Policy network analysis has been criticized for failing to adopt a sufficiently dynamic approach to the study of policy-making processes. There have been, however, a number of studies illustrating how policy networks change, recognizing that they are not static entities but respond to changes in the policy environment. This article applies policy network analysis to the negotiation of plans to implement the 1994 EC Packaging and Packaging Waste Directive in the UK and provides a further contribution to the literature on the formation and transformation of policy networks. The analysis reveals significant changes in the structure and operation of the policy network during the period studied. The reasons for such changes confirm those put forward by other policy network analysts, such as the power of the actors involved and conflicts between them. Other reasons include the role of the government and the tight schedule laid out by the directive.  相似文献

Infants aged younger than 12 months have the highest homicide victimization rate of any single age group in England and Wales. In addition, there are good grounds for believing that the official homicide statistics for this particular age group are an underestimate and subject to distortion. At the same time there is evidence mounting in the United Kingdom that some parents have been incorrectly convicted of infanticide. This article first explores all recorded cases of infanticide in England and Wales for the period 1995-2002 (298 cases in total). Characteristics of the offenders, victims, offense, and court outcomes are examined. The second part of the article takes a critical gaze at the complexities involved in distinguishing infanticide from sudden infant death syndrome (SIDS) and other sudden unexplained deaths in infancy (SUDI). The article ends by considering in what ways infant deaths might be more effectively investigated.  相似文献
