Recent studies have highlighted the long-distance transport of obsidian from the Paektusan (Tianchi or Baitoushan in Chinese) volcano on the border between China and North Korea to eastern Russia and Korea, but little is known about the role of the local population in the production and movement or exchange of this important raw material. This paper addresses this data lacuna by presenting sourcing results of 440 artifacts from 18 Late Paleolithic sites located in northeast China. A portable XRF enabled rapid non-destructive characterization of samples. The results show that although Paektusan obsidian was widely transported throughout northeast Asia, material from at least three other sources was also used. In particular, we highlight the significance of basaltic glass artifacts with the same geochemistry as sources found in the Primorye region of Far East Russia in sites from northeast China. This result indicates a two-way movement of volcanic glass artifacts between Primorye and the northeast of China rather than a unidirectional long-distance exchange system originating from Paektusan Volcano.  相似文献

The concept of the segmentary state was proposed by Southall, based on ethnographic fieldwork among the Alur people of Uganda, and subsequently applied elsewhere, notably to the putative ancient kingdom of Bunyoro-Kitara. Archaeological research, summarized here, has demonstrated that ancient Bunyoro-Kitara was not a segmentary state; indeed, neither was the political system of the Alur. The Nyoro state of the nineteenth century shows a complex interplay of political sovereignty and ritual suzerainty and of accommodation and resistance to central authority. This is understood through examination of the concepts of instrumental and creative power, the latter particularly relevant to negotiations concerning the status of women. The archaeological record of this region is then explored for evidence of earlier expressions of instrumental and creative power. Finally, the paper shows how the archaeological record of Munsa is itself an arena for modern political struggles in which protagonists harness different forms of power.  相似文献

This paper reports a preliminary investigation into the economic efficacy of two spatial frameworks—English Core Cities and the Northern Way—recently promoted by national policy makers. We ask whether they are consistent with contemporary economic process in the UK space economy through analyses of commercial multi-city law firms. The latter are treated as an “indicator sector” to define the contemporary UK space economy as practised by law firms. Within this new space of flows, the location strategies of the law firms do confirm the salience of the Northern Way (as trans-Pennine corridor) and Core Cities as part of a larger UK metropolitan space of flows. Conflating the two spatial frameworks leads us to identify hints of a rebalancing of London within a metropolitan UK space. A Manchester polycentric mega-city region is found to be the likely candidate for this role. This finding in no way impinges on London's dominant global role, and we conclude that perhaps mutuality between London and provincial cities is beginning to replace past negative dependency relations.  相似文献

Over the course of some 12,000 years, Jomon cultures developed a highly refined adjustment to the Japanese landscape. Japanese archaeologists have exposed Jomon culture in great detail, but because it rested on wild resources, the Jomon era attracts little worldwide archaeological interest. This paper discusses Jomon ecological style in light of niche construction theory to consider the conditions that gave rise to agriculture and domestication. Jomon communities clearly managed much of their landscape and many plant and animal populations. Drawing on ideas from niche construction theory, we argue that qualities of potential domesticates are a central factor in the development of agriculture.  相似文献

Kesslerloch Cave in Switzerland is one of the major Magdalenian sites in Central Europe. During a recent reanalysis of the faunal remains, we identified a cranial fragment and teeth of the domestic dog. The large maxillar fragment was directly dated to 12.225±45 bp (KIA‐33350) or c. 14.100‐14.600 BP. The finds are metrically well below the natural variability of wolves from both Palaeolithic and recent times and even show slight morphological differences to the wild wolves from the site. We argue that the maxilla fragment must now be considered the earliest indisputable directly dated evidence of a domestic dog. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

In India's 2014 general election, the Bharatiya Janata Party (BJP) secured an outright majority of seats, the first time any party has done so since 1984. This has led to claims that this is a ‘critical’ or ‘realigning’ election. Yet, most Indian elections are initially described as ‘critical’ elections, which suggests that this concept needs to be further refined to be analytically useful in India's electorally volatile and regionalised political context. This commentary conceptualises critical elections in India as those that enable the winning party to build lasting regional social coalitions. Such coalitions need to be consolidated in subsequent elections for a realignment to take place. A mastery of regional politics was crucial to the BJP's 2014 win, which does mark this as a potentially realigning election. Yet, questions remain about its ability to consolidate the coalitions that delivered this result.

2014年的普选中,印度人民党获得了绝对多数的议席,破了1984以来各政党的记录。这被看作一次“关键性”的、改弦易辙的选举。不过,印度的选举一开始也多被说成“关键性”的选举。所以,这个概念尚需推敲,以便能够用来分析印度变幻不定的选情以及地区化的政情。本文将印度的“关键性”选举界定为获胜党得建立长久的地区社会联盟。这个联盟需要在日后的选举中加固,才谈得上改弦易辙。把握好地区政治对于人民党2014年选举的胜利至关重要,它使得这次选举成为潜在的改弦易辙。但它是否有能力加固联盟以释放改弦易辙的效果,则还是一个问题。  相似文献

Summary

This essay focuses on a characteristic analytical and rhetorical strategy of the style of intellectual history practiced by Ian Hunter. It assesses the moral and political resources supplied by that strategy, as well as its implications for one particular humanities discipline, that of literary criticism.  相似文献

This article examines the success of paper‐based alternative currencies in facilitating convivial, sustainable localised economies. Based on fieldwork in the United States, the United Kingdom and Germany, it discusses the capacity of activists to create alternative forms of currency that communicate the organisers’ visions of a localised economy, before examining material practices: for whom do the currencies work, and who struggles to use them? Using insights from a diverse economies perspective, the article argues that we cannot read off the likelihood of an economic actor using the currency from the extent of their local economic embeddedness: economic actors in similar positions respond to the same stimuli in different ways, and local business owners and activists can form productive alliances to develop their shared project. The article concludes by arguing that local currencies should be used more proactively to stimulate new forms of concrete local production to meet locally identified needs.  相似文献
