Abstract

fetched live from OpenAlex

As new projects are being developed in various sectors throughout British Columbia and Canada, there is an increased need to assess how these projects collectively impact the environment.While environmental impact assessment is the process used to analyze and assess the environmental impacts from a single project, cumulative effects assessment (CEA) analyzes and assesses the environmental impacts from multiple projects and activities over space and time.I evaluate the quality of CEA through a case study analysis on the Pacific NorthWest LNG project, using a defined set of best practice criteria for CEA.The evaluation specifically focuses on the assessment of the eight biophysical valued components included in the environmental assessment application for the project.Based on the results of the evaluation, I identify strengths and weaknesses in the CEA and provide recommendations for improvement.

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.
