Two studies were conducted to investigate the effects of impeachment evidence in civil cases. According to the Federal Rules of Evidence, impeachment evidence can be used to judge defendant credibility, but not to infer bad character or harmful propensity. Jury-eligible subjects watched a realistic videotaped trial in which prior convictions for perjury and character evidence of honesty or dishonesty were manipulated. In Study 1, subjects provided individual judgments, and in Study 2, subjects engaged in group deliberations. Impeachment evidence did not strongly affect verdicts, and character evidence of honesty decreased liability only when limiting instructions were given. In both studies, however, the evidence produced legally permissible and impermissible inferences. Prior convictions reduced perceived credibility and increased inferences of negligent propensity. Evidence of dishonesty produced lower credibility ratings and negative character impressions. Credibility, character, and propensity assessments were all important in the verdict-reaching process, suggesting that juror's decisions do not conform to the requirements of the Rules of Evidence.This research was supported by National Science Foundation under grant no.

We would like to thank Richard Lempert for his helpful comments on an earlier draft, and Jerry Busmeyer, Maureen Crowley, Myrna Gaidos, David Hullinger, Randy Larsen, Bill Little, Charles Nelson, Richard Schweickert, Harold Seymour, and Al Solomon for serving as witnesses in the trial videotapes. 相似文献

Postmortem cerebrospinal fluid pleocytosis 总被引:1,自引:0,他引:1

We show that postmortem cerebrospinal fluid (CSF) pleocytosis is a common event. Postmortem cerebrospinal or ventricular fluid was obtained from children and adults. The cells were counted and morphologically characterized using several histochemical markers. Infants exhibit a brisk postmortem CSF pleocytosis. Sudden infant death cases have relatively high CSF counts. Typeable cells are mononuclear and consist of approximately 60%-70% lymphocytes and 20%-40% macrophages. When postmortem duration is greater than 12 h, the cells become vacuolated and cannot be identified. The etiology of these findings requires further study. 相似文献

Recent research on incest suggests that it is a complex phenomenon which assumes a variety of forms in different situations. A tentative typology based on prior research and clinical reports is presented. A preliminary framework for recognizing and dealing with various types of incest is outlined and a discussion of intervention and prevention strategies is provided. 相似文献

Historically, in crimes involving heavy caliber rifles, only conventional factory‐made versions have been used. However, in recent years the number of homemade long‐barreled rifles is increasing. The characteristics of two such firearms that have been submitted to the Turkish Criminal Laboratory are discussed here. When the main parts of the guns were examined in detail, it was noted that nearly all of the parts had been made carelessly, with several structural defects visible. It was determined that the homemade heavy caliber rifles were unfit for efficient use and it was possible that they could have seriously harmed the shooter had they been fired. The development of these kinds of gun and the possibility of their use spreading throughout the country in terrorist attacks could cause a serious threat to national security. 相似文献

This paper analyzes a hidden cost of war: the effect of the mass mobilization of reserve troops on the response times of domestic emergency services to accidents. We provide a statistical examination of this linkage following the US invasion of Iraq in 2003 and find that mobilization significantly increases response times to accidents in the United States. These mobilization-related costs are exacerbated by both legal restrictions and issues of replacing highly specialized human capital. 相似文献
