母亲生命线

伊斯兰堡—上个月,牛津大学格林坦普顿学院(GTC)在艾格洛夫公园(Egrove Park)召开了一年一度的新兴市场研讨会。今年的主题是“母婴健康和营养”。学院学者史蒂芬·肯尼迪(Stephen Kennedy)在开幕致辞的最后演示了一张卡通幻灯片,上面画着两个年轻的选手正在开始一场竞赛:其中一位强壮而健康,另一位又瘦又弱,被束缚着手脚,身患沉疴,还饱受营养不良困扰。潜台词显而易见:并非所有人生而具有平等的成功机会。

当然,这算不上什么突破性洞见。贫困、母亲文化水平、卫生和儿童健康的家庭条件等因素的影响及其反过来对社会和经济结果的冲击一目了然。问题在于这些因素是无法通过孤立的公共卫生干预解决的。但另一个讨论较少的社会决定因素——母亲的营养可以。

自希波克拉底时代以来,人们一直在讨论“先天”和“后天”如何相互影响以决定一个人的发展。事实上,即使在古代文明中,充足的母亲营养也被认为是确保下一代生存和繁荣的关键因素。但贫困和无知可以让最好的初衷化为泡影。

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
