Abstract

fetched live from OpenAlex

Electronic waste (e-waste) is being generated around the globe at a high rate. High market penetration of electrical and electronic equipment (EEE) and the fast development of more innovative designs by producers and manufacturers on a regular basis make the current electrical and electronic equipment obsolete faster than before, which contributes towards the generation of more e-waste. To combat the issue, e-waste management programs are being developed, implemented, or evaluated in many jurisdictions around the world. Ontario is one of the jurisdictions that have taken initiatives and implemented an e-waste management program to address the rising quantity of e-waste. This thesis evaluates the Ontario's e-waste management program by using Logical Framework Approach (LFA) as an evaluation framework, and focusing on the criteria for a normative e-waste management program. It utilizes the Swiss e-waste management program as a case study to provide a comparative analysis, and extract valuable lessons through the application of the lesson-drawing approach that can be applied to improve the effectiveness of the implemented e-waste management program in Ontario.

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.
