We present a new curve of the directional secular variation of the geomagnetic field in Western Europe between 1500 bce and 200 ce . Its computation relies on a Bayesian framework. The fast secular variation during the Late Bronze and Early Iron Ages makes archaeomagnetic dating efficient with a respective precision of 150–200 and 60–100 years during these periods. The Bayesian method also provides posterior date distributions that refine the dating of reference data, especially during the period of the Hallstattian radiocarbon plateau. Archaeomagnetism becomes a valuable alternative to radiocarbon and will help to improve the archaeological chronologies.  相似文献

Classical industrial districts' literature is not focused on the role played by external ties but gives more importance to the local districts' endogenous development. Global value chains connect clusters to other external agents through external linkages and constitute a framework to analyse the complex inter-linkages between clusters and other external agents. In the field of the external ties and the global value chain approach Academia is primarily focused on the ties which link clusters in developing nations to global markets, although global value chains also consider connections between clusters in similar activities and even when both are located in developed nations. Thus, external linkages are mainly performed by multinational enterprise (MNE) affiliates which play fundamental role of knowledge diffusers and absorbers in the process of knowledge exchange throughout global value chains. The work examines the process of knowledge exchange between clusters through external ties using the global value chain approach. For this purpose, empirical work is conducted with 22 face-to-face interviews to provide a case study about a leading cluster in the global ceramic tile industry. Results show that the basic knowledge to successfully compete is locally originated, although it can be complemented with global knowledge learnt or generated in other territories. MNE affiliates bridge structural holes through external ties and reduce knowledge asymmetries within global value chains. External ties on network-based governance chains exist, matter and affect clusters allowing upgrading even between developed nations.  相似文献

ABSTRACT

During the first half of the twentieth century, northern Quebec was under federal jurisdiction. Tired of English Canadian supremacy and increasingly aware of northern Quebec’s considerable natural resources, which could provide a solid basis for future moves toward independence, the Quebec government began to take over responsibility for its northern territories in the 1960s. It established a regional administration to take charge of its northern affairs and sent officers to northern Quebec’s remote communities. For two decades, both governments administered the region and imposed two political systems on the local Inuit. This article is based on lengthy fieldwork and archival research. The historical background is described to show how Nunavik has developed as a political and social entity through its relationships with the Quebec and Canadian governments. This conflictual situation has created tensions in the Inuit community, resulting in political dissensions over the goal of self-government. Finally, this article details how the Inuit have exploited federal–provincial tensions to further their own interests.  相似文献

A sedimentary deposit discovered at Kerguelen Islands in 1988 is interbedded in the Cape MacLear cliffs, near Mont Rond (Ronarc'h Peninsula). The age of this oceanic deposit is considered to be lower to middle Miocene as indicated by isotopic dating of both the underlying and overlying basalts. This deposit yields a fauna essentially consisting of molluscs (bivalves, gastropods) and crustaceans (cirripedes). This fauna exhibits some similarities to Miocene to Recent austral faunas (New Zealand, Argentina) as a result of the establishment of the Antarctic Circumpolar Current. However, it has no species in common with the extant Kerguelen fauna. The Mont Rond fossil assemblage is best compared with either of two types of extant communities developed on a bare sandy sea floor where infaunal species are dominant, but most likely to an opportunistic one in depths from approximately 10 to 80 m.  相似文献

The discovery of numerous cat remains, including many kittens, in various buildings (i.e., domestic house, cistern, mosque) of the ancient harbour of Qalhāt in Oman is unique among faunal assemblages in the medieval Arabian Peninsula. In this study, a zooarchaeological and taphonomic analysis (ageing, skeletal element distribution, pathologies) is conducted to understand the origin of the cats and to deepen our understanding of human–cat relations. Thus, concerning the cats found in Qalhāt, two hypotheses may explain their presence: they took refuge in one of the buildings and died in situ before the complete destruction of the structures, or the corpses may have been dumped in the structures during a phase of their abandonment, very likely for health reasons.  相似文献
