Abstract

fetched live from OpenAlex

rates in 18th- and 19th-century Sweden with a seven-grade scale over harvest outcomes in the county where the parish was located. We find a Malthusian pattern: a good harvest one year leads to lower death rates, and higher birth and marriage rates, in particular the following year; for death rates there is also an effect in the same year. The effects are large. For example, a crop failure raises the death rate by 15%, and lowers birth and marriage rates by about 10%, in the following year.

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.

Teacher imitation

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.
