Purpose The purpose of this paper is to construct an information ecology factor-TAM model to explore how information, people, and information environment impact mobile library users’ behavioral intention. Design/methodology/approach An empirical study based on an information ecology factor-TAM model. Findings The results of model test indicate that information, people, and information environment affect users’ behavioral intention to use mobile library in the information ecology environment. This paper provides a new theoretical perspective to understand users’ behavior of mobile library. It also provides practical guidelines to promote the usage of mobile library. Originality/value Internet of Things makes digital library one important channel for people to obtain information. Mobile internet makes it possible to access a variety of information anytime and anywhere. With the rapid grow of the number of mobile internet users, the usage of mobile library does not grow correspondingly. This paper explores the reasons.

Drawing upon social cognitive & social network theories, this study examines individual-level and network-level factors which potentially affect multicultural individuals’ information sharing behavior via social media. The data has been collected from the foreigners (multicultural individuals) who visited visa centers in three different cities in China. The proposed model tests a combined effect of past sharing experience (PE), trust (TR), perceived benefit (PB), perceived richness (RI), & information sharing attitude (ATT), on information sharing behavior (Beh). The data has been analyzed through Structural Equation Modeling (SEM). The results illustrate PE, TR and PB positively affects ATT which further influences Beh. Since scant studies focus on information sharing behavior of multicultural individuals – this research contributes to the IS literature, particularly to the information sharing via social media in a multicultural perspective. The results are likely to be useful guidance for practitioners and scholars intending to evaluate social media information sharing behavior.

PurposeBased on the examination of the roles of message framing and evidence type, this study made an analysis of the promotion methods of intention and information need towards HPV vaccination.Design/methodology/approachThe study conducted a 2 (gain-framed messages vs loss-framed messages) × 2 (statistical evidence vs narrative evidence) quasi-experimental design built upon theories of message framing and evidence type. This experiment recruited college students who were not vaccinated against HPV as participants. The analysis of variance (ANOVA), the analysis of covariance (ANCOVA), and the independent sample T-test were used to test the hypotheses.FindingsThe results (N = 300) indicate that (1) Loss-framed messages will lead to a more favorable intention towards HPV vaccination than gain-framed messages. (2) Statistical evidence will lead to a more explicit information need than narrative evidence. (3) Message framing and evidence type will interact and (a) for statistical evidence, loss-framed messages will lead to a more favorable intention towards HPV vaccination than gain-framed messages and (b) for narrative evidence, gain-framed messages will lead to a more favorable intention towards HPV vaccination than loss-framed messages. (4) Message framing and evidence type will interact and (a) for loss-framed messages, statistical evidence will stimulate more explicit information need of HPV vaccination than narrative evidence and (b) for gain-framed messages, narrative evidence will stimulate more explicit information need of HPV vaccination than statistical evidence.Originality/valueThis paper can help to further understand the important roles of message framing and evidence type in health behavior promotion. The study contributes to the literature on how health information can be well organized to serve the public health communication and further enhance the health information service.

Purpose The purpose of this study is to analyze the factors of the mobile library users’ attitude and behavioral intention from the perspective of information ecology. The research results could serve as a reference for the improvement of the mobile library services. Design/methodology/approach A model was constructed of the mobile library users’ attitude and behavioral intention with three external variables, namely, information quality, information environment and information technology, abstracted from the theory of information ecology. The influences of the three ecological factors were explored with empirical research and structural equation model. Findings Results showed that information quality, information environment and information technology had positive and significant effects on users’ attitude, among which the influence coefficient of information environment was the largest. Information technology and users’ attitude had positive and significant effects on the behavioral intention of users. This new theoretical perspective for research on the users’ mobile library behavior might have a positive role in promoting the development of mobile libraries. Practical implications This study suggests that the mobile library can improve the service mode in three aspects, namely, information quality, information environment and information technology to enhance the intention to use. Originality/value A theoretical model of the mobile library users’ behavioral intention is constructed from the perspective of information ecology. It can not only provide solid theoretical guidance for research on mobile libraries but also broaden the application of information ecology theory.
