Abstract

fetched live from OpenAlex

O objetivo deste trabalho é o de caracterizar a qualidade do meio-ambiente como um bem econômico que tem as particularidades de um bem publico e de uma externalidade. A partir desta constatação, enuncia-se uma série de instrumentos corretivos que permitem obter a eficiência alocativa. A abordagem se refere aos problemas ambientais de uma forma geral, mas é centralizada sobre a qualidade da água. A seção II explicita os aspectos quantitativos e qualitativos do recurso água. Na seção seguinte se caracteriza uma externalidade e um bem público. Esta seção mostra que a qualidade da água apresenta estas características, as quais são fontes de falhas de mercado, como especificado na seção IV. Esta constatação conduz a enunciar na seção V os instrumentos destinados a corrigir tais falhas no quadro dos problemas de qualidade do meio-ambiente.

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.
