Cybercrime activities are supported by infrastructures and services originating from an underground economy. The current understanding of this phenomenon is that the cybercrime economy ought to be fraught with information asymmetry and adverse selection problems. They should make the effects that we observe every day impossible to sustain. In this paper, we show that the market structure and design...
This paper investigates the use of various user-driven methods in the development of public services. As an example, the paper presents a case where citizens and employees were brought together to identify development needs for remote-enabled public services. User-driven methods provided by a local Living Lab were used to solve the encountered challenges. The outcome of this study indicates that use...
Content replication and placement is an area that has been well explored in the scope of Content Delivery Networks (CDNs), but has received relatively less attention from the research community when it comes to Wireless Mesh Networks (WMNs). There are a number of Replica Placement Algorithms (RPAs) that are specifically designed for CDNs. But they do not consider the special features of wireless networks...
The increasing development of health social networks (HSN) in recent years has led the fast growing of user-generated contents. People tend to interact and share health information in social networks. However, the trustworthiness of information is the major concern in shared health information in social networks. Viral rumor-spreading that can happen quite rapidly in social media can cause damages...
Virtual community members' strong interactivity makes community information become an important factor that influence consumer decision-making. Based on the definition and dimensions of virtual community interactive content characteristics, we made an empirical research on the interactive content characteristics of C2C virtual community and its influence on users' network purchasing. The results show...
The aim of this paper is to provide a theoretical framework to analyze obstacles, challenges, and incentives which lead non-professional developers to design websites and produce information that are accessible to people with disabilities, and to describe the development of a reliable and validated instrument designed to test it. Results show that intrinsic motivation, self-efficacy, influence of...
Virtual Communities for Innovations (VCI) are becoming increasingly popular as platforms for firms to engage customers in generating new ideas. While several studies have explored the various motivations of user participation in VCI, the relationship between the motivations and the outcome of interest - the quality of the ideas - has not been explored. Scholars and practitioners have a strong interest...
In multi-agent recommender systems, agents are able to generate recommendations according to the preferences of the customer. However, in some domains, specific knowledge is required in order to compose a recommendation and this knowledge may be not available for the agent. In these cases, agents need to communicate with other agents in the community searching for the specific information to complete...
On the basis of extant literature, we built a conceptual model of the relationship among Perceived Quality, Perceived Value, Satisfaction, Sense of Belonging and Usage, and proposed some hypotheses about the influencing factors of continued system usage in SNS. To test the hypotheses, we designed a questionnaire, and conducted a survey in Xidian University. We used SPSS13.0 to analyze the collected...
This study investigates information cascades in knowledge sharing behavior in virtual communities. A research framework based on the social cognitive theory is developed to identify factors that would influence information cascades in knowledge sharing behavior in virtual communities. Structural Equation Modeling (SEM) is employed to test the hypotheses empirically. A survey involving a total of 213...
This paper focuses on the aspect of virtual community trust, combining the theory of Electronic word-of-mouth and Technology Acceptance Model, to develop a deeper understanding of how virtual communities influence consumer participation in online group-buying, and to extract the key factors that impact consumer willingness to participate in online group-buying. The research involves survey responses...
The virtual brand community (VBC) is a new brand phenomenon in Internet times. Drawing on social identity theory and the concept of the sense of community, this paper explores how the VBC impacts on consumer-based brand equity (CBBE) under the mediating effects of consumer participation, and puts forward some suggestions about building the VBC to enhance the CBBE.
Internet became the main platform for exchange of views on product and word of mouth. In this paper, we define the online seller's commercial policy reasonableness, website quality, product value as the independent variables, the online trust (online trust beliefs and online trust intentions) as an intermediary variable, to explore the formation mechanism and influence of EWOM Communications.
On the basis of extant literatures, we built a conceptual model of the relationship between perceived quality, trust, extrinsic motivation, intrinsic motivation and usage in the virtual communities with real-name system, and proposed some hypotheses about them. To test the hypotheses, we designed a questionnaire, and collected data from the members who use virtual communities with real-name system...
This paper proposes an application of low cost IPv6 based wireless sensor network in distributed generation. The wireless sensor network used in the proposed scheme is based on IEEE 802.15.4 link layer technology and the sensor nodes have the ability to communicate directly with other IP devices via internet. A web based service is appreciated for implementing the proposed smart power distribution...
This paper intends to gather some evidences on how sponsorship effectiveness is positively or negatively affected by the choice of focusing on niche communities (the Long Tail Communities), i.e. whether in niche communities there are differences in the members' brand perception between online and offline sponsors. The preliminary results demonstrate how the explanatory power of the involved variables...
Since the explosion and popularity of Internet, virtual brand community has been serving as a new and important brand experience centre for consumers to acquire necessary brand and product knowledge. Based on the empirical literature and the nature of online shopping, this study proposed a series of research hypotheses and a theoretical model. Internet shoppers' brand experience (sensory, affective,...
In perspective of the sustainable growth for the online community, the paper firstly proposed the practical significance of brand strategy implementation for online community, then designed the brand value creation process model of online community based on consumer's participation, and elaborated each process, finally, it took an online community as example, for demonstrating the creation process...
Trust is generally based on the level and quality of interaction with the entity being trusted. In a web service or the Internet, trust is based on the level of successful and unsuccessful interactions. Successful interactions are used to model trust within the context of chains of trust in which an agent is permitted to recommend a service. This is termed trust chain since the agent need to first...
The development of information technology improves the globalization of the world economy. This change was able to expand the cyber space, and the online community known as the cyber community is made within the existing offline community. From the cyber community's activity, the concept of social network services created, and recently developed social computing. Social computing is the current situation...
