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 …

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 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 …

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 …

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 …

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.

Permanent gases and tars were measured in a fuel-rich (non-oxidising) environment in a flat flame burner (FFB). Permanent and light hydrocarbon gases were measured for the same fuels heated by a fire flame in ambient atmospheric conditions (oxidising environment). Log-ratio balances of the measured gases …

Religious Liberty: Natural Rights Or The Politics Of Conscience, Madeline Nielsen

Undergraduate Honors Theses

Religion Clause jurisprudence in the United States has long been a subject of debate. Vincent Phillip Muñoz and Steven D. Smith, two prominent scholars in the field, offer distinct perspectives on the interpretation and application of the Religion Clauses. Muñoz advocates for a natural rights construction, grounding religious liberty in the Founders' understanding of inalienable rights. In contrast, Smith analyzes the principle of religious liberty through reflecting upon how the Founders’, particularly James Madison, were influenced by the historical, philosophical, and theological development of the principle. This thesis conducts a comparative analysis of their viewpoints, focusing on their interpretations of …

The Negative Impacts Of Parentification On Adolescents: A Systematic Review, Reilly Reid Hawkins

Theses and Dissertations

While child abuse, maltreatment, and neglect are clear examples of the most maladaptive types of parent-child interactions (Borchet et al., 2022), there is considerable evidence for the damaging nature of parentification in terms of youth outcomes and parental/familial dysfunction. The research literature contains numerous studies related to parentification, but there is little research overtly demonstrating the systemic effects of parentification (Peris et al., 2008). It is imperative that researchers and clinicians learn more about the mechanisms involved in the parentification process. Therefore, this systematic review analyzed the research literature centered on both parentification and adolescent populations. This study assessed various …

3d Printed Mounts For Liquid Microdroplet Resonators, Parker A. Awerkamp

Theses and Dissertations

Liquid microdroplet resonators provide an excellent tool for optical studies due to their innate smoothness and high quality factors, but they can be difficult to control. By using 3D printed mounts to support the droplets, we can obtain precise control over the droplet geometries and positions. We here present our work with oil, water, and ice microdroplets, as well as tools required to enable their study. We first present methods for creating 3D printed mounts for oil microdroplet resonators. The mounts enable precise positioning of the droplets relative to a tapered optical fiber. The oil microdroplet resonators exhibited quality factors …

Congenital Heart Disease (CHD) is the most common birth defect, affecting approximately 1% of live births. This dissertation explores the genetic mechanisms underlying CHD, focusing on the T-box transcription factors Tbx2a and Tbx2b in zebrafish. Utilizing advanced bioinformatics techniques, we reconstructed the ancestral sequences of these genes to understand their evolutionary trajectory and functional divergence. Our analysis highlights the evolutionary conservation of the DNA-binding domain in tbx2a and tbx2b, suggesting its crucial role in maintaining correct gene expression patterns during development. We observed unique and shared amino acid substitutions in these proteins, indicating potential adaptive changes and conserved functions. Comparative …

Striking At The Root: A Categorization Of Dns Clients, Tyler Dean

Theses and Dissertations

The Domain Name System (DNS) root servers have provided a useful look into the DNS and internet ecosystems for decades. We present a categorization of clients querying DNS root servers. Using two clustering algorithms on DNS traffic sampled in 2020, we can predict the structure and volume of queries originating from different types of clients. Previous research has used unsupervised techniques to better understand DNS traffic patterns, but none have, to our knowledge, considered clients beyond those driven by queries from end users. By performing clustering on IP addresses rather than on individual queries, we are able to examine the …

Eugenics And Feminism: The Reflections Of Two Ideologies In The Reproductive Policies Of The Nazi Regime, The Reunification Period, And Present-Day Germany, Sydney Reil

Undergraduate Honors Theses

German abortion law is restrictive for a Western European nation of strong economic standing and with relatively liberal social policy. Additionally, Germany is one of few Western European nations without an embryopathy indication, which allows for exceptional abortions in cases of fetal defects. The law (as it stands in 2024), has been immeasurably shaped by two ideologies, eugenics and feminism, and by modern Germany’s consideration of both the ideologies themselves, and of how they influenced the reproductive policies of the twentieth century. The purpose of this study is to demonstrate the influences of eugenics and feminism on German reproductive law …

An Overview Of Contributing Frameworks To Culturally Sustaining Pedagogy, Sarai Clemente Soli

Theses and Dissertations

Culturally Sustaining Pedagogy (CSP) is a framework designed to help traditionally marginalized students. Other frameworks have previously tried to draw on culture to help students in similar ways. However, Paris (2012b) claimed that the word sustaining enclosed a meaning of maintaining and enhancing these students' language and cultural practices that no other frameworks did until that point. There is some confusion for educators and others about CSP since it is a newer framework and that there are many of these cultural frameworks analyzing similar concepts. Therefore, the purpose of this literature review was to examine these previous main frameworks that …

Long Distance Relationships: Connections Supporting Rural Science Teachers, Tracy Marie Poulsen

Theses and Dissertations

Research regarding the social professional networks among rural educators is sparse but indicates that rural educators have few supportive connections with other educators. Programs designed to increase the social networks of rural educators use characteristics of similarities in school assignments and geographic distances to place educators into groups for professional development and support, but rarely use technology extensively as a tool to overcome barriers of time, distance, and cost. In one intervention designed in part to increase the professional connections between rural science teachers, Technology Mediated Lesson Study (TMLS) was implemented in a group of rural science teachers. The before …

Theses and Dissertations

This thesis addresses the underrepresentation of indigenous Māori people in leadership positions and pursues the need to develop a Māori leadership framework aimed at empowering the next generation of indigenous people. Several frameworks have attempted to exhibit Māori leadership dynamics, each offering unique insights into the cultural and relational aspects of Māori leadership. However, existing frameworks often exhibit limitations in fully encapsulating the breadth of Māori leadership values and practices, necessitating the development of a comprehensive Māori leadership model independent of Western frameworks. Through an extensive review of existing literature and engaging with Māori experts, I synthesized key insights to …

Exploring The Effects Of Delayed Auditory Feedback On Speech Kinematics: A Comparative Analysis Of Monologue Speech And Tongue Twisters, Abbey Corinne Persons

Theses and Dissertations

This study investigated the effects of delayed auditory feedback (DAF) on speech kinematics during tongue twisters and monologues. Participants were 20 adults (10 men, 10 women) aged 18-29 with typical speech and hearing abilities. A smartphone app provided DAF latencies of 50 ms, 100 ms, and 150 ms. Kinematic measures were made of peak speed, stroke distance, and hull area for the tongue front, jaw, and lower lip under typical and the three DAF conditions. Results indicated that DAF significantly reduced peak speed and stroke distance for all articulators during tongue twisters (p < .01), with the effect magnitude increasing with longer delays. No significant DAF effects were observed in monologues (p > .05). Sex differences were noted, with women …

Information Geometric Approaches To Optimal Experimental Design And Reduced-Order Modeling In Ocean Acoustics, Jay C. Spendlove

Theses and Dissertations

This thesis demonstrates the application of information geometry to problems in underwater acoustics. Information geometry combines the fields of information theory and differential geometry by interpreting a multiparameter model as a Riemannian manifold in an ambient data space. Information geometry tools are especially powerful in context of problems of experimental design and model selection in ocean acoustics. The application area specifically considered in this research is geoacoustic inversion, where seabed parameter values are inferred from acoustical data. Chapter 2 contains a paper submitted to the Journal of Theoretical and Computational Acoustics, which introduces information geometry tools such as the model …

Documentation Of Norm Negotiation In A Secondary Mathematics Classroom, Michelle R. Bagley

Theses and Dissertations

While previous mathematics education research has shown that norms can change in mathematics classrooms, little research has closely documented the struggles, concessions, and compromises involved in the negotiation process. Negotiating norms is a complex process entailing deliberate teacher moves intended to promote norms, often met with misunderstandings or resistance from students. This thesis documented the negotiation process that occurred when a teacher attempted to require conceptual explanations from students who had not previously been accustomed to doing so. I recorded six days of instruction in a 9th grade algebra unit, transcribed the class discussions, and inferred norms "at play" for …

Six Connotations Of Sustainability In Civil And Construction Engineering: A Corpus Linguistics Study, Xiaomei Wang, Andrew South, Brett James Hashimoto, Clifton Farnsworth

Faculty Publications

This research explores the historic use of the concept of sustainability in civil engineering academic literature and identifies its conceptual evolution and connotative treatment over the last 40 years. We find that academic research addressing sustainability is exponentially increasing and that the focus on sustainability is enlarging from a primarily environmental perspective to include more social elements. Additionally, we propose a set of six connotations of sustainability: assessment, progress, permanence, abstractness, multidimensional, and intersectional. These connotations provide conceptual clarity for academics and practitioners in better-defining sustainability objectives and measuring outcomes. These connotations also promote more efficient collaboration with other necessary …

Ready, Set, Grow: From Micelles To Giant Vesicles Via Biocatalytic Activation, Nicholas P. Bair, Qinyu Zhu, Bryon A. Staynings, Douglas R. Tree, Walter F. Paxton

Faculty Publications

Controlling physicochemical processes that drive changes in supramolecular aggregates is an important objective toward creating artificial soft micro- and nanomachines. Previous research explored the morphology control of membrane-based materials subjected to externally imposed chemical stimuli. Here, we modulate the microscale morphology of pH-responsive assemblies by using biocatalysis to internally generate changes in global pH. Catalytic reactions offer flexibility in the mechanism and rate at which stimuli are introduced to responsive assemblies, ultimately enabling precision and control over size and morphology. We observed, by dynamic light scattering and fluorescence microscopy, substantial microscale differences between assemblies subjected to manually titrated pH changes …
