We describe some recent investigation about the structure of generic D=4,5
theories obtained by generalized dimensional reduction of D=5,6 theories with
eight supercharges. We relate the Scherk-Schwarz reduction to a special class
of N=2 no-scale gauged supergravities.Comment: Contribution to the proceedings of ``NathFest'' at PASCOS conference,
