The Final Girl Without The Slasher: Final Girls, Gender, And Community In Psych, Cassidy Crosby

All Graduate Reports and Creative Projects, Fall 2023 to Present

This thesis focuses on the “Final Girl” trope, a hallmark of slasher films of the 1970s and 1980s, as it appears in detective procedural television show Psych to analyze what changes in the trope’s usage says about broader changes in American culture. I engage with two key episodes, “Scary Sherry: Bianca’s Toast” and “Tuesday the 17^th,” which contain the program’s most direct engagements with the Final Girl trope. Ultimately, I conclude that Psych rejects the hyperindividualism embedded in the Final Girl and some of the trope’s more binary gender norms, while also failing to interrogate other aspects of …

[M]Otherhood: Navigating Work-Family Constraints And Strategies In Pink-Collar Jobs, Madison Brunell

All Graduate Theses and Dissertations, Fall 2023 to Present

Working mothers continue to confront cultural norms and workplace practices that frame paid labor as incompatible with caregiving. In the workplace, these norms often result in motherhood bias and discrimination due to the incompatibility between norms of the ‘ideal worker’ and the ‘ideal mother’ (Acker 2006; Williams, Blair-Loy and Berdahl 2013). This tension is especially acute in pink-collar jobs, women-dominated occupations in service and care sectors, which are often mischaracterized as mother- friendly despite offering limited flexibility, low pay, and minimal structural support (Sartor, Lange, and Tröster 2023; Deming 2022; Ervin et al. 2022). While prior research has explored the …
