Since January 1974, new mobile homes have been required to have ground fault interrupter breakers for all exterior outlets. This sensitive circuit breaker deals with three kinds of circuit trouble. (1) The breaker opens—that is, it disconnects the circuit—if there’s an overload from too many appliances or from a short in an appliance or between circuit wires. (2) A break in the ground return wire of the circuit also trips this kind of breaker.
(3) Most important, the ground fault interrupter detects a ground that’s not part of the normal circuit. For an example, imagine you’re using one of your electrical tools outside and it develops a short between the hot wire and the handle of the tool. When you turn the tool on, your body forms an extra ground path for the electric current. You’d receive a terrible shock or be electrocuted—except for this new type of breaker. This device senses the abnormal grounding (through your body) and kicks off the power to the circuit. It trips when unnatural ground current reaches 5 milli amps. A strong heart can withstand 15 to 20 milli amps briefly without serious harm. The special breaker cuts power before you hardly feel a thing. You’re saved. Whenever this kind of breaker kicks out, replace the tool or appliance or have it repaired before you plug it in again.

In the past decade or so, the publishing industry has been confronted with powerful new competitors. For example, mountains of information and entertainment now stream into readers’ homes as a result of the emergence of the Internet and the explosive expansion of cable television. Access has become easy and virtually universal because it leapfrogs boundaries. In the process, it’s changed the culture.
Simultaneously, the book-publishing industry has gone through massive changes. It has consolidated dramatically. Imprints that were formerly rivals are now sister companies and partners. Standardized, corporate organizational practices have replaced looser, more hands—on, family-oriented operations. Book publishing has also benefited from waves of technical innovations that have impacted virtually every aspect of the business, including how books are printed, distributed, and sold.
Picture today’s book-publishing industry as a sharply pointed triangle. The narrow top of the triangle contains a handful of players, while the bottom portion is densely packed. As the triangle rises, the mass of publishing companies thins.

It is the tradition of this country to encourage individuals to become entrepreneur. Few government controls, for example, prevent a person from launching a new business. Almost anyone who wishes to do so may start a business. As a result, many new businesses spring up yearly in shopping malls and along highways and byways.
Small business is the term applied to any business that is operated by one or a few individuals. Because it is normally costly to start a manufacturing business, few small firms produce goods. Most small businesses are commonly found in service and retail trade fields that usually employ fewer than 100 people. Nearly 98 percent of all businesses in the country are classified as small. However, over half the total number of workers in this country are employed by businesses with fewer than 500 employees. In addition, the revenue generated from all small businesses accounts for about half of the GDP.
In recent years, when many large firms were laying off thousands of workers, small businesses with less than 20 employees were hiring in large numbers. Often, the new entrepreneurs were highly skilled managers who were displaced by large firms that were downsizing. Small firms, on the other hand, were reported to be hiring twice as many applicants as the number of employees laid off by large firms. In addition, many of these small firms were adding more high-paying jobs than low-paying jobs.
Many small businesses are one-person or family operations with only a few employees. Examples include restaurants, gift shops, real estate services, and bakeries. Many businesses also operate on a part-time or seasonal basis. Some examples include outdoor food stands and souvenir shops found at popular lake and ocean resorts. According to the U.S. Department of Commerce, many businesses earn less than $250,000 in yearly revenue, with many of the very small shops earning far less.
