The ability to incorporate an innovation in time or to solve a problem efficiently can mean competitive advantages for some firms. Being responsive in IT involves being alert, knowledgeable and prepared to face technical problems and to solve them in appropriate ways. In...

We define the notion of a weakly pointed tree, and characterize the amount of genericity necessary to prevent a uniformly branching tree being weakly pointed. We use these ideas to show there is no topological analogue of a measure-theoretic selection theorem of Graf and Mauldin. We consider some topological and recursion-theoretic questions motivated by the following measure-theoretic result o...
