This book, first published in 1986, examines the connections between basic research in the social sciences, and political and social action to improve the situations of children, youth, and families. In the 1950s and 1960s, following the many effective applications of their work during World War II, there was a vigorous interplay as well as division between social scientists and those engaged in programme development. Adducing the model of the physical sciences, Robert N. Rapoport and his collaborators argue that this divergence contributes to inhibition of action initiatives, on the one hand, and stagnation in the quest for knowledge, on the other. Dr Rapoport raises ten key questions about the appropriate relationship between research and action, and these issues are discussed in the fields of education, youth employment and unemployment, juvenile justice, child health, community mental health, social services, and family research by authors who have had extensive and authoritative involvement in these areas.
