抽汲井试井分析数学模型的建立及精确解

根据抽汲井试井工艺过程及其特点,采用已知上一次抽汲结束时的地层压力分布规律建立下一次抽汲数学模型的方法,建立了抽汲井试井分析数学模型,并在Laplace空间求解出了相应的精确解。将这一成果应用于长庆油田之中,结果表明:该理论能描述抽汲井的井底压力瞬变性及抽汲期井底压力变化无规律性的特征,符合实际测试工艺情况,弥补了抽汲井试井这一空白;提高了该类井试井的解释率和解释结果的可信度。同时,利用该理论还可计算抽汲过程中任一时刻的井底压力和关井时刻的井底压力,解决了抽汲井难以计算关井时刻井底压力的问题。     

Gender and social conformity: Do men and women respond differently to social pressure to vote?

In this paper, we re-analyze data from a large-scale field experiment (N = 344,084) on voter turnout in order to determine whether men and women respond differently to social pressure aimed at voter mobilization. To date, there have been mixed results regarding the interaction between a person’s gender and receptivity to social influence. On the whole, our analyses confirm prior findings that social pressure increases voter turnout but uncover little to no evidence of gender differences in receptivity to social pressure cues in the context of political participation.     

The older the bolder: Does relative age among peers influence children’s preference for competition?

Having been relatively old at school tends to have a long lasting positive effect on professional achievement, in particular in competitive environments (sports, politics). We investigate the roots of this pattern and study whether the relative age position of children at school plays a role in shaping their preference for competition. We run a controlled experiment in high schools across two states in Australia. Our participants are students who are the very oldest or very youngest in their classroom. We elicit their preference for competition using the Niederle and Vesterlund (2007) task and find evidence of an effect of relative age. This effect is concentrated on male students. We find no differences in self-confidence, and risk attitudes between relatively old and young students. These results suggest that the observed pattern may come from pure preference for competition.

分段启动压力对宝浪油田驱动压差的影响

摘要：渗透率低于 10 mD 的特低渗储层与平均渗透率大于 20 mD 的低渗储层开发技术政策界限和开发方案制定等有很大的差别，渗透率越低，其启动压力成倍增加，这就影响了开发技术和方案的制定。应用分段启动压力梯度进行分段计算并进行对比，计算结果表明：用同一启动压力梯度计算的结果不符合实际情况，而应用分段启动压力梯度计算的结果更能很好地反映特低渗储层的实际情况；井距对较高渗透率的驱动压力计算影响并不大，但对于特低渗储层的驱动压力计算则影响很大。     

女性在田野调查中的性别处境研究

当研究者进入田野，田野对象就会试图将研究者放置在一个位置上，而研究者也会给自身寻找一个适合的位置．田野对象对研究者的定位反映的即是一般的社会性别价值。通过对12位女性研究者进行访谈，拟了解女性研究者是否因自身性别而遭受困境，其性别先前理解又是如何影响她对于性别差别遭遇的反应的。结果发现，虽然处于不同的年龄、专业领域，拥有不同的生活阅历，女性研究者在田野中的经验却有着相似之处。即她们的专业角色被忽视，更多地被视为传统女性的角色。在这一现实背景下，为了使研究能够顺利进行。女性研究者通常的选择是表现得有礼貌或者不得不忍气吞声。     

Translating Spirituality: Universalism and Particularism in the Diffusion of Spiritual Care from the United States to Israel

Research on the transnational diffusion of ideas and practices shows how cultural objects go through translation, adaptation, and vernacularization when implemented in new localities. Less attention is given to the translators themselves and their heterogeneous and often conflicting visions. Drawing on the notion of transnational social fields (TSF s), this article investigates how cultural objects get vernacularized differently in different parts of the TSF , demonstrating how processes of translation reflect larger social and political struggles over questions of identity. As a case study, we focus on the attempt of actors from Israel and the United States to institutionalize spiritual care in Israeli health‐care organizations. The analysis reveals how spiritual care functioned as a porous cultural object, open to a wide range of interpretations and debates. While actors in New York saw in spiritual care the opportunity to bridge to Israeli Jews and create a global Jewish identity, Israeli actors split between using spiritual care as a vehicle for creating a local Israeli Jewish identity and seeing in spiritual care the opportunity to establish universal identities, broader than the Jewish one. The disagreement and conflicts between the groups influenced the translation process, turning it into a contentious struggle that involved different positions on the continuum between particularism and universalism.
