La diaspora africaine et le Musée Historique National : bilan de près d’un demi-siècle d’expositions (1980-2020)
Bibliographic record
Abstract
Cet article examine la présence de la diaspora africaine dans les expositions de longue durée sur l’histoire du Brésil, montées au Musée Historique National (MHN) entre les années 1980 et 2020. Conjuguant sources institutionnelles et bibliographiques, la recherche montre que, malgré de sérieux efforts, l’expérience afro-diasporique reste encore aujourd’hui passée sous silence et rendue invisible dans les expositions du MHN et dans leurs conceptions du passé. Les sursauts constatés sont en général associés à des dates commémoratives, comme le centenaire de l’abolition de l’esclavage, en 1988. Enfin, d’autres possibilités de lecture des objets afro-diasporiques exposés au musée sont ici proposées, partageant des expériences récentes et indiquant de nouvelles voies d’écriture de l’histoire dans les projets expographiques actuellement menés au sein de l’institution.

How this classification was reachedexpand
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.
