Longitudinal study of suomussalmi forestry workers I - Vibrotactile thresholds
Bibliographic record
Abstract
A thirteen-year prospective study of an open cohort of forest workers aimed to report the changes in vibrotactile perception thresholds (VPT) observed at the fingertips of a subgroup of workers who reported for a required annual medical examination on 1990, 1995, and 2003. Vibrotactile thresholds were recorded at the fingertips with the subject seated, and with his forearm supported horizontally in a comfortable position. Skin temperature was recorded at the fingertips before the measurements commenced. and was maintained at ≥27°C. Twenty-eight percent of the study group reported numbness in the hands at study inception, at which time the prevalence reported by the complete cohort was also 28%. The changes in acuity of this finger from 1995 to 2003 are found to have no statistical significance, except at 4 Hz.
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 machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
