Use of styryl 11 and STaR 11 for the luminescence enhancement of cyanoacrylate-developed fingermarks in the visible and near-infrared regions

In current casework, most post-cyanoacrylate stains rely on luminescence emission in the visible region (400-700 nm). While traditional stains such as rhodamine 6G work well under most circumstances, some surfaces may generate background luminescence under the same conditions. Detection in the near-infrared region (NIR > 700 nm) has shown to be effective in minimizing the interferences from such surfaces. The laser dye styryl 11 generated strongly luminescent fingermarks when applied after cyanoacrylate fuming on all surfaces tested. When compared to rhodamine 6G, the dye was superior only when viewed in the NIR. Styryl 11 was subsequently combined with rhodamine 6G, and the mixed stain formulation (named StaR 11 by the authors) induced stronger luminescence compared with styryl 11 alone with an ability to visualize in both the visible and NIR regions. Reliable and consistent results were obtained when using either styryl 11 alone or the STaR 11 mixture. The enhancement achieved did not otherwise vary depending on the source of the fingermark secretions. With visualization possible in both the visible and NIR regions, the styryl 11/rhodamine 6G mixture showed significant potential as a post-cyanoacrylate stain.     

Incapacity,the Labour Market and Social Security: Coercion into ‘Positive’ Citizenship

The article examines the likely evolution of the social security system in the United Kingdom in the aftermath of the Welfare Reform Act 2007. This recent legislation is paradigmatic of the new ideology and modes of thought which currently form the foundation of the modern welfare state, an institution increasingly viewed as a facilitator for individual self‐sufficiency, as opposed to its traditional role of providing temporary financial support in periods of need. In addition, it is likely that the Act has promoted at least some changes in the concept of citizenship, in particular the contemporary emphasis on responsibilities as much as on rights. The article considers whether the Act itself has succeeded in meeting the rhetorical claims made for it by legislators during the passage of the Welfare Reform Bill through Parliament. The question of whether the Act contains a punitive or even coercive element is also examined.     

‘That wicked rule,that evil doctrine … ’: Reforming the Law on Disclosure in Insurance Contracts

The Consumer Insurance (Disclosure and Representations) Act 2012, which abolishes the consumer assured's duty to volunteer information, heralds the first successful outcome of the English and Scottish Law Commissions current insurance contract law reform project. This paper outlines the defects of the common law duty of disclosure which the Law Commissions sought to address. It goes on to consider why previous legislative attempts failed, the self‐regulatory measures introduced by the insurance industry as a means of resisting earlier pressure for statutory intervention, and how that resistance broke down. Finally, it examines the scope of the 2012 reforms and the current consultation being undertaken in respect of the duty of disclosure in relation to business insurance. It concludes by assessing the significance of the statute in providing a necessary impetus for future insurance law reforms.     

Screening of gunshot residues using desorption electrospray ionisation-mass spectrometry (DESI-MS)

Several studies have indicated that there are potential environmental sources of particles resembling inorganic primer found in gunshot residues (GSR); as a consequence examiners are reluctant to unambiguously assign the origin of inorganic particles. If organic gunshot residues (OGSR) were found in combination with inorganic particles, the possibility of environmental sources could be potentially eliminated, thereby significantly enhancing the strength of the evidence. Methods have been previously described whereby GSR specimens can be analysed for the presence of OGSR or inorganic GRS (IGSR). However, no methods have been reported that allow the analysis of both OGSR and IGSR on the same specimen. Described in this article is a direct method using desorption electrospray ionisation-mass spectrometry (DESI-MS) for the detection of methyl centralite (MC), ethyl centralite (EC) and diphenylamine (DPA) on adhesive tape GSR stubs typically used for scanning electron microscopy-energy-dispersive X-ray (SEM-EDX) analysis. The optimisation of numerous parameters was conducted using an experimental design. The results indicate that direct analysis of these organic components of GSR is possible although some limitations were also identified. This initial investigation has also indicated that subjecting stubs to DESI analysis does not interfere with subsequent SEM-EDX analysis of primer residues; therefore the technique described herein allows a comprehensive examination of GSR that would be highly probative in the event that both OGSR and IGSR are detected in the same specimen.     

The role of empathy in anger arousal in violent offenders and university students

A lack of empathic responsiveness toward others has been consistently identified as an important antecedent to aggressive behavior and violent crime, with many rehabilitation programs for violent offenders incorporating treatment modules that are specifically designed to increase offender empathy. This study examined the extent to which cognitive (perspective taking) and affective (empathic concern, personal distress) empathy predicted anger in a clinical (male prisoners convicted of a violent offense) and a nonclinical (student) sample. Perspective taking emerged as the strongest predictor of self-reported anger in response to an interpersonal provocation, as well as being most consistently related to scores on measures of general trait anger and methods of anger control. While the relationship between perspective taking and anger was apparent for offenders as well as students, the results did not support the idea that an inability to perspective take is a particular characteristic of violent offenders.     

Developmental incompetence to stand trial in juvenile courts

Juveniles' competency to participate in delinquency proceedings has received increased attention in recent years. Developmental incompetence, whereby juveniles' incompetency is based upon their immaturity, as opposed to a mental disorder or developmental disability, is an evolving and important aspect of this area of law. The following paper reviews theories used to support the notion of developmental incompetence, as well as the extant empirical research on juveniles' competency-related abilities. Using a LexisNexis search, statutory and case laws pertaining to juvenile competency were identified across the 50 states and the District of Columbia. Only six states clearly allow developmental incompetence, whereas 17 have laws that do not include developmental immaturity as an acceptable basis of incompetence in juvenile courts. Developmental incompetence is likely to affect a relatively small proportion of juvenile cases, but has important implications for juvenile forensic practice. Recommendations are offered for forensic practitioners conducting this type of evaluation.
