Retouchers are fragments of bone used during the Paleolithic to strike stone flakes in order to transform them into retouched tools. Our experiments show that the mark produced on retouchers differs depending on whether they were used to strike flint or quartzite. Our results suggest that numerous pits, most often with an ovoid form, characterize the retouching of quartzite flakes. Most of the scores produced with this material have a sinuous morphology with rough interior faces. The areas with superposed traces have a pitted appearance. On the other hand, the retouching of flint flakes, produces pits that are most often triangular in form. Most of the scores have a rectilinear morphology with smooth interior faces and their superposition results in the formation of hatch marks. There is also a relationship between the characteristics of the mark and the relative state of freshness of the retouchers. The validity of the criteria identified was confirmed by a blind test. These diagnostic criteria were applied to archaeological retouchers from the Mousterian site of Noisetier Cave. The results obtained improve our knowledge of the technical behaviors of Neanderthals and allow us to address questions concerning their techno-economic implications. 相似文献

In this paper we use a small number of in-depth interviews with parents with primary school children to examine social mixing and friendship practices in two super-diverse North London boroughs. In these complex geographical contexts, characterized by gentrification processes and old and new migrations, we suggest that primary schools are convergent places where adults and children from different backgrounds are likely to meet and interact, and the paper explores the extent to which adults and children, thrown together in and through these sites, negotiate relationships with those who are differently socially and culturally situated to themselves. Informed by the interview narratives, the paper highlights the importance of focusing on the micro, quotidian ways in which differences in social and/or ethnic background shape those relationships and it explores some instances of the ways in which those differences are routinely encountered, managed and/or avoided. In this way the paper contributes theoretical and empirical nuance to current concerns around difference and diversity and the interactions of complex urban populations by ‘adding’ social class to everyday multiculture perspectives and everyday multiculture perspectives to urban middle class debates. 相似文献

This article presents a rare inside view of a unique project currently underway in China to study and preserve the memory of possibly the single most seminal event in Chinese modern history, the War of Resistance against Japan (1937-45). The article introduces a multi-faceted program to preserve the wartime cultural heritage; the work is ongoing in the thriving western metropolis of Chongqing, once China's bomb-torn wartime capital and international Allied command center. It describes how, seven decades after World War II, scholars, cultural workers, government experts, and artists in China are joining hands in an unprecedented, all-encompassing project to record, restore, and recount the extraordinary legacy of China's War of Resistance in its local, as well as national and global contexts. 相似文献
