Abstract

fetched live from OpenAlex

Au cours de la deuxième moitié du XXe siècle, la mortalité aux grands âges (80 ans et plus) s’est singularisée au Canada par son faible niveau eu égard à d’autres pays développés comparables (plusieurs pays européens et le Japon). Une des hypothèses souvent avancées pour expliquer ce phénomène est la sélection d’immigrants en bonne santé, étant donné le rôle important joué par l’immigration dans la croissance de la population canadienne. Bien que la mortalité des immigrants, en particulier celle des immigrants « non européens », soit nettement plus faible que celle des natifs du Canada à tous les âges, le poids de ces immigrants aux âges avancés n’est pas assez important pour expliquer la plus faible mortalité des Canadiens. Il semble bien qu’une combinaison de facteurs, au nombre desquels figurent des conditions de vie plus favorables, soit à l’origine de ce phénomène, qui pourrait cependant disparaître au cours des prochaines années.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
