Full and Partial Knowledge Sharing on Intra-Organizational Broadcast Media

Knowledge sharing, along with its potential predictors, has been a popular research topic. This research extends prior research by examining potential predictors of knowledge sharing together within a more comprehensive model with two additional contexts: the type of recipient of the knowledge is the recipients of intraorganizational broadcast media, and the type of knowledge sharing behavior (full knowledge sharing and partial knowledge sharing). The results of this study suggest that what predicts knowledge sharing behaviors depends on the type of knowledge sharing behavior when considering why people share their knowledge through intra-organizational broadcast media. We explore theoretical implications and future research avenues

Between eternity and actualization: the co-evolution of the fields of communication in the Vatican

Most research on structuration or the appropriation of ICT in organizations has put aside the problem of dyschronies. It has not taken into account the differences in nature, speed, and temporality of changes that co-exist within an organization. To address this limitation, the author of this paper suggests a model based on the theory of practice and neo-institutionalist perspectives, so as to make sense of the co-evolution of intra-organizational fields. This model, which proposes a balance between various institutional tensions, has been worked out inductively from a longitudinal case study on communication fields within the Roman Curia, the administrative headquarters of the Catholic Church located in the Vatican. These tensions are related to socio-technical, socio-theological, socio-organizational, and socio-economic areas. A set of propositions regarding the link between intra-organizational fields and tensions and the relationships between intra-organizational fields (parallel, convergent, and competing evolutions) is proposed.Keywords: Dyschronies; structuration; intra-organizational fields; communication; medias; ICT; Roman Curia

FastPay: High-Performance Byzantine Fault Tolerant Settlement

FastPay allows a set of distributed authorities, some of which are Byzantine, to maintain a high-integrity and availability settlement system for pre-funded payments. It can be used to settle payments in a native unit of value (crypto-currency), or as a financial side-infrastructure to support retail payments in fiat currencies. FastPay is based on Byzantine Consistent Broadcast as its core primitive, foregoing the expenses of full atomic commit channels (consensus). The resulting system has low-latency for both confirmation and payment finality. Remarkably, each authority can be sharded across many machines to allow unbounded horizontal scalability. Our experiments demonstrate intra-continental confirmation latency of less than 100ms, making FastPay applicable to point of sale payments. In laboratory environments, we achieve over 80,000 transactions per second with 20 authorities---surpassing the requirements of current retail card payment networks, while significantly increasing their robustness

Use of Online Social Networking Services from a Theoretical Perspective of the Motivation-Participation-Performance Framework

Social networking services (SNS) are platforms to form and manage personal connections and create a foundation for human relationships. Intending to identify why, how, and for what outcome users use SNS, this study contributes to the body of knowledge on SNS by analyzing how motivation, participation, and performance are related to each other in the SNS context. Drawing on a theoretical perspective of the motivation-participation-performance framework, we identify four significant why motivations (i.e., vertical social, horizontal social, hedonic, and utilitarian motivations), two main ways (how) of participation (i.e., sharing and collaboration), and two ultimate benefits (for what outcome) of SNS use (i.e., personal and job performance). The analyzed results of empirical data collected from SNS users indicate that the identified motivations significantly influence participation in sharing and collaboration activities on SNS and that SNS participation significantly affects personal and professional/job-related performance. This study contributes to theory by providing a multidimensional view of SNS use, its predictors, and its consequences

Impact of Enterprise Social Networking Systems Use on Workplace Knowledge Hiding Behaviour: The Moderating Role of Knowledge Sharing Culture

Organisations are always seeking to find new ways to improve organisational knowledge sharing. However, little research has empirically examined the relationship between enterprise social networking systems (ESNS) use and knowledge hiding behaviour. Drawing from the social exchange theory this paper examines the relationship between ESNS use and workplace knowledge hiding behaviour through the moderating role of knowledge sharing culture. The paper analyses data obtained from 289 employees working in the telecommunication and information technology sector in Jordan using a quantitative approach. The findings suggest that ESNS use only reduces knowledge hiding behaviour in organisations with high levels of knowledge sharing culture. For organisations with low levels of knowledge sharing culture, ESNS use had no impact on knowledge hiding behaviour. This study offers a better understanding of ESNS use and its impact on knowledge hiding behaviour in a developing country perspective and also discusses the theoretical and practical implications of the findings.

Enterprise Social Media Use and Impact on Performance: The Role of Workplace Integration and Positive Emotions

Organizations struggle to find ways to improve employees’ performance. To date, little research has empirically examined the relationship between enterprise social media use and knowledge workers’ performance. Using social capital theory and the broaden-and-build theory of positive emotions as our theoretical framework, we investigate the relationship between enterprise social media use and knowledge workers’ performance. We tested our research model by collecting data from employees working for a large information technology firm in the Midwestern United States and analyzing the data using a structural equation modeling approach. The results suggest that enterprise social media use can increase workplace integration, which further enhances performance directly and indirectly through positive emotions. Enterprise social media use also has a direct relationship with performance. The paper concludes with practical and theoretical implications

THE USE OF SOCIAL MEDIA WITHIN ORGANIZATIONS TO FOSTER CONNECTIONS, COLLABORATION, AND KNOWLEDGE SHARING AMONG GEOGRAPHICALLY DISPERSED TEAMS

The study explores how internal social media platforms can help geographically dispersed colleagues become more connected, more collaborative, and more willing to share information. The study findings are based on the analysis of three social media/social networking community “teamsites” available online to three different groups within a global law firm: a Real Estate practice, a women’s affinity group, and a marketing department, in addition to interviews with six participants of such teamsites. Following an interpretive paradigm defined by Sarah Tracy (2013), this study considers Electronic Propinquity Theory, Media Richness Theory, and Social Information Processing Theory by evaluating social media as a communication medium for propinquity and self-disclosure. The findings demonstrate a correlation between heightened propinquity, self-disclosure, knowledge sharing, and collaboration among geographically dispersed teams using a shared teamsite platform

Enterprise social media adoption:Its impact on social capital in work and job satisfaction

Enterprise social media is increasingly being recognized as an important technical tool to achieve more effective management and sustainable development. Limited research has been conducted on workplace satisfaction in the enterprise social media context. To fill this gap, we propose a research model explaininghowemployees' usage of enterprise social media influences job satisfaction from the social capital perspective. Through a survey of 509 respondents, we conceptualize the constructs of enterprise social media use (i.e., work-related use and social-related use), social capital (i.e., bridging social capital and bonding social capital), and job satisfaction. We empirically validate the proposed model. The results largely support the proposed hypotheses. Firstly, both work-related use and social-related use positively impact bridging and bonding social capital. Secondly, bridging and bonding social capital play different roles in job satisfaction. Bonding social capital promotes job satisfaction, while bridging social capital inhibits job satisfaction. Thirdly, work-related use accumulates more bridging social capital, while social-related use is more conducive to the establishment of bonding social capital. Finally, some theoretical and practical implications are discussed.</p
