This study examines Mehrabian's claim concerning the cross-cultural generality of implicit metaphors that underlie a set of coding rules for the interpretation of nonverbal behaviors. Responses of Japanese and American school teachers were used to discover whether observers from two different cultures interpret nonverbal behaviors during interpersonal communication according to the three-dimensional metaphorical scheme proposed by Mehrabian and to assess the degree of intercultural consensus about dimensions and interpretations. Factor analysis, factor structure comparisons, and multiple discriminant analysis yielded evidence of significant differences between groups both in the dimensions used and in the interpretations of nonverbal cues along those dimensions.  相似文献

本文研究了Banach空间中的K-正定算子方程解的一种逼近方法。我们把K 正定算子的概念从Hilbert空间,实可分严格凸的Banach空间和实可分q一致光滑Banach空间(q>1)推广列了实可分Banach空间X。对这样的X,我们构造了一个强收敛于方程Ax=f,f∈X,的唯一解的迭代程序(其中A是一个Kpd算子,与K有相同的定义域)。在一定条件下,本文把Petryshyn,Chidume和Aneke,Chidume和Osilike等的相应结果推广到了实可分的Banach空间  相似文献

Many powerful methods and tools exist for extracting meaning from scientific publications, their texts, and their citation links. However, existing proposals often neglect a fundamental aspect of learning: that understanding and learning require an active and constructive exploration of a domain. In this paper, we describe a new method and a tool that use data mining and interactivity to turn the typical search and retrieve dialogue, in which the user asks questions and a system gives answers, into a dialogue that also involves sense-making, in which the user has to become active by constructing a bibliography and a domain model of the search term(s). This model starts from an automatically generated and annotated clustering solution that is iteratively modified by users. The tool is part of an integrated authoring system covering all phases from search through reading and sense-making to writing. Two evaluation studies demonstrate the usability of this interactive and constructive approach, and they show that clusters and groups represent identifiable sub-topics.  相似文献

为处理线性不可分、结构复杂的数据集,提出基于核聚类的K 均值聚类(Kernel Clustering based K means Clustering,KCKC).该方法先在原始空间中对模式进行聚类,再由径向基函数(Radial Basis Function, RBF)核把它们映射到核空间,从而保持大部分模式之间的关系.把提出的方法应用到基于RBF的神经网络(RBF based Neural Network,RBFNN)、基于RBF的支持向量机(RBF based Support Vector Machine, RBFSVM)和核最近邻分类器(Kernel Nearest Neighbor Classifier,KNNC)中,结果表明本文提出的算法可以生成更有效的核,节省在核空间中的核生成时间,避免核数目设置的敏感性,并提高分类性能.  相似文献

Abstract

‘Asian Pop’ cultural products, which include a wide range of media artifacts such as film, music, television drama, comic books, magazines, websites and fashion, have emerged as a popular choice for youth in Asia in recent times. These cultural artifacts feature prominently in the lives of urban youth in major metropolitan centers throughout Asia. This paper examines how Thai youths have become consumers of Korean pop (K‐pop), following the trend of neighboring countries. The popularization of Japanese pop (J‐pop), Taiwanese‐pop and more recently, K‐pop, is welcomed by the Cultural Industry as a sign of expanding borders and as a major step towards expanding its Asian market. On the one hand, growing consumption and mainstreaming of Asian pop might become problematic due to the notion of cultural ‘McDonaldization’/standardization, in the future. On the other hand, perhaps nationalism and national ties will manage to overrule this projected standardization. This paper explores the Thai youth’s consumption of K‐pop in the process of cultural appropriation vis‐à‐vis their ‘national’ cultural formation in changing socio‐cultural contexts.  相似文献
