"This X" is a way of defining something which sounds a bit stilted to many people over the age of 30. It seems to have come into popular use in the first few years of George Dubya's presidency when George, and many politicians (mostly conservative side) started to describe "the USA" as "this country" and "this country of ours" rather than "our country" or "the United States of America." I looked around for a while to try to discern whether it was a Bush-ism or someone else's schtick. I have not found the source if it is not George Dubya (or his speechwriter's).
"This" has become a word which implies inclusiveness without saying 'our' which sounds too possessive to some people. It no longer seems to be a way of commenting about the the thing specifically (while insinuating that the observation may not apply to other ones). Personally, I find the usage to be annoying and contrived, but it certainly has gained a foothold in this language (smirk).
