Psychiatrists in restraints.

The Psychiatrists

Although written by a professor of politics, this book is about American psychiatrists and analysts. It describes two different 'tribes' of doctors: analysts, more highly selected, earning more money and seeing fewer patients, who are individually more important and more influential, and general practitioners, working in mental hospitals and centres and seemingly regarded as an inferior breed. ...

In both cases, the government’s attorneys allege that the company charged with anticompetitive conduct has abused its dominant market position to extend its monopoly power from a first market to a second market. They also allege that part o...

Enhanced rigid-bond restraints

The rigid-bond model [Hirshfeld (1976). Acta Cryst. A32, 239–244] states that the mean-square displacements of two atoms are equal in the direction of the bond joining them. This criterion is widely used for verification (as intended by Hirshfeld) and also as a restraint in structure refinement as suggested by Rollett [Crystallographic Computing (1970), edited by F. R. Ahmed et al., pp. 167–181...

Graph coloring satisfying restraints

For an integer k 2 2, a proper k-restraint on a graph G is a function from the vertex set of G to the set of k-colors. A graph G is amenably k-colorable if, for each nonconstant proper k-restraint r on G, there is a k-coloring c of G with c(v) # r(v) for each vertex v of G. A graph G is amenable if it is amenably k-colorable and k is the chromatic number of G. For any k Z= 3, there are infinite...
