Chemical provenance of pre- to post-contact period copper and copper-rich alloy artifacts from archaeological sites in Nova Scotia, Canada : a laser ablation ICP-MS study
Bibliographic record
Abstract
Chemical provenance of pre-to post-contact period copper and copperrich alloy artifacts from archaeological sites in Nova Scotia, Canada: a laser ablation ICP-MS study interesting work for the summer of 2013, as well as for agreeing to convert this study into my undergraduate thesis, and supervise it.Secondly to the Nova Scotia Museum and Cultural Resource Management for allowing us to use their collections, however more specifically: to Dr. Katie Cottreau-Robins, who has worked side by side with me throughout this project from beginning to end, who has shown me that there is more to life than geology, and how great it intertwines with other disciplines.And to Deborah Skilliter, also of the Nova Scotia Museum, for allowing me to access native copper samples in the Museum collections.Thanks must also go to Chris McFarlane of the University of New Brunswick (Fredericton) for introducing me to Laser Ablation, as well as for performing the analyses.
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 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.
