The need for experiments to study physical aspects of craft of the past is stated, as well as the necessity for them to have clear aims and to follow the established principles of scientific enquiry. These principles are discussed in this joint paper by ten maritime archaeologists and others, together with methods and some points of management critical to their application in this field.  相似文献

We review evidence from human biology—paleopathological and isotopic paleodietary studies on ancient Maya skeletons—to assess the validity of ecological models of the Classic Maya collapse, in which elevated disease and deteriorating diet are commonly assumed. To be upheld, the health arguments of ecological models require that the Maya disease burden (1) was greater than that for many other societies and (2) increased over the span of occupation. The dietary argument requires (1) consistent change in diet from Preclassic and Early Classic Periods to the Terminal Classic and (2) increasing social divergence in diet. A correlation between diet and disease is necessary to link these arguments. Neither pathology nor isotopic data consistently support these criteria. Instead, it appears that local environmental and political factors created diversity in both disease burden and diet. In view of the human biological data, we are skeptical of ecological models as generalized explanations for the abandonment of Classic Maya sites in the southern lowlands.  相似文献

Since 1979 the city council of Barcelona has sought to guide the city's destiny by a variety of methods, most powerfully by securing the 1992 Olympic Games candidacy, but also by means of two strategic planning exercises, begun in 1988 and 1992. These strategies are examined within their political and economic contexts in order to understand how they relate to changes in Spanish and Catalan politics, in global/local economic shifts and in thinking on city guidance. Significant differences in the three phases of city promotion are identified. It is concluded that strategic planning within the context of the intense spatial economic competition of the late 1990s may be even more difficult for Barcelona than was its drive up to 1992.  相似文献

In this paper I wish to contribute to an understanding of ‘Aboriginal resistance’ by a study of the politics of remote Aborigines' ‘employment’. I begin by highlighting some themes in recent discussions of the Community Development Employment Projects (cdep ) policy, before looking back at some features of the welfare and pastoral economy in the Central Australian hinterland, c. 1950 to c. 1975. My aim is twofold: to show some of the cultural continuities in the relationships between remote Aborigines and government; and to criticise constructively the notion of ‘Aboriginal resistance’, to advocate a structural and processual notion of ‘resistance’ and to move away from one based on the clear identification of actors.  相似文献

Madagascar's culture is a unique fusion of elements drawn from the western, northern, and eastern shores of the Indian Ocean, and its past has fascinated many scholars, yet systematic archaeological research is relatively recent on the island. The oldest traces of visitors are from the first century AD. Coastal settlements, with clear evidence of ties to the western Indian Ocean trading network, were established in several places over the next millennium. Important environmental changes of both plant and animal communities are documented over this period, including the extinctions of almost all large animal species. Urban life in Madagascar began with the establishment of the entrepôt of Mahilaka on the northwest coast of the island in the twelfth century. At about the same time, communities with ties to the trade network were established around the island's coasts. From the fourteenth to the sixteenth century, social hierarchies developed in several regions of the island. During the succeeding two centuries, Madagascar saw the development of state polities.  相似文献
