Food retail and access after the crash: rethinking the food desert problem
Bibliographic record
Abstract
This article reviews Neil Wrigley’s significant contributions to food desert research and how his work informs current debates in the USA around unhealthy foodscapes and what to do about them. After an update on the current U.S. food policy environment, the article reviews the controversies surrounding locating big food retail in underserviced areas. It argues that the food access problem can only move forward if three areas are addressed. First, economic geographers must return to a serious engagement in crucial evidence-based ‘before/after’ retail interventions as Wrigley and his UK researchers did almost 15 years ago. Second, current research must not be done in isolation to the context of the rapidly changing global retail environment and the multiple ways people now access their food. Third, solutions must also address the broader issues of affordability and need and the particular U.S. style governance regime that limits what personal responsibility can do.

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.
