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 …

Cross-Institutional Collaboration And Exhibit Making: “On The Gold Mountain: Chinese Mining History And Heritage Of Idaho” At The Idaho Museum Of Mining And Geology, Jordan Kathleen Bennett

Electronic Theses and Dissertations

The Gold Rush, which brought many new immigrant communities to the American West, made a permanent impact on American culture by prompting the development of many Western towns. However, the Chinese immigrant mining population in the Boise, Idaho area has had little museum representation despite the more than 300,000 Chinese people who emigrated to the US between the 1840s and 1880. To rectify this, the Idaho Museum of Mining and Geology (IMMG), in collaboration with members of the Payette National Forest, the Asian American Comparative Collection, Boise State University/US Army Corps of Engineers, and the University of Denver, developed an …

Finite Element Analysis Of Thermal-Mechanical Instabilities In Nonmetallic Friction Composite Material, Joseph-Shaahu Shaahu

Electronic Theses and Dissertations

Thermal-mechanical instability (TMI) has been a research topic of interest as it focuses a lot on transportation systems. Thermal-mechanical instability was first noticed in railway and experimentally studied with a pin-to-pin or pin-to-surface setup of sliding contact. The topic has been extended into brakes and clutches which are two of the most common sliding systems most susceptible to thermal buckling and thermoelastic instability (TEI), where thermal buckling and thermoelastic instability are two sub-categories of thermal-mechanical instability. Thermal-mechanical instability is an ongoing research to better understand the phenomenon and the limits at which such instability occurs. This work delved into the …

Assessment Of Method Effects Of Keying And Wording In Instruments: A Mixed-Methods Explanatory Sequential Study, Lin Ma

Electronic Theses and Dissertations

This dissertation presents an innovative approach to examining the keying method, wording method, and construct validity on psychometric instruments. By employing a mixed methods explanatory sequential design, the effects of keying and wording in two psychometric assessments were examined and validated. Those two self-report psychometric assessments were the Effortful Control assessment (Ellis & Rothbart, 2001) and the Grit assessment (Duckworth & Quinn, 2009). Moreover, the quantitative phase utilized structural equation modeling to analyze 2,104 students’ responses and assess the construct of keying and wording. Various hypothetical models were investigated and evaluated. The reliability of each construct in each method was …

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 …

#Getinked: An Anthropological Exploration Of Tattooing And Social Media, Delanee Taylor

Electronic Theses and Dissertations

This thesis aims to address two inquiries regarding contemporary tattooing. The first goal is to explore how social media has changed the practice of tattooing while the second goal is to examine how tattoos are used to express or explore the differing facets of a person’s identity. Identity theory, social identity theory, semiotics, and the concepts of stigma and deviancy form the theoretical framework which allows one to understand the ways in which tattoos can provide insights into the various aspects of someone’s identity as well as how social media can influence members of the tattoo community. An online survey, …

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 …
