Response to Cummings

Reaction to Cummings on Addiction

Cummings (December 1979) is to be vigorously applauded for bringing to light the seriousness of the drug and alcohol addiction problem and the inability of traditional psychotherapy to deal with this problem effectively. Those of us who work daily with addicted people hold most of Cummings's statements to be self-evident, but we suffer frequent frustration at the apparent unwillingness of other...

Response of the strongly driven Jaynes-Cummings oscillator.

We analyze the Jaynes-Cummings model of quantum optics, in the strong-dispersive regime. In the bad-cavity limit and on time scales short compared to the atomic coherence time, the dynamics are those of a nonlinear oscillator. A steady-state nonperturbative semiclassical analysis exhibits a finite region of bistability delimited by a pair of critical points, unlike the usual dispersive bistabil...

Jay Cummings: Research Statement

My research has touched many areas of combinatorics, including enumerative, algebraic, spectral, extremal and probabilistic. The projects below include finding the stationary distribution of a random coloring procedure, pursuing new directions in the math of juggling, working with undergraduates on Ramsey theory, and studying a pair of topics from spectral graph theory. I have mentored undergra...

Stephen Cummings And

philosophy behind Images of Strategy are outlined. We argue that the conventional twentieth-century history of management and strategy leads us to unquestioningly assume that organizations are, for all people at all times, triangular hierarchies; that strategy is enacted by ‘the men at the top’, and that it is about longterm planning, directing, organizing and controlling. At a philosophical le...
