Abstract

fetched live from OpenAlex

Food waste impacts the environment, energy, economy and society. Grocery stores are a powerful link between consumers and farmers. This influential position imparts a huge responsibility on them to reduce food waste. My research question is “How can the grocers in the city of Calgary help reduce food waste?”. National research conducted by the Second Harvest Foundation formed the baseline for the project. Local primary data were collected from the grocery stores through an online survey to find the reasons for food waste and barriers to implementing a food waste reduction strategy. Even though the sample size was small, the comparison with the national survey revealed that the major reasons for food waste are similar locally and nationally. A multifaceted issue like food waste needs collaborative solutions; hence recommendations were included for both the grocers and local government to help reduce food waste and food insecurity in Calgary.

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.
