Consumers' motivation for photograph posting as a taste expression practice on social media platforms from an offline aesthetic perspective has been neglected in the literature. We explored the influential mechanisms in this relationship using positive emotional arousal and self-expression
as mediators and centrality of visual servicescape aesthetics as a moderator. Data were collected from 273 consumers who had recently dined in well-designed restaurants in China and used social media. The results support the direct and indirect role of offline aesthetic design in consumers'
formation of the intention to post photographs of their dining ambience on social media, and the partially moderating role of their aesthetic trait. Theoretical and practical implications for hospitality management and social media research are discussed.

If consumers like the music in an advertisement, this is conducive to their forming a positive response. To find out what kinds of advertising music people like we conducted semistructured in-depth interviews with 20 participants in China, then analyzed the content through thematic
analysis. We found that consumers liked music that they perceived as having good advertising functions, acceptable artistic qualities, attractive characteristics (e.g., interesting, positive, easy to remember, distinctive), and which had the ability to evoke positive affect and feelings. This
study supplements previous investigations into advertising music from the perspective of consumers. On the basis of our findings, we provide suggestions on selecting music for advertisements that consumers find likable.

Excitonic coupling, electronic coupling, and cooperative interactions in self-assembled lead halide perovskite nanocrystals were reported to give rise to a red-shifted collective emission peak with accelerated dynamics. Here we report that similar spectroscopic features could appear as a result of the nanocrystal reactivity within the self-assembled superlattices. This is demonstrated by studying CsPbBr3 nanocrystal superlattices over time with room-temperature and cryogenic micro-photoluminescence spectroscopy, X-ray diffraction, and electron microscopy. It is shown that a gradual contraction of the superlattices and subsequent coalescence of the nanocrystals occurs over several days of keeping such structures under vacuum. As a result, a narrow, low-energy emission peak is observed at 4 K with a concomitant shortening of the photoluminescence lifetime due to the energy transfer between nanocrystals. When exposed to air, self-assembled CsPbBr3 nanocrystals develop bulk-like CsPbBr3 particles on top of the superlattices. At 4 K, these particles produce a distribution of narrow, low-energy emission peaks with short lifetimes and excitation fluence-dependent, oscillatory decays. Overall, the aging of CsPbBr3 nanocrystal assemblies dramatically alters their emission properties and that should not be overlooked when studying collective optoelectronic phenomena nor confused with superfluorescence effects. ; The work of D.B. was supported by the European Union's Horizon 2020 research and innovation program under the Marie Sklodowska-Curie Grant Agreement No. 794560 (RETAIN).
