THREE DISTINCT APPROACHES ARE IDENTIFIED: FOCUS ON THE INDIVIDUAL'S MOTIVATION FOR VIOLENCE; EMPHASIS ON THE SOCIOECONOMIC BACKGROUND OF THE INDIVIDUAL, ORGANIZATION OF THE PRISON SOCIAL STRUCTURE, AND PARTICIPATION IN QUASI-POLITICAL-REVOLUTIONARY GROUPS; AND ANALYSIS OF THE STRUCTURAL, PHYSICAL, AND PSYCHOLOGICAL ENVIRONMENT OF THE INSTITUTIONAL SETTING. NOTED IS A SHIFT AWAY FROM THIS FIRST APPROACH TO AN EMPHASIS ON THE THIRD. THE POLICY IMPLICATIONS CONSIDERED INCLUDE ATTEMPTING TO CONTROL THE MIX OF PEOPLE WITH CERTAIN CHARACTERISTICS RESIDING IN A GIVEN INSTITUTION, POSSIBLE INVOLVING THE INMATE IN THE DEVELOPMENT OF RULES AND PROCEDURES, DEVELOPING A PREDICTIVE DEVICE OF INMATE BEHAVIOR, AND ENHANCING THE OPPORTUNITIES FOR EACH INMATE TO EXPRESS HIS INDIVIDUALITY. FUTURE RESEARCH NEEDS IDENTIFIED ARE A CULTURAL-ANTHROPOLOGICAL STUDY OF THE CHICANO IN PRISON; DEVELOPMENT OF AN INTERACTIVE MODEL INVOLVING INDIVIDUAL PREDISPOSITIONS, INSTITUTIONAL STRESSES, AND SITUATIONAL INTRUSIONS; AND EXPERIMENTS INTO THE EFFECT OF SET RELEASE DATAS ON INMATE FRUSTRATIONS.
