For more than a decade, the prevailing view of innovation has been that little guys had the edge. Innovation bubbled up from the bottom, from upstarts and insurgents. Big companies didn’t innovate, and government got in the way. In the dominant innovation narrative, venture-backed start-up companies were cast as the nimble winners and large corporations as the sluggish losers.
There was a rich vein of business-school research supporting the notion that innovation comes most naturally from small-scale outsiders. That was the headline point that a generation of business people, venture investors and policy makers took away from Clayton M. Christensen’s 1997 classic, The Innovator’s Dilemma, which examined the process of disruptive change.
But a shift in thinking is under way, driven by altered circumstances. In the United States and abroad, the biggest economic and social challenges—and potential business opportunities—are problems in m
A. business people are more innovative than government officials
B. all kinds of changes are disruptive activities in some sense
C. the dilemma of any innovation is its disruptive nature
D. small businesses are more creative than large companies -

Sadness isn’t manly—this Eric Weaver knew. When depression engulfed this New York police sergeant, it took a different guise: a near-constant state of anger. "One minute I’d be okay and the next minute I’d be screaming at my kids and punching the wall," he recalls. "My kids would ask, ’What’s wrong with Daddy Why’s he so mad all the time’" For years, Weaver didn’t know what was wrong.
Weaver’s confusion about what tortured him was not unusual. Roughly a third of the 18 million or more Americans who suffer depression each year are men. Yet all too often, experts say, men fail to recognize the symptoms and get the treatment they need.
For years, experts suspected that gender makes a big difference in depression. Studies from New York to New Zealand have repeatedly found the same startling statistic: About twice as many women as men suffer from depression. That finding was considered one
A. Mr. Weaver considered anger was a guise of depression
B. Depression may result in similar symptoms
C. Men generally ignore the signs of depression and its treatment
D. One third of male Americans suffer depression each year -

Rarely has there been as neat a fit between a book’s subject and its author’s biography as in "Bound Together: How Traders, Preachers, Adventurers, and Warriors Shaped Globalization" by Nayan Chanda. It’s easy to see why the subject fascinates Chanda; he’s a self-proclaimed Francophile(崇拜法国的人) of South Asian origin, who studied French in Calcutta, then took courses on China in Paris, ran a magazine in Hong Kong and ended up launching an online journal devoted to globalization at a venerable Ivy League institution. And in this engaging analysis, he answers such intriguing questions as" How did the coffee bean, first grown only in Ethiopia, end up in our coffee cups after a journey through Java and Colombia"
In examining these specific questions -- and larger ones about how the world is interconnected m Chanda does not emphasize his own experiences. But when appropriate, he effectively uses small, personal details to cut very big
A. was born in India
B. has worked in America
C. has worked in France
D. has studied in China -

In a sense, the new protectionism is not protectionism at all, at least not in the traditional sense of the term. The old protectionism referred only to trade-restricting and trade-expanding devices, such as the tariff or export subsidy. The new protectionism is much broader than this; it includes interventions into foreign trade but is not limited to them. (46) The new protectionism, in fact, refers to how the whole of government intervention into the private economy affects international trade. The emphasis on trade is still there, thus came the term" protection". But what is new is the realization that virtually all government activities can affect international economic relations.
(47) The emergence of the new protectionism in the Western world reflects the victory of the interventionist, or welfare economy over the market economy. Jab Tumiler writes, "The old protectionism…, coexisted, without any apparent intellectual difficulty w -

The prevailing theory of the universe’s origin, the "Big Bang" theory, says all matter and energy were once compressed into a tiny point.

"This glow, this radiation, is the oldest light in the universe. Imprin -

This year’s Sumantra Ghoshal Conference, held at London Business School, debated whether strategy research has become irrelevant to the practice of management. The late Mr Ghoshal published a paper in 2005 scolding business schools for pouring "bad theory" on their students. That same year Warren Bennis and James O’Toole, both at the University of Southern California, published an article in the Harvard Business Review criticising MBA programmes for paying too much attention to "scientific" research and not enough to what current and future managers actually needed. Business schools, they argued, would be better off acting more like their professional counterparts, such as medical or law schools, nurturing skilled practitioners as well as frequent publishers.
However, business school professors have a tendency not to change. Since universities take journal rankings into account when awarding tenure, academics are rewarded more when
A. business schools’ publishing papers
B. irrelevant management in business schools
C. too much efforts directed to research
D. MBA programmes’ misleading students
