In this study, a new method was developed for the impurity profiling of illicit MDMA tablets. The extraction efficiency, linearity, repeatability and reproducibility of the method were evaluated. Eighty two MDMA tablets coming from presumed unrelated large seizures in 2004 (n >500 tablets) were analyzed by gas chromatography mass spectrometry (GC-MS) in order to assess the discrimination power of the method. The latter was found to be practical, robust, relatively easy to perform, highly discriminative and yielding good chromatography. In addition, some new impurities were detected and identified. Their chemical structures and mass spectra are reported.  相似文献

Within the context of transboundary disputes, this paper seeks to determine which liability concept, negligence or strict liability, performs better when assets are secure against foreign claims for transboundary damages. Our results indicate that, if assets are hidden from foreign claims, strict liability will not implement the socially optimal outcome, but neither will negligence. However, even though the socially optimal outcome is not always achieved, strict liability weakly dominates negligence. These results suggest that the harmonization of statues that deal with transboundary pollution should be based on strict liability not negligence.

We thank two referees for valuable comments that greatly improved the paper and Matt Smith for his research assistance. All remaining errors are our responsibility.  相似文献

This article presents a case study of a project known as 'Designing Better Health Care in the South' that attempted to transform four separately incorporated health services in southern Adelaide into a single regional health service. The project's efforts are examined using Kotter's (1996) model of the preconditions for transformational change in organisations and the areas in which it met or failed to meet these preconditions are analysed, using results from an evaluation that was commenced during the course of the attempted reform. The article provides valuable insights into an attempted major change by four public sector health organisations and the facilitators and barriers to such change. It also examines the way in which forces beyond the control of individual public sector agencies can significantly impact on attempts to implement organisational change in response to an identified need. This case study offers a rare glimpse into the micro detail of health care reform processes that are so widespread in contemporary health services but which are rarely systematically evaluated.  相似文献
