This symposium report presents the background, underlying assumptions, philosophy and goals, research design, sample, and results of an intensive three-year organizational study involving military, government and civilian organizations. The first paper, by S. B. Wells, discusses the organizational setting, approach and rationale of this research. The second paper, by L. R. James, presents an organizational model developed to guide the investigation and specific analyses in the present study, and combines an open systems approach with a linkage model. The third paper, by A. P. Jones, presents empirical evidence bearing upon the theoretical model. The paper by E. K. Funderson discusses aspects of the physical environment and their relationship to perceptions of the environment and to behavioral outcomes such as illnesses and accidents. The discussants, Paul Nelson and B. V. H. Gilmer review the study in terms of both its applied and theoretical applications. (Author/HMV)
