Bibliographic record
Abstract
Aging and Physically Active Lifestyle ProjectDocument no. 3 Public policies conducive to the adoption and maintenance of a physically active lifestyle in the context of the aging of the population in five OECD countries.The Aging and Physically Active Lifestyle project is the result of the work of students on an internship at the Quebec Office of the Public Health Agency of Canada (PHAC).This project explores on an internship theme related to active living in the context of demographic and climate change.The views expressed do not necessarily reflect those of the PHAC or the INSPQ.The project is approved by the joint research ethics committee of Health Canada and the Public Health Agency of Canada, reference number CER 2021-025P.This document was produced by Corinne Baril, as part of a master's program internship at the School of Public Health at the University of Montreal, option Health systems and policies.This 16-week internship took place in the fall of 2022 in the Knowledge Unit of the Quebec Office of the PHAC, under the supervision of Lucie Lapierre (researcher-analyst) and Mathieu-Joël Gervais (scientific

How this classification was reachedexpand
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.
