Comparison of methods for analyzing binary repeated measures data: A simulation-based study (comparison of methods for binary repeated measures)

In this study, some methods suggested for binary repeated measures, namely, Weighted Least Squares (WLS), Generalized Estimating Equations (GEE), and Generalized Linear Mixed Models (GLMM) are compared with respect to power, type 1 error, and properties of estimates. The results indicate that with adequate sample size, no missing data, the only covariate being time effect, and a relatively limited number of time points, the WLS method performs well. The GEE approach performs well only for large sample sizes. The GLMM method is satisfactory with respect to type I error, but its estimates have poorer properties than the other methods.     

Cracking the Code—An Approach to Developing Professional Writing Skills

The development of writing skills sufficient to meet the complexities of contemporary social work practice is a growing demand from employers and practice educators. The paper explores current pedagogical debate relating to student support and the development of writing skills and relates this debate to meeting the needs of social work students engaged in practice learning and professional practice. A number of questions are raised about current social work education in England and the needs of students entering from non-traditional academic backgrounds facing the increasingly rigorous demands of professional report writing. The discussion is then grounded in a practice example of staff from a university social work course and education guidance service working together to meet student need in respect of developing writing skills. The development, implementation and evaluation of a university writing skills programme for social work students are explored. The paper concludes by setting out a range of challenges arising from experience of the programme and a consideration of theory, and points to potential ways forward based on a social practice approach to teaching writing skills.     

Those They Leave Behind: Paternal Incarceration and Maternal Instrumental Support

As the American imprisonment rate has risen, researchers have become increasingly concerned about the implications of mass imprisonment for family life. The authors extend this research by examining how paternal incarceration is linked to perceived instrumental support among the mothers of inmates' children. Results from the Fragile Families and Child Wellbeing Study (N = 4,132) suggest that recent, but not current, paternal incarceration is independently associated with less maternal perceived instrumental support and that this association persists after adjusting for a rich set of control variables, including prior perceived instrumental support. For families of recently incarcerated men, incarceration may be a double strike, simultaneously increasing the need for instrumental support while decreasing its availability when incarcerated fathers return to the community.     

1977～2009年人口学CSSCI期刊论文作者统计分析

论文是科研人员从事科学研究产生成果的重要表现形式,作者数量和文献数量之间的关系是遵循科学研究发展的客观规律。通过使用文献计量学的方法,对7种人口学CSSCI期刊自创刊起至2009年的全部论文进行分析,主要发现:(1)7种期刊不同论文数量的作者占作者总人数的概率分布都遵循Lotka定律,新老作者结构合理;(2)7种期刊新增量都显著低于理论最佳值,说明学术研究队伍非常稳定,但是活力不足,容易出现作者老化现象。     

两岸大学生志愿服务动机与激励机制比较研究

20世纪70年代以来,志愿者组织在全球范围兴起并得到发展,逐渐成为现代社会发展的一支活跃力量,在全球掀起了开展志愿服务的热潮。大学生志愿者作为我国志愿服务的重要参与主体,在志愿服务中起到了举足轻重的作用。在两岸和平发展新时期,两岸出现了大交流、大合作、大发展的新局面。作为志愿服务的主力军,两岸大学生志愿服务动机和激励机制的比较,有利于促进两岸大学生志愿服务合作机制的建立。     

Relationship Churning and Parenting Stress Among Mothers and Fathers

Researchers have documented the consequences of relationship instability for parenting stress but have given little attention to within‐partner relationship instability. In this study, the authors used data from the Fragile Families and Child Wellbeing Study (N = 3,544) to estimate the association between within‐partner relationship instability (known as churning or on‐again/off‐again relationships) and parenting stress. First, they found that by the focal child's 5th birthday about 16% of biological parents experience churning. Second, compared to being stably together with or stably separated from the child's other parent, churning is associated with greater parenting stress for both mothers and fathers. Because parenting stress is the same or higher among churners compared to their counterparts who stably separate, this suggests that, more than a change in partner, relationship instability—whether within or across relationships—is tied to parenting stress.     

Pathways of disadvantage: Explaining the relationship between maternal depression and children’s problem behaviors

A large body of literature documents that children of depressed mothers have impaired cognitive, behavioral, and health outcomes throughout the life course, though much less is known about the mechanisms linking maternal depression to children’s outcomes. In this paper, I use data from the Fragile Families and Child Wellbeing Study to estimate and explain the consequences of maternal depression for 5-year-old children’s internalizing and externalizing problem behaviors. Ordinary least squared (OLS) regression models and propensity score models show that children exposed to both chronic and intermittent maternal depression have more problem behaviors than their counterparts with never depressed mothers. Results also show that economic resources and maternal parenting behaviors mediate much of the association between maternal depression and children’s problem behaviors, but that relationships with romantic partners and social support do little to explain this association. This research extends past literature by illuminating some mechanisms through which maternal depression matters for children; by utilizing longitudinal measures of depression; by employing rigorous statistical techniques to lend confidence to the findings; and by using a large, diverse, and non-clinical sample of children most susceptible to maternal depression. Given that early childhood problem behaviors lay a crucial foundation for short- and long-term life trajectories, the social consequences of maternal depression may be far-reaching.

《古兰经》注释学发展史研究

自伊斯兰教先知穆罕默德注释《古兰经》起，《古兰经》注释便逐渐发展成为伊斯兰文化体系中举足轻重的传统学科——主释学（‘ilma1-tafsir）。注释学历经两大时期形成并完善：口耳相传时期——枞先知穆罕默德时期到再传弟子时期；文字记载时期——始于阿拔斯王朝早期，结束期不得而知。注释学的发展以及涌现出的大量学术成果，彰显出历代穆斯林阐释《古兰经》微言大义的学术动态，反映了伊斯兰文化学术的纵深发展。
