Fig. 7. Indicators of sustainable development for the city of Seattle in an orientation-theoretical framework after Bossel (1999). Only two of the original Seattle indicators are not used in this scheme: public participation in the arts and arts instruction. Indicators in square brackets [ ... ] are suggested additional indicators that were not on the original list. In this context, the basic orientors or fundamental interests of the system are as follows: X = existence, E = effectiveness, F = freedom of action, S = security, A = adaptability, C = coexistence, P = psychological needs.
