The Sunday roundup

Actually published on Monday because I slept through a great deal of Sunday.
1. In case you somehow missed it, Singapore’s founding father Lee Kuan Yew died at 91. Some of the best pieces from BBC (and another from BBC), The Economist, personal reflections, and others.
2. Who is an expat and who is an immigrant (and who is a guest worker and who is an intruder)? Two commentaries on this from the Guardian and the WSJ. (Both are somewhat context-driven. Neither one fully captures the intricacies of how race, skin colour, and socioeconomic class interact. After centuries of colonialism the world is still coming out from under that long shadow.)
3. Also from the WSJ, for expat marriages, breaking up is harder to do. Note: The WSJ is the paper that once thought a middle-class family income was $650,000, so you ought not to be surprised when they entirely fail to consider what impact financial strain can have on the marriages of the transnational poor.

4. An important reminder on learning and teaching for competence, not grades, from Duke-NUS professor Ranga Krishnan who trains some of the country’s doctors-to-be. Grades, as a snapshot of a student’s learning curved against his peers’ at any single point in time, are a poor proxy for lifetime competence.
