Reimagining Culture With Youth: Relationship And Representation In Culturally Centered Learning Environments, Lili Yan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation intends to develop an understanding of how culturally centered learning environments impact youth’s relationship with culture. Working alongside a multicultural team of researchers, educators, and designers who came together with a shared goal of designing curricular activities to engage sixth graders with culture, I followed 12 sixth graders for a school year to understand their development of relationships with culture. I (re)conceptualize the holistic process of learning and engagement with culture as Ti-Wu and propose a cultural learning model that helps us understand how youth develop multiple relationships with culture. I further share how multimedia technology mediates youth’s …

Ars, Virtus, Impetus: Gladiatorial Training And Roman Legionaries, Daniel Porter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 105 BCE, the Roman consul Publius Rutilius Rufus employed gladiatorial training for his legionaries. This thesis examines the physiological and psychological consequences of this style of training on the human body in an effort to understand why these particular soldiers were so effective. I used experiential testing alongside primary and secondary source research to examine how this process better prepared Roman troops for engaging in actual combat.

Trial Spacing And The Conditioned Motivational Effects Of A Food-Predictive Cue, Gabrielle M. Sutton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Stimuli in the environment can come to influence motivation and behavior through a process known as Pavlovian conditioning. During Pavlovian conditioning, stimuli in the environment come to predict the availability of a reward. Two different procedures are used to investigate how stimuli can modify ongoing behavior and reward consumption, known as Pavlovian-instrumental transfer and potentiated feeding, respectively. In other procedures that investigate how stimuli modify behavior, certain time intervals during Pavlovian training can influence how much a stimulus can modify behavior. One of those intervals is the time between the presentation of a stimulus and the associated reward. This interval …

Finding Their "Why": Examining The Development Of Sense Of Purpose During The University Years And Its Role In Student Well-Being, Michael Q. King

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nearly 20 million students were expected to be enrolled for college or university studies during the 2020-2021 academic year. These institutions often advertise to prospective students that, in addition to advancing their education, they will discover their purpose. Given previous work and current interest in sense of purpose, additional attention on sense of purpose in the university setting is worthwhile. In addition, as many university stakeholders are concerned about an ongoing mental health crisis, a further examination into a developmental construct (i.e. sense of purpose) thought to provide a “sheltering fortress in a world of constant threat” seems …

Critical Democratic Education: A Case Study On Controversy Deliberation And Its Effects Among Pre-Service Elementary Teachers, Shouqing Si

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The state of democracy facing expanding political division and pervasive racial and social inequalities. Discussing and deliberating controversial social and political issues functions help foster students' civic contribution. I conducted a qualitative case study and recruited 14 participants, with whom I conducted interviews, self-reflection, observation, and autoethnography. I targeted the primary research question: How do pre-service elementary teachers experience and get influenced by discussing social and public issues? I broke it down to six operational questions:

1. What issues are considered controversial by pre-service teachers in their future social studies classrooms?
2. What challenges do pre-service teachers perceive in controversial issues teaching? …

Cross-Boundary Stewardship In Protected Area Centered Ecosystems: Perceptions Of Success And Characteristics Of Cooperative Engagement, Ryan D. Tarver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The legal boundaries of protected areas, such as national parks are established and enforced by humans. Therefore, jurisdictional boundaries are ultimately have human meaning but not necessarily ecological relevance as natural phenomena such as watersheds and wildlife habitat often extend beyond a jurisdictional boundary. When considering the extent of natural system, we find that protected areas only make up part of a given ecosystem. The result is a large expanse of lands that fall under a various ownership types that include both publicly and privately designated tracts of land. This presents a management challenge when attempting to manage at the …

We Travel Together: Examining The Drivers And Functions Of Animal Movement In Biotic Seed Dispersal, Binod Borah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plants and frugivorous animals exist in mutually beneficial relations, as these animals feed on fruits, ingest the seeds, and carry them away from the parent trees. Such dispersion of seeds over space helps them colonize new habitats, escape high mortality rates near their parent trees, and avoid competition with conspecifics. Therefore, seed dispersing animal movement can be critical for the persistence of plant populations. Yet what drives such seed disperser movement is often less understood and how it affects seed dispersal is little explored. In my dissertation, I investigate multiple drivers of seed disperser movement, link movement to potential seed …

Exploring The Process Of Mindful Breathing With Stressed Mothers, Caleb D. Farley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mindfulness exists in many parenting and family interventions and are intended to decrease stress, improve familial relationships, and indirectly improve child wellness, and these mindfulness-based interventions (MBI) are relatively effective at doing so. However, critical issues remain related to designing effective and useful interventions for school-based and other community practitioners. Specifically, research has not demonstrated clear relationships between parent mindfulness practice increasing generalized mindfulness behaviors (i.e., awareness and acceptance), experiencing subsequent parental stress reduction, and reporting decreased behavior problems in children. The current study examined these relationships between practicing mindfulness and experiencing changes in parents’ mindfulness process, wellbeing, and perceptions …

The Relation Between Racial Attitudes And Facets Of Impulsivity, Diana M. Perez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Racism is an ongoing issue in U.S. society. The present study examined the relation between racial attitudes and two types of impulsivity (i.e., behavioral inhibition and delay discounting). Prior research has not touched upon the relationship between impulsivity and racial bias; nonetheless, the factors that influence the ability to interfere with automatic thinking and bad decision making may be a way to address racial bias. One hundred eighty-seven White adult participants were recruited from Amazon Mechanical Turk (MTurk), an online survey taking website. The value participants place on future rewards (i.e., delay discounting) and the ability to stop their behavior …

Student Perceptions Of Male And Female Instructors In A Post-Secondary Welding Course, S. Kjersti R. Decker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Agricultural mechanics and welding have traditionally been perceived to be careers reserved for males, yet more females have entered professions using welding such as agricultural education. This research was developed because of the lack of gender research in welding. The purpose of this study was to examine students’ perceptions of learning from a male instructor versus a female instructor in a post-secondary welding course. We examined associations and differences between students’ preference of a male and a female welding instructor as well as individual self-efficacy and perceptions towards using welding technology. The population for this study was undergraduate students and …

Connections Between Mathematics And Computational Thinking: Kindergarten Students' Demonstration Of Mathematics Knowledge In A Computational Thinking Assessment, Lise E. Welch Bond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research shows that computational thinking can be used with kindergarten mathematics instruction, however we still do not know much about how specific math knowledge is related to computational thinking and if (and if so, how) children's mathematical knowledge is related to students' performance on computational thinking assessments. This student fills this knowledge gap by examining the following research questions: (1) How are kindergarten students' mathematical knowledge (MK) and computational thinking (CT)MK and CT operationalized during a CT assessment? In what ways, if any, do MK and CT co-occur, and (2) How do students' mathematical knowledge and co-occurring mathematical knowledge and …

Teachers’ Learning Of Fraction Division With Area Models, Michael Leitch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research shows that fractions concepts play an essential role in the learning of later mathematics. However, fractions are notoriously difficult to learn and difficult to teach. Division with fractions is a frequent subject in mathematics education research because division is the most conceptually difficult of the four basic arithmetic operations and rational numbers are the most conceptually difficult numbers in K-12 mathematics curricula.

In the U.S., teachers are generally proficient with mathematical procedures, but often have difficulty explaining the concepts underlying the procedures. Research indicates a positive association between student learning and teachers’ depth of conceptual understanding of mathematics. Thus, …

Board Certified Behavior Analysts In Public Schools: Challenges And Opportunities, Danielle Lyons

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Board Certified Behavior Analysts (BCBAs) can play an important role in schools. The purpose of this study was to survey BCBAs who self-identify as working in public schools in effort to learn more about their experiences working in this setting. This paper is meant to spark further discussion and research on how BCBAs can be more effective in schools through training and supervision, collaborating with school administrators on systems-level concerns, resolving ethical concerns, and clarifying roles and responsibilities in public schools.

Who Is Accessing Ipse Programs? Examining The Demographics Of Students Enrolled In Inclusive Post-Secondary Education, Madison Heider

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This initial survey study was designed to examine the demographics of students attending inclusive post-secondary (IPSE) programs for students with intellectual and developmental disabilities (IDD). IPSE programs are designed to deliver a similar, if not identical, collegiate experience to students with IDD as their peers without disabilities. Previous research has investigated IPSE programs and their impact, but there is limited information regarding student makeup. The researchers looked to identify the diversity of students beyond their disability categories; research questions surrounded student diversity, barriers to accessing IPSE programs, and what, if anything, programs do to increase diversity within their programs. The …

Recreational Fishing Participation In Utah: Comparing Active And Non-Active Angler Constraint Perceptions With The Use Of License Purchase Data, Will Rempel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As a leisure activity, recreational fishing provides numerous social, physical, and psychological benefits to its participants. It can also provide socioeconomic opportunities to specific communities, and as an outdoor activity can create support for natural fisheries resources and public lands. License and equipment taxes are also important funding mechanisms for state wildlife managers. Though fishing participation as a percentage of the population has overall decreased in the last century, there is a recent increase in fishing participation. However, participation dynamics result in a shifting cycle of entries, departures, and re-entries to the sport. In an effort to maintain participation and …

Differing Mastery Criteria Effects On Maintenance Of 1-Step Instruction Following In Children With Disabilities, Kyle Wagner

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The majority of Early Intervention clinics throughout the United States are currently using a practice that is not considered evidence based. When teaching skills to children with developmental disabilities, clinicians assign an accuracy standard for those skills. The most common accuracy standard, called a “mastery criterion,” is 80% across three teaching sessions. There is little to no evidence to support using this specific mastery criterion. The purpose of this study was to add more research regarding this topic, and how it affects how the skills taught maintain over time when teaching has ceased for a specific skill. Two children were …

Young Children's Nutrition, Growth, And Cognitive Development In The Ecuadorian Amazon, Kristin N. Murphy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The first few years of life are viewed as a critical period for development. Children who do not grow and develop well in these early years can experience life-long negative implications. Many children under the age of five in Ecuador suffer from high rates of malnutrition, stunting (low height-for-age), and delayed cognitive development. This dissertation aims to better understand why children from Ecuador, specifically from the Amazon region, are experiencing such high rates of delayed development. Fifty children and their mothers living in the Amazon region of Ecuador participated in this research study.

First, interviews were conducted by an Ecuadorian …

Statistical Challenges And Methods For Missing And Imbalanced Data, Rose Adjei

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Missing data remains a prevalent issue in every area of research. The impact of missing data, if not carefully handled, can be detrimental to any statistical analysis. Some statistical challenges associated with missing data include, loss of information, reduced statistical power and non-generalizability of findings in a study. It is therefore crucial that researchers pay close and particular attention when dealing with missing data. This multi-paper dissertation provides insight into missing data across different fields of study and addresses some of the above mentioned challenges of missing data through simulation studies and application to real datasets. The first paper of …

The Role Of Dysfunctional Beliefs And Attitudes About Sleep (Dbas), Rumination, Psychological Inflexibility, And Insomnia Among College Students, Guadalupe G. San Miguel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of the study was to understand additional variables that play a role between insomnia and the inability to stay present with internal feelings/emotions (i.e., psychological inflexibility) among college students. These variables that were predicted to help explain this relationship include dysfunctional sleep-related cognitions and insomnia rumination. To do this, college students were surveyed online at the start of the study and one month later. In addition, to be included in the study they must have been enrolled in a 2- or 4-year university, have access to the internet, and not diagnosed with another sleep disorder. Participants (n …

Estimating The Effects Of Forms Of Computer-Based Scaffolding In Problem-Centered Stem Instruction, Mason Reed Lefler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Much like Post-Sputnik 1950s era there is a lot of interest in making sure that United States does not fall behind in Science, Technology, Engineering, and Mathematics (STEM) education. STEM learners are often presented with complex problems to solve both as part of their education and their work. Engineering education suffers from student dropout often due to how difficult it is to support students through solving problems. This dissertation is a close look at computer-based scaffolding, a method of supporting learners during problem solving through computer software. The first paper in this dissertation examines and resolves some of the debate …

Responsive Technical Education Curriculum: An Exploratory Case Study Approach Toward Understanding Human Skills Alignment, Kari Lamoreaux

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Globalization and rapid changes in technology have led to a shift in the skills employers need. These changes have resulted in a gap between the skills people have and those required by industry. This exploratory case study sought to better understand the uniquely human skills employers desire and technical educators should teach in order to address this gap in a local context. The study was conducted in four phases. 1) Current literature was analyzed to identify commonly recurring human skills discussed in studies and reports. 2) These skills were then used as search terms in an analysis of occupational advisory …

Data Visualization, Dimensionality Reduction, And Data Alignment Via Manifold Learning, Andrés Felipe Duque Correa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The high dimensionality of modern data introduces significant challenges in descriptive and exploratory data analysis. These challenges gave rise to extensive work on dimensionality reduction and manifold learning aiming to provide low dimensional representations that preserve or uncover intrinsic patterns and structures in the data. In this thesis, we expand the current literature in manifold learning developing two methods called DIG (Dynamical Information Geometry) and GRAE (Geometry Regularized Autoencoders). DIG is a method capable of finding low-dimensional representations of high-frequency multivariate time series data, especially suited for visualization. GRAE is a general framework which splices the well-established machinery from kernel …

The Efficacy And Feasibility Of Web-Based Acceptance-Enhanced Behavioral Treatment For Trichotillomania In Adults: A Randomized Waitlist-Controlled Trial, Leila K. Capel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Trichotillomania, or chronic hair pulling, impacts several aspects of a person’s everyday life and functioning including making it difficult to fully engage in school, work, romantic relationships, and other social relationships. There are several treatment options for trichotillomania and one that is particularly promising is acceptance and commitment therapy-enhanced behavioral therapy (AEBT). Several studies have been done in person and through telehealth and this treatment has helped participants.

Many people in the U.S. struggle with trichotillomania but many people are not able to access treatment for their hair pulling because clinicians are not available in their area, clinicians are not …

Storytelling To Promote Mental Health: A Conceptual Analysis And Application With Acceptance And Commitment Therapy For Depression, Carter H. Davis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mental health treatments can be delivered in many ways. One approach is to use storytelling to communicate healthy practices. While societies across the world have engaged in storytelling for thousands of years, these practices have been used less in the mental health field. The aim of this project was to study the overlap between the areas of mental health and storytelling. We also tested how a storytelling-based mental health treatment could help solve a particular clinical problem. In this case, the problem of people who receive inadequate help for managing depression through medication alone.

We examined one particular mental health …

Together, Our Voices Will Strengthen The Weaving: Using Autoethnography And Narrative Inquiry To Indigenize Sense Of Belonging In Higher Education, Devon S. Isaacs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Native American students in higher education are often asked to find a sense of belonging in places and spaces that do not reflect their cultures or worldviews. This can lead to isolation and a feeling of having to choose between themselves and their identities as Indigenous peoples. This contributes to poorer mental health, loss of well-being, and decreased academic success. The purpose of this study was to ask seven Native American participants how they defined sense of belonging from their own worldviews. Participants were also asked about spaces and places in higher education that helped or did not help them …

Assessing Socio-Demographic And Urban Form Changes Of Sprawl Retrofitting Projects In The United States, Hooman Hadayeghi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Growing population and urbanization have escalated the inclination in today’s societies to live in the suburbs. In the United States, urban development has had a suburbanization pattern since World War II. People living in such areas must use their cars to reach their destination and commute to work. Sprawl retrofitting is a term introduced by planners and researchers to overcome urban sprawl's negative impacts on mobility, transportation, and the environment. This approach is used to densify and change the built environment to make daily trips easier, shorten daily travels, and enhance pedestrian activity in places dealing with sprawl. Sprawl retrofitting …

Validation And Exploration Of The Multidimensional Psychological Flexibility Inventory With A Sample Of Adolescents, John Barr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The current study attempted to further psychological flexibility literature by validating the Multidimensional Psychological Flexibility Inventory (MPFI) with a sample of adolescents (ages 16 and 17). This analysis also examined how the MPFI associates with other indicators of psychological flexibility, distress (depression, anxiety, somatic symptom severity and related distress, difficulties in emotion regulation) and well-being (subjective happiness, life satisfaction, self-compassion, emotional approach coping).

Results from this study suggested that psychological inflexibility as measured by the MPFI positively associated with a number of measures of distress, but generally did not inversely correlate with measures of well-being in a theoretically-consistent manner, which …

Preference Reversals In Delay Of Gratification, Jeremy M. Haynes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Intertemporal choices are decisions between outcomes occurring at different times. For example, people may choose to quit smoking cigarettes for the delayed health-related benefits associated with abstention, or they may continue to smoke for the immediate gratification associated with smoking now. Importantly, patterns of intertemporal choices among people are associated with a number of maladaptive behaviors (e.g., cigarette smoking). In the present set of studies, I examine a facet of intertemporal choice: preference reversals. Although there are multiple forms of preference reversal, I focus on those characterized by shifts in preference from a larger-later reward to a smaller-immediate reward after …

A Comparison Of The Effects Of Varied Verbal Prompts Paired With Visual Prompts On Echoic Verbal Behavior With Minimally Verbal Students, Chelsea Nielsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous research conducted by Valentino, Shillingsburg, Conine and Powell (2012) has recommended that practitioners do not utilize the word “say” before or in an instruction to reduce the word “say” being echoed. The current study sought to extend previous research by including the word “say” and comparing it with the condition of not using the word “say”. Components compared included how frequently responses occurred and how long it took for a response to occur. Two participants were included in the study, but only one participant completed the study. Findings agreed with the recommendation made by Valentino, Shillingsburg, Conine and Powell …

Normative Evaluations Of Resource Conditions: The Influence Of Visitor Characteristics And Implications For Recreation Management In Urban-Proximate Parks, Jordan E. Nesbitt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Urban-proximate parks and protected areas provide a unique recreation landscape to individuals living in and near urban centers. They have been shown to provide similar recreation experiences to traditionally studied parks and protected areas such as National Parks, National Forests and Wilderness areas. This study takes place in a set of four urban-proximate parks in Orange County, California, USA. These parks are designated as urban-proximate because they are located within 100 miles of an urban center with 1 million or more people. Using norm theory, a well vetted social science theory, this work sought to identify thresholds of acceptability for …
