This paper aims to investigate the multihoming behavior of users on social networking web sites in the absence or the presence of product differentiation.

The approach is to build a theoretical model to explain the multihoming behavior of users on social networking web sites.

Under multihoming without product differentiation, all members of the smaller network multihome to the bigger network and the social networking web site with the bigger network size benefits from multihoming. Under multihoming with product differentiation, when the smaller network differentiates its product from the bigger network, then all members of the bigger network will multihome to the smaller network. Welfare is higher for both sided multihoming and both sided multihoming will happen only when the social networking web sites are differentiated in terms of features.

The model is a theoretical model and will need to be tested empirically.

The results of the model indicate that multihoming results in increased utility for the users of social networking web sites when the two web sites are differentiated in terms of features.

From the literature available in the public domain, the paper has not found any existing theoretical model to explain multihoming behavior of users on social networking web sites. The paper fulfils this objective.

Rooted in adult fear, adult authority aims to protect and control youth (Gannon, 2008; Valentine, 1997). Continuously negotiating for freedom, youth search for adult-free public spaces and are therefore extremely attracted to social networking sites (boyd, 2007, 2014). However, a significant portion of youth now includes adult authorities within their Facebook networks (Madden et al., 2013). Thus, this study explores how youth navigate familial- and educational-adult authorities across social networking sites in relation to their local peer culture.

Through semi-structured interviews, including youth-centered and participant-driven social media tours, 82 youth from the Northeast region of the United States of America (9–17 years of age; 43 females and 39 males) shared their lived experiences and perspectives about social media during the summer of 2013.

In their everyday lives, youth are subjected to the normative expectations emerging from peer culture, school, and family life. Within these different and at times conflicting normative schemas, youth’s social media use is subject to adult authority. In response, youth develop intricate ways to navigate adult authority across social networking sites.

Adult fear is powerful, but fragile to youth’s interpretation; networked publics are now regulated and youth’s ability to navigate then is based on their social location; and youth’s social media use must be contextualized to be holistically understood.

Social media experience a rapid rise in recent years and steep into almost every aspect of people's lives by altering their lifestyles and creating an impact on their wellbeing. The purpose of the present study is to examine the influence of SNSs on life satisfaction among university students by first exploring what are the key gratifications which motivates them to engage in SNSs and then focusing on the psychological outcomes including social overload and social benefit from using SNSs that affects life satisfaction among the university students.

Theory of social influence and uses and gratifications theory were used in this study to examine the motivations for using SNSs, and the impact of psychological outcomes associated with SNSs usage, i.e. social benefit and social overload on life satisfaction among university students of Pakistan. Partial least squares-structural equation modeling is used to analyze the data.

The outcomes indicate that the need for maintaining interpersonal interconnectivity, entertainment value and social enhancement value derives the students' participation in social networking sites through which they encounter social benefit and social overload. The presence of social benefit enhances life satisfaction while social overload results in decreasing life satisfaction of students. Using social networking sites influences life satisfaction in the presence of social overload and social benefit while there is no direct influence of social networking sites on life satisfaction was evidenced.

The present study investigated the needs that drive the use of social media through the lens of UGT & Social influence approach. The other potential determinants of social media usage intention should be analyzed by employing variables of the other models.In this study social media was examined as a general platform used by the university students of Pakistan. In future researches the driving needs should be examined in the context of specific social networking sites.

The presented findings embraces the implications for the authorities of higher education institutions and policy makers as it provides the useful insights about student 2019s motivations and participation behavior in SNSs which would help in developing strategies for desirable results.

Educational institutions can utilize the research findings by incorporating social media tools in the academic system, student's interaction with their mentors will lead towards enhanced involvement of students and intellectual skills along with upgraded academic performance which will positively influence life satisfaction of the students.

The scarcity of findings was observed in the local environment specifically in the context of SNSs usage and well-being of the higher education students. This study addresses the motivational factors of SNSs usage and their psychological outcomes simultaneously and focused on the investigation of social media usage drivers and its outcomes among the university students of Pakistan.

The goal of this paper is to examine the use of the major social networking tools in academic libraries in the USA. As college students are heavy users of social networking, such efforts provide academic libraries with outreach possibilities to students who do not use the physical library. The paper also seeks to examine the concerns about their use both from students and within the academic library.

The paper summarizes findings from articles published since 2006 found in the Library Literature and Information Full Text database. The first author also examined librarian blogs and library accounts in various social networking sites.

Social networking can be an effective method of student outreach in academic libraries if libraries take care to respect student privacy and to provide equal coverage for all subject areas.

Most information about social networking is anecdotal with very little statistical analysis of its effectiveness. The popularity of the various social networking sites can change quickly.

Academic libraries should consider using social networking as an outreach effort but take care to avoid the potential negative consequences.

This paper provides a snapshot on the use of social networking in academic libraries through a thorough review of the available literature and an examination of the libraries' presence on the most popular social networking sites. It also provides help for academic libraries wishing to implement social networking.

The purpose of this paper is to investigate users' knowledge and use of social networking sites and folksonomies to discover if social tagging and folksonomies, within the area of independent music, aid in its information retrieval and discovery. The sites examined in this project are MySpace, Lastfm, Pandora and Allmusic. In addition, the ways in which independent record labels utilise social networking sites for promotion are investigated.

Three groups of participants were surveyed using questionnaires. These groups were music concert attendees, people who responded to online postings to social networking sites, and independent record companies. In addition interviews were held with digital music experts.

The results suggest that respondents use social networking sites for music discovery but are not generally aware of folksonomic approaches to music discovery. When users do use and contribute to the folksonomy, most respondents were found to tag for personal retrieval purposes rather than attempting to aid the retrieval purposes of the population of site users as a whole. The four record labels unanimously agreed that social networking sites are having a major impact on independent music discovery. Digital distribution has a major impact on independent record labels. It facilitates discovery but at the same time digital distribution creates new promotional dilemmas.

The project is small scale but the research area is a relatively novel one, and the results are interesting enough to share more generally in the hope that this project will stimulate further research activity in this area.

The purpose of this paper is to identify the practices that owners of public profiles in social networking sites can leverage to actively build online reputation and to evaluate the impact of the adoption of such practices on the initial formation of trust toward these individuals when they are presented as new virtual work partners.

A theoretical model was developed and an experiment with 233 participants was utilized to assess the model using partial least squares structural equation modeling.

The results suggest that individuals can build their online reputations in public profiles of social networking sites via a series of practices of self-disclosure of information and that the adoption of these practices has significant effects on the initial formation of trust toward the profile owner in virtual work contexts. Categorization mechanisms such as stereotyping, unit grouping and reputation categorization have been found to contribute to the initial formation of trust, both from an affect and cognition-based perspectives.

Little is known about the information disclosure practices in public profiles of social networking sites that new work partners can adopt to facilitate the formation of trust between them before they start working together. This study has contributed to the existing body of literature by clarifying these practices and the relative importance of online reputation to the initial formation of trust during the outset of a new virtual work relationship.

This viewpoint essay seeks to argue that young people's online social networking can serve as sites for and supports for student learning in ways not currently assessed.

The two themes presented are based on a select review of the research literature as well as the author's explorations of young people's online social networking practices within MySpace and Facebook, two naturally occurring, youth‐initiated sites, as well as in an online social networking application designed for environmental science education and civic action.

Two themes are presented: (1) social network sites can serve as direct and indirect supports for learning, such as providing an emotional outlet for school‐related stress, validation of creative work, peer‐alumni support for school‐life transitions, and help with school‐related tasks; and (2) online social networking can stimulate social and civic benefits, online and offline, which has implications for education.

Currently, social media are largely blocked in schools due to privacy, security, and copyright concerns. In the USA, the National Educational Technology Plan published in November 2010, and recent educational standards, both assume 24/7 access and use of newer web technologies for learning and advocate appropriation of technologies students already use, and prefer to use, for educational purposes. Consideration of how social media, such as social network sites, currently support informal learning may advance one's ability to construct effective social media‐enabled environments for more formal learning purposes.

This paper presents concrete examples of how social network sites, typically seen as a distraction, might be re‐envisioned as supports for revised student learning outcomes.

Digital cameras and social networking have made photo-taking and photo-sharing more ubiquitous than ever before. In recent years, scholars and the popular press have raised concerns over the practice of posting photographs on social networking sites, especially when the images contain problematic or incriminating content. These concerns are often directed toward college students, who are among the most active users of social media. To that end, this chapter offers a comprehensive overview of the extent and emerging research pertaining to college students' photo-sharing habits on social networking sites. Much of our attention focuses on Facebook, which has emerged as the largest and fastest growing photo-sharing Web site in the world. While research on text-based disclosure will be addressed, a greater emphasis is placed on college students' photo-related behaviors, including uploading, viewing, tagging, and untagging photos. Further, this chapter discusses research on problematic or damaging content in college students' photos posted on Facebook, including depictions of alcohol use, drug use, and sexual promiscuity. This chapter provides a glimpse of some recent data (collected by the author) from a national sample of U.S. college students, which further shed light on their experiences and attitudes regarding their photo-related Facebook behaviors, the types of incriminating photos they report posting, and the consequences they have experienced due to visual images shared by themselves or others on Facebook. Finally, this chapter concludes with a discussion of the strategies utilized by college administrators, faculty, athletic coaches, and others within higher education to address the concerns and consequences often associated with college students and the photographs they share on Facebook and other social networking sites.

Given the widespread popularity of social media, such as Twitter, Facebook, Google+, and LinkedIn, theorizing and understanding the user attitude and usage behavior of social media site is fundamental in developing future understandings and deployment of these new technologies. One approach to such studies on drivers of social media usage behavior would be to revisit the technology acceptance model (TAM). The purpose of this paper is to discuss these issues.

Decades of extensive research have focussed on validating the TAM, proposed by Davis (1986), for various types of information systems and communication technologies. TAM forecasts individual adoption and voluntary use of technology. This study examines individual adoption behavior of the most popular social networking site Facebook. The influences on the intention of using social networking based on individual's perceived ease of use (EU), the user's critical mass (CM), social networking site capability (CP), perceived playfulness (PP), trustworthiness (TW), and perceived usefulness (PU) is empirically examined with a primary data set of 398 users of Facebook gathered from a web-based questionnaire survey.

The results demonstrate that the revised social media TAM model proposed in this study supports all the hypotheses of social media usage behavior. The results of this study provide evidence for the importance of additional key variables to TAM in considering user engagement on social media sites and other social-media-related business strategies.

Based on our review of existing scientific literature on social media, few empirical studies have been conducted to scientifically evaluate and explain the usage behavior of social media using Facebook. A validated instrument of usage behavior of social media can provide usability experts and practitioners with a validated tool to assess social media acceptance and usage behavior. This can help us gain a better understanding of “who is and who is not using these sites, why and for what purposes” (Boyd and Ellison, 2007).

The purpose of the studies was to test if extent of prior social media activity could predict likelihood that a consumer would post reviews on a new review website.

Two online surveys were conducted presenting scenarios in which users were asked about prior social media activity, the number of social networks they belonged to in study one, and how actively they had posted reviews in study two. These questions were followed by descriptions of new review websites, a general local merchant review website in study one and a local restaurant review website in study two.

Although demographics did a poor job of predicting who would post reviews on the new review websites, prior active social media use and review posting did modestly predict intention to post reviews on the new review websites.

This is not an experimental study and so causality cannot be claimed. Descriptively, although the results were consistent in two studies using different stimuli, other factors might prove to be better predictors of active user‐generated content for other types of sites.

The findings suggest a simple and effective way for two‐sided platform managers to identify potential active reviewers so that they can target them through marketing strategies to encourage their essential participation and less‐active users can be similarly targeted to encourage modest use.

No other studies can be found that focus on this aspect of managing two‐sided platforms. The results might be important for managers of other similar websites that depend on user‐generated content for their value.
