"Doktor nauk", the next stage, implies achieving significant scientific output. This title is often equated to the German or Scandinavian habilitation. The dissertation paper should summarize the author's research resulting in theoretical statements that are qualified as a new discovery, or solution of an existing problem, or a practical proposal with significant economical or military potential. The road from "kandidat" to "doktor" typically takes 10 years of dedicated research activity; one in four candidates reaches this stage. The system implies that the applicants must work in their research field full-time; however, the degrees in social sciences are routinely awarded to active politicians.
