The significance of migration
Bibliographic record
Abstract
Throughout history, migration has been intimately related to economic and social development: it is often seen as the result of imbalances in development, but also as influencing development. Assessments of the influence of migration on development have varied over time: sometimes migration has been seen as beneficial and at others detrimental to development, depending on the historical moment and circumstances. With the variation in perspectives has come variation in migration and development policies. In the latter quarter of the twentieth century, the view in Europe shifted from seeing migration as a factor contributing to economic growth in the receiving states and to development in the sending states, to the prevailing view that immigration pressures have reached intolerable levels. More restrictive legislation has been accompanied by tendencies to confuse the status of refugees and illegal migrants and to lump together concerns about security with the problem of asylum seekers. Development and conflict prevention are seen as needed in the migrant-sending countries to curtail unwanted migration. However, while there has been much talk of improving economic and security conditions in source countries – assumed to alleviate migration pressures – so far the emphasis has been on policies aimed at curbing immigration at the destination end – a trend likely to gain momentum in the wake of the events of 11 September 2001.

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.
