摘要：This paper empirically investigates how review moderation transparency affects the volume, length, and negativity of reviews. A change to the Yelp platform in 2010, introducing review moderation and displaying filtered reviews, created a natural experiment. We used a panel dataset of online reviews from the same set of restaurants on both the Yelp and TripAdvisor platforms in a difference-in-differences (DID) model to test how review moderation transparency affected our outcome variables. We f...

摘要：There is a growing interest in understanding the role of genetics in explaining heterogeneity in behaviors, including those related to information systems (IS). The majority of the recent genetics research focuses on searching the entire genome in genome-wide association studies (GWASs) to link DNA to human traits. The results of GWASs can be used on datasets to compute a measure of genetic propensity known as a polygenic score, or PGS. PGSs are widely viewed as the future of genetics research...

摘要：The COVID-19 pandemic forced organizations, including higher education institutions, to rapidly adjust their operations. In the face of the pandemic, most higher education institutions shut down their campuses and transitioned to emergency remote teaching mode. This study examines digital resilience in higher education institutions through the conceptual lens of disaster response management, by assessing the role played by the centralized governance of information technology (IT) investments. ...

摘要：Many information technology (IT) projects in the U.S. federal government have been plagued with failures and overruns in recent years, wasting a large amount of tax revenues and undermining the public's confidence in the government's ability to manage such resources and deliver on its commitments. What affects the performance of IT projects in the federal government? We find that prior literature on IT project management from the private sector setting is inadequate to answer this question. In...

摘要：This study examines the impact of coordination capabilities provided by enterprise systems (ES), manifested in ES standardization and extensiveness, on merger and acquisition (M&A) outcomes in the short and long term. Specifically, we examine the extent to which the ES standardization and ES extensiveness of the acquiring and target firms contribute to value creation in M&A initiatives. We also study the relationship between the ES standardization and ES extensiveness of the acquiring and targ...

摘要：The sales effect of product reviews has been a contentious issue with competing perspectives about when product reviews serve as a benefit, a burden, or a trifle. Unlike previous research that separately investigates the impact of each eWOM system, our study empirically examines the interaction effects of dual eWOM systems, i.e., product reviews and seller reputation. Drawing on reference point theory, we find that seller reputation systems play a reference-point role and determine the efficac...

摘要：It has been argued in recent years that software is a significant value-creating factor within the manufacturing sector, leading to an increased interest in understanding the mechanisms by which firms may benefit from software-based innovation. Empirical work in evaluating these mechanisms, however, remains underdeveloped. In this paper, we examine one such process through which software-based innovation may provide value for information technology hardware firms in the U.S. Specifically, we e...

摘要：The explosive spread of false news on social media has severely affected many areas such as news ecosystems, politics, economics, and public trust, especially amid the COVID-19 infodemic. Machine intelligence has met with limited success in detecting and curbing false news. Human knowledge and intelligence hold great potential to complement machine-based methods. Yet they are largely underexplored in current false news detection research, especially in terms of how to efficiently utilize such ...

摘要：It has been argued that the theory borrowing practices in IS research have become workmanlike- appropriate and effective, but lacking innovation. This concern is particularly salient at a time when digital phenomena are profoundly transforming society. Therefore, it is legitimate to ask: Are our theory borrowing practices hampering our ability to grapple with revolutionary developments in IS, and if so, what can be done? Through an investigation of the field's borrowing of transaction cost eco...

摘要：Online retailers use product ratings to signal quality and help consumers identify products for purchase. These ratings commonly take the form of either non-personalized, aggregate product ratings (i.e., the average rating a product received from a number of consumers suchas the average rating is 4.5/5basedon100 reviews),or personalizedpredicted preference ratings for a product (i.e., recommender-system-generated predictions for a consumer's rating of a product such as we think you'drate thisp...
