Introduction The business value research, after the initial findings of missing impact of IT systems, has focused on alternate mechanisms that affect performance of IT systems (Loveman 1994, Barua and Mukhopadhayay 2000, Brynjoffsson and Hitt 1996). Amongst the various processes that affect the value realization of IT, a critical factor is related to the complementary processes and mechanisms t...

In 7 experiments, undergraduates judged the force exerted by a videotaped standing puller, a computer-generated (stick-figure) puller, or a computer-generated inverted pendulum. Single and stepwise multiple regression analyses determined the kinematic variables exploited by the participants. Results show that (a) judgments correlated highly with force and improved with feedback; (b) judgments c...

This article reports that some robustness of the notions of predicativity and of autonomous progression is broken down if as the given infinite total entity we choose some mathematical entities other than the traditional ω. Namely, the equivalence between normal transfinite recursion scheme and new dependent transfinite recursion scheme, which does hold in the context of subsystems of second or...
