High Percentage of Accidents Placing a human being behind the wheel of an automobile often has the same curios effect as cutting certain fibres in the brain. The result in either case is more primitive behaviour. Hostile feelings are apt to be expressed in an aggressive way. The same man who will step aside for a stranger at a doorway will, when behind the wheel, risk an accident trying to beat another motorist through an intersection. The importance of emotional factors in automobile accidents is gaining recognition. Doctors and other scientists have concluded that the highway death toll resembles a disease epidemic and should be investigated as such. Dr Ross A. McFarland, Associate Professor of industrial Hygiene at the Harvard University School of Public Health, aid that accidents "now constitute a greater threat to the safety of large segments of the population than diseases do. " Accidents are the leading cause of death between the ages of 1 and 35. About one third of all accidental deaths and one seventh of all accidental injuries are caused by motor vehicles. Based on the present rate of vehicle registration, unless the accident rate is cut in half, one of every 10 persons in the country will be killed or injured in a traffic accident in the next 15 years. Research to find the underlying causes of accidents and to develop ways to detect drivers who are apt to cause them is being conducted at universities and medical centres. Here are some of their findings so far: A man drives as he lives. If he is often in trouble with collection agencies, the courts, and police, he will have repeated automobile accidents. Accident repeaters usually are egocentric, exhibitionistic, resentful of authority, impulsive, and lacking in social responsibility. As group, they can be classified as borderline psychopathic personalities, according to Dr. McFarland. The suspicion, however, that accident repeaters could be detected in advance by screening out persons with more hostile impulses is false. A study at the University of Colorado showed that there were just as many overly hostile persons among those who had no accidents as among those with repeated accidents. Psychologists currently are studying Denver high school pupils to test the validity of this concept. They are making psychological evaluations of the pupils to see whether subsequent driving records will bear out their thesis. The author believes that, behind the wheel of an automobile, some people act ______.

What Is Market The word market is used in a number of ways. There is a stock market and an automobile market, a retail market for furniture and a wholesale market for furniture. One person may be going to the market: another may plan to market a product. What, then is a market A market may be defined as a place where buyers and sellers meet, goods or services are offered for sale. and transfers of ownership occur. A market may also be defined as the demand made by a certain group of potential buyers for a good or service. For instance, there is a farm market for petroleum products. The terms market and demand are often used interchangeably; they may also be used jointly as market demand. These definitions are not sufficiently precise to be useful to us here. For business purposes we define a market as people or organizations with wants (needs) to satisfy, money to spend, and the willingness to spend it. Thus in the market demand for any given product or service, there are three factors to consider—people or organizations with wants(needs),their purchasing power, and their buying behavior. We shall employ the dictionary definition of needs: the lack of anything that is required, desired, or useful. We do not limit needs to the narrow physiological requirements of food, clothing and shelter essential for survival. In our discussion the words needs and wants are used synonymously and interchangeably. In a strict interpretation, however, needs would refer to such basic physiological requirements as food, clothing, and shelter, while wants would be non-basic preferences. However, in our affluent society, little is to be gained by trying to differentiate between the two. Many of us would see as needs some items that are far beyond food, clothing, and shelter. Markets can be classified according to what is sold on a market and how goods are sold.
