Dredging The Wetlands, Tilling The Field: Ecotonal Poetics Of The Anthropocene, Stacey Balkun

Electronic Theses and Dissertations

This dissertation interrogates the use of poetic fragmentation as a tool of ecological representation and coins the term “ecotonal poetics.” Ecotonal poesis, this dissertation explains, is the stretching of lyric across the field of the page, using space, sound, language, and parataxis in its attempt to not only represent but create ecotonal ecologies through text, sound, and visual cues. This dissertation puts forth four case studies of contemporary American women poets turning the space of the page into an ecotone where text, white space, author, reader, body, and environment meet. The poets studied here rely heavily on textual experimentation, suggesting …

The Role Of Impulsivity In Relation To The Co-Occurrence Of Binge Eating And Binge Drinking, Hannah Holst

Electronic Theses and Dissertations

Binge eating and binge drinking often co-occur, but the role of impulsivity in accounting for this relationship is under-investigated. Existing research acknowledges shared risk factors, yet the specific impact of impulsivity is a critical gap. Impulsivity, characterized by impulsive decision-making, is known in addictive behaviors. This research with a sample of college and community participants assessed binge eating, binge drinking, and impulsivity. Overall, binge eating and binge drinking were uncorrelated, contrary to previous research. However, impulsivity was associated with both binge eating and binge drinking. Gender differences were also noted, along with differences between the community and college samples. The …

Authentic Fake: Authenticity And Authentication., Suyun Son

Electronic Theses and Dissertations

My thesis exhibition questions the modern sanctification of authenticity. No longer believing in objective truths, the postmodern society seeks epistemic grounding on being true to oneself. The categories of authentic-or-fake replaced the binary of true-or-false. But authenticity is a trojan horse for authentication. As a Korean American artist, I'm encouraged to express my “authentic” Korean identity. This encouragement can also imply my works will receive recognition as authentic and meaningful only when they embody Korean cultural expression. Authenticity becomes a performance for the sake of authentication. Ironically, authenticity turns into an act of conformity/confirmation. Authenticity demands you stay true to …

W.E. B. Du Bois And Audre Lorde's Pan-African Development: Remedies For The Problem Of Othering., J.E. Young

Electronic Theses and Dissertations

W.E.B. Du Bois and Audre Lorde’s Pan-African Development: Remedies for the Problem of Othering is an Afrocentric reading of Black U.S intellectual traditions of self-definition from the late 19th to early 21st century. I argue that W.E.B. Du Bois and Audre Lorde adhered to two major Afrocentric principles: balance and justice. At the root of these principles is the understanding that binaries constructed as oppositions create unjust hierarchies. My theoretical approach is attuned to the distinct ways that Du Bois and Lorde communicated the importance of self-definition and Africana spirituality in relationship to other Black intellectual thought. Placing them in …

Investigation Of Avaren-Fc's Therapeutic Potential Against Ovarian Cancer., Katarina Lee Mayer
