Here are the slides for our last session. The sources are in the slides ... Jocelyne Bourgon and Beth Simone Noveck. Gordon Brown's argument is in his book (probably), but otherwise you could look at this Cisco white paper or the executive summary. The New York Times coverage of Brazil (Mayara Vivian) is here and here or download here and here. If you are interested in how to deal with the positive and negative effects of technology you should read this book by Kevin Kelly.
