Volume 1 "Policy Changes and Challenges" takes as its central theme the ongoing and challenging issues which child protection agencies have to address and the policy and practice initiatives that are developed to try and address these. The volume includes papers on: the relationship between the decline in the rate of 'unnatural' deaths and the growth of concern about child abuse in the USA between 1940 and 2005; mandatory reporting; the balance between providing urgent intervention and meeting chronic need; risk and the Public Law Outline in England; the nature and implications of 'child centred' policies; the impact of intimate partner and family violence; the intended and unintended consequences of high profile child abuse scandals; developing multi-disciplinary team work in a health setting; and the possibilities of technology-based innovations in prevention programmes.
