Reduction of Face‐to‐Face Contact Hours in Foundation Research Courses: Impact on Students' Knowledge Gained and Course Satisfaction

This study investigated the impact of reducing the number of face‐to‐face contact hours in a Masters of Science in Social Work (MSSW) foundation research course in an urban school of social work on students' knowledge gained and course satisfaction. A quasi‐experimental pretest/posttest comparison group design was used to test the following hypothesis: reducing the number of face‐to‐face contact hours will not negatively impact knowledge gain and course satisfaction in a foundation research course. The findings of this study suggest that reducing the number of face‐to‐face contact hours does not negatively affect student learning as both the comparison and the experimental group demonstrated an increase in foundation research knowledge. The level of course satisfaction was influenced by the number of hours completed in the program, age, and the number of hours worked in paid employment. Students who are especially vulnerable are younger students who have completed less course hours. They tend to struggle at the beginning to get used to new technology as part of their educational experience. This paper demonstrates that it is no longer ‘if’ web‐based and distance learning technologies are appropriate for social work education but rather ‘when’ and the degree to which their integration yields greatest educational value.     

A Study of Online Auction Sellers’ Intention to Switch Platform: The Case of Yahoo!Kimo Versus Ruten_eBay*

The study of consumers’ switching from one service provider to another has a long tradition in economics, information systems, and marketing. The emergence of electronic commerce presents new challenges in understanding consumers’ switching intentions in the context of e‐commerce in general and online auctions in particular. With the abundance of literature on online auctions, there is a surprising lack of research on auction sellers’ intentions to switch from one online auction platform to another. Using the competition between Yahoo!Kimo and Ruten_eBay, two leading auction platforms in Taiwan, as the backdrop, we developed a research model and collected empirical data based on this real case to study what factors influence auction sellers to switch to a competing service provider. We find that the higher the procedural switching costs, financial switching costs, relational switching costs, site design quality, or interaction quality, the lower the intention of an auction seller to switch to a competing auction service provider. A higher perceived transaction fee, however, leads to a higher switching intention.     

人肉搜索现象探析

近年来,人肉搜索已成为网络上的一个热门话题.它的兴起首先是由于Web2.0技术的发展为网民的交流互动提供了技术支持,从而实现了网络信息的海量化发展;其次是由沉默的螺旋所形成的舆论氛围吸引了大量网民的参加.人肉搜索的特点在于它体现了一种庶民"狂欢",在道德面纱的遮掩下广大网民通过人肉搜索不仅满足了多种心理诉求,同时也找到了一种群体宣泄的路径.由于人肉搜索在发展过程中出现了一系列的问题,这就需要我们不断提高网民的媒介素养.

How climate change organizations utilize websites for public relations

This study is designed to examine climate change organizations (CCO)’s online public relations. It analyzes CCOs’ communicative efforts to build and maintain relationships with key stakeholders including media, donors, volunteers, and communities by using their websites and social networks. To accomplish this, a content analysis of 60 CCO websites was conducted. The result indicates that CCOs utilize websites primarily for media relations and fund raising purposes. The function of building and maintaining relationships with communities, current donors/volunteers was not actively utilized on CCOs’ websites. The interactivity of communication with stakeholders was somewhat limited in CCO's online communication activities.     

结构和内容联合提取的XML网页分类研究

针对XML网页特点,重点研究了XML文档结构和内容特征的提取方法,提出了一种基于频繁结构层次空间模型的联合特征提取策略,并给出了结构特征权重和关键词出现的位置及频度权重的计算公式,并根据计算结果提取XML网页特征矩阵,分别就结构、内容联合提取三种情况进行分类测试,通过ROSSETA系统,利用粗糙集优越的属性约简构造文本分类系统,实现XML文档分类。实验表明,该方法分类准确度较高,计算量较小。

非周期TBox框架下的推理——拟经典描述逻辑与超协调表演算(英文)

源自当今互联网的语义网研究的目的是定义信息语义和网络服务,因此需要赋予网络智能以便能够自动对网络内容进行推理。各种描述逻辑(DLs)在语义网的研究中扮演着重要角色,构成了W3C推荐的网络本体语言(OWL)的基础,而OWL源于为达到语义网目标的人工智能(AI)本体论研究。语义网的知识和数据量巨大、分散、来源众多且因此通常不具有协调性。因此,必须开发针对非协调本体的实用的推理技术。该文基于Hunter的拟经典逻辑(QCL),构造了新型超协调拟经典描述逻辑(QCDLs),避免了逻辑爆炸问题,同时,针对基于非周期TBox的知识库推理问题,建立了QCDLs语义表演算,进而定义了一种可靠、完备且可判定的推理关系,从而构建了完整的语义网推理框架。与其他重要的超协调描述逻辑进行了比较,结果表明QCDLs具有更强的表达语义和推理能力,并且其相关行为在目标层次上表现出经典性。
