Silicon Dioxide Multimode Interferometer Spectrometers, James Harkness

Theses and Dissertations

Multi-mode interferometer (MMI) spectrometers are a type of reconstructive micro-spectrometer based on imaging light propagation patterns in MMI waveguides. This dissertation describes how the MMI spectrometer was implemented for the first time using a silicon dioxide core. This approach showed a 6 dB improvement in SNR over SU-8 core devices. To implement the silicon dioxide MMI spectrometer, a fabrication technique for selectively roughening the surface of the waveguide needed to be developed. SU-8, a photosensitive polymer, was etched with oxygen plasma to create grass-like nanostructures. SU-8 grass can then be used as a transfer mask to plasma etch a surface. …

Subversive Speculative Theology In Women's Stories From The Mormon Home Literature Movement, Rachel Meibos Helps

Theses and Dissertations

In the 1910s, Mormon women used sentimental speculative fiction published in official Relief Society Magazine to engage theological questions often reserved for male ecclesiastical authority. This paper examines three short stories: Edna Coray's "A Quitter–Almost." (1918), Lucy May Green's "A Whiff of Ether" (1919), and Laura Jenkins's "Beyond the Portals" (1916), each of which depicts a woman's encounter with the spirit world at the moment of death or near-death. Drawing on the Mormon Home Literature movement and the broader tradition of sentimental fiction as political and moral discourse, I argue that these authors used narrative to fill gaps in official …

An Examination Of K-12 Administrators' Philosophical Views On Music Education, Kathryn Ann Smith

Theses and Dissertations

K-12 administrators' beliefs about the purpose and value of music education have resulted in inconsistent support for students' access to music education in public schools. This study sought to examine administrators' philosophical views about music education and factors that may influence those beliefs, contributing the first known application of a praxial framework in assessing administrator belief systems. I developed a survey incorporating Song's (2025) Philosophical Beliefs Scale (Ph.B. Scale) to measure utilitarian, aesthetic, and praxial philosophical perspectives, along with key demographic and contextual characteristics. Participants (N = 65) were recruited via e-mail and K-12 administrator Facebook groups and represented a …

Ms-Gator: Multi-Scale Graph Attention With Topological Reasoning For Segmentation And Classification Of Prostate Cancer Based On Gleason Scores Using Histopathology Images, Sujata Patil, Mahadeva Swamy, Kavitha Sooda, Rajanikanth Vadigepalli, Khalid Nazim Abdul Sattar, Md Rafeeq

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Prostate cancer is one of the prevalent and potentially fatal malignancies, affecting men globally. Accurate segmentation and classification of prostate cancer in histopathology images remain challenging due to complex tissue architecture, staining variability, and high inter-observer differences in manual diagnosis. To address these challenges, this research proposes a Multi-Scale Graph Attention with Topological Reasoning (MS-GATOR) for segmentation and classification of prostate cancer based on Gleason Scores (GS). The MS-GATOR incorporates topological reasoning with hierarchical biological structures by constructing a graph-based representation among three spatial scales such as nuclei, glands, and tissues using Delaunay triangulation to capture both geometric and photometric …

Examination Of The Hiring Process: Bias In Selection, Conor Johanson

Honors Theses

Racial discrimination in the hiring process remains a persistent problem despite decades of anti-discrimination legislation and widespread bias-awareness training. The present study examined whether resume quality and candidate race jointly influence hiring evaluations among human resource professionals, a population with formal training in equitable selection practices. Using a 2 × 2 between-subjects design, 129 HR professionals recruited through Prolific were randomly assigned to evaluate a high- or low-quality resume attributed to either a Black or White candidate. Participant evaluations were assessed across warmth-related and competence-related dimensions derived from the Stereotype Content Model, with Aversive Racism Theory guiding predictions about when …

Bremsstrahlung Photons Emissions Measured At Different Rf Power In 28 Ghz Ecr Ion Source, Mwingereza John Kumwenda

Tanzania Journal of Engineering and Technology (TJET)

High-performance electron cyclotron resonance ion sources (ECRISs) generate large amounts of bremsstrahlung photons that affect the cryogenic systems due to the extra heat load that is produced. Thus, this study investigates the bremsstrahlung photons energy spectra at various RF powers, presenting some insight about the trends of the electron heating process inside the plasma. Bremsstrahlung photons from a 28 GHz ECRIS were measured at Busan center of Korean Basic Science Institute (KBSI). The gamma-ray detection system consists of three round-type NaI(Tl) scintillation detectors placed 620 mm radially from the beam axis at the extraction side of the ECRIS, and a …

Teaching To Discard Less Red On L & D Today For A Greener Tomorrow, Haley Primuth, Kari A. Schmidt Oliver, Katelyn Lackovich, Anne Getzin, Deborah Simpson

Aurora GME

Introduction

Climate change has known impacts on the health of the maternal-fetal dyad. Economic instability, flooding and displacement lead to reduced access to care, disrupted crop yields and food supply chains. Extreme heat has been linked to increased rates of fetal growth restriction, preterm delivery and stillbirth. Healthcare makes up 4.4% of net global emissions, and work on labor and delivery generates significant waste. Even when incineration of regulated medical waste (“red bag waste”) is done properly, there are still emissions which include greenhouse gases, heavy metals, toxins and particulate matter. It is estimated that 3-10% of total waste generated …

Critical Decisions Regarding Retirement, Philip Zettlemoyer

Senior Honors Theses

Many retirees in America do not understand the variables and important decisions that go into a retirement plan. These variables, however, have a significant effect on any retiree’s financial wellbeing. This case study explains such variables and decisions, as well as the various rules and regulations from the United States Government around the decisions. It then applies this knowledge of variables and regulations in a practical manner by analyzing a specific case study of a middle-class couple nearing retirement. This analysis includes in-depth projections for the couple’s specific situation which would traditionally be created with the expertise of a financial …

Glossip’S Road Map To Nowhere, Vida Johnson

Georgetown Law Faculty Publications and Other Works

The Supreme Court’s 2025 decision in Glossip v. Oklahoma was heralded as a victory for the defense. This essay argues that the 2025 Glossip decision does little to fix the myriad problems that led to Mr. Glossip’s wrongful conviction. While ultimately the Supreme Court reached the correct outcome this time, the ordinary judicial process and its purported safeguards were not what saved Mr. Glossip’s life. Rather, it was random chance that came to Mr. Glossip’s aid.

Ten years earlier, the Supreme Court, with many of the same Justices on the bench now, paved the way for Mr. Glossip’s execution. The …

Causes, Effects, And Solutions Of Wrongful Convictions, Allison B. Gobuzzi

Honors Theses

This study examines the wrongful conviction of Anthony Hinton and other examples that illustrate the causes of wrongful convictions in the United States and the effects that wrongful convictions have on the wrongfully accused and their families. This study uses research from scholarly articles and legal cases to analyze the factors that contribute to wrongful convictions and the impact on the wrongfully accused and their families. The research concludes that wrongful convictions are frequently the result of both evidentiary and procedural issues within the criminal justice system.

Health Awareness And Relative Energy Deficiency In Ultra-Endurance Female Athletes, Myshel Rodenbeck

Doctorate in Kinesiology

Ultra-endurance (UE) participation among female athletes has increased substantially, yet research examining health awareness and physiological risk in this population remains limited. Excessive training combined with inadequate energy intake places ultra-endurance female athletes at elevated risk for the Female Athlete Triad (FAT) and Relative Energy Deficiency in Sport (RED-S), both driven primarily by chronic low energy availability (LEA) and associated with menstrual dysfunction, impaired bone health, metabolic disturbances, and reduced performance.

This mixed-methods, cross-sectional study examined awareness of overall health, fueling behaviors, menstrual health, and recognition of FAT and RED-S among ultra-endurance female athletes over 25 years of age. Participants …

Advocacy, Outreach, And Expansion Of The Michigan Occupational Therapy Association Mental Health Special Interest Section, Isabel Evola

Capstone Projects

The history of occupational therapy (OT) is rooted in supporting mental health, emerging in the United States during World War I. Over time, the practice of OT has evolved in its scope and emerging specialties. The role of OT in mental health is underutilized and misunderstood by professional organizations. However, OT remains a vital service in supporting mental health in psychiatric and non-psychiatric settings. The focus of this doctoral capstone experience (DCE) was to address this gap by advocating for the presence and understanding of OT in mental health through the expansion of the Michigan Occupational Therapy Association (MiOTA) Mental …

Our Stories: Black Parents’ Experiences At K-12 Predominantly White Institutions, Jason Thompson

Dissertations

Black parents of Black children attending K–12 predominantly White institutions (PWIs) often experience stress as they navigate school environments where they may be perceived as uninterested, combative, or “token” members of the school community. These deficit-based perceptions can cause Black parents to limit school interactions, question whether their perspectives will be valued, and develop distrust toward school personnel. Although research has examined Black students’ experiences in PWIs, fewer qualitative studies have centered on Black parents’ stories. Capturing these experiences in parents’ own words helps challenge harmful stereotypes and offers schools, especially school counselors, deeper insight into strengthening relationships with Black …

The Spirit And The Letter: Performance Practice, Piano Pedagogy, And The Steinway Spirio, Rachel Chia, Jesse Puglia

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

Steinway’s Spirio high resolution player piano combines technology and musicmaking in ways that open new possibilities for piano pedagogy. But as of yet, these have not been extensively researched. The present study focuses on how classical piano students can emulate historical style and performance through the practice of embodiment as made possible by the Spirio. Steinway’s iPad app features historically significant video performances of “Steinway Immortals” which are synched to the piano as it replays performances by these musicians, bringing the past to life on the instrument the students are practicing on. To better understand character as expressed in performance, …

Challenging Implicit Racial Bias In Teacher Preparation: A Critical Race Theory Approach Using Counterstories, Delaney Ingbretson, Abigail Den Bleyker

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

This project examines the potential of counterstorytelling as a tool to disrupt implicit racial bias among pre-service teachers during the early stages of teacher preparation. Existing research consistently demonstrates that educators’ implicit attitudes influence expectations, disciplinary decisions, and interpretations of student behavior, often reinforcing racial inequities within educational systems. Because teachers play a critical role in shaping students’ academic achievement and social development, identifying strategies that address bias before educators enter the classroom is especially important.

Grounded in Critical Race Theory (CRT), this study investigates whether exposure to counterstories, narratives authored by people of color that challenge dominant racial ideologies. …

Correcting Faraday Cup Measurements Using Rutherford Backscattering, Spencer Hughes, A. Bunnell, J. Kim

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

Faraday cup is a conductive cup that measures the current of an incident beam of charged particles. Faraday cups are frequently used in particle accelerator-based studies where the beam intensity must be measured. A previous study determined the systematic error in Faraday cup measurements for a 3.4 MeV proton beam using Rutherford scattering at large angles. Our study builds upon this previous work to include six different beam energies ranging from 3.0 MeV to 0.6 MeV and two different incident masses (H and He). A silicon surface barrier detector measured the energy of back-scattered ions from a copper target. The …

Eigenmode Decomposition Analysis Of Resistive Magnetic Reconnection, Isaac Q. Evans

25th Annual A. Paul and Carol C. Schaap Celebration of Undergraduate Research and Creative Activity (2026)

Recent work demonstrates that specific aspects of nonlinear magnetic reconnection in a collisionless regime are directly attributable to linearly damped eigenmodes. In this work, we apply similar eigenmode analysis tools to characterize nonlinear magnetic reconnection driven by resistivity. In contrast to the collisionless case which contains a single unstable/stable eigenmode pair, the resistive case contains an unstable eigenmode and a wide spectrum of stable modes. Calculating eigenmode amplitudes allows for a determination of the significance of each eigenmode in the nonlinearly-evolved resistive reconnection. Linearly stable modes are found to be important in determining properties of nonlinear systems. We discuss how …

Toward A Horizonal "I": The Infinite Subject In William Wordsworth's The Prelude, Gabriella Lee Schwartz

Theses and Dissertations

In an 1805 letter to Sir George Beaumont describing his autobiographical poem The Prelude, William Wordsworth remarked that it was "a thing unprecedented in literary history that a man should talk so much about himself." Since then, critics have only affirmed Wordsworth's reputation as a poet, if not the poet, of selfhood and consciousness. Perhaps the most renowned scholarship on Wordsworthian subjectivity was produced by the so-called "Yale School" of the late twentieth century, as J. Hillis Miller, Harold Bloom, Geoffrey Hartman, and Paul de Man all published influential works on the topic. The latter two staked out stances on …

Observational data were aggregated from cohorts in six organizations in Canada, the USA, and Czechia. Prostate biopsies were performed between 2009 and 2024. Risk models (ClarityDX Prostate + DRE, ClarityDX Prostate + MRI, and ClarityDX Prostate + MRI + DRE) were derived (training cohorts n = 1626 to 2191) and validated (validation cohorts n = 378 to 1318) from …

A Computer Vision Approach To Analyzing Taxane Effects On Prostate Cancer Cells, Diana Elizabeth Dancea

Electronic Theses and Dissertations 2020 - Present

Actin is a family of proteins that help create the structure of the cytoskeleton, which gives shape to the cell. In many chemotherapy treatments, researchers target actin because it controls the cell division process. Therefore, if they are able to understand the actin fibers, that may help in formulating methods to stop or slow down cancer cells from reproducing. Another important protein is PAK6, which regulates actin. In our research, a collaborative effort with Prof. Michael Lu’s lab at Florida Atlantic University, we use machine learning techniques to analyze cells which had their PAK6 protein knocked out, and compare them …

Hypovolemic Shock In The Setting Of Third Spacing With Concentric Left Ventricular Hypertrophy: A Physiology-Guided Management Of Fluid Resuscitation—Case Report And Literature Review, Akram M. Eraky, Yasser Mokhtar, Guy Grabau, Adnan Khan, Mark Jarosz, Alisha Wright, Matthew Grounds, Kyle Kennedy

GME Publications

Patients with preload-dependent conditions are at high risk of hemodynamic instability from both hypovolemia and hypervolemia. In hypovolemic states, the presence of third spacing may be misleading and obscure true intravascular volume status. Therefore, management of critically ill patients should be guided by a thorough understanding of physiology and pathophysiology to appropriately address hemodynamic derangements. Overreliance on rigid protocols and protocol-driven care without adequate clinical judgment may, in some cases, adversely affect patient outcomes. Herein, we present a case of hypovolemia-induced hypotension in the setting of third spacing and concentric left ventricular hypertrophy.

Unseen, Unheard, Uninvited: Black Fathers And School Access In Redeveloped Spaces, James Dejong Alexander

Electronic Theses and Dissertations Archive

Abstract This qualitative study examined how three Black fathers in South Memphis's Foote Park/Foote Homes redevelopment area navigated school access for their children amid community displacement. Rooted in Community Cultural Wealth Theory (Yosso, 2005), which highlights the diverse forms of capital—aspirational, navigational, social, linguistic, familial, and resistant—that communities of color possess but are often overlooked by mainstream institutions, the research focused on three individuals: Mister Miles, Mister Otis, and Mister Langston. These pseudonyms honor Miles Davis, Otis Kaye, and Langston Hughes and position the fathers as holders of valuable community wealth whose educational navigation experiences constitute legitimate knowledge. Documentary sources …

Enhancing The Well-Being Of Refugees With Disabilities Through Equitable Access To Essential Services: A Participatory Qualitative Study In The United States, Mustafa Rfat

Brown School Graduate Student Theses and Dissertations

Access to services for refugees with disabilities (RwDs) is critically important for improving their well-being and enhancing their integration. This population often faces prolonged exclusion that begins in their country of origin and often continues to worsen during displacement, leading to accumulated disparities. Because the United States (U.S.) refugee program is structured around rapid employment, refugees who do not fit the fast-track employment criteria are often left behind. RwDs are often considered unemployable, which automatically shifts resources and services away from them. Abandoning RwDs during the critical period of resettlement puts them at heightened risk of increased and long-term exclusion. …
