<i>MUTUAL SPECIALISATION, SEAPORTS AND THE GEOGRAPHY OF AUTOMOBILE IMPORTS</i>
Bibliographic record
Abstract
ABSTRACT This paper argues for a more actor‐centred approach in freight transportation studies, one that includes freight shippers and public authorities, as well as carriers, and that pays close attention to the relationships between these actors. One advantage of this approach is that it focuses on the conditions under which global logistics flows may become relatively fixed in particular localities. The perspective is illustrated through a discussion of the geography of port usage by importers of automobiles to the US since 1980. The need to secure space at or near marine terminals for vehicle processing activities is a driving factor in port selection. While the overall trade in automobiles has not become concentrated in fewer ports over the last 20 years, individual firms are concentrating the bulk of their import operations in fewer ports. This mutual specialisation involves a process of interpenetration between actors that is only visible in a disaggregated analysis.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
