Credibility influences a user’s interest in a web site. Once users perceive the credibility of a web site they will be more likely to use it. A combination of factors affects such credibility – such as the provider, content, aesthetics, accessibility and solution of technical problems. The aesthetics of a web site can affect a user’s first impressions of credibility. Experiments have shown that...

With the fast development of Social Networking Services (SNS) such as Twitter, which enable users to exchange short messages online, people can get information not only from the traditional news media but also from the masses of SNS users. However, SNS users sometimes propagate spurious or misleading information, so an effective way to automatically assess the credibility of information is requ...

The purpose of this study was to develop a psychometric questionnaire in order to evaluate the educational web site “Youth 2004” considering the attitudes and the perceptions of Greek Australian students. In addition, the differences among the age and sex were also investigated. Participants were 317 Greek Australian students, between the ages from 12-17 years old. Data was collected using an o...

I argue that taking the Practical Conditionals Thesis (PCT) seriously demands a new understanding of the semantics of such conditionals. Practical Conditionals Thesis: A practical conditional [if A][ought(B)] expresses B’s conditional preferability given A Paul Weirich has argued that the conditional utility of a state of affairs B on A is to be identified as the degree to which it is desired u...

communication and information literacy fields about the skills that Internet users need to assess the credibility of online information. The article reviews current recommendations for credibility assessment, empirical research on how users determine the credibility of Inter-net information, and describes several cognitive models of online information evaluation. Based on the literature review ...

There are various types of uncertainty in the real world. This is a motivation to investigate the behavior of uncertain phenomena. Random phenomena is one class of objective uncertain phenomena which has been well studied. Probability theory is an efficient tool to study the behavior of random phenomena. Besides randomness, fuzziness is a basic type of subjective uncertainty initiated by Zadeh....

In this paper we discuss a possible approach to confident prediction from data containing missing values presented in a probabilistic form. To achieve this we revise and generalize the notion of credibility known in the theory of conformal prediction.

Cognitive radio (CR) has become a tempting technology that achieves significant improvement in spectrum utilization. To resolve the hidden terminal problem, collaborative spectrum sensing (CSS), which profits from spatial diversity, has been studied intensively in recent years. As CSS is vulnerable to the attacks launched by malicious secondary users (SUs), certain CSS security schemes based on...

Inoculation techniques from social psychological theory were opplied to a controversial issue in a marketing context. Experimental factors were type of defense, time intervol between defense and attack, and credibility of the attacker. In general, predictions from inoculation theory were confirmed: all defenses conferred resistance to attack; the refutational defense was superior to the direct ...
