Creating Stepfamilies: Integrating Children Into the Study of Union Formation

As a result of the growth in out‐of‐wedlock childbearing and union instability, adults contemplating forming a new union are often already parents. This article examines the role of children in stepfamily formation, both coresident and not, using the 2,594 respondents in the National Survey of Families and Households who were not living with a partner in 1987/1988. We consider children of the respondent and of the partner, which allows us to examine the determinants of entering a stepfamily. We found that being a coresident father dramatically increases forming a union with a woman with children. Women’s coresidential children reduce women’s odds of forming unions with men who do not have children and increase them for unions with men who do.     

Threshold decisions: how social workers prioritize referrals of child concern

This paper examines local authority social workers' decision‐making when considering referrals of children, where the concerns are on the margin of child protection procedures. In doing so, it describes the findings of a qualitative research study undertaken in the policy context of attempts to ‘refocus’ social work practice in the late 1990s and early twenty‐first century. Data collection involved interviews with social workers and parents in 23 cases. Conclusions are that referrals were evaluated on the basis of five key factors, specificity, severity, risk, parental accountability and corroboration, the use of which determined whether an initial assessment or an investigation of alleged abuse took place. The analysis builds on previous work in the child protection field, but demonstrates how the application of these factors differs between cases of child concern and cases of child protection. Policy implications concern the complexity of decision‐making in the uncertain context of limited referral information and it is proposed that the simplistic notion of a continuum of abuse is now outdated.

日据至光复初期台湾博物馆管窥

日据至光复初期台湾的主要博物馆有4个,其中首推台湾总督博物馆,次为台中教育博物馆,台南教育博物馆,嘉义通俗博物馆。台湾总督博物馆,是台湾最早的博物馆,历史可追溯到1899年;1945年台湾光复,改称为台湾省博物馆。此外,当时台湾的部分院校和科研机构,亦设置有博物馆、植物园及小型的陈列馆或标本室。     

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.     

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.
