Abstract

fetched live from OpenAlex

Up to 50 million metric tones of electronic waste (e-waste) is created annually which consists of the disposal of electronic equipment, including computers, and cellular phones. Most e-waste is processed in developing countries where it is picked through for spare parts or precious metals. These communities are subjected to an array of harsh toxins, including dioxins, PBDEs and heavy metals, which have catastrophic effects on their health. Solutions include minimizing the creation of e-waste, and implementing safe recycling methods. Small changes in our lives could result in saving many communities from the dangers of e-waste across the world.

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.
