Much practically orientated environmental research is marked by a polarity between functionalist abstraction and ahistorical normative discourse. This paper seeks to bridge the divide between theoretical and empirical research through a case study of New York City's water supply. Current processes of socio-economic restructuring are leading to negative environmental consequences obscured by a failure to extend analysis beyond limited temporal, spatial or sectoral scales. Insights from regulationist theory show that a combination of fiscal, political and other developments are bringing about a wide-ranging reformulation of existing patterns of environmental regulation and service provision in the city. The power of the state is being radically diminished in relation to the power of capital and a plethora of different interest groups. A relatively simple centralized model of environmental regulation is being transformed into a complex decentralized pattern involving the emergence of new approaches to urban governance. Further research is needed on the contradictions between capitalist accumulation and environmental regulation at different spatial scales in order to link New York's changing role within the global economy to the declining political legitimacy and fiscal capability of the state to play an extensive role in environmental management.  相似文献

青年农民工就业质量问题的实证研究——以长沙市为例   总被引:2,自引:0,他引:2

通过对长沙市301名青年农民工的实证研究表明,青年农民工的就业质量偏低,且受人力资本、社会资本和社会制度的影响显著。要提高青年农民工的就业质量,必须加大青年农民工的人力资本投入,努力扩展青年农民工的社会资本,不断完善现行的社会制度体系。  相似文献

This paper focuses on value creation in electronic waste, and supports the argument (c.f. Herod et al., 2014) that ‘waste’ embodies congealed labour – the product of the labour process. This analysis of itinerant rag-and-bone collectors demonstrates that value creation by informal labour accrues as congealed labour in recycled e-waste through the agentic acts of collecting, salvaging and extracting. This paper highlights the central role of informal labour in this labour process and pushes further the conceptualisation of ‘wasted labour’ (McGrath-Champ et al., 2015) by calling for greater attention to the agentic nature of labour in value creation, rather than simply being a passive means of production. Drawing on Marx's circuit of capital, this paper articulates the central role played by informal labour – an oft overlooked economic actor – in enabling the subsequent recycling processes and conceptualises them as pivotal to the recycling industry.  相似文献

Methodological advancements in geoarchaeology and spatial and chronological modeling are opening new avenues to interpreting large coastal shell-bearing sites. We document the developmental histories of two such sites around Prince Rupert Harbour, Canada, using systematic percussion coring, intensive radiocarbon dating, and 3D surface mapping with Total Station and LiDAR. We also re-analyze a third site (Boardwalk/GbTo-31) excavated and radiocarbon dated in the 1960s, 1970s, and early 2000s using archival field notes, site maps, and stratigraphic profiles georectified using LiDAR. We map the natural landform beneath the sites and document the degree to which people physically modified landforms through the deposition of massive shell accumulations. We model site development through time and space and use accumulation rates and OxCal modeling to test for intentional deposition events. All three sites demonstrate complex and heterogeneous occupation histories. At each we identify instances of very rapid deposition that effectively terraced and extended parts of the natural landform to create places for constructing houses, though these episodes take place within longer histories of slower quotidian deposition. The anthropogenic modifications to the coastline in this area are the result of these mixed processes associated with long histories of occupation.  相似文献

In the great civilisations of the past, shapeshifting promised a restoration of order in turbulent times in return for the deference of loyal subjects. It was a strategy of the powerful to maintain advantage and could also be used to bind opponents to an undesired form. This study finds its resonance in the contemporary shapeshifting that is the supposed transition from the fossil fuel economy. With reference to the fusion of oil, grain and sugar companies in Brazil's ethanol sector, it explores how amidst economic, environmental and political insecurity these “old villains” of the carbon economy have fused and emerged as the “new heroes” of the green economy. Accounts of dissenting rural subjects, however, unveil the mythical nature of avowed social gains from this shapeshifting. Amidst rural conflict and a successive weakening of regulation, it becomes evident how their petrification, in a metaphorical and increasingly literal sense is required.  相似文献

ABSTRACT

Relational networks and intangible factors are crucial elements for the competitiveness of a territory. Public–Private–Partnerships (PPPs), in particular, allow for the provision of goods and services that favour the exploitation of complementarities between public and private resources. They aim at promoting an increase in the overall efficiency of investment projects through a complex mechanism that distributes risk and revenues among stakeholders. This paper examines the local and territorial determinants of PPPs through an econometric analysis based upon Italian municipal data, grouped at the provincial level. Using a tobit model, we analyse the relationship between the realization of successful PPP initiatives and different sets of factors, including less analysed local and territorial determinants. We stress the role of the local management of infrastructure assets, the administrative efficiency of local authorities and the diffusion of previous local development initiatives. Local management and territorial context factors explain most of the occurrence of successful PPP initiatives in the pre-crisis period while usual determinants (infrastructure endowment and financial distress) display a weaker effect.  相似文献

In the 1950s, the Ministry of Health, supported by interested groups outside government, recognised the political importance of productive efficiency. For leadership, organisational models and techniques the Ministry looked to the movement for industrial productivity. The NHS was receptive, but private-sector approaches were modified and dampened as they were imported. NHS management was to be the provider of technical expertise, but the deployment of this expertise was limited by clinical autonomy and de-coupling from financial incentives. This article casts new light on the history of productivity policy, NHS management and the moving frontier between state and civil society.  相似文献
