A cobertura jornalística de fronteiri？os e favelados : narrativas securitárias e imuniza？？o contra a diferen？a

the article discusses the immunization perspective against difference produced by brazilian journalistic coverage about events occurred in peripheries of brazilian international borders (fronteiras) and in its metropolitan areas (favelas). the methodological option that sociossemiotics brings allows the analysis of coverage of events conducted by local media, by a corpus created from editions of 2006 and 2007 of a frontier daily newspaper, in contrast with the analysis of two weekly national newspapers of the same period. the mainly objective was to understand the specificity that local level concedes to events alreadystandardized by national media. results point to the consistency of the hypothesis that journalistic agency keeps news about peripheries in an ambiguous discursive condition and that responds by its framework as fire alarms, converting them into territorial patrimony of national state.
