Abstract

fetched live from OpenAlex

This article examines 9-1-1 call data of the City of Lethbridge in Alberta, Canada over a year to find discernible spatial and temporal trends that may be useful to emergency response or better delivery of emergency management services. The spatial analysis includes Geographic Information Systems hotspot analysis of cellular and landline emergency calls with respect to critical (emergency and healthcare) facilities as well as emergency calls from residential landlines. The temporal analysis looks at hourly, daily, and monthly patterns of emergency calls and the factors driving up the call volumes in certain periods. It also examines emergency call volumes before, during, and after a major disaster (wildfire) event. The article concludes with summarizing the findings and identifying the areas for future research.

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.
