A Multiple Streams Analysis of E-Cigarette Policy in Ontario
Bibliographic record
Abstract
In October 2018, the Ford government in Ontario reversed the previous Wynne government’s ban on promoting vaping products, such as e-cigarettes. However, in October 2019, the Ford government enforced the vaping promotion ban again and in February 2020 passed further regulatory restrictions. This study seeks to understand what prompted these changes by applying the Multiple Streams Framework. In-depth interviews were conducted with key stakeholders from government, non-governmental organizations, universities, and trade associations (n=15). Legislative debate transcripts (n=10), committee proceeding transcripts (n=11), and newspaper articles (n=101) were also collected. Data was coded and thematically analyzed, which showed that the first reversal occurred because of the election of the Progressive Conservative Ford government. The second reversal occurred because of the rise in youth vaping and the e-cigarette or vaping product use associated lung injury (EVALI) outbreak, which focused the attention of policymakers on the vaping problem.

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.
