Estudos culturais latino-americanos: configurações de um sintagma by Alfredo Cordiviola

“…Between common interests, points of convergence, contrasts and antagonisms, the tensions that chara cterize the two parts of a phrase such as „Latin American Cultural Studies‟ served to rethink the field of study, the practices and knowledges and also the ways in which ideas circulate and academic policies are set in a context marked by the diversity of enunciative locus and by the reworking of epistemic categories.…”
