Same beginnings, different stories: a comparison of American and Chinese children's narratives   总被引：3，自引：0，他引：3  

Wang Q  Leichtman MD 《Child development》2000,71(5):1329-1346

This study examined social, emotional, and cognitive characteristics of American and Chinese children's narratives. Twenty-four American and 26 Chinese 6-year-old children participated. Each child was interviewed individually twice with a 1-week delay interval. During the two interviews, children were asked to tell 11 stories prompted by pictures and standard verbal leads and to recount 7 emotional memories. Content analyses were performed on children's stories and memories. In line with predictions, findings indicated that compared with American children, Chinese children showed greater orientation toward social engagement, greater concern with moral correctness, greater concern with authority, a less autonomous orientation, more expressions of emotions, and more situational details in both their stories and memories. A few gender differences were found. Findings are discussed in terms of different value systems and early socialization practices in these two cultures.  相似文献

Optofluidic planar reactors for photocatalytic water treatment using solar energy     

Lei L  Wang N  Zhang XM  Tai Q  Tsai DP  Chan HL 《Biomicrofluidics》2010,4(4):43004

Optofluidics may hold the key to greater success of photocatalytic water treatment. This is evidenced by our findings in this paper that the planar microfluidic reactor can overcome the limitations of mass transfer and photon transfer in the previous photocatalytic reactors and improve the photoreaction efficiency by more than 100 times. The microreactor has a planar chamber (5 cm×1.8 cm×100 μm) enclosed by two TiO(2)-coated glass slides as the top cover and bottom substrate and a microstructured UV-cured NOA81 layer as the sealant and flow input∕output. In experiment, the microreactor achieves 30% degradation of 3 ml 3×10(-5)M methylene blue within 5 min and shows a reaction rate constant two orders higher than the bulk reactor. Under optimized conditions, a reaction rate of 8% s(-1) is achieved under solar irradiation. The average apparent quantum efficiency is found to be only 0.25%, but the effective apparent quantum efficiency reaches as high as 25%. Optofluidic reactors inherit the merits of microfluidics, such as large surface∕volume ratio, easy flow control, and rapid fabrication and offer a promising prospect for large-volume photocatalytic water treatment.  相似文献   

A diagnostic assessment for introductory molecular and cell biology     

Shi J  Wood WB  Martin JM  Guild NA  Vicens Q  Knight JK 《CBE life sciences education》2010,9(4):453-461

We have developed and validated a tool for assessing understanding of a selection of fundamental concepts and basic knowledge in undergraduate introductory molecular and cell biology, focusing on areas in which students often have misconceptions. This multiple-choice Introductory Molecular and Cell Biology Assessment (IMCA) instrument is designed for use as a pre- and posttest to measure student learning gains. To develop the assessment, we first worked with faculty to create a set of learning goals that targeted important concepts in the field and seemed likely to be emphasized by most instructors teaching these subjects. We interviewed students using open-ended questions to identify commonly held misconceptions, formulated multiple-choice questions that included these ideas as distracters, and reinterviewed students to establish validity of the instrument. The assessment was then evaluated by 25 biology experts and modified based on their suggestions. The complete revised assessment was administered to more than 1300 students at three institutions. Analysis of statistical parameters including item difficulty, item discrimination, and reliability provides evidence that the IMCA is a valid and reliable instrument with several potential uses in gauging student learning of key concepts in molecular and cell biology.  相似文献

柳絮何以称杨花     

大头博士 《语文世界(高中版)》2002,(2)

《梅雨潭》一文。有这样一段叙述：“那溅着 的水花，微雨似的纷纷落着。据说，这就是梅雨潭 之所以得名、 但我觉得像杨花格外确切些－轻 风起来时，点点随风飘散，那更像是杨花了”这 里的“杨花”，系指柳絮。 柳絮为什么称杨花呢？原来，柳树在古代是一 种吉祥之物。友人回归，主人往往要折一支柳枝相赠，以示挽留之意。因为“柳”谐音“留”。到了公元６０５年，隋炀帝下令开凿运河，号召民众在河岸植柳，每种活一棵者，奖细绢一匹。于是百姓争植，岸柳成阴。隋炀帝为了显示他的威风，就举行了他亲自植柳的仪式，并挥御笔书赠柳树姓杨…  相似文献
