If you want to see what it takes to set up an entirely new financial center (and what is best avoided), head for Dubai. This flay, sun-baked patch of sand in the midst of a war-tom and isolated region started with few advantages other than a long tradition as a hub for Middle Eastern trade mutes.

But over the past few years Dubai has built a new financial center from nothing. Dozens of the world's leading financial institutions have opened offices in its new financial district, hoping to grab a portion of the $2 trillion-plus investment from the Gulf. Some say there is more hype than business, but few big firms m willing to risk missing out.

Dealmaking in Dubai centers around The Gate, a cube-shaped structure at the heart of the Dubai International Financial Centre (DIFC). A brainchild of the ruling Al-Maktoum family, the DIFC is a tax-free zone for wholesale financial services. Firms licensed for it are not approved to serve the local financial market. The DIFC aims to become the leading wholesale financial centre in the Gulf, offering one-stop shopping for everything from stocks to sukuk (Islamic) bonds, investment banking and insurance. In August the Dubai bourse made a bid for a big stake in OMX, a Scandinavian exchange operator that also sells trading technology to many of the world's exchanges.

Dubai may have generated the biggest splash thus far, but much of the Gulf region has seen a surge of activity in recent years. Record flows of petrodollars have enabled governments in the area to spend billions on infrastructure projects and development. Personal wealth too is growing rapidly. According to Capgemini and Merrill Lynch, the number of people in the Middle East with more than $1m in financial assets rose by nearly 12% last year, to 300,000.

Qatar, Bahrain and Abu Dhabi also have big aspirations for their financial hubs, though they keep a lower profile than Dubai. They, too, are trying to learn from more established financial centers what they must do to achieve the magic mix of transparent regulation, good infrastructure and low or no taxes. Some of the fiercest competition among them is for talent. Most English-speaking professionals have to be imported.

Each of the Gulf hubs, though, has its own distinct characteristics. Abu Dhabi is trying to present itself as a more cultured, less congested alternative to neighboring Dubai, and is building a huge Guggenheim museum. Energy-rich Qatar is an important hub for infrastructure finance, with ambitions to develop further business in wealth management, private equity, retail banking and insurance. Bahrain is well established in Islamic banking, but it is facing new competition from London, Kuala Lumpur and other hubs that have caught on to Islamic finance. "If you've got one siring to your bow and suddenly someone takes it away, you're in trouble," says Stuart Pearce of the Qatar Financial Centre about Bahrain

Saudi Arabia, by far the biggest economy in the Gulf, is creating a cluster of its own economic zones, including King Abdullah City, which is aimed at foreign investors seeking a presence in the country. Trying to cut down on the number of "suitcase bankers" who fly in from nearby centers rather than live in the country, the Saudis now require firms working with them to have local business licenses. Yet the bulk of the region's money is still flowing to established financial centers in Europe, America and other parts of Asia.

The financial hubs there offer lessons for aspiring centers in other parts of the developing world. Building the confidence of financial markets takes more than new skyscrapers, tax breaks and incentives. The DIFC, for instance, initially suffered from suspicions of government meddling and from a high turnover among senior executives. Trading on its stock market remains thin, and the government seems unwilling to float its most successful companies there. Making the desert bloom wa

B．thanks to the $2 trillion-plus investment from the Gulf.

C．from its past tradition as a trade center in the Gulf.

D．for it's a war-tom and isolated region in the world.

Sometimes I scratch my head when I read about the government&39; s efforts to improve schools:new standards and tests to be applied, strict teacher evaluations, and threats of school closures and job losses. They frighten the school employees, not to mention the students. Instead of making people unable to solve problems or try new ideas--which is what fear does to us--research on school reform. strongly suggests that policy-makers should encourage school leaders to take a more humane approach. In their study on the reform. efforts of twelve Chicago public schools, Bryk and Schneider found that enabling positive social relationships between the adults was the key to successful school improvement and that trust was at the heart of those relationships.

Trust in schools comes down to one thing:psychological safety or safety to speak one&39;s mind,to discuss with openness and honesty what is and isn&39; t working,to make collective decisions.

Yet this kind of safety doesn&39; t come easily to schools. According to Bryk and Schneider, the adults in school rely on each other to do their jobs correctly and with integrity （正直). The challeage is that our expectations are very diverse based on our unique backgrounds.

At one school where I taught, each teacher had different expectations about how much effort teachers should put into their work--a big difference between the teachers who left af~the last bell and those who worked into the evening. And when expectations are uncoasci or unspoken, it becomes impossible for others to live up to them.

We also make assumptions about the intentions behind a person&39; s behavior. As we all Imam,assumptions are often wrong. For example, parents and teachers my think the principal taml particular decision based on his career advancement rather than hat" s best for the studeata. don&39;t feel psychologically safe to question our assumptions and e~aecmtiatm, trust itiea am the window and our relationships suffer.
