This editorial reflects on the nature of public archaeology. It looks at the relationship archaeologists have with popular TV, focusing in particular on the new series American digger by Spike TV, and Diggers by National Geographic, and reflects on the relationship archaeologists have with amateurs using metal detectors to uncover treasures.  相似文献

A combination of stable carbon and nitrogen isotope analysis of collagen and radiogenic strontium isotope analysis of tooth enamel was used to investigate diet and mobility at the early Neolithic settlement of Nieder-Mörlen in Germany. The carbon and nitrogen ratios suggest a mixed terrestrial based diet that is consistent with data previously published for early Neolithic sites in Europe. The strontium isotope data indicate a high degree of human mobility with only one individual having an isotope ratio consistent with locally derived strontium. Unusually, a group of non-local juveniles with isotope ratios typical of upland regions is also present at the settlement but there are no adult burials with such values. Whilst transhumance is considered as an explanation, it would not explain why these non-local juveniles lived foreshortened lives and other possible mechanisms are therefore discussed.  相似文献

Abstract

The development of rule of law is touted as one of the most important considerations in Burma (Myanmar) today, yet its meaning is highly contested after fifty years of military rule. This paper will examine how the rule of law in Burma’s transitional political environment has been influenced by the legacies of military rule and the government’s development policies since 2011. A series of laws introduced by the Thein Sein government under the rubric of rule of law and good governance had a significant impact upon small hold farmers across the country. While some laws specifically related to farmers and their land, others encouraged private investment in the land used by farmers. The combined effect of these laws was to formalise the pattern of land grabbing that had developed under the previous government and to encourage land speculation. Moreover, they show how an expedited procedural rule of law incited conflict and further injustice. Any progress towards substantive justice and a more democratic rule of law must keep pace with improvements in the country’s limited administrative and judicial capacities. Whether, and how far, Burma can develop and move beyond a thin or procedural rule of law will be tested as the country experiences life under the NLD government.  相似文献

Pole, M., December, 2008. The record of Araucariaceae macrofossils in New Zealand. Alcheringa 32, 405–426. ISSN 0311-5518.

The Araucariaceae have a long record in New Zealand, extending back to the Jurassic at least, and Araucaria extends back to at least the Late Cretaceous. This paper reviews the macrofossil record of the family and presents new information based largely on the leaf cuticle record. Agathis, which is the only genus of the family currently growing in New Zealand, has no record before the Cenozoic. All specimens previously identified from pre-Cenozoic strata clearly belong to other taxa or do not show characteristic features of the genus. Araucariaceae macrofossils are virtually ubiquitous in the Cretaceous assemblages of New Zealand but are conspicuous by their absence or rarity in Palaeocene deposits. Their demise may be an expression of events at the Cretaceous–Palaeogene boundary.  相似文献

This paper examines the impact of animal manure on δ15N and δ13C values in a legume, Celtic Black broad bean (Vicia faba). In a field experiment, V. faba was cultivated in plots treated with farmyard manure and pure sheep manure. The results indicate that highly intensive manuring can increase δ15N values in beans, stems, leaves and pods. In comparison, manuring had a relatively small impact on δ13C values. In terms of palaeodietary reconstructions, the high δ15N values in very intensively manured beans (+3?‰) are equivalent to the trophic-level effect. Based on the experimental results, it is suggested that high δ15N values in archaeobotanical remains of V. faba may be attributable to small-scale cultivation with intensive manuring.  相似文献
