With the advance of information technologies and widespread deployment of data services, users can access social networking sites (SNSs) almost anytime and anywhere, resulting in an incessant urge to check SNSs. Till now, little is known about the precursors of urge and its role in the development of SNS excessive use. Therefore, we proposed and tested a research model that examines the role of urge in checking SNSs. Empirical evidence from a survey of 205 respondents showed that instant gratification and withdrawal are important factors of the urge to check SNSs, the urge to check SNSs was found to have a significant impact on the excessive use. We concluded with implications to research and practice.
Social theories suggest that individuals expect something in return when they decide to share knowledge. These expectations of benefits vary from tangible incentives provided by organizations to positive feelings aroused by altruistic behavior. The theory of consumption values (TCV) allows a specification of distinct types of benefits (functional, social, emotional, epistemic and conditional) which individuals consider before they decide to share knowledge. Furthermore, the perceived costs of sharing can reduce the perceived value of knowledge sharing. These costs are non-monetary sacrifices (effort and risks) reducing the perceived value of sharing.In this work we develop the perceived value of knowledge sharing as a multidimensional construct, grounded in assumptions of social exchange theory, consumer research and knowledge sharing literature. This conceptualization is intended to serve as a basis for the operationalization of perceived knowledge value in a future study on knowledge sharing intentions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
