The HF ionospheric modification (heating) facility at Ramfjordmoen will become a part of the EISCAT association from January 1993. This paper, which is intended for the new user, describes the technical capabilities of the facility and the broad range of geophysical and plasma physical experiments which are possible. An overview is presented of the physical effects that a powerful HF electromagnetic wave incident on the ionosphere can produce on timescales ranging from tens of microseconds to minutes in height regions ranging from 50 to hundreds of km. Emphasis is placed on the practical implementation of ionospheric heating experiments using the EISCAT incoherent scatter radars as the main diagnostic, but other diagnostic techniques using ground-based radars, radio links, radio receivers, photometers, rocket and satellite instrumentation are also described. A companion paper presents in greater depth some of the current scientific issues being addressed in ionospheric modification research.  相似文献

As anthropologists and other critics of capitalism turn their attention to the controversial and burgeoning corporate social responsibility (CSR) movement, most focus on conflicts in community relations and environmental degradation. Few scholars have examined equally pertinent questions of labor restructuring, even though these transformations emerged at about the same time as the rise of CSR. In this article, we draw on research in two Peruvian mining communities to explore the potential contradiction between the simultaneous mandate for corporations to present themselves as responsible employers, on the one hand, and the drive to rationalize labor and reduce financial responsibility for the workforce, on the other. We suggest that for both corporate officials and some scholars, this tension remains a latent one because CSR discourses and documents generalize corporate interests as the interests of mines as a whole.  相似文献

This article explores a classic dilemma concerning the extent to which anthropologist fieldworkers may influence their fieldwork hosts. This dilemma arose in the course of the author's research on kolam drawing practices among diaspora Tamils in the UK. Kolam constitute a popular visual practice among Tamils in India and Sri Lanka, but less so in the diaspora. However, the researcher's interest in kolam practice began to awaken an interest on the part of diaspora Tamils in the UK and affect the very practices researched. Does this constitute an intervention or might it be considered an appropriate form of inspiration? The article makes a contribution to the literature on ethics and on diasporic communities, whose members, although reticent to perpetuate practices that might upset their host society, may nevertheless defer to researchers with specialist knowledge of their homeland.  相似文献

The Eurozone crisis has highlighted the problems of European economic integration, but what effects is it having on social cohesion in the European Union? Using symbolic, historical and anthropological perspectives this article examines the relationship between the single currency and European citizenship. I argue that the roots of the crisis lie in the euro's origins. Economic and monetary union (EMU) was an assemblage of two very different rationales: one economic and based on neoliberal assumptions, the other political and geared towards forging social cohesion among Europeans. Binding Europe through a common currency was always a risky endeavour, placing heavy expectations on the identity‐effects of money. EU leaders also seemed curiously oblivious to the possible negative effects that weaknesses in the euro might have for European solidarity. Drawing on theories of money and its role as a technology of citizenship and symbolic boundary marker, I argue that the euro continues to symbolize European integration, only now it has come to symbolize the cleavages and tensions that divide Europe. Paradoxically, one effect of the Eurozone crisis is not fragmentation but an acceleration of the deepening of European economic governance. However, the centralization this entails imposes heavy costs on the EU's peripheral members and raises concerns about the future of democracy in Europe.  相似文献
