Postponing parenthood beyond the teen years can improve child wellbeing by increasing the odds of a healthy birth. Compared to older mothers, teen mothers were less likely to receive prenatal care, more likely to smoke during pregnancy, and more likely to have a birth that is preterm and/or low-birthweight. Consequently, teen mothers also experience higher rates of infant mortality, and infants...

The purpose of this note is to posit and discuss the concept of "competitive inhibition potential" (CIP), which is an in vivo index of the ability of a competitive inhibitor to elevate plasma concentrations of drug substrates, when the competitive inhibitor is administered at its usual and customary dose.

W hen will it be done? " Senior managers will ask their software project managers this question more than 250,000 times this year.

However, when you consider Barry Boehm's claim that early software life-cycle estimates vary by a factor of four (25 to 400 ...

Quantitative scaling into percent signal change is helpful to detect and eliminate “bad” results with abnormal extreme values. While cognitive effects give signal changes on the order of 1% (and larger in the visual and auditory cortices), signal variations of over 10% may arise from motion and other artifacts in the data. Thus, a quantitative check on measured effect size can be used to screen...
