Walking the talk! Re-invigorating accessible healthy food retail as an anchor of urban livelihood: a shopping list for planners
Bibliographic record
Abstract
Between the 1970s and 2014, Winnipeg experienced dramatic change in the distribution of healthy food retailers in inner-city neighbourhoods. Winnipeg’s “active core” neighbourhoods identified through Dr. David Gordon’s research on Canadian suburbs (Gordon & Jean 2011), have undergone a decline in accessible healthy food options and a rise in food deserts. This practicum identifies the causes of food retail decline and possible strategies for improving accessible healthy food retail options within Winnipeg’s active core. The changes in the distribution of food retail over time in Winnipeg are displayed through a series of maps: one for 1971 and every five years thereafter until 2011, and the year 2014, using data collected through telephone directories. Spatial data of Winnipeg’s active core is compared with population density data, informational maps, and other statistical data. Finally, various stakeholders, including planners, current and former business owners and other experts are interviewed to discuss these trends, lessons learned, and possible solutions.

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.
