肺血栓栓塞症是常见的临床病症,因其临床表现多样,易发生误诊漏诊而导致较高的病死率。但“凡事预则立,不预则废”,充分掌握肺血栓栓塞症的知识、以正确的思维方式引导临床诊疗可以有效减少和避免误诊漏诊。 相似文献

Standard Kripke models are inadequate to model situations of inexact knowledge with introspection, since positive and negative
introspection force the relation of epistemic indiscernibility to be transitive and euclidean. Correlatively, Williamson’s
margin for error semantics for inexact knowledge invalidates axioms 4 and 5. We present a new semantics for modal logic which
is shown to be complete for K45, without constraining the accessibility relation to be transitive or euclidean. The semantics corresponds to a system of
modular knowledge, in which iterated modalities and simple modalities are not on a par. We show how the semantics helps to
solve Williamson’s luminosity paradox, and argue that it corresponds to an integrated model of perceptual and introspective
knowledge that is psychologically more plausible than the one defended by Williamson. We formulate a generalized version of
the semantics, called token semantics, in which modalities are iteration-sensitive up to degree n and insensitive beyond n. The multi-agent version of the semantics yields a resource-sensitive logic with implications for the representation of common
knowledge in situations of bounded rationality. 相似文献

There is a large and growing body of research to show that human resource (HR) practices affect individual performance, organisational productivity and organisational performance. Academic findings about effective HR practices, however, have not readily been adopted by practitioners. A variety of theoretical and practical explanations have been advanced about the research–practice gap. Research by Rynes, Colbert, and Brown (2002) suggested that the research–practice gap is due to a lack of knowledge, but the extent to which these findings apply to the Australian context is unknown. The sample consisted of 102 industrial/organisational (I/O) psychologists and 89 HR practitioners. The main aim of the present study was to replicate and extend the work of Rynes et al. by examining and comparing the knowledge of I/O psychologists and HR practitioners. It was found that overall I/O psychologists were better informed about HR research than HR practitioners; in particular, they were more knowledgeable about management practices and recruitment and selection. In both groups, of the five content areas examined (Management Practices; General Employment Practices; Training and Development; Recruitment and Selection; and Compensation and Benefits), the greatest gaps were in Recruitment and Selection. 相似文献

Abstract: Susana Nuccetelli discusses critically my account of Moore's Proof of the External World. Noah Lemos takes up my views on skepticism and my distinction between animal knowledge and reflective knowledge. Otávio Bueno focuses on my treatment of dream skepticism. In this article I offer replies to my three critics. 相似文献

Paul Boghossian discusses critically my account of intuition as a source of epistemic status. Stewart Cohen takes up my views
on skepticism, on dreams, and on epistemic competence and competences and their relation to human knowledge. Hilary Kornblith
focuses on my animal/reflective distinction, and, along with Cohen, on my comparison between how dreams might mislead us and
how other bad epistemic contexts can do so. In this paper I offer replies to my three critics.

This paper investigates the role of static and dynamic attributes for the animate-inanimate distinction in category-based reasoning of 7-month-olds. Three experiments tested infants’ responses to movement events involving an unfamiliar animal and a ball. When either the animal or the ball showed self-initiated irregular movements (Experiment 1), infants expected the previously active object to start moving again. When both objects were moving together in an ambiguous motion event (Experiment 2), infants expected only the animal to start moving again. Initial looking preferences for each object did not influence results. When either the facial features of the animal were removed, or its furry body was replaced by a plastic spiral in an ambiguous motion event (Experiment 3), infants formed no clear expectation regarding future movements. Based on this set of findings we conclude that 7-month-olds flexibly combine information about the static and dynamic properties of objects in order to reason about motion events. 相似文献

Research to date has proposed four main variables involved in reading development: phonological awareness, naming speed, orthographic knowledge, and morphological awareness. Although each of these variables has been examined in the context of one or two of the other variables, this study examines all four factors together to assess their unique contribution to reading. A sample of children in Grades 4, 6, and 8 (ages 10, 12, and 14 years) completed a battery of tests that included at least one measure of each of the four variables and two measures of reading accuracy. Phonological awareness, orthographic knowledge, and morphological awareness each contributed uniquely to real word and pseudoword reading beyond the other variables, whereas naming speed did not survive these stringent controls. The results support the sustained importance of these three skills in reading by older readers. 相似文献

We investigated whether 6-year-olds’ understanding of perceptual aspectuality was sufficiently robust to deal with the presence of irrelevant information. A total of 32 children chose whether to look or feel to locate a specific object (identifiable by sight or touch) from four objects that were hidden. In half of the trials, the objects were different on only one modality (e.g., four objects that felt different but were the same color). In the remainder of the trials, the objects also differed (partially) on one irrelevant modality (e.g., four objects that felt different, two red and two blue, where the goal was to locate the soft object). Performance was worse on the latter trials. We discuss children’s difficulty in dealing with irrelevant information. 相似文献

世界知识在句子理解中的整合时程 总被引:1,自引:0,他引:1
Hagoort等(2004)应用背离范式发现世界知识和单词意义在句末的整合是同时进行的。本研究将背离信息提前到句首短语中,旨在探讨世界知识在句子阅读过程中被整合的时程特征。实验采用四词句子为材料,其中第二个词(目标词)含有单词意义或世界知识背离信息,记录并比较被试在阅读后三个词时诱发的脑电变化。结果发现:与正确句子比较,无论是单词意义背离还是世界知识背离,背离目标词均引发出经典的N400,二者在峰值时间和始潜时上无显著差异,但世界知识背离信息诱发的N400波幅值相对较小。句中的后继单词不再诱发类似的N400;但到句子结尾,两类含有背离信息句子的句末正常单词又诱发出类似N400的一个负波。结果提示,在句子理解过程中,世界知识的整合与单词意义的整合相似,可能是随着句子理解过程即时进行的,整合的结果不影响后继信息的加工;但到了句末,读者在对整个句子内容作真实性判断时会对先前进行过的整合再进行考察。 相似文献
