Abstract

fetched live from OpenAlex

Despite being a catalyst for progress, Materials Science and Engineering is relatively unknown as an undergraduate discipline in the UK. By analysing UK data published by the Universities and Colleges Admissions System (UCAS) and the United Kingdom's Higher Education Statistics Agency (HESA), we explore how applications to study and uptake of Materials Science and Engineering differs from other related disciplines in the United Kingdom. We find Materials Science and Engineering lags significantly behind related disciplines in terms of applications, and this is likely to have ramifications on the diversity of our student population. We also find a significant number of students is likely to join a Materials Science and Engineering programme by an internal transfer process rather than by direct application. Our analysis suggests higher education institutions should ensure Materials Science and Engineering is defined well as a discipline, both in marketing materials and by consistently using the Higher Education Classification of Subjects (HECoS) coding system.

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.

Not 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.
