当代自由主义的困境——论哈耶克、约翰·顿、罗尔斯和罗蒂

非常感谢高瑞泉教授的邀请,使我十分荣幸能有机会来华东师范大学主持第九期大夏讲坛。今天我演讲的题目是“当代自由主义的困境——论哈耶克、约翰&;#183;顿、罗尔斯和罗蒂”。正如在座诸位知道的那样,这个演讲其实是我这次在华东师范大学系列演讲的第三讲。前两讲的题目分别是“人类学文化观念中的知识论意蕴”和“文化观念中的知识论意蕴：中西哲学的讨论”,其出发点就是去探讨如何以哲学思辩的方式来会通中西。     

Linguistic influences on professional communication and recognition: A study of chemists and engineers in two Quebec universities

Linguistic influences on networks of professional communication and recognition among engineers at two Quebec universities were examined. It was hypothesized that chemists and engineers affiliated with the French medium University of Montreal and the Ecole Polytechnique would be less active in research and more likely to obtain scientific recognition locally and to feel professionally unrecognized outside Quebec compared to their colleagues at McGill University. The findings suggest that the localizing effects of using a medium of scientific training which is not the predominant language of international scientific communication and recognition (French) are ambiguous. Although chemists and engineers at the French medium institutions were less active researchers, their language of professional communication with other scientific communities was English and there was little sense of isolation.This research has been supported by grants from the Canadian Council and the Ecole Polytechnique of Montreal. The authors also wish to thank Miss Madeleine Palmer, Miss Daniella Quiniou and Miss Rosalba Casas for their help in data collection for this paper.     

The role of higher education institutions in national development

Abstract from the report of the International Conference on Education (33rd Session) of the International Bureau of Education. It deals with (i) the role of higher education institutions in national development, (ii) improving and sustaining the competence of educators and (iii) managing the system of education.     

Climate control through ionization

This paper summarizes some of the experimental evidence of the apparent biological effects produced by atmospheric ionization. Thermionic ion sources are discussed and the results of experimental determinations of their characteristics are presented.     

Radiation reaction forces and the expanding universe

The expanding universe is described in terms of the known forces of classical physics. It is shown that great clouds of stars are non-conservative systems and that radiation reaction forces play a part in guiding stellar motions. The forces are of importance in unsymmetrical stars and evidence is collected to show that perhaps all stars are possessed of deep seated thermal asymmetries. The forces continually act to increase the mean velocity of the stars and the galaxy is calculated to expand at a rate which closely approximates the observed rate of expansion. From a relation connecting the mean velocity of the stars and their age, it is deduced from the observed motions that the age of the galaxy is about 10¹⁰ years. The deduced rate of expansion of the galaxy agrees well with the observational data and is identical in form and numerical constant with Hubble's relation connecting the velocity of recession and distances of nebulæ.Because of the relative size and spacing of the extra galactic nebulæ and the short time scale it is supposed that the nebulae were formed by fission from a parent-super nebula and this resulted in thermal asymmetries which brought the newly considered forces into action.The resulting expansion was produced by slow evolutionary radiation processes which bear no direct relation to the properties of space or atomic constants.The calculations suggest that in describing the motions of typical stars over long periods of time, radiation reaction forces are as important as the classical gravitational forces.
