An Examination of Homicide Clearance in Canada
Bibliographic record
Abstract
While there is fear over homicide, crime statistics reveal that homicides are generally on the decline in Canada and have one of the highest clearance rates among other types of crimes (Moreau, 2018). However, recent years also show that unsolved homicide rates are increasing, with no clear explanation behind the recent trends. Studies examining the factors affecting homicide clearance reveal contradictory findings, particularly the role that victim’s characteristics play in homicide clearance. This thesis explores how victim, accused, and situational/incident characteristics affect clearance outcome and the speed in which homicide cases are cleared through using 1991-2015 data from the Homicide Survey. My results indicate that many factors influence homicide clearance, and that victim, accused, and situational/incident characteristics must be considered when examining homicide clearance.

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.
