______,there was a revival in literacy.
Wealthy people tend to think differently on social issues from poor people. Factory workers probably do not share the same views as white-collar, nonunion workers. Women employed outside their homes sometimes have perspectives different from those of fulltime home makers. In these and other ways individual status shapes one's view of current events.
The mass media, especially television, are powerful influences on the way people think and act. Government officials note how mail from the public tends to "follow the headlines". Whatever is featured in newspapers and magazines and on television attracts enough attention that people begin to inform. them and to express opinions.
The mass media have also created larger audiences for government and a wider range of pubic issues than existed before. Prior to television and the national editions of newspapers, issues and candidates tended to remain localized. In Great Britain and West Germany, for ex ample, voters as local contests usually viewed elections to the national legislatures. Today's elections are seen as struggles between party leaders and programs. In the United States radio and television have been beneficial to the presidency. Since the days of Franklin D. Roosevelt and his "fireside chats", presidents have appealed directly to a national audience over the heads of Congress to advocate their pro grams.
Special groups spend vast sums annually trying to influence public opinion. Public utilities, for instance, tried to sway public opinion in favor of nuclear power plants. Opposed to them were citizens' organizations that lobbied to halt the use of nuclear power. During the 1960s the American Medical Association conducted an unsuccessful advertising campaign designed to present the passage of medicate.
Opinion leaders are usually such prominent public figures as politicians, show business personalities, and celebrity athletes.
The opinions of these individuals, whether informed and intelligent or not carry weight with some segments of the population. Some individuals, such as Nobel prizewinners, are suddenly thrust into public view by the media. By quickly reaching a large audience, their views gain a hearing and are perhaps influential in shaping views on complex issues.
The second paragraph is mainly about ______.
The markup may be quite high 90 percent of cost or it may be low. Grocery items in a supermarket usually have a low markup, while mink cost have a very high one. High markups, however, do not in themselves guarantee big profits. Profits come from turnover. If an item has a 50 percent markup and does not sell, there is no profit. But if a cereal has an 8 percent markup and sells very well, there are reasonable profits.
While most pricing is based on cost factors, there are some exceptions. Prestige pricing means setting prices artificially high in order to attract select clientele. Such pricing attempts to suggest that the quality or style. of the product is exceptional or that the item cannot be found elsewhere. Stores can use prestige pricing to attract wealthy shoppers.
Leader pricing and bait pricing are the opposites of prestige pricing. Leader pricing means setting low prices on certain items to get people to come into the stores. The products so priced are called loss leaders because little or no profit can be made on them. The profits are made from other products people buy while in the store. Bait pricing, now generally considered illegal, means setting artificially low prices to attract customers. The store, however, has no intention of selling goods at the bait prices. The point is to get people into the store and persuade them of the inferiority of the low-priced item. Then a higher priced item is presented as a better alternative.
A common retail tactic is odd priced products. For some products of $300, the store will set the price at $295 or $299.95 to give the appearance of a lower price. Automobiles and other high-priced products are usually priced in this manner. For some reason $7995 has more appear to a potential car customer than $8000.
Bid pricing is a special kind of price setting. It is often used in the awarding of government contracts. Several companies are asked to submit bids on a job, and normally the lowest bidder wins. A school system may want to buy a large number of computers. Several companies are asked to submit prices, and the school district will decide on the best bid based as well on considerations of quality and service.
