Changing Frameworks in Attitudes Toward Abortion

For more than two decades, legal abortion has been the subject of heated political debate and adversarial social movement activity; however, national polls have shown little change in aggregate levels of support for abortion. This analysis examines how the determinants of abortion attitudes have changed between 1977 and 1996, using data from the General Social Surveys. While in early time periods, whites were more approving of abortion than blacks, that pattern had reversed by the late 1980s. After controlling for other factors, older people are more accepting of abortion throughout the two decades, while gender is generally unrelated to abortion views. Catholic religion weakens slightly as a predictor of abortion attitudes, while religious fundamentalism and political liberalism increase in explanatory power. The associations between attitudinal correlates and abortion approval also change over this time period. Religiosity becomes a less powerful predictor of abortion attitudes, while respondents' attitude toward sexual freedom and belief in the sanctity of human life increase in their predictive power. Support for gender inequality remains a weak but stable predictor of abortion attitudes. This pattern of results suggests that the public is influenced more by the pro-life framework of viewing abortion than by the pro-choice perspective.     

《史记》“互见法”再论

<史记>叙事首创"互见法",取得了很高的艺术成就.然而,今人在嘉许<史记>"互见法"首创价值的时候,对部分互见文字的真伪要谨慎,还应看到<史记>"互见法"体系并不完备,<史记>"互见法"的运用还不很自觉,特别是"互见法"对于今人还原<史记>"一家之言"的哲学真相有很大的干扰.     

延安时期的中国古代史研究

延安时期的中国古代史研究在是在相对稳定的政治环境和较为自由的学术氛围下进行的。当时学者坚持以唯物史观为指导,采用了丰富多样的历史研究手段,在立足史料,实事求是的基础上,对中国古代史上一些重大历史问题,从理论高度进行了系统的分析。其研究成果曾产生了重要的影响。但由于过分强调史学研究为现实服务,因而其科学性便受到损害,甚至在个别问题上出现了非历史主义的倾向。     

The web proxy location problem in general tree of rings networks

The Web proxy location problem in general networks is an NP-hard problem. In this paper, we study the problem in networks showing a general tree of rings topology. We improve the results of the tree case in literature and get an exact algorithm with time complexity O(nhk), where n is the number of nodes in the tree, h is the height of the tree (the server is in the root of the tree), and k is the number of web proxies to be placed in the net. For the case of networks with a general tree of rings topology we present an exact algorithm with O(kn ²) time complexity.This research has been supported by NSF of China (No. 10371028) and the Educational Department grant of Zhejiang Province (No. 20030622).     

基于调研数据的总和生育率发展趋势及影响因素分析——来自湖北鄂州、黄石、仙桃的调查数据

文章基于5490份有效问卷的调查数据对湖北省总和生育率（TFR）进行分析。结论表明,自1985年以来年龄别生育率下降主要原因是计生政策严格控制生育数量,而非生育行为的推迟。TFR呈现先快速下降后缓慢上升的趋势,其变化与高生育水平育龄妇女占比无关。与政策生育率变化有关。通过对湖北省总出生人数进行估算和分析,结论表明1985—2008年总和生育率对总出生人数的影响程度要大于高生育水平育龄妇女占比的影响;外推预测表明2009～2014年出生人数趋势稳定,2015年以后呈下降趋势。利用Logit模型对实际生育水平的影响因素进行分析,发现有显著影响的因素为：受访者文化程度、户口性质、出生年代、工作状态、丈夫工作状态、放宽的计生政策和奖励少生的计生政策。     

白寿彝先生的治学与他的中国通史编纂

白寿彝先生在历史学的许多领域都取得了卓越的成就,晚年主要集中在回族史、中国史学史、中国通史等方面,并表现出总结性、成熟性和继续创新性三个特点。其中中国通史在他的学术规模中居于核心的地位,是他一生研究历史学的最高追求。他带领国内史学家,历20个春秋,终于完成体裁新颖的多卷本中国通史,实现了一个世纪中国史家的愿望,把自己的学术事业推向了辉煌的最高点。     

Double robust estimator in general treatment regimes based on Covariate-balancing

Double robust estimators have double the chance of being a consistent estimator of a causal effect in binary treatments cases. In this paper, we proposed an estimator of a causal effect for general treatment regimes based on covariate-balancing. Under parametrical situation, our estimator has double robustness.

成都将军的设置及其在治理川西藏区中的作用

清乾隆年间对大小金川土司的用兵结束后,为了加强对康藏及川西藏族的统治,乾隆帝特设成都将军,统辖八旗和绿营,治理川边。成都将军在维护川西藏族地区的稳定、保持川藏大道的畅通、巩固西南边疆的安全等方面均起到了积极的作用。
