This applies to manpower as well as other components of policy. A second characteristic of the central bodies is that they perform common functions: establishment of scientific and manpower priorities, financing the operation of research laboratories and utilities, identification of the need for and importance of highly trained manpower, provision of research and fellowship support to individuals, advocating the role of science and technology in the development process, and explaining to the public the importance of science and technology.
