Presenting recent studies of non-profit organizations involved in poverty relief services in New York City in comparison with programmes in existence across the US, Street Practice provides a front-line, ground-level perspective on innovative research practices designed to solve community problems. It explores the manner in which organizations bridge the gap between research and policy advocacy, with an account of the ways in which research contributes to alleviating or solving a community problem, as well as details on successes and failures of advocacy work, problems and limitations of their research, funding constraints and political resistance. As such, this book not only offers compelling examples of social change in action, but also serves to introduce models for research and policy advocacy that can be applied similarly in other urban areas. Adopting a case-based learning approach that enables readers to better understand the dynamic process of research and policy advocacy, this innovative book will appeal to those with interests in poverty, homelessness, policy advocacy, social work and social change.
