First results of the 14.5 GHz GANIL ECR source with the C.W. and the pulsed operation mode

International audienceA 14.5 GHz ECR source has been designed and built at GANIL in order to improve the currents, mainly the heaviest ion beam intensities (Pb, U). We give the first results obtained with the C.W operation used on the cyclotron machines, and those we can get with the pulsed operalion mode which concerns Linacs and other machines

The socio‐material practices of the transformation of urban food markets

Focusing on the recent transformation of urban food markets in the UK, this paper applies a practice theory perspective to analyse the social practices involved in the making and doing of urban food markets. Based on fieldwork in Barnsley and Sheffield, we identify three sets of interrelated practices that are involved in the transformation of urban markets: economic diversification, traditionalisation, and technological innovation. We describe these practices as socio-material in the sense that they involve the practices of buying and selling, and other forms of social interaction, combined with the foodstuffs, infrastructure, and other material things that together constitute the contemporary marketplace. The evidence presented in this paper challenges prevalent dichotomised ways of thinking about market transformation in terms of inclusion and exclusion or modernity and tradition

Changing home and workplace in Victorian London : the life of Henry Jaques shirtmaker.

The paper uses unusually rich evidence from a manuscript life history written in 1901 from personal diaries to explore the changing relationship between home and workplace in Victorian London. The life history of Henry Jaques demonstrates the way in which decisions about employment and residence were related both to each other and to stages of the family life course. The uncertainty of work, lack of income to support a growing family, rising aspirations, the constant threat of illness, the ease of moving between rented property, close ties between home and workplace, the stresses produced by home working, and the attractions of suburbanization all interacted to shape the residential and employment history of Jaques and his family. The themes exemplified by this detailed life history were also relevant to many other people. Evidence collected from a large-scale project on lifetime residential histories is used to place the experiences of Henry Jaques in a broader context, and to show how they related to the changing social and economic structure of Victorian London

Mr. Keynes, Prof. Krugman, IS-LM, and the End of Economics as We Know It

Krugman has recently revitalized IS-LM with a number of succinct analytical pieces on his blog. The reverberations were remarkable. Economists, however, are known often not grasp the full content of their own and, a fortiori, of others’ models. This happened to Keynes in the days of high theory and to Krugman in these days. Keynes applied a defect formalism, which is here replaced by objective-structural axioms. This yields the correct relationship between retained profit, saving, and investment which in turn makes it clear after the event that the IS-part of the IS-LM construct never could bear any substantive theoretical load
