(After the title you will want to press enter approximately 15-20 times) The top line is for the Supervising Professor's signature. There should be as many lines as there are members on the committee, and underneath each line, the typewritten name of the committee member should appear. All signatures must be original and in ink. Duplicated signatures are not acceptable The signature page is counted but the number is not typed on the page. iii ACKNOWLEDGEMENTS First, I would like to thank my academic advisor Professor Kay Robbins for her priceless helps and her patience.
