Abstract

fetched live from OpenAlex

The article assesses the changes in Canada’s food system caused by the COVID-19 pandemic. Though agri-food sector of the country is characterized by a high degree of development, a focus on self-sufficiency in food, and a flexible regulatory system, the pandemic however, as in other countries of the world, has set new challenges for it to provide the population with food. The authors explore the response of elements of Canada’s food system to the problems and challenges of the pandemic. They identified the most vulnerable links in the food supply chain under present circumstances and outlined the reasons for the relative stability of the food system of the country amid the pandemic.

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.
