Violent victimization and involvement in delinquency: Examining predictions from general strain theory

In a recent critique and elaboration of general strain theory, Agnew (2001) argued that criminal victimization might be among the most consequential strains experienced by adolescents, and therefore might be an important cause of delinquency. Few studies to date, however, had examined victimization as a potential cause—rather than outcome—of delinquency. This article addresses this void by examining predictions from general strain theory about the effects of victimization on later involvement in delinquency. The analyses indicated that violent victimization significantly predicted later involvement in delinquency, even when controlling for the individual's earlier involvement in delinquency. Moreover, general strain theory appears to be a useful theoretical framework for examining this relationship. The effects of victimization on delinquency were explained in part by its effects on anger (the key intervening variable specified by the theory). Partial support also emerged for the theory's hypothesis that the effects of strain should be conditional upon other factors. Specifically, the effects of victimization were marginally greater for juveniles with weak emotional attachment to their parents and significantly greater for those low in self-control.     

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.     

Statistical analysis of the measurement errors in the determination of fragment length in DNA-RFLP analysis.

DNA from human whole blood samples was digested with the restriction enzyme HinfI and RFLP analysis performed using the single locus probes MS1, MS31, MS43a and YNH24. The intergel variation of 3291 duplicate measurements of fragment lengths in terms of basepairs was investigated. The difference between two measurements of the same fragment on different gels increased approximately exponentially with increasing fragment length. After transformation of the fragment length into a normalized migration distance it was found that the difference between two transformed measurements was normally distributed with a S.D. (0.70 mm) which was independent of the fragment length. The errors of band 1 and band 2 on the same lane were correlated (r2 = 0.8). It is useful in the calculation of frequencies and in retrieval procedures and also in the calculation of likelihood ratios to be able to use a S.D. which is independent of the fragment length.     

Traumatic transection. An unusual fatal pedestrian injury.

Speed, alcohol, and pedestrian injuries constitute disturbing components of the spectrum of trauma in the developing world. The complete fatal transection of a pedestrian, at the level of the lower abdomen, by an oncoming automobile traveling at high speed is described. The upper torso was found inside the vehicle, whereas the lower torso was projected some distance ahead, onto the highway. An accident analysis, in order to ascertain the speed of the automobile, is demonstrated and the biodynamic mechanisms of this injury are discussed. The nature of this injury is compared with that of traumatic hemipelvectomy following which survival has been reported.     

Toxicological findings in military aircraft fatalities from 1986-1990.

Toxicological findings in all military aircraft fatalities investigated by the Division of Forensic Toxicology at the Armed Forces Institute of Pathology from 1986-1990 are presented. Carbon monoxide saturation levels greater than 10% were found in 4% of the 535 cases where appropriate specimens were collected. Positive ethanol findings were more indicative of postmortem formation than antemortem consumption. In only 1 case were abused drugs (cannabinoids in a passenger) detected. Other drugs identified included nicotine, chloroquine and over-the-counter analgesic agents, antihistamines and sympathomimetic drugs.
