Measuring Support For Democracy Through Public Understanding: A Conjoint Survey Approach, Kendra Pinegar

Undergraduate Honors Theses

In this thesis, I explore how individuals conceptualize democracy and whether their support is based on democratic principles or its outcomes. Using a conjoint experiment in Chile and Peru, I examine how respondents define democracy, assess governance, and adjust their support based on institutional attributes. My findings show that citizens struggle to distinguish between democracy’s core institutions and the broader social and economic conditions they associate with it. Their support is often tied to government performance rather than democratic principles. Moreover, they favor their own definition of democracy over an objective, institutional one, revealing a disconnect between public perception and …

The Readable Scriptures: Creating A Dyslexia-Friendly Book Of Mormon, Elijah Pearce

Undergraduate Honors Theses

This thesis appears in two parts. The first is a 135-page project where I have implemented features and practices to aid the readability of the Book of Mormon for individuals with dyslexia. The second part of this thesis is an analysis where I present a brief literature review of dyslexia and my method of applying these features and practices to a section of the English Book of Mormon, namely, the twenty-two chapters that comprise 1 Nephi. This project is not intended to present a format that will aid all individuals with dyslexia, nor is this project a complete, finished work—it …

Lgbtq+ Identity Development And Individual Vs Group Psychotherapy Experience: A Consensual Qualitative Analysis, Aileen Marie Rands

Theses and Dissertations

Multicultural topics, such as LGBTQ+ experience, have accrued predominance within the field of psychology. It has become clear that better understanding minority experience is of utmost importance. Pervasive stigma, discrimination, and mistreatment culminate into minority stress; thus LGBTQ+ individuals face greater risk for poor mental health and seek out psychotherapy at higher rates. Despite this reality, limited psychotherapy research exists in this area generally and essentially no research has looking into the experience of LGBTQ+ individuals in group therapy. The current study investigated experiences of LGBTQ+ clients who have participated in both individual and group psychotherapy. Eleven participants were interviewed …

Enhancing Mucus Flow And Clearance By Grafting Zwitterionic Hydrogel Films To Luminal Surfaces, Ryan Horne, Caleb Escudero, Morgan Ellerman, C. Allan Guymon, Marlan Hansen

Faculty Publications

Objective

To determine the effects of zwitterionic hydrogel films on mucus contact angles, flow, and stasis with respect to medical polymer surfaces, both flat and tubular.

Methods

A zwitterionic hydrogel thin film was photografted onto medical rubber surfaces and compared against non-zwitterionic hydrogel thin films and untreated surfaces to determine its impact on mucus contact angles, mucus flow on sheets and tubes, and mucus plugging.

Results

Zwitterionic and conventional hydrogel films significantly reduce the mucus contact angles and the tilt required to initiate mucus flow on sheets and in tubular systems. Preliminary experiments show that these films may also shorten …

Uncertainty Propagation And Sensitivity Analysis For Constrained Optimization Of Nuclear Waste Vitrification, Lagrande Gunnell, Xiaonan Lu, John D. Vienna, Dong-Sang Kim, Brian J. Riley, John Hedengren

Faculty Publications

The vitrification of high-level waste (HLW) by heating a mixture of glass-forming chemicals (GFCs) with the waste can be improved using a constrained optimization problem. This study explores how different uncertainty propagation (UP) methods implemented with the optimization process can affect the glass formulation of nuclear waste glasses. UP is the effort of propagating uncertain inputs through a system to understand and quantify output distributions. Uncertainty intervals are crafted from output distributions to inform the optimization algorithm. UP is often implemented with Monte Carlo (MC) sampling for large nonlinear systems, which can be difficult to implement within a constrained optimization …

Sustainable Well-Being For Young Adults: An Online Course To Build Ecological And Psychological Flourishing In A Changing Climate, Jeremy Stanley Bekker

Theses and Dissertations

Sustainable well-being is "happiness that contributes to individual, community and/or global well-being without exploiting other people, the environment or future generations" (O'Brien, 2010, p. 2). Sustainable well-being education may encourage environmentally sustainable behavior while also teaching people how to live meaningful lives. However, there is currently a lack of research-based disseminable courses for teaching sustainable well-being. We hypothesized that taking the course would result in lower eco-anxiety and higher well-being, as well as increased pro-environmental self-efficacy and pro-environmental values. We used a randomized crossover repeated measures research design to assess pre and post effects. Quantitative results indicated that participating in …

What Counselors Say Matters For Supporting High School Newcomer Multilingual Learners As They Work Toward Graduation, Sonia Lucrecia Molina Openshaw

Theses and Dissertations

This thesis explores how high school (HS) counselors describe their work with newcomer multilingual learners (MLs). Using the lens of Yosso’s (2005) Community Cultural Wealth (CCW) framework to identify asset perspectives in their work with these students. They suggest specific supports and barriers impacting these students' academic and social success in school. Findings reveal that counselors often focus on addressing the immediate needs of HS newcomer MLs, such as language acquisition and academic readiness, but less frequently recognize the cultural, linguistic, and social assets students bring to their educational journey. Counselors highlight the importance of systemic supports, including onboarding processes, …

Post-Irradiation Fault Injection For Complex Fpga Designs, Nathan G. Baker

Theses and Dissertations

Fault injection is a common technique for estimating the impact of single-event upsets (SEUs) within the configuration memory (CRAM) of an FPGA design. Fault injection is typically conducted prior to a radiation test to evaluate the effectiveness of SEU mitigation techniques, estimate the FPGA design's behavior at the radiation test, and prepare the radiation test infrastructure. This thesis explores how fault injection can be used after radiation testing to reveal additional insight into an FPGA's behavior during a radiation test. A unique methodology, referred to as post-irradiation fault injection (PIRFI), was developed in which the locations and timestamps of CRAM …

A Multi-Model And Multi-Agency Approach To Expand The Flood Inundation Mapping Capacity Of The Us National Water Center, Samuel Jay Oldham

Theses and Dissertations

The most accurate numerical model for simulating flood extents of rivers has long been a subject of debate. While specialized models exist for specific hydraulic features, we advocate for the principle that the best model is the one the user is familiar with, has adequate data to support input requirements and limitations, and will consistently employ. To support this approach, we have developed a database schema optimized to store riverine flood inundation model output files. This schema is designed to assist U.S. cities, counties, states, and other flood management agencies in leveraging their existing model-generated flood maps, regardless of the …

Potential Of Individual Upper-Limb Muscles To Contribute To Postural Tremor: Simulations From Neural Drive To Joint Rotation, Spencer A. Baker, Landon J. Beutler, Daniel B. Free, Dario Farina, Steven Knight Charles

Faculty Publications

Background: It is unclear which muscles contribute most to tremor and should therefore be targeted by tremor suppression methods. Previous studies used mathematical models to investigate how upper-limb biomechanics affect muscles’ potential to generate tremor. These investigations yielded principles, but the models included at most only 15 muscles. Here we expand previous models to include 50 upper-limb muscles, simulate tremor propagation, and test the validity of the previously postulated principles. Methods: Tremor propagation was characterized using the gains between tremorogenic neural drive to the 50 muscles (inputs) and tremulous joint rotations in the 7 joint degreesof- freedom (DOF) from shoulder …

Microfabrication Of Sic Using Femtosecond Lasers, Jared Eldon Payne

Theses and Dissertations

Silicon carbide (SiC) is a desirable material in a wide variety of semiconductor fields. The impressive thermal, chemical, and mechanical properties that make SiC an attractive material also make it very difficult to machine. New fabrication techniques are required to take full advantage of the potential of SiC. First, a new 3-dimensional (3D) non-line-of-sight (NLOS) fabrication technique using two-photon absorption is demonstrated in SiC. NLOS microchannels are shown with aspect ratios higher than 100:1. The process is the only method known, at this time, that can create truly 3D subsurface structures in SiC without direct line of sight to the …

Materiality In The Csr-Investor Reaction Relationship: A Replication And Extension Of Flammer (2013), Steven D. Kofford, Myles Melancon, Ben W. Lewis

Faculty Publications

We replicate and extend Flammer’s (2013) event study of investor reaction to environmental corporate social responsibility (CSR). Flammer found that investors reacted positively to eco-friendly events and negatively to eco-harmful events from 1980-2009 and that reaction to positive events decreased while reaction to negative events increased over time. We find similar results for Flamer’s original sample and an expanded sample including the same type of firms (U.S.-listed public firms) from 1980-2019. We then extend Flammer’s results by examining how materiality affects investor reaction over time. We find that investors only react to material events and that positive reaction to material …

Filipino American Parents' Experiences With The United States Special Education System: A Qualitative Study, Greyagail Custodio Surio

Theses and Dissertations

While there have been studies on Asian American (AA) parents' experiences with the U.S. special education (SPED) system, there have been no studies on Filipino American (FA) parents' experiences with the SPED system. As FAs are the third largest Asian group in the United States., there is a need for special education research to be conducted with this population. Interpretative phenomenological analysis (IPA) interviews were conducted over Zoom with FA parents of children receiving SPED services. Participants resided in various states in the United States (n = 10). Participants reported varied and nuanced experiences related to advocacy, working with the …

A Randomized Controlled Study Of Heart Rate Variability Biofeedback In An Older Adult Sample, Whitney D. Allen

Theses and Dissertations

Heart rate variability biofeedback (HRVB) is a controlled breathing treatment designed to increase the variation in consecutive heartbeats leading to improved regulation of one's autonomic nervous system thereby improving one's ability to self-regulate and maintain homeostasis. Changes in heart rate variability (HRV) are seen in those of increased age and lower HRV is associated with poorer outcomes (e.g., increased mortality, worse emotional functioning, cardiovascular risk factors). As such, older adults are a group that stands to benefit from HRVB principles. The current randomized control trial was designed to understand the impact of HRVB in an older adult population on resting …

Interfacial Phenomena In Molten Salt Systems And Wetting Transitions In Microcavities, Aaron Essilfie

Theses and Dissertations

Interfacial phenomena are the processes that occur at the interface between two phases of matter: solid-liquid, solid-gas, liquid-liquid, and liquid-gas. Wetting, spreading, adsorption, and capillarity are some features of interfacial phenomena. This research explores two areas of interfacial phenomena: the interfacial tension between a liquid and gas, and wetting transitions in microcavities. Surface tension has been a widely studied topic in surface chemistry. Many techniques have been employed to study the surface tension of liquids in various studies and research areas, but the interfacial tension between a liquid and gas has not been extensively researched. For this reason, part of …

Adapting Biological Mechanisms Into Machine Learning Structures And Gradient Propagation, Hao Yu

Theses and Dissertations

As neuromorphic computing gains traction, researchers look for learning schemes that are more suitable for brain-like structures. Although many algorithms have been discovered, such as surrogate gradient or Spike Timing Dependent Plasticity, those algorithms are either unsuitable for on-chip training or not biologically aligned. The goal of this thesis is to discover a learning algorithm which is biologically aligned and suitable for on-chip training. Through the discoveries of our two papers, we are able to introduce the concepts of synaptic clefts and neurotransmitters into a common spiking neuron network. We also designed an error propagation method aligning with biology. With …

A Literary Review On The Effects Of Music Therapy On Depressed Adolescents: Brain Function, Individual Therapy, And Group Psychotherapy, Bella Mccain

Intuition: The BYU Undergraduate Journal of Psychology

This paper presents a literature review examining the impact of music therapy on adolescents with major depressive disorder (MDD). Music therapy, officially recognized in 1950, is a clinical intervention that addresses various psychological and cognitive deficiencies. Adolescents show a strong affinity for music, making it a potential treatment for depression, which is prevalent among this age group. This review explores studies focused on music therapy’s effects on brain function, individual psychotherapy, and group therapy for adolescents. Research suggests that music therapy positively influences brain activity by reducing cortisol levels and shifting brainwave patterns towards healthier states. In individual therapy, music …

Finding Meaning In Psychotherapy: A Literature Review Of Logotherapeutic Methodology In Psychotherapeutic Treatment, Jason M. Hoskin

Intuition: The BYU Undergraduate Journal of Psychology

Frankl’s logotherapy is a meaning-centered therapy, focusing on finding personal life purpose to improve one’s psychological well-being, particularly during personal struggle and suffering (Frankl, 1992). This literature review analyzes the empirical research measuring the efficacy of logotherapy in psychotherapy with a total of 27 articles from 2012–2022 reviewed and analyzed. Results illustrates that published contemporary empirical research on this topic focuses mainly on studying (1) theoretical principles of logotherapy through survey data, (2) the efficacy of logotherapy-based groups psychotherapy for individuals, or (3) psychometrics of frequently used instruments for measuring meaning in life. Overall, these categories corroborate the finding that …

Streamlined Production, Protection, And Purification Of Enzyme Biocatalysts Using Virus-Like Particles And A Cell-Free Protein Synthesis System, Seung O. Yang, Joseph P. Talley, Gregory H. Nielsen, Kristen M. Wilding, Bradley Charles Bundy

Faculty Publications

Enzymes play an essential role in many different industries; however, their operating conditions are limited due to the loss of enzyme activity in the presence of proteases and at temperatures significantly above physiological conditions. One way to improve the stability of these enzymes against high temperatures and proteases is to encapsulate them in protective shells or virus-like particles. This work presents a streamlined, three-step, cell-free protein synthesis (CFPS) procedure that enables rapid in vitro enzyme production, targeted encapsulation in protective virus-like particles (VLPs), and facile purification using a 6× His-tag fused to the VLP coat protein. This process is performed …

Using Unmanned Aerial Vehicles To Facilitate Traffic Incident Management, Adam William Hill

Theses and Dissertations

Incident management teams (IMTs) minimize crash impacts and create a safer highway network for people and communities. Research has shown that optimizing the IMT fleet has strong benefits to the roadway network, but future models indicate that increasing IMT presence may have diminishing returns after excessive roadway saturation. The Utah Department of Transportation (UDOT) would like to improve situational awareness in areas of poor or limited camera coverage, where situational awareness is typically poor. UDOT is considering the use of unmanned aerial systems (UAS) to provide live camera coverage of traffic conditions in these instances. This thesis synthesizes practice from …

Navigating The World Of Online Information: A Braided Approach To Research And Writing In Ela Classrooms, Ana Katz, Brittany Malloy

The Utah English Journal

As ELA teachers, we know that teaching students how to write well goes beyond grammar and thesis statements–it is about empowering students to think critically in a world overflowing with information. Whether it is news headlines, social media posts, or academic articles, our students are constantly navigating a sea of facts, opinions, and misinformation. The challenge? Equipping them with the skills to tell the difference. One approach that positively impacted our classrooms was integrating research and writing into a single process. This “braided” method teaches students how to evaluate sources and build strong arguments while keeping their engagement high and …

The Summer Of Ya Love: Young Adult Romance, Tiktok, And The Classroom, Annika Nielson

The Utah English Journal

Where teenagers are, there romance will be also. As a high school English teacher, I constantly witness the intensity of adolescence as young people start to explore their own identities. It is impossible to separate this time of teenagerdom from romance, since “adolescents are fascinated with developing sexuality and love” (Litton, 1994, p. 28). Even if they are not experiencing it firsthand, teens are hearing about it constantly from their friends, in school hallways, in the movies and tv shows they consume, and especially in the literature they read. Even the core texts in high school echo this desire for …

A Cohort Of The Willing: How Secondary Schools Might Face The Literacy Crisis, Michelle A. Barney

The Utah English Journal

Experts like Louisa Moats and anyone who has recently completed LETRS (Language Essentials for Teachers of Reading and Spelling) training, know that 95% of children can be taught to read (Louisa Moats, 2023). As a secondary educator, it’s tempting to see this statistic and ignore it. Surely, this must be someone else’s problem. In fact, if all goes according to plan in the world of elementary education, students become proficient at foundational reading skills before fourth grade, especially if one considers Kilpatrick’s work which establishes this benchmark for the development of advanced phonological awareness skills (Kilpatrick, 2015, p. …
