Reciprocity of inter-ethnic attitudes in a multicultural society     

J.W Berry  Rudolf Kalin 《Int J Intercult Relat》1979,3(1):99-111

A national survey of multicultural and ethnic attitudes in Canada was conducted in 1974 (n = 1849). Data were analysed for the 1244 respondents whose ethnicity could be determined as Angloceltic, French, German, Italian or Ukrainian Canadian, A five group by five group intergroup attitude matrix was created, with each group acting both as attitude object and as holder of attitudes. Analysis indicated the existence of reciprocity or balance in the matrix: groups tended to reflect the attitude held toward them back onto the group holding the attitude. However this structural balance was moderated by the existence of shared attitudes about the position of a group in the national ethnic hierarchy. Further analysis indicated the existence of ethnocentrism in the matrix: attitudes toward ingroup and positive reference groups were more positive than toward out-groups. Perceived intergroup similarity and familiarity were positively correlated with each other and with intergroup acceptance. Results were discussed in relation to attitude balance theory and ethnocentrism theory, and in their implication for intergroup research in multicultural societies.  相似文献   

Contextual cues and depth of processing in short prose passages     

Raymond W. Kulhavy  Jay L. Sherman  Richard F. Schmid 《Contemporary educational psychology》1978,3(1):62-68

Two experiments compared context and depth-of-processing strategies applied to the learning of short aurally presented prose passages. In the first study, contextual orientation led to significantly higher recall than a continue-paragraph condition, and both strategy groups performed significantly better than a nonstrategy control group. In the second experiment, continuing paragraphs was superior to generating contextual theme statements, with both strategies again superior to the controls. These results were discussed in terms of the ways in which processing demands effect memory for connected discourse.  相似文献   

Communication channels within ethnic groups     

Leo W. Jeffres  K.Kyoon Hur 《Int J Intercult Relat》1981,5(2):115-132

Major channels of communication are examined for two major functions: providing news of the ethnic community, and linking ethnics to the “mother country.” The four major channels are: interpersonal channels (friends and neighbors), radio, local metropolitan daily newspapers, and ethnic-language newspapers. Size of ethnic group is linked to channel preference, and greater ethnicity is related to a preference for ethnic media for both functions. Lower SES ethnics lend to rely more on interpersonal communication and ethnic media, while higher SES ethnics turn more to metro media and magazines. Channel preference as indicated by respondents is also linked to actual usage patterns.  相似文献

丁韪良的科举观及其影响     

虞宁宁 《教育与考试》2010,(6)

曾执掌同文馆和京师大学堂的传教士丁韪良对中国的科举和传统文化情有独钟。他认为中国的科举系统已经成为行政机构的独立分支,有完善的学位授予制度和显著的激励性、竞争性、高收益性、高风险性和民主性等特征;但也暴露出明显的缺点。如果能稍用西术于科场,科举定能极大地推动中国教育事业的发展,带来中国社会的进步与繁荣。丁韪良的科举观不仅影响了美国的文官考试制度,也影响了近代中国的科举和教育改革。  相似文献   

Incompatible Rhetorical Expectations: Julia W. Carpenter's Medical Society Papers, 1895–1899     

Carolyn Skinner 《Technical Communication Quarterly》2013,22(4):307-324

This article examines 3 papers presented before the Cincinnati Academy of Medicine by 19th-century physician Julia W. Carpenter. The article identifies 3 strategies Carpenter used to negotiate the incompatible rhetorical expectations for women and for physicians. The published records of academy discussions provide evidence for Carpenter's colleagues' reactions to each strategy, revealing the complexity of her rhetorical situation and demonstrating the complex links among rhetorical practice, professional identity, and a communicator's social position.  相似文献   

钼表面（Mo,W）Si2-Si3N4复合涂层的低温氧化行为研究     

张厚安  吴艺辉  古思勇  林佳  庄树新 《鹭江职业大学学报》2013,(3):1-4

采用包渗法在钼表面原位制备了（Mo,W）Si2-Si3N4复合涂层,考察了其在大气中于500℃和600℃等温循环的氧化性能,利用XRD和SEM等研究了其组织形貌.结果表明：（Mo,W） Si2-Si3N4涂层具有良好的低温抗氧化性,其在空气中500℃和600℃氧化480 h的氧化速率分别为0.0145 g/（m2·h）和0.0191g/ （m2·h）,归因于涂层氧化表面形成了致密的SiO2膜.  相似文献
