Between March and May 2010 a series of school killings took place in mainland China. This article explores media discourses on the school killings and examines three cases in detail. It connects the search for underlying reasons and responsible authorities in relation to the murders with the wider search for ‘society’ in contemporary China, and concludes by emphasizing the gap between the official promotion of the idea of ‘society’ as a cohesive moral community and a parallel popular understanding of the contemporary Chinese social world as a savage wilderness. 相似文献

The focus of this article is on product innovations introduced by firms (establishments) and the collaborations they enter into with other firms and organizations in carrying out this activity. The theoretical framework combines innovation theories with the literature on regional innovation systems and the knowledge-based economy. Empirically we have investigated characteristics of collaboration among manufacturing establishments in the region of East Gothia in Sweden, with specific focus on the number of employees involved in the innovation projects, mechanisms of knowledge transfer between organizations, as well as financing and patenting in relation to product innovations. 相似文献

The modification of the raw clay by the potter to produce a paste suitable for the intended purposes adds a layer of obfuscation to the problem of provenancing the original clay source by chemical fingerprinting. By preparing different pastes from the same commercially available raw clay and their chemical analysis by Instrumental Neutron Activation Analysis, an experiment under controlled conditions (tempers, mixing ratios, firing temperatures and sampling methods) sheds light on the influence of different tempers. 相似文献

The effects of medieval agrarian crisis on settlement and population were considered in a major interdisciplinary research project in Scandinavia during the 1960s and 1970s. Within this project, there were significant differences in methods used to calculate the extent of farm desertion between historians in the participating countries. The reliance on written source material within the Swedish team reflected the dominant approach amongst historians who made less use of map and landscape evidence than others. In this renewed investigation of the magnitude of farm desertion in the Late Middle Ages, focussing on the province of Jämtland in central Sweden, field survey of the physical landscape and some three thousand historical maps are used as evidence, alongside conventional written sources, such as official letters and taxation documents. The results indicate that the extent of farm desertion in medieval Sweden has been underestimated because Swedish scholars generally eschewed the use of the retrogressive method, which their Norwegian counterparts had been using since the 1940s. There is therefore good reason to reassess the desertion rates of medieval farms in other parts of Sweden as well, using traditional geographical source materials together with the documentary sources usually favoured by historians This may also hold for other parts of Europe as well. The rate of desertion is discussed in a wider context of settlement contraction and expansion in central and peripheral areas of Sweden, including the long drawn-out process of reclamation of the deserted farms (ödesbölen). 相似文献
