Dangerous Activities by Children in Grocery Carts: Is Adult Supervision Important?
Bibliographic record
Abstract
Systematic observations of 231 children (infancy to 5 years) and the 231 adults accompanying them were made in 29 supermarkets in Edmonton, Alberta, Canada. The objective of the study was to describe the influence of two indices of adult supervision in supermarkets on children's activities in shopping carts. Adult supervision was measured by whether the adult ever lost sight of the child and whether the adult was 10 feet or more from the child at any time during a shopping trip. 23% of the children stood on the ends or sides of carts; 49% climbed or tried to climb out of carts. Adults lost sight of a child, whether in or outside the cart, a mean of 3.3 times and were 10 feet away 2.7 times during an average shopping trip. Logistic regression showed that a child rather than an adult pushing a shopping cart through the store was the strongest factor related to standing on ends or sides of carts. Pushing by a child was more likely to occur when adult monitoring was low and when children were older. Climbing out was predicted by the number of times an adult was > or = 10 feet away, older children, and a child being in the cart basket as opposed to outside the cart or in the child safety seat.

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.
