Hierarchical Cluster Analysis of Ignitable Liquids Based on the Total Ion Spectrum

Gas chromatography–mass spectrometry (GC–MS) data of ignitable liquids in the Ignitable Liquids Reference Collection (ILRC) database were processed to obtain 445 total ion spectra (TIS), that is, average mass spectra across the chromatographic profile. Hierarchical cluster analysis, an unsupervised learning technique, was applied to find features useful for classification of ignitable liquids. A combination of the correlation distance and average linkage was utilized for grouping ignitable liquids with similar chemical composition. This study evaluated whether hierarchical cluster analysis of the TIS would cluster together ignitable liquids of the same ASTM class assignment, as designated in the ILRC database. The ignitable liquids clustered based on their chemical composition, and the ignitable liquids within each cluster were predominantly from one ASTM E1618‐11 class. These results reinforce use of the TIS as a tool to aid in forensic fire debris analysis.     

Treating alcohol-related violence: a feasibility study of a randomized controlled trial in prisons

Purpose: There is a lack of good-quality outcome evaluations of interventions for offenders whose crimes are alcohol-related. Randomized controlled trials (RCTs) are considered gold standard in treatment evaluations. Here, we report on a feasibility study for an RCT of an alcohol-related violence intervention, Control of Violence for Angry, Impulsive Drinkers (COVAID). Method: 115 adult male prisoners were randomly allocated to COVAID plus treatment as usual (TAU) or TAU only. Results: Most participants (84%) found COVAID useful. Reconviction data at six months were accessed for 109 (95%) participants. There were no differences between the two groups on violent reconvictions or all reconvictions at the six-month period, but at 17?months the COVAID group had 13% fewer people reconvicted for violence, and 20% fewer had reconvictions for any offence. Conclusion: The results indicate that an RCT is feasible and provides parameters for designing a full RCT. Differences in reconviction between groups favoured COVAID and were clinically important.     

Trauma Characteristics and Posttraumatic Stress Disorder among Adolescent Survivors of Childhood Sexual Abuse

This study examined the relationship between the characteristics of childhood sexual abuse (CSA) and the severity of consequent posttraumatic stress disorder (PTSD), depression, suicidal ideation, and substance use in a sample of 83 female adolescents aged 13–18 years seeking treatment for PTSD. Nearly two-thirds of the sample (60.7 %, n?=?51) reported the perpetrator of the CSA was a relative. A large portion (40.5 %, n?=?34) of the sample reported being victimized once, while almost a quarter of the sample reported chronic victimization (23.8 %, n?=?20). PTSD and depression scores were in the clinical range, whereas reported levels of suicidal ideation and substance use were low. The frequency of victimizations was associated with suicidal ideation. Contrary to expectation, CSA characteristics including trauma type, perpetrator relationship, and duration of abuse were unrelated to PTSD severity, depressive symptoms, or substance abuse.     

Taking Responsibility for Negligence and Non-negligence

Negligence reminds us that we often do and cause things unawares, occasionally with grave results. Given the lack of foresight and intention, some authors argue that people should not be judged culpable for negligence. This paper offers a contrasting view. It argues that gaining control (over our agency, over a risky world) is itself a fundamental responsibility, with both collective and individual elements. The paper underlines both sides, focussing on how they relate as we ascribe responsibility or culpability. Following the introduction, Section 2 (“Culpability and Control: The Negligence Sceptics”) argues that conscious awareness is neither necessary nor sufficient for control. Control is not a property of deliberate choice, so much as a practical achievement. Section 3 (“Non-negligence as a Shared Task”) stresses the collective aspects of non-negligence: creating knowledge about risks, structuring environments to guard against them, and developing standards of care. Failings in the collective task, rather than lack of individual control, mean it can often be unfair to pin culpability on a single individual. Section 4 (“Culpability for Negligence Revisited”) suggests that a basic duty of a responsible person is to acknowledge the ways in which we may do more or less than we mean to, often in ways that create risks. It then sketches an approach to culpability as part of a collective exercise: as we take responsibility for standards of care, and for our own and others’ agency.

     

The No‐men of England: The Geordie Revolt that Defeated the Scotland and Wales Bill in 1977

The Scotland and Wales Acts 1978 failed on multiple criteria. Although devolution of powers to Scotland and Wales was a principal policy of the Labour governments in office from 1974 to 1979, it was defeated in a guillotine vote in 1977. That defeat was orchestrated by the leaders of Tyne & Wear County Council, angry that a government of their own party was apparently neglecting their region in favour of Scotland. The project was rescued in two separate bills, but a further rebel amendment inserted a minimum assent condition in the required referendums. The people of Wales rejected the devolution they were offered. The people of Scotland accepted it, but by a margin that failed to cross the threshold. The resulting vote of confidence brought down the Labour government in March 1979. The role of Tyne & Wear County Council in killing the first bill has never been fully acknowledged. The lessons of the story for current devolution policy are explored. If the UK remains a single country, any policy for tax transfers must be fair to the English as well as to the people of the other three territories.     

Drugs,law, people,place and the state: ongoing regulation,resistance and change

We introduce this special issue firstly by tracing drugs from their traditional, cultural and religious uses through to their roles as commodities in colonial relations and now the global economy. We secondly explore the shifting nature of drugs and drug use in different places and times as shaped by politics, especially state regulation and the law. Thirdly, given the complexity as well as contingency of drugs, we survey a wide range of relevant theoretical approaches, but suggest that a critical analysis attend to their spatial framing and geography. Fourthly, and finally, we summarize the eight papers comprising this collection.
