Theoretical and Technical Orientations Toward Longitudinal Research in the Social Sciences
Bibliographic record
Abstract
This paper views life as a developmental process, embedded in a multilevel context. It addresses a number of theoretical, modelling and measurement issues at a relatively abstract level, integrating insights from different disciplines that study developmental processes. At the theoretical level, the usefulness of the life course as an organising principle is discussed. At the analytical level, the main building blocks of the life course are identified, with the life event being the unit of analysis. Each life event has three core aspects: the time at occurrence, the likelihood of occurrence (risk of experiencing the event), and the reason for occurrence. Notions of time, risk, exposure, uncertainty, and interaction are discussed. These basic concepts neatly connect life course theory and life history models.

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.
