Drawing upon the archival records and publications of the American Federation of Teachers and National Education Association, the following paper argues that the ideological inclinations of union leaders hindered their efforts to protect K-12 public school teachers. The attacks on academic freedom rights during the McCarthy era would thus have implications for years to come in regard to the ability of K-12 teachers to exercise their intellectual autonomy.展开更多

Qualified staff （including teachers and administration） is the necessary condition for high-quality education of students. The qualified staff （university teachers） can only be internationally competitive when they do high quality research andactively participate in the university management. Government and industry set up the ＂boundary conditions＂ for universities, but they should not interfere into the internal self-governance of the universities, and should respect academic freedom. A world-class university has its own Triple Helix uniting education, research and innovation. A few specific examples of practical realization of such ＂sub＂ Triple Helix are given, which are based on personal experience of the author during 24 years of his work as a professor at leading universities in the USA, Germany and Japan. Though some findings and conclusions may have limited use in any particular country, there are universal features that should be present in any modem university interested in increasing its impact on local environment, concerned with interaction to local government and local businesses, and striving for top positions in international rankings.展开更多

The controller was designed to interact from 1 to 6 DOF （degrees of freedom） serial robotic arms, actuated by brushed DC （direct current） servomotors equipped with incremental encoders. Controller architecture is based on four components： a processor, a reconfigurable FPGA （field-programmable gate array）, measurement I/O hardware and software. Functionality of the robotic controller has been proved by means of the interaction with an SCARA （selective compliance assembly robot arm）. The proposed controller presents the potential to teach technical courses （like robotics, control, electronics and programming） and to implement and validate advanced control algorithms.展开更多
