Dear Juan, Please find hereby attached in English and Spanish my paper "Three Challenges of Communication for Social Change" which I presented during the plenary session of Tuesday 10th of April. I'm not sure how is the procedure, in order to have all the papers and presentations uploaded at the Our Media website, which is why I'm sending this to the entire "logistics" list. Also, Jethro and I need to gather all the presentations from Stream 2. You might have some of them, since some people changed streams just before the conference. Regards, Alfonso
