A change in focus of much of the work of the Society for General Systems Research for greater impact, relevance, and productivity is suggested. Tentative unit concepts for 23 areas of study or disciplines are explored. A unit concept is defined as the central, pivotal concept around which virtually all other basic concepts in a field revolve. The unit concepts employed in this paper focus on the mechanism(s) that explain the causes of change in the system under study in a global way. The presumption is that the basic problem of how order is possible is the central issue of any science. Alternatively, a more encompassing approach emphasizes the explanation of change in an individual (unit) in the face of conflict between two or more units under investigation. As a result, a deeper understanding of the structure of the units under study at two or more points in time is possible while still focusing on the mechanisms(s) by which the units change. What is accomplished is more than a mere static analysis of structure or hierarchy at only one or two points in time. (RSL)
