“He Survives Everything”: A Latency-Aged Child with Play Disruption in the Face of Trauma and Early Object Loss

It is hypothesized that trauma and early object loss result in the arrest of the normal and healthy progression of a child's development and also disrupts a child's capacity to engage in symbolic play. In therapy, over time, with a constant object, a latency-aged child was able to re-enact early trauma and loss, make substantial gains in development, and begin to play in a symbolic and expressive way.

Marital Conflict,Ineffective Parenting,and Children's and Adolescents' Maladjustment

Data from the 1988 National Survey on Families and Households were analyzed to examine the associations among marital conflict, ineffective parenting, and children's and adolescents' maladjustment. Parents' use of harsh discipline and low parental involvement helped explain the connection between marital conflict and children's maladjustment in children aged 2 through 11. Parent‐child conflict was measured only in families with a target teenager and also was a significant mediator. Although ineffective parenting explained part of the association between marital conflict and children's maladjustment, independent effects of marital conflict remained in families with target children aged 2 through 11 (but not for families with a teenager). With a few exceptions, this pattern of findings was consistent for mothers' and fathers' reports, for daughters and sons, for families with various ethnic backgrounds, and for families living in and out of poverty.     

价值重估的尺度──论五四人学思想及其现代意义

五四新文化运动是一场价值重估运动。五四新文化运动重估一切价值的尺度是什么？在这个问题上，中国学界一直缺乏必要的认识，因而导致了对新文化运动阐释的许多混乱。其实，五四新文化先驱者们的实践早已证明：人，是五四新文化运动的基本出发点和最终目的，也是重估一切价值的最高价值尺度。五四新文化运动的先驱者们用以比较和判断东西方文明优劣的价值标准不是别的，是个人的独立、自由和权利。这是新文化运动的基本态度，因此也决定了新文化运动的根本性质。正因为这样，新文化运动才在中国文化史上具有了划时代的意义。     

The Impact of Taking Parental Leave on Fathers’ Participation In Childcare And Relationships With Children: Lessons from Sweden

In Sweden, government-mandated paid parental leave has been available to both mothers and fathers since 1974. By 2006, each parent had two non-transferable leave months and nine additional months to share. From the beginning, parental leave was presented as a policy designed to promote gender equality, with women and men having equal opportunities and responsibilities to contribute economically to the family and care for children. Sweden thus provides a unique setting to explore whether social policy can be an important instrument for changing the gender contract. Analysing survey data from 356 fathers working in large private companies, we found that the amount of parental leave days taken had positive effects on several aspects of fathers’ participation in childcare and on their satisfaction with contact with children, controlling for other factors contributing to fathers’ participation in childcare. Our findings suggest that the full potential of Sweden's parental leave policy for degendering the division of labour for childcare will not likely be met until fathers are strongly encouraged by social policy to take a more equal portion of parental leave.     

卧式椭圆轨迹振动筛的自定中心问题研究

当振动筛筛箱各点作长轴平行于筛面的椭圆轨迹运动时,这种振动筛的胶带轮不可能只作定轴转动(即自定中心)。如果恰当地选择胶带轮几何中心的偏心值,胶带轮的摆动幅度将减小,因此,胶带的工作情况仍将得到改善。     

New imperfect rankings models for ranked set sampling

Ranked set sampling is a sampling approach that leads to improved statistical inference in situations where the units to be sampled can be ranked relative to each other prior to formal measurement. This ranking may be done either by subjective judgment or according to an auxiliary variable, and it need not be completely accurate. In fact, results in the literature have shown that no matter how poor the quality of the ranking, procedures based on ranked set sampling tend to be at least as efficient as procedures based on simple random sampling. However, efforts to quantify the gains in efficiency for ranked set sampling procedures have been hampered by a shortage of available models for imperfect rankings. In this paper, we introduce a new class of models for imperfect rankings, and we provide a rigorous proof that essentially any reasonable model for imperfect rankings is a limit of models in this class. We then describe a specific, easily applied method for selecting an appropriate imperfect rankings model from the class.
