Abstract

fetched live from OpenAlex

CANADA MOVED last week to become the world’s first country to set exposure limits on bisphenol A (BPA), a high-volume chemical used to make polycarbonate and epoxy resins. U.S. politicians proposed similar measures, and a leading supplier of plastic drinking bottles announced that it will stop manufacturing products that contain the chemical. Bowing to public concern over the health effects of BPA, bottle maker Nalgene said it will drop the use of polycarbonate. In addition, Wal-Mart, the world’s largest retailer, announced it will stop stocking baby products containing the chemical immediately in Canada and early next year in the U.S. Toy store chain Toys ‘R’ Us has also announced a BPA phaseout for these products. Scrutiny of BPA increased earlier this month with the release of a draft report by the U.S. National Toxicology Program (NTP) on the health effects of the chemical. The report concluded that although BPA is generally safe, there is “some ...

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
