营运客车追尾碰撞速度分析

建立某6127型营运客车和某重型货车的追尾碰撞模型,将碰撞速度分别设置为30 Km/h、40 Km/h和50 Km/h,在LS-DYNA软件中分别进行了有限元仿真,通过后排座椅的位移量、客车质心的加速度和假人颈部损伤值三项指标的对比分析,结果表明在40 Km/h的碰撞速度下,车身结构的变形与实际的碰撞事故较为接近,其它两项评价指标也较为合理。     

类碰撞问题的分析

碰撞模型的特征： （1）系统动量守恒;（2）系统动能不增;（3）情景可行．如甲物体追乙物体并发生碰撞,碰前甲的速度必须大于乙的速度;碰后甲的速度比碰前速度小,而乙的速度比碰前速度大;碰后甲物体的速度小于或等于乙物体的速度或甲反向运动．     

从国际劳工标准看我国农民工权益保护

国际劳工标准是国际劳工组织保护劳动者权益的基本标准。在农民工权利保障缺乏的背景下,用“核心国际劳工标准”保护农民工权益有着特殊的意义。我国应该按照国际劳工标准结合我国的具体国情,积极有效的维护农民工的平等就业权,建立健全农民工的社会保障制度,积极促使农民工组成工会组织,保护农民工的合法权益。

过分的保护也是一种伤害

一个幼儿不小心跌倒了,作为母亲来说的你会怎么办？从母性出发,我们会情不自禁地赶紧扶起哇哇大哭的孩子,因为他太小了,需要我们精心的照顾和保护。但理智告诉我们,要让孩子自己站起来,要学会坚强,过分的保护对孩子也是一种伤害。苗苗（化名）是一位可怜的小姑娘。     

碰撞问题分析

碰撞问题综合性强,几乎涉及力学的全部内容,在中学物理教学中是难点同时也是重点.在高考和自主招生考试中与碰撞相关的题目频频出现,但有相当一部分学生对碰撞的物理实质比较模糊,导致此类题目错误率比较高.因此,有必要对碰撞问题做以详细分析.1碰撞的定义在物理学中,将具有相对速度的物体,发生相互作用的现象称为碰撞.碰撞现象到处可...

Chinese and American English Teaching Methods in Contrast

China’s traditional teaching methods, Grammar-Translation Methods, can not satisfy modern English teaching anymore. Since English transferred into China as a foreign language, the Grammar-Translation Methods was the only teaching method. Nowadays, China’s English teaching methods have been greatly promoted and improved; however, the Grammar-Translation Methods still over weight the others.

美国中等职业教育教师专业标准及其启示

界定了美国中等生涯与技术教育（CTE）教师专业标准的内涵,介绍了美国初级、优秀中等CTE教师专业标准的结构、内容特征和开发及运用实践方式,提出了其对我国中职教师标准建设的启示：形成多层次的中职教师专业标准体系;科学制定中职教师专业标准框架;切实保障专业发展的科学评价质量。     

Help-Seeking Experiences and Attitudes among African American, Asian American, and European American College Students

The study examined African American, Asian American, and European American college students’ previous direct and indirect experiences of seeking professional psychological services and related attitudes. Survey data were collected from 254 European American, 182 African American and 82 Asian American college students. Results revealed that fewer African American and Asian American college students had sought professional psychological services, knew someone who had sought psychological services, and knew a close person who was diagnosed with a psychological disorder, relative to European American students. Furthermore, African American and Asian American participants showed less favorable attitudes on a variety of help-seeking attitudes, compared to the European American group.

Consequences of learning about historical racism among European American and African American children

Knowledge about racism is a critical component of educational curricula and contemporary race relations. To examine children's responses to learning about racism, European American (Study 1; N= 48) and African American (Study 2; N= 69) elementary-aged children (ages 6-11) received history lessons that included information about racism experienced by African Americans (racism condition), or otherwise identical lessons that omitted this information (control condition). Children's racial attitudes and cognitive and affective responses to the lessons were assessed. Among European American children, racism condition participants showed less biased attitudes toward African Americans than control condition participants. Among African American children, attitudes did not vary by condition. Children in the two conditions showed several different cognitive and affective responses to the lessons.     

Cultural differences in Chinese American and European American children's drawing skills over time

Parents and early childhood teachers in Chinese societies and the United States have had dissimilar views about appropriate art instruction for young children. The Chinese view is that creativity will emerge after children have been taught essential drawing skills. The American view has been that children's drawing skills emerge naturally and that directive teaching will stifle children's creativity. Forty second-generation Chinese American and 40 European American young children participated in this longitudinal study at ages 5, 7, and 9 to explore possible cultural differences in and antecedents of their drawing skills and creativity. Chinese American children's person drawings were more mature and creative and their parents reported more formal ways of fostering creativity as compared to their European American counterparts. Correlations showed that children who had more opportunities to draw and who received more guidance in drawing were more advanced in their drawing. For Chinese Americans, fathers’ personal art attitudes and children's Time 1 drawing skills predicted 53% of the variance in children's drawing scores four years later.
