Although the public sector has promoted E-government services for many years, their uses and achievements have been below expectations so far. Therefore, this paper explores the key factors of user acceptance through a rese...

Although knowledge creation is viewed as fundamental for securing a firm’s competitive advantage by scholars of strategic management and organizational learning (Nonaka, 1994; Nonaka and Takeuchi, 1995; Prahalad and Hamel, 1990; Nelson 1990; Leonard-Barton, 1992; Teece, 2005), few studies have systematically investigated the specific knowledge creation processes put in place by small hi-tech fi...

Bn : (∀x1, . . . , xn)( if all xi are distinct then the subgraph induced on x1, . . . , xn is 3-colorable). By Erdős-DeBruijn, the countable set of axioms Bn (n = 1, 2, . . . ) defines 3-colorability. To show that 3-colorability is not finitely axiomatizable, we show the (apparently) stronger result that non-3-colorability is not axiomatizable. To do this, we use ultraproducts. It suffices to c...
