From Deference To Dialogue: How International Gtas From High Power Distance Cultures Adapt To U.S. Classroom Dynamics, Deborah Akua Afi Appiah

Theses and Dissertations

International graduate teaching assistants (GTAs) from high power distance cultures play a significant role in undergraduate education at U.S. universities, yet they face challenges that go well beyond language proficiency. Coming from educational backgrounds where teacher authority is unquestioned and hierarchical, these GTAs must navigate American classrooms that operate on fundamentally different assumptions, where authority is earned rather than assumed, informality is the norm, and students expect to question, negotiate, and be personally known by their instructors. The present study examined how eighteen (18) international GTAs from seven (7) high power distance countries perceived and adapted to these differences while …

Thinking Machines: Cybernetics, Artificial Intelligence, And Technological Anxiety In The American Cold War, Erin Mae Wilcox

Theses and Dissertations

Following the Second World War, cybernetics emerged as a cross-disciplinary study in philosophy, neurophysiology, electrical engineering, and mathematics. Cyberneticists proposed the formal study of the man-machine analogy; that is, to equate biological structures to a complex mechanical system. Drawing from this analogy, cyberneticists used programmable digital computers to emulate the functions of the human brain. The study of artificial intelligence emerged within this cybernetic discourse in the early 1950s; yet, by the mid-1960s, the two disciplines suffered a methodological fracture. Drawing from a tradition generated by this fracture, historians have traditionally examined cybernetics and artificial intelligence in isolation from one …

Predicting Job Performance: The Incremental Validity Of Cognitive Reflection Tests Over General Cognitive Ability And Conscientiousness., Olivia Earll

Theses and Dissertations

Cognitive reflection is the ability to suppress intuitive thinking (Type 1) in favor of deliberative, analytical thought (Type 2). This study investigated cognitive reflection as a predictor of supervisor-rated job performance, exploring its incremental validity over general cognitive ability and conscientiousness. Results indicated that all three variables positively predicted job performance, with cognitive reflection explaining a significant, unique portion of the variance. Exploratory analyses confirmed that this predictive validity remained consistent across industry, age, and sex. Furthermore, cognitive reflection significantly moderated the relationship between general cognitive ability and job performance. These findings highlight the value of deliberative reasoning as a …

Data Defines Success: Algorithm For Dataset Quality Assessment In Deep Learning For Malware Detection, Matei Ionescu

Theses and Dissertations

The field of artificial intelligence is based upon the premise of constructing architectures through which to propagate training data. However, the majority of existing research literature is focused on architecture. While necessary, the attention devoted to the architecture should not so precipitously exceed that of the data. It should be noted that this disparity is not without reasonable cause. Data quality is often exceedingly difficult to verify due to particularities of the field or subfield; LLM repositories of text are distinct from image recognition pictures of dog breeds which are distinct from EEG waveforms of human brains which are distinct …

Fostering A Growth Mindset In Mathematics: Faculty And Student Experiences, Yolanda G. Rush

Theses and Dissertations

According to the Center for Community College Student Engagement (2019), many students attending two-year institutions need productive persistence strategies, including the development of a growth mindset. Although some growth mindset interventions have been effective in improving academic achievement among students (Boaler, 2016; Canning et al., 2024) and persistence (Lewis, 2019) among students, especially those with developmental needs (Suh et al., 2019) and those in mathematics, little is known about the experiences of students and teachers (i.e., students’ perceptions of teachers’ intentions and implementation) as teachers work to foster a growth mindset culture (Murphy et al., 2021). In this dissertation, I …

Rhetoric Of Realignment: An Analysis Of Trump's 2024 Campaign Rhetoric, David Valadez

Theses and Dissertations

When political coalitions include groups with opposing policy goals, leaders face a challenge: satisfying all constituencies without making commitments that alienate essential supporters. The present study examines strategic ambiguity in the form of deliberately vague political messaging as a tool for managing this challenge. Combining rhetorical analysis with selectorate theory, which explains how leaders achieve and maintain power through reward distribution, the research analyzes Donald Trump’s 2024 Republican National Convention acceptance speech, focusing on immigration rhetoric.

The analysis reveals that Trump’s ambiguity was selective rather than habitual. On immigration, where tech/corporate interests wanting skilled workers clashed with nationalist groups demanding …

Staff Attitudes Toward Ai Adoption At A Private Research University, Ashley C. Smith

Theses and Dissertations

This study addresses the limited research on university staff attitudes toward artificial intelligence use and adoption. Using the Unified Theory of Acceptance and Use of Technology (UTAUT) research framework, the General Attitudes towards Artificial Intelligence Scale (GAAIS), and quantitative survey methodology, the study examines the attitudes of higher education staff toward AI, specifically examining whether demographic or professional characteristics are factors. The findings indicate that staff had moderately negative attitudes toward AI while also expressing some concerns. The results suggest that more resources and support for AI are needed for staff to address concerns. It also suggests that construct-level analysis …

Constructing And Deconstructing Homelessness: Challenging The Stigmatization Of The Unhoused Through Lived Experience, Brenna Jones

Theses and Dissertations

As homelessness rises across the United States, public discourse plays an important role in shaping how the housing crisis is understood and addressed. This study examines how homelessness is constructed through local media narratives and how these constructions shape the experiences of unhoused individuals. Using a case study of Greater Bangor, Maine, this research combines a critical content analysis of 315 news articles from the Bangor Daily News (2020-2025) with in-depth interviews with 18 unhoused and precariously housed individuals. The findings demonstrate how media portrayals construct homelessness as a stigmatized identity associated with disorder, addiction, and danger. These narratives contribute …

Theses and Dissertations

In this dissertation study, I sought to identify the initial ideas that middle school students had when approaching Multiple Batches and Variable Parts proportion word problems, as well as the connections they made among those initial ideas. I conducted semi-structured individual and paired interviews with 13 sixth- and seventh-grade students at the end of their school year. I then used the Knowledge-in-Pieces theoretical perspective to identify knowledge resources that the participants accessed when approaching the tasks, prior to any intervention on my part.

Through my analysis, I identified 18 initial ideas that the middle school students employed when solving the …

Examination Of The Effects Aesthetic Enrichment And Music Have On Well-Being And Task Performance In A Workplace Simulation, Emily Budik

Theses and Dissertations

Workplace environments are often designed with a focus on efficiency, yet emerging research suggests that environmental features such as aesthetic enrichment and music may influence employee well-being and performance. The present study examined whether visual aesthetic enrichment and auditory stimulation through music could improve well-being, reduce stress, and enhance task performance within a simulated workplace task. Participants completed a 30-minute in-basket task under one of four conditions: a control environment, music only, aesthetic enrichment only, or a combined aesthetic enrichment and music condition. Measures of stress, well-being, and task performance were collected following task completion. Results indicated that neither aesthetic …

Data Utilization In Facilities’ Performance Management Decision- Making At U.S. Four-Year Public Institutions: A Cross-Sectional Exploratory Study, Tanaporn Supanichrattana

Theses and Dissertations

The growing complexity of higher education finance, aging infrastructure, and rising accountability expectations has intensified demands on facilities organizations to manage institutional assets strategically. As colleges and universities face sustained fiscal constraints and expanding operational pressures, the ability of facilities leaders to use data to inform performance management has become increasingly critical. Despite this importance, limited empirical research has examined how facilities leaders integrate data into decision-making within public higher education contexts.

The quantitative study employed a cross-sectional, exploratory survey design to investigate data utilization practices among facilities leaders at U.S. public four-year institutions. Guided by the Data–Information–Knowledge–Wisdom hierarchy and …

The Acculturation Of International-Born Student Affairs Administrators In The United States, Amber Joy Webb

Theses and Dissertations

This qualitative narrative study explored how international student affairs administrators in the United States experience acculturation. Guided by Berry’s (1997) fourfold model of acculturation, the study examined how participants experienced assimilation, integration, separation, and marginalization as they navigated their professional roles, institutional expectations, and cultural identities. Eight participants, representing diverse countries of origin, institutional types, and professional roles, were interviewed using a semi-structured interview guide. Data were analyzed using Braun and Clarke's (2006) framework. Findings indicated participants employed multiple, context-dependent acculturation strategies rather than adhering to a single strategy. Assimilation emerged as a strategic process for establishing professional legitimacy, navigating …

First- And Second-Generation Immigrant Emerging Adults’ Career Aspirations, Laura A. Botros

Theses and Dissertations

Despite first- and second-generation immigrants making up 19.6% of the U.S. workforce (U.S. Bureau of Labor Statistics, 2024), research exploring their career aspirations is scarce. Studies show that individuals’ cultural backgrounds significantly shape first- and second-generation immigrants' career aspirations, values, and professional goals (Kao, 2004; Polenova et al., 2017). The purpose of the study is to examine how first- and second-generation immigrant emerging adults' cultural backgrounds inform their career aspirations. I utilized a qualitative approach by asking participants about their cultural background, career aspirations, and what influenced their career aspirations. Interviews and a cognitive map activity were conducted to investigate …

"I Didn't Teach It Again Because It Wasn't Worth It": How Grades 6-12 English Language Arts Teachers Select Texts And Navigate The Obstacles That Impede Them, Steve Poggendorf

Theses and Dissertations

Classroom texts not only function as tools through which teachers can build curricula, but they can also engage and empower learners. Despite the importance of engaging texts in the classroom, teachers encounter obstacles, both social and institutional, that impede their ability to select the texts they believe will best foster student engagement and empowerment. The purpose of this qualitative study was to investigate how teachers make text selections, as well as the nature of the obstacles that stand in the way of teachers who hope to inspire and engage their students through lessons built around texts of their choosing. The …

Customers' Perceptions Of Customer Service After The Covid-19 Pandemic, Marissa Young

Theses and Dissertations

This thesis examines how customers perceive customer service after the COVID-19 pandemic, using qualitative data from an open-ended survey to evaluate how expectations, experiences, and the meaning of service have shifted. The findings demonstrate that consumers view customer service as a holistic process influenced by interpersonal communication, operational efficiency, product availability, and pricing transparency. Participants emphasized both positive and negative encounters, stating that the COVID pandemic fostered lowered expectations due to staffing shortages and work stress, while also remaining observant of service inconsistencies. These results relate to theories of service quality, emotional labor, and organization-public relationships by illustrating how crisis …
