长春市五马路妇产医院女子妇科医院怎么样吉林长春第四医院几点下班Well, weve all been hearing about ongoing Mars exploration, and how water probably used to be abundant there. And a water spewing volcano was recently discovered on a small moon orbiting Saturn. Water is one sign that life may exist or have existed at some point.我们总会听到一些关于火星探测以及火星以前含有大量水资源的事情。最近,科学家又在一颗绕土星转动的小卫星上发现了一座喷水火山。水的存在就说明这里存在生命或曾经存在过生命。Sugar糖Astronomers have discovered sugar molecules floating in gas surrounding a young star about 400 million light years away. Not sugar as in the stuff in those little packets, mind you. Were talking about carbohydrates simple molecules made of carbon, hydrogen, and oxygen which are the simplest forms of sugar.天文学家在围绕一颗年轻恒星4亿光年外的气体上发现有糖分子浮在其中。这里的糖可不是我们说的那种用糖纸包的糖哦。我们所说的是由糖的最基本形式---碳、氢、氧所组成的碳水化合物简单分子。But the simple sugars that the astronomers detected, called glycoaldehydes, are thought to be one of the building blocks of life.但是天文学家发现的这种叫做甘油醛的单糖被认为是生命的重要组成部分之一。How Do These Simple Sugars Form In Space?这些单糖是如何在宇宙间形成的呢?Scientists suspect that they form on ice covered dust grains in interstellar clouds. The really exciting thing is that discovering these molecules near a sun like star means that the basic building blocks of life may be present around new stars even before planets form.科学家们猜测它们是在星际星云中由冰包裹的尘土颗粒上形成的。真正让人兴奋的是,在太阳这样的恒星附近发现这些分子意味着生命的基本组成部分在星球形成以前就已经出现在新星周围了。Again, this doesnt prove anything, but its one more clue about how life might have begun on Earth–and how and why it might exist elsewhere in the universe.虽然这还是不足以明什么,但这对于人们了解地球上是如何出现生命的以及如何、为什么宇宙的其他地方也可能出现生命提供了线索。 /201304/236939双辽儿童医院几点开门 Off the East Coast, Australia, up to 200 kilometers off shore, a line of surf rises out of the open ocean. 澳大利亚东海岸之外,200公里的近海之内,宽广的海面上一层层浪花翻腾。Beneath the surface, creating these breaking waves is the most magical marine environment on Earth.在这海面之下,形成这些波浪的正是这个地球上最奇幻的海洋生境。;Im Monty Halls, Im a marine biologist and diver, and Ive always been fascinated by the sea. 我是蒙蒂胡奥斯,一名海洋生物学家兼潜水员。我一直对海洋着迷。For me, theres always been one place that is the epitome of everything that is wonderful about the marine environment. 对我而言,总有一个地方,浓缩了海洋所有的美丽。Its a true, global icon. Its a Mecca for anyone whos ever heard the word coral-the Great Barrier Reef.;这是一个真正的圣地,就像麦加对于穆斯林一样,大堡礁!Stretching for over 2,000 kilometers up the tropical coast of Australia, it is quite simply the largest living structure on the planet. 长达2000公里的澳大利亚热带海岸线,是地球上最大的生命聚集地。Its made up of almost 3,000 different reefs, each one with a different personality. 这里有3000多种珊瑚礁,每一种都各有特性。And its so much more than just coral. 出名的不仅仅是珊瑚。But the Great Barrier Reef is most famous for its underwater world. 大堡礁最著名的是她的海底世界。Here, there is more life than almost anywhere else on Earth.这里有比世界上任何其他地方都丰富的物种。201408/321049辽源妇女儿童医院网上咨询热线

吉林省长春市二院在线询问Business商业报道Golden parachutes金色降落伞Rip-cord economics打开经济降落伞Pay-offs for the boss need to be better designed企业老板薪酬结构须改善RICH rewards for departing bosses are not popular.离职的老板还领着厚饷总让人难以接受。After Sir Fred Goodwin led Royal Bank of Scotland into a ditch and dumped the bill on British taxpayers, he left with a pension of over £700,000 a year.弗雷德?古德温爵士把苏格兰皇家推进深坑,继而用英国纳税人的真金白银买单走人之后,居然每年还享有70万英镑的退休金。The Sun, a tabloid, said he had screwed the nation.英国小报太阳报直陈其把整个国家都搞砸了。Yet golden parachutes have their uses.不过金色降落伞条款也并非一无是处。 If well-designed, they align the bosss interests more closely with those of shareholders.如果妥善拟备该等条款,老板的利益会更紧密地和股东利益协调一致。Suppose, for example, a takeover is brewing.例如,在拟收购的项目中,该等条款的作用就可见一斑。Takeovers are usually lucrative for shareholders of the target firm:对于目标公司的股东而言,收购通常会带来丰厚回报:in America between 1990 and 2008, they have received a median premium of 35%. But the bosss interests are quite different.在美国1990年至2008年间的收购项目中,目标公司股东的收益溢价中值为35%。If the firm is acquired, he is likely to be fired.但老板的权益相去甚远;如果公司最终被收购,其可能官位难保。A golden parachute can persuade the boss not to obstruct a takeover.妥善的金色降落伞条款可促使老板不为收购设置障碍。But their notoriety dissuades firms from using them.但鉴于该条款通常不受欢迎,公司不太会动用。Dirk Jenter of Stanford University and Katharina Lewellen of Tuck Business School find that golden parachutes are rarer and stingier than they should be.斯坦福大学的德克?珍特和塔克商学院的卡特琳娜?卢埃林研究认为:金色降落伞条款不应该像现在这般罕见且苛刻。To test whether bosses block takeovers, they looked at what happens when they are nearing retirement, and therefore have no future career to sacrifice.为核查企业老板是否会因其自身原因选择阻碍收购,这两位学者研究了临近退休的老板会如何处理收购项目。Using data on American public firms from 1992 to 2008, they found that companies with a boss aged 65 or over were 50% more likely to be taken over.他们分析了1992年至2008年美国上市公司的数据,结果显示:老板年龄在65岁以上的公司被收购的可能性高出50%。Another paper, by Eliezer Fich and Ralph Walkling of Drexel University and Anh Tran of Cass Business School,德雷塞尔大学的埃利泽?芬奇、拉尔夫?沃克林与卡斯商学院的陈安在一篇共同发表的论文中指出:found that when golden parachutes are larger, proposed mergers are more likely to be completed,如果金色降落伞的力度增强,拟合并项目达成的可能性更大,but buyers pay less for the shares of the target firm.但买方就目标公司股份所付的对价则减少。The data from Mr Jenter and Ms Lewellen show that when the boss of the target firm is old, buyers pay an average premium of 26%.珍特与卢埃林的统计数据显示:如果目标公司的老板年届退休,买方付的平均溢价为26%;For younger bosses, the premium is 33%.而对于老板年龄较轻的公司,则为33%。This makes sense. If younger bosses are more reluctant to sell, it will cost more to overcome their objections.这就说明了问题所在:年轻的老板相对不太愿意售出其公司,所以买方须付更高溢价以平息其反对意见。So boards must strike a balance.所以,董事会必须寻求一种平衡。If the bosss golden parachute is too miserly, he may block a deal that would benefit shareholders.若金色降落伞条款对企业老板过于不利,其可能会干预对股东有利的交易;If it is too generous, he may fail to negotiate hard with potential buyers.反之,若金色降落伞条款对其过于优厚,其可能不愿尽心尽力与拟收购方谈判。As with real parachutes, poor design can have serious consequences.跟真正的降落伞一样,劣质的金色降落伞所带来的后果可能不堪设想。 /201305/239696辽源中医院剖腹产怎么样 长春哪家的人流做的好
