Post adoptive IT use is an important research topic in information systems field, mainly including sustained behaviours and switching behaviours. While there are a great number of studies on users’ continuance intentions for diversified IT, users’ IT switching behaviours are less studied. This research attempts to identify the features of users IT switching behaviours. We introduce a migration theory from social network perspective to explore the intrinsic and extrinsic factors influencing users’ switching intention in the context of mobile instant messaging (MIM) application. In particular, we develop a model that examines the role of networks, deprivations and trusts on MIM users’ switching intentions to WeChat in China. A survey research method is utilized to test this model and hypotheses. We found that functional deprivation, monetary deprivation and personal innovativeness could positively influence users’ switching intentions. Networks of obligation was found to have no significantly direct influence on switching intentions, but fully mediated by functional and monetary deprivations. However, trust transferred from MIMs provider has no significant effect on switching intentions. The findings are believed to theoretically contribute to further understand users’ IT switching behaviours and yield some practical implications for designers and managers in MIM providers and their products propaganda.

New energy policies (NEPs) have become an effective administrative means to manage the energy market and incentivize the development of the new energy sector. To reveal how and why NEPs are differentially diffused in geographic space, this study proposes a quantitative citation-based approach for exploring NEP diffusion from a spatial-temporal perspective. By identifying a wealth of policy citation links implicit in 7,375 China's NEP documents, we first illustrate spatial structures and locational dynamics of NEP diffusion, while empirically investigating driving factors that shape the spatial-temporal heterogeneity of NEP diffusion. The results indicate that: (i) the top-down pattern is the most critical spatial pattern of NEP diffusion in China, with the highest diffusion speed, diffusion intensity, and policy innovation degree; (ii) NEP diffusion exhibits a rapidly increasing trend, accompanied by the gradually strengthening spatial pattern of the "eastern>central>western"; (iii) some local socioeconomic, contextual, and energy usage conditions are responsible for the spatial heterogeneity of policy diffusion. Our study provides valuable implications for policymakers to strategically craft adequate policy-making and differentiated promotion strategies for new energy sustainability. • This study proposes a citation-based approach for exploring NEP diffusion from a spatial-temporal perspective. • Diffusion speed, diffusion intensity, and innovation degree of NEPs in different regions are quantified. • Spatial structures and locational dynamics of NEP diffusion are revealed. • Non-spatial (OLS) and spatial (MGWR) models are introduced to determine driving factors of NEP diffusion. • Local socioeconomic, contextual, and energy usage conditions are responsible for the spatial heterogeneity of NEP diffusion.

• Scientific crowdfunding campaigns with endorsements have better fundraising and participation performances. • Endorsement genre's analytical framework is constructed, including 2 dimensions and 11 attributes. • The "person-then-project" presentation pattern is superior to the "project-then-person" pattern in the balanced endorsement genre. • A stronger endorsement sentiment induces a better campaign fundraising performance. • The campaigns with a high endorsement sentiment have better fundraising and participation performances. In recent years, endorsers have been involved in many scientific crowdfunding campaigns to improve project progress. While the effectiveness of endorsement has been frequently examined in the marketing field, it lacks in-depth analysis in scientific crowdfunding. To reveal whether and how endorsement influences scientific crowdfunding performance, we employ signaling theory as a theoretical lens and analyze 1,839 campaigns from Experiment.com. First, the result from propensity score matching method indicates that endorsements generally have a positive effect on scientific crowdfunding performance. Using open coding, we refine the endorsement genre's analytical framework, employing 2 dimensions (project-related and person-related) and 11 relevant attributes. The regression results suggest that clearly stating the implications of the project can significantly affect both fundraising and participation performance. The impacts of the endorser's identity and endorser's agreement on the initiator's ability promote fundraising performance, while the research background and condition statement positively contribute to participation performance. Furthermore, we classify scientific endorsements into three genres: project-focused, person-focused, and balanced. Although the performance of the three types of endorsement genres does not differ significantly, we find that the "person-then-project" pattern is superior to the "project-then-person" pattern in the balanced endorsement genre. In addition, we calculate endorsement sentiment, which is also an essential attribute of the endorsement genre, using a deep learning approach. The regression result suggests that a stronger endorsement sentiment induces a better campaign fundraising performance. In this line, we identify two endorsement genres: high- and low-sentiment endorsements. The campaigns with a high endorsement sentiment have better fundraising and participation performances than those with a low endorsement sentiment. We subsequently discuss the theoretical and practical implications and future research directions. [ABSTRACT FROM AUTHOR]

The escalating dissemination of health misinformation on social media platforms poses a significant threat to users' well-being. It is imperative to identify the types of health misinformation that are more susceptible to widespread dissemination and to explore strategies to curb its spread. This study designed a 2 (emotional appeal type: positive vs. negative) × 2 (fabricated source type: pseudo-common vs. pseudo-authoritative) × 2 (accuracy-nudge label: No vs. Yes) online between-subjects experiment controlling for factors such as e-health literacy, prior sharing experience, and personal involvement. A snowball sampling approach was used to recruit 1952 participants through social media, resulting in a final sample of 1393 valid responses. Compared to positive emotional appeal and pseudo-common sources, negative emotional appeal and pseudo-authoritative sources resulted in higher levels of sharing intention. Under the condition of negative emotional appeal, the promotion effect of pseudo-authoritative sources on sharing intention was intensified. The accuracy-nudge intervention could significantly mitigate this tendency. The underlying mechanisms revealed more details: both negative emotional appeals and pseudo-authoritative sources increased the perceived credibility of health misinformation, thereby increasing users' sharing intention. However, in contrast to pseudo-authoritative sources, excessive negative emotional appeal induced vigilant verification behavior among users, which reduced sharing to some extent. Adding an accuracy-nudge label to health misinformation reduced users' misguided trust in health misinformation features and stimulated information verification, ultimately reducing health misinformation sharing intention. Negative emotional appeal and pseudo-authoritative sources can enhance the perceived credibility of health misinformation, thereby strengthening the sharing intention of social media users. Therefore, health misinformation with negative emotional appeal and pseudo-authoritative sources is more likely to be widely shared. The accuracy nudge intervention can trigger users' information verification behavior, suppress the persuasive effects of the misinformation features mentioned above, and help prevent the spread of health misinformation on social media. • Health misinformation spreading on social media threatens users' well-being. • Negative emotional appeal and pseudo-authoritative sources lead to more mis-sharing. • Accuracy-nudge mitigated the effects of misinformation features on sharing intention. • Perceived credibility and information verification revealed underlying mechanisms.

The improvement of volunteer performance is a continuing issue in citizen science projects. From the perspective of motivational design, the provision of feedback is regarded as an effective design principle to promote user experience and performance in many contexts. We draw upon achievement goal theory and propose a research model to depict the influence of feedback types on perceived enjoyment, perceived meaning, and self-expansion, thereby further enhancing volunteer performance. We also investigate whether volunteers' dispositional goal orientation moderates the effects of feedback types on perceived enjoyment, perceived meaning, and self-expansion. A 3 (feedback types: task, self, and social feedback) × 2 (dispositional goal orientations: mastery- and performance-oriented) between-subject experiment was conducted to validate our research model. Results showed that task, self, and social feedback have varying impact on volunteers' experiences with citizen science projects. Individuals' dispositional goal orientation significantly interacted with feedback design in affecting volunteers' experiences. Moreover, the impact of feedback will be enhanced when feedback design is congruent with volunteers' dispositional goal orientation. Perceived enjoyment, perceived meaning, and self-expansion can positively influence volunteer performance, which is measured with the quantity and accuracy of their contributions. These findings will provide a groundwork for guidelines and strategies to enhance volunteer performance in citizen science projects. • Task, self, and social feedback affect volunteers' experiences differently in citizen science. • The effect of feedback is enhanced if feedback type is congruent with dispositional goal orientation. • Volunteers' experiences positively influence the quantity and accuracy of contributions.
