Detecting and tagging users’ social circles in social media

As a media and communication platform, microblog becomes more popular around the world. Most users follow a large number of celebrities and public medias on microblog; however, these celebrities do not necessarily follow all their fans. Such one-way relationship abounds in ego network and is displayed by the forms of users’ followees and followers, which make it difficult to identify users’ real friends who are contained in merged lists of followees and followers. The aim of this paper is to propose a general algorithm for detecting users’ real friends in social media and dividing them into different social circles automatically according to the closeness of their relationships. Then we analyze these social circles and detect social attributes of these social circles. To verify the effectiveness of the proposed algorithm, we build a microblog application which displays algorithm results of social circles for users and enables users to adjust proposed results according to her/his real social circles. We demonstrate that our algorithm is superior to the traditional clustering method in terms of F value and mean average precision. Furthermore, our method of tagging social attributes of social circles gets high performance by NDCG (normalized discounted cumulative gain).     

Permanently online – Permanently connected: Explorations into university students’ use of social media and mobile smart devices

BackgroundWith the availability of mobile smart devices, many adolescents have developed the habit of being online and connected with other users almost all the time.ObjectiveThe aim of this paper is to provide a definition of being permanently online (PO) and permanently connected (PC) and to explore students’ current PO/PC behaviors.MethodsAn online survey was conducted with 178 university students in Germany to explore the intensity of their PO/PC behaviors in various social situations, the differences in being PO and being PC, students’ feelings about a possible loss of Internet access, and their online responding behaviors. We also shed some light on the associations between being PO/PC and various aspects of well-being, as well as between PO/PC and demographics and lifestyle.ResultsSmart device usage behaviors at night and behaviors in various social situations during the day indicate that PO and PC behaviors are occurring frequently. The results show that being connected to others (PC) seems to be more relevant to the participants than browsing the web (PO). Moreover, the participants expressed strong emotional responses about a temporary loss of Internet access. Coping behaviors in response to increasing number of incoming messages and permanent availability are reported.ConclusionThis exploratory study demonstrates the relevance of the concepts of being PO and PC to students, and points out further research gaps.     

Employees’ proactiveness on enterprise social media and social consequences: An integrated perspective of social network and social exchange theories

This study delves into how employee proactiveness on enterprise social media can influence social outcomes at work, both positively and negatively. Drawing on social network and social exchange theories, we develop a model to understand how virtual proactiveness is perceived by leaders and coworkers. Using a round-robin design, we collected data from 281 respondents in 56 teams across three waves. The results show that affiliative and challenging proactiveness positively relate to leader-member and team-member exchanges. However, challenging proactiveness negatively affects team-member exchange, potentially leading to coworker envy. These findings shed light on the intricate social dynamics in remote working environments.     

Introducing social media for knowledge management: Determinants of employees’ intentions to adopt new tools

Although an increasing number of organizations implement social media as means to enhance internal knowledge exchange, employees are in many cases not motivated to make use of new technologies. Therefore, the purpose of this study is to identify antecedents of employees’ intentions to adopt social media for knowledge exchange. Measured factors were derived from expectancy theory and technology acceptance model. To identify factors influencing the willingness to seek and contribute knowledge using social media, in this study N = 315 employees within one organization were surveyed. The results clearly support the predictions: the interplay between the importance and deficits concerning knowledge exchange, perceived usefulness of social media for knowledge exchange, and experience in social media use jointly affected the intention to apply social media for knowledge exchange after their implementation.     

The interplay between users’ intraorganizational social media use and social capital

The wide acceptance of social media by the public has caused companies try to use intraorganizational social media to increase employee work performance. However, simply implementing a platform is insufficient for success. Companies must encourage employees to use social media for work-related purposes. This study divided the use of intraorganizational social media into social- and work-related use and proposed a model based on the theory of social capital to explore the effects of social-related use on work-related use. The model was tested using a survey of users of intraorganizational microblog systems in China. The results indicate the relationships among two types of intraorganizational use and the dimensions of social capital, and that social-related use fosters work-related use directly and indirectly by enhancing social capital. These results facilitate an understanding of the value of social activities conducted using intraorganizational social media in organizations.     

Predictors of job seekers’ self-disclosure on social media

Social media-based screening is a well-known practice to both recruiters and job seekers. Little is known, however, about how job seekers present themselves on social media, i.e. ‘self-disclosure’, for employment purposes. This study builds on the theories of hyperpersonal computer-mediated communication, self-efficacy and social exchange to examine job seekers’ professional online image concerns, social media self-efficacy, and perceptions of social media effectiveness in the job search as predictors of inappropriate and career-oriented self-disclosures on these media. Findings from a sample of 3374 Italian respondents showed that career-oriented self-disclosure was predicted by all three factors, whereas inappropriate self-disclosure was only predicted by social media self-efficacy. Furthermore, the relationship between professional online image concerns and inappropriate self-disclosure was moderated by age, education and work experience, but not by gender. Theoretical and practical implications are discussed, and directions for future research are suggested.     

Using social media to enrich information systems field trip experiences: Students’ satisfaction and continuance intentions

A well-designed field trip can promote active learning and reinforce classroom materials. Few studies have examined the potential for social media to enhance IS field trip experiences by promoting active and collaborative learning. One major barrier to the exploitation of this potential is the lack of the adoption of social media by students as a learning tool to enhance field trip experiences. Therefore, the first task is to understand how to increase the satisfaction of students in their use of social media to enhance IS field trips. This research sets out to understand the factors that could help increase students’ satisfaction with the use of social media to enhance IS field trips, and thereby their intentions to continue to use social media in future field trips. The results show that to increase user satisfaction, course instructors should ensure that students perceive the social media sites used for enhancing field trip study to be trustworthy, effortless, useful and accepted by their peers. Future research could determine how we can incorporate the use of social media to enhance the field trip learning experience.

Are heavy users of computer games and social media more computer literate?

Adolescents spend a substantial part of their leisure time with playing games and using social media such as Facebook. The present paper examines the link between adolescents' computer and Internet activities and computer literacy (defined as the ability to work with a computer efficiently). A cross-sectional study with N = 200 adolescents, aged 17 on average, was conducted. Hierarchical regression analyses showed that an increase in time spent playing games on a PC/Mac was related to higher scores on practical and theoretical computer knowledge. Moreover, practical computer knowledge was higher for adolescents who liked playing shooters, fantasy games, or Facebook-games. Frequency of social media use was associated with higher scores in practical computer knowledge. A bootstrap analysis indicated that this relationship was mediated by a decrease in computer anxiety, not by more positive attitudes toward the computer. Gender yielded substantial main effects on the media literacy variables but the associations between the computer and Internet activities and the literacy aspects were similar for boys and girls. This study is expected to encourage future longitudinal research on adolescents' incidental learning during leisure time computer and Internet activities.

Is the social use of media for seeking connectedness or for avoiding social isolation? Mechanisms underlying media use and subjective well-being

This study provides a resolution for two contrasting hypotheses around media use, the augmentation and the displacement hypotheses. To do this, we conducted an online survey of 300 Korean adults examining the relationships among the social use of media, face-to-face communication, social isolation, connectedness, and subjective well-being. The results indicate that connectedness, not avoiding social isolation, mediates the effects of the social use of media on subjective well-being. On the other hand, both connectedness and avoiding social isolation mediate the effects of face-to-face communication on subjective well-being. These results suggest that the social use of media is limited to seeking connectedness to others, whereas face-to-face communication can facilitate avoiding social isolation as well as seeking connectedness, which can explain why the two contrasting hypothesis, the augmentation and the displacement hypotheses, can be right. In the domain of seeking connectedness, media can augment face-to-face communication. On the other hand, in the domain of avoiding social isolation, media may displace face-to-face communication.     

How social media influence college students’ smoking attitudes and intentions

Building on the influence of presumed influence (IPI) model, this study examines how smoking-related messages on social media influence college students’ smoking. We surveyed 366 college students from three U.S. Midwestern universities in 2012 and examined the effects of expression and reception of smoking-related messages on smoking using path analysis. We found that the expression and reception of prosmoking messages not only directly affected smoking but also had indirect effects on smoking through (1) perceived peer expression of prosmoking messages and (2) perceived peer smoking norms. For antismoking messages, only reception had a significant indirect influence on smoking through (1) perceived peer reception of antismoking messages and (2) perceived peer smoking norms. In conclusion, social media function as an effective communication channel for generating, sharing, receiving, and commenting on smoking-related content and are thus influential on college students’ smoking.     

Integrated microblog sentiment analysis from users’ social interaction patterns and textual opinions

Traditional post-level opinion classification methods usually fail to capture a person’s overall sentiment orientation toward a topic from his/her microblog posts published for a variety of themes related to that topic. One reason for this is that the sentiments connoted in the textual expressions of microblog posts are often obscure. Moreover, a person’s opinions are often influenced by his/her social network. This study therefore proposes a new method based on integrated information of microblog users’ social interactions and textual opinions to infer the sentiment orientation of a user or the whole group regarding a hot topic. A Social Opinion Graph (SOG) is first constructed as the data model for sentiment analysis of a group of microblog users who share opinions on a topic. This represents their social interactions and opinions. The training phase then uses the SOGs of training sets to construct Sentiment Guiding Matrix (SGM), representing the knowledge about the correlation between users’ sentiments, Textual Sentiment Classifier (TSC), and emotion homophily coefficients of the influence of various types of social interaction on users’ mutual sentiments. All of these support a high-performance social sentiment analysis procedure based on the relaxation labeling scheme. The experimental results show that the proposed method has better sentiment classification accuracy than the textual classification and other integrated classification methods. In addition, IMSA can reduce pre-annotation overheads and the influence from sampling deviation.     

‘You talking to me?’ The influence of peer communication on adolescents’ persuasion knowledge and attitude towards social advertisements

This article examines how peer communication among adolescents (14–16 years) affects the evaluation of social advertising (i.e. targeted ad that adopts the social proof heuristic by using an individual’s social ties as endorsers for a brand) on social networking sites (SNSs). More precisely, the focus lies on how engaging in online peer chatting on these social platforms alters persuasion knowledge and attitude towards the ad. In order to test this, two between-subjects experiments were conducted in which adolescents chatted with peers on a mock SNS that contained a social ad. In Experiment 1, results reveal that a social ad generates a more positive attitude among adolescents when they have engaged in online peer communication, and at the same time, triggers less persuasion knowledge. In Experiment 2, the depth of the relationship between the chatters (tie strength) plays a significant moderating role as peer communication with strong ties yields greater effects, compared to communication with weak ties. These findings reveal important social influence dynamics that may alter the elaboration of persuasive communication, leading to valuable theoretical and practical implications.     

Enterprise social media and cyber-slacking: A Kahn’s model perspective

This study investigates the associations between enterprise social media (ESM) use, psychological conditions, and cyber-slacking in the workplace and examines the mediating role of psychological conditions between ESM use and cyber-slacking. The study utilizes Kahn’s framework to develop a research model and investigate various associations, and it employs a cross-sectional design, testing the developed research model with 277 ESM users from Chinese enterprises. The study results suggest that ESM use stimulates various psychological conditions that discourage cyber-slacking behaviors and significantly mediate the associations between ESM use and cyber-slacking.     

What motivates health information exchange in social media? The roles of the social cognitive theory and perceived interactivity

Social media has become an attractive platform for users to exchange health information with others. However, little research has been done to identify the determinants of health information exchange. By integrating aspects of the social cognitive theory and perceived interactivity, this study proposes a research model to investigate the antecedents of health information exchange in social media. Data collected from Facebook users with health information exchange experience were used to examine the proposed model. The results demonstrate that human-to-human interaction, human-to-information interaction, outcome expectation of health self-management competence, and outcome expectation of social relationships have a significant impact on health information exchange behavior. The results also reveal that human-to-human interaction exerts a significant influence on the outcome expectation of health self-management competence and the outcome expectation of social relationships, while human-to-information interaction has a positive effect on the outcome expectation of health self-management competence. The implications for the theory and practice and future research directions are discussed.     

Subjective well-being and social media use: Do personality traits moderate the impact of social comparison on Facebook?

The purpose of the study was to explore whether personality traits moderate the association between social comparison on Facebook and subjective well-being, measured as both life satisfaction and eudaimonic well-being. Data were collected via an online questionnaire which measured Facebook use, social comparison behavior and personality traits for 337 respondents. The results showed positive associations between Facebook intensity and both measures of subjective well-being, and negative associations between Facebook social comparison and both measures of subjective well-being. Personality traits were assessed by the Reinforcement Sensitivity Theory personality questionnaire, which revealed that Reward Interest was positively associated with eudaimonic well-being, and Goal-Drive Persistence was positively associated with both measures of subjective well-being. Impulsivity was negatively associated with eudaimonic well-being and the Behavioral Inhibition System was negatively associated with both measures of subjective well-being. Interactions between personality traits and social comparison on Facebook indicated that for respondents with high Goal-Drive Persistence, Facebook social comparison had a positive association with eudaimonic well-being, thus confirming that some personality traits moderate the association between Facebook social comparison and subjective well-being. The results of this study highlight how individual differences in personality may impact how social comparison on Facebook affects individuals’ subjective well-being.     

Reading others’ comments and public opinion poll results on social media: Social judgment and spiral of empowerment

Applying Social Judgment Theory and the Spiral of Silence, we tested the effects of online comments and public opinion polls on the public's’ latitude of acceptance of others' online comments, attitude toward a company, and willingness to speak out on Social Media. We conducted two experiments and found that the effects of online comments and public opinion polls interact with individuals' prior attitudes toward a corporation. The latitude of acceptance toward online comments and participants' willingness to speak out online increased as the comments themselves became negative only among people with negative prior attitudes. However, the change was not detected among people with positive prior attitudes. Practical and theoretical implications were further discussed.
