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.     

德国行政赔偿制度的特色与成因

德国行政赔偿制度有着不同于大陆法系国家和普通法系国家行政赔偿制度的特色,这种特色突出体现在行政赔偿基础的赔偿请求权和对行政赔偿案件进行救济的赔偿审理制度两个方面。德国行政赔偿制度的特色是由在漫长的历史过程中所形成的思想因素、制度因素和文化因素造就而成。     

经理收入的ISM分析(英文)

以经理的收入与经理的经营业绩相一致为假设,确定和分析了影响企业经理收入的个人、企业和外部环境因素。依据这些因素间存在的逻辑关系,运用解析结构模型(ISM)方法进行了定量处理,建立了影响经理收入因素的多级递阶结构模型。通过模型,得出企业因素对经理收入起着决定性作用,为建立有效的经理激励机制提供了理论和实际依据。     

西方企业战略更新研究

企业战略更新是21世纪战略管理学的重要主题之一。阅读大量文献后,发现西方学者从不同的角度研究战略更新问题。美国学者佛罗达等是从中层管理者的角度出发,认为中层管理者是探索战略更新的一个合适的切入点。荷兰学者沃伯达等从共同演进的视角思考了战略更新,认为战略更新是一个持续的过程,应该把环境的选择和管理的适应性相结合。荷兰学者温勒梅科等是从整合的视角探索战略更新的轨迹,他们的研究视野融入了三个维度:组织形式、管理者角色和时间维度。     

《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.     

近代新式中国史撰述的开端——论清末中国历史教科书的形式与特点

清末中国历史教科书的编纂与中国通史的撰述,因为编撰性质不同而不应将两者完全等同一致。关注中国历史教科书的编纂与中国通史的撰述之特点及其相互关系,更可得见当时新旧史学转换的种种特征在历史撰述中的具体表现。清末中国历史教科书的编纂通常被认为是开始使用了章节体,其实仍以使用纪事本末体为主,编纂形式新意无多,而其划分历史阶段的分期观念,以及受此影响而在历史叙事方式等方面的改变,其学术意义则不可忽视。清末出现的多种中国历史教科书实际上成为近代新式中国史撰述的开端。     

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).     

Improving Africa's Roads: Modelling Infrastructure Investment and Its Effect on Sectoral Production Behaviour

Given the scarce resources for public investment in developing countries, policy analysis should include a detailed perspective on the effects of infrastructure. This article develops a modelling framework for analysing the effects of improved road infrastructure on the economy of African countries. The theoretical framework is tested empirically and used for simulations in a Computable General Equilibrium (CGE) model, and the effects on production and welfare are analysed. The model also serves to investigate the effect of roads on the economic participation of rural households.
