The purpose of this mixed-methods study was to investigate the relationship between teachers’ conceptions of mathematics and their use of intelligent tutoring systems for mathematics instruction. Intelligent tutoring systems are adaptive computer programs which administer mathematics instruction to students based on their cognitive state. A conception is a mixture of beliefs and knowledge. The participants in this study were 93 junior high school mathematics teachers from three school districts in the Midwest. Data were gathered using a two-part online survey. The first part of the survey contained questions about their use of intelligent tutoring systems, graphing calculators, Desmos and dynamic …

A Structural Equation Modeling Approach Combining Multitrait-Multimethod Designs With Moderated Mediation Analysis, Kaylee Litson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Researchers who study clinical and developmental psychology are often interested in answering questions such as how interventions work, when treatment begins to improve health outcomes, or for whom treatment has the greatest impact. Answers to these and similar questions impact the general understanding of health and behavior, and can be imperative for effectively implementing intervention and prevention programs. To evaluate such complex relationships among variables, researchers have turned to moderated mediation analysis. Moderated mediation analysis is a statistical tool used to identify the conditional processes among observed or latent variables. However, in developmental and clinical psychology, variables are regularly measured …

Urban Alaskan Moose: An Analysis Of Factors Associated With Moose-Vehicle Collisions, Lucian R. Mcdonald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As human populations continue to grow and encroach into wildlife habitats, instances of human-wildlife conflict are on the rise. Increasing numbers of reported wildlife-vehicle collisions (WVCs) provide tangible evidence of anthropogenic impacts on wildlife as well as increasing threats to human health and safety. Increasing WVCs are of particular concern, especially those involving large-bodied ungulates such as moose (Alces spp.), because of the increased risk of property damage, personal injuries, and human fatalities. Motorists directly involved in a WVC are at risk of injury or mortality, but other motorists are also put at risk due to road obstructions and traffic …

Physiological, Behavioral, And Self-Report Outcomes Of Acceptance And Regulation Approaches To Exposures For Intrusive Thoughts, Brooke M. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cognitive-behavioral therapy that includes exposure, or intentionally and systematically confronting feared situations, is the gold standard psychological treatment for obsessive-compulsive disorder. However, less than half of those who begin this treatment are considered to have recovered from their disorder at the end of treatment, and this number is even smaller in the months following the end of treatment. Leading theories regarding how treatment changes occur focus on reducing fear, and they do not include “voluntary” (i.e., operant) behaviors, such as avoidance, that are key features of the disorder. Acceptance-based approaches to exposure do not focus on fear reduction, but directly …

Developmental Trajectories Of Aggression From Toddlerhood To Early Adolescence In Boys And Girls: Exploring Early Predictors And Later Outcomes, Sujung Park

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Early behavior problems, such as childhood aggression, emerge in the second year of life and decrease prior to school entry for typically developing children. However, some children show frequent and persistent aggression and may be at risk for subsequent difficulties that lead to poor school and life outcomes. The current study aimed to identify aggression patterns in children from toddlerhood to early adolescence for boys and girls together and separately. This study also explored early influences on aggressive behaviors at age two, such as mothers’ parenting behaviors, cumulative family risk, and early child characteristics. A range of difficulties in early …

Resurgence Of Cocaine-Seeking In Rats Following Long Access And Punishment, Rusty W. Nall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Strategies that provide access to alternative non-drug rewards are among the most effective at reducing substance use in individuals with substance use disorders, but relapse often occurs when alternative rewards are removed. Relapse induced by the loss of alternative rewards is called resurgence, and represents a challenge to otherwise effective strategies for reducing drug use. An animal model has been useful for studying resurgence, but the extant model has two limitations. First, humans usually refer to the negative consequences of drug use as the reason they stop taking drugs, but the extant model uses drug unavailability to reduce drug seeking. …

Dementia Caregiver Coping Strategies And Caregiver-Care Recipient Relationship Closeness: Associations With Care-Recipient Outcomes, Stephanie Behrensberg

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This project used data from the Dementia Progression Study, a longitudinal, population-based study based out of Cache County, Utah. Statistical models were used to examine the association between caregiver factors, the care environment, and cognitive outcomes in persons with dementia. Mediational analyses were also used to examine if the care environment, inferred for nutritional status, engagement in physical and cognitively stimulating activities, mediated the relationship between the closeness/caregiver coping strategies and cognition in persons with dementia. Results showed that closer caregiver-care recipient relationships were associated with better nutritional status and more engagement in number of cognitively stimulating activities as well …

Development And Validation Of An Agricultural Literacy Instrument Using The National Agricultural Literacy Outcomes, M. Rose Judd-Murray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to develop a standardized agricultural literacy assessment using the National Agricultural Literacy Outcomes (NALOs) as benchmarks. The need for such an assessment was born out of previous research, which found that despite numerous programs dedicated to improving agricultural literacy, many students and adults remain at low or very low levels of literacy. Low literacy levels lead to negative associations with the production and processing of food, clothing, and shelter, as well as misinformed public perceptions and policies. Agricultural literacy researchers recognized that the development of a standardized assessment for post-12^th grade, or equivalent, could unify …

Couple Recovery From Problematic Pornography Use: A Phenomenological Study Of Change Moments And Common Factors, Travis J. Spencer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pornography use has been reported to have harmful effects on relationships and individuals. However, research on effective treatment for problematic pornography use (PPU) is limited. This manuscript reviews the previous treatment literature for PPU and highlights the gaps that need further study. Then, I discuss how I performed a qualitative study of 11 couples who had successfully been treated for PPU in order to analyze the key mechanisms of change that were employed in their recovery process and address the missing gaps in this field of research. The five major emerging themes from this study are Catalysts for Recovery, Foundation …

An Assessment Of Self-Determination Skills In Transition-Age Students With Disabilities Following Instruction Using The My Transition Portfolio Program, Eliza Jex

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The successful transition for students with disabilities into adult roles and activities post high-school, including employment, participation in postsecondary educational opportunities, and inclusion in social activities, continues to be a challenge for these individuals. Research has established that the development of certain skills earlier on can support students with disabilities in making a successful transition into these adult roles. The development of self-determination skills is one such practice. There is a need in the field of education to further research in programs that are available for teachers in providing instruction in self-determination skills. This study sought to establish research on …

Agent-Based Model To Manage Household Water Use Through Social-Environmental Strategies Of Encouragement And Peer Pressure, Ryan James

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Inelastic price responses, demand hardening, and poor public awareness reduce the effectiveness of demand side strategies on water savings. This project quantified phycological household’s factors of attitudes, peer support, opportunities on water conservation with two social-environmental management strategies of encouragement and peer pressure. An agent-based model was populated with data for Logan, Utah using surveys, municipal billing, aerial imagery, weather monitoring stations, and flow, frequency, and durations of appliance use data. Results indicated those households with higher attitudes, peer support and opportunities saved the most water while peer pressure saved more than encouragement when using small and diverse social networks …

The Effect Of Joint Training On Knowledge And Attitudes Of Career And Technical Education And Special Education Professionals, Crystal Emery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Career and technical education (CTE) is a set of career-focused courses and pathways that provide students with technical skills and knowledge which can lead to future employment and postsecondary education. Concentration in a career and technical education pathway while still in high school supports job exploration for school-age youth and is correlated with higher levels of full-time employment after high school. This is especially true for students with disabilities. Special Education (SPED) is the educational support system for students with disabilities. CTE and SPED professionals have struggled to effectively collaborate to serve students with disabilities. Infrequent and inconsistent communication between …

A Narrative Approach To Educational Video Training, Matthew S. Havertz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teachers often use videos to teach their students, but stories are not used as often in educational videos as they could be. Experts tell us that stories are an important part of teaching and learning. Unfortunately, there is only a small amount of research and no definitive expert agreement about stories used in educational videos. This is especially true for videos used with technical education students, like mechanic students or dental assisting students. In this study, dental assisting students learned how to assist a dentist with a standard cavity procedure after watching a video with or without a story. The …

Depression Mediates The Association Of Disordered Eating Behaviors And Sexual Function In Female Service Members And Veterans, Whitney S. Livingston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Poor sexual function is comprised of diminished sexual desire and arousal, presence of sexual pain, inability to reach orgasm, and low satisfaction. Worse sexual function is associated with disordered eating behavior; however, the mechanism through which this association exists remains unclear. Theory of sexual function suggests that depression mediates the association of disordered eating behaviors and poor sexual function in female service members and veterans, but this has yet to be tested empirically. The purpose of the current study was to examine whether depression mediated the association of disordered eating behaviors and sexual dysfunction.

Participants (N=511) were partnered …

The Political Business Cycle: Endogenous Election Timing & Hyperbolic Memory Discounting, Jake R. Cottle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the models analyzed in this paper, there exists an incumbent politician with one objective, two choices, and voters who remember the past differently. The politician's primary goal is to get reelected, which is done by maximizing the number of votes on the day of election. The politician can increase their chances of reelection if they influence the state of the economy over time and ensure the economy is in its 'best' state on the days leading up to the election.

In conducting this research, I wanted to study how different rates of memory decay influences the choices the politician …

Evaluating The Effectiveness Of Livestock Guardian Dogs: Loss-Prevention, Behavior, Space-Use, And Human Dimensions, Daniel Kinka

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Livestock guardian dogs – or “LGDs” – are commonly used by domestic sheep ranchers and reduce the need for killing wild carnivores to protect livestock. LGDs are mostly used in the United States to reduce the number of livestock killed by coyotes, but whether they can prevent killing by larger carnivores like wolves and grizzly bears is unclear. It is important to identify which behavioral traits and LGD breeds work best for guarding livestock so that ranchers can protect their stock and environmentalists can enjoy a greater number of wild animals on the landscape. This study investigated the effectiveness of …

The Impact Of Collaborative Behavioral Health On Treatment Outcomes Of Diabetes, Adam M. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A current body of research is finding significant connection between biological, psychological, social, and spiritual factors in health and wellbeing. Some studies have found significant improvements in treatment outcomes for patients who received medical treatment in collaboration with psychosocial therapeutic treatment. In this study, I sought to observe the impact collaborative treatment had on patients with diabetes who were treated at a community health center. I compared the treatment outcomes of a group of patients who received a collaborative treatment, looking to see if their overall health (measured by A1c, a diabetes severity marker) and medical utilization (or their number …

Examining The Effects Of Familism On The Association Between Parent-Adolescent Conflict, Emotion Regulation, And Internalizing Problems Among Latinx Adolescents, Kenia Carrera

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Latinx adolescents report higher levels of anxiety and depression symptoms (i.e., internalizing symptoms) compared to other ethnic groups. Research studies primarily conducted with European American youth have concluded that difficulties in emotion regulation and parent-adolescent conflict are associated with an increased risk for youth internalizing symptoms. Additionally, an important Latinx cultural value, familism, has been identified as a protective factor for internalizing symptoms for Latinx adolescents. Therefore, the current study examined how familism, parent-adolescent conflict, and difficulties in emotion regulation interact to influence the development of internalizing symptoms among Latinx adolescents. It was hypothesized that (a) parent-adolescent conflict and difficulties …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study focused on the types of messages female middle school students receive about their gender from their peers. Specifically, it looked at microaggressions, which are sexist messages from peers, and microaffirmations, which are positive and affirming messages from peers. There were four goals of this study. First, to check if the Students Affirming Girls in Middle School scale (SAG-MS), a scale created for this study, could consistently measure microaggressions and microaffirmations. Second, to look at the relationship between when girls experience puberty and microaggressions and microaffirmations. Third, to measure any differences in the number of microaggressions and microaffirmations girls …

Adult Attention-Deficit/Hyperactivity Disorder (Adhd): Relationship Between Parental Symptomatology, Child Behaviors, And Parenting Behaviors, Robyn Jeppson-Frandsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adults with attention-deficit/hyperactivity disorder (ADHD) experience impairment in cognitive, scholastic/vocational and interpersonal domains. The goal of this study was to gain more information how adult ADHD symptomatology impacts parenting behaviors, specifically, overreactivity and laxness. This study found that parental ADHD symptoms were associated with greater overreactive parenting behavior. Differences between mothers and fathers were assessed and no significant difference in ADHD symptomatology or parenting behaviors were found. The combination of adult ADHD symptoms and child behavior, above and beyond parental depression, was found to be a statistically significant predictor of parental overreactive behavior, while this was not the case for …

Standards-Based Grading: A Correlational Study Between Grades And End-Of-Level Test Scores, Tyler R. Poll

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As students move from grade level to grade level and onto college, their grades have an impact on the number of opportunities available to students. The competition for entering college and earning a scholarship are at an all-time high and the grades students earn have a direct impact on future opportunities. Grading practices vary by teacher causing students’ grades to mean different things.

Standards-based grading practices focus on removing teacher bias and puts emphasis on the learning students can demonstrate. Students are given assessments to determine learning and are given multiple opportunities to show what they have learned. Emphasis is …

Landscape Of Stress: Does Drought Prevail Over Anthropogenic Activity In Influencing Cortisol Levels And Fitness In The Pacific Fisher?, Jennifer R. Kordosky

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fishers (Pekania pennanti) are a species of concern in the Sierra Nevada Mountains of California. Cortisol is a glucocorticoid hormone released to mobilize energy in response to stress and has been used as an indication of an individual’s physiological response to its environment. By collecting samples of fisher hair and measuring an individual’s cortisol, we examined the physiological stress response of the animals to human disturbances (housing density, road density, habitat type, and silvicultural treatements) and drought (tree mortality) in their home ranges. Using AICc model selection, we found that levels of tree mortality within a fisher’s home …

Narrative Identities Of Early-Return Missionaries From The Church Of Jesus Christ Of Latter-Day Saints, Jillian Ferrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Leaving home to become a missionary is important for many young adults in The Church of Jesus Christ of Latter-Day Saints (CJC). Some missionaries return home from their missions before their anticipated return date and struggle to make sense of who they are while facing judgment from members within the church communities and families. Little is known about the experience of identity development for early return missionaries (ERMs). There have not been many chances for ERMs to share what it means to them to have come home early from their mission. This study investigated the process of how ERMs make …

Youth Prevention Programs: A Framework For Conducting Mediation Meta-Analyses, Morgan A. Kawamura

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Often for prevention program designs, researchers are interested in understanding the processes through which a program impacts a targeted outcome. Mediation analysis assists in identifying not only how a program influences an outcome, but also which intermediate variables (i.e., mediators) cause the effects between a program and an outcome to occur. Mediation analysis explains why a program works, which is useful for program developers in creating effective prevention and intervention-based programs.

To make use of mediation analysis findings for preventive intervention programs, researchers need a comprehensive understanding of the mediators between various programs and outcomes. However, a comprehensive examination into …
