The dialog between Staddon (2001, 2004) and Baum (2004) raises general questions about the nature of scientific peer review. Their dialog displays effects on peer review of differences of opinion about the relative merits of local and global analyses. Baum (1995, 1997, 2001, 2002) favors global analyses as a paradigm different, newer, and better than the local, dynamic, real‐time approach that plays a significant role in Staddon (2001). According to the Kuhnian perspective (Kuhn, 1996) Baum advocates, we can better understand his review of Staddon (2001) by considering the implications for it of his commitment to the idea that a global analysis is a superior scientific paradigm. This commentary examines some characteristics of local and global analyses, as well as some of their possible implications for peer review in the context of a reviewer's belief in the Kuhnian idea of incommensurability: According to this idea, a reviewer who either is, or who believes he is, from one paradigm is unlikely, for better or worse, to understand or perhaps even tolerate work from a different paradigm. It is recommended that a process be developed to encourage “truth in peer reviewing” to reduce possible conflicts of interest embedded in the current conception of scientific peer review.  相似文献

女护士生性教育现状及需求的调查分析   总被引:2,自引:0,他引:2  
本研究以大连某卫校女护士生为研究对象,采用自编式问卷对女护士生的性教育现状及需求进行了调查分析.结果表明:卫校女生在性知识、性态度、性行为方面发展的主流是好的、健康的,但也有少数女护士生对自身正常的性生理、性心理现象不了解而产生心理困惑和压力,女护士生渴望从学校得到正规的性教育.为了使女护士生身心得到健康发展,学校必须开展以性道德教育为核心的正规的性教育.  相似文献

This study examines the hypotheses that (1) 17 domains of general knowledge can be identified; (2) these are positively intercorrelated and form a general factor of general knowledge; (3) there are sex differences in the different domains of general knowledge; and (4) males have more general knowledge in more of these domains than females and in the general factor. The study tests these hypotheses on a sample of 302 German high school students. All the hypotheses were confirmed. All the domains of general knowledge were positively intercorrelated. A general factor was found that explained 31.3% of the variance. Males achieved significantly and substantially higher scores than females in general knowledge of 0.60d. The only area in which females scored significantly higher than males was Nutrition for which there was a medium size effect size (d=0.50). The results are highly similar to those among university students in Northern Ireland reported by Lynn, Irwing, and Cammock (2002).  相似文献

Elman (2009) proposed that the traditional role of the mental lexicon in language processing can largely be replaced by a theoretical model of schematic event knowledge founded on dynamic context-dependent variables. We evaluate Elman's approach and propose an alternative view, based on dual coding theory and evidence that modality-specific cognitive representations contribute strongly to word meaning and language performance across diverse contexts which also have effects predictable from dual coding theory.  相似文献

The paper deals with the issue of practical knowledge for enabling participation. Participation as a strategy for change is widespread in community, health and human service contexts. Research to date has focused on the mechanisms of beneficiaries' participation (e.g. identity, empowerment, activity, gender, space). However, participation as an engagement strategy is action oriented and requires high levels of interaction between those creating the conditions for participation and those participating. These conditions need to be continuously adjusted and outcomes are often unpredictable. This process of ‘working with’ is often dealt with as a technical issue and captured in metaphorical language. Less emphasis has been given to the type of knowledge modalities that might be necessary in order to enable participation. Drawing on an ethnographic case study of participation in a youth inclusion programme the paper explores the role of stories as potential indicators of practical knowledge. The paper argues that enabling young people's participation requires intuition and imagination, patience and perseverance, and judgement for acting under uncertainty. It concludes that stories only partially fulfil their potential as indicators of such knowledge modalities. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

The use of rational agents for modelling real world problems has both been heavily investigated and become well accepted, with BDI (Beliefs, Desires, and Intentions) Logic being a widely used architecture to represent and reason about rational agency. However, in the real world, we often have to deal with different levels of confidence in the beliefs we hold, desires we have, and intentions that we commit to. This paper extends our previous framework that integrated qualitative levels of beliefs, desires, and intentions into BDI Logic. We describe an expanded set of axioms and properties of the extended logic. We present a modular structure for the semantics which involves a non-normal Kripke type semantics that may be used for other agent systems. Further, we demonstrate the usefulness of our framework with a scheduling task example.  相似文献

研究学科领域知识丰富性不同的学生在问题表征过程中信息表征层次的特点。采用“学习-再认”范式,以5类等式为材料,62名初二学生参与实验。结果:两组被试对表面和原理特征一致的等式产生明显的错误再认;对表面特征不一致等式的错误率明显减少。无论原理特征是否一致,两组对表面特征一致等式的反应时无显著差别,但在正确率上丰富组的更高。说明,两组均以有序的系列加工方式编码信息,优先编码表面特征。贫乏组对原理特征的编码干扰表面特征的加工,因而原理特征被丢弃。丰富组加工表面特征则无干扰现象出现,两种特征均能作为再认线索。  相似文献
