Having Our Say: A Sociological Examination Of English Instruction In Urban High Schools And Effects On Black And Latino Identities, Jena Marie Escareno

Dissertations

This interdisciplinary study integrates a macro‑sociological perspective on language bias with an examination of English language instructional policies and practices that shape the identities of Black and Latino former urban high school students. Its purpose is to apply a sociological framework capable of illuminating the intersections of language, race, and social justice. By bridging linguistic, sociological, and educational theories, the study seeks to explain why current approaches to language instruction remain ineffective for urban learners and may inadvertently harm minority cultural identities.

Persistent disparities in urban academic achievement often highlight race and ethnicity as explanatory factors without acknowledging how these …

“The Thorns Of The Most Severe Virtue”: Education, Religion, And Cultural Power In Michigan, 1798–1855, Kyle Christopher Vanderwall

Dissertations

This project seeks to demonstrate the centrality of education and religion as cultural power levers used by Americans, Odawa, and Catholic missionaries. Though the power of each culture was uneven, efforts to create educational institutions imbued with different denominations of Christianity, as well as continued contestation over land, remade the cultures of all involved. Americans privileged state-building practices, the Odawa acculturated to remain in Michigan when removal policies were enacted throughout the United States, and the Catholic church attempted to proselytize Indigenous communities.

Although the ethnohistorical method needed to be understood in order to write this project, it is not …

I noted and …

Exploring The Lived Experiences Of Second-Career Educators, Kyle Avink

Dissertations

School districts across the United States face a persistent teacher shortage driven by high attrition rates, declining enrollment in teacher preparation programs, and increasing demands on educators (Carver-Thomas & Darling-Hammond, 2017). Teacher attrition is especially high within the first three to five years, with nearly 40-50% of new teachers exiting within their first five years (Carver-Thomas & Darling-Hammond, 2017; Cells et al., 2023; Gray et al., 2015; Ingersoll et al., 2025). In response, many states have expanded alternative certification pathways that allow professionals from other fields to enter teaching, making second-career educators a potential solution to workforce challenges (Afacan, 2022; …

The Impact Of Framing Effects And Moral Values On Prosocial Engagement, Olajuwon Olagbegi

Dissertations

Framing effects can shape perceptions, beliefs and behavior, particularly in prosocial contexts. The current study examined how language framing (social justice, social activism, volunteerism) and moral values influence interest in prosocial engagement across low- and high-cost helping scenarios. Participants (N = 219) were randomly assigned to one of three framing conditions and reported willingness to help in both low- and high-cost situations. They also completed the Moral Foundations Questionnaire. Replicating prior work (Olagbegi and colleagues, 2024), participants were more willing to engage in low- than high-cost helping. Across conditions, social justice framing elicited the greatest willingness to help. Higher fairness …

Lyapunov-Krasovskii Based Approach To Time-Delay Systems: Computational Efficiency And Feedback Control, Huan Phan

Dissertations

Time-delay systems arise naturally in many engineering applications due to sensing,actuation, communication, and computation delays. The presence of delays has a significant influence on system performance both positively and negatively. Although Lyapunov--Krasovskii functional (LKF) methods provide a systematic framework for stability analysis and controller synthesis, their implementation often suffers from high computational complexity, particularly for large-scale systems and systems involving multiple feedback channels. This dissertation addresses both computational efficiency and feedback control for linear time-delay systems.The first part of this dissertation develops a decomposition-based approach to reduce the computationalburden of stability analysis. By exploiting structured invariant subspaces associated with the …

Intelligent Surveillance For Weapon Threat Detection: Transformer-Based Detection And Segmentation Using Thermal And Rgb Imagery, Akhila Kambhatla

Dissertations

Proactive public-safety surveillance requires deep learning systems that can detect and segment weapons reliably under real-world conditions. This research develops and evaluates a progressive, multi-phase pipeline that moves (i) from RGB object detection to pixel-level semantic segmentation and (ii) from visible-spectrum cameras to thermal imagery to improve robustness under low-light, clutter, and occlusion. Early phases establish strong detection baselines using one-stage and two-stage detectors (YOLOv5 and Faster R-CNN) for multi-class weapon localization, followed by practical optimization through pruning and ensembling to reduce false positives and computational overhead while maintaining real-time feasibility. Building on the limitations of bounding-box localization, the methodology …

The Phylogenetic And Biogeographic History Of Cranes (Gruidae), Phillip Conrad Williams

Dissertations

Cranes (Gruidae) are a globally distributed clade of large, wetland-associated birds. Prior phylogenetic analyses have shown there to be two major subfamilies, Balearicinae and Gruinae, and five consistently recovered clades within Gruinae. However, the relationships among those five clades has remained contentious. In addition, little has been done to reconstruct the biogeographic history of cranes. To that end, I first inferred phylogeny using a large, nuclear dataset sampled from all 15 extant crane species and two outgroup species. The phylogeny mostly agreed with previous analysis using whole mitochondrial genomes but differed in that the Anthropoides species group formed a sister …

An Expertise-Based Approach To Training Decision-Making And Situational Awareness For Basketball Referees, Scott Warner Boatright

Enhancing Control Charting Schemes And Exploring New Assessment Metrics To Advance Quality Control And Cyber-Attack Detection In Manufacturing, Ahmad Al Majali

Dissertations

The increasing integration of digital technologies and industrial control systems in modern manufacturing has introduced new cybersecurity vulnerabilities within cyber–physical production environments. Malicious actors can exploit these vulnerabilities to induce subtle process deviations that degrade product quality while remaining undetected by conventional statistical monitoring tools. Such attacks can be deliberately engineered to manipulate process behavior through transient shifts that vary in magnitude, duration, and frequency. Despite extensive research on transient shifts caused by assignable causes in Statistical Process Control (SPC), limited attention has been given to intelligently designed cyber–physical attacks that exploit the structural characteristics and limitations of control charting …

Black Faces In White Spaces: Understanding School Belonging Among Black Adolescents At Nais Independent Schools, Letetsia Angelica Fox

Dissertations

Even though the National Association of Independent Schools (NAIS) has been committed to diversity for the last 30 years, they often focus their diversity efforts on all students of color instead of specific groups such as Black students (Brosnan, 2001). By not focusing on the specific experiences of Black students at independent schools, independent schools cannot truly foster a strong sense of school belonging for Black students because they do not understand the distinct barriers and factors that contribute to the development of school belonging for Black students who attend their schools (Hall & Stevenson, 2007).

This qualitative study sought …

A Phenomenological Study Of Teachers Who Use Oral Reading To Foster Student Reading Fluency And Engagement, Donyetta Grimes

Dissertations

The National Reading Panel (2000) recommends oral reading instruction as a means to improve overall reading fluency and reading comprehension. Oral reading fluency is a necessary foundational skill, and students who have not mastered it by the end of third grade, when students transition from learning to read to reading to learn, become struggling adolescent readers (Ming, 2018). Furthermore, there is a lack of research on reading fluency past the primary grades (Makebo et al., 2022). Additionally, research gaps exist when considering teachers’ actual practices during reading instruction (O’Sullivan et al., 2009). This gap is particularly concerning considering that teachers …
