Excavations by the joint University of Khartoum/Southern Methodist University Butana Project in the area just north of Khashm el Girba on the upper Atbara River have uncovered a series of preceramic and early ceramic occupations by hunters and gatherers which date fromca 10,000 bp toca 6200 bp. The earlier sites show no direct relations with those of similar age in the northern Sudan, while the later, early ceramic sites show only minor similarities with contemporary occurrences in the central Nile Valley. Thus, it appears that the upper Atbara River Valley played no role in the development of the Khartoum Mesolithic and that Nilotic influences were late reaching the eastern Sudan.
Résumé Des fouilles entreprises par le projet Butana dirigé en commun par l'université de Khartoum et le Southern Methodist University dans la région juste au nord de Khashm el Girba sur le cours supérieur de l'Atbara, ont découvert une série d'occupations précéramiques et céramiques anciennes de chasseurs-cueilleurs, qui datent deca 10,000 bp àca 6200 bp. Les gisements les plus anciens ne semblent pas avoir eu de relations directes avec ceux de la même période dans le nord du Soudan, tandis que les gisements plus tardifs à céramiques ne montrent que de petites analogies avec des occupations contemporaines dans la vallée centrale du Nil. Il semble donc que la haute vallée de l'Atbara n'a joué aucun rôle dans le développement du Mésolithique de Khartoum et que des influences nilotiques n'atteignirent que bien plus tard le Soudan oriental.

Abstract

Today it is estimated that over 100 million women worldwide have taken oral contraceptives since their first clinical trials in 1956. Despite their popularity, however, contraceptive pills have been under constant scrutiny for their safety since the time of their marketing. This paper considers the degree to which the pill was tested before it was introduced on to the market and challenges many assumptions that have been made about the use scientists made of women in its development. Examining the early testing of the pill, the paper makes clear that the success of the pill and its testing depended on the active co‐operation of the women who swallowed the tablet in its experimental stage. Far from being guinea‐pigs, women were thus active participants in the making of the pill.  相似文献

Unlike other scientific fields, anthropology popularizations are as likely as not to be written by scientists who are not themselves experts in the subject. This is because the subject, the scientific knowledge of our origin and patterns of bio-cultural diversity—or more broadly, who we are and where we come from—is the source of our culturally authoritative origin myths, and consequently of broad general interest in and of itself. But anthropology popularizations come with the responsibility not only to get the facts and theory correct, but as well to understand the history and embedded politics in the stories themselves.  相似文献
