Presentation of the 2013 Roebling Medal of the Mineralogical Society of America to Frank C. Hawthorne
Bibliographic record
Abstract
I am pleased to introduce Frank C. Hawthorne as the recipient of the 2013 Roebling medal. Frank is a colleague and friend of some 31 years, someone with whom I have shared a great deal, and someone from whom I have learned a great deal. Frank was an undergraduate in pure geology at the Royal School of Mines, Imperial College, London, and did his Ph.D. in geology at McMaster University. From there, he went to the University of Manitoba for a post-doctoral fellowship in 1973, became a Research Associate in 1975, a federally funded University Research Fellow in 1980, an Associate Professor in 1984, Distinguished Professor in 1997, and was appointed a Canada Research Chair in Crystallography and Mineralogy in 2001, a position that he still holds. I arrived at the University of Manitoba in 1983 to set up the geochemistry laboratories. Frank was responsible for the MAC 5 electron microprobe and had just been awarded funds to buy a single-crystal diffractometer, the first in a geology department in Canada, so we connected quickly over the temperamental behavior of instrumentation and the problems of laboratory space, issues that still concern/annoy us both today. Frank did his Ph.D. on the crystal chemistry of the amphiboles using a combination of single-crystal X-ray and neutron crystal-structure refinement and Mossbauer spectroscopy, and he has maintained an interest in this area through his whole career. In 1983, he began a collaboration with the Crystallography Group in Pavia: Roberta Oberti, Luciano Ungaretti, and Giuseppi Rossi. This led to his spending a total of four years in Italy, the publication of numerous papers on …

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.
