Laser desorption/ionization time-of-flight mass spectrometry of triacylglycerols and other components in fingermark samples

The chemical composition of fingermarks could potentially be important for determining investigative leads, placing individuals at the time of a crime, and has applications as biomarkers of disease. Fingermark samples containing triacylglycerols (TAGs) and other components were analyzed using laser desorption/ionization (LDI) time-of-flight mass spectrometry (TOF MS). Only LDI appeared to be useful for this application while conventional matrix-assisted LDI-TOF MS was not. Tandem MS was used to identify/confirm selected TAGs. A limited gender comparison, based on a simple t-distribution and peaks intensities, indicated that two TAGs showed gender specificity at the 95% confidence level and two others at 97.5% confidence. Because gender-related TAGs differences were most often close to the standard deviation of the measurements, the majority of the TAGs showed no gender specificity. Thus, LDI-TOF MS is not a reliable indicator of gender based on fingermark analysis. Cosmetic ingredients present in some samples were identified.     

From ‘Doctor Knows Best’ to Dignity: Placing Adults Who Lack Capacity at the Centre of Decisions About Their Medical Treatment

In 1989, the House of Lords first derived a ‘best interests’ test for the medical treatment of adults who lack capacity from the doctrine of necessity and, now codified, the test continues to apply today. The Mental Capacity Act 2005 sets out a non‐exhaustive checklist of relevant considerations, but it gives no particular priority to the patient's wishes. There is also no formal expectation that the patient will participate directly in any court proceedings in which her best interests are to be determined. This article will consider the advantages and disadvantages of providing additional guidance to decision‐makers in order to help them navigate both taking seriously the wishes of people who lack capacity and, at the same time, not abandoning patients who need help and support. More specifically, this article advocates formalising current best practice in the Court of Protection through the introduction of a series of rebuttable presumptions, or starting points.     

The influence of neuropsychological deficits in early childhood on low self-control and misconduct through early adolescence

Purpose

Gottfredson and Hirschi (1990) contend that low self-control is the result of parental management techniques. However, an emerging line of research has revealed that neuropsychological deficits influence the development of low self-control ( and ). Nevertheless, these studies have largely tested the effects of neuropsychological deficits on low self-control cross-sectionally or in the short term. This study addresses an important void in the literature by examining the influence of neuropsychological deficits in early childhood on levels of self-control and misconduct through early adolescence.

Methods

Data come from the Early Childhood Longitudinal Survey, Kindergarten (ECLS-K), the largest nationally representative sample of U.S. children.

Results

We found that deficits in neuropsychological functioning during kindergarten were consistently predictive of lower levels of self-control during the third, fifth, and eighth grade as well as higher levels of conduct problems during the eighth grade. These effects remained significant after accounting for demographic variables, features of the neighborhood, and a number of parenting variables.

Conclusions

Neuropsychological deficits during early childhood play an important role in the development of low self-control through early adolescence and misconduct during early adolescence.     

Non-normative political extremism: Reclaiming a concept’s analytical utility

ABSTRACT

Political extremism suffers from a definitional deficiency. This article proposes an analytical definition of the term, which avoids using extremism in a pejorative way. This definition also avoids exclusive focus on violence. This definition encourages the analyst to explicitly make the case for defining an action or an actor as extremist by comparing the action or actor to its political context. The article then explores several dimensions of an extremist political identity that can help observers understand extremist behavior and goals. It uses this conceptual framework to consider three examples of political extremism. Finally, the article concludes with some limitations and strengths of this definition of political extremism.     

What price fairness when security is at stake? Police legitimacy in South Africa

The legitimacy of legal authorities – particularly the police – is central to the state's ability to function in a normatively justifiable and effective manner. Studies, mostly conducted in the US and UK, regularly find that procedural justice is the most important antecedent of police legitimacy, with judgments about other aspects of police behavior – notably, about effectiveness – appearing less relevant. But this idea has received only sporadic testing in less cohesive societies where social order is more tenuous, resources to sustain it scarcer, and the position of the police is less secure. This paper considers whether the link between process fairness and legitimacy holds in the challenging context of present day South Africa. In a high crime and socially divided society, do people still emphasize procedural fairness or are they more interested in instrumental effectiveness? How is the legitimacy of the police influenced by the wider problems faced by the South African state? We find procedural fairness judgments play a key role, but also that South Africans place greater emphasis on police effectiveness (and concerns about crime). Police legitimacy is, furthermore, associated with citizens' judgments about the wider success and trustworthiness of the state.     

Establishing the most appropriate databases for addressing source level propositions.

Previous papers in Science & Justice have described the work of the Case Assessment and Interpretation (CAI) project that has been running for several years within the Forensic Science Service (FSS). The principles of the CAI model, which have developed through casework, are the foundation of a balanced, robust and logical approach to interpretation. The question arises frequently as to what is the most appropriate database that should be available to assist in assigning a value to a given probability. In this paper we present a set of guidelines in the form of flowcharts and explore them within the context of a range of case examples.
