A critical discourse analysis of Canadian and Australian public health recommendations promoting physical activity to children
Bibliographic record
Abstract
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
