Please be advised that your dead line is 21 December, 2007. By now, you should be reading all 4 questions and answering them. The worrying part is the reading requirements as you have to give at least 20 references in the order of 3 from text books, 7 from empirical journals and the rest from magazines and internet electronic references. For details of Harvard style of references, please refer to the handbook on communication by Jane Summers. Good luck.
