As green infrastructure (GI) plans are being developed and implemented in a number of regions throughout the UK and interest in the theory and methods is emerging in various other countries there is opportunity to explore the potentials for GI planning throughout Europe. Using the experience of the UK, and particularly that of stakeholders and organizations in the North East of England, we analyse the functions and benefits that a GI network can provide and, through cross-national comparison, we critically theorize the potentials for GI planning in Catalonia. While recognizing that there are key differences between these regions, particularly in relation to climate, societal characteristics, institutional organizations and frameworks for landscape planning, we discuss the transferability of the characteristics which appear to be provided from GI planning in the UK. We conclude that, overall, the implementation of GI planning would be relatively easy to achieve and mostly beneficial under a Mediterranean environment. Our conclusions are tempered by a recognition that the provision of functions and benefits are subject to the influence of the particular organizational characteristics and the cultural background of each region, and in particular the different impacts that climate change is likely to have.  相似文献

This article is about the question of social agency in the animation of things , and about how this problematic has been conceptualized in Marxist and Actor-Network Theory (ANT) approaches to human–nature–technology relations. Notwithstanding many obvious differences, we note that each tradition was founded on a radical shift to a relational ontology, a world of relations and processes and not things-in-themselves, and that each has developed, partly as a consequence of this move, analytically useful ways of investigating and talking about the work that things do, or appear to do, in the world. By relating the ANT category of non-human actors to the Marxist concept of dead labor, and by revisiting Marx's own dialectics of technology as embodied in his figure of the "living machine" in Capital , we explore the different implications of these approaches for our understandings of the nature, materiality, and the efficacy of social agents. We argue that ANT's reconfiguration of agency as a collective social and technical process—a process wherein the "nonhuman" can have very real social effects—can be deepened and given some political efficacy only if we take seriously the ontological problems of causality, accountability, and the directedness of social relations (and things) which ANT, and its wider, still evolving ethos among the social sciences and cultural studies, would have us forestall.  相似文献

This paper is an analysis of monetary circulation in early medieval Italy in the period c.600–900. Using a dual comparison – first, of the level of currency use as against ceramics within Italy, and second, of the pattern of Italian coin use, and economic activity more generally, with that north of the Alps – this paper presents examples that shed light on patterns of change and discontinuity.  相似文献

The paper provides some empirical evidence of the effectiveness of the “open innovation” model in the life science cluster of Emilia Romagna (a region of Italy), comparing the network of R&D collaborative activities in public research organizations (PROs) and the network linked to R&D collaborative activities in private firms. By presenting the main results of a field research in the life science sector in Emilia Romagna, we are contributing to the recent debate focused on the crises of the old “closed innovation” model and the rise of the “open innovation” model. Our survey consists of both primary data deriving from face-to-face interviews with researchers and entrepreneurs, and secondary data extracted from the Internet, the PubMed database, and from the European Patent Office. Our work is based on the analysis of a representative sample of 30 research groups in PROs, 2173 scientific articles published by the interviewed scientists, and a representative sample of 78 private firms.  相似文献
