Abstract

fetched live from OpenAlex

Abstract Waldinger finds a positive relationship between temperature and city size during the climate change of 1600–1850. We show the main result differs by city size. Cities with less than 1000 inhabitants (which make up 23.5% of observations and are 49.6% of cities at some point) exhibit a strong and positive relationship between temperature and city size, whereas cities with always more than 1000 inhabitants exhibit a negative relationship. Further examination of the underlying city size data, which bins populations into coarse thousand‐wide population intervals, finds the original analysis to be robust to a number of reasonable alternative researcher choices.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
