Today and tomorrow there is a very interesting workshop at IESA, in Cordoba, Spain, one of the first institutes in Europe to dedicate itself to research on participatory institutions. There has been no lack of interest in the study of participation, and the conference takes stock of the last ten years or so of research in the area. Turns out this area of research is very plural, with presentations from topics as varied as Experimental Design, ethnography, survey, and a variety of comparative approaches in between. The program is online, as will be some of the presentations.
