This two-day workshop held 13 - 14 June 2014 at the CENTRE FOR RESEARCH IN THE ARTS, SOCIAL SCIENCES AND HUMANITIES (CRASSH) in Cambridge, UK brought together leading actors of major capacity-building programmes with social scholars of science, technology and medicine in Africa. This conversation between the sciences, social sciences and humanities sought to enable critical examination of "capacity", and also invited the elaboration of new ways of sharing concerns, knowledge and analytical tools across disciplinary and institutional groups.
