Why Unfree Labour is Not ‘So-Called’: The Fictions of Jairus Banaji

In a recent critique of the deproletarianization thesis, which links the reproduction of unfree labour mainly - but not only - in Third World agriculture to class struggle prosecuted by capitalist producers, Banaji maintains in effect that there is no such thing as unfree labour. Equating the latter with nineteenth-century liberal ideas about freedom as consent, he conceptualizes all historical working arrangements simply as ‘disguised’ wage-labour that is free, a theoretically problematic claim first made during the Indian mode of production debate. Such a view, it is argued here, ignores the fact that unfree workers get paid and also appear in the labour market, but not as sellers of their own commodity. Moreover, by abolishing the free/unfree labour distinction, and adopting instead the view that all rural workers are simply ‘disguised’ hired labourers who are contractually ‘free’, Banaji aligns himself with anti-Marxist theory in general, and neoclassical economic historiography in particular.     

How reliable is the sub-population model in DNA testimony?

The performance of the sub-population model first proposed by Balding and Nichols [D.J. Balding, R.A. Nichols, DNA profile match probability calculation: how to allow for population stratification, relatedness, database selection and single bands. Forensic Sci. Int. 64 (1994) 125-140] is examined using a simulation approach. This work extends the investigations of Curran et al. [J.M. Curran, J.S. Buckleton, and C.M. Triggs, What is the magnitude of the sub-population effect? Forensic Sci. Int. 135 (2003) 1-8]. In particular the effect of underestimating the coancestry coefficient, theta, and the effect of departures from the modelling assumptions were investigated. The model tends to give strongly conservative estimates if the estimate for the coancestry coefficient is accurate. If this coefficient is underestimated then a larger fraction of cases give non-conservative estimates. Departures from the modelling assumption that the sub-population is in Hardy-Weinberg and linkage equilibria appear to have very little effect.
