国民"健商"培育与学校体育改革

采用文献资料、信息查询等方法,对“健商”这一新概念的内涵、国民“健商”基本状况及提高国民“健商”的方法作了尝试性的研究与探讨。认为,“健商”是一种新健康文化概念;提高国民“健商”应更新学校体育基本理念,改革体育课程,加强学校体育环境的建设,加强学校、社会、家庭一体化建设,注重体育教师素养的提高。

山区高校学生作为一个特殊的消费群体,有着不同于其他消费群体之处,如:他们的消费结构不合理,财商不成熟,理财能力差,攀比心理强,交往消费过高,恋爱支出过度等等,背景比较复杂。     

赋范空间中逐段仿射不等式系统的误差界

文章通过商空间理论,证明了无穷维赋范空间中逐段仿射不等式系统必定存在局部差界,并给出了逐段仿射不等式系统存在整体误差界的一个充要条件。     

译前准备对交替传译质量的影响

该文为一篇口译实践报告,笔者通过参加以色列专家宁夏行——农牧组的翻译工作,学到很多关于农业方面的知识,尤其是节水灌溉、有机农业、以及设施农业。同时也充分认识到,要做好口译工作需要充分的译前准备以及适当的临场应变策略。在本篇报告中,笔者试图通过分析其在此次工作当中的翻译实例,说明充分的译前准备对翻译的质量有积极影响,而译前准备不足对翻译质量有消极影响,并向读者说明如何科学合理地进行译前准备工作,以及在准备不充分的时候如何快速地进行临场应变。并且通过案例分析,让读者更加直观地理解译前准备的作用,以及临场应变能力的重要性。希望本篇实践报告能对译员进行此类翻译活动有一定的帮助。     

偏序半群的偏序同态和商序同态的若干重要性质

通过偏序半群的同余、半格同余和自然序半格同余,对偏序半群的偏序同态与商序同态的性质进行了刻画,得到了一些重要结论.     

关于增广商群结构问题的讨论

对任意有限群G的整群环ZG,设Δn(G)是ZG的n次增广理想,记Qn(G)=Δn(G)/Δn 1(G)为G的增广商群.本文给出了Qn(G)的一组与G的Sylowp-子群相关的生成元,并且在利用这组生成元和已有结果的基础上对二面体群D2tk(k奇)之增广商群Qn(D2tk)的结构进行了讨论,证明了Qn(D2tk)Qn(D2t).     

交传同传，哪个更难？——浅较会议口译中的交传和同传

会议口译包括交替传译和同声传译两种主要形式,一般的看法是同传比交传的难度要大。本文从口译的过程分析了两者的一弛陛,之后分别列举了两者相较对方更难的地方,指出交传同传因为各自的爿争．董对译员的不同能力有不同要求,不能简单说l哪一个更难。     

基于分形方法估算部分商为a或b的连分数集维数

连分数的展开式具有结构上的自相似性,部分商满足一定条件的连分数构成的集合是分形集,通过构造迭代映射的方法估算其Hausdorff维数.

辅助生殖技术学龄前单双胎子代的认知发展存在差异么?(英文)简

Objective： To explore whether there exist differences in cognitive development between singletons and twins born after in vitro fertilization （IVF） or intracytoplasmic sperm injection （ICSI）. Methods： A total of 566 children were recruited for the study, including 388 children （singletons, n=175; twins, n=213） born after IVF and 178 children （singletons, n=87; twins, n=91 ） born after ICSI. The cognitive development was assessed using the Chinese-Wechsler Intelligence Scale for Children （C-WISC）. Results： For all pre-term offspring, all the intelligence quotient （IQ） items between singletons and twins showed no significant differences no matter if they were born after IVF or ICSI. There was a significant difference in the cognitive development of IVF-conceived full-term singletons and twins. The twins born after IVF obtained significantly lower scores than the singletons in verbal IQ （containing information, picture ＆ vocabulary, arithmetic, picture completion, comprehension, and language）, performance IQ （containing maze, visual analysis, object assembly, and performance）, and full scale IQ （P〈0.05）. The cognitive development of full-term sin- gletons and twins born after ICSI did not show any significant differences. There was no significant difference between the parents of the singletons and twins in their characteristics where data were collected, including the age of the mothers, the current employment status, the educational backgrounds, and areas of residence. There were also no consistent differences in the duration of pregnancy, sex composition of the children, age, and height between sin- gletons and twins at the time of our study although there existed significant differences between the two groups in the sex composition of the full-term children born after ICSI （P〈0.05）. Conclusions： Compared to the full-term singletons born after IVF, the full-term twins have lower cognitive development. The cognitive development of full-term singletons and twins born after ICSI did not show any significant differences. For all pre-term offspring, singletons and twins born after IVF or ICSI, the results of the cognitive development showed no significant differences.
