The water vole, genus Arvicola, is characterised by a broad geographic distribution throughout Europe and is widespread during the late Middle and Upper Pleistocene. This genus is used as a major biostratigraphic tool within the Quaternary. Specific determinations using the Schmelzband-Differenzierung-Quotient or SDQ have identified many chronospecies within the fossil species Arvicola cantiana (Hinton, 1910). As SDQ calculation remains limited, this study reappraises the Arvicola genus in terms of morphodiversity and morphospace using outline analysis which takes into account the tooth as a whole. Outline analysis suggests that one single species of Arvicola, A. cantiana, was present during the Pleistocene. This species shows great variability with no trends or patterns in morphospace. Thus, these results call into question the reliability of SDQ for specific determinations and throw doubt on the biochronological framework based on Arvicola. 相似文献
3D surveys of archaeological elements and the construction of virtual models enable us to reconstruct historical sites. They provide useful data to select specific building processes.Photogrammetry and Terrestrial Laser Scanning (TLS) are the most common techniques to obtain synthetically heritage models. These techniques provide massive data which can only be managed by replacing them by primitive shapes, thereby obtaining more simple models and the explicit geometry of the element. Statistical and robust methods are used for this substitution, thereby avoiding the common errors due to measuring. Of these methods, the most widely used are the least-median-of-squares (LMedS) and the RANSAC method.Another computation method consists in recursive processes based on evolutive-type algorithms to adjust the model to the data captured.This paper describes two surface computation methodologies to determine the modelling of a column shaft located in temple G of the archaeological park of Selinunte (Sicily). 相似文献
In 1918, the Dutch government decided to enclose and reclaim the Zuider Zee (later called the IJsselmeer). The preceding decades had been marked by broad public debate about the utility and urgency of the project. Around 1900, its proponents constructed images of the region and of the Dutch nation in which the Zuider Zee was no longer a crossroads. They emphasized the backwardness of the area and depicted the sea as a domestic enemy, its violent storms posing a threat to the nation. Cornelis Lely’s Zuider Zee proposal (1891) promised a bright future for both the region and the Netherlands as a whole. The struggle against the water would revitalize the nation (by stimulating nation-building) and modernize its international image (perceived as a picturesque but archaic country). Opponents of the project feared the high costs and developed a counter-image: the Zuider Zee region as heartland of ‘authentic’ Dutch culture, a heritage that would be jeopardized by the project. The article concludes by highlighting the synchronicity of the non-synchronous: the Zuider Zee region was envisioned as a region living in the past, thereby constituting an ‘internal Other’ in a country undergoing rapid modernization around 1900. 相似文献
Proposing a general framework for the study of the emerging transnational society, the article critically surveys predominant disciplinary perspectives in this field, and outlines an approach based on a core/periphery model with oligopolistic competition. Within this general framework, sociology finds its specific subject in the ties that connect human beings across national borders, directly or mediated by transnational institutions. An elaborated and amended version of this approach is illustrated, among others, by the dynamics of cultural globalization and the «world language system». 相似文献

We present radiocarbon dates and preliminary micromorphological information from the Neolithic cave site of Cueva del Toro (Antequera, Málaga, Spain). This site has yielded a rich early and late Neolithic archaeological record. The late Neolithic assemblage reflects specialized handcraft activity including in situ ceramic manufacture, textile production, and food processing along with sheep and goat penning, suggesting that the cave occupants and their domestic animals shared the same living space. Until now, dating of the stratigraphic sequence was incomplete, and the function of the combustion activities carried out at the cave remained unclear. New absolute dates from the main late Neolithic domestic activity area, corresponding to the most intense Neolithic occupation of the cave, allow us to place the entire sequence between 5320 and 5170 BP (or 4250–3950 to 2σ Cal BC). Micromorphological results show that many combustion features from this site represent recurrently burnt episodes on sheep/goat stabling deposits all along the sequence, corroborating human-goat/sheep cohabitation. This practice had not been previously documented in southern Spain for such early dates. Our results exemplify the importance of characterizing archaeological deposits at a microstratigraphic scale of observation. 相似文献
