The burial of a child of two years of age from the 4th century site of Lisieux‐Michelet (Calvados, France) was examined for bone hyperplasia and a variety of mechanical deformations recognized in association with skeletal trauma. Results of DNA analysis of bone using the PCR method identified this child as female. Microscopic features of the teeth (interglobular dentine) and a sample taken from the tibia conclusively determined that this child suffered from vitamin D‐resistant rickets and possibly X‐linked hypophosphataemic rickets as its most common form of occurrence. In addition, evidence for child abuse is suspected based on the presence of cranial and tooth fractures and the appearance of successive plaque‐like endocranial (meningeal) appositions. This is the first palaeopathological report of child abuse in antiquity. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

A technological crossroads: Exploring diversity in the pressure blade technology of Mesolithic Latvia 下载免费PDF全文
Hege Damlien Inger Marie Berg‐Hansen Ilga Zagorska Mārcis Kalniņš Svein V. Nielsen Lucia U. Koxvold Valdis Bērziņš Almut Schülke 《Oxford Journal of Archaeology》2018,37(3):229-246
A long‐standing debate in archaeology concerns the sources of technological diversification among prehistoric hunter‐gatherers. This includes the study of the emergence and spread of pressure blade technology in Northern Europe during the Early Holocene. Until now, there has been little technological study of lithic collections from the East Baltic region, and our knowledge of the development and spread of this technology in the area is inadequate. This article presents for the first time a technological analysis of lithic assemblages from seven Early and Middle Mesolithic sites in the territory of present‐day Latvia, offering new possibilities for discussing pressure blade technology and research objectives connected with it. Furthermore, variation in elements of this technology is explored in relation to raw‐material characteristics through experimental flint knapping. Finally, the factors influencing diversity in craft traditions, as well as large‐scale communication and shifting spheres of interaction within Northern Europe during the Mesolithic, are discussed. 相似文献

Utilizing the 1988–1992 surveys from the Restricted-Use National Education Longitudinal Study of 1988, I find that language minority students who received English-language assistance (ELA) programs beyond the third grade reported lower English-skill acquisition and made smaller academic progress in high school than their peers. Moreover, while the type of high school ELA program (e.g., bilingual education) differently affected scholastic outcomes, students in such programs did not surpass their counterparts in monolingual-English classes on average. 相似文献

In this article, we intend to study the cultural transformations fostered by the commercialisation of inventions, a major process in the growth of markets and consumption in the XVIIIth century. Inventors' commercial strategies were based on intense mediatisation, combining visual languages (public shows, experiments, exhibitions) and print resources: advertisements, posters, tracts, how-to leaflets and users' books. Technical information and useful knowledge played a major part in the building of markets for inventions. This demension has seldom been stressed neither by historians of consumption nor by historians of technology. Yet, this literature that aimed to emancipate consumers and to develop their participative talents as m means to convince them to buy, expressed the success of knowledge in action, of operative sciences, based on gestures and verbs, on purposive action and projects. Whereas technological science (technologie) in the Enlightenment developed in treatises and dictionaries, it was also stemming from useful literature and commercial ephemeras that allowed appropriations. 相似文献

Stable oxygen isotopic analysis of tooth enamel was used to investigate seasonality and season of birth in sheep. Analyses were performed on the teeth of eight modern sheep bred at the Carmejane farm in south-eastern France and born in different periods of the year. This reference data set confirms that oxygen isotopic records in the second and third molars can be used to differentiate between sheep born in late winter and those born in early autumn. The results show that inter-individual variability in the timing of tooth formation is low for the second lower molar and more pronounced for the third lower molar in this population. The duration of the process of enamel mineralization has been estimated at approximately six months. The teeth of four sheep and two goats from the late Neolithic site of Collet-Redon in south-eastern France were analyzed using the same methodology. At this site, lambing occurred between the late winter and early spring. A slight difference appears in the seasonal sequence recorded in sheep and goat, although it cannot be determined, whether this is due to different timing of tooth development, or an actual shift in the birth period. From the distribution of slaughter ages and birth period, it is suggested that domestic caprines were killed throughout the year and that Collet-Redon was probably a permanent settlement. 相似文献
