On Wednesday, February 14, 2018, Nikolas Cruz murdered seventeen individuals and injured seventeen others at Marjory Stoneman Douglas High School using an automatic rifle. Traumatized by this event and angered by the notion that this situation could have been avoided, survivor Emma Gonzalez would recite a speech, titled “We Call B.S.,” at a Ft. Lauderdale anti-gun rally, only three days after the incident, to speak on the issue of United States gun violence...
Submit to Sin: Contextualizing the Roman Empire in Augustine's Detailing of Sexuality in Confessions
Joseph Flores
Lone Star College - CyFair
Compiling historical studies of the Roman Empire’s concepts of family, sex, and social status, this work compares the greater society’s ideologies to Augustine’s retrospective narrative. By covering Augustine’s experiences with his abusive father, ascension in social status through Romanianus, conversion to Manichaeism, and strictly sexual relationship with his concubine, this essay engages with the social underpinnings of the Bishop’s articulation of the role of sex and Catholicism...

With an aim to understand the relationship between school dances and the sexualization of children, this research compares the “ideal selves” that present day American middle schoolers attempt to put forward at school dances versus the “actual selves” that they put forth. Erving Goffman’s work on the dramaturgical perspective and E. Tory Higgin’s self-discrepancy theory are utilized as tools to analyze middle schoolers expectations of dances in cringe comedies Pen15 and Big Mouth...
