In Culture and Imperialism, Said illustrates that we have no "autonomous cultural forms," but rather "impure" ones that are the products of historically "discrepant experiences." American culture has an interesting relationship with the history of imperialism. The Europeans that settled the U.S. imported slave labor to assist in the growth...
Recent studies have shown that queer, trans, and non-binary students alike are experiencing sexual assault at higher rates than their heterosexual, cisgender counterparts (Cantor et al. IV). While conversations surrounding university sexual assault education and prevention have increased in recent years, this disparity suggests that not enough is being done...
The Caribbean Plateau is an oceanic large igneous province (CLIP). A widely accepted model for LIP petrogenesis proposes that these large bodies of igneous rock are formed by decompression melting associated with upwelling mantle plume heads during the initiation of hotspot activity. According to this classical model, petrogenesis occurs over...
