ABH antigen typing in bone tissue

Results obtained from the ABH grouping of bone tissues by the absorption-elution procedure and by a recently described two-dimensional absorption-inhibition procedure are reported. Neither the elution nor the inhibition procedure alone yielded uniformly correct results. A combination procedure consisting of the use of both absorption-elution and two-dimensional absorption-inhibition is proposed for bone ABH grouping. When elution and inhibition were used in combination, specimens yielding concordant results with both techniques were correctly grouped.     

Matching Judicial Supervision to Clients' Risk Status in Drug Court

This article reports outcomes from a program of experimental research evaluating the risk principle in drug courts. Prior studies revealed that participants who were high risk and had (a) antisocial personality disorder or (b) a prior history of drug abuse treatment performed better in drug court when scheduled to attend biweekly judicial status hearings in court. In contrast, participants who were low risk performed equivalently regardless of the court hearings schedule. This study prospectively matches drug court clients to the optimal schedule of court hearings based on an assessment of their risk status and compares outcomes to clients randomly assigned to the standard hearings schedule. Results confirmed that participants who were high risk and matched to biweekly hearings had better during-treatment outcomes than participants assigned to status hearings as usual. These findings provide confirmation of the risk principle in drug courts and yield practical information for enhancing the efficacy and cost-efficiency of drug courts.     

Cost and the calculus of voting

Downs's (1957) theory of voting maintains that individuals balance the costs of voting against anticipated benefits in deciding whether to vote. However, most empirical tests of his theory have concluded that costs play little role in individuals' decisions to vote or abstain, and that benefits are the determining factor. Unfortunately, the existing empirical tests of the theory have been inadequate, especially in regard to the measurement of the cost of voting. Using data from the Comparative State Elections Project, we develop an improved indicator of the cost of voting. When this measure of cost is used in a test of Down's theory, we find, contrary to most earlier research, that the cost of voting seems to be a more important determinant of participation than the factors associated with voting benefits in Downs's model.The authors shared equally in the research reported; the order in which they are listed was determined randomly.
