Análisis comparativo de tres redes agroalimentarias alternativas en México y Canadá
Bibliographic record
Abstract
This article examines the case of three alternative agri-food networks which are considered alternative mechanisms of purchase and sale of agri-food products, namely the Organic Tianguis of Chapingo in the State of Mexico in Mexico; the grassroots organization Zacahuitzco, in Mexico City, and the farmers markets of the metropolitan area of Vancouver, Canada. The main objective of this study is to recognize, from the perspective of the Conventions theory and the Alternative Rationalities approach, the parallelism, as well as and the differences of this networks in their own unique contexts, in order to deepen conceptualization and theorization on the issue of constructing alternatives in the contemporary agri-food field. The main findings of this research are contradictory: some progresses related to the reconstruction of alternative relationships between small producers and consumers were identified. However, the commercial aspects of the exchange process have become more and more significant, undermining the core values that motivated the emergence of these networks in the first place.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
