In the past decades, public health has increasingly addressed what has been called the children's obesity 'epidemic', most notably through large-scale initiatives promoting physical activity. Through a discourse analysis the current paper critically examines such efforts in Canadian and Australian public health. Public health websites in Canada and Australia were examined for information concerning children's health, physical activity and obesity and explored for how these issues were represented in the discourse. Bacchi's (2009) 'What's the problem represented to be?' approach to discourse analysis guided our interrogation of the taken-for-granted assumptions underlying Canadian and Australian public health discourse, the ideological and political influences involved in its construction, and the knowledge base upon which it rests. The article calls for critical reflection on how children's physical and leisure activities are being advanced. [ABSTRACT FROM AUTHOR]

Since 2003, avian influenza has recently spread around the world sparking fears of a potential pandemic. As a result of this, a range of explanations and expectations surrounding the phenomenon were generated. Such social representations of disease depict the issue under discussion and frame reactions to the event. This paper explores the social representations surrounding avian influenza in Australia. Methodologically, a textual analysis of media and government documents was conducted in order to uncover the social representations implicit in these accounts. This demonstrated a symbolic framing of avian influenza with reference to the Spanish Influenza pandemic (1918). Analytically, the study draws upon the concepts of social representations from Durkheim and of risk and symbolic risk in the work of Beck. Overall, it is argued that the framing of avian influenza as a risk, mediated through the collective memory of Spanish Influenza, characterised the nature of the social representations surrounding the phenomenon. This resulted in the production of symbolic solutions to the threat. [ABSTRACT FROM AUTHOR]
