自苏联解体以来,世界的发展趋势逐渐变为一超多强的格局。美国作为世界上惟一的超级大国,其经济政治各方面的政策对本国及至全世界都会产生重要影响。而美国的两党制一直以来就是全美的核心政治问题。在2004年11月2日到3日的美国总统大选中,共和党候选人布什最终以286票对252票的微小优势战胜了民主党候选人克里,连任美国总统。我们依然在以大象和驴子玩跷跷板的游戏来概括美国的两党选举。至于美国的民主是否真实,选举的过程是否公平,投票的程序是否有暗箱操作的嫌疑,我们且不去关注。至于看似可爱的布什先生为何胜过看似仁慈的克里先生,各大媒体也有一些深切入理的看法。笔者现仅就美国大选过程中选民的心理作一些粗浅分析,以期对美国及选举制度有更清晰的认识。 相似文献

The author describes problems facing Armenia in reorganization of the structure of science in the post-socialist era with
the aim of utilizing limited state resources more efficiently by reducing the number of separate scientific institutes, concentrating
on essential core subjects required by the nation and encouraging all other projects to compete in the international arena
for grant sponsorship.
An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance
in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002. 相似文献

Atypical attention, while not a diagnostic feature, is common in individuals with autism spectrum disorders (ASD). The study of these atypicalities has recently gained in both quantity and quality, due in part to an increased focus on attentional atypicalities as one of the earliest signs of ASD in infancy. A range of attentional processes and components have been investigated, and the methods used are varied, from Posner-type paradigms, to the more recent use of eye-movement recording and change-detection techniques. This methodological complexity is one factor in the production of conflicting evidence on the topic of attention in ASD. This review uses a focus on methodology to clarify the literature to date and provide a resource for researchers wishing to study attention in ASD. Other factors that have contributed to the current discrepancies in findings are discussed, particularly the role of individual and group differences within the population of people with ASD. 相似文献

Observers viewed visual stimuli in which one object moved to a position of partial occlusion by another. The objects were presented as two-dimensional profiles moving in an undefined space, so the partial occlusion supports several different physical interpretations. In fact some stimuli reliably gave rise to a perceptual impression that the moving object penetrated or pierced the stationary one. This kind of interaction impression has not previously been reported. The impression was maximized by rapid deceleration to a halt with minimal occlusion. If the object decelerated more slowly, so that it was completely occluded or projected from the far side of the stationary object, it was perceived as moving behind the stationary object. The shape of the moving object and its speed prior to occlusion had significant but small effects. 相似文献

A refined analysis of the peck order in chickens was offered as a test of the notion that for this species, different responses such as leaping and various types of pecking need not be interchangeable indexes of aggression. Indeed, tests showed that particular response types of the birds were differentially mediated by organismic or environmental factors. In large cages pecking at the body was most frequent by birds that had a home-cage advantage. Contrarily, rates of aggressive leaping were independent of this environmental influence, with males having an advantage over females. Males showed more head pecking than females, but the profile for this sex difference did not resemble the profile for leaping. Correlational analyses revealed that whereas head pecking between testmates was not matched in frequency, leaping was positively related. Finally, the behavior of birds tested in small cages differed from that of the large-cage subjects. Although there was more head pecking in the small cages, males did not have an edge, and leaping was infrequent. Such results indicate that these responses cannot be viewed as interchangeable indicators of aggression in fowl. 相似文献
