Social stratification patterns in adolescents’ active sports participation behaviour: a time trend analysis 1969-1999
Bibliographic record
Abstract
The purpose of this study was to examine (a) whether adolescents’ leisure-time sports participation is socially stratified, and (b) whether possible stratification patterns have changed over the last decades. The population for the study consisted of four random samples of high school boys and girls in Flanders who were exposed to a standardized questionnaire in 1969, 1979, 1989 or 1999. The results indicated that social back ground variables remain relevant to analyse constraints on leisure-time sports participation. Parental sports participation, gender and school programme still deter mine the respondents’ active involvement in sports. The impact of gender and school programme has intensified during the last decade. On the other hand, the adoles cents’ sports participation is no longer correlated with the socioeconomic status of the parents. Some explanations are discussed for linking the adolescents’ sports participation behaviour to the respondents’ social background.

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.
