Abstract

fetched live from OpenAlex

The pursuit of greater competitiveness and efficiency today goes hand in hand with concerns directly linked to sustainable development. The traditional sugar-energy sector, with a strong influence on the economy since colonial Brazilian periods, not only played a pioneering role in replacing fossil fuel with renewable resources but is also characterized by substantial production-related differences. The Brazil is currently the largest global producer of sugarcane, and the state of São Paulo, in southeastern Brazil, leads this production. The objective of this research was to analyze the sustainable efficiency of sugarcane mills in the state of São Paulo, through Data Envelopment Analysis (DEA). For this, the work was based on the Triple Bottom Line, considering environmental, economic and social approaches to the performance of the mills. Regarding the main results, it was possible to notice that the production scale factor favored large mills in some points of analysis, while at other times, small mills were highlighted.

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.
