Recent extreme events show that Twitter, a micro-blogging service, is emerging as the dominant social reporting tool to spread information on social crises. It is elevating the online public community to the status of first responders who can collectively cope with social crises. However, at the same time, many warnings have been raised about the reliability of community intelligence obtained through social reporting by the amateur online community. Using rumor theory, this paper studies citizen-driven information processing through Twitter services using data from three social crises: the Mumbai terrorist attacks in 2008, the Toyota recall in 2010, and the Seattle café shooting incident in 2012. We approach social crises as communal efforts for community intelligence gathering and collective information processing to cope with and adapt to uncertain external situations. We explore two issues: (1) collective social reporting as an information processing mechanism to address crisis problems and gather community intelligence, and (2) the degeneration of social reporting into collective rumor mills. Our analysis reveals that information with no clear source provided was the most important, personal involvement next in importance, and anxiety the least yet still important rumor causing factor on Twitter under social crisis situations.
This paper conducts a two-period dynamic analysis of sourcing mode choices for e-commerce projects implemented by large firms during 1999-2002. We differentiate e-commerce assets that are the focus of a sourcing decision in terms of whether they are in the growth or maturity stages. We also consider hybrid governance mechanisms, such as minority equity arrangements, as a potential sourcing mode in addition to the conventional distinction between insourcing (i.e.. hierarchical governance) and outsourcing (i.e., market governance). The rapid evolution in e-commerce technologies and their markets during this period allows us to test whether asset maturity plays any role in sourcing decisions. Results indicate that when the strategic intent of an e-commerce project is more business focused during the growth phase, hybrid governance is preferred over hierarchical governance for sourcing of e-commerce assets. Strategic intent is found not to influence sourcing mode choices during the technology/market maturity phase. Hierarchical governance is the preferred sourcing mode during the growth phase, when task complexity is high. For managing task complexity, as technologies and their markets mature, both hierarchical and hybrid governance modes become preferable to the market governance mode.
