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.

企业技术竞争力评价指标体系研究：构建、测评与结论

在分析企业技术竞争力内涵的基础上构建了企业技术竞争力评价指标体系,尝试利用层次分析法对该指标体系进行测评,通过构造判断矩阵并伴随一致性检验,得到了各指标体系的总排序结果。研究表明,从准则层的3项目标来看,企业的技术创新竞争力对总目标的影响权重占有绝对优势;从指标层的29项评价指标来看,影响最大的10项指标在对总目标的影响权重值中占大部分比例,这些指标是提升企业技术竞争力水平的关键所在。
