This paper addresses the issue of incorporating household dynamics into operational dynamic urban models. Dynamic model approaches that can be used to model urban change are introduced and discussed. We conclude that these different approaches are best combined in an accounting framework. An example of an accounting framework for a dynamic model of Amsterdam is presented. The household submodel is discussed in detail and some preliminary results are given. 相似文献

Foundation deposits underneath the walls of two temples near Semna, Sudan (c. 1500-1480 BC), included dried plant material. Five fruit species are represented: Vitis vinifera (grape), Ficus carica (fig), Citrullus vulgaris (water melon), Phoenix dactylifera (date) and Ziziphus spina-christi. Of particular interest are the remains of tubers of Cyperus esculentus. The plants mentioned above are known as funeral gifts in Egyptian tombs. 相似文献

This study examines the changing roles of heritage professionals by focusing on the participatory practices of intangible urban heritage. Developments towards democratisation in the heritage sector led to a growing expectation that heritage professionals would work with local publics. This democratisation is manifested in (1) the use of digital media for grassroots heritage practices, (2) the broader scope of what is defined as heritage, and (3) a focus on communities in UNESCO’s Convention for the Safeguarding of the Intangible Cultural Heritage. Heritage professionals are thus challenged to develop inclusive heritage practices, particularly in cities, which are characterised by a dynamic nature and cultural diversity. In this article, I analyse how urban heritage organisations and professionals have responded to these developments. Drawing on interviews and a qualitative content analysis of these organisations’ policy documents, I examine the ways in which heritage professionals reconsider their public role through what I define as networked practices of intangible heritage. This concept captures the networked structure in which heritage professionals increasingly work, and also demonstrates how heritage is given meaning through public practices that take place in both the physical and virtual realms of contemporary cities. 相似文献

The managers of a growing wall of money are continuously searching for investment opportunities. The financialization literature describes how this mobile capital puts pressure on commodities, debt, public services and economic activities to transform into investable, tradable, financial products. Regarding real estate, these investigations show how opaque, local, non-standardized goods, highly depending on both local legislation and developments, have been transformed into liquid, globally traded financial assets. By analysing the real estate investment strategies of Dutch institutional investors since the 1980s, this paper shows how a quantitative framework increasingly provides the basis for institutional investors’ real estate investment strategies. Direct ownership of properties has been exchanged into shares of properties, that is, fictitious capital, creating an impetus for ‘objectified numbers’ to measure the performance of these indirect investments. As knowledge about real estate has been outsourced, Dutch institutional investors now perceive real estate increasingly as ‘just another asset class’, thereby increasing leverage and volatility. This paper not only shows how finance ‘financialized’ itself by adopting a quantitative investment perspective, but it also offers an empirical account on how investment properties are transformed into financial assets that put pressure on state agencies to mobilize urban planning to deliver more of such assets. 相似文献
