美国总统巴拉克·奥巴马6月4日在埃及开罗大学发表讲话,阐明美国致力于寻求与穆斯林国家关系的新开端。以下是讲话文字记录中译文,由美国国际信息局(IIP)翻译。

2009年6月4日
奥巴马总统:非常感谢你们。下午好。我荣幸地来到永恒的开罗古城,荣幸地受到两所著名学府的邀请。爱资哈尔(Al-Azhar)一千多年来一直是一座伊斯兰学术的灯塔,开罗大学(Cairo
University)一百多年来一直是埃及发展的源泉。你们并肩而立,象征着传统与进步的和谐共进。我对你们的盛情邀请,对埃及人民的盛情邀请表示感谢。我也自豪地带来美国人民的友好情谊,带来我国穆斯林民众的平安问候:
“Assalaamu alaykum.”('愿你平安。')
我们相聚在美国和穆斯林世界之间关系十分紧张的时期──这种紧张关系的历史根源远远超出了当前的任何政策辩论。伊斯兰教与西方世界之间的关系史既包括好几个世纪的共存与合作

“量化宽松”货币政策助涨商品价格

量化宽松货币政策
2009/03/02 11:42 P.M.
量化宽松(quantitative easing),俗称“印钞票”,是由日本央行于2001年提出,指央行向银行体系注入超额资金,让基准利率维持在零。包括大量印钞或者买入政府、企业债券等。
央行可以通过两种方式放松银根:改变货币价格(即利率)或改变货币数量。多年以来,正统的货币政策一直以前一个政策杠杆为中心。然而,随着通胀率回落、短期名义利率逼近零点,从原则上说,央行可以后一种方式、即数量杠杆来实施扩张性货币政策。影响经济活动的是实际利率而非名义利率。如果经济处于通缩状态,那么即使名义利率为零,实际利率也会保持正值。
摧毁华尔街的秘密数学公式

长城伟业 康兰
从上世纪80年代中期起,华尔街就开始依赖金融工程精英们来创造各种新的获利途径。他们创造金钱的方法一直成功运转了这么多年,直到其中一种“突然”引发了这场全球性的经济灾难。
一年前,人们总认为像李祥林(David X.
Li)这样的数学天才可能会在某日得到诺贝尔奖的眷顾,因为金融经济学者,甚至华尔街的这类人才的确此前也获得过诺贝尔经济学奖。李祥林的开创性工作是衡量投资风险,而在金融领域,他的成果与以前获得过诺贝尔奖的学者的贡献相比更有影响力、更快速地得到广泛应用。然而,当晕头转向的银行家、政治家、监管者和投资者在这场自“大萧条”以来最严重的金融大崩溃的废墟中寻找事发根源时,他可能更应该庆幸的是自己还有一份金融业的工作。
李祥林从事的研究是确定资产间的相关性(correlation),也就是将一些完全不同的事件之间的关联度用数学模型来量化。这是金融领域中的一大难题,但他构建的被称为高斯相依函数的公式能以数学手段令极其复杂的风险比以

目前,金融工程师(financail
engineer)的称谓越来越多的被QUANT所代替。下面这篇文章以浅显的语言介绍了QUANT的方方面面。
随着国内金融市场的发展,相信会有更多的金融机构开始招募QUANT.

Meeting the U.S. Financing Needs
PrintShare
Delicious Digg Facebook reddit Technorati Mikka Pineda, Rachel
Ziemba and Arpitha Bykere | Feb 18, 2009
Bank rescue via TARP funds, the bailout of the GSEs and two fiscal
stimulus packages have put severe pressure on the U.S. fiscal
deficit since 2008. Despite having little bang for the buck in the
short-term, the recently passed $787 bn fiscal stimulus package
will have a bill of $185 bn in FY2009 and $399 bn in FY2010 (based
on Congressional Budget Office estimates), adding to the U.S.
governments financing needs. Given further downside risks to growth
and bank losses, another stimulus package and more funds for bank
recapitalization will be required during 2009-10. After a deficit
of $455 bn in FY2008, these expenditures will push the U.S. fiscal
deficit to $1.6-1.8 trillion in FY2009 (already $569 bn in Oct
2008-Jan 2009) and over a trillion in FY2010. This along with

原文在这:
The Problem: The US electricity transmission and distribution
system – or ‘grid’ -- is in critical need of an upgrade. It is old,
balkanized and too limited in its reach. The current grid is a
series of independently operating regional grids – it can’t meet
the needs of a nation whose economy would benefit substantially
from the system optimization that comes with national
interconnection. Its limitations and vulnerability to failure are
also reported to cost the nation $80 billion to $188 billion per
year in losses due to grid-related power outages and power quality
issues.1 And most critical to clean energy development, areas rich
in renewable resources like solar, wind and geothermal are
currently not well-served and thus have no ‘highway’ available to
move power outputs to the markets where that pow
