The Disappearance Of Shannon White, Kathryn J. Limberg

Theses and Dissertations--English

The Disappearance of Shannon White is a Mystery-Thriller novel. The aim of the piece is to explore thematic components including perseverance, socio-economic inequities, the stigmas and medical malpractice of the American mental health system in the late twentieth century, and, ultimately, to entertain. My earliest love in the literary world was science fiction and fantasy. Writers like Robert Jordan, and more recently, Simone St. James, create worlds that test the bounds of reality in a way that I find liberating, and I seek to implement this in my own work. Such authors have taught me that fiction offers freedom to …

Preserving Nature: Mapping Patriarchal And Imperial Control In Victorian Fiction, Hannah Schultz

Theses and Dissertations--English

In Thomas Hardy’s Tess of the D’Urbervilles, a group of fallen women see “themselves and surrounding nature forming an organism of which all the parts harmoniously and joyously interpenetrated each other” (65). As relational, boundary-dissolving, ecological subjects, these women are empowered above society’s judgment, made “sublime as the moon and stars” (65). By analyzing such representations of ecological relationality in Victorian fiction, my dissertation reveals new forms of agency for women and racialized others. While many ecofeminists have historically disavowed the nature-gender link as reinforcing the shared oppression of nature and marginalized groups, I depart from this standpoint, as …

Feeling And Experience In American Women's Writing From The First World War, Anika Jensen

Theses and Dissertations--English

This dissertation analyzes the political capacity of feeling in American women’s autobiographical and semi-autobiographical writing from and about their work during the First World War. Women produced emotionally complex accounts that resist easy categorization, and I argue that attending to feeling clarifies not only their emotional experiences with war work but their social and political projects. This dissertation closely examines portrayals and rhetorics of feeling, considering the intersections of gender, class, race, and labor in impacting how feelings are depicted, negotiated, and conveyed. While British women were more compelled to perform and convey feeling according to a rigid class system, …

Geochemical And Sedimentological Signals Of Bottom Water Oxygen Dynamics From Lake Tanganyika (Zambia), Njahi Mwangala

Theses and Dissertations--Earth and Environmental Sciences

Lake Tanganyika is a large, ancient freshwater body with exceptional biodiversity that is located in the East African Rift System. Lake Tanganyika’s size and longevity make its sedimentary record useful for understanding environmental changes that cross spatial and temporal boundaries. Lake Tanganyika is known to be susceptible to global warming given its tropical location. Over 12 million people living within Lake Tanganyika’s watershed rely on fishing for their income and nutrition. Changes to limnological function driven by climate could therefore have serious implications for human health and biodiversity conservation. This study focuses on using geochemical properties of modern lake bottom …

Multi-Scale Analysis Of Karst Aquifer Vulnerability To Climate Change And Contamination Processes, Shishir Sarker

Theses and Dissertations--Earth and Environmental Sciences

Karst aquifers represent some of the world’s most productive yet vulnerable groundwater systems, supplying freshwater to approximately 10% of the global population across 15% of Earth’s ice-free land surface. Their distinctive hydrological characteristics— including rapid recharge, preferential flow paths, and limited natural filtration— create unique vulnerabilities to both climate variability and contamination that pose significant challenges for sustainable water resource management. This dissertation presents a comprehensive multi-scale analysis of karst aquifer vulnerability through three interconnected studies that examine climate change impacts, microbial contamination dynamics, and contaminant transport processes across diverse geographic and hydrogeologic settings.

Chapter two investigates climate change impacts …

How To Eat Right And Why We Ask That Question, Heather N. Carpenter

Theses and Dissertations--Gender and Women's Studies

What does it mean to “eat right?” The notion is, of course, culturally, historically, nationally, politically, ethnically, and class determined. For the purposes of this project, however, I am particularly interested in changing notions of what it means to “eat right” within the post-World War II to the early new millennium American context, as such notions are represented within the prescriptions of popular culture. I turn to popular culture because this is the commons of the hegemonic call to “normalcy”—this is where we all learn to imitate, aspire, or rebel against a generic American consumer-self in conformity with the biases, …

Plastic Gerontologies: Epigenetic Clocks As Instruments Of The Profitable Medicalization Of Aging, Hans T. Purisch

Theses and Dissertations--Geography

Epigenetic clocks are algorithms that use epigenetic biomarkers of aging to calculate an organism’s ‘biological age.’ Through discursive analysis of commercially available epigenetic clock marketing materials, scientific articles, and interviews with actors in the longevity biotechnology industry, this study examines the commercialization of epigenetic clocks in the form of consumer test-kits. The study argues that longevity biotechnology companies leverage the malleable and fluid qualities of epigenetic markers of biological age to extend the domains of profitable therapies. It shows that epigenetic clock companies market the dynamic qualities of epigenetic biological age measurements to redefine health around the project of optimizing …

Woke-Lahoma: Anti-Trans Ideology On The Frontlines, Sarah H. Fogel

Theses and Dissertations--Geography

The past decade (2015-2025) of American politics has been marked by a sharp rise in anti-trans politics. Indeed, during this period, anti-trans rhetoric and legislation have become central to American conservative politics more broadly. As the Republican party under Donald Trump works daily to remake the federal government in its image, studying the recent past of Republican-controlled states like Oklahoma offers a window into the future of anti-trans politics at the national scale. This thesis uses a mix of discourse analysis of anti-trans media and participant observation at 2SLGBTQ+ Pride events to analyze the ideological underpinnings of the present-day anti-trans …

Findings show that the HCJM does more than exhibit art, it demonstrates how art can be leveraged to advance both activist and educational projects. This study positions the HCJM as a model for how local and justice orientated museums and cultural spaces can contribute …

Making Slums Legible, Visible And Calculable: Geospatial Technologies And The Governance Of Urban Land In Mumbai, Sanjana Krishnan

Theses and Dissertations--Geography

This dissertation examines how geospatial technologies are used to make slums in Mumbai legible, calculable, and hypervisible, and how these practices reshape urban land governance. It situates mapping, remote sensing, and algorithmic systems within their political-economic contexts, showing how technologies intending to see the city often function as instruments of dispossession. The research has three interconnected empirical chapters. The first empirical chapter traces the history of slum mapping in Mumbai, from their absences in early development plans to their selective hypervisibility under the contemporary governance regimes. Using critical cartographic methods, it highlights how novel technologies such as remote sensing, biometric …

Trashing Gender Scripts: Indexical Misrecognition In The Zine "Galatea's Naked", Jules Blank

Theses and Dissertations--Linguistics

Zines, short for ‘fanzines’ or ‘magazines,’ refer to physical, printed, self-published creations that can consist of a single sheet of paper or many, fastened together. These artifacts are rich with meaning—and, thus, can be read as tangible manifestations of the ideologies and identities of the creator(s).

This thesis focuses on the way zines are used as tools of resistance. Additionally, it shows that the creation and circulation of zines are highly pragmatic acts that solidify social bonds and enable individuals to perform and reinforce their emergent identities within a collective—explicitly making a claim about who they are and what they …

Shaping A City: Municipal Housekeeping, Civic Activism, And Urban Environmentalism In Progressive Era Louisville Through The Women’S City Club, Amy J. Malventano

Theses and Dissertations--History

At the turn of the twentieth century, rapid industrialization and urban expansion transformed American cities, creating urgent challenges in governance, public health, and environmental management. In response, women across the United States extended their domestic expertise into the public sphere, spearheading initiatives to improve sanitation, waste disposal, and urban infrastructure. This dissertation examines the Louisville Women’s City Club (LWCC) as a case study of municipal housekeeping, demonstrating how middle-class women used their traditional roles to influence systemic reform in Louisville, Kentucky. By bridging gender history, urban environmentalism, and Progressive Era activism, this study reveals how the LWCC shaped public policy …

“A True And Broad Sympathy:” Thomas Hughes, Medievalism, And Social Justice In The Nineteenth Century, Sarah E. Stapleton

Theses and Dissertations--History

Thomas Hughes, author of Tom Brown’s Schooldays (1857), used medievalism to help solve social problems of the Nineteenth Century. This contravenes the traditional view of medievalism, especially Anglo-Saxonism, since others have used it to justify the subjugation of people of lower social status, namely the poor in England, enslaved African Americans in the United States, and Indians under British rule.

While the use of medievalism is veiled in Hughes’ work, the subtext of Tom Brown’s Schooldays demonstrated Hughes’ Anglo-Saxonism. Tom Brown and the intertextual material surrounding his narrative exhibit the characteristics of Anglo-Saxonism through cultural primitivism, the concept of allodial, …
