Hello and welcome to the page. In addition to the presentation I did in the class on April 29, 2002, here I provide you with some more detailed discuss about the topic of my presentation. Actually I sneaked through some different sites, message boards and use-nets. I even discussed them with a few friends of mine over the internet about them so here I thank Lydia Roshanzamir (UK), Julie Saravo (France), Paula Hernández (Mexico) and Malene Juhl (Denmark) for their comments and ideas.
