A perinatal infant skeleton from the first–fourth century AD Roman villa site at Hambleden, England, shows what appear to be cut marks on the proximal part of the right femur. Gross, microscopic and micro‐computed tomography evaluations suggest that they occurred perimortem and were probably caused by a non‐serrated blade. The reason for the cuts is uncertain, but their location is consistent with the practice of embryotomy, as described in classical sources for obstructed labour due to a dead or dying foetus in a breech or leg presentation. If this interpretation is correct, this case represents a rare example of embryotomy in the palaeopathological record. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

Active adult, age-restricted communities are significant to urban history and city planning. As communities that ban the permanent residence of children under the age of nineteen with senior zoning overlays, they are unique experiments in social planning. While they do not originate the concept of the common interest community with its shared amenities, the residential golf course community, or the gated community, Sun Cities and Leisure Worlds do a lot to popularize those physical planning concepts. The first age-restricted community, Youngtown, AZ, opened in 1954. Inspired by amenity-rich trailer courts in Florida, Del Webb added the “active adult” element when he opened Sun City, AZ, in 1960. Two years later, Ross Cortese opened the first of his gated Leisure Worlds. By the twenty-first century, these “lifestyle” communities had proliferated and had expanded their appeal to around 18 percent of retirees, along with influencing the design of intergenerational communities. 相似文献

The emergence of archaeological interest in native copper in the mid-1800s developed in concert with explanations that privileged the Lake Superior area over other potential sources of copper. Most scholars have thus assumed that when copper artifacts first appeared in Northeastern North America, they arrived as finished implements or were locally made from Lake Superior raw materials. Procurement models that point to Lake Superior as the sole source of native copper have been widely accepted in the absence of systematic large-scale testing. This article evaluates the dominant model for native copper procurement and presents trace element data derived from instrumental neutron activation analysis (INAA) to determine whether hunter-gatherers in the Northeast utilized one dominant source of copper or in fact exploited a number of geological deposits. I specifically report on the chemical characterization of copper from 13 discrete geological deposits and 18 archaeological sites dating to the Late Archaic (ca. 5000–3000 B.P.) and Early Woodland (ca. 3000–2000 B.P.) periods to suggest that the dominant model for native copper procurement is oversimplified. 相似文献
