This paper describes the French initiative in materials research against both a national and an international background,
in an attempt to disentangle the local circumstances, which prompted this governmental initiative, and to characterize the
specific profile of materials research in France. In presenting a biography of the interdisciplinary program in materials
research (PIRMAT), we argue that: i) the PIRMAT denotes a failure of the French science policy in materials research; ii)
the leadership of the CNRS led to a specific style of research, quite different from the engineering approach of Materials
Science and Engineering, and characteristic of a French style in materials research. 相似文献

In this paper we question whether the radical change in the life situation of people with learning difficulties triggered by the closure of long‐stay hospitals does in fact represent an adequate inclusion into civil society or whether people with learning difficulties continue to experience strong exclusionary tendencies. We will explore the implications of a range of contemporary social justice theories for people with learning difficulties and examine the justice inherent in arrangements for training people with learning difficulties made by Local Enterprise Companies (LECs). We argue that training may be seen as a crucible of social values since its distribution transmits powerful messages about who is considered salvageable or unsalvageable, who is likely to become economically active and who is to be consigned to some special status of otherness. Finally, we consider what conceptualizations of social justice might hold out most hope for people with learning difficulties. 相似文献

Conclusion In this paper we briefly described the current status of research in the field of digital libraries interoperability, mainly
with respect to federated data processing such as permitted within the Open Archive Initiative framework. We then presented
the CERN Document Server Software suite that is a free software package main-tained by CERN providing an online digital library
solution for mid- to large-sized document repositories. The set of CDSware modules was described and the differ-ences with
other existing tools briefly mentioned. Finally we have mentioned a typical usage statistics illustrating the scope of grey
literature and networked con-ditions of the CERN Document Server.
We pointed out that the current trend in grey literature management goes toward institutional repositories build upon the
distributed and federated model. Further research is going on within the CDS collaboration in this area, focused particularly
on (i) semantic interoperability using ontologies in distributed and federated data processing and (ii) ranking technologies
when searching grey literature in OAI compliant repositories. 相似文献

For the last 60 years, varnishes of ancient musical instruments, particularly stringed instruments of the violin family dating 17th and 18th centuries, have been analysed to establish their chemical composition and multi-layered structure. The objective was to rediscover the technology for making the varnish of esteemed Italian violins and to reconstitute it. This paper reviews the physico-chemical studies published on such varnishes and also focuses on a research project carried out since 2002 at the Musée de la musique in Paris. It aims to apply in a comprehensive way different non-destructive or micro destructive methods (Py-GC/MS, IR microscopy, SEM/EDX, EDXRF, synchrotron radiation-based techniques, …) to the study of a large and representative number of ancient varnished musical instruments from a museum collection. 相似文献

Black and white male schoolchildren covertly evaluated their own performance at a verbal task administered by black and white male experimenters. It was hypothesized that academically successful children would be predisposed to appraise themselves favorably, whereas relatively unsuccessful pupils would be biased toward self-criticism. The covert self-evaluations were assumed to represent at internalization of early experiences of predominantly positive or negative social reinforcement from adult socializing agents. The predicition for self-criticism was upheld in the white experimenter condition but not in the black experimenter condition. Relationships consistent with the theory were found between subjects' self-appraisals and their retrospective reports of positive and negative reinforcements received from parents and teachers in various typical situations. These relationships were more evident for black subjects than for white subjects. The extent to which children's self-praise and self-criticism mediated affect was assessed by means of a color conditioning technique. Contrary to predicition, possibly due to the easy nature of the experimental task. 相似文献
