Web2.0环境下传统新闻媒体应用UGC思辨

在Web2.0的环境下,UGC素材进入了新闻报道,同时新闻报道对UGC类型又进行选择。互联网为传统新闻媒体开辟了新"路线",并没有使新闻权威消解。然而,要想UGC繁盛下的新闻权威不被消解,关键一点新闻从业者必须坚持新闻专业主义原则。     

非理性用户模型在虚拟实验中的构建与应用

随着虚拟实验在教学中的广泛应用,如何设计合乎人自然真实状态的虚拟实验成为研究者的努力方向。传统的虚拟实验设计一般以正常的、理性的操作情况为主要对象,缺乏对学习者在非正常情景和非理性心理因素下的认知和行为特性考虑,很容易导致操作出错,增加学习者的认知负荷。因此在虚拟实验设计过程中,需将用户的非理性因素融入其中,构建非理性用户模型指导设计过程。考虑到人的非理性主要表现在认知、情绪、行动各个阶段,虚拟实验的非理性用户模型应该包括认知模型、行动模型、出错模型和环境模型四个子模型。基于非理性用户模型,虚拟实验设计应注意满足学习者的视觉意向性,合理布局界面容量及结构,优化交互设计,重视虚拟实验系统的出错预防及矫正功能,提高虚拟实验的智能性。     

如何在ASP.NET页面中动态添加用户控件

ASP.NET是一种建立在通用语言基础上的Web开发技术,可以用于开发功能强大的Web应用程序。相对于传统的ASP而言,ASP.NET在开发效率、平台无关性、安全性等方面具有显著的优势。在当今的Web开发领域,ASP.NET已经成为应用非常广泛的技术之一。本文介绍了如何在ASP.NET页面中动态添加用户控件,以及如何控制动态控件的显示格式。     

运动员肖像权保护的法律分析——从个案引申出来的法律问题谈起

肖像权是我国法律规定的每个自然人所享有的一项权利,受法律的保护,不容侵犯。有些较知名运动员无疑是社会公众人物,其形象为社会大众所熟悉,其行为也会带来一定的社会效果,所以从这个意义上来说,运动员的肖像权的保护就有了一定的特殊性。文章通过对国内一起著名的运动员肖像权诉讼案件的分析,指出了在我国运动员的肖像权应属于个人,集体肖像权也应在今后的立法中作出相应规定,并提出了在我国运动员维护其肖像权的途径。

Examining the effect of user satisfaction on system usage and individual performance with business intelligence systems: An empirical study of Taiwan's electronics industry

The advent of new information technology has radically changed the end-user computing environment over the past decade. To enhance their management decision-making capability, many organizations have made significant investments in business intelligence (BI) systems. The realization of business benefits from BI investments depends on supporting effective use of BI systems and satisfying their end user requirements. Even though a lot of attention has been paid to the decision-making benefits of BI systems in practice, there is still a limited amount of empirical research that explores the nature of end-user satisfaction with BI systems. End-user satisfaction and system usage have been recognized by many researchers as critical determinants of the success of information systems (IS). As an increasing number of companies have adopted BI systems, there is a need to understand their impact on an individual end-user's performance. In recent years, researchers have considered assessing individual performance effects from IS use as a key area of concern. Therefore, this study aims to empirically test a framework identifying the relationships between end-user computing satisfaction (EUCS), system usage, and individual performance. Data gathered from 330 end users of BI systems in the Taiwanese electronics industry were used to test the relationships proposed in the framework using the structural equation modeling approach. The results provide strong support for our model. Our results indicate that higher levels of EUCS can lead to increased BI system usage and improved individual performance, and that higher levels of BI system usage will lead to higher levels of individual performance. In addition, this study's findings, consistent with DeLone and McLean's IS success model, confirm that there exists a significant positive relationship between EUCS and system usage. Theoretical and practical implications of the findings are discussed.
