Aspect ratio for mesh partitioning

This paper deals with the measure of Aspect Ratio for mesh partitioning and gives hints why, for certain solvers, the Aspect Ratio of partitions plays an important role. We define and rate different kinds of Aspect Ratio, present a new center-based partitioning method which optimizes this measure implicitly and rate several existing partitioning methods and tools under the criterion of Aspect Ratio.

A new 14+: vocational diplomas and the future of schools, colleges and universities. An educational and campaigning pamphlet

Written in an accessible and campaigning style, this pamphlet affords a valuable context to the introduction of the first group of specialist diplomas for 14 year olds in September 2008. The diplomas are the latest in a line of failed initiatives that have sought to provide vocational ‘alternatives’ for those young people staying in full-time education and not considered ‘academic’. Rather than developing any useful employment skills, Allen and Ainley argue that their introduction reflects the changing significance of education in the division and social control of learners that now extends from school to college and on to university. Those who are opposed to the current post-14 agenda, must not only put forward radical alternatives to the current curriculum offer but also, the authors argue, address issues of democracy and accountability. To do this, teacher trade unionists must make new types of alliances with local communities and also with their students.
