双渗渗流数学模型的精确解

针对双渗油藏的渗流特征,在两渗流层之间存在流体的交换;以往的双渗油藏并没有考虑流体之间的渗流,仅仅将两层之间的流体交换作为源和汇;在此考虑了两层之间渗流耦合的微分方程及压差对两层的影响,对方程采用无因次化,而将方程简化。通过正交变换获得该模型的精确解,该解对理解双渗油藏的渗流规律和试井分析都具有重要的指导意义。     

Frame Correction Modelling with Applications to the German Register‐Assisted Census 2011

Frame corrections have been studied in census applications for a long time. One very promising method is dual system estimation, which is based on capture–recapture models. These methods have been applied recently in the USA, England, Israel and Switzerland. In order to gain information on subgroups of the population, structure preserving estimators can be applied [i.e. structure preserving estimation (SPREE) and generalized SPREE]. The present paper extends the SPREE approach with an alternative distance function, the chi‐square. The new method has shown improved estimates in our application with very small domains. A comparative study based on a large‐scale Monte Carlo simulation elaborates on advantages and disadvantages of the estimators in the context of the German register‐assisted Census 2011.     

Family Migration and Subsequent Employment: The Effect of Gender Ideology

A substantial body of evidence shows gender asymmetry in family migration, with women more likely to leave employment following migration than men. Gender ideologies, although yet not tested directly, have been proposed as one determinant for these asymmetries. Analyzing longitudinal data from the British Household Panel Survey (1991–2008) on 3,333 dual‐earner couples with dyadic multilevel regression models, the author examined whether the association of family migration with subsequent employment is moderated by the gender ideologies of both partners. The existing literature is enriched by illustrating that women's gender ideologies do not moderate the association, but women with egalitarian partners are less likely to leave employment after family migration than those with traditional partners. No significant effects for men were found. Even after controlling for both partners' gender ideologies and relevant control variables, a substantial gender difference in the risk of leaving employment after family migration remains, meriting further research.     

Cognition in Situations

The symbolic interactionist tradition can contribute to advancing sociological studies of cognition by setting dual process models on more solid ground. I draw on Blumer's epistemological statements and the interactionist tradition more broadly to consider how dual process models of cognition could be applied to naturally occurring situations. I suggest that attending to the ways the past and the future are handled and modified within social interaction provides a usable inroad for the sociology of cognition to engage with situational analysis. I identify “resonance” and “iterative reprocessing” as concepts that are suitable to this end.     

新世纪以来国产电影的农民工书写

随着农民工数量的增多和国家对农民工问题重视程度的提高,国产电影逐渐把镜头对准了农民工群体。新世纪以来,国产电影对农民工的书写,主要从农民工的生存状况、心理状况、精神世界和价值追求等四个方面展开,塑造了一群性格各异的农民工形象。但也存在一些问题,需要在今后的电影创作中逐步去解决。     

意识的形而上学与两视一元论

斯瓦伯在最近的著作中提出“我即我脑”这一命题。若要在存在论和认识论上阐明心、身范畴及其关系,那么单纯的“我即我脑”这个命题不但显得“褊狭”,而且会引来不必要的误解。近代以来,科学物质主义和二元论在面对心-身问题时都有其不可解的困境。对于这些困境,有必要在两面一元论、泛心论和泛体验论的基础上提出“两视一元论”的形而上学构想。这个构想的核心观念是： 任何现实实体在存在论和认识论上都是以主体-客体统一的模式存在的,人类描述意识现象的两个范畴(即心和身)是现实实体在作为体验主体的第一人称和作为被观察的客体的第三人称视角下的分别呈现,由这两个视角所呈现的体验方面与物理方面之间的关系是一种法尔自然的相应关系,而不是产生和被产生的关系。因此，意识体验与脑神经活动之间不应该用因果作用的概念来刻画,世界的物理方面是因果封闭的,意识本身是非因果作用的。     

我国农民的二次大解放--家庭承包经营、城乡一体化探讨

随着改革开放,我国农民经历并将经历两次历史性大解放,第一次是从僵化的人民公社体制下解放出来--实行家庭承包;第二次是从传统的二元社会结构的束缚下解放出来--实现城乡一体化.前者发生在农业领域里,后者超出农业领域(乃至农村领域).我国农民只有经历这两次大解放,才有可能在促进农业发展的同时,走上富裕的道路.     

我国贫困群体社会救助制度存在的问题及成因分析

我国现行的贫困群体社会救助制度,对保障贫困群体基本生活,维护社会稳定与和谐发挥着非常重要的作用。但其仍存在着许多问题,某些问题业已成为深化经济体制改革和实现社会和谐的障碍。究其原因是多方面的,主要包括改革措施偏离制度目标、分割的二元经济结构的阻碍、政府与市场的关系没有理顺、分税制财政体制的障碍、立法理念落后以及公共决策机制不健全等六个方面。     

印度“双重国籍”政策探析

受多重因素的推动,印度海外移民政策在过去几十年间发生了巨大的变化,其中近年来新推出的"双重国籍"政策尤为引人关注,它不仅极大地推动了印度经济的快速发展,而且有力地强化了印度与海外移民间的文化认同和情感联系。然而,该政策尽管在经过不断的发展和完善后已取得了重大的进步,但与真正的双重国籍政策相比仍有很大的一段距离,海外印度人目前并没有获得印度完全的国民身份和地位。虽然前景一片良好,但该政策能否实现最后的突破仍有待继续关注。     

我国城乡二元结构破解之道:基于包容性发展的视角

城乡二元结构至今仍然是我国社会的主要矛盾和顽症之一,从问题的提出上升为执政党的执政方略倾注了学者、社会公众以及政治家的智慧和心血。包容性发展理论的提出为城乡二元结构的破解提供了新的战略方向,而转移型策略、吸纳型策略、解制型策略是当前的策略选择。
