Thermocline

“A thermocline (sometimes metalimnion) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below. In the ocean, the thermocline may be thought of as an invisible blanket which separates the upper mixed layer from the calm deep water below.” http://en.wikipedia.org/wiki/Thermocline

I like to think of an octopus at night, reaching out when it gets chilly and arm by arm by arm by arm cuddling his invisible blanket around himself.

Air pollution in China: alpha/omega?

Useful and interesting discussion at China File on “airpocalypse now.”

Quote from Alex Wang to set up the discussion:

My own view is that China’s tipping point, in a sense, already arrived a few years ago. But the official response has been wholly inadequate to the task. Fundamental weaknesses in the way that China has approached its environmental protection efforts mean that the environmental crisis has continued to run amok.

Put all this in the “why I’m down on China” file, whose contents explain why my family will not be spending my 2013-14 sabbatical there.

Genentech: An Interview

I had the pleasure of speaking with Sally Smith Hughes recently about her book on the history of Genentech and the business of recombinant DNA technology. You can find our conversation here.

Attention is a resource

This piece at Marginal Revolution draws our attention once again to the ways in which being rich benefits the rich twice–once in terms of a direct access to wealth, and once in terms of how it allows the wealthy to preserve cognitive resources that allow them to make decisions that benefit their long-term self-interest.

Thus, SMS [the researchers] show that poverty (over)-stimulates attention to urgent problems which results in less attention given to important problems–thus, reduce some day to day urgencies and people may become more open to devoting attention to important problems like deworming or hygiene or paying the rent which would in the not-so-long-run result in greater benefits.

Crucially, notice that SMS’s experiments are about the effect of poverty not about the poor. In other words, at least some of our discussion of the poor may suffer from the fundamental attribution error.

That bit about fundamental attribution error seems crucial. And this sort of research, which we have seen more and more of in the last decade, seems to me to offer–via rationality and science–the best non-ethical, non-moral arguments for things like affirmative action that I can imagine being put forward. No idea if they’ll change anyone’s mind but it’s good to know, as always, that social science will help “prove” things that I have known all along were “true.”
