The acquisition and exchange of (tacit) knowledge relies on interpersonal interactions and is thus time- and place-dependent. Given that the combination of heterogeneous knowledge stocks furthers innovation, organisations develop strategies to ensure the transfer of knowledge. To enable intra-organisational knowledge flows spatial mobility at the workplace affects a wide range of employees. The study examines in which ways spatially mobile employees, i.e. expatriates, contribute to those knowledge flows. The study of ego networks reveals not only social dynamics of knowledge transfer, but the geographical framework allows to discuss knowledge flows from a spatial perspective. On the one hand, the empirical results confirm their knowledge transfer function. On the other hand, the relational geographical perspective reveals that expatriates do not represent a homogeneous group, but their roles in the knowledge transfer process, the geographical reach of their networks and their knowledge resources depend on job-, knowledge-, individual- and space-related factors.Perspektiven der Humangeographie,2524-3381Social sciencesHuman geographySocial Sciences, generalhttps://scigraph.springernature.com/ontologies/product-market-codes/X00000Human Geographyhttps://scigraph.springernature.com/ontologies/product-market-codes/X26000Social sciences.Human geography.Social Sciences, general.Human Geography.650.13Hünnemeyer Vanessa Rebeccaauthttp://id.loc.gov/vocabulary/relators/aut897719MiAaPQMiAaPQMiAaPQBOOK9910416146603321Knowledge Transfers over Geographical Distance in Organisations2005650UNINA05467nam 2200721 450 991045314360332120200520144314.00-12-810050-80-12-417103-6(CKB)2550000001127058(EBL)1457948(OCoLC)859836271(SSID)ssj0001139696(PQKBManifestationID)11748014(PQKBTitleCode)TC0001139696(PQKBWorkID)11213653(PQKB)11533167(MiAaPQ)EBC1457948(CaSebORM)9780124170490(PPN)176134131(Au-PeEL)EBL1457948(CaPaEBR)ebr10778197(CaONFJC)MIL527722(EXLCZ)99255000000112705820130930h20142014 uy| 0engurunu|||||txtccrIntroduction to mobile robot control /Spyros G.

The book begins with a study of mobile robot drives and corresponding kinematic and dynamic models, and discusses the sensors used in mobile robotics. It then examines a variety of model-based, model-free, and vision-based controllers with unified proof of their stabilization and tracking performance, also addressing the problems of path, motion, and task planning, along with localizationMobile robotsRobotsControl systemsAutonomous robotsElectronic books.Mobile robots.RobotsControl systems.Autonomous robots.718Tzafestas S.
