摘要：Fake news (i.e., misinformation) on social media has sharply increased in the past few years. We conducted a behavioral experiment with EEG data from 83 social media users to understand whether they could detect fake news on social media, and whether the presence of a fake news flag affected their cognition and judgment. We found that the presence of a fake news flag triggered increased cognitive activity and users spent more time considering the headline. However, the flag had no effect on ju...

摘要：As e-government websites grow in functionalities and capabilities, there is a need to better understand the nuanced role of service quality to enable governments to better address citizens' online service needs. Such an understanding should help improve overall e-government use by citizens. Thus motivated, our paper investigates how users respond to the service quality perception-expectation gap in e-government websites. We draw on rational choice theory (RCT) to develop a theoretical model li...

摘要：Although combinatorial auctions are important mechanisms for many specialized applications, their adoption in general-purpose marketplaces is still fairly limited, partly due to the inherent difficulty in evaluating the efficacy of bids without the availability of comprehensive bidder support. In this paper, we present both theoretical results and computational designs to support real-time feedback to bidders in continuous combinatorial auctions, where bidders are free to join and leave the au...

摘要：Identity theft has impaired e-commerce. To combat the crime, many identity theft countermeasures (ITC) have been proposed. As investments in ITC are substantial and the benefits of such investments are intangible, companies are often hesitant to adopt such measures. This was the motivation for this study of the impact of 526 ITC adoption announcements on short- and long-term market value. The event study shows that such announcements result in positive market return of about U.S. $583 million ...

摘要：Crowdsourcing contests are contests by which organizations tap into the wisdom of crowds by outsourcing tasks to large groups of people on the Internet. In an online environment often characterized by anonymity and lack of trust, there are inherent uncertainties for participants of such contests. This study focuses on crowdsourcing contests with winner-take-all prizes. During these contests, submissions are made sequentially and contest hosts can provide public in process feedback to the submi...

摘要：Wearable devices and applications (apps) that offer a variety of features intended to support exercisers have flooded the marketplace. Organismic integration theory (OIT) proposes that motivations to exercise can vary along a spectrum of self-determination. To best serve exercisers and assist organizations that are developing and promoting fitness technologies, we need a better understanding of how individuals' exercise motivations influence their fitness technology feature set use. We also ne...

摘要：Prior research has shown that online recommendations have a significant influence on consumers' preference ratings and economic behavior. Specifically, biases induced by observing personalized system recommendations can lead to distortions in users' self-reported preference ratings after consumption of an item, thus contaminating the users' subsequent inputs to the recommender system. This, in turn, provides the system with an inaccurate view of user preferences and opens up possibilities of r...

摘要：As people share more of their lives on social media, their consumption and purchase behaviors become increasingly visible to their peers, spawning a new form of digitally enabled conspicuous consumption. We examine how the ensuing dynamics of social commerce affect these visibility choices. We use data from a platform dedicated exclusively to facilitating the display of verified online and offline purchases with optional product commentaries. We use fixed effects and matching techniques to con...

摘要：Individuals increasingly rely on healthcare virtual support communities (HVSCs) for social support and companionship. While research provides interesting insights into the drivers of informational support in knowledge-sharing virtual communities, there is limited research on the antecedents of emotional support provision and companionship activities in HVSCs. The unique characteristics of HVSCs also justify the need to reexamine members' voluntary provisions of help in such communities. This p...

摘要：This study proposes and tests a model that explains and predicts risk response decisions of information technology project managers (ITPMs), blending the domains of the theory of planned behavior (TPB) and behavioral decision theories, and leveraging information technology project risk management behavioral research. The model posits that a risk response decision is indirectly influenced by perceived risk exposure via overall risk response attitude. The model conceptualizes perceived risk expo...
