Abstract

fetched live from OpenAlex

US trade officials are seeking to resolve a dispute over Mexico’s ban on genetically modified corn imports and the country’s plan to phase out the herbicide glyphosate by 2024. On March 6, the Office of the US Trade Representative (USTR) requested technical consultations with Mexican officials under the US-Mexico-Canada Agreement (USMCA), a trade pact between the North American countries. The US claims that Mexico’s Feb. 13 ban violates the USMCA. Mexico says it wants to ensure that only corn native to Mexico is used to make tortillas there as part of an effort to maintain the biodiversity of corn in the country. Mexico is home to more than 64 types of corn, 59 of which are endemic, according to the country’s Ministry of Economy. Pesticide makers and US corn growers are urging trade officials to take swift action under the USMCA. Mexico is one of the top markets for US

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.
