High School Biology Teachers' Integration Of Argumention In The Context Of Disciplinary Literacy Coaching, Ashley Strong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Scientific argumentation is a core scientific practice. Although scientific argumentation has been linked to increased learning of scientific content, improved reading, writing, and critical thinking, traditional science classrooms have not included scientific argumentation. Teachers often have little experience learning or teaching science through argumentation and need support to integrate this complex practice of science into their classrooms. This study compared four high school biology teachers’ instruction of scientific argumentation as they worked with a literacy coach. Data were collected through interviews, audio recordings of classroom instruction and literacy coaching sessions, and artifacts. After analyzing the data, several key findings stood …

Cultural, Contextual, And Individual Determinants Of Mental Health Service Utilization Among Latinx Emerging Adults, Kenia Carrera Diaz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Despite being at an increased risk of experiencing mental health problems, Latinx emerging adults underutilize professional psychological services compared to other ethnic/racial groups. It is important for researchers to understand this mental health disparity to improve Latinx emerging adults’ use of quality mental health services (MHS). The current project investigated factors that might influence Latinx emerging adult’s use of MHS through two separate studies. In the first study, I systematically reviewed research published in the past decade that examined predictors of MHS use among Latinx emerging adults. A total of 9 studies were found and included in this review. This …

Control Mapping Methodology For Tailless Morphing-Wing Aircraft, Zachary S. Montgomery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Advanced aircraft designs tend to have several control surfaces or devices that affect the flight of the aircraft. It is difficult or even impossible for a pilot to directly control each of these devices and fly the aircraft well. Therefore, a control mapping logic is needed to take typical pilot commands and map them to what the control devices should do to achieve the pilot’s commands. This work presents a methodology for determining this control mapping logic using two different approaches. The first uses a theoretical approach based on lifting-line theory, while the second leverages computational methods. The methodology consists …

An Examination Of The Golden Ratio In General Education Classrooms, Carrie Mclaughlin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A large body of research indicates use of praise as a response to appropriate behavior is an effective classroom management strategy to increase appropriate behavior and decrease problem behavior. Since prior research also suggested that teachers tend to have more negative interactions with students than positive ones, use of a specific praise to reprimand ratio is commonly recommended in teacher preparation programs and professional development. However, recommendations regarding the optimal ratio vary and there is limited evidence to support use of any specific ratio. There have also been relatively few studies examining naturally occurring rates of teacher praise, reprimands, and …

Management Of Garlic Mustard (Alliaria Petiolata), Sahara Mustard (Brassica Tournefortii), And Elongated Mustard (Brassica Elongata) In Utah, Natalie Layne Fronk

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The invasive mustard species Sahara mustard (Brassica tournefortii), garlic mustard (Alliaria petiolata) and elongated mustard (Brassica elongata) negatively impact a variety of ecological systems across the state of Utah. The distribution of these species in Utah is relatively limited at the current time. If prompt action is taken, it may be possible to contain and manage these species before irreparable ecological and agricultural damage occurs. For this reason, all three mustards are listed by the State of Utah as weeds of high priority for management.

This project tested multiple strategies to determine effective species-specific …

The Association Of Military Sexual Harassment/Assault With Suicidal Ideation, Plans, Attempts, And Mortality Among Service Members And Veterans: A Meta-Analysis And Research Study, Whitney S. Livingston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rates of death by suicide and sexual harassment/assault that occurs during military service (MSH/A) are higher among service members/veterans than rates of suicide and sexual violence among civilians. Suicide risk includes thoughts and attempts, and research examining the strength of the relationship between suicide risk and sexual violence across past studies that examined this association are limited to civilians. Moreover, current theories hypothesizing which factors are related to suicide risk do not adequately predict suicide among service members and veterans, and do not account for factors such as MSH/A. This two-study dissertation first calculated the magnitude of the relationship between …

Novel Patterning Techniques To Improve Digital Image Correlation In Challenging Environments, Weston Craig

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A camera-based measurement technique called digital image correlation (DIC) is beneficial to measure displacement and strain in challenging environments (such as post-irradiation evaluation and high temperature environments) due to its non-contacting nature and ability to obtain measurements over multiple length scales. This technique requires a surface pattern which influences the measurement resolution and accuracy of the measurements. This thesis explores two novel patterning techniques to allow the use of DIC in more challenging environments:

The first is to determine if a pattern created from printed text can be used as a pattern in DIC. Native patterns are patterns already present …

Quantification Of Hydrologic Response To Forest Disturbance In Western U.S. Watersheds, Sara A. Goeking

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Forested watersheds produce more than half of the water supply in the United States. Forests affect how precipitation is partitioned into available water versus evapotranspiration. This dissertation investigated how water yield and snowpack responded to forest disturbance following recent disturbances in western U.S. forests during the period 2000-2019.

Chapter 2 systematically reviewed 78 recent studies that examined how water yield or snowpack changed after forest disturbances. Water yield and snowpack often increased after disturbance, but decreased in some circumstances. Decreased water yield was most likely to occur following disturbances that did not remove the entire forest canopy. It was also …

Dairy Breed, Grass-Birdsfoot Trefoil Mixture, And Pasture Nutrition Effects On Intake, Feed Efficiency, And Grazing Adaptation, Michael Greenland

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dairy cattle have lower dry matter intake (DMI) on pastures thus leading to less weight gain and milk production than feedlot cows. This study was conducted to determine whether different dairy breeds are better adapted to lower or higher quality pastures as measured in DMI and feed efficiency. The eight treatments consisted of Jersey, Holstein, Holstein-Jersey crossbreds, and 3-breed crossbreds (Montbéliarde-Swedish Red-Holstein) heifers on grass monocultures and grass-BFT mixtures. We observed greater DMI on grass-BFT mixtures. Among breeds, Holstein had the greatest DMI, then the two crossbreds, and Jersey had the least. Feed efficiency was most favorable for Jersey, less …

Syntactic Complexity In Reading Comprehension: An Eye-Tracking Study Of Text Processing Among Bilinguals And Monolinguals, Guoqin Ding

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For Chinese students, studying in a country with different cultural components and language structures is challenging. Compared to English, the Chinese prefers shorter and simple sentence structure and allows for two sentences to be stated side by side. Different sentence structures in Chinese may influence native-Chinese readers’ understanding of English sentences and even a whole text. This exploratory study examined whether there were any differences between English monolingual and Chinese-English children while reading varied English texts with simple or complex structures at different reading difficulty levels. This study explored the differences across texts and readers, as well as the possible …

Who Is More Likely To Be Delinquent In Their Mortgage Payments Among Homeowners? The Role Of Financial Literacy, Ellie Donne Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Homeownership is a way for families to build wealth and marks status attainment. Despite the many benefits of homeownership, homeowners who are delinquent on their mortgages lose the effective means of wealth accumulation and may trigger the beginning of the foreclosure process. There is evidence that homeowners with appropriate levels of financial literacy have a lower likelihood of mortgage delinquency.

Using data from the 2018 National Financial Capability Study (NFCS), the main purpose of this study was to examine what factors are associated with mortgage delinquency among homeowners. This study also examined to what extent financial literacy plays a role …

High-Isolation Antenna Technique For Cubesat-Borne, Continuous-Waveform Radar, Logan E. Voigt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Radar is important in target tracking, imaging, and weather prediction applications. As technology is increasingly miniaturized, there is a push for smaller radar. Research and exploration in outer space also benefit from small, low-power technologies. The NASA Jet Propulsion Laboratory’s RainCube was the first successful CubeSat-borne radar. A CubeSat is a type of small satellite that conforms to specific size and weight standards. Radar technology benefits from additional research on how to further miniaturize radar payloads.

Integrating the transmit and receive antennas on the solar panels removes the need for antenna-deployment mechanisms, preserving space on the CubeSat. This thesis also …

Teaching Multicultural Psychology As A Cultural Competence Intervention: An Empirical Evaluation Of Course Components, Elizabeth Tish Hicks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous research has shown that a semester-long multicultural psychology course can effectively increase students’ cultural competence-related attitudes when students complete the class in-person and online. Cultural competence refers to the knowledge, awareness, and skills required to appreciate, recognize, and effectively work with members of other cultural groups. This dissertation examined several components of a multicultural psychology course: ethical grading, skill development, and intergroup contact. The first paper discussed techniques used to minimize grading bias and examined whether cultural competence shifts impacted grading. Students’ cultural competence scores did not relate to or predict their grades in the course, which supported the …

School Resource Officers' Reports Of Training And Perceptions Of High School Students With Disabilities, Kandace T. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this explanatory sequential, mixed methods research study was to identify the perceptions of school resource officers (SROs) regarding high school students with disabilities and their preparedness to work with this population, as a result of their SRO training. This study involved a national quantitative survey of SROs working in public high schools, followed by one-on-one interviews from the same sample to allow for a deeper analysis of the survey results and develop a theory on how training impacts SRO preparedness and their perceptions of high school students with disabilities. The resulting theory ascertained that the presence of …

Collaborative Practices Of Rural Inclusive Postsecondary Education Program (Ipse) Directors, Elizabeth Susanne Goode Dimond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Inclusive postsecondary education programs (IPSE) for students with intellectual disabilities (ID) are relatively new, having their formal beginning in the Higher Education Opportunity Act (HEOA; P.L. 110-315) of 2008. These programs vary greatly and are found in urban, suburban, and rural areas of the United States. Those programs in rural areas face unique barriers and have unique strengths that affect how they collaborate and with whom they collaborate. The purpose of this qualitative phenomenological study is to describe the collaborative practices of rural IPSE program directors. This study gathered the lived experiences of rural IPSE program directors collaborating with agencies …

Empirical Evaluation Of Route-Based Landscape Experiences, Garet Openshaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis explores a method of visual analysis that aims to create a more in-depth understanding of how individuals see and visually perceive their environment. Here we explore a geospatial tool, called Visual Magnitude, to assess road-based experiences. We aimed to provide evidence of a relationship between the tool and scenic rating preferences from a survey. The content of this thesis is split between two articles. The first article, contained in Chapter 2, focuses on optimizing the selection of viewpoints along route-based envrionments. In this study we ask the question is there an optimal sampling rate of viewpoints along a …

Relationships Between Middle School Students' Adaptive Reasoning When Creating Learner-Generated Drawings And Partner Talk During Inquiry-Based Mathematical Tasks, Angela M. Frabasilio

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adaptive reasoning is one of five components students use to develop mathematical expertise and become mathematically proficient. When students adapt their reasoning they are logically thinking about the mathematical relationships between concepts and adapting their thinking to solve problems. Three Act Math Tasks are popular math problems used in schools in which students engage in adaptive reasoning. These types of problems are beneficial to students because they engage students in inquiry-based learning, a kind of learning where students work to pose questions, interpret data, design ways to solve the problem and present their solutions. Little is known about how students …

Toward A Conceptual Approach To The Coriolis Force: Cataloging Intuitive Knowledge Elements In Intermediate Physics Learners, Jared B. Arnell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In Physics, the topic of the Coriolis force is often confusing and difficult to teach. I conducted a series of interviews with undergraduate physics students to understand how they would use their prior knowledge and personal experiences to interact with and navigate through a new conceptual teaching approach for the Coriolis force. Many students applied their intuitive understanding of balance to interpret and make predictions about the Coriolis force. Some students displayed a strong conviction that rotating objects will naturally get pulled outward, which suggests that this impression may be a useful tool for novice physics learners to use in …

Developing Confidence And Interest In Teaching Relevant Mathematical Modeling Lessons, Jacy Beck

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

What is mathematical modeling and how can inservice and pre-service teachers develop the skills and competencies necessary to increase confidence and interest in teaching relevant mathematical modeling lessons? Mathematical modeling is “the process of choosing and using appropriate mathematics and statistics to analyze empirical situations, to understand them better, and to improve decisions” (CSSM, 2010, p. 72). By providing students with an opportunity to engage in relevant mathematical modeling prompts, we provide them with transferable skills and knowledge. The aim of this paper will be to provide insight into the relevance of teaching mathematical modeling, provide resources for integrating modeling …

A Moderated Mediation Model Of Gender, Posttraumatic Cognitions, And Posttraumatic Stress Disorder Symptoms After Military Sexual Assault, Hallie S. Tannahill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Military sexual assault (MSA) is associated with the greatest risk for posttraumatic stress disorder (PTSD) and PTSD severity beyond other trauma types. Sexual revictimization further increases this risk and severity. However, not all who experience MSA revictimization develop PTSD. This suggests there may be a key mechanism that explains the association between MSA and PTSD. Posttraumatic cognitions (PTC), which include an overall domain and subdomains of self, world, and self-blame, may be one such mechanism between MSA and PTSD, although this link has not yet been examined in the context of MSA revictimization. Further, literature suggests that men and women …

Urban Soil Chemical And Nutrient Management Issues Facing Emerging Small Grower Enterprises In Utah, Frank E. Oliver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Knowledge of both soil quality and contamination has become increasingly important with the growth of urban agriculture in Utah and the United States as whole. Land is also a common limiting factor in urban agriculture, so it is important to maximize yield and net returns. In order to meet these demands, three studies were conducted across key urban agriculture sites along the Wasatch Front: 1) an urban soil survey to assess soil contamination, 2) an urban soil survey to evaluate macronutrient and salinity levels, and 3) a nitrogen fertilizer management trial for dahlia (Dahlia pinnata), a cut flower …

A Dynamic Relationship With Wilderness: Comparing Day And Multi-Day Visitors' Indicators Of Quality In Wilderness Settings, Caleb Meyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The length of stay in wilderness areas is declining and, in many areas, day visitors comprise most of all use. Most prior research exploring this trend took place in the 1990s and few studies of wilderness visitation account for the increase in outdoor recreation participation over the last decade. Lack of understanding surrounding this trend raises questions about managerial and philosophical approaches to the recreation-wilderness relationship. This study explored these topics within visitor use management approaches used by the National Park Service, which manages the proposed Glen Canyon Wilderness, near Escalante, Utah, where this research took place.

Results of this …

Siblings Influence On Young Adults' Development: A Three-Study Dissertation, Jenna C. Dayley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As the longest lasting close relationship, often extending from birth until death, sibling relationships play an important role throughout the life course. To date, however, only limited work has examined the process by which siblings influence each other during young adulthood. Given that developmental differences between older and younger siblings diminish in young adulthood, it is possible that bidirectional (older-to-younger as well as younger-to-older) are more likely as compared to adolescence (in which top-down or older-to-younger influence has primarily been explored). It is further possible that processes of observational learning, including modeling, and sibling differentiation continue into young adulthood, shaping …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

World systems analysis is a historically based framework that makes looking at the world easier with trends and patterns. Using this framework and the concepts inside of it, the reader will be able to see the potential that artificial intelligence has in regard to the social, political and economic changes that will come about in the United States and China from the adoption of this technology.

Predictors Of Special Education Inequity In Rural Rocky Mountain West Schools, Jac'lyn Bera

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Current research focusing on disproportionality and equity in schools focuses on the urban environment, resulting in a significant gap in our understanding of the challenges of rural schools. For rural, racially and ethnically minoritized (R/EM) students who have disabilities, this research is largely unavailable or minimal, and negatively affects our understanding of rural needs, barriers, and successes for this historically underserved population. There is even less research focused specifically on rural students in the Rocky Mountain West (RMW) region of the United States. Understanding these factors serves as a critical area of research, and is the focus of this study. …

Sustain Water Conservation Behaviors Using Nonparametric Ranking And Social Marketing, Mahmudur Rahman Aveek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Circulation of water use feedback and conservation messaging are strategies implemented to reduce water demand on a short-term (seasonal) basis. Often considered a less impactful strategy than other tactics such as price increments and usage restrictions, authorities mostly use feedback in informational campaigns with a focus to apprise users about their water use. Such conservation programs have had limited success that has been attributed to the fact that the information provided with the feedback campaigns was generic and did not motivate users enough to sustain their water-saving behaviors. However, the advent of disaggregation technologies that can provide appliance-wise water use …

An Evaluation Of Landscape, Climate, And Management Impacts On Bumble Bees (Hymenoptera: Apidae: Bombus) In Agroecosystems, Morgan Elizabeth Christman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bumble bees play pivotal roles in pollinating wild and cultivated plant communities. Unfortunately, bumble bee populations are declining due to disturbances such as landscape conversion and climate change. Additionally, traps used to monitor pest insect populations often capture bumble bees, leading to a concern that trap captures increase bumble bee mortality. First, I studied bumble bee communities based on land cover and weather variables in agricultural fields in Utah. Bumble bee communities were more diverse in agricultural fields with more agricultural land in the surrounding area, low temperatures, and high humidity during the growing season, and less diverse in fields …

Dynamic System Discovery With Recursive Physics-Informed Neural Networks, Jarrod Mau

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis presents a novel method, recursive Physics informed neural network, to learn the right hand side of differential equations. The neural network takes in data, then trains, and then acts as a proxy for the differential equation which can be used for modeling. We show the theoretical superiority of the recursive approach. We also use computer simulations to demonstrate the proved properties.

Soil Genesis Across A Climo-Lithosequence Of Western Haleakalā, Maui, Ryan C. Hodges

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The soils of western Haleakalā are incredibly diverse due to two primary reasons: 1) they receive varying levels of rainfall based on location relative to Haleakalā, and 2) volcanic vents upwind of the area indicate that volcanic ash has blanketed much of western Haleakalā in the past. Ash can weather to form short-range-order materials, which contribute to the classification of andic soil properties. Due to their structure, short-range-order materials impart soil behavior that creates benefits and challenges in land management. Therefore, an understanding of how these soils formed and differ, and where andic soils occur is crucial.

The objectives of …

Reconstructing The Practical Theory Of Communication In Dating Matters: Examining Teen Dating Violence Prevention From A Communicative Approach, Diana Costanzo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teen Dating Violence (TDV) has lasting impacts on teens’ health and well-being. Dating Matters: Strategies to Promote Healthy Teen Relationships (DM), a curriculum published by the CDC in 2019, seeks to mitigate the consequences of TDV and promote healthy relationships. Using Grounded Practical Theory (Craig & Tracy, 1995, 2014), this paper analyzes how DM conceptualizes communication. Specifically, I explore and critique how DM discusses topics related to communication and conflict. The findings of the analysis show that DM focuses on sending the right message in communication. In DM, parents and teens are encouraged to “talk it out” or “speak up” …
