案例分析题Set 5President Hoover’s Politics During the Great DepressionAt first everything seemed fine and dandy. America was enjoying one of the biggest economic surges in the nation’s history. However, even though America benefited from the economic boom of the so called "Roaring Twenties", the imbalance between the rich and the poor combined with the production of more and more goods and rising personal debt caused one of the biggest recessions in history. On Black Tuesday, October 29, 1929, the stock market crashed, triggering the Great Depression, which was the worst economic collapse in the history of the modem, industrial world. It spread from the United States and rippled out to the rest of the world, with banks failing and businesses going bust for over a span of a decade, leaving more than a quarter of the working force in America without jobs.President Herbert Hoover, underestimating the seriousness of the crisis, called it "a passing incident in our national lives," and assured Americans that it would be over within two months. Hoover did not think that the federal government should offer relief to the poverty-stricken population because he firmly believed in individualism. Focusing on economic programs to help finance businesses and banks, Hoover met with resistance from business executives who preferred to lay off workers. Blamed by many for the Great Depression, Hoover was widely ridiculed.Hoover’s economy was put to the test with the onset of the Great Depression in 1929. It was his vocal stance on non-intervention that led to Democratic criticism that Hoover was a "sitting duck" president; on the other hand, his more pro-free market opponents also denied he was a laissez-faire president and condemned him for being an interventionist. Hoover tried to restore confidence with a series of speeches but his weak speaking style hampered these efforts. The biggest problem was that his predictions of an upturn just around the comer never materialized. His promises were not delivered and he lost a lot of the public’s confidence.Together, the government and businesses actually spent more in the first half of 1930 than the previous year; yet frightened consumers cut back their expenditures by ten percent. A severe drought ravaged the agricultural heartland beginning in the summer of 1930, while foreign banks declared bankruptcy, draining U.S. wealth and destroying world trade. The combination of these factors caused a downward spiral: as earning fell, domestic banks collapsed, and mortgages were called in. Hoover’s hold-the- line policy in wages lasted little more than a year. Unemployment soared from five million in 1930 to over eleven million in 1931, causing this sharp recession to become the Great Depression.In 1930, Hoover reluctantly signed the Smoot-Hawley Tariff Act, which raised tariffs on over 20,000 dutiable items. The Tariff, combined with the 1932 Revenue Act, which hiked taxes and fees across the board, is often blamed for deepening the economic depression, and is considered by some to be Hoover’s biggest political mistakes. Moreover, the Federal Reserve System’s tightening of the money supply is also regarded by most modem economists as a mistaken tactic, under the circumstances.In order to cover the expenses of these government programs, Hoover agreed to one of the largest tax increases in American history.The Revenue Act of 1932 raised taxes on the highest incomes from 25% to 63%, while the estate tax was doubled, and corporate taxes were raised by almost 15%.Also, a "check tax" was included that placed a 2-cent tax on all bank checks. During the 1932 elections, Hoover’s opponents blasted the Republican incumbent for spending and taxing too much, increasing national debt, raising tariffs, and blocking trade, as well as placing millions on the dole of the government.Roosevelt attacked Hoover for "reckless and extravagant" spending, and of leading "the greatest spending administration in peacetime in all of history."Unemployment rose to 24.9% by the end of Hoover’s presidency in 1933, a year that is considered to be the depth of the Great Depression. The author mentions the unemployment rates of 1930 and 1931 in order to().

案例分析题Set 2Gadgets with a Sporting ChanceConsumer electronics: New sports equipment, from tennis rackets to running shoes, uses processing power to enhance performance. Is that fair Why should aspiring athletes stand on the sidelines when a spot of electronic assistance can put them in the middle of the game That is the question many sports-equipment makers are asking as they sense an opportunity to boost their sales with high-tech products. You could call it the revenge of the nerds: a new wave of microchip-equipped sporting goods promises to enhance the performance of novices and non-sporting types alike--and could even make difficult sports easier.Take cross-country skiing. Victor Petrenko, an engineer at Dartmouth College’s Ice Research Lab in New Hampshire, has invented some smart ski-brakes that, he believes, will increase the popularity of cross-country skiing by making the sport less challenging for beginners. The brakes, currently being tested by a ski manufacturer in the Alps, offer the necessary friction for a bigger "kick-off force" and make the skis less likely to slide backwards in their trucks. To make this happen, an electric current from the bottom of the skis pulses through the ice, melting a thin layer of snow that instantly refreezes and acts as a sort of glue.This is not the only form of smart ski to hit the slopes. Atomic, a leading ski-maker based in Austria, plans to introduce a system later this year that runs a diagnostic safety check to ensure that the ski binding is properly closed, with the result being shown on a tiny built-in liquid-crystal display. Meanwhile, tennis equipment manufacturers are hoping that innovation will bring new zip to their business as well. They certainly need to do something: according to Sport ScanInfo, a market-research firm based in Florida, sales of tennis rackets in America fell 12.5% during the first half of 2004 compared with the first half of 2003.With the ball clearly in their court, researchers at Head, a maker of sporting equipment, have devised a product that should appeal to players suffering from tennis elbow. A chip inside the racket controls piezo-electric fibres, which convert mechanical energy from the ball’s impact into electrical potential energy. This energy is then used to generate a counter-force in the piezo-electric fibres that causes a dampening effect. All of this, the firm says, translates into less stress on the elbow. Head claims that residual vibrations in the racket are dampened twice as fast as in conventional rackets, reducing the shock experienced by the player’s arm by more than 50%.No doubt purists will object that this is simply not cricket. Rule-makers in many sports are now being forced to consider the implications of equipment that promises to augment athletes’ performance with electronic muscle. The International Tennis Federation, that body is responsible for setting the rules of the game, has specified in its most recent guidelines that "no energy source that in any way changes or affects the playing characteristics of a racket may be built into or attached to a racket".Yet despite such wording, the guideline does not actually eliminate the use of Head’s smart rackets, because there is no external energy source---the damping effect relies solely on energy from the ball’s impact. Though high-tech equipment may cause controversy on the court, tennis clubs have to adhere to the guidelines set for the sport, explains Stuart Miller, the ITF’s technical manager. And if the rules allow self-generated forces to modify a racket’s response, so be it.Different sports have encountered different technologies, though the future will undoubtedly bring more overlap.In golf, gadgets that pinpoint the location of the green using the Global Positioning System (GPS),The rule-making body of the Royal and Ancient Golf Club of St. Andrews, which oversees the game in all countries except America and its dependencies, currently prohibits the use of distance-measuring devices.As a result, golfers cannot rely on GPS aids in a tournament. While technological innovation in golf equipment should continue, the player’s skill should remain the predominant factor, says David Rickman, who is in charge of the club’s rules and equipment standards.The trend towards high-tech assistance is not limited to sports with a reputation for expensive gear, however. Even runing, that most basic of sports, provides scope for electronic enhancement. The Adidas running shoe, which is due to be launched in December, incorporates a batterypowered sensor that takes about 1,000 readings a second. A microprocessor then directs a tiny embedded electric motor to adjust the characteristics of the sneaker, enableing it to change the degree of cushioning depending on the surface conditions and the wearer’s running style and foot position. The race for the smartest use of microchips in sporting equipment, it seems, has begun. What is the purpose of the most recent guidelines made by the ITF().

The exoskeletons and head-mounted displays featured in the film "Aliens", for example, spawned a number of militaryfunded projects to try to create similar technologies. Automatic sliding doors might never have become popular had they not appeared on the television series "Star Trek". And the popularity of flip-top or "clamshell" mobile phones may stem from the desire to look like Captain Kirk flipping open his communicator on the same program.Now it seems that "Star Trek" has done it again. This month, American soldiers in Iraq will begin trials of a device inspired by the "comm badge" featured in "Star Trek: The Next Generation". Like crew members of the starship Enterprise, soldiers will be able to talk to other members of their unit just by tapping and then speaking into a small badge worn on the chest. What sets the comm badge apart from a mere walkie-talkie, and appeals to "Star Trek" fans, is the system’s apparent intelligence. It works out who you are calling from spoken commands, and connects you instantly.The system, developed by Vocera Communications of Cupertino, California, uses a combination of Wi-Fi wireless networking and Voice-overInternet Protocol (VoIP) technologies to link up the badges via a central server, akin to a switchboard. The badges are already being used in 80 large institutions, most of them hospitals, to replace overhead paging systems, says Brent Lang, Vocera’s vice-president.Like its science-fiction counterpart, the badge is designed so that all functions can be carded out by pressing a single button. On pressing it, the caller gives a command and specifies the name of a person or group of people, such as "call Dr. Smith" or "locate the nearest anesthesiologist". Voice-recognition software interprets the commands and locates the appropriate person or group, based on whichever Wi-Fi base-station they are closest to. The person receiving the call then hears an audible alert stating the name of the caller and, if he or she wishes to take the call, responds by tapping the badge and starting to speak.That highlights a key difference between the "Star Trek" comm badge and the real-life version:Vocera’s implementation allows people to reject incoming calls, rather than having the voice of the caller patched through automatically.But even the most purist fans can forgive Vocera for deviating from the script in this way, says David Batchelor, an astrophysicist and "Star Trek" enthusiast at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.For there are, he notes, some curious aspects to the behavior of the comm badges in "Star Trek".When the captain of the Enterprise says "Picard to sick-bay: Medical emergency on the bridge", for example, his badge somehow connects him to the sick-bay before he has stated the destination of the call.Allowing badge users to reject incoming calls if they are busy, rather than being connected instantly, was a feature added at the request of customers, says Mr. Lang. But in almost all other respects the badges work just like their fictional counterparts. This is not very surprising, says Lawrence Krauss, an astrophysicist at Case Western Reserve University in Cleveland, Ohio, and the author of "The Physics of Star Trek". In science fiction, and particularly in "Star Trek", most problems have technological fixes. Sometimes, it seems, those fixes can be applied to real-world problems too.Vocera’s system is particularly well suited to hospitals, says Christine Tarver, a clinical manager at E1 Camino Hospital in Mountain View, California. It allows clinical staff to reach each other far more quickly than with beepers and overhead pagers. A recent study carried out at St. Agnes Healthcare in Baltimore, Maryland, assessed the amount of time spent by clinical staff trying to get hold of each other, both before and after the installation of the Vocera system. It concluded that the badges would save the staff a total of 3,400 hours each year.Nursing staff often end up playing phone tag with doctors, which wastes valuable time, says Ms Tamer. And although people using the badges sometimes look as though they are talking to themselves, she says, many doctors prefer it because it enables them to deal with queries more efficiently. The system can also forward calls to mobile phones; it can be individually trained to ensure that it understands users with strong accents; and it can even be configured with personalized ring tones.In Iraq, soldiers will use the Vocera badges in conjunction with base-stations mounted on Humvee armored vehicles. Beyond medical and military uses, Vocera hopes to sell the technology to retailers and hotels. And the firm’s engineers are now extending the system to enable the badges to retrieve stored information, such as patient records or information about a particular drag, in response to spoken commands. Their inspiration Yet another "Star Trek" technology: the ship’s talking, ship’s computer. Which of the following is true about the vocera badge is different from the fictional version.()
