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...

a semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant ph value and constant temperature in the various relative supersaturations. results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3,  the kinetic exp...

This paper presents a generalized second-order hydrodynamic traffic model. Its central piece is the expression for relative velocity of congestion (compression wave) propagation. We show that well-known models Payne–Whitham, Aw–Rascal and Zhang are all special cases featured model, their properties fully defined by how expressed. The proposed model verified with data from segment Interstate 580...
