In the early seventh millennium BC an expansion of the Neolithic economy and sedentism took place in Asia Minor. This occurred nearly two millennia after the emergence of Neolithic societies in southern central Anatolia, which raises the question of how this expansion occurred, and why it came about at this particular moment. This paper considers various elements that might have played a role in this expansion episode, such as climate change, demography, and agricultural and social changes. 相似文献

RECOGNITION IN THE Castle Museum, Nottingham, of a ‘lost’ sword from a Viking-age warrior's grave excavated at Donnybrook, Co. Dublin, in 1879, has prompted a reassessment of the burial, which is discussed in relation to other Viking-age burials in the ‘Irish Sea province’. Detailed metallurgical analysis of the sword, undertaken during conservation, has provided important information about the techniques of its construction, and has demonstrated the potential of a variety of analytical approaches. 相似文献

This article demonstrates the relevance of future discounting behavior to studies of prehistoric subsistence strategies. The case study of Agave spp. bajada cultivation among the Classic Period, a.d. 1150–1450, Hohokam of southern Arizona illustrates how slight discounting of future rewards can significantly alter agriculture investment strategies. Despite a higher kcal/hour return than maize agriculture, agave cultivation lessened or ceased in several communities during a time in which intensification would be predicted due to inferred subsistence stress. We surmise the decade-long maturation of agave made it unattractive relative to more immediate return resources in any context that presented risks to land tenure. The cessation of agave cultivation can be understood on two levels of explanation. The long-term investments required by agave and tendency to discount future rewards are the ultimate causes. Political and social instability during the tumultuous Classic period, causing increased insecurity in land tenure, are the proximal causes. 相似文献

Regional policies across Europe aim at stimulating regional development in non-core regions through fostering entrepreneurship. However, the policies applied in non-core regions and the concepts of entrepreneurship these policies are based on differ. Therefore, the goal of this review is to identify different understandings of entrepreneurship and their role for regional development processes in European non-core regions. To this end, empirical studies investigating entrepreneurship in European non-core regions from 1999 to 2011 were analysed. The results of the analysis are presented along three drivers and outcomes of entrepreneurship identified inductively from the literature: innovation, social capital and institutional change. We made out seven different types of entrepreneurship in European non-core regions. These seven types of entrepreneurship comprise particular mechanisms through which they stimulate regional development. Further research should study the interplay between these different mechanisms of regional development in non-core regions which may induce a more territorial approach to understand entrepreneurship in non-core regions across Europe. 相似文献

As a close US ally, Australia is often seen as a recipient of US extended deterrence. This article argues that in recent decades, Australian strategic policy engaged with US extended deterrence at three different levels: locally, Australia eschews US combat support and deterrence under the policy of self-reliance; regionally, it supports US extended deterrence in Asia; globally, it relies on the US alliance against nuclear threats to Australia. The article argues that in none of these policy areas does the Australian posture conform to a situation of extended deterrence proper. Moreover, when the 2009 White Paper combines all three policies in relation to major power threats against Australia, serious inconsistencies result in Australia's strategic posture—a situation the government should seek to avoid in the White Paper being drafted at the time of writing. 相似文献
