This research stream is focussed on offshore hazards, with particular attention to the mobility of the seabed – whether through large scale geological events, or local scale sediment transport processes. This report is divided into two broad areas. We have extensive activity to report on the subject of seabed mobility, through studies around the O-Tube program (see also the separate report on t...

International scientific mobility is acknowledged to be a key mechanism for the diffusion of knowledge, particularly tacit or ‘sticky’ knowledge that cannot be transferred without geographical proximity and personal contact (Frenken 2010), for the incorporation of young researchers into elite transnational scientific networks (Laudel 2005), and for accessing additional resources or infrastructu...

The paper introduces a family of three-DOFs translationalrotational Parallel-Kinematics Mechanisms (PKMs) as well as the mobility analysis of such family using Lie-group theory. Each member of this family has two-rotational onetranslational DOFs. A novel mechanism is presented and analyzed as a representative of that family. The use and the practical value of that modular mechanism are emphasized.

Article history: Received 5 July 2010 Received in revised form 10 February 2011 Accepted 10 February 2011 Available online 21 March 2011 We compare the effects of socioeconomic background (SEB) and intelligence on wage trajectories in a dynamic growth modeling framework in a sample that had completed just 12 years of education. I show that the main difference between the two is that SEB affecte...
