有时间压力下学习率对学习时间分配议程的影响:来自眼动的证据

利用眼动分析技术,通过设置不同难度和分值的计算项目,探讨了在有时间压力下学习者的学习时间分配。结果发现:(1)在首次项目选择上,学习者优先选择学习率最高的项目;(2)在学习过程中,学习者的项目选择次序也是根据学习率由高到低。总之,在学习时间分配上,如果需要权衡难度与分值,学习者会考虑单位时间的获益,也就是以学习率为议程的主要依据。研究不仅利用眼动分析技术证实了基于议程的学习时间分配模型,而且进一步揭示了学习率是设置学习时间分配议程的重要依据。     

The Imperatives of Narrative: Health Interest Groups and Morality in Network News

This article examines some of the story conventions of network television news to explain the ways in which healthcare interest groups develop and maintain their presence in this medium—a process that has significant implications for public understanding of healthcare issues, and therefore to bioethics. The article is divided into three sections. The first section focuses on three major normative conventions of television news: adherence to a simple narrative structure, the balance ethic, and avoidance of the “think-piece” and outlines the basic strategies available to interest groups for exploiting these normative conventions. Section two introduces three case studies of organizations and individuals who have run high-profile media campaigns. Section three explores the implications for bioethics of the observations made in this article.     

Challenges in studying the effects of scientific societies on research integrity

Beyond impressionistic observations, little is known about the role and influence of scientific societies on research conduct. Acknowledging that the influence of scientific societies is not easily disentangled from other factors that shape norms and practices, this article addresses how best to study the promotion of research integrity generally as well as the role and impact of scientific societies as part of that process. In setting forth the parameters of a research agenda, the article addresses four issues: (1) how to conceptualize research on scientific societies and research integrity; (2) challenges and complexities in undertaking basic research; (3) strategies for undertaking basic research that is attentive to individual, situational, organizational, and environmental levels of analysis; and (4) the need for evaluation research as integral to programmatic change and to assessment of the impact of activities by scientific societies. This topic was initially discussed at the AAAS-Office of Research Integrity (ORI) meeting in Washington DC on the theme: “The Role and Activities of Scientific Societies in Promoting Research Integrity” held on April 10–11, 2000. Joyce Miller Iutcovich, PhD, is President of the Keystone University Research Corporation.     

Ciencia,comunicación y mercado: la condición mediática de la ciencia

Resumen

Se realiza en este artículo una introducción a los problemas de la comunicación científica desde la perspectiva de la comunicación de masas en un mercado del conocimiento, considerando tanto los aspectos constructivos de la perspectiva del mercado cultural como, asimismo, los aspectos distorsionantes y sesgos que se producen. En ambos casos se realiza una transposición al campo de la comunicación científica de algunos de aquellos problemas y procesos más relevantes que ya han sido caracterizados para la comunicación de masas y del modo en que las mediaciones condicionan la difusión científica. Por último se hace una reflexión sobre estos problemas en el escenario de la ciencia en español en su encuentro con la mundialización de la ciencia en un espacio representational lingüística y tecnológicamente unificado.     

Blindsided? September 11 and the Origins of Strategic Surprise

The devastating terror attacks of 11 September 2001 have often been characterized as a "bolt from the blue." Drawing inspiration from the political psychological literature on strategic surprise, this article poses the deceptively simple question of why so many U.S. policymakers were caught so woefully off guard last year. Through a preliminary empirical exploration of three broad explanatory "cuts" derived from the relevant interdisciplinary literature—psychological, bureau–organizational, and agenda–political—the authors seek to shed light on the sources of failure that may have contributed to 9/11 and point to promising avenues of investigation for future research as the available empirical record becomes more complete.     

Investigating ethical issues in engineering design

This paper aims at contributing to a research agenda in engineering ethics by exploring the ethical aspects of engineering design processes. A number of ethically relevant topics with respect to design processes are identified. These topics could be a subject for further research in the field of engineering ethics. In addition, it is argued that the way design processes are now organised and should be organised from a normative point of view is an important topic for research. An earlier version of this paper was presented at the International Symposium on Technology and Society 2000, Rome, 8 September 2000.     

马普人类发展研究所毕生发展心理研究中心：研究主题和研究活动展示

Paul B. Baltes于1981年在马普人类发展研究所成立的毕生发展心理研究中心已经使毕生发展心理学成为了发展心理学中的一个重要的概念分支。2004年以来,中心已经将研究项目扩展到了发展行为神经科学。中心主要在三个主题上开展研究工作: (1) 研究作为成熟、学习和衰老的交互作用的结果, 毕生的不同发展阶段中人类行为变化的规律: (2) 发展能够整合来自于自身机能、时间序列、以及行为和神经层面分析等领域实证证据的理论和方法体系。(3) 通过探索不同年龄可塑性上的差异寻找发展的机制。中心继续重点关注成人晚期和老年期, 这为理论和实践上的创新提供了独特的机遇。同时, 中心加强了对包括婴儿期和儿童早期在内的个体发展早期阶段的研究。本文报告了来自四项从行为和神经层面分析感觉和认知发展的研究的最新发现。
