The Program builds on the scholarly strengths of the University of Toronto in the social sciences, humanities and public health. [...] Staking out the political and institutional loci of public health expertise and power in Ontario, Powell sets the scene for the Walkerton water contamination scandal and the SARS epidemic, both watersheds in the history of public health in Ontario. [...] Andrea Daley is a Lupina/OGS doctoral fellow and is a PhD candidate in the Faculty of Social Work and is enrolled in the Collaborative Program in Health Services and Policy Research at the University of Toronto. [...] Her research interests include the social determinants of health and illness, health inequalities, the role of theory in health research, and the relationship between knowledge, policy and practice in the area of public and population health. [...] In the first section of this paper, I discuss the most pervasive epistemological approach to the analysis of self-report qualitative data in the health sciences.
