关于自杀行为的城乡跨文化十年研究成果综述

通过检索1994￣2004年CNKI数据库中收集的心理学类论文,从自杀率、自杀方式、自杀原因、自杀态度、自杀倾向和危机干预策略方面分类比较了近十年来我国自杀行为的城乡跨文化研究成果,进一步揭示和分析了自杀行为的城乡差异和造成这种差异的原因,认为应将更多的目光投向农村,关注农村地区人群的自杀危机干预系统的建立和特定人群(女性和老年人)的心理卫生工作。     

中西政党制度比较分析

基于匹配点逐层过滤的岩体点云配准方法

岩体点云配准是岩体三维重建与分析的基础。经典的点云配准方法虽然能够很好地适用于普通点云,但对于岩体点云并不能获得足够的精度。由于岩体点云表面结构复杂,且大部分区域为平面,基于岩体点云的这些特点,提出通过几何特征逐层过滤匹配点的岩体点云配准算法,引入匹配点对的协方差矩阵的特征值和特征向量矩阵,以及曲率、主方向等几何特征逐层过滤匹配点对,精确地找到匹配点对。在不同岩体点云上的实验测试与分析结果表明,该算法在准确度上有明显优势。

Analysis of Statistical Question Classification for Fact-Based Questions

Question classification systems play an important role in question answering systems and can be used in a wide range of other domains. The goal of question classification is to accurately assign labels to questions based on expected answer type. Most approaches in the past have relied on matching questions against hand-crafted rules. However, rules require laborious effort to create and often suffer from being too specific. Statistical question classification methods overcome these issues by employing machine learning techniques. We empirically show that a statistical approach is robust and achieves good performance on three diverse data sets with little or no hand tuning. Furthermore, we examine the role different syntactic and semantic features have on performance. We find that semantic features tend to increase performance more than purely syntactic features. Finally, we analyze common causes of misclassification error and provide insight into ways they may be overcome.     

How U.S. and Chinese journalists think about plagiarism

A comparison of 1,096 professional journalists in China and the United States on attitudes toward attribution and plagiarism reveals Chinese journalists were more likely to see attribution as a practice to be embraced regardless of career longevity and culture, suggesting journalistic norms are more important than a collectivist orientation. Attribution was more likely to be embraced by those who see principles as more important than expediency, affirming research that plagiarism is hardly a monolithic concept. Overall, journalists in the two nations did not vary significantly in their attitudes toward plagiarism, despite vast differences in culture and politics as well as evidence that in some other fields China is more accepting of reusing material without attribution. The data show that among journalists, attitudes toward plagiarism are shared across national boundaries, reinforcing related research showing that a journalism culture exists and is shared at least in part across national boundaries.     

COUNTER R5的新特性及对图书馆的影响

COUNTER是规范网络化电子资源使用统计报告数据处理、审核和提交的国际化标准,是图书馆电子资源使用量统计和评估的核心要素。目前COUNTER已经发布了最新版本R5,了解R5的新特性及与之前版本的不同对于图书馆的电子资源统计工作具有重要意义。本文拟从COUNTERR5的报告设置、报告的指标类型、数据类型、访问类型和其他完善报告的属性来解析R5,同时介绍R5对SUSHI收割的影响、"持续维护"的概念、R5发布对图书馆的影响和R5实施的重要时间节点,同时也对R5较之R4的发展和不同进行了比较和分析。COUNTERR5的主要关注点是一致性、清晰性和简单性,较之COUNTERR4有了明显的完善,同时包含了持续的维护过程,允许对代码进行更新而不必再引入一个全新的版本,解决了版本升级会对供应商和图书馆带来的各种时间和人员成本的影响。
