概要	Repeat victimization analysis studies the sharply elevated short-term risk that the same target — a household, person, or business — is victimized again soon after an initial offense. Established as a crime-prevention priority by Ken Pease, Graham Farrell, and colleagues in the early 1990s, it models the time-course of re-victimization, quantifies how the hazard of a repeat decays as time passes since the first event, and asks whether repeats arise because an event 'boosts' future risk or because stable target features 'flag' that risk.	Routine activity theory explains predatory crime not by the supply of motivated offenders but by the everyday structure of legal activities that brings offenders, targets, and the absence of guardians together in space and time. Proposed by Lawrence Cohen and Marcus Felson in 1979, it argues that crime rates can rise even when offender motivation is constant, because changes in how people work, shop, and spend leisure time alter the opportunities for crime.
