Most discussions of the relationship between class and political orientation assume a coherent and homogeneous class response. Here, the new middle class of professional workers is disassembled into constituent occupations. An analysis of political preference data by means of ‘correspondence analysis’ reveals a pattern which is consistent with a structural relationship between occupational experience and political preference.  相似文献

ABSTRACT. We determine the location equilibria in a duopoly model under a novel solution concept. Typically, spatial equilibrium is described as either a simultaneous price and location game, or else as a two-stage location-then-price game. We introduce a new alternative, a two-stage price-then-location game. It is well known that no (pure strategy) equilibrium usually exists under the two standard solution concepts when products are homogeneous. We show this is also true for the new concept. We then provide numerical results for a specific functional form (the logit model) which introduces product heterogeneity into the standard framework, restoring equilibrium when the degree of substitutability between products is not too small.  相似文献

Emerging debates on the contemporary reconfigurations of work question previous understandings of the relationships among and between waged, unwaged, and reproductive labour, situated processes of value formation and/or enclosure, and the constitution and limits of contemporary capitalism. Taking Cindi Katz's notion of countertopographies and Gillian Hart's notion of relational comparison as inspirations, this Symposium draws attention to new and existing conceptual frames and modes of analysis to situate contemporary permutations of work within the shifting dynamics of uneven development in specific state, local, and institutional contexts. This Introduction summarises the interrelated and overlapping contributions that papers in this Symposium offer methodologically, analytically, and politically. The open-ended aspiration that emerges from these contributions is that close attention to heterogeneous formations of work outside the wage might help to multiply forms of vigilance and critical praxis necessary to resist the co-optation and enclosure of people's creative energies, and move toward realising the latent liberatory potentials that several of the contributions suggest.  相似文献

Many timber finds lack some or all of the outer, sapwood rings formed in the years just before felling. In order to estimate felling date once the outermost remaining ring has been dated, it is necessary to estimate the number of sapwood rings originally present. Methods doing this for oak are reviewed in the light of an intensive study of living trees at one site and an extensive study of 175 samples from living trees in North Wales and northwest England. Some methods reported in the literature are found to be invalid. A method reported by Hollstein (1965) is most reliable, with modifications for known variations in sapwood number with position in the tree. At present the best available estimate is that a value of 30 sapwood rings be used (95% confidence limits: 19–50).  相似文献
