A Right-of-Centre Triumph: The 2004 Australian Half-Senate Election

The Australian Senate is a significant part of the Australian parliamentary system and the electoral contest for the Senate results in representational outcomes that will influence the way the Senate will perform. This paper argues that the 2004 half-Senate election result was significant because it resulted in the Liberal–National Coalition obtaining a majority in the upper house. It accounts for this outcome by examining the contest by way of inter- and intra-party bloc contests. It finds that a particularly strong Right-of-Centre performance in Queensland, to which voters voting for Ms Pauline Hanson made a major contribution, delivered the Senate majority to the Howard government. The significance of the result also lies in the way it confounded previously held views that the combination of proportional representation used for the Senate with the need to elect six senators from each State would make it unlikely for either Labor or the Liberal and National Parties to ever win an upper house majority in the future.     

Changing the Rules to Change the House: Electoral Reform and the 2006 Electoral Contest for the Victorian Legislative Council

On 25 November, 2006, Victorians participated in a general State election in which a new electoral system was being used for the Legislative Council. The electoral reform was part of an overall reform of the upper house undertaken by the Bracks Labor government. This article examines the electoral reform of the Victorian Legislative Council and the politics associated with this major change. It argues that this reform was the product of a Labor commitment to reform Australia's State upper houses that had already been implemented in three other States. It also reviews the outcome of the 2006 election to assess the extent to which the outcome matched the expectation of advocates of reform.     

The Trouble-maker's Ballot Box? A Note on the Evolving Role of the Australian Federal By-election

By-elections have the capacity to result in political outcomes beyond simply filling casual vacancies when they arise. This paper examines data pertaining to federal by-elections in Australia since 1949 in order to ascertain the extent to which there have been changes in these special electoral contests. This paper argues that, although the rate of representational change has not been great in federal by-elections, there has nonetheless been an evolving notion that these contests give non-major party candidates greater scope to influence the political debate. However, it is also argued that this enhanced scope for non-major party 'trouble-making' has been the product of an emerging feature in Australian by-elections-specifically, the increasing incidence of strategic absenteeism by the major political parties.     

Parties,Participation and Outcomes: The 2008 Victorian Local Government Elections

In November 2008, voters in Victoria participated in local government elections under a system that has been subject to significant reform since the 1980s. This paper seeks to discern trends from the outcomes and identify significant structural features of the reformed system. With regards to outcomes, the paper highlights the high success rate amongst incumbent councillors and the strong sense of successful candidates being independent of political parties. The paper argues that these outcomes have been particularly influenced by the proliferation of electoral districts with relatively small voting populations or by the use of multimember electoral systems in larger districts. The variety of systems used underpins a localised and ‘clientelist’ politics that militates against the dominance of political parties over the contest. The paper also draws attention to the comparatively low rate of voter participation in an election in which compulsory voting applies. It argues that voter absenteeism was particularly noticeable in municipalities with large numbers of residents renting properties and might be explained as a form of ‘renters’ illusion’ impacting on voting behaviour.     

SEISMIC DESIGN AND ANALYSIS OF A KNEE BRACED FRAME BUILDING

A five-storey steel frame incorporating dissipative knee elements is designed using the Eurocode 8 pushover analysis method. The non-linear analysis makes use of a novel knee element model capable of accurately simulating the bending and shear behaviour observed in full-scale tests. The performance of the structure is assessed using non-linear time-history analysis. This shows that the knee elements can be designed to yield under small earthquakes or early in a strong one (maximising their energy dissipation) while still being able to withstand a large event without collapse. Knee elements thus have the potential to give excellent seismic performance in steel framed structures. The time history analysis results are compared to those obtained with the three different pushover analysis methods (Eurocode 8, FEMA 356 and ATC 40). The FEMA 356 method, which includes a more accurate representation of the structure's significant post-yield stiffness, gave the closest agreement with the time history analyses, while the Eurocode 8 method gave rather conservative results and the ATC 40 method appears non-conservative for this type of structure.     

Ancient-DNA reveals an Asian type of Mycobacterium leprae in medieval Scandinavia

Leprosy is a chronic infection of the skin and peripheral nerves caused by the pathogen Mycobacterium leprae. Its impact on human populations and societies of the past as well as its phylogeographic patterns around the world – at least in modern times – has been well documented. This slow growing bacterium has been shown to exist in distinct ‘SNP types’ that occur in relatively defined parts of the globe. The routes that the disease followed in the past are, however, still uncertain. This study of ancient-DNA typing of archaeological human remains from Sweden dated to early Medieval times provides genetic evidence that a transmission of M. leprae ‘SNP subtype’ 2G – found mainly in Asia – took or had already taken place at that time from the Middle East to Scandinavia. This finding is unique in the history of leprosy in Europe. All human specimens from this continent – both modern and ancient – that have been tested to date showed that the one responsible for the infection strains of M. leprae belong to ‘SNP type’ 3, whereas our results show that there were some European populations that were hosts to bacteria representing ‘SNP type’ 2 of the species as well.
