Talk about globalization is all around us. It is far rarer that suitable definitions of what globalization is, and accounts of the many ways in which global connections and interdependencies affect and shape us, are provided. This is precisely what this Research Handbook offers: sociological conceptualizations of what globalization entails; interdisciplinary approaches to its many dimensions; critical analyses of today’s complex interplays of the global, the local and the political; up-to-date empirical accounts of the effects of globalization on life courses in contemporary societies and cutting-edge discussions of the historical, methodological and ethical questions our global interconnections present for the social sciences. This Research Handbook takes stock of the state of the art in sociological research on globalization and the contributors outline future trajectories for this, one of the most pressing and challenging sociological themes of our time.
