Get the News on Physical Activity Research: A Content Analysis of Physical Activity Research in the Canadian Print Media
Bibliographic record
Abstract
BACKGROUND: News media may play a critical role in disseminating research about physical activity and health. This study examined how much physical activity research gets reported in the media and its prominence and credibility. METHODS: A content analysis was conducted of the reporting of physical activity research in Canadian national and local newspapers from November 2004 to April 2005. RESULTS: Physical activity research was given some prominence and treated as news through the use of several devices to infer credibility. However, newspapers appeared to invest little in the production of physical activity research as news and information about research methodology was infrequent. CONCLUSIONS: While stories reporting physical activity research were given some prominence and credibility, the lack of significant investment and the limited reporting on research methodology suggests that important aspects of research related to physical activity may not be well represented in newspaper coverage.

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.
