These are legitimate needs for the task. But the work an be done more quickly and efficiently with a word processor.

It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves.

The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought on impulse: someone has a sudden desire for an ice cream sundae on a hot day. Or they may be purchased as emergency items.

Shopping goods fall into two classes:those that are perceived as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such
things as home appliances, television sets, and automobiles. Having decided on the model desired, the cus tomer is primarily interested in getting the item at the most favorable price. Items regarded as inherently different include clothing, furniture, and dishes. Quality, style, and fashion will either take precedence over price, or they will not matter at all. Specialty goods have characteristics that impel cus tomers to make special efforts to find them. Price may be no consideration at all. Specialty goods can include almost any kind of product. Normally, specialty goods have a brand name or other distinguishing characteristics. Unsought goods are items a consumer does not necessarily want or need or may not even know about Promotion or advertising brings such goods to the consumer s attention. The product could be some thing new on the market as the Sony Walkman once was or it may be a fairly standard service, such as life insurance, for which most people will usually not bother shopping.

In chess a player tries to trap his opponents king in a series of moves On creating a lens, lens designers attempts to "trap" light by forcing all the rays arising from a single point in the subject to converge on a single point in the image,as a consequence of their passing through a series of transparent elements with precisely curved surfaces. Since in both cases the ultimate goal and the means by which it can be attained are known, one is tempted to think there will be a single best decision at any point along the way. The number of possible consequences flowing from any one decision is so large, however, as to be virtually, if not actually, infinite. Therefore in lens design, as in chess, perfect solutions to a problem are beyond reach. The same principles apply to all lenses. The lens designer has one enormous advantage over the chess player. The designer is free to call on any available source of help to guide him through the countless number of possibilities. Most of that help once came from mathematics and physics, but recently computer technology, information theory, chemistry, industral engineering and psychophysics have all contributed to making the designers job immeasurably more productive. Some of the lenses on the market today were conceivable a decade ago. Others whose design is as much as a century old can now be mass by the millions, both out of glass and out of plastics. Todays lenses are better thay are made produced at low cost. With the development of automatic production methods, lenses best lenses used by the great photographers of the past. Moreover, their price may be lower, in spite of fact that the 19th century craftsmen worked for only a few dollars a week and today s lenses are more complex. The lens desigher cannot fail to be grateful for the science and technology that have made his work easier and his creations more widely available, but he is also humbled: it is no longer practical for a fine photographic lens to be designed from beginning to end by a single human mind In what way does lens design resemble chess? A In the number of steps each takes towards the goal

But currently, there is no federal standard for pesticide free " organically grown" foodsfoods grown without synthetic pesticides or fertilizers. The result, says U. S. Senate Agriculture Committee Chairman Patrick Leahy, is that consumers " too often see confusing and unsubstantiated claims such as‘ organically grown’and‘ natural’ Currently, 22 states have some kind of certification program or at least requirements for third party certification. Look for the words"certified organically grown"or similar wording.

In most cases, that means that no synthetic pesticides have been used in three years and that no synthetic fertilizers have been used in two or three years. Even if your state does not have its own program, you may have seen organically grown produce in the marketplace. If you want to know exactly what that means, ask the store's manager or the produce buyer about how the store's “organic” produce was grown.

At times, he was affectionate, played with the child, and told him interesting and imaginative stories. At other times he showed violent outbursts of rage and would beat his son so badly that the child thought he would be killed. The boy had numerous fantasies. including one in which his father was killed by a cunning bandit who came to the house cleverly disguised as the father. As Angyal put it, the fantasy dramatized the childs confusion as to whether he was living in a loving house or in a cruel, alien world that merely masqueraded as pleasant. The fantasy was aimed at dispelling his confusion about the father, whose behaviour made him both God and devil But this daydream, implying the murder and loss of the underlying good father, was unacceptable to the boy and failed to solve his doubts.
