A wooden shovel, dating from the Early Bronze Age, has survived in a remarkable state of preservation in the copper mines of Alderley Edge, Cheshire UK. Other historic timbers recovered from the mines, whilst still intact, have fared less well. An X-ray investigation into the distribution of minerals through the shovel using portable X-ray Fluorescence (PXRF) along with the use of synchrotron-based X-ray Absorption Spectroscopy (XAS) measurements of the copper and arsenic chemical speciations has provided clues to the methods by which metals from the mining environment have entered the wood of the shovel and ensured its survival. The distribution and nature of the minerals so determined suggest that the copper and arsenic, along with a significant lead content, entered the shovel during its original use in working mineral-rich deposits, rather than through the burial environment. The insights gained are expected to be applicable to other wooden artefacts recovered from ancient copper mines in other places. 相似文献

This article explores some of the reasons the 1910 Republican revolution in Portugal failed to bring about the long-term changes in national life envisioned by Party Leaders. Specifically, I argue that the Portuguese Republican Party's anti-clerical and anti-monarchical disposition ensured the continued existence of religious and political schemas it sought to eradicate, setting the stage for counter-revolution. 相似文献

This essay introduces a special issue of the Journal of Medieval History on the topic of ‘Conversing with the minority: relations among Christian, Jewish, and Muslim Women in the High Middle Ages’. Despite the fact that both interfaith relations and women's history are now well established subdisciplines within the field of medieval studies, the question of how medieval women themselves established cross-sectarian relations has rarely been explored. Documenting women's history is almost always problematic because of limited source materials, but this essay suggests that much can be learned by looking at areas where Christian, Jewish, and Muslim women shared certain facets of their lives: either by reason of social relations tied to religion and ethnicity (money-lending being a common bond between Jewish and Christian women, slavery between Christian women and Muslims) or by reason of events that connected them due to their shared sex and gender (childbirth, caring for the dead, even cosmetics). By actively looking for ‘spaces’ where women would be found, we can begin to hear the dialogues that passed among women across religious lines. 相似文献

Tacit knowledge transfer via interlocking directorates: A comparison of Canada and the United States 总被引:1,自引:0,他引:1
This paper explores geography as a contributing factor to knowledge transfer among Canadian and American firms. We argue that the knowledge networks of the two countries are moving in opposite directions. Canada's network is converging into fewer cities while the American network encompasses a greater number of cities. When the knowledge networks of Canada and the United States are explored, national and local boundaries are found to impede the movement of corporate knowledge. Prior to our discussion on its spatiality, the concept of knowledge is introduced and its relation to individuals and firms of the Canadian and American corporate network is examined. 相似文献
