Dear Liz,
Here is the PhD1 articles map. In terms of direct overlap between PhD1 and PhD2 there is really only about 12 pages of PhD1 that will feed into PhD2. This is a section of the Discussion in which I describe on a theoretical level the 'collaborative reflective action technology' and the neurology that lies at its basis. This is sooo very theoretical that there really is another PhD's worth of work to actually create a form of this technology that can be put into practice! 

The green nodes represent chapters from PhD1.

The blue component nodes represent articles that can be extracted quickly and easily from the thesis. These articles are really no more than a copy, paste, trim and add abstract job.
 
The orange issues nodes represent articles that will take more effort to extract from the thesis. These articles generally require more writing and, in some cases, more or updated research.
 
Article nodes are generally linked to as many of the chapters as they will require content from - as best as I can see from here. I have also started the process of linking article nodes to related articles and to 'related research' nodes on other graphs.
