Hi Jonathan. There's a great deal of information on unitary systems. Here's an interesting paper on the quality of governance in federal and unitary systems: http://www.bu.edu/sthacker/files/2012/01/Are-Federal-Systems-Better-than-Unitary-Systems.pdf

Thank you Pedro. It is a little overdue for my intended assignment, but as you said, it is a very interesting paper indeed and one that I will keep note of for future use. I happened to find a book by K. C. Wheare regarding the federal test to be a real gem in itself too.

In the light to understand the very peculiar constitutional arrangement and phenomena as Unitarism and unitary form of government, I will offer you valuable handbook published by Oxford University Press in 2012. It covers virtually all modern constitutional concepts, terms and trends inter alia unitary organization of the polity or state.
