Hi, Huihee:<br /><br /><br />I have uploaded your edited document, and I hope that you find the suggestions helpful. If you have any questions, please send a message to me via Editor World.<br /><br />Thank you for doing the heavy lifting; it made my job much easier. I believe&nbsp;your paper reads very well now, but please read&nbsp;it over carefully. Those pesky typos have a way of reappearing even after the most careful review.<br /><br />Best wishes - George (TypeRighter)<br />I am usually available for editing between 6:00 am and 10:30 pm (EST). If my status is set to 'unavailable', you can still reach me via Editor World.
