班主任如何对学生进行青春期教育

青春期是学生性发育和性心理趋向成熟的特殊时期.在这个时期,班主任对学生进行青春期的教育应立足于学校现有的教育环境,从四项教育原则入手,达到三项基本技能.     

Child maltreatment deaths in the U.S. National Child Death Review Case Reporting System

Comprehensive reviews of child death are increasingly conducted throughout the world, although limited information is available about how this information is systematically used to prevent future deaths. To address this need, we used cases from 2005 to 2009 in the U.S. National Child Death Review Case Reporting System to compare child and offender characteristics and to link that information with actions taken or recommended by review teams. Child, caretaker, and offender characteristics, and outcomes were compared to team responses, and findings were compared to published case series. Among 49,947 child deaths from 23 states entered into the Case Reporting System during the study period, there were 2,285 cases in which child maltreatment caused or contributed to fatality. Over one-half had neglect identified as the maltreatment, and 30% had abusive head trauma. Several child and offender characteristics were associated with specific maltreatment subtypes, and child death review teams recommended and/or planned several activities in their communities. Case characteristics were similar to those published in other reports of child maltreatment deaths. Teams implemented 109 actions or strategies after their review, and we found that aggregating information from child death reviews offers important insights into understanding and preventing future deaths. The National Child Death Review Case Reporting System contains information about a large population which confirms and expands our knowledge about child maltreatment deaths and which can be used by communities for future action.     

浅谈班主任工作体会

从中职学校班主任工作遇到的实际问题着手,对班主任工作的方法和理念进行了分析。     

螺栓预紧力对发动机气缸盖疲劳特性的影响

发动机气缸盖是较易发生疲劳破坏的发动机零件之一,其机械疲劳强度与螺栓预紧力之间存在关系。利用Solidworks建立气缸的简化模型,导入Workbench中进行静力学分析：在Workbench中建立两个不同的载荷环境,利用组合求解功能对螺栓预紧力和气缸盖受到气缸内气体的最高爆发压力进行线性组合,完成非比例载荷的疲劳寿命计算,得到不同螺栓预紧力下的气缸盖疲劳寿命曲线,由此获知螺栓预紧力和气缸盖疲劳寿命之间的关系,这为合理选择螺栓预紧力提供了依据。     

电表改装与校准

电表在测量中有广泛的应用,因此如何了解电表和使用电表就显得十分重要。电流计是用来测量微小电流的,允许通过的电流很小,本文用它来扩大量程。     

《红楼梦》中癞僧、跛道度人考

癞僧、跛道在《红楼梦》中是一对不起眼的人物。本文通过对其在小说前80回中出场及其活动的分析,发现在作者笔下他们是有各自分工的———癞僧度女子,跛道度男子,“石头”(通灵宝玉)只与癞僧发生关系,是小说的一大章法;从而考证“佚稿”中贾宝玉最终出家是由跛道引度,而送“石头”归青埂峰的是癞僧。     

Ethnic group differences in early head start parents’ parenting beliefs and practices and links to children's early cognitive development

Data from the Early Head Start Research and Evaluation study were used to examine the extent to which several factors mediate between- and within-ethnic-group differences in parenting beliefs and behaviors, and children's early cognitive development (analysis sample of 1198 families). The findings indicate that Hispanic-, European-, and African-Americans differ significantly in their parenting beliefs and behaviors. Children also evidence significant ethnic group differences in 24-month cognitive development; these differences were fully accounted for by controlling for maternal cognitive skills, as measured by lexical knowledge. In comparison, maternal parenting behaviors were only a partial mediator of ethnic group differences in children's cognitive development. Structural equation modeling was used to examine, within each ethnic group, the extent to which measured parenting beliefs and behaviors mediate the effect of maternal cognitive skills on children's early cognitive development. Analyses show that the mediated path from maternal cognitive skills to child cognitive development, via “mainstream” parenting beliefs and behaviors, was stronger for European-American families than for Hispanic- and African-American families. The policy implications of increasing the schooling-related cognitive skills of low-educated parents are discussed.     

怎样的班主任才是优秀的小学班主任——对四位乡村小学班主任的访谈

班级是学校对学生进行教育和教学工作的基层单位，班主任是班级管理的舵手。而小学班主任是人在启蒙阶段最关键的雕塑师，他（她）与学生之间的交往可以达到彼此间内在心灵的最微妙的接触。本研究中选取四位乡村小学班主任作为访谈对象，就她们的工作成就感与困惑之所在作些片断性的展示，并从中提出自己的反思和感悟。

农村精英及其社会影响初探

农村精英是指农村中那些出类拔萃，精明强干的人。中国社会主义初级阶段农村需要精英。精英是农村经济发展的带头人，政治稳定的中坚，精神文明的传播者。中国农村，尤其是西部农村需要培育更多的经济大户精英。
