Based on the elaboration likelihood model, means-end chain theory, and gender, this study investigates the effects of the quantity and quality of online reviews, which are mediated by two types of perceived values (utilitarian and hedonic values), on continuance intention to use IOO websites. We further argue that these relationships are moderated by gender. Based on a survey of 291 IOO customers in China, the results suggest that (1) perceived utilitarian and hedonic value completely mediate the positive relationship between online reviews and consumers' continuance intention; (2) through perceived utilitarian value, the indirect effect of the quantity of online reviews on consumers' continuance intention is stronger for females, while the quality of online reviews on consumers' continuance intention is stronger for males; and (3) through perceived hedonic value, the indirect effect of the quantity and quality of online reviews on consumers' continuance intention have no significant difference.

We draw upon the social capital theory in order to discuss how three dimensions of social capital affect consumer value and loyalty to online outshopping platforms. After considering the characteristics of consumers, we propose that the structural, relational, and cognitive dimensions of social capital promote consumers’ perceptions of utilitarian and idea shopping value, and that those perceived values increase loyalty to online outshopping platforms. The survey data of 291 Chinese consumers with online outshopping platform experience are used to test the model. The results show that different dimensions of consumers’ social capital influence their loyalty through different values. Utilitarian value mediates the effects of structural capital and cognitive capital on loyalty, whereas hedonic value (ideal shopping value) mediates the effects of structural and relational capital on loyalty.

Recent Information Systems (IS) publications reveal an emerging interest in studying post-acceptance system usage behaviors. This paper extends the exploitation versus exploration construct to define a new typology of post-acceptance usage behaviors and defines ambidexterity as the capacity to simultaneously achieve exploitative usage and explorative usage. This study examines the relation between exploitation and exploration in IS usage and how the two types of usages can jointly influence individual performance in the post-acceptance stage. Based on a sample of 215 employees, this study finds that exploitative usage and explorative usage have different effects on individual performance, and shows that the interaction between exploitative usage and explorative usage is positively related to individual performance.

Drivers of social commerce usage have been the focus of scholars, but mobile social commerce is currently a sparsely researched area and therefore worth considering. Drawing on the socio-technical systems perspective and attachment theory, this article aims to examine the effect of social and technical enablers on user attachment and whether attachment influences users' shopping and sharing intentions. Results of an empirical study (N=305 active Pinduoduo users) indicate that emotional attachment directly impacts users' intentions, while functional attachment does so indirectly through emotional attachment. Besides, social and technical factors impact emotional and functional attachment, respectively. The study provides further insights about the impact of social and technical factors on attachment and attachment on MSC intention, and contributes to MSC research and practice by developing and validating the role of MSC platforms attributes in forming users' s-commerce behavioral outcomes.

The total amount of waste drugs is expanding significantly as populations age and societies become wealthier. Drug waste is becoming a problem for health and environment. Thus, how to reduce and effectively dispose of waste drugs is increasingly becoming an issue for society. In this paper, we analyze the current situation with regard to existing systems for expired drug recycling and disposal in China and suggest that by connecting the involved practices of waste drug recycling, medication management, and household drug management the incentives to participate in an integrated drug recycling system can be dramatically increased for all involved actors. This is important from an IS perspective because such connecting of practices could account for a novel mechanism of information infrastructure emergence, known from physics as 'state transition'. By contrast, the current literature focuses on the development of information infrastructures through growth at the periphery, mostly driven by user activity and enabled by modular and flexible designs. Our approach could explain the de-novo emergence of an information infrastructure.
