Federated searching and usability testing: Building the perfect beast

With the ubiquity of federated search tools as viable solutions for students and researchers to search across external sources and internal repositories, users have become more sophisticated in their application of this technology. With the goal of optimizing the user experience of its newly introduced federated search offering, Endeavor Information Systems employed usability testing to gain insights into the critical requirements of librarians and information professionals for this solution. The results of this analysis, conducted in concert with market research and customer focus groups, and their relevance to Endeavor's federated search technology are the focus of this article.

区间型符号数据的因子分析及其应用

符号数据分析是一种新兴的数据挖掘技术,区间数是最常用的一种符号数据。基于误差分析理论,研究针对区间数据的因子分析方法。将区间数看作一个由中点和半径构成的有序偶,并将半径视为区间数的极限误差。对中点样本阵进行因子分析,得到因子得分的中点值。然后将半径样本阵按照误差传递公式,得到因子得分的极限误差。由因子得分的中点值和极限误差最终得到因子得分的区间值。最后以股票的市场综合表现评价问题为案例,进行了应用研究。     

SPECIAL ISSUE： DIALOGUE,INTERACTION AND NEW DEVELOPMENTS IN PHILOSOPHY IN CONTEMPORARY CHINA- SPECIALIST FORUM ON CHINESE,WESTERN AND MARXIST PHILOSOPHIES：Convergence of Chinese,Western and Marxist philosophies： reflections on a metaphilosophy and methodology for innovation in contemporary Chinese philosophy

当代中国哲学创新，是根据所要构建的新哲学理所当有的时代性以及由其时代性所决定的新哲学所必有的学术特征，凭由综合中、西、马各种不同哲学观而加以灵活变通的处理与转换得来的具体方法，建造出一个在研究范围上向原始哲学回归，在研究路径上走马克思主义哲学之路，在研究内容上对以往中、西哲学有继承性扩展，以和谐精神为内核的马克思主义后现代哲学。     

生态消费模式:社会主义生态文明建设的必然选择

当前,伴随着经济的快速发展,我国新富群体中存在着一种"病态式消费"现象,加上西方消费主义影响,引发了诸多的社会问题。实践证明,只有树立正确的消费观念、克制消费欲望、调整消费行为,才能建立生态消费模式,才能符合社会主义生态文明的要求,实现人与自然的协调发展。     

“废墟”诞生“花”的海洋——论诗歌精神的大规模还乡

诗歌精神是民族、时代和个人的宝贵财富。诗歌的外在生存环境制约着诗歌精神的发展,时代的困窘,诗歌精神一度衰微,致使集体还乡的艰难。汶川地震发生后涌现出大量的诗篇,诗歌的青春和活力再次不可遏止的迸发,那撼动人心的诗性光辉预告着诗歌精神大规模的回归与还乡。     

也谈简体字

在政治更迭、文化变迁的大叙事中，小小的文字变化最能体现大时代的风貌。古有始皇帝威权下的“书同文”，今有上世纪五十年代初旨在“汉字拉丁化”的“文字简化运动”。简化字与繁体字争议的背后，是政治激进主义与文化保守主义的思想交锋，或者说是中华历史文化断裂与传承的别一选择。周清泉先生关于“汉字简化方案”实施中的管见，因于当时话语权被肆意剥夺而无处表达，本刊编发该文，一是提供关于汉字简化的反思与总结，二是彰显学人发表独立见解的历史进步。     

A segmented regime-switching model with its application to stock market indices

This paper evaluates the ability of a Markov regime-switching log-normal (RSLN) model to capture the time-varying features of stock return and volatility. The model displays a better ability to depict a fat tail distribution as compared with using a log-normal model, which means that the RSLN model can describe observed market behavior better. Our major objective is to explore the capability of the model to capture stock market behavior over time. By analyzing the behavior of calibrated regime-switching parameters over different lengths of time intervals, the change-point concept is introduced and an algorithm is proposed for identifying the change-points in the series corresponding to the times when there are changes in parameter estimates. This algorithm for identifying change-points is tested on the Standard and Poor's 500 monthly index data from 1971 to 2008, and the Nikkei 225 monthly index data from 1984 to 2008. It is evident that the change-points we identify match the big events observed in the US stock market and the Japan stock market (e.g., the October 1987 stock market crash), and that the segmentations of stock index series, which are defined as the periods between change-points, match the observed bear–bull market phases.

反馈交易规则与股票收益自相关实证分析

研究了反馈交易规则与上证综合指数日收益自相关之间的联系，样本取自上证指数１９９２年９月２９日至１９９７年９月３０日的日收益率数据。此外，文中采用ＧＡＲＣＨ（１，１）处理收益波动的异方差性，模型参数采用极大似然估计。实证模型还考虑了非同步交易引起的工序列相关以及反馈交易的非对称性。结果表明，除以往文献涉及的正序列相关外，正反馈交易将导致收益负的序列自相关，且相关系数绝对值随波动增大而增大，从而整个收益表现出随波动变化的序列相关。
