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.

Offender assessment and classification is becoming an increasingly important part of correctional supervision and intervention. Over the last several decades, several different methods and “generations” of offender classification have emerged. Of most value appear to be third-generation, actuarial, dynamic risk/need assessments. With any new correctional strategy, however, there is a need to investigate the use of these risk/need assessments on offender subgroups in order to inform issues, such as reliability and prevalence of criminogenic risk factors. The present study utilized data that were gathered using the Level of Service Inventory-Revised (LSI-R). Results and comparisons of these assessments were investigated and presented for Native American and non-Native American offenders as well as male and female offenders. Discussion of the results, implications, and recommendations for further research are presented. 相似文献

This study examines the performance of chief federal prosecutors(U.S. attorneys) and their subsequent careers. In a sample of570 attorneys in office from 1969 to 2000, the length of prisonsentences is positively related to subsequent favorable careeroutcomes for U.S. attorneys. In contrast, conviction rates donot appear to affect the careers of U.S. attorneys. These resultsare consistent with longer total prison sentences beingpersonally beneficial to prosecutors, and prosecutorsmaximizing the length of prison sentences. Overall, the resultssuggest that sentence length, as opposed to convictions rates,is the relevant performance metric. 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

The enzyme activity of phosphoglucomutase (PGM) has been investigated in red cell haemolysates from 142 individuals and compared to the sub-type as determined by isoelectric focusing. The 10 phenotypes showed significant differences in PGM-activity which indicates that there is a correlation between the level of activity and the isolelectric point of homozygotes. No indication of silent alleles or alleles with reduced activity was found in this collective. 相似文献
