Autopoiesis, Structural Coupling and Cognition: A history of these and other notions in the Biology of Cognition

See on Scoop.itBounded Rationality and Beyond

Humberto Maturana. My intent in this essay is to reflect on the history of some biological notions such asautopoiesis, structural coupling, and cognition, that I have developed since the early 1960’s as a result of my work on visual perception and the organization of the living. No doubt I shall repeat things that I have said in other publications (Maturana & Varela, 1980, 1988), and I shall present notions that once they are said appear as obvious truisms. Moreover, I shall refine or expand the meaning of such notions, or even modify them. Yet, in any case, the reader is not invited to attend to the truisms, or to what seems to be obvious, rather he or she is invited to attend to the consequences that those notions entail for the understanding of cognition as a biological process. After all, explanations or  demonstrations always become self evident once they are understood and accepted, and the purpose of this essay is the expansion of understanding in all dimensions of human existence.

When did same-sex marriage laws become effective by state? – Decision Science News

See on Scoop.itBounded Rationality and Beyond

We thought we’d look when various states allowed same-sex couples to marry (if they did at all) before today.

In light of the good news today that the Supreme Court ruled that same-sex couples have the right to marry in the United States, we thought we’d look at when same-sex marriage laws became effective by state (if they did at all) before today.

Noting that same sex marriage is a dividing issue between the left and right in the US, we thought we’d compare the date of when same-sex marriage laws become effective in each state with each state’s Republican (two-party) vote share in 2012. Results are above.

Note that California’s same-sex marriage law was effective in 2008, then it was overturned, and then made effective again in 2013. We went with the earlier date because you’ve got to chose something.

The next question is “what about the states that were added by the Supreme Court decision today”? We made a second plot, below, in which we put today’s date for those states in the “effective date” column. The result is pretty much the same.
