I just saw this new book from Springer:
Neighbourhood Effects or Neighbourhood Based Problems?
A Policy Context
Editors: David Manley, Maarten van Ham, Nick Bailey, Ludi Simpson, Duncan Maclennan
ISBN: 978-94-007-6694-5 (Print) 978-94-007-6695-2 (Online)
Many of you may be able to get the whole thing free from Springerlink from your respective libraries. It has a lot of stuff on crime, but also health and lots on policy-relevant research, and most of the work is from the UK.
