THE WORK SHOWS THAT INDIVIDUALS VARY REGARDING 'CRIMINAL TENDENCIES,' AND THAT THEIR SURROUNDINGS VARY CORRESPONDINGLY. FROM A PSYCHOLOGICAL POINT OF VIEW, THE CONCEPT OF CRIMINALITY AS AN ABSOLUTE AND STATIC STATE IS WITHOUT CONTENT. CRIMINALITY NEITHER NEITHER CHARACTERIZES THE PERSON IN HIMSELF NOR THE CURRENT ENVIRONMENT AS SUCH, BUT MUST BE REGARDED AS AN EFFECT OF THE INTERACTION BETWEEN THE INDIVIDUAL AND HIS CURRENT ENVIRONMENT. BY MEANS OF A STOCHASTIC MODEL, OPERATING WITH PARAMETERS FOR THE INDIVIDUAL PERSON AND PARAMETERS FOR THE SPECIFIC CURRENT ENVIRONMENT, AN ACCOUNT IS GIVEN OF HOW CRIMINALITY AMONG NAVAL PERSONNEL MAY BE DESCRIBED FROM A MODEL OF INTERACTION PRESENTED IN THE STUDY. THE INVESTIGATION INTRODUCING INDIVIDUAL-CENTERED STOCHASTIC MODELS OF INTERACTION IN CRIMINOLOGY ALSO ILLUSTRATES THE PROBLEMS OF STANDARDS OF REFERENCE WHICH CRIMINOLOGY FACES, ALONG WITH THE CONCEPTION OF CRIMINALITY IN ITSELF. BASED ON THE INVESTIGATION RESULTS, A GENERAL, DIALECTICAL MODEL FOR CRIMINALLTY IS FORMULATED, A MODEL WHICH ALSO RESULTS IN A CRITICAL DISCUSSION OF THE CONCEPT OF ADJUSTMENT. THE INVESTIGATION WAS CARRIED OUT IN COPENHAGEN, DENMARK. (AUTHOR ABSTRACT MODIFIED--VDA)
