A mock jury study was conducted to test the hypothesis that perceptions of a witness can be biased by presumptuous cross-examination questions. A total of 105 subjects read a rape trial in which the cross-examiner asked a question that implied something negative about the reputation of either the victim or an expert. Within each condition, the question was met with either a denial, an admission, or an objection from the witness's attorney. Results indicated that although ratings of the victim's credibility were not affected by the presumptuous question, the expert's credibility was significantly diminished—even when the question had elicited a denial or a sustained objection. Conceptual and practical implications of these findings are discussed.This research was supported by funds provided to the first author by the Bronfman Science Center.  相似文献

Although studies on drug dealing have examined techniques sellers use to ensure against undercover infiltrations, none has explored the use of such techniques at the interactional level. The objective here is to address this void by exploring the perceptual shorthand dealers use to determine whether buyers in question are undercover. This perceptual shorthand processes one of two types of deception clues in making this judgment: trend discontinuity and interpersonal illegitimacy. Trend discontinuity is associated with police in formants and results from situations in which (I) familiar customers suddenly introduce unfamiliar others who wish to buy drugs and (2) familiar customers suddenly and signifcantly increase quantities they themselves desire to purchase. Interpersonal illegitimacy is associated with undercover agents and results from situations in which unfamiliar buyers emit certain physical and verbal “vibes” believed to be indicative of covert law en forcement personnel. Discussion focuses on the data's presuppositional and microstructural implications for restrictive deterrence (Gibbs, 1975). Data were drawn from semi-structured interviews with 32 semi-institutionalized heroin user-dealers located in a very large western US. city.  相似文献

Recent scholarship raises two questions about the historical relationship between gender and official responses to criminality. First, to what extent has the formal social control of women changed in the past two centuries? Second, to what extent can changes in the presence of women within the criminal justice system be traced to the same factors that account for the changing presence of men? To address these questions, I focus on women incarcerated for felonies in a southern state (Georgia) between 1870 and 1940. Along with a comparable sample of male offenders, this population forms the basis of a time-series analysis that compares, and seeks to account for, trends in admission rates. The analysis yields little evidence that women disappeared from formal system of punishment. Instead, there were gender similarities in punishment trends and in explanations for those trends. Concluding the paper is a discussion of its implications for further research on gender differences in punishment.  相似文献

This study used data from 299 police officers from 12 municipal police departments across the state of Virginia to determine the relationship between education and police performance. Performance was measured by supervisor evaluations of each officer's overall performance, communication skills, public relations skills, report writing skills, response to new training, decision making ability, and commitment to the police department. Significant correlations were found between education and most measures of performance. Most importantly, the results show a significant correlation between overall performance and education (r=24, p.<001). The only variables not proving to be significantly related to education were objective measures of the volume of arrests, number of times the officer required discipline, and number of accidents. Interestingly, the benefits of a college education do not become apparent until police officers gain experience. In addition, police, officers with only a high school diploma decreased in overall performance after five years of experience.  相似文献

The fingernail ridge patterns of a pair of identical twins were compared to each other, their parents, and an unrelated subject. The patterns of the twins' nails showed regions of strong similarity but were distinguishable from one another. Fewer similarities were found when comparing the nails to those of the parents and the unrelated control. The twins were shown to be monozygotic by means of DNA profiling. This therefore represents the first demonstration of unique fingernail ridge patterns in subjects shown conclusively to be identical twins. When the fingernail ridge patterns were examined with a scanning electron microscope, the backscattered electron (BEI) images were found to have superior contrast when compared to the secondary electron (SEI) images.  相似文献

This article explores theoretical and empirical issues in the application of clinical neuropsychological evidence to forensic issues in the criminal law. The nature of forensic neuropsychological evaluations is discussed with reference to issues of competency to stand trial, criminal responsibility, and other competencies in the criminal process. Examples of specific disorders relevant to criminal law standards are presented, together with data estimating the prevalence of brain dysfunction in criminal and forensic populations. Research is also reviewed on the role of neuropsychological brain dysfunction in the etiology of violence and criminally relevant behavior. Finally, empirical and ethical issues concerning the applicability and admissibility of forensic neuropsychological data in the criminal context are discussed.  相似文献

Using merged administrative data from welfare reform evaluations in three states, we estimate the effects of child care subsidy use on the length of time it takes for a welfare applicant to move into substantial employment. Findings show that the use of a child care subsidy during an unemployed or marginally employed spell of welfare receipt is associated with between a 0.6 and 1.7 quarter (or 11% to 34%) reduction in the time to substantial employment in two of the three state samples. The positive influence of subsidy use on transitions to substantial employment is strongest for those welfare applicants with the lowest earnings who are mixing welfare and work prior to subsidy receipt.  相似文献
