Abstract

fetched live from OpenAlex

From its emergence, preimplantation genetic diagnosis (PGD) has been opposed by religious, feminist, and disability-rights advocates. PGD has developed, however, to extend beyond genetic diagnosis of embryos to diagnose chromosomal abnormalities. Evidence shows that PGD is safe, children born after in vitro fertilization (IVF) and PGD having no higher rate of birth defects than children of normal pregnancies. Laws may accommodate PGD directly or indirectly, but some prohibit PGD totally or except to identify sex-linked genetic disorders. When children suffer severe genetic disorders and require stem-cell transplantation, compatible donors may be unavailable. Then, IVF and PGD of resulting embryos may identify some whose gestation and birth would produce unaffected newborns, and placental and cord blood from which stem-cells compatible for implantation in sick siblings can be derived. Ethical issues concern conscientious objection to direct participation, discarding of healthy but unsuitable embryos, and valuing savior siblings in themselves, not just as means to others' ends.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
