Abstract

fetched live from OpenAlex

Vast distances in the Canadian grain handling system means that the supply chain is highly reliant on rail transportation. After years of relative stability, the grain supply chain has recently undergone many signifi cant changes, including deregulation in grain handling. However, the consequences emerging from some of these changes were unexpected. In this paper, we explore the evolving behavior of participants in the increasingly liberalized Canadian grain handling supply chain. The changes seem to be creating new winners and losers in the system. To this end, we fi nd that while current railroad regulations in Canada have led to effi ciencies, deregulation of grain handling seems to have generated gains for grain companies at the expense of farmers.

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.
