经典力学革命中的概念图式变化

经典力学革命中起核心作用的是运动概念的变化。亚里士多德力学把运动理解成位移,这种运动概念与因果解释图式一起,限定了力学解释的基本特征。为了解决抛体问题而引入的冲力理论是一个过渡,伽利略在用冲力理论解释自由落体运动时改变了思考问题的方向,转向新的运动概念——运动就是瞬时运动。这个概念结合力学解释的因果图式预告了惯性定律。

Formation, consolidation, and diversification of the ethnic elite: The case of the Chinese immigrant community in the United States

The Chinese immigrant community in the United States has gone through several historically significant periods: unrestricted immigration, Chinese exclusion, immigration on restricted quotas, and immigration on equal basis. Each historical period marks a unique pattern of immigrant adaptation and community development, which influences the formation, consolidation, and diversification of the elite. The aim of this article is to illuminate these processes within the greater Chinese immigrant community in the US. Members of the old elite are powerful to the extent that they are not assimilated; yet they remain powerless in the larger society because of their lack of participation. Members of the new elite groups, in contrast, achieve power by integrating themselves economically and socially into the larger society; yet their very integration, often at the expense of ethnic cohesiveness, subjects them to allegation of inferiority from the ethnic hierarchy. Thus they are powerless because they are too assimilated.     

The contributions of multi‐criteria decision making to the development of decision support systems subspecialties: an empirical investigation

This study focuses on examining the structure of decision support systems (DSS) research, with a particular emphasis on assessing the contributions of multi‐criteria decision making (MCDM) to the development of each of the DSS subspecialty areas. This study traces how concepts and findings by researchers in the MCDM area have been picked up by DSS researchers to be applied, extended and refined in the development of DSS research subspecialties. In doing so, factor analysis is applied to an author cocitation frequency matrix derived from a large database file of comprehensive DSS literature. This study concludes that researchers in the MCDM area have made crucial contributions to the development of DSS research subspecialties. Copyright © 1999 John Wiley & Sons, Ltd.     

时间压力和相似性对类比推理直觉加工的影响

通过两个实验探讨了时间压力对类比推理的直觉加工的影响。实验1采用三因素混合实验设计,以48名大学生为被试,在不同时间压力条件下对不同相似性言语类比推理题进行喜好度判断和类比推理逻辑判断。实验2是在实验1的基础上用图形类比推理题代替语义类比推理题,以56名大学生为被试。结果发现:(1)时间压力下,对跨领域言语类比推理的直觉加工效应显著高于逻辑加工效应;(2)时间压力下,低难度图形类比推理题的直觉加工效应显著高于逻辑加工效应。无时间压力条件下,图形类比推理的逻辑加工效应优势明显;(3)时间压力对类比推理的直觉加工和逻辑加工均有影响

Assessing the predictive validity of perceived globalness and country of origin of foreign brands in quality judgments among consumers in emerging markets

Consumers in emerging markets are known to have strong preferences for well‐known foreign brands. Drawing on schema and categorization theories, this study empirically investigates how accessible two components of brand foreignness – globalness and country of brand origin – are in consumer perceptions of brand quality in emerging markets. In addition, we argue that brand globalness can be shaped by inferential reasoning and test how consumer perceptions of brand globalness are affected by both a brand's country of origin and its perceived quality. Two different studies were conducted with young‐adult consumers in China. The study found that in their evaluations of foreign brands consumers are more influenced by country of origin than by brand globalness. It also found that consumers tend to perceive a high level of globalness in high‐quality brands and brands from a favorable country‐of‐origin. Further, this tendency was found to differ between well‐known and lesser‐known brands. These findings confirm the predictive validity of country of origin, but contrast with extant literature on the role of brand globalness as a principal quality cue for foreign brands among consumers in emerging markets. Our findings also imply brand globalness can be an inferred attribute of perceived brand quality and country‐of‐origin image. Keywords: brand foreignness, brand globalness, country‐of‐origin effect, emerging markets.     

Children’s Responses to Computer‐Synthesized Speech in Educational Media: Gender Consistency and Gender Similarity Effects

This study examines children’s social responses to gender cues in synthesized speech in a computer‐based instruction setting. Eighty 5th‐grade elementary school children were randomly assigned to one of the conditions in a full‐factorial 2 (participant gender) × 2 (voice gender) × 2 (content gender) experiment. Results show that children apply gender‐based social rules to synthesized speech. More specifically, children evaluate synthesized speech more positively, trust the speech more, and learn more effectively when voice gender matches either content gender (consistency attraction) and/or their own gender (similarity attraction). Children’s computer self‐efficacy was a significant covariate for their social responses to synthesized speech. Theoretical and practical implications of the current study for the design of educational media are discussed.     

儿童类比推理的影响因素及干预促进

类比推理这一重要认知能力能够帮助儿童在未经历过的复杂情况下进行推断和学习。近年来研究者主要从行为研究、计算机模型和眼动技术的角度探究了儿童抑制控制和工作记忆在类比推理中的交互作用模式及类比推理策略对类比推理的影响。在此基础上,研究者围绕语言标签和物理表征两方面对儿童类比推理进行了干预研究。儿童类比推理的未来研究应着眼于改进研究方法、关注类比推理各加工阶段影响因素及加强儿童类比推理策略的干预应用研究。
