文章考察了不同类型的投资者(机构、个人)在上市公司募集资金投向变更公告前后的交易特征和行为。结果发现:公司募资投向变更市场反应为负,变更事件显著导致公司未来业绩变差,这说明变更对于绩效的影响是无效率的;机构投资者表现出了显著的信息优势,整体上,机构(及共同基金)的交易行为在更大程度上体现为价值性投资;个人投资者只为机构投资者提供了流动性。研究结果具有明晰的政策含义,即监管机构在严格管控资金用途变更的同时,既要发展机构投资者,又要提升个人投资者教育。  相似文献

This study presents evidence on the cross-cultural generalizability of differential association/social learning theory by testing whether the causal processes of learning attitudes toward deviance, posited by the theory, are equally applicable, and the causal links, specified by the theory, are equally strong in two diverse cultures—the USA and Japan. Drawing on the literature concerning cultural variability in individualism-collectivism, we predicted that the effects of peer reactions to deviance and peer deviance on a person’s attitudes toward deviance should be stronger in Japan than in the USA, and that the mediating effect of a person’s attitudes on the relationship of peer reactions and peer deviance to a person’s deviance should be weaker among Japanese than among Americans. Analyses of comparable survey data from college students in the USA (N?=?625) and Japan (N?=?591) provide generally supportive, but somewhat mixed, evidence regarding our predictions. In both countries, peer reactions to deviance predicted student attitudes toward deviance more strongly than did peer deviance. Peer deviance strongly predicted student deviance, while peer reactions to deviance predicted less strongly, and the effects were mediated by student attitudes in both countries. Contrary to the hypotheses, peer reactions and peer deviance did not predict student attitudes more strongly in Japan than in the USA. Also, peer deviance predicted student deviance more strongly in the USA than in Japan. In agreement with the expectations, the relation between student attitudes and student deviance was stronger in the USA than in Japan.

Sudden death due to massive hemoptysis during management of tuberculosis occurs in a considerable number of patients. However, when massive airway hemorrhage occurs in a patient in whom tuberculosis has not been confirmed and a blood is not apparent externally on the face/body, it is difficult to immediately identify the cause of death as airway obstruction by tuberculous bleeding in the airway. We encountered an 83‐year‐old Japanese woman with her medical history included treatment of tuberculosis in her 20s who was in cardiopulmonary arrest on arrival (CPAOA), and the cause of sudden death could not initially be identified. Postmortem CT (PMCT) and autopsy revealed that the cause of sudden death was airway obstruction/asphyxia by tuberculous massive airway hemorrhage. Identification of the cause of death facilitated a subsequent active contact investigation and led to prevention of secondary tuberculosis infection.  相似文献

二十世纪以来,法律发展的新趋势是私法的公法化与公法的私法化。随着社会的变迁,人权的凸显,刑法的公法性质也受到了意思自治理念的渗透。刑事和解制度就是这一进程的结果之一。  相似文献

We examined the usefulness of the dura mater in identifying human remains. Dura mater was collected from 50 cadavers, including drowned, charred, and mummified remains. The STR genotype using the AmpFlSTR Identifiler Kit could be typed at 15 STR and amelogenin loci in 30 samples of 33 cases. Furthermore, the ABO genotype and amelogenin using gel-based methods could be typed in 44 samples of 50 cases. In cases with successful typing of STR, ABO-DNA, and amelogenin, the longest time after death was from 12 to 26 days in a drowned body. The minimum quantity of dura mater required for DNA extraction was about 2.5 mg, dried and fixed by ethanol, in a cadaver 15 h after death. The state of the DNA from the dura mater from the calvaria may be better than that from the basis cranii interna. We found that DNA from dura mater is one of the most useful samples for forensic identification.  相似文献

秘密侦查概念辨析   总被引:1,自引:0,他引:1  
作为一项特殊的侦查手段,秘密侦查在打击犯罪方面发挥着重要的作用。然而在对秘密侦查的认识上,理论界有不少混乱之处,这就需要为秘密侦查的认定重新划定标准,从内容和形式相统一的角度,赋予秘密侦查新的含义。  相似文献

作为一个部门法,"环境法"比传统的"环境保护法"称谓更科学;"环境法"应以"人类利益"为中心,"生态利益中心论"不妥当;环境法调整环境保护关系,而不是调整所有"与环境有关的人类行为";环境法通过调整人与人的行为关系协调人与自然的关系,而不直接调整人与自然的关系.  相似文献
