Linked lives: stability and change in maternal circumstances and trajectories of antisocial behavior in children

Drawing on the notion of linked lives, this study examined the effects of stability and change in maternal circumstance on developmental trajectories of antisocial behavior in children 4 to 7 years of age. Using data from a national sample of young mothers and growth curve analysis, the study demonstrated that early maternal circumstances influences early antisocial behavior, whereas stability and change in these circumstances both exacerbate and ameliorate behavior problems. Of particular note, meaningful escape from poverty attenuates antisocial behavior whereas persistence in poverty or long-term movement into poverty intensifies such problems. These findings highlight the importance of structural context for parenting practices and the need to consider child development in light of dynamic and changing life-course fortunes of parents.     

智能的体操 教育的手段

文化发展的历史有力地证明,人类对象棋的兴趣不断提高。近几个世纪以来它吸引了成千上万的爱好者。有关象棋的书有上万种,各国出版的杂志也不下千种。世界各地这种古老娱乐的爱好者们都以浓厚的兴趣注视着每场比赛。许多杰出的政治家、军事统帅、作家、音乐家、学者认为下象棋不仅是休息和消遣,而且是一种独特的智能体操,也是培养性格的有效方法。苏联学校利用象棋的大量实践,对其他国家的教育家和体育教练工作经验的分析,充分证实了利用象棋来培养、教育各种年龄的学生,开发他们的智力的巨大可能性。因此,毫无     

职业教育——哲学和理论的阐述

引言 职业教育理论只是最近才发展为一门学科,它正如人们所称的处于类似青春期的阶段(Crites,1981)。然而,最近几年已经有了不少进展。如果我们要在学校中推行一种有效的职业教育计划,就必须对职业教育理论有所了解。 在考察职业教育理论中,我们必须考虑到某些限制因素。首先,不同理论的许多假设是试验性的;第二,现存的研究中许多是依据对中层男性白人的研究资料(Herr,1970);第三,职业发展理论不能作为所有职业教育和咨询计划的一般发展理论之基础(Tolbert,1980)。     

Hybrid heuristic and mathematical programming in oil pipelines networks： Use of immigrants

We solve the problem of petroleum products distribution through oil pipelines networks. This problem is modelled and solved using two techniques: A heuristic method like a multiobjective evolutionary algorithm and Mathematical Programming. In the multiobjective evolutionary algorithm, several objective functions are defined to express the goals of the solutions as well as the preferences among them. Some constraints are included as hard objective functions and some are evaluated through a …     

桑格格的青春年代(A)

1 我出生的时候据说是哭得一边一凼眼泪水,跟到跟到地流,接生的医生说:人家都是干嚎,这个娃娃怪,水分恁个多!不哭了,　 在秤盘上,我做出了人生的第一个动作:将大拇指塞到嘴头,吮得“啪啪啪”地响。 单位房子紧张,我妈睡在废弃的锅炉房里,幸福地期待着我的到来。白天还有燕儿来绕梁,说是个好预兆,只是到了晚上门关不严,风吹过,门哒得“咵咵”响惊了她,我二舅说,枪可以闭邪,就把他的配枪放在 我 妈 的 枕 头 下 来 。幸 好 没走 火呦!这与我后来宝里宝器的性格恐怕有直接的关系。 你根本不知道,我是天上派来的天女,我有很多兵,我把他们都埋在…     

基于红外图像的绝缘子高温区域特征研究

绝缘子故障会引起表面温度的上升,造成局部区域高温。因此,准确识别绝缘子的高温区域是故障检测的有效途径。本文提出了基于灰度共生矩阵的绝缘子高温特征提取方法。红外图像经过图像分割后,提取纹理特征,选取能量、熵、惯性矩和相关性作为特征值。试验结果验证该方法准确性高,可为绝缘子高温区域的识别提供参考。
