Hybrid Bermudagrass Drought Tolerance In A Cool-Season Climate, Ashley J. Beazer Apr 2025

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 Apr 2025

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 Apr 2025

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 …

Focus On Form: Perceptions Of Portuguese Immersion Teacher When Implementing The Capa Model, Priscila Isabel Rebicki Prestes Apr 2025

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 Apr 2025

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 Apr 2025

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 …

Sample Preparation And Acquisition Strategies To Improve Accessibility And Proteome Depth In Single-Cell And Low-Input Proteomics, Sara Madisyn Johnston Apr 2025

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 Apr 2025

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 Apr 2025

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, …

Assessing Innovations In Wildlife Monitoring: Estimating Abundance And Inferring Parturition Of Ungulates With Technology, Elicia Cotcher Apr 2025

Assessing Innovations In Wildlife Monitoring: Estimating Abundance And Inferring Parturition Of Ungulates With Technology, Elicia Cotcher

Theses and Dissertations

Enhancements in technology are creating opportunities for novel methods of wildlife monitoring. Traditional methods of wildlife monitoring are often costly or time-consuming, and new technological advancements such as remote cameras and GPS collars are creating opportunities for exploration as these technologies become more accessible and reliable. We sought to assess the efficacy of two novel methods of ungulate monitoring. The first is an abundance estimation method using remote cameras termed Instantaneous Sampling (IS). IS seeks to estimate abundance using time lapsed remote cameras on a population of unmarked individuals. Our goal was to compare IS estimations against the true observed …

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 Apr 2025

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 Apr 2025

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 …

Porous Hierarchically Ordered Hydrogels Demonstrating Structurally Dependent Mechanical Properties, Elisabeth C. Lloyd, Sujata Dhakal, Shahrouz Amini, Rami Alhasan, Peter Fratzl, Douglas R. Tree, Svetlana Morozova, Robert J. Hickey Apr 2025

Porous Hierarchically Ordered Hydrogels Demonstrating Structurally Dependent Mechanical Properties, Elisabeth C. Lloyd, Sujata Dhakal, Shahrouz Amini, Rami Alhasan, Peter Fratzl, Douglas R. Tree, Svetlana Morozova, Robert J. Hickey

Faculty Publications

While hierarchical ordering is a distinctive feature of natural tissues and is directly responsible for their diverse and unique properties, efforts to synthesize biomaterials have primarily focused on using molecular-based approaches with little emphasis on multiscale structure. Here, we report a bottom-up self-assembly process to produce highly porous hydrogel fibers that resemble extracellular matrices both structurally and mechanically. Physically crosslinked nanostructured micelles form the walls of micrometer-sized water-rich pores with preferred orientation along the fiber direction. Low elastic moduli (< 1 kPa), high elasticity (extending by more than 12 times the initial length), non-linear elasticity (e.g., hyperelasticity), and completely reversible extension are derived from unevenly distributed strain between the micrometer-sized pores and the polymer chains, which is reminiscent of cellular solids. Control of the material microstructure and orientation over many orders of magnitude (e.g., nm–μm), while holding the nanostructure constant, reveals how the multiscale structure directly impacts mechanical properties.

Methamphetamine Effects On The Striatal Neuroimmune System, Hillary Adelaide Wadsworth Apr 2025

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 Apr 2025

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 Apr 2025

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 …

Inquiry-Style Planetarium Activities, Emma Rasmussen Groberg Apr 2025

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 Apr 2025

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 …

The Influence Of Leaders And Managers In Commercial Construction, Samuel F. Merrill Apr 2025

The Influence Of Leaders And Managers In Commercial Construction, Samuel F. Merrill

Theses and Dissertations

This research explores how the distinct traits of leadership and management influence supervisory effectiveness and employee experiences in Utah's commercial construction sector. While leadership and management are often conflated, this study draws on foundational literature that defines leadership as people-centered, visionary, and empowering. In contrast, management is characterized as results-driven, process-oriented, and focused on control. Using survey data from 95 individuals working in commercial construction, the study evaluates how supervisors with leadership or managerial characteristics are perceived by their teams. Supervisors were categorized based on observable behaviors selected by respondents, distinguishing leadership traits from managerial traits. Supervisors identified as leaders …

Reclaiming Identity: Miné Okubo's Self-Portraiture And Authorship In Citizen 13660, Caroline E. Johnson Apr 2025

Reclaiming Identity: Miné Okubo's Self-Portraiture And Authorship In Citizen 13660, Caroline E. Johnson

Theses and Dissertations

In this thesis, I argue that Miné Okubo's repeated self-portraiture in Citizen 13660 asserts her authority of the soul author of the text, forcing her reader to acknowledge the perspective in which the story is being told. Through the images of herself, she makes clear the fact that the story is filtered through her personal experience, rather than the widely accepted understanding that the novel is a universal story. While the written account strives for a sense of objectivity, the images of Okubo, especially when analyzed through the context of her contemporaries, including comics and photographers, shows how her work …

Assessing The Effectiveness Of Aging Techniques On Cloning Fpga-Based Configurable Ring Oscillator Pufs, Jonathan Thompson Apr 2025

Assessing The Effectiveness Of Aging Techniques On Cloning Fpga-Based Configurable Ring Oscillator Pufs, Jonathan Thompson

Theses and Dissertations

Field Programmable Gate Arrays (FPGAs) are reconfigurable devices that are used in industries that often require increased security. Physically unclonable functions (PUFs) are a security primitive used on FPGAs for device authentication and key generation. However, the output of a PUF can be susceptible to changes in the environment, such as voltage and temperature, as well as changes in device performance that occur due to transistor aging. Previous work has shown that it is possible to induce targeted accelerated aging in order to intentionally change a PUF response, even to the point of cloning one PUF to behave like another. …

Organismal Classification And The Phylogenetic Tree: Improving Its Teaching Using Decision-Based Learning, Melissa Cavan Apr 2025

Organismal Classification And The Phylogenetic Tree: Improving Its Teaching Using Decision-Based Learning, Melissa Cavan

Theses and Dissertations

For a lot of students, learning biology is like learning a new language. There are new terms and concepts that a lot of new students have never heard of. Evolution is the cornerstone for understanding biology, yet it is one of the more misunderstood topics. In combination with learning new terms and concepts some students come in with preconceived ideas about evolution or misunderstandings about how evolution and the phylogenetic tree work. The research indicates instructors attempting active learning techniques to increase understanding of the phylogenetic tree with mixed results, where there appears to be some improvement but nothing significant. …
