I have decided in light of this flurry of emails to go into more detail on some future blog entries. Look out for 'In depth' in the titles for future entries where I will explain more comprehensively the methodologies and materials used in select studies.
http://www.sciencedaily.com/ is a great website which does a far better job at summarising scientific articles, where sadly, there isn't much on there in the way of music piracy research aside from this excellent article which demonstrates how the removal of DRM restrictions may reduce piracy. This sort of research would fall under the previously mentioned broad area that is 'deterrents' which will be considered in future blog posts.
Also, please see http://www.ted.com/ which presents excellent presentations by researchers and public figures (freely available to the public) including a recent addition where the concept of copyright math is proposed. It highlights the difficulties in measuring losses due to piracy. TED can also be found on Twitter @TEDTalks
I also direct you to the UK governments January 2012 POSTnote publication (short briefing notes by the Parliamentary Office of Science and Technology) by Chadrika Nath, which calls for open access to scientific information. It is a big discussion point just now, with an article in The Psychologist May 2012 magazine also calling for access to such information for journalists, to check and confirm findings before publishing.
If this is something you want to discuss, please email me or leave a comment. Twitter feed also now online @musicpiracyblog
For now, please see the 'Resources' page above with some general advice on searching for articles online, where you should be able to find out more by simply searching for articles on Google using good keywords.
Hope this information is useful and worthwhile.
