  • Examining the Role of Perceived Social Benefit and Trust Matter in Sustainability of Online Social Networking Community - Social Exchange Theory Perspective   Order a copy of this article
    by Soo Il Shin, Kyung Young Lee, Dianne J. Hall 
    Abstract: Based on social exchange theory (SET), the current study examines how perceived social benefit from social networking community (SNC) activities influences community members’ affective commitment to the SNC via satisfaction. Additionally, we investigated how SNC members’ trust defined as securing personal privacy and information in the community moderates the relationships between satisfaction and affective commitment. Analysing survey data collected from Facebook users, our findings reveal that SNC members’ perceived social benefit and trust play salient roles in explaining members’ affective commitment to SNCs. Moreover, trust plays an important role in moderating the relationships between SNC members’ perceptions. The current study contributes to the body of knowledge on social networking, web-based communities and social exchange theory literature. Detailed implications and limitations are discussed.

  • MEDIATING ROLE OF SOCIAL SUPPORT ON THE RELATIONSHIP BETWEEN SOCIAL COMMERCE CONSTRUCTS AND BUYERS’ TRUST   Order a copy of this article
    by Priyanka Sharma, Sandeep Singh, Rajni Bala, Shafique Ur Rehman 
    Abstract: The social association of the buyers on the web contributes in shaping the social commerce. This study aims to measure the relationship between social commerce constructs, social support (SS) and perceived trust. The sample of the study was constituted of 289 social networking website users selected from northern India. The information regarding social commerce constructs, trust and intention to buy was collected by applying three standardised scales. Partial least square structural equation modelling (PLS-SEM) was used to analyse the data. The results showed that social commerce constructs had a significant impact on social support, while social support exercised a significant effect on trust. The results also confirmed the partial mediation effect of social support. The tested research model can be utilised in the advancement of brand, new products, co-invention of value for branding, and pre-testing any idea of product development on social networking websites.

  • The More I Open Up, the More You "Like" Me: Self-Disclosure and Intimacy Predict Engagement in Women's Facebook Groups   Order a copy of this article
    by Dana Weimann Saks, Yaron Ariel, Vered Elishar-Malka 
    Abstract: The current research focuses on two closed Facebook groups founded and operated by women, and targets an exclusively female audience with over 100,000 members in each. By analysing 433 posts from one group (study 1), and 1,070 from another (study 2), this paper identified the relationships between levels of self-disclosure expressed in members’ posts, levels of intimacy regarding the topics discussed, and the scale and nature of engagement with these posts. Findings indicate a positive correlation between self-disclosure in the posts and engagement with the posts. This correlation was evident mainly in personal topics. In this sense, closed women’s groups on Facebook have the power to enrich users’ lives with new opportunities for self-expression, socialisation, and empowerment.

  • The Use of Online Communities of Practice in the Software Industry: Learnings from Facebook Communities in Sri Lanka   Order a copy of this article
    by Manoja Weerasekara, Åsa Smedberg 
    Abstract: Online communities of practice (CoPs) for professionals is a growing phenomenon in social networking. Such an online CoP consists of people who share their work-related knowledge, experiences, ideas, and practices using different electronic modes. The study focuses on the potential use of online CoPs for social support among software professionals who need to manage a demanding work-life. Five Facebook (FB) groups comprising software employees were cross-examined qualitatively using thematic analysis. The results revealed how software engineers engaged in different practices and activities to support each other in the communities. It was noted how the group members exerted social support, which is considered a key element in occupational health. The findings provide promising insights into how software professionals collaborate and support each other in cyberspace, which could be further explored to design technology that could foster online communities for software employees who need to manage their occupational stress.
