Soil vestiges might provide information about a crime scene. The Rietveld method with X‐ray diffraction data (RM‐XRD) is a nondestructive technique that makes it possible to characterize minerals present in the soils. Soil clays from the metropolitan region of Curitiba (Brazil) were submitted to DCB treatment and analyzed using XRD with CuKα radiation in the step‐scan mode (0.02° 2θ/5 s). The GSAS+EXPGUI software was used for RM refinement. The RM‐XRD results, together with the principal component analysis (PCA) (52.6% total variance), showed the kaolinite predominance in most analyzed samples and the highest quartz contents in “site 1.” Higher anatase, and gibbsite and muscovite contents influenced discrimination, mainly in “site 3” and “site 1,” respectively. These results were enough to discriminate clays of four sites and two horizons using a reduced amount of sample showing that the technique can be applied to the investigation into soil vestiges. 相似文献

Between 1988 and 2000, thousands of lives were taken in Algeria at the hands of a violence that sought justification in religion—Islam. While these events can be understood as the direct consequence of decolonization and the bloody Algerian War that lasted eight years, it is important to note that the rise of terrorist violence in Algeria has had consequences beyond its national boundaries. For instance, renowned historian Benjamin Stora has argued that the treatment of Islam in contemporary France appears to have been shaped by the long and bloody conflict that resulted in Algeria obtaining its independence. As Stora points out, “the War with Algeria continues through the struggle against Islam, which today is masked as a fight against Islamic ‘fundamentalism’—a word that is curiously borrowed from vocabulary that is specific to Christianity. The observance of a France that is rooted in the purity of a mythical identity, endlessly threatened, is what legitimizes, a priori, all violence, all measures of ‘war’ in a defense against the ‘invaders.’” 相似文献

The author quotes and briefly analyses a few exerpts taken from textbooks written and printed by Christain missionaries for the Congo primary schools. The Bible story of Cham cursed by his father, told in those texts from which Congolese children learned to read in the first half of the 20th century, stressed the white man’s superiority as coming from God. 相似文献

This study addresses the question of why some countries import more research and development-intensive goods than others. Using a panel data set of 80 countries for the period 1970–1995, results indicate that domestic investment, foreign direct investment and the quality of intellectual property rights systems positively affect technology imports. However, the higher the percentage of the workforce with primary studies, the lower technology imports are. Moreover, intellectual property rights tend to reinforce the positive role played by foreign direct investments in importing technology while the ability of imitation reduces the effect of intellectual property rights. 相似文献

The inefficiency of cooperative agriculture relative to private farms is often attributed to difficulties in monitoring or poor incentives. We develop a model to show that, in technologies with numerous sequential steps, even small shortfalls in worker effort can result in large output declines. Using data on cooperative and private farms in El Salvador, we find greater shortfalls in efficiency between cooperatives and private farms, as well as among cooperatives, for coffee, a crop requiring numerous steps in its cultivation, than for maize and sugar, which require fewer steps. Thus the undersupply of effort in cooperatives may be less than differences in productivity suggest, and cooperative agriculture is most likely to be successful where production does not involve many sequential steps. 相似文献
