【单选题】By the mid-1990s, banks and investment organizations had realized that academics skilled in mathematical modelling could help them to devise winning strategies with which to play the world’’s financial markets. George Sugihara, who had built a formidable reputation among ecologists by analyzing the population dynamics of fish and plankton (浮游生物), was a prize catch.DeutscheBank wanted him to apply those talents to its "black-box project", a secret endeavour designed to predict the prices of various financial instruments.Sugihara struck a hard bargain. In addition to providing an ample salary,DeutscheBank agreed to let him stay in SanDiego — where the Frankfurt-based firm provided a large luxurious office overlooking the harbour. There, it gave him all the resources he needed to devise models to interpret price trends from masses of financial dat
A、In 1995, when Sugihara took leave of absence from the University ofCalifornia, SanDiego (UCSD、, his colleagues thought it unlikely that he would ever return — few scientists who have been seduced by the world of finance have later resumed their academic careers.But Sugihara has changed that trend, and is now applying his experience in finance to marine conservation. He wants to harness market forces to prevent over-fishing — which governments and the scientists who advise them have mostly so far failed to achieve.In reality, Sugihara never gave up his studies of biological oceanography.During his four years withDeutscheBank, he taught part-time at UCSD, and published more than a dozen scientific articles on complex biological systems. When his leave period was up, he says, hard science was always going to win over high finance. "No, it wasn’’t hard to leave that world," he says. "I really wanted to do science." But Sugihara’’s experience of the markets has changed the way he thinks about managing the ocean’’s natural resources. For decades, investors have traded on markets for the future prices of virtually every commodity, from grain crops, through orange juice, to oil. Yet despite worldwide sales of at least US$80 billion a year, there is no futures market for fish. Sugihara hopes to change that.By providing people with the means to make money, and offering a structured financial environment for the worldwide catch and sale of fish, he argues, it should be possible to prevent stock depletion.Trading placesTo this end, Sugihara and a number of scientific colleagues are now seeking start-up finance for a company called the Ocean ResourceExchange. This would trade and lease financial instruments or derivatives associated with fish catches, on an electronic commodities exchange.Perhaps trading is in Sugihara’’s genes. His Japanese father was a trader in wood products, who settled inCalifornia in 1951 with his Indonesian wife and young son, seeking new opportunities away from the turmoil of post-warAsi
A、But the young Sugihara didn’’t follow his father into business.After graduating from the University of Michigan in 1973, he embarked on an academic career, initially studying lake cores inAfric
A、First he worked in Zambia, where he identified pollens and diatoms for palaeoclimate (古气候) studies. Later, he moved to Tunisia to study algal productivity and the origins of hydrogen sulphide emissions from Lake Tunis.Sugihara’’s analytical mind found this fieldwork unsatisfying, so he returned to Michigan to bone up (突击钻研) on mathematics. "I took 26 courses in two years," he says.And with his growing mathematical sophistication, he developed a theory to explain an observed regularity in the distribution of species abundance. When he approached Robert May, then conducting pioneering analyses of biodiversity at the Institute forAdvanced Study in Princeton, New Jersey, with the theory, May immediately recognized Sugihara’’s potential — and signed him up as a doctoral student.By the time Sugihara completed his PhD、in 1982, he already had his
