Yes, the flux-control coefficient is the same as Kacser's Z sensitivity 
coefficient. The terminology was standardised in 

Burns, J.A., Cornish-Bowden, A., Groen, A.K., Heinrich, R., Kacser, H., 
Porteous, J.W., Rapoport, S.M., Rapoport T.A., Stucki, J.W., Tager, J.M., 
Wanders, R.J.A. & Westerhoff, H.V. (1985), Control of metabolic systems.

Bob, you are needed here! MCA has been slow penetrating the Us but I think 
we have now gone past the point of no return. See my "MCA Web" at

http://gepasi.dbs.aber.ac.uk/metab/mca_refs.htm

This is not a complete reference but maybe will help you with the 
terminology. The page of references may especially be of interest to you. 
Athel Cornish-Bowden also has web pages on MCA but his site seems to be 
down. The URLs for this are

Phil Butler from UMIST lectures a course on MCA and he's also got MCA on his 
web pages:

We know each other from several MCA related conferences. For a while there 
was a sense of frustration as it seemed the US researchers were not 
attracted to this analytical formalism. This seems to be changing now (and I 
hope you'll help this trend)
