Conclusion Carothers's polymerisation theory, and Flory's enunciation of equal reactivities, were hybrids of ideas, extensions by analogy of the principles and methods of rigorous scientific disciplines into a new field, still in a state of conceptual unclarity. Their hybrid-ideas were radical innovations which contributed towards establishing polymer chemistry as a separate chemical discipline. Joseph Ben-David's theory of hybridisation can cast new light on the social and technological origins of significant innovations in twentieth-century science. Carothers and Flory's enunciations of radically novel ideas were inseperable from their identification with the new role of polymer chemist.Quasi-academic or academically peripheral milieux have had a systematic, indeed historic, role in bringing about innovations in fundamental science, in isolating significant problems and fruitful analogies, and in shaping new types of academic careers. This mechanism at the periphery offsets the pressures for conformity and orthodoxy which otherwise tend to prevail in academic science at the centre. 相似文献

A brief overview of the Bibliographic Access and Control System developed by the Washington University School of Medicine Library is presented. Because the system has been described in two previous reports, this paper focuses on its relationship to other automated programs (i.e., PHILSOM and OCTANET), education of users, evaluation of the system, and outreach to the medical center. In operation for more than two years, BACS represents the computerization of much of the managerial and operational functions of the library, and marks the completion of stage 1 of the three stages of library evolution described in the AAMC report Academic Information in the Academic Health Sciences Center: Roles for the Library in Information Management. 相似文献

An analysis of the image of teachers found in the mass media reveals two conflicting stereotypes. One represents an idealised view of teaching, emphasising teachers’ interaction with individual pupils, the other singles out only the problems faced by the profession, such as personal conflicts, inadequate resources, or the atmosphere of tension and violence in the schools. These two images appear to follow successively in the self‐image teachers hold of their profession. During the course of their careers, they move further away from the idealistic view and adopt a more troubled outlook as they face up to the widening gap between their ideals and the realities of their employment. 相似文献
