A method is proposed for recording linear enamel hypoplasia (LEH) present on archaeological pig teeth. The methods described have been developed and tested on material from five archaeological sites of a wide range of periods; Durrington Walls (UK), Wellin, Ename, Sugny and Londerzeel (Belgium). Recommendations are made on what teeth, surface, cusp, and side to record, as well as on details of the visibility, the identification and the measurement of LEH lines. Problems encountered with the application of the recording protocol to the five case studies are detailed, and possible interpretative drawbacks are discussed. © 1998 John Wiley & Sons, Ltd.  相似文献

Rooflessness in London emerged as a media issue and political problem during the 1980s. While "rough sleeping" undoubtedly increased, numbers are hard to quantify because studies are unreliable, use different categories, and people seamlessly drift from one category to another. This article analyzes the causes of rooflessness in London, focusing on central government policy change at a time when London, atypically among major cities, had no overarching metropolitan government. The creation of multiple quasi-governmental agencies and charities whose responsibilities for homelessness overlap does not help coordination. Many short-term initiatives have been attempted, but solving rooflessness may require more radical changes if endemic homelessness is not to be the condition of the post-welfare state.  相似文献

This research uses an alternative economic composition methodology that classifies 52 Idaho rural communities. This methodology classifies communities as dependent, diversified, or post-industrial. A survey was mailed to elected officials (mayors and city council) from the sample of 52 rural communities to examine whether there is a relationship between environmental policy support and economic type. One hundred and thirty-three respondents (48%) returned the surveys. The findings reveal that the economic composition of the community was related to views of environmental policy on 7 of 16 measures while controlling for gender, political ideology, and age.  相似文献

This article contrasts two major debates in book form on the Israeli–Palestinian conflict, so central to French political discussion today—the ‘quarrel’ between Alain Badiou (with Cécile Winter, in Circonstances 3: Portées du mot ‘juif’) and Éric Marty (Une querelle avec Alain Badiou, philosophe), and the debate between Régis Debray and Élie Barnavi (À un ami israélien, by Debray with a response from Barnavi). The Badiou/Marty exchange is hostile and polarised, Badiou arguing strongly against the existence of a separate Israeli state and Marty vehemently in its favour, while À un ami israélien evidences what I describe as Debray's post-Zionism in dialogue with Barnavi's Left Zionism. What emerges from the two exchanges is, it is argued, a taxonomy of attitudes towards Israel substantially more complex than the traditional, and often misleading, polarity between ‘Zionist’ and ‘anti-Zionist’.  相似文献

This paper outlines the first methodology for recording dental enamel hypoplasia in the high‐crowned dentition of modern and archaeological caprine teeth. The method has been developed and trialed on five caprine populations from Orkney (UK); two modern populations (Shetland and North Ronaldsay breeds) and three Neolithic assemblages from the archaeological sites of Knap of Howar, Skara Brae and Holm of Papa Westray. Problems associated with differential tooth wear, as well as the presence of coronal cementum, are discussed, and recommendations are given on the identification and recording of hypoplastic dental defects in caprines.

This article utilises male occupational data recorded in the baptism registers of England and Wales, 1813–1820, to locate the geographical distribution of the textile manufacturing industry at that time. By comparison with female and male occupations abstracted from the 1851 census, it shows that the location was set at least as early as the second decade of the nineteenth century, and before the introduction of steam power or the mechanisation of weaving could have played significant roles. By 1813–1820, the once great regional textile centres of East Anglia and the West Country were no more. Approximately sixty-six per cent of fathers employed in the textile industry lived in Lancashire and the West Riding of Yorkshire. Moreover, textile manufacturing was further concentrated into a small number of parishes. Two-thirds of fathers lived in thirty-six parishes, and fifty per cent resided in only nineteen parishes. An association between the location of the main textile parishes and the proximity of the coal measures is evident. The registers contain a large number of entries for male spinners, reflecting the extent of uptake of Samuel Crompton’s spinning mule. The data confirm that the mule was dominant in cotton spinning within at least thirty years or so of its introduction. By the second decade of the nineteenth century, cotton spinning by hand was a redundant occupation.  相似文献
