The state intervenes in the battle of the sexes: Causal effects of paternity leave

Do family policies influence attitudes and behavior or are they merely reflections of pre-existing attitudes? We consider the implementation of the Norwegian daddy quota, 4 weeks of parental leave reserved for the father, as a natural experiment, and examine the long-run causal effects on attitudes toward gender equality, on conflicts and sharing of household labor, and on support for public childcare. We find that respondents who had their last born child just after the reform report an 11% lower level of conflicts over household division of labor and that they are 50% more likely to equally divide the task of washing clothes than respondents who had their last child just before the reform.

The Presentation of Avatars in Second Life: Self and Interaction in Social Virtual Spaces

What do interactions in virtual spaces suggest about everyday life in the digital age? How do interactions in virtual spaces shape everyday life in the digital age? Guided by hypermodern theory, I conduct participant observation in the social virtual world Second Life to provide tentative answers to those questions. I suggest that Second Life is both a social psychological playground where participants enjoy individualistic fantasies and a virtual community where they collaborate on collective projects. When people define the virtual as real, it is real in its consequences. Accordingly, social virtual spaces such as Second Life offer sociologists unique opportunities for research, education, intervention, and hence the development of a virtual imagination.     

Identity Management of the Dead: Contests in the Construction of Murdered Children

Presenting data gathered from fieldwork and ethnographic interviews with families of homicide victims, this study explores “postmortem identity‐contests” faced by families who have experienced the homicide of a child or other family member. Interview data from families on their interaction with police, funeral home directors, and other institutional officials suggest that the construction of postmortem identities is commonly a process of contestation filled with competing identity‐claims. The findings reveal that as families resist “oppressive othering” by the state and other institutional actors, they develop various accounts and strategies in “selfing” and sanctifying the identity of the dead.

聚合物/表面活性剂二元复合驱研究进展

从聚合物/表面活性剂二元体系的特点出发，综述了聚/表聚/表二元复合体系的实验室研究现状以及在胜利油田孤东七区54-61进行的矿场试验情况。聚/表二元复合驱是在聚/表/碱三元复合驱的基础上去掉碱所形成的低浓度的驱油体系，可以最大限度地发挥聚合物的粘度和弹性，减少乳化液处理带来的负面影响，减弱由于碱的存在引起的地层以及井筒结垢的现象。通过国内外研究结果分析表明，聚/表二元复合体系提高原油采收率幅度在20%左右；矿场试验取得了较好的效果。聚/表二元复合体系可以克服三元体系的缺点，作为一项新的驱油方法具有宽阔的发展空间。
