Arsenic speciation of two specimens of Napoleon's hair

Since 1960, it has been demonstrated by various analytical procedures that high concentrations of arsenic were present in Napoleon's hair. Various authors, indicating that the detected arsenic levels are a consequence of external contamination, have challenged the results of these examinations. We have tested two strands of hair, referenced as Noverraz and Grand Maréchal Bertrand. Samples were incubated 6 h in water at 90 °C, and arsenic speciation was carried out by HPLC–ICP/MS. The residue was injected on a cation-exchange PRP-X200 column that allows the detection of arsenobetaine and on an anion-exchange PRP-X100 column to test for the mineral forms. In these conditions, the inorganic species As(III), As(V) and their metabolites (DMA and MMA) were separated. Analysis of hair samples highlighted massive amounts of total arsenic (42.1 and 37.4 ng/mg). Arsenical species found in the two samples of analyzed hair are distributed in the following: As(III) 31.1 and 44.7%; As(V) 66.3 and 53.2%; DMA 0.42 and 0.15%. Traces of MMA were detected, and 2% of the species could not be identified. These results prove that more than 97% of the arsenic found in the hair of Napoleon is in inorganic form, which is consistent with a chronic intoxication to arsenic.     

Posttraumatic Stress Disorder: Current Concepts and Controversies

The diagnosis of posttraumatic stress disorder (PTSD) sometimes is raised in compensation claims, in tort settings, and in other medical–legal settings. Accordingly, health-care and legal professionals working in these areas need to be familiar with the current findings and controversies concerning the disorder. The purpose of this article is twofold. First, we review the most important findings concerning the clinical features, etiology, and treatment of PTSD. Second, we examine six major controversies concerning the disorder that are relevant to psychologists and other medical–legal practitioners: (a) the issue of what qualifies as a traumatic stressor, (b) the question of whether traumatic stress causes brain damage, (c) the validity of the concept of delayed-onset PTSD, (d) the recovered memory controversy, (e) the question of whether PTSD can arise when the person has no memory of the trauma (e.g., due to concussion), and (f) issues concerning PTSD malingering. Throughout this article we offer recommendations for psychological and other medical–legal practice in relation to the evaluation of PTSD claims.     

Business Representation in the UK Since 1979: the Case of Trade Associations

The article explores the impact of Conservative governments since 1979 on business representation. It concentrates on the trade association—the most common form of business organization in the UK but one which has been largely neglected in the discussion of business representation. The results of a major survey of trade associations conducted in 1994 are reported and their significance assessed in the light of three general propositions about the direction of business representation since 1979.     

Stressors, coping resources and strategies, and police stress in South Korea

The present article extends prior research to identify the predictors of police stress from work place problems, the resources available through social support, different strategies for coping with stress, and conditions unique to policing in South Korea. The unique conditions are perceived public perception of police and attitudes towards women working outside of the home. Seven hundred officers were asked to participate in the research, and 686 did participate (96 percent response rate). Almost half of the variance in stress could be explained. Reports of being ridiculed and “set up” in dangerous situations, and to a lesser extent, lack of support from superiors and perceived disrespect from the public, were salient predictors of stress. Coping strategies did not moderate the associations between stressors and stress. Findings were interpreted in relation to collectivist culture and possible points of intervention.
