康海《王兰卿》杂剧的创作时间与缘起考

《王兰卿》是明中期著名曲家康海创作的一部杂剧。一直以来,研究者对此剧的关注不多,且多以节义剧视之。《王兰卿》杂剧是根据明中期陕西盩厔王兰卿的真实事迹创作而成,其创作时间当在嘉靖元年至嘉靖八年五月间。康海一生志节凛然,去官后以史官自命、淑世之志不减。杂剧《王兰卿》的创作缘起当是康海为王兰卿的事迹所激,并因王氏得不到官府的"旌表"而不平,故而作剧演之,助其不朽。     

Population differences in constructive memory

An experiment was conducted to evaluate constructive memory in fourth-grade low-SES black and middle-SES white children. The children were read nine short passages; each passage was composed of two premise statements and a filler sentence. The children were tested by a recognition procedure. Thirty-six test sentences were presented randomly. Four sentences were associated with each passage (true premise, false premise, true inference, and false inference). Subjects were asked to make yes/no recognition decisions based on whether the test sentence was identical to a sentence presented at study. Middle-SES white children made few errors, except to true inference test sentences. This pattern of performance is consistent with the constructive view of memory. Low-SES black children also had a high error rate to true inference items. However, this outcome may not reflect constructive memory because they also had a high error rate to some of the other types of test sentences.     

《玄应音义》碛砂藏系改动原文文字情况考察

就碛砂藏系改动原书文字的情况考察《玄应音义》碛砂藏、高丽藏二系的异同,其改动原书文字的情况可归为三种：根据时音改动释文切语;不明底本之误而以意妄改;据字书删改玄应训释失当之处。充分认识碛砂藏系这些改动的性质,把握其改动的大致规律,不但能让我们对其版本系统特点有更清楚的认识,而且能正确指导《玄应音义》校勘整理工作。     

后学之津梁诗家之宝筏——论《诗韵合璧》的文献价值及诗学功能

清人汤文璐所编的《诗韵合璧》是近代最富影响的旧体诗写作辅助工具书。该书不仅汇辑了《词林典腋》《诗腋》《虚字韵薮》等多种书籍,而且还利用《诗韵异同辨》《诗韵音义注》等书籍对字、韵进行校勘、考正,最终熔诸书优长为一炉,具有较高的文献价值。《诗韵合璧》在体例取材等方面的鲜明特性,可从中窥得清代中晚期诗坛的某些时代特征与编选思想,对提升当下旧体诗写作的基础水平亦具有借鉴意义。     

∑~-超子原子能级研究

对于奇异原子可近似视为Rydberg原子,并考虑Rydberg电子与原子实间的相互作用,由此方法计算核极化用以修正C.J.Batty光学模型势下的∑-208PB及∑-184W能级跃迁,其结果比用经典的方法计算出来的结果要精确得多,为超子原子的深入分析提供了理论上的依据.

Reciprocity of inter-ethnic attitudes in a multicultural society

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.
