Determination of sex by discriminant function analysis of postcranial skeletal measurements

Thieme and Schull [16] took measurements of seven postcranial traits from black skeletons of known sex to devise a method for accurately sexing human remains. With a linear discriminant function analysis of the data they obtained a 98.5% accuracy. The research reported here was designed to assess the accuracy of their method in the hands of other investigators using a sample of the same black population and its applicability to other populations of the same and different races. None of the samples used in this study were sexed with the same rate of accuracy either achieved or predicted by Thieme and Schull. However, two samples did reach 91% or better. Such results suggest that the methods employed have considerable value if used with appropriate precautions. Our multiple discriminant function analysis strongly indicates that neither side nor observer techniques affected the results. Sex accounts for a predominant fraction of the total variation among samples and race accounts for most of that remaining.     

Judicial Management of the Pretrial Process in Massive Litigation: Special Masters as Case Managers

This article reports on the experience of Special Masters appointed to regulate pretrial phases of a large civil antitrust suit. It describes techniques for expediting discovery, determining claims of privilege in production of documents, establishing stipulations of undisputed facts, and controlling and resolving disputes arising in discovery. It suggests a "managerial" approach to pretrial that is flexible and experimental and that may be useful in controlling the pretrial phase of other "big" cases.
