Liberated Africans, Slaves, and Convict Labor in the Construction of Rio de Janeiro's Casa de Correção: Atlantic Labor Regimes and Confinement in Brazil's Port City
Bibliographic record
Abstract
Abstract From 1834 to 1850, Latin America's first penitentiary, the Casa de Correção in Rio de Janeiro, was a construction site where slaves, “liberated Africans”, convicts, and unfree workers interacted daily, forged identities, and deployed resistance strategies against the pressures of confinement and the demands of Brazil's eclectic labor regimes. This article examines the utilization of this motley crew of workers, the interactions among “liberated Africans”, slaves, and convict laborers, and the government's intervention between 1848 and 1850 to restrict slave labor at the prison in favor of free waged workers. It asserts that the abolition of the slave trade in 1850 and the subsequent inauguration of the penitentiary augured profound changes in Rio's labor landscape, from a predominantly unfree to a free wage labor force.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
