In some countries, the student's advisor serves as the chair of the doctoral examination or dissertation committees. In some cases, though, the person who serves those roles may be different from the faculty member who has most closely advised the student. For instance, in the Dutch academic system , only full professors ( hoogleraren ) may chair doctoral examinations, so students who have been advised by lower-ranked faculty members will have a full professor as their official advisor (or promotor ) and their actual advisor as co-promotor .  In other countries, such as Spain, the doctoral advisor has the role of a mentor, but is not allowed to form part of the examination committee. This is a body of 5 experts independently selected by the rectorate among 10 candidates proposed by the university's department.

The first requirement for such a "deepening" was to recognize the multidimensional nature of power in the world: there was no single index by which the influence of states could be measured. Nuclear weapons , given the constraints on their use in an approaching era of parity , were of decreasing practical utility . Kissinger liked to point out that in no crisis since 1962 had the strategic balance determined the outcome. Vietnam had amply demonstrated the limits of conventional military force applied under constraints imposed by public opinion and the dangers of escalation. Ideology was proving to be a feeble force when arrayed against the compulsions of nationalism; territory bore little relationship to political influence; economic strength seemed at times to have little to do with any of these. And, underlying all of these complexities, there was the increasing importance of psychology: the perception of power had become as important as power itself.
