The effect of flipped learning on students’ basic psychological needs and its association with self-esteem

Autor: Esma I. Avakyan, David C. M Taylor

Publikováno v: BMC Medical Education, Vol 24, Iss 1, Pp 1-11 (2024)

Abstract Background Modification of the learning environment enhances academic performance, and meta-motivational skills. Yet it is largely unknown which underlying cause potentiates these effects. The study’s goal is to analyse flipped classroom (

XRBcats: Galactic High Mass X-ray Binary Catalogue

Autor: Neumann, Marvin, Avakyan, Artur, Doroshenko, Victor, Santangelo, Andrea

We present a new catalogue of high mass X-ray binaries (HMXBs) in the Galaxy that we call the Galactic High Mass X-ray Binary Catalogue (XRBcats), which improves upon the most recent of such catalogues. We include new HMXBs discovered since previous
