Dear tshin - Thank you for the opportunity to edit your interesting manuscript.&nbsp; As per your instructions, I've paid particular attention to grammar, tense, word choice and sentence structure.&nbsp; I have not changed the format.&nbsp; In citations, I did change perhaps one in which the comma was misplaced; otherwise I have not touched them.&nbsp; I've made Comments in a few places where it seemed to me that your meaning&nbsp;might&nbsp;not be&nbsp;clear, just to call special attention to those particular passages.&nbsp; Please let me know if you have any questions or concerns.&nbsp; Thanks again for the pleasure of working with you.&nbsp; RebeccaTDE
