Abstract

fetched live from OpenAlex

The economic advantage of constructing and operating large-scale landfills over small-scale landfills has been used to justify regional landfills as the solution to the municipal waste management problem. However, the availability of sufficient landfill capacity will have dampening effects on the social efforts to reduce waste and/or divert waste away from landfills, especially when external costs of landfills are not appropriately reflected in the estimation of total costs. In this study, the negative effects of a landfill that are capitalized in property values of houses located in the proximity of two landfill sites ("Britannia" and "Keele" landfill sites representing a small and a large landfill respectively) in the Greater Toronto Area are examined in a single multiple regression equation. The results indicate that the large landfill has greater adverse impacts than the small landfill on property values. This study suggests further analysis in a model to which more independent variables that explain locational characteristics should be added.

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.
