This book provides a robust empirical and theoretical analysis of reciprocity and its implications for social work and social policy practices by discussing how ideas of reciprocity can be understood and applied to welfare policy and social care practices as well as how the act of reciprocity supports the well-being of citizens. Contributions from Finland, Austria, the UK, the USA and Canada illuminate the ways in which sociopolitical contexts influence the power relations between citizens, practitioners and the state, and the potential (or otherwise) for reciprocity to flourish. This will be essential reading for social care practitioners, researchers and educationalists as well as postgraduate students in social work and related social care and community-oriented professions and social policymakers. Maritta Törrönen is Professor of Social Work at University of Helsinki. Her main research interests concern theory of reciprocity, global welfare society, communities, power relationships, everyday life and well-being, which have points of reference with social work and social policy, childhood, child protection, family research and ethnic studies. Her recent research is linked to international social work and proactive social work. She is leading the project 'Reciprocal Encounters-Young People Leaving Care', funded by the European Union during 2016-2018.
