MCQ-> Thought the Cold War has ended selective tactics are still continuing for ensuring the military and economic dominance of developed countries Various types of technology denial regimes are still being enforced which are now being mainly targeted against developing countries like India Today we in India encounter twin problems On one side there is a large scale strengthening of our neighbours through supply of arms and clandestine support to their nuclear and missile programmes and on the other side all efforts are being made to weaken our indigenous technology growth through control regimes and dumping of low-tech system accompanied with high commercial pitch in critical areas Growth of indigenous technology and self-reliance are the only answer to the problem Thus in the environment around India the number of missiles and nuclear powers are continuously increasing and destructive weapons continue to pile up around us in spite of arms reduction treaties To understand the implications of various types of warfare that may affect us we need to take a quick look at the evolution of war weaponry and the types of warfare I am highlighting this point for the reason that in less than a century we could see change in the nature of warfare and its effects of society In early years of human history it was mostly direct human warfare During the twentieth century up to about 1990 the warfare was weapon driven The weapons used were guns tanks aircraft ships submarines and the nuclear weapons deployed on land/sea/air and also reconnaissance spacecraft. Proliferation of conventional nuclear and biological weapons was at a peak owing to the competition between the superpowers The next phase in a new form has just started from 1990 onwards The world has graduated into economic warfare.The means used is control of market forces through high technology.The participating nations apart from the USA, are Japan the UK France Germany certain South East Asian countries and a few others The driving force is the generation of wealth with certain types of economic doctrine The urgent issue we need to address collectively as a nation is how do we handle the tactics of economic and military dominance in this new form coming from the backdoor ? Today technology is the main driver of economic development at the national level Therefore we have to develop indigenous technologies to enhance our competitive edge and to generate national wealth in all segments of economy Therefore the need of the hour is arm India with technology.Why do certain countries use selective tactics against developing countries ?

MCQ-> Recently I spent several hours sitting under a tree in my garden with the social anthropologist William Ury, a Harvard University professor who specializes in the art of negotiation and wrote the bestselling book, Getting to Yes. He captivated me with his theory that tribalism protects people from their fear of rapid change. He explained that the pillars of tribalism that humans rely on for security would always counter any significant cultural or social change. In this way, he said, change is never allowed to happen too fast. Technology, for example, is a pillar of society. Ury believes that every time technology moves in a new or radical direction, another pillar such as religion or nationalism will grow stronger in effect, the traditional and familiar will assume greater importance to compensate for the new and untested. In this manner, human tribes avoid rapid change that leaves people insecure and frightened.But we have all heard that nothing is as permanent as change. Nothing is guaranteed. Pithy expressions, to be sure, but no more than cliches. As Ury says, people don’t live that way from day-to-day. On the contrary, they actively seek certainty and stability. They want to know they will be safe.Even so we scare ourselves constantly with the idea of change. An IBM CEO once said: ‘We only re-structure for a good reason, and if we haven’t re-structured in a while, that’s a good reason.’ We are scared that competitors, technology and the consumer will put us Out of business — so we have to change all the time just to stay alive. But if we asked our fathers and grandfathers, would they have said that they lived in a period of little change? Structure may not have changed much. It may just be the speed with which we do things.Change is over-rated, anyway, consider the automobile. It’s an especially valuable example, because the auto industry has spent tens of billions of dollars on research and product development in the last 100 years. Henry Ford’s first car had a metal chassis with an internal combustion, gasoline-powered engine, four wheels with rubber types, a foot operated clutch assembly and brake system, a steering wheel, and four seats, and it could safely do 1 8 miles per hour. A hundred years and tens of thousands of research hours later, we drive cars with a metal chassis with an internal combustion, gasoline-powered engine, four wheels with rubber tyres a foot operated clutch assembly and brake system, a steering wheel, four seats – and the average speed in London in 2001 was 17.5 miles per hour!That’s not a hell of a lot of return for the money. Ford evidently doesn’t have much to teach us about change. The fact that they’re still manufacturing cars is not proof that Ford Motor Co. is a sound organization, just proof that it takes very large companies to make cars in great quantities — making for an almost impregnable entry barrier.Fifty years after the development of the jet engine, planes are also little changed. They’ve grown bigger, wider and can carry more people. But those are incremental, largely cosmetic changes.Taken together, this lack of real change has come to man that in travel — whether driving or flying — time and technology have not combined to make things much better. The safety and design have of course accompanied the times and the new volume of cars and flights, but nothing of any significance has changed in the basic assumptions of the final product.At the same time, moving around in cars or aero-planes becomes less and less efficient all the time Not only has there been no great change, but also both forms of transport have deteriorated as more people clamour to use them. The same is true for telephones, which took over hundred years to become mobile or photographic film, which also required an entire century to change.The only explanation for this is anthropological. Once established in calcified organizations, humans do two things: sabotage changes that might render people dispensable, and ensure industry-wide emulation. In the 960s, German auto companies developed plans to scrap the entire combustion engine for an electrical design. (The same existed in the 1970s in Japan, and in the 1980s in France.) So for 40 years we might have been free of the wasteful and ludicrous dependence on fossil fuels. Why didn’t it go anywhere? Because auto executives understood pistons and carburettors, and would be loath to cannibalize their expertise, along with most of their factoriesAccording to the above passage, which of the following statements is true?
