Corporate decision-making in R&D outsourcing and the impact on internal R&D employment intensity

This article aims to assess whether firms’ strategies of R&D outsourcing determine changes in their internal R&D employment intensity. Four strategic decisions are investigated: to start, increase, decrease or stop outsourcing. It is found that internal R&D employment intensity decreases when firms decide to start, to increase, or to stop R&D outsourcing. However, this finding hides important differences according to the type and the location of the contractor. In general, firms prefer a mix of different types of contractors at different locations. Started outsourcing of R&D to research centers within the nation and increased R&D outsourcing to research centers within the region appear to decrease the internal R&D employment intensity. Decreasing outsourcing to national universities in another region also has a negative impact on internal R&D employment intensity. A corporate decision to stop R&D outsourcing to other firms within the nation but outside the region has a positive impact on the internal R&D employment intensity. The latter is the only effect that is not only statistically significant but is also substantial in magnitude

Voor de kust van Zuid-Holland liggen verschillende zandwingebieden. Uit dit kleine gedeelte van de Noordzee komt een enorm aantal spitsen, de punten van jachtwerktuigen. Er zijn al ruim 1000 spitsen gevonden en dit worden er elk jaar meer. Wat kunnen deze spitsen ons vertellen over overlevingsstrategieën van jagers- verzamelaars

Diving into the life of a Mesolithic archer:Use wear analysis and experimental archaeology on Doggerland bone and antler points

I am reconstructing the behaviour of hunter-gatherers by use wear analysis on bone and antler points and experimental archaeology. The following aspects will be investigated:• Binding of points to shafts• Development of use wear by carrying arrows in a quiver• Development of use wear during use as arrowheads• Taphonomical processesThis research is part of my PhD project about human-red deer relationships in postglacial Doggerland. The overarching NWO project is called Resurfacing Doggerland
