Structural Holes, Innovation and the Distribution of Ideas

چکیده
We model knowledge diffusion in a population of agents situated on a network, interacting only over direct ties. Some agents are by nature traders, others are by nature “givers”: traders demand a quid pro quo for information transfer; givers do not. We are interested in efficiency of diffusion and explore the interplay between the structure of the population (proportion of traders), the network structure (clustering, path length and degree distribution), and the scarcity of knowledge. We find that at the global level, trading (as opposed to giving) reduces efficiency. At the individual level, highly connected agents do well when knowledge is scarce, agents in clustered neighbourhoods do well when it is abundant. The latter finding is connected to the debate on structural holes and social capital.

Optimization of infinite composite plates with quasi-triangular holes under in-plane loading
This study used particle swarm optimization (PSO) to determine the optimal values of effective design variables acting on the stress distribution around a quasi-triangular hole in an infinite orthotropic plate. These parameters were load angle, hole orientation, bluntness, fiber angle, and material properties, which were ascertained on the basis of an analytical method used by Lekhnitskii [3]. ...
متن کاملLeveraging Structural Holes For Innovation: The Moderating Effects Of IT-Enabled Absorptive Capacity
Innovation has been a topic of considerable interest to researchers and practitioners. Particularly, the networks within which firms operate and their properties (e.g., structural holes) are suggested to affect firms’ innovation performance. One stream of research finds that structural holes are conducive to firms’ innovation because of the heterogeneous information about alternatives that firm...
متن کاملAn Innovation in Film Cooling of the Gas Turbine Blades Applying an Upstream Jet
A new design concept is introduced to control the near-wall integration between the hot-gas boundary layer and the cooling jets in order to enhance the adiabatic film cooling effectiveness of the gas turbine blades. In this new approach, another film cooling port, having a very low blowing ratio, which prevents formation of the counter-rotating vortex pare, is applied just upstream of the main ...
