This unique volume is an outstanding tribute to Al Kahn one of the most influential researchers on children welfare in the 20th century and an impressive collection of 23 chapters written by leading researchers in the field. The book provides an exceptional opportunity to 'experience' the history of the last 50 years of child welfare as well as its current status and future. The book chapters take us through the movement, from a deficit-oriented policy to a developmental model, from a targeted and selective strategy to a universal approach, from child welfare to child well being. Chapters contributed by world renowned experts from 6 countries and 4 continents, are organized in 5 clusters. The first one, which includes Al Kahn last written contribution to the field, looks at how children and families have changed over time as did the research on their well being. The next cluster of chapters focuses specifically on the traditional child welfare system. Following are several chapters on different theoretical perspectives in children welfare and well being. The fourth cluster of chapters focus on economic support for child and family well-being. Finally, the last cluster of chapters advance the agenda moving toward discussion of child well being. This book is a must for anyone interested in children welfare and well being in research, practice, advocacy and policy making arenas.
