The elemental composition of 3,4-methylenedioxymethamphetamine (MDMA) powders and tablets was determined. The objective was the identification of the synthesis method and application of the elemental profile in comparative analysis. The developed analytical method comprised the digestion of a sample followed by quantitative analysis with inductive coupled plasma mass spectrometry (ICP-MS) and inductive coupled plasma atomic emission spectroscopy (ICP-AES). The sample collection consisted of a unique set of MDMA powders (57) from illicit production sites and MDMA tablets (97) taken from large seizures (over 500 tablets) in the Netherlands. The production method of MDMA could be determined for 89 of the 97 tablets. In 84 cases reductive amination using Pt as the catalyst was used, in four cases reductive amination using NaBH(4) or a similar reducing agent was employed and one mixed sample (Pt and B) was found. None of the MDMA tablets were assigned to the aluminium amalgam method. Using the elemental profile, 13 links were identified within the 97 MDMA tablets using cluster analysis based on Pearson correlations. Of these links 10 were corroborated by additional analyses. 相似文献

In December 2005 the first national guideline for palliative sedation in the Netherlands was published. This guideline was developed by a committee of the Royal Dutch Medical Association, at the request of the Dutch government. The guideline defines palliative sedation as 'the intentional lowering of consciousness of a patient in the last phase of his or her life'. According to the guideline the objective of palliative sedation is to relieve suffering, and lowering consciousness is a means to achieve this. It is very important that palliative sedation is given for the right indication, proportionally, and adequately. It is the degree of symptom control, not the level to which consciousness is lowered, which determines the dose and combinations of the sedatives used and duration of treatment. The assessment and decision-making processes must focus on adequate relief of the patient's suffering, so that a peaceful and acceptable situation is created. Palliative sedation is given in the last phase of life, in the imminently dying patient. Palliative sedation raises several legal questions. In this article we describe the structure and contents of the guideline, with special attention for the main legal issues involved, like the distinction between palliative sedation and euthanasia and the process of informed consent. 相似文献

This article discusses one of the most controversial yet importantmodes of liability in international criminal law: joint criminalenterprise (JCE). One such controversy is whether Third CategoryJCE can serve as a basis for genocide convictions. To answerthis question one needs to uncover the nature and origins ofJCE. It is submitted that convictions for genocide based uponthe application of Third Category JCE are justifiable. Thiscontention stems from the premise that JCE is a form of criminalparticipation to which principles of derivative liability apply.However, such an approach is only valid when JCE is strippedto its core and applied as a small-scale group crime, whichrequires proof of a direct link between co-perpetrators. Moreover,in the case of Third Category JCE, a participant should be convictedof participating in genocide, which would carry a lower sentencethan committing genocide as a participant in a First or SecondCategory JCE. 相似文献

Most instruments used to assess offenders' risk of recidivism were developed and validated on male samples. Use of these instruments with female offenders is, however, common practice. This use with female offenders implies the assumption that the risk of recidivism can be predicted on the basis of the same risk factors for women as for men. Yet, this implied gender-neutrality of offender risk instruments has been the topic of much debate. This study compared criminogenic needs in male and female offenders and their relevance in predicting recidivism. A large sample of male and female offenders (N = 16,239) charged with a range of index offenses was studied. Results mainly support the gender neutrality of existing offender risk and needs assessment. However, results do suggest that some criminogenic needs may indeed have a different impact on recidivism for men and women. Problems with accommodation, education and work, and relationships with friends were more strongly correlated to general recidivism in men than in women. For women, difficulties with emotional well-being had a stronger correlation with recidivism than for men. In addition, relative to all other criminogenic needs, problems with emotional well-being were more important for women than for men in predicting general as well as violent recidivism. However, because the bivariate correlation for female offenders between emotional difficulties and recidivism is weak (as it is for male offenders), the question remains whether the relative importance of emotional difficulties in predicting recidivism in women actually has clinical relevance.

Recent trends suggest that cocaine smugglers have become more and more inventive to avoid seizures of large amounts of cocaine transported between countries. We report a case of a mail parcel containing a dance pad which was seized at the Customs Department of Brussels Airport, Belgium. After investigation, the inside of the dance pad was found to contain a thick polymer, which tested positive for cocaine. Analysis was performed using a routine colorimetric swipe test, gas chromatography coupled with mass spectrometry and nuclear magnetic resonance spectroscopy. The polymer was identified as polyvinyl alcohol (PVA) and contained 18% cocaine, corresponding to a street value of € 20,000. Laboratory experiments showed that cocaine could be easily extracted from the PVA matrix. This case report reveals a new smuggling technique for the transportation of large amounts of cocaine from one country to another. 相似文献

Abstract: Two cases are reported from South Australia, where deaths occurred that were due to single self‐inflicted gunshot wounds to the head in individuals who were visiting indoor firearm ranges. Case 1: A 54‐year‐old man visiting an indoor firing range placed a .357 magnum handgun to his head and fired one shot. Case 2: A 23‐year‐old woman who was being instructed in firearm usage at an indoor firing range placed a 9 mm handgun to her head and fired one shot. In both cases, deaths were due to cerebral laceration with skull fracture. Firing ranges may be utilized by individuals who are seeking weapons for suicide attempts, and suicide may be successfully undertaken at such locations even while a victim is under direct supervision. In jurisdictions, where firearm ownership is strictly legislated, it may be that clubs can inadvertently provide access to firearms for this type of activity. 相似文献

Guided by conceptual and empirical work on emerging adulthood, this study investigated the role of closeness to mother and father and behavioral autonomy during adolescence on the development of adult-onset antisocial behavior. Using data from the National Longitudinal Study of Adolescent Health (Add Health), we identified four aggressive (abstainer, adolescent-limited, adult-onset, chronic) and three nonaggressive (adolescent-limited, adult-onset, chronic) trajectories. Members of the aggressive adult-onset trajectory reported higher levels of paternal closeness during adolescence compared to the members of the aggressive chronic trajectory. Maternal closeness and behavioral autonomy did not differentially predict trajectory membership. In addition, members of the adult-onset trajectories were less likely to be employed or in a romantic relationship and reported decreased physical health during emerging adulthood compared to members of all other trajectories. 相似文献

A certain number of single‐vehicle crashes into stationary roadside objects such as trees are thought to be occult suicides. However, is it possible that some cases of multiple deaths within a family in similar crashes are due to unrecognized familial murder‐suicides? A 39‐year‐old woman and her 11‐year‐old daughter are reported who died of injuries following a vehicle impact with a tree. Unusual behavior of the mother leading up to the crash, and assessment at the scene, raised the possibility of this being a nonaccidental event. However, difficulties in retrospectively determining the intent of a driver in a vehicle crash, and the nonrecording of, or lack of separate coding for murder‐suicides on registers, make determination of the incidence of these types of events extremely difficult. It may be that this is a subcategory of murder‐suicide that is underdiagnosed and so is not being registered on central motor vehicle crash databases. 相似文献

This article seeks to understand how reported mediation rates in Chinese courts are produced and what they actually signify. It analyzes data obtained through prolonged fieldwork at a court in central China. The article finds that the court has directly responded to central level mediation incentives by enhancing its overall mediation rate. It has done so strategically by seeking the highest increase using the fullest discretion in the mediation incentive structure and seeking to optimize the highest rate at the lowest cost and risk to the court. This has undermined the objectives of the central level incentives toward mediation, while also drawing the courts' scarce resources away toward unnecessary mediation practices, in part far removed from the courtroom. The article concludes by drawing out broader theoretical conclusions about how information asymmetries, discretion, and goal displacement play out in hierarchical control structures of authoritarian courts. 相似文献
