This paper presents new AMS radiocarbon dating results of six ungulate bones from the current excavation of Isturitz Cave, France, layer C 4c4. The assemblage from this layer exhibits a suite of traits closely aligned with the Early Aurignacian, but with some aspects that bear strong similarities with the Protoaurignacian, with possible in situ technological transformation. Accurate and precise dating of the late Middle Palaeolithic and the early Upper Palaeolithic periods is critical to our understanding of the possible relationship between final Neanderthals and early modern humans in Europe. As such, a rigorous set of sample selection and evaluation protocols was developed and used in this research. Among these, only cutmarked bones were selected and a total of 31 targets were made, giving a weighted average of 37,180 ± 420 BP for this assemblage and providing a terminus ante quem for the ornaments, decorated artefact and amber pendants beneath it. The implications and importance of these results to debates concerning the chronological relationship between the Châtelperronian, Protoaurignacian and Early Aurignacian and associated debates regarding hominin dispersal, interaction and the timing of technical and cultural innovations are discussed.  相似文献

The article presents an general view over the enforced migration of Austrian social scientists after 1933. The author argues that the Austrian case is a specific one: first in consequence of the two successive dictatorships, second because of the devastating consequences of the emigration movement for the Austrian scientific community and culture. Only a few of the refugees returned to Austria after 1945. Further could be demonstrated that the Austrian refugees were quickly promoted in the scientific world of their exile countries, by way of comparison — especially in the United States.  相似文献

Anti-extractivist critique still positions Indigenous people as protagonists of counter-modern political sentiment, whether as opponents of modernity's processes of productive rationalization and economic integration, or as embodying ontologies that reject modernity's conceptual separation of humanity from natural resources. Indigenous anti-extractivism is thus said to represent a rupture of modern politics in that it exceeds politics as we know it. Yet the calculus of modern politics remains central to Indigenous responses to resource extraction, even in social contexts where non-modern ontological suppositions are widely adhered to. This is illustrated through an ethnography of Indigenous mining in the southern Ecuadorean Amazon and national-level electoral data showing the sweeping support of Indigenous people for former leftist President Rafael Correa's ‘neo-extractivist’ programme. This persistent modernity of Indigenous resource politics exposes the fallacy of projecting counter-modern sentiments onto Indigenous peoples.  相似文献
