A second survey of high explosives traces in public places

This survey was carried out as a follow-up to a 1994 survey carried out by this laboratory (1) in order to determine the background levels of explosives traces in public places. The first survey concentrated on transport areas and police stations in and around London. This second study examines levels in four of the United Kingdom's major cities: Birmingham, Cardiff, Glasgow, and Manchester. Samples were taken at various transport sites and from hotels, private houses, private vehicles, and clothing. The survey showed that traces of the high explosives nitroglycerine (NG), trinitrotoluene (TNT), pentaerythritol tetranitrate (PETN), and cyclotrimethylene trinitramine (RDX) are rare within the general public environment. Only one low-level trace of RDX was detected. NG, possibly associated with the use of firearms, was detected at low levels in two samples and 2,4-DNT was detected in a separate sample. No PETN was detected in any of the samples. The results of the survey indicate that it is unlikely that persons visiting public areas could become significantly contaminated with explosives. The analytical procedures employed would also have detected ethylene glycol dinitrate (EGDN) if present at levels greater than 2 ng, nitrobenzene (NB) if present at levels greater than 50 ng, mononitrotoluenes if present at levels greater than 50 ng, and the other common isomers of dinitrotoluene if these had been present at levels in excess of 10 ng. None of these were detected. The relatively high volatility of EGDN, NB, and the mononitrotoluenes would, however, cause traces of these compounds to disperse rapidly. A proportion of the samples (approximately 7%) were analyzed for the presence of HMX. No HMX was detected.     

Competence, Self-esteem, and Coping Efficacy as Mediators of Ecological Risk and Depressive Symptoms in Urban African American and European American Youth

Structural equation modeling was used to test [Sandler, American Journal of Community Psychology 29: 19–61.] a theoretical model of risk and resilience in an urban sample of African American and European American adolescents. The aims of the present study were to examine whether self-system processes (i.e., competence, self-esteem, and coping efficacy) mediated the relations between ecological risk and depressive symptoms and to determine if pathways varied across ethnic/racial groups. Results implicate self-esteem as a putative mediator of the impact of ecological risk on depressive symptoms for both African American and European American youth. In addition, coping efficacy was a mediator of the link between ecological risk and depressive symptoms for African American youth, but not for European American youth. The evidence supporting competence as a significant mediator of the relation between ecological risk and depressive symptoms was less compelling. Findings suggest substantial similarities in the pathways between ecological risk and depressive symptoms across African American and European American youth.

Perceptions of the criminal justice system by minority and majority group university students: The role of ethnic identity

Minorities are overrepresented in the criminal justice system, and prior research has indicated ethnic minorities and Whites have different opinions of and different experiences within the system. While differences have been shown, the influence of ethnic identity on perceptions of the legal system has been overlooked. The purpose of the present research was to determine if there were differences in perceptions of the legal system by ethnic identity levels for ethnic minorities and Whites. Results indicated differences do exist and ethnic identity is a crucial issue in understanding resonance with the legal system. Future directions for incorporating ethnic identity in research on the criminal justice system are discussed.     

Hidden Law‐Making in the Province of Medical Jurisprudence

Judges articulate their role in controversial cases of medical ethics in terms of deference to Parliament, lest their personal morality be improperly brought to bear. This hides a wide range of law‐making activities, as parliamentary sovereignty is diffused by ‘intermediate law‐makers’, and judicial activity is more subtle than the deference account implies. The nature of litigation raises questions about the contributions of other legal personnel and also the nature of the parties' interests in test‐cases. While judges demonstrate an awareness of some of these issues and anxiety about the constitutional legitimacy of their work, a more nuanced account is needed of their proper role. This may be built on Austin's theory of tacit legislation. It may draw from human rights law. However, considerable work is required before the complexities of hidden law‐making can be properly incorporated into the province of medical jurisprudence.     

Anxiety overflow: Implications of the IVF surrogacy case and the ethical and moral limits of reproductive technologies in Britain

The findings of research into a self-help organisation for surrogacy are discussed. Initial theoretical framework of “medicalisation” changed when no evidence to support cooptation was found. Research into the patterns of development of commercial surrogacy revealed expansion in the 1980s, followed by contraction in the 1990s revealing a lack of consensus within patriarchy regarding its implementation. My explanation for this trend and central thesis is, “anxiety overflow.” Recent trends in the National Health Service (NHS) and decisions by the Human Fertilisation and Embryo Authority are considered, and I suggest that, ethically, morally, and pragmatically, a ceiling has been reached regarding the social acceptability of some contentious technologies. The implications of these findings are used as a backdrop to discuss fears held by some feminists regarding the escalation of techniques used in assisted reproduction.
