Checks and balances at home require a correlative balance of power abroad.

The putative benefits of the Mediterranean diet for cardiovascular health are primarily correlative in nature while they reflect a very real disparity in the geographic incidence of heart disease, identifying the causal determinant of this disparity has proven difficult.

Thus, national guidelines must be prepared with respect to human rights and correlative themes (gender, religious diversity, diversity of sexual orientation, and disabilities), for the initial training curricula for professors and teachers, as well as for the curricula for early childhood, elementary, middle and high school instruction.
