When Online Dating Partners Meet Offline: The Effect of Modality Switching on Relational Communication Between Online Daters

Despite the popularity of online dating sites, little is known about what occurs when online dating partners choose to communicate offline. Drawing upon the modality switching perspective, the present study assessed a national sample of online daters to determine whether face‐to‐face (FtF) relational outcomes could be predicted by the amount of online communication prior to the initial FtF meeting. Results were consistent with the hypothesized curvilinear relationship between the amount of online communication and perceptions of relational messages (intimacy, composure, informality, social orientation), forecasts of the future of the relationship, and information seeking behavior when meeting their partner FtF. The results provide support for the modality switching perspective, and offer important insight for online daters.     

Community engagement and online word of mouth: An empirical investigation

How customer engagement in a firm’s social media marketing platform ? online brand community ? might affect word-of-mouth behavior is an open research issue as well as a vital business problem in e-commerce. To this end, we collected a set of longitudinal data that include community engagement behavior, e-commerce transactions, and customers’ post-purchase reviews. Using a control function approach, we find that consumer engagement in a brand community not only increases the likelihood of generating post-purchase reviews but also increases the likelihood of posting positive online reviews. Furthermore, we find that customer tenure has a positive moderating effect.

Enhancing Online Community Activity: Development and validation of the CA framework

Factors contributing to development of active communities are identified and combined into the Community Activity framework, which is useful in setting up new, or revitalizing inactive, communities. Found factors include: notifying members of new messages by e-mail, having a news section, and ability to add pictures to member profiles. During application of the framework to an inactive community, changes have been made to privacy options, polls, activity notifications, and other areas. Significant positive effects have been found in the number of visits, volume of posted messages, and number of topics. Interest of community members in both user profiles and the message board increased significantly. We conclude that the Community Activity framework is able to contribute in developing active online communities.     

Strategic self-presentation on Facebook: Personal motives and audience response to online behavior

People have always been concerned with their social image and engaged in strategic self-presentation (Goffman, 1959), but the growth of social networking sites (SNS) has had a major influence on such social endeavors. When people choose how to present themselves online, they use strategies and make choices that influence the liking and respect they receive from others. We examine a model that links: (a) motives for self-presentation, (b) actual online behavior on Facebook, and (c) feedback: social network members' responses (“likes,” comments). One hundred and fifty-six undergraduates (37 males, 119 females, mean age = 24.5) reported on their last three Facebook status updates (468 status updates overall). Based on structural equation modeling, we found that performance goals predict increased levels of self-enhancement on Facebook and increased levels of social feedback – “likes” and comments by others. Mastery goals do not predict increased levels of self-derogation (posting negative contents about self), but those who do choose to derogate also receive increased numbers of “likes” and comments from their network friends.

Face off: Implications of visual cues on initiating friendship on Facebook

This research investigates how moderating factors and theoretically relevant contextual variables affect impression formation and the willingness to initiate virtual friendship. An experiment examined both main and interaction effects for visual cues, profile owner’s gender, and evaluator’s gender; a 2 (stimulus gender: male and female) × 3 (visual conditions: attractive, unattractive, and no-photo) × 2 (evaluator’s gender: male and female) between subjects model analysis of variance (ANOVA) was employed. A three-way interaction between gender and appearance was revealed. The results indicated that both male and female subjects were more willing to initiate friendships with opposite-sex profile owners with attractive photos. Subjects also displayed comparatively higher willingness to make friends with profile owners who did not include visual cues than with those who revealed an unattractive photo. The hyperpersonal model was supported and extended to address gender attributes.     

Negative emotional and cognitive responses to being unfriended on Facebook: An exploratory study

We consider Facebook unfriending as a form of relationship termination with negative emotional and cognitive consequences. Specifically, ruminative and negative emotional responses are examined via an online survey of adult Facebook users who were unfriended. These responses were positively related to each other and to Facebook intensity. Rumination was positively predicted by using Facebook to connect with existing contacts and was more likely when the unfriender was a close partner. Participants also responded with greater rumination and negative emotion when they knew who unfriended them, when they thought they were unfriended for Facebook-related reasons, and when participants initiated the Facebook friend request. The contribution of these exploratory findings to our growing understanding of negative relational behaviors on Facebook are discussed.     

Extent of private information disclosure on online social networks: An exploration of Facebook mobile phone users

The present study adopts the Communication Privacy Management theory and investigates the factors that influence the extent of private information disclosure of Facebook mobile phone users. Using a sample size of 488 adult mobile phone users, the study further investigates the differential impact of age on the extent of private information disclosure. Results from the logistic regressions run reveal that use of smartphones to access social networking sites, use of multiple social networks, and being female decrease the likelihood of private information disclosure. In addition, usability problems increase the likelihood of information disclosure by older adults. The analyses show no association between perceived benefit and private information disclosure.     

The impact of the online and offline features on the user acceptance of Internet shopping malls

Internet shopping mall has the dual nature of Web-based application system and traditional shopping mall. This paper explores online and offline features of Internet shopping malls and their relationships with the acceptance behaviors of customers. The results from a Web survey of 932 users show that the technology acceptance model (TAM) is valid in predicting the acceptance of the Internet shopping malls and that online and offline features have positive effects on the user acceptance. Both online and offline features have greater effects on the usefulness, attitude, and intention to use than either online or offline features separately. This study provides a domain-specific, integrative approach in evaluating the quality and antecedents of user acceptance for Internet shopping malls.

Disclosures about important life events on Facebook: Relationships with stress and quality of life

The current study examined the relationship between general perceived levels of stress, quality of life, social networking usage, and disclosing important life events on Facebook in order to better understand the complex relationship between online disclosure and individual well-being. An online survey was completed by adult Facebook users aged 18–70. Results indicate that the more time spent on and the more social network memberships, the higher stress and lower quality of life; Facebook-specific usage was unrelated to either well-being variable. Together, these findings suggest that the current increase in social media variety and usage may be detrimental to user well-being. Users who shared important, bad health news on Facebook had higher stress and lower quality of life than those who did not, with no significant differences for sharing good health news. The more that users did not share important news on Facebook for self-protection and friend unresponsiveness reasons, the greater their stress. The self-protection reason was also negatively related to quality of life. These inconsistent findings can likely be partially explained by the nature of the information that is shared. These findings are discussed in light of disclosure and relationship patterns on social networks.     

Online stickiness: its antecedents and effect on purchasing intention

Website stickiness, the website's ability to retain online customers and prolong his/her duration of each stay, is one of the key factors to e-commerce success. However, how to make customers stick around is still unclear to online retailers. This paper examines the antecedents as well as effect of customer's intention to stick on a website. A model is developed and tested using a survey of 434 web users. The results confirm that the web user's willingness to stick to a website is a strong predictor of his/her intention to transact. Web managers thus need to put emphasis on the creation of the website stickiness. The results of this study also suggest that the formation of the stickiness is affected by web user attitude towards a website, trust in a website and the quality of website content. Implications of these findings are discussed for researchers and practitioners.
