Abstract

fetched live from OpenAlex

L’efficacité énergétique et les émissions directes de CO2 du mode de transport aérien de passagers sont les plus faibles là où il est en concurrence, c’est-à-dire sur les liaisons terrestres à moyenne distance. Du reste, dans certaines circonstances particulières de remplissage, l’avion n’est pas nécessairement plus polluant que d’autres transports, comme la voiture. Mais le transport aérien dépend d’un produit pétrolier, le kérosène, et il est difficile de lui trouver des substituts. Comment agir face à ces défis ? Le premier type d’action consiste à ne recourir au transport aérien que quand on n’a pas d’alternative crédible et compétitive. La seconde consiste à diminuer les émissions de CO2 des compagnies aériennes, éventuellement même en développant une activité d’opérateur ferroviaire de grande vitesse.

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.
