摘要：Whatever answer one gives to the question Is information technology changing the world?, the answer contains reasoning about causality. Causal reasoning is central to IS theorizing. This paper focuses on the concept of causal structure, defined by Markus and Robey (1988) as a theorist's assumptions about causal influences in IS phenomena, and proposes a framework of causal structure, warranted by philosophy and social theory, specialized for the needs of Information Systems scholars. The three...

摘要：In this article, an evolutionary argument to explain how people comprehend graphs is put forth. A theory of evolutionary fit, which argues for the correspondence between information presentation and evolutionarily adaptive brain structures, is proposed. This is complementary to cognitive fit, which argues for a correspondence between task and information presentation. In two fMRI experiments, we test this theory by comparing brain activation during a graphic comprehension task using two differ...

摘要：It has been often suggested that much of the widespread use of economic experiments has been possible only because of the developments in information technology. Yet, the information systems (IS) domain has been largely lagging in its use of the methodology. This commentary is aimed at spurring the use of economic experiments in the IS domain by explaining the advantages of the methodology, and by defining its norms for the benefit of both the authors as well as the reviewers.

摘要：Crowdsourcing contests have emerged as an innovative way for firms to solve business problems by acquiring ideas from participants external to the firm. As the number of participants on crowdsourcing contest platforms has increased, so has the number of tasks that are open at any time. This has made it difficult for solvers to identify tasks in which to participate. We present a framework to recommend tasks to solvers who wish to participate in crowdsourcing contests. The existence of competit...

摘要：Understanding the degree of cannibalization and competition in online and offline markets is important to firms' product line designs. However, few empirical studies have measured both effects simultaneously or have examined the factors that determine the extent of cannibalization and competition. In this study, we develop an empirical model to identify cannibalization and competition effects simultaneously in different markets, and further examine the impacts of consumer preferences on these ...

摘要：Work interruptions have made significant inroads into the knowledge workers' nonwork domain, in large part due to the ubiquitous nature of mobile devices that blur the work-nonwork boundaries by enabling work interruptions anywhere and at any time. We examine the effects of such technology-mediated work-related interruptions that occur during one's time off on both work and nonwork outcomes. Leveraging theoretical perspectives from interruption, work-life interface, and conservation of resourc...

摘要：Social media have great potential to support diverse information sharing, but there is widespread concern that platforms like Twitter do not result in communication between those who hold contradictory viewpoints. Because users can choose whom to follow, prior research suggests that social media users exist in echo chambers or become polarized. We seek evidence of this in a complete cross section of hyperlinks posted on Twitter, using previously validated measures of the political slant of new...

摘要：Information spillovers are benefits that a party obtains from the IT efforts of another party. Because these benefits arise from data and information sharing, they are best studied at a process level. Medical claims fraud detection is a prototypical data-and information-intensive process in insurance companies. Fraud detection efforts of one insurer can create spillover benefits through data and information sharing that occur from socialization between analysts and labor mobility between insur...

摘要：Research in the fields of information systems and human-computer interaction has shown that habituation-decreased response to repeated stimulation-is a serious threat to the effectiveness of security warnings. Although habituation is a neurobiological phenomenon that develops over time, past studies have only examined this problem cross-sectionally. Further, past studies have not examined how habituation influences actual security warning adherence in the field. For these reasons, the full ext...

摘要：Outsourcing work relies on the supplier's interpretation of the work delegated by the client. Existing streams of outsourcing literature tend to assume that the supplier should use the same convention as the client to make sense of the work package. In this research, we use a semiotic lens to challenge this assumption by viewing such sensemaking as a process of decoding symbolic representations. This complementary view involves innovative use of digital technology for re-representing the outso...
