There's an interesting lecture coming up in the Gloucestershire Network on 11 July 2013 at Cheltenham Racecourse. Its being given by Professor Nigel Linge from University of Salford. I've heard several of his talks and he's an excellent communicator and very informative and interesting.
There's more information on the Network website at: http://www.theiet.org/events/local/172773.cfm
The event is open to all and free to attend.
