Abstract

fetched live from OpenAlex

The use of opioids has a global impact on health risk. On the extreme end of the spectrum, some countries are experiencing a serious epidemic of opioid misuse with numerous fatal cases (e.g. in the United States and Canada). The COVID-19 pandemic also altered the pattern of opioid use and its associated health impacts. Understanding opioid usage, problems and associated health effects is crucial for medical treatment and reducing risk because of the inequity of opioid consumption and access globally. Notably, cultural norms and therapeutic approaches differ significantly in East Asian communities with dense populations (such as Hong Kong) from those in European and American countries. Opioid issues and their effects on health risks among these East Asian communities are typically underreported. As a result, this study uses the particular situation in Hong Kong as a case for global comparison.

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.
