For the past several years, the Sunday newspaper supplement Parade has featured a column called "Ask Marilyn". People are invited to query Marilyn vos Savant, who at age 10 had tested at a mental level of someone about 23 years old; that gave her an IQ of 228-the highest score ever recorded. IQ tests ask you to complete verbal and visual analogies, to envision paper after it has been folded and cut, and to deduce numerical sequences, among other similar tasks. So it is a bit confusing when vos Savant fields such queries from the average Joe (whose IQ is 100) as, What’s the difference between love and fondness or what is the nature of luck and coincidence It’s not obvious how the capacity to visualize objects and to figure out numerical patterns suits one to answer questions that have eluded some of the best poets and philosophers. Clearly, intelligence encompasses more than a score on a test. Just what does it means to be smart How much of intelligence can be specified, and how much can we learn about it from neurology, genetics, computer science and other fields The defining term of intelligence in humans still seems to be the IQ score, even though IQ tests are not given as often as they used to be. The test comes primarily in two forms: the Stanford-Binet Intelligence Scale and the Wechsler Intelligence Scales (both come in adult and children’s version). Generally costing several hundred dollars, they are usually given only by psychologists, although variations of them populate bookstores and the World Wide Web. Superhigh scores like vos Savant’s are no longer possible, because scoring is now based on a statistical population distribution among age pecks, rather tan simply dividing the mental are by the chronological age and multiplying by 100. Other standardized tests, such as the Scholastic Assessment Test (SAT) and the Graduate Record Exam (GRE), capture the main aspects of IQ tests. Such standardized tests may not assess all the important elements necessary to succeed in school and in life, argues Robert J. Sternberg. In his article "How Intelligent Is Intelligence Testing". Steinberg notes that traditional tests best assess analytical and verbal skills but fail to measure creativity and practical knowledge, components also critical to problem solving and life success. Moreover, IQ tests do not necessarily predict so well once populations or situations change. Research has found that IQ predicted leadership skills when the tests were given under low-stress conditions, but under high-stress conditions, IQ was negatively correlated with leadership--that is it predicted the opposite. Anyone who has toiled through SAT will testify that test-taking skill also matters, whether it’s knowing when to guess or what questions of skip.

It never rains but it pours. Just as bosses and boards have finally sorted out their worst accounting and compliance troubles, and improved their feeble corporation governance, a new problem threatens to earn them--especially in America--the sort of nasty headlines that inevitably lead to heads rolling in the executive suite: data insecurity. Left, until now, to odd, low-level IT staff to put right, and seen as a concern only of data-rich industries such as banking, telecoms and air travel, information protection is now high on the boss’s agenda in businesses of every variety. Several massive leakages of customer and employee data this year--from organizations as diverse as Time Warner, the American defense contractor Science Applications International Corp and even the University of California. Berkeley--have left managers hurriedly peering into their intricate 11 systems and business processes in search of potential vulnerabilities. "Data is becoming an asset which needs no be guarded as much as any other asset." says I am Mendelson of Stanford University’s business school. "The ability guard customer data is the key to market value, which the board is responsible for on behalf of shareholders". Indeed, just as there is the concept of Generally Accepted Accounting Principles (GAAP), perhaps it is time for GASP. Generally Accepted Security Practices, suggested Eli Noam of New York’s Columbia Business School. "Setting the proper investment level for security, redundancy, and recovery is a management issue, not a technical one." he says. The mystery is that this should come as a surprise to any boss. Surely it should be obvious to the dimmest executive that trust, that most valuable of economic assets, is easily destroyed and hugely expensive to restore--and that few things are more likely to destroy trust than a company letting sensitive personal data get into the wrong hands. The current state of affairs may have been encouraged--though not justified--by the lack of legal penalty (in America, but not Europe) for data leakage. Until California recently passed a law, American firms did not have to tell anyone, even the victim, when data went astray. That may change fast lots of proposed data-security legislation now doing the rounds in Washington. D. C. Meanwhile, the theft of information about some 40 million credit-card accounts in America, disclosed on June 17th, overshadowed a hugely important decision a day earlier by America’s Federal Trade Commission (FTC) that puts corporate America on notice that regulators will act if firms fail to provide adequate data security. The statement: "It never rains but it pours" is used to introduce ______ .

Which of the following may be required in an intelligence test
设随机变量X服从二项分布B(n，p)，则随机变量Y=n-X所服从的分布为______。
In this part you are going to read six passages. Each of the passages is followed by some questions or unfinished statements. For each question there are four choices marked A, B, C and D. Decide on the best choice according to the passage you read and write your choice. If you were to examine the birth certificates of every soccer player in 2006’s World Cup tournament you would most likely find a noteworthy quirk elite soccer are more likely to have been born in the earlier months of the year than in the later months. If you then examined the European national youth teams that feed the World Cup and professional ranks, you would find this strange phenomenon to be even more pronounced. What might account for this strange phenomenon Here are a few guesses: a) certain astrological signs confer superior soccer skills, b) winter-born bathes tend to have higher oxygen capacity which increases soccer stamina. c) soccer mad parents are more likely to conceive children in springtime at the annual peak of soccer mania, d) none of the above. Anders Ericsson, a 58-year-old psychology professor at Florida State University, says he believes strongly in "none of the above". Ericsson grew up in Sweden, and studied nuclear engineering until he realized he realized he would have more opportunity to conduct his own research if he switched to psychology. His first experiment nearly years ago, involved memory: training a person to hear and then repeat a random series of numbers. "With the first subject, after about 20 hours of training his digit span had risen from 7 to 20," Ericsson recalls. "He kept improving, and after about 200 hours of training he had risen to over 80 numbers." This success coupled with later research showing that memory itself as not genetically determined, led Ericsson to conclude that the act of memorizing is more of a cognitive exercise than an intuitive one. In other words, whatever inborn differences two people may exhibit in their abilities to memorize those differences are swamped by how well each person "encodes" the information. And the best way to learn how to encode information meaningfully, Ericsson determined, was a process known as deliberate practice. Deliberate practice entails more than simply repeating a task. Rather, it involves setting specific goals, obtaining immediate feedback and concentrating as much on technique as on outcome. Ericsson and his colleagues have thus taken to studying expert performers in a wide range of pursuits, including soccer. They gather all the data they can, not just predominance statistics and biographical details but also the results of their own lavatory experiments with high achievers. Their work makes a rather startling assertion: the trait we commonly call talent is highly overrated. or, put another way, expert performers whether in memory or surgery, ballet or computer programming are nearly always made, not born. The birthday phenomenon found among soccer players is mentioned to ______ .
