The research and policy discussions included in Aboriginal Policy Research, Volume 4, offer a portion of the original papers presented at the second Aboriginal Policy Research Conference held in Ottawa in 2006. Co-chaired by Dan Beavon of Indian and Northern Affairs Canada, Jerry White of the University of Western Ontario, and Peter Dinsdale of the National Association of Friendship Centres, the conference promoted interaction between reasearchers, policy-makers, and Aboriginal peoples. It expanded knowledge of the social, economic, and demographic determinants of Aboriginal well-being, and sought to identify and facilitate the means by which this knowledge may be translated into effective policies. Volume 4 begins with a look at health and health care followed by issues of governance, and concludes with and examination of housing and homelessness.
