The Epistemic Generativity of Using a Model of a Big Idea

open access: yesScience Education, EarlyView.
ABSTRACT Science instruction should involve learners in generating and warranting ideas, what we call epistemic generation. In modeling instruction, epistemic generation should be achieved by coordinating a model structure with the experienced world in reciprocal directions denoted as developing models and using models. In the former, a model structure

How digital platforms affect local entrepreneurial activities: Evidence from the staggered entry of craigslist

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Access to markets is critical for entrepreneurial success, yet many face significant barriers. This study argues that digital platforms functioning as peer‐to‐peer marketplaces can facilitate entrepreneurial activity by improving market access for new ventures.

Launch support: Managing complementor bottlenecks in the disruptive innovation of small satellites

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary Through both qualitative and quantitative analyses of large‐rocket providers' support for small‐satellite manufacturers before the emergence of small rockets, we examine how disruptors to an incumbent ecosystem gain support from complementors of the incumbent technology.

Platform competition and strategic trade‐offs for complementors: Heterogeneous reactions to the entry of a new platform

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary We study how the entry of a rival platform affects the strategies of the incumbent's complementors. The latter face a trade‐off: While the entry threatens their benefits from indirect network effects, it also allows them to escape intense within‐platform competition.

Searching together versus searching apart: Evidence from Kaggle

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary How does the mode of search—independently or jointly—affect collective search, a central component of organizational adaptation and innovation? Using naturally occurring data from a strongly incentivized online competition platform, we find that compared to their counterfactuals that search apart, groups searching together ...

Fault Ride-Through Control Strategies of Grid-Forming Inverters Under Grid Faults

open access: yesEducation and Research Archive
Grid-forming (GFM) inverters are increasingly deployed in modern power systems due to their strong voltage and frequency support capabilities, as well as their high robustness in weak grids. However, unlike traditional synchronous generators with high overcurrent tolerance, GFM inverters can only withstand 1 to 1.5 per-unit of their rated current due ...
