Canada Implements Visa Requirement For All Mexican Visitors
Bibliographic record
Abstract
Canada ruffled feathers in Mexico when it decided to require a visa for any Mexican traveling to that country, effective immediately.The Canadian government imposed the requirement on travelers from Mexico and the Czech Republic because of a surge in the number of citizens from the two countries who had requested refugee status in the past few years.There was immediate pressure from some quarters for President Felipe Calderon's administration to respond in kind, but others in Mexico, especially the tourism industry, warned against steps that would curb the number of Canadian visitors to Mexico. Canada trying to stem increase in refugee requestsCanada announced its decision to require visas for Mexican and Czech travelers on July 13, although Canadian Prime Minister Stephen Harper had discussed this possibility with the Calderon administration as far back as November 2008.The Canadian Foreign Affairs Ministry informed Mexican and Czech officials of its decision a few days before the new regulations were put in place.Mexican officials said they immediately expressed their opposition to the Canadian government."We disagreed with this measure," Mexican Foreign Affairs Secretary Patricia Espinosa told reporters.The move would affect tens of thousands of Mexicans who travel to Canada each year.

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.
