Children with special educational needs (SEN) are more likely to experience victimisation at school and there is some evidence to suggest that these children are also more likely to engage in bullying behaviours; however, no measure of bullying experiences has been designed specifically for use with these children. The Bullying Behaviour and Experiences Scale (BBES) was specifically developed a...

Simple heteroscedasticity is discussed in detail by Sen (1984), Sen & Ponnuswamy (1991) and Rahaman and Sen (1995). In this paper, heteroscedasticity is considered in a RBD assuming error variances vary from cell to cell. There are more than one observations per cell in this layout. The twoway general heteroscedastic model is considered here with interaction. On the assumption that the unequal ...

In the framework of ethical social choice theory, sustainability is justified by Efficiency and Equity as ethical axioms. These axioms correspond to the Suppes-Sen Grading principle. In technologies that are productive in a certain sense, the set of Suppes-Sen maximal utility paths is shown to equal the set of non-decreasing and efficient paths. Since any such path is sustainable, Efficiency an...
