Exploration and exploitation as learning strategies among entrepreneurs: Examining associations with entrepreneurial knowledge

In this paper we examine how exploration and exploitation, as two alternative learning strategies of entrepreneurs, influence the acquisition and development of entrepreneurial knowledge from prior career experience. In line with expectations based on experiential learning theory we find significant and direct associations between entrepreneurs’ career experience and their entrepreneurial knowledg

Abstract in German 1. Begriffsgeschichtliche Annäherung: Wovon sprechen wir, wenn wir die Begriffe 'Arbeit' und 'Beruf' im chinesischen Kontext verwenden? Welche (historischen) Entwicklungen haben diese Begriffe durchlaufen, wie unterscheiden sie sich von bestimmten deutschen/europäischen Entwicklungen? Welche Rolle spielen hierbei bestimmte Wendepunkte in der chinesischen Geschichte? 2. Offiziell

Another look at weak feedback polynomials in the nonlinear combiner

Feedback polynomials with low degree multiples of low weight should be avoided in linear feedback shift registers when used in nonlinear combiners. We consider another class of weak feedback polynomials, namely the class when taps are located in small groups. This class was introduced in 2004 demonstrating that the resulting distinguishing attack can sometimes be better than the one using low weig

Radiation efficiency and surface waves for patch antennas on inhomogeneous substrat

In this paper the surface wave characteristics, as well as the radiation efficiency and the directivity of a patch antenna, with a given current distribution, located on top of an inhomogeneous, isotropic substrate are calculated. The substrate is infinite in the lateral directions and inhomogeneous with respect to the height coordinate. The surface waves in the substrate are analyzed using the pro
