Organizations as Brains Learning or Teaching? The key teams in Morgan’s Article - Toward Self Organization are‚ self-organization‚ learning organization‚ holographic organization‚ learning loops‚ cybernetics and information system. All these terms can be generalized in the title of “key features of future organizations”. The main logic of self-organizations is to make scalar chain more flexible. One of the principles of Weberian Ideal Bureaucracy says; “The organization of officers follows

reconfigurable central network oscillator is utilized for autonomous and independent operation of components. Further it favors development of legged robos. The nervous technology provides (1) pulse delay circuits (neurons)‚ interconnected in closed loops‚ which generate square waves and (2) pulse neutralization circuits. The central sequencing network and limb circuits control the direction of the motor thereby the motion of their legs. The advantage is that the use of microprocessors and costly components

tp A new study of Indians’ views of the world shows a large majority continue to rate China and Pakistan as major threats. The report‚ released Monday by the Lowy Institute of International Policy‚ an Australian think tank‚ shows the level of Indian unease about China. More than four-fifths of respondents said they saw the country as a security threat. “The poll reveals multiple reasons for this mistrust‚ including China’s possession of nuclear weapons‚ competition for resources in third
