Mindfulness And Observational Drawing, Corinne Christopherson Sonderegger Apr 2022

Mindfulness And Observational Drawing, Corinne Christopherson Sonderegger

Theses and Dissertations

Observational drawing has many benefits, yet it can be a difficult and frustrating curriculum for students and teachers alike. As I was teaching elementary and college art classes simultaneously, I noticed a significant discrepancy between my younger and older students. Students in my elementary art classes loved to draw and often expressed how excited they were to make art. However, students in my college art classes were more hesitant and self-conscious about drawing and did not believe they could progress artistically. Many of these students had abandoned drawing in elementary or middle school. This pattern evokes the U curve of …


A Survey-Based Analysis On Adult Community Esl Learners: Perceptions Of Challenges, Online Learning, Resources, And Skills, Adriana Reeve Apr 2022

A Survey-Based Analysis On Adult Community Esl Learners: Perceptions Of Challenges, Online Learning, Resources, And Skills, Adriana Reeve

Theses and Dissertations

"One thing cannot be disputed: immigrants from all backgrounds and levels of cultural capital are drawn to noncredit ESL programs with high hopes of a brighter future and the attainment of the American dream" (Becker 2011). Adult ESL community learners are a fast-growing and diverse group of individuals. Previous studies demonstrate the many challenges this group faces in attending English classes (Tan, Nabb, Aagard, and Kim 2010; Tucker 2007) and the need for more online learning to better meet their needs (Eyring 2014; Reynard 2003). A survey was administered to 136 adult community ESL learners enrolled at the Provo, Utah …


Defining And Evaluating Design Patterns To Increase "This Is Not A Game" (Tinag), Lucia A. Mata Apr 2022

Defining And Evaluating Design Patterns To Increase "This Is Not A Game" (Tinag), Lucia A. Mata

Theses and Dissertations

TINAG, which stands for This is Not a Game, can be defined as "the concept that there are pervasive games, often ARGs, that are designed to immerse players in such a way that they suspend their disbelief in a fictional narrative and act like the world they have entered is real during their play time" (Pohjola 2004). Many designers and educators want to create games that appear real, but they are unsure of how to accomplish this. Increasing TINAG allows designers to create more realistic games while taking advantage of the many benefits that TINAG experiences offer. The purpose of …


Principles Of Coaching For Coaching Of Principals: A Self-Directed Approach, Suzanne M. Kimball Apr 2022

Principles Of Coaching For Coaching Of Principals: A Self-Directed Approach, Suzanne M. Kimball

Theses and Dissertations

Research on school districts has repeatedly found that focusing on student learning and instructional leadership is a key component to effectiveness (Murphy & Hallinger, 1988; Leithwood, 2010; Anderson & Young, 2018). Districts are currently undergoing a redefinition of roles in order to specifically support principals as instructional leaders in their schools. This qualitative case study describes how one district began to develop a system for supporting principals through incorporating leadership coaching. This study shares the perspectives of principal supervisors and other district specialists as they built their own capacities to be effective coaches. The complexity of simultaneously developing skills in …


Accurate Band Energies Of Metals With Quadratic Integration, Jeremy John Jorgensen Apr 2022

Accurate Band Energies Of Metals With Quadratic Integration, Jeremy John Jorgensen

Theses and Dissertations

Materials play an important role in society. Historically, and even at present, materials have been discovered by trial and error, and many of the most useful materials have been discovered by chance. The high-throughput approach aims to remove (as much as possible) chance and guesswork at the experimental level by filtering out materials candidates that are not predicted to exist. Many successes have been recorded. In the high-throughput approach to materials discovery, machined-learned models of materials are created from databases of theoretical materials. These databases are the result of millions of density-functional-theory (DFT) simulations. The size and accuracy of the …


The Role Of Bacterial Genotype In The Persistence Of The Microbiota Of Drosophila Melanogaster, Sarah J. Gottfredson Apr 2022

The Role Of Bacterial Genotype In The Persistence Of The Microbiota Of Drosophila Melanogaster, Sarah J. Gottfredson

Theses and Dissertations

In this work we use the fruit fly Drosophila melanogaster as a model to identify bacterial genes that help bacteria to persist in their animal hosts. Early work on this model system established that dietary replenishment drives the composition of the D. melanogaster gut microbiota, and subsequent research has shown that some bacterial strains can colonize the fly for much longer than the flow of bulk diet through the gut. In this work we reveal that bacterial genes influence bacterial persistence by studying the correlation between bacterial genotype and persistence in the D. melanogaster gut microbiota. We performed an initial …


How Failures Cascade In Software Systems, Barbara W. Chamberlin Apr 2022

How Failures Cascade In Software Systems, Barbara W. Chamberlin

Theses and Dissertations

Cascading failures involve a failure in one system component that triggers failures in successive system components, potentially leading to system wide failures. While frequently used fault tolerant techniques can reduce the severity and the frequency of such failures, they continue to occur in practice. To better understand how failures cascade, we have conducted a qualitative analysis of 55 cascading failures, described in 26 publicly available incident reports. Through this analysis we have identified 16 types of cascading mechanisms (organized into eight categories) that capture the nature of the system interactions that contribute to cascading failures. We also discuss three themes …


Playable Case Study Content Management System, Mitchell Stevenson Cross Apr 2022

Playable Case Study Content Management System, Mitchell Stevenson Cross

Theses and Dissertations

Educational simulations can help mitigate the natural gap between traditional education styles and the current professional world. Researchers at BYU have developed an educational simulation solution called Playable Case Studies (PCSs). PCSs are simulations that expose the user to real world scenarios and problems within a pre-built environment. With rising demand and use of these educational simulations, there is a need for easy and inexpensive ways to develop these simulations or Playable Case Studies (PCSs). We propose a content management system (CMS) that is tied to a system that utilizes dynamic modules that make up these simulations. We present a …


Student Perspectives On Feedback In A Spanish Medical Interpreting Course, Allison Rebecca Brimhall Apr 2022

Student Perspectives On Feedback In A Spanish Medical Interpreting Course, Allison Rebecca Brimhall

Theses and Dissertations

Medical interpreter education is a fast-growing field in which learners sometimes receive inadequate feedback to help them improve their interpreting skills (Sultanić, 2021). This qualitative study focused on students’ perspectives on the different types of feedback given in a university Spanish medical interpreting course. Interviews and written reflections were analyzed to investigate what students personally considered to be the outcomes of the class and how feedback given in the course was associated with their development of interpreting skills and self-efficacy. Students reported that they found the most meaningful improvement through (1) guided self-assessment to discover gaps in their abilities, (2) …


Parental Incarceration As A Predictor Of Legal Cynicism, Mackenzie Joy Heim Apr 2022

Parental Incarceration As A Predictor Of Legal Cynicism, Mackenzie Joy Heim

Theses and Dissertations

Researchers have established that legal cynicism is linked to violence, deviant behavior, and crime. In response to the potentially dangerous implications of a legally cynical society, research in recent years has attempted to identify experiences and conditions that play a role in the development of legal attitudes. Given that youths' familial and social conditions appear to be influential predictors, this study tests the relationship between parental incarceration and legal cynicism. Data from the Fragile Families and Child Wellbeing Study were used for this analysis. Results from three OLS regression models indicate that parental incarceration is not a significant predictor of …


The Perception Of At-Risk Students On Caring Student-Teacher Relationships And Its Impact On Their Productive Disposition, Brittany Hopper Apr 2022

The Perception Of At-Risk Students On Caring Student-Teacher Relationships And Its Impact On Their Productive Disposition, Brittany Hopper

Theses and Dissertations

The importance of a positive, caring relationship with students in the classroom is under-researched in mathematics education. Research shows that a positive student-teacher relationship can have many long-term positive results for the student. Many of these results directly impact a student's productive disposition towards mathematics. At-risk students are in greater need of positive relationships and an increase in productive disposition. Using Joan Tronto's (1993) elements of care, I examine the student perspective of these kinds of relationships and how the student sees development of their own productive disposition.


A Permutation-Based Confidence Distribution For Rare-Event Meta-Analysis, Travis Andersen Apr 2022

A Permutation-Based Confidence Distribution For Rare-Event Meta-Analysis, Travis Andersen

Theses and Dissertations

Confidence distributions (CDs), which provide evidence across all levels of significance, are receiving increasing attention, especially in meta-analysis. Meta-analyses allow independent study results to be combined to produce one overall conclusion and are particularly useful in public health and medicine. For studies with binary outcomes that are rare, many traditional meta-analysis methods often fail (Sutton et al. 2002; Efthimiou 2018; Liu et al. 2018; Liu 2019; Hunter and Schmidt 2000; Kontopantelis et al. 2013). Zabriskie et al. (2021b) develop a permutation-based method to analyze such data when study treatment effects vary beyond what is expected by chance. In this work, …


Biophysical Factors Control Invasive Grass Hot Spots In The Mojave Desert, Tanner Corless Smith Apr 2022

Biophysical Factors Control Invasive Grass Hot Spots In The Mojave Desert, Tanner Corless Smith

Theses and Dissertations

The social, economic, and ecological costs of plant invasions are vast, through their ability to alter ecosystem structure and function. Invasive annual grasses are a nuisance in the American Southwest through promotion of the grass-fire cycle. Annual grasses such as Bromus rubens, Bromus tectorum, Schismus barbatus, and Schismus arabicus have invaded the Mojave Desert and increased fire occurrence, thus it is important to identify and characterize the areas where persistent invasion has occurred and subsequently fire risk is increased by understanding the distribution of these invasive grasses. Previous plot and landscape-scale research has revealed anthropogenic and biophysical correlates with the …


Using Movement To Infer Critical Life History Events In Mule Deer: Parturition And Natal Dispersal, Tabitha A. Hughes Apr 2022

Using Movement To Infer Critical Life History Events In Mule Deer: Parturition And Natal Dispersal, Tabitha A. Hughes

Theses and Dissertations

The advent of GPS tracking technology has revolutionized the field of wildlife research. The ability to obtain fine-scale location data from collared animals allows for increased understanding of life-history events that have previously been difficult to research. An excellent candidate species for telemetry-based research is mule deer (Odocoileus hemionus). Mule deer are an important species economically due to their position as a harvested species. Additionally, they play an important role in the ecosystems they occupy; therefore information regarding important life history events would improve conservation and management efforts for this species. Our objectives were to use GPS tracking technology to …


A New Approach For 3d Printed Microfluidic Device Design Based On Pre-Defined Components, Cassandra Ester Slaugh Apr 2022

A New Approach For 3d Printed Microfluidic Device Design Based On Pre-Defined Components, Cassandra Ester Slaugh

Theses and Dissertations

3D printing for microfluidic device fabrication has received considerable interest in recent years, in part driven by the potential to dramatically speed up device development by reducing device fabrication time to the minutes timescale. Moreover, in contrast to traditional cleanroom-based fabrication processes that require manual production and stacking of a limited number of layers, 3D printing allows full use of the 3D fabrication volume to lay out microfluidic elements with complex yet compact 3D geometries. The Nordin group has successfully developed multiple generations of high resolution printers and materials for microfluidic devices that achieve this vision. However, because of the …


Inhibition Of Cell Adhesion And Actin Localization During Migration Upon Protective Antigen Mutant Ligand Binding To The Capillary Morphogenesis Gene 2, Sai Lun Lee Apr 2022

Inhibition Of Cell Adhesion And Actin Localization During Migration Upon Protective Antigen Mutant Ligand Binding To The Capillary Morphogenesis Gene 2, Sai Lun Lee

Theses and Dissertations

Capillary Morphogenesis Gene 2 protein (CMG2) is a type 1 transmembrane receptor known as the anthrax toxin receptor 2 (ANTXR2). While it is documented that the cell surface receptor CMG2 mediates anthrax toxin entry into the cell via endocytosis, the physiological role of CMG2 is not well understood. Others have suggested that CMG2 may have a role in mediating ECM homeostasis and angiogenesis. Additionally, both anthrax protective antigen (PA) and a furin protease-resistant mutant, PASSSR, inhibit corneal neovascularization in a mouse model, and interestingly PASSSR has a greater affinity to CMG2 receptor. PASSSRalso has a more potent antiangiogenic effect than …


Settler-Author Allyship In Centering Indigenous Ecologies: Communal Will Through Collective Environmental Guilt In This Tender Land And Caleb's Crossing, Elena Marie Arana Apr 2022

Settler-Author Allyship In Centering Indigenous Ecologies: Communal Will Through Collective Environmental Guilt In This Tender Land And Caleb's Crossing, Elena Marie Arana

Theses and Dissertations

The January 2021 edition of PMLA housed an entire cluster on "Indigenous Literatures and the Anthropocene," in which at least four of the eight non-Indigenous contributors directly addressed and supported a call for learning from and collaborating with Indigenous voices. The unanimity of the discussion dissolves somewhat drastically when considering exactly how this should be done, leading Melanie Taylor to voice one of the framing questions of the cluster: "If it is increasingly clear that not all members of Anthropos are equal drivers of the Anthropocene, and that not all are uniformly compromised by its havoc, how can we begin …

Theses and Dissertations

This thesis project proposed the building of a website as a repository of authentic texts in video format for teaching foreign or second languages. The project planned the building of a minimal viable product or MVP with authentic videos both in English and Spanish, organized by the ACTFL levels with particular attention to the Intermediate level. Data were collected from a survey of 42 respondents in the United States and 89 combined from Spain and Mexico. The responses collected suggest that there is a need for this MVP. Additionally, the data indicated which features were most wanted by these teachers. …


Returning Thanks To God And Others: The Relational, Prosocial, And Emotional Consequences Of Transcendent Indebtedness, Jenae Marie Nelson Apr 2022

Returning Thanks To God And Others: The Relational, Prosocial, And Emotional Consequences Of Transcendent Indebtedness, Jenae Marie Nelson

Theses and Dissertations

Gratitude and indebtedness facilitate cooperative relationships and altruism. Although most of the world endorses some belief in God, gratitude and indebtedness to God have not received adequate empirical attention. The "Gratitude to God" research initiative was created to address this gap, of which the current project is an appendage. This project encapsulates a multiphase research proposal, including three parts; a pilot study and two experimental studies. The purpose of the pilot study (N = 475) was to create and test experimental manipulations for the two experimental studies. Experiment 1 (N = 659; highly religious emerging adult sample) was a 3x2 …


Monitoring Of Foraging Sites For Ungulates Within Alpine Plant Communities And Establishment Of Long-Term Monitoring Plots For Rare Castilleja Parvula Var. Parvula In The Tushar Mountains, Utah, Heather Shipp Apr 2022

Monitoring Of Foraging Sites For Ungulates Within Alpine Plant Communities And Establishment Of Long-Term Monitoring Plots For Rare Castilleja Parvula Var. Parvula In The Tushar Mountains, Utah, Heather Shipp

Theses and Dissertations

The Tushar Mountains of Utah provide essential alpine habitat to a variety of flora and fauna, including 27 endemic plant species and several ungulates (mountain goats, deer, elk, cattle). These ungulates were observed throughout two growing seasons and field analyses were conducted to assess foraging selection. Overall, most ungulates, especially large nursery herds, tended to prefer foraging amongst alpine regions within the Bullion volcanic of the Tushars, which is characterized by denser vegetation than the Belknap volcanic region. Mountain goats and deer were most frequently observed foraging within the Tushar alpine habitat; however, elk and domestic cattle were also observed. …

Positive Psychology Interventions In An Sla Context: A Semester-Long Study Of The Impact Of Positive Psychology On The Well-Being And Language Development Of English Language Learners, Carolee Rogers

Theses and Dissertations

This article reports on a study investigating the effectiveness of positive psychology interventions (PPIs) in an Intensive English Program (IEP) for non-matriculated university students. Interventions based on the PERMA model for wellbeing (positive emotion, engagement, relationships, meaning, and accomplishment) were implemented through weekly 65-minute lessons and short daily activities. Each lesson introduced an aspect of the PERMA model such as positive emotion or achievement. Along with this focused instruction, students concurrently engaged in language learning activities. Teachers also provided short daily activities for reinforcement throughout the week. Six classes received these interventions, while three classes served as a control group …


Explicit Instruction In Second Language Self-Assessment: Exploring The Potential For Improving Calibration Through Training, Rachael Reynolds Apr 2022

Explicit Instruction In Second Language Self-Assessment: Exploring The Potential For Improving Calibration Through Training, Rachael Reynolds

Theses and Dissertations

This study explores the effect of an explicit training module on improving language learner ability to accurately self-assess second-language proficiency. There was a total of 409 intermediate and advanced level participants across six languages: French, Italian, Japanese, Portuguese, Russian and Spanish. Most of the participants had extensive immersion backgrounds. The Language Ability Self Evaluation Resource (LASER) was used to measure the perceived proficiency of the participants (self-assessed language ability). The Oral Proficiency Interview – Computer (OPIc) was used to measure the actual proficiency of the participants (rater-assessed language ability). The participants were randomly assigned to either the control or experimental …


Physical Place And Online Space: Permeability, Embodiment, And Gender In Two Online, Synchronous Critical Multicultural Teacher Education Courses, Elizabeth Finlayson Harris Apr 2022

Physical Place And Online Space: Permeability, Embodiment, And Gender In Two Online, Synchronous Critical Multicultural Teacher Education Courses, Elizabeth Finlayson Harris

Theses and Dissertations

This semester-long microethnography explores how the emotional geography in two online, synchronous critical multicultural education courses are shaped by online interactions and infrastructures as well as social frames. Using a microethnographic approach, video data, interviews, and open-ended questionnaires revealed patterns of interactions suggesting an online emotional geography characterized by a duality of physical place and online space. Key findings suggest that the levels of permeability in student and instructor's physical location influence how online participants gave or received emotion gifts and performances in online spaces. This study further supports emergent research suggesting gender frames as relevant in students' level of …


“If I Could Do This, I Feel Anyone Could:” The Design And Evaluation Of A Two-Factor Authentication Manager, Garrett D. Smith Apr 2022

“If I Could Do This, I Feel Anyone Could:” The Design And Evaluation Of A Two-Factor Authentication Manager, Garrett D. Smith

Theses and Dissertations

Two-factor authentication (2FA) is a strong defense against account compromise. However, usability studies reveal challenges with 2FA setup. The process to manually setup and remove 2FA methods differs across websites. We present a system design for a 2FA manager to automatically setup and remove 2FA methods. Potential benefits are reduced time, fewer mistakes, consistent terminology, a single workflow for users to learn, and the ability to rapidly transition to a new 2FA method—e.g., when replacing a lost 2FA method. We create two proof-of-concept implementations of our design, one as a browser extension and one integrated as a feature in an …


Using Connections To Make Predictions On Dynamic Networks, Rebecca Dorff Jones Apr 2022

Using Connections To Make Predictions On Dynamic Networks, Rebecca Dorff Jones

Theses and Dissertations

Networks are sets of objects that are connected in some way and appear abundantly in nature, sociology, and technology. For many centuries, network theory focused on static networks, which are networks that do not change. However, since all networks transform over time, static networks have limited applications. By comparison, dynamic networks model how connections between objects change over time. In this work, we will explore how connections in dynamic networks change and how we can leverage these changes to make predictions about future iterations of networks. We will do this by first considering the link prediction problem, using either Katz …


Parental Perceptions Of Elementary Aged Children Learning To Code, David Daniel Apr 2022

Parental Perceptions Of Elementary Aged Children Learning To Code, David Daniel

Theses and Dissertations

Little research has been conducted to understand the role that parents play in children learning to code even though coding has become a necessary skill for students to successfully study STEM (Science, Technology, Engineering, Math) subjects. After identifying five factors that would influence parental perceptions, we developed a survey and administered it to parents of elementary aged children. We validated the survey using a confirmatory factor analysis and structural equation modeling. To be considered valid, factors needed to meet three of the following four fit statistics: RSMEA < 0.08, SRMR < 0.08, CFI > 0.9, TLI > 0.9. Items needed to have a factor loading > 0.3 with a …


Implementation Of A Genome-Wide Survey Of Induced Mutations To Identify Agronomically Valuable Variants In Chenopodium Quinoa, Andrew Alarcon Parker Apr 2022

Implementation Of A Genome-Wide Survey Of Induced Mutations To Identify Agronomically Valuable Variants In Chenopodium Quinoa, Andrew Alarcon Parker

Theses and Dissertations

Quinoa has been utilized for millennia in the Andes region of South America as a nutritious and hardy food crop. In recent years interest in quinoa has grown as need increases for an alternative to traditional cereal crops that can tolerate marginal environments while offering superior nutrition. Growers outside the Andes have experienced several complications adopting quinoa, including undesirable secondary metabolites, poor yield, lodging, and height inconsistency. Unfortunately, access to native ecotypes for crop improvement is limited, and desirable traits are difficult to introduce into available quinoa cultivars because of its allotetraploid genome and tendency to self-pollinate. A genome-wide survey …


Systems Engineering Of The Global L-Band Observatory For Water Cycle Studies, James Nathan Smith Apr 2022

Systems Engineering Of The Global L-Band Observatory For Water Cycle Studies, James Nathan Smith

Theses and Dissertations

The Global L-band Observatory for Water Cycle Studies (GLOWS) is designed as a follow-on to the Soil Moisture Active Passive (SMAP) observatory launched in 2015. While GLOWS is essentially copying many aspects of the SMAP mission, a key change has been made in the antenna technology. SMAP uses a reflector antenna and to reduce mission costs GLOWS uses a metamaterial lens antenna. This type of antenna is less efficient, so it must be proven that GLOWS can achieve the same uncertainty levels in soil moisture measurements as SMAP. In this work, a unified framework for modeling and analyzing GLOWS' ability …

Critical Incidents In Sustaining A Behavior Management Level System With Special Education Students In A Self-Contained School, Stephanie Johnson

Theses and Dissertations

Level systems provide systematic support for teachers and students who need additional behavior support. The purpose of this study was to evaluate the perspectives of faculty members from a self-contained school, for special education students with severe behavior needs, which has sustained the use of a school-wide, behavior management level system for nearly 30 years. A total of 11 faculty members were interviewed using the critical incident technique, a qualitative methodology used as an exploratory tool in early stages of research. Interviews detailed the observable behaviors and specific events, critical incidents, that helped or hindered the sustainability of their school's …


Aiding Semantic Memory Creation With Navigational Context, Thomas Benjamin Lyle Wasden Apr 2022

Aiding Semantic Memory Creation With Navigational Context, Thomas Benjamin Lyle Wasden

Theses and Dissertations

While we have traditionally understood the hippocampus to be involved in memory and navigation, it also appears that it has a role in language processing, creation and prediction. An obvious explanation for this is that language is impossible if linguistic signs cannot be remembered and retrieved. Because linguistic signs are definitionally biologically neutral or arbitrary, we must use the brain's apparatus for learning and storing information from the external world to store and retrieve them. Although plausible, this explanation fails to take into account the hippocampus' role in navigation as a contributing element in the processing, storage and retrieval of …
