Using data on the ‘career’ paths of one thousand ‘leading scientists’ from 1450 to 1900, what is conventionally called the
‘rise of modern science’ is mapped as a changing geography of scientific practice in urban networks. Four distinctive networks
of scientific practice are identified. A primate network centred on Padua and central and northern Italy in the sixteenth
century expands across the Alps to become a polycentric network in the seventeenth century, which in turn dissipates into
a weak polycentric network in the eighteenth century. The nineteenth century marks a huge change of scale as a primate network
centred on Berlin and dominated by German-speaking universities. These geographies are interpreted as core-producing processes
in Wallerstein’s modern world-system; the rise of modern scientific practice is central to the development of structures of
knowledge that relate to, but do not mirror, material changes in the system.

AbstractThis opening article examines the relationship between community sport and social inclusion in research and practice. We discuss the notion of community sport, its multifarious meanings and diverse applications in different parts of the world. We further explore the conceptual and practical links between community sport and different conceptions of social inclusion. In doing so, the article draws together key themes, issues and debates addressed in the collection of articles in this special issue. We conclude by formulating implications and directions for future research and practice. 相似文献

In this article, we build on Stigler and Becker’s (1977) “consumption capital theory” and propose a novel conceptualization of film quality for the analysis of motion picture franchises. Generally, this theory predicts that the utility consumers derive from a particular good or service increases with prior consumption. We test our theoretical conjectures by drawing on the population of sequels that were running in the US between 1992 and 2011. The empirical results point to the explanatory power of the proposed framework. Film executives may use our findings to improve the profitability of their sequel productions. From a theoretical point of view, consumption capital theory allows for a more refined analysis of sequel performance along different dimensions. Moreover, it may provide a fruitful basis for the analysis of other serial media content, including books, TV, music, and games. 相似文献
