the significant events and surrounding circumstances of the pacification process have been the subject of much reasearch, debate and commentary within the city of rio, across brazil and internationally.

written in 2012, the O Efeito UPP na Percepção dos Moradores das Favelas (The Effect of the UPP in the Perception of Favela Residents) by Marcelo Baumann Burgos, Luiz Fernando Almeida Pereira, Mariana Cavalcanti, Mario Brum, and Mauro Amoroso analyzes the perceptions of residents of four favelas occupied by UPPs (Unidades de Polícia Pacificadora, or Pacifying Police Units),

The paper is particularly concerned with how UPPs impact residents' daily lives, their future projects, their relations to the so-called formal city, and their associational life. An analysis of the empirical data allows for an assessment of the dilemmas, limits and potentialities of the UPP program, and grounds a reflection on its reach in terms of assuring citizenship rights not only in favelas ostensibly occupied by UPPs, but in the metropolis at large.
