It is commonly argued that we are witnessing a shift from global production networks, driven by the search for markets and lower cost production sites, to global innovation networks (GINs), driven by the search for knowledge. This paper explores how sources of behavioural differentiation derived from the literature on industrial knowledge bases and technological regimes condition the degree of involvement in international innovation collaboration. We find this to be significantly influenced by the nature of knowledge and the cumulativeness of knowledge development, the active use of measures to protect intellectual property, the inherent need to innovate and the opportunity to generate sales from this activity. The likelihood that the firm establishes and maintains a truly global network configuration is influenced accordingly. 相似文献

Abstract In research on motor control, the detrimental effect of an internal focus of attention on movement execution of well-learned motor skills is a frequently replicated finding. This experimental study was designed to determine whether this effect is observed with physiological variables during endurance exercise. We examined whether the focus of attention can influence running economy (oxygen consumption at a set running speed). Trained runners had to focus their attention on three different aspects while running on a treadmill. For three consecutive 10-min periods, runners concentrated on the running movement, on their breathing, and on their surroundings. Results showed an increased running economy in the external focus condition. In line with research on motor control, endurance sport also shows that an external focus of attention is better than an internal focus in terms of the physiological performance measure of oxygen consumption. 相似文献

Dinghy sailors lean their upper body over the windward side of the boat (‘hiking’) to keep the boat’s balance and maximise its speed. Sustaining the hiking position is essential for competitive performance and this study examined sport-specific differences of muscles relevant for hiking in elite sailors. Knee extensor muscle strength as well as trunk muscle strength, muscle endurance and muscle thickness were assessed in elite dinghy sailors (n = 15) and compared to matched, non-sailing controls (n = 15). Isometric extensor strength was significantly higher in sailors at 60° (+14%) but not at 20° knee flexion. Sailors showed significantly higher trunk flexor (but not extensor) strength under isometric (+18%) and eccentric (+11%) conditions, which was associated to greater muscle thickness (rectus abdominis +40%; external oblique +26%) and higher endurance for ventral (+66%) and lateral (+61%) muscle chains compared to non-sailors. Greater muscles thickness and the particular biomechanical requirements to maintain the hiking position may drive the increases in isometric and eccentric muscle strength as well as ventral and lateral trunk endurance. The current findings identified sport-specific muscle function differences and provide performance benchmarks for muscle strength and endurance in elite sailors. 相似文献

§ 85 UG erm?glicht die Ersetzung einer im Curriculum vorgeschriebenen wissenschaftlichen oder künstlerischen Arbeit durch eine sonstwo an einer anerkannten inl?ndischen oder ausl?ndischen postsekund?ren Bildungseinrichtung positiv beurteilte Arbeit im Wege der Anerkennung. Ma?gebliches Kriterium hiefür ist die Gleichwertigkeit zwischen ausw?rtiger und heimischer Arbeit; die Anerkennung kann auch studienrichtungsübergreifend erfolgen. In dieser Weise suppliert werden k?nnen Diplom- oder Masterarbeiten sowie künstlerische Diplom- oder Masterarbeiten, nicht jedoch Bachelorarbeiten und Dissertationen. W?hrend dies für Bachelorarbeiten sachlich gerechtfertigt werden kann, erweist sich der Ausschluss von Dissertationen aus dem System des § 85 UG als gleichheitswidrig. 相似文献
