An Empirical Study Evaluating Social Networking Continuance and Success

Social networking site (SNS) use decisions have led to major economic and social transformations worldwide. While many organizations seek to use SNSs from a strategic perspective to reach their customer, it is important to understand what makes SNSs successful in order to use them for competitive purposes. The current research evaluates the influence of the social capital theory on SNS success measures. A model was developed and empirically tested using two data samples to ensure valid and reliable results for success of SNSs. The results display the importance of social capital in SNS success followed by practitioner and academic implications.     

Correlation between Facebook use for educational purposes and academic performance of students

In this paper a research on the application of Facebook in education is presented. A total of 139 students of the Faculty of Education in Sombor (Serbia) participated in the research. The results establish a positive correlation between the academic performance of students and the frequency of use of Facebook for educational purposes. The factor of perceived usefulness greatly affected the decision of students to use Facebook as a learning aid. No significant difference in the frequency of use of Facebook for general purposes has been reported between the groups of students divided by the academic performance.     

College students’ disclosure of location-related information on Facebook

This study drew on existing research and three behavioral intention models to develop the beginning of a new model to explain why college students share their locations on Facebook. Findings showed that students were more likely to disclose their location on Facebook if their friends did so, a concept called subjective norm. Results also showed that subjective norm had an indirect effect on whether people disclosed their location, mediated through people’s attitude toward disclosure, while controlling for usefulness of disclosing. Collectively, this model explained 61% of the variance in why college students share locations on Facebook. Findings are discussed in relation to behavioral-intention models, and practical implications for social media companies are offered.

The dark side of social networking sites:Understanding phishing risks

LinkedIn, with over 1.5 million Groups, has become a popular place for business employees to create private groups to exchange information and communicate. Recent research on social networking sites (SNSs) has widely explored the phenomenon and its positive effects on firms. However, social networking's negative effects on information security were not adequately addressed. Supported by the credibility, persuasion and motivation theories, we conducted 1) a field experiment, demonstrating how sensitive organizational data can be exploited, followed by 2) a qualitative study of employees engaged in SNSs activities; and 3) interviews with Chief Information Security Officers (CISOs). Our research has resulted in four main findings: 1) employees are easily deceived and susceptible to victimization on SNSs where contextual elements provide psychological triggers to attackers; 2) organizations lack mechanisms to control SNS online security threats, 3) companies need to strengthen their information security policies related to SNSs, where stronger employee identification and authentication is needed, and 4) SNSs have become important security holes where, with the use of social engineering techniques, malicious attacks are easily facilitated.     

Emotional disclosure on social networking sites: The role of network structure and psychological needs

We conducted three studies to understand how online emotional disclosure is influenced by social network structure on Facebook. Results showed that emotional disclosure was associated with both the density and size of users’ personal networks. Facebook users with denser networks disclosed more positive and negative emotions, and the relation between network density and emotional disclosure was mediated by stronger need for emotional expression. Facebook users with larger networks on Facebook disclosed more positive emotions, and the relation between network size and emotional disclosure was mediated by a stronger need for impression management. Our study extends past research by revealing the psychological mechanisms through which personal social network structure influences emotional disclosure. It suggests that social network size and density are associated with different psychological needs, which in turn lead to different patterns of emotional disclosure.     

Gravitating towards Facebook (GoToFB): What it is? and How can it be measured?

In its current state, the Facebook literature speaks very little about metrics developed specifically for this important social networking service. This study tries to fill part of this gap by conceptualizing, developing and validating a new Facebook use construct, “Gravitating towards Facebook” (GoToFB). Unlike traditional Facebook usage views that have focused on lean usage measures, the one presented in the current study offers a broader conceptualization of the same by taking into account the interaction among three elements: the user, Facebook features, and task. This investigation has put extensive efforts to validate the new Facebook instrument using a series of exploratory and confirmatory scale development techniques and found that it exhibits adequate measurement properties. The resultant scale consists of eight dimensions: connecting, sharing, relaxing, organizing, branding, monitoring, expressing, and learning. The instrument would be useful for businesses looking for deeply understanding how potential customers use Facebook and for researchers seeking to develop and test Facebook success models.     

“Why are they commenting on his page?”: Using Facebook profile pages to continue connections with the deceased

This study examines what the living discuss on the Facebook profile pages of deceased loved ones and how these messages change over time. A content analysis of 2533 messages posted on ten deceased individuals’ Facebook profile pages reveals that messages to the deceased reflect three themes: Processing the Death, Remembering the Deceased, and Continuing the Connection. An analysis of messages over time indicates that posts pertaining to processing the death and remembering the deceased peak immediately after loss and then decrease in frequency, while messages signaling continued connections increase with time. In discussing the results, this study seeks to expand upon Continuing Bonds theory and existing literature on grief communication online.     

Twitter versus Facebook: Exploring the role of narcissism in the motives and usage of different social media platforms

The amount of research on social networking sites (SNS) and narcissism is accumulating quickly requiring greater levels of variable specification and more fine-tuned hypothesis testing to clearly determine the relationships among key variables. The current investigation examines two of the most popular SNS, Facebook and Twitter, formulating hypotheses around the specific features of each site within college and adult samples. Unlike previous research that has focused almost exclusively on SNS usage, we focused on active usage (i.e., SNS content generation) as opposed to passive usage (i.e., SNS consumption) and included reasons for usage as a potential black box in the narcissism to SNS usage relationship. Results suggest that the features of Twitter make tweeting the preferred means of active usage among narcissists in the college sample, but not the adult sample, who prefer Facebook. In fact, we found no significant direct or indirect relationship with active usage on Facebook for the college sample, calling into question popular press articles linking Millennial narcissism with Facebook use. Additionally platform differences (i.e., microblogging versus profile-based) may explain the importance of active usage on Twitter relative to Facebook. That is, with Twitter, narcissistic motives for usage all manifest through tweeting while Facebook provides other mechanisms to achieve narcissistic motives.     

College student cyberbullying on social networking sites: Conceptualization,prevalence, and perceived bystander responsibility

The majority of research on cyberbullying has been conducted with middle school and high school students and has not focused on specific technology platforms. The current study investigated college student experiences with cyberbullying on Social Networking Sites (SNS). College students (N = 196) from a northwestern university shared their conceptualizations of what cyberbullying looked like on SNS. Some college students (19%) reported that they had been bullied on SNS and 46% indicating that they had witnessed cyberbullying on SNS. The majority (61%) of college students who witnessed cyberbullying on SNS did nothing to intervene. College students were also asked about their perceived responsibility when they witnessed cyberbullying on SNS. Two diverging themes emerged that indicated some college students believed their responsibility to intervene was circumstantial, while others believed there is a constant clear level of responsibility for college student cyberbullying bystanders on SNS.
