The sensory upgrading facilitated by live platforms, such as YouTube Live, Twitch, and Periscope, can facilitate much better interactions and understanding between a product, its brand, and the user. The question of how to enhance sustainable marketing effects using exterior design is currently a major topic in the live streaming marketing sector. The effect of the exterior design of a live platform on the impulse purchases of its consumers has rarely been discussed by academic research. Accordingly, based on the theory of self-determination, this study explored the direct effects of exterior design, self-efficacy, psychological ownership, and impulse buying by using multiple linear regression, and examined the indirect effects of these variables using the structural equation model. In this study, 534 samples were collected from live consumers, and our hypotheses were verified by employing hierarchical regression. As revealed from the results obtained, the self-efficacy and psychological ownership exhibited by consumers exerted synchronous and chain mediating effects on the relationships between the exterior design of the platform and consumer impulse buying. To enhance this marketing effect, live platforms should focus on designing pleasant exterior clues, creating a better psychological atmosphere, and the enhancement of consumers’ self-efficacy.

Based on the affective events theory, this paper discusses the influence of job insecurity on employees’ extra-role behavior. The mediating effect of negative emotion and the moderating effect of workplace friendship are also tested. The results of an empirical analysis, based on the data of 327 employees, show that job insecurity has a significant negative impact on employees’ extra-role behavior. Negative emotion plays a mediating role in the relationship between job insecurity and extra-role behavior. Workplace friendship moderated the relationship between job insecurity and negative emotions, as well as between job insecurity and extra-role behavior. Workplace friendship also moderates the mediating effect of negative emotion on the relationship between job insecurity and extra-role behavior, that is, the higher the level of the workplace friendship is, the weaker the mediation role mentioned above will be. The research results have implications for the sustainable development of the organization.
