Research shows that students who suffer from mental illness, such as anxiety and depression, fear their condition will be perceived negatively by their peers and professors. The literature also suggests that U.S. colleges and universities can be more proactive in offering students resources for their mental health concerns to decrease anxiety and depression. It appears that absent or limited mental health resources have failed to address rising cases of student mental illness, and more specifically, …

“It Could Have Happened To Any Of You”: Post-Wounded Women In Three Contemporary Feminist Dystopian Novels, Abby N. Lewis

Electronic Theses and Dissertations

My goal for this thesis is to investigate the concept of (mis)labeling female protagonists in contemporary British fiction as mentally ill—historically labeled as madness—when subjected to traumatic events. The female protagonists in two novels by Sophie Mackintosh, The Water Cure (2018) and Blue Ticket (2020), and Jenni Fagan’s 2012 novel The Panopticon, are raised in environments steeped in trauma and strict, hegemonic structures that actively work to control and mold their identities. In The Panopticon, this system is called “the experiment”; in The Water Cure, it is personified by the character King and those who follow him; …

The Tangled Roots Of The Holocaust: An Analysis Of The Evolution Of Colonial Discourse Through The Prohibition Of Sexual Relations And Marriages Between Races, Bianka Adamatti

Electronic Theses and Dissertations

The Nazi violence did not have its origins only in the brutality of the First World War or radical nationalist ideologies, but also in European colonialism. Hence, the goal of this thesis is to demonstrate that colonial processes were fundamental to the origins of the Holocaust. To prove this, I applied the content analysis to detect colonial discourse (stereotype, ambivalence, and mimicry) in three legislations from different contexts, which prohibited sexual relations and marriages between races. The documents analyzed exemplified the segregationist thinking of each period of colonization. Portuguese laws from the beginning of modernity demonstrate the transition from religious …

Fanfiction: A Look Into The Disruptions Of Gender Identity Through Tropes, Stephanie Preslar

Electronic Theses and Dissertations

Fanfiction provides the unique opportunity to explore disruptions of heteronormativity through tropes. By exploring different fanfictions in the Soulmate AU, ABO Dynamics, and Mpreg tropes, the disruptions indicate a desire to explore gender, identity, and sexuality through queered characters. Male slash fanfiction provides the chance to examine the disruption of the heteronormative through the queering of male characters and placing them into situations that may embrace the feminine or a female-gendered experience. The situating of heterosexual male characters into queered roles allows an examination of how this disrupts canonical ideas of gender, identity, and sexuality. By reviewing the male slash …

From Byronic To Gothic Blood Sucker: Subversion Toward A Non-Gendered Identity, Hannah Hoover

Electronic Theses and Dissertations

Analyzing Emily Bronte’s Wuthering Heights and linking trends of the Byronic hero that have merged into a variety of genres reveal that the hero is a mode of subversive gender expression, which has evolved within the Gothic through feminine desire. Delving into Bram Stoker’s Dracula will provide unique insight into the audience’s desires/expressions of gender. Finding the transition point from the monster vampire of Dracula to Stephanie Meyer’s desirous, sparkling boy-next-door in Twilight will track the trajectory of gender and sexual norms through time. From the foundational adaptation of the Byronic hero in Wuthering Heights to the repressed vampiric desire …

Intuition Of An Outsider: From Nothing To Voice In George Scarbrough’S Poetry, William Moore

Electronic Theses and Dissertations

Long acknowledged as a committed poet of place, this thesis examines tones of outsiderness and alienation that characterize George Scarbrough’s poetry. Scarbrough draws on familiarity with his childhood in southeast Tennessee, and from an outsider’s outlook, a perspective veritably prompted by the rejection he suffered as a homosexual and lover of language, Scarbrough’s poetry addresses the daunting themes of fear and nothingness. Analysis of his poetry also reveals qualities of hope and endurance, a commitment to received forms, and Modern innovation. Through his poetic voice, culminating in the alter ego of Han-shan, Scarbrough provides vital insights into the human experience.
