The Interplay Of Spin, Charge, And Heat: From Metal/Insulator Heterostructures To Perovskite Bilayers, Sam M. Bleser

Electronic Theses and Dissertations

In this dissertation begin with an investigation of non-local spin transport in an amorphous germanium (a-Ge) sample via the inverse spin Hall effect (ISHE). In that study we show that commonly used techniques such as differential conductance and delta mode of a paired Keithley 6221/2182a for non-local resistance measurements can lead to false indicators of spin transport. Next, we turn out attention to a thickness dependent study in thermally-evaporated chromium (Cr) thin films on a bulk polycrystalline yttrium-iron-garnet (YIG) substrate. This project analyzed the spin transport in the Cr films versus thickness via the longitudinal spin Seebeck effect (LSSE). This …

Breaking Point: An Examination Of The Factors And Motivators That Determine Whether A Teacher Will Stay In The Classroom Or Choose To Leave The Profession, Katherine Treloar

Electronic Theses and Dissertations

Teachers are quitting the profession in droves, leaving classrooms empty or overcrowded. As a result, students are receiving a sub-par education from unexperienced or underqualified teachers (Watling et al, 2010). Retaining teachers for more than five years is no small feat. Teachers face unrealistic expectations, chronic high stress, and mental and physical health problems that lead to widespread burnout. However, some teachers are able to overcome these obstacles and stay in the profession for long periods of time (Buric & Penzic, 2019). This study identifies the internal motivations and external factors that influence teacher job satisfaction and describes how those …

Childhood Discipline Disparities For African American And Latinx Students, Cierra Townsend

Electronic Theses and Dissertations

African American and Latinx students are disproportionality impacted by punitive discipline models including suspensions, detention, and expulsions. This disproportionality removes students from the education setting creating adverse social emotional, academic, and economic outcomes. Students who are suspended and expelled are more likely to have contact with the juvenile justice system and or to be pushed out of school into alternative settings. Therefore, punitive discipline leads to increased school-based pathways to the juvenile justice system (SPJJ), also known as the school the prison pipeline (STPP). Despite knowledge of these adverse outcomes, schools continue to utilize punitive discipline practices. School psychologists are …

A Time To Create Change: A Case Study Of Culturally Relevant Education, Colleen Kopay

Electronic Theses and Dissertations

An opportunity gap exists in the United States school system where students of color score lower on standardized tests and have fewer opportunities than their white counterparts. Culturally Relevant Education (CRE) theory attempts to close this gap, and is defined by Gloria Ladson-Billings (1995) as

Pedagogy that rests on three criteria or propositions: (a) Students must experience academic success; (b) students must develop and/or maintain cultural competence; and (c) students must develop a critical consciousness through which they challenge the status quo of the current social order (p. 160).

In short, CRE is the use of culture, rigor, and critical …

You Have To Play To Win: Value Capture In Open Innovation, John T. Pritchard

Electronic Theses and Dissertations

Despite the extensive research on open innovation, debate remains on the relationship between open innovation and firm performance. No consensus exists on the measures of performance and the mechanisms that enable value capture remain largely unexplored. This dissertation addresses these issues in two parts. First, a theoretical model based on knowledge flows is introduced. Knowledge is at the heart of open innovation and this dissertation examines the role that external and internal knowledge play in firm performance outcomes. It integrates the dynamic capability view and open innovation literature to build a framework and set of arguments on how knowledge is …

The Use Of Regularization To Detect Racial Inequities In Pay Equity Studies: An Empirical Study And Reflections On Regulation Methods, Christopher M. Peña

Electronic Theses and Dissertations

Since the late 1970s, multiple linear regression has been the preferred method for identifying discrimination in pay. An empirical study on this topic was conducted using quantitative critical methods. A literature review first examined conflicting views on using multiple linear regression in pay equity studies. The review found that multiple linear regression is used so prevalently in pay equity studies because the courts and practitioners have widely accepted it and because of its simplicity and ability to parse multiple sources of variance simultaneously. Commentaries in the literature cautioned about errors in model specification, the use of tainted variables, and the …

A View From Within: Timbre As An Analytical Tool In Contemporary Viola Music, Ash Mach

Electronic Theses and Dissertations

Timbre is an elusive musical parameter that musicians, physicists, and cognitive scientists have been grappling with for centuries. While timbre can roughly be defined as an auditory attribute that distinguishes one tone color from another, this definition does not capture the complexities of sound and our perceptions thereof. Research on timbre has flourished since the 20th century, however, timbre studies has largely gone unnoticed within the viola community. This study, “A View from Within,” helps close the gap between timbre studies and viola repertoire scholarship by presenting analyses of three pieces from the 20th and 21st centuries through a timbre …

Representing The Mixed Plate: Involving Descendant Communities And Kānaka Maoli In Hawai’I Plantation Museums, Amanda Ku’Ualohalanileimakamae Lane

Electronic Theses and Dissertations

This thesis explores the ways that the involvement of diverse stakeholders at Hawai’i plantation museums affects representations of Hawai’i’s plantation history. Plantations in Hawai’i had a direct colonizing effect on Kānaka Maoli (Native Hawaiians), displacing them from their lands, replacing them with immigrant laborers, and putting into motion the chain of events that led to Hawai’i’s annexation in 1898. The current-day population in Hawai’i continues to reflect these significant changes in the society and culture of the islands. Hawai’i’s plantation museums traverse topics of labor, immigration, indentured servitude, and colonization. Simultaneously, these museums advance stories of perseverance, celebration, and multiculturalism. …

Enhancing Search Engine Results: A Comparative Study Of Graph And Timeline Visualizations For Semantic And Temporal Relationship Discovery, Muhammad Shahiq Qureshi

Electronic Theses and Dissertations

In today’s digital age, search engines have become indispensable tools for finding information among the corpus of billions of webpages. The standard that most search engines follow is to display search results in a list-based format arranged according to a ranking algorithm. Although this format is good for presenting the most relevant results to users, it fails to represent the underlying relations between different results. These relations, among others, can generally be of either a temporal or semantic nature. A user who wants to explore the results that are connected by those relations would have to make a manual effort …

Changes In Balance With Brain Inflammation: Sensitivity In Dual Motor Mechanisms, Hannah Mcdade

Electronic Theses and Dissertations

Concussion assessment in athletes has gained prominence due to potential long-term consequences of traumatic brain injuries. Evaluating balance alterations is crucial for understanding post-injury motor control strategies. This study introduces a novel approach to understanding center of pressure (COP) dynamics during quiet stance tasks for assessing balance impairments in athletes recovering from concussion. Concussed athletes often experience impaired motor function and cognitive deficits, increasing the risk of orthopedic injury. Traditional balance assessments focus on total COP (COPt), overlooking nuanced hip and ankle mechanisms. This research investigates COP variations between constant loading (COPc) and variable loading (COPv) signals in concussed athletes …

Using Black feminist thought and sista circle methodology, this study introduced narratives from five Black women who came together to comprise a collective standpoint. To better understand this phenomenon, study participants completed individual interviews, two Sista Circles, and one reflection survey. Three main findings were the interconnectedness of Black Greek-letter organizations and Black subcommunities at predominantly white institutions, the nonlinear nature of the Black sorority rejection experience, …

Likeness In Utopia: Situation And Metaphor From Thomas More To Edward Bellamy, Sage Rachmiel Bard Gilbert

Electronic Theses and Dissertations

As a literary genre, utopia is notably didactic. It seeks to teach desire and to educate hope. As such, utopia provides a unique site to examine the way metaphor and imagination enable one to be convinced, and the way those same elements facilitate misunderstanding. Following the theorization of Ernst Bloch, the goal of critiquing these literary utopias is not to reject hope but, rather, to educate our own daydreams, to learn and move forward. These chapters examine didacticism and the development of colonial metonymy in Thomas More’s Utopia, the way metaphor operates through time in Edward Bellamy’s Looking Backward: …

Electronic Theses and Dissertations

The Peace Corps is a transformative experience for many young Americans. The majority of volunteers have worthwhile services they remember fondly; however, these experiences are not always positive. The Peace Corps is a Cold War initiative that uses soft power techniques to further American exceptionalism, capitalism, and the modernization theory of development. The goal of this project was to understand what factors led to the negative experiences of Peace Corps Volunteers. I conducted an ethnography that focused on online communities, semi-structured interviews, Peace Corps memoirs, and news articles to understand Peace Corps Volunteers’ experiences and the organizational culture where they …

Safest Kid (A Sexual Assault Framework In Education To Support Trauma In Kids With Intellectual Disability): Delphi Study Development Of A Model And Utilization, Ashley M. Hudson

Electronic Theses and Dissertations

There is a grave need for additions to the school psychologist’s toolbox to support students with intellectual disability (ID) and sexual trauma. These children are especially vulnerable to adverse life experiences overall and are at a particularly high risk of experiencing sexual abuse and resulting trauma. Children with ID are less likely to have their trauma symptoms identified by those around them, as symptoms do not always present in the same way as their neurotypical peers and trauma symptoms are more likely to be grouped into the rest of their disability through diagnostic overshadowing. Additionally, individuals with ID are at …

Quantitative, Photocurrent Multidimensional Coherent Spectroscopy, Adam Halaoui

Electronic Theses and Dissertations

Multidimensional coherent spectroscopy (MDCS) is a quickly growing field that has a lot of advantages over more conventional forms of spectroscopy. These advantages all come from the fact that MDCS allows us to get time resolved correlated emission and absorption spectra using very precisely chosen interactions between the density matrix and the excitation laser. MDCS spectra gives the researcher a lot of information that can be extracted purely through qualitative analysis. This is possible because state couplings are entirely separated on the spectra, and once we know how to read the data, we can see how carriers transport in the …

Electronic Theses and Dissertations

This dissertation focused on modeling specimen-specific soft tissue structures in the context of joint replacement surgery. The research addressed four key aspects. The first study involved developing a workflow for creating finite element models of the hip capsule to replicate its torque-rotational response. Experimental data from ten cadaveric hips were used to calibrate the models, resulting in improved accuracy and relevance for surgical planning and implant design. The second study tackled the challenge of expediting the calibration of mechanical properties of the hip capsule to match patient-specific laxities. A statistical shape function model was proposed to generate patient-specific finite element …

Digital Twins Of The Living Knee: From Measurements To Model, Thor Erik Andreassen

Electronic Theses and Dissertations

Modern medicine has dramatically improved the lives of many. In orthopaedics, robotic surgery has given clinicians superior accuracy when performing interventions over conventional methods. Nevertheless, while these and many other methods are available to ensure treatments are performed successfully, far fewer methods exist to predict the proper treatment option for a given person. Clinicians are forced to categorize individuals, choosing the best treatment on “average.” However, many individuals differ significantly from the “average” person, for which many of these treatments are designed. Going forward, a method of testing, evaluating, and predicting different treatment options' short- and long-term effects on an …
