Abstract

fetched live from OpenAlex

OBJECTIVE: We investigated the impact of workplace heat and cold on work time loss. METHODS: Field experiments in different industrial sectors were conducted in multiple countries across all seasons between 2016 and 2024. Hundreds of workers were video recorded, and their full shifts (n = 603) were analyzed on a second-by-second basis (n = 16,065,501 seconds). Environmental data were recorded using portable weather stations. The Workplace Environmental Labor Loss (WELL) functions were developed to describe work time loss due to workplace temperature. RESULTS: The WELL functions revealed a U-shaped relationship whereby the least work time loss is observed at 18°C (64°F) and increases for every degree above or below this optimal temperature. CONCLUSIONS: The WELL functions quantify the impact of workplace temperature on work time loss, extending to temperatures previously believed to be unaffected.

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. 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.
