摘要：In order to motivate individuals to share their knowledge in online communities, the use of extrinsic rewards and goals is a typical approach. However, extrinsic motivation may have unintended consequences. Although past studies have examined the direct effect of extrinsic motivation on intrinsic motivation, no research to date has investigated how extrinsic motivation moderates the impact of intrinsic motivation on knowledge sharing, or how the effect of extrinsic motivation on intrinsic moti...

摘要：We focus on predicting the profitability of a movie to support movie-investment decisions at early stages of film production. By leveraging data from various sources, and using social network analysis and text mining techniques, the proposed system extracts several types of features, including who is in the cast, what a movie is about, when a movie will be released, as well as hybrid features. Experiment results showed that the system outperforms benchmark methods by a large margin. Novel feat...

摘要：The issue of versioning of information goods has resurfaced, in part as a result of the recent popularity of downloadable contents (DLC) among video game manufacturers. The central idea behind the DLC strategy, zero-day DLCs in particular, is that consumers who find the base version of a game to be sufficiently close to their tastes would want more of its capabilities and would pay a premium to upgrade by purchasing a DLC. To better understand the implications of such a product-line strategy, ...

摘要：Real options thinking helps individuals cope with uncertainties in the information technology (IT) investment decision-making process. Our study examines the intertwining of cognition and a specific emotion, regret, in IT real options decision making using a multisite case study of IT investments. We develop a process model that explains the context in which regret is triggered, the strategies used to regulate regret, and how these strategies influence the valuation, creation, exercise, and re...

摘要：In the private sector, research on information technology (IT) governance has frequently applied the classical view of agency theory and focused on the controlling role played by the board of directors in constraining a potentially opportunistic manager/agent. However, in the public sector, the board of directors does not exist and there may be less need to focus on the controlling aspect of governance and more need to focus on the politically challenging distribution of state resources. In th...

摘要：Malicious software, commonly termed malware, continuously presents one of the top security concerns, and causes tremendous worldwide financial losses for organizations. In this paper, we propose a structural risk model to analyze malware propagation dynamics measured by a four-parameter (asymptote, point of inflection, rate, and infection proportion at inflection) growth curve. Using both social network data and technological network infrastructure from a large organization, we estimate the pr...

摘要：This article studies the strategic network formation in a location-based social network. We build an empirical model of social link creation that incorporates individual characteristics and pairwise user similarities. Specifically, we define four user proximity measures from biography, geography, mobility, and short messages. To construct proximity from unstructured text information, we build topic models using Latent Dirichlet Allocation. Using Gowalla data with 385,306 users, 3 million locat...
