Examining not only mere representation of young transgender and gender variant people, Sandercock explores the intersections of gender and various vertices of …

Literacies Of The Rainbow Corn Mother: A Queer Indigenous Eye For Dei, Paul David Terry, Jamal Epperson

International Journal of Human Rights Education

The landscape of Diversity, Equity, and Inclusion (DEI) work is currently undergoing a critical evaluation and facing attacks, revealing the limitations of performative initiatives entrenched in colonial frameworks. These initiatives often fail to acknowledge and address the erasure of Indigenous and queer identities, alongside the need for genuine representation within institutional settings. This approach may lead to creating inclusivity shaped by colonial law rather than fostering the true inclusivity and belonging that communities seek.

Advocates are calling for a shift towards a more comprehensive and inclusive approach to DEI work, urging organizations to move beyond performative gestures and toward meaningful …

The Blinding Lights Of (Post)Feminist Empowerment In Joyce Carol Oates’S "Night, Neon”, Stéphanie Maerten

Bearing Witness: Joyce Carol Oates Studies

Juliana, the protagonist of Joyce Carol Oates’s 2018 novella “Night, Neon,” is portrayed as a confident, empowered young woman who appears to embody the postfeminist ideal of “having it all”—autonomy, agency, and adherence to traditional feminine norms like marriage and motherhood. However, as the story unfolds, it becomes evident that Juliana’s sense of empowerment is largely performative, concealing deep-seated vulnerabilities and unresolved traumas. Through a series of flashbacks revealing Juliana’s troubled past, Oates critiques the postfeminist tendency to reinterpret traumatic experiences as tools for self-empowerment and resilience, suggesting that such a framework may obscure the systemic and pervasive nature of …

The Mudwoman In The Academia: The Spectral Presence Of Jane Eyre And Antoinette Cosway In Joyce Carol Oates's Mudwoman, Stéphanie Durrans

Bearing Witness: Joyce Carol Oates Studies

While Jane Eyre has been lauded as a feminist novel, its modernist prequel Wide Sargasso Sea clearly aims at recovering the lost voice of the much-maligned Bertha Rochester from an altogether different feminist perspective. In her 1985 essay on these two novels, Joyce Carol Oates highlights their dual relationship in terms of romance and anti-romance, regarding Rhys’s novel as “a reverse mirror image of Jane Eyre’s and Rochester’s England.” Commenting upon the brief encounter between Jane and Rochester’s first wife as depicted by Jean Rhys, Oates also points out that, “[i]nhabiting contrary worlds, one woman is a savage to the …

Joyce Carol Oates And Feminism: Facts Found And Foundered, Gavin J. Cologne-Brookes

Bearing Witness: Joyce Carol Oates Studies

This essay explores the nuanced relationship between Joyce Carol Oates and feminism, distinguishing between Oates as an individual and “JCO” as the authorial process. Through analysis of novels like Babysitter, the essay argues that Oates’s fiction resists fixed labels, instead foregrounding ambiguity, interpretation, and the limitations of categorization. Drawing on philosophical and literary contexts, it contends that while Oates’s work invites feminist readings, her narrative style deliberately undermines definitive conclusions. Ultimately, the essay suggests that JCO’s writing stimulates inquiry and self-reflection, positioning art as a process of response rather than a vehicle for asserting categorical truths—including those of feminism.
