Abstract

fetched live from OpenAlex

Central to the discussion of air quality degradation is its effect on health and the costs that it may impose on the health care system and the individuals whose health has been affected. Estimating the monetary benefits associated with improved air quality is problematic, as air (and its quality) is a public goods. By employing daily environmental data from Montreal and the Quebec Health Survey, a component of individuals’ willingness to pay for reductions in ozone is estimated building on the work of Gerking and Stanley (1986). The results suggest a significant relationship between ozone levels, health status and medical care consumption. The results also suggest that the monetary benefits from reducing ozone levels are greater than previously estimated.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
