In contemporary Europe, national identities are fiercely contested and governments have sought ways to strengthen national identification. Notwithstanding this European pattern, government policies are implemented differently and belonging to the nation comes to involve different images and enactments across contexts. In the Netherlands, especially, belonging to the nation is at stake in many high‐profile public and political struggles. In this context, a pervasive public imaginary we call ‘dialogical Dutchness’ represents the Dutch as distinctly anti‐nationalist and open to difference. This raises the question whether national boundaries actually become traversable in view of such a national imaginary. How does one become a Dutch subject if Dutchness entails not being nationalist? Through the analysis of a Dutch social policy practice – state‐provided parenting courses – we show how dialogical Dutchness is negotiated and transformed in actual enactments of national difference and belonging. Although dialogical Dutchness foregrounds openness to difference and valorises discussion, it comes to perpetuate and substantiate boundaries between those who belong to the nation and those whose belonging is still in question.  相似文献

Ancient wool textiles recovered from archaeological sites are in many cases originally dyed with natural organic dyestuffs from vegetable sources. These include among others woad (Isatis tinctoria L.), weld (Reseda luteola L.), and madder (Rubia tinctorum L.). These dyestuffs could be a threat to the use of the strontium isotopic system as a tracer for provenance studies of ancient wool, because they could potentially contaminate the signature of the textile's raw material. We present a novel method which allows for efficient removal of organic dyestuffs in wool prior to strontium isotopic analysis. Our method is based on an oxidative release of the dyestuff constituents by ammonium peroxodisulfate [(NH4)2S2O8] solution, combined with hydrofluoric acid (HF) that has shown to effectively remove/dissolve adhering dust micro-particles. Our multi-analytical results show that such a pretreatment is capable of removing >98% of the originally present organic dyestuffs without significantly destroying the wool structure. The strontium isotopic ratios of the residual wool fraction after the application of the pretreatment are sensitive to the origin and, therefore, can be used as tracers for the provenance of the raw material. We propose to apply this method to ancient wool textiles in which positive identification of organic dyestuff constituents by High Performance Liquid Chromatography (HPLC) was made.  相似文献

It is now commonly accepted that technology is, to its very core, a social product through which we can explore cultural choices. This cultural dimension of technology will be examined with reference to the introduction and use of the potter’s wheel at Phylakopi on Melos (Greece) during the Late Bronze Age. At this site, the co-existence of two different manufacturing techniques was so deeply embedded that, despite the presence of hybrid vessels, many aspects of the pottery production had become linked to either a local (hand-built) or Minoanising (wheel-thrown) tradition. It will be argued that the traditional hand-building technique was associated with individual and rooted facets of the Melian identity (such as kinship, social class, or gender). Reasons for the initial stimulus for adoption of the potter’s wheel are considered to lie in its potential for competitive social practice through association with exotic, symbolically laden technologies, craft products and consumption rituals. The gradual application of the technology to ever more complex vessels, on the other hand, corresponds to the apprenticeship sequence outlined by Roux and Corbetta and may indicate an incomplete learning process or a certain lack of practice opportunities among local potters.  相似文献

Many of the sediments analysed from Tel Dor (Israel) show structural alterations indicating that they were exposed to high temperatures. This observation is consistent with the abundant evidence for use of pyrotechnology from the earliest exposed Middle Bronze Age strata through the Roman period. Such structurally altered sediments may well represent one of the more widespread and durable records of pyrotechnology, and as such could be invaluable for reconstructing past human activities. The specific aims of this research are therefore to develop the means for identifying local sediments that were altered by different pyrotechnological activities and to elucidate the varying circumstances whereby sediments were exposed to high temperatures in a Late Bronze and Iron Age 1 section.  相似文献

Abkhazia and Nagorno‐Karabakh are internationally unrecognised political entities, or so‐called de facto states, that have emerged as a result of the incomplete and contested state‐formation of their parent states and of the secessionist movements that emerged in the power vacuum of the post‐Soviet space. In addition to examining the conventional reliance on the self‐determination principle, usually followed by a call for international recognition (as often practised by emerging sovereigns), this article aims to survey whether these political entities have proved that they embody ‘rightful authority’ as such and whether they ‘have earned their sovereignty’. In other words, it attempts to examine the self‐determination claims in Abkhazia and Nagorno‐Karabakh based on legitimacy criteria that are widely accepted for liberal democratic societies using an analysis of the respective issues as they were represented in focus‐group discussions in these two regions.  相似文献

The paper addresses the relation between geographical location of firms and collaboration with knowledge intensive service providers on product innovation in a small country setting. The analysis shows that even in a small country with limited geographical distances firms located in peripheral areas are less likely to be broad users of collaboration with knowledge intensive service providers in the process of product innovation than firms located in major urban areas. However, it is only amongst firms located in the periphery that collaboration strategy seems to matter in the sense that differences in development in employment can be detected between broad and rare users of collaboration.  相似文献

A long‐standing debate in archaeology concerns the sources of technological diversification among prehistoric hunter‐gatherers. This includes the study of the emergence and spread of pressure blade technology in Northern Europe during the Early Holocene. Until now, there has been little technological study of lithic collections from the East Baltic region, and our knowledge of the development and spread of this technology in the area is inadequate. This article presents for the first time a technological analysis of lithic assemblages from seven Early and Middle Mesolithic sites in the territory of present‐day Latvia, offering new possibilities for discussing pressure blade technology and research objectives connected with it. Furthermore, variation in elements of this technology is explored in relation to raw‐material characteristics through experimental flint knapping. Finally, the factors influencing diversity in craft traditions, as well as large‐scale communication and shifting spheres of interaction within Northern Europe during the Mesolithic, are discussed.  相似文献
