Unified tretment of Gautschi-Kershaw type inequalities for the gamma function

Gautschi, kershaw, Lorch, laforgia and other authors gave several inequalities for the ratio G(x+1)/G(x+s) where, as usual, G denotes the gamma function. In this paper we give a unified treatment of all their results and prove, among other things, new inequalities for the above ratio, which involve the psi function.
