当前,世界不同地方的高层建筑蓬勃发展,逐渐成为城市现代化程度的标志之一。建筑的高度越来越高,结构形式上也越来越复杂,已不再是平面布置简单、对称、规则,竖向质量和刚度沿高度均匀分布,而是形成了各种高度超限、竖向和平面不规则的复杂结构。我们可以看到高层建筑在地震灾害中会受到巨大的损失。而地震区建筑结构设防与不设防,震后结果大不一样。想要在地震中减少地震灾害,就要做好工程建设的抗震设计,这样才能真正达到减轻以至避免地震造成的损失。文章依据有关资料和相关实践经验,对高层房屋结构抗震问题进行了相关研究。 相似文献

In this article I react to the thoughts of Hennessey, addressing mainly the student, and Esquivel, addressing mainly the teacher. These authors present complementary, interesting, and consistent pictures of creativity education. Here I comment on a few issues that are less clear and discuss implications of these authors' work for computers in education. I conclude that teachers need to play with ideas about how they might use computers to build a culture that promotes deep, meaningful, and creative learning.Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the authors and do not necessarily reflect the views of the National Science Foundation. 相似文献

科学实验是科学认识的基础,没有科学实验就没有真正意义上的科学。近年来,发展心理学家对传统的研究方法作了创造性的改进,使研究对象有所扩大,研究内容有所拓展,从而对早期教育产生了更加丰富的实用价值。在儿童发展心理学中,实验法与其他方法的综合运用有着广阔的发展空间,但主流的方法依然是实验法。无论是哪一种研究方法,都必须坚持客观性原则。沉浸于后现代主义的相对主义和无政府主义思潮对科学发展和社会实践活动,包括对幼儿教育的发展是有害的。 相似文献

"没有天生的差生,只有有差异的学生"。差生一定程度上是教育本身制造的。"慢生"变为"差生"与教师有极大的关系。使"慢生"的成长速度加快,最关键的是想方设法激发慢生的内在积极性,使他们为自己的"大器晚成"保持自信和勇气。 相似文献

This study on sensitivity and attachment included 55 toddlers and their parents. Samples included children with autism spectrum disorder (ASD), mental retardation, language delay, and typical development. Children were diagnosed at 4 years of age. Two years before diagnosis, attachment was assessed with the Strange Situation procedure, and parental sensitivity and child involvement during free play were assessed with the Emotional Availability Scale. Parents of children with ASD were equally sensitive as parents of children without ASD, but their children showed more attachment disorganization and less child involvement. More sensitive parents had more secure children, but only in the group without ASD. Less severe autistic symptoms in the social domain predicted more attachment security. Autism challenges the validity of attachment theory. 相似文献

As part of a longitudinal study examining sibling and friend relationships in early and middle childhood, relational aggression by 4-year-olds and their interaction partners in semi-structured free play sessions with siblings and friends was examined during sibling sessions involving both same-gender and mixed-gender sibling pairs. Identifiable acts of relational aggression occurred during many of the interactions observed, but there was also a wide range in the amount of relational aggression produced. Both boys and girls used relational aggression with their siblings much more than they did with their friends. Although boys' and girls' relationally aggressive behaviors occurred at similar rates, the form and function of their relational aggression varied depending on the age and gender of their sibling. 相似文献
