This article reviews the December 2007 United Nations Climate Change Conference in Bali. It considers expectations for the meeting and whether the event delivered on these expectations. It also evaluates the long-term context of the meeting and examines the discussions in Bali on the post-2012 period (when the Kyoto Protocol's first 'commitment period' expires). The article finds that the Bali meeting did not necessarily meet public expectations or respond directly to the latest scientific assessments calling for urgent action. However, the article also finds that Bali was successful in the context of the prevailing political and diplomatic realities and the immense complexity of the climate change challenge – a problem that does not lend itself to a 'quick fix' solution. The article concludes that Bali produced a solid outcome that gives direction to future talks and sets a clear deadline for their completion. Finally, it argues that, contrary to some experts' opinion, the lack of detail in the Bali outcome may prove to be a strength rather than a weakness, since it provides flexibility to negotiators as they try to craft a consensus by the end of 2009. 相似文献

The comparison of consecutively manufactured tools and firearms has provided much, but not all, of the basis for the profession of firearm and toolmark examination. The authors accept the fundamental soundness of this approach but appeal to the experimental community to close two minor gaps in the experimental procedure. We suggest that “blinding” and attention to appropriateness of other experimental conditions that would consolidate the foundations of our profession. We do not suggest that previous work is unsound. 相似文献

We examined whether eyewitness identification latencies for sequential line‐up decisions indicate an optimum time boundary that reliably discriminates accurate from inaccurate decisions. Participants (N = 381) observed a crime simulation and attempted two separate identifications from target‐present or target‐absent sequential line‐ups. As has previously been found with simultaneous line‐ups, the optimum time boundary identified did not reliably discriminate accurate from inaccurate identifications for both line‐up targets. Diagnosticity for choosers was, however, much higher at very high confidence levels than at lower levels. Possible reasons for why one index of signal strength (confidence), but not another (latency), might postdict accuracy within the sequential framework were presented. 相似文献

The article concentrates on the police role in the investigative stage in various criminal justice systems and the relationship with each national prosecution service. It is shown that in this respect the police function varies significantly from country to country. According to its legal competencies and factual procedural possibilities, the article will give a short overview of the national differences but also show that similar mechanisms are developed. 相似文献

The purpose of this article is to examine the self-reported sexual attitudes and behaviors of adolescents living in the Midwest. A survey was administered to 463 African American youths ages 11–19. The results indicate that intent to have sexual intercourse, reported likelihood toward having sexual intercourse, and whether participants felt that they would have sex in the next 3 months were predictors of whether they had sexual intercourse at the 3-month follow-up. The results also revealed that the opinions of referent others did not predict sexual intercourse at 3 months. Negative attitudes toward condoms did predict condom use at 3 months and the opinions of referent others also predicted condom use at 3 months. Limitations as well as future research are also discussed. 相似文献
