Latent Difference Score Mediation Analysis In Developmental Research: A Monte Carlo Study And Application, Melissa Simone

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Developmental and prevention researchers aim to determine how unhealthy behaviors emerge. Mediation analysis offers a statistical tool that allows researchers to describe the processes underlying early risk and later health outcomes. Among existing longitudinal mediation models, latent difference score mediation stands out due to its unique ability to capture variations in changes both within and across individuals, as well as its ability to examine non-linear change over time. However, the literature currently lacks sample size guidelines for latent difference mediation models, which has proven to make the use of these models difficult. The current project addresses this limitation by offering …

Content Analysis Of Affordances For Social And Emotional Competency Development In Third-Grade Core Reading Programs, Lisa Trottier Brown

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this content analysis study was to identify opportunities embedded in selected reading programs that facilitate the development of social and emotional competencies in the context of literacy instruction. These competencies have been shown to strengthen academic performance and help children learn skills that accelerate success inside and outside of the classroom. The content analysis examined three commonly used third-grade core reading programs to identify content that focuses on social and emotional competencies and instructional processes important in teaching social and emotional skills to children. The study also sought to identify content and instructional processes that might be …

In-Situ Educational Research From Concept To Classroom Implementation: A Multiple Paper Dissertation, David Mark Weiss

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An educational researcher sought to collaborate with a classroom instructor to introduce problem-based learning as a new teaching intervention. First, a classroom instructor was approached to consider how a problem-based learning instructional approach might fit with their existing curriculum plan. The researcher and the classroom teacher used a discussion framework to decide together how to best design a professional learning course meant to prepare the teacher to use the new techniques in their classroom. The teacher took the professional learning course and subsequently designed his own problem-based learning course. That course was then delivered to undergraduate students in a college …

Advancement To The Highest Faculty Ranks In Academic Stem: Explaining The Gender Gap At Usu, Helga Van Miegroet

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Science and technology (S&T) disciplines at universities are still largely dominated by men, and few women are found in the highest employment ranks. Using the faculty data from Utah State University, this thesis explores the factors that help explain the difference in career trajectory between men and women in the S&T colleges. While there were few women in S&T colleges prior to the 1990s, more women have been hired since then, and the lower ranks of the faculty corps are starting to reflect the gender composition of the doctoral degree holders in the different fields. This is not the case …

Marginal Mediation Analysis: A New Framework For Interpretable Mediated Effects, Tyson S. Barrett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mediation analysis is built to answer not only if one variable affects another, but how the effect takes place. However, it lacks interpretable effect size estimates in situations where the mediator (an intermediate variable) and/or the outcome is categorical or otherwise non-normally distributed. By integrating a powerful approach known as average marginal effects within mediation analysis—termed Marginal Mediation Analysis (MMA)—the issues regarding categorical mediators and/or outcomes are, in large part, resolved. This new approach allows the estimation of the indirect effects (those effects of the predictor that affect the outcome through the mediator) that are interpreted in the same way …

Utilizing A School-Based Treatment To Address Socially Anxious Elementary School Students, Mckell Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite the availability of promising clinic-based programs, youth exhibiting socially anxious behaviors rarely receive the treatment they may need. Those that do get treatment, often do so in the school setting. Thus, the demand for effective interventions to address those needs in the school-setting is growing. The present study investigated the effects of a modified CBT intervention, delivered in the school setting, on positive peer interactions and self-rating social anxiety. Results showed that the treatment package provided an increase in positive peer interactions across all four participants, as well as a decrease in self-rated anxiety behaviors.

A Qualitative Analysis Exploring The Development Of Problematic Sexual Behaviors In Adolescent Males With Developmental Disabilities, Maria J. Watters

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adolescents with developmental disabilities (DD) experience regular physical and sexual development. Some adolescents with developmental disabilities engage in problematic sexual behaviors (PSB). In order to be able to address the needs of this population in terms of prevention of PSB, and provision of effective treatment after PSB has begun, their experience must be understood and contributing factors identified. It is with this in mind that this study was designed, with the purpose being the exploration of the experiences of adolescents with DD who have engaged in sexually problematic behaviors, including compulsive or addictive patterns of behavior, and to identify the …

Examining The Effect Of A School-Based Treatment On Anxiety For Latino Students, Emilie J. Larsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the efficacy of a brief culturally and instructionally modified cognitive behavioral therapy program for five anxious Latino/a youths ages 8-11 years in an elementary school setting. Each student exhibited anxiety in a classroom setting as reported by their teachers and parents or guardians. A noncurrent multiple baseline design was implemented using A-B replications to assess the effects of baseline and treatment on daily self-report student distress ratings as well as daily teacher rated distress, academic engagement, and work completion. All participants completed the Revised Children’s Manifest Anxiety Scale-2 pre- and post-treatment as well as a Children’s Intervention …

Does Neighborhood Context Matter? A Multilevel Analysis Of Neighborhood Disadvantage And Sleep Health, Carlyn E. Graham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Childhood is one of the most important stages for physical and cognitive growth during the life course. For young children, sleep is one of the major contributors to healthy development; poor sleep quality and short sleep duration can detrimentally affect developmental progress. In addition to physiological contributors to poor sleep, social factors may affect young children’s sleep. Prior findings suggest that demographic and socioeconomic characteristics, such as race and parent’s educational attainment, may contribute to sleep health for children. Furthermore, limited prior research suggests that neighborhood attributes may affect sleep for both children and adults alike. To my knowledge, no …

Changing Nonhuman Impulsive Choice, C. Renee Renda

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Preference for smaller-sooner over larger-later rewards characterizes one type of impulsivity—impulsive choice. Impulsive choice is related to a number of maladaptive behaviors including substance abuse, pathological gambling, and poor health behaviors. As such, interventions designed to reduce impulsive choice may have therapeutic benefits. The purpose of this dissertation was to explore two methods to change nonhuman impulsive choice. In doing so, we hope to provide a baseline that future research can use to assess variables that are less amenable to human research (e.g., drug self-administration following reductions in impulsive choice). In Chapter 2, we failed to reduce nonhuman impulsive choice …

Characterization Of Lactose Fatty Acid Esters For Their Microbial Growth Inhibitory Activity And Emulsification Properties, Seung-Min Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sugar esters, substances made from bonding fatty acid tails to a sugar head, can play a number of key roles in food systems from antimicrobial agents to emulsifiers. These unique and very useful properties result from their water-loving and water-avoiding ends. Lactose, a sugar found in milk, based esters are important, as they are environmentally friendly and inexpensive, however, they are not very well understood. I created four different types of lactose esters: lactose monooctanoate (LMO), lactose monodecanoate (LMD), lactose monolaurate (LML) and lactose monomyristate (LMM), and then compared them to each other to see which would be the best …

Using Social Cues To Influence Fruit And Vegetable Intake In College Students, Elizabeth A. Nix

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

People often base their behaviors on social norms—what they think others do or approve of. This is likely true of fruit and vegetable (FV) intake as well. College students typically don’t get enough FV. We attempted to encourage FV eating by providing students with messages or demonstrations that eating FV is normal. First, we tried to encourage FV intake by providing students with messages regarding the average skin carotenoid concentration and where they fit within their peers (Chapter II). Carotenoids are compounds found in FV that cannot be made by the body, making them an estimate of FV intake. We …

Lifetime Estrogen Exposure And Brain-Derived Neurotrophic Factor: Implications For Cognitive Decline In Late Life, Joshua M. Matyi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache County Study on Memory in Aging (CCSMA) is a longitudinal population-based study which took place in Cache County, Utah. The study followed 5092 older-adult residents (aged 65+) for approximately 12 years to examine risk and protective factors for dementia. Participants completed dementia screening and follow-up assessments across four triennial visits. Additionally, researchers gathered information regarding demographics, reproductive history (e.g. age of menopause; hormone replacement therapy [HRT]) and other health-related factors, such as physical activity. Genotyping of DNA was completed for a genetic variation of genes for brain-derived neurotrophic factor (BDNF), a protein found in the brain associated with …

Acculturation And Language Use In Intimate And Sexual Relationships Among Chinese Bilinguals, Tianyi Xie

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

People of Chinese heritage often face complex challenges because of the conflicting values from China and America, especially on sexuality. Through two thousand years of socialization, Chinese culture grew to endorse conservative sexual values and gender roles. In traditional Chinese culture, women are expected to remain chaste and play submissive roles in marriage. Sexuality is treated as a taboo topic that should not be discussed directly. Asian American youth who endorse less traditional Chinese values experience lower sexual satisfaction, lower confidence in their own abilities, and higher adherence to traditional gender roles. Language has also been found to potentially influence …

Novel Statistical Models For Quantitative Shape-Gene Association Selection, Xiaotian Dai

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Other research reported that genetic mechanism plays a major role in the development process of biological shapes. The primary goal of this dissertation is to develop novel statistical models to investigate the quantitative relationships between biological shapes and genetic variants. However, these problems can be extremely challenging to traditional statistical models for a number of reasons: 1) the biological phenotypes cannot be effectively represented by single-valued traits, while traditional regression only handles one dependent variable; 2) in real-life genetic data, the number of candidate genes to be investigated is extremely large, and the signal-to-noise ratio of candidate genes is expected …

Rancher Perceptions Of Ecosystem Services From Rangelands Of The Intermountain West, Elisabeth C. York

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rangelands within the Great Basin are responsible for the provision of multiple resources that humans depend on for a variety of reasons. Ranchers in this region are dependent on public lands to remain economically viable in their cattle operations. As a majority of land in this region is publically owned, there are varying interests at play in what should and could be the focus of management. Ranchers are charged with implementing strategies aimed at conserving these landscapes and their motivations for what to manage may significantly influence resource provision from Intermountain West ecosystem.

In this study, I sought to understand …

Emotional Experience During Couple Support Interactions: The Role Of Attachment Anxiety And Avoidance, E. Megan Lachmar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Marriage and Family Therapy clinic at Utah State University conducted a study called the Relationship Checkup in which couple data was collected in an initial 2-hour session and feedback was provided for them in a follow-up 1-hour session. This checkup included completing self-report surveys, having an in-person interview, as well as couple interactions. The current study was carried out within the context of this broader relationship checkup, focusing on the couple support interactions, in which partners discussed a personal issue they would like to change about themselves.

Although a substantial amount of attention has been given to the role …

Extracting And Visualizing Data From Mobile And Static Eye Trackers In R And Matlab, Chunyang Li

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Eye tracking is the process of measuring where people are looking at with an eye tracker device. Eye tracking has been used in many scientific fields, such as education, usability research, sports, psychology, and marketing. Eye tracking data are often obtained from a static eye tracker or are manually extracted from a mobile eye tracker. Visualization usually plays an important role in the analysis of eye tracking data. So far, there existed no software package that contains a whole collection of eye tracking data processing and visualization tools. In this dissertation, we review the eye tracking technology, the eye tracking …

Allowing The Untellable To Visit: Investigating Digital Folklore, Ptsd And Stigma, Geneva Harline

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the introduction of 2012 issue of The Journal of Folklore Research, Diane Goldstein and Amy Shuman issue a “call to arms for folklorists … to concentrate on the vernacular experience of the stigmatized.” (Goldstein and Shuman, 2012:116). Drawing on this call to arms, this thesis investigates how Post-Traumatic Stress Disorder (PTSD) is portrayed in social media through memes and captioned images. I argue that the genres of memes and captioned images in digital folklore work to help mitigate the stigma of PTSD because the veneer of anonymity in the digital world allows people with PTSD to be willing …

Exploring The Effect Of Disability Microaggressions On Sense Of Belonging And Participation In College Classrooms, Lynsie Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Microaggressions are a form of interpersonal discrimination towards marginalized groups that are often ambiguous in nature and delivered unintentionally. The subtleness of these attacks on identity can make them difficult to recognize and address.

Emerging research reveals that the targets of microaggressions are experiencing negative effects on their wellbeing; however, the bulk of existing literature on this topic only addresses microaggressions perpetrated towards racial minority or LGBT individuals. Little is known about pervasiveness and potential impact of microaggressions directed towards people with disabilities- particularly in academic contexts.

This study pilots a measurement tool, the Microaggressions Towards Students with a Disability …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With approximately 65 stillbirths occurring each day in the United States, a significant number of parents are left to navigate a difficult grieving process. An event like stillbirth presents many individual and relational challenges. For this study, researchers focused on the hospital experience for couples following notification of stillbirth. Interviews were held with 8 couples that had experienced stillbirth within the past 10 years. Researchers wanted to know what similarities and differences existed in how mothers and fathers described the clinical encounter.

The data for this study were collected through interviews. Couples were encouraged to share as much or as …

Examining The Read-To-Write Strategy And Its Effects On Second Grader’S Writing Of Sequential Text, John Neal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Writing is so important. It is important in school and in our careers; writing is found to be helpful physiologically and psychologically. Experts wonder, with writing so important, why is writing not being adequately taught in the schools. The answer may be that writing is complex and teaching it is even more complex. The Read-to-Write Strategy is a writing model based on the study of exemplary models of text and children are explicitly taught how to write the way an author writes through a process of the teacher modeling how to write this way; the teacher sharing the writing task …

Changing The World Through The Word: Developing Critical Consciousness Through Multicultural Children’S Literature With Critical Literacy In An Elementary Classroom, Hyekyoung Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to explore how fifth graders develop critical consciousness regarding the self and the world through critical literacy approaches using multicultural children’s literature. I employed Lewison, Flint, and Van Sluys’ four dimensions of critical literacy. I used a qualitative case study to design, frame and conduct this study in order to collect data and examine students’ cultural patterns including values, beliefs, behaviors, and language that they enacted in the critical literacy practices. I collected data through classroom observations, semi-structured students and teacher interviews, informal conversation, researcher’s reflective journal entries and field notes, and student-made artifacts. …

Renewable Energy: Prospects, Politics, The Public, And Proximity, Peter G. Robertson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The way our electricity is generated is in a period of rapid change; in the United States and many other countries the system is becoming less reliant on coal based power systems, while natural gas and solar and wind power are becoming more and more important. Technological advances have made solar and wind power more efficient and increasingly cost-effective. While these changes to the electrical system come with great benefits, such as less pollution, these technologies are not free of impacts. The electrical system is inseparable from our modern lifestyle, and because the system is so large this transition will …

Integrating Social And Ecological Methods To Assess And Inform Park Monitoring And Management, Kelly A. Goonan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Managing outdoor recreation requires that managers do the following: (1) consider the user experience, environmental and cultural resources, and type and intensity of management actions; (2) specify desired conditions to be maintained, monitor conditions, and take appropriate action if unacceptable impacts occur; (3) adapt to new conditions and information; and (4) exercise good judgment based on their professional experience and the best information available to them. Social science studies of visitors and studies of significant recreation resources like campsites are important sources of information for managers and are commonly used in parks and protected areas to support planning and decision-making. …

Relationship Between The Built Environment, Physical Activity, And Chronic Disease Among Individuals With Disabilities In Rural Communities, Nicholas F. Tanner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Increased risk for chronic disease is closely associated with individual nutrition, tobacco use, and physical inactivity. This thesis focuses on physical activity as a means of preventing select chronic diseases. A major barrier preventing engagement in physical activity is the built environment. Populations residing in rural environment are not afforded the abundance of opportunities for physical activity prevalent in most urban networks. Of the demographic living in rural environments, individuals with disability face additional barriers to physical activity than those without disability. This leads to a higher prevalence of chronic diseases associated with sedentary lifestyles among populations with disability. Few …

Building Community Using Experiential Education With Elementary Preservice Teachers In A Social Studies Methodology Course, Stephanie L. Speicher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There is urgency for teacher educators to instruct preservice teachers in the core tenants of social justice education. This urgency is based upon the ever-growing shift in the American demographic landscape and the responsibility of educators to teach for equity, justice, identity and community within classrooms across the U.S. Preservice teachers report feeling inadequately prepared to educate for social justice when entering the formal classroom setting. Feelings of incompetence in social justice teaching pedagogy expressed among preservice teachers coupled with minimal examination in the literature of the effects of teacher education practices that aid in the readiness to teach for …

From "Struggling" To "Example": How Cross-Age Tutoring Impacts Latina Adolescents' Reader Identities, Dustin H. Drake

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Educators and policy makers have shown a consistent concern over the achievement gap. In academic assessments, Latino students have demonstrated lower achievement than their peers, particularly in reading scores. Many researchers attribute the existence of the achievement gap to a school system that ignores Latino culture or perpetuates struggles in Latino students’ reading by being culturally insensitive. Multiple theorists suggest that school systems that better understand Latino identities will be better at instructing Latino students. Many programs, including Latinos in Action, have been implemented in attempts to close this gap. The Latinos in Action program utilizes Latino adolescents as peer …

Incidental Vocabulary Acquisition In Middle School: An Examination Of Three Instructional Conditions, David B. Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The importance of vocabulary knowledge gained through incidental learning is well documented. The growth of incidental vocabulary knowledge is especially crucial for middle school students due to the complex words encountered in their studies. However, research on incidental vocabulary acquisition for middle school students is lacking. The purpose of this study was to compare the relative effectiveness of three instructional conditions (reading, writing, and reading and writing) on incidental vocabulary acquisition and retention with middle school students in an English as a first language (L1) environment.

In this within subjects repeated measure study, 263 eighth-grade participants received treatment in three …
