    Transport in a sustainable urban future

    Transport is acknowledged as a vital ingredient of any credible strategy for the sustainable city because of the key role it plays in promoting economic development, quality of life and wellbeing. Yet managing urban transport effectively, given its complex and intersecting economic, environmental and social impacts, is also precisely the kind of ‘wicked problem’ that policy makers consistently find hard to resolve (Docherty and Shaw, 2011a; Conklin, 2006; Rittel and Webber, 1973). Many of the reasons for this are longstanding and emanate in particular from the dominance of the private car in meeting the demand for mobility, which has built up over many decades in the developed world, but which is now being reproduced at a much higher pace in the fast growing cities of the Pacific Rim and elsewhere (Newman and Kenworthy, 1999; Lyons and Loo, 2008). Although it has undoubtedly transformed our patterns of travel and consumption, concerns over the limitations and externalities of private car transport – primarily traffic congestion, environmental degradation and social exclusion – have for many years stimulated various initiatives designed to mitigate these externalities (Feitelson and Verhoef, 2001; Knowles et al, 2008). The conflict between the car, long promoted by neoliberal voices as a potent weapon of the free market and individual liberty, and competing visions of a more ‘public’ transport system based on collective modes such as the bus and train, and active travel by walking and cycling, has been played out over many years. Nowhere has this conflict been more intense than in cities, as it is here that the problems such as congestion, poor local air quality and mobility deprivation are often at their most intense (Cahill, 2010; Docherty et al, 2008)

    A disintegrating cosmic string

    Get PDF
    We present a simple sandwich gravitational wave of the Robinson-Trautman family. This is interpreted as representing a shock wave with a spherical wavefront which propagates into a Minkowski background minus a wedge. (i.e. the background contains a cosmic string.) The deficit angle (the tension) of the string decreases through the gravitational wave, which then ceases. This leaves an expanding spherical region of Minkowski space behind it. The decay of the cosmic string over a finite interval of retarded time may be considered to generate the gravitational wave.Comment: 3 pages, 1 figure, to appear in Class. Quantum Gra

    Transport strategy in Scotland since devolution

    Get PDF
    This article critically reviews how the Scottish Executive's approach to transport has developed since devolution. Although there is much to commend, a number of concerns can be identified, including the possibility that a number of strategic infrastructure schemes appear to have been approved on political rather than on technical grounds. It is difficult to know whether the current set of transport infrastructure investment plans represents good value for public money

    Devolution as process: institutional structures, state personnel and transport policy in the United Kingdom

    Get PDF
    Devolution has been described as a key ‘global trend’ over recent decades as governments have decentralised power and responsibilities to subordinate regional institutions (Rodriguez-Pose and Gill, 2003). UK devolution is characterised by its asymmetrical nature with different territories granted different institutional arrangements and powers. In this paper, we seek examine the role of state personnel in mobilising the new institutional machinery and managing the process of devolution, focusing on transport policy. Our research shows a clear contrast between London and Northern Ireland, on the one hand, and Scotland and Wales, on the other, in terms of the effectiveness of political leaders in creating clear policy priorities and momentum in transport

    Characterisation of unsteady turbulence in breaking tidal bores including the effects of bed roughness

    Get PDF
    A tidal bore is an unsteady flow motion generated by the rapid water level rise at the river mouth during the early flood tide. With time, the leading edge of the tidal wave becomes steeper and steeper until it forms a wall of water that is the tidal bore. Herein the turbulence in breaking tidal bores was investigated experimentally under controlled conditions with two types of bed roughness: smooth PVC and fixed gravel bed (ks = 3.4 mm). Some qualitative observations were conducted with both undular and breaking bores. The tidal bore flow patterns were independent of the bed roughness, as well as of the initial steady flow conditions, while the free-surface properties were close to earlier findings. Using an ensemble-averaging technique, the free-surface fluctuations of breaking bores were characterised. Immediately prior to the roller, the free-surface curved gradually upwards and the gentle surface elevation rise was about 0.1×do where do is the initial water depth. The passage of the bore roller was associated with some large water depth fluctuations. Some detailed turbulent velocity measurements were performed at several vertical elevations during and shortly after the breaking bore passage. Both the instantaneous and ensemble-averaged velocity data highlighted some seminal features of breaking bores. Namely a strong flow deceleration was observed at all elevations during the tidal bore passage. Close to the bed, the longitudinal velocity component became negative immediately after the roller passage implying the existence of a transient recirculation "bubble". The vertical velocity data presented some positive, upward motion during the bore front passage with increasing maximum vertical velocity with increasing distance from the bed. The vertical motion was believed to be linked with some streamline curvature. The transverse velocity data presented some large fluctuations with a non-zero ensemble-average after the roller passage that highlighted some intense secondary motion advected behind the bore front. A comparison between ensemble-average (EA) and variable interval time average (VITA) velocity data was performed. The EA and VITA results showed some comparable velocity pattern with some relatively-long-term data trend superposed to some high-frequency turbulent fluctuations. The data showed however that the VITA calculations for a single experiment presented some non-negligible difference with the EA median value for all velocity components. Overall the study demonstrated the intensive turbulence and turbulent mixing under a breaking tidal bore

    Improving child protection : a systematic review of training and procedural interventions

    Get PDF
    Aim: To synthesise published evidence regarding the effectiveness of training and procedural interventions aimed at improving the identification and management of child abuse and neglect by health professionals. Methods: Systematic review for the period 1994 to 2005 of studies that evaluated child protection training and procedural interventions. Main outcome measures were learning achievement, attitudinal change, and clinical behaviour. Results: Seven papers that examined the effectiveness of procedural interventions and 15 papers that evaluated training programmes met the inclusion criteria. Critical appraisal showed that evaluation of interventions was on the whole poor. It was found that certain procedural interventions (such as the use of checklists and structured forms) can result in improved recording of important clinical information and may also alert clinical staff to the possibility of abuse. While a variety of innovative training programmes were identified, there was an absence of rigorous evaluation of their impact. However a small number of onegroup pre- and post-studies suggest improvements in a range of attitudes necessary for successful engagement in the child protection process. Conclusion: Current evidence supports the use of procedural changes that improve the documentation of suspected child maltreatment and that enhance professional awareness. The lack of an evidence based approach to the implementation of child protection training may restrict the ability of all health professionals to fulfil their role in the child protection process. Formal evaluation of a variety of models for the delivery of this training is urgently needed with subsequent dissemination of results that highlight those found to be most effective

    The 2007 Provincial Election and Electoral System Referendum in Ontario

    Get PDF
    Ontario’s general election in Oct. 10, 2007, was unprecedented for several reasons. The election was held on a date fixed by legislation and not one set by the premier or his caucus, something new to Ontario and relatively new to Canadian politics. Turnout declined to 53%, the lowest ever in Ontario history. The incumbent Liberals won a second consecutive majority government, something the party had not achieved since 1937. And finally, the election featured a referendum question that asked voters in Ontario to approve reforms to the electoral system, a proposal that was overwhelmingly rejected. This article explores each of the above-stated elements as they unfolded in the election
