The purpose of this paper is to develop a research framework by drawing on the network externalities research and previous literature on information systems to understand the antecedents of information disclosure. The framework postulates that the following network externalities are important factors affecting social network sites (SNS) perceived usefulness (PU): perceived external prestige, referent network size and perceived complementarity. In addition, the paper proposes that PU, habit and subjective norms significantly affect information disclosure of SNS among Chinese users.

Data are collected from 251 Chinese university students who use SNS. Structural equation modeling was applied to test the hypotheses presented in the model.

The findings provide support for all the hypotheses, with the exception of the influence of referent network size on PU and the influence of subjective norms on information disclosure. Both perceived external prestige and perceived complementarity have reported positive effect on PU of SNS. In turn, the authors have found that PU and habit have positive effects on information disclosure.

SNS encourage users to reveal personal information by allowing them to post photos and videos and share their interests and feelings on the site. Yet, limited empirical research has investigated the concept of self-disclosure of personal information particularly among Chinese users of SNS. To fill this research gap, the authors have developed a research framework by drawing on the network externalities research and previous literature on information systems to understand the antecedents of information disclosure.

The purpose of this paper is to asses the role of social networking sites (SNSs) in the 25 January 2011 Egyptian Revolution, also known as the “Arab Spring”.

The research methods used were an adaptive form of snowball sampling of a heterogeneous demographic group of participants in the Revolution, used to select focus groups to explore a range of relevant issues.

SNSs are shown to have played a central and pivotal role in the events known collectively as the Arab Spring. Their importance as a source of non‐governmental information and as a means of informing the external and internal community of internal events is highlighted by all participants.

The paper outlines research into contemporary events of global significance.

Social networking sites (SNS) have become popular destinations for college students all over the world. The minds of the college students have been steadily taking over by the influence of social networking, and this can impact their ability for doing research. Against this backdrop, this paper aims to investigate the role of SNS in enhancing the research activities of the degree college students in the Srinagar district of Kashmir, J&K, India.

A survey method was used to conduct the study, and Cochran’s sampling formula was applied to select the sampling size. Data were collected with the aid of a well-designed and structured questionnaire using Google forms. Besides, the focus group discussions were conducted to get varied opinions.

The findings revealed that the majority of the students agree or strongly agree that SNS help them in interacting with researchers, reading research content, keeping them abreast of research articles, knowing research trends, developing research aptitude and facilitating logical thinking and reasoning. The study confirmed that SNS help in enhancing the research traits of college students. However, students have been cautioned to make proper and judicious use of SNS.

The study is limited to the college students of Srinagar, Jammu and Kashmir (India), and the results cannot be generalised across regions and countries.

To the best of the authors’ knowledge, the study, being a part of PhD programme, is the original work of great value. It investigates the role of SNS in enhancing the research traits of college students and brings into light various hidden facts.

The purpose of this paper is to explore the determinants of continuance intention of social networking site (SNS) users through a new perspective and discuss how to retain SNS users.

The author proposed a research model by integrating network externalities and social support. Three dimensions of social support and two types of network externalities were analyzed, respectively, to explore the direct and indirect effects on continuance intention. Online questionnaires were adopted to collect data, and 513 valid samples were analyzed by structural equation modeling approach.

The findings show that network externalities have a significant indirect effect on user’ continuance intention through the mediation effects of social support, and among the three dimensions of social support, network management plays a more important role on continuance intention.

The findings suggest that network externalities can trigger the function of social support to keep the “stickiness” of SNS users, and network management is the key dimension of online social support. Some other theoretical and practical implications are also provided.

The study is novel in exploring users’ continuance intention of SNSs by integrating social support and network externalities. Meanwhile, the author also intends to compare the effect of different dimensions of social support on SNS usage and discuss their internal relationships.

This paper aims to assess information technology (IT) managers' perception of the strengths, weaknesses, opportunities and threats (SWOT) of using social networking sites (SNS) for group work at government organizations. According to the research, SNS provide considerable potential and can be a valuable technology for group work in government, public and/or non-profit organizations.

This study adopted a Delphi technique to assess the SWOT from IT managers in government organizations in Oman, a developing Middle Eastern country. One of the main roles of IT managers is to develop a short-term and long-term IT strategy, and identify opportunities in new technologies. SWOT analysis is a very useful tool to strategically analyze and understand an organization's current position in any IT deployment. As an exploratory study, Delphi technique is utilized as it produces the most reliable consensus of a group of experts. Data was collected through a web-based questionnaire.

The results suggest that there are more strengths than weaknesses and more opportunities than threats. However, some weaknesses and risks are critical as they relate to security and privacy controls and breaches. The study illustrates IT managers' perception about the use of SNS in government organizations.

For government organizations, prior research was mainly on the use of SNS to improve communication between government organizations and citizens. Not much is known about organizations' use of public technologies for a challenging process such as group collaboration. Results can be utilized by researchers and practitioners to improve SNS use for group work and to raise organizations' and individuals' awareness about implementing some controls that eliminate the critical threats. Results also can be utilized by IT policy and strategy makers in Oman and government organizations to develop overall national policy and guidelines for the use of SNS by government organizations.

The purpose of this paper is to explore and examine the different word-of-mouth (WOM) acceptance and diffusion in social brand communities according to the level of self-monitoring.

A web-based experimental design was used. The design consisted of three-mixed design of 2 (type of social networking sites) × 2 (type of online brand communities) × 2 (self-monitoring). ANOVA analysis was conducted.

Findings indicate that the differences in acceptance and diffusion of WOM according to online brand community type, and there was a significant three-way interaction effect. Specifically, people who have high propensity to self-monitor showed greater WOM acceptance in a consumer-driven community in either type of social networking sites while people who have low propensity to self-monitor showed greater WOM diffusion in a consumer-driven community only in interest-based social networking sites.

An important implication is that the social networking sites where brand communities can be placed should be chosen with the full consideration of different desires consumers have in terms of their level of self-monitoring to increase WOM effects.

This paper proposes the self-monitoring tendency as the key factor that predicts WOM effects with revealing the optimal combination of types of social networking sites and online brand communities that is most preferable for consumers with different self-monitoring level.

As social network sites (SNS) have increasingly become one of the most important channels for communication, the related privacy issues gain more and more attention in both industry and academic research fields. This study aims to connect the antecedents of information privacy disclosure on SNS.

Based on exchange theory, this study tries to investigate the decision-making process for information privacy disclosure on SNS. Factors from both user’s and website’s perspectives are taken into account in the proposed model.

The results suggest that an individual’s perceived benefits will increase their willingness to disclose information privacy on SNS, but perceived risks decrease this kind of willingness. The authors also find social network size, personal innovativeness and incentive provision positively affect people’s perceived benefits.

Moreover, privacy invasion experience enhances perceived personal risks, but website reputation helps to reduce perceived risks.

The purpose of this paper is to conduct a systematic review of studies that have used the technology acceptance model (TAM) in the context of social network sites (SNS). It describes various studies undertaken to examine user behaviours and attitudes towards SNS.

This paper comprehensively reviews the selected literature associated with applications of TAM in the SNS context. Different studies conducted within the SNS context were evaluated for understanding the changes incorporated into the model.

The findings illustrated that the TAM has been successfully applied via its extension and modification for explaining user adoption and acceptance of SNS.

The study contributes to the theoretical novelty of the body of the existing literature in the domains of TAM and SNS. The study also provides insight on future research directions by helping in identifying gaps in literature in this field.

User trust in social networking sites (SNS) has become an important issue in SNS discussions. This is because of its impact on knowledge sharing, social commerce, social interaction, among many others. However, information systems researchers have primarily explored the benefits of trust with little attention to its antecedents. In an attempt to address this knowledge gap, this study proposed a model that investigated the factors that promote trust among SNS users. Data was gathered from voluntary respondents using a questionnaire. A PLS-SEM analysis of 912 valid responses suggested that Norm of Reciprocity, Social Interaction Ties and Identification are significant factors that encourage Trust among SNS users. Shared Language was also identified to have impact on Norm of Reciprocity, Social Interaction Ties and Identification. The results of the study provide significant theoretical and practical contributions. They bridge the knowledge gap regarding the formation of Trust on SNS. The model evaluated explains 49.6% of the variance in Trust and thus suitable for analyzing the antecedents of Trust on SNS. Furthermore, with the significance of Identification, Social Interaction Ties and Norm of Reciprocity on Trust, SNS developers are tasked to offer SNS features that proliferate the formation of these factors as well as shared interpretations.

Social distancing is an important strategy to control the spread of the COVID-19 pandemic, so it is imperative to understand the behavioral impact of social distancing on individuals. This research studied social distancing from a cognitive appraisal of voluntary social distancing compliance (CAVSD) point of view and a non-medical perspective, specifically the psychological impact (PI) of social distancing on the usage intensity of social networking sites (SNS) during the COVID-19 outbreak in India.

The study was conducted on 477 SNS users as a full sample and groups based on age, sex and work status. The model was empirically investigated using structural equation modeling.

CAVSD was negatively associated with PI although it was not a significant predictor, while CAVSD and PI were significant predictors of SNS usage intensity; moreover, SNS usage intensity differed between groups of people.

These findings are significant for organizations, corporations and educational institutions in both the public and private sectors. There is a need to identify subsections of individuals in need of social support and relief from isolation and loneliness. Individuals are relying on social media to handle social distancing and the pandemic, and this shows up in an increase in social networking activity.

This study contributes to the existing literature by positing social networking as a basic virtual need for socialization, and social media platform assists in that. Cognitive appraisal is an important determinant of individual response.
