Abstract

fetched live from OpenAlex

The study evaluated the potential impacts of refuge requirements for Bt cotton in India on world cotton markets. The objective was accomplished by estimating regional cotton yield functions in the Indian fiber model, and connecting it with rest of the world fiber model. Results revealed that the refuge requirements have potential to impact world cotton markets; magnitudes of impacts are smaller, however. The world cotton trade would be lower, and the cotton prices would be higher under higher refuge requirements, and vice versa. As the refuge requirements for an insecticidal Bt technology depend on its replacement rate, the time spent in R&D and regulation of the technology has implications for Bt crops refuge requirements and world commodity markets. Key words: Bt cotton, India, refuge requirements, world cotton markets, world fiber model.

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.
