All papers will be refereed by member(s) of the Scientific Organising Committee. Whilst the refereeing process will be gentler than for a normal publication in a journal, we wish to ensure good standards of scientific rigour and written english, so that the published volume is of high quality; the referees are there to help you attain this (if necessary), not to make life difficult! Their aim is to point out errors and inaccuracies, not to criticise particularly the science that is presented.
