Exploring The Impact Of Collaborative Communities Among High School Principals, William T. Sherwood
Exploring The Impact Of Collaborative Communities Among High School Principals, William T. Sherwood
Theses and Dissertations
Principals of large high schools are faced with a job that is constantly increasing in demands and complexity; with few options for highly relevant professional development, good resources to aid in problem solving, and/or effective supports for social/emotional well-being. In this qualitative case study, I examine four different school districts involving 20 principals from large high schools that are involved in different iterations of collaborative communities (CC). Participants were interviewed regarding their perceptions of the benefits and challenges of the CC in which they were engaged. Participants also shared the practices and protocols present in their CC contributing to those …
Perspectives And Experiences Of Emergent Bilingual Parents Concerning Their Engagement With Their Child's Teachers And School, Jordan Foss Roberts
Perspectives And Experiences Of Emergent Bilingual Parents Concerning Their Engagement With Their Child's Teachers And School, Jordan Foss Roberts
Theses and Dissertations
Emergent bilinguals (EBs) represent the fastest-growing population in U.S. public schools (Tarasawa & Waggoner, 2015). Many EB parents face linguistic or cultural barriers when engaging with teachers and are often excluded from their children's classrooms because of their English learner status. This qualitative study analyzes EB or English learner parents' perspectives of their child's teachers and school. Critical Sociocultural Theory (C-SCT) was used to view EB parent engagement practices (Moje & Lewis, 2007). The research processes were based on Creswell and Creswell's (2018) methodology using a focus group and interview design to understand these participants' educational interactions. Data was collected …
Laying Framework For A Novel In Vitro Eukaryotic System To Measure Rate Of Transcription Elongation, John Lucas Ramirez
Laying Framework For A Novel In Vitro Eukaryotic System To Measure Rate Of Transcription Elongation, John Lucas Ramirez
Theses and Dissertations
Within each cell, genetic material is stored in the form of DNA. This DNA is compacted around proteins to form higher order structures called chromatin. The basic unit of chromatin is a histone protein octamer bound with DNA called a nucleosome. A nucleosome consists of eight core proteins, four pairs of histone proteins H2A, H2B, H3, and H4, wrapped by DNA. The DNA wraps around the histone protein roughly 1.7 times, helping facilitate the compaction of DNA within the nucleus of the cell. The location of nucleosomes makes genetic material that encodes various elements, such as promoters or enhancers, accessible …
Raising Hope: A Preliminary Investigation Of Hope-Strengthening Parenting, Anna Sellers Calley
Raising Hope: A Preliminary Investigation Of Hope-Strengthening Parenting, Anna Sellers Calley
Theses and Dissertations
Hope Theory defines hope as a cognitive-motivational process of seeking and obtaining goals through agency thinking and pathway building, with substantive connection to many desirable outcomes. While hope is theorized to begin developing early in life, this assumption has never been empirically investigated. This is due to limitations in established hope measurement. There is an additional gap in the research surrounding the role of parents in the development of hope. In this study, I address each of these gaps by utilizing a novel measure of hope in early childhood and running a multiple linear regression model to investigate potential connections …

This study focused on how early literacy practices at home affect children's language development by looking at the reading habits and dialogic book reading practices of parents with preschool-aged children. Parents were asked to consider and report on their literacy practices at home. They were asked to focus on their current reading habits with their children and how they observed their children paying attention during book-sharing sessions. This study was a part of a bigger project that developed and carried out dialogic reading workshops for parents. Preschool connections and friends spread a survey with parent-report questions in order to collect …
Cellular Sorting Of The Dictyostelium Discoideum Slug, Erin Flowerday
Cellular Sorting Of The Dictyostelium Discoideum Slug, Erin Flowerday
Theses and Dissertations
Dictyostelium discoideum (Dd) cells are amoeba cells that feed on soil or plant leaf matter bacteria. They divide freely in the presence of food. When starved, cell division is ended, and cells transition from unicellular to multicellular organisms initiated by a chemoattractant, cyclic adenosine monophosphate (cAMP). This study intricately examines cellular sorting within the Dd slug, focusing on individual cell dynamics. Represented as oriented ellipsoids, these cells maintain constant volume through a viscoelastic structure. Applying force to specific semi-axes reveals predictable deformations, highlighting the relationship between force and deformation rate. Manipulating damping coefficients and spring constants uncovers insights into cell …
Connecting Hiv-1 Viral Protein R Polymorphisms To Changes In Inflammatory Signals And Efficacy Testing Of Essential Oils As Disinfectants Against Sars-Cov-2, J. Brandon Lopez
Connecting Hiv-1 Viral Protein R Polymorphisms To Changes In Inflammatory Signals And Efficacy Testing Of Essential Oils As Disinfectants Against Sars-Cov-2, J. Brandon Lopez
Theses and Dissertations
Human Immunodeficiency Virus (HIV-1) is the causative agent for acquired immunodeficiency syndrome (AIDS). Different strains of HIV-1 have been linked to a long term non-progressor (LTNP) or rapid progressor (RP) form of disease depending on rate of AIDS progression. Viral protein R (Vpr) is a viral protein that has been linked to varying rates of AIDS progression depending on the sequence. In this work, the effects of two polymorphisms, a LTNP and a RP, on different cells are studied. The LTNP virus was linked to lower release of pro-inflammatory cytokines, such as TNF and IL-6, and an increase in apoptotic …
Development And Application Of A Particle-Based Reactor Network Model For Entrained Flow Gasifier Design, Eric Christian Monson
Development And Application Of A Particle-Based Reactor Network Model For Entrained Flow Gasifier Design, Eric Christian Monson
Theses and Dissertations
A novel particle-based reactor network model (PRNM) was developed to predict the performance of a dry-feed, pressurized, single-stage, slagging entrained flow gasifier under various operational parameters. This model provides improved detail of particle conversion as a function of gasifier location, particle size, and fuel type not available in standard reactor network models. The model inputs were designed to allow changes in geometry, firing rate, stoichiometric ratio, fuel type, and inlet gas composition. Key performance metrics included the gas and refractory temperature profiles, axial gas compositions, and particle burnout. PRNM used a network of idealized reactors to specify the flow field …
Design And Validation Of Sensing Knee Sleeve Rehabilitation Device Utilizing Large Deflection Strain Gauges, Kurt Christian Jensen
Design And Validation Of Sensing Knee Sleeve Rehabilitation Device Utilizing Large Deflection Strain Gauges, Kurt Christian Jensen
Theses and Dissertations
Total knee arthroplasty (TKA) procedures are increasingly common in the US and globally. However, rehabilitation outcomes may be negatively affected by limited access to physical therapy and patients' tendency to not fully adhere to recommended exercises between therapy sessions. This study aims to develop a remote system to aid rehabilitation, building upon recent sensor development at Brigham Young University, providing physical therapy-like biofeedback during unsupervised at-home exercises. The system developed by this research consists of three primary components: (1) a sensor array for measuring leg/knee biomechanics, (2) a machine learning algorithm to predict knee flexion angle from the sensor data, …
Chinese Mandarin-Speaking Teachers' Voices In Chinese Dual Language Immersion Programs Responding To American Classroom Management Relationship Issues, Wu-Ting Chen
Theses and Dissertations
This study examines Chinese Mandarin-speaking teachers' voices concerning classroom management (CM) in Chinese Dual-Language Immersion (DLI) classrooms in Utah, United States. Most Chinese-Mandarin-speaking teachers in Chinese DLI programs do not have a lot of experience in understanding American Western culture-style CM and therefore encounter new challenges in managing classroom behavior. Moreover, most American students, parents, teachers, and administrators do not understand the Chinese teachers' classroom expectations, nor do they realize that such behavioral expectations are a full part of learning the Chinese-Mandarin language and culture together. Using a sociocultural theoretical perspective and discourse analysis, this study provides descriptive evidence identifying …

Faculty Publications
Acoustic tweezers have gained substantial interest in biology, engineering, and materials science for their label-free, precise, contactless, and programmable manipulation of small objects. However, acoustic tweezers cannot independently manipulate multiple microparticles simultaneously. This study introduces acousto-dielectric tweezers capable of independently manipulating multiple microparticles and precise control over intercellular distances and cyclical cell pairing and separation for detailed cell-cell interaction analysis. Our acousto-dielectric tweezers leverage the competition between acoustic radiation forces, generated by standing surface acoustic waves (SAWs), and dielectrophoretic (DEP) forces, induced by gradient electric fields. Modulating these fields allows for the precise positioning of individual microparticles at points where …
Investigating Cloth Sculpting For Simulation Control In Virtual Reality, Matthew S. Bishop
Investigating Cloth Sculpting For Simulation Control In Virtual Reality, Matthew S. Bishop
Theses and Dissertations
Artists require control and predictability over physically based simulations to create their required animation. This control can lead to reduced iteration time to get the desired simulation results. Controlling cloth simulations can require manual effort to create goal keyframes for control algorithms to match. Current techniques and research utilize a keyboard and mouse to create these goal keyframes. Other research has looked at using a virtual reality (VR) head-mounted display with controllers to improve the experience of completing similar animation tasks. However, we are not aware of any research that attempts to use VR as a tool to assist artists …
Vco Calibration Techniques And Design Of A 0.12-V Ultra-Low Supply Analog-To-Digital Converter, Shea Smith
Vco Calibration Techniques And Design Of A 0.12-V Ultra-Low Supply Analog-To-Digital Converter, Shea Smith
Theses and Dissertations
Many analog-to-digital converters (ADC) quantize inputs using a voltage-controlled-oscillator (VCO). These VCO-based ADCs leverage time-domain processing to shape quantization noise and mismatch, which further increases their appeal. Despite these advantages, achieving good performance with a VCO-based ADC remains a significant challenge due to the nonlinear transfer characteristics of the voltage-to-frequency (V-F) conversion. VCO-based ADCs widely utilize coarse-fine readout to save power and hardware compared to counter-only converters. However, the timing mismatch due to the clock skew between the coarse and fine quantizers can lead to significant reconstruction errors. Chapter 2 proposes a digital calibration circuit to detect and correct coarse-fine …
Examining The Dual Nature Of Post-Mission Mental Health: An Analysis Of Mental Health Symptoms And Positive Well-Being Among Returned Missionaries Of The Church Of Jesus Christ Of Latter-Day Saints, Blaise Dobson
Undergraduate Honors Theses
This study explores mental health and general well-being amongst returned missionaries who served and completed full-time proselyting missions for The Church of Jesus Christ of Latter-Day Saints. Through a combination of survey data and semi-structured interviews with 15 participants, the research investigated emotional, physical, spiritual, and mental changes experienced during their missions, and how those experiences affected them post-mission. Findings show that majority of participants viewed their mission as a positive experience overall, with few reporting on negative experiences. Very few studies have explored returned missionaries and their mental health; not touching on the specific population of missionaries who finish …
Subspace Decomposition Of Linear Secrecy Codes, David Robert Joseph Hunn
Subspace Decomposition Of Linear Secrecy Codes, David Robert Joseph Hunn
Theses and Dissertations
We introduce a new method for the study of linear codes, termed subspace decomposition, which provides new insights into code structure and performance. Briefly, subspace decomposition comprises the evaluation of complex properties of a linear code by evaluating simple properties of its constituent subspaces. We find that this technique has application to a number of problems in coding theory. When applied to the problem of evaluating the performance of secrecy codes, subspace decomposition provides an efficient method for computing the equivocation of coset codes over the binary erasure wiretap channel. It is also especially efficient in computing the chi squared …
Partisanship, Security, And Global Status: Anatomy Of Taiwan’S March 19 Shooting Conspiracy Theories, William Martindale
Partisanship, Security, And Global Status: Anatomy Of Taiwan’S March 19 Shooting Conspiracy Theories, William Martindale
Undergraduate Honors Theses
Previous research has shown how belief in particular conspiracy theories is subject to their salience to believers. Using the example of Taiwan’s March 19 shooting conspiracy theories, I show in this paper that salience is created by appealing to existing collective memory. Additionally, I show that conspiracy theory spreaders help to reinforce the elements of collective memory that make their conspiracy theories salient. Using evidence from primary sources and a representative survey sample, I demonstrate the relevance of three contextual elements in belief in conspiracy theories about the March 19 shooting. These can be summarized as Partisanship, Security, and Global …
