Zoos and aquariums are responding to the worldwide biodiversity crisis through major conservation initiatives like captive breeding for assurance populations and reintroduction programs. These institutions also fundraise, offer education programs, and provide critical research on biodiversity. Through a case study inside three accredited Canadian zoos, this paper illustrates that zoos and their staff members are being incorporated into many official species‐at‐risk recovery efforts on provincial, federal, and international levels. Specifically, the zoos studied are involved in every stage of the recovery process, from providing valuable research and habitat analyses, to captive breeding animals for reintroduction, to writing recovery strategies and creating recovery policy for multiple jurisdictional levels. Zoo staff indicate that zoos are uniquely suited to conservation because zoos have space, expertise, apolitical status, and the ability to connect with the public. Overall, the paper suggests that zoos can significantly contribute to species‐at‐risk protection and recovery in Canada and beyond. 相似文献

Badgers represent one of the most controversial and hotly debated environmental issues in modern Britain. This paper advances the study of the Advocacy Coalition Framework (ACF) by examining the limited extent to which extensive scientific research over a 15‐year period changed the basic composition and argumentation of different advocacy coalitions in a highly adversarial setting. Based on coding of the media coverage over the period 1986–2013, this paper analyzes the composition of the advocacy coalitions, their stability over time, and the limited extent to which learning took place in response to scientific disputes. It also highlights how coalitions between actors with similar policy beliefs did not form, highlighting the importance of the ACF and other policy processes to consider dynamics that go beyond the individual subsystem under investigation. 相似文献

The era of public management change is said to challenge traditional "command and control" modes of governance, encouraging a move toward either more informal forms of (co-) governance or market-type incentives and competition. Regardless of whether these claims are made by reform advocates or by more sceptical observers within the wider governance debate, less attention has been paid by either side on the mechanisms that are supposed to facilitate the spread of new forms of control. This article seeks to advance this state of affairs in two ways. First, it utilizes the notion of institutional isomorphism to explore the nature of change of modes of control. In particular, it assesses the mechanisms for change, whether control mechanisms are changing due to coercive, mimetic, or professional mechanisms. Second, it explores the impact of these mechanisms in the federal context of Germany in two policy domains, prison and local government supervision (in the field of building administration). Finally, this article suggests that cultural theory offers considerable insights for the study of institutional isomorphism by emphasizing conflicting worldviews and the diversity of related policy ideas as driving forces of change in modes of governance. 相似文献
