Increasing Knowledge And Detection Of Racial And Ethnic Microaggressions In White College Students, Christina A. Patterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Scholars have strongly suggested that to combat microaggressions and their impact on persons of color, there needs to be an increased awareness and ability to detect microaggressions when they occur. There is limited research on how to practically address these concerns. This study examined the efficacy of a multimedia intervention aimed at increasing White individuals’ ability to accurately detect microaggressions. The high-exposure intervention was compared against two other conditions, low-exposure and control, at pre-, post-, and 1-week follow-up from intervention.

Undergraduate university students were recruited from two predominantly white universities (PWU). Participants watched a series of videos to determine if …

Impact Of Climate Variability On The Frequency And Severity Of Ecological Disturbances In Great Basin Bristlecone Pine Sky Island Ecosystems, Curtis A. Gray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many high elevation conifer species, including high elevation five needle pines, are declining throughout western North America. Warming temperatures, mountain pine beetle, white pine blister rust and alteration of naturally occurring fire regimes represent an interactive set of circumstances leading to greater risk. The loss of these treeline pines can detrimentally impact biodiversity and valuable ecosystem services including wildlife habitat, watershed and soil protection, aesthetics and recreation. Great Basin bristlecone pine ecosystems are naturally highly fragmented because of their elevational requirements. However, they may become even more fragmented due to combined impacts of warming temperature, insects and diseases listed above. …

The bridge is located in Salt Lake City at about 2100 South and Interstate 15. This bridge has two kinds of instruments on it: accelerometers and thermocouples. The accelerometers measure the vibrations of the bridge. The accelerometers have been recording data on the bridge since 2001. The thermocouples, which measure temperature, were added as part of this thesis in April 2016.

In light of recent research, damage may be detected from measuring the change in …

Transportation Related Challenges For Persons With Disabilities, Graydon Bascom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Gaining access to transportation is essential for obtaining employment, education, healthcare, and social interaction. Individuals who face difficulties in gaining this access are considered ‘transportation disadvantaged’ and include individuals of lower socioeconomic status, aging individuals, and persons with disabilities. In our autodependent society, individuals with disabilities face even fewer opportunities to interact within their communities. In order to better understand how individuals with disabilities are limited by their access to transportation, two studies were conducted.

The first study specifically seeks to examine how individuals with disabilities gain access to transportation and the interpersonal relationships that affect opportunities for social participation …

Participation In Dual Language Immersion Programs: Using Theory Of Planned Behavior To Predict Enrollment, Andrea Call

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many theories have been developed to help explain and predict human behavior. Ajzen’s Theory of Planned Behavior (TPB) holds that behavior is based on behavioral intention, as well as attitudes, subjective (or social) norms, and perceived behavioral control. According to the TPB mode, perceived behavioral control moderates (or influences) the effect of behavioral intentions on behavior. Previous research has focused on the application of TPB to health behaviors, although some research has been done in educational situations. In addition, dual language immersion (DLI) programs are increasing in popularity, particularly in Utah. The Utah model begins in first grade, and follows …

Propagating Perfection: Eugenic Sterilization At The Utah State Training School, 1935 - 1974, Jennifer Rust

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Compulsory sterilization as a tool of eugenics occurred in the United States from before the U.S. Supreme Court upheld its’ constitutionality in 1927 until the early 1970s. Initial justification for removing a person’s ability to procreate was rooted in hereditarian assertions that disability was transmitted from parent to offspring, and incorporated an economic argument that individuals with disabilities placed a financial burden on the state for care. Due to scientific deconstruction of the hereditarian argument, rationalization for sterilization evolved into an anxiety over the perceived inability of the disabled to parent. The state of Utah sterilized 738 individuals with intellectual …

Attitudes And Experiences Of Close Interethnic Friendships Among Native Emerging Adults: A Mixed-Methods Investigation, Merrill L. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Members of small minority groups like Natives, along with other minority groups that are rapidly growing in population are increasingly receiving research focus. With 1 in 3 U.S. residents identifying with racial or ethnic minority groups, close interethnic relationships are likely to increase as well. It will be important to understand processes of close friendship development between racially-different friends, along with the factors that help establish and maintain these close interethnic friendships. This information will be especially important for members of small minority groups, such as Natives.

We investigated Native friendship development and factors of close friendship with non-Native emerging …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to better understand how activities may impact quality of life on dementia care units. Researchers observed dementia care units, and looked into how different activity types impacted emotional affect in the person with dementia, and how they elicited different levels of positive staff interaction. Results indicated that there were significantly higher levels of positive affect from participants on certain activity types, compared to no activity. Activities that had high levels of staff to client interactions had more positive affective outcomes. Researchers concluded that quality activities should consider the environment, staff ratio, staff communication and interaction, engagement …

Comparing The Effect Of Carbon Sources, Lactate And Whey, On Biological Reductive Dechlorination Of Tce In Laboratory Flow Through Columns, Sarah M. Kissell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Trichloroethylene (TCE) is a chlorinated solvent most commonly used as an industrial degreaser for cleaning mechanical equipment. Historic improper management and disposal of TCE has resulted in contaminated soil and groundwater across the United States, including Hill Air Force Base in Utah. The abundance of TCE in the environment presents a public health risk because it is categorized as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC).

The purpose of this study was to improve the bioremediation techniques of biostimulation and bioaugmentation. A continuous flow-through column study was performed where columns packed with aquifer material …

Diversity-Related Experiences Among College Students In The Promotion Of Social Justice Orientation, Multicultural Openness, And Community Involvement, Alexandra K. Reveles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Institutions of higher education serve students in more ways than simply fostering academic growth. University and college campuses are often the introduction people have to the societal, interpersonal, and career/field specific expectations they will be guided by after completing their degree. One way for universities to do this is through the cultivation of critical consciousness by way of encouraging engagement in diversity-related activities. This study examined associations between engagement in diversity-related activities and reported levels of critical consciousness, along with differences between students of color and White students in patterns of association.

Diversity-related experiences, including extracurricular diversity activities, positive cross-racial …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Employees in the field of human services can influence the health and rate of progress of the clients they serve. A human service supervisor’s responsibilities include identifying why an employee may be performing poorly and provide an effective intervention to ensure improved performance. The Performance Diagnostic Checklist for Human Services (PDC-HS) has been used in treatment clinics to identify the variables that can contribute to poor employee performance, and subsequently recommend an intervention to improve performance.

The special education classroom is a human service setting in which special education teachers supervise paraeducator’s skills and performance. A paraeducator’s role includes providing …

Evaluating The Effectiveness Of Utah Farm Field Days, Paige Wray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah farm field day events seek to increase agricultural literacy among elementary students. Although these events are occurring statewide, no formal evaluation has been conducted to determine student increases in agricultural literacy related to these events. The purpose of this study was to evaluate two such events to see what students knew about agriculture before they attended the farm field day, what they wanted to learn about concerning agriculture, and what they learned after attending the event. Results showed that these children were below average for expected grade level understandings or agricultural awareness before the event. However, after the event, …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Legumes that contain condensed tannins (CT) may have lower protein degradability than alfalfa. The present study investigated the effects of feeding birdsfoot trefoil (Lotus corniculatus L.) hay on lactation performance and N utilization. Eight multiparous Holstein cows in mid lactation (150 ± 22.3 d-in-milk) were randomly assigned to 1 of 2 rations [alfalfa hay-based TMR (AHT) or birdsfoot trefoil hay-based TMR (BFTT)] in a crossover design with 2 experimental periods. Each experimental period lasted 16 d (14 d of adaptation and 2 d of total collection), and the 2 experimental periods were separated by a 7-d washout period. In the …

Pharmaceuticals And Personal Care Products In An Effluent-Dominated Stream: Seasonal Variability And Downstream Fate, Bradley R. Buswell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pharmaceuticals and personal care products (PPCPs) consist of a large group of compounds including medicines, lotions, soaps, shampoos, and even flame retardants and insect repellants. After use, PPCPs often enter waste streams that are directed to municipal wastewater treatment plants (WWTPs). Due to inefficient removals in conventional wastewater treatment processes, WWTP discharges into streams and rivers are a major source of PPCPs to the environment.

The East Canyon Water Reclamation Facility (ECWRF) is a WWTP in Park City, Utah. After treatment, the ECWRF effluent is discharged into a small constructed wetland area before it enters East Canyon Creek. Due to …

Determining Natural Frequencies Using Embedded And Placed Sensors Under Ambient And Shaker Excitation, Tyson Scott Alder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Structural Health Monitoring (SHM) includes methods of detecting damage to structures over their lifespan. Using the structure’s dynamic characteristics, internal damage and other changes can be detected and defined. Dynamic characteristics are affected by many operational parameters, particularly temperature effects. By defining the operational condition of a healthy structure, changes from the baseline condition can be detected and defined as damage. Defining the operational characteristics of the structure are imperative to detecting damage.

This study focused on defining the baseline dynamic properties of the recently constructed Nibley Bridge using embedded sensors. Multiple tests were performed to provide a range of …

Public Opinion On Renewable Energy: The Nexus Of Climate, Politics, And Economy, Shawn K. Olson-Hazboun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation research examines the factors underlying public opinion toward renewable energy in the United States. U.S. citizens in general support the continued development of renewable energy, yet opposition has been widely observed toward a variety of renewable energy facilities at the local level. Previous research on public responses to renewable energy has focused on one or a small number of communities experiencing renewable energy development. In this research I examine public views more broadly, in communities with and without renewable energy development, and also using nationally representative opinion data. I ask the following questions:

What local experiences influence how …

Alternative Treatment Technologies For Low-Cost Industrial And Municipal Wastewater Management, Alan J. Hodges

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Roughly the same volume of water that rushes over the Niagara Falls is produced as wastewater in North America. This wastewater is treated through a variety of means to ensure that it can be safely returned to the natural ecosystem. This thesis examines two novel means for this treatment, one biological and one physical-chemical in nature, namely, Rotating Algae Biofilm Reactor treatment and expanded shale augmented coagulation-flocculation.

Rotating algae biofilm reactors (RABRs) support biofilm algae growth, and in turn, the algae take up harmful contaminants from the wastewater. This system was tested in wastewater from petroleum refining operations. The efficacy …

Algae-Based Biofilm Productivity And Treatment Of Dairy Wastewater: Effects Of Temperature And Organic Carbon Concentration, Zachary T. Fica

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production of dairy and associated products is a source of millions of gallons of wastewater every year. Water used in cleaning feeding stalls as well as the liquid component of the animal waste are two of the major volumetric components of this wastewater. This water is nutrient rich, often limiting the viability as a land applied fertilizer. However, these same nutrients could be used as an inexpensive feedstock for the cultivation of algae, which can then be used to produce downstream products including animal feed and aquaculture.

As part of this study, algal biomass was cultivated on dairy wastewater from …

Effectiveness Of Acceptance And Commitment Therapy As A Treatment For Posttraumatic Stress Disorder And Moral Injury, Ellen J. Bluett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Posttraumatic stress disorder (PTSD) is a common condition among military personal and veterans. Despite strong empirical support for first line treatments for PTSD, many veterans do not complete or respond to treatment. Research suggests that experiential avoidance is a contributing factor to both treatment dropout and minimal treatment gains. Acceptance and commitment therapy (ACT) is an empirically supported cognitive behavioral intervention that aims to decrease experiential avoidance while increasing psychological flexibility. Research has shown ACT to be a promising intervention for the treatment of PTSD; however, its effectiveness in veterans with PTSD is limited.

In conjunction with Utah State University …

International Policy Diffusion And Religious Freedom, 1990-2008, Allison R. Hale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Why do governments restrict religious freedom? As more and more governments have adopted restrictive policies over the past thirty years, scholars have traditionally examined internal domestic factors—such as the role of democratic governance, economic growth, or internal competition—that may influence government choices. I build on this literature by extending the discussion to external factors, arguing that some policies may also spread from one government to another. This process, identified by scholars as the idea of policy diffusion, may occur in several ways.

While previous research has focused on the spread of policies that are generally considered positive (i.e. the spread …

Establishing A Kinetic Assessment Of Reactive Strength, Talin Louder

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three neuromuscular characteristics are identified in Sheppard and Young’s model of agility: concentric strength and power, bilateral symmetry, and reactive strength. Measures of reactive strength attempt to model the neuromuscular regulation of tissue stress and strain. The Coefficient of Reactivity (CoR) is the first known assessment of neuromuscular reactivity. The CoR was developed as an assessment of neuromuscular performance in drop jumping. The construct validity of the CoR was placed in question when Warren Young proposed the Reactive Strength Index (RSI). The RSI improved the theoretical validity of reactive strength assessment since it included a component measure (ground contact time) …

Do Data Structures Matter? A Simulation Study For Testing The Validity Of Age-Period-Cohort Models, Sun Young Jeon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Age, period, and cohort are three temporal dimensions that can make unique contributions to social and epidemiological changes that occur in populations over time. However, while the theoretical underpinnings for each temporal dimension are well established, the statistical techniques to assess the distinctive contributions of age, period and cohort are controversial. Unless questionable assumptions are imposed on the data, traditional linear regression models are incapable of estimating the independent contribution of each temporal dimension due to the linear dependence between age, period and cohort (A=P-C). Two recently developed methods, Hierarchical Age-Period-Cohort (HAPC) and Intrinsic Estimator (IE) models, enable researchers to …

Recreation Community Branding: A Comparative Analysis Within Utah’S Wasatch Front, Lynda D. D. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study demonstrates the role recreational amenities play in contributing to the brand identity and sense of place in Utah master planned communities (MPCs). These MPCs are designed to enable residents to live, work, and play within close proximity within a styled built environment. While the built environment is often branded with a particular identity, these identities resonates with other attributes of the community, including recreation amenities. The study focused on MPCs along the Wasatch Front in Utah, since Utah’s population, along the Wasatch Front, is expected to double by 2050 (Envision Utah, n.d.). Many of the developments being built …
