中非发展合作:关于非洲新受援单位的思考 总被引:2,自引:0,他引:2
20世纪50年代以来,中国在与非洲国家陆续建立外交关系后,不断向非洲国家提供多领域的援助,且在1964年宣布了对非洲国家的援助政策.虽然中国对非洲援助历来以非洲整体为受援单位,但是在实施援助政策中依然以双边关系为援助落实方式.其实,非洲国家在发展进程中已经意识到,非洲次地区的发展是整个非洲发展的重要步骤,所以建立起不同的次地区组织,并且努力完善其功能.故此,中国在以非洲各国为受援单位的基础上,更应该考虑以非洲次地区组织为新的受援单位. 相似文献

The chemical composition of a fingermark potentially holds a wealth of information about the fingermark donor, which can be extracted by immunolabeling. Immunolabeling can be used to detect specific components in fingermarks; however, to be applicable in the forensic field, it should be compatible with commonly used fingerprint visualization techniques. In this study, the compatibility of immunolabeling with two different fingerprint visualization techniques, magnetic powdering and ninhydrin staining, was investigated on fingermarks deposited on glass and on nitrocellulose membranes. With dermcidin as antigen of interest, immunolabeling was performed successfully on all developed fingermarks. We can conclude that immunolabeling is compatible with magnetic powdering and ninhydrin staining, which can be of great forensic value. 相似文献

Abstract One of the most effective cultural tools used by the colonial governments in Africa to make their rule acceptable to African indigenous populations was film. In Rhodesia (now known as Zimbabwe) the colonial government created the Central Film Unit whose major aim was to teach Africans new agricultural methods. The response by Africans to this colonial initiative was mixed. Some welcomed and enjoyed the films and made use of the skills that the films popularised, but others were cynical and viewed these films as a tool to consolidate British white settler rule in Rhodesia. This article analyses six colonial films produced in the 1940s and 1950s. The article argues that through the use of colonial films, the Rhodesia government was able to persuade African communal farmers to adopt modern methods of farming. The irony of this is that the use of modern farming methods made it possible for the same colonial authorities to later blame Africans for the ecological disaster in the communal areas. 相似文献

With much information available from open sources on the internet, computer generated databases have become commonplace. The question whether computer generated databases can be protected under the sui generis database right has hitherto received little attention. This article investigates this question and finds that the substantiality of investment, the definition of the rights holder and the interpretation of exclusive rights raise fundamental issues. 相似文献
