Optimizing Hip And Knee Assistance For Walking And Sit-To-Stand Transitions: An Intrinsic Muscle Mechanics Based Predictive Approach, Neethan Ratnakumar

Dissertations

As the global population ages, the demand for wearable assistive technologies continues to rise, driven by their potential to enhance mobility and independence in older adults. Effectively designed controllers for lower-limb exoskeletons to assist sit-to-stand (STS) and walking are crucial for delivering efficient, safe, and comfortable assistance during daily activities. Traditionally, controller optimization involves biomechanical modeling and user-specific customization. Musculoskeletal simulations play a central role in this process by providing insights into human-exoskeleton interaction dynamics, thereby informing and refining control strategies.

This work presents a simulation-driven approach for developing exoskeleton controllers for walking and STS using two distinct methods: optimal …

Developing An Instrument To Measure Teacher Attitudes Toward Multilingual Pedagogies, Lauren H. Ramers

Dissertations

In an increasingly globalized world, substantial numbers of multilingual learners occupy K–12 and higher education spaces bringing diverse linguistic resources that, when intentionally and appropriately leveraged, can significantly enhance English language learning outcomes. Multilingual pedagogies, which honor and build upon students' full linguistic repertoires, are essential for fostering equitable and inclusive learning environments. This quantitative exploratory study investigated teachers' attitudes toward multilingual teaching with the goal of developing a reliable survey instrument—the Multilingual Pedagogy Scale (MPS)—to measure how teachers perceive language learning in multilingual classrooms and what they report doing in their classrooms.

First, a review of the research helped …

Racial Identity And Belonging Among Asian American Undergraduate Students In The Midwest, Seema M. Dahlheimer

Dissertations

Asian American students are often deemed overrepresented in higher education, leading to inequities in admissions, scholarships, and student support. This perception feeds and is fed by the model minority stereotype, which characterizes Asian Americans as hard-working and high-achieving and creates intense pressure to succeed academically (Poon et al., 2016). In addition, Asian American college students often experience racism and xenophobia, which can undermine their sense of belonging on campus. However, in the Midwest, where their immigration is more recent and conversations about race are often framed in terms of Black and white, Asian Americans often feel invisible and othered (Lee, …

Braingenebot: A Framework For Variant Prioritization And Generative Pretrained Transformer-Informed Interpretation Across Polygenic Risk Score Studies, Gang Qu, Nitesh Enduru, Xinyi Liu, Xiaoqian Jiang, Zhongming Zhao

Faculty, Staff and Student Publications

Polygenic risk scores (PRS) are widely used to assess genetic susceptibility in Alzheimer's disease (AD) research. However, the rapid expansion of PRS studies has led to dataset-specific biases-stemming from factors like population makeup, genotyping methods, and analysis pipelines-that result in inconsistent variant prioritization and limit generalizability and reproducibility. To address these challenges, we propose a transductive learning framework that integrates multiple PRS datasets for more robust risk variant prioritization, incorporating genome-wide association study (GWAS) priority scores as biologically informed priors. Additionally, we introduce BrainGeneBot, an AI-driven tool leveraging generative pretrained transformers with retrieval-augmented generation technology to streamline genomic analyses in …

Preparation, Development, And Refinement Of The Interview Protocol In Qualitative Research, David C. Coker, Adebowale Akande

The Qualitative Report

Interview protocols are by far the most common method utilized in qualitative research data collection. Novice and experienced researchers, from working on dissertations to grant proposals or other publications, often lack detailed interview design methods, as many educational programs do not require specific coursework on interview protocols and question development. To improve qualitative research, we make a proposal to incorporate an interdisciplinary approach that operationalizes three stages: preparation, development, and refinement. Preparation involves mapping the extant literature to define broad, narrow, and focused topics to write actionable standards, goals, and objectives. Development uses instructional design and educational psychology to construct …

Marnel Reina Mae Hernandez, MSN, RN

Joseph, F. Burkard, DNSc, CRNA, EBP-C

Background: Long-acting injectables (LAI) have been shown to be equally effective in viral load suppression. Implementing nurse led educational interventions in the use of oral treatment to LAI will address if LAI prescriptions can improve adherence and patient retention. Despite the availability of LAI for ART (antiretroviral treatment) and PrEP (pre-exposure prophylaxis for HIV) patients continue to have a low appointment adherence which can impact adherence and overall viral detectability. LAIs will continue to …

Compensation, Horizontal Diffusion, And Bottom-Up Pathways: State Climate Policies In The United States And Australia, Ian Bailey, Roger Karapin

Publications and Research

Recent years have seen growing interest in subnational governments as arenas of climate governance, but limited systematic research exists on the extent, conditions, or pathways through which subnational climate policies can influence, or compensate for deficits in, national policies. This article addresses this gap by examining options for states to influence climate policy in the United States and Australia, two countries where federal governments have made limited progress in developing national climate policies. As an analytical framework, it conceives a typology of state government approaches to climate policy that distinguishes among compensating, horizontal diffusion, and bottom-up pathways. It then uses …

No Trade Wars Without Taxation -Who's To Blame, And What Comes Next?, Domenico Imparato, Reuven S. Avi-Yonah, Doron Narotzki

Law & Economics Working Papers

As tariff policy once again shapes U.S. trade strategy, this article makes a foundational claim: trade wars are, at their core, tax wars. Against the backdrop of escalating economic tensions with the United States’ trade partners, this article argues that tariffs cannot be understood apart from the fiscal architecture that sustains them. What appears to be protectionism often masks deeper structural asymmetries in the U.S. tax system.

The discussion proceeds through three interrelated dimensions: reshoring production, promoting fair trade, and raising revenue. In each, the interaction between tariffs and the tax system reveals deeper distortions. U.S. export mechanisms such as …

We analyse a selection hyper-heuristic (SHH) and NSGAII for the multi-objective cardinality constrained portfolio optimisation problem, an NP-hard problem addressing the asset allocation trade-off between return and risk under constraints of the number of assets. We evaluated the performance of the SHH and NSGA-II for cardinality constraints K = {2, 5}. Our results are competitive with those of NSGA-II.

Utilizing Simulation Training To Understand Maternal Cardiac Arrest Precipitated By Amniotic Fluid Embolism: A Quality Improvement Project, Erica L. Wright, Megan L. Tiernan, Michael W. Neft, Paige Spagiare, Erica Coffin

Doctor of Nurse Anesthesia Practice (DNAP) Manuscripts

Background and Problem: Maternal cardiac arrest precipitated by amniotic fluid embolism is among the leading direct causes of death among laboring women (Enomoto et al., 2022). Because it presents suddenly without any immediate apparent cause and lacks specific diagnostic tests, frontline obstetric caregivers must be vigilant, competent, and prepared to handle this potentially catastrophic emergency. Coordination among multiple disciplines is paramount since two lives, not just one, are at risk. Unfortunately, the rarity of maternal cardiac arrest significantly limits opportunities for staff to learn how to identify and manage these events successfully. Method: This quality improvement project established a simulation-based …

Charles Coughlin: Conspiratorial Radicalization And The Making Of A Fascist, Rachel D. Thompson

Graduate Masters Theses

This paper traces the radicalization of Father Charles Coughlin, a radio populist radio preacher from the 1930s who is most well known today for the extreme anti-Semitism and fascist tendencies which defined the later parts of his career. It seeks to determine why Father Coughlin became a fascist, as well as examining how much of his fascism was evident in his earlier years. Major areas of focus include: 1) A conspiratorial anti-Communist worldview that would align Coughlin with right-wing authoritarianism and was present from his early days. 2) His ascent to becoming a national figure as a populist radio preacher …

Low-Cost Cutaneous Protoporphyrin Ix (Ppix) Detection (Cpd) Device For Follow-Up Monitoring Of Patients After Photodynamic Therapy, Md Asaduzzaman Rasel

Graduate Masters Theses

Background: Photodynamic Therapy (PDT) utilizes specific wavelengths of light to activate photosensitizing chemical compounds, known as photosensitizers, which induce the generation of cytotoxic reactive oxygen species (ROS) for the targeted destruction of cancer cells. Among various photosensitizers for PDT, Protoporphyrin IX (PpIX) is widely employed in oncology and dermatology due to its natural in situ generation via the metabolic conversion of 5- aminolevulinic acid (ALA), a non-phototoxic prodrug. Systemic administration of ALA after 3-6 hr drug delay leads to peak PpIX accumulation in tissues, facilitating therapeutic and diagnostic applications. However, PpIX can persist in the skin for 24–48 hours post-treatment, …

Ultimately, their efforts were critical to the expansion and global recognition of Leominster’s plastics industry. Yet the role of immigrant …

Sugar: A Sequence Unfolding Based Transformer Model For Group Activity Recognition, Yash U. Gondkar

Graduate Masters Theses

Large Language Models have improved significantly in the past couple of years due to the adoption of transformers. However, transformers still find it challenging to process videos due to limited context size caused by their quadratic computing cost. Therefore, we studied a booming field in machine learning which powers applications like social scene analysis and video surveillance systems called Group Activity Recognition (GAR). We found that recent models were able to achieve more than 90% accuracy on popular datasets like the Volleyball dataset, however, it turned out that even they relied on transformers.

Therefore, in this work, we developed a …

On Being The Only: Using Black Feminist Thought And Hermeneutic Phenomenology To Deeply Understand Onliness As Experienced By Black Women In Stem, Karen M. Jarvis-Thorne, Karen M. Jarvis-Thorne

Graduate Doctoral Dissertations

When a Black woman persists in a STEM undergraduate academic space as the only Black woman in that space, how is she shaped as a human being? How does she fare? How does the experience influence her decision making as she contemplates graduate school applications? Does the experience guide her decision to stay or leave STEM? In this study, the author used Black Feminist Thought to provide cultural and critical oversight of her engagement with Hermeneutic Phenomenology. Hermeneutic Phenomenology requires this oversight because the methodology’s theoretical foundations are grounded in Heidegger’s Nazism and should be critiqued if and when appropriate …

The Gendered Role Of Friendships For Advanced Care Planning And Health In Later Life, Zee Kee Emily Lim

Graduate Doctoral Dissertations

Friendship is becoming more pertinent to older adults because they are increasingly living with fewer family ties in later life due to changing social and demographic trends (Fiori et al., 2020; Verdery et al., 2019). However, friendships are not as extensively studied as compared to family relationships (Blieszner et al., 2019). Thus, additional research is needed to better understand the influence of friendships on health and health behaviors in later life.

This dissertation includes three studies that focus on the association between friendship and loneliness, advanced care planning, and cognitive function, examining the role of gender in these three studies, …

Pipeline Vs. Choice: The Global Gender Gap In Stem Applications, Isaac Ahimbisibwe, Adam Altjmed, Georgy Artemov, Andres Barrios-Fernandez, Aspasia Bizopoulou, Martti Kaila, Jin-Tan Liu, Rigissa Megalokonomou, José Montalban, Christopher Neilson, Jintao Sun, Sebastian Otero, Xiaoyang Ye

Cowles Foundation Discussion Papers

Women account for only 35% of global STEM graduates, a share unchanged for a decade. We use administrative microdata from centralized university admissions in ten systems to deliver the first crossnational decomposition of the STEM gender gap into a pipeline gap (academic preparedness) and a choice gap (first-choice field conditional on eligibility). In deferred-acceptance platforms where eligibility is score-based, we isolate preferences from access. The pipeline gap varies widely, from -19 to +31 percentage points across education systems. By contrast, the choice gap is remarkably stable: high-scoring women are 25 percentage points less likely than men to rank STEM first.

Design And Development Of A Standalone Digital Holographic Microscope Employing Phase-Driven Reconstruction And Classification For Biomedical Imaging And Optical Diagnostics, Charlotte Kyeremah

Graduate Doctoral Dissertations

Access to advanced biomedical imaging technologies remains a significant challenge in resource-limited settings, especially for early disease detection and monitoring of diseases such as malaria, HIV, and other blood-borne diseases. Although point-of-care (POC) devices have gained popularity in global health, many rely on antibody-based tests, lateral flow strips, or optical readouts that often lack quantitative capabilities, sensitivity to early infections, or versatility in different diagnostic targets. In addition, these systems are typically dependent on disposable reagents or manual interpretation, which limits their effectiveness in remote areas. Digital Holographic Microscopy (DHM) presents a promising alternative as a label-free imaging method capable …

Subsidiarity In The Shadow Of Sovereignty, Loren King

Political Science Faculty Publications

Subsidiarity frustrates. It admits of clear articulation as an ideal (‘vest authority as close as feasible to those most affected’) but then invites conflicting interpretations and elaborations. As a workable principle, subsidiarity seems to founder exactly when we need it: when we ask what, precisely, that principle regulates. As a regulative moral precept, subsidiarity promises a politics sensitive to diverse needs and responsive to local knowledge, yet in practice any implementation of the ideal pulls us back toward an authoritative center to regulate disputes and coordinate all of this local wisdom. I love subsidiarity for these frustrations and ambiguities. In …

Infrastructure Equality, Deborah N. Archer, Yuvraj Joshi

Northwestern University Law Review

The United States’ racialized geographies have left communities of color with systematically inferior essential infrastructure that perpetuates their social and economic exclusion. From roads, public transportation, and sewage systems, to banks, high-speed internet, and high-quality public schools, people and communities of color have limited access to the fundamental infrastructure necessary to lead socially and economically vibrant lives. This Essay introduces “infrastructure equality” as a unifying framework to address the critical intersection of physical, social, and legal infrastructures that feed racial inequality. Drawing on multidisciplinary research, it argues that infrastructure—the interconnected and vital system of physical structures, networks, and social institutions—should …

Expression Graph Network Framework For Biomarker Discovery, Yang Liu, Jason Huse, Kasthuri Kannan

Faculty, Staff and Student Publications

Biomarker discovery for complex diseases, such as cancer, hinges on uncovering molecular signatures that capture intricate, interconnected relationships within biological data-a challenge that traditional statistical and machine learning methods often fail to meet due to the complexity of high-dimensional gene expression profiles. To overcome this, we introduce the expression graph network framework (EGNF).
