The Crystal Ball Is Cloudy: Teacher Preparation Programs' Challenges In Predicting Effective Teaching From Teacher Characteristics, Benjamin Pacini
The Crystal Ball Is Cloudy: Teacher Preparation Programs' Challenges In Predicting Effective Teaching From Teacher Characteristics, Benjamin Pacini
Theses and Dissertations
Teacher preparation programs (TPPs) stand to benefit if they can reliably link pre-service teacher characteristics with later teaching quality--for example, by better supporting underperformers and spotting high-potential candidates early. In this study, I use data from a university in the Mountain West to analyze the relationships between pre-college student characteristics and teaching evaluation scores during student teaching, as scored on Danielson's Framework for Teaching (FFT) rubric. My findings suggest that no significant relationship exists between FFT scores and demographic characteristics such as age, sex, marital status, or poverty. Pre-college academic variables (i.e., GPA and standardized test scores) show small but …
Pilot Study For Examining The Physiological Effects Of Sustained Attention In A Structured Online Mindfulness-Based Course, Eve Barton
Theses and Dissertations
Mindfulness-based interventions (MBI's) and courses have emerged as widely recognized approaches for promoting mental health, improving cognitive functioning, and fostering overall well-being. This pilot study explored the effects of a 15-session, online, structured mindfulness course on sustained attention and subjective well-being, utilizing both objective and subjective measures. The study aimed to determine whether participants' sustained attention, assessed via a smooth pursuit eye movement (SPEM) task, improved after completing the online course. Subjective attention was measured using the Attentional Control Scale (ACS) and a single item from the Adult ADHD Self-Report Scale (ASRS), while subjective well-being was assessed using the Survey …
Wordsworth's Literary Signposts: Writings On Epitaphs And Tourism, 1807-1835, Matthew W. Rudy
Wordsworth's Literary Signposts: Writings On Epitaphs And Tourism, 1807-1835, Matthew W. Rudy
Theses and Dissertations
This paper explores the intersection of epitaphic language and tourism in the works of William Wordsworth from 1807-1835. Compared to his earlier, more literal epitaphs, works such as "Yarrow Unvisited" (1807) and "Elegiac Stanzas" (1807) demonstrate a shift towards broader epitaphic language that foregrounds the ability of epitaphic texts to invite the reader to pause and make their own connection with the inscribed site. With the publication of "Essay upon Epitaphs" (1810) he further established his theory on the ideal epitaph as text capable of anticipating and connecting anonymous readers to the site and subject, whether inscribed on a headstone …
Enabling Next-Generation Microfluidics Through Advances In High-Resolution 3d Printing, Matthew S. Viglione
Enabling Next-Generation Microfluidics Through Advances In High-Resolution 3d Printing, Matthew S. Viglione
Theses and Dissertations
This dissertation advances the field of microfluidic device fabrication through the development and application of high-resolution 3D printing technologies. The convergence of stereolithography (SLA) with digital light processing (DLP) has created unprecedented opportunities for microfluidic device fabrication, enabling truly three-dimensional structures with feature sizes approaching the single-micron scale. Building upon foundational work in custom 3D printer development, this research addresses critical limitations in 3D printing that have historically constrained microfluidic innovation, spanning multiple generations of custom 3D printers and technical innovations that have enabled the fabrication of increasingly complex microfluidic devices while enhancing resolution, repeatability, speed, and accessibility. A comprehensive …
A Complete Guide To Multi-Fidelity No-U-Turn Sampling With Application To An Inverse Wave Problem, Paul Smith
A Complete Guide To Multi-Fidelity No-U-Turn Sampling With Application To An Inverse Wave Problem, Paul Smith
Theses and Dissertations
We employ a Bayesian framework to solve an inverse problem that aims to identify the initial condition distribution of wave propagation, given a limited set of observable data. To optimize sampling efficiency, we introduce a multi-fidelity No-U-Turn Sampler (MF-NUTS) with an adaptive mass matrix. Maximizing sampling efficiency is crucial, as our ultimate goal is to extend this methodology to a large-scale inverse problem to identify the source parameters of historical tsunami-generating earthquakes. The forward model for tsunami propagation (GeoClaw) requires over 20 minutes of supercomputer time on 24 cores to evaluate each sample for a triple-fault rupture, necessitating a strategy …
Reading "Particularized Worlds": Apocalypse, The Postsecular, And Postcritique In Toni Morrison's A Mercy, Eli Phillips
Reading "Particularized Worlds": Apocalypse, The Postsecular, And Postcritique In Toni Morrison's A Mercy, Eli Phillips
Theses and Dissertations
Toni Morrison’s 2008 novel A Mercy uses the concepts of world and apocalypse to explore a tension between individual perception (what Morrison calls “particularized worlds”) and larger social systems. In so doing, A Mercy reveals the nuanced networks of relationships that define worlds of belief and culture. By exploring its treatment of worlds and apocalypse and its attitudes toward the characters who experience them, this paper argues that Morisson’s work demonstrates a novel and timely readerly disposition, one that provides a more ethical approach to reading literature within the postcritical and postsecular landscape.
Deliberate Practice For Multicultural Orientation Training Novice Undergraduates, Eduardo E. Duran
Deliberate Practice For Multicultural Orientation Training Novice Undergraduates, Eduardo E. Duran
Theses and Dissertations
This study explores the efficacy of Multicultural Orientation (MCO) and Motivational Interviewing (MI) frameworks in enhancing undergraduates' ability to address cultural dynamics in therapeutic contexts through deliberate practice. Using a randomized control trial design, 59 participants were assigned to either an MCO as the experimental group or an MI workshop as the control group, each involving pre- and post-workshop video simulations and self-reported assessments. The workshops incorporated deliberate practice exercises with feedback to improve participants' responses to culturally rich client scenarios. Findings indicated significant improvements in cultural humility, comfort, and opportunities for the MCO group compared to the MI group. …
A Low-Cost Micro Actuator Driven By Electrowetting-On-Dielectric, Behzad Parsi
A Low-Cost Micro Actuator Driven By Electrowetting-On-Dielectric, Behzad Parsi
Theses and Dissertations
Microfluidic techniques have been shown to address limitations of reconfigurable radio frequency (RF) antennas and filters in efficiency, power handling capability, cost, and frequency tuning. However, the current devices suffer from significant integration challenges associated with packaging, actuation, and control. Recent advances in reconfigurable microfluidics that utilize the motion of a selectively metalized plate (SMP) for RF tuning have demonstrated promising RF capabilities but have exposed a need for an accurate fluid actuation model. This research presents models for the dynamics of plate actuation under multiple scenarios. In the first phase, the mechanical motion of a moving plate (e.g. SMP) …
Studies Evaluating Practices For Water Conservation: In-Situ Sensors For Determining Soil Field Capacity And Water Application Savings From Rebate-Driven Residential Landscape Transformations, Madison E. Martini
Theses and Dissertations
Water conservation is a critical issue that requires solutions to address growing water scarcity. In both agricultural and urban settings, targeting conservation efforts is essential for lasting progress as well as protection of communities and ecosystems. This research focuses on identifying practical means to reduce water use by studying separate conservation strategies in urban and agricultural contexts. Given their interdependence, addressing water use in both sectors is essential for achieving meaningful and lasting conservation outcomes. Agricultural water conservation relies on efficient irrigation practices, which depend on accurately determining soil field capacity (FC)--the amount of water soil can retain after excess …
Ledger Lines And Lines Of Flight: Borges, Deleuze, And Music, Kaitlyn Thiriot Morin
Ledger Lines And Lines Of Flight: Borges, Deleuze, And Music, Kaitlyn Thiriot Morin
Theses and Dissertations
This paper discusses the purpose of musical inclusions within several of Jorge Luis Borges’s short stories through Deleuzian lines of flight. The common consideration of music in Borges’s works focuses primarily on his usage of the tango and milonga due to Borges’s own personal interests. This paper argues that Borges utilizes not only the tango but also other styles of music as a pathway of transcendence, temporarily allowing characters to surpass the limitations of mortality. The paper will first analyze Deleuze and Guattari’s formula on escaping organization, and the relationship between the rhizome, lines of flight, deterritorialization, and the body …
Optimizing Aircraft Taxi Processes: A Novel Cost-Minimizing Queue Discipline For The Pushback To Runway Process, Kevin James
Optimizing Aircraft Taxi Processes: A Novel Cost-Minimizing Queue Discipline For The Pushback To Runway Process, Kevin James
Theses and Dissertations
Optimization of the aircraft taxi process can significantly decrease operating costs for air carriers, especially at major airports where congestion on the ramp is a primary contributor to taxi times. To improve the efficiency of this process, we propose a novel queue discipline which mitigates pushback delays through a dynamic reordering of clearance deliveries. As an alternative to FIFO, the proposed discipline accounts for aircraft delays at the gate before the aircraft enters the queueing system. Our proposed system implements pushback control to allow for controller-imposed variability in runway queueing. To validate our proposed queue discipline, we provide a computational …
Heavy Ion Testing Of Versal Acap Ai Engines, Caleb S. Price
Heavy Ion Testing Of Versal Acap Ai Engines, Caleb S. Price
Theses and Dissertations
With recent developments in artificial intelligence (AI), there has been an ever increasing need for computation power in space. These AI models are traditionally implemented on GPUs. However, these units come at a high cost in terms of weight and power usage. Due to these limitations, many organizations are turning to the Versal ACAP device, a system on chip (SOC) with hundreds of AI engines. This option delivers more computation per watt than a traditional GPU. The desire to use Versal ACAP in space has created a need to perform radiation testing on the device. Extensive testing has been performed …
Gnss-Denied Navigation Using Lte Signals Of Opportunity On Low-Cost, Low-Swap Hardware, Tyler Sweat
Gnss-Denied Navigation Using Lte Signals Of Opportunity On Low-Cost, Low-Swap Hardware, Tyler Sweat
Theses and Dissertations
Global navigation satellite system (GNSS) navigation is crucial in the operation of unmanned aerial vehicles (UAV). GNSS signals are susceptible to jamming, spoofing, multipath, and urban canyons and may provide incorrect position information or may not be available at all. For autonomous missions, a backup for GNSS is desirable in the event that it is unavailable. Terrestrial cellular signals are a promising option for navigation because they are continuously transmitted at higher power levels. Optimizing hardware size, weight, and power (SWaP) is critical for UAVs to maximize endurance, payload capacity, and operational efficiency. We present a system that uses long-term …
Understanding Dialogic Interactions In Online Religious Education, Isaac Munoz Moreno
Understanding Dialogic Interactions In Online Religious Education, Isaac Munoz Moreno
Theses and Dissertations
In this study, I explored how Latter-day Saint higher education professors experienced and facilitated dialogic interactions in online religion courses. Seven instructors who taught synchronous and asynchronous virtual courses at Brigham Young University participated in semi-structured interviews focused on their pedagogical approaches, relational practices, and perceptions of student engagement. Guided by hermeneutic phenomenology and drawing on principles of dialogic pedagogy, I explored how religion instructors cultivated dialogue in virtual classrooms grounded in doctrinal instruction. The findings revealed how professors created a relational presence, navigated institutional constraints, and fostered deep learning and spiritual growth environments. While some participants viewed online dialogue …
Measuring The Effects Of The Leaves On Stalk Strength And Dynamic Response In Maize, Grant C. Ogilvie
Measuring The Effects Of The Leaves On Stalk Strength And Dynamic Response In Maize, Grant C. Ogilvie
Theses and Dissertations
Maize is one of the most widely cultivated grains in the world, making it crucial to world food security and important economically. One major problem in maize production is stalk lodging (greensnap), which results in billions of dollars in lost harvests annually for maize farmers in the US alone. Understanding the mechanical properties of maize plants is crucial to addressing this problem. Previous studies have suggested that the leaf blades and leaf sheaths affect maize mechanical properties. The objectives of this thesis are twofold: to present measurement techniques for the stalk bending strength, damping ratio, and natural frequency of maize …
A Novel Wrench Decomposition And Development Of A Large-Scale Soft Robot For Displacement-Based Human-Robot Collaborative Manipulation, Dallin Cordon
A Novel Wrench Decomposition And Development Of A Large-Scale Soft Robot For Displacement-Based Human-Robot Collaborative Manipulation, Dallin Cordon
Theses and Dissertations
This work represents an examination of various facets of physical human-robot collaborative manipulation and the implementation of compliant, soft-robotic manipulators. A survey of physical human-human interaction and haptic communication is presented, alongside an investigation into the decomposition of force and torque components that enable effective human-robot collaboration. To address the inconsistent terminology found in previous literature, a standardized framework for force decomposition is proposed. A new taxonomy is introduced to categorize the force components involved in collaborative manipulation tasks. This taxonomy clarifies the role of each component in an agent's applied force during task execution and provides a structured framework …
Testing And Modeling Of Nonlinearities In Riveted And Bolted Structures, Joshua E. Blackham
Testing And Modeling Of Nonlinearities In Riveted And Bolted Structures, Joshua E. Blackham
Theses and Dissertations
Joints are difficult to model because of various small-scale and nonlinear features, such as local geometry, preload, friction and contact. These features cause a local change in stiffness and energy dissipation which result in changes in the effective natural frequency and damping of the whole structure. Past studies have found good success using nonlinear Iwan elements as whole joint models for bolted joints in a few different structures. In Chapter 3, a similar approach is proposed for modeling riveted joints, which seeks to capture the vibrational response of a test structure including changes in the effective modal frequency and damping …
Wind Collapse Risk And Serviceability Drift Of Steel Concentrically Braced Frame Buildings, Sarah Corrinne Partington Cluff
Wind Collapse Risk And Serviceability Drift Of Steel Concentrically Braced Frame Buildings, Sarah Corrinne Partington Cluff
Theses and Dissertations
Seismic design provisions use the ductility and reserve strength of the lateral structural system to reduce the loads used in design, making the structural design more economical while maintaining life safety. In contrast, current wind design provisions do not. Conventional wind design relies primarily on elastic behavior. The objective of this study is to determine a wind response modification factor for steel concentrically braced frames that could be applied to reduce wind design loads based on ductility and reserve strength, while still meeting drift requirements for serviceability of the structure. To achieve the objective, three types of ductile braced frames …
"Our Darker Purpose": Jean-François Ducis's Le Roi Léar In Eighteenth-Century France, Zerin Biehn
"Our Darker Purpose": Jean-François Ducis's Le Roi Léar In Eighteenth-Century France, Zerin Biehn
Theses and Dissertations
Jean-François Ducis's French adaptation of Shakespeare's King Lear has received little critical attention since its publication in 1784. The play retains many of the main plot points that are familiar from Shakespeare along with Ducis's changes that helped make Shakespeare and King Lear more acceptable for the French stage. John Golder has interpreted Le Roi Léar as a pro-royalist play, but I argue that the play's portrayal of kingship and treason is much more nuanced. Ducis's Cordelia is framed for rebellion by her oldest sister, a situation which lacks the rich ambiguity of Shakespeare's Cordelia refusing to placate her father …

From Casa To Career: Language Domains Of Adolescent Heritage Spanish Speakers In The United States, Rachel Emily Koncurat
Theses and Dissertations
Adolescence is a critical time for identity development. At this stage, it is important that heritage speakers hear positive messages about their heritage language and have programs that meet their linguistic needs and aspirations. This thesis examines the sociolinguistic domains in which adolescent heritage Spanish speakers use English and Spanish. It addresses two key questions: 1) In what domains do adolescent heritage Spanish speakers use English and Spanish? 2) Do these domains align with the future contexts in which they wish to use Spanish? To answer these questions, I distributed an online survey about language domains and future language goals …
Steps Towards Effective Human-Robot Co-Manipulation Through Real-Time Modus Detection And Effects Of Stiffness Variation For Human-Soft-Robot Dyads, Shaden Moss
Theses and Dissertations
A group of individuals can coordinate very easily to carry a large or heavy object together. This act of collaborative carrying is called co-manipulation. Unlike human teammates, robots cannot easily detect and respond to the intent of human partners during co-manipulation tasks. This shortcoming can be compensated for via the physical design and the software design of robots. This work treats software design with a neural net that detects human modus (or the manner in which a team moves an object together) in real time. This work treats physical design with the use of a soft robot in human-robot co-manipulation, …
Improving Devices To Measure The Thermal Conductivity Of Molten Halide Salts, Ryan J. Ruth
Improving Devices To Measure The Thermal Conductivity Of Molten Halide Salts, Ryan J. Ruth
Theses and Dissertations
Molten salts are of high interest for use in nuclear reactors, though their thermophysical properties are notoriously hard to measure due to the extreme conditions created by them. Significant gaps remain in thermal conductivity and heat capacity data, which this work seeks to fill by improving the Needle Probe-a modified transient hot wire probe originally used by Merritt et al to measure the thermal conductivity of FLiNaK- measuring two new salts, and exploring new materials for use with molten salts. Improvements made to the Needle Probe include automation to reduce human error, more accurate heat generation modeling, a more thorough …
Strength And Ductility Of Rod-Braced Diaphragms In Metal Building Systems Subjected To Earthquake Ground Motions, James Niedens
Strength And Ductility Of Rod-Braced Diaphragms In Metal Building Systems Subjected To Earthquake Ground Motions, James Niedens
Theses and Dissertations
Metal building systems are a common form of construction but the behavior of roof diaphragms in metal buildings that are subjected to earthquake ground motions is not entirely understood. In this study, the strength and ductility of rod-braced diaphragms with hillside washer connections or rod-pad connections was determined using experimental tests and computer simulation. Tensile tests of rods were used to determine the effect of the type of rod on strength and ductility. Two types of rods were tested, full-body rods with cut threads at each end of the rod and bracing rods with rolled threads. Three rod sizes (5/8 …
A Levinasian Investigation Of Leaders Learning Humility, Spencer Fumio Yamada
A Levinasian Investigation Of Leaders Learning Humility, Spencer Fumio Yamada
Theses and Dissertations
This dissertation examines the development of humility in individuals and business organizations. Humility in business leadership has received increased attention in recent years; however, little is known regarding how individuals and organizations become more humble. The first article in this dissertation is a theoretical examination of humility and argues that the philosophy of ethicist and phenomenologist Emmanuel Levinas provides a theoretical lens by which the development of humility could be productively explored. Levinas argued that the human experience is based on the ethical responsibility that individuals have towards one another, providing a set of assumptions for an examination of professional …
Supporting Female Nontraditional Students In Higher Education: Exploring Instructors And Instructor Leads' Experiences, Adriana Alba
Supporting Female Nontraditional Students In Higher Education: Exploring Instructors And Instructor Leads' Experiences, Adriana Alba
Theses and Dissertations
Women nontraditional students--defined as those who are over 25, delay college enrollment after high school, attend part-time, have dependent children, are single parents, work full-time while studying, or are financially independent--face unique challenges balancing academic pursuits with family and professional responsibilities in online education, yet research on effective support practices remains limited. This study examined the experiences of six BYU-Pathway Worldwide instructors and instructor leads (four instructors and two instructor leads) who support predominantly women nontraditional students in online courses. Using interpretative phenomenological analysis (IPA) of in-depth interviews and follow-up conversations, the research explored how instructors navigate supporting these students. …
Integrating Temperature-Dependent Tissue Properties Into Hifu Computational Models For Enhanced Treatment Planning, Christian Kevin Valencia Narva
Integrating Temperature-Dependent Tissue Properties Into Hifu Computational Models For Enhanced Treatment Planning, Christian Kevin Valencia Narva
Theses and Dissertations
Objective: High-intensity focused ultrasound (HIFU) is a non-invasive therapy that ablates diseased tissues with high precision. Computational simulations using the Pennes Bioheat Transfer Equation (PBTE) can guide HIFU treatment by predicting temperature distributions and thermal dose volumes. Traditional simulations assume constant thermal and acoustic properties, which may oversimplify tissue behavior. Methods: This study evaluates the impact of integrating temperature-dependent thermal properties (thermal conductivity, specific heat capacity, and perfusion) in finite-difference time-domain HIFU simulations. Three scenarios were simulated: (1) a homogeneous liver with both high- and low-power sonications, (2) a rabbit thigh muscle validated against preclinical MRTI data, and (3) an …
Development Of A Qualitative Spot Assay For Zinc Detection In Fortified Cereal Grain Matrices, Ashley L. Lamborn

Theses and Dissertations
The present thesis is a compilation of a literature review, journal manuscript, and two standard operating procedures (SOP) on the qualitative determination of zinc in fortified cereal grain products and matrices. The literature review addresses the premise of the research as well as potential solutions for the development of a rapid qualitative spot assay for zinc determination. Quality assurance assays affirm the presence of micronutrients in food fortification initiatives, but no rapid qualitative spot methods for the assessment of zinc currently exist. Chromogenic reagents that may perform a key role in the rapid determination of zinc are identified. The journal …
Development And Evaluation Of Canbench: A Testbed For Assessing The Security Of Automotive Can Buses, Trevor S. Mcclellan
Development And Evaluation Of Canbench: A Testbed For Assessing The Security Of Automotive Can Buses, Trevor S. Mcclellan
Theses and Dissertations
Modern vehicles rely heavily on electronic control units (ECUs) that communicate via the controller area network (CAN) bus, a protocol developed in the 1980s with minimal security considerations. The growing number of ECUs has heightened the risk of cyberattacks on vehicles. Although CAN bus security has been extensively researched, the CAN standard still lacks built-in security measures. Furthermore, testing proposed security mechanisms is challenging due to the proprietary nature of automotive systems. To address this, an open-source physical testbed was developed using inexpensive, off-the-shelf components to support automotive CAN bus security research. The testbed provides a controlled environment for simulating …

Reservoir Characterization And Basin Modeling Of Mesozoic Siliciclastic Strata For Sedimentary Geothermal Exploration, Iron County, Utah, Theodore L. Morgan
Theses and Dissertations
The transition zone between the Colorado Plateau and Basin and Range provinces of southwestern Utah provides excellent opportunities for future geothermal resource development. A combination of large fault-controlled extensional basins with outcrop analogs along basin margins, an elevated heat flow and thermal regime and the presence of porous and permeable sedimentary formations within extensional sedimentary basins allow for sedimentary geothermal exploration and development. Utilizing a reservoir-centered approach has the potential to dramatically expand the economic limits of geothermal plays in both established and frontier basins. This study characterizes a sedimentary geothermal system in Iron County Utah, centered on the Escalante …
Analysis Of Nitrogen Accumulation And Gene Expression In Hydroponically-Grown Chenopodium Genotypes, Teal Kalt
Analysis Of Nitrogen Accumulation And Gene Expression In Hydroponically-Grown Chenopodium Genotypes, Teal Kalt
Theses and Dissertations
Nitrogen (N) is an essential macronutrient required by all plants to complete their life cycles. Inefficient N uptake contributes to over fertilization and subsequent environmental and sustainability issues resulting in the need for improved nitrogen use efficiency (NUE). Chenopodium quinoa is a resilient pseudocereal crop that is relatively adapted to N-deficient soils. Previous studies have uncovered the unique genetic structure of quinoa and its physiological responses to N availability; however, gaps remain in understanding its molecular mechanisms for NUE. This study investigates four quinoa genotypes (Real-1, 0654, KU-2, and QQ74) hydroponically grown in N-deficient conditions. RNA sequencing (RNA-seq) analysis identified …
