Forensic utility of the mitochondrial hypervariable region 1 of domestic dogs, in conjunction with breed and geographic information

The 608-bp hypervariable region 1 (HV1) sequences from 36 local dogs were analyzed to characterize the population genetic structure of canid mitochondrial DNA (mtDNA). Sixteen haplotypes were identified. A 417-bp segment of this sequence was compared with GenBank sequences from a geographically representative sample of 201 dogs, two coyotes, and two wolves. Sixty-six haplotypes were identified including 62 found only in domestic dogs. Fourteen of these correspond to the 16 local haplotypes and were among the most frequent haplotypes. The local sample was judged to be representative of the much broader geographic sample. No correlation was observed between local haplotypes and the owner's characterization of dog breed. A 60-bp variation "hotspot" within the canid HV1 was identified as a potentially valuable molecular tool, particularly for assaying limited or degraded DNA samples.     

Using polychromatic X-radiography to examine realistic imitation firearms

Sections 36-41 of the Violent Crimes Reduction Act (2006), which came into force in England and Wales on 1st October 2007, have placed significant restrictions on the sale and possession of 'realistic imitation firearms'. This legislation attempts to produce a definition of a 'realistic imitation' which clearly differentiates these items from other imitation firearms (which are not covered by the legislation). This paper will go a stage further by demonstrating techniques by which blank firing realistic imitation firearms which may be suitable for illegal conversion to fire live rounds may be differentiated from other less 'suitable' (but visually identical) realistic imitations. The article reports on the use of X-radiography, utilizing the bremsstrahlung of a commercial broad spectrum X-ray source, to identify the differences between alloys constituting the barrels of distinct replica and/or blank firing handguns. The resulting pseudo-signatures are transmission spectra over a range from 20 to 75 kV, taken at 1 kV intervals, which are extracted from stacks of registered, field flattened images. It is shown that it is possible to quantify differences between transmission spectra for components of different realistic imitation fire arms, and apply the results to determine the suitability of particular gun barrels from blank firing imitation firearms for illegal conversion to fire live rounds, or related illegal modifications.     

Bloodstain pattern analysis--casework experience

The morphology of bloodstain distribution patterns at the crime scene carries vital information for a reconstruction of the events. Contrary to experimental work, case reports where the reconstruction has been verified have rarely been published. This is the reason why a series of four illustrative cases is presented where bloodstain pattern analysis at the crime scene made a reconstruction of the events possible and where this reconstruction was later verified by a confession of the offender. The cases include various types of bloodstains such as contact and smear stains, drop stains, arterial blood spatter and splash stains from both impact and cast-off pattern. Problems frequently encountered in practical casework are addressed, such as unfavourable environmental conditions or combinations of different bloodstain patterns. It is also demonstrated that the analysis of bloodstain morphology can support individualisation of stains by directing the selection of a limited number of stains from a complex pattern for DNA analysis. The complexity of real situations suggests a step-by-step approach starting with a comprehensive view of the overall picture. This is followed by a differentiation and analysis of single bloodstain patterns and a search for informative details. It is ideal when the expert inspecting the crime scene has also performed the autopsy, but he definitely must have detailed knowledge of the injuries of the deceased/injured and of the possible mechanisms of production.     

The Discourse of Criminality: From Beccaria to Postmodernism

The use of discourse in criminological thought and writing is touted as though it is a recent event; building off the work of postmodernism In reality, however, the use of discourse in addressing criminological concepts goes back to the earliest works in criminology (although it was not referred to as discourse at that time). This article discusses the history of discourse in criminality, focusing specifically on Beccaria and Lombroso. Application for current use of discourse is suggested as a way of making postmodernist writing perhaps more useful to a wider audience. This revised version was published online in July 2006 with corrections to the Cover Date.     

How Can the European Union Contribute to a COP-6 Agreement? An Overview for Policy Makers

During the 6th Conference of Parties (COP-6) in The Hague, the Netherlands, November 2000, crucial progress on a number of outstanding issues related to the Kyoto Protocol will have to be made to open the way for its early ratification, if not to save it from complete failure. Given the present lack of internal US political support for the Kyoto Protocol, the EU may play a pivotal role in making the Kyoto Protocol agreement a reality even without initial ratification of the US, if its able to provide sufficient leadership. In this overview article we discuss the main issues under negotiation, the problems of finding agreement and opportunities for the EU to catalyse a compromise agreement at COP-6, building on key scientific papers as included in this issue and discussions at the European Forum on Integrated Environmental Assessment Climate Policy Workshop in Amsterdam. Key elements are the inclusion of sinks, the use of the Kyoto Protocol mechanisms as a supplement to domestic action and the international compliance system. Domestic implementation of climate policy is a major factor for the EU's credibility.     

Rupture of an intracranial aneurysm--unusual complication of an electric shock.

Here we report about a 35-year-old electrical engineer who was found dead in his study. Postmortem examination revealed that death resulted because of subarachnoid and intraventricular hemorrhage caused by the rupture of an intracranial aneurysm. Right hand and left cheek revealed electrical marks with metallizations on skin, an electric shock was diagnosed to have preceded death. The close temporal correlation suggests that a sudden rise in blood pressure was caused by the electric current and was thus responsible for the rupture of the aneurysm.

Barriers Inhibiting Industry from Partnering with Universities: Evidence from the Advanced Technology Program

This paper describes a small, unique set of project data that was assembled as part of a larger study on universities as research partners. Herein, we summarize, to the extent possible, our interpretation of what the project data reveal about barriers, intellectual property (IP) concerns in particular, inhibiting industry from partnering with universities.     

Financial Literacy and Retirement Planning among Government Officers in Malaysia

ABSTRACT

This study examines the level of financial literacy, financial behaviour and retirement planning behaviour and its dynamics among Malaysian government officers involving 320 employees working in the federal government administrative centre in Putrajaya and Kuala Lumpur using a questionnaire. Findings show high level of financial literacy, good financial behaviour but a mediocre in retirement planning behaviour, and only education and personal income positively influence financial literacy. Age and gender of officers do not influence financial literacy. Furthermore, financial literacy does not correlate with retirement planning and neither does it mediate the relationship between financial behaviour and retirement planning.
