Overdone overkill – the archaeological perspective on Tasmanian megafaunal extinctions

The reasons for megafaunal extinction in Australia have been hotly debated for over 30 years without any clear resolution. The proposed causes include human overkill, climate, anthropogenic induced habitat change or a combination of these. Most protagonists of the human overkill model suggest the impact was so swift, occurring within a few thousand years of human occupation of the continent, that archaeological evidence should be rare or non-existent. In Tasmania the presence of extinct megafauna has been known since the early twentieth century (74, 85 and 86) with earlier claims of human overlap being rejected because of poor chronology and equivocal stratigraphic associations. More recent archaeological research has not identified any megafauna from the earliest, exceptionally well-preserved late Pleistocene cultural sites. In 2008 however an argument for human induced megafaunal extinctions was proposed using the direct dates from a small sample of surface bone from two Tasmanian non-human caves and a museum sediment sample from an unknown location in a cave, since destroyed by quarrying (Turney et al., 2008). Turney et al. (2008) supplemented their data with published dates from other Tasmanian caves and open sites to argue for the survival of at least seven megafauna species from the last interglacial to the subsequent glacial stage.     

Rice or millets: early farming strategies in prehistoric central Thailand

Ancient seeds from archaeological sites can provide clues that are crucial for understanding and characterizing subsistence strategies. This in turn contributes to our understanding of, and explanations for, the relationship between socioeconomic systems and organization of craft production. This article will examine the relationship between rice and millets at three prehistoric sites from a regional copper-producing center in central Thailand to provide new insights into the subsistence strategy of these communities and to better understand the relationship between these crops and their introduction and use in Southeast Asia.     

Interest rates and the 2004 Australian Election

During the October 2004 Australian federal election campaign the expected or possible effect of the election outcome on interest rates was a key point of differentiation between the Australian Labor Party and the Liberal–National Party coalition. The purpose of this paper is twofold. First, we examine whether this effect was a significant factor in the election outcome, as measured by the percentage swing towards the coalition in each electorate. Second, we use standard methodology from financial economics to examine whether the election outcome had an effect on interest rates. Contrary to media coverage of the campaign, we find that the election result did have an effect on interest rates but that the possibility of interest rate changes was not a dominant factor in the election result.     

'Hard Charger' or 'Station Queen'? Policing and the Masculinist State

Gender dynamics are continually displayed in police departments. A prevailing masculinism favors an aggressive patrol style and emphasizes felony arrests. By contrast, the dominant reform model in policing, community policing, trumpets close and cooperative relations with citizens. Community policing is thus resisted by masculinist officers who would rather chase 'bad guys' than attend neighborhood meetings. The author illustrates these gendered dynamics with field data from observations of the Los Angeles Police Department, and suggests that masculinism in the state works not just to uphold patriarchy but to suppress efforts toward greater democracy.

Indeterminacy in-decisions – science, policy and politics in the BSE (Bovine Spongiform Encephalopathy) crisis

Increasingly, non-human geographies have unfastened nature from its foundational moorings. In a parallel development, the benefits of adhering to precautionary and participatory forms of decision-making have become common place in environmental geography and in government policy. And yet, on closer inspection, there is a danger in these latter approaches that old certainties regarding non-human natures remain unquestioned. The result can be a tendency to gravitate towards bureaucratic and technical solutions to, or closures on, what are, first and foremost, political and open-ended problems. This paper uses an empirical engagement with BSE-related scientific and policy practices, along with insights from non-human geographies, science studies and poststructuralism to suggest that such certainties and resolutions are misplaced.     

Ancient olive DNA in pits: preservation,amplification and sequence analysis

The olive tree (Olea europaea) was domesticated by vegetative propagation of selected wild individuals with superior fruit. Later, new cultivars were established repeatedly from feral trees or from crosses between wild, feral, and domesticated trees. Thus the genetic background of many contemporary domesticated lines is a mixture of ancient cultivars and local wild trees. Ancient DNA may illuminate the complicated process of olive domestication because such DNA sequences provide data about ancient genomes that existed closer to the domestication events. Well preserved DNA must be available for such studies, even though in the Mediterranean region, where olive cultivation took place, the climatic conditions are not favorable for DNA preservation. To select for well preserved pits we measured their proportions of lignin by IR spectroscopy, and correlated this with parameters of DNA quality such as template length in an olive-specific repeat array, and template quantity as determined by real-time PCR amplification. Archaeological pits that passed these tests did contain high quality ancient DNA. We present the first ancient olive DNA sequences and compare them to modern wild, feral and domesticated lines.
