Hello,
I realize this is quite an old post to reply to, but as I was going through the "archives" I ran across this post. Through a bit of research I have tried to do in Google Books, I have run across some old articles that may be the same as those originally posted, but do not know. Since these are subject to copyright agreements made by Google and many publishers, I suppose that posting links to these legally available to the public works, would not violate any applicable laws and the said consequences to posters or moderators. If I am wrong, please delete the posts and edit as you see fit.
