The amount of sunlight reaching Earth’s surface appears to be growing. The phenomenon, which some dub "global brightening," (1) scientists with a puzzle. If the (2) is real and global, how long will it last and what are the consequences for climate change, the planet’s water cycle, and other (3) that draw energy from sunlight (4) , the answer might seem obvious: More sunlight reaching the ground in a warming world means that temperatures will get warmer (5) Not so fast, some researchers say. Additional warming would be certain (6) nothing else in the climate system changes. And the climate system is (7) static. Some combinations of changes could reinforce the heating; others could (8) it. Unraveling these interactions and forecasting their course require an accurate accounting of the sunlight reaching the surface and the (9) the surface sends skyward. Moreover, researchers say, measurements of the sun’s strength at Earth’s surface are potentially powerful tools for (10) human influences on the climate.
Earth’s radiation "budget" (11) an "extremely important parameter that is (12) known," says Robert Charlson, an atmospheric scientist at the University of Washington at Seattle. "It needs to be (13) much better than it is." (14) about the amount of sunlight reaching Earth’s surface were first raised in 1974. Researchers from the United States and Israel recorded a 12% drop (15) sunlight over 40 years at a (16) station in the southern Sinai Peninsula. Since then, others have used a variety of techniques to try to track (17) sunlight. Three years ago, for example, a (18) led by Beate Liepert at Columbia University’s Lamont-Doherty Earth Observatory gathered data from ground (19) around the world and found that solar radiation reaching the surface fell (20) 4% from 1961 to 1990.

Yamato, the ancient name of Japan, essentially means "big harmony". To achieve such balance, Japanese society has refined a plethora of cultural traits: humility, loyalty, respect and consensus. In the field of business, however, this often results in a lack of leaders who are willing to stand out from the crowd, promote themselves and act decisively. "The nail that sticks up gets hammered down" is a common Japanese refrain; "the hawk with talent hides his talons" is another. Whereas American and European bosses like to appear on the covers of global business magazines, their Japanese counterparts are comfortable in their obscurity. Business in Japan is generally run as a group endeavor.
Such democratic virtues served the country well in the post-war period. But today they hold too many Japanese firms back. Japan boasts some of the best companies in the world: Toyota, Canon and Nintendo are the envy of their industries. But they operate on a global scale and have tentatively embraced some unconsensual American methods. In much of the Japanese economy-especially its huge domestic services sector-managers are in something of a funk. Firms do not give promising youngsters responsibility early on, but allocate jobs by age. Unnecessarily long working hours are the norm, sapping productivity. And there are few women and foreigners in senior roles, which narrows the talent pool.
So how pleasing it is to be able to report the success of a business leader who breaks the mould. Young, dynamic and clever, he is not afraid to push aside old, conservative know- nothings. He disdains corporate politics and promotes people based on merit rather than seniority. He can make mistakes (he got involved in a questionable takeover-defence scheme), but he is wildly popular with salarymen: his every move is chronicled weekly. In June he was given the top job at one of Japan’s biggest firms. Kosaku Shima of Hatsushiba Goyo Holdings has only one serious shortcoming: he is not a real person, but a manga, or cartoon, character. For many critics of Japan, that says it all: Mr. Shima could exist only in fiction. In fact there is room for the country’s managers and even its politicians to learn from him.
Most of the lessons are for Japan’s managers. At present, bosses rarely say what they think because it might disrupt the harmony, or be seen as immodest. Their subordinates are reluctant to challenge ideas because that would cause the boss to lose face. So daft strategies fester rather than getting culled quickly. There is little risk-taking or initiative. The crux of the problem is Japanese companies’ culture of consensus-based decision-making. Called nemawashi ( literally, "going around the roots" ) or ringi ( bottom-up decisions), it helped to establish an egalitarian workplace. In the 1980s Western management consultants cooed that it was the source of Japan’s competitive strength. Sometimes it can be, as in periods of crisis when an entire firm needs to accept new marching orders quickly. But most of the time it strangles a company.
Relying on consensus means that decisions are made slowly, if at all. With so many people to please, the result is often a mediocre morass of compromises. And with so many hands involved, there is no accountability; no reason for individuals to excel; no sanction against bad decisions so that there are fewer of them in future. Of course, sometimes the consensus of the Japanese workplace is just a veneer and decisions are still made from on high. But then why persist with the pretence, particularly if it drains a company’s efficiency
Why do the critics say Mr. Kosaku Shima could only exist in fiction

A:He is a cartoon figure. B:His way of managing a company breaks all the existing norms of Japanese business circle. C:Many managers are afraid that his existence will disrupt the existing harmony. D:People cannot learn from his way of operating a company.

Virus Linked to Prostate (前列腺) Tumours

The researchers from the University of Utah and Columbia University medical schools found the virus in 27% of the 200 cancerous prostates they looked at. They say it was associated with more aggressive tumours and found in only 6% of non - cancerous prostates. The finding raises the prospect of one day producing a vaccine to protect against prostate cancer. This is the first report to link XMRV (Xenotropic murine leukaemia virus--related virus) to human cancers.
XMRV is a retrovirus like HIV which works by inserting a copy of its own DNA into the chromosomes (染色体) of a cell they infect. When this occurs to a gene that regulates cell growth, it can disrupt the normal development of the cell.
Dr Helen Rippon, Head of Research Management at The Prostate Cancer Charity, said the research was intriguing (吸引人的) but posed several key questions about the role the infection plays in prostate cancer. He said: " Around the world, extensive work is being undertaken to identify risk factors for prostate cancer which will enable treatments and tests for the disease to be refined. "
"It is critically important to identify key triggers of prostate cancer to improve early detection of the disease in men with potentially life threatening prostate cancer. "
XMRV is known to cause leukemia (白血病) and other tumours in animals. Dr Ila Singh, who led the study from the pathology department at the University of Utah, said: "We still don’t know that this virus causes cancer in people, but that is an important question we are going to investigate. "
Dr Chris Parker, Cancer Research UK’ s prostate cancer expert at the Institute of Cancer Research said: "This exciting study raises the possibility that the virus might contribute to the development of some prostate cancers. "
"In the future, if it turns out to he true, then we, could speculate about the possibility of vaccination to protect against prostate cancer, similar to the approach now used to prevent cervical cancer (子宫颈癌). /
How does the XMRV work to damage the human health

A:To stop the development of cells. B:To make the development of cells quicker than norm. C:To disrupt the development of cells. D:To destroy the development of genes.
