This paper draws on a study of town twinning in Britain since 1945 to engage with narratives of ‘the new localism’ and ‘the new politics of scale’. It argues that town twinning is often used in technical assistance programmes such as the UK Government's Know How Fund and various schemes of the Commonwealth Local Government Forum. ‘Fast policy’ is a concept that can be usefully applied to these programmes and the broader field of interurban networking, urban policy mobility, and policy transfer. Town twinning plays an active yet overlooked role in fast policy. The paper also argues that town twinning is part of a longer history of bottom-up localism that includes the political arguments of John Stuart Mill, at least two moments of twentieth-century municipal internationalism, the municipal foreign policy movement of the 1980s, and the community development movement of the last three decades. This longer history suggests sources of localism other than statecraft, and problematises the conceptualisation of power and periodisation of history found in regulation theories of devolution.  相似文献

In November 2008, voters in Victoria participated in local government elections under a system that has been subject to significant reform since the 1980s. This paper seeks to discern trends from the outcomes and identify significant structural features of the reformed system. With regards to outcomes, the paper highlights the high success rate amongst incumbent councillors and the strong sense of successful candidates being independent of political parties. The paper argues that these outcomes have been particularly influenced by the proliferation of electoral districts with relatively small voting populations or by the use of multimember electoral systems in larger districts. The variety of systems used underpins a localised and ‘clientelist’ politics that militates against the dominance of political parties over the contest. The paper also draws attention to the comparatively low rate of voter participation in an election in which compulsory voting applies. It argues that voter absenteeism was particularly noticeable in municipalities with large numbers of residents renting properties and might be explained as a form of ‘renters’ illusion’ impacting on voting behaviour.  相似文献

Despite reaching a point of acceptance as a research tool across the geographical and social sciences, there remain significant methodological challenges for agent‐based models. These include recognizing and simulating emergent phenomena, agent representation, construction of behavioral rules, and calibration and validation. While advances in individual‐level data and computing power have opened up new research avenues, they have also brought with them a new set of challenges. This article reviews some of the challenges that the field has faced, the opportunities available to advance the state‐of‐the‐art, and the outlook for the field over the next decade. We argue that although agent‐based models continue to have enormous promise as a means of developing dynamic spatial simulations, the field needs to fully embrace the potential offered by approaches from machine learning to allow us to fully broaden and deepen our understanding of geographical systems.  相似文献

In this study, Monte Carlo (MC) simulations combined with energy dispersive X-ray fluorescence (EDXRF) spectroscopy have been used to characterize non-destructively a collection of Cu-based artifacts recovered from two archeological sites in southern Portugal: (a) the Chalcolithic E.T.A.R. site of Vila Nova de Mil Fontes and (b) the Middle Bronze Age site of Quinta do Estácio 6. The metal artifacts show a multilayered structure made up of three distinct layers: (a) brownish carbonate soil-derived crust, (b) green oxidized corrosion patina, and (c) bulk metal. In order to assess the reliability of the EDXRF-based Monte Carlo simulations to reproduce the composition of the alloy substrate in archeological bronze artifacts without the need to previously remove the superficial corrosion and soil derived patinas, EDXRF analysis together with scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS) was also performed on cleaned and patina-/crust-coated areas of the artifacts. Characterization of the mineralogical composition of the corrosion products in the surface patinas was further determined by means of X-ray diffraction (XRD). Results suggest that the adopted EDXRF/Monte Carlo protocol may represent a safe and fast analytical approach in the quantitative characterization of the bulk chemical composition of Cu-based metal artifacts even in the presence of fairly thick corrosion patinas and/or soil-derived encrustations at the surface of the archeological objects.  相似文献
