How social and media cues induce live streaming impulse buying? SOR model perspective.

Live streaming is revolutionizing the landscape of e-commerce, creating new opportunities for platforms and e-tailers to improve their performance. However, little is known about the underlying mechanisms that shape consumer behavior in this burgeoning business phenomenon. This study aims to shed light on the relationships between environmental cues generated by live streaming and online impulse buying.

Clinical and epidemiological investigation of a child with asymptomatic COVID-19 infection following reoccurrence.

Objective: To investigate the case of a child infected with coronavirus disease 2019 (COVID-19) who had subsequent viral reactivation.

Methods: We retrospectively analyzed the clinical manifestations, epidemiological data, laboratory and imaging examinations, treatment, and follow-up of the child. And then, we searched related literature using PubMed.

Guest-dependent directional complexation based on triptycene derived oxacalixarene: formation of oriented rotaxanes.

The manipulation of supramolecular devices to carry out sophisticated and programmed tasks is bound up with the spatial allocation of their components, especially the threading direction of the guest, which controls the host-guest orientation in the device. However, insights are needed to probe more possibilities for steering the threading direction. We have developed a new system consisting of a three-dimensional nonsymmetric oxacalixarene () with a fixed comformation and (bi)pyridinium salts (), in which we found that based on the intrinsic discrepancies between the two semi-cavities of , the electron densities of the axles greatly affect the threading direction.
