In our study newborn infants were presented with lists of lexical and grammatical words prepared from natural maternal speech. The results show that newborns are able to categorically discriminate these sets of words based on a constellation of perceptual cues that distinguish them. This general ability to detect and categorically discriminate sets of words on the basis of multiple acoustic and phonological cues may provide a perceptual base that can help older infants bootstrap into the acquisition of grammatical categories and syntactic structure. 相似文献

医疗事故纠纷的本质及法律责任 总被引:2,自引:0,他引:2
施卫星 《医学与哲学(人文社会医学版)》1999,20(5):1-4
医疗事故纠纷及处理的道德本质和司法原则在于对病人权利的维护。强化医务人员对病人生命与健康的医德责任感和病人权利意识,并使之成为自律、自觉的行为是预防和减少医疗事故纠纷发生的第一要素;而提高医务人员的法律意识,完善法律的制约机制,对医疗事故的防范是同样重要的。 相似文献

Everyone knows what attention is. It is the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought. Focalization, concentration, of consciousness are of its essence. It implies withdrawal from some things in order to deal effectively with others. William James Principles of Psychology 相似文献

老年人群房颤发病率高,缺血性脑卒中风险大,又是抗凝治疗导致出血的高危人群,因此要大胆地选择华法林抗凝治疗,并小心地严密监测INR值(1.6~2.5),严格控制其他出血危险因素.老年房颤心律失常的治疗重在个体化,重在改善症状,首选控制心室率;发作时血流动力学不稳定且药物不能满意地控制心室率时才选择复律治疗;症状明显而药物疗效欠佳患者可选择导管消融治疗. 相似文献

厘清医师说明义务的内涵、性质能够使患者和医师明晰自己的权利和义务,有利于保护患者知情同意权.对于医师说明义务的法律性质,有主张医师的说明系患者有效同意之逻辑前提的“承诺无效说”;也有“医疗合同上的附随义务”的观点;还有认为其应是一项法定的注意义务.在对这些观点进行评析后提出此义务应是一项法定的合同义务. 相似文献

Together with the completion of the Human Genome Project, biomedical research has marched into the "Post-Genomic Era." In order to take advantage of this extracted gene related information extensively and precisely so as to realize man's biological phenomena as well as the mechanism of pathogenesis, consequentially, a large scale sample collection of different geological areas and/or ethnic groups becomes necessary for the future population based genetic research of a country and, in turn, the construction of population-based genetic database (Biobank). In recent years, both mainland China and Taiwan have not only made great progress in information and computation technologies, but have also gradually taken a close look into the quality of medicine delivery. Thus, it becomes unavoidable for both sides to create each one's population-based genetic databases (Biobank). Theoretically speaking, the Biobank development shall benefit the study on the correlation between genes and disease and also the solution for disease treatment as well. At the same time, medical diagnostic technology has also been significantly improved. It is believable that the population-based genetic database might be utilized to promote medical quality and to reduce the cost of public health delivery. Further; in the near future, it might become the "raw materials "for medical research application. However when taking promotion of public welfare as the premises for a Biobank development, the severe and multi challenge occurred against the traditional legal rules in terms of the privacy protection, public trust development, the compliance of informed consent principle, the implementation of benefit-sharing doctrine and the possible discrimination concern about the population/participants selection and some other ELSI issues. In this paper, the major legal issues encountered by the Biobank development will first be reviewed accompanied by the background information concerning the Biobank development scenario crossing the Taiwan Strait. Also, mainly following the realm of comparative policy or legal approaches, the paper learning from the fruits of this comparative study, tries to propose some recommendations for future legislative consideration by both mainland China and Taiwan. It's been this author's wish that, when establishing a large scale population based Biobank, the promotion of public trust shall be placed as the primary goal together with the emphasis on supporting publicity and transparency on the administrative practices, so as to encourage the public participation in observing the principle of altruism and, in turn, benefit the future biomedicine development. 相似文献
