Abstract

fetched live from OpenAlex

Within spatial analysis, the decision-making process of individuals involves six interconnected and fundamental elements: current location, destination, distances, and directions, time budgets and type of activity, all of which influence the movement of people in their environment. In this paper we develop a visualization technique allowing for the display of the aggregate travel paths of offenders in order to identify patterns with it. We show that the patterns in the movement for offenders follows that of the major travel routes within the area and is centered in locations of the city-hubs. Results also indicate that significant movement of offenders occur between cities, not just within cities. Consequently, it is shown that urban form and understanding place play a strong role in criminal patterns and offender movement through the city landscape.

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.
