Recent years have witnessed the rapid proliferation and widespread adoption of a new class of information technologies, commonly known as social media. Researchers often rely on social network analysis (SNA) in attempting to understand these technologies, often without considering how the novel capabilities of social media platforms might affect the underlying theories of SNA, which were developed primarily through studies of offline social networks. This article outlines several key differences between traditional offline social networks and online social media networks by juxtaposing an established typology of social network research with a well-regarded definition of social media platforms that articulates four key features. The results show that at four major points of intersection, social media has considerable theoretical implications for SNA. In exploring these points of intersection, this study outlines a series of theoretically distinctive research questions for SNA in social media contexts. These points of intersection offer considerable opportunities for researchers to investigate the theoretical implications introduced by social media and lay the groundwork for a robust social media agenda potentially spanning multiple disciplines.
This study investigates the effects of information technology (IT) on exploration and exploitation in organizational learning (OL). We use qualitative evidence from previously published case studies of a single organization to extend an earlier computational model of organizational learning (March 1991) by introducing IT-enabled learning mechanisms: communication technology (e-mail), knowledge repositories of best practices, and groupware. We find that each of these IT-enabled learning mechanisms enable capabilities that have a distinct effect on the exploration and exploitation learning dynamics in the organization. We also find that this effect is dependent on organizational and environmental conditions, as well as on the interaction effects between the various mechanisms when used in combination with one another. We explore the implications of our results for the use of IT to support organizational learning.
Firms increasingly turn to online communities to create valuable information. These communities are empowered by new information technology-enabled collaborative tools, tools such as blogs, wikis, and social networks. Collaboration on these platforms is characterized by considerable membership turnover, which could have significant effects on collaborative outcomes. We hypothesize that membership retention relates in a curvilinear fashion to effective collaboration: positively up to a threshold and negatively thereafter. The longitudinal history of 2,065 featured articles on Wikipedia offers support for this hypotheses: Contributions from a mixture of new and experienced participants both increases the likelihood that an article will be promoted to featured article status and decreases the risk it will be demoted after having been promoted. These findings imply that, contrary to many of the assumptions in previous research, participant retention does not have a strictly positive effect on emerging collaborative environments. Further analysis of our data provides empirical evidence that knowledge creation and knowledge retention are actually distinct phases of communitybased peer production, and that communities may on average experience more turnover than ideal during the knowledge retention phase.
This paper argues that Web 2.0 tools, specifically wikis, have begun to influence business and knowledge sharing practices in many organizations. Information Systems researchers have spent considerable time exploring the impact and implications of these tools in organizations, but those same researchers have not spent sufficient time considering whether and how these new technologies may provide opportunities for us to reform our core practices of research, review, and teaching. To this end, this paper calls for the IS discipline to engage in two actions related to wikis and other 1 Carol Saunders was the accepting senior editor for this paper. Web 2.0 tools. First, the IS discipline ought to engage in critical reflection about how wikis and other Web 2.0 tools could allow us to conduct our core processes differently. Our existing practices were formulated during an era of paperbased exchange; wikis and other Web 2.0 tools may enable processes that could be substantively better. Nevertheless, users can appropriate information technology tools in unexpected ways, and even when tools are appropriated as expected there can be unintended negative consequences. Any potential changes to our core processes should, therefore, be considered critically and carefully, leading to our second recommended action. We advocate and describe a series of controlled experiments that will help assess the impact of these technologies on our core processes and the associated changes that would be necessary to use them. We argue that these experiments can provide needed information regarding Web 2.0 tools and related practice changes that could help the discipline better assess whether or not new practices would be superior to existing ones and under which circumstances.
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.
