This research introduces a framework for selecting efficient inter-unit structures in facilitating the transfer of knowledge with different levels of complexity. We argue that while boundary spanner structure is efficient for transferring discrete knowledge, it is inadequate for transferring collectively held complex knowledge. We propose that the transfer of such knowledge requires a more dece...

In this paper we investigate a passivity approach to collective coordination and synchronization problems in the presence of quantized measurements and show that coordination tasks can be achieved in a practical sense for a large class of passive systems.
