsoni), Grete E. Wilson-Henjum

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Managers mitigate the effects of disease on wildlife populations by detecting outbreaks and predicting disease transmission. Bighorn sheep (Ovis canadensis) populations face threat from the introduced pathogen Mycoplasma ovipneumoniae (M. ovipneumoniae). In the eastern Mojave Desert, managers detect pathogen outbreaks in desert bighorn (O. c. nelsoni) through aerial population surveys, which produce irregular and coarse population information. Furthermore, managers model the risk of M. ovipneumoniae transmission amongst desert bighorn populations, however these models assume that desert bighorn space use is unchanging across years. Here, I evaluate methods used by managers to detect disease outbreaks …

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., …

From Mountain Streams To Urban Rivers: An Assessment Of Microplastic Sources And Characteristics, Macy Gustavus

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plastic products are produced and discarded at an alarming rate. Bottles, bags, toys, and clothing break down into tiny plastic pieces called microplastics, ranging in size from an eraser on the top of a pencil to smaller in size than a red blood cell. Microplastics are becoming so common in the environment that they travel in the atmosphere, rivers, and ocean currents in ways that are similar to other types of Earth Systems Cycles (i.e., the water cycle). In this study, we explored microplastic sources and sinks in a freshwater river system and how seasonal changes in discharge affect how …

Board Certified Behavior Analysts In Public Schools: Challenges And Opportunities, Danielle Lyons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Board Certified Behavior Analysts (BCBAs) can play an important role in schools. The purpose of this study was to survey BCBAs who self-identify as working in public schools in effort to learn more about their experiences working in this setting. This paper is meant to spark further discussion and research on how BCBAs can be more effective in schools through training and supervision, collaborating with school administrators on systems-level concerns, resolving ethical concerns, and clarifying roles and responsibilities in public schools.

A Questionnaire Survey Of Student Engagement Among First-Generation College Students In Engineering, Abigail Lehto

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

First-generation college (FGC) students are defined as students whose parents do not have a bachelor's or graduate degree. FGC students tend to face more overall challenges in the college environment than their continuing-generation counterparts. Often, FGC students have lower grade-point-averages (GPAs) and are less likely to graduate than their peers. In majors like engineering, the struggles that first-generation college students face can be further magnified. This quantitative study examines the activities FGC students in engineering engage in based on the National Survey of Student Engagement (NSSE). Questions from the NSSE cover different educational activities and are categorized into ten educational …

Who Is Accessing Ipse Programs? Examining The Demographics Of Students Enrolled In Inclusive Post-Secondary Education, Madison Heider

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This initial survey study was designed to examine the demographics of students attending inclusive post-secondary (IPSE) programs for students with intellectual and developmental disabilities (IDD). IPSE programs are designed to deliver a similar, if not identical, collegiate experience to students with IDD as their peers without disabilities. Previous research has investigated IPSE programs and their impact, but there is limited information regarding student makeup. The researchers looked to identify the diversity of students beyond their disability categories; research questions surrounded student diversity, barriers to accessing IPSE programs, and what, if anything, programs do to increase diversity within their programs. The …

Status And Enhancement Of Trissolcus Japonicus (Ashmead) (Hymenoptera: Scelionidae) For Biological Control Of Halyomorpha Halys (Stål) (Hemiptera: Pentatomidae) In Northern Utah, Kate V. Richardson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The invasive brown marmorated stink bug (BMSB) is a major insect pest that invades human structures causing nuisance issues and attacks numerous fruit and vegetable crops in Northern America. As this pest threatens $23 billion worth of specialty and agricultural crops in the U.S. and is difficult to manage due to insecticide resistance, control practices such as the use of biological control through egg parasitoid wasps are critical. In its native range of Asia, BMSB populations are controlled primarily by members of the Trissolcus genus such as the samurai wasp, but U.S. native wasps have demonstrated low success of BMSB …

Deep Learning With Attention Mechanisms In Breast Ultrasound Image Segmentation And Classification, Meng Xu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Breast cancer is a great threat to women’s health. Breast ultrasound (BUS) imaging is commonly used in the early detection of breast cancer as a portable, valuable, and widely available diagnosis tool. Automated BUS image analysis can assist radiologists in making accurate and fast decisions. Generally, automated BUS image analysis includes BUS image segmentation and classification. BUS image segmentation automatically extracts tumor regions from a BUS image. BUS image classification automatically classifies breast tumors into benign or malignant categories. Multi-task learning accomplishes segmentation and classification simultaneously, which makes it more appealing and practical than an either individual task. Deep neural …
