摘要：As a remedy against fake news on social media, we examine the effectiveness of three different mechanisms for source ratings that can be applied to articles when they are initially published: expert rating (where expert reviewers fact-check articles, which are aggregated to provide a source rating), user article rating (where users rate articles, which are aggregated to provide a source rating), and user source rating (where users rate the sources themselves). We conducted two experiments and ...

摘要：During an online session, a user may visit a number of websites, often following hyperlinks from one website to the next or using a search results page to find and visit pages of interest. In doing so, the user can lose track of which sites were visited and which were helpful in meeting the objective. Thus, sites that may have provided value to the user may not receive expected positive effects such as loyalty and intention to return. It is thus crucial to understand if and how an individual w...

摘要：We study how consumers decide which tariff plan to choose and whether to churn when their friends churn in the mobile industry. We develop a theoretical model showing conditions under which users remain with their carrier and conditions under which they churn when their friends do. We then use a large and rich anonymized longitudinal panel of call detailed records to characterize the consumers' path to death with unprecedented level of detail. We explore the structure of the network inferred f...

摘要：To increase transparency of healthcare quality, the Centers for Medicare and Medicaid Services (CMS) initiated the Physician Quality Reporting System (PQRS). However, the impact of PQRS on physicians is unclear, particularly as related to their online reputation. Is there an association between a physician?s online reputation and her adherence to clinical guidelines stipulated in the PQRS? Is online reputation associated with use of electronic health records (EHR)? To investigate these questio...

摘要：We develop a method to assess the quality of peer-produced content in knowledge repositories using their development and coordination histories. We also develop a process to identify relevant features for quality assessment models and algorithms for processing datasets in large-scale knowledge repositories. Models using these features, on English language Wikipedia articles, outperform existing methods for quality assessment. We achieve an overall accuracy of 81 percent which is a 7 percent im...

摘要：Social media platforms disseminate a massive volume of user-generated content, some of which convey similar and overlapping information. We study how the diffusion of a given piece of content (called a cascade) is influenced by the diffusion of other cascades carrying similar content (called parallel cascades). We theorize that the diffusion of a cascade can be inhibited or amplified by that of parallel cascades containing similar content. To study this phenomenon, we formulate a generalized v...

摘要：Gesture-based interaction has greatly changed the way in which we interact with online products by allowing users to control digital systems with hand movements. This study investigates how gesture-based interaction modes, namely, mid-air gesture and touchscreen gesture, compared with mouse-based interaction, affect consumers' virtual product experiences (VPE) by eliciting mental imagery (i.e., haptic imagery and spatial imagery). Furthermore, we explore how visual product presentation can be ...

摘要：Not only is social media a new channel to obtain financial market information, it has also become a venue for investors to share and exchange investment ideas. We examine the performance consequences of providing monetary incentive to both existing and new amateur analysts on social media and its implications for online investor communities. We find that monetary incentive is effective in increasing the amount of content output and generating more interest from the community, but it leads to n...
