Simulation And Experiment Of Two-Bunch Wakefield Dynamics And Energy Recovery In Dielectric-Lined Thz Structures, Calcifer Phillips

Graduate Research Theses & Dissertations

Beam-driven structure wakefield acceleration (SWFA) is a proposed method of particle acceleration that produces higher acceleration gradients. This technique could lead to the development of smaller and more efficient particle accelerators. In SWFA, a charged "drive" bunch passing through a dielectric or metallic structure created an electromagnetic "wake" field which can then be used to accelerate a following "witness" bunch. This work studies the effects of structure geometry on wake excitation, presents simulation results of wakefield dynamics in various geometries, and explores how SWFA could be used to achieve higher energy gradients. The use of a circular cross-section structure was …

Nutritional Niche Separation Amongst Sympatric Threatened Lemurs: The Role Of Micronutrients In Food Selection And Implications For Physiological Health, Maire K. O'Malley

Graduate Research Theses & Dissertations

Madagascar’s biodiversity is heavily affected by anthropogenic change and consequently, conservation management plans need to reflect current research to protect biodiversity. Primate nutritional ecology offers valuable insights into ecology, evolution, health, habitat requirements, social behavior, and conservation management strategies. Macronutrients (fat, carbohydrates, and protein) provide consumers with energy whereas micronutrients (vitamins and minerals) are essential to metabolic processes but are frequently overlooked. This study provides a novel examination of dietary niche separation by comparing mineral consumption between three sympatric species differing in feeding strategies: 1) Grey Bamboo lemur (Hapalemur griseus), a bamboo specialist, 2) Diadema sifaka (Propithecus diadema), a folivore, …

High-Throughput Strip Clustering On Fpgas For The Hl-Lhc, Hayden Shaddix

Graduate Research Theses & Dissertations

With the advent of the High-Luminosity Large Hadron Collider (HL-LHC), the demand for modern approaches to high-throughput data processing has increased substantially. The HL-LHC will deliver far higher collision rates (pile-up reaching ⟨μ⟩ ∼200), producing a dramatic rise in detector activity and placing significant pressure on real-time reconstruction algorithms. One strategy for meeting this challenge is to leverage commodity hardware such as field-programmable gate arrays (FPGAs) and graphics processing units (GPUs), which can accelerate bandwidth-intensive portions of the reconstruction chain. In particular, FPGAs programmed through high-level synthesis (HLS) offer a promising balance between flexibility and performance, allowing physicists to design …

K–12 Teacher Intention To Use A Makerspace: An Analysis Using The Unified Theory Of Acceptance And Use Of Technology, Kevin W. Rutter

Graduate Research Theses & Dissertations

This study examines the factors that relate to K–12 teachers' intention to use a makerspace for classroom instruction. It uses the unified theory of acceptance and use of technology (UTAUT) as its theoretical framework. The research addresses gaps in the United States' achievement in STEM subjects and explores makerspaces as a potential instructional innovation that encourages student-centered, interdisciplinary, project-based learning. A quantitative, correlational case study design was employed to survey 120 staff members at a large urban high school in the Midwest with a dedicated makerspace. Survey items were adapted from the UTAUT model to assess three predictor variables: performance …

Can A "Good Jab" Lead To A "Good Job?": Teasing As An Organizational Performance Feedback Tool, Jared P. Wilson

Graduate Research Theses & Dissertations

Performance feedback is a valuable tool for bolstering workplace performance, but the prospect of receiving feedback is often aversive, leading to decreased acceptance, increased turnover intent, and increased recipient stress. One plausible explanation for why critical feedback can be aversive is that feedback is face-threatening. Politeness theory suggests that pro social agents can intentionally attenuate face-threat while still communicating intrinsically threatening information. Pro-social teasing, a humorous form of off-record communication, is one such method, offering a potentially less aversive mode of performance feedback. A sample of 133 participants read a vignette where they took on the role of a grocery …

Instruction Vs. Infrastructure: Asymmetric Returns In U.S. Higher Education, Shaibu Yahaya

Graduate Research Theses & Dissertations

Despite massive increases in funding, U.S. higher education degree output has stagnated—a paradox often attributed to external cost pressures like Baumol’s cost disease. This paper tests an alternative hypothesis: that internal resource misallocation, specifically the accumulation of noninstructional liabilities, actively crowds out educational productivity. Using a panel of 26,603 institution-year observations, I estimate the university production function via a fixed-effects Poisson specification, adjusting all financial inputs using the Higher Education Price Index. The results expose a stark asymmetry in productive returns: a 10% increase in instructional spending drives a 1.76% increase in degree production (β = 0.176). In contrast, the …

The Final Boys' Club: Conceptualizing A Final Boy Of 1980s Horror, Ej Newton

Masters Theses

Carol J Clover’s (2015) Final Girl, the female slasher protagonist who survives to the end of the movie, has become a staple of horror scholarship, providing insight into the function of gender within the genre as well as our cultural beliefs surrounding femininity. Given the attention paid to horror’s leading ladies, however, another fascinating figure has gone unexplored: the Final Boy. This project analyzes nine horror films from the 1980s with young male protagonists in order to conceptualize and critique this previously unidentified trope. Utilizing McKerrow’s (1989) critical rhetoric as a guide, this research not only provides a thorough definition …

It Takes A Village: Residents’ Perceptions Of Mount Prospect’S Place Branding, Jenna Strauss

Masters Theses

The Village of Mount Prospect has heard a fair share of negative critiques about the village’s branding; however, officials have not yet taken the initiative to rebrand. As stated by a village official, the village needs to understand what residents think about the branding before considering a rebrand. This knowledge offers valuable insight into what branding elements are liked/valued by residents, but also whether a rebrand would cause resistance or a mini crisis. Place branding literature highlights that residents determine the authenticity of a place brand (Braun et al., 2013), so Mount Prospect officials seek to make future branding decisions …

“To Hell With Words, [Say] Something!”: An Expressivist Manifesto For The Revival Of Authentic Voice Amid Robocolonial Echoes Of Llms In Composition Studies, Dani Rose Fitch

Masters Theses

This article explores the intersection of composition pedagogy and generative artificial intelligence (GenAI), arguing that large language models (LLMs) impose a robocolonial standardization of language. By mass-producing algorithmically predictable text based on Standard American English (SAE), LLMs threaten the tenets of Students’ Right to Their Own Language (SRTOL) and drown out diverse linguistic identities. The author distinguishes between the embodied, intentional discovery of meaning in human intelligence and the voiceless echo of formulaic LLM generation.

Applying Baudrillard’s theory of simulation, the author positions GenAI-produced texts as pure simulacra—copies that have lost all connection to a human referent. By synthesizing Baudrillard’s …

Shadow Of The Rising Sun: How Japanese Culture Was Transferred To The United States Via Foreign Policy, Alex Pearson

Masters Theses

Post-World War II U.S. economic foreign policy towards Japan aimed to revitalize the war-torn country’s economy and spread democracy to the East. The economic foreign policy enacted by the United States to revitalize the Japanese economy resulted in an increase and “normalization” of Japanese culture in America. This thesis explores the connection of post-war American foreign policy to the increase of American exposure to Japanese culture that sparked normalization. By focusing on the efforts of U.S. policymakers and the positive media coverage of Japanese culture in the United States, a clear correlation between economic foreign policy and the normalization of …

Most administrators (74%) found the FCOT to be an acceptable …

Hierarchical Analysis Of Predictors Of Public Speaking Anxiety, Ruimin Peng

Masters Theses

Public speaking anxiety (PSA) is a prevalent type of phobia that shares many similarities with social anxiety. This paper examines factors related to social anxiety and PSA. Previous literature has identified self-efficacy, perfectionism, and fear of negative evaluation (FNE) as factors related to both social anxiety and PSA. However, less attention has been given to fear of positive evaluation (FPE) and international status, although these two factors are likely related to PSA. This study employed hierarchical regression analysis to investigate the predictive power of FPE and international status on PSA, while controlling for self-efficacy, perfectionism, and FNE. FPE, academic status, …

Lucretius, Ovid, And Milton In Seventeenth-Century England: First Matter, Creation, And Food Of Angels, Conny M. Pfeifer

Graduate Research Theses & Dissertations

Paradise Lost is a complex poem that not only contains John Milton’s rendition of the Genesis creation narrative and the Fall of humankind but also provides a voice for his unique theology. This dissertation argues that Milton’s creative use of the three disparate concepts of consuming and digesting knowledge, chaos, and the night sky allows him to respond to Lucretian atomism, to address questions regarding the mortality of the soul, and to navigate the scientific discoveries of the seventeenth century, especially the astronomical discoveries of Galileo Galilei. An examination of digestion, chaos, and night helps shed light on Milton’s unique …

Rebooting Administrative Enforcement For The Information Economy, Nina-Simone Edwards

Library Scholarship

This concept paper considers how to strengthen the enforcement of public mandates to deter harmful practices and business models. The paper offers principles for reinvigorated enforcement such as enhanced visibility, the increased use of design as a remedial lever, and personal responsibility for responsible individuals, not only the corporations that employ them.

To advance these principles, we call for new or amended laws that require companies to document how policy becomes code, grant agencies authority to order design changes to products and services, create pathways for charging responsible individuals, and cabin some forms of prosecutorial discretion. We would support these …

Legitimacy And Accountability In The Information-Era Administrative State, Nina-Simone Edwards

Library Scholarship

The current assault on administrative institutions and the rapid influx of automated “solutions” have exacerbated the problems of a system that was already buckling under the strains of functional opacity, technical opacity, unequal access and influence, process proliferation and paralysis, and inaction. An overarching reason for the legitimacy and accountability challenges confronting the administrative state is a paradigm for administrative legitimacy and accountability that is court-centered and no longer fit for purpose.

In this concept paper, we describe two core requirements of legitimacy and accountability–which, as we will explain, are interdependent concepts–and then articulate three component requirements–transparency and demystification, care …

Exploring The Academic Trajectories Of Transfer Students Enrolled In An Introduction To Proof Course And Their Self-Efficacy For Proving, Sundas Hussain

Mathematics Dissertations

Transfer students entering proof-based mathematics courses face a double transition: they are adjusting to a new institution while simultaneously learning to construct mathematical proofs. Although transfer students have been widely studied in higher education and self-efficacy for proving has received increasing attention in mathematics education, little research has examined the intersection of these two areas. The purpose of this study was to better understand how transfer students’ academic trajectories shape their self-efficacy for proving. This multiple case study examined twelve transfer students enrolled in an Introduction to Proofs (ITP) course, using Bandura's (1997) four sources of self-efficacy as the …

Targeting Nuclear Receptors In Muscular Dystrophies And Regenerative Myogenesis, Eira Mann, Hoang Vu, Vihang A Narkar, Yu Liu

The Brown Foundation: Institute of Molecular Medicine

Skeletal muscle is a highly plastic tissue with a robust capacity for regeneration, largely driven by resident satellite cells. Muscular dystrophies comprise a heterogeneous group of inherited disorders characterized by progressive muscle degeneration, chronic inflammation, and impaired regenerative capacity. Despite well-defined genetic etiologies, effective disease-modifying therapies for these disorders, as well as many acquired myopathies, remain limited. Emerging evidence identifies nuclear receptors (NRs) as key regulators of skeletal muscle homeostasis, integrating hormonal, metabolic, and environmental signals to control transcriptional programs governing mitochondrial function, metabolism, inflammation, and myogenesis. In this review, we summarize the diverse roles and mechanisms of action of …

Immune Checkpoint Inhibitor-Induced Cardiotoxicity: From Immune Mechanisms To Clinical Surveillance And Targeted Therapies, Nathan K Chen, Kathryn D Hok, Narsi Chokshi, Anthony Shadid, Haydn E Rich, Lavanya Gunamalai, Marie-Francoise Doursout, Nirmal K Banda, Pooja Shivshankar

The Brown Foundation: Institute of Molecular Medicine

Immune checkpoint inhibitors (ICIs) have transformed the treatment landscape across a broad range of malignancies by restoring antitumor immunity through blockade of key inhibitory immune pathways, including programmed death receptor-1 (PD-1), programmed death ligand-1 (PD-L1), and cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4). Yet the same widespread immune activation that drives their therapeutic benefit renders patients susceptible to immune-related adverse events (irAEs). Among these cardiovascular toxicities have emerged as a particularly critical concern, drawing growing attention within the evolving field of cardio-oncology. ICI-associated cardiotoxicity encompasses a broad clinical spectrum, ranging from myocarditis and pericarditis to arrhythmias, heart failure, and vascular complications. Of these, …

The assessment found that place-based learning on global issues enhanced students' understanding of the meaning of global citizenship in a globalized world. Based on a qualitative evaluation of their key assignments, students successfully articulated threads and connections between local community concerns and issues as globally situated communicative phenomena. …

Learning About Land Through Indigenous Storywork, Critical Information Literacy, And Archival Research At The Northern Shores Storywork Project Site, Kel Sassi

Journal Articles

This article takes a critical approach to an Information Literacy and Leadership Institute (Institute) for Upper Peninsula K-12 educators with the goal of coming to terms with the dispossession of Indigenous peoples in the region. Participants learned about critical information literacy in relation to archival materials about settler colonization and resource extraction and created curriculum materials for their classrooms. Facilitators designed institute activities with Archibald’s Indigenous Storywork principles in mind and analyzed the outcomes through this framework. The focus on land was reflected in teacher materials, but could be integrated more deeply in future institutes.
