Determining the order of deposition of natural latent fingerprints and laser printed ink using chemical mapping with secondary ion mass spectrometry

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) chemical mapping was used to investigate the order of deposition of natural latent fingerprints and laser printed ink on paper. This feasibility study shows that sodium, potassium and C₃H₅ positive ions were particularly abundant endogenous components of the natural fingerprints and also present in the paper examined, but were mostly absent in the laser printed ink. Mapping of these ions enables the observation of friction ridges from latent prints on the ink surface, only when a fingerprint was deposited above the layer of ink. As a demonstration of proof of concept, blind testing of 21 samples from three donors resulted in a 100% success rate. The sensitivity of this technique was investigated within this trial through the examination of up to fifth depletion fingerprints and ageing of up to 28 days. Migration of fingerprint and paper components to the ink surface, although observed with increased ageing time, was not found to compromise determination of the deposition sequence.     

Penal abolitionism: a different kind of reform

Rates of reoffending are high, both for people leaving prison and people on community sentences: the reconviction rate for all custodial sentences is 46.8 per cent, rising to 56.8 per cent for custodial sentences less than one year in duration. The reconviction rate for Community Orders is 36.8 per cent (Ministry of Justice, 2011).

Reoffending is expensive. Prison costs £45,000 per prisoner per year, plus £170,000 to build and maintain each new place (Prison Reform Trust, 2010). Cheaper community sentences can still cost £4,200 per offender per year. Many people in the criminal justice system have multiple and complex needs. For example, 72 per cent of male and 70 per cent of female sentenced prisoners suffer from two or more mental health disorders (ibid).     

Moral judgement,cognitive distortions and empathy in incarcerated delinquent and community control adolescents

Abstract

Immature moral judgements, cognitive distortions and low empathy could contribute to criminal offending and are often targeted in interventions aimed at reducing risk of recidivism. We compared 58 delinquent 13–18-year-olds, incarcerated in youth homes in Sweden (29 males, 29 females) with 58 (29 males, 29 females) community control adolescents individually matched on age, gender, ethnicity and socio-economic position. Self-report questionnaires examined moral judgement, cognitive distortions, and empathy. Delinquent adolescents exhibited less mature moral judgements and more cognitive distortions than control adolescents. However, no association between delinquency status and self-reported empathy was found. In addition, girls reported more mature moral judgements, less cognitive distortions and more empathy than boys did. Moral judgement and empathy were positively correlated and both measures were negatively correlated with cognitive distortions. Our data support the idea that moral judgement and cognitive distortions are important treatment targets for juvenile delinquents, whereas empathy may be less meaningful to address directly.     

Offenders' lies and truths: an evaluation of the Supreme Court of Sweden's criteria for credibility assessment

Abstract

The criteria used by Swedish courts for assessing credibility of plaintiffs' accounts were for the first time scientifically evaluated. Furthermore, unlike much previous deception detection research, we used offenders as participants instead of college students. False and truthful confessions by 30 offenders were analysed, and few significant effects were obtained. Truthful confessions were rated as having a higher degree of clarity than false confessions. Women's truthful confessions were rated as more credible than their false confessions. The offenders who were most experienced in being interviewed by the police gave a stronger impression of talking about something self-experienced in their false than in their truthful confessions; hence, it seems that offenders with more police interview experience have developed a kind of expertise in telling a convincing lie about crime. Overall, the criteria for credibility assessment used by Swedish courts had very limited usefulness in discriminating truthful and false confessions. A critique of the current status of evaluating statements in Swedish courts is provided.     

Rationalism in Public Law

Rationalism is ‘the stylistic criterion of all respectable politics’. So lamented political philosopher Michael Oakeshott in a series of essays published in the 1940s and 1950s. Rationalism, for Oakeshott, is shorthand for a propensity to prioritise the universal over the local, the uniform over the particular and, ultimately, principle over practice. It culminates in the triumph of abstract principles over practical knowledge in a manner that erodes our ability to engage in political activity. Although Oakeshott's critique was made with the practice and study of politics in mind, it has a wider relevance. Rationalism, as we see it, has become the dominant style in public law. We draw upon Oakeshott's critique to elucidate the risks associated with rationalism in public law and call for a renewed engagement with practical knowledge in the study of the constitution.     

A Comparison of Enhancement Techniques for Footwear Impressions on Dark and Patterned Fabrics,

The use of chemical enhancement techniques on porous substrates, such as fabrics, poses several challenges predominantly due to the occurrence of background staining and diffusion as well as visualization difficulties. A range of readily available chemical and lighting techniques were utilized to enhance footwear impressions made in blood, soil, and urine on dark and patterned fabrics. Footwear impressions were all prepared at a set force using a specifically built footwear rig. In most cases, results demonstrated that fluorescent chemical techniques were required for visualization as nonfluorescent techniques provided little or no contrast with the background. Occasionally, this contrast was improved by oblique lighting. Successful results were obtained for the enhancement of footwear impressions in blood; however, the enhancement of footwear impressions in urine and soil on dark and patterned fabrics was much more limited. The results demonstrate that visualization and fluorescent enhancement on porous substrates such as fabrics is possible.     

Odontological Approach to Sexual Dimorphism in Southeastern France

Abstract: The aim of this study was to establish a prediction formula to allow for the determination of sex among the southeastern French population using dental measurements. The sample consisted of 105 individuals (57 males and 48 females, aged between 18 and 25 years). Dental measurements were calculated using Euclidean distances, in three‐dimensional space, from point coordinates obtained by a Microscribe. A multiple logistic regression analysis was performed to establish the prediction formula. Among 12 selected dental distances, a stepwise logistic regression analysis highlighted the two most significant discriminate predictors of sex: one located at the mandible and the other at the maxilla. A cutpoint was proposed to prediction of true sex. The prediction formula was then tested on a validation sample (20 males and 34 females, aged between 18 and 62 years and with a history of orthodontics or restorative care) to evaluate the accuracy of the method.     

Through the meshes of patriarchy:

This article offers an analysis of women's life and status within the peasant family of the Saguenay region (Quebec) prior to the completion of the settlement process. After a brief survey of the literature in the field, a variety of sources (including several bodies of oral data) is analyzed, offering the conclusions that: (1) it is useful to carefully distinguish between the macro-social or societal level (State, Church, capital …) and the micro-social sphere of the family and the conjugal couple; (2) the societal scale was made up of unambiguously patriarchal powers, norms, and institutions, whereas at the micro-social level, the reality was much more complex and offered a great deal of diversity; (3) societal constraints heavily influenced the conjugal relationship but not in a deterministic way. The latter remained a social area where the women, somehow, remained able to maneuver, to negotiate and to assert themselves; (4) the same can be said of the thesis that male ownership and control of the means of production necessarily entailed subordination and proletarianization of the married women; and (5) it would be fruitful to explore the idea that male domination was mostly rooted and secured not in the family but in the societal arena.
