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.

关于大学英语写作教学实践的调查与反思

本研究以第二语言写作理论为指导,对五所高校的大学英语写作教学现状进行抽样调查。调查结果表明,学生写作能力欠佳的原因主要来自于教师的教及学生的学等不同的层面。为提高大学英语写作教学的质量,在教学中教师应该改变现有的教学模式,加强英语写作地位;合理设置写作任务,激发学生写作动机;加强目的语输入,扩大学生积极词汇量。

On calculating the fisher information in order statistics

This article gives a simple result for the expression of the Fisher information in order statistics. This result enables us to calculate easily the Fisher information in any set of order statistics whose details have been known to be messy and complicated. We consider here its application in the optimal spacing problem where the exact Fisher information in order statistics has been approximated with the asymptotic information or the reciprocal of the variance of a suitable estimator.

Web数据库性能调优(英文)

提出了一种基于Web数据库系统设计、实现和性能调优的新方法,该方法包括由RDBMS配置优化、应用模式设计优化和编程优化。通过内存、分段、磁盘参数和时间相关参数的优化可以设置一个好的RDBMS运行环境。在编程时,通过减少与后台连接和断开操作、建立和使用索引、多用存储过程和优化SQL语句可以优化系统性能。在应用设计时,通过优化应用逻辑和降低规范化可以大大地改善系统性能。

网络法问题的法哲学分析

计算机网络的发展引起了一系列的网络法问题 ,而针对网络法问题的研究目前主要集中在部门法学领域 ,对网络法问题的法哲学探讨还很少。立足于法哲学理论 ,在阐释了法哲学的任务、网络中存在的私人领域和公共领域模糊性表现的基础上 ,提出了网络法问题的本质就在于网络条件下私人领域和公共领域的界限的模糊 ,提出了该模糊性是导致网络条件下自由的边界模糊和权利冲突的根本原因。并在此基础上提出了一些建议性的解决网络法问题的法哲学思路。

Trends in online media relations: Web-based corporate press rooms in leading international companies

An analysis of 120 corporate websites from Denmark, France, Germany, Norway, Singapore, Spain, the United Kingdom and the United States reveals, for the first time, international results about the implementation and use of virtual press rooms. This article shows the importance that large international companies attribute to Web-based media centers to achieve organizational objectives and to meet journalists’ demands for information and audiovisual resources. The study also shows, however, that most press rooms are far from being complete, efficient, easy-to-use, reliable and updated on a daily basis. In fact, there is not a single country from those analyzed that consistently stands out from the rest. In most of them, good results in certain areas coexist with significant shortcomings in others, resulting in some cases in poor press rooms that may not achieve the desired public relations objectives.
