In order to understand the role of water resources in the establishment and long-term evolution of settlements investigated by the French Archaeological Mission in the UAE in the oasis of Masāfī, wells and springs of all periods, identified at the surface and in stratified contexts, were mapped and studied thanks to a multidisciplinary approach combining archaeology, geomorphology, geoarchaeology and ethnography. Our study demonstrates that:
- – The Masāfī oasis was located in a specific geological setting entailing the accumulation of groundwater resources at reachable depth.
- – The groundwater resources remained rather stable from the mid-second millennium BC to the second half of the twentieth century AD. In this respect, the apparent abandonment of the oasis during some periods cannot be explained by water depletion.
- – The groundwater resources have decreased sharply since the second half of the twentieth century AD, due to the introduction of new water extraction technologies, motor pumps and then drillings, as a result of the modernisation and industrialisation of UAE economy.

ABSTRACTThis article seeks to develop a new approach in Holocaust studies, namely an environmental history of the Holocaust. A case study of the former concentration camp at Auschwitz-Birkenau demonstrates the extent of the entanglement of the politics of memory and the politics of nature, or political ecology, to use Bruno Latour’s term. I suggest that memorials should be treated as an environment, and thus explored as an assemblage of human and nonhuman (f)actors. Analysing both the official preservation strategies adopted by the Auschwitz-Birkenau Memorial and Museum as well as artistic projects (including ?ukasz Surowiec’s Berlin-Birkenau), I consider commemorative practices’ environmental impact. My investigation thus primarily focuses on the role of the figure of the tree-as-witness in preservation work and in the use of powerful herbicides (namely Roundup) in preserving traces of the camp. This study could open the way to further comparative studies of ecocide and genocide. 相似文献

清末民初,严复与日本首相伊藤博文是留英同学的传闻开始出现,其内容和细节在流传中愈益翔实。1990年代严复一些未刊书信面世,在《致梁启超》一函中,严自称留英期间与伊藤博文同窗数载,回国后的待遇、命运则大相径庭。尽管该函两个标点本的识读有一定差异①,但考查这一时期严、梁的言行、交往、境遇,其内容有真实性,不能简单认定为伪,何况传闻的出现时间远早于此函。依据传播学原理判断,“同学说”的始作俑者可能就是严复本人。 相似文献

在我国农业合作化运动中,毛泽东著名的"停、缩、发"讲话现在有两个文本,一个是1955年3月,一个是1955年5月。通过对不同文本的史料真实性、佐证性和连续性进行认真梳理,发现毛泽东1955年3月"停、缩、发"讲话或三字方针在历史档案、当年讲话和相关文件中均无任何记载,存在若干疑点。 相似文献

ABSTRACT This article presents a study of the applicability of fast nonlinear analytical (FNA) models in predicting the global response of Chinese traditional timber-frame building with Dou-Gon under seismic excitation. Efforts are made to overcome challenges in establishing simplified calculation models, and the corresponding dynamic equations are derived considering the mechanical behavior of sliding column root, mortise-tenon joint and Dou-Gon (bracket sets). Furthermore, nonlinear time-history analysis is conducted under different seismic excitations. Through a verification study, a good correspondence is obtained with previous shake-table test results. Seismic response analysis is also conducted to investigate the energy dissipation of column root sliding, mortise-tenon joint, and Dou-Gon. Subsequently, peak responses of column root and roof under increased values of peak ground acceleration (PGA) are also analyzed. And then, seismic isolation ability and damping characteristics of the model are discussed. 相似文献
