  摘要：If managers assume a normal or near-normal distribution of Information Technology (IT) project cost overruns, as is common, and cost overruns can be shown to follow a power-law distribution, managers may be unwittingly exposing their organizations to extreme risk by severely underestimating the probability of large cost overruns. In this research, we collect and analyze a large sample comprised of 5,392 IT projects to empirically examine the probability distribution of IT project cost overruns...
• Why do Family Members Reject AI in Health Care? Competing Effects of Emotions AI翻译
  作者：Park, Eun Hee; Werder, Karl; Cao, Lan; Ramesh, Balasubramaniam

  摘要：Artificial intelligence (AI) enables continuous monitoring of patients' health, thus improving the quality of their health care. However, prior studies suggest that individuals resist such innovative technology. In contrast to prior studies that investigate individuals' decisions for themselves, we focus on family members' rejection of AI monitoring, as family members play a significant role in health care decisions. Our research investigates competing effects of emotions toward the rejection ...
• Rethinking Project Escalation: An Institutional Perspective on the Persistence of Failing Large-Scale Information System Projects AI翻译

  摘要：Project escalation involves the continued, persistent commitment to a failing project. Through a qualitative meta-analysis of 15 published cases of large information systems (IS) projects in escalation situations, we develop an institutional perspective on IS projects in escalation situations. This perspective describes how project persistence emerges from a plurality of legitimizing institutional logics that decision-makers draw upon at different project stages to maintain and reduce their co...
• User Comments in Social Media Firestorms: A Mixed-Method Study of Purpose, Tone, and Motivation AI翻译
  作者：Matook, Sabine; Dennis, Alan R.; Wang, Yazhu Maggie

  摘要：Social media firestorms (SMF) are commonly seen as destructive forces of toxic comments hurled at a target for perceived wrongdoing. Yet some research suggests that SMF can provide beneficial outcomes for the target. In two studies, we qualitatively examine SMF comments (in terms of purpose and tone) and quantitatively examine users' motivations for making different types of comments. Results show that SMF comments are diverse, either supporting or condemning the target and being either aggres...
• Piracy and Bundling of Information Goods AI翻译

  摘要：Bundling is considered to be an effective pricing strategy for zero-marginal-cost information goods. Yet, in many information-goods markets, the effectiveness of bundling remains hard to ascertain. This is because information goods exhibit other characteristics as well, which can potentially interfere with a manufacturer's bundling decision. For instance, they are also prone to piracy, and it is not obvious what impact, if any, piracy can have on the efficacy of bundling. To address this issue...

• Improving Phishing Reporting Using Security Gamification AI翻译
  作者：Jensen, Matthew L.; Wright, Ryan T.; Durcikova, Alexandra; Karumbaiah, Shamya
  作者单位：University of Oklahoma System; University of Oklahoma - Norman; University of Virginia; Carnegie Mellon University
  摘要：Phishing is an increasing threat that causes billions in losses and damage to productivity, trade secrets, and reputations each year. This work explores how security gamification techniques can improve phishing reporting. We contextualized the cognitive evaluation theory (CET) as a kernel theory and constructed a prototype phishing reporting system. With three experiments in a simulated work setting, we tested gamification elements of validation, attribution, incentives, and public presentatio...
• Peer-To-Peer Rentals, Regulatory Policies, And Hosts' Cost Pass-Throughs AI翻译
  作者：Mueller, Michelle; Neumann, Juergen; Kundisch, Dennis
  作者单位：University of Paderborn
  摘要：Peer-to-peer (P2P) rental markets have been shown to adversely impact the traditional hospitality industry and housing affordability, fueling the public demand for regulation. While localities around the globe have implemented policies to address these issues, little is known about how rental suppliers respond to those regulations. This study aims to empirically analyze the impact of such policy regulations on the prices charged by different types of rental suppliers. We employed a quasi-exper...
• The Impact of Trust and Recommendation Quality on Adopting Interactive and Non-Interactive Recommendation Agents: A Meta-Analysis AI翻译
  作者：Ebrahimi, Sepideh; Ghasemaghaei, Maryam; Benbasat, Izak
  作者单位：York University - Canada; McMaster University; University of British Columbia
  摘要：Research on recommendation agents (RAs) originally focused on interactive RAs, which rely on explicit methods, i.e., eliciting user-provided inputs to learn about consumers' needs and preferences. Recently, due to the availability of large amounts of data about individuals, the focus shifted toward non-interactive RAs that use implicit methods rather than explicit ones to understand users' needs. This paper examined the differences between interactive and non-interactive RA types in terms of h...
• The Good, the Bad, and the Social Media: Financial Implications of Social Media Reactions to Firm-Related News AI翻译

  摘要：Firms and investors often react to financial news on social media. However, how they react to news of different nature and whether their reactions influence the stock market is far from clear. Employing data on financial news, tweets posted by firms and investors, and daily stock prices, we find that firms are more responsive to news with positive sentiment and low uncertainty, whereas investors are more responsive to news with high uncertainty. Moreover, the increased tweeting activities of f...
