Abstract

fetched live from OpenAlex

Cet article analyse 'l'intrusion logistique' au sein des activités économiques de deux métropoles américaines différentes de par leur histoire, leur taille, leur positionnement géoéconomique : Los Angeles et Atlanta. L’auteur le fait à la fois spatialement et politiquement, en traitant les réactions des divers pouvoirs locaux qui attirent ou repoussent ces activités en croissance. A Los Angeles, aire urbaine de 17 millions d'habitants jouxtant deux ports majeurs, ce sont 1,15 milliard de tonnes de fret qui circulent en 2010, à partir de 7 775 hectares d'espaces d'entrepôts et de distribution, ce qui représente plus du tiers de l'économie métropolitaine. A 50 km du centre, à Moreno Valley, à la différence de Vernon, proche du 'downtown', l'accueil logistique est prioritaire, avec par exemple un bâtiment de 170 000 m2. En Géorgie, à Atlanta, située au croisement de plusieurs réseaux nationaux de transport et qui compte plus de 5 millions d'habitants, le comté de Henry, à 33 km du centre, attire les activités logistiques comme celui de Fulton mais à la différence de celui de Gwinnett. S'il existe des instances de coopération entre les multiples entités territoriales, la concurrence reste vive pour capter la fiscalité spécifique attachée à ces activités.

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.
