Previous research efforts demonstrate the use of location covering in the spatial structuring of central places within a single-good context. In a multilevel context, this paper similarly develops a mathematical programming approach to the siting of central places based on the “protection” of inner (or threshold) markets. The objective function maximizes both market coverage of demand and market overlap, subject to an upper bound on market overlap; this allows the formation of different market structures consistent with the various K-valued central place systems of Christaller and Lösch. Siting examples serve to illustrate the working of the protected threshold model in isotropic settings. Furthermore, ways in which the present model might be extended for other situations are examined. 相似文献

This article draws on examples of inventive plastic reuse from India and personal anecdotes of elders as an anthropological reflection on possible plastic futures. It sketches the large-scale governmental reforms in the domain of municipal solid waste management, or MSWM (which, by legal definition in India, includes plastic waste). In this regard, it draws out some of the problematic socio-political and environmental implications of Prime Minister Narendra Modi's ‘Clean India’ campaign, whose technocratic policy orientations towards standardized centralized MSWM echo his cultural nationalist agenda. These reforms contrast with home-based re-engineering methods and the redeploying of plastic discards (thereby making them notuner moton (‘like new again’), and their localized circulation through relatively local but uneven reputational and economic networks. Clean India sequesters and processes vast quantities of plastics through the wide-ranging adoption of a waste-to-energy techno-fix (in which plastics are incinerated). In contrast, the authors illustrate routine practices and relations whereby people reuse, repurpose and recycle plastics. While Clean India can detract from and disrupt these mundane practices and everyday relations, these are suggestive of alternative plastic futures – both socio-material and environmental. 相似文献

This paper draws on a multimethod ethnographic study, conducted between 2016 and 2017 in Shirebrook, Derbyshire, England—a small and relatively isolated deindustrialising colliery town—examining how residents negotiate living in stigmatised territory. In doing so, microspatial strategies of distancing, avoidance, and deflection are illustrated, revealing how residents reassign and deepen stigma in particular locations within a stigmatised territory. This highlights the relationship between social and physical space, and while spatial strategies of negotiation do not mitigate stigma, they do (re)produce internal social hierarchies within a place that is homogenised from the outside through disparaging narratives. A key contribution reveals the significance of the racialised production of space in shaping how territorial stigma is negotiated within this distinct socio-spatial location. Residents use strategies to redirect the stigma toward those seen as out of place and draw attention away from sticky sites of racialised urban stigma towards symbols of unspoilt rural Englishness. 相似文献
