Jackson, <br /><br />I revised many sections. Here is the latest version. Please skip the subtitles and sentences in GREEN. I am supposed to use Chicago style but I have not started inserting the footnotes. <br /><br />I have two more sections and conclusion. I will send them shortly. I also have to write another paper. That one is short so I will finish it by tomorrow night and send you as soon as possible. <br /><br />Emma
