Savoir-faire et changements techniques dans une entreprise d’ocre en Mauricie, 1892-1968
Bibliographic record
Abstract
Cet article tente de mettre en lumière les dynamismes d'une entreprise d'ocre en Mauricie dont les activités débutent à la fin du XIXe siècle et se maintiennent jusqu'à la fin des années 1960. L'ocre est un mineral utilisé en Europe depuis le milieu du XVIIIe siècle comme pigment d'oxyde de fer dans l'industrie des peintures. L'attention se porte en particulier sur l'entreprise Canada Paint, qui produit des peintures à base d'ocre. Celle-ci, en plus de transformer considérablement le minerai sur place, fit appel à un artisan d'Angleterre spécialisé dans l'industrie des pigments. La place accordée à l'expérience et au savoir-faire d'un artisan jusque dans les années 1960 démontre la persistance d'un système technique qui s'enracine au milieu du XVIIIe siècle et qui ne sera remplacé complètement qu'avec l'avènement des pigments synthétiques.

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.
