The article focuses on the redevelopment of previously developed land by public-private sector partnerships in three cities/towns in South-West England, two of which can be described as medium-sized places with little previous experience of such developments. In each case we situated the redevelopment process in its wider multi-level and horizontal relationships using Social Network Analysis to produce network and centrality maps to reveal the complex network of relationships the process was embedded within and shaped by. These developments took place in what is termed the ‘roll-out’ phase of neoliberalism and we illustrate how the overarching planning and regulatory regimes (including contracts), along with wider economic conditions, shaped the development process, with the proviso that in each case these factors were mediated and themselves shaped by the assortment and interaction of local organizational, political, economic and civic forces. These included local planning committees and their interpretation of planning regulations and the developers involved, but also opposition to the developments from local sources. Much, however, depended on the ‘capacity to act’ of the relevant partnerships, in the sense of mobilizing and deploying available resources to realize the proposed developments.  相似文献

The seismic response of a continuous 4-span bridge designed according to the current Canadian seismic provisions is investigated using Incremental Dynamic Analysis (IDA). Different earthquake types, including shallow crustal events, interface Cascadia subduction, and deep inslab subduction are considered. The median collapse capacities calculated using different record selection methods including Conditional Mean Spectrum (CMS)-based, Uniform Hazard Spectrum (UHS)-based, and epsilon-based methods are compared. The use of the epsilon-based method generally resulted in the highest collapse capacity predictions, but the CMS-based method was less sensitive to the number of records considered in the IDA.  相似文献

The relations between riverbank erosion and geomorphological variables that are thought to control or influence erosion are commonly modelled using regression. For a given river, a single regression model might befitted to data on erosion and its geomorphological controls obtained along the river's length. However, it is likely that the influence of some variables may vary with geographical location (i.e., distance upstream). For this reason, the spatially stationary regression model should be replaced with a non‐stationary equivalent. Geographically weighted regression (GWR) is a suitable choice. In this paper, GWR is extended to predict the binary presence or absence of erosion via the logistic model. This extended model was applied to data obtained from historical archives and a spatially intensive field survey of a length of 42 km of the Afon Dyfi in West Wales. The model parameters and the residual deviance of the model varied greatly with distance upstream. The practical implication of the result is that different management practices should be implemented at different locations along the river. Thus, the approach presented allowed inference of spatially varying management practice as a consequence of spatially varying geomorphological process.  相似文献

Some radiocarbon dates for ancient Egypt have been significantly offset from the established historical chronology (see Bonani et al., 2001). In this paper, short-lived plant species collected in Egypt between 1700 and 1900 AD were used to investigate the possibility that the radiocarbon record had been influenced by reservoir effects. AMS radiocarbon measurements were made on 66 known-age samples, resulting in an average offset from expected values of 19 years. The implications of this minor discrepancy on the likelihood of a reservoir process are discussed, and the agreement of the data with recent models of radiocarbon seasonality is also considered.  相似文献

Abstract

Politics and religion often use the same kind of language to achieve their ‘missionary’ ends, hut such language is stripped of its meaning unless it is related to ultimate, rather than short-term, purpose. This is demonstrated by notions of election, the place of the prophet and the effects of the ‘powers’ in global society. The energy and creativity of responding to an ultimate vision is undermined in both political and relgious affairs by institutionalization. The fact that this takes place asks us to reconsider what it really means, in both religion and politics, to ‘reach out to people’ and what purpose such outreach serves.  相似文献

This article explores the phenomena of geographical imaginations and their seldom-noted promotion within various corners of Fascist Italy. Imagined geographies are socially constructed understandings of other places and regions and, as such, they are malleable, contingent, shifting and unquantifiable. Nevertheless, these imaginaries help us to navigate our imaginative worlds and our relative place in the material world. In 1930s Italy, various interest groups associated with the colonial and expansionist projects of Fascism promoted the development of wider geographical imaginaries among Italians. Academic geographers were often key figures in these initiatives: some prompted these projects, while others did so at the behest of the regime and its desire to expand Italians' coscienza geografica (the geographical imagination) to an ‘imperial level’. This article explores how academic geographers from Trieste sought to contribute to this project and to embed their geographical knowledge into the ordinary, everyday circuits of public life. The article therefore outlines the notion of the geographical imagination and demonstrates via case studies how Triestine geographers tried to nurture these phenomena. Finally, it suggests that, although elusive and amorphous, geographical imaginations were a feature of everyday life in some corners of Fascist Italy and, as such, they deserve academic attention.  相似文献
