Intellectual property has historically been a self-contained policy at the international level. With the introduction of the TRIPs Agreement in 1994 and developments since the conclusion of the TRIPs Agreement, the relationship between intellectual property policy and other areas of public policy has become much more complex and interactive. This shift reflects the centrality of intellectual property in the knowledge economy, the rapid development of enabling technologies, notably the Internet and biotechnology, and the advent of the networked society. The consequences of this shift are manifold and herald the increased sophistication and complexity that may be expected of intellectual property regimes in the knowledge economy. An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights and Patents,” held in Warsaw, Poland on 23–24 April, 2004.  相似文献

The type of information (taxonomic or thematic) available at different levels of knowledge was investigated. Following extensive norming to identify taxonomic and thematic associates of low-frequency nouns, participants determined if taxonomic or thematic associates were meaningfully related to target words at three levels of knowledge: target words they correctly defined (known), recognized as familiar (frontier), or mistakenly denied as part of the language (unknown). In another experiment, participants reported which type of relationship (taxonomic or thematic) was preferred. Results indicated that both types of information were available at all levels of knowledge. However, accuracy and preference were greater for taxonomic associates across word levels. A differential increase in available thematic information relative to taxonomic information was found. Implications for the acquisition and representation of word meanings are discussed.  相似文献

Groups of first-grade (mean age = 82 months), third-grade (mean age = 107 months), and fifth-grade (mean age = 131 months) children with a learning disability in mathematics (MD, n = 58) and their normally achieving peers (n = 91) were administered tasks that assessed their knowledge of counting principles, working memory, and the strategies used to solve simple (4+3) and complex (16+8) addition problems. In all grades, the children with MD showed a working memory deficit, and in first grade, the children with MD used less sophisticated strategies and committed more errors while solving simple and complex addition problems. The group differences in strategy usage and accuracy were related, in part, to the group difference in working memory and to group and individual differences in counting knowledge. Across grade-level and group, the switch from simple to complex addition problems resulted in a shift in the mix of problem-solving strategies. Individual differences in the strategy mix and in the strategy shift were related, in part, to individual differences in working memory capacity and counting knowledge.  相似文献

This paper considers a new class of agent dynamic logics which provide a formal means of specifying and reasoning about the agents activities and informational, motivational and practical aspects of the behaviour of the agents. We present a Hilbert-style deductive system for a basic agent dynamic logic and consider a number of extensions of this logic with axiom schemata formalising interactions between knowledge and commitment (expressing an agent s awareness of her commitments), and interactions between knowledge and actions (expressing no learning and persistence of knowledge after actions). The deductive systems are proved sound and complete with respect to a Kripke-style semantics. Each of the considered logics is shown to have the small model property and therefore decidable.Presented by Ewa Orlowska  相似文献

Characterizing the relationship between form-based linguistic knowledge and representation of context has long been of importance in the study of on-line language processing. Recent experimental research has shown evidence of very rapid effects of referential context in resolving local indeterminacies on-line. However, there has been no consensus regarding the nature of these context effects. The current paper summarizes recent work covering a range of phenomena for which referential contrast has been shown to influence on-line processing, including prenominal and postnominal modification, focus operators, and intonational focus. The results of the body of work suggest that referential context effects are not limited to situations in which the linguistic form of the utterance directly specifies the point of contact with context. Rather, context effects of a pragmatic, Gricean nature appear to be possible, suggesting the relationship between linguistic form and context in rapid on-line processing can be of a very indirect nature.  相似文献

支撑—活动观、社会共享认知观以及实践共同体观是当前情境理论中具有代表性的迁移观点。这些观点分别从不同的角度强调情境特性对迁移的影响,并主张在常规的学校教育中突出情境、尤其是社会文化与社会实践情境的作用。  相似文献
