A preliminary investigation into the comparison of dissolution/digestion techniques for the chemical characterization of polyurethane foam

Due to their widespread use in domestic and commercial premises, polyurethane foams, as either fragmented or bulk foam, are types of evidence commonly found at crime scenes. The traditional approach to determining the evidential value of polyurethane foam (PF) involves comparing recovered and control fragments under low and high magnification, under various lighting conditions, as well as the comparison of their respective dye spectra. As with most forms of trace evidence, chemical comparison is also desirable. In this work, two approaches to chemically comparing foam fragments were investigated, i.e. inductively coupled plasma–optical emission spectrometry (ICP–OES) analysis of the Tin (Sn) content in different foam types; and gas chromatography–flame ionization detection (GC–FID) analysis of soluble components in PFs mobilized by dichloromethane. Seven different foam types were studied and their Sn content was found to be different. They also produced characteristic GC–FID chromatographic profiles whose compounds were identified with gas chromatography–mass spectrometry (GC–MS) analysis. This study suggests that incorporating chemical data obtained from GC–FID/GC–MS and ICP–OES into a case involving PF could be advantageous, as this will enable the forensic scientist to broaden the comparison between control and recovered fragments, and further assess the strength of the evidence. However, ICP–OES analysis is a destructive technique with a relatively short sample turnaround time, whilst GC–FID analysis is more time-consuming and non-destructive, requiring corroboration with GC–MS data. The values of these two analytical techniques in the forensic chemical characterization of PFs are discussed.     

A Tort-Based Approach to Damages under the Human Rights Act 1998

This article argues that a strong case can be made for departing from the current approach to damages under the Human Rights Act 1998, and for the adoption of an alternative tort-based approach. The article critically analyses the English courts' arguments against adopting a tort-based approach and demonstrates that neither the Act nor the European Convention on Human Rights militate against such approach. It makes a positive case for a tort-based approach, arguing that the law of damages in tort provides an appropriate model for damages under the Act as a matter of principle given the common functions and protected interests that underpin both areas of the law. Further, tort law offers an established and elaborate corpus of principles to draw on, which can readily and naturally be read across to the human rights context. A tort-based approach would also promote consistency across English law, while generally affording greater protection to human rights than the English courts' current approach.     

Critical Stress: Police Officer Religiosity and Coping with Critical Stress Incidents

As a result of exposure to critical stress inducing incidents, police officers experience high rates of family disruption, alcohol abuse, domestic violence, and physical and psychological problems. This paper evaluates the ability of religion to mitigate the harmful consequences of critical stress using data obtained from a survey of metropolitan police officers (n?=?811). Contrary to our expectations, we found less religious officer used more adaptive coping strategies when confronted by critical stress incidents than their more religious counterparts. Furthermore, we found Protestants employed more adaptive strategies than Catholics. Potential explanations for the unexpected findings are discussed.     

Evolutionary psychology and politics

Like its predecessor sociobiology, evolutionary psychology has distanced itself from political discourse. In so far as evolutionary psychology can contribute towards an understanding of politics, it claims to do so only as a potential explanation for political behaviour. However, I argue that evolutionary psychology - like sociobiology - is itself a political phenomenon. It proceeds from a conception of the political - drawn from the Hobbesian social contract tradition - which crucially informs its theoretical trajectory. A recognition of the political character of evolutionary psychology, in this respect, should be the starting point of its critique.
