To say that Khan Academy has important lessons to offer is to state the obvious. The Mountain View-based internet teaching institution—which has grown from founder Salman Khan’s individualized YouTube math lessons for his 7th grade niece to a worldwide phenomenon—offers thousands of free, plain-spoken online courses, from algebra to biology. But there are even broader lessons to be taken from the astounding success of Sal Khan, winner of the Manhattan Institute’s $100,000 2014 William E. Simon Prize for Lifetime Achievement in Social Entrepreneurship. Indeed, the lessons extend well beyond education.
In the past two decades, several campus poisoning incidents have sparked mass debates and concerns about students' psychological development and support.
Always wanted to be an author but not sure where to start? Have you considered self-publishing? Thanks to Amazon, you can. Kindle Direct Publishing allows you to get the word out via e-books, CreateSpacehelps you develop a print edition and ACX is the audio publishing division. I’ve used all three to develop my book.
The story of Khan Academy’s start and growth is dramatic. Sal Khan, New Orleans-born and MIT-educated, was working in the finance industry as a hedge fund analyst when, in 2004, he learned that his niece, Nadia, needed help with algebra. He began sending her his own clear, step-by-step illustrated lectures (Khan himself did not appear) via YouTube. That allowed other web users to use the same lessons. The teaching of Khan—a complete outsider to education or education reform—went viral, ultimately catching the eye of Bill Gates, whom Khan learned was helping his own children with lessons first meant for Nadia. Khan eventually attracted $15 million-plus in philanthropic support from the Bill and Melinda Gates Foundation,

Goldie Blox是一家玩具公司，使命是重新定义玩具商店中的“粉红走道”。在科学、技术、工程和数学（STEM）教育和职业领域，男性数量要大大多于女性，大部分女孩往往在八岁前就对这些领域失去了兴趣。Goldie Blox所设计的玩具则通过吸引女孩发展强大的口头及故事讲述能力的方式——同时仍提供机会来发展日后可转化成对工程学兴趣的技能——来鼓励和启发未来的工程师们。说到机会，一家玩具初创企业如何能在和一开始就统治着玩具行业的大公司的抗衡中脱颖而出呢？Goldie Blox走出了明智的一步：最近，该公司发布了一段视频，采用了Beastie Boys的歌曲《女孩们》（Girls）做背景音乐，该视频得到了病毒式传播。尽管这段视频最终被撤下，但Goldie Blox在提高公众对让更多女性和女孩对STEM产生兴趣——以及对Goldie Blox玩具——的认知上，做了一份相当不错的工作。

“Even if you have made your peace with a Fed rate rise there are other reasons to be nervous,” said David Hauner, head of emerging markets at Bank of America Merrill Lynch, who points to falling oil prices and the slowdown in China to illustrate why market volatility measured by the CBOE’s Vix index, a barometer of investor sentiment, has been elevated since August.
Many bosses hold their staff accountable, but the best show that they hold themselves accountable as well. This means adhering to the same guidelines they set for their employees and taking responsibility for both team successes and failures。
Rogers, unhappy with the turn of events, decided to leave the show after the first three seasons. The breach of contract led to a multi-million dollar lawsuit. Ironically, Wayne Rogers had never signed his contract to begin with (he had a problem with a morals clause). The lawsuit was thrown out. You could say Rogers got the last laugh, but since M·A·S·H went on for eight more seasons and Rogers' never reached the same career success again, the last laugh might be a relative concept.
The excitement was triggered by a Reuters story that cited documents about the potential transaction as the source of its information. Samsung actually has made at least one play for BlackBerry BBRY -19.77% before, in 2012. As to this latest rumor, the alleged takeover target was the first to refute that a deal is in the works.
Britney Spears continued her fall in the standings, after being knocked down from number 1 to number 5 in 2009, only to land at number 10 in 2010 as rising stars such as Lady Gaga and Justin Bieber become more prominent.

勉强能。民主党需要再赢得24个席位，这意味着他们需要守住特朗普去年胜选的全部12个民主党选区，并拿下23个在大选中投票支持希拉里克林顿(Hillary Clinton)的共和党选区，另外再添上一两个选区。算起来形势对民主党不利，但从历史先例来看形势有利于民主党。历任总统所在的政党几乎总会在中期选举时丢掉一些众议院席位，有时丢得还挺多，特别是当在位总统的支持率低于50%的时候。看一看2010年的巴拉克奥巴马(Barack Obama)就知道了。
As early as 2008, wearable technology—which can range in anything from measuring your heart rate to curating music based on your mood—has been touted as the next big moment in consumer electronics.

WASHINGTON (MarketWatch) — The U.S. economy finally got a big jolt of energy in 2014 after the lamest recovery since World War II. And 2015 is shaping up to be an even better year.
The civil service exam consists of writing tests and interviews. The interviews are expected to be held in February or March, after the writing test results come out in January.
Estimates vary, but the research firm IDC projects that wearable tech will exceed 19 million units this year—more than triple last year’s sales—and will soar to 111.9 million units by 2018. Credit Suisse values the industry at somewhere between $30 billion and $50 billion in the next two to four years. But before that happens, the nascent market has that pesky wouldn’t-be-caught-dead-wearing-it hurdle to clear.

They are also less likely to seek employment in a different sector after graduation. Only 30 per cent changed industry sector compared with nearly two-thirds of full-time MBA students.
Last year was the hottest on earth since record-keeping began in 1880, scientists reported on Friday, underscoring warnings about the risks of runaway greenhouse gas emissions and undermining claims by climate change contrarians that global warming had somehow stopped.
During the same period, Braziland Russia slashed their holdings to USD 261.7 billion and USD 108.9 billion,respectively.
At least 120 million American voters had been expected to cast votes in the race between the Democratic incumbent and Romney after a campaign focused on how to repair the ailing U.S. economy。
'Increased production in the U.S. meant that spot prices weren't reacting quite as much as in previous geopolitical incidents,' Mr. Hansen said. There is so much supply that threats to it have less impact than previously, and 2014 will be 'the first year in a while when supply growth is going to outpace demand growth,' Mr. Hansen said.

Most observers would think the single-aisle Comac C919’s first flight last May (pictured) is illustrative of this, but while it is a key milestone, it does not represent the whole story about what is happening in the industry. Two other events are much more telling.

不会。结束罗伯特穆加贝(Robert Mugabe)长达37年的执政（军方在这件事上也帮了点忙）后，埃默森姆南加古瓦(Emmerson Mnangagwa)承诺在2018年举行自由选举。这引出了一个问题：他可能会输掉大选。他至少要装作选举是公平的，因为他需要政治献金来扭转经济。这将意味着要推行选举改革——可能会让其不受欢迎的非洲民族联盟-爱国阵线(Zanu-PF)输掉选举。即使姆南加古瓦准备好在选举中赌一把，还不清楚军方愿不愿意。已经把自己的人推上台的津巴布韦将军们，不太可能会容许公众再把他踢下去。
“My manifesto with Summly was to get our technology into as many users’ hands as possible,” Mr D’Aloisio said, pointing to Yahoo’s hundreds of millions of users. “With Yahoo’s reputation as a content portal, we have an opportunity to fundamentally change the way content is consumed.”
At the forum, tech entrepreneurs also shared their views on virtual reality, which they said will be the most important computing platform over the next five to 10 years.
Contrary to the consensus view -- which assumes that smartphones in China will only get cheaper -- she cites research showing that the average selling price stablized last yearand has actually started to increase as Chinese users trade up to higher-quality smartphones.
Slow growth around the world won't hurt the U.S. all that much. American exports might flatten out or even dip, but that would be offset by lower imports of petroleum because of sinking oil prices. So the trade deficit is unlikely to get further out of whack.
The US has overtaken India as the leading user of anti-dumping and other trade defence cases, with China and its steel sector the biggest target, according to research.
