As human milk is exceptionally low in strontium-calcium () ratios, but solid foods are relatively high, it should be possible to examine the pattern of dietary supplementation and the age of weaning in prehistoric groups by reference to the ratios of juvenile skeletons. The data are presented that support this rationale, along with an investigation of the Sr/Ca values of juvenile and adult skeletons from a medieval Arab graveyard. The data from these skeletons are shown to coincide with the age-curves expected in theory, suggesting that new palaeodemographic information is indeed obtainable from studies. However, until further research is conducted, the technique provides a functional estimate of weaning patterns that is only suitable for comparative purposes. Additional research should clarify the relationship of functional to actual estimates of dietary supplementation and weaning. 相似文献

Morphological analysis by light and electron microscopy was conducted on wine residues from second century Roman amphorae found in Myrmekion (Ukraine). The results of the archaeological samples were compared with residues formed in bottles of wine from Tuscan vineyards, corked between 1969 and 1977 without filtration and enzyme or biochemical processing. Staining and histochemical observation of the archaeological and recent residues detected nucleic acids. Molecular analysis was also performed using nuclear microsatellite SSRs markers having high polymorphism to study genetic relationships. Genotype profiles of archaeological and recent residues were compared with contemporary cultivars in a data bank. Low homology of genotype profiles of all residues, and oral evidence, confirmed the presence of autochthonous varieties in recent wines and enabled indirect assessment of varieties detected in the archaeological material. The results confirmed that the archaeological material could be related to Sangiovese and indicated Roman wine trade as far afield as Ukraine, whereas the recent residues provided evidence of disappearing native Tuscany cultivars like Gorgottesco, Mammolo, Verdello, Rossone and Tenerone, used for table wines until the late seventies. 相似文献

There is a great deal of variability in how osteoarthritis is scored and analysed. This paper compares several commonly used techniques of data presentation and analysis, using a prehistorical skeletal sample from the southeastern USA. It finds that these methodologies result in greatly different outcomes, not only in the overall frequencies of lesions, but also in the statistical findings and in which joints apparently have the most arthritis. It is unlikely that a consensus will quickly develop on how to deal with osteoarthritic lesions, owing to widespread disagreements on even such basics as scoring. In the interim, the best way to ensure comparability of studies is to present the most complete and least manipulated data possible, along with easy-to-interpret summary scores. 相似文献

AbstractThis article offers a brief overview of the development of francophone feminist geography in Canada. We begin by situating the review geographically, in order to explain our focus on francophone feminist geography produced in Québec. We then discuss the origins of feminist francophone geography in the 1980s, highlighting the central role of the student reading group, the Collectif de lecture sur l’espace et les femmes, that was formed during that period at l’Université Laval. Tracing the research trajectories of feminist geographical research since then, we argue that feminist geography has become more diverse, but ironically less visible. We conclude by highlighting the central role that graduate and undergraduate students play in pushing forward a feminist geography agenda as they demonstrate the importance of feminist politics era through their research and activism. 相似文献
