Previous studies have shown that the emotional behavior displayed during testimony may affect the perceived credibility of the witness. The present study compares credibility ratings by Norwegian court judges with those made by lay people. The participants viewed one of three video-recorded versions of a rape victim's statement, role played by a professional actress. The statement was given in a free-recall manner with one of three kinds of emotions displayed, termed congruent, neutral, and incongruent emotional expression. The results show that, in contrast to lay people, the credibility ratings of court judges and their votes for a guilty verdict were not influenced by the emotions displayed by the witness. Results are discussed in terms of professional expertise. 相似文献

Chemical profiling of heroin recovered from the North Korean merchant vessel Pong Su 总被引:5,自引:0,他引:5

Heroin samples, seized from the North Korean merchant vessel Pong Su in Australian waters, were analyzed to determine geographic origin. Duplicate samples were analyzed by the National Measurement Institute's Australian Forensic Drug Laboratory and the United States Drug Enforcement Administration's Special Testing and Research Laboratory. Alkaloid ratios were determined by both liquid chromatography-diode array detection (LC-DAD) and capillary electrophoresis-diode array detection (CE-DAD) techniques. Acid/neutral manufacturing by-products were determined by solvent extraction followed by gas chromatography-mass spectrometry (GC-MS). Solvents, trapped in the heroin particles during manufacture, were detected by both static headspace GC-MS and purge and trap GC-MS. The alkaloid ratios obtained were consistent with heroin of a Southeast Asian (SEA) origin and principal component analysis of the alkaloid results demonstrated the presence of at least four subgroupings within the seizure. The solvent analysis detected diethyl ether and ethyl acetate, solvents typically seen in SEA heroin. However, the acid/neutral analysis revealed compounds not normally seen in heroin of a SEA origin. Furthermore, sterol-like molecules, always detected in the acid/neutral analysis of SEA heroin, were absent from the Pong Su samples. The Pong Su heroin, although similar to SEA heroin, has sufficient differences to classify it as having an unknown origin at the time of this writing. 相似文献

The United States–India relationship was fraught with misapprehension and ideological disagreement during the 1950s. Public diplomacy provides a valuable context for examining these dynamics. This analysis assesses the planning, deployment, and reception of American public diplomacy to India under President Dwight Eisenhower, a period encompassing Washington’s 1954 alliance with Pakistan and economic aid to India in 1957–1958. Public diplomacy reflects the Administration’s difficulty in clarifying its interests in India. The rhetorical and moralising approach of India’s leadership, and their prominence in the global non-aligned movement, contributed greatly to this ambivalence. Public diplomacy planning highlights Washington’s difficulties in confronting India’s identity in world politics; it struggled to craft messages on racial attitudes, consumerism, and Communism, whilst Soviet public diplomacy gave strong competition throughout the period. At the same time, several aspects of American public diplomacy resonated with Indian audiences, indicating that there was the possibility of a closer American relationship with India had Washington taken a different high policy approach to the region. 相似文献

The climate change problem, or global warming, has gained a prominent place on the international political agenda, since the mid-1980s, when it first attracted political attention. The problem was initially perceived mainly as an environmental problem that could be resolved by technological solutions, its current perception, this essay argues, is best characterized as that of an enviro-economic problem. A perception that is exemplified by the ongoing negotiations for the development of economic mechanisms to tackle the problem. The climate change arena is a complex one, involving dichotomies between developed and developing countries, between fossil fuel producing and importing countries and between small island developing states and other states. This essay outlines the interests that play a role in the climate change negotiations and discusses the international climate change regime as contained in the United Nations Framework Convention on Climate Change and its Kyoto Protocol. It concludes that the climate change negotiations are complicated by the fact that the negotiators, in addition to developing new substantive rules for a complex problem, are involved in developing new systemic rules for the international legal system. These new systemic rules have more in common with rules of national systems of public or administrative law than with traditional rules of international law, which have many similarities with national systems of contract law. 相似文献
