    African Studies Seminar series. Paper presented March 1986During the afternoon of 17 June 1929, 6 000 African workers abandoned their barracks, backyard dwellings, rented rooms and kias, and made their way through the streets of Durban towards the Industrial and Commercial Workers' Union (ICU) Hall in Prince Edward Street. The more noticeable amongst the ranks of stickwielding workers included the barefoot dock workers, domestic servants in redtrimmed calico uniforms and ricksha-pullers displaying colourful tunics. The less noticeable comprised the majority - the labouring poor of the port town. The immediate reason for this mass mobilisation was the 'siege', by 600 white 'vigilantes', of the ICU Hall. Having beaten one African to death with pickhandles, the vigilantes comprising the 'well-educated', 'the elderly' and a 'large hooligan element1 attempted to storm the Hall. They mistakenly believed that two white 'traitors' - Communist Town Councillor S.M. Pettersen and A.F. Batty, an ICU organiser - were ensconced inside. When the "relief column" of workers finally reached the Hall they were greeted by 2 000 whites and 360 policemen. The violent clashes which followed left 120 injured and 8 dead. The riots of June 1929 in Durban occupy a brief moment within a wider process of sustained urban militancy. This popular opposition was an expression of both a particularly repressive and exploitative system of urban control and impoverishment in Natal's countryside during a period of economic depression spanning the years 1928 to 1933

    AFM imaging and plasmonic detection of organic thin-films deposited on nanoantenna arrays

    In this study, atomic force microscopy (AFM) imaging has been used to reveal the preferential deposition of organic thin-films on patterned nanoantenna array surfaces - identifying the localised formation of both monolayer and multilayer films of octadecanethiol (ODT) molecules, depending on the concentration of the solutions used. Reliable identification of this selective deposition process has been demonstrated for the first time, to our knowledge. Organic thin-films, in particular films of ODT molecules, were deposited on plasmonic resonator surfaces through a chemi-sorption process - using different solution concentrations and immersion times. The nanoantennas based on gold asymmetric-split ring resonator (A-SRR) geometries were fabricated on zinc selenide (ZnSe) substrates using electron-beam lithography and the lift-off technique. Use of the plasmonic resonant-coupling technique has enabled the detection of ODT molecules deposited from a dilute, micromolar (1 M) solution concentration - with attomole sensitivity of deposited material per A-SRR – a value that is three orders of magnitude lower in concentration than previously reported. Additionally, on resonance, the amplitude of the molecular vibrational resonance peaks is typically an order of magnitude larger than that for the non-resonant coupling. Fourier-transform infrared (FTIR) spectroscopy shows molecule specific spectral responses – with magnitudes corresponding to the different film thicknesses deposited on the resonator surfaces. The experimental results are supported by numerical simulation

    A new characterization of Talagrand's transport-entropy inequalities and applications

    Full text link
    We show that Talagrand's transport inequality is equivalent to a restricted logarithmic Sobolev inequality. This result clarifies the links between these two important functional inequalities. As an application, we give the first proof of the fact that Talagrand's inequality is stable under bounded perturbations.Comment: Published in at http://dx.doi.org/10.1214/10-AOP570 the Annals of Probability (http://www.imstat.org/aop/) by the Institute of Mathematical Statistics (http://www.imstat.org

    The struggle for the city : alcohol, the ematsheni and popular culture in Durban, 1902-1936

    Bibliography: pages 337-373.This thesis concerns itself with the genesis and development of the Durban system but also provides a point of entry into the social history of Durban. There are a number of threads which hold this study together. The most central of these comprises an examination of those struggles between ordinary African people and the white rulers of the town over access to, and the production of drink generally, and utshwala in particular. The lengths to which the state in South Africa has gone in order to control the supply of alcohol, particularly utshwala, to African popular classes and the intensity of the resistance to this control has, with one notable exception, been largely ignored by historians. This neglect is understandable. Not only is the study of the making of South Africa's working classes in its infancy but regional social histories have only recently begun to make their appearance in written form. Moreover, research has tended to focus on the Transvaal, especially the Witwatersrand, and the main concern of such studies has been to concentrate on the regional with a view to arriving at more general conclusions about the state and the nature of class formation and consciousness. In their sensitivity to local-level and regional concerns, these studies are invaluable and certainly they represent an important step away from, as Tim Keegan has noted, the growing sterility of the debates on race and class, on segregationist ideology and practice, and on the nature and role of the state

    Impacts of fuel consumption taxes on mobility patterns and CO2 emissions using a system dynamic approach

    Full text link
    Current transport behaviour leads to increasing congestion of the infrastructure, growing dependence on fossil fuels, increasing energy demand, and growing CO2 emissions. Policies based principally on increasing system speed and in particular car speeds will lead to greater urban sprawl with increases in average trip lengths. Time saved by speed increases are traded for more distance. This trend is not sustainable in the longer term. Transport policies based just on time savings for citizens may not be the basis for our city planning strategy. The same happens with transport cost. With underpriced transport, the market undervalues land use location, which again may lead city to sprawl and could induce greater trip lengths. In this study, the efficiency of a fuel consumption or CO2 tax policy is analysed as a policy to internalise externalities of transport in a fair travel cost. Based on system dynamics theory, an integrated land use and transport model is proposed in order to assess the effects and impacts of such policy in the short, medium and long term. Different scenarios related to clean vehicles are incorporated. This model is applied to three cities Madrid, Vienna and Leeds and compares their results
