I am the author, Arch Andrew: This is a Master's Thesis using the fingerprint files of the RCMP, a one time only event, which drew wide enough interest to be placed in the Library of Congress. It identifies factors which effect individuals who return to criminal activities and re-enter prison. Probably better said that it identifies factors in persons who do not return to prison. Marriage (including common-law, divorced and separated individuals) , low number of previous offenses, and higher education (would you believe, grade eight and above) helped avoid return to prison). These factors relate to the individuals capacity in developing relationship. A general measure of social maturity.
