The French Revolution sought to erect an edifice which would bridge the chasm between ancien regime realpolitik and a more idealistic vision of international relations based on natural law. The deputies of the Constituent Assembly, despite their noble intentions, failed to do so. They ended up hurtling into an all-too-familiar vortex, where appeals to natural law hid naked military aggression and strategic egocentrism. Whether this outcome was inevitable or contingent on circumstances continues to pose a dilemma for historical writing on the early Revolution. This article explores the question from the unmined perspective of the foreign Ambassadors resident in Paris during the French Revolution. It uses their unpublished despatches and French police reports to shed new light on the French Revolution's alienation from the international relations system of the ancien regime.  相似文献

This study aims to shed light on Taíno polytheism and its imprint in the Antillean geographic space and the unitary and differentiated development of its religious beliefs and representations, by means of mythic substitution and iconographic hybridisation, as a result of the multinatural perspectivism (animism) shared with its South American relatives and indigenous transculturation processes. It will also show the implications of a revised interpretation of the archaeological heritage based on a comparative approach using the available Caribbean ethnohistoric records (dated from the fifteenth century, mostly, like the mythological passages recorded by friar Ramón Pané) and contemporary lowland Amerindian ethnography along with the iconographic analysis of Taíno imagery in context, an area in which the pioneer linguist José Juan Arrom made the first advances, but his work now demands review.  相似文献

The style of the contemporary German artist Anselm Kiefer is highly innovative and unconventional and is characterized by the use of diverse materials that he selects and combines according to the emotions that they stir in him. The conservation and preservation of works by Kiefer are particularly difficult tasks because of the heterogeneity and, in some cases, the incompatibility of the materials used; therefore, a thorough characterization is crucial before any intervention is considered. In this paper, we report the results of an investigation on a fragment from a multimaterial work and on samples from the paintings Bohemia Lies by the Sea and Die Größe Fracht. The large fragment was cut by the artist himself from a work in progress and is considered destitute of any artistic value; therefore, it was possible to sample it extensively. This fragment and the samples from the Die Größe Fracht and Bohemia Lies by the Sea paintings were analyzed by ultraviolet (UV) fluorescence imaging, fiber optic reflectance spectroscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance, Raman spectroscopy, X-ray diffraction, gas chromatography-mass spectrometry, and pyrolysis gas chromatography-mass spectrometry. This multitechnique approach allowed us to fully characterize and identify pigments, dyes, and organic components that reflect the diversity of the materials typically chosen by the artist. The results are evaluated in the context of the interview that Antonio Rava had with the Anselm Kiefer in 2000.  相似文献

This essay analyzes the history of the Nerve Growth Factor (NGF) discovery, relating some of the principles of the theory of scientific creativity to the cognitive and personal qualities of the scientists that participated in the discovery, particularly Rita Levi-Montalcini and Viktor Hamburger. The discovery of NGF is especially attractive for the history of science as it involves chance, luck, creativity, and some extraordinary scientists.  相似文献

This article proposes to analyse the relationships betweenanthropology andindigenism in Brazil. To do so it considers the migration process of indigenism as a form of knowledge from the Mexican political field to the Brazilian. It affirms that this kind of knowledge had its reception considerably inflected by «traditions of knowledge» for governing populations which developed from colonial sources through time. This analytical perspective is part of an anthropology of colonialism, since it takes as its object Brazilian public administration considering some of its aspects as technologies for the government of multicultural populations.  相似文献

Due to a change in capital funding formula, many school boards across the Province of Ontario engaged in Accommodation Reviews to rationalize the supply of school capacity. This process led to numerous school closures and raised important policy questions regarding the economic value of a school in terms of its capitalization into property values and, by extension, how the closure of a school might affect local neighborhoods. To explore these questions, this research uses spatial hedonic methods to estimate the implicit value of accessibility to schools in the City of Hamilton, Ontario. Spatial Durbin model results provide evidence of a significant negative correlation between distance to schools and housing prices in the Canadian context. This suggests that accessibility to schools is capitalized into property values and that the closure of a neighborhood school may result in potentially significant losses of economic value in communities.  相似文献
