"R&D is an activity related to a number of others with a scientific and
technological basis. Although these other activities are often very closely
linked to R&D, through flows of information and in terms of operations,
institutions and personnel, they must be excluded when measuring R&D.
R&D and these related activities may be considered under two headings: the family of scientific and technological activities (STA) and the process of scientific and
technological innovation (Frascati 2002: 18)."
