When trying to understand the mathematical experiences of a child, one can do no better than to interact with the child in a mathematical context guided by the intention to specify the child's current knowledge and the progress the child might make.

In this book a global shape model is developed and applied to the analysis of real pictures acquired with a visible light camera under varying conditions of optical degradation. Computational feasibility of the algorithms derived from this model is achieved by analytical means. The aim is to develop methods for image understanding based on structured restoration, for example automatic detection of abnormalities. We also want to find the limits of applicability of the algorithms. This is done by making the optical degradations more and more severe until the algorithms no longer succeed in...

Since the establishment of the first alcohol education course (ABC) for young offenders in 1981, this fono of service delivery has been expanded across the United Kingdom. While some before-and-after data have been reported, no con trolled evaluations have been completed on effectiveness with this type of inter vention. The present research reports a series of evaluation studies to investigate the impact of ABCs on offending and drinking behavior. Young offenders were recruited from local courts. The first study, completed in Dundee, reported results from a comparative evaluation between two...
