***** To join INSNA, visit http://www.insna.org ***** Dear All When examining structural holes, it is possible to calculate the aggregate constraint of an ego. The value of the aggregate constraint is usually between 0 and 1, but it can be greater than 1. I think I read somewhere that the maximum value possible (greater than 1) has been proved. I have mislaid the reference. Might anyone be able to inform me of the reference? Of the maximum value?
