Bridging The Gap: Exploring The Development Of Science Self-Efficacy Among Students With Learning Disabilities, Aria Hadley-Hulet

All Graduate Theses and Dissertations, Fall 2023 to Present

Students with learning disabilities are often overlooked in efforts to broaden participation in STEM. This multi-paper dissertation investigates science self-efficacy among this population through the lenses of the social model of disability and self-efficacy theory. An integrative review reveals consistently lower academic self-efficacy among students with learning disabilities and a lack of research examining their science self-efficacy specifically. Quantitative analysis of national data shows lower science self-efficacy overall, yet no differences among students enrolled in advanced science courses. A mixed-methods study further demonstrates that in inclusive school environments characterized by asset-based teacher beliefs and normalized accommodations, science self-efficacy differences disappear. …

The Effects Of Psychological Stress On Gut Health In Mice Fed Either A Healthy Diet Or The Total Western Diet, David Keenan Thomas Prescott

All Graduate Theses and Dissertations, Fall 2023 to Present

The Total Western Diet (TWD), a rodent diet designed to model the typical American dietary pattern, has been shown to worsen inflammation and colitis severity in mice. Psychological stress has also been associated with increased intestinal inflammation, barrier dysfunction, and alterations to the gut microbiome. The goal of this study was to determine whether combining the TWD with psychological stress would further worsen colitis severity and alter the gut microbiome. To investigate this, mice were fed either a healthy control diet or the TWD and exposed to psychological stress using a social disruption stress model. Colitis was induced using established …

Viability Assessment Of Bovine Embryos: A Public Dataset And Deep Learning Baselines, Erfan Khayyati

All Graduate Theses and Dissertations, Fall 2023 to Present

Improving the success rates of cattle breeding is essential for sustainable agriculture, global food security, and high-quality livestock production. Currently, determining whether a lab-grown bovine embryo is healthy enough for a successful pregnancy requires highly trained experts to manually evaluate days of continuous time-lapse video footage. This process is not only incredibly time-consuming but also highly subjective; human reviewers often suffer from visual fatigue when tracking subtle, microscopic cellular changes over a seven-day period, leading to significant disagreement among even top experts on an embryo’s true potential. Furthermore, assessing bovine embryos is notoriously difficult due to their dark, lipid-dense cellular …

Affective And Cognitive Factors Contributing To Male-Female Differences In Mathematics, Sarah N. Herod

All Graduate Theses and Dissertations, Fall 2023 to Present

Math differences between men and women have been studied for several decades, with original theories suggesting a biological reason for the differences and more new ones suggesting multiple factors, such as self-efficacy, anxiety, and spatial ability, may be responsible for these apparent differences. Additionally, most research into math differences between the sexes involves the use of a composite score, rather than examining the different sub-domains of math separately. The purpose of the current study was to examine the relationship between sex and math performance within the context of an individual's belief and attitudes towards math and spatial information. Seventy-one participants …

The survey was administered to postsecondary CTE employed at public community and technical colleges in Utah and Colorado (N = 37). Participants were randomly assigned to either a treatment condition, in which they viewed a six-minute-long video vignette illustrating HCD in practice, or a control condition without exposure to the …

Nicotine Aerosol Self-Administration And Reward Potentiation: Using A Preclinical Model Of Vaping To Investigate The Stimulus-Enhancing Properties Of Nicotine, Kiernan T. Callister

All Graduate Theses and Dissertations, Fall 2023 to Present

Tobacco use is the leading cause of preventable disease and death in the United States and worldwide. Nicotine, the primary component of tobacco, is responsible for the addiction to tobacco and nicotine products, such as Electronic Nicotine Delivery Systems (ENDS). The widespread consumption of these products is motivated by several complex properties of nicotine, such as its ability to increase the rewarding value of stimuli in the environment. Although reward enhancement has been demonstrated via smoking and other forms of nicotine intake, it is unclear if these effects extend to electronic cigarettes. The present study used an animal model of …

All Graduate Theses and Dissertations, Fall 2023 to Present

Youth remain underserved in nutrition research, policy, and programming despite being an integral part of the food systems. While the nutrition-sensitive agriculture framework has been established, there is limited evidence demonstrating how youth engagement in agriculture can serve as a pathway to improve nutritional outcomes. The study assessed youth agricultural engagement and its association with household dietary diversity, household food insecurity, and nutritional status in southwest Nigeria.

Using a cross-sectional design, data on socio-demographic characteristics, agricultural engagement, dietary diversity, household food insecurity, body mass index, and skin carotenoids were collected from 143 youth aged 15 to 35 from Ekiti, Osun, …

The Role Of Public Spaces In Facilitating Social Interactions On Summer Weekends, Sierra R. Murray

All Graduate Theses and Dissertations, Fall 2023 to Present

Public spaces such as parks, plazas, and pedestrian areas are important places where people meet, relax, and interact with others. While these spaces are intended to bring communities together, their design does not always support social interaction. This study explored how everyday design features influence how people use public spaces and engage with one another. Features such as seating, trees and plants, shade, water elements, and the way spaces are shaped were examined. The goal was to better understand how design choices affect social life in shared outdoor environments. 

The research involved observing how people naturally behaved in different public …

Specifically, the study considered if good quality patient-provider communication is associated with people feeling an overall sense of autonomy, competence, relatedness, and an overall positive experience of their life. It also considered how much symptoms or treatment of health issues impact people’s lives. Data in the study was collected through an online survey with …

The Augmented Matching Law, Matias A. Avellaneda

All Graduate Theses and Dissertations, Fall 2023 to Present

Every living organism, including humans, has a finite amount of time available: 24 hours in a day, 365 days in a year, and a certain number of years in its life. At every moment, such an organism will be engaging in one of a multitude of possible activities, such as eating, sleeping, or reading this dissertation. We use the term choice to denote the way in which the organism distributes its time among all these activities, and some of these choice patterns are more beneficial to the organism than others, showcasing the importance of understanding the mechanisms underlying choice.

All Graduate Theses and Dissertations, Fall 2023 to Present

It is known that celebrities have influence on their audience’s attitudes and behaviors. Within the last few decades, multiple celebrities have created distinctions between their public/stage self and their private self, however, less is known about the ways that they differentiate between the two. This paper looks at celebrity public persona’s and how these persona’s influence their audience. I use Kayleigh Amstutz, otherwise known as Chappell Roan, as my case study. This thesis offers an analysis of how Amstutz talks about Kayleigh differently than Chappell within social media posts, interviews, and commentary from media outlets. I use the concepts of …

Pavlovian Conditioning And Self-Control: From Laboratory To Classroom Application, Saba Mahmoudi

All Graduate Theses and Dissertations, Fall 2023 to Present

Impulsive choice, the preference for a smaller-sooner reward (SSR) over a larger-later reward (LLR), is associated with various challenging behaviors (e.g., gambling and substance-used disorders). Many interventions can reduce impulsive choice but those that produce long-lasting effects typically require long training durations or are difficult to implement in applied settings. This dissertation evaluated a novel Pavlovian training approach designed to promote self-control. In Experiment 1, procedures from Mahmoudi and Madden (2024) were replicated in the laboratory with the addition of a truly random control group. The study also assessed whether presenting the conditioned stimulus (CS) before a choice would increase …

Resilience, Hope, And Posttraumatic Growth Among Yazidi Refugees, Erin Elizabeth Larson

All Graduate Theses and Dissertations, Fall 2023 to Present

Although it has been more than a decade since the Islamic State of Iraq and Syria (ISIS) imposed genocide upon the Yazidi people, an ethnic minority indigenous to Kurdistan, research on the psychological health of this community is lacking. While traumatic experiences and the accumulation of stressors can overwhelm one’s capacity for resilience, making it especially difficult for refugees to adapt and recover from their experiences. Posttraumatic Growth Theory posits that individuals may overcome such challenges and even undergo positive life transformations. Data were collected from Yazidi young adults using an online survey and examined the associations between resilience, hope, …

An Examination Of Lifetime Traumatic Brain Injury And Anti-Inflammatory Medication Use In The Risk For Alzheimer's Disease, Mikaela A. Drewel

All Graduate Theses and Dissertations, Fall 2023 to Present

Alzheimer’s disease (AD) is the leading cause of dementia in individuals aged 65 years and older. There are a number of lifestyle and genetic factors that affect one’s risk for AD including traumatic brain injury (TBI), and genes such as those for Apolipoprotein E (APOE) and brain-derived neurotrophic factor (BDNF). This study examined sex differences in how TBI history influences risk for AD, exploring genetic variants suspected to play a role in TBI recovery. Additionally, in following an inflammatory mechanism in TBI, the study also determined if nonsteroidal anti-inflammatory drug (NSAID) use reduced subsequent risk for AD. The study analyzed …

Does Acceptance Matter? The Moderating Role Of Acceptance Of Pornography Use In Sexual And Relationship Satisfaction, Alexandra L. Gillespie

All Graduate Theses and Dissertations, Fall 2023 to Present

With more or the general population reporting regular pornography use there has been an increase in interest in the consequences of regular use, especially for romantic relationships. Previously completed research has shown that there are likely other explanations for why pornography use is related to both positive and negative outcomes. This study examines how acceptance might change the influence the relationship between frequency of use and relationship and sexual satisfaction for individuals. This relationship may yield greater understanding of why some individuals report benefits and others report negative effects of pornography use. Findings indicated that for men their level of …

Developing A New Uas Method For Estimating Heat Exposure On Western Us Trails, Jared Young

All Graduate Theses and Dissertations, Fall 2023 to Present

Heat exposure and the risks to human health that stem from it have been studied extensively in the context of urban and occupational settings. Less studied however, is the effect of heat exposure in a recreational setting such as on hiking trails. What makes this fact more surprising is that recreation, especially in the Western US, is extremely popular, with national parks such as Zion and Arches bringing in hundreds of thousands of visitors every year. With millions of recreationists exposed to the hazard of heat every year, it is critical that recreationists are made aware of the dangers they …

The Role Of Autonomy, Competence, And Relatedness In The Relationship Between Ai Use, Resilience, And Motivation Among Engineering Students, Daniel Kane

All Graduate Theses and Dissertations, Fall 2023 to Present

The purpose of this study was to determine how the widespread use of Artificial Intelligence (AI) influences engineering students’ motivation and resilience. Specifically, the role of autonomy, competence, and relatedness as defined in Self-Determination Theory (SDT) was assessed to determine how these basic psychological needs interact with students’ AI use and motivation or resilience. The following research questions guided the study: (1) To what extent do the three basic psychological needs defined in SDT (autonomy, competence, and relatedness) mediate the relationship between the frequency of AI use and students’ levels of motivation (on the self-determination continuum) or resilience in an …

Reciprocal Teaching With Emergent Bilingual Students: Promoting Academic Reading Strategies And Fostering Hope, Lorissa K. Nelson

All Graduate Theses and Dissertations, Fall 2023 to Present

Many students struggle with reading comprehension, and research shows that low literacy skills in a student’s first language can unfortunately lead to lower rates of university program completion, regardless of the language of instruction. When students feel empowered and confident in their ability to achieve their academic goals, they are much more likely to take ownership of their learning. In fact, students who actively demonstrate hopeful thinking and behaviors are consistently more successful in their academic journeys.

My research explores how we can better support these high school students— specifically concurrent enrollment (CE) students—by examining the impact of Reciprocal Teaching. …

A Comparison Of The Effectiveness Of Teacher-Led And Student-Supported Variations Of The Good Behavior Game, Patrick Wells

All Graduate Theses and Dissertations, Fall 2023 to Present

This project examined the effectiveness of two variations of the Good Behavior Game (GBG) intervention: the traditional teacher-led and a student-supported variation. The traditional intervention has been shown to be an effective intervention for reducing disruptive classroom behaviors. Despite its effectiveness, proper implementation does require additional effort from the teacher—effort that may better be directed toward improving instruction. A student-supported variation of the intervention has the potential to reduce the effort required of teachers who wish to implement the intervention in their classroom. We utilized a nonconcurrent, multiple baseline design with alternating treatment to compare the effectiveness of both versions …

Effects Of Single-Session Interventions On Youth Internalizing Problems, Thomas K. Franzmann

All Graduate Theses and Dissertations, Fall 2023 to Present

Anxiety and depression are among the most common mental health concerns young people face, and they often interfere with school, friendships, family life, and long-term well-being. Even though effective therapies exist, only about half of youth who need care ever receive it, and among those who do start treatment, the most common total number of sessions a young person attends is one. This gap between what young people need and what they actually receive raises a practical question for the field: can a single, well-designed meeting with a provider produce meaningful change for some youth and families, and what should …

Visibility Assessment In Urban Areas: Exploring Measures And Approaches For Viewing Green Space, Doo Hong Lee

All Graduate Theses and Dissertations, Fall 2023 to Present

Urban greenery is often used to understand the quality of living conditions in cities. However, measuring greenery is not always simple. Some methods show how much vegetation exists from above, while others try to show what people actually see while walking or moving through streets. These are different ways of understanding green space. This dissertation focuses on visible greenness, or the greenery that people can see from eye level in everyday urban environments.

This research addresses a practical problem. Many existing methods for measuring visible greenness require large image datasets, advanced computing, or commercial street-view images. These requirements can make …

Cultural Humility In Motion: A Graduate Student Hybrid Immersion In Self- And Other Awareness Through Dance, Emily Jeanne Slater

All Graduate Theses and Dissertations, Fall 2023 to Present

Universities bring together people from many different backgrounds, identities, and experiences. Yet university spaces often focus on mind-centered and discussion-based learning and overlook how the body plays a role in education. When education ignores the bodily experience of learning, students lose opportunities to reflect, connect, and make meaningful change in their lives and communities. To address this gap, this dissertation designed and implemented a learning experience for graduate students that creates space from them to examine their own assumptions, engage across differences, and share in inclusive practices. The learning experience draws on and advances cultural humility theory, which understands self-awareness, …

Evolving Roles: School Counselors Addressing Mental Health In Pk-12 Education, Evin Daines

All Graduate Theses and Dissertations, Fall 2023 to Present

A significant number of children and youth are currently experiencing poor mental health. School counselors work with all students and are in a position to provide support to students experiencing mental health challenges. School counselors can also identify what may hinder children and youth from accessing mental health resources in their communities. This study explores how many school counselors engage in mental health counseling, how school counselors view their roles in addressing student mental health, and what barriers they perceive as keeping children and youth from accessing mental health and behavior services.
