Three visions of the bomb: Australian thinking about nuclear weapons and strategy

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.     

Measuring the Effects of Consensus-building Processes with Methods of Intervention Research

In recent years, both environmental policy and research have emphasized the importance of involving the public in decision-making. This push for more participation is driven by considerable optimism about its ability to improve the quality of decisions and developments. There is, however, a lack of empirical research to support this assumption. The few studies that have attempted to measure the effect of public participation are of limited validity, as they were based on ex-post data mainly gained from expert assessments or document analysis. This paper reports on a recent study to measure and compare the effect of two consensus-building processes in a systematic and reliable way. This involved developing a new evaluation method based on the methodology of intervention research in environmental psychology. It was tested and applied in this study with two similarly designed consensus-building processes conducted in two neighbouring valleys of the Eastern Swiss Alps. These evaluation experiments showed that (a) the new evaluation method can measure and compare the effects of consensus-building processes in a differentiated and reliable way; and (b) consensus-building processes have systematic and partly statistically significant effects (at least in the short term) on several aspects of regional consensus. The initial results suggest that this new evaluation method is a promising way of obtaining reliable evidence about the societal effects of participatory processes.     

Dating the Domestic Ceramics and Pipe Smoking Related Artifacts from Casselden Place, Melbourne, Australia

This paper compares the dates of manufacture obtained for the domestic ceramic and pipe smoking related artifact assemblages from Casselden Place, Melbourne. It has previously been argued that ceramic items, because of their potentially long use-lives, may be deposited many years after their date of manufacture and purchase. This is in contrast to pipe smoking related items, which tend to have very short use-lives. However, the results presented here demonstrate that there is no significant evidence for a time lag between the date of manufacture of the ceramic items and their incorporation into the archaeological record at Casselden Place.     

Isotopic Determination of Seasonality in Diet and Death from Nubian Mummy Hair

Sections of human hair from naturally desiccated Sudanese Nubian mummies representing X-Group (AD 350-550) and Christian (AD 550-1300) periods in the Wadi Halfa area have been analysed for their isotope ratios. Because the carbon in hair represents food intake over the growth period of this tissue, analysis comparing segments taken next to the scalp with those further along the shaft can indicate diet just prior to death as well as any recent shift in food consumption. Modern populations in this area practise seasonal crop scheduling which involves the cultivation of C₃ plants (wheat, barley and most fruits and vegetables) in the winter and the hardier C₄ plants (sorghum and millet) in the summer. Shifting isotopic values along the length of hair strands of the ancient inhabitants of this area demonstrate that this practice has its roots at least as far back as the Initial Phase of Intensive Agriculture. The most common season of death appears to have been summer, the time of greatest climatic, nutritional and physiological stress for both ancient and modern inhabitants.     

Rediscovering Australian federalism by resurrecting old ideas

The federal organisation of government in Australia is one of the least understood aspects of the Australian political system. Despite the durability of federal structures, federal theory in Australia remains largely underdeveloped. Aside from a few scholars who have persistently analysed the federal process, federalism in Australia has received attention as an outmoded system with little scope for distinguishing the benefits to be gained from understanding how government is organised. But where Australian federal theory has languished, American federal theory has flourished. This paper borrows some of the major ideas which have influenced analyses of government functions in the American ‘ system and posits them against analyses of Commonwealth and State government functions in Australia.     

Generalizing Impact Computations for the Autoregressive Spatial Interaction Model

We extend the impact decomposition proposed by LeSage and Thomas-Agnan (2015) in the spatial interaction model to a more general framework, where the sets of origins and destinations can be different, and where the relevant attributes characterizing the origins do not coincide with those of the destinations. These extensions result in three flow data configurations which we study extensively: the square, the rectangular, and the noncartesian cases. We propose numerical simplifications to compute the impacts, avoiding the inversion of a large filter matrix. These simplifications considerably reduce computation time; they can also be useful for prediction. Furthermore, we define local measures for the intra, origin, destination and network effects. Interestingly, these local measures can be aggregated at different levels of analysis. Finally, we illustrate our methodology in a case study using remittance flows all over the world.
