We consider the problem of drawing inferences within a legal framework when a person is a suspect for two separate offences. Although we are primarily concerned with scientific evidence the issue inevitably arises as to how that evidence interacts with other, non-scientific evidence. We show that, in this particular context, the evidence can be conveniently classified into three categories that concern, respectively: the first crime only; the second crime only; and evidence that relates to similarities between the two crimes. Two case examples are considered and we consider DNA, fibres and eyewitness evidence. These are viewed from the perspective of a prosecutor who has to decide whether or not to charge a suspect with one or both crimes. Graphical sensivity analyses are presented which have features that are not intuitively obvious. 相似文献

Although physical punishment has been studied for decades, there are gaps in the literature regarding frequently used form, context, and cross cultural differences. A comparison was made using 227 college students in the United States and Japan, who were presented with four scenarios and surveyed regarding attitudes toward physical punishment, perceptions of appropriate discipline methods, and past experience with physical punishment. Japanese and U.S. respondents reported similar personal experience with physical punishment (Japanese 86%, U.S. 91%). However, U.S. respondents reported a higher likelihood of being hit with an object than did Japanese respondents. For U.S. respondents, the bottom and the hand were the top two sites on the body used for physical punishment, whereas the head and the face were the top two places for the Japanese sample. Unlike U.S. respondents, type of child misbehavior was found to have an impact on Japanese respondents’ views on the appropriate discipline method. 相似文献

This study examined crime and violence against abortion clinics, testing elements of several theories that may help explain the variation of such attacks. The study theoretically and methodologically improved upon the prior research on abortion-related crime and violence. Theoretically, it investigated previously unexamined hypotheses from the social movement literature that may be relevant to this type of behavior. Methodologically, it used more careful measures for several variables, employed unique and heretofore ignored data bases, and examined hundreds of criminal acts across several types of crime (e.g., violence, vandalism, and harassment) directed at abortion clinics. Employing robust logistic regression and correcting for clustering of clinics by state, the study investigated the cross-sectional effects of state-level cultural and structural characteristics on anti-abortion crimes against clinics and staff. Results indicated that some crimes against clinics are more likely in areas where female empowerment is weaker, female victimization is more tolerated, and the anti-abortion movement has failed to reduce abortions. 相似文献

The public's perception of the police is important because it is linked to several important outcomes, including compliance and cooperation with police. Long recognized as being important, research has investigated the factors associated with citizens' evaluations of the police. The way police do their jobs, in addition to what they accomplish, has recently emerged as being a significant determinant of citizens' evaluations of police. What remains largely unexamined is whether this relationship varies across distinct types of contacts between the police and citizens. The current study estimated the effects of citizens' perceptions of procedural justice on overall ratings of officer performance across three types of police–citizen encounters. Results showed that procedurally fair treatment is the most important predictor of citizens' evaluations. 相似文献

In this article a practical case is described when gunshot directions and position of a victim's body at the moment of each shot were determined by natural simulation using an LG-78 laser (made in the form of a gun). 相似文献
