Giving too much social support: social overload on social networking sites

As the number of messages and social relationships embedded in social networking sites (SNS) increases, the amount of social information demanding a reaction from individuals increases as well. We observe that, as a consequence, SNS users feel they are giving too much social support to other SNS users. Drawing on social support theory (SST), we call this negative association with SNS usage ‘social overload’ and develop a latent variable to measure it. We then identify the theoretical antecedents and consequences of social overload and evaluate the social overload model empirically using interviews with 12 and a survey of 571 Facebook users. The results show that extent of usage, number of friends, subjective social support norms, and type of relationship (online-only vs offline friends) are factors that directly contribute to social overload while age has only an indirect effect. The psychological and behavioral consequences of social overload include feelings of SNS exhaustion by users, low levels of user satisfaction, and a high intention to reduce or even stop using SNS. The resulting theoretical implications for SST and SNS acceptance research are discussed and practical implications for organizations, SNS providers, and SNS users are drawn.     

Should I stay or should I go? The moderating effect of self-image congruity and trust on social networking continued use

Recent reports show that although users of large online social networks (such as Facebook) score low in terms of satisfaction, they manage to retain, or even increase, their user base. This study sheds an exploratory light on the reuse behaviour of online social network services (SNS). Specifically, we investigate the moderating effects of self-image congruity and trust on the relationship between satisfaction and continuance to use online SNS. To capture post-adoption behaviour of SNS users, we employ the expectation–confirmation model as a core structure for our theoretical model. The model is empirically tested using survey data collected from 288 Facebook users. Results reveal a possible trend suggesting that users perceiving a high match of the SNS with their self-image will be more loyal even if they experience low satisfaction levels. The same trend has been extracted for trust and its moderating effect on the relationship between satisfaction and usage continuance intention. This paper concludes with a discussion on the theoretical and practical implications of our findings.     

See you on Facebook: exploring influences on Facebook continuous usage

Facebook is a computer-mediated social network site (SNS) that has become a popular communication medium. Facebook permits individuals to construct a public profile within a bounded system, articulate a list of other users with whom they share a connection, and view their list of connections within the system. This study examines influences on Facebook continuous usage in Taiwan. An online survey was performed on a sample of 409 Facebook users. Structural equation models are used to examine hypotheses within the theoretical framework. Analytical results indicate that personal innovativeness, attachment motivation, and subjective norm (SN) positively affect perceived enjoyment (PE) and user attitude (ATT) towards Facebook. PE is positively related to user ATT. Furthermore, users are willing to continuously use Facebook when SN, PE, and user ATT are high.     

The Politeness of Requests Made Via Email and Voicemail: Support for the Hyperpersonal Model

This study analyzes requests made via email and voicemail for properties of politeness ( Brown & Levinson, 1987 ). Voicemail users have less control over planning, composing, editing, and executing messages, and must manage more nonverbal cues than email users. Thus, it is predicted that email will enable users to create more polite speech than voicemail. A 2 (communication medium: email or voicemail) x 2 (imposition: low or high) factorial design was implemented to test this hypothesis. One hundred fifty-one participants created request messages that were subsequently analyzed for properties of politeness. Overall, the results indicate email requests were more polite than voicemail requests. These results are consistent with the hyperpersonal model ( Walther, 1996 ) .     

Another brick in the Facebook wall – How personality traits relate to the content of status updates

Status updates represent a new form of one-to-many communication which is widely used among members of social networking sites (SNS). The present study investigated the question of who in particular uses the self-presentational opportunities of this feature and which users engage in riskier self-disclosures than others. Combining questionnaire and content analysis, we related self-reports on users’ personality traits (extraversion, narcissism, self-efficacy, need to belong, need for popularity) to the actual use of Facebook status updates. Results showed that higher degrees of narcissism led to deeper self-disclosures and more self-promotional content within these messages. Users with higher need to belong disclosed more intimate information in status updates, while perceived efficacy of self-presentation was negatively related to the mass suitability of postings. Findings extend prior research on personality and SNS usage with regard to dynamic features and content differences in online self-presentation.     

User adoption of social networking sites: Eliciting uses and gratifications through a means–end approach

This research examines users’ motives for adopting and using social networking sites (SNSs), with the aim of providing a better understanding of the fundamental reasons behind SNS adoption behavior. To uncover the relationship between the attributes of SNSs and users’ perceptions of their consequences and values, this study integrates a means–end approach with uses and gratifications theory and thereby extends the technique to a communication media selection context. Laddering interviews identify users’ perceptions of five attributes, 10 consequences, and four values associated with SNS adoption (i.e., Facebook). The results show that belonging, hedonism, self-esteem, and reciprocity are the four main values users attain through SNS adoption. Furthermore, the chains associated with SNS adoption can be represented in a hierarchical value map. This study should help practitioners design online communication platforms that more closely fit their users’ needs and provide users with safer, more friendly, and thus more attractive environments.     

Privacy-Aware Framework for Matching Online Social Identities in Multiple Social Networking Services

With various emerging Social Networking Services (SNS), it is possible for users to join multiple SNS for social relationships with other users and to collect a large amount of information (e.g., statuses on Facebook and tweets on Twitter). However, these users have been facing difficulties in managing all the data collected from the multiple SNS. It is important to match social identities from the multiple SNS. In this study, we propose a privacy-aware framework for a social identity matching (SIM) method across these multiple SNS. It means that the proposed approach can protect user privacy, because only the public information (e.g., username and the social relationships of the users) is employed to find the best matches between social identities. As a result, we have shown by evaluation that the F-measure of the proposed SIM method is about 60%.     

Assessing flow experience in social networking site based brand communities

The sustenance of the Social Networking Site (SNS)-based brand communities relies on user retention and their active participation. Therefore, understanding the intrinsic aspects of user behavior in such communities is important for devising strategies to ensure user retention and active participation. Especially, information about the elements that induce flow experiences—the intrinsically enjoyable and immersive experiences—of users in SNS has become important for organizations that host online communities. In our empirical study, we chose to focus especially on SNS-based brand communities, as they are increasingly interesting from an organization-community interaction perspective, but they lack the instruments needed for measuring user experience. The present study addresses this gap by developing an instrument aimed at measuring the user’s flow experience on SNS-based brand communities. A cross-sectional survey with 577 Facebook brand community users was carried out. The findings show that enjoyment, concentration, and social interaction are the components that constitute a user’s flow experience. In addition to providing a valuable tool for business practitioners, the developed instrument offers several theoretical and practical implications for improving user experience of social media.     

Understanding the Role of Conscious and Automatic Mechanisms in Social Networking Services: A Longitudinal Study

Given the proliferation of social networking sites (SNSs), it has become important to understand users’ continued attraction and usage of them. Previous works on information systems (IS) and marketing have paid little attention to the role of automatic mechanisms in frequently used IS such as mobile applications and SNSs. We develop an integrated framework to examine the effects of conscious and automatic mechanisms on SNS users’ postadoption behaviors. Considering the unique characteristics of SNSs, we posit user satisfaction, trust in an SNS provider, and prior SNS use as key drivers accelerating the development of SNS habitual use. Longitudinal data collected from 250 Facebook users were tested against the research model using partial least squares. The findings showed that SNS continuance usage is shaped by automatic factor as well as by reasoned conscious factor. In particular, SNS continuance usage is largely explained by SNS habit. User satisfaction, trust in an SNS provider, and prior SNS use were found to be the key enablers of developing SNS habit. Moreover, the analysis results clarify the exact role of relationship management, self-presentation, perceived enjoyment, and trust in an SNS provider in users’ decision-making processes. Implications for research and practice are described.

Facebook single and cross domain data for recommendation systems

The emergence of social networks and the vast amount of data that they contain about their users make them a valuable source for personal information about users for recommender systems. In this paper we investigate the feasibility and effectiveness of utilizing existing available data from social networks for the recommendation process, specifically from Facebook. The data may replace or enrich explicit user ratings. We extract from Facebook content published by users on their personal pages about their favorite items and preferences in the domain of recommendation, and data about preferences related to other domains to allow cross-domain recommendation. We study several methods for integrating Facebook data with the recommendation process and compare the performance of these methods with that of traditional collaborative filtering that utilizes user ratings. In a field study that we conducted, recommendations obtained using Facebook data were tested and compared for 95 subjects and their crawled Facebook friends. Encouraging results show that when data is sparse or not available for a new user, recommendation results relying solely on Facebook data are at least equally as accurate as results obtained from user ratings. The experimental study also indicates that enriching sparse rating data by adding Facebook data can significantly improve results. Moreover, our findings highlight the benefits of utilizing cross domain Facebook data to achieve improvement in recommendation performance.     

Persuasive Electronic Word-of-Mouth Messages in Social Media

Despite the influence of electronic word-of-mouth (eWOM) messages in decision-making processes, few studies have tested the determinants of persuasive eWOM messages among social media users. Although most of the researches focused on western and eastern cultural convergence or divergence of online communications, little attention has been paid on the validity and applicability of cultural orientations in countries with perceived inherent similar values. This study examines how Chinese and Malaysian users process eWOM messages and decide on continuing their overseas study. The significance of the study is to identify critical factors that influence Chinese and Malaysian users’ attitudes and behavior when processing persuasive eWOM messages. Results revealed that Facebook is the most used social networking site (SNS) for Malaysian users, while QQ Qzone for Chinese counterparts. This study found that argument quality, source credibility, source attractiveness, source perception, and source style exerted varying influences on Chinese and Malaysian users’ attitudes and intentions to continue their study abroad.     

An approach for temporal analysis of email data based on segmentation

Many kinds of information are hidden in email data, such as the information being exchanged, the time of exchange, and the user IDs participating in the exchange. Analyzing the email data can reveal valuable information about the social networks of a single user or multiple users, the topics being discussed, and so on. In this paper, we describe a novel approach for temporally analyzing the communication patterns embedded in email data based on time series segmentation. The approach computes egocentric communication patterns of a single user, as well as sociocentric communication patterns involving multiple users. Time series segmentation is used to uncover patterns that may span multiple time points and to study how these patterns change over time. To find egocentric patterns, the email communication of a user is represented as an item-set time series. An optimal segmentation of the item-set time series is constructed, from which patterns are extracted. To find sociocentric patterns, the email data is represented as an item-setgroup time series. Patterns involving multiple users are then extracted from an optimal segmentation of the item-setgroup time series. The proposed approach is applied to the Enron email data set, which produced very promising results.     

Meeting ex-partners on Facebook: users' anxiety and severity of depression

The purpose of the present study was to explore participants' subsequent emotions and behaviour when they re-encountered their ex-partners on Facebook. A survey of 202 Facebook users aged 16–65 years was conducted using a 79-question online survey to examine users' emotion and behaviour (state anxiety, trait anxiety, and severity of depression) when their ex-partners reappeared on social networking sites (SNS), they received an invitation from an ex-partner to be friends on SNS, and when they saw pictures of ex-partners with current girlfriends or boyfriends. The results indicated that for people who accepted former partners' invitation to be Facebook friends, trait anxiety was more pronounced than for those who did not. Moreover, people who accepted former partners' invitations to become Facebook friends were much more depressed than those who did not. In addition, it is found that gender generates significant differences in the severity of depression. It is worth noting that when people met former partners on Facebook, men were much more depressed than women. However, the way in which participants broke up with ex-partners did not significantly affect their state anxiety, trait anxiety, or the severity of depression. Finally, the participants' cognition of and importance placed on their former relationship resulted in significant differences in trait anxiety. The current study adds to the growing body of literature investigating relationships among SNS users, becoming friends with ex-partners on Facebook, emotions, and behaviour.     

Young adults’ use of communication technology within their romantic relationships and associations with attachment style

In an online survey with two cohorts (2009 and 2011) of undergraduates in dating relationships, we examined how attachment was related to communication technology use within romantic relationships. Participants reported on their attachment style and frequency of in-person communication as well as phone, text messaging, social network site (SNS), and electronic mail usage with partners. Texting and SNS communication were more frequent in 2011 than 2009. Attachment avoidance was related to less frequent phone use and texting, and greater email usage. Electronic communication channels (phone and texting) were related to positive relationship qualities, however, once accounting for attachment, only moderated effects were found. Interactions indicated texting was linked to more positive relationships for highly avoidant (but not less avoidant) participants. Additionally, email use was linked to more conflict for highly avoidant (but not less avoidant) participants. Finally, greater use of a SNS was positively associated with intimacy/support for those higher (but not lower) on attachment anxiety. This study illustrates how attachment can help to explain why the use of specific technology-based communication channels within romantic relationships may mean different things to different people, and that certain channels may be especially relevant in meeting insecurely attached individuals’ needs.     

Determinants of users’ continuance of social networking sites: A self-regulation perspective

Social networking sites (SNS) have transformed how individuals interact, build and maintain social relationships. We proposed a research model on the determinants of user continuance using Bagozzi's framework of self-regulation as the theoretical foundation. Following the process of appraisal → emotional reactions → coping responses, we developed the model by leveraging findings from social presence and IS continuance research. Based on survey data from Facebook users, we found that appraisal factors (pleasure, awareness, connectedness, and system quality) were strong determinants of emotional reaction (user satisfaction and sense of belonging). User satisfaction and sense of belonging together positively influenced continuance intention.     

To tweet or ‘subtweet’?: Impacts of social networking post directness and valence on interpersonal impressions

Subtweeting denotes using an SNS post to talk about another user behind his or her back in a public forum. This study investigates how others in the online environment view subtweeters and their messages. The experiment involved manipulating SNS posts in terms of directness of reference to another user (tweets versus subtweets) and valence of information (face-threatening versus face-giving messages). Results demonstrated that, overall, subtweets were perceived as lower in message competence, which led to less favorable interpersonal impressions of their sources. However, directness and valence interacted. Subtweeting led to less favorable impressions of face-giving posts, but more favorable impressions of face-threatening posts. Sources of direct, face-giving posts were rated most favorably. We present implications for Face Theory and politeness, and practical guidance for SNS users.     

Die Rolle der Kultur in der Selbstoffenbarung und Privatsph?re in sozialen Onlinenetzwerken

Social Network Sites (SNSs) rely exclusively on user-generated content to offer engaging and rewarding experience to its members. As a result, stimulating user communication and self-disclosure is vital for the sustainability of SNSs. However, considering that the SNS users are increasingly culturally diverse, motivating this audience to self-disclose requires understanding of their cultural intricacies. Yet existing research offers only limited insights into the role of culture behind the motivation of SNS users to self-disclose. Building on the privacy calculus framework, this study explores the role of two cultural dimensions ?C individualism and uncertainty avoidance ?C in self-disclosure decisions of SNS users. Survey responses of US and German Facebook members are used as the basis for our analysis. Structural equation modeling and multi-group analysis results reveal the distinct role of culture in the cognitive patterns of SNS users. The authors find that trusting beliefs play a key role in the self-disclosure decisions of users from individualistic cultures. At the same time, uncertainty avoidance determines the impact of privacy concerns. This paper contributes to the theory by rejecting the universal nature of privacy calculus processes. The findings provide for an array of managerial implications for SNS providers as they strive to encourage content creation and sharing by their heterogeneous members.     

社交网络用户标签预测研究

随着社交网站的流行以及用户的大规模增加,社交网络用户行为分析已经成为社交网站进行网站维护、性能优化和系统升级的重要基础,也是网络知识挖掘和信息检索的重要研究领域。为了更好地理解社交网络用户添加个人标签的行为特征,该文基于大约263万个微博用户的真实数据,对用户标签的分布进行了研究和分析。我们主要考察了用户标签的宏观分布特征,以及用户标签与关注对象的标签分布之间的联系,发现微博用户给自己添加标签时,在开始阶段倾向于使用反映个性的标签,之后会出于从众心理而选用大众化标签。我们将研究发现运用到基于关注关系的标签预测算法中,结果证实相关分析对于社交网站的标签推荐等课题具有一定的参考意义。     

Control your Facebook: An analysis of online privacy literacy

For an effective and responsible communication on social network sites (SNSs) users must decide between withholding and disclosing personal information. For this so-called privacy regulation, users need to have the respective skills—in other words, they need to have online privacy literacy. In this study, we discuss factors that potentially contribute to and result from online privacy literacy. In an online questionnaire with 630 Facebook users, we found that people who spend more time on Facebook and who have changed their privacy settings more frequently reported to have more online privacy literacy. People with more online privacy literacy, in turn, felt more secure on Facebook and implemented more social privacy settings. A mediation analysis showed that time spend on Facebook and experience with privacy regulation did not per se increase safety and privacy behavior directly, stressing the importance of online privacy literacy as a mediator to a safe and privacy-enhancing online behavior. We conclude that Internet experience leads to more online privacy literacy, which fosters a more cautious privacy behavior on SNSs.
