Mock jurors were permitted to take notes during a trial simulation and to have those notes available during an individualized test of recall. Compared to non-notetakers, those who took notes showed superior recall and were more involved in the trial proceedings. The quantity of notes taken, their accuracy, and their organization all correlated positively with accuracy of recall. 相似文献

This study explores the associations of sexual revictimization (experiencing sexual abuse in childhood and adulthood) in a sample of 230 African American women who are low-income. Data indicate that women who experience sexual revictimization are more at risk for emotional stress and psychological pathology than women with no history of abuse. In addition, women who are revictimized appear to be at greater risk for emotional problems than women sexually abused only as a child or sexually assaulted only as adults. Revictimization also appears to be associated with an increased probability of engaging in prostitution, even higher than women with childhood- or adult-only victimization, who showed increased probability when compared to women never abused. Finally, women who are revictimized showed increased HIV risk, in that they were 4 times less likely than other women to consistently use condoms, but no more likely to be in monogamous relationships or less likely to have multiple partners. 相似文献

The case of seven urine samples collected for anti-doping purposes during a cycling stage race with moderately elevated testosterone and epitestosterone ratio (T/E) is reported. The very low probability of having all seven urine samples with such similar elevated T/E ratio (from 3.2 to 4.7) was very suspicious. Different pattern classification tools were tested to categorize the most similar steroid profiles, but none of the models enabled a clear classification of the different urine samples. Subsequently, genetic profiling of all urine samples was performed and demonstrated that three of the seven samples were collected from the same cyclist. Finally, the International Federation confirmed DNA profiling results. This suggests that urinary steroid data using several methodologies are not appropriate for identification purposes and to an extent not unique to individuals. 相似文献

Using data from a new household survey on environmental attitudes, behaviors, and policy preferences, we find that current weather conditions affect preferences for environmental regulation. Individuals who have recently experienced extreme weather (heat waves or droughts) are more likely to support laws to protect the environment. We find evidence that the channel through which weather conditions affect policy preference is via perceptions of the importance of the issue of global warming. Furthermore, environmentalists and individuals who consult more sources of news are less likely to have their attitudes toward global warming changed by current weather conditions. These findings suggest that communication and education emphasizing consequences of climate change salient to the individual's circumstances may be the most effective in changing attitudes of those least likely to support proenvironment policy. In addition, the timing of policy introduction could influence its success. 相似文献
