From Surface To Subtext: Portrayals Of Success In Superfund Remediation., Haley Metcalf-Wade

Electronic Theses and Dissertations

Superfund sites represent some of the most contaminated and environmentally sensitive areas in the United States. How these sites are portrayed can significantly influence public perception of environmental risks, the effectiveness of remediation efforts, and the overall state of environmental health. Regulatory agencies like the Environmental Protection Agency (EPA) are entrusted with safeguarding public health and the environment. How they communicate about their actions, successes, and challenges directly impacts public trust and perceptions of their accountability. This dissertation examines the manifest and latent metrics used by the Environmental Protection Agency (EPA) to determine success in Superfund remediation by focusing on …

Transatlantic Memory And Identity: The Legacy Of Colonel Heg And The 15th Wisconsin In Norway And Norwegian America, Remi Berg

Electronic Theses and Dissertations

While memory studies of the American Civil War flourishes, ethnic and immigrant perspectives remain obscured. This project attempts to uncover how Norwegian-Americans remembered the 6000 Norwegian immigrants who fought in the Union Army. It explores the processes behind commemoration of Colonel Hans Christian Heg and the 15th Wisconsin Infantry Regiment from 1914 to 1928. It reveals that Norwegian-Americans commemorated Colonel Heg on three different and connected levels. Nationally, Norwegian-Americans raised a statue of Heg in Wisconsin after the individual determination of Waldemar Ager to challenge nativism and Americanization. Transnationally, Ager cooperated with the organization Nordmands-Forbundet who facilitated the erection of …

Enhancing Ethical Competency: A Review Of Ethical Instruction For Law Enforcement, Alexis Turner

Electronic Theses and Dissertations

As public confidence in policing has dropped, demand for ethical behavior from law enforcement officers has grown, and correspondingly, a better understanding of ethics training and ethical acquisition processes has become paramount. Though much literature exists on related topics, understanding of the ethics training for law enforcement officers as it currently exists, has remained murky. This research aimed to gain a better understanding of ethics training for law enforcement in the United States, and as such, to fill the aforementioned gap in the literature. Four research questions were explored in this study including the understanding of current pre-service and in-service …

Harry Potter And The Immersive Space: A Rhetorical Analysis Of The Wizarding World Of Harry Potter, Kendra Bolin

Electronic Theses and Dissertations

The ability of humans to share stories has changed over time. From myths shared around a campfire to the introduction of cinema, we can now tell massive, immersive stories on an epic scale. One example of this is the storytelling present in theme parks. Present-day theme parks are continuously growing and expanding each year both in size and attendance. The continued success of these theme parks and the rhetorical influences of their audiences is a cultural phenomenon that deserves rhetorical scrutiny. My analysis looks at how one theme park, the Wizarding World of Harry Potter in Orlando, Florida, immerses guests …

Unraveling The Complex Dynamics Of Cardiac Fibrosis: Ccn1 As A Novel Regulator Of Scar Collagen Architecture And Structural Integrity In Myocardial Infarction., Annalara Garland Fischer

Electronic Theses and Dissertations

Expansion of the extracellular matrix (ECM), known as fibrosis, accompanies nearly all forms of cardiac disease; however, its most significant and complex manifestations arise following a myocardial infarction (MI). This process, principally led by fibroblasts, constitutes a necessary and adaptive response acutely to fill the void from cardiomyocyte necrosis following ischemic injury due to the heart’s lack of regenerative capacity. This acute response never fully resolves and contributes to ongoing collagen accumulation in non-infarcted regions, leading to diminished ventricular compliance, ongoing myocyte loss, and attrition in function—culminating in heart failure. Further, recent research demonstrates that concomitant with progressive increases in …

Exosomal Cannabidiol: A Promising Candidate For Targeted Oral Delivery Against Breast Cancer., Disha Nagesh Moholkar

Electronic Theses and Dissertations

Cancer therapies are limited by lack of specificity, selectivity and numerous adverse effects. Repurposing potential anticancer compounds with appropriate drug carriers can help overcome these drawbacks. In our present study, we address the major obstacle for cannabidiol (CBD): its low oral bioavailability, using exosomes. Exosomes (Exo) are promising non-toxic and biocompatible drug delivery vehicles Our project aims are to address the research gap by formulating exosomal cannabidiol (ExoCBD): a tumor-targeted oral delivery system for the treatment of breast cancer. The targeting approach relies on the overexpression of folate receptors at the tumor site by using folic acid functionalized exosomes (FA-Exo). …

Venturing In Limbo: Entrepreneurial Resourcefulness By The Forcibly Displaced., Sadek Showkat

Electronic Theses and Dissertations

Entrepreneurial resourcefulness is an overarching concept in the entrepreneurial process that has gained momentum among theorists and practitioners. Traditionally, entrepreneurial resourcefulness is theorized as a state—a behavior or trait—rather than a process. However, our understanding of this concept changes significantly when viewed through the lens of the lived experiences of forcibly displaced individuals. This dissertation presents a theoretical and empirical investigation of how these entrepreneurs pursue entrepreneurial resourcefulness through three interrelated essays. The first essay provides a problematizing review and introduces a novel typology (exogenous vs. endogenous) that captures the heterogeneity of the construction of entrepreneurial resourcefulness across …

Contested Spaces: Unhoused Black Men And Their Survival Within The Urban Landscape., Jonathan Riley Ellis

Electronic Theses and Dissertations

Thousands of unhoused Black men sleep, live and eat on the streets daily. Many lack the essential resources to survive through the elements. However, little is known about how unhoused Black men share space with the public, businesses, law enforcement and each other. Furthermore, little is known about how unhoused Black men access services once displacement has occurred. Drawing on participant observation and in-depth interviews, I examine how unhoused Black men navigate occupied urban spaces. I find that unhoused Black men regularly encounter contested spaces with businesses, the public, hospitals, and law enforcement. Additionally, unhoused Black men must navigate through …

Deep Reinforcement Learning-Based Dynamic Routing And Spectrum Access In Aeronautical Networks., Zhe Wang

Electronic Theses and Dissertations

As the airspace is experiencing an increasing number of aircraft, spectrum sharing among Air Vehicles (AVs) and Terrestrial Users (TUs) emerges as a compelling solution to improve spectrum utilization efficiency. I investigated three types of aeronautical communication including the single-hop Air-Air Communication Network (AACN), the multi-hop Air-Air Ad-hoc Network (AAAN), and the Aerial and Terrestrial Hybrid Network (ATHN). I assume a spectrum-limited scenario through all communication networks. Thus, the number of communication pairs is greater than that of the available channels, resulting in co-channel interference due to the reuse of the same channel among communication links. In a single-hop AACN, …

Bayesian Approaches In Multi-State Markov Models And High Dimensional Time-To-Event Data., Yuchen Han

Electronic Theses and Dissertations

This dissertation consists of two projects. The first one involves nonparametric methods on Continuous Time Markov Chains (CTMCs). The second one is centered around Bayesian shrinkage models for detecting prognostic and predictive biomarkers in high-dimensional clinical data. Both these projects build on methods from across the frequentist and Bayesian paradigm to offer novel solutions. In the first project, we aim to model the nonlinear effects of continuous variables within multistate framework in a non-parametrically by appealing to the rich mathematical framework of Reproducing Kernel Hilbert Spaces (RKHS). Then we adapted the classical Representer Theorem to penalized (squared norm) log-likelihood which …

Health Professions Education And Critical Action Engagement: A Mixed Method Analysis., Leonda Richardson

Electronic Theses and Dissertations

Poorer health outcomes disproportionately impact racial/ethnically minoritized (e.g., Black Indigenous People of Color, or BIPOC) populations in the U.S. One plausible reason for the persistence of poorer health outcomes among this population is the teaching of racialized curricular content within academic health professions programs. This includes the absence of appropriate context through explicit socio-political curricular content (SPC) and critical pedagogy (i.e., social and structural determinants of health, history of racism in health care, social justice concepts; dialogue and reflective writing). Racialized curriculum is thought to initiate and/or exacerbate existing racial biases, cultural incompetence, and perpetuate dominant medical ideologies and myths …

Molecular Mechanisms Of Exercise-Stimulated Resolution Of Inflammation And Its Dietary Dependence., Ernesto H. Pena Calderin

Electronic Theses and Dissertations

Diet-induced obesity and adipose tissue (AT) inflammation that ensues sets the stage for systemic metabolic inflammation, disrupted insulin signaling, and eventual type 2 diabetes (T2D) development. At the center of this pathology lies a disruption in endogenous inflammation resolution pathways characterized by an imbalance in lipid mediator production (greater abundance of pro-inflammatory to pro-resolving lipids). Additionally, obese states are characterized by adrenergic deficiency, especially in response to physical activity. Inflammatory processes have been experimentally mitigated by either the pharmacological inhibition of pro-inflammatory signals (i.e., Leukotriene B₄ (LTB₄) and its receptor BLT1, which establishes a potent chemotactic stimulus …

Development And Processing Of Shape Memory Polymer Composites (Smpcs) For Application In Structural Robotics And Robotic Sensors., Kavish Sudan

Electronic Theses and Dissertations

Shape Memory Polymers (SMPs) have attracted significant attention since their introduction in the 1980s due to their remarkable ability to regain their original shape from a temporarily deformed state when exposed to an external stimulus, typically heat. This shape memory effect, driven by thermal transitions such as the glass transition temperature (T_g) or melting temperature (T_m), has made SMPs highly attractive for applications in soft robotics, aerospace, and biomedical devices. However, SMPs face challenges such as limited mechanical strength, thermal stability, and electrical conductivity, which hinder their broader adoption in advanced applications. To address these challenges, …

Coproduction, or the interaction of citizens with their public service provider, has been used in policy responses to a myriad of service delivery problems, especially policing. This dissertation uses a three-manuscript approach to revisit coproduction both as a theory and a practice. The first manuscript tracks the evolution of coproduction as a theory from three different disciplines: economics, urban theory, and public administration. In addressing the three disciplines, the manuscript explains what broadly united the coproduction literature and the differences that hindered the early development of the concept. It concludes with how the concept is used today, and how future …

Exploring Chronic Stress, Avoidance Coping, And Diurnal Cortisol In Head And Neck Cancer Patients: A Pilot Study Of Best Practices In Diurnal Cortisol Sampling., Brooks R. Harbison

Electronic Theses and Dissertations

Cancer patients are vulnerable to the deleterious effects of chronic stress, especially those prone to avoidance coping. Research in the general population has linked these effects to aberrant diurnal cortisol. However, the current literature on cancer patients has shown inconsistent results in associations between chronic stress, avoidance coping, and diurnal cortisol, possibly due to inconsistent cortisol sampling practices. This pilot study of head and neck cancer patients aimed to address this gap in the literature by implementing best cortisol sampling practices to investigate the links among chronic stress, avoidance coping, and diurnal cortisol slope, average bedtime cortisol, and average wake …

Radical Hospitality: Height And Excess Of The Other And The New Host Self, Diako Alikhani

Electronic Theses and Dissertations

Drawing on Emmanuel Levinas’ ethical framework and its emphasis on the “height and excess” of “the Other,” this thesis explores and develops a sense of “radical hospitality” in Levinas and across Judaism, Christianity, and Islam. In particular, the thesis explores how encounter with the Other is not only marked by an overwhelming excess, but one which transforms the subject into what I call a “New Host Self:” Where the self is the host who greets the stranger with hospitality, it is ultimately the stranger—the refugee, the migrant—who transforms the host into someone new. Here, the host ultimately receives a gift …

Honoring Indigenous Worldview: Cultural (Un)Responsiveness In Gifted Education, Vicki Boley

Electronic Theses and Dissertations

Many working understandings of giftedness exist within dominating Western frameworks, gatekeeping gifted education from students who do not “fit” inside such frameworks (Owens et al., 2018; Rinn et al., 2020; Sternberg et al., 2021). As a result, K- 12 Native American, Alaska Native, and Native Hawaiian students are underrepresented in gifted education programs (Sternberg et al., 2021) and overrepresented in special education programs (NCLD, 2023). When considering Indigenous students in particular, Western orientations surrounding giftedness perpetuate assimilation, dominance, and continued colonization (Battiste, 2013; Dunbar-Ortiz, 2014; Gentry & Gray, 2021a). Leveraging Positionality and The Pedagogy of Listening as conceptual frameworks, this …

Evidence Of Climatic Influence On Subsistence Strategies At Sage Hen Springs, Nevada, Andrew Rogers

Electronic Theses and Dissertations

Models of settlement patterns in the northwest Great Basin describe a decrease in residential mobility, intensified use of upland spring ecozones, and an increase in diet breadth during the Middle and Late Archaic. Here, I present data collected from the Sage Hen Springs site in northwestern Nevada during a Phase II testing project conducted by the BLM and an analysis of these data focusing on patterns of subsistence and mobility strategies throughout the Archaic. Results of this analysis support existing models of lifeways in the northwest Great Basin at the small scale and point to climatic factors as influences on …

Picturesque Portraiture: The Composition Of Reality In Hawthorne, Melville, And James, Angela Michael Gattuso Densmore

Electronic Theses and Dissertations

Throughout the nineteenth century, American artists were tangled in debates regarding the representation of reality. The Hudson River School of picturesque landscape painters tackled this dilemma with a compromise formula which used the real objects of nature to create ideal scenes. This dissertation applies the same picturesque formula to select examples of literary portraiture, studied under the concept of “picturesque portraiture.” Whereas the Hudson River compromise resulted in an ideal perception of reality, however, the picturesque portraits composed by nineteenth-century authors Nathaniel Hawthorne, Herman Melville, and Henry James attempt to invoke a non-idealized “actual” reality of the portrait subject’s person …

Neuroinflammation In Alzheimer’S Disease Mouse Brain Following Repetitive Mild Traumatic Brain Injury, Lujain Almuhanna

Electronic Theses and Dissertations

Traumatic brain injuries (TBIs) are a common form of head injury, with mild TBIs (mTBIs) making up 75-90% of the TBI severity scale. It’s been suggested that repetitive mild TBIs (rmTBIs) may enhance effects of Alzheimer’s Disease (AD). With dementia linking TBI and AD together, we investigated the memory hub of the brain - the hippocampus. Astrocytes and microglia are two glial cells that respond to neuroinflammation and therefore imaged in hippocampal regions of the 3xTg-AD mouse brain. We hypothesized that AD brain pathology (i.e., neuroinflammation) would be accelerated in 3xTg-AD mice following rmTBIs early in life. Analyses revealed that …
