Thanks for this, and all your fine work. I think you might mean "dispersion" (meaning "distribution: the spatial or geographic property of being scattered about over a range, area, or volume"). I don't think "dispursement" is a word, although "disbursement" certainly is ("Money paid out or spent")
thanks david... it was actually disbursement (fixed).
