<http://www.zcommunications.org/ready-or-not-can-bangladesh-cope-with-climate-change-by-hazel-healy> is a copy of a page on our site created by the author, and links back to that page. Google's guidelines suggested to me that this would be enough for Google to recognise our page as the canonical one and that one as the duplicate, and thus to show our page in SERPs. However, the opposite has happened - if you [search for the page's title](https://www.google.co.uk/webhp?sourceid=chrome-instant&ix=h9&ie=UTF-8#hl=en&output=search&sclient=psy-ab&q=%22Ready%20or%20not%3A%20can%20Bangladesh%20cope%20with%20climate%20change%3F%22&oq=&aq=&aqi=&aql=&gs_l=&pbx=1&fp=635d3d5ebe63a17&ix=h9&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.,cf.osb&biw=896&bih=882) you'll see the duplicate page shows up but ours doesn't.

How can we prevent this? Since the author 'owns' the duplicate page on zcommunications.org she can edit the HTML body, but not the `<head>`.
