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

There is increasing divergence in the academic outcomes of African American males and females. By most accounts, males are falling behind their female peers educationally as African American females are graduating from high schools at higher rates and are going on to college and graduate school in greater numbers. Some have suggested that school completion and performance is associated with how students feel about themselves. The purpose of this study was to explore gender differences in the relationship between self-perceptions and 2 academic outcomes among a sample of 243 African American high school sophomores. The results suggest that, overall, females are more favorably oriented toward high school completion. Both male and female students with more positive self-perceptions have stronger intentions to complete the current year of high school. Higher grade point averages were more strongly associated with greater self-efficacy for females than for males. Given these findings, increased attention to educational programming, societal messages, and future research is warranted. 相似文献

Towards a Guide for Constructing and Disseminating Counternarratives to Reduce Support for Terrorism
Despite widespread recognition that the use of counternarratives is an important strategic component of countering violent extremism, to date, there are no comprehensive guidelines on how to develop and distribute counternarratives to effectively reduce support for terrorism. To redress this, we offer communication and psychology theory-based procedures for (1) analyzing terrorist narratives, (2) constructing counternarratives that challenge terrorist narratives, and (3) disseminating the counternarratives to overcome barriers to persuasion. Analysts and practitioners can use such guidelines in developing counternarratives to reduce support for violent extremism. 相似文献

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs. 相似文献
