Abstract

fetched live from OpenAlex

Étant donné l’absence de politiques publiques précises face au problème de l’insécurité alimentaire des ménages au Canada, les banques alimentaires restent la solution la plus courante, malgré les questions qui se posent au sujet de leur efficacité. En effet, parmi 371 familles à faible revenu de Toronto que nous avons interviewées dans le cadre de cette étude, 75 % avaient vécu de l’insécurité alimentaire, mais seulement 23 % avaient eu recours à une banque alimentaire; et, pour la plupart des utilisateurs de banque alimentaire, l’insécurité alimentaire était un problème chronique grave. Parmi les raisons qui font que les familles vivant de l’insécurité alimentaire n’ont pas recours à une banque alimentaire, notons une certaine réticence à demander la charité, mais aussi un accès difficile à ces banques pour diverses raisons. Ces résultats remettent en question le rôle que les gouvernements fédéral, provinciaux et territoriaux semblent donner aux organismes caritatifs comme moyens de réduire l’insécurité alimentaire, et soulignent la nécessité de politiques publiques claires en cette matière.

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.
