The mammalian hippocampus is certainly one of the best investigated brain regions. It fascinates neuroscientists particularly because of its important role in memory. The names for the various parts of the hippocampal formation were created in the course of the first thorough explorations of human brain anatomy. The present, internationally agreed terminology reflects an unfortunate muddle that has been going on for several hundred years. Not surprisingly, even today the origins of some of the names are not always given correctly. It is generally accepted that the Italian anatomist Arantius was the first to apply the term 'hippocampus' to part of that region in the human brain. To later authors, however, this name appeared more or less enigmatic and they proposed various other terms. Yet careful reading of the entire original text of Arantius leads to the conclusion that it was not the hippocampus in our modern terms but the dentate gyrus which he compared to a little sea horse or a silkworm. 相似文献

This paper presents a model of the determinants and consequences of computer efficacy with particular attention devoted to the mediating processes through which users form efficacy judgements, including their analysis of task requirements, assessments of situational and personal resources/constraints, and attributional analysis of experience. Of particular interest to this paper are the attributional processes affecting computer efficacy. Recommendations for computer and attributional training are advanced. 相似文献

正The symptoms of anxiety and depression are highly overlapping with each other and are hard to differentiate in clinical settings.Researchers have attempted to develop measures specifically capturing and differentiating symptoms of these two constructs.The Depression Anxiety Stress Scale(DASS)was developed to meet this challenge and has been shown to capture depression,anxiety,and stress 相似文献

互联网背景下的平台经济时代重构了人与组织之间的关系,需要创新性地建立一种基于平台隐喻的领导范式和实践途径。本文在文献内容分析基础上对6位管理学领域专家和21位企业管理者进行结构化访谈,经过质性研究过程归纳38个题项,进行606份有效问卷的实证分析并通过信度和效度检验,开发出平台型领导量表的22个测量题项以及分享利他、交互协作、孵化创客、度己化人、赋能平等5个构成维度,并给出五个构成维度的内涵释义。该研究较为完备地刻画了平台型领导的行为特征,弥补了平台型领导研究缺乏测量量表和维度界定的理论缺口,所确定的5维度22题项具有系统性、涵盖性和内在区别性,具与有互联网、大数据背景下企业平台化经营和平台化升级的契合性,为践行平台型领导提供了理论依据和行为导向,对推动平台领导力的进一步研究具有积极作用。 相似文献

Electronic Commerce: Definition, Theory, and Context 总被引：8，自引：0，他引：8
Rolf T. Wigand 《The Information Society》1997,13(1):1-16
Electronic commerce is a relatively new concept that crept into the business vocabulary during the 1970s. A picture of electronic commerce is emerging in which the Internet will become the essential dial-tone for conducting business by the year 2000. This contribution addresses definitional, theoretical and contextual issues including the nature, drivers, enablers, and the magnitude of electronic commerce. The author discusses the role of electronic markets, the effects of information technology on electronic commerce, interactivity, and the evolution of disintermediation to reintermediation. A definition and typology of electronic commerce are offered. Theoretical and conceptual approaches to electronic commerce are advanced in terms of (1) transaction cost theory, (2) marketing, (3) diffusion, (4) information retrieval, and (5) strategic networking. Lastly, the author poses the question of how electronic commerce adds value. 相似文献
