Abstract

fetched live from OpenAlex

ABSTRACT This paper explores the development of the Canadian Water Quality Index (CWQI) from its origins in British Columbia through to the final formulation. The CWQI was adopted in Canada in 2003 by the National Round Table on the Environment and Economy as one of six indicators for reporting on natural capital to Canadians. CWQI values are compared between 2002 and 2022. The trend in water quality between the first year that data were reported for each site and 2022 at 160 sites across southern Canada showed that there was at least some deterioration at 41% of sites, no change at 48% of sites, and an improvement in quality at 11% of the 160 sites.

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.
