Positive and negative aspects of online community cultivation: Implications for online stores’ relationship management

We investigated how online community building might affect the development of relationships with customers of online stores. Adopting social identification and relationship marketing perspectives, we examined the positive and negative aspects of online community cultivation and tested the meditating mechanisms involved in member participation processes. A survey-based study, conducted with 913 online consumers, revealed that community interaction can lead to consumer power through community identification and relationship investments. Furthermore, we found that perceived e-tailer support negatively affected the relationship between identification and consumer power. We concluded with a discussion of the key managerial and research implications of our findings.     

Not all posts are treated equal: An empirical investigation of post replying behavior in an online travel community

The post replying behavior in online communities (OCs) has garnered little consideration, even though the feedback behavior represents the central social dynamic of OCs and greatly determines the vibrancy of OCs. To fill this gap, this study aims to identify major sharing post-related variables that explain the heterogeneity in the post replying behavior in knowledge sharing OCs. The research model is validated through a panel dataset assembled from an online travel community. The results reveal that sharing post length and vividness, contributors’ expertise and degree centrality, and members’ social interactions have significant associations with the number of replying posts.     

Non-public and public online community participation: Needs, attitudes and behavior

Nonpublic participation within an online community, often called lurking, occurs when an individual joins a community, but does not post. This study examines the nature of lurking, why people lurk and the differences in attitudes between lurkers and posters. The results indicate significant differences between people who lurk and those who post in an online community. We conclude that when people lurk they are observing, which in no way is a negative behavior. This introverted or passive behavior affects lurkers' attitudes about the benefits of the community, their expectations, and opinions of themselves and others who lurk. In general lurkers are less optimistic and less positive than those who post.

Mediating roles of self-presentation desire in online game community commitment and trust behavior of Massive Multiplayer Online Role-Playing Games

Massive Multiplayer Online Role-Playing Games (MMORPGs), which allow simultaneous participation of several gamers, have attracted a great deal of attention recently. Since MMORPGs can be categorized as a type of online community, the behavior of MMORPGs users needs to be considered as the general behavior in online communities. However, previous studies of online communities did not pay enough attention to MMORPGs, in which users can express themselves by interacting actively through games and game avatars. Understanding the characteristics of MMORPGs as online game communities where users communicate and interact will allow games to be vitalized and users to be immersed in games in a more positive way. Hence, using self-presentation theory and social identity theory, this study examined the factors influencing self-presentation desire and the mediating role of self-presentation desire examined in terms of trust of and commitments to online game communities. The results showed that the interactivity in the spaces of MMORPGs had the biggest impacts on self-presentation desire; personal innovativeness and game design quality also was influential. The results also indicated that self-presentation desire caused trust of online games and eventually led to even stronger commitments to gamers.     

The CSCL community in its first decade: development, continuity, connectivity

Ten years of international CSCL conferences (1995–2005) provide an occasion to reflect on the formation of the CSCL community. Based on quantitative analysis of conference proceedings, lists of participants and program committee members, and on qualitative study of policies and motives, this paper offers insights into the growth of the CSCL community in its first decade. The analysis focuses on participation at different levels of the community. In particular, focus is on the continuity of active and passive membership, the geographical distribution, and the international connectivity of the community. Contrary to expectations, only a relatively small number of people have participated continuously in the community. Concerning the geographical distribution, we found that the community is increasingly international in conference participation, authors, and program committees. The international connectivity of the community is also increasing, which can be seen in a growing number of citations and co-authorships across different countries. In order to interpret the results of our quantitative study, we conducted a qualitative, e-mail-based survey. In this survey we wanted to elaborate the policy of the conference organization, the reasons for international co-authorships and the motivations for participation in CSCL conferences. We contacted 84 members of different target groups (organizers, members of international co-authorships, and randomly selected participants on different levels of participation). The findings are suggestive for the further development of the CSCL community.     

Perspectives on the evolution of online communities

The rapid growth of social networks opens interesting research opportunities to make use of the massive information exchanged in day-to-day communication. One of the active research issues related to this aspect is the study of online community formation and evolution in dynamic social networks. As community structure is usually ambiguous, then defining how it evolves over time becomes a challenge in terms of tracking mechanism and evaluation method. In this study, we review the online communities and their evolution tracking mechanisms and discuss the main categories of approaches for tracking community evolution and how they work. We analyse the different solutions proposed under each community evolution tracking category and provide an assessment of their projected performance. Finally, a discussion of analysis insights concerning community evolution and its influence is introduced.     

The role of message-sequences in the sustainability of an online support community for older people

This article presents an investigation of an online support community for older people, analyzing a data-set of messages posted over the period of six years. We studied messages that are related to each other which we call "message-sequences". We investigated the content of message-sequences and linked our findings to the level of activity of the online support community over time. We show how certain sequences of messages within the online community are related to the level of activity thus providing valuable insight into the role of message-sequences in sustaining online support communities for older people. We conclude that the mutual exchange of personal information and receiving support after talking about personal problems are basic components for the sustainability of the online community, whereas conversations that go off the topic of the online community seem to be related to a decrease in the level of activity.     

Community of inquiry as a theoretical framework to foster “epistemic engagement” and “cognitive presence” in online education

In this paper, several recent theoretical conceptions of technology-mediated education are examined and a study of 2159 online learners is presented. The study validates an instrument designed to measure teaching, social, and cognitive presence indicative of a community of learners within the community of inquiry (CoI) framework [Garrison, D. R., Anderson, T., & Archer, W. (2000). Critical inquiry in a text-based environment: Computer conferencing in higher education. The Internet and Higher Education, 2, 1–19; Garrison, D. R., Anderson, T., & Archer, W. (2001). Critical thinking, cognitive presence, and computer conferencing in distance education. American Journal of Distance Education, 15(1), 7–23]. Results indicate that the survey items cohere into interpretable factors that represent the intended constructs. Further it was determined through structural equation modeling that 70% of the variance in the online students’ levels of cognitive presence, a multivariate measure of learning, can be modeled based on their reports of their instructors’ skills in fostering teaching presence and their own abilities to establish a sense of social presence. Additional analysis identifies more details of the relationship between learner understandings of teaching and social presence and its impact on their cognitive presence. Implications for online teaching, policy, and faculty development are discussed.

How virtual community participation influences consumer loyalty intentions in online shopping contexts: an investigation of mediating factors

Extant studies generally recognise that virtual community building is an effective marketing programme for forging deep and enduring affective bonds with consumers. This study extends previous research by proposing and testing a model that investigates key mediating processes (via trust, satisfaction and identification) that underlie the relationship between virtual community participation and consumer loyalty intentions. The authors test the hypotheses using data obtained from three large online retailing stores. Virtual community participation significantly enhances loyalty intentions, through both social mechanisms (via community identification) and psychological mechanisms (via trust and satisfaction). Moreover, the findings provide insights into the complex relationship between the two mechanisms in online shopping settings. Community identification is a pivotal factor for enhancing customer loyalty intentions. The results advance understanding of the process by which virtual community building facilitates the development of business-to-consumer relationships in the computer-mediated environment. The authors discuss the managerial implications of the findings, as well as avenues for further research.     

A longitudinal study of leader influence in sustaining an online community

Previous research suggests that online leaders play an important role in sustaining community activities. Although the research has contributed to our understanding of how leaders develop effective ways to operate a community, most only provide a snapshot view of online leadership, thus paying little attention to changes in leaders in a communal context. In this study, we adopt the theory of networked influence to investigate the dynamics of online leadership using a longitudinal analysis. Data were collected from an online community in operation for 10 years. By conducting social network analysis using qualitative methods, we identified several types of emerging and coexisting online leadership, i.e., responsive expert leader, multiboard connectors, and social bond leader. The community’s sustainability did not rely on the same leaders throughout its temporal development but rather a “relay event” involving passing on the baton among different leaders with their specific leadership styles, which had a significant positive impact on the sustainability of user participation.     

ICSSSS: An intelligent channel selection scheme for cognitive radio ad hoc networks using a self organized map followed by simple segregation

In Cognitive Radio Ad Hoc Networks (CRAHNS), several spectrum bands with different channel characteristics may be available over a large frequency range. It is essential to identify the most appropriate spectrum band correctly which allow the Secondary Users (SUs) to exploit the band without disturbing the Primary Users (PUs). Many channel selection solutions, based on cooperative spectrum sensing, have been employed for this purpose depending on their prediction models for primary users’ activities. In practice, cooperative spectrum sensing cannot completely solve the sensing problems which are false alarm and miss detection, especially in heavily shadowed or fading environment. This paper presents, ICSSSS, as an Intelligent Channel Selection Scheme for cognitive radio ad hoc network using Self organized map followed by simple Segregation. The contribution of the proposed scheme is twofold: using an unsupervised learnable Self Organizing Map (SOM) method to efficiently minimize the probability of the sensing errors (false alarm and miss detection), in addition to segregated channel selection strategy to speed up the search for the available best channel. Simulation results based on NS2 simulations show that the proposed scheme can be used with the advantage of better performance than other existing channel selection strategies.     

Behavioral simulation and optimization of generation companies in electricity markets by fuzzy cognitive map

Simulation can be used in a wide range of applications in an electricity market. There are many reasons that market players and regulators are very interested in anticipating the behavior of the market. Behavior of a generation company (GENCO) in electricity market is an important factor that affects the market behavior. Several factors affect the behavior of a GENCO directly and indirectly. In this study, a new approach based on fuzzy cognitive map (FCM) is introduced to model and simulate GENCO’s behavior in the electricity market with respect to profit maximization. FCM helps the decision makers to understand the complex dynamics between a certain strategic goal and the related factors. This paper examines how effective factors affect on a GENCO’s profit. To identify key factors relevant to the goal, a FCM is built and then analyzed. To analyze this problem, two cases as simple FCM and weighted FCM are considered. Simple FCM shows how the determined factors affect on goal. A hidden pattern is obtained by this case. Weighted FCM helps sensitivity analysis of the model. In addition, the weighted FCM is used usefully to clearly measure the composite effects resulting from changes of multiple factors. This application is shown by two different case studies. This is the first study that models and simulates the behavior of GENCO in electricity market with respect to profit maximization.     

Interactive effects of individual- and group-level variables on virtual purchase behavior in online communities

Focusing on social network theories, we examine the interactive influence of both group-level (i.e. community influences) and individual-level variables (intrinsic and extrinsic motivations) simultaneously as the drivers of Massively Multiplayer Online Role-Playing Game (MMORPG) players’ virtual purchase behavior. We demonstrate that several aspects of real-world behavior are reflected in virtual purchase behavior. Notably, normative interpersonal influences and community identity are critical drivers and moderators of virtual purchases. Moreover, clear advancement and enjoyment opportunities offer important triggers for virtual purchase behavior. This study provides insights for game developers to increase virtual purchases, and identifies domain-specificity of each gaming platform.     

Reciprocity norms and information-sharing behavior in online consumption communities: An empirical investigation of antecedents and moderators

This study seeks a better understanding of information-sharing behavior in online consumption communities by investigating both the antecedents and moderating mechanisms of such behavior. Using self-reported data collected over two periods, along with objective behavioral data, the authors show that a reciprocity norm functions as a proximal determinant of information-sharing behavior. This norm also channels the effects of social, hedonic, and utilitarian community values on sharing behavior. The results reveal that the conversion of reciprocity norms into information-sharing behavior depends on individual and contextual conditions. These significant insights reflect the integration of consumer resource allocation theory with a reciprocity framework to establish an explanatory platform for members’ information-sharing behavior in online communities. Both theoretical and practical implications are discussed.     

Forward–backward analysis of RFID-enabled supply chain using fuzzy cognitive map and genetic algorithm

Supply chain is a non-deterministic system in which uncontrollable external states with probabilistic behaviors (e.g., machine failure rate) influence on internal states (e.g., inventory level) significantly through complex causal relationships. Thanks to Radio frequency identification (RFID) technology, real time monitoring of the states is now possible. The current research on processing RFID data is, however, limited to statistical information. The goal of this research is to mine bidirectional cause-effect knowledge from the state data. In detail, fuzzy cognitive map (FCM) model of supply chain is developed. By using genetic algorithm, the weight matrix of the FCM model is discovered with the past state data, and forward (what-if) analysis is performed. Also, when sudden change in a certain state is detected, its cause is sought from the past state data throughout backward analysis. Simulation based experiments are provided to show the performance of the proposed forward–backward analysis methodology.     

Networking relations of using ICT within a teacher community

The purpose of the present study was to examine the network structure of a teacher community in relation to their use of information and communication technology (ICT). The participants in the study were the 33 members of the teacher community of an upper comprehensive school from a suburban area of Helsinki, Finland. The methodology of the study was social network analysis. The participants were asked to assess their networking relations according to the following five dimensions: (1) providing technical advice regarding ICT, (2) providing pedagogical advice for using ICT, (3) collaboration regarding web-based learning, (4) acquiring new knowledge or ideas of web-based learning, and (5) informal interaction between the members of the community. The results indicated that there were a few central actors in the community who dominated technical and pedagogical knowledge exchange and to whom their colleagues actively turned when seeking advice. Two of the cognitively central actors represented hybrid expertise, a characteristic of which was to merge technological and pedagogical expertise in using ICT in education. These actors also tended to have their own external networking relations that helped them keep up their high level of competence. The participants’ ICT-related egocentric networks differed in size and density. There were some actors central in the network of informal interaction that were, simultaneously, peripheral in ICT-related networking activities. On the other hand, the central actors of ICT were not necessarily the socially central persons in the community. Four patterns of networking were identified in the analysis; The Counsellor offers advice actively without seeking information herself from colleagues; The Inquirer is an active seeker of ICT-related information capitalizing on her social relations; The Collaborator engages in collaborative efforts of web-based learning by using several media; and The Weakly Social prefers media rather than face-to-face contacts in his information seeking.
