Twins' IQs: a reply to Schwartz and Schwartz.

It is argued that the criticisms by Schwartz and Schwartz of Jensen's analysis of IQ data on monozygotic twins reared apart fall down on two central points, methodological and theoretical: (a) Valid inferences concerning the broad heritability of intelligence can be drawn from analysis of the combined data from several independent studies of MZ twins reared apart, even though the groups differ ...

A counterexample to a conjecture of Schwartz

In 1990, motivated by applications in the social sciences, Thomas Schwartz made a conjecture about tournaments which would have had numerous attractive consequences. In particular, it implied that there is no tournament with a partition A,B of its vertex set, such that every transitive subset of A is in the out-neighbour set of some vertex in B, and vice versa. But in fact there is such a tourn...

LFA-1 activation plays a major role in reducing the velocity of rolling leukocytes and causing firm adhesion to the endothelium. The signaling cascades that cause LFA-1 activation during this process have been described through mostly correlative experiments, but the precise occurrence and location of LFA-1 activation in response to specific signals has not been directly shown. Tim Springer’s g...
