Motivators are thing which an individual to perform. Whilw motivations reflect wants, motivators are the identified rewards, or incentives, that sharpen the drive to satisfy these wants. They are also the means by which conflicting needs may be reconciled or one need heightened so that it will be given priority over one another. Motivation refer to the drive and effort to satisfy a want or goal. A motivator then , is something that influences an individuals behaviour. It makes a difference in what a person will do. Obviously, in any organized enterprise, manager must be concerned about motivators and also inventive in their use. People can often satisfy their wants a variety of ways.A person can, for example, satisfy a desire for affiliation by being active ina social club rather that in business, meet economic need by performing a job just well enough to get by, or satisfy status needs by spending time working for a political party. What a manager must do, of course, is use those motivators which will lead people to perform effectively for the enterprise that employs them no manager can expect to hire the whole person, since people always have desires and drives outside the enterprise. But if a company or any other kind of eneterprise is to be efficient and successful, enough of every person’s drives must be stimulated and satisfied to ensure effective performance.

Clean drinking water and basic sanitation are necessary to prevent communicable diseases and to maintain a healthy life.For many of the world’s poorest people, one of the greatest environmental threats to health remains the continued use of polluted water. In 2002 the United Nations estimated that at least 1.1 billion people lacked access to safe drinking water and 2.4 billion do not have adequate sanitation. These deficiencies result in hundreds of millions of cases of water related illness and more than5 million deaths every year. As population grow, more people move into cities and agriculture and industry compete for increasingly source water supplies, water shortage are expected to become even worse. By 2025, two thirds of the world’s people will be living in more than 10% of renewable freshwater resources. One of the highest priorities announced at the U.N. World summit in Johannesberg in 2002, is to reduce by one-half the proportion of people without reliable access of clean-water and improved sanitation.

Life in the modern world is coming to depend more and more upon ‘technical’ means of communication, mobile and telephone, radio, computer, printing.Without such technical aids, the modern needed, that railways can run on a schedule; that law and order are maintained; that education is possible. Communication renders true social life practicable, for communication means organization. Communications have enabled the social unit to grow from the village to the town, to the modern city state , untill today we see organized systems of mutual dependance grown to cover whole hemispheres.

The need for closer interaction between technical institutions and industry has been emphasized time and again. It is of great importance that technical institutions and industry should act as parteners in the development of a technologist and each must play the role that it is best fitted for. The need for such close interaction and collaboration has become all the more urgent in view of the challenge posed by the latest situations in the field of technical education which require greater attention to a number of important factors. These improvement of the quality of technical education, diversification of courses, development of the faculty of technical institutions by way of training of teachers, development of the curriculum to make the courses move live and dynamic and organisation of sandwich courses to effect a break through in new directions.

The internet revolution and e-commerce particularly have ushered in an era of mass customisation. Thus, never before has customer service been so important as in this era. Several factors have led to this mass customisation, the biggest change brought about by the Net.

The customers not only have the information on products and prices but also on the latest trends, competition, changing laws and government policies. This naturally makes them more aware and alert, reducing chances of their being duped or cheated by businessmen.

However, as the use of Net evolves in the country, the buying habits too, are bound to chnage. E-commerce markets will hold out possibilities which may seen unthinkable at present. Also let’s not forget that e-commerce is not about Net shopping alone. It includes a wide range of activities like stock and bond transactions, renting of properties and auctions etc.

Inerties is also being used in India for online trading. Online trading gives complete control of the transaction to the individual in terms of the prices, depth of the market, execution rates and so on. It also provides the liberty of carrying out transaction any time and anywhere.

With every passing day more and more utilities of internet are coming to the force and Indians are making valuable contributions in the field of information technology of which internet is a valuable part. Let us hope , with the availability of a vast amount of knowledge and rapid interaction via, the net. Indian and the world citizens amerge more knowledgeable persons and the world becomes a better place to live in.

Make a precis of the following passage and give a suitable title to it.

As we are in the twenty-first century, we are witnessing the emergence of a new kind of social scientist – the non verbalist. Just as the bird watcher delights in watching birds and their behavior, so the non-verbalist delights in watching the non-verbal cues and signals of human beings. He watches them at social functions, at beaches, on television, at the office or anywhere that people interact. He is a student of behaviour who wants to learn about the actions of his fellow humans so that he may ultimately learn more about himself and how he can improve his relationship with others.

It seems almost incredible that, over the million or more years of man’s evolution, the non-verbal aspects of communication have been actively studied on any scale only since the 1960s and that the public has become aware of their existence only since Julius Fast published a book about body language in 1970. This was a summary of the workdone by behavioural scientists on non-verbal communication up until that time and even today, most people are still ignorant of the existence of body language, let alone its importance in their lives.

Charlie Chaplin and many other silent movie actors were pioneers of non-verbal communication skills; they were the only means of communication skills; they were the only means of communication available on the screen. Each actor was classed as good or bad by the extent to which he could use gestures and other bdy signals to communicate effectively. When talking films became popular and less emphasis was placed on the non-verbal aspects of acting, many silent movie actors faded into obscurity and those with good verbal skills prevailed.
