The analysis of the maxillae and mandible belonging to a Middle Palaeolithic child has provided evidence of the early appearance of a developmental dental anomaly among Homo sapiens. The material came from the Near Eastern site of Qafzeh. In the mandible there was agenesis of the left second premolar and congenital absence of the right could not be totally excluded. Additional analyses including two presumed cases of dental development anomalies within contemporaneous prehistoric populations showed that tooth agenesis also can affect the anterior region of the mandible, and could be clearly separated from ante-mortem tooth loss caused by trauma. © 1998 John Wiley & Sons, Ltd.  相似文献

In national narratives of ‘Malayness’, a specific language (Malay) and religion (Islam) have become key aspects of an identity that excludes migrants and those of ‘questionable’ sexualities. Consequently Filipina migrants working in the nightlife industries in East Malaysia have been subjected to disciplinary discourses of ethnicity and sexuality that underpin these national narratives. Attempts to tighten migration laws and curb nightlife activities have resulted in a racialisation of Filipina migrant sexualities. Using ethnographic methods, this article explains the impacts of dominant state and public discourses of migration, ethnicity and gender, which Filipinas encounter in their everyday lives in their destination country. In the process the article also reveals how Filipinas resist these discourses and hence participate in the formation of their subjectivity.  相似文献

A new methodology based on major and trace element analyses of slag inclusions is proposed to determine (or exclude) the provenance of iron artefacts. It is applied to verify if the Pays de Bray, a French area between Rouen and Beauvais, could have been an important supplier for the ferrous reinforcements used in the Middle Ages for the building of churches and cathedrals in these two towns. To this purpose, the behaviour of trace elements during both direct and indirect operating chains is studied combining experimental smelting and different analytical methods, such as SEM–EDS, ICP–MS, LA–ICP–MS and INAA, performed on archaeological samples. The chemical signature of the Pays de Bray iron ore and slag is determined considering MnO and P2O5 contents as a first rough filter and seven couples of trace elements. Then, the major and trace elements are analysed using the same methods in the slag inclusions of 32 artefacts from the Beauvais and Rouen churches, made by the bloomery process. The trace element signature of the inclusions from each artefact is compared with the ore from the Pays de Bray area. The iron used in the Rouen and Beauvais churches seems not to come mainly from the Pays de Bray.  相似文献

When and how did the first human beings settle in the American continent? Numerous data, from archaeological researches as well as from palaeogenetics, anthropological and environmental studies, have led to partially contradictory interpretations in recent years, often because of the lack of a reliable chronological framework. The present study contributes to the establishment of such a framework using luminescence techniques to date a Brazilian archaeological site, the Toca da Tira Peia. It constitutes an exemplary case study: all our observations and measurements tend to prove the good integrity of the site and the anthropological nature of the artifacts and we are confident in the accuracy of the luminescence dating results. All these points underline the importance of the Toca da Tira Peia. The results bring new pieces of evidence of a human presence in the north-east of Brazil as early as 20,000 BC. The Toca da Tira Peia thus contributes to the rewriting of the history of the peopling of the American continent.  相似文献

In recent years, there has been a tendency to correlate the origin of modern culture and language with that of anatomically modern humans. Here we discuss this correlation in the light of results provided by our first hand analysis of ancient and recently discovered relevant archaeological and paleontological material from Africa and Europe. We focus in particular on the evolutionary significance of lithic and bone technology, the emergence of symbolism, Neandertal behavioral patterns, the identification of early mortuary practices, the anatomical evidence for the acquisition of language, the development of conscious symbolic storage, the emergence of musical traditions, and the archaeological evidence for the diversification of languages during the Upper Paleolithic. This critical reappraisal contradicts the hypothesis of a symbolic revolution coinciding with the arrival of anatomically modern humans in Europe some 40,000 years ago, but also highlights inconsistencies in the anatomically–culturally modern equation and the potential contribution of anatomically pre-modern human populations to the emergence of these abilities. No firm evidence of conscious symbolic storage and musical traditions are found before the Upper Paleolithic. However, the oldest known European objects that testify to these practices already show a high degree of complexity and geographic variability suggestive of possible earlier, and still unrecorded, phases of development.  相似文献

ABSTRACT

Sociodramatic play is a central activity of early childhood, one influenced by the nature of the environment where it occurs. Using the Smilansky Scale for the Evaluation of Dramatic and Socio Dramatic Play (Smilansky and Shefatya, 1990), this study compared the frequency and complexity of the sociodramatic play of two groups of fifteen 4–5 year old children in two preschool outdoor spaces differing in natural elements, resources, and spatial characteristics. Field notes and behaviour mapping were also employed to explore potential associations between the play characteristics, and specific elements and areas of the two spaces. Findings showed the following elements supported more frequent and complex sociodramatic play: a balanced conjunction of man-made resources and significant vegetation and natural loose parts; opportunities for seclusion and lack of overcrowding; linking pathways and open-ended design. The findings have implications for the design of outdoor spaces that support the frequency and complexity of children’s sociodramatic play.  相似文献
