This article examines the Chinese response to the Ebola outbreak in West Africa, first surveying Chinese interests in Guinea, Liberia and Sierra Leone. Many Chinese workers have been evacuated and projects postponed. For the first time, China has extended humanitarian aid to countries facing a public health emergency. China is under pressure to ‘do something’ but faces its own developmental challenges as well as problems of logistics. Chinese knowledge of Africa is still relatively weak and uninformed. Although China’s assistance dwarves that from the other BRICS, the Ebola crisis has revealed problems in Sino-African relations, not least the gap between rhetoric and reality. 相似文献

Animal Scavenging and Scattering and the Implications for Documenting the Deaths of Undocumented Border Crossers in the Sonoran Desert, 下载免费PDF全文

Since 1998, over 5500 people have died while attempting to cross the U.S.–Mexico border without authorization. These deaths have primarily occured in the Arizona desert. Despite the high volume of deaths, little experimental work has been conducted on Sonoran Desert taphonomy. In this study, pig carcasses were used as proxies for human remains and placed in different depositional contexts (i.e., direct sunlight and shade) that replicate typical sites of migrant death. Decomposition was documented through daily site visits, motion-sensitive cameras and GIS mapping, while skeletal preservation was investigated through the collection of the remains and subsequent faunal analysis. Our results suggest that vultures and domestic dogs are underappreciated members of the Sonoran scavenging guild and may disperse skeletal remains and migrant possessions over 25 m from the site of death. The impact of scavengers and the desert environment on the decomposition process has significant implications for estimating death rates and identifying human remains along the Arizona/Mexico border. 相似文献

By disaggregating the peasantry, this article seeks to explain the variety of experience uncovered by previous local studies of the Zimbabwean countryside. A combination of those pockets of pre‐colonial accumulation which had survived the violence of the 1890s, and the productive reinvestment of income earned in wage labour, gave rise to a distinctive pattern of rural differentiation. By the start of the 1920s a class of small farmers had emerged. 相似文献

In spite of the fact that the Portuguese Land Reform has been a radical and far‐reaching one, it has received very little attention from British social scientists. This review article looks at three books published in Portugal since April 1974 which are essential reading for anyone interested in this subject. In understanding the development of the Land Reform and the Revolution as a whole it is important to recognise the different types of regional agrarian structure which exist in Portugal. This review pays particular attention to those parts of the three books which deal with these regional questions. The cleavage between those areas in which rural wage‐labourers predominate and those in which peasant farmers are in the majority goes a long way towards explaining both the advances and the defeats of the Portuguese Revolution. 相似文献
