Still three Wales? Social location and electoral behaviour in contemporary Wales

Wales provides a notable exception to the contemporary academic consensus that electoral behaviour is best studied via choice-based approaches. In Wales, the orthodoxy remains that of the Three-Wales Model, an approach formulated in the 1980s which saw voting behaviour as defined by class, language and national identity. This article submits the Three-Wales Model to detailed scrutiny for the first time. The model is argued to have been constructed on a very narrow theoretical basis, and on flawed measurements. Most importantly, however, the Three-Wales Model is shown to have little empirical leverage on voting behaviour in Wales – either for the period when it was formulated or for more recent elections. Factors associated with ‘valence politics’ theories are shown to provide far greater insight into voting behaviour in contemporary Wales.     

Tort Law Culture: Image and Reality

This article highlights two contrasting images of tort. The first reflects the traditional portrayal of justice, depicting tort as an independent ‘natural’ system of rules of universal application forming the foundation of a just society. The second is more recent and relates to the perceived development of a damaging compensation culture. Focusing on personal injury litigation, we show how these portrayals differ from the reality of tort. In practice it is heavily influenced by institutional arrangements: the importance of both welfare provision and liability insurance is highlighted, and the effects of a ‘no‐win no‐fee’ claims market are examined. The operation of tort is very much affected by commercial interests and the economic demands of the institutions which surround it. Overall we conclude that the images of tort fail to reflect how the personal injury compensation system actually operates.     

Concentrations of free-morphine in peripheral blood after recent use of heroin in overdose deaths and in apprehended drivers

The concentration of free-morphine was determined in peripheral (femoral) blood from heroin-related deaths and compared with the concentration in venous blood from impaired drivers. The presence of 6-MAM in blood or urine served as a biomarker for recent use of heroin. Males dominated over females (p<0.001) in both the autopsy cases (88%) and the drivers (91%), although their mean age was about the same 33-35 y (p>0.05). Concentrations of free-morphine in blood were not associated with age of heroin users in Sweden (p>0.05). The median concentration of free-morphine was higher in autopsy cases (0.24 mg/L, N=766) compared with apprehended drivers with 6-MAM in blood (0.15 mg/L, N=124, p<0.05), and appreciably higher than in drivers with 6-MAM in urine but not in blood (0.03 mg/L, N=1823, p<0.001). The free-morphine concentration was above 0.20mg/L in 65% of autopsy cases, 36% of drivers with 6-MAM in blood but only 1.4% of drivers with 6-MAM in urine. Poly-drug deaths had about the same concentrations of free-morphine in blood (0.24 mg/L, N=703) as heroin-only deaths (0.25 mg/L, N=63). The concentration of morphine in drug overdose deaths (median 0.25 mg/L, N=669) was about the same as in traumatic deaths among heroin users (0.23 mg/L, N=97). However, the concentration of morphine was lower when the deceased had consumed alcohol (0.18 mg/L, N=104) compared with taking a benzodiazepine (0.32 mg/L, N=94). The concentration distributions of free-morphine in blood in heroin-related deaths overlapped with the concentrations in impaired drivers, which makes the interpretation of toxicology results difficult without knowledge about tolerance to opiates in any individual case.     

Donor-conceived people's views and experiences of their genetic origins: a critical analysis of the research evidence

This article reports on a systematic review of English language, peer-reviewed publications from 13 empirical studies with donor-conceived children and adults regarding their experiences and perceptions of donor conception. A total of 19 articles that met the inclusion criteria were reviewed. These were identified by means of a bibliographic search of four electronic databases for the period 1990-2011 and supplemented by the authors' personal knowledge of work in this field. No reports from such studies appeared prior to 2000, and more than half have been published since 2008, demonstrating the relative novelty of research in this field. Much of the reviewed research evidence concerns individuals conceived through sperm donation conducted under a regime promoting both anonymity and nondisclosure. Consequently, there is little research that pertains to individuals conceived through other forms of collaborative reproduction, nor to those conceived under arrangements and regimes in which early parental disclosure is both advocated and practised and the identity of the donor and of other genetic relatives may be accessible to donor-conceived individuals. The studies consistently report that most donor-conceived people have an interest in securing information about their genetic and biographical heritage - more information than most of them have been able to obtain. Although a number of methodological limitations in the research base are identified, the authors conclude that the evidence is sufficiently robust to promote the implementation of policies and practices that promote transparency and openness in collaborative reproduction, thus reflecting the importance of maximising future choices and opportunities for donor-conceived people.     

The fallacy of the two-minute acid phosphatase cut off

Research was carried out to determine whether the likelihood of obtaining a positive Acid Phosphatase (AP) test result is affected by the make and type of paper used. Also, we aimed to investigate the frequency of AP positive reactions occurring after 2min using a series of known semen dilutions and to determine whether spermatozoa transfer onto the paper during the act of AP screening. In this research, most brands of paper tested were able to detect a 1 in 40 semen dilution within 2min. Leaving AP test papers for longer will allow the detection of greater dilutions of semen and as the amount of ejaculation is not reliably known in most casework situations and levels of AP activity can vary in different men, this will increase the seminal detection rate in sexual offence allegations.
