There is a wide gap between planning ideology and planning practice in some regimes. In planning practice, contextual differences and traditional practices affect urban spatial configurations and their related societal dimensions, and also influence the legislative and administrative systems that dictate the process and production of the built environment. This is linked to situations where hidden practices and power relations among key actors may limit democratic participation in the planning process and challenge ethical practice. This paper focuses on the emerging traditions of planning practice in Turkey. We argue that by understanding the role(s) of the key actors in the process and investigating approval processes in detail, it can become evident that planning ‘on the ground’ is often tokenistic and circumvented by hegemonic power relations and tactical actions. These latter in turn side-step a requirement for democratic participation and encourage a ‘loosening’ of planning ethics.  相似文献

This essay examines the transnational activities of National Socialist experts, focusing on the endeavours of the burgomaster of Stuttgart, Karl Strölin. In 1938, Strölin became president of the International Federation for Housing and Town Planning (IFHTP), one of the most distinguished international expert institutions for European and North American urban planning. The article discusses his belief that promoting an international convention on the protection of urban populations would contribute to German diplomacy in the initial period of the Second World War. Then it investigates the IFHTP president’s efforts to transform his institution into an outlet for National Socialist ideas against the background of the German advance through Europe. A final section deals with Strölin’s attempts to transform the IFHTP into a forum for evaluating urban reconstruction policies in the last year of the war. This biographical study shows how it was possible to juggle the logics and expectations of seemingly contradictory spatial and political realms during and after World War II. National socialist politics and ideology exacerbated the tensions between local, national and international affiliations, but at the same time never fully permeated the mechanisms of expert internationalism. By revealing how Strölin navigated between local ambitions, the demands of domestic foreign policy and the ethics of expert internationalism in three markedly different projects, this essay contributes to a growing body of scholarship on the cross-border activities of National Socialist professionals in (occupied) Europe.  相似文献

Visualisations of land-use projects have become an important part of the planning process. Using a survey of heritage professionals’ attitudes towards visualisations as a starting point, this article addresses tensions between the expressed usefulness of visualisations and critical attitudes towards the lack of ‘objectivity’ of visual representation and the risk of manipulation for strategic purposes. Moving from the survey, the article discusses how visual representations of development proposals became part of a Norwegian public dispute over the expansion of a shopping centre in a historic town. Furthermore, our aim is to introduce a social semiotic approach for analysing visualisations at historic sites. Finally, we discuss some theoretical implications of negotiating visualisations, with emphasis on the recent debate about representational and non-representational theories in heritage studies.  相似文献

This article argues that warfare has been marginalised in theories of nationalism but that in conjunction with nationalism is vital for understanding the rise of nation‐states, the formation of nations and the nature of the international system. It offers a critique of statist approaches, suggests mechanisms through which warfare may sacralise nations and explores different patterns of nation‐state formation as they affect the interstate system. In particular, it emphasises tensions between state and nation‐formation as activated by the fortunes of war and the destabilising effects of waves of imperial dissolution, which are accompanied by patterns of re‐imperialization. It suggests that it is simplistic both to claim that war has led to a transition from empires to nation‐states and that contemporary practices of war‐making have led to a postnational era.  相似文献

手机信令数据所代表的人流联系与国内外研究常用的企业关联数据在测度城市关联存在何种差异,尚缺乏明确的研究。本文以江西省北部地区为研究对象,分别以手机信令数据、企业关联数据测度城市关联,比较了两种城市关联与城市之间空间距离、人口规模的关系,比较了两种城市关联网络的层级、结构、腹地。主要研究发现:人流联系不仅集中在城市周边地区,而且集中于较高等级城市之间;经济联系则主要集中在较高等级城市之间。人流联系、经济联系受到城市人口规模影响均较小。人流联系显著地符合幂函数空间衰减规律。手机信令数据和企业关联数据是两种不同的城市关联数据,但可互为补充,较为全面地反映城市关联。  相似文献

Intensive farming is an increasing part of Australian agriculture, including in the multi‐functional landscapes at the edges of Australian cities. The example of intensive “broiler” poultry production reveals the tensions that arise when sites of hyper‐productivity conflict with social change in rural areas. Planning processes for intensive farming in the Australian state of Victoria are predicated on stability and consensus: on assumed static and uncontroversial ideas of agriculture, its place, and the primacy of agricultural productivity. Yet concerns about the industrialisation of agriculture are live political issues at the local level, especially in dynamic peri‐urban locations. This paper explores the emergence of a politics of place outside the bounds of planning consensus through an analysis of planning appeals and associated media relating to planning permits for intensive poultry developments in Victoria over 2011–2016. We highlight tensions that exist in relation to technical planning assessments and categorisations used to assert farming as the orthodox use of rural land, especially when new forms of farming look and feel demonstrably different. Using Mouffe's problematising of the negation of antagonism and Rancière's notion of the risks of a false consensus democracy, we argue that planning processes for intensive farming illustrate critical issues in participatory planning. While ostensibly post‐political decision‐making narrows the politics of place and food systems to decisions about policing the boundaries and buffer distances placed around intensive poultry developments, alternative representations of rural life persist. The certainty offered by code‐based planning does not negate the ongoing (if inconvenient) politics of intensive peri‐urban agriculture.  相似文献

Accurate simulation of multiphase flow in fractured porous media remains a challenge. An important problem is the representation of the discontinuous or near discontinuous behaviour of saturation in real geological formations. In the classical continuum approach, a refined mesh is required at the interface between fracture and porous media to capture the steep gradients in saturation and saturation‐dependent transport properties. This dramatically increases the computational load when large numbers of fractures are present in the numerical model. A discontinuous finite element method is reported here to model flow in fractured porous media. The governing multiphase porous media flow equations are solved in the adaptive mesh computational fluid dynamics code IC‐FERST on unstructured meshes. The method is based on a mixed control volume – discontinuous finite element formulation. This is combined with the PN+1DG‐PNDG element pair, which has discontinuous (order N+1) representation for velocity and discontinuous (order N) representation for pressure. A number of test cases are used to evaluate the method's ability to model fracture flow. The first is used to verify the performance of the element pair on structured and unstructured meshes of different resolution. Multiphase flow is then modelled in a range of idealised and simple fracture patterns. Solutions with sharp saturation fronts and computational economy in terms of mesh size are illustrated.  相似文献

The criminal justice system is increasingly becoming the subject of national dialogue throughout the United States due to the sheer number of people it impacts: according to the Department of Justice, nearly 7 million, or 1 in 35, U.S. residents are under some form of correctional control. The four books reviewed in this essay derive their findings from ethnographic methods that offer deep insights into the carceral state’s everyday operations in individual women’s lives, while raising profound theoretical and practical questions about gender and governance. We engage with these texts from unique situated standpoints as insider-outsiders with intimate knowledge of the U.S. criminal justice system gleaned from our respective lived experiences, services provision work, and research with currently and formerly incarcerated Wyoming women.  相似文献
