"九·一八事变"对东北农村宗族结构的影响

"九·一八事变"后,日本殖民势力深入中国东北农村,冲击了东北农村社会的宗族制度,使得民初以来宗族的变迁过程发生逆向性发展,宗族制的弱化过程发生改变而出现强化趋势,中断了中国东北农村社会正常的变迁过程.     

对九一八国耻日纪念的考察与反思

《申报》和《人民日报》分别作为民国时期和人民共和国时期第一大报,主要就历年九一八前后,国人(尤其是党政界和教育界)对这一国耻日所开展的纪念活动进行报道。今昔对比,社会各界对于九一八国耻日之纪念各方均有不同演变,如今我们纪念九一八国耻日在如下四个方面值得反思:需要忧患意识;需要合理方式;需要理性认知;需要全民意识。

Settlement policies and the economic success of immigrants

Many countries use settlement policies to direct the inflow of immigrants away from immigrant dense areas. We evaluate a reform of Swedish immigration policy that featured the dispersion of refugee immigrants, but also a change in the approach to labor market integration. We focus on how immigrants fared because of the policy. The evaluation indicates that immigrants experienced substantial long run losses. The bulk of the effect stems from a common component that affected immigrants regardless of location. We interpret the common component as being related to a shift in policy focus, from labor market assimilation to income support.All correspondence to Per-Anders Edin.

We are also grateful to Sven Hjelmskog, Roland Jansson, Stig Kattilakoski, Christina Lindblom, Anders Nilsson, Kristina Sterne, and Lena Axelsson of the Immigration Board, and Anna Gralberg of the Ministry of Culture, who generously found time to answer our questions.

中国抗日战争应以七七事变为开端——兼与郭德宏先生商榷

中国抗日战争从九一八事变开始的观点是值得商榷的,因为九一八事变后,抗日并没有成为中国政治生活的主流,当时中国政局的关键仍然是如何结束国内政局的分裂与动荡状态,以实现国家的统一;九一八事变后,中日之间的战争仍只是属于局部战争,而中日两国并没有进入国与国之间的一种全面战争状态。只有到了七七事变之后,抗日才真正成为中国社会压倒一切的时代主题,中国抗日战争因此应从七七事变算起比较合适。

法国汉学界对中西文化首次撞击的研究(下)

明末清初的16-18世纪,是中西两种文化首次撞击的时代。这次中西文化的撞击与交流媒介,是以入华耶稣会士为主体的西方天主教传教士。他们无论是在中学西渐方面,还是在西学东渐领域中,都做了许多有益的、他人无法取代的工作。入华耶稣会士与中西文化交流,是近年来国际学术界的热门课题,法国汉学界在该领域中始终居领先地位。本文对法国汉学界近二十年来的研究成果作了鸟瞰式评介。     

EXPONENTIAL‐GROWTH BIAS AND LIFECYCLE CONSUMPTION

Exponential‐growth bias (EGB) is the tendency for individuals to partially neglect compounding of exponential growth. We develop a model wherein biased agents misperceive the intertemporal budget constraint, and derive conditions for overconsumption and dynamic inconsistency. We construct an incentivized measure of EGB in a US‐representative population and find substantial bias, with approximately one third of subjects estimated as the fully biased type. The magnitude of the bias is negatively associated with asset accumulation, and does not respond to a simple graphical intervention.
