Hi So for those who would like, here is the link to the full paper: http://healthhacker.org/biella/coleman-codes-value-draft.pdf It will be up only for the next few days and please don't redistribute but do read and give any comments you may have!! :-) I think it will make (much) more sense if read with the dissertation abstract: http://healthhacker.org/biella/coleman-abstract.pdf Gabriella
