Chinese and Canadian Children's Evaluations of Lying and Truth Telling: Similarities and Dfferences in the Context of pro-and Antisocial Behaviors     

Kang Lee  Catherine Ann Cameron  Fen Xu  Genyao Fu And  Julie Board 《Child development》1997,68(5):924-934

The present study compared Chinese and Canadian children's moral evaluations of lie and truth telling in situations involving pro- and antisocial behaviors. Seven-, 9-, and 11-year-old Chinese and canadian children were presented 4 brief stories. Two stories involved a child who intentionally carried out a good deed, and the other2 stories involved a child who intentionally carried out a bad deed. When story characters were questioned by a teacher as to who had committed the deed, they either lied or told the truth. Children were asked to evaluate the story characters' deeds and their verbal statements. Overall, Chinese children rated truth telling less positively and lie telling more positively in prosocial settings than Canadian children, indicating that the emphasis on self-effacement and modesty in Chinese culture overrides Chinese children's evaluations of lying in some situations. Both Chinese and canadian children rated trugh telling positively and lie telling negatively in antisocial situations, reflecting the emphasis in both cultures on the distinction between misdeed and truth/lie telling. The findings of the present study suggest that, in the realm of lying and truth telling, a close relation between sociocultural practices and moral judgment exists. Specific social and cultural norms have an impact on children's developing moral judgments, which in turn, are modified by age and experience in a particular culture.  相似文献

对话教育及其实施策略     

沈桂兰 《教育科学论坛》2005,(7):9-12

对话教育在本质上,是以人为本的教育。它把学生作为一个完整的人,使学生学会自尊、自信、善于合作并使学生学会以积极的姿态展现自我、发现自我、创造自我。由于认识上的局限和教师自身的种种原因,我们在观念认识和实施过程中往往误入歧途。针对这些问题,本文旨在从对话教育的概念、要素及其关系、实施误区及实施策略展开讨论和研究。  相似文献   

完善企业境外投资的财政金融政策支持体系     

亢玲莉 《山西师大学报(社会科学版)》2005,32(5):34-36

随着经济全球化的发展,企业跨国投资的步伐愈来愈快。在跨国投资过程中,企业也会面临各种困难与风险。发达国家在企业跨国投资过程中,运用税收、信贷、保险等金融手段对境外投资给予促进和必要的制约,从而分散企业的经营风险。我国企业在跨国投资过程中,也应该借鉴国际经验,建立和完善企业境外投资的税收制度,加大企业信贷优惠政策扶持力度,完善企业境外投资保险制度、企业境外投资准备金制度、中小企业境外投资的融资政策等,以分散企业的经营风险。  相似文献   

Home: A Feeling Rooted in the Heart     

Weimin Mo  Wenju Shen 《Children‘s Literature in Education》2007,38(3):173-185

Culturally diverse as they are, Asian-American children and youth share quite a few features among themselves. Most of them are children of foreign-born parents who came to America during the post-1965 immigration waves. As they grow up in culturally isolated environment, they are often faced with identity crisis. The society’s racial exclusion makes them feel like “forever foreigners,” while at home or community their American frame of reference is often in conflict with parents’ traditional values. As a result, they develop a flexible concept of identification. In fact, they are a part of but also apart from the American mainstream culture.  相似文献

Tandem Biocatalysis by CotA-TJ102@UIO-66-NH2 and Novozym 435 for Highly Selective Transformation of HMF into FDCA     

Chang  Xin  Zhang  Chengyu  Gao  Lan  Liu  Xiao  You  Shengping  Qi  Wei  Wang  Kang  Guo  Xin  Su  Rongxin  Lu  Han  He  Zhimin 《天津大学学报(英文版)》2019,25(5):488-496

2,5-Furandicarboxylic acid(FDCA) is a potential biorenewable chemical for applications including plastics, polyamides, drugs, etc. The selective biosynthesis of FDCA from 5-hydroxymethylfurfural(HMF) by a specific enzyme poses a great challenge. In this study, we reported an efficient strategy to produce FDCA from HMF by the tandem biocatalysis of laccase(Cot A-TJ102@UIO-66-NH_2) and Novozym 435. For the first step, a nanoparticle metal–organic framework was synthesized as a carrier to immobilize Cot A-TJ102@UIO-66-NH_2, which was assigned for the production of 5-formyl-2-furancarboxylic acid(FFCA) and featured an enzyme loading of 255.54 mg/g, specific activity of 135.90 U/mg, and solid loading ratio of 99.65%. Under optimal conditions, an ideal FFCA yield of 98.5% was achieved, and the Cot A-TJ102@UIO-66-NH_2 presented a high recycling capacity after 10 cycles. For the second step, Novozym 435 was applied for the further conversion of FFCA into FDCA, presenting a high FDCA yield of 95.5% under the optimized conditions. Novozym 435 also exhibited a high recyclability after eight cycles. As a result, the tandem biocatalysis strategy provided a 94.2% FDCA yield from HMF, indicating its excellence as a method for FDCA production.  相似文献
