In the Name of Merit: Ethical Violence and Inequality at a Business School

Abstract: This study examines how meritocracy as a collective social imaginary promoting social justice and fairness reproduces class and caste inequalities and fosters ethical violence. We interrogate discourse of merit in the narratives of the professional–managerial class-in-making at an Indian business school. Empirically, we draw on interviews, full-text responses to a qualitative questionnaire, and a student’s poem. We describe how business school students articulate merit as a neoliberal ethic, emphasizing prudential, enterprising attitudes, and responsibility. However, this positive, aspirational facade of merit masks practices of ethical violence, wherein individuals invoke an ethical principle as grounds for moral condemnation and linguistic injuries. These practices of ethical violence desubjectify disadvantaged students and result in silence as a form of inequality. We contribute to organizational research on inequalities by foregrounding ethical violence and desubjectification. We detail the possibilities of discursive agency in contesting and interrupting ethical violence.

Highly Efficient Factorial Designs for cDNA Microarray Experiments: Use of Approximate Theory Together with a Step-up Step-down Procedure

Abstract: A general method for obtaining highly efficient factorial designs of relatively small sizes is developed for cDNA microarray experiments. The method allows the main effects and interactions of successive orders to be of possibly unequal importance. First, the approximate theory is em-ployed to get an optimal design measure which is then discretized. It is, however, observed that a naive discretization may fail to yield an exact design of the stipulated size and, even when it yields such an exact design, there is often scope for improvement in efficiency. To address these issues, we propose a step-up/down procedure which is seen to work very well. The resulting highly efficient designs are found to remain almost free from possible dye-color effects under a suitable dye-color assignment. They are also seen to be quite robust to heteroscedasticity as may be caused by biological variability. We focus on the baseline and all-to-next parametrizations but our method works equally well also for hybrids of the two and other parametrizations.
