The dynamic systems framework may be considered an alternative to traditional approaches that study technological change. The benefits of this framework are simultaneously methodological and metaphorical. Methodologically, the framework provides a coherent analytic process for studying empirical data to explain the complexity of technological change. Metaphorically, the framework appeals to local-scale interactive mechanisms to account for the origins of change. Applicability of the dynamic systems framework for studying technological change is illustrated with an archaeological case study: the emergence of the potter's wheel in southern Levant during the 4th millennium BC. 相似文献

AbstractSpatial proximity is credited with numerous virtues in the economic literature. In particular, for a company to be located near other companies is seen as conducive to the development of business relations. Spatial proximity is also considered to contribute to the quality and efficiency of these relations by facilitating face-to-face meetings that foster the exchange of complex knowledge and, in particular, the emergence of innovation. This article explores the notion of spatial proximity in intercompany relations, its capacity to facilitate exchange, as well as the link with the methods of communication employed (information and communication technologies and face-to-face). It is based on a distinction between real proximity (the spatial distance between firms), perceived proximity (the spatial distance as evaluated by the firm itself) and active proximity (spatial proximity that facilitates the exchanges). The data come from a survey conducted in 2008 with more than 2000 firms located in the Brittany region (France). The findings emphasize the relative nature of the notion of spatial proximity and the distinction in some cases between real and active proximities, and show that the positive perception of the role of spatial proximity is sustained by the increased face-to-face contact it entails. 相似文献

The involvement of diasporas in the advent of modern nationalism is not a new phenomenon: already in the 19th century some diasporas wanted to ‘normalise’ their national existence by building a state of their own. However, with the growing globalisation trend in the 199'0s , especially in the areas of transportation and communication, Benedict Anderson put forward the idea of long‐distance nationalism (LDN), as a new way of linking diasporas and the national project and thus creating a more intense sense of belonging. LDN has been characterised by him as having two main features: its unaccountability which allows for intense political radicalism, and its instrumental function for strengthening ethnic identity in the diaspora and thus a sense of belonging. I will test those hypotheses in the case of the archetypal Jewish diaspora. 相似文献

In this article, the authors discuss the emergence of an integrated city-system in France one century before the Industrial Revolution, starting from two different databases, the postal roads relays and the cities and towns populations, between 1632 and 1833. They first model historical distances, weighted by elevation and connectivity (measured as a conductance). A major transformation of inter-urban exchange space is then enlightened, with new roads systematically privileged in the northern part of France and the largest cities, but avoiding mountains. They then study territorial integration processes on two different scales: the national, with the diffusion of hubs (characterized by a high betweenness centrality) all over French territory, and the regional, with the emergence of regional city-systems (modeled by a Reilly equation) in the northern part of France. The role of medium-sized cities as necessary links for connecting local and national scales is emphasized in most results. 相似文献

This paper reports a series of radiocarbon dates on bone samples coming from the Mousterian of Acheulian Tradition (MTA) Layer 3 at the top of the Pech de l'Azé IV (Pech IV, France) Middle Palaeolithic sequence. All of these samples showed evidence of human impact, and they were prepared using current pre-treatment techniques to remove or identify contamination. The results indicate that the MTA at Pech IV started prior to the current limit of radiocarbon calibration (circa 50 ka BP) and ended by 45 ka cal. BP. These dates are supported by additional TL and ESR dates from the sequence, confirm previously suggested correlations between Pech I and IV, and generally fit within the known age range for the MTA. The oldest dates reported here may also lend support to still older TL dates for the MTA that taken together suggest that the MTA extended from late MIS 4 or early OIS 3 through to the end of the Middle Palaeolithic in southwest France. 相似文献
