Interrogation of short tandem repeats using fluorescent probes and melting curve analysis: A step towards rapid DNA identity screening

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR^® SGM Plus^® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h.     

Financial Compensation for Victims of Catastrophes: A Law and Economics Perspective

This article examines the various approaches legislators may use to compensate victims of catastrophes. Traditional law and economics of insurance literature, with respect to government relief and insurance solutions towards financial compensation, is used to analyze (highly diverging) approaches in Europe and the United States. First, the importance of liability (insurance) is discussed in cases where a liable injurer can be identified; second, the possibilities of first-party insurance are examined, whereby various regulatory solutions (particularly the French model of providing mandatory coverage for catastrophes) is critically discussed. The (first-party) insurance solution is compared with public intervention, and a distinction is made between ad hoc government relief on an ex-post basis and structural compensation funds. The solutions applied and discussed in many countries are critically analyzed for their ability to provide adequate compensation at low costs and their effects on incentives for prevention and for developing private (insurance) solutions.     

Frequency of neck organ fractures in hanging.

This study is a retrospective analysis of 307 accidental and suicidal hangings for the presence or absence of neck organ fractures. Approximately 9% of cases showed such fractures. This is in agreement with one prior study and in disagreement with others. The factor most likely to be predictive of fractures is advanced age. Gender, height of suspension, and ligature type do not seem to be of predictive value.
