In this series of lectures the basic ideas of the 1=m Q expansion in QCD (m Q is the mass of a heavy quark) are outlined. Applications to exclusive and inclusive decays are given.

I examine how firms use alliances to respond to the alliance networks of their rivals, by either allying with their rivals’ partners or by building countervailing alliances.

What is not so obvious is that the health of the poor is harmed in proportion to the size of the gap between rich and poor.
