Area-based policies for crime prevention     

David T. Herbert  Keith D. Harries 《Applied geography (Sevenoaks, England)》1986,6(4)

The new emphasis upon crime prevention which has appeared in recent years has led to realignments in policing policy in both the United Kingdom and the United States. Although by no means leading to the abandonment of the more traditional forms of policing, schemes such as Neighbourhood Watch and the wider concept of community policing involve far greater levels of interaction between the police and the public. Area-based policies have appeared in numerous forms and have proved convenient ways for crime control resources to be organized. Early experiments in policing practice have not produced clear answers on the effectiveness of various strategies and there are wider issues of crime identification and control to be considered. A number of schemes of different kinds, ranging from target-hardening projects which increase physical security in particular areas, to attempts to involve communities in more effective social control are reviewed, and it is argued that the established methodologies of urban geography have much to offer in the monitoring and evaluation of crime prevention schemes of this kind.  相似文献

Cultural policy and place promotion: Swansea and Dylan Thomas     

Helen Watkins  David Herbert 《Geoforum》2003,34(2):249-266

As former industrial cities have experienced radical changes to the bases of their economies, the imperatives of finding new roles and functions has often led to the adoption of cultural policies. These are diverse and partial but have become part of place promotion policies designed to attract visitors and investors. The connection with a literary figure offers one exploitable quality and this paper explores the adoption of Dylan Thomas, poet and writer, as an icon for Swansea. What emerges is the existence of a diversity of interested individuals and groups, who start from different positions but work towards a common goal. The tensions about the life and works of the poet, evident over the 50 years since his death are still there but the key players, including the City and County of Swansea, are finding ways of reconciling their differences in the ‘production’ of Dylan Thomas. This use of a writer and his local connections forms part of the more general process of making a cultural policy for the city.  相似文献

Two-feldspar geothermometry: a review and revision for slowly cooled rocks   总被引：13，自引：0，他引：13

Recent improvements in the experimental and thermodynamic basis of two-feldspar geothermometry allow one to recover temperatures of coexistence more reliably. Some problems, however, persist: (1) the experimental solvi by Seck (1971a) and Elkins and Grove (1990) differ from each other; (2) it is not known to what extent Na–K–Ca exchange equilibrium is approached; (3) both solvi are probably metastable with regard to Al, Si order; (4) it is difficult to judge how closely high-temperature natural feldspars compare to this situation; (5) the thermodynamic treatment neglects phase transformations; (6) the temperature dependence of the Margules parameters used to model non-ideal mixing behaviour may not be linear; (7) it is not clear which expressions should be used to describe ideal activities. With these caveats in mind we treat the problem of retrograde resetting in high-grade metamorphic rocks that were slowly cooled under essentially dry conditions. Coexisting feldspars from such rocks commonly do not plot on a common isotherm. Thus temperatures derived from such pairs using any of the proposed two-feldspar geothermometers will necessarily be in error. We suggest that the non-equilibrium compositions result from retrograde intercrystalline K–Na exchange. This exchange continues after the plagioclase and alkali feldspar have already become essentially closed systems with respect to Al–Si exchange, which is a prerequisite for (Na,K)–Ca exchange. We use a modified version of the Fuhrman and Lindsley (1988) programme to reverse the K–Na exchange and derive concordant temperatures.  相似文献

APu heat source in marine coastal sediment: formation of a protective concretion     

Herbert V. Weiss  Dan Pavone 《Applied Geochemistry》1986,1(6)

The effect of the marine environment upon a vented Ir-encapsulated²³⁸Pu heat source was investigated. The heat source was emplaced in coastal submarine feldspathic sediment. In less than a month it became encased in a rock-like concretion. The capsule was cemented initially with a white deposit of anhydrite, a mineral identified with high temperature deep-sea springs. As the concentration increased in thickness sedimentary particles were incorporated by the cementing agent. A non-porous barrier was formed such that decay product He was impeded from escape. This property protected the heat source against intrusion by the corrosive marine waters.As determined by neutron activation, the major and minor elements within the coastal sediment, various fractions of the concretion, and certain discrete entities within or on the surface of the concretion, are included.  相似文献
