层级一致性指标的多级评分拓展

在认知诊断评估实践中,属性层级合理性的验证非常重要,而现有指标仅停留在0-1计分测验,无法适应考试形式和评分方式多样化的实践需求。研究将0-1计分层级一致性指标（MHCI）拓展至多级计分的层级一致性指标（GHCI）,模拟和实证研究结果表明：（1）GHCI具有和MHCI相同的本质含义,考虑了父项目和子项目得分的多种可能性,从而将MHCI纳入GHCI体系;（2）在多级或混合计分情境,MHCI会有信息损失,容易发生低估,且易受转换比例的影响;（3）GHCI在模拟和实践情境均具较好的适宜性,拟合截断值的设置可依属性层级而定。     

Does inversion affect boundary extension for briefly-presented views?

Inverting scenes interferes with visual perception and memory on many tasks. Might scene inversion eliminate boundary extension (BE) for briefly-presented photographs? In Experiment 1, an upright or inverted photograph (133, 258, or 383?ms) was followed by a 258 ms masked interval and a test photograph showing the identical view. Test photographs were rated as “same”, “closer”, or “farther away” (5-point scale). BE was just as great for inverted as upright views at the 133 and 383 ms durations, but surprisingly was greater for inverted views at the 258 ms duration. In Experiment 2, 258-ms views yielded greater BE when the study photographs were always tested in the opposite orientation, indicating that the difference in BE was related to encoding. Results suggest that scene construction beyond the view boundaries occurs rapidly and is not impeded by scene inversion, but that changes in the relative quality of visual details available for upright and inverted views may sometimes yield increased BE for inverted scenes.     

Consumers’ Response to an Advertisement Using Brand Popularity in a Foreign Market

Abstract : This research examined how domestic consumers respond to an advertisement using brand popularity in a foreign market. By using structural equation modeling, it shows that the consumers’ response can change as a function of three characteristics of brand popularity in a foreign market: (a) expertise of foreign consumers, (b) similarity between domestic consumers and foreign consumers, and (c) animosity to a foreign country. Meanwhile, the similarity effect is found to be stronger for high‐preference heterogeneity than low‐preference heterogeneity. This research documents the importance of understanding the underlying mechanism to determine the effects of brand popularity in a foreign market on brand attitude and purchase intention.     

Extending Fitts' law to a three-dimensional pointing task

An attempt was made to extend Fitts' law to a three-dimensional movement (pointing) task to enhance its predictive performance in this domain. An experiment was conducted in which 10 subjects performed three-dimensional pointing movements under the manipulation of target size, distance to target and direction to target. As expected, the duration of these three-dimensional movements was rather variable and affected markedly by direction to target. As a result, the variance in the movement times produced was not satisfactorily explained by the conventional Fitts' model. The conventional model was extended by incorporating a directional parameter into the model. The extended model was shown to better fit the data than the conventional Fitts' model, both in terms of r(2) and the standard error of the residual between the measured movement time and the value predicted by model fit.     

Consumer evaluation of net utility: Effects of competition on consumer brand selection processes

This study explores how brand-related information is integrated within a competitive environment. Specifically, we develop a structural equation model of competition between two brands, which includes each brand's price-quality characteristics (i.e., net utility). The model simultaneously tests how the net utility of the focal and competing brands affects consumers' attitudes, intentions, and choice regarding the focal brand. This study extends existing research with the findings that price-quality evaluations of a focal brand and net utility perceptions of competing brands influence consumers' attitudes, intentions, and choice regarding the focal brand. Thus, in order to attract consumers to their brands, marketers should focus not only on improving the performance and net utility of their own brands, but also on studying competing brands in the marketplace.     

Consumers' product evaluation: a study of the primary evaluative criteria in the precious jewellery market in the UK

It is normally argued that consumers make their purchase decisions on the basis of their evaluation of, and knowledge about, the product attributes. This paper reports findings from a research study, which was conducted to determine the nature and type of evaluative criteria used by an individual while purchasing a piece of precious jewellery. In doing so, the study looked into the significance of product category knowledge, brand familiarity and brand consciousness in product evaluation. A questionnaire was sent to 500 consumers of precious jewellery in five major cities of the UK. Results indicate that, in general, subjective attributes are more important for people buying precious jewellery than the objective attributes. The significance of specific attributes during product evaluation could vary according to one's level of product category knowledge, brand familiarity and brand consciousness. The paper discusses implications for the marketers. Copyright © 2001 Henry Stewart Publications.     

Duality for Double Quasioperator Algebras via their Canonical Extensions

This paper is a study of duality in the absence of canonicity. Specifically it concerns double quasioperator algebras, a class of distributive lattice expansions in which, coordinatewise, each operation either preserves both join and meet or reverses them. A variety of DQAs need not be canonical, but as has been shown in a companion paper, it is canonical in a generalized sense and an algebraic correspondence theorem is available. For very many varieties, canonicity (as traditionally defined) and correspondence lead on to topological dualities in which the topological and correspondence components are quite separate. It is shown that, for DQAs, generalized canonicity is sufficient to yield, in a uniform way, topological dualities in the same style as those for canonical varieties. However topology and correspondence are no longer separable in the same way. Presented by Robert Goldblatt     

类似性比较对3～5岁儿童内隐推理的影响

本研究以三个实验探讨了3～5岁儿童词汇学习的内隐推理过程。实验1首先让被试者看一个熟悉物体的标准图片,分别以熟悉的或者不熟悉的名词命名,然后要求从两个选项中选择一个图片与标准图片匹配。结果表明3～4岁儿童可以不熟悉名词完成词汇扩展作业,但是只有5岁儿童可以熟悉名词完成词汇扩展作业,这表明5岁儿童可能有一个内隐推理加工过程。实验2以不熟悉物体作为标准图片,以熟悉名词与指代词分别作为指导语进一步测试5岁儿童的内隐推理过程,结果表明这个年龄阶段儿童的类概念形成有一种自上而下加工的内隐推理过程。实验3呈现基本概念的图片检验什么因素影响3～5岁儿童词汇学习的内隐推理过程,结果表明在类似性比较条件下与3～4岁儿童相比,5岁儿童更加明显地表现了内隐推理的加工过程。最后以类似性理论讨论了本研究的结果。
