Recovering dietary and parasitological data from skeletonized burials is often overlooked or attempted without sufficient consideration of preservation possibilities, quality sampling areas or the confounding influences of post-interment processes. A case study of a skeletonized Anasazi burial is presented to demonstrate three important points. First, that macrobotanical remains can be preserved in addition to the more durable pollen and parasite eggs. Second, that the sacrum can act as a structural container for the contents of the lower digestive tract upon decomposition of the body, thereby providing a productive sampling area. Finally, that reliable interpretation of any biological remains from skeletonized burials depends upon the analysis of several control samples. Since awareness of probable data sources plays a central role in what is actually collected and analysed, it is important to alert archaeologists to the possibilities of colon content analysis from skeletonized burials. 相似文献

Hélène Cixous's 1994 play La Ville parjure ou le réveil des Erinyes , first produced at Ariane Mnouchkine's Théâtre du Soleil , insists on both theatre and feminism as valuable political practices in the face of the AIDS pandemic. Disguised in the trappings of Greek tragedy, the play reframes the scandal over the French government's complicity in the distribution of blood contaminated with HIV. As the mother of two young plague victims openly exhorts the audience to take part in righting social wrong, the Furies wreak havoc on the on-stage regime that ignores its citizens suffering. Ultimately the emphasis is not on peaceful resolution but on the critical need for action on social issues. The maternal heroine and strong women figures in this elaborate production insist on the impossibility of divorcing aesthetic considerations of theatre from its responsibility to create public awareness. 相似文献

Extensive aggregate extraction in the middle Trent valley, England, has revealed a sequence of Holocene palaeochannels associated with nationally important, and predominantly organic, archaeological remains. This paper reports observations of hyper-acidity (below pH 2), high natural magnetism and metallic sphaerules (framboids) in Holocene palaeochannel sediments at two sites in the middle Trent valley. These properties are associated with high natural remanent magnetism which has allowed the successful palaeomagnetic dating of palaeochannel fills at one of these sites (Hemington). These sediment properties are the result of the formation of ferromagnetic iron sulphides, including griegite, under conditions of high sulphur availability (from groundwater) in the presence of metallic ions and organic matter under low redox conditions, with later oxidation producing the extreme natural acidity through oxidation of disulphide (pyrite). These findings explain why, under certain groundwater conditions, alluvial palaeochannel sediments can carry post-depositional remanent magnetisation and be suitable for palaeomagnetic dating. The low pH may also be beneficial in the initial stage of wood preservation and if the sediments remain waterlogged, but probably not retard decomposition after drainage and acidification, a process that is increasingly being recognised as a threat to archaeological sites in wetland environments. 相似文献

Clovis is the best known early development in North America buts its lithic technology is poorly documented and often from animal kill sites. This evidence has been used to picture Clovis peoples as mobile, colonizing, big-game hunters and explanations of lithic technological practices have been framed largely in materialist terms. Increasing documentation suggests views about how the complex Clovis biface and blade production strategies relate to subsistence, land use, and specific kinds of mobility patterns are questionable and often difficult to test with archaeological data. We need to seriously consider the role of Clovis people's worldview in structuring their thought and technical actions. 相似文献

The goldmining project on Lihir Island in New Ireland Province, Papua New Guinea, has brought dramatic socio‐economic changes. In this matrilineal society, while women's economic contributions were substantial, their political status was not. Women's participation in decision‐making about the mine has been restricted, mainly because men have excluded them. The mining company established a women's section that has supported the development of women's organizations and a range of economic development projects. The women's organizations provide the context for new political roles for women but have experienced many setbacks that are common in such groups across Papua New Guinea. Through the Lihir experience in the first five years of the mine, this paper examines the tensions and divided loyalties that constrain women's organizations and often lead to the failure of income‐generating women's projects in Papua New Guinea. 相似文献

President John F. Kennedy's visit to Ireland in June 1963 was the first by a serving American President. Using materials from archives in London, Dublin, and Boston, this article re-assesses the motives behind Kennedy's decision to visit Ireland and concludes that it was largely a personal journey. However, the trip was not without wider historical and political significance and was surrounded by controversy. The visit was unpopular in the United States, proved a security nightmare, and provoked much discussion amongst the political leadership in Belfast, Dublin and London over Kennedy's attitude to partition. The visit marked a major development in the history of Irish-American relations as it eased tensions over Ireland's neutrality, marked a shift towards White House activism in Irish affairs, boosted Irish tourism, and fostered increased trading and cultural links between the two countries. 相似文献
