One way is for citizens to receive vouchers that they can use to pay for training.

一个方法是向国民发放抵用券，可用于支付培训费用。

One of the findings: those who received a voucher had better mental health outcomes – such as lower rates of depression – than those who didn’t.

其中一项发现：获得代金券的人比没有代金券的人有更好的心理健康结果——比如抑郁症的发生率更低。

In this study, we're testing whether the women of Kibera are happier and more productive after they receive vouchers for time-saving services (meals and laundry) than after receiving vouchers for non-time-saving goods (ingredients for meals).

在这项研究中，我们正在测试基贝拉的女性在收到省时服务（膳食和洗衣）代金券后是否比收到非省时商品（膳食原料）代金券后更快乐、更有效率。
