Recent refinements in radiocarbon sampling procedures have enabled a more robust absolute chronology for the Mesolithic in the Rhine–Meuse–Scheldt area of northwest Europe. These refinements have allowed for a new chronological sub-division of the Early and Middle Mesolithic periods. Results of this research have indicated that the Middle Mesolithic period was bound by two Early Holocene cooling events, one at 9300 cal. BP and the other at 8200 cal. BP. These results enable a critical evaluation of the role of chronological precision in the investigation of contemporaneity between abrupt climate change and hunter–gatherer sociocultural change. In this paper we focus on the variable chronological resolution of the Early to Middle and Middle to Late Mesolithic transitions in the RMS area, and the role of this variable resolution in our ability to investigate the contemporaneity of these two transitions with different Early Holocene abrupt cooling events. This paper highlights two central challenges facing archaeological investigations of the relationships between climate and culture change: first, the requirement of tight chronological overlap between climate and culture change events and consideration of leads and lags in ecosystem and subsequent human responses to climate change; second, the equifinality problem and the separation of the impact of gradual from punctuated environmental change on human societies.  相似文献

Wars and their aftermaths frequently transform land use and ownership, reshaping ‘post-conflict’ landscapes through new boundaries, population movements, land reforms and conditions of access. Within a global context of controversial land concessions and farmland acquisitions, we bring to light the continued salience of historical memories of war in the ways land conflicts are being negotiated in Laos. Considering circumstances at different scales—from bilateral government relations to village-level claims—we find that political capital linked to memories of wartime affiliations have crucial spatial and place-based connections, and that they affect the ways investors, government officials and villagers negotiate over land concessions. Ethnographic evidence, spatial analysis and a survey of expatriate development workers engaged with land issues in Laos suggest that such ‘political memories’ are an important but often overlooked factor in shaping an uneven concessions landscape. We discuss implications for foreign development organizations that tend to privilege technical and legal aspects of land management over such political dimensions.  相似文献

This paper brings recent research on the geographies of commodities and the politics of ethical consumption to bear on contemporary spaces of violence. Focusing on the discourse of “terror”, it discusses the tactics and ambivalences of a human rights advocacy campaign seeking to stop the financing of belligerents by the diamond trade. I argue that the campaign successfully reconnected “violent” spaces of exploitation and “peaceful” spaces of consumption and achieved significant trade reforms in the diamond sector. Yet, with its inclusion of racialized images of Africa, its responsiveness to policy compromises and its overtaking by savvy marketing by Western mining companies, the campaign and its mediatization also had ambivalent outcomes: burnishing the “reputable” character of Western industrialized mining interests at the expense of their historical accountability, indiscriminately associating terror with poor young African men, and overlooking state violence.  相似文献

法国地理学界对旅游资源的研究方法至今经历了三个阶段,先是实证主义,后来结合了现象学,再后来引入组织社会学中的参与者理论并提出旅游者中心说.文章结合中欧案例,通过比较这三种理论揭示了这一发展进程中的理论进展,提出研究旅游资源问题既不能只着眼于资源本身,也不能只停留在一些现象上,而应特别重视旅游的最重要的参与者一旅游者及其活动.文章还研究了中国现行的旅游资源研究理论,认为国内目前依然通行实证主义研究方法,但部分学者巳开始采取现象学的研究视角,个别学者的理论已在某些方面突破了现象学的理论范畴,接近法国MIT学派倡导的某些观点.  相似文献
