Abstract

fetched live from OpenAlex

Factors that influence women’s perceptions of safety, and how these factors are spatially distributed in Canadian cities, are understudied. This case study determined key factors that affect perception of safety in Halifax, Nova Scotia. A survey asked participants to choose from a list of factors identified in empirical literature those that most positively or negatively affected their perceptions of safety. Media portrayal and stories from friends was a significant negative factor on perceptions of safety; presence of people on the street was the most important positive factor. A weighted multi-criteria analysis (MCA) created a proxy for levels of perceived safety across streetscapes, showing which streets are most likely to be perceived as safe or unsafe by women. Findings suggest that women feel safer when the number of people on the street is increased, which can be achieved through mixed-use areas.

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.
