目的探讨用三种不同方法取痰培养对明确下呼吸道感染病原菌的价值.方法对58例下呼吸道感染的患者进行了三种不同方法取样培养.结果普通自然咳痰培养(下文简称PZK)标本合格54例,占93.1%;培养阳性16例,占29.63%;用复方洗必泰含漱液漱口后取样(下文简称FXHY)标本合格56例,占96.55%;培养阳性28例,占50%;用经纤支镜防污染毛刷取样(下文简称FBPSB)标本合格58例,占100%;培养阳性32例占55.2%,FXHY与PZK比较P＜0.05有差异,FXHY与FBPSB比较P＞0.05无差异,且FXHY与FBPSB阳性符合率为81.3%.结果FXHY取痰法是一种简便易行,且阳性较高的一种方法.     

Examination Result Attribution,Expectancy and Achievement Goals among Chinese Students in Hong Kong∗

The structure of Chinese primary school students’ causal attributions for actual examination results was examined. A factor analysis of the attributions revealed dimensions which supported Weiner's classification. Age‐related differences as well as interrelationships among perceived attainment, expectancy of success, causal attributions and achievement goals were also explored. Results showed that older students had lower but more accurate perceived attainment than younger students. They also attributed more to internal causes and study at home, and they had stronger learning goals. Results also showed that leaming‐oriented students attributed more to internal causes and study at home but less to home conditions, while performance‐oriented students attributed more to uncontrollable causes. Results were explained and discussed with reference to the socialisation patterns in the Chinese culture.

     

The Effect of Teachers’ Evaluative Feedback on Chinese Students’ Perception of Ability: a cultural and situational analysis

The research explored the effect of teachers’ evaluative feedback on students’ perception of ability. The subjects were 758 Chinese students from elementary schools, high schools, and a university in Hong Kong. Subjects rated ability and effort of two hypothetical students who achieved identical results (success or failure) in a mathematics test but received different feedback (praise, blame, or neutral feedback) from the teacher. They also rated the teacher's perception of their own and their friends’ ability and effort in a similar situation after a real mathematics test. The results of this study support previous findings which indicate that ability perception is influenced by cultural and contextual variables. Contrary to the findings with Western students, ability and effort were positively correlated. The importance of effort among the Chinese students appears to mitigate the effects of teachers’ feedback on students’ ability. Age‐related differences were also observed. The results are discussed in terms of sociocultural background of the subjects.

《三国志·魏志》否定副词的特点

以《三国志·魏书》中的全部否定副词为研究对象,试图认识中古汉语否定副词的一些特点。通过对这些否定副词的分析描写,发现常用否定副词只有“不、非、勿、未”等,和上古相比,数量减少了,分工更明确,反映了中古汉语否定副词向整齐化方向发展的趋势。
