Insights Into Cortical Organization And Executive Dysfunction In Pediatric Traumatic Brain Injury, Madeleine Reading
Insights Into Cortical Organization And Executive Dysfunction In Pediatric Traumatic Brain Injury, Madeleine Reading
Theses and Dissertations
Cortical gyrification is essential for cognitive development, yet its relationship with executive functioning (EF) in pediatric traumatic brain injury (TBI) remains unclear. This study examined whether children with TBI exhibit atypical cortical folding in EF-related regions and whether these differences relate to EF performance. Using FreeSurfer 7.1.1, we analyzed local gyrification index (LGI) in 206 participants (ages 5-18) from 14 sites within the ENIGMA Pediatric msTBI Working Group. Vertex-wise regression revealed that longer time since injury (TSI) was associated with increased gyrification in the right fusiform gyrus and multiple left-hemisphere regions, suggesting region-specific neuroplasticity. Contrary to expectations, higher GCS scores …

Assessment Of Entrepreneurial Mindset In Undergraduate Engineering Students Using Quantiative, Qualitative, And Multi-Methods Approaches, Alexandra Mary Jackson
Theses and Dissertations
The Entrepreneurial Mindset (EM) has been acknowledged as beneficial for engineers entering the workforce in a constantly advancing society. With an EM, professional engineers are better equipped to be innovative, creative, and translate ideas into reality. However, assessing how students develop an EM has been plagued with difficulties, mainly due to the discrepancy in EM definitions between different fields. This dissertation applies three EM assessment methods guided by one theoretical framework: the Triad of EM, which contextualizes EM into cognitive, behavioral, and emotional dimensions. Chapter 3 of this work analyzes EM across multiple years of an undergraduate engineering curriculum using …
The Effect Of Lexical Characteristics On Speech Pausing For People With Broca's Aphasia, Anna Kathryn Walker Smith
The Effect Of Lexical Characteristics On Speech Pausing For People With Broca's Aphasia, Anna Kathryn Walker Smith
Theses and Dissertations
This study examines the connection between speech pause patterns and the lexical characteristics of the words that follow. Speech samples of 16 people with moderate Broca's aphasia and 16 age-matched neurologically healthy controls were evaluated in terms of word length, word frequency in the English language, syntactic category, and articulatory complexity. In general, people with aphasia (PWA) produced pauses more frequently before monosyllabic, very high frequency words with lower articulatory complexity, most of which were content words. The length of these pauses did not significantly correlate with any of the lexical factors examined in this study. The control group had …
Relationship Between Speaking Proficiency And Cultural Identity Of Korean Heritage Language Speakers, Minha Lee
Relationship Between Speaking Proficiency And Cultural Identity Of Korean Heritage Language Speakers, Minha Lee
Theses and Dissertations
Heritage language speakers from immigrant families often navigate between two languages and cultures as they form their personal identities. In this process, some develop their identity through their personal choices and external pressures, while others remain in a state of identity confusion. Although many factors contribute to the formation of their identity, the field of language education has continued to focus on the relationship between language proficiency and identity, assuming language ability could be one of the key influences. This study investigated the relationship between Korean speaking proficiency and cultural identity among Korean heritage language speakers born in the United …
Hybrid Bermudagrass Drought Tolerance In A Cool-Season Climate, Ashley J. Beazer
Hybrid Bermudagrass Drought Tolerance In A Cool-Season Climate, Ashley J. Beazer
Theses and Dissertations
Kentucky bluegrass (Poa pratensis L.) (KBG) is the most commonly grown cool-season C3 turfgrass. However, as global temperatures rise, KBG struggles to tolerate higher temperatures, leading to increased irrigation demands--a growing concern in arid and semi-arid regions facing escalating drought conditions. In contrast, hybrid bermudagrass (HBG; Cynodon dactylon [L.] Pers. x Cynodon transvaalensis Burtt Davy), a warm-season C4 grass, has demonstrated promising adaptability in traditionally cool-season climates. Since 2008, HBG has been successfully grown with minimal winterkill in Provo, UT, USA, and is now being considered for broader adoption in similar climates. Two separate studies were conducted to evaluate the …

Examining Shifts In Reader Identity Through Explicit Fluency Instruction, Mercedes Allen
Examining Shifts In Reader Identity Through Explicit Fluency Instruction, Mercedes Allen
Theses and Dissertations
Fluency-a reader's ability to read accurately, with correct expression, speed, and prosody-is a main component of the science of reading (Rasinski, 2016). Although the science of reading has been a significant topic surrounding the issue of improving literacy in schools, there is little focus on the teaching of fluency at the secondary level (Shanahan, 2021; Steinle, 2022; Wexler, 2008) and how fluency influences reader identity. This article seeks to explore this question through the lens of the dialogical self (Hermans, 2001). In this case study, three 11th grade students participated in a series of lessons targeting components of fluency-accuracy, speed, …
Epic Fantasy As A Postsecular Genre: The Stormlight Archive's Approach To Religion And Belief, Liz Busby
Epic Fantasy As A Postsecular Genre: The Stormlight Archive's Approach To Religion And Belief, Liz Busby
Theses and Dissertations
Epic fantasy as a genre has often been neglected due to its perceived conservative roots that clash with critical reading practices. This paper proposes that a postsecular lens may be more suitable to the critical study of epic fantasy and examines perhaps the most popular contemporary epic fantasy, Brandon Sanderson's Stormlight Archive, through a postsecular lens, First, the paper examines how the Stormlight Archive combines the premodern, fantastical worldview with modern and post-modern concerns to reinvigorate its exploration of the religious "big questions" through a renewed focus on the spiritual nature of the individual. Next, it examines how Sanderson presents …

This study investigates the effects of strengths-based peer coaching on novice ESL teacher well-being. Language teachers often face challenges in job security, teacher and financial status, institutional demands, and burnout. Novice ESL teachers especially face concerns about balancing teaching and student roles, building knowledge of the realities of teaching, and scaffolding a support system. The Virtues in Action Inventory of Strengths (VIA-IS) was used to identify participants' strengths, and teachers were assigned a peer to collaborate with who shared similar strengths. These teachers met with their assigned peer coach eight times throughout the semester to discuss ways of implementing strengths …
Focus On Form: Perceptions Of Portuguese Immersion Teacher When Implementing The Capa Model, Priscila Isabel Rebicki Prestes
Focus On Form: Perceptions Of Portuguese Immersion Teacher When Implementing The Capa Model, Priscila Isabel Rebicki Prestes
Theses and Dissertations
This study investigates Portuguese Dual Language Immersion (DLI) teachers' perceptions when implementing the CAPA Model, a structured Focus on Form Instruction (FFI) approach aimed at improving grammatical accuracy in content-based learning. While immersion students develop strong communication skills, research highlights persistent grammatical inaccuracies due to the emphasis on meaning-based instruction. The CAPA Model seeks to bridge this gap by integrating explicit grammar instruction, fostering metalinguistic awareness, and enhancing linguistic accuracy without detracting from content learning. Findings reveal that teachers recognize the model’s benefits but face challenges such as limited planning time, a lack of pre-adapted materials, and difficulties implementing all …
Investigation Of Temperature Control's Effects In Additive Friction Stir Deposition Of Al 7050-T7451, Jason Noah Glenn
Investigation Of Temperature Control's Effects In Additive Friction Stir Deposition Of Al 7050-T7451, Jason Noah Glenn
Theses and Dissertations
Additive Friction Stir Deposition (AFSD) is a friction stir based process that includes the addition of material extruding through a bore in the center of the rotating tool. The deformation of the material from the tool rotation and high pressures result in fully dense depositions printed at very high rates with forged like mechanical properties. While deposition properties of varying alloys have been increasingly published, little work has been done investigating control of the process and as with all additive processes, consistency and predictability are of significant concern before implementation can occur. One common control method implemented in Friction Stir …
The Most Beautiful Under Heaven: Selecting Views Of Modern China Through Travel Photography In Liangyou Huabao (The Young Companion), 1926-1937, Anne Marie Watson
The Most Beautiful Under Heaven: Selecting Views Of Modern China Through Travel Photography In Liangyou Huabao (The Young Companion), 1926-1937, Anne Marie Watson
Theses and Dissertations
Liangyou huabao (The Young Companion) was a prominent Chinese pictorial magazine, with 174 issues published monthly between 1926 and 1945. Liangyou entertained its Chinese audience with a variety of photographs documenting modern life. This thesis examines photographs of domestic travel photography in the magazine, arguing that editorial captions encouraged readers to associate images of China with allusions to traditional art and aesthetics. This occurred within a historical context where modernity was often associated with the pressures of Westernization, and where Chinese culture and civilization was sometimes characterized as outdated or irrelevant. By using travel photography to demonstrate how traditional culture …
The Right To Gender-Affirming Care, Justin J. Soulas
The Right To Gender-Affirming Care, Justin J. Soulas
Theses and Dissertations
As of recent, twenty-four states have enacted bans on gender-affirming care, restricting minors from accessing medically necessary treatment. Existing scholarship has begun to explore the profound impact of these bans on transgender youth, their parents or guardians, and the medical professionals who support them. However, the body of literature on this rapidly evolving issue remains limited. This thesis aims to fill that gap by offering a legal defense of gender-affirming care, grounded in judicial precedent. It argues that parental rights to make medical decisions for their children—recognized in constitutional jurisprudence—extend to decisions involving gender-affirming treatment. Additionally, it draws on anti-discrimination …

Sample Preparation And Acquisition Strategies To Improve Accessibility And Proteome Depth In Single-Cell And Low-Input Proteomics, Sara Madisyn Johnston
Sample Preparation And Acquisition Strategies To Improve Accessibility And Proteome Depth In Single-Cell And Low-Input Proteomics, Sara Madisyn Johnston
Theses and Dissertations
Proteins are responsible for important cellular functions and processes including regulation, structural integrity, signaling, transport, and immune functions. Proteomics directly identifies these proteins and enables deeper characterization of the dynamic cellular environment beyond the capabilities of genomics and transcriptomics. Single-cell proteomics further enhances this approach by capturing cellular heterogeneity, which bulk proteomics obscures due to averaging protein expression across large cell populations. Despite significant advances in single-cell proteomics, continued innovation is necessary to increase workflow accessibility and throughput, minimize peptide losses, and achieve comprehensive coverage of the proteome. This dissertation addresses these challenges by developing improved sample preparation methods, two-dimensional …
Eleanor Fortescue-Brickdale And The Best, The Worst, And The Betwixt: The Intertwined Women Of Arthurian Literature And Victorian Society, Hannah Johansson
Eleanor Fortescue-Brickdale And The Best, The Worst, And The Betwixt: The Intertwined Women Of Arthurian Literature And Victorian Society, Hannah Johansson
Theses and Dissertations
The late Victorian and early Edwardian artist Eleanor Fortescue-Brickdale’s illustrations and paintings have been largely marginalized in the larger world of Arthurian art and criticism. This thesis argues that her work, focused on the illustration Enid, Guinevere, and Vivien, is impactful in its exploration between Arthurian characters and Victorian women. Critiquing with a feminist ideology, Brickdale attempts to break down Victorian stereotypes on women by visually breaking down the socially congruent labels placed onto the women of Camelot. In doing so, she both critiques Victorian society and artistically argues for a much needed social reconstruction.
Navigating Light And Darkness: The Intersection Of Space, Faith And The Psyche In Ana Plácido’S Luz Coada Por Ferros, Alondra V. Ramirez Herrera
Navigating Light And Darkness: The Intersection Of Space, Faith And The Psyche In Ana Plácido’S Luz Coada Por Ferros, Alondra V. Ramirez Herrera
Theses and Dissertations
Ana Plácido (1831-1895) was a Portuguese writer whose literary contributions remain largely overshadowed by her infamous trial for adultery and her relationship with Camilo Castelo Branco. Despite societal constraints on female authorship in the nineteenth century, Plácido used literature as a means of self-expression, autonomy, and intellectual freedom. This thesis employs spatial theory to analyze her collection of texts Luz Coada por Ferros (1863), written during her imprisonment, to explore the interplay between physical confinement and artistic freedom. By examining the symbolic and psychological dimensions of space in her work, this study highlights how Plácido navigated themes of female agency, …

Aliases And Archetypes: A Spy's Dilemma In Tomás Nevinson, Silke Mckay Schnebly
Theses and Dissertations
Tomás Nevinson is the last novel by Javier Marías. The themes of betrayal, deceit, and doubt that are apparent in his other works continue here as well. The meandering and philosophical narration guides the reader through Tomás' quest for self-discovery. This article uses literary onomastics (the study of names, their meanings and origins) to peel back the layers of the various characters in order to reveal the archetypes they represent. Through analyzing the names in Tomás Nevinson, the reader may come to recognize the archetypes associated with the novel's characters while also recognizing how Tomás interacts with archetypal others in …

I Do, And I Will: Effectual Religiosity May Strengthen The Triad Chord Of Commitment To Promote Marital Flourishing For Women Of Faith, Tamara M. Chamberlain
Theses and Dissertations
Although religiosity often associates with marital satisfaction in sociological studies, very few studies have examined religiosity strengthening marital commitment for women of faith. This study used an exemplary sample to explore how religious, heterosexual married women view religion strengthening their marital commitment. Interviews from 196 highly religious couples provided insight into the following themes and subthemes (1) personal commitment, (a) decision to marry, (b) religious beliefs and practices, and (c) requires effort and sacrifice; (2) moral commitment, (a) sexual relations before marriage, (b) promises made before God, friends, and family, and (c) fidelity and feelings about divorce; and (3) structural …
Exploring The Associations Between Young Adults' Autistic Traits And Parental Differential Treatment, Madelyn Winder Bennett
Exploring The Associations Between Young Adults' Autistic Traits And Parental Differential Treatment, Madelyn Winder Bennett
Theses and Dissertations
The current study sought to identify autistic traits that may elicit parental differential treatment (PDT). Understanding these links are important because numerous studies have shown PDT to have negative implications for healthy development. Participants (recruited via Amazon Mechanical Turk) completed a survey assessing their experiences of parental differential treatment and their own autistic traits using the Autism Quotient (AQ) measure (Baron-Cohen et al., 2001). Participants were young adults ages 18-29 (M age = 25.4; 57% Female, 43% Male; 73% White, n = 739) who resided in the U.S. and had at least one living sibling. Using regression analysis, we examined …
Methamphetamine Effects On The Striatal Neuroimmune System, Hillary Adelaide Wadsworth
Methamphetamine Effects On The Striatal Neuroimmune System, Hillary Adelaide Wadsworth
Theses and Dissertations
Dopamine is thought of as the reward molecule of the brain, and while it does deal with reward, it is also associated with motivation and crucial for controlled movement. There are two main dopaminergic systems in the brain, the nigrostriatal system, which originates in the substantia nigra compacta and projects dopamine into the dorsal striatum; and the mesolimbic system, which originates in the ventral tegmental area and projects dopamine into the nucleus accumbens. While the mesolimbic dopamine system deals with motivation and reward, the nigrostriatal pathway underlies movement. Microglia are the immune cells of the brain and are incredibly dynamic. …
Mythology Of Autism: Pop Culture, Rhetoric, And Vaccines, Makenzi Strate
Mythology Of Autism: Pop Culture, Rhetoric, And Vaccines, Makenzi Strate
Theses and Dissertations
Myths are stories told to provide an explanation for the unknown, reflect cultural beliefs of populations that hold them, and lack scientific evidence to support these stories. Some myths, such as the myth that vaccines cause autism, are harmful toward the groups that they target. Popularized in 1998 with the publication of the Wakefield study, the myth that vaccines cause autism continues to spread and thrive today. To understand the widespread nature and detriments of belief in harmful myths such as this, I implement mythology rhetoric to examine how celebrity Jenny McCarthy utilizes elements of myth to persuade others to …
Teaching Information Synthesis In First-Year Writing: A Replication And Extension Study, Rachel M. Terry
Teaching Information Synthesis In First-Year Writing: A Replication And Extension Study, Rachel M. Terry
Theses and Dissertations
This study investigates the challenges and strategies associated with teaching information synthesis to first-year college students. Synthesis, a higher-order cognitive skill described as "knowledge-transforming," is critical for academic success and informed engagement in an information-saturated society. However, many students enter college with underdeveloped foundational reading and writing skills, compounded by declining literacy rates and the prevalence of fragmented digital content consumption. This study builds on prior research in composition, education, and information literacy to address three key questions: (1) How do students understand synthesis? (2) What strategies do students employ when attempting to synthesize information? (3) What instructional implications arise …

Language Choice And Russian Course Enrollment Among University Students, Emma Calderwood
Theses and Dissertations
University Russian enrollments have been steadily declining in the United States since 2009 (MLA, 2023). No research has been done to examine student motivation for studying Russian since long before the 2022 increase in conflict between Russia and Ukraine. This study surveys two groups of students at the university level: students enrolled in BYU 101-level language classes, and students enrolled in Russian classes at six universities in the United States. The findings report that the most common reasons students choose to take university Russian classes is because they have a general interest in the language, they want to travel to …
Inquiry-Style Planetarium Activities, Emma Rasmussen Groberg
Inquiry-Style Planetarium Activities, Emma Rasmussen Groberg
Theses and Dissertations
Introductory astronomy students often face challenges in exploring their own ideas and investigating astronomical phenomena due to the limitations of nighttime observation and weather conditions. Planetariums overcome these barriers by simulating the night sky, making it accessible during class sessions regardless of external conditions. This provides an opportunity to engage students in inquiry-based activities, where they are presented with a scenario and encouraged to use their own reasoning to reach conclusions. In this study, we implemented inquiry-based activities in PHSCS 127 using the planetarium as an investigative tool. We developed four activities designed to help students explore their ideas and …
Reconstruction Of Cad Models Into Single Trimmed Surfaces, Rebecca Rasmussen
Reconstruction Of Cad Models Into Single Trimmed Surfaces, Rebecca Rasmussen
Theses and Dissertations
Classical methods by which computer-aided design (CAD) geometries are represented for both design and analysis involve meshing. However, the current process of converting a CAD model into an analysis-suitable surface mesh for the automotive industry takes a significant amount of time and labor, results in a faceted representation of the original smooth geometry, and generates representations that are prohibitively expensive for use in high-order explicit dynamics computations. This research focuses on accurately and efficiently rebuilding given CAD surfaces or meshes, such as shell-like components of automotive vehicles, into smooth, single trimmed spline surface approximations (rather than typical piecewise-linear approximations), making …
