Paying for water: water pricing and equity in England and Wales 总被引:2,自引:0,他引:2
Karen Bakker 《Transactions (Institute of British Geographers : 1965)》2001,26(2):143-164
Over the past three decades, the business of water supply in England and Wales has been gradually transforming from the supply of a service to citizens, to the sale of a commodity to customers. The paper provides a genealogy of concepts of efficiency and equity in water regulation over the past thirty years, prior to evaluating the implications for water consumers of one aspect of this process – the shift away from policies prioritizing inter- and intra-regional equalization (implying a principle of social equity) towards policies prioritizing economic efficiency (implying a principle of economic equity) in water charging. In closing, alternatives to the current arrangements for domestic consumers are proposed. 相似文献

Thermoluminescence dating of heated flint artefacts from the Middle Palaeolithic sequence of Chez-Pinaud Jonzac (France) places an assemblage of Quina type Mousterian into MIS 4, while the overlying assemblage of Denticulate Mousterian which is followed by two layers with Mousterian of Acheulean Tradition are all assigned to MIS 3. TL dating is used to verify the mixed nature of deposits from which diagnostic Middle as well as Upper Palaeolithic tools were recovered. The TL ages are significantly different for samples from this layer and broadly agree with the archaeological attributions. While the study is generally limited by the low number of heated samples available, a correlation with a generalized chronostratigraphic sequence is possible by including proxy data from the faunal remains associated with the lithic assemblages in question. The Quina Mousterian in southwestern France, therefore, can be placed by chronometric dating methods in MIS 4 to MIS 3. 相似文献
