  摘要：Fake news on social media has become a serious problem, and social media platforms have started to actively implement various interventions to mitigate its impact. This paper focuses on the effectiveness of two platform interventions, namely a content-level intervention (i.e., a fake news flag that applies to a single post) and an account-level intervention (i.e., a forwarding restriction policy that applies to the entire account). Collecting data from China's largest social media platform, we...

  摘要：Falls are among the most life-threatening events that challenge senior citizens' independent living. Wearable sensor technologies have emerged as a viable solution for fall detection. However, existing fall detection models either focus on manual feature engineering or lack explainability. To advance the state-of-the-art of wearable sensor-based health management, we follow the computational design science paradigm and develop a deep learning model to detect falls based on wearable sensor data...
• The Effectiveness of Social Norms in Fighting Fake News on Social Media AI翻译

  摘要：Fake news poses a substantial threat to society, with serious negative consequences. Therefore, we investigate how people can be encouraged to report fake news and support social media platform providers in their actions against misinformation. Based on social psychology, we hypothesize that social norms encourage social media users to report fake news. In two experiments, we present participants a news feed which contains multiple real and fake news stories while at the same time exposing the...

  摘要：Easy access to equipment, software, and platforms to create, distribute, and provide access to fake news stories has exacerbated the problem of fake news, making for a large number of highly biased sources that are reaching the mainstream through social networks. The economics of emotion theory proposes that fake news headlines are created to evoke emotional responses in readers that will cause them to interact with the article in a way that allows the creator to make a profit (through clickin...

  摘要：Innovation and competition are two major pillars in the information technology (IT) industry. In this paper, we examine the causal relationship between product market competition and innovations in the IT industry. We measure the innovations from both the quantity (number of patents) and the quality (number of non-self citations) perspectives. Based on the Herfindahl-Hirschman Index and natural experiments, we find robust evidence that the competition has a positive effect on the innovations o...

• Competitive Brokerage: How Information Management Capability And Collaboration Networks Act As Substitutes AI翻译

  摘要：IT-based information management and collaboration networks are both important sources of competitive information. Despite anecdotal evidence, limited research examines their contemporaneous impact on firms' ability to compete effectively. We take an information asymmetry perspective to examine the mechanisms through which the firm's information management capability and the structure of its collaboration network influence the structure of its competition network in product markets. We argue th...
• Monetization Of Digital Content: Drivers Of Revenue On Q&A Platforms AI翻译

  摘要：Valuation of digital content has important individual, organizational, and microeconomic implications. Yet, the existing understanding of digital content consumption is focused primarily on consumption of free content. This means, that digital content is not a source of revenue for contributors and not directly tied to the revenue or expenses of these platforms and that it is practically impossible to capture its value in national income accounts. Academic and anecdotal evidence seems to indic...
• The Effect of the Expressed Anger and Sadness on Online News Believability AI翻译
  作者：Deng, Bingjie; Chau, Michael
  作者单位：University of Hong Kong
  摘要：Emotional expressions have been widely used in online news. Existing research on the perception of online news has primarily focused on the effect of contextual cues on readers' reasoning and deliberation behavior; the role of discrete emotions such as anger and sadness, however, has been overlooked. This paper addresses this research gap by investigating the influence of angry and sad expressions in online news on readers' perception of the news. Drawing on the emotions as social information ...

  摘要：Despite many advantages of social media as a customer service channel, there is a concern that active service intervention encourages excessive service complaints. Our paper casts doubt on this misconception by examining the dynamics between social media customer complaints and brand service interventions. We find service interventions indeed cause more complaints, yet this increase is driven by service awareness rather than chronic complaining. Due to the publicity and connectivity of social ...
