The paper surveys the currently available axiomatizations of common belief (CB) and common knowledge (CK) by means of modal propositional logics. (Throughout, knowledge — whether individual or common — is defined as true belief.) Section 1 introduces the formal method of axiomatization followed by epistemic logicians, especially the syntax-semantics distinction, and the notion of a soundness and completeness theorem. Section 2 explains the syntactical concepts, while briefly discussing their motivations. Two standard semantic constructions, Kripke structures and neighbourhood structures, are introduced in Sections 3 and 4, respectively. It is recalled that Aumann's partitional model of CK is a particular case of a definition in terms of Kripke structures. The paper also restates the well-known fact that Kripke structures can be regarded as particular cases of neighbourhood structures. Section 3 reviews the soundness and completeness theorems proved w.r.t. the former structures by Fagin, Halpern, Moses and Vardi, as well as related results by Lismont. Section 4 reviews the corresponding theorems derived w.r.t. the latter structures by Lismont and Mongin. A general conclusion of the paper is that the axiomatization of CB does not require as strong systems of individual belief as was originally thought — onlymonotonicity has thusfar proved indispensable. Section 5 explains another consequence of general relevance: despite the infinitary nature of CB, the axiom systems of this paper admit of effective decision procedures, i.e., they aredecidable in the logician's sense. 相似文献

近20年来,词学研究有所进展,但仍存在一些问题。词学研究应在多重网络中展开。首先,词学是专门之学,但研究者仍需建构开放的知识网络。词乐研究虽有不少成果,但仍处于相对低潮。这与研究者受限于音乐知识,无法有效介入有关。词谱、词律等专门之学亦是如此。其次,可以尝试词学研究的时空延展,打造通观的“全息网络”,通过长时段的、大量的文本分析发现新话题。同时,注意域外汉籍,因为它们可以提供新文献,启发新视角,丰富文本网络。最后,要注意数字人文的发展趋向,要建设词学检索库,善用新技术,更新研究理念,以便及时因应。但数字人文终究只是辅助研究手段,技术取代不了阅读与思考,只有在传统研究的基础上,技术才能发挥更大的作用。 相似文献

Emotion Knowledge, Social Competence, and Behavior Problems in Childhood and Adolescence: A Meta-analytic Review 总被引:1,自引:0,他引:1
The present meta-analytic review examined the magnitude of the relation between discrete emotion knowledge and three of its most commonly studied correlates in childhood and adolescence: social competence, internalizing problems, and externalizing problems. Emotion knowledge demonstrated small to medium-sized relations with each correlate. Moderators of effect size were also examined and included multiple sample and methodological characteristics. Using random effects models, significant moderators of effect size for relations between emotion knowledge and externalizing problems included sample recruitment, sample age, and the source of externalizing problems ratings. Moderators of effect size were not found for emotion knowledge and social competence, and the effect sizes across samples for emotion knowledge and internalizing problems were homogeneous. Results highlight the relatively consistent yet modest relations between emotion knowledge and its correlates. Implications for applied research and new directions for research on emotion knowledge using innovative methods are discussed. 相似文献

共同体的承认是知识生产的根本动力,在西方期刊承认乃共同体承认的有机组成部分,学术人努力生产、发表创新性的知识以赢得共同体的承认.然而在我国,量化考评下的期刊承认并未得到大部分学术人的真正认同,已非共同体承认的一部分,学术人生产知识主要是为了取得形式化的期刊承认以满足各种实用性的目的,而非生产出创新性的知识以赢得实质性的共同体承认,期刊承认与共同体承认之间的冲突导致了我国学术知识生产动力机制的失灵.为了化解两者之间矛盾,我们一方面应使同行评议机制在各种学术评价活动中占据主导地位,另一方面要进一步完善学术期刊的匿名评审制度,以弥合期刊承认与共同体承认之间的断裂,从而真正激励学术知识的生产. 相似文献

知识共享对供应链信用风险传染的影响研究 总被引:1,自引:0,他引:1
将企业间知识共享这一因素引入供应链上下游企业博弈过程,在完全信息条件下研究三级供应链中零售商分别与分销商、制造商进行知识共享时知识共享量与企业信用风险水平和供应链信用风险传染强度之间的关系,并结合算例进行了数值分析.基于Stackelberg博弈模型的研究结果表明,供应链上的知识共享有助于降低供应链成员企业的信用风险;进行知识共享的企业间信用风险传染强度随着知识共享量的增加而增大;企业进行知识共享比不进行知识共享时受到其它企业信用风险传染的影响大. 相似文献

Harry Scarbrough 《英国管理杂志》1998,9(3):219-232
The development of the 'resource-based theory of the firm' has helped to reorient the field of strategic management towards a focus on the organizational processes and structures which produce 'core competencies'. By challenging previous assumptions of market determinism this approach seems to open up the prospect of a greater dialogue with the theories and concerns of organization studies. This paper aims to determine the scope of such a dialogue by developing an appreciation and critique of the core competencies framework from an organizational perspective. In this context, the key feature of resource-based theories is seen to be their focus on organizational knowledge rather than decision-making processes as the engine of competitive performance. This focus has a powerful resonance with studies of knowledge in organizations, particularly those forms of knowledge which are linked to product and process design.
However, despite the important shift towards a knowledge-based view of competition, the core competencies approach fails to follow the logic of its own argument as far as the organizational appropriation of knowledge is concerned. In their pursuit of an ontological model of competitive performance –defining the essential causes of firm competitiveness – resource-based approaches neglect the socially embedded qualities of organizational knowledge. As a result, the social construction of knowledge, encompassing the dilemmas posed by the employment relationship and the pitfalls of institutionalization, is neglected. Instead, a smoothly linear model is developed linking skills, competence and competitiveness. This mechanistic view is further reinforced by reliance on a command and control model of the management process. Organizational knowledge is not a biddable resource at the disposal of top management. 相似文献
