Notes: Abstract Data on variation in eight polymorphic marker systems and some psychometric traits collected for other purposes in a group of Oxfordshire villages were examined for possible associations. Of a number that appeared statistically significant, one between haptoglobin and aspects of Wechsler Adult Intelligence Scale (WAIS) IQ seemed particularly interesting, since the haptoglobin variation is also associated with “within-family” social mobility. After using a multiple regression approach to allow for the possible effects on IQ of sex, geographical location, social class, and family structure, the association between haptoglobin and performance IQ became even stronger. This procedure removed the evidence for all the other associations except for one between Kell blood group and IQ. When the haptoglobin variation was examined in relation to the component subtests of the WAIS, the association turned out to arise entirely from the block design element.

Notes: The frequency dependence of the complex-shear modulus of a nonbrominated flame-retardant polycarbonate has been successfully represented from 1 hertz (hz) to 1 gigahertz (ghz) at 190°C using a mechanical analog of the Cole-Cole dielectric analysis. Two sets of retardation times were required centered about 74 msec and 16 μsec. The β value for the short time response was 0.83 and for the longer time response was 0.58. The values of JoN determined from the common point at which the terminal-zone arc and the transition-zone arc touch the Jc″ = 0 axis yields an entanglement molecular weight, Me, of 1470 g/mole.
