This thesis comprises eight publications produced between 2000 and 2009 in addition to a critical review of that work. The review considers the contribution made by the author to the perspectives on policy making offered by the framework of policy transfer and its subsequent applications within global social policy and related sub disciplines. It develops to explore the author's use of critical policy sociology and methodological work in social policy, education and political science in order to enhance existing perspectives on policy transfer. In contrast to rational linear models of decision making, alternative recursive deliberate approaches are suggested throughout this work. The review also considers aspects of the author's work on integrated working or trans-professionalism in the public services. Those aspects of his work on policy theory which illuminate professional learning are critically assessed.
