Modeling job effectiveness and its antecedents from a social capital perspective: A survey of virtual teams within business organizations

This study develops two alternative models concerning job effectiveness, knowledge sharing, and their antecedents related to individuals’ perception about their job effectiveness in a team. Model 1 of this study intends to be as parsimonious as theoretically justifiable. It posits that three dimensions of social capital - structural, relational, and cognitive social capital - simultaneously influence knowledge sharing and job effectiveness indirectly through the mediation of team commitment, while job effectiveness is also influenced by knowledge sharing. Based on Model 1, Model 2 further adds that knowledge sharing is influenced directly by three dimensions of social capital. The two models are tested by collecting data from professionals of virtual teams in high-tech industries. The test results support seven out of nine hypotheses in Model 2. Finally, managerial implications of the empirical findings are also discussed.     

Dimensionality of Social Capital and Organizational Citizenship Behavior in Information Systems Project Teams

Knowledge sharing and organizational citizenship behavior (OCB) among project team members are crucial for project success due to the particularities of information systems (IS) projects. Bonding social capital is known to increase knowledge sharing and collaboration. However, the influence of bridging social capital on knowledge sharing is unclear. The interplay between bridging and bonding social capital is especially interesting in a collectivistic society such as South Korea where in-group ties are particularly strong. In this study, we examine the effect of the sub-dimensions of the above constructs (i.e., bonding, bridging, OCB) on knowledge sharing. The results suggest that bonding and citizenry behavior improves knowledge sharing. Bridging improves knowledge sharing by increasing organizational citizenry behavior. Unexpectedly, the effect of citizenship behavior on knowledge sharing differs from the effect of its sub-dimensions. Only helping others is positively related to knowledge sharing. Similarly, the sub-dimensions of bridging and bonding influence knowledge sharing and citizenship behavior differently than the first-order constructs. For example, shared team mental model positively affects OCB, but has no direct influence on knowledge sharing. Conversely, shared vision is the only sub-dimension of bridging that positively affects OCB. Thus, the results suggest that project managers should facilitate shared project vision and team mental model to encourage team members’ citizenship behavior and control the potential adverse influence of bridging social capital.     

Knowledge sharing in information system development teams: examining the impact of shared mental model from a social capital theory perspective

Shared mental model (SMM), a concept from psychology, is defined as a common thinking style developed when individuals perform similar tasks in a cohesive manner. In this article, we investigate the relationship between the three dimensions of social capital and SMM. We also examine whether SMM mediates the impact of social capital on knowledge sharing (KS) behaviour in information system development (ISD) teams. Social capital is defined as the resource of social relationships owned by individuals. It is useful for explaining human behaviour in social networks. The data collected represent 492 ISD professionals in 118 teams from 18 middle-sized enterprises. The results of this study indicate that social capital theory is useful for explaining the antecedents of SMM, and SMM is positively related to KS and team performance. This research also emphasises the importance of developing SMM in a team.     

Investigating the influence of age,social capital affinity,and flow on positive outcomes reported by e-commerce site users

This study investigated the role of social capital affinity (the sense of community and likeness felt for people online) and the experience of flow (concentrated engagement in/enjoyment of an activity) as antecedents to a variety of positive outcomes associated with the use of e-commerce sites. Also, based on socio-emotional selectivity theory, the current study assessed the influence of age on social capital affinity and flow. As a subset of data from a telephone sample of Internet users in the USA, 282 e-commerce users responded to questions about site satisfaction, perceived focused and incidental knowledge-gains, and affirmation, in addition to flow and social capital affinity. As predicted by socio-emotional selectivity theory, there was a negative relationship between age and social capital affinity and flow. Flow, for its part, mediated the effects of age and social capital affinity on perceived focused and incidental knowledge-gain, satisfaction and affirmation among participants reporting e-commerce use. Finally, the current results indicated that satisfaction and perceived incidental learning predicted participant affirmation for their chosen e-commerce site.     

Reality Television as a Model for Online Behavior: Blogging, Photo, and Video Sharing

This research explores traditional mass media as an antecedent to nondirected self-disclosure online. New Internet-based tools allow users to communicate with global audiences, and to make intimate personal information available to this audience. At the same time, a culture that rewards the public performance of private thoughts and emotions is increasingly evident in "reality" television (RTV) programming. This study used survey data to examine RTV consumption, authoritarianism, and users' offline social context as potential antecedents for nondirected self-disclosure via blogs, online photo sharing, and online video sharing. RTV consumption correlated with blogging and video sharing, but not photo sharing. Social support network size was a significant correlate of photo sharing, indicating that photo sharing may be a more relational activity.     

The reciprocal effects of social network site use and the disposition for self-disclosure: A longitudinal study

Since the advent of social network sites (SNSs), scholars have critically discussed the psychological and societal implication of online self-disclosure. Does Facebook change our willingness to disclose personal information? The present study proposes that the use of SNSs and the psychological disposition for self-disclosure interact reciprocally: Individuals with a stronger disposition show a higher tendency to use SNSs (selection effect). At the same time, frequent SNS use increases the wish to self-disclose online, because self-disclosing behaviors are reinforced through social capital within the SNS environment (socialization effect). In a longitudinal panel study, 488 users of SNSs were surveyed twice in a 6 months interval. Data were analyzed using structure equation modeling. The proposed reciprocal effects of SNS activities and self-disclosure were supported by the data: The disposition for online self-disclosure had a positive longitudinal effect on SNS use which in turn positively influenced the disposition for online self-disclosure. Both effects were moderated by the amount of social capital users received as a consequence of their SNS use.     

Trust in product review blogs: the influence of self-disclosure and popularity

Many modern consumers use blogs as important information sources, which they evaluate on the basis of blog-specific cues. Using the theory of self-disclosure, this study posits that bloggers' product evaluation self-disclosures, social self-disclosures, and blog popularity are key determinants of readers' cognitive and affective trust. Readers' trust in turn should affect their product attitudes and feedback intentions towards the blog. With a survey study involving seven blog articles about dining experience and a structural equation model, this research confirms the positive influences of product evaluation self-disclosures and popularity on readers' cognitive trust and of social self-disclosures on readers' affective trust. Both cognitive and affective forms of trust enhance product attitudes. Affective trust also increases readers' feedback intentions towards the blog. With these findings, this study offers suggestions for bloggers and companies that use blogs as marketing tools.     

The role of perceived social capital and flow experience in building users’ continuance intention to social networking sites in China

The long-term development of social networking sites (SNSs) relies on their users’ continuance of use. This paper tested the role of perceived social capital and flow experience in driving users to continue using SNSs based on the expectation–confirmation model of information systems continuance. Using data from online surveys of social networking sites users in China, the proposed model was tested by using the Partial Least Squares (PLSs) technique. The results show that perceived bridging and bonding social capital have different role in building users’ satisfaction and continuance intention: perceived bridging social capital has remarkable influence on users’ satisfaction and continuance intention, but perceived bonding social capital has none. Flow experience has influence on users’ satisfaction but none on continuance intention. In addition, gender has impact on users’ continuance intention.     

Examining interpersonal trust as a facilitator and uncertainty as an inhibitor of intra‐organisational knowledge sharing

This study developed a theoretical model to explore the antecedents of interpersonal trust and the impact of interpersonal trust and uncertainty on intra‐organisational knowledge sharing in highly information‐technology‐mediated work environments. The proposed model was tested empirically using survey data collected from five telecommunication companies. The findings reveal that interpersonal trust has a positive effect on knowledge sharing, while uncertainty has a negative effect upon knowledge sharing. The results also show that social interaction ties and shared knowledge‐sharing vision are the antecedent factors of interpersonal trust, and that uncertainty regarding knowledge sharing is increased by seeker absorptive capability concerns, reciprocity concerns and fear of losing knowledge power. Some important implications for theory and practice as well as directions for future study are discussed.     

The influence of individual,family, and social capital factors on expatriate adjustment and performance: The moderating effect of psychology contract and organizational support

This research is conducted to get more understanding about the antecedents and consequences of expatriate adjustment. Expatriate adjustment is a very important factor for the expatriate and for the organization. As prior studies have explained that family, individual, and social capital factors significantly related to expatriate adjustment, but these studies did not integrate the antecedents and consequences of expatriate adjustment into a more comprehensive research model. Therefore, this study aims to integrate relevant research streams into a more comprehensive model of expatriate adjustment and empirically test the viability of the model. The results of this study illustrated that expatriates with higher emotional intelligence, cultural intelligence, and experience abroad can adjust more easily in the new work environment. Also, family support and family adaptability have positive influence on expatriate adjustment. Expatriates who had prior experiences on parental demand and family to work conflict tend to be able to manage these problems more easily. Furthermore, social capital and mentoring behavior are also important factors that can enhance the success of expatriate adjustment which could further influence expatriate performance, innovative work behavior, knowledge transfer, and organizational performance. Finally, this study also identified that psychological contract and organizational support as two important moderators that can enhance expatriate adjustment and success.     

Consumer adoption of RFID-enabled services. Applying an extended UTAUT model

In this article, an extended version of the unified theory of acceptance and use of technology (UTAUT) is applied to explore the significance of various antecedents of acceptance of eight versions of a radio frequency identification (RFID) enabled service. The results show significant influences from performance expectancy, effort expectancy and technology anxiety on attitude to use RFID-enabled services, while facilitating conditions and attitude to use both have significant influences on intention to use the services. Looking into potential moderating influences, gender moderates most of the relationships in the model while age and experience with identification technology do not seem to be relevant moderators. Exploring the potential moderating influence of context experience, experience of the service context is found to moderate some of the relationships in the model. Managerial implications point to the importance of developing useful and user-friendly services and of communicating the user friendliness to potential customers to avoid the potential negative influence of technology anxiety. Service development and market communication should be sensitive to gender and context experience.     

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.     

Knowledge sharing practices as a facilitating factor for improving organizational performance through human capital: A preliminary test

Organizational knowledge sharing, argued to be able to improve organizational performance and achieve competitive advantage, is often not induced successfully. How organizations should encourage and facilitate knowledge sharing to improve organizational performance is still an important research question. This study proposes and examines a model of organizational knowledge sharing that improves organizational performance. Organizational knowledge sharing practices are argued to be able to encourage and facilitate knowledge sharing, and are hypothesized to have a positive relationship with organizational human capital (employee competencies), which is hypothesized to have a positive relationship with organizational performance. Two organizational antecedents (innovation strategy and top management knowledge values) are hypothesized to lead to the implementation of organizational knowledge sharing practices. The hypotheses were examined with data collected from 256 companies in Taiwan. All the hypotheses are supported. This study has both theoretical and practical implications.     

Understanding the determinants of users’ subjective well-being in social networking sites: an integration of social capital theory and social presence theory

In order to understand the factors affecting users’ well-being perception derived from social networking sites usage, this study integrates the perspectives of social presence theory and social capital theory to develop a research model. Data were collected from 305 users of Facebook in Taiwan to test the model. The findings reveal that structural capital, relational capital, and cognitive capital exert significant influences on subjective well-being. The results also reveal that structural capital and cognitive capital have positive influence on relational capital, while structural capital influences cognitive capital significantly. The results, on the other hand, show that awareness and affective social presence are the antecedents of structural capital, whereas cognitive social presence and affective social presence influence cognitive capital significantly. Finally, affective social presence is associated with relational capital positively. Theoretical and practical implications are discussed.     

Exploring sustained participation in firm-hosted communities in China: the effects of social capital and active degree

Firm-hosted online communities are user-centred, and their efficacy depends on the users’ sustained participation. This study investigated the impact of social capital on users’ continued usage intention. Specifically, since very little work has been done to explore the antecedents of social capital, we tested the role of operator-related and individual-related factors in cultivating social capital by proposing an integrated research model to fill this gap. Furthermore, to gain deeper insights into continuance intention, we postulate that active degree moderates the relationship between social capital and users’ continued usage intention. Our model is empirically examined using survey data collected from 373 members of a well-known firm-hosted online community in China. The results reveal that the firm’s reaction, offline activities, interaction support, seeking reputation and perceived enjoyment are the significant antecedents of social capital. Additionally, social tie and shared vision exert a stronger effect on continued usage intention for active users, whereas identification has a higher influence on continued usage intention for inactive users. Finally, this study discusses the theoretical and practical implications of these findings and provides possible directions for future research.     

Social capital and individual motivations on knowledge sharing: Participant involvement as a moderator

The Internet is a communication channel that allows individuals to share information and knowledge. However, it is not obvious why individuals share knowledge with strangers for no apparent benefit. What are the critical factors influencing such behavior? To attempt to understand this paradox, we combined the theories of social capital and individual motivation to investigate the factors influencing knowledge sharing behavior in a virtual community, applying a participant involvement concept to analyze the moderating effects of individual motivation on knowledge sharing behavior. By analyzing the results of a survey using a questionnaire, we found that altruism, identification, reciprocity, and shared language had a significant and positive effect on knowledge sharing. Reputation, social interaction, and trust had positive effects on the quality, but not the quantity, of shared knowledge. Participant involvement had a moderating effect on the relationship of altruism and the quantity of shared knowledge. Theoretical and managerial implications are discussed.     

Learning and self-disclosure behavior on social networking sites: the case of Facebook users

This paper studies Facebook users’ learning-based attitude formation and the relationship between member attitude and self-disclosure. Through the theoretical lens of learning theories, we recognize the key antecedents to member attitude toward a social networking as stemming from classical conditioning, operant conditioning, and social learning-related factors. In addition, we explore the underlying process through which member attitude affects self-disclosure extent and theorize the mediating role of site usage rate on the relationship between attitude and self-disclosure extent. Analysis of 822 survey data results provides strong support for the role of learning theories in explaining Facebook members’ attitude development. The results also confirm a significant, partial mediating effect of site usage rate. A series of post-hoc analyses on gender difference further reveal that attitude formation mechanisms remain constant between male and female Facebook users; gender difference exists on the association between attitude and self-disclosure extent and the association between site usage rate and self-disclosure extent; and the mediating effect of site usage rate exists in male user group only. Our research, therefore, contributes to the literature on social networking sites, as well as providing behavioral analysis useful to the service providers of these sites.

Knowledge transfer in IT offshoring relationships: the roles of social capital,efficacy and outcome expectations

Information technology (IT) development in global organisations relies heavily on the transfer of tacit and complex knowledge from onshore units to offshore subsidiaries. A central concern of such organisations is the development of social capital, which is known to facilitate the smooth transfer of knowledge. However, only a few studies in IS research have explicitly examined the role of social capital for knowledge transfer in an IT offshoring context. In this paper, we argue that such knowledge transfer mechanisms can be understood better by considering social capital in concert with knowledge senders' efficacy and outcome expectations, two of the potentially key motivational drivers of knowledge transfer. We develop our arguments through a qualitative case study of a large German multinational company. German IT developers in this firm provided in‐depth accounts of their experience with offshore colleagues in an Indian captive subsidiary unit. Drawing on our analysis, we develop a model that depicts the influence of social capital, efficacy and outcome expectations on onshore IT developers' ability and willingness to transfer knowledge to offshore colleagues. Through the model, we also explain how social capital, efficacy and outcome expectations are interrelated and generate three interlocked, self‐reinforcing circles of knowledge transfer success in IT offshoring relationships.     

Knowledge sharing and ERP system usage in post-implementation stage

Many organizations have adopted enterprise resource planning (ERP) systems in recent years to integrate information and information-based processes within and across functional areas. Because of the under-utilization of ERP systems, most of these organizations are disappointed in reaching the anticipated business goals. It is imperative to explore how to facilitate the usage of ERP systems for organizations. This study aims to develop an understanding of the effect of knowledge sharing on ERP system usage and the factors affecting employees’ knowledge sharing after the initial implementation of an ERP system. Selected social oriented theories were employed to develop our conceptual model. By means of a survey of 804 ERP users from 53 Taiwan companies, we confirmed our research model to some extent and found that social capital, intrinsic motivation, and self-efficacy all have significant impacts on knowledge sharing. However, contrary to common belief, we found a negative, though insignificant, effect of extrinsic motivation on knowledge sharing. The implications for research, practice, and future research directions are discussed herein.
