ACKNOWLEDGMENTS

 I thank my wife for helping me to have the time to complete this very time consuming

endeavor. She had great perseverance through her first trimester of pregnancy while I was

working on this research. If she had not worked so hard along side me, this research would

never have been completed. I also want to thank my daughter for being so patient. She wanted

to play with me all the time since I was at home so much, typing away on the computer. Finally,

I want to thank Dr. Hinze for giving me the idea for this study and for making it possible for me

to complete it. He took time from his busy schedule to help me finish on time.
