Bibliographic record
Abstract
Curator, researcher, professor, editor, administrator -just a few of the words used to describe Dr. Jon Charles Barlow, an eminent ornithologist whose lengthy careers at the Royal Ontario Museum (ROM) and the University of Toronto (U. of T.) left a lasting impression on the colleagues, students and organizations he was involved with.Jon passed away after succumbing to Alzheimer's disease on 9 February 2009, and left behind significant contributions to the study of ornithology and the museum community.Jon was born in Jacksonville, Illinois in 1935.Growing up in a rural setting instilled in young Jon an interest in all things natural, and his choice of profession reflected that early interest.He attended Knox College in Galesburg, Illinois, for his undergraduate studies, maj oring in Biology and Chemistry.He then migrated west to the University of Kansas for his Master's degree, where his thesis dealt with the "Natural History of the Bell Vireo (Vireo bellii Audubon)."His Ph.D. dissertation at U. Kansas was on the "Ecology and Zoogeography of Uruguayan Mammals."Upon completion of his Ph.D. in 1965, Jon left the US and came to Canada to take up a position as Curator-in-Charge in the Ornithology Department at the Royal Ontario Museum.Under Jon's headship, the Ornithology Department grew in both size and scope.He was a steadfast promoter and supporter of departmental initiatives, and

How this classification was reachedexpand
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.
