Web site credibility: Why do people believe what they believe?

This research investigates university students’ determinations of credibility of information on Web sites, confidence in their determinations, and perceptions of Web site authors’ vested interests. In Study 1, university-level computer science and education students selected Web sites determined to be credible and Web sites that exemplified misrepresentations. Categorization of Web site credibility determinations indicated that the most frequently provided reasons associated with high credibility included information focus or relevance, educational focus, and name recognition. Reasons for knowing a Web site’s content is wrong included lack of corroboration with other information, information focus and bias. Vested interests associated with commercial Web sites were regarded with distrust and vested interests of educational Web sites were not. In Study 2, credibility determinations of university students enrolled in computer science courses were examined for 3 provided Web sites dealing with the same computer science topic. Reasons for determining Web site inaccuracy included own expertise, information corroboration, information design and bias. As in Study 1, commercial vested interests were negatively regarded in contrast to educational interests. Instructional implications and suggestions for further research are discussed. Preliminary results from Study 1 were presented as a poster entitled “Users’ Confidence Levels and Strategies for Determining Web Site Veracity” (Iding et al. 2002a) and appeared in associated proceedings for The WWW 2002: The Eleventh International World Wide Web Conference, in Honolulu, Hawaii. Preliminary results from Study 2 were presented as a paper entitled, “Judging the Veracity of Web Sites” (Crosby et al. 2002) and appeared in associated proceedings for the International Conference on Computers in Education (ICCE 2002) in Auckland, New Zealand.

Aesthetics and credibility in web site design

Web sites often provide the first impression of an organization. For many organizations, web sites are crucial to ensure sales or to procure services within. When a person opens a web site, the first impression is probably made in a few seconds, and the user will either stay or move on to the next site on the basis of many factors. One of the factors that may influence users to stay or go is the page aesthetics. Another reason may involve a user’s judgment about the site’s credibility. This study explores the possible link between page aesthetics and a user’s judgment of the site’s credibility. Our findings indicate that when the same content is presented using different levels of aesthetic treatment, the content with a higher aesthetic treatment was judged as having higher credibility. We call this the amelioration effect of visual design and aesthetics on content credibility. Our study suggests that this effect is operational within the first few seconds in which a user views a web page. Given the same content, a higher aesthetic treatment will increase perceived credibility.     

管理者消极情绪研究

在现代社会中,人们面临着越来越大的压力,这些都直接影响着其情绪.情绪分为积极的情绪和消极的情绪.积极的情绪可以使人积极向上,消极的情绪可能给人们带来非常大的危害.管理者的消极情绪对于组织情绪管理来说,尤其具有特别重要的意义.本文以管理者消极情绪为切入点,深入探讨了管理者消极情绪来源的构成、影响因素及其管理者消极情绪与工作绩效的关系.     

数字图书馆使用开放源码软件中的知识产权问题

开放源码软件是一种新型的软件开发模式,其代码透明,价格低廉的主要特点非常适用于经费紧张而又面临社会化、网络化需求的数字图书馆使用。但开放源码软件不是免费的。数字图书馆对开放源码软件的选择使用必须遵守以使用许可方式进行的知识产权保护制度,在《著作权法》、《专利法》等法律制度允许范围内合理降低数字图书馆运营成本。     

Citizen Satisfaction with Public Meetings Used for Risk Communication

Although public meetings are a frequent method of public participation and risk communication, little research investigates what citizens think about their use in environmental management. To examine satisfaction with public meetings, residents of two neighboring communities received questionnaires following a public meeting about a local landfill. Respondents included residents who did and did not attend the meeting. Irrespective of whether respondents had ever attended a public meeting, meeting expectations and perceptions of relational/informational communication at meetings, including whether respondents thought meeting organizers were genuinely interested in participants' comments or meetings were informative, predicted satisfaction. Perceived risk associated with the recent meeting's topic and credibility of government agencies that frequently conduct meetings also predicted satisfaction.     

外部因素对维基百科序化过程的影响分析

维基百科是一个开放的知识系统,从而不可避免地受到外部环境的影响。本文以维基百科为研究对象,选择了"可信度危机"和"政府限制访问"等若干具有代表性的因素,研究了外界环境对维基百科序化过程的影响。结果表明,外部因素的确影响了维基百科的发展,但是并没有遏制其发展趋势。     

It’ll Be Okay,Because We Belong Together: The Influence of Person-Organization Fit on Interpretation of Bad-News Messages in Academic Settings

Higher education has recently faced significant budget cuts. In response, academic leaders must communicate negative information to stakeholders while simultaneously attempting to maintain morale and credibility. This project investigated how students interpret a bad-news message from the university president and examined the impact of person-organization fit and demographic characteristics on interpretations and credibility. In Study 1, participants (N = 52) provided 19 varying interpretations for a real-life message. Using 5 components derived from the interpretations, Study 2 (N = 466) determined that person-organization fit and demographic characteristics influence interpretations and source credibility. Some outcomes varied according to whether participants had previously read the bad-news message.     

江河源区高山嵩草草甸覆被变化对植物群落特征及多样性的影响

本研究是在青海省达日县青珍乡进行的，分析了高山嵩草草甸不同退化演替阶段覆被变化与植物群落特征、多样性关系。研究结果表明：轻度退化草地、中度退化草地、重度退化草地物种数分别占研究区物种数的58.93%、73.21%、66.07%。原生植被的优势种高山嵩草随退化程度的加剧而逐渐减少，其优势度分别为27.13%、12.37%、1.82%。物种多样性指数依次为中度退化演替阶段（3.41）>重度退化演替阶段（3.39）>轻度退化演替阶段（2.99）；均匀度指数依次为重度退化演替阶段（0.94）>中度退化演替阶段（0.92）>轻度退化演替阶段（0.86）。地上生物量中度退化草地最大，轻度退化草地居中，重度退化草地最低。随着退化程度的加剧，禾草类和莎草类植物的生物量减少，而杂类草增加。轻度退化草地地下生物量明显高于退化草地。相关分析表明，植被盖度与土壤含水量之间呈极显著的正相关关系（p<0.01）。     

试析高考改革难以宏观突破的原因

以分数简单相加,作为高校选拔、录取学生、培养人才的唯一依据,是目前中国高校招生改革的症结所在。当中国高考改革进入攻坚阶段后,需要的是更为彻底的全民思想解放运动。微观层面上的变革固然重要,但若没有宏观层面上的制度设计和制度创新,高考改革则难以迈出大步子。高考改革并非单纯的教育改革,是社会变革大系统中的子系统,传统文化、社会环境,都需要加以理性审视。分数公平、智育至上、诚信缺失导致的阻抗改革等观念,都值得反思与批判。
