Peter Uvin 《Development in Practice》2007,17(4-5):597-606
This article offers an intellectual genealogy of how the concept of human rights has entered the development discourse—from the formulation of a ‘right to development’ to the rhetorical incorporation of rights within prevailing discourse, to the articulation of a ‘rights-based approach’ to development. It concludes with some propositions about the important role that a focus on rights might play in the practice of international development. 相似文献

Toxicologic findings in the USS Iowa disaster. 总被引:5,自引:0,他引:5
The toxicologic results from the 47 victims of the explosion on the USS Iowa are presented. Good correlation between carboxyhemoglobin saturations and cause of death was found. There were no correlations between blood cyanide concentrations and causes of death. Volatile analysis suggested postmortem ethanol production rather than antemortem ethanol ingestion. No drugs except nicotine were detected in any of the victims. 相似文献

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

The legislator, in the German Federal Republic, has opted for a specific legal solution in relation to the protection of the embryo. Carola Müller, in this article, describes this regulation as well as the reasons that have led to its adoption. The article finishes with an exposition of the existing social discussion in German society and the effect that the law has had. 相似文献

This article examines the question of trust in Bosnia and Herzegovina with a special focus on the role of ethnicity. We find generalised trust to be low and declining in Bosnia and Herzegovina. Moreover, generalised trust is negatively affected by the degree of ethnic heterogeneity in the region. However, a further examination of trust reveals a more complex relationship between ethnicity and trust: people tend to show low levels of trust in all other people irrespective of their ethnic belongings. We argue that ethnic distribution might capture some other regional specific characteristics that also affect the level of trust. 相似文献

Fair Trade has become a dynamic and successful dimension of an emerging counter-tendency to the neo-liberal globalisation regime. This study explores some of the dilemmas facing the Fair Trade movement as it seeks to broaden and deepen its impact among the rural poor of Latin America's coffee sector. We argue that the efforts to broaden Fair Trade's economic impact among poor, small-scale producers are creating challenges for deepening the political impact of a movement that is based on social justice and environmental sustainability. The study is based on two years' research and seven case studies of Mexican and Central American small-scale farmer cooperatives producing coffee for the Fair Trade market. 相似文献

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural
trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the
literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among
both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional
framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition
effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural
inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization
and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth
in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization
in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show
the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework
and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental
benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might
reap the environmental benefits of international agricultural trade. 相似文献
