Long‐distance raw material transfers across Romania prior to the Last Glacial Maximum have previously been inferred from either visual and/or petrographic observations of East Carpathian sites. We investigated the potential to ‘fingerprint’ flint from archaeological sites at Mitoc‐Malu Galben and Bistricioara–Lut?rie III in Eastern Romania, using in situ high‐precision analyses of 28 major, minor and trace elements determined by laser ablation – inductively coupled plasma – mass spectrometry (LA–ICP–MS) in combination with multivariate statistical analysis. Our results suggest that geochemical analyses have the ability to distinguish between different geographical sources but are unable to positively associate flint artefacts from archaeological contexts to these geochemical groups. The mismatches of signatures between artefacts and geological materials, however, raise new questions and open unforeseen perspectives.  相似文献

This article is a study of West Papua's impact on the relationship between Australia and Indonesia. Its purpose is to enhance understanding of various diplomatic challenges emerging from West Papua, the origins of these challenges, and how they impact upon the relationship. This will be achieved through an analysis of a particular incident in 2006 in which 43 West Papuan refugees arrived in Australia. This led to a diplomatic storm between the Indonesian and Australian governments, and a highly charged public debate. Insights will be gleaned from the incident and its aftermath to broaden our understanding of West Papua's impact on the Australia-Indonesia relationship.  相似文献

The 1990s saw government initiatives restricting immigration in many countries, and a good deal of popular unease. Associated policies have targeted sex workers, as with the Policing and Crime Bill that is currently in its Third Reading in the House of Commons (UK). In the name of 'victims' of a trade organised by 'evil' traffickers, this Bill seeks further sanctions against all of those involved. This editorial asks whether initiatives during the current recession might not seem to succeed but for the wrong reasons. Immigrants are already leaving the UK in search of a living while local workers, who were promised safer working conditions in the wake of the murder of five women in Ipswich (2006), will be punished more and more. With its apparently humanitarian efforts to 'stop the traffic', the UK government will turn out to have replaced our 'slaves' from abroad with home-grown substitutes, and effectively solidified and further excluded an underclass. This situation suggests striking parallels with the panic over white slavery during the last comparable period of globalisation culminating in the First World War.  相似文献

This paper connects philosophical debate concerning the metaphysics and epistemology of counterfactuals to the methodological concerns of historical geography. It argues that counterfactual claims are implied by a wide range of common epistemic judgements, specifically those regarding evidential support and explanatory connection. In addition it argues against those who have sought to restrict the use of counterfactuals to, in particular, rational action, or systems that are inherently chancy. Rather it argues in favour of an expanded role for counterfactual method in history and geography, in the forms of imaginary experiments and the questioning of ‘what might have been’.  相似文献

Falling trees commonly turbate soils in primary forest, creating characteristic edaphic patterns related to pit and mound topography. Vernal ponds with associated mounds were observed in mineral soils on a treeless plain in subalpine Tasmania, Australia. The hypothesis that paired ponds and mounds on the plain originated as pit and mound features in forests that were later destroyed by fire was tested by comparing the soils and landforms caused by recent tree falls in adjacent forest with those on the plain. The soil characteristics, orientations, and dimensions of the ponds and mounds were consistent with a tree fall origin, although rare secondary ponds on the tops of mounds may derive from the burrowing activities of the medium‐sized marsupial, Vombatus ursinus (common wombat). The characteristics of pond and mound soils suggested that most were hundreds to thousands of years old, with the ponds persisting because of differences in deflation, deposition, and organic matter formation between themselves and adjacent persistently dry land.  相似文献

Investigators have long recognised the effects of microbial activity on archaeological bone. These investigators, however, have focused on single or groups of microbes rather than on complex microbial aggregates such as biofilms, a focus that has affected our understanding of archaeological bone biodeterioration. In this paper, we report on the investigation of a biofilm in archaeological human bone from the site of Tell Leilan, Syria (2900–1900 BCE). Scanning electron microscopy indicated that the biofilm is characterised by single cells and microcolonies of bacteria and fungi, as well as calcite crystals that were all embedded within extracellular polymeric substances. Using culture techniques and DNA sequencing, we isolated and identified several microbes from the biofilm including Amycolatopsis sp., Penicillium chrysogenum, Aspergillus sp., Chaetomium sp., and Cladosporium sp. Having characterised the Leilan biofilm, we are now closer to understanding the complex process of bone biodeterioration in archaeological bone collections.  相似文献
