Until 17 November 2014, the call to groups for participation brought a return of 45 proposals for special tracks. (And still there are proposals coming in.) So the programme takes shape!
About half of them involve calls for papers. Others suggest tracks with invited people like round tables, podiums, workshops etc.
Each proposal is now carefully checked. Calls for Papers are put online one by one, once possible modifications are accorded and details fixed (go to calls for papers). – The deadline for abstract submissions is 27 February 2015. If you like to submit, you have 3 months time to do so (go to submission).
The other Tracks are published as part of the programme as soon as they are ready for publication (go to programme).
Besides, also two Conference Streams have already published their Call for Papers (go to calls for papers).
