Instructing jurors

This field experiment examines the advantages and disadvantages of two jury instruction procedures: instructing the jury prior to the evidence portion of the trial and providing the jury with a written copy of the judge's instructions to take with them to their deliberations. The presence or absence of both procedures was randomly assigned to 34 civil and 33 criminal trials in Wisconsin circuit courts. Following the trials, questionnaires were administered to judges, lawyers, and jurors. Overall, the findings do not provide any support for the hypotheses that written instructions would help the jurors to recall the judge's instructions, that they would increase the jurors' satisfaction with the trial, or that they would shorten the trial. The written copy did appear to reduce disputes among jurors about the judge's instructions. No evidence was found to support the notion that written instructions would reduce the amount of time that juries devoted to the evidence, that they would lengthen deliberations, or that they would place excessive demands on the resources of the court. The findings also did not support the hypotheses that preliminary instructions would assist the jurors with recall of the judge's instructions or the evidence, or that they would reduce juror confusion about the trial procedure, but did support the hypotheses that preliminary instructions would assist the jurors with following legal guidelines in their decision making and would increase the jurors' satisfaction with the trial process. No evidence was found to support the hypotheses that preliminary instructions would be an impractical procedure or that they would place excessive demands on the judge.Northwestern University     

Relationship Between Childhood Sexual Abuse Characteristics and Dissociation Among Women in Therapy

This study investigated the relationship between 10 characteristics of childhood sexual abuse and dissociation in adulthood. A structured clinical interview, the Dissociative Experiences Scale, and the Dissociation Subscale of the Symptom Checklist 90 - Revised were administered to 118 women survivors seeking psychotherapy. Separate stepwise multiple regression analyses were conducted for each dissociation scale to determine which abuse characteristics were predictive of dissociation. In both analyses, the same four variables were significantly related to dissociation: age at onset, coercive sexual acts, objectifying sexual acts, and concurrent multiple perpetrators. Implications of findings for future research and clinical practice are explored.     

Analytical profile of 4-methylthioamphetamine (4-MTA), a new street drug

The analytical properties for a new street drug, 4-methylthioamphetamine (4-MTA), are presented. This new compound was found in tablets sold on the illicit market in the Netherlands and Switzerland in 1997 and 1998. The intermediate 1-(4-methylthiophenyl)–2-nitropropene was also found in a clandestine laboratory in the Netherlands in January 1997.In this study, reference standards were prepared and characterized. The ultraviolet, infrared and nuclear magnetic resonance spectral properties as well as the chromatographic and mass spectrometric (MS) data are reported.
