The Factors Influencing the Idea Recognition of Open Innovation Platforms: Take LEGO Ideas as an Example
With the influx of users posting their ideas to Open Innovation Platforms (OIPs), there has been widespread interest in how companies screen high-quality ideas. Most of the existing literature on idea quality focuses on the adoption of ideas by companies, while ignoring the recognition among users. Based on the ideas posted by users of LEGO Ideas, this study first analyzes the influence of users’ social learning and social network on their innovation ability, and then further investigates the influence of idea authors’ innovation ability and idea content’s characteristics on idea recognition based on signal theory. The findings suggest that more challenging social learning as well as weighted indegree and betweenness centrality of social network positively affect users’ innovation ability and weighted outdegree of social network negatively affects users’ innovation ability. Meanwhile, idea authors’ innovation ability and the number of pictures, text length, richness, popularity, and emotional polarity of idea content positively affect idea recognition. Distinct from the existing literature, this paper focuses on idea recognition among users, delves into the influence of social learning and social network on users’ innovation ability, and integrates the study of factors influencing users’ innovation ability into the study of factors influencing idea recognition
Coherent heteronuclear spin dynamics in an ultracold spin-1 mixture
We report the observation of coherent heteronuclear spin dynamics driven by
inter-species spin-spin interaction in an ultracold spinor mixture, which
manifests as periodical and well correlated spin oscillations between two
atomic species. In particular, we investigate the magnetic field dependence of
the oscillations and find a resonance behavior which depends on {\em both} the
linear and quadratic Zeeman effects and the spin-dependent interaction. We also
demonstrate a unique knob for controlling the spin dynamics in the spinor
mixture with species-dependent vector light shifts. Our finds are in agreement
with theoretical simulations without any fitting parameters.Comment: 13 pages including the supplementary materia
