Abstract

fetched live from OpenAlex

Cleaners have been reported to have increased risk for work-related asthma symptoms (WRAS). This study examines whether cleaners have more WRAS compared to other building workers (OBW) and if this can be attributed to frequency of task performances. School board and racetrack workers in Ontario, Canada completed a questionnaire to establish the prevalence of physician-diagnosed asthma (PDA), new-onset asthma (NOA), respiratory symptoms, and WRAS. Among both genders cleaners and OBW had a similar prevalence of PDA, NOA, respiratory symptoms, and WRAS. Female cleaners reported significantly more WRAS. Male cleaners who waxed, and wax stripped floors, spot cleaned carpets, and cleaned tile and grout with a high frequency, reported more WRAS. Time spent performing these tasks was associated with WRAS when they took 4 or more hours. MSDSs for the cleaning chemicals indicate that agents associated with asthma were present suggesting a relationship between task performance and WRAS among male cleaners.

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.
