Abstract

fetched live from OpenAlex

In response to the current opioid crisis in Canada, establishing safe injection services (SIS) in high risk communities has become more prevalent. In November 2017, The Trailer opened in Ottawa, Canada and tracks client use, overdose treatment and overdoses reversed. We analyzed data collected between November 2017 and August 2018. During peak hours, demand for services consistently exceeded The Trailer's capacity. Overdoses treated and reversed in this facility increased substantially during this period. Results suggest The Trailer provided an important though not optimal (due to space restrictions) harm reduction service to this high-risk community.

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.
