I've done a search for the Megatrend University of Applied Sciences in Belgrade on Google. I found a reference to a Megatrend University Belgrade on Wikipedia but the only Megatrend University I can find in Belgrade has a dubious reputation (according to Wikipedia) which I think puts some doubt on Hughs' research claims.
No Megatrend University of Applied Sciences appears in Wikipedias' list which I also feel causes some concern!
