Recent experiments on the pressure dependence of the superconducting transition temperature Tc of ZrxNi100-x glasses have revealed that the pressure derivative of Tc is positive for x greater than 60 and negative for x less than 60. In order to see whether this behavior can be explained entirely on the basis of pressure-induced changes in the electronic structure, the authors have carried out some standard linearized muffin-tin orbital (LMTO) and coherent-potential-approximation calculations. These reveal a decrease in the electronic density of states at the Fermi level for all x in the range 50
