Implications for Minimum Unit Pricing Advocacy: What Can We Learn from UK Newsprint Coverage of Key Claim-Makers in the Policy Debate?
Bibliographic record
Abstract
On May 24th 2012, Scotland passed the Alcohol (Minimum Pricing) Bill. Minimum unit pricing is a legislative intervention intended to raise the price of the cheapest alcohol to reduce alcohol consumption and related harms. Communications and political sciences literatures offer a theoretical framework to investigate how competing frames about policy issues are presented in the news media from key claim-makers. Content analysis was conducted on seven UK and three Scottish national newspapers between 1st May 2011 and 31st May 2012. Relevant articles were identified using the electronic databases Nexis UK and Newsbank. A total of 262 articles were eligible for detailed coding and analysis. This paper attempts to map out the dynamic interplay between media framings from key claim-makers of what constitutes the alcohol problem and the arguments for and against minimum unit pricing in the months leading up to the passing of the legislation, with a view to informing policy advocacy.

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.
