Primal–dual interior point methods and the HKM method in particular have been implemented in a number of software packages for semidef-inite programming. These methods have performed well in practice on small to medium sized SDP's. However, primal–dual codes have had some trouble in solving larger problems because of the storage requirements and required(More)

The authors describe suicide rates in Toronto and Ontario and methods used for suicide in Toronto for 5 years before and after enactment of Canadian gun control legislation in 1978. They also present data from San Diego, Calif., where state laws attempt to limit access to guns by certain psychiatric patients. Both sets of data indicate that gun control(More)
Eighty-five non-referred school children were divided into four groups based upon the IOWA Conners Teacher's Questionnaire: pure hyperactive (HYP), pure aggressive (AGG), mixed hyperactive/aggressive (HYP/AGG), and normal controls. The groups were compared on neurobehavioral tests believed to assess inattention and impulsivity. A continuous performance test(More)
