Prospective issues for error detection

From the literature on error detection, the authors select several concepts relating error detection mechanisms and prospective memory features. They emphasize the central role of intention in the classification of the errors into slips/lapses/mistakes, in the error handling process and in the usual distinction between action-based and outcome-based detection. Intention is again a core concept in their investigation of prospective memory theory, where they point out the contribution of intention retrievals, intention persistence and output monitoring in the individual's possibilities for detecting their errors. The involvement of the frontal lobes in prospective memory and in error detection is also analysed. From the chronology of a prospective memory task, the authors finally suggest a model for error detection also accounting for neural mechanisms highlighted by studies on error-related brain activity.     

Supervisory control of multiple robots in dynamic tasking environments

A military targeting environment was simulated to examine the effects of an intelligent route-planning agent RoboLeader, which could support dynamic robot re-tasking based on battlefield developments, on the performance of robotics operators. We manipulated the level of assistance (LOAs) provided by RoboLeader as well as the presence of a visualisation tool that provided feedback to the participants on their primary task (target encapsulation) performance. Results showed that the participants' primary task benefited from RoboLeader on all LOAs conditions compared to manual performance; however, visualisation had little effect. Frequent video gamers demonstrated significantly better situation awareness of the mission environment than did infrequent gamers. Those participants with higher spatial ability performed better on a secondary target detection task than did those with lower spatial ability. Finally, participants' workload assessments were significantly lower when they were assisted by RoboLeader than when they performed the target entrapment task manually. Practitioner Summary: This study demonstrated the utility of an intelligent agent for enhancing robotics operators' supervisory control performance as well as reducing their workload during a complex urban scenario involving moving targets. The results furthered the understanding of the interplay among level-of-autonomy, multitasking performance and individual differences in military tasking environments.     

抗肝癌hdsFv-hEDN重组免疫毒素的表达及生物学活性

目的制备对人肝癌细胞具有特异性杀伤活性的抗肝癌重组免疫毒素。方法利用大肠杆菌系统表达抗肝癌hdsFvhEDN基因重组免疫毒素。表达产物经NiNTA亲和层析纯化后,进行特异性杀伤活性检测。结果抗肝癌hdsFvhEDN重组免疫毒素以可溶性形式表达于大肠杆菌培养上清中,并获得有效纯化。ELISA法检测证实其具有与相应抗原特异性结合的活性。细胞毒试验表明对肝癌细胞具有杀伤作用,而对正常肝细胞无损伤。结论已成功地制备了具有特异性结合和杀伤活性的抗肝癌hdsFvhEDN基因重组免疫毒素,为其进一步应用奠定基础。

对我国高等职业教育人才培养的分析与思考

高等职业教育是我国现代高等教育的重要组成部分,其培养目标是实用型、应用型的高级专门人才。如何使高等职业教育培养的人才更适应社会经济发展的需要是摆在每一所高职学校面前的重要课题。文章认为目前高职教育的办学层次未尽合理,人才培养过程难以反映出职业技术教育的特点,并就此提出了若干建议。     

行为经济学——一门新兴的学科

进入９０年代以来，经济的发展又一次推动着经济理论的发展和演变．新经济的现象不断出现，使得经济学靠模型和计算机未能找到解决问题的答案，正统经济学再次受到严峻的挑战．与此同时，行为经济学，以人类的行为作为基本研究对象的经济理论，正逐步发展起来．本文将介绍行为经济学的产生和发展、主要理论观点以及一些行为分析对中国社会经济发展的启示．
