La vía del abandono en los cuentos de Amparo Dávila

Description: Amparo Davila's writing style is characterized by circumventing the boundaries between the real and the fantastic and between the known and the unknown. The author creates a narrative that evokes horror in the reader by mixing the uncanny of the unknown with the reality of the world. This study proposes that the sinister in Davila's stories are created by abandonment. This abandonment is the peremptory element of Davilian narrative and can be seen and examined throughout the author's literary w… more

Your Blues Ain't Like Mine: Voices from the Other Side of the Color Line

Description: This dissertation examines intra-racial colorism in works by writers who began their careers during the Harlem Renaissance, but whose writings span almost a century. In these writings, colorism; which can be defined as a bias directed toward an individual that is based on skin tone, is portrayed an intra-racial practice that results from the internalization of racist ideals. The practice relies on a hierarchy that most often privileges those closest to the color line. However, these depictions … more
