Textual Sediments: Genre And The Planetary Novel, William Bowden

Open Access Dissertations

This dissertation investigates how twenty-first-century prose fiction navigates the ecological and temporal dimensions of planetary crisis. In response to accelerating pressures - climate change, ecological collapse, and the intensification of capitalist modernity - literary studies has turned increasingly to the planetary as a conceptual frame. Yet this shift has often outpaced the development of adequate critical vocabularies and narrative methodologies. By drawing on ecocriticism, narrative theory, phenomenology, and related fields, Textual Sediments proposes a new framework for reading what it terms the planetary novel: a sedimentary genre characterized by temporal layering, formal hybridity, and a recursive engagement with scale. Through …

Community Belonging: Experiences Of Outsiderness In Appalachia, Erin Hudnall

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study demonstrates the potential long standing social impacts of extractive industries in Appalachia, supported by historical data and literature that defines the region as a sacrifice zone or as resource cursed. As represented by key informants and the communities under observational study, West Virginia communities can exhibit dynamics indicative of collective trauma that is emplaced and complex in nature, given a historical high level of industrial intervention and social control that induced precarious economic, environmental, and social circumstances. Some of the main “symptoms” of this collective trauma are an aversion to outsider intervention and nostalgia about the past that …

International Students’ Perceptions And Experiences Of Institutional Diversity Initiatives And Self-Authorship Attainment: A Mixed Methods Study, Sandra Ayivor

Graduate Theses, Dissertations, and Problem Reports (ETD)

Higher education institutions in the United States have responded to years of discrimination through several diversity initiatives. Although research has indicated the merits of such initiatives on student development, the outcomes are not uniform across all student populations. Moreover, student development discourses have often excluded the experiences of international students. Employing a convergent mixed methods approach, this study investigated the perceptions and experiences of international students at a flagship land-grant higher education institution in the Appalachian region of the United States regarding institutional diversity initiatives and their self-authorship based on some demographic characteristics (i.e., gender, age, marital status, religion, continent, …

Apostrophes And Archimedes, Evan J. Clough

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis explores how digital collage and printmaking can be used to develop images through acts of subjective response, intentional and unintentional acts of appropriation, and parodic re-use and comparison pushed to absurd extremes. It looks at the history of creating art for parodic re-use and examines “Pataphysics”, developed by and for art appropriation of pattern, form, and process. These concepts are explained and related to visual artwork that was made for the thesis exhibition Apostrophes and Archimedes Cast Shadow Puppets. The exhibition invites viewers to experience the phenomenon of observation, automatic transformation, and creation using multiple modalities of exaggerated …

This qualitative study employs narrative case study to center the lived experiences …

Pluralism In State Constitutional Law, Michael L. Smith

Georgia Law Review

Debates over constitutional interpretation rage on—with most parties staking out preferred theories, their justifications, and assertions of their utility in predicting, explaining, and critiquing court opinions. The United States Constitution and the Supreme Court take center stage, despite a rich set of cases and constitutions at the state level. At the same time, state constitutional discussions tend to steer clear of federal interpretive theorizing.

This article seeks to bridge the gap between these literatures, arguing that state constitutional interpretation practices demonstrate a pluralist approach that may inform broader theoretical debates. State courts frequently employ different methods—sometimes explicitly, sometimes implicitly—both across …

A Comparative Case Study Of Learners Experiencing Interdependent Empowered Care In Marginalizing Contexts, Elizabeth Gil

GSE Faculty Publications

This comparative case study’s purpose is to explore how multi-age learn-
ers, both adults and children, from immigrant backgrounds experienced
care in two educational settings in the United States and Ireland. Using
data from two separate qualitative studies, this paper draws on the
authors’ conceptualization of interdependent empowered care (IEC) to
argue that the settings exemplified three separate, but interrelated, care
elements: 1) identity-affirming counterspaces; 2) interdependency and
reciprocity; and 3) a means to achieve greater empowerment and agency.
This cross-national study illuminates the role of care in educational set-
tings to understand how it helps multi-age learners from immigrant …

1 Of 84 The Discursive Tactics Of Perpetuating White Normativity In Public Education: A Critical Policy Discourse Analysis Of Anti-Crt Policies Across 18 States, Alison Wilson, Alissa Blair, Jason L. Endacott, Christopher Giller, Christian Z. Goering

Curriculum and Instruction Faculty Publications and Presentations

In recent years, state policies banning "divisive concepts" have proliferated as part of a coordinated effort to undermine racial justice by framing critical discussions of race as "indoctrination" and imposing ideological restrictions on curriculum and pedagogy. Using critical policy discourse analysis informed by a critical study of whiteness, this paper examines how 22 policy documents from 18 states operate discursively to shape the parameters of race-related discourse in public education. Our findings suggest that these policies employ three primary discursive maneuvers: (1) constructing false equivalencies that equate white discomfort with racial oppression, (2) appealing to "universal" values to obscure systemic …

Books As Windows And Mirrors: A Catalyst For School Belonging In The Middle Grades, Kaitlin Mary Smith

Theses & Dissertations

Adolescents today are reading for leisure at historically low rates and are experiencing increased mental health challenges, such as anxiety, depression, and loneliness. However, research shows that students who engage in reading tend to report having better mental well-being. A strong sense of school belonging—the feeling of being accepted, valued, and connected within the school environment—plays a crucial role in how students engage academically and their overall mental health. For students from historically marginalized groups and diverse backgrounds, it is especially challenging to find reading material that authentically represents their sociocultural identities. This explanatory sequential mixed methods study aimed to …

Contextual Augmentation In Artificial Intelligence, Emmanuel Joshua Balogun

College of Graduate Studies: Theses & Dissertations

Contextual understanding is a significant challenge of Large Language Models (LLMs), which are typically trained on general-purpose datasets. Due to this, LLMs fail to capture nuanced or domain-specific information and may struggle to interpret user queries accurately. Consequently, prompt engineering can become complex in automating, and LLMs are prone to “hallucinating”—generating random or irrelevant texts—when they lack sufficient context. This undermines their ability to provide focused, accurate responses. Accordingly, this thesis seeks to enhance the contextual understanding capabilities of Artificial Intelligence systems to facilitate more precise and relevant answer generation. Study A looks into a new approach to combating misinformation …

The School Of Becoming: Speculative Essays On Existential Possibility And Humanity In Education, Timothy A. Holman

College of Graduate Studies: Theses & Dissertations

This dissertation reimagines public education through an existential lens, advocating for a humanitarian approach that resists the prevailing dominance of standardized, data-driven systems. Drawing primarily from the philosophy of Jean-Paul Sartre (1936, 1940, 1943, 1947, 1965, 1992), it contends that education should honor freedom, nurture authenticity, embrace encounters with others, and cultivate imagination as essential to human development. Influenced by the works of William Ayers (1998, 2004, 2008, 2016, 2024), Maxine Greene (1967, 1973, 1978, 1988, 2000, 2001), Paulo Freire (1970, 2001, 2004), Christopher Emdin (2010, 2016, 2021), and Byung-Chul Han (2018, 2024), speculative essays—each focused on an existential theme—are …
