Estimating body mass in subadult human skeletons.

abstract：:The relationship between psychological stress and reduced fecundity has been a matter of speculation and investigation for decades. Most previous studies have been compromised, however, by a number of problems including ambiguous direction of causation, poorly operationalized variables, and the confounding of psycholo...
