Abstract

fetched live from OpenAlex

The Fraser River Port Authority dredges the Fraser River to maintain navigation in support of the port activities. Sales of the dredged river sand are the only source of revenue offsetting the cost of dredging. The Port Authority does not have the key success factors to compete in the sand market. The burden of dredging impedes the economic development of the Fraser River Port. The Port Authority can change the status quo by extracting more value from the dredged river sand, implementing a user-pay system, reducing the scope of dredging, or obtaining government funding for dredging. The goals for the dredging program are efficient use of resources, equitable distribution of costs and benefits, no negative net impact on the environment, and acceptability to stakeholders. The analysis recommends that the Port Authority extract more value from the dredged material by utilizing it in land reclamation projects.

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.
