Fairs, carnivals, festivals or anywhere you can buy helium-filled balloons, you’re sure to see at least one balloon rising into the sky after someone accidentally lets it go off.在集市,嘉年华,节日聚会还有任何其他地方你都能买到氢气球,你至少能看到一个气球由于有人没有拿好,意外让气球飞向高空的情况。What happens to the balloon after it rises out of sight? Well,that depends on how high the balloon goes!气球飞到看不见的地方会发生什么呢?嗯,这取决于气球飞到多高的地方!When you inflate a balloon, you’re actually putting gases, mostly helium,in this case , into an elastic container. As you add more gas, the pressure inside the balloon increases, and in response, the balloon expands…up to a point, that is! If you put in too much helium, and the pressure inside the balloon gets too much higher than the atmospheric pressure on the outside of the balloon, the balloon will burst.当你给气球充气的时候,你充的一定是气体,大多是氢气,到一个有弹性的容器内。你加入的气体越多,气球内部的压力也随之增长,相应地,气球变大了……到了一定的大小,就是那个状态下,如果你充入更多的氢气,气球内部的压力就比气球外面的大气中的压力大,气球就会保障。So what happens to a rising balloon? Well, if it gets caught by an air current and is carried along level to the earth’s surface, it could go a long way,even across the ocean,if the winds arrived! Of course, no balloon is perfectly sealed, no matter how tightly you tie it, so eventually the helium will leak out, and the balloon will sink.所以一个不断向上升的气球会怎么样呢?嗯,如果它遇到气流被带到地球表面,这样可以走很远。如果有风,它甚至可以越过海洋!当然,不论怎么扎紧气球,没有气球是完全不会漏气的。因此最终氢气会泄露,气球会下沉。 /201206/186183。

Theoretically the federal reserve is independent of the president and the executive branch of government, but president do appoint the chairman of the fed, so it matters to you and your money who sits in that seat. Alan Blinder is a professor of economics at Princeton University, he is a former federal reserve vice chairman, thank you for joining us, sir, its good to see you, lets talk about Ben Bernankes fed, has it have more influence on our economy? Has this fed have more influence on our market and economy than the feds mission would dictate that it has?理论上,美联储独立于总统和行政政府机构,这一职位却是由美国总统任命的。因此,到底谁来做这个座子?这可事关重大,事关口袋中的钱。艾伦#8226;布林德是普林斯顿大学的一名经济学教授,美联储前副主席,感谢您参加我们的栏目,很高兴看到您。让我们谈一谈伯克南的美联储,是否对美国的经济产生了重大影响?美联储对市场和经济的影响是否比美联储使命所赋予它的还要大?Well, thats a hard question to answer, you know because the feds mission is to promote maximum employment and stable prices, as you just said the price level the inflation rate has been very stable over the Bernanke era as it was in the later part of Greenspan era, the fed has been working overtime so to speak both figuratively and literally on its employment mandate and it still is, whats clear is its been very activist by historical standard absolutely.嗯,这是一个很难回答的问题,因为美联储的使命是促成实现最大就业以及稳定物价。如您所说,在伯克南在任时期,物价水平,通货膨胀率已经非常稳定了,如同格林斯潘时代后期。由于美联储一直以来的努力工作,无论从数字上还是从实际上来说,而且从绝对意义的历史标准上看,很清楚,其就业政策相当激进。When you say activist you know some people call mission creep other say that its doing that because it has the effectiveness, its able to do it where congress doesnt do it, whats your sense on should congress be doing more of the work the fed is trying to achieve?当您说激进时,有人称其为“使命偏离”还有人认为美联储这样做是因为这种政策有效,美联储有能力这么做,然而国会没有能力。对于美联储正在努力实现的目标,国会是否应该承担更多工作?对于这一问题,您如何看待?Congress should be doing more of the work the fed is trying to achieve, look, the reason the fed has been pulling so many different levers over the last several years is that its interest its normal weapon the short term interest rates, the federal fund rates hit virtually zero all the way back in December 2008, at that point the Bernanke fed could have said we give up, we are closing up shop, thats all we can do, I think that would be a huge mistake, or it could try to look for other things it can do, such as this various quantitative easing and other things that the fed has put into effect, thats the course it took, i think thats the right course, it doesnt mean you cut every little detail always, but it was basically the right course, and frankly the job might have been a little easier or might a lot easier if congress was more cooperative, i dont mean cooperative with the fed, I mean more cooperative with the president and getting things done such as for example the jobs act the president proposed a year ago and other things like that, rather than letting this thing go or basically leaving it to Ben Bernanke.对于美联储正在努力实现的目标,国会应该承担更多工作。原因在于,美联储在过去几年采取了各种手段,其中最常用的武器就是利率,短期利率,联邦基金利率一路降到2008年12月的零利率。在这一程度上,伯克南美联储本来可以说,放弃吧,我们把该关的商店都关了,这就是我们所能做的了。我认为那样做的话,将是一个大错误。或许它还可能做些能做的其他事情。比如各种定量宽松政策以及美联储已经采取的其他各项措施。这就是美联储这几年所选择的道路,我认为这是一条方向正确的道路,它不仅仅意味着你总是关闭小型零售店,而是因为它大体上是正确的方向。坦白地说,如果国会更加合作,就业情况会有一些好转,或者许多好转。我不说国会与美联储合作,我是说国会与总统更加合作,以推进诸如总统一年前提议的工作法案以及其他类似法案,而不是置之不理,基本上留给伯南克处理。201211/210222。

The Importance of Hand Washing洗手很重要In a recent study of people passing through major U.S. airports, it turned out that about thirty percent werent washing their hands after using the bathroom.近日,一项调查发现,30%美国主要机场出入的乘客们表示便后不洗手。These people who dont wash their hands dont just keep them in their pockets. They walk around shaking other peoples hands, holding babies, and handling food and doorknobs.而这些乘客不会老实地双手插袋,和其他人握手,抱抱小孩,处理食物,开关门……So basically, these folks are running around exposing the fastidious hand washers among us to infections that can range from the pesky common cold to SARS, which can be fatal. After all, many infections are transmitted through hand-to-hand contact.基本上,就是因为这些人不洗手,成为了疾病的媒介,从麻烦的感冒到可以致命的传染性非典型肺炎SARS。毕竟不少疾病都是握手接触传播的。Whats interesting is that people tend to exaggerate when theyre asked about hand-washing. In surveys, ninety-five percent of people claim to wash their hands every time, when the actual observed percentage is much lower.有趣的是受访者还会“夸大其词”。研究表示,95%的人声称每次都会洗手;而观察到的数据却小得多。So think about the fact that only around seventy-five percent of people claim to wash their hands after sneezing or coughing!想想事实上,有大概75%的人声称会在打喷嚏后洗手。The actual number is there much lower, too. Um?那么,事实上的洗手的人微乎其微了。Probably. On the bright side, since the SARS outbreak in Toronto, hand-washing rates at the airport have been near to one hundred percent. So all it takes to get people scrubbingdiligently is a major epidemic.极有可能,但是值得庆幸的是,在SARS在多伦多爆发后,机场洗手率高达百分之百。所以全民“勤奋”地洗手全靠“传染病”了。 /201211/209803。

The Surprising Truth: Doctors Are Not Washing Their HandsSince the beginning of time, or at least for a good long while, mothers have exhorted their kids to wash their hands. It’s a lesson most of us learn and carry with us into adulthood.And you’d think that some people namely, doctors, nurses, and other healthcare workers would heed this most basic tenet of proper hygiene most of all.Because, after all, hand washing is the most effective way of not sping germs.But according to dozens of studies, doctors are not so great when it comes to hand washing. Sure, surgeons are very careful about scrubbing up.But other docs are less vigilant about washing their hands before and after seeing patients. So over the past several years researchers have thought hard about how to get doctors to maintain better hand hygiene.One study found that placing carefully worded signs next to soap and hand sanitizer dispensers helped.Because doctors and other healthcare workers tend to believe that they won’t get sick, the study found that the most effective signs were those that emphasized the benefit for patients when doctors wash their hands.Another study found that training cameras on sinks and hand sanitizer units, and publicly reporting how often doctors and nurses washed up, significantly increased hand washing rates.It’s not clear why, exactly, doctors aren’t normally more vigilant about hand washing. But the importance of hand hygiene is clear.Sping diseases is one of the biggest problems in hospitals. And regular hand washing is one simple, if apparently difficult to enforce, solution. /201205/184072。
