An Evaluation of the AirCare Program Based on Cost-Benefit and Cost-Effectiveness Analyses
Bibliographic record
Abstract
A cost-benefit analysis of the AirCare program in the province of British Columbia on the basis of emissions cost factors from the literature showed a benefit outweighing the cost. Furthermore, a cost-effectiveness analysis comparing the AirCare program with a hybrid-car rebate program revealed that the AirCare program is more effective in reducing emissions of major air pollutants such as NO x , hydrocarbons, and CO. However, the hybrid-car rebate program contributes significantly to the reduction of greenhouse gas emissions because of much greater fuel efficiency, although its contribution to reducing emissions of major air pollutants is small compared with that of the AirCare program. Both the AirCare program and the hybrid-car program are therefore essential to addressing both local air quality improvement and global warming issues, and the programs complement each other.

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.
