This book advances the understanding and modelling of sensemaking and cultural processes as being crucial to the scientific study of contemporary complex societies. It outlines a dynamic, processual conception of culture and a general view of the role of cultural dynamics in policy-making, drawing three significant methodological implications: pluralism, performativity, and semiotic capital. It focuses on the theoretical and methodological aspects of the analysis of culture and its dynamics that could be applied to the developing of policymaking and, in general, to the understanding of social phenomena. It draws from the experience and data of a large-scale project, RECRIRE, funded by the H2020 program that mapped the symbolic universes across Europe after the economic crisis. It further develops the relationship between culture and policy-making discussed in two previous volumes in this series, and constitutes the ideal third and final element of this trilogy. The book is a useful tool for academics involved in studying cultural dynamics and for policy-oriented researchers and decision-makers attentive to the cultural dimensions of the design, implementation and reception of public policies.
