The University of Queensland's School of Political Science and International Studies organised a round table in Canberra on 27 June 2001 that brought together a select group of government policy-makers and academic specialists to discuss the issue of ballistic missile defence (BMD). The round table provided useful insights into Australian thinking on the issue. This report seeks to summarise the essence of those discussions in order to contribute to the broader national debate.  相似文献

This article argues that, over the decades, Australians have held three different, coherent, long-lived ‘visions’ of nuclear weapons and strategy. Those visions—which we have labelled Menzian, Gortonian and disarmer—compete on four grounds: the role that nuclear weapons play in international order; the doctrine of deterrence; the importance of arms control; and the relevance of nuclear weapons to Australia's specific needs. We believe this ‘textured’ framework provides a richer, more satisfying, and more accurate understanding of Australian nuclear identity, both past and present, than previous scholarship has yielded. Moreover, the competition between the three visions might not be at an end. Changes in international norms, in proliferation rates, in regional strategic dynamics, or even in the deterrence doctrines of the major powers could easily reawaken some old, enduring debates. Australian nuclear identity faces an uncertain future.  相似文献

The cooperation of China and India in replacing chemicals that damage the stratospheric ozone layer is critical to the success of the world's first environmental agreement, the Montreal Protocol. China's leaders accepted the agreement more readily than did their Indian counterparts. These divergent responses are attributed to the nature of the policy issue in question, the impact of regime type upon state leaders' environmental policies, and dissimilar linkages between international and domestic actors and forces.  相似文献

Editorial     
Similarities in late Middle Cambrian trilobite, inarticulate brachiopod and molluscan faunas are apparent between Bornholm (Denmark) and New Zealand. Tuarangia gravgaerdensis sp. nov. is described from the late Middle Cambrian Andrarum Limestone of Bornholm, Denmark. The Andrarum Limestone is stratigraphically correlated with the Tasman Formation, New Zealand, from where the genus Tuarangia was first described. A single specimen, referred to Tuarangia, has been found in an erratic boulder from NW Poland. The boulder is estimated to be of early Late Cambrian age. The initial taxonomic assignment of Tuarangia to the Bivalvia, Subclass Pteriomorphia, is upheld. The distance between Bornholm and New Zealand, the position at opposite hemispheres, and the palaeogeography in general clearly indicate isocommunities with restricted possibility of exchange of the gene pool at species level.  相似文献
