摘要:The digitalization of organizational settings can provide seemingly unprecedented visibility into knowledge work practices through trace data. Although trace data could be a boon for monitoring knowledge work that has traditionally eluded detailed oversight, the broader literature on data suggests that increasing behavioral visibility through trace data can also motivate reactions that reduce the transparency of work practices and question the validity of the data. To reconcile these contrasti...

摘要:Review-in-review (RIR) is a feature that allows viewers to generate positive or negative evaluations for primary quality evaluations of a product (e.g., ratings and reviews). This feature has the potential to reshape primary quality evaluations; specifically, it can cause social desirability bias in ratings, as raters (i.e., reviewers) who desire social recognition might be driven to provide ratings that are expected to gain more helpful and avoid unhelpful RIRs. This study aims to isolate thi...

摘要:To reduce the availability of hacking tools for use in cybersecurity offenses, many countries have enacted computer misuse acts (CMAs) that criminalize the production, distribution, and possession of such tools with criminal intent. However, the dual-use nature of cybersecurity technology complicates the legal process of recognizing such computer misuse tools and of predicting harmful intent based on mere possession. This predicament introduces the possibility of unfounded prosecution that may...

摘要:Disaster relief organizations (DROs) utilize social media to provide information rapidly and broadly. Many DROs post content via multiple social media accounts within a single platform, on which each account represents a distinct entity (e.g., national headquarters, local branch). According to crisis communication theory, an organization's communication channels can coordinate by speaking with one voice. In a disaster context, this can be facilitated by accounts within the same DRO producing c...

摘要:This paper presents methods to choose individuals to test for infection during a pandemic such as COVID-19, characterized by high contagion and presence of asymptomatic carriers. The smart-testing ideas presented here are motivated by active learning and multi-armed bandit techniques in machine learning. Our active sampling method works in conjunction with quarantine policies, can handle different objectives, and is dynamic and adaptive in the sense that it continually adapts to changes in rea...

摘要:Whereas modern medicine has enabled humans to live longer and more robust lives, recent years have seen a significant increase in chronic care costs. The prevention of threats to mobility, such as falls, freezing of gait, and others, is critical for chronic disease management. Researchers and physicians often analyze data from wearable motion sensor-based information systems (IS) to prevent falls because of their convenience, low cost, and user privacy protection. However, prior studies on fal...

摘要:This paper proposes a smart ad display system to provide personalized delivery of video ads. The proposed system records consumers' facial expression and eye gaze stream data as they watch an ad and analyzes data at the frame level. The recognized facial expression and detected eye gaze are matched to the corresponding frame of the video ad, thereby linking facial expressions to specific visual objects appearing in the ad. By tracking a consumer's facial expressions in response to various visu...

摘要:Although the effects of algorithmic product recommendations on product sales are understood, the differential effects of retargeted recommendations (recommended products a user has previously viewed) versus generic recommendations (recommended products a user has not previously viewed) are unclear. We conduct a field experiment to empirically examine the relative effect of retargeted versus generic recommendations on product sales at different stages of users' purchase funnel. The product reco...

摘要:Millions of users on the Internet have fallen into phishing website traps. Detection tools are designed to warn users against such attacks but often fail to achieve this purpose due to usability issues. To address these issues and increase user self-protection against such attacks, we propose an ontology-based intelligent interface personalization (OBIIP) design for the warning interfaces of phishing website detection tools. Our design involves two phases: proof-of-concept and proof-of-value. ...

摘要:Many online communities that rely on effortful, voluntary content contributions offer additional content curation tools to facilitate social interactions and encourage user contributions. Any platform that offers two or more heterogeneous content types (e.g., expert knowledge and social posts) faces a choice about the presentation format: whether to display the content types separately or in an integrated information feed. We leverage a natural experiment on Zhihu, a Q&A platform that offers a...
