Aggressive pursuit of free trade agreements (FTAs) and customs unions (CUs) by major and minor trading powers alike challenges the conventional wisdom in favor of such pursuit – competitive liberalization. An equally plausible explanation for an active bilateral and regional trade agreement policy, one which effectively de-emphasizes multilateralism, may be competitive imperialism. The protection and enforcement of intellectual property rights is one area in which new provisions, going beyond multilateral rules, are being negotiated and written into FTAs and CUs. Such provisions may yield insights into which characterization of bilateralism and regionalism – competitive liberalization or competitive imperialism – is more apt.

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

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
