    Between Speech and Silence: The Postcolonial Critic and the Idea of Emancipation
    Muldoon, P (Taylor and Francis Group, 2001-02-17)
    The concept of emancipation has an increasingly ambivalent status in postcolonial criticism. Under the influence of poststructuralism, the idea that the subaltern subject might overcome colonial relations of cultural domination through acts of self-representation has been thrown into disrepute. If there is to be emancipation, according to this view, it will not come through the recovery of an authentic speaking subject, but through strategies of ‘strategic essentialism’. Here it is argued that this postructuralist approach leaves the subaltern in a politically pre carious position and should be exchanged for the kind of hermeneutic approach that makes possible a genuine politics of recognition.

    The emperor still has no clothes! Genetic determinism as evolutionary psychology
    LAZAROW, MELANIE ; Ferrier, Carole (University Presses, 2002)
    Alas Poor Darwin and It Ain't Necessarily So are excellent tools to help dispel some of the commonly-promoted ideas about genetic determinism that have become so widespread in both academic and popular writing. Evolutionary psychology (EP) has precursors in both sociobiology and eugenics, yet differs from them, pointedly in that sociobiology was never seriously academically accepted while EP is part of the mainstream of academic programs in psychology, biology and anthropology. However it still serves the important ideological purpose of reinforcing sexism, racism and inequality today. EP is needed because, after all, in a society of equal opportunity and social mobility, how is one to explain differences in social power if not by differences in intrinsic ability? Both books show how genetic determinism - although it is poor science - proclaims itself as the legitimate emperor of twenty-first century psychology.

    The effects of obstacles on surface levels and boundary resistance in open channels
    FENTON, JD (AUTh Aristotle University of Thessaloniki, 2003)
    Simple momentum considerations are used to show how the increase in water levels due to obstacles in a natural channel can be calculated. This requires use of a numerical method for solving nonlinear equations, which is not difficult. However it is more insightful to consider an approximate explicit theory, which shows the important quantities governing the problem, and which is accurate enough for practical purposes. It is applicable to obstacles of arbitrary extent and location, in both subcritical and supercritical flow in channels of arbitrary section. A method for the numerical refinement of this is presented, but it will usually not be necessary. The methods are compared with a theory and experimental results for a rectangular channel with vertical cylinders extending the whole depth. Then momentum-loss considerations are applied to explaining the nature of friction laws in open channels. Instead of boundary shear, momentum loss from discrete elements is used as the means of modelling resistance. It is found that the behaviour of Gauckler-Manning's law for wide channels in successfully mimicking the frictional behaviour over a range of depths can be explained, but it does not yet provide a comprehensive theory for general cross-sections.
