We end the week with a closer look at the career and guiding beliefs of the University of Washington prevention scientist Professor David Hawkins who on Wednesday counseled Birmingham UK on the public health approaches that might be adopted by its 50,000 children’s services workforce. He was in between visits to Northern Ireland to give advice on drug misuse and to the Republic of Ireland to consult with philanthropy on how best to promote communities that care.

After Steve Aos’s insights into cost-benefit analysis, a second US expert, Professor David Hawkins from the University of Washington’s Social Development Research Group gives keynote advice and encouragement to the Birmingham workforce leading the city’s $2.6bn Brighter Futures prevention initiative.
