Left-Hand Technique And The Limits Of The Possible, Ricardo Iznaola

Soundboard Scholar

This article conceptualizes classical guitar left-hand technique through a physiomechanical framework that places coordinated movement—particularly shifting—at the center of technical practice. Challenging traditional positional doctrines that privilege static hand forms and digital independence, the author argues that such approaches often disregard the functional anatomy of the limb, resulting in inefficiency, unnecessary tension, and potential injury.   Advancing the principle that form must follow function, the study proposes shifting as the fundamental technical category governing all left-hand procedures. A systematic typology—interpositional, intrapositional, and compound shifting—serves as the basis for analyzing arm-wrist-hand coordination across diverse technical contexts, including extensions and contractions, barrés, slurs, …

Uncertainty-Aware Estimation, Planning, And Control For Tracking Multiple Drifting Patches In Flow Fields, Daniel O. Akanji, Krishnanand N. Kaipa, Cong Wei

Mechanical & Aerospace Engineering Faculty Publications

In this study, we present a replay-based framework for uncertainty-aware persistent tracking of multiple advected surface patches using an autonomous marine vehicle operating in spatiotemporal-varying currents. The method combines three components: local flow estimation, covariance-aware patch-boundary propagation with intermittent boundary fusion, and mission-level scheduling over multiple patches. Each patch is represented by a polygonal boundary, whose vertices are propagated through the estimated flow field while carrying per-vertex covariance, thereby quantifying uncertainty growth during advection. A flow-aware gain-scheduled linear quadratic regulator (LQR) was designed to shape the desired surge speed to take advantage of favorable currents. When the vehicle services a …

Impacts Of Teacher Leadership On K-12 Teachers, School Communities, And Students, Jordan Birkeland

All Electronic Theses and Dissertations

In K-12 education today, teachers are frequently being called upon to lead. Not only are they receiving increasingly more responsibilities, but they are relied upon more to support students and fellow staff in a variety of ways. Therefore, it is important to understand if the development and utilization of teacher leadership is a necessary method to provide schools with a way to support educators and other stakeholders. This literature review explores how teacher leadership is defined and practiced relative to the prevailing leadership models used in K-12 education, and identifies the impacts of teacher leadership on grades K-12 teachers, school …

Objective Assessment In Experiential Learning Contexts, Lily M. Brutger

All Electronic Theses and Dissertations

Experiential learning is widely recognized as a powerful approach to education; however, empirical evidence demonstrating its effectiveness remains limited. This gap in the literature is due less to the value of experiential learning itself than to the challenges of assessing learning within experiential contexts. Drawing on the foundational experiential learning theories of Kolb (1984) and Joplin (1981), as well as contemporary research on assessment validity and practice, this paper examines the relationship between assessment and experiential learning. It argues that purposeful, objective assessment is essential for maximizing student learning and supporting the credibility of experiential education. The paper synthesizes current …

Reading Comprehension And Secondary Education, Noah W. Hillman

All Electronic Theses and Dissertations

This literature review is designed to look at how reading takes place in a classroom setting and how teachers might support students as they read - primarily in secondary education (middle and high schools). Students at all levels need scaffolding and support to be successful when interacting with challenge texts. The instructional role of the teacher as it pertains to reading comprehension impacts the success of students’ skills. The literature review examines teacher practices and instructional strategies that can be used to support students’ reading comprehension at the secondary level.

Ai-Supported Socratic Questioning And Instructional Scaffolding: Effects On Student Comprehension, Reshma John

All Electronic Theses and Dissertations

This literature review examines how the intentional use of artificial intelligence (AI) designed for Socratic questioning and instructional scaffolding affects students' comprehension of course content. The literature suggests that AI is most likely to support comprehension when it prompts students to explain their reasoning, respond to guided questions, reflect on their understanding, and receive support adapted to their needs. In contrast, systems that primarily provide direct answers may encourage overreliance and mask gaps in students' understanding. Overall, the educational value of AI depends less on its availability and more on how it is designed and implemented.

Teaching Primary Sources To Increase Engagement And Build Literacy, Lindsey L. Beaulieu

All Electronic Theses and Dissertations

This thesis reviews the use of primary sources in education. This literature review analyzes 30 articles regarding educators’ use of primary sources. There are four major themes within the articles: literacy with primary sources, engagement with primary sources, comprehension with primary sources, and examples of primary source units or lessons. While specific teaching topics vary, the overall consensus is that primary sources can help students’ skills with literacy, engagement, and comprehension. A main topic among the research is the educators’ understanding of scaffolding, pre-teaching, choosing primary sources, and re-using the primary sources, to be able to teach students effectively.

Meconium Metal Concentrations And Infant Temperament And Development, Fiona Fogarty

Dissertations and Theses

BACKGROUND: Prenatal exposure to metals poses significant health consequences for early childhood development. Understanding the factors influencing metal concentrations that infants are exposed to in-utero is crucial for developing targeted interventions, particularly when maternal characteristics and environmental factors, may contribute to varying levels. Meconium offers insight into in-utero exposures for the developing infant, and the effect of each individual metal may be mediated or exacerbated by another and therefore should be studied in the context of a mixture. The effect of metal mixture exposure, as measured in meconium, on milestone and temperament outcomes has yet to be determined.

Testing The Influence Of Increased Predation On The Evolution Of Morphological Coloration Plasticity In Trinidadian Killifish (Anablepsoides Hartii), Alyssa M. Laux

Biology Theses

The ability to camouflage is a widespread trait in both vertebrates and invertebrates that enhances survival in risky environments. The ability of organisms to respond to shifts in environmental conditions and change color is a conspicuous example of camouflage. Such coloration plasticity can occur rapidly (seconds to minutes) versus longer periods of time (days to months). There are numerous examples of physiological coloration plasticity (short-term) and morphological coloration plasticity (long-term). Yet, there are few tests of the conditions that drive the evolution of physiological vs. morphological coloration plasticity. In this study we use Trinidadian killifish (Anablepsoides hartii) as …

The Role Of Academic Vocabulary Instruction In Supporting Secondary English Learners' Science Proficiency, Chue Seng Her

All Electronic Theses and Dissertations

This literature review examines the extent to which academic vocabulary instruction influences secondary English learners’ (ELs’) science proficiency. Science learning requires students to interpret complex texts, engage in academic discourse, and construct evidence-based explanations using discipline-specific language, which may present challenges for ELs. This review provides an overview of research on language demands in science and instructional approaches that support vocabulary development. Findings indicate that academic vocabulary plays a critical role in students’ ability to comprehend scientific content, participate in discourse, and communicate reasoning effectively. Instructional approaches such as explicit vocabulary instruction, scaffolding, discourse-based strategies, reciprocal teaching, cognitive strategy instruction, …

Economic Exchange And Relational Work In Doubled-Up Households, Hope Harvey

Sociology Faculty Publications

Doubling up, or sharing a home, is an increasingly common way that families make ends meet. Drawing on over 170 in-depth interviews with 60 parents, I ask how doubled-up household members understand and contest their economic relationships. I show that the success of intra-household economic exchange depends not only on the amounts exchanged, but also the shared meanings behind these exchanges. Given the lack of institutionalized expectations guiding doubled-up household relationships, household members draw on competing norms, framing the household as either a solidarity unit or a series of independent nuclear family units. Although disagreement over economic relationships is common, …

Perceived Adolescent Insecure Attachment With Mothers And Fathers, Helena Pipová, Martin Dolejš, Jaroslava Suchá, Alexander T. Vazsonyi

Sociology Faculty Publications

The aim of this study was to test relationships between adolescent insecure attachment (anxious and avoidant) with mothers and fathers and three outcomes: food addiction, eating disorders, and weight status, in a large multi-regional sample of Czech adolescents. Anonymous, self-reported data were collected from 3,677 adolescents (1,688 boys, 45.9% and 1,989 girls, 54.1%). Both anxious and avoidant attachment with mothers were positively associated with food addiction (p <.001) and eating-disorder risk (p <.001). Importantly, avoidant attachment with fathers uniquely and additively explained variance in both food addiction (p <.001) and eating-disorder risk (p =.003), after controlling for maternal attachment. Weight status was unrelated to attachment and was predicted by sex and parental education only. Study findings highlight the salience of insecure attachment with both mothers and fathers for food addiction and eating disorders among adolescents and identify the parental relationship as a key potential preventative strategy.

The use of Photovoice methods to identify and address public health challenges has evolved since this participatory action research method’s inception in the 1990s. However, there is a notable lack of research on the dissemination of Photovoice findings to promote community action and change. This study evaluates audience and Photovoice participants’ experiences of dissemination events presenting the results of 21 Photovoice projects that supplemented the HEALing Communities Study (HCS), a multistate community-based study of strategies to reduce opioid overdose deaths. The Photovoice projects captured the perspectives of people with lived experience of substance use disorder and front-line providers regarding their …

Suicide Stigma In A Cross-Cultural Context: Comparison Between Mexican And Mexican American Communities., Robin E. Gearing, Micki Washburn, Kathryne Brewer, Luis R. Torres-Hostos, Pedro Isnardo De La Cruz, Miao Yu, Natalia Giraldo-Santiago, Alberto Cabrera, Adelaido Garcia Andres

School of Social Work Faculty Publications

Suicide and suicide-related stigma are serious public health issues affecting Latine communities and often serve as a barrier to help-seeking Mexicans and Mexican Americans experiencing mental health concerns. Despite this, there are still gaps in our understanding of how suicide stigma specifically impacts Latines of Mexican heritage. While Mexicans and Mexican Americans share many familial, cultural, and religious values, their exposure to different societal norms may shape distinct perceptions of suicidal ideation and mental health. To better understand suicide-related stigma in these communities, we conducted a community-based survey with 248 Mexican Americans in Houston and 203 participants in Mexico City …

The Digital In The Library: Finding The Mutually Beneficial Synergy, James M. Donovan

Law Faculty Books and Chapters

With the value of access to digital resources abundantly demonstrated during the COVID-19 lockdown, enthusiasm for the format is reaching new heights. This chapter counsels restraint, rebutting the argument that skepticism concerning the wide adoption of digital materials into the library is due merely to nostalgia by anti-technologists for a now-bygone age. Despite their obvious usefulness in certain situations, patrons have not responded well when libraries propose to discard legacy print collections in favor of transient electronic formats.To explain this rejection, this chapter argues that libraries are built upon principles of collection development and organization of materials in order to …

Mechanical Property Evaluation Of Paper Die Materials In Explosive Forming, Higa Yoshikazu, Kadena Hisashi, Shimojima Ken, Iyama Hirofumi

ASEAN Journal on Science and Technology for Development

This study investigates the feasibility of using paper materials as substitutes for molds in explosive forming by systematically evaluating their mechanical properties. Tensile tests were conducted on three paper types differing in thickness and internal fiber structure, using a custom-designed gripping tool. Specimens were prepared in multiple orientations to account for anisotropic behavior. Results indicate that coated paper, exhibiting the highest specific tensile strength and energy absorption per unit basis weight, is the most suitable for formability. In contrast, thick paper, characterized by the lowest specific tensile energy absorption, offers the best dimensional accuracy. Anisotropy was observed in matte and …

Face2cam: A User-To-Webcam Distance Estimation Image Dataset, Yixuan Zhai, Arryn Robbins

Psychology Faculty Publications

Estimating the distance between a user and their device’s camera is important for tasks such as gaze-aware interaction, adaptive interface scaling, and accessibility tools. Specialized depth sensors are effective but rarely available in everyday computing devices; by contrast, webcams are ubiquitous yet lack native distance information. To advance accessible distance-aware computing, we present Face2Cam, an openly available dataset of webcam images annotated with user-to-camera distances. Thirty-six adults were photographed under controlled variation of head orientation, gaze direction, and illumination, yielding 3,240 labeled images spanning distances from 30–80 cm. As a baseline, we trained a convolutional neural network as a lightweight …

Effect Of Mid-Range Ultraviolet Light On Avian Embryonic Development, Keelie Hughes

Biology Theses

While it is a known fact that specific environmental conditions must be met to ensure proper embryonic development, the impact of changes in this delicate balance is unclear. Ultraviolet (UV) light has a narrow range of effectiveness in mature tissue, where too little can hinder molecular signaling and too much can cause damage to genetic material. This study exposed in ovo chicken embryos in the preliminary stages of development to mid-range UV radiation to examine developing embryo and tissue morphology using anthropometric methods and comparing proliferative cells among embryos exposed to varying doses of UV light. Additionally, quantitative polymerase chain …

Integrated Thermal, Energy, And Structural Performance Assessment Of A Novel In-Service Shallow Geothermal Bridge Deicing System, Alireza Fakhrabadi

Civil Engineering Dissertations

Understanding the performance of bridge deck deicing systems under winter weather conditions is important for improving transportation safety and reducing long-term deterioration of bridge infrastructure. Bridge decks are more vulnerable to icing than ground-supported pavements because they are exposed to ambient air, wind, and radiation from multiple directions, while they do not receive thermal support from the underlying soil. Conventional deicing methods, especially chloride-based salts, can reduce ice formation in the short term, but repeated application may accelerate reinforcement corrosion, concrete damage, and environmental concerns. Therefore, shallow geothermal energy has been considered as a sustainable alternative for bridge deck deicing …

To Become More Fully Human, Mandy Luszeck, Rachel Knecht

On September 10th, 2025, I joined a club I never wanted to join—the club of teaching at a school where an act of senseless gun violence took an individual’s life during hours meant for open dialogue and education. On the same day, the teachers at Evergreen High School also joined that club.

Engagement Is Not A Checklist, Michael S. Bowden

The Utah English Journal

A Familiar Classroom Scene

A teacher stands at the front of her classroom, mid-lesson, and scans the room to check for understanding. She sees what many teachers recognize in their classrooms every day: a sea of students, each seemingly in a different place. In the projector’s glow, she sees a few students intently taking notes on the lesson; a couple are scratching doodles on their page, one is staring straight ahead but not really interacting, and she can hear two more click-clacking on their keyboards as they are looking at something on their Chromebooks.

Four Feedback Tips For A Fifth Year, Annika Nielson

The Utah English Journal

Over the past four years of teaching writing, I’ve picked up a few lessons. One is that students will wait until the very last minute to submit a piece, no matter how much in-class drafting time I build into the schedule. Another is that many students see writing as big, bad, and boring: they have been trained to think that their writing will be corrected with red pens and long lists of mistakes.
