简言之,无叶风扇就是没有叶片的风扇。它的工作原理是先将空气吸入风扇基座内部,然后通过扇头环形上的洞将空气吹出。这款风扇据说是詹姆斯·戴森发明的,并命名为"气流倍增器"。就像可以飞行的喷气背包一样,无叶风扇被《时代周刊》评为"2009年度伟大发明"之一,同样它也不是世界上第一个无叶风扇。实际上,第一个无叶风扇于1981年被日本的东京芝区电力公司获得专利。尽管东京芝区电力公司的无叶风扇并没有用于生产制造,但詹姆斯的无叶风扇的原始设计与其设计相似,所以专利局拒绝授予詹姆斯这个专利。尽管授予东京芝区电力公司的专利已经过期,但在授予詹姆斯这项新专利之前,专利局需要他提供该设计的创新之处。詹姆斯的经理吉尔·斯密斯并没有否认这两种无叶风扇间的相似性,只是说两者间的差异在于所用"科技"不同。

Remedy: When we make a major decision such as accepting (or turning down) a job offer, we tend to exercise confirmation bias. If we think we made a good choice, we prioritize information that supports this view and if we fear we’ve made a mistake, we zero in on intel or impressions that reinforce this gut feeling. If you habitually doubt your competence when it comes to making career decisions, the issue is less about the subjective quality of your past choices and more about building confidence in your ability to guide your career in a satisfying direction and exert some degree of control over the outcomes of your choices. Addressing this could involve recalling the circumstances under which you made a particular choice and the priorities you held at the time and noting how they differ from the circumstances and priorities under which you’re evaluating those decisions. It could also involve working with a career coach to identify patterns in your decision-making and to help you bolster areas in which you’d like to increase your confidence – risk taking or negotiation, for example.

The S&P 500’s total return of 14% this year was 40% higher than its 25-year average annual gain.

A few characteristics made the U.S. stock market particularly difficult to keep up with this year.
Fifteen Chinese nationals have been charged with developing a fraud scheme in which they paid imposters to take entrance exams, including the SAT, and gained acceptance to elite American colleges and universities, the US Department of Justice said on Thursday.

One of the biggest trends I’m noticing in entrepreneurship right now focuses on access. Innovators are taking what was once costly, time-intensive, or otherwise beyond reach and efficiently offering it to consumers. Whether it’s learning new skills, inspiring a new interest, or tapping into formerly cost-prohibitive markets, entrepreneurs are finding new ways to bring the unique and specialized to a more mainstream market. We started to see this with collaborative consumption business models and I predict we’ll continue to see an influx of ‘access-based’ business models in the year ahead.

As a measure of that fall, 10 works have sold at auction for more than $100 million since 2004, and all of them were made by modern or contemporary artists in the past 120 years. Older paintings have seen their value, in relative terms, level off or decline. The trend was plain to see in recent weeks, as London’s auction houses tried to find buyers for their latest tranche of old masters. As has been the case in recent years, there were few works by major names.
