Factorisation properties of the strong product

We investigate a number of factorisation conditions in the frame- work of sets of probability measures, or coherent lower previsions, with finite referential spaces. We show that the so-called strong product constitutes one way to combine a number of marginal coherent lower previsions into an independent joint lower prevision, and we prove that under some conditions it is the only independent product that satisfies the factorisation conditions

The arts and staying cool.

Art can be messy. Teaching art can be messy. Teaching can be a messy process. The art of making a space for the playfulness and messiness of teaching requires courage and letting go. This paper develops the verandah metaphor for re-thinking the place of the arts in education, in order to make space for some of the institutionalised ambivalence in arts education. Four sites of practice are examined, where contingencies come into play, and where current practices act to both enable and constrain our ways of working with young children. The paper concludes with some new (messy) possibilities for seeing and thinking about arts education
