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

This article examines the question of trust in Bosnia and Herzegovina with a special focus on the role of ethnicity. We find generalised trust to be low and declining in Bosnia and Herzegovina. Moreover, generalised trust is negatively affected by the degree of ethnic heterogeneity in the region. However, a further examination of trust reveals a more complex relationship between ethnicity and trust: people tend to show low levels of trust in all other people irrespective of their ethnic belongings. We argue that ethnic distribution might capture some other regional specific characteristics that also affect the level of trust. 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
