Since their post-war inception, Sydney's metropolitan plans have tended to be overtaken by the social, economic and environmental conditions they have had to confront. The depth and scope of Sydney's recent urban transformation threatens again to overtake metropolitan planning capacity creating, in the context of competitive globalisation, a potentially significant market disadvantage for the city, not to mention poor urban development outcomes. This paper reviews Sydney's post-war metropolitan planning strategies, examining the social and economic contexts and the policy paradigms in which they have been framed, in order to draw out the lessons to be learned from their successes and failures. We argue that future success in planning urban development will rely on richly informed and fine-grained understanding of the complex spatial outcomes of Sydney's ever-deeper global integration. Only such fine-grained understanding can empower metropolitan planning to be responsive to the evolving challenges of managing development in the contemporary urban context. 相似文献

Archaeological sites are valuable nonrenewable resources and they are being destroyed rapidly by modern development projects
of all kinds, worldwide. The contextual information in these sites could tell surprising and valuable stories of human behavior
over an enormous sweep of time and might contribute to a better future. Archaeologists’ experience of site destruction and
their recent efforts to work with local communities toward alternatives to site destruction may offer examples for others
concerned with the treatment of nonrenewable resources 相似文献

Social science literature suggests that neighborhood-based visual cues have substantive effects on individuals' littering behaviors. Experimental research on this topic typically alters the appearance of a selected public location, and then monitors changes in littering due to these tightly controlled esthetic changes. The general finding is that littering occurs more frequently in relatively disorderly settings. The current paper extends this work by testing whether or not the same finding holds in more “real life” situations, wherein the operative visual cues come directly from the environment rather than through experimental manipulation. Specifically, the paper empirically identifies two study sites that serve similar functions in their urban system, but that differ markedly in contextual features. At the first site (#1), visual cues include liquor stores, vacant structures, and a noisy interstate highway. Notable visual cues at site #2 are scenic vistas, well-maintained housing, and greenspaces. When the same quasi-natural littering experiment was conducted at both locations, the littering rate was significantly higher at site #1 compared to site #2 (after controlling for individual-level demographic attributes). This result adds value to the applied geography community, as it confirms that spatially-based attributes do influence individual behaviors in a manner consistent with controlled, comparatively acontextual experimental findings. Additionally, the results implicate policy strategies that might be useful for counteracting antisocial urban behavior. 相似文献

The paper assesses the role for innovation of one aspect which has been generally overlooked by evolutionary economic geography: context. It analyses how context shapes the impact of collaboration on firm-level innovation for 1604 firms located in the five largest city regions of Norway. Specifically, the analysis shows how the benefits to firms of collaborating within regional, national, and international innovation networks are affected by the knowledge endowments of the region within which the firm is located. Using a logit regression analysis, we find, first, that only national and international networking have a significant positive impact on the likelihood of innovation (the former only for process innovation), whereas the regional knowledge endowments have no direct effect. Second, regional cooperation is particularly effective in regions with high investments in R&D, whereas international cooperation is important in regions with an educated workforce – and regional and national collaboration may be ineffective in such cases. We conclude that, in the case of Norway, context is essential in determining the capacity of firms to set up networks and innovate. Regions with an educated workforce can use the resulting absorptive capacity to successfully assimilate knowledge being diffused through global pipelines from faraway places. However, this absorptive capacity is likely to be heavily filtered if regional firms mainly rely on internal connections within Norway. 相似文献

This paper examines the spatial implications of social-democratic policy transformation. It does so by exploring the political consequences of residential contextual unemployment engendered by a Labour government which had once been dedicated to maintaining full employment. Faced with economic crisis, as Przeworski's model predicts [Capitalism and social democracy, Cambridge University Press, Cambridge (1985)], New Zealand Labour, beginning in 1984, abandoned its traditional social-democratic statist policies, including the maintenance of full employment, and allowed unemployment to skyrocket under its stewardship. This meant subjecting its supporters to significant contextual cross-pressures, since many residential neighbourhoods became characterised by both high concentrations of Labour partisans, and by those recently unemployed by Labour's new market-liberal policies. Using original survey data merged with New Zealand census data, empirical findings show that residual partisan loyalties and a lack of a major party alternative constrained respondents' partisan disaffection, while channelling their disillusionment into both minor party voting and systemic, governmental criticisms - likely fuelling New Zealand's drive for electoral reform and a new system of proportional representation. 相似文献

Expectations about ecosystem based management (EBM) differ due to diverging perspectives about what EBM should be and how it should work. While EBM by its nature requires trade-offs to be made between ecological, economic and social sustainability criteria, the diversity of cross-sectoral perspectives, values, stakes, and the specificity of each individual situation determine the outcome of these trade-offs. The authors strive to raise awareness of the importance of interaction between three stakeholder groups (decision makers, scientists, and other actors) and argue that choosing appropriate degrees of interaction between them in a transparent way can make EBM more effective in terms of the three effectiveness criteria salience, legitimacy, and credibility. This article therefore presents an interaction triangle in which three crucial dimensions of stakeholder interactions are discussed: (A) between decision makers and scientists, who engage in framing to foster salience of scientific input to decision making, (B) between decision makers and other actors, to shape participation processes to foster legitimacy of EBM processes, and (C) between scientists and other actors, who collaborate to foster credibility of knowledge production. Due to the complexity of EBM, there is not one optimal interaction approach; rather, finding the optimal degrees of interaction for each dimension depends on the context in which EBM is implemented, i.e. the EBM objectives, the EBM initiator’s willingness for transparency and interaction, and other context-specific factors, such as resources, trust, and state of knowledge. 相似文献

Power seems to occupy an understated role in much pragmatist thought, both classical and contemporary. It is clearly a blind spot in Richard Rorty’s work, although it is ever present in the background, and for John Dewey and William James it often appears as indistinguishable from the power to act or intervene in events so as to make a difference. In this paper, I want to push a practical account of power a step further by drawing out its expedient, anti-foundational character and its Dewey-style grounding in experience. I also try to show how the power to make a difference may just as easily be transformed into the powers of imposition and constraint, where one side gains at the expense of another. Following that, I draw out a more provisional sense of power based upon the difference that space and spatiality make to what pragmatists have traditionally referred to as the contextuality and contingency of events. This is tentatively explored by a consideration of what spatial experiments with power might look like when employed to bring about change and make a difference in the world. 相似文献
