Power is a key concept within social and political theory. Without being able to give justice to such a complex concept and its history, we want to first point to some of its most salient roots to then highlight aspects of the concept of power that have been developed in different theoretical traditions and are relevant for our analysis. We look more deeply into three aspects of power: how decisions in the two projects were shaped by structural arrangements; which "mechanisms' participants used to align their work and different positions, finding instances of "power to" but also of influence, trust and loyalty in how choices were introduced and selected. We also discuss issues of power/knowledge, examining in particular how topics were constructed through "discourse" and exploring instances of "normalising practices".
