Measuring neighbourhood change in public space: a public life study in Poblenou, Barcelona
Bibliographic record
Abstract
This research aims to learn if gentrification processes and neighbourhood change might be manifested in observable patterns of public life. Through the systematic observation of pedestrian movement, staying behaviour and other indicators, the study provides a diagnostic of the current conditions in four sites in the Poblenou neighbourhood of Barcelona: the Rambla of Poblenou, Pere IV at Trullàs, Mar Bella beach, and the Superilla. The research team observed public life from 8:00-24:00 hrs during a week in June 2018. The studydoes not find clear evidence of gentrification processes but there are systematic differences across sites. The Rambla performs best overall, with the highest level of pedestrian traffic, afternoon staying behaviour and gender balance. Three of the four sites are gendered spaces, in which men have a disproportionate use of public space. Describing the current patterns of public life may inform urban design interventions and serve as a baseline for long-term studies that aim to measure neighbourhood change.

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.
