异丙酚不同麻醉深度对学习和记忆的影响

本研究使用加工分离程序探讨了异丙酚不同麻醉深度对学习和记亿的影响。结果发现在无手术刺激存在的情况下,使用异丙酚靶控静脉全身麻醉至OAA／S评分2分(相当于意识消失)时仅使外显记亿消失,提示意识消失时仍存在内隐记亿;麻醉至OAA／S评分1分时可使内隐记亿消失。为避免患者术后对手术中事件有不良回亿,应在解除手术刺激的前提下,麻醉至OAA／S评分1分。

Posttraumatic Stress Disorder and Associated Functional Impairments During Pregnancy: Some Consequences of Violence Against Women

Despite the high prevalence of violence in the lives of women of reproductive age, and the adverse consequences posed to pregnant women suffering from PTSD, few studies have examined violence-related trauma and PTSD among pregnant women. A structured research interview was administered to a convenience sample of 85 prenatal care women to collect information regarding their experiences of violence victimization, PTSD symptoms related to violence-related traumatic events, and whether these symptoms impaired various aspects of the women's daily functioning. Results indicated that 69% of the women experienced a violent traumatic event, with the majority of events occurring before the current pregnancy and being perpetrated by the women's intimate partners. The traumatized women evidenced high levels of PTSD symptoms during pregnancy, with 58% of the women meeting criteria for a PTSD diagnosis. Moreover, many of the women with PTSD symptoms reported that the symptoms adversely affected aspects of their daily functioning.     

大中学生英语阅读的元认知策略发展及其民族差异比较

采用英语阅读的元认知意识问卷对云南省大学生,昆明汉族、丽江地区的纳西族和彝族中学生进行测查。结果表明：(1)大中学生英语阅读的元认知策略水平随着年级的升高呈现出提高的趋势,从中学到大学是元认知策略水平快速发展的时期;(2)男女大中学生英语阅读的元认知策略水平整体上具有一致性,但在中学阶段却呈现出女生略优于男生的趋势,到了大学,男女两性发展基本平衡;(3)汉族与纳西族中学生英语阅读的元认知策略水平整体上具有一致性,彝族中学生英语阅读的元认知策略水平呈现出优于汉族和纳西族的趋势。     

四参数Logistic加权模型下被试能力稳健估计

设计项目参数、被试得分已知的测验情境,在两、三、四参数Logistic加权模型下进行能力估计,发现被试得分等级之间的能力步长存在着均匀的步长间距,被试得分能较好的反映多级记分的分数加权作用。两参数Logistic加权模型下会出现被试参数估计扰动现象,猜测现象会导致能力高估现象,失误现象会导致能力低估现象;三参数Logistic加权模型c型下能力高估现象未出现或不明显;三参数Logistic加权模型γ型下能力低估现象未出现或不明显;四参数Logistic加权模型下被试能力高估现象和低估现象都未出现或不明显,四参数Logistic加权模型是被试能力稳健性估计较好的方法。     

通达与敞开:中西政治哲学中的公共性

古希腊的政治是空间性的,它的公共性概念基于空间的敞开性,并为这种敞开性所规定,这种敞开性使得古希腊的公共性观念具有一种“脱境域”的特征,它指引个人从其在世境域中抽身而退,进入到一个共有之域,因而古希腊的公共性偏向于汉语的“共”。而在中国古典政治哲学中,政治不是空间性的,而是境域性的,由此形成的公共性概念以通达为特征,它表现为敞开性与幽暗性之间的相互通达,这种公共性应理解为不是以“共”为主,而是以“公”为中心。     

试论生态女权主义与道教思想的契合

Effects of Explicit Instructions,Metacognition, and Motivation on Creative Performance

Effects of explicit instructions, metacognition, and intrinsic motivation on creative homework performance were examined in 303 Chinese 10th-grade students. Models that represent hypothesized relations among these constructs and trait covariates were tested using structural equation modelling. Explicit instructions geared to originality were positively related to originality of homework, but not to fluency/flexibility of homework. Participants with high intrinsic motivation for creative work scored higher on originality as well as fluency/flexibility of homework, whereas intrinsic motivation for challenging work had an inverse effect on creative homework. Theoretical claims on the relation between explicit instructions and metacognitive activities and between the latter and creative performance were not supported by this study. The degree of explicitness of instructions and the nature of the tasks were discussed in relation to the findings on the effect of explicit instructions. Further, the difference of creative process involved in the production of original versus fluent/flexible creative performance and the difference in the two types of intrinsic motivation and their effects on creative performance were discussed based on various studies including brain activities. Implications of the findings for the Chinese education system were discussed.     

员工为什么乐于助人?多层次的领导–部属交换对帮助行为的影响

基于社会交换理论,以56名直属主管和274名下属的配对数据为样本,考察了多层次的领导–部属交换对个体和团队层次上的帮助行为的影响及作用过程。跨层次分析结果表明:(1)个体层次的人际公平中介了个体和团队层次的领导–部属交换对员工帮助行为的影响;(2)团队层次的人际公平氛围中介了团队平均领导–部属交换对个体和团队层次的帮助行为的影响;(3)领导–部属交换关系差异化对个体和团队层次的领导–部属交换与帮助行为之间的正向关系均具有显著的负向调节作用,即相对于较高的领导–部属交换关系差异化,较低的领导–部属交换关系差异化强化了个体和团队层次的领导–部属交换对帮助行为的影响。
