Apparently, the "fulltext" pdf version of the article/paper referenced in the original post, is no longer available from SpringerLink via the URL provided (
http://www.springerlink.com/content/...m/fulltext.pdf) -- seems that the open access time has expired.
So, I have now included a copy of the report from the original link as an attachment to this post (see below).
Overall, it seems that some progress has been made on this forum, in relation to "reclaiming" the
definition of sustainability. So perhaps this is now an opportunity to move beyond "definitions" and into some of the other aspects raised here, especially in the context of recent events in the global economy.
