认知偏误对创业者学习与企业绩效的调节效应

基于闽南的样本数据,运用结构方程分析方法,创业者认知偏误对创业学习与绩效关系的调节效应得到检验。研究结论认为,创业者认知偏误的调节作用主要发生在信息加工、输出与反馈过程中。具体而言,创业加工与输出偏差一般会削弱开发学习与短期绩效之间的关系．从而使得创业者变得更加冒险。信息反馈偏误通过强化探索学习与短期绩效负相关关系,来影响创业决策。

从"老大学"到"老中学"……(雁斋读书漫笔之一)

从启蒙到小学,再到中学而后大学,是人生道路上至关重要的阶段.本文通过分析《过去的中学--人生最关键阶段的教育和学习》《胡适选专业:大师们的大学生活》二书,回顾了施雅风、张维、钱穆、张思之、钱学森等成名人物自由学习,各具人文风采的中学生活,以及胡适、蒋梦麟等大师在大学里随意选择和调换科系的自由选学做法,意欲给现在的中学教育活动提供一点启迪意义,指出在高等教育制度上,学生如何选择科系,在中国的现当代是有着严重断裂的.     

General and Specific Factors in Reading Comprehension

One explanation for why many students routinely choose to do their homework with a radio or TV operating is that this distraction facilitates studying. To investigate the validity of this explanation, the authors carried out two experiments with sixth-grade students who worked on two difficulty levels of individualized mathematics assignments (N = 12) and reading assignments (N = 9) under three distraction conditions: quiet; self-selected, self-regulated radio; and self-selected, self-regulated TV. The data yielded no evidence of sizable distractor effects on students' time spent studying, computational accuracy, reading comprehension, or reading rate. These results generally are consistent with the theoretical conceptualization of attention as flexible and adaptable.     

A cross-cultural investigation of teachers’ and reporting officers’ self-ratings on teaching and leadership skills across Singapore and Bahrain

Self-rating bias is particularly likely in organizational behavior research as individuals tend to inflate their expertise, skills and character. This study aims to examine how two culturally diverse groups of teachers and their reporting officers respond to self-ratings of their own teaching skills and leadership skills respectively. It is posited that such response may be culturally based. To ensure validity of comparisons, analyses were done using linear Rasch measures in logits rather than the non-linear raw scores. No significant differences were found between the perceptions of Singaporean teachers and their reporting officers on teaching and leadership skills. The Bahraini data however revealed teachers’ perceptions of own teaching skills were significantly higher than that of their reporting officers. The opposite is true for the Reporting officers’ perceptions of our leadership skills. Bahraini teachers’ perceptions of their own teaching skills were also found to be significantly higher than that of their Singaporean counterparts. The findings support the notion that individuals’ thinking and behavior is influenced by how they process social and cultural information.
