Educating Jurors about Forensic Evidence: Using an Expert Witness and Judicial Instructions to Mitigate the Impact of Invalid Forensic Science Testimony 下载免费PDF全文
Invalid expert witness testimony that overstated the precision and accuracy of forensic science procedures has been highlighted as a common factor in many wrongful conviction cases. This study assessed the ability of an opposing expert witness and judicial instructions to mitigate the impact of invalid forensic science testimony. Participants (N = 155) acted as mock jurors in a sexual assault trial that contained both invalid forensic testimony regarding hair comparison evidence, and countering testimony from either a defense expert witness or judicial instructions. Results showed that the defense expert witness was successful in educating jurors regarding limitations in the initial expert's conclusions, leading to a greater number of not-guilty verdicts. The judicial instructions were shown to have no impact on verdict decisions. These findings suggest that providing opposing expert witnesses may be an effective safeguard against invalid forensic testimony in criminal trials. 相似文献

Using an integration of social control theory and the routine activity perspective, adolescent time use was examined for effects
on problem behaviors. We examined a wide variety of time use categories, including homework, extracurricular activities, sports
time, alone time, paid work, housework, television watching, as well as indices of family time and peer time, for their effects
on heavy alcohol use, cigarette smoking, illicit drug use, delinquency and sexual activity. The study employed a representative
household sample of adolescents (n=606) and took into account important sociodemographic factors – gender, age, race (Black and White), and socioeconomic status.
The most important predictors of adolescent problem behaviors were family time and peer time. Family time serves as a protective
factor against all five problem behaviors while peer time is a highly significant risk factor for all five problem behaviors.

The issue of social networks is central to scholars' examinations of China's economic reform and its transitional society. This article presents an effort to examine the impact of the property rights reform on the evolution of entrepreneurs' social networks in the context of rural China. This study proposes three different patterns of social networks: in-group networks, official-centered networks, and market-oriented networks; and examines how the significance of different network patterns has evolved under the context of institutional change. By using data collected in Wuxi city, Jiangsu province, China, this article attempts to explore four significant questions. Do social networks still matter? How is the significance of different patterns of social networks changing? Why could this happen? In which fields do social networks still matter? 相似文献
