Live streaming technologies transform the information processing of customers by changing the way they interact with and acquire information. However, this emerging technological artefact may induce both positive and negative consequences for customer decision making. It is yet unknown what constitutes the dimensions of the juxtaposed IT affordances and how they affect customer behaviours in this new social phenomenon. This paper contributes to IS research by uncovering the specific bright and dark sides of IT affordances in live streaming e-commerce and by explaining the cognitive mechanisms underpinning customer purchase and brand citizenship behaviours. We employed a sequential mixed-methods design to embrace and contextualise the theory of affordance, vicarious learning, and cognitive load to rigorously develop a theoretical framework of the juxtaposed IT affordance in live streaming e-commerce. The results indicate that positive affordances (e.g., interactivity, visibility, and entertainment) have stronger effects on both economic and non-economic value. However, the potential dark side (e.g., broadcasting and source diversity) has more negative effects on purchase intention than brand citizenship behaviour, underscoring the importance of involving customers in co-creating brand-related value in live streaming e-commerce. Our findings contribute considerably to the emerging literature on live streaming e-commerce and provide actionable recommendations for practitioners.

This research developed an effective supply chain management (SCM) operation model and a corresponding diagnostic methodology in the global competitive environment by combining three phases and methodologies. In Phases 1, a list of impact factors was collected from relevant studies, and a hierarchy for the current complex research issue was established. In Phase 2, an expert survey was conducted for enhancing the content effectiveness of the model. Subsequently, an analytic hierarchy process (AHP) was applied to determine the weights of those factors. In Phase 3, a self-assessment framework was developed to examine the effectiveness of the global SCM. Finally, a case was analyzed to verify the effectiveness of the self-assessment scales. The results show that the concept of global SCM tends to be broader and more comprehensive than traditional one. Especially in the coordination and cooperation between market, organization itself and suppliers, while using information technology as a communication tool.

The online banking service is the key element for the development of e-commerce and e-businesses. It provides users with convenient daily transaction services, such as wire transfer and online payment. Past studies on online banking services mostly focused on their functionality, whereas little pay attention to users’ hedonic feelings or a sense of pleasure. Besides, discussions about post-adoption behavior are also immature. Thus, this study aims to explore the impacts of customers' positive or negative experience of using online banking services on consumers' emotions. Furthermore, a discussion of post-adoption behaviors, including recommendations, complaints, and continuance intention is also provided. The result shows that positive user experience will have a significantly positive impact on the generation of utilitarian emotion. As for the sense of utilitarian emotion, users concern more about whether their goal could be achieved successfully via their operations or not, such as completing wire transfer transactions in the online banking environment.
