Abstract
Thresholds, Walls, and Bridges is a collection of essays by historian Dr. Elizabeth Jameson, Imperial Oil-Lincoln McKay Chair in American Studies at the University of Calgary from 1999 to 2017. Together, these essays represent the intellectual evolution of an important and influential scholar told through engaging original research. Thresholds, Walls, and Bridges presents insightful and challenging discussions of historical questions informed by contemporary debates. Ranging from the gold camps of California to northwest Alaska, from North Dakota homesteads of the late 19th century to New Jersey cities of the 1960s, they address the boundaries that divide people and the ways that private acts in everyday lives can make meaningful change. Dr. Jameson explores the histories of borderlands, labour, women, workers, people of colour, and the connected pasts of Canada and the United States. Rejecting approaches that write most people out of history, she makes humanity visible again and again. Thresholds, Walls, and Bridges is a record of a remarkable career.

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.
