Abstract

fetched live from OpenAlex

This paper describes a functional approach to the definition of rural populations for purposes of rural health care research. Rather than define "rural" directly, we created a definition of urban populations and our research target became the non-urban component. Using Geographic Information Systems technology, isochrones (drivetime zones) were created that attached suburban populations to urban centres and mapped non-urban populations into rural hospital catchment areas. For population-based analyses, we have proposed a methodology for constructing catchment areas attached to Rural, Regional and Metropolitan services. We have developed a model for calculation of travel time for patients required to travel for care. We successfully applied these methodologies to the disparate regions of rural Alberta and Northern Ontario in 2 papers that investigated the delivery of rural surgical services. This methodology represents a durable and portable designation of "rural" with potential for research applications in other areas of health research. By defining "urban" rather than "rural," we avoided many of the methodological conundrums in this research field.

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.
