Logical evaluation of evidence when a person is suspected of committing two separate offences.

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.     

An experimental study of a therapeutic boot camp: Impact on impulses, attitudes and recidivism

Two hundred thirty four adult male inmates entering prison were randomly assigned to an early release program in either a correctional boot camp or a large, traditional prison in the Maryland state correctional system. Boot camp releasees had marginally lower recidivism compared to those released from the traditional prison. A pre-test, post-test self report survey indicated the boot camp program had little impact on criminogenic characteristics except for a lowering of self control. In contrast, inmates in prison became more antisocial, lower in self control, worse in anger management, and reported more criminal tendencies by the end of their time in prison. Criminogenic attitudes and impulses were significantly associated with recidivism. The impact of the boot camp diminished to non-significance when antisocial attitudes or anger management problems were added to the models predicting recidivism. Implications for jurisdictions considering whether to operate correctional boot camps are discussed.     

Long-term success in mediation

This article reports the results of a study of the antecedents of long-term success in community mediation. Seventy-three mediation sessions were recorded and content analyzed. The participants were interviewed at two points: immediately after mediation and 4 to 8 months later. No relationship was found between the quality of the agreements—i.e., the extent to which they solved immediate problems- and long-term success as measured by compliance, improved relations between the parties, and the absence of new problems. On the other hand, joint problem solving by the disputants was related to complainant perceptions of improved relations with the other party. Also respondent perceptions that the mediation had been fair and that all the problems had come out were related to all aspects of long-term success in the eyes of the complainant. The latter results support a procedural justice analysis of mediation and underline the importance of mediator attention to the respondent.     

The legal aspects of corporate computer usage policies

In this paper we examine the legal aspects of corporate computer usage policies including their creation, management, and their relevance to corporate computer forensic investigations. Misuse of corporate computing facilities cannot only lead to a reduction in employee productivity and network bandwidth, but can also increase the risk of infection of such facilities by computer viruses and other malicious code. Moreover, it may lead to the risk of liability and legal action.     

Randomized experiments in criminology: What have we learned in the last two decades?

This paper aims to review randomized experiments in criminology with offending outcomes and reasonably large numbers that were published between 1982 and 2004. A total of 83 experiments are summarized, compared with only 35 published between 1957 and 1981: 12 on policing, 13 on prevention, 14 on corrections, 22 on courts, and 22 on community interventions. Randomized experiments are still relatively uncommon, but there have been more large-scale multi-site experiments and replication programs. There have also been several experiments in which 100 or more places were randomly assigned. Relatively few experiments (only 10 out of 83) were conducted outside the United States. Meta-analyses suggest that prevention methods, correctional therapy, batterer programs, drug courts, juvenile restitution and deterrent policing were effective in reducing offending, while Scared Straight and boot camp programs caused a significant increase in offending.     

From International Sanitary Conventions to Global Health Security: The New International Health Regulations

In May 2005, the World Health Organization adopted the new InternationalHealth Regulations (IHR), which constitute one of the most radicaland far-reaching changes to international law on public healthsince the beginning of international health co-operation inthe mid-nineteenth century. This article comprehensively analysesthe new IHR by examining the history of international law oninfectious disease control, the IHR revision process, the substantivechanges contained in the new IHR and concerns regarding thefuture of the new IHR. The article demonstrates why the newIHR constitute a seminal event in the relationship between internationallaw and public health and send messages about how human societiesshould govern their vulnerabilities to serious, acute diseaseevents in the twenty-first century.     

The use of the laser for determining the direction of the shots and the position of the victim's body in gunshot wounds

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).
