The Three European-American Countries' Success: How Could Vasectomy Become the Popular Voluntary Choice
Bibliographic record
Abstract
It went through two phases for vasectomy to be widely accepted among men in Canada, United Kingdom and the United States over the past two hundred years in which there were two transitions in the use of contraceptives and two waves of gender equality movements. During the first phase in which the interaction between the first contraceptive transition and the first gender equality movement took place from the end of 18 th to the beginning of 20 th century, men's use of contraception and masculinities went from being in a contradictory relationship to that of integration. Men took contraceptive responsibility by way of traditional means including sexual abstinence and continence. The second phase began in the 1960 s and continues to date. During this period, the second contraceptive transition integrates with the second gender equality movement. Though the governments have not specifically intervened, the availability of high quality medical services enables men to voluntarily take contraceptive responsibilities by choosing vasectomy, and this has become a new characteristic of masculinities.

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.
