hegemonicas is incorrectly written, and should be written as "hegemonic" being its meaning:
Plural feminine adjective of hegemony, the Greek hegemony hegemonies that means action guide, address, authority, pre-eminence, command of troops. In the classical Greece this word made military sense: the Supreme direction of the army. For us it means domain of an institution, whether military, political, cultural or type it, the others of the same kind.
