Subjection To Chivalry: Agency, Consent, And Assault In Roman De Silence And Sir Gawain And The Green Knight, Jeremy Clay Birchfield

ETDs from 2020-2029

Violations of consent and sexual assault occurred frequently within the genre of romance popular across medieval England and France during the late Middle Ages. While many of the characters who experienced sexual assault in these pieces of literature were women, “Subjection to Chivalry” investigates two masculine characters whose consent is violated within their respective romances. The essay explores how the experiences of Silence, the Roman de Silence’s protagonist, and Sir Gawain of Sir Gawain and the Green Knight can read as violations of consent and assault at the hands of both male and female aggressors, and questions how those violations …

Histone Deacetylases In Kidney Injury: Distribution, Injury-Specific Regulation, And Fibroblast Hdac1 Function, Huy Nguyen

ETDs from 2020-2029

Acute kidney injury (AKI) is increasingly recognized as a major contributor to the development of chronic kidney disease (CKD) through maladaptive repair and interstitial fibrosis. Epigenetic regulation has emerged as a critical factor of kidney injury responses, however the injury-specific and cell-type specific roles of histone deacetylases (HDACs) remain poorly defined. This dissertation investigates the regulation and functional significance of HDACs in kidney injury, with a particular focus on fibroblast HDAC1 as a mediator of interstitial fibrosis development following AKI. In my cisplatin-induced AKI model, a single dose of cisplatin caused a significant decline in kidney function in both male …

Toothbrush Resistance Of Resin-Based Stain And Glaze Materials Applied To 3d-Printed Denture Resins, Panisa Homyai

ETDs from 2020-2029

Background: Three-dimensionally printed (3D-printed) dentures are commonly fabricated using a single tooth-colored resin, after which surface stain and glaze coatings are applied to reproduce gingival coloration, enhance the esthetic appearance and improve clinical longevity of characterized prostheses. However, daily oral hygiene procedures such as toothbrushing degrade surface coatings, leading to discoloration, increased plaque retention, and deterioration of esthetic appearance. Objectives: To evaluate the effect of stain timing and glaze application on the surface gloss and roughness of a three-dimensionally printed denture resin before and after simulated toothbrushing Methods: 80 disc-shaped specimens (12 mm in diameter and 3 mm in thickness) …

Mindfulness Across Media: Examining The Effects Of Audio, Audio-Visual, And Virtual Reality Mindfulness Interventions On Social Media Mindsets And Psychological Wellbeing, Rashmi Salian

ETDs from 2020-2029

Social media is so deeply ingrained and integrated into daily life that concerns about its impact on psychological wellbeing continue to grow, prompting pressing questions about how to foster healthier and more intentional use of technology. Recent studies suggest that low-agency mindsets toward social media lead users to develop habitual usage patterns and ambiguous information consumption behaviors, both of which negatively impact psychological outcomes. However, limited research is available on mechanisms that could effectively alter these mindsets. This study uses an experimental methodology to investigate whether mindfulness interventions delivered through varying levels of media immersion can improve psychological mindsets toward …

Bringing Clarity To Tutors' Work: Designing An Effective Writing Center Staff Handbook, Maria Bunting

ETDs from 2020-2029

Writing center literature often focuses on the documents used to justify a center’s role in the larger institution while largely ignoring internal documents that aid in training. By also answering Babcock & Thonus (2012) and Driscoll & Perdue (2014)’s call for more replicable, aggregable, and data-based (RAD) research in writing centers, this study addresses this literature gap by conducting a qualitative study about a newly-implemented handbook at a public R1 university. The author first includes a description of the collaborative document creation process before describing the empirical methods used to assess the handbook’s effectiveness. The findings illustrate how effective handbooks …

Mechanisms Of Cyst Initiation And Expansion In Polycystic Kidney Disease: Alterations In Tubule Flow Dynamics And P21- Driven Epithelial Reprogramming, Isis Thomas

ETDs from 2020-2029

Autosomal dominant polycystic kidney disease (ADPKD) is a common inherited disorder characterized by progressive cyst formation, kidney enlargement, and eventual renal failure. Mutations in PKD1 or PKD2 disrupt polycystin-mediated mechanosensory signaling in renal epithelial cells, altering calcium signaling, epithelial architecture, and cellular homeostasis. Although cyst expansion has historically been attributed to epithelial hyperproliferation or tubule pinching off to form a cyst that no longer remains connected with the tubule, the early physiological and molecular events that initiate cyst formation remain incompletely understood. This dissertation investigates how alterations in tubule flow dynamics and epithelial stress responses contribute to cyst initiation and …

Investigation Of Air Emissions With A Local Composites Industry, Chris White

ETDs from 2020-2029

Workers at an office space raised complaints about a sweet-smelling odor directly outside their building. After an initial assessment of the surrounding businesses and their processes, it was determined that the workers were most likely exposed to styrene emissions from a nearby composites company. This investigation utilizes multiple weeks of direct readings with a photoionization device and active environmental sampling with a charcoal tube and pump to confirm the styrene exposure hypothesis. Weather trends were also recorded to determine correlation between weather and exposure to the sweet-smelling chemical. The direct readings found an exposure maximum of less than 2 ppm …

Holding The Dying: Worldview, Community, And The Practice Of End-Of-Life Doula Care, Amy J. Shields

ETDs from 2020-2029

As populations age and chronic illness increasingly characterizes the final stages of life in the United States, end-of-life doulas (EOLDs) have emerged as non-medical practitioners who support dying people and their families through education, companionship, advocacy, and ritualized care. Drawing on a thematic analysis of 18 semi-structured interviews with practicing EOLDs across the United States, this thesis examines how EOLDs conceptualize a “good death,” navigate emotionally intensive work, and sustain themselves in an unregulated and often marginal professional landscape. Situating EOLD practice within anthropological scholarship on death and dying, the study highlights the ways EOLDs challenge dominant biomedical narratives that …

Enhancing Dynamic Balance And Mobility In Adolescents With Cerebral Palsy Or Spina Bifida, Phuong Thi Minh Quach

ETDs from 2020-2029

Cerebral Palsy (CP) and Spina Bifida (SB) are among the most prevalent pediatric neuromotor impairments, posing significant challenges to independent mobility and dynamic balance. Although arising from different neurological origins, CP from non-progressive brain disruptions during development and SB from lower motor neuron lesions in the neural tube, both the conditions often lead to similar functional limitations, including muscle weakness, impaired gait and limited mobility. Affected children typically exhibit compromised postural control and an increased dependence on assistive devices. Over time, this decline in independent physical activity often triggers secondary health issues, such as early onset of osteoporosis, hypertension, and …

The Role Of 14-3-3 Proteins In The Pro-Inflammatory Response Of Microglia And The Neuronal Stress Response To Trichloroethylene Exposure, William Stone

ETDs from 2020-2029

ABSTRACT This dissertation examines how 14-3-3 proteins, with a focus on the 14-3-3θ iso-form, regulate signaling pathways relevant to neurodegeneration. While tradition-ally described as molecular hubs that organize protein–protein interactions, our work reveals how 14-3-3 function is shaped by environmental insults, namely bac-terial and neurotoxicant exposures, and how its disruption contributes to disease-associated processes. Two complementary approaches were used, focusing on microglial inflammatory signaling and neuronal responses to an environmental neurotoxicant, to define a broader role for 14-3-3 proteins in disease associated pathways in the brain. Chapter I identifies 14-3-3 proteins as modulators of microglial activation. Disrup-tion of 14-3-3 interactions …

Nitrite Oxidation During Ozonation Revisited: Mechanisms Of Nitration Reactions, Tarek Manasfi, Christoph Dieziger, Simon A. Rath, Daisuke Minakata, Urs Von Gunten

Michigan Tech Publications

The formation of toxicologically relevant nitro compounds has been observed during ozonation of nitrite-containing secondary wastewater effluents, but their formation mechanism remains unknown. To identify key nitrating species, three reaction systems were investigated: ozonation of nitrite (O3/NO2^–), peroxynitrite (ONOOH/ONOO^–), and hydroxyl radical oxidation of nitrite with γ-radiolysis (γ/NO2^–). Nitrite ozonation (O3/NO2^–) yielded significant amounts of the nitrating agent nitrogen dioxide ^•NO2 (9.4% at pH 7 to 22% at pH 12) besides the main product nitrate. No peroxynitrite formation was detected during ozonation of nitrite-containing waters, suggesting that ^•NO2 is the …

Topographical Mobility Envelope Modeling And Geometric Analysis For Off-Road Unmanned Ground Vehicles, Huashuai Fan

ETDs from 2020-2029

This dissertation introduces topographical mobility as a quantitative framework for assessing off-road unmanned ground vehicle performance based on geometric interaction between the vehicle and terrain. Rather than relying on conventional discrete indices, the proposed formulation evaluates mobility directly from vehicle and terrain geometry, expressing vehicle capability in terms of radius constraints implied by its dimensions and suspension state. On the vehicle side, longitudinal and lateral mobility radii are derived analytically from vehicle geometry—wheelbase, track width, ground clearance, and lowest underbody point location—quantifying the minimum terrain radius negotiable without underbody interference. Suspension state is shown to alter longitudinal mobility radius by …

Reading Between The Lines: An Exploration Of Censorship In United States Public School Libraries, Sally Anne Perz

ETDs from 2020-2029

Between 2021 and 2025, PEN America documented over 22,000 book bans across the United States (US). Yet, with only 451 districts banning out of over 13,000, 97% of US school districts are not engaging in banning. The 451 banning districts represent only 3% of US school districts. While most research examines individual stakeholders, such as librarians and teachers, this study focused on district and community data which do not change as fast as microsystem variables. Since banning occurs at the district level, understanding school district demographics and values may help situate the sociopolitical context of school board decisions to ban …

Evaluation Of Occupational Exposure To Noise And Respirable Particulate Matter In Dentistry, Kabe Fetner

ETDs from 2020-2029

Dental procedures can result in occupational exposures to both noise and particulate matter. Dental professionals routinely operate high-speed instruments and mechanical tools that may produce elevated sound levels and aerosolized particles during clinical treatment. Although these exposures are common in dental environments, limited data exist describing full-shift occupational exposure levels during routine dental procedures. The purpose of this study was to evaluate occupational exposure to noise and respirable particulate matter (RPM) during routine dental procedures in a clinical setting. Area noise monitoring and real-time aerosol monitoring were conducted over six clinical days while common dental procedures were performed, including fillings, …

Statistical Methods For Mendelian Randomization Under Nonlinearity And Non-Normality, Mary Appah

ETDs from 2020-2029

Instrumental variable (IV) methods are widely used for estimating causal effects in observational studies where unmeasured confounding may bias traditional regression estimates. The core idea is to use a variable referred to as an instrument that is associated with the exposure of interest, independent of unmeasured confounders, and influences the outcome only through the exposure. While originally developed in econometrics, IV methods have been increasingly adopted in epidemiology and genetic research under the framework of Mendelian Randomization (MR), where genetic variants, most commonly single nucleotide polymorphisms (SNPs), serve as instruments. MR provides a powerful tool for investigating causal relationships between …

The Role Of Interorganizational Linkages In Shaping Hospital Reporting Burden: A Relational View Analysis, Robert Howard

ETDs from 2020-2029

Administrative burden associated with health information exchange represents a persistent challenge for U.S. hospitals, contributing to provider burnout and operational inefficiency. This study examined whether interorganizational linkages, specifically hospital system affiliation, participation in Accountable Care Organizations (ACOs), and participation in Health Information Exchanges (HIEs), are associated with perceived barriers to electronic health information exchange. Guided by the Relational View, linkages were conceptualized as potential conduits for shared assets, knowledge-sharing routines, and complementary capabilities that might reduce barriers to exchange. Data from 2018–2023 were drawn from the American Hospital Association Annual Survey and IT Supplement, merged with community-level measures from the …

Teacher Culturally Sustaining Practices Supported By Generative Ai: Instrument Development, Guy Trainin, Azadeh Hassani, Shuling Yang

Research and Evaluation in Education, Technology, Art, and Design

Centralized Review Of Alzheimer's Disease And Related Dementias Biomedical Repositories And Computational Methods, Johaan Kathilankal, Kewei Chen, Chen Zhao, Lingtao Chen, Seyedamin Pouriyeh, Zongxing Xie, Yixin Xie

Faculty Articles

lzheimer’s disease and related dementias (ADRD) are neurodegenerative conditions characterized by progressive cognitive and functional decline. AD pathology is associated with extracellular amyloid-β plaques, intracellular tau neurofibrillary tangles, synaptic dysfunction, and neuronal loss. AD accounts for approximately 60–80% of dementia cases globally. In 2022, AD was the seventh leading cause of death in the United States, and the number of Americans aged 65 and older living with Alzheimer’s dementia is projected to increase substantially by 2060. Despite decades of research, AD/ADRD data resources remain fragmented across clinical, imaging, genetic, genomic, and therapeutic domains. This paper addresses that gap by providing …

A Nonenzymatic Electrochemical Glucose Sensor Depending On A Ninps/Co3o4/Functionalized Graphene Oxide-Modified Working Electrode, Sümeyra Pekmez, Muhammet Güler

Turkish Journal of Chemistry

In the present research, the aim was to develop a novel electrochemical enzyme-free glucose sensor dependent upon a nickel nanoparticles (NiNPs)/cobalt (II, III) oxide (Co3O4)/carboxylated graphene oxide (GO-COOH)-modified glassy carbon (GC) electrode. The electrocatalytic performance of the electrode was tested using various electrochemical methods such as amperometry and cyclic voltammetry (CV). The NiNPs@Co3O4/GO-COOH/GC electrode showed noticeably superior electrocatalytic behavior for glucose oxidation in 0.1 M NaOH media, ascribed to the good synergistic impact between NiNPs, Co3O4, and GO-COOH. The amperometric response of the NiNPs@Co3O4/GO-COOH/GC electrode to glucose exhibited two linear determination ranges at +0.55 V potential. The first one was …

Pine Grosbeak (Pinicola Enucleator) Exhibit Collective Vocal Behavior During Foraging Bouts, Stefani A. Crabtree, Thomas J. Crabtree

Environment and Society Faculty Publications

Pine Grosbeaks (Pinicola enucleator) are boreal finches whose winter ecology and social behavior remain only sporadically documented due to their remote distributions and irruptive dispersions. From 18 December 2023 to 6 March 2024, we conducted repeated daily observations of a flock of up to twelve P. Enucleator occupying a temporary wintering range in an urban neighborhood in Oregon. During these observations, we documented a previously undescribed collective vocalization associated with feeding. Comparison with 2674 archived Pine Grosbeak recordings from major bioacoustic repositories revealed that no clear matches between our recording and archives could be established. The low amplitude …
