In this edition the appendix on the methods used in the study appears as footnote 11.

We have organized our presentation of this study by means of Robert K. Merton's concepts "status", "status-set", "status-sequence, "role", and "role-set" [31]. Since the text is written also for non-sociologists we have omitted the full use of these technical terms. Below is a reconstruction of a chart used by the author in 1954-56 to present these concepts for his sociology students in the School of General.
