The effect of the nonhuman external regulator’s answer-until-correct (AUC) versus knowledge-of-result (KR) task feedback on children’s behavioral regulation during learning tasks

The present study was conducted to shed a new light on the nonhuman’s external regulation effect on children’s behavioral regulation through investigating the effect of the computer’s task feedback answer-until-correct (AUC) versus knowledge-of-result (KR) with 40 preschool children (boys/girls) divided into AUC-Condition versus KR-Condition. The Aginian’s methodology (Agina, Kommers, & Steehouder, 2010) with the latest updates (Agina, Kommers, & Steehouder, 2011) was used, which involves an isolated, computer-based learning system with three different computer’s agents for measuring self-regulation as a function of the task level selection, self-regulation as a function of task precision, and special agent for evaluating children’s satisfaction. It was hypothesized that AUC-Condition will outperform KR-Condition in verbalization intensity, manifested self-regulation, and the degree of satisfaction. Despite the results were not confirmed the hypothesis, the results generated by the game were consistent with the statistical results in which this consistency increases, to a great extent, the reliability of the Aginian’s measurements. However, both results were not confirmed Vygotsky’s view or Piaget’s view of self-regulation development as both concluded that thinking aloud and self-regulation have a reverse relationship and, therefore, thinking aloud, per se, can be used to explore the problems the children may not agree to talk about.     

基于树核函数的中文语义角色标注

使用SVM提供的卷积树核函数构造一个中文语义角色标注系统,将依存关系作为标注单元进行中文语义角色标注。通过不同的裁剪方法获得依存树的结构化信息,裁剪后的依存树分别为最短路径树和最小树。在中文PropBank和NomBank的转换语料上进行实验,结果表明,该系统在动词性谓词和名词性谓词语料上的F1值分别为83.66和76.87。

钛对硅 锰脱氧FeNi42合金中夹杂物的影响

 通过热力学计算及试验分析,系统研究了不同含量的Ti对Si Mn脱氧FeNi42合金中夹杂物数量、组成、形貌和尺寸分布的影响,利用扫描电镜和图像分析仪对试样中的夹杂物进行了检测。结果表明,当合金中钛含量较低时,夹杂物的中心部分是析出温度较高的Al Ti Mn复合氧化物,向外依次是锰硅酸盐和少量的MnS。随着钛含量的增加,夹杂物中钛含量逐渐增多,而Mn、Si等元素的含量逐渐减小。Ti的加入使合金中夹杂物的数量增多,尺寸减小,且呈均匀弥散分布。     

CSP工艺冷轧薄板盐浴退火再结晶实验

 研究了以CSP工艺热轧板卷为原料的冷轧薄板在盐浴退火过程中的再结晶行为,通过显微组织、显微硬度及电子背散射衍射技术观察、分析揭示了再结晶的规律,结果表明,CSP工艺冷轧薄板经盐浴退火后的再结晶组织为等轴状晶粒;在相同温度下盐浴退火,冷轧压下率较大时,完成再结晶所需的保温时间较短,再结晶晶粒细小。
