Do websites influence the nature of voting intentions? The case of two national elections in Greece

This paper aims to contribute to the growing body of research on online political marketing by investigating the use of websites as a marketing tool in the 2007 and 2009 general elections in Greece. The two main research objectives are firstly to establish the key factors affecting voters’ trust when it comes to using politicians’ websites and secondly to examine whether and to what extent the influence of trust-building factors changes over-time, as the online environment matures. The key findings of this research are that users tend to visit the websites of favoured candidates, which reinforces their positive perceptions of them, while as far as the websites themselves and their content and the services provided are concerned there is still room for improvement.     

Computer-mediated persuasion in online reviews: Statistical versus narrative evidence

The current study examined the effects of online product reviews on individuals’ credibility perceptions of the reviews and their attitudes about the product targeted in the reviews. Study 1 used a 2 (review type: statistical and narrative) × 2 (review valence: negative and positive) design, and study 2 used a 2 (statistical review valence: positive and negative) × 2 (narrative review valence: positive and negative) design. The findings of study 1 were consistent with those of study 2 and indicated that negative statistical reviews were perceived as more credible than negative narrative reviews, while the credibility of positive statistical reviews did not differ from that of positive narrative reviews. On the other hand, statistical reviews and narrative reviews did not differ in terms of affecting individuals’ attitudes about the product. The current study also found that the vividness and valence of each review type had varying effects on review credibility and attitudes about the product. The implications of these and other findings are discussed in detail in the paper.     

电厂热力系统在线性能计算软件变量二维顺序及索引模型研究

分析在线性能计算软件在我国电厂的应用情况,把在线性能计算软件分为两类:编程式软件和组态式软件。编程式软件里的计算模型和变量值是完全被封装的,软件基本不具备扩展性。现有的组态式软件虽然具备一定的扩展性和可分析性,但是功能仍不够完善。提出在线性能计算软件变量二维计算顺序及索引模型,该模型包括三方面内容:第一,定义及构造了与计算变量和计算顺序相关的一系列集合和有序序列;第二,提出了变量二维排序算法;第三,建立了变量之间的引用和被引用关系,建立了变量二维索引图表。基于变量二维索引图表,可以方便地逐级追踪计算模型和计算变量的值,有利于增强组态软件的可分析性、扩展性和组态功能。

网上拍卖的风险防范机制及其发展研究

网络经济的发展促使电子商务得到快速应用,而网上拍卖是电子商务中最成功的一种形式。网上拍卖有着传统拍卖所没有的一些优点。随着计算机技术和网络技术的发展,网上拍卖日益广泛与深入,同时也使得网上拍卖系统的风险问题日益突出。本文考虑的就是通过建立一些风险防范机制来降低网上拍卖的风险。     

牵引变压器模糊故障诊断技术

牵引变压器是牵引供电系统的重要组成部分之一，对其DGA成分和含量进行在线监测并进行故障判断，能有效地提高电气化铁路运行可靠性。目前对变压器的故障性质判断大多是根据IEC三比值法进行的。而实践中，一些DGA结果与已存在的IEC编码不符，或造成缺码现象。论文采用模糊三比值诊断法进行故障性质判断能有效地解决这一问题。

基于网络的教学支撑平台的设计

目前国内外的网上教学支撑平台有一个共同的缺点,就是教材的制作不方便,需要教师较多地掌握网上教材制作技术,而且大多缺乏良好的师生交互机制。文章提出的网上教学支撑平台,并不需要教师具备IT背景,可方便利用系统自动生成网上课程。此外,该平台还增添了许多新的特色,如教学内容的多媒体化和个性化、教师直接管理和更新自己的网上讲义、在线考试机制、多重交互管道等。文章给出了系统结构、主要界面、功能模块。
