Abstract

fetched live from OpenAlex

Cet article traite de l’impact démographique du commerce transatlantique des esclaves sur l’arrière-pays du Golfe du Biafra, et de la répartition à l’intérieur des régions des captifs destinés à l’exportation. Il remet en question le point de vue de Joseph Inikori et Boniface Obichere selon lequel le Middle Belt au nord de la région procurait le plus grand nombre de captifs envoyés en esclavage outre-Atlantique. L’article, s’appuyant sur les journaux de bord de marins, des sources du Nouveaumonde, des échantillons d’exportation, des comptes-rendus ethnographiques, des traditions orales et des données comparatives montre au contraire que Igboland, plus près de la côte procurait le plus grand nombre de captifs destinés par le Biafra à l’exportation. Bien que plusieurs régions d’Igoboland aient souffert de dépopulation en général, la région a conservé de fortes densités parce que sa population s’est maintenue grâce à l’immigration des régions périphériqueset à l’Igboisation des groupes jusque là non Igbo.

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.
