《孔雀》开屏的启示——对顾长卫获奖影片的文化解读

《孔雀》将温馨情境尽力拼合,运用冷峻的画面震慑观众,叙事沉稳细腻,显示出独到的哲理性意蕴,提高了作品的审美品质。影片将时代伤害过度放大,塑造一群丑陋的中国人形象,图解生活,概念化地塑造人物,缺乏人物与环境的对应性、真实性及逻辑性。     

Learners' eye movements during construction of mechanical kinematic representations from static diagrams

We investigated the influence of numbered arrows on construction of mechanical kinematic representations by using static diagrams. Undergraduate participants viewed a two-stage diagram depicting a flushing cistern (with or without numbered arrows) and answered questions about its function, step-by-step. The arrow group demonstrated greater overall accuracy and made fewer errors on the measure of continuous relations than did the non-arrow group. The arrow group also spent more time looking at components relevant to the operational sequence and had longer first-pass fixation times and shorter saccade lengths. The non-arrow group made more saccades between the two diagrams. Analysis of transition probabilities indicated that both groups viewed components according to their continuous relations. The arrow group followed the numbered arrows whereas the unique pathway of the non-arrow group was to compare the two diagrams. These findings indicate that numbered arrows provide perceptual information but also facilitate cognitive processing.     

Learning from Animated Concept Maps with Concurrent Audio Narration

An animated concept map is a presentation of a network diagram in which nodes and links are sequentially added or modified. An experiment compared learning from animated concept maps and text by randomly assigning 133 undergraduates to study 1 of 4 narrated animations presenting semantically equivalent information accompanied by identical audio narration. Two of the animations presented text; one with concurrent audio and another with delayed audio. Two of the animations presented concept maps; one in black and white and the other with nodes colored to represent semantic relatedness. The concept map groups outperformed the text groups on free recall (p < .05). The black-and-white concept map group outperformed the text groups on a multiple-choice knowledge test (p < .05). No advantages were statistically detected for color enhancements of the animated map. The results indicate that verbal information can be effectively communicated by learner-paced animated concept maps accompanied by audio narrations.

Phase Diagram of the System KCl-CsBr-CaBr_2

1 IntroductionWith the develOPment of the molten salt fuel cell,the use of the phase diagram becomes more and moreextensive. A great help will be gained by using acomputer to predict the relative Parts of the Phasediagram because it is quite difficult for many Phasediagrams tO be determined. The Phase diagram ofCsBr-CaBrZ was Predicted which is the complexcompoUnd-forming system[']. This comPOund has notbeen reported up tO now in lit~.
