This paper compares two contrasting Australian case studies in the archaeology of Indigenous-European interaction: one mission-like in its intent, the Aboriginal Settlement for Tasmanian Aborigines at Wybalenna on Flinders Island in the Bass Strait (1833–47), the other the Lutheran mission at Lake Killalpaninna (1867–1928) investigated by the Central Australia Archaeology Project (CAAP). Each of the two case studies adopted different strategies of investigation. Wybalenna was a small excavation while Killalpaninna was an extensive surface survey. Both studies reveal diversity in the range of responses to a missionizing program, providing evidence of agency in the formation of the archaeological record. They demonstrate the value of the material evidence and the significance of archaeology in contributing to a more sensitive understanding of the interaction process by providing an alternative to textual sources.  相似文献

Until now, the oldest known human hair was from a 9000-year-old South American mummy. Here we report fossil hairs of probable human origin that exceed that age by about 200,000 years. The hairs have been discovered in a brown hyaena (Parahyaena brunnea) coprolite from Gladysvale cave in South Africa. The coprolite is part of a hyaena latrine preserved in calcified cave sediment dated between 195,000 and 257,000 years ago. This find supports the hypothesis that hyaenas accumulated some of the early hominin remains found in cave sites, and provides a new source of information on Pleistocene mammals in the Sterkfontein Valley.  相似文献

Soil multi-element analysis is now a routine technique employed to help answer questions about space use and function in and around archaeological sites. The pattern of enhancement of certain elements, including P, Pb, Ca, Zn, and Cu, has been shown by numerous studies to correlate closely with the archaeological and historical record. Interpretation of these soil signatures, however, has generally been more problematic. One approach to the problem has been the use of ethnographic or “known” sites to guide interpretation, but how confidently can results from one site be extrapolated to another? This study of abandoned farms tests the site specificity of soil multi-element signatures of past space use through the use of discriminant models. Data analysis suggests that one to one comparisons of similar sites are much less accurate (38% accuracy) than comparisons based on a wider range of sites (59.3% accuracy), even when the latter have contrasting geology. The results highlight the importance of individual anthropogenic practices during occupation and abandonment in the development of diagnostic soil geochemical signatures.  相似文献

文化定式是指在跨文化交际过程中,人们将具有相同特征的一群人或者任何民族、种族塑造成一定的形象。不同的社会文化背景和历史条件下,人们对事物的认识会发生变化,有时认识与真实情况完全相悖。苏联不同时期社会对外部世界的认识不一,根本原因在于官方宣传的引导,次要原因是社会传统和文化传承。既有的社会文化定式将长期影响人们对事物的认识。  相似文献

A key area in the analysis of urban structural evolution is identifying discontinuities. Effective analysis could improve long‐term forecasting and provide a better understanding of how to steer an urban system toward a desirable future state. We use a simple aggregate retail model to demonstrate an algorithm for identifying discontinuities in model parameter space. Explorations of retailing in both Greater London and South Yorkshire in the United Kingdom illustrate how understanding a system's potential for discontinuity can provide insights for both policy makers and retail businesses. The Harris and Wilson model, described in the section so‐named, is used as a simple archetype to illustrate the new framework. This model can be developed in a straightforward way to incorporate further refinement. In “ Executing the model and visualizing the results ,” we describe a single model run and in “ Investigating discontinuities ,” we explain our framework for detecting and analyzing discontinuities. “ Identifying discontinuities in the London retail system ” shows the results of applying this methodology to the Greater London retail system, and in “ Practical applications ,” we explore the policy applications for this technique as related to the decline of town centers in the South Yorkshire retail system. Some concluding comments are offered in “ Conclusions .”  相似文献

This paper considers the transition from Howiesons Poort to post-Howiesons Poort technologies at the rock shelter site of Klein Kliphuis, South Africa. The transition at this site is shown to be gradual, with incremental changes in material selection and in the size and shapes of flakes and cores. Implements which appear to blend characteristics of those distinctive of the earlier and later industries appear briefly at the mid-point of the transition. The results suggest that there is unlikely to have been an occupational hiatus between the Howiesons Poort and post-Howiesons Poort. Explanations for the Howiesons Poort phrased in terms of population expansion and contraction are also difficult to support. Technological changes at this time may relate to environmental variation, though the limited nature of terrestrial archives documenting changes in resource productivity necessitate that any such suggestion be made with caution.  相似文献

Since 2005, a burgeoning wave of Chinese investments has set off a new ‘minerals boom’ in the Australian iron ore and coal mining sectors. While normally a welcome development, the state-owned and strategic nature of the investors has raised concerns in Australia about how these should be regulated. As a result, in February 2008 the Australian government declared an intention to more closely screen foreign direct investment (FDI) from state-owned sources, which both supporters and detractors alike have claimed is evidence of ‘resource nationalism’ in Australia's approach towards its trade and investment relationships with China. This article challenges this understanding through an examination of the characteristics of Chinese mining FDI, the dilemmas these present to the Australian government, and the relatively restrained nature of its response. Through this, Australia's FDI policy is explained as a defensive move against the potential for strategic behaviour by Chinese investors resulting from their state ownership, rather than any national program to subject minerals trade and investment to political control. On this basis, the article argues that Australian government policy instead evidences a ‘resource liberalism’ approach, which intends to ensure that the governance of Australia's minerals trade and investment with China remain market-based processes.  相似文献
