Social work scholars and students must increasingly be sensitive to the need for knowledge sharing between countries as well as to issues involved in obtaining and utilising international knowledge. Yet until now, no book has juxtaposed these two growing streams of emphasis. The authors establish three discrete varieties of research - supra-national, intra-national, and trans-national - and explore a wealth of issues and examples within each. The easy-to-follow format helps readers learn how to define and distinguish each kind of research, then provides examples of actual applications of all three.
