The project had three objectives: (1) to examine from a multi-disciplinary perspective the theoretical and operational meanings of the concept occupation, to develop a conceptualization which could synthesize the major emphases extant in several disciplines and to develop reliable measures of occupational characteristics consistent with the new conceptualization and practically usable with common occupational classification systems; (2) to provide support for the continuation of field work and data preparation for the follow-up study of men and women first interviewed by James Coleman in 1957 for his study, "The Adolescent Society," to initiate new field work to conduct telephone interviews with the subjects of the Coleman study who had not previously responded to mailed questionnaires, to develop machine-readable life history portfolios containing information about life experiences which had occurred since the initial data collection, and to combine the newly collected data with data collected prior to the grant for this project, thus completing all data collection procedures; and (3) to analyze the resulting matched-merged longitudinal data file and synthesize findings pertaining to long-term consequences of adolescent social systems within the tradition initiated by Coleman.
