The splintering of the Mercosur following the Brazilian devaluation in early 1999 has given way to an important re-crafting of the regional vision and a significant expansion of the scope of the regional project. This article contends that these trends can best be understood as coalescing into a new (and nascent) form of regionalist governance in the Southern Cone, in which the Mercosur is reconfigured as a vehicle for a new set of developmentalist and strategic objectives. This emerging form of regionalist governance is both causative and indicative of a new political economy both of the subregion and of the wider region of the Americas, and reflective of the crystallisation of a new political economy of development.  相似文献

The Gowers Review of IP was published in early December. Nowthat its contents have been revealed, the IP community in Britainand elsewhere is coming to terms with its contents. Althoughthe Review proposes relatively few changes to the IP systemas we know it, many are wary of its potential impact. One reason for the wariness lies in the approach taken by theReview. The most natural avenue for investigation is that whichtackles IP rights in turn: patents,  相似文献

Measurement variation in the sizing of DNA fragments has been assessed, examining within-gel and between-gel variability. Also, measurement variation detected between two different laboratories, using both manual and automated measurement techniques, has been investigated and discussed.  相似文献

Forty-two insulin-dependent latency and adolescent age diabetics were studied over a four-month period. Half of the population received a multicomponent intervention designed to enhance diabetic regulation. Psychological and demographic variables and glycosylation of hemoglobin were correlated in order to investigate the interaction between personality factors and metabolic control. Number of life event changes predicted initial values of glycohemoglobin, while ego development predicted the magnitude of improved diabetic control.  相似文献

Abstract: A 15‐year‐old male orally consumed an unknown but fatal amount of sustained release hydromorphone. He was naïve to opioid use. No other drugs or alcohol were involved. The cause of death was acute aspiration‐related bronchopneumonia, secondary to hydromorphone ingestion; the manner of death was accidental. Hydromorphone and hydromorphone‐3‐glucuronide were quantified in postmortem fluids by tandem liquid chromatography–mass spectrometry. The hydromorphone concentrations in the peripheral blood, urine, and vitreous humor were 57, 4460, and 31 ng/mL, respectively. The hydromorphone‐3‐glucuronide concentrations in the corresponding three fluids were 459, 36,400, and 40 ng/mL. Hydromorphone‐3‐glucuronide accumulation probably did not contribute significantly to the opiate toxicity. The proposed minimum lethal hydromorphone blood concentration in the nontolerant user is in the vicinity of 60 ng/mL.  相似文献

ABSTRACT

Terrorist group rivalries and alliances have important consequences, but the sources of these relationships are debated. This article offers a side-by-side examination of correlates of terrorist rivalries and alliances. Global analyses of hundreds of terrorist groups find violent rivalry is associated with drug trafficking, state sponsorship, ethnic motivation, and operating in a civil conflict country. Alliances are associated with territorial control, intermediate membership size, and religious motivation. The idea that alliances are an indicator of weakness does not find much support. When relationships are disaggregated into theoretically relevant categories (inter-field and intra-field rivalries, and domestic and international alliances), further distinctions appear.  相似文献
