Human Plants, Human Harvest: The Hidden History of California Eugenics is the first-ever exhibition on the history of eugenics in California. The disappearance of this history for half a century, and the consequent absence of a "collective menory", were the primary factors determining the exhibit's sttrcture and content. Responses to the exhibit confirmed that most visitors "never knew" about this history. The exhibit is described in some detail, with selected imagery from the exhibit reproduced. After the initial exhibition, responses of other museums and foundation officials revealed a continuing resistance to this history being publicly displayed, though the sources of resistance varied.  相似文献

The Bell site was the principal village of the Algonquian-speaking Meskwaki from ca. A.D. 1680 to 1730. Based on collected ethnohistoric data, it is hypothesized that the Meskwaki saw bears and dogs as spiritually important animals and expressed this view through differential treatment of their remains. The results suggest that discard behaviors for bears were unique and that their remains may be indicative of ritual feasting. Meanwhile, comparison of features with dog remains to features with bear remains does not show clearly comparable behaviors in most cases. Ethnohistoric and ethnographic data suggest that dogs played an important role as spiritual conduits for the Meskwaki and their neighbors, but the archaeological data are not unequivocal.  相似文献

The division of land on Dartmoor during the Bronze Age by the construction of moor-wide boundaries known as reaves represents a significant development in agricultural practice and land tenure. Previous research relating to the Dartmoor reaves suggests this way of life may have continued for no longer than 200–400 years. It has been suggested that their abandonment occurred as the result of a deteriorating climate, although there are no published palaeoclimatic reconstructions from the area. We therefore test the hypothesis that on Dartmoor, a marked climatic deterioration occurred in the late Bronze Age that can be linked to the abandonment of the reaves. A palaeoclimatic reconstruction derived from testate amoebae and peat humification analyses is presented from Tor Royal Bog, central Dartmoor, the first such record from southwest England. A major shift to a cooler and/or wetter climate is inferred from ca. 1395 to 1155 cal BC that is coincident with the period hypothesised as encompassing the abandonment. This climatic deterioration is replicated in sites in northern Britain, suggesting it was a widespread event. It is concluded that while the evidence supports a climatically forced retreat, there are a range of other socio-economic factors that must also be taken into consideration.  相似文献
