脊髓灰质炎英雄

西雅图—世界在遏制脊髓灰质炎方面的进步也许是全球卫生事业中保守最好的秘密。事实上,我的2015年英雄正是战斗在遏制这一疾病最前线的男性和女性。

1988年以来,全世界每年发生的脊髓灰质炎病例下降了99.9%以上。曾几何时,这种疾病每年都会导致大约350,000儿童瘫痪;而在2015年,脊髓灰质炎致瘫病例只发生了不到100例。

此外,2015年还标志着我们消灭这一致瘫病因的又一重要里程碑:人类历史上第一次,非洲一整年都没有发生一例小儿麻痹症。

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.
