在线辅导基本要素

该文是作者在英国进修期间对在线辅导所做的一些研究,它主要阐述了在线辅导的一些基本概念,分析了在线学习的学习支持以及教学策略,最后提出了具体的实施方法。希望以此向从事在线教学的教师提供一些有价值的参考。     

Creating a departmental culture for communication grants

Extramural funding to support communication research influences and is influenced by the culture of our discipline, universities, and departments. Both the National Communication Association and the International Communication Association have established closer ties to funding agencies and encouraged members' grant writing pursuits through mentorship and convention programs, newsletter columns, and publicity. Universities vary in how much support they have available as infrastructure to assist in the submission and administration of grants. Some institutions facilitate extramural funding endeavors through mentoring programs, university-wide research centers, sharing of indirect costs, and space. Department cultures, too, vary in the resources available to support grants. Departments in many ways have the most direct effects on grant-supporting cultures. In addition to activities indicated for the discipline and university, departments can build a grant culture by recognizing grant writing in their personnel practices, creating systems for rewarding and supporting grant activities, and having policies in place for the many related issues (e.g., release time, indirect cost sharing, research assistants). Finally, the interpersonal culture, whether colleagues recognize and support grants, plays a major role in individual pursuit of, and satisfaction with, seeking extramural funding to support communication research.     

以地方特色理念构筑全国文化信息资源共享工程资源建设与服务体系

全国文化信息资源共享工程作为公共文化建设重点工程,对公共图书馆和基层文化站的自动化、网络化,以及资源建设和大众服务方面发挥了巨大的推动作用。公共图书馆大规模开展数字资源建设,形成了丰富的优秀文化信息资源。面向基层服务的数字资源提供能力显著增强。资源建设和对外服务犹如共享工程的两大推进器,因此,必须围绕地方特色资源,构建共享工程资源库群,以及创新地方特色服务,构筑共享工程服务体系。     

关注弱势群体——联合图书馆的外来工服务

作为公益性文化机构之一,公共图书馆在改善弱势群体文化生态中具有不可替代的优势和职责。禅城区联合图书馆为外来工群体服务的探索与实践包括:以有针对性的文献信息资源建设,倡导学习、阅读;以图书馆服务为纽带,开展丰富多彩的文体活动,提供自我展示与提升的文化平台;开设专题培训与自助培训,成为外来务工人员的文化交流中心和自助培训基地;激发外来务工人员参与意识,发挥其主动性和积极性。     

用户满意:服务质量评价新模式

分析了用户满意在图书馆服务质量评价中的合理有效性,探讨影响用户满意的因素以及提高用户满意度的若干策略。     

基于支持向量机的文本自动分类试验研究

提出了将支持向量机应用于文本自动分类的研究，与常用的K-最邻近法相比，无论是对训练数据集还是测试数据集均具有一定的优势，而且不同特征选择方法对支持向量机的影响要比K-最邻近法小。此外，从研究中的不同特征选择的评价函数来看，它们对分类有一定的影响，应用X2统计进行特征选择的分类正确率最高，其次是文本证据权，而期望交叉熵的效果最差，说明特征选择在文本自动分类中也是相当重要的。     

论网站信息咨询服务模式

目前,对于网站信息咨询概念的认识尚不统一。网站信息咨询的主要模式有:基于资源重组的知识化信息服务,依托应用系统的智能化服务,基于用户需求的个性化服务,基于实时联动的交互式咨询服务等等。网站咨询服务具有快捷方便、超越时空、动态发布、资源共享、智能管理、安全可靠、实时交互、服务主动等优点。其存在的问题主要表现于思想认识、经费投入和技术、法规保证方面。参考文献8。     

基于机器学习的自动文本分类模型研究

基于机器学习的方法是自动文本分类中非常重要的一大类方法。本文先给出了形式化的定义，提出了自动文本分类的流程模型，然后选取了支持向量机（Support Vector Machine，SVM）算法作为一个典型例子进行分析，最后作者通过一个中文文本分类实验评价了该算法的效果。     

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.     

Co-rumination and Immune Inflammatory Response in Healthy Young Adults: Associations with Interleukin-6 and C-Reactive Protein

A rich literature exists reinforcing the notion that both perceived and received social support has stress ameliorating and protective benefits both psychologically and physiologically. However, recent literature suggests that excessive dyadic negative problem talk about an issue, a phenomenon labeled co-rumination, may reverse much of the beneficial effects of social support. Healthy young adults participated in a laboratory research study exploring the associations between co-rumination and immune system inflammatory response. Partial correlations indicated a positive association between co-rumination and C-reactive protein and a negative association between co-rumination and interleukin-6 after controlling for stress, anxiety, and temperature. Discussion focuses on the means by which co-rumination may lead to negative health outcomes.
