The study reports on a meta-analysis of attempts to correct misinformation (k?=?65). Results indicate that corrective messages have a moderate influence on belief in misinformation (r?=?.35); however, it is more difficult to correct for misinformation in the context of politics (r?=?.15) and marketing (r?=?.18) than health (r?=?.27). Correction of real-world misinformation is more challenging (r?=?.14), as opposed to constructed misinformation (r?=?.48). Rebuttals (r?=?.38) are more effective than forewarnings (r?=?.16), and appeals to coherence (r?=?.55) outperform fact-checking (r?=?.25), and appeals to credibility (r?=?.14). 相似文献

Limited attention has been given to the medium of story presentation in this process of narrative persuasion. The present study (N = 243) fills this gap by directly comparing narrative involvement across print and audiovisual versions of the same cervical cancer-related story. The mediation analysis revealed that exposure to an audiovisual narrative was associated with higher levels of cognitive and emotional involvement than exposure to the exact same narrative in its printed form. Yet the higher levels of transportation in the audiovisual condition came at a price of enhancing psychological reactance, eliminating the relative advantage of the film narrative. 相似文献

The present study conducted on twenty-five uncomplicated cases of acute myocardial infarction diagnosed by clinical and electrocardiographic
findings indicated significantly increased level of cardiac Troponin-T and increased activities of the enzymes total creatine
kinase, creatine kinase-MB, aspartate transaminase and lactate dehydrogenase as compared to the twenty-five healthy control
subjects. The level of cardiac Troponin-T and the activities of the enzymes total creatine kinase, creatine kinase-MB, aspartate
transaminase and lactate dehydrogenase was found to be higher in “Q” wave myocardial infarction patients as compared to the
non-“Q” wave and the controls. Since cardiac Troponin-T has been shown to increase in unstable angina and renal failure without
cardiac disease and creatine kinase-MB activity has been found to be normal in patients with unstable angina and increase
very slightly in patients with renal failure, it was concluded that a combination of cardiac Troponin-T and creatine kinase-MB
activity was sufficient for the early diagnosis of acute myocardial infarction. 相似文献

This article examines a decade of federal support for biotechnology in the Federal Republic of Germany in order to determine the impact of liberal corporatist patterns of decision-making on industrial policy. For this purpose, industrial policy is taken to include both public initiatives aimed at promoting the new technology and those designed to control its risks.Two distinct forms of corporatism are discernible in this case study. In the first, the principal actors are large businesses, the state, and to a lesser extent, the academic reserch community. These actors have been most influential in defining the scope and specific objectives of the federally funced R&D program in biotechnology. A more traditional form of corporatism, including organized labor, has been engaged in the debate on regulatory policies.In the case of biotechnology, these patterns of corporatism have created the consensus necessary for the adoption of a comprehensive R&D program, but have perpetuated certain barriers to technological innovation. In particular, the reliance on established peak organizations to formulate policy has discouraged structural changes that could have enhanced Germany's early competitiveness in biotechnology. Incrementalism has produced more favorable results in the context of regulatory policy, by permitting control strategies to develop in step with technological progress. 相似文献

ABSTRACT This paper examines the effect of the Education (Scotland) Act, 1981, in terms of one of its aims, that is, to increase parental control over assessment, recording and placement of children with special educational needs. Kirp (1982) has argued that British provision for children with special educational needs reflects a social welfare model based on a belief in professional benevolence and expertise. This is in contrast with the United States, where a human rights model of social welfare prevails. Kirp's account is critically examined through an analysis of the legislation and guidance literature, and also data gathered from interviews with professionals and parents. It is concluded that data do exist to support Kirp's argument. The legislation did not radically increase parents’ rights, and professionals themselves retained control through failing to provide parents with adequate information, often excluding them from multi‐disciplinary meetings and omitting to foster the involvement of voluntary organisations and Named Persons. 相似文献

This article examines the way in which some of the most discriminated against, disadvantaged and marginalised groups on the African continent, are re-defining education through strategies aimed at recognition of rights and social justice. It uses Fraser's analysis of social justice – distribution, recognition and participation – to examine the demands of the indigenous movement in Africa for rights to education. Over the past 10 years the concept of ‘indigenous’ has become embedded in African regional resolutions and reports while communities self-identifying as indigenous have been shaping new political and educational spaces for their participation and decision making about their development and their education. Taking the example of the East African pastoralists and the Maasai of Ngorongoro District in Tanzania, it looks at indigenous communities’ initiatives to define and achieve a qualitative education which is relevant and meaningful for their lives today. It concludes with a discussion of the potential for the indigenous movement in Africa to ‘reframe’ education for the benefit of not only indigenous communities but for all learners. 相似文献

本文考察了英国教育技术互用性标准中心(CETIS)通过支持国家项目(即英国联合信息系统委员会(JISC)和高等教育委员会的英国开放教育资源试点项目,详见http://www.jisc.ae.uk/oer),以促进发布开放教育资源方面的经验,并探索了如何让我们的支持模式对其他相关项目有所启发,并能改编用于鼓励开放课件运动的可持续性技术支持网络。作为一个涵盖英国众多大学的国家层面的创新举措,众多开放教育资源提供者参与了英国开放教育资源(UKOER),这包括个别教育者、学科联合体和机构。考虑到这种多样性,从一开始我们就意识到没有任何一种技术解决方案能适合所有的项目。因此,也没有委托专门的工具、描述性标准、交流或分发机制(除要求所有制作的资源应该放在国家学习资源库中外,详见http://jorum.ae.uk)。为了支持这一项目,我们引导采取不同的方法和形成不同的社群,也许在支持发布开放教育资源方面,任何类似的跨机构创新都将会面临相似的问题。我们的项目支持方法已从具体的细节问题发展到提供基本的支持原则,从而预测其他问题,并推动最佳实践。我们的做法是:通过会议上的技术汇报和讨论机会,以及在博客上发帖,激发讨论;通过技术评论讨论,并记录针对这些公布在网上的讨论的总结性内容,从而调查个别项目的技术选择;针对通过以上方式所发现的问题,以及项目博客上凸显的问题,做出相应的反馈。考虑到如何使这一方法在更广泛的范围内应用,我们也反思了这种公开的工作模式所面临的挑战、这一方法的开支、适应性,以及我们所认为的其在支持开放教育资源管理和传播方面所扮演的角色。 相似文献

Selective attention in processing of visual information by pigeons, trained on alternating sessions with two colors (red and
green) and two forms (a diamond and an X shape) differentially associated with a left—right key choice task, was examined.
A color and a form were presented together on probe trials during sessions in which, on other trials, only one of the dimensions,
color or form, was shown. The dimension in effect on the surrounding trials had no influence on choice when the information
provided by the two dimensions on probe trials was in conflict—color correct for one choice and form for the other. When both
color and form redundantly cued the correct choice, there was no increase in accuracy in comparison with that associated with
one dimension. Following separate training on the color and form discriminations, pigeons appeared to base their choices on
color on some trials, on form on other trials, but not on both simultaneously. These findings are discussed in terms of an
exemplar model of information processing. 相似文献
