Geometry based approaches like CrimeStat [7, 3] clusters data based on the geometric location of the points. They exploit a regular geometrical shape like a circle or an ellipse to group high activity areas in domains like crime analysis. CrimeStat uses the K-means [9] and hierarchical nearest neighbour clustering [6] to cluster these activities based on the Euclidean distances between the acti...

This research builds on three decades of effort to produce national estimates of the amount and rate of force used by law enforcement officers in the United States. Prior efforts to produce national estimates have suffered from poor and inconsistent measurements of force, small and unrepresentative samples, low survey and/or item response rates, and disparate reporting of rates of force. The pr...

Analysis of wastewater with an aim of community-wide estimation of drug use is a new and very promising approach. Until now it was very difficult to determine if mass loads of studied drugs were actually originating from consumption, or disposal of unused drugs or production waste. This uncertainty in the estimation of community wide drugs use should not be underestimated. This paper aims to ap...

Studies assessing the impact of epilepsy and its medication on the risk of road traffic crashes have shown inconsistent results. The aim in this study was to assess this risk using French databases. Data from three French national databases were extracted and matched: the national health care insurance database, police reports, and the national police database of injurious crashes. Only antiepi...

Fear of violent crime is greater today than in recent memory. So too are Australian police statistics on the incidence of violent crime. The interpretation of crime statistics and of public attitudes should, however, be undertaken with care. Even before this year’s tragic massacre at Port Arthur, most Australians had formed the impression that violence in our society had reached unprecedented l...
