The evaluation of electoral redistributions: the case of Western Australia*

Electoral boundaries may be delimited by electoral commissioners who are explicitly non-partisan but the consequences of their decisions are generally highly partisan. An evaluation of the State redistribution in Western Australia reveals that the Liberal Party was given a significant initial advantage for the 1983 State Election. Indicators used in the evaluation procedure include political party competition, shape, the integrity of political units, predictors of voting behaviour, as well as the re-aggregation of the 1983 election results by the pre-redistribution boundaries.     

The origin of overpressure in 'old' sedimentary basins: an example from the Cooper Basin, Australia

Overpressure in ‘old’ sedimentary basins that have not undergone rapid, recent sedimentation cannot be easily explained using traditional burial‐driven mechanisms. The last significant burial event in the Cooper Basin, Australia, was the Late Cretaceous deposition of the Winton Formation (98.5–90 Ma). Maximum temperature in the basin was attained during the Late Cretaceous, with cooling beginning prior to 75 Ma. Hence, overpressure related to rapid burial or palaeomaximum temperatures (e.g. hydrocarbon generation) must have developed prior to 75 Ma. Retaining overpressure for 75 Ma in ‘old’ basins such as the Cooper Basin requires extremely low seal permeabilities. An alternative explanation is that overpressure in the Cooper Basin has been generated because of an increase in mean stress associated with an increase in horizontal compressive stress since Late Cretaceous times. Structural observations and contemporary stress data indicate that there has been an increase in mean stress of approximately 50 MPa between Late Cretaceous times to that presently measured at 3780 m. The largest measured overpressure in the Cooper Basin is 14.5 MPa at 3780 m in the Kirby 1 well. Hence, disequilibrium compaction driven by increasing mean stress can explain the magnitude of the observed overpressure in the Cooper Basin. Increases in mean stress (tectonic loading) may be a feasible mechanism for overpressure generation in other ‘old’ basins that have undergone a recent increase in horizontal stress (e.g. Anadarko Basin).     

The regional consequences of a dualistic industrial structure: the case of Australia

This article is a preliminary attempt to consider the spatial consequences of business organisation segmentation in the Australian economy. The first section outlines a framework that can be employed in an analysis of business organisation segmentation. The second section applies this framework in the context of the Australian economy. This section is in three parts. First, it is shown that conventional sectoral data can be used to approximate business organisation segmentation. Second, the labour market consequences of this empirical exercise are documented. Finally, the spatial consequences of the exercise are shown by way of a series of maps.     

The Italian public sphere: a case of dramatized polarization

This contribution is organized along two main interpretive lines. First: the Italian public sphere is very polarized because of well-established historical attitudes, a crowded media market and new technologies that push towards segmentation of the audience. The arrival of Berlusconi has only reinforced the already existing polarization that goes well beyond the borders of partisanship involving the content of news, the structure and professionalism of news outlets and also the recipients that divide themselves along the lines of political attitudes. The second characteristic feature of the Italian public sphere involves the tendency towards dramatization, which is also produced by the sudden commercialization of the entire mass media system that started in 1980. This article's thesis is supported by examples of dramatization and extreme political discourse. The consequences that derive from this situation are discussed in the conclusion.     

Policy change and network termination: The role of farm groups in agricultural policy making in Australia

As the National Farmers' Federation (NFF) celebrated its 25th anniversary in 2004, it is timely to reflect on the role of farm groups in agricultural policy making in Australia and revisit the policy changes of the 1970s which provided a major impetus for the NFF's formation. Agricultural policy is often presented as the classic case of policy developed by tight policy communities characterised by stability, shared ideology and limited membership. There has been much debate in the literature about the value of the concept of policy communities in explaining policy development processes and policy change. This article suggests that the combination of ideological and institutional change, particularly in the presence of looser policy networks, can disrupt policy making and lead to network termination resulting in policy change.     

Ordovician biostratigraphy of the Canning Basin,Western Australia

Six biostratigraphically distinct faunas based largely on trilobites and graptolites are defined from the Lower to Middle Ordovician limestone, sandstone and shale sequence of the Canning Basin. They range in age from the Tremadoc (fauna 1), through the Arenig (faunas 2, 3) to the Llanvirn (faunas 4–6).     

Approaching regimes: Australia,Canada, and environmental policy

Study of regimes has become an increasingly important feature of empirical studies of the bases of world order. Much research has focused on the dynamics and internal working of regimes in a number of different policy areas. The determinants of the approaches of states to regimes, however, have been relatively neglected. Using findings from Australian and Canadian approaches to the international environmental regime, this paper explores seven sets of factors that are argued to be crucial to understanding responses: the ecological‐economic milieu of states, the developmental attributes of a regime, bureaucratic politics within national governments, the influence of governmental structures such as federalism, interest group activity, the foreign policy orientations of states, and the regime capabilities of states. Regimes are an enduring feature of international society, but neglect of the complexity and variety of national approaches can lead to ineffectual policy recommendations.     

Ordovician acritarchs from the Canning Basin,Western Australia

A left mandibular toothplate of a chimaeroid fish collected from the Toolebuc Formation (Early Cretaceous, Albian), central Queensland is described. Comparisons with other chimaeroid genera show the toothplate to be sufficiently distinct to warrant the erection of a new genus. Ptyktoptychion tayyo gen. et sp. nov. is distinguished by the size and shape of its three tritors, the form of the symphysial facet and the overall shape of the toothplate.     

The Herbert River,Queensland, Tropical Australia: Community Perception and River Management

There is a widespread perception amongst the community of Ingham and surrounding areas that the Herbert River in tropical Queensland has aggraded since the time of European settlement. Yet this perception is not supported by such evidence as historical accounts of the river and river trade, changes at the Ingham gauging station since 1940 and comparison of channel cross-sections surveyed since 1968. No reason has been identified for this divergence, but experience elsewhere teaches us that ignoring local perception is likely to result in an incomplete understanding of environmental issues. Unless the challenge of reconciling popular perception and deductive interpretation of the evidence is met, the potential for conflict will remain. Community proposals for strategies will struggle for support from the ‘rationalists’ and the community will oppose ‘rational’ strategies if they are not seen to be addressing the ‘real’ problems.     

Post-war smoking policy in the UK and the redefinition of public health

Current analyses of UK smoking policy within two frameworks--the 'heroes and villains' view of journalist accounts and a political science emphasis on rival 'producer' and 'issue' networks in policy making. It is often assumed that the US experience provides a universal historical model. This paper sees smoking policy in the UK as a case study in the relationship between 'scientific fact creation' and policy, which has also been emblematic of wider changes in public health ideology. The issue of smoking and lung cancer symbolized the post-war shift from infectious to chronic disease and the rise of a new 'lifestyle'-oriented public health. In the 1980s passive smoking brought a revival of environmentalism; in the 1990s the rediscovered concept of addiction symbolized developments in public health in which curative and preventive initiatives were entwined. Despite the rise of a militant 'healthism' within both anti-smoking and public health since the 1970s, British policy retained a dual focus, an emphasis on risk reduction as well as risk elimination in which policy networks were entwined rather than distinct. Some public health scientists worked in policy milieux, notably the expert committee, which crossed this apparent divide and which linked with industry. Connections between government and industry changed as public health 'treatment' brought the pharmaceutical industry into the picture.

Federal intellectual property policy and the history of technology: The case of NASA patents

This essay explores two closely entwined issues in recent history of federal R&D policy: (a) the disposition of the US government intellectual property (IP), and (b) how to best assess the effectiveness of federal patenting and licensing policies. It does so by examining two decades of patenting policy and practice at the National Aeronautics and Space Administration (NASA). The essay concludes with observations on the limits of our current approach to collecting data on the disposition of federal IP, and an alternative framework for examining the role of IP in the history of modern technology.     

Rethinking suburban development in Australia: a Melbourne case study

This article considers suburban development in Australia through the lens of its second largest city, Melbourne. Contemporary urban policies have focussed on the low densities within Australia's capitals and tried to achieve sustainability through urban consolidation policies. The article argues that these policies are often based on a distorted understanding of the relationship between housing markets and labour markets in Australia's large metropolises. The analysis of suburban development in Melbourne shows that suburban development involves complex links between changes in housing and job location and that urban sustainability policy needs to include actions designed to change the distribution of employment as well as the location and density of housing. The article shows that the vast spread of the Melbourne population masks closely linked regional labour and housing markets.
