Optimization of dynamic product offerings on online marketplaces: A network theory perspective (2023)
Journal Article
Zuo, M., Angelopoulos, S., Ou, C., Liu, H., & Liang, Z. (2023). Optimization of dynamic product offerings on online marketplaces: A network theory perspective. Journal of Management Information Systems, 40(4), 1328-1357. https://doi.org/10.1080/07421222.2023.2267314

The fierce competition amongst brands on online marketplaces makes the optimization of offerings within this context a significant challenge. To address this challenge, we draw upon network theory and model the degree of competition through consumers...

Big data-driven theory building: Philosophies, guiding principles, and common traps (2023)
Journal Article
Kar, A., Angelopoulos, S., & Rao, H. (online). Big data-driven theory building: Philosophies, guiding principles, and common traps. International Journal of Information Management, 71, Article 102661. https://doi.org/10.1016/j.ijinfomgt.2023.102661

While data availability and access used to be a major challenge for information systems research, the growth and ease of access to large datasets and data analysis tools has increased interest to use such resources for publishing. Such publications,... Read More about Big data-driven theory building: Philosophies, guiding principles, and common traps.

Navigating Digital Transformation through an Information Quality Strategy: Evidence from a Military Organization (2023)
Journal Article
Struijk, M., Angelopoulos, S., Ou, C., & Davison, R. (2023). Navigating Digital Transformation through an Information Quality Strategy: Evidence from a Military Organization. Information Systems Journal, 33(4), 912-952. https://doi.org/10.1111/isj.12430

The use of digital technologies for extracting information from various data sources can help organizations to reduce uncertainty and improve decision-making. The increasing availability in volume, velocity, and variety of data, however, can give ris...

From Groups to Communities: A Resource Mobilization Theory Perspective on the Emergence of Communities (2023)
Journal Article
Angelopoulos, S., Canhilal, K. S., Canhilal, S., & Hawkins, M. A. (2023). From Groups to Communities: A Resource Mobilization Theory Perspective on the Emergence of Communities. Information Systems Frontiers, 25(6), 2457-2474. https://doi.org/10.1007/s10796-023-10368-8

Groups and communities have been key topics in the information systems (IS) research agenda. While communities are assumed to emerge at the intersection of overlapping groups and their practices, prior research has mainly focused on their dynamics an...
