The severity of wheat yield crises on eight Spanish farms, 1700-1774
Bibliographic record
Abstract
The main purpose of this article is to measure the severity of the wheat yield crises that occurred during the first three quarters of the 18th century, using records from eight farms and estates in Extremadura, Castile and Andalusia. Specifically, the research is based on account books from several monasteries and the Chapter of the Cordoba Cathedral. We have developed an indicator that considers yield drops in the years of sterility and, where appropriate, the magnitude of cereal deficits during the three-year periods before and after the crises. Our two most relevant conclusions indicate that: 1) the most disastrous cereal crops were obtained in the first quarter of the 18th century; and 2) the decreased severity of the crises in the second and third quarters corresponded more to the mitigation of yield deficits just before and after the years of sterility than to a moderation in their drop during the same periods of scarcity.

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.
