Validation Of A Brief Prosody Rating Scale For Children With Autism Spectrum Disorder, Sarai S. Holbrook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Differences in the speech prosody, or "melody" of speech, of persons with autism spectrum disorder (ASD) have long been noted by researchers. Yet, despite many studies, researchers have not identified a universal description of speech prosody in ASD. It may be flat or monotonous, not different from typical, or overly variable. However, atypical speech prosody can immediately set someone apart from their peers. This distinction could negatively social, academic, and vocational interactions. For those persons with ASD whose speech prosody is different from typical and interferes with daily functioning, valid, reliable, and efficient assessments of speech prosody are needed. Currently, …

The Effects Of Gene Therapy In An Ovine Osteoarthritis Model, Crystal Collier

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humans rely on the health of their joints for stability and mobility in daily life. In a normal, healthy functioning joint, complex processes maintain joint tissues, including remodeling, lubrication, and immune function among many other tasks. Osteoarthritis (OA) is the most common joint disorder in the U.S. It becomes most prevalent in adults 60+ years of age and causes decreased mobility, discomfort, and in some cases, excruciating pain. In the biological processes of osteoarthritis, the metalloproteinase enzymes responsible for the degeneration of cartilage are upregulated. The inhibitors of metalloproteinase activity are known as Tissue Inhibitor of Metalloproteinases (TIMPs), which keep …

An Analysis Of Syntax Exercises On The Performance Of Cs1 Students, Shelsey B. Sullivan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Students in introductory programming classes (CS1) generally have a difficult time learning the rules of programming. Although the general concepts of programming are relatively easy to learn, it can be difficult to learn what exactly can be typed in what order, which is known as syntax. To attempt to help students overcome this barrier, a study was conducted that introduced exercises into a CS1 class which taught the programming syntax in simple steps. The results of this study were obtained by analyzing the keys the students pressed, the errors of their code, their midterm exam scores, and their responses to …

Rumination And Quality Of Life Among Northern Plains Indians, Devon S. Isaacs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Native Americans (NAs) share unique risk factors for poor mental health. In response, mental health providers must address barriers to treatment while making the most of low resource situations. One way to increase usefulness of treatment is to address the mechanisms underlying multiple mental health disorders. Rumination is a style of thinking marked by repeated thoughts about distress and is well-recognized as a diagnostic factor for underlying disorders in the general population. Secondary data from the Mood Disorder Assessment Validation with Northern Plains Indians (NPI) pilot study was used to examine the relationship between rumination and anxiety, depression, and substance …

Early Adolescent Gifted And Talented Students And Their Experience With Bullying, William T. Allen Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bullying, in all its forms (e.g., verbal, physical, cyber, social ostracism), is a continual problem in public schools. It exacerbates the painfully high suicide rate among early adolescent students, especially in the western U.S., with some evidence showing distinctions within the academically advanced gifted and talented (GT) cohort. Research shows GT students (GTs) are bullied at nearly double the rate of the mainstream population. Yet, quantitative statistics indicate GTs and non-GTs suffer comparable rates of trauma internalization, suicide ideation, and suicide. Some quantitative differences do start to appear with further personality distinctions. This points to a possibility that qualitative dissimilarities …

The study used a collective case study design in order to better understand what espoused and enacted pedagogical …

Social Change Engagement And Leadership Development Among College Students, Andrew Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Young people are increasingly in the public view as agents of social change. As suggested in the Social Change Model of Leadership Development, those who develop the seven values of socially responsible leadership (consciousness of self, congruence, commitment, common purpose, collaboration, controversy with civility, and citizenship) are prepared to engage in the leadership process by creating positive social change. Findings from this study suggest that the socially responsible leadership value of citizenship was the value most consistently related to social change engagement. Additionally, social generativity, or the desire to leave a legacy for future generations, as well as participating in …

Teaching Appropriate Feedback Reception Skills Using Computer-Based Training, Seth G. Walker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Feedback is a commonly used intervention to address performance issues in a number of settings. Most research on feedback has focused on manipulating parameters surrounding the delivery of feedback. However, the interaction between those delivering the feedback and a feedback recipient may also influence the impact of performance feedback. The current study investigated the efficacy of training individuals to receive feedback in an appropriate manner using a computer-based training format. Following computer-based training, participants exhibited increases in accuracy of appropriate feedback behaviors when compared to baseline. Participants also demonstrated slight increases in performance on primary job tasks. This study extends …

Supporting Adolescent Mental Health Within School Culture And Curricula: Inviting Adolescents To Utah's Mental Health Conversation, Diana West

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah is facing a mental health crisis. Between 2011 and 2017, teen suicides nearly tripled in Utah and had become the leading cause of death for children ages 10-17. Educators and policymakers are scrambling to provide students with mental health supports in schools, but an incomplete understanding of the challenges that students face can make it difficult to meet their needs. Each year state agencies ratchet up awareness, funding, and the determination to support mental health initiatives, but each year adolescent mental health in Utah becomes more precarious. The purpose of this study is to change the conversation by inviting …

Social Justice Mathematical Modeling For Teacher Preparation, Patrick L. Seegmiller

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Today's math teachers face significant social and political challenges for which they receive little preparation. Mathematics content courses can potentially provide additional preparation in this regard by providing future teachers with experiences to mathematically explore social justice issues. This provides them with opportunities to increase their awareness and sensitivity to social justice issues, develop greater empathy for their future students, and serve as examples for high quality instruction that they can emulate in their future careers. This dissertation recounts the development and revision of three social justice mathematical modeling projects, and shares evidence from student work samples of the ways …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Smartphone based self-tracking fitness applications (apps) like Strava are increasingly becoming a part of recreation experiences in parks and protected areas (PPAs). Recreation research has employed smartphone GPS tracking (SGT) and volunteered geographic information (VGI) to study visitor behavior in PPAs, but little is understood about how smartphones or fitness apps affect visitor perceptions and behavior during their experience.

The first chapter of this thesis is a literature review of recreation survey and behavior research, social-psychology and technology use theory, gamification, and mountain bike social science and recreation-ecology research. The second chapter is formatted for submission to the Journal of …

Harmonic Delay Reduction, Jay E. Hinnenkamp

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Stimuli which, during the life of an organism, acquire the ability to increase the probability of behavior that they follow are called conditioned reinforcers. The concurrent-chains procedure has been used to study conditioned reinforcement for over 60 years. During this time several different models have been developed to explain how stimuli become conditioned reinforcers. The three experiments of this dissertation introduced a new quantitative model of conditioned reinforcement (DRT_H) and tested its predictions against four existing models. The results of Experiment 1 indicated that DRT_H improves upon the accuracy of its predecessor, delay reduction theory (Fantino, 1969), …

Biological Sex As A Moderator Of The Association Of Military Sexual Trauma And Posttraumatic Stress Disorder Total And Symptom Cluster Severity, Hallie S. Tannahill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Posttraumatic stress disorder (PTSD) is a multifaceted disorder comprised of distinct symptom clusters and is commonly diagnosed in military service members/veterans (SM/Vs), particularly in those with history of military sexual trauma (MST). Evidence and theory suggest that females and males may have different traumatic responses following MST, though research investigating this association has limitations, such as modeling the sexes separately or not covarying for MST severity. The current study examined the moderating role of sex on the association of MST severity and PTSD total and symptom cluster severity. Participants were 1,161 SM/Vs (female: n = 782, 67.36%) who completed online …

Parenting Styles And Child Outcomes In Puerto Rican Families: A Comparison Of Individual And Dyadic Coding, Jeisianne Rosario Colón

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parenting styles are comprised from three dimensions: warmth, autonomy granting, and demandingness. These dimensions combined form four parenting styles: authoritative, authoritarian, permissive, and neglectful. Forty-nine Puerto Rican families with children 6-11 years participated. Families engaged in several tasks that were coded using the Parenting Style Observation Rating Scale and child outcomes were measured using the Child Behavior Checklist. Overall, parents received high ratings in warmth, autonomy granting, and supportive demandingness, and low scores in nonsupportive demandingness. There were some differences between parents, with mothers exhibiting higher levels of warmth with girls than boys, and higher levels of autonomy granting and …

A Temporal Information-Theoretic Model Of Suboptimal Choice, Paul J. Cunningham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Humans and animals often make decisions not in their long-term best interest. In one example, called suboptimal choice, pigeons sacrifice food for food-predictive stimuli. The study of suboptimal choice can reveal insights into the role of reward-predictive stimuli in maladaptive decision-making that characterizes numerous behavioral disorders. However, there is currently little evidence that rats engage in suboptimal choice, thereby raising questions about the species-generality of suboptimal choice. According to the temporal information-theoretic model, developed in Chapter 2, suboptimal choice emerges when pigeons pay more attention to the bits of temporal information conveyed by food-predictive stimuli than the rate of food …

Development And Validation Of A Synchronous Model To Simulate Skeletal Muscle Damage Due To Spaceflight Ionizing Radiation And Microgravity, Lori M. Caldwell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Astronauts traveling or researching in space are subject to a harsh environment that includes high levels of ionizing radiation and microgravity. Ionizing radiation is dangerous to overall health because it causes double-stranded DNA breaks, increases the production of free radicals or reactive oxygen species, and leads to an enhanced risk of cardiovascular disease and cancer over a person’s lifetime. Similarly, microgravity is hazardous to astronaut health because humans require gravity to maintain a healthy heart and muscular and vascular systems.

Both ionizing radiation and microgravity have been studied individually in previous research, but there is a lack of information on …

Relationship Quality Before, During, And After Stepfamily Education: A Latent Trajectory Analysis, Bryan K. Spuhler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to explore the trajectories of relationship quality for a sample of 777 adult participants attending the Smart Steps: Embrace the Journey stepfamily relationship education course. Rather than assume that all program participants had similar relationship quality trajectories by averaging their scores together in a growth curve analysis, growth mixture modeling was used to allow for a variety of sub-groups (classes), each with a unique trajectory. A prevention science approach was then taken to address possible predictors of each trajectory class in order to identify the risk and protective factors that influence participants’ trajectories.

It …

Applying Sexual Script Theory To Hooking Up: A Latent Profile Analysis Of Predictors And Outcomes Of Class Membership, Mitchell R. Rhodes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to explore relationship between individuals’ characteristics, experiences, personality traits, and thought processes in the contexts of casual sexual behaviors. According the principles of Sexual Script Theory, personality traits and personal thought are creations of cultural beliefs and individual experiences. A sample of 1,142 emerging adults between the ages of 18-24 who had a hooking up experience (i.e., sexual activity outside of romantic relationships).

It was found that the emerging adults in this study could be grouped into three (3) distinct groups based upon their personality traits and their motivations for hooking up. The first …

“What Makes ‘Em Tick?” The Impact Of Parenting Style And Parent-Initiated Motivational Climate On Student Athletes’ Motivation Orientation In The Context Of Intercollegiate Athletics, Logan Kateryna Lyons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Motivation has become a widely studied construct in intercollegiate athletics, as coaches and administrators have sought to maximize the socioemotional and performance aspects of athletic competition. While researchers acknowledge parents as having an important role in the socialization of motivation, research in this area has largely focused on sport-specific parenting practices, failing to account for the broader components of global parenting style that may influence parent-initiated motivational climates, and subsequently the motivational profiles exhibited by developing student athletes. The present study was designed to investigate the relationship among global parenting style, parent-created motivational climate, and student-athlete motivation within the context …

Teacher Questions In The Classroom: The Effects Of Using A Low- To High-Level Questioning Sequence On The Text-Based Reading Comprehension Outcomes Of Low-Performing Students, Shannon Harris Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teacher questioning may be an effective instructional procedure for building students’ reading comprehension. Strategically asking questions at two different levels, low-level (text explicit) and high-level (text implicit), may be needed to assist students to engage in higher order thinking skills.

The purpose of this study was to evaluate the effectiveness of a low- to high-level questioning sequence without or with linking prompts on the text-based reading comprehension outcomes of fifth-grade students who evidenced poor reading comprehension. A secondary analysis was used to determine whether the questioning sequence was effective regardless of students’ interest in the narrative …

Dramatic Play Affordances Of Outdoor Settings For First And Second Grade Children With And Without Disabilities, Nicholas R. Leschofs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Unstructured play is crucial for children’s development. Dramatic play is play involving a transformation of objects, actions, or self-identity. During dramatic play, children may operate at more advanced cognitive levels than they do in non-dramatic play, thereby furthering their cognitive, social, and emotional skills. Interactions among children with and without disabilities are valuable opportunities to further a children’s development.

This study compared dramatic play behaviors among first and second grade children with and without disabilities to determine which play settings encouraged children to engage in quality dramatic play. Eighty-nine six-to-eight-year-olds were observed during lunch recess daily on an inclusive playground. …

The Environmental Impact Of Immigration In The United States, Guizhen Ma

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Population growth increases pressure on the environment. Immigration may be harmful to the environment because it is the major force of population growth in the United States. However, this argument has not been supported by research findings. A few studies on this topic show that locations with higher numbers of immigrants experience better air quality than locations with greater proportions of U.S.-born residents. This research investigated the environmental impact of immigration through three independent studies. First, I tested the relationship between U.S.-born population, foreign-born population, and air quality across all the U.S. continental counties. This study analyzed the air quality …

Exploring Park Quality In Urban Setting With Environmental Justice, Alternative Measurements, And Social Interaction, Shuolei Chen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With rapid urbanization, urban green resources, such as parks have become important assets for quality of life in urban settings. Parks provide urban residents with both physical and psychological health benefits through various mechanisms such as physical activity and social interaction. Quality is an important non-spatial dimension of urban parks and has started to gain attention among researchers. To better understand park quality in an urban setting, additional knowledge should be explored. This dissertation studies the quality of urban parks from three different perspectives: 1) the equal distribution of park quality resources and its relationship to environmental justice issues, 2) …

Family Development And The Marital Relationship As A Developmental Process, J. Scott Crapo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite the commonly held idea that families develop, there is not a theory in common use within the family science field that is developed specifically for the study of the development of the family. Family development theory, developed in the post-World War II era, was used previously, but an inability to be adapted to contemporary families and a lack of scientific utility have kept it from use. Additionally, research on how families develop has not considered how relationships may develop over time.

In this dissertation, I seek to address these holes in the family studies field. I do this over …
