ii ACKNOWLEDGEMENTS First and foremost, I would like to thank Dr. J. Jill Suitor, my examination committee chair. Her guidance and suggestions were crucial contributions to this thesis. Dr. Suitor’s incredible patience and willingness to spend time working with me surpass points of reasonable generosity. In addition, Dr. Suitor was kind enough to offer me the use of, unquestionably, the component most vital to this thesis; the data set. I would also like to extend my thankfulness and appreciation to the other two members of my examination committee, Dr. Yoshinori Kamo and Dr. Susan Dumais, first for their readiness to serve on my committee, and second for their insightful comments and suggestions that enhanced this thesis. My sincere appreciation goes to my professors, both at LSU and UWSP. You have played a critical role in this process, whether it by awakening my interest, inspiring me to learn, or instilling in me knowledge. Also to my family — you taught me to value education and have always encouraged me, both gifts of infinite value
