I highly recommend this book which has several case-studies of complex change over time. Complexity theory fits the social sciences well because there is both stability and instability in the social patterns. Here we find good empirical examples. The author observes patterns over time using three main methods: a complex cluster analysis, the discerning of prime implicants from among the configuration’s characteristics, and Boolean truth-table analysis. The author thus reduces and simplifies the findings. The book makes extensive use of Qualitative Comparative Analysis (QCA) while extending this ‘mixed method’ to an intertemporal range. Wendy Olsen, Reader in Socio-Economic Research, The University of Manchester, UKThis book responds to two important currents influencing contemporary social science: critical realism and complexity science. It provides an account of a promising new analytic method, Dynamic Pattern Synthesis, and illustrates how one can use the method with examples including the analysis of health and social care. I look forward to the application of this innovative and powerful method to a wide range of policy-relevant topics.Nigel Gilbert, Professor of Sociology, University of Surrey, UK
