The Newsvendor Problem: Review and Directions for Future Research

In this paper, we review the contributions to date for analyzing the newsvendor problem. Our focus is on examining the specific extensions for analyzing this problem in the context of modeling customer demand, supplier costs, and the buyer risk profile. More specifically, we analyze the impact of market price, marketing effort, and stocking quantity on customer demand; how supplier prices can serve as a coordination mechanism in a supply chain setting; integrating alternative supplier pricing policies within the newsvendor framework; and how the buyer’s risk profile moderates the newsvendor order quantity decision. For each of these areas,we summarize the current literature and develop extensions. Finally, we also propose directions for future research

Rhetoric Mining for Fake News: Identifying Moves of Persuasion and Disinformation

We propose a novel Rhetoric Mining methodology to identify moves of persuasion used in disinformation of social media news posts. Rhetoric Mining combines qualitative methodologies and rhetorical theory analysis with machine learning techniques to automatically identify rhetorical moves. Rhetorical moves are instances of discourse intentionally used to persuade an audience. Rhetoric Mining converts the qualitative detection of persuasive moves into quantified rhetoric instance vectors which can be used to characterize rhetorical styles of a text. We identify rhetorical styles of persuasion (news posts with high positive responses, likes, shares, or re-posts) as well as disinformation (news posts that are persuasive but false)

Changing Views: Pre-suasion in a Reddit Discussion Community

Social media allows people to connect and disconnect easily, which leads to more polarization over time. Polarization and the emergence of echo chambers pose a threat to humanity, implying a need to design a healthy social ecosystem in the digital space. Online platforms fostering an environment for good faith discussions and diverse opinions could serve this need. ChangeMyView community of Reddit can be a good example for such an environment because of community-specific characteristics. In this study, utilizing elaboration likelihood model and Cialdini’s pre-suasion, we study the effect of the reward system on individuals’ persuasion mechanisms. Our research design employs a mixed-methods approach in which we investigate (1) the persuasion strategies used in the community and (2) the information processing mechanisms of the community members. We believe that this study will provide insights into potential features of a healthier social ecosystem in digital spaces
