Characteristics, Motivators, and Enablers of Educators Who Earn Many Micro‐Credentials
Future in Educational Research, EarlyView.ABSTRACT This study explores the characteristics, motivators, and enablers of US educators, who earned more than ten micro‐credentials. Although research exists on attitudes and motivators associated with educators newly engaging with micro‐credentials, it lacks insights into learners earning many micro‐credentials.

New Caledonian crows keep ‘valuable’ hooked tools safer than basic non-hooked tools
eLife, 2021 The temporary storage and re-use of tools can significantly enhance foraging efficiency. New Caledonian crows in one of our study populations use two types of stick tools – hooked and non-hooked – which differ in raw material, manufacture costs, and ...

Health Economics, EarlyView.ABSTRACT Evidence on the relationship between public health expenditure and health is mixed and particularly scarce for low‐income countries. Existing studies overlook the subnational distribution of expenditure and rarely distinguish between sources and governance over funding.

Nature Communications, 2023 Tools enable animals to exploit and command new resources. However, the neural circuits underpinning tool use and how neural activity varies with an animal’s tool proficiency, are only known for humans and some other primates.

Laser &Photonics Reviews, EarlyView.Introducing dynamical dephasing into the photon modes of a waveguide causes spontaneous emission to switch from conventional exponential decay to a robust power‐law behavior visible at short times. The power law arises from photon diffusion in a dynamically disordered environment, uncovering a previously unexplored, decoherence‐induced pathway to ...

Laser &Photonics Reviews, EarlyView.A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Dispersion of coupled mode-gap cavities [PDF]
, 2015 The dispersion of a CROW made of photonic crystal mode-gap cavities is pronouncedly asymmetric. This asymmetry cannot be explained by the standard tight binding model.
