Due to the high perceived risk, building users’ initial trust is crucial to facilitating their adoption and usage of mobile banking. Drawing on the elaboration likelihood model (ELM), this research examined users’ initial trust in mobile banking. The results indicated that initial trust develops along a dual route including the central route and peripheral route. Self-efficacy as the elaboration likelihood moderates the effects of central cues and peripheral cues on initial trust. Central cues include information quality and service quality, whereas peripheral cues include system quality, structural assurance and reputation. The results imply that service providers need to employ differentiated strategies to build users’ initial trust in mobile banking.
Purpose - The purpose of this study is to examine the determinants of online community user participation from a social influence perspective.Design methodology approach - Based on 450 valid ...responses collected from a survey questionnaire, structural equation modeling (SEM) technology was employed to examine the research model.Findings - The results show that both social identity and group norm have significant effects on user participation. In addition, group norm affects social identity. It was not possible to find the effect of subjective norm on participation intention.Research limitations implications - This research is limited to a particular sample: students. Thus the results need to be generalized to other samples, such as working professionals.Originality value - Extant research has mainly focused on the effects of user motivations such as perceived usefulness, trust and commitment on online community user behavior, and seldom considered the effects of social processes including compliance, identification and internalization on user behavior. This research tries to fill the gap.
Link prediction is a paradigmatic problem in network science, which aims at estimating the existence likelihoods of nonobserved links, based on known topology. After a brief introduction of the ...standard problem and evaluation metrics of link prediction, this review will summarize representative progresses about local similarity indices, link predictability, network embedding, matrix completion, ensemble learning, and some others, mainly extracted from related publications in the last decade. Finally, this review will outline some long-standing challenges for future studies.

Classical wind energy conversion systems are usually passive generators. The generated power does not depend on the grid requirement but entirely on the fluctuant wind condition. A dc-coupled ...wind/hydrogen/supercapacitor hybrid power system is studied in this paper. The purpose of the control system is to coordinate these different sources, particularly their power exchange, in order to make controllable the generated power. As a result, an active wind generator can be built to provide some ancillary services to the grid. The control system should be adapted to integrate the power management strategies. Two power management strategies are presented and compared experimentally. We found that the "source-following" strategy has better performances on the grid power regulation than the "grid-following" strategy.
Due to the high uncertainty and perceived risk associated with using mobile payment, it is critical to building users’ initial trust in order to facilitate their adoption and usage. Drawing on both ...perspectives of self-perception-based and transference-based factors, this research examined initial trust in mobile payment. Self-perception-based factors include ubiquitous connection and effort expectancy, whereas transference-based factors include structural assurance and trust in online payment. The results indicated that both perspectives of factors affect initial trust, which further affects performance expectancy and usage intention. Thus, service providers need to build users’ initial trust in order to facilitate their usage of mobile payment.

•Phosphoric acid was innovatively used as leaching and precipitating ...agent.•Over 99% Co and Li can be separated and recovered in a single leaching step.•Co and Li can be separated under mild conditions of 40°C and 0.7M H3PO4.•Activation energy values for Co and Li are 7.3 and 10.168kJ/mol.•Cobalt phosphate (97.1% in purity) can be obtained as the leaching product.
Sustainable recycling of valuable metals from spent lithium-ion batteries (LIBs) may be necessary to alleviate the depletion of strategic metal resources and potential risk of environmental pollution. Herein a hydrometallurgical process was proposed to explore the possibility for the recovery of valuable metals from the cathode materials (LiCoO2) of spent LIBs using phosphoric acid as both leaching and precipitating agent under mild leaching conditions. According to the leaching results, over 99% Co can be separated and recovered as Co3(PO4)2 in a short-cut process involved merely with leaching and filtrating, under the optimized leaching conditions of 40°C (T), 60min (t), 4 vol.% H2O2, 20mLg−1 (L/S) and 0.7mol/L H3PO4. Then leaching kinetics was investigated based on the logarithmic rate kinetics model and the obtained results indicate that the leaching of Co and Li fits well with this model and the activation energies (Ea) for Co and Li are 7.3 and 10.2kJ/mol, respectively. Finally, it can be discovered from characterization results that the obtained product is 97.1% pure cobalt phosphate (Co3(PO4)2).
Extant research has focused on the initial adoption and usage of mobile services and paid little attention to the post-adoption and continuance usage. However, unless users continue using mobile ...services, service providers cannot achieve success. Drawing upon the expectation confirmation theory, this research develops a mobile post-adoption model. The post-adoption behaviour includes three variables: continuance intention, recommendation and complaint. We conducted data analysis with partial least squares. The results indicated that expectation confirmation, perceived ease of use, perceived usefulness and usage cost significantly affect users' satisfaction, further determining their post-adoption behaviour. In addition, perceived usefulness has a direct effect on the continuance intention.
