This article considers the claim in the government's White Paper, Justice for All , to put victims and witnesses at the heart of the criminal justice system and argues that there is an unresolved tension within the paper between instrumentalist crime control concerns and intrinsic concerns for the rights of victims and witnesses. It is argued that many of the proposals now contained in the latest Criminal Justice Bill are so preoccupied with rebalancing the system away from offenders that they risk doing injustice to defendants with little tangible benefit to victims and witnesses in terms of rights and remedies.  相似文献

A fatality following ingestion of the drug baclofen (Lioresal) is described. Baclofen was identified in urine by gas chromatography/mass spectrometry. After derivatization with trinitrobenzene sulfonic acid, baclofen was quantitated in serum and urine by high-performance liquid chromatography. The concentration of baclofen was 17 mg/L in serum and 760 mg/L in urine collected approximately 12 h after the overdose. To our knowledge, this is only the second reported fatality involving a baclofen overdose. The previous case did not include quantitation of baclofen in any biological fluid.  相似文献

Between September and December 2005 over 3,000 Sudanese refugees held a sit-in demonstration at the Mustapha Mahmoud Square in Cairo, Egypt, which is located directly across from the offices of the United Nations High Commissioner for Refugees (UNHCR). We analyze the events of the refugee sit-in as an act of global political society, one that saw people outside the realm of the political making demands for recognition and a say in the solutions being developed to relieve their plight. We argue that the sit-in at Cairo was fundamentally a disagreement between the refugees and the UNHCR over the politics of protection, care, and mobility. The article analyzes the strategies through which the refugees named their "population of care" in ways that countered the UNHCR's governmental strategies to classify the Sudanese refugee population in Cairo. We propose the concept of "global political society" as a way of thinking about global political life from the perspective of those who are usually denied the status of political beings. Global political society is a highly ambiguous site where power relations are enacted, taken and retaken by various actors, but in ways that do not foreclose opportunities for refugees to actively reformulate the governmentalities of care and protection.  相似文献

The results of additional validation studies of a sensitive microplate hemagglutination assay for ABO reverse grouping of bloodstains are presented. The results of the validation study demonstrate the reliability of the microplate assay for use in routine serological casework. Based on these studies, the microplate assay has now replaced the Lattes crust test for ABO reverse grouping of bloodstains in the FBI Laboratory.  相似文献

Blood previously acidified with aqueous saturated ammonium chloride solution was extracted with ethyl acetate. The dried extract was subjected to acetonitrile–hexane partition. The acetonitrile portion was analysed for the presence of acidic and neutral drugs by HPLC–DAD (200 mm×2.1 mm I.D. microbore ODS-Hypersil column) and GC–FID (25 m narrow-bore×0.25 mm I.D. HP-5 column with 0.33 μm film thickness). The protocol was found to be suitable for both clinical toxicology (including emergency toxicology) and postmortem toxicology. At least 66 drugs of interest were unequivocally identified by RRTs (HPLC) and UV spectra (DAD) match while another 12 were unequivocally identified by double RRTs match (HPLC and GC). Quantitation was facilitated by incorporating calibration blood standards in each assay batch. The five drugs most commonly encountered in clinical blood specimens (1150 cases) were: paracetamol (47.4% of the cases); chlormezanone (6.6%), theophylline (1.74%), naproxen (1.65%) and mefenamic acid (1.56%). The following drugs were detected in toxicologically significant quantities in postmortem blood specimens (245 cases): phenobarbitone (1.22% of the cases), naproxen (0.82%), chlormezanone (0.82%), theophylline (0.82%), carbamazepine (0.41%) and paracetamol (0.41%).  相似文献
