The reckoning table, the periodoscope and the shaping of modern pregnancy in nineteenth-century print forms
Bibliographic record
Abstract
How did Victorian print forms shape experiences of pregnancy? This article focuses on pregnancy calendars, a form that rose to prominence in nineteenth-century Britain and Europe. Such calendars appeared in tabular as well as circular formats and were printed in books, periodicals and pocketbooks designed for both medical practitioners and fertile women. These calendars shaped the nebulous period of human gestation, giving pregnancy narrative form by dividing it temporally into stages and highlighting key events and medical interventions. In the nineteenth century, these printed pregnancy calendars mediated between women's personal experiences and gestational body time as well as medical management of that time. During this period, such calendars-which included the columnar reckoning table as well as the circular periodoscope-functioned as instruments of both medical control and female agency. Although they did not enable pregnant women to critique the medicalisation of pregnancy, they nevertheless accorded to such women some power in managing their reproductive bodies.

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.
