Review of analytical techniques for arson residues

Arson is a serious crime that affects society through cost, property damage, and loss of life. It is important that the methods and technologies applied by fire investigators in detection of evidence and subsequent analyses have a high degree of reliability, sensitivity, and be subject to rigorous quality control and assurance. There have been considerable advances in the field of arson investigation since the 1950s. Classification of ignitable liquids has been updated to include many new categories due to developments in the petroleum industry. Techniques such as steam or vacuum distillation and gas chromatography (GC) with flame ionization detection that may have been considered acceptable--even a benchmark--40 years ago, are nowadays generally disfavored, to the extent that their implementation may almost be considered as ignorance in the field. The advent of readily available mass spectrometric techniques has revolutionized the field of fire debris analysis, increasing the degree of sensitivity and discrimination possible considerably. Multi-dimensional GC--particularly GC x GC--while not yet widely applied, is rapidly gaining recognition as an important technique. This comprehensive review focuses on techniques and practices used in fire investigation, from scene investigation to analysis.     

Regional politics: The European union and citizenship

This article examines the development of citizenship within the European Economic Community as a model for citizenship as such, within a global environment. In historical terms, citizenship evolved within the nation‐state, but the nation‐state, which is no longer valid as the exclusive model of economic development, may be inappropriate as a framework for social rights. The fluidity of labour within the European community means that traditional means of political representation within the nation‐state are irrelevant. Within a global context, the economic barriers which are required by nation‐states constitute political barriers to social rights through the vehicle of citizenship. The article considers the European experience of regional politics as lessons for citizenship reform in a global system.

Qualitative Leverage and the Epistemology of Expert Opinion

We discuss the motivation for integrating qualitative informationin statistical models of complex, partially observable causalmechanisms and suggest ways to minimize the dangers posed byBraumoeller and Kirpichevsky. We stress the importance of linkingour statistical estimators to underlying theories of the datagenerating process, qualitative or otherwise.     

SETTING THE SCENE

This article focuses on the Family Law Act of Australia and its subsequent impact on the Australian courts. There is an analysis of the historical and social factors that led to the legislation. The article also discusses the constitutional precedent and framework surrounding the Family Law Act's inception. Finally, the article addresses the future of the Australian courts under the Family Law Act.     

Geoforensic search to crime scene: Remote sensing,geophysics, and dogs

In the absence of surface indications of burial sites, law enforcement or humanitarian organizations are faced with the difficult task of focusing large-scale ground searches to a manageable excavation area. A geoforensic-based survey may exclude parts of the landscape for reasons such as diggability or viewshed analysis but leave areas still too large for invasive exploration. This work examines how drone-based remote sensing, geophysics, and search dogs may be combined to narrow such searches. Here, we ask the reader to consider two examples where forensic geomorphology and land use provided a range of possible burial locations. Following this is a multi-proxy approach to similar dilemma, with a search-to-scene case study using remote sensing (drone photography), geophysics, ground probes, and search dogs. This approach is not presented as a definitive guide, but serves as an example of the conjunctive use of well-studied methods to approach a common problem in geoforensics.     

Characteristics of female patients admitted to an adolescent secure forensic psychiatric hospital

Bluebird House is the only mixed gender NHS secure forensic psychiatric hospital for adolescents in the South of England. It has admitted more than 30 female patients since the service opened in 2008. The admission criteria are that patients must be detained under the Mental Health Act and present evidence of being a risk of harm to others. This article describes the clinical characteristics of 30 consecutive female patients admitted to a highly specialised adolescent forensic inpatient service. Key results include a very high rate of incidents of risk behaviours exhibited by female patients within the unit but good clinical outcomes. The majority of patients had severe symptoms of mental disorder, especially emotional instability, self-harm behaviours and aggressive behaviours. Few had diagnoses of mental illness. Assessment findings from the Millon Adolescent Clinical Inventory and the Structured Assessment of Violence Risk are discussed, as are parallel with studies from other female secure services.     

Tilting at Windmills: the Defamation Act 2013

In April 2013, the Defamation Act was passed, the culmination of a four‐year political campaign. The legislation is intended to ameliorate the ‘chilling effect’ of libel law on scientists, online commentators, NGOs, and others. This paper considers the main changes wrought: reform of the main common law defences, changes relevant to scientific discourse and online speech, and revisions that will impact on process. It identifies areas where there will be problems of interpretation for courts, and suggests that the Act will fail to provide clarity for publishers keen to assess the legality of their actions. The paper also contends that more attention should have been paid to remedies (in particular, the desirability of discursive remedies such as the right of reply). The question is posed whether the Act addresses the core problem with libel law: the juridification and over‐complication of public sphere disputes, and the attendant cost of embroilment in legal proceedings.     

A preliminary investigation into the use of testate amoebae for the discrimination of forensic soil samples

We present the results of an initial investigation into the efficacy of using testate amoebae for the discrimination of soils from wet ground and puddles, as little attention has been given to these organisms in forensic science. The preservation of testate amoebae in these sediments is generally good, although test concentrations are low. Statistical analysis suggests that testate amoebae assemblages are somewhat spatially distinct and have potential to be used for soil discrimination. A case study is presented where mineralogical (X-ray diffraction) and testate amoebae analyses are used in conjunction to clarify the scene of crime in a ‘cold case’ murder enquiry. Testate amoebae were recovered from dried sediment residues on clothing 10 years after the murder. Despite these promising results, further experimental work is crucial to examine the spatial and temporal variation of amoebae assemblages in water films, wet ground and puddles before they can be added to the armoury of methods available to the forensic biologist.
