'PbPPublic Policies are active in all areas of citizens’ daily lives and act on society as a whole. This dictionary does not merely define concepts such as ‘window of opportunity’, ‘governance’, ‘dependence on the path taken’ or ‘ibpolicy feedback’/ib. It shows how the main concepts of this field of study have been forged, modified and enriched to take account of the new players and instruments at work. By engaging in a dialogue, opening up to other disciplines and giving a strong place to the most current French-speaking and international research, it offers the intellectual tools needed to understand contemporary changes in public policy.’/PB
