Photochemical fluorescence activation in arrays of microspherical containers

Responsive Materials, EarlyView.
Photoresponsive microdroplets can be produced with precise structural control from organic solutions of a photoactivatable fluorophore and aqueous solutions of a surfactant at a microfluidic cross junction. These dye‐doped microspheres assemble spontaneously in close‐packed arrays in aqueous media.

Who Can Afford to Fail? Investigating Science Students' Perceptions of Failure Through the Lens of Their Identities

Science Education, EarlyView.
ABSTRACT Scientists agree that learning to cope with failures is an important skill for science students to develop, and students who participate in science research often have positive outcomes after coping with science failures. However, the experience of failure in undergraduate science education more broadly seems to have an overall negative impact

Smuggling Sovereignty: Trade, Transgression, and State Authority

Economic Anthropology, EarlyView.
ABSTRACT Global supply chains are saturated with transgressions—corruption, smuggling, document forgery, and other practices that blur the line between legality and illegality. States do not merely endure these practices; they actively shape the conditions for them, producing the very illegal systems they then claim to police.

Paid‐free differentiation in freemium: Understanding the balance between discovery and cannibalization and its implications for paid product sales

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Entrepreneurs in digital markets often introduce free versions of their paid products to boost their visibility. This freemium strategy involves a trade‐off between discovery and cannibalization. We study how feature‐based differentiation between the paid product and its free version shapes this trade‐off and its consequences ...
