摘要：This study examines how affect influences self-disclosure on social network (SN) websites. We test two competing models that build on direct causation theory and affect heuristic theory, respectively. In a direct effect model, affect steers self-disclosure, independent of cognitive cost-benefit appraisals. The indirect effect model instead suggests that affect influences self-disclosure by adjusting perceptions of benefits and costs. The empirical comparison of the models relies on survey data...

摘要：We study how the knowledge that software developers receive from other software developers in their company impacts their performance. We also study the boundary conditions of this relationship. The results of our empirical study indicate that receiving knowledge from other software developers in the company is positively related to the performance of the knowledge-receiving software developers. Moreover, this relationship was stronger when the software developers had high rather than low task...

摘要：Market surveillance systems (MSSs) are information systems that monitor financial markets to combat market abuses. Existing MSSs focus mainly on analyzing trading activities and are often developed through a trial-and-error approach by screening data mining algorithms and features. The void of theoretical direction limits the effectiveness of MSSs and calls for the development of a design theory based on a thorough examination of the meta-requirements of MSSs. Based on the efficient market hyp...

摘要：Young Internet users engage in risky or inappropriate behavior online that could either be embarrassing or harmful to their future. As importantly, young Internet users engage in online activities that reveal a great deal about the cost to serve them and their willingness to pay for goods and services, which could be used against them by well-informed sellers. Educational applications that collect users' information are becoming ubiquitous in the classroom, presenting the opportunity for stude...

摘要：Motivated by the wide dispersion in the returns on the use of information technology (IT) across industries, we conduct an industry-level examination of IT return and risk, focusing on the moderating role of industry competition, regulation, and technological change. We address the following research questions: What is the impact of IT investment on the return and risk dimensions of industry financial performance? How do industry characteristics moderate the relationship between IT investment ...

摘要：Community-based question-and-answer (Q&A) websites have become increasingly popular in recent years as an alternative to general-purpose Web search engines for open-ended complex questions. Despite their unique contextual characteristics, only a handful of Q&A websites have been successful in sustaining members' active participation that, unlike lurking, consists of not only posting questions but also answering others' inquiries. Because the specific design of the information technology artifa...

摘要：Despite the potential benefits, many organizations have failed in service-oriented architecture (SOA) implementation projects. Prior research often used a variance perspective and neglected to explore the complex interactions and timing dependencies between the critical success factors. This study adopts a process perspective to capture the dynamics while providing a new explanation for the mixed outcomes of SOA implementation. We develop a system dynamics model and use simulation analysis to ...

摘要：Data breach incidents are on the rise, and have resulted in severe financial and legal implications for the affected organizations. We apply the opportunity theory of crime, the institutional anomie theory, and institutional theory to identify factors that could increase or decrease the contextual risk of data breach. We investigate the risk of data breach in the context of an organization's physical location, its primary industry, and the type of data breach that it may have suffered in the p...

摘要：Advances in information technology bring changes to the nature of work by facilitating companies to go beyond the wisdom of their workforce and tap into the wisdom of the crowd via online crowdsourcing contests. In these contests, active and motivated individuals collaborate in the form of self-organized teams that compete for rewards. Using a rich data set of 732 teams in 52 contests collected from the crowdsourcing platform, Kaggle.com, from its launch in April 2010 to July 2012, we studied ...
