Roles of community commitment and community atmosphere: an empirical study of online community success

Online communities have become quite popular, and both practitioners and researchers have focused on the determinants of and the evaluation of online community success. The success of online community is not only embodied in the usage but also on the members’ intention to stick with the community over time. Based on the updated DeLone and McLean’s IS Success Model, and incorporating the theory of organization commitment, we propose a research model to investigate the key factors that lead to online community success. In our model, we depict the roles of community commitment and community atmosphere. On the basis of the existed scales, we develop an instrument and design a questionnaire. We conduct a survey and collect 273 answered responses in Xi’an. We use AMOS7.0 to make an analysis of the collected data. Our result indicates that continuance and affective community commitment have prominent influences on members’ usage behavior; but system quality, information quality, and community atmosphere do not affect the three components of community commitment simultaneously. System quality and information quality help to increase members’ continuance community commitment, and information quality and community atmosphere have a significant effect on affective commitment. This study may enrich the understanding of online community success by considering the roles of community commitment and their relationship with members’ usage

The primitive equations with magnetic field approximation of the 3D MHD equations

In our earlier work \cite{DLL}, we have shown the global well-posedness of strong solutions to the three-dimensional primitive equations with the magnetic field (PEM) on a thin domain. The heart of this paper is to provide a rigorous justification of the derivation of the PEM as the small aspect ratio limit of the incompressible three-dimensional scaled magnetohydrodynamics (SMHD) equations in the anisotropic horizontal viscosity and magnetic field regime. For the case of $H^1$-initial data case, we prove that global Leray-Hopf weak solutions of the three-dimensional SMHD equation strongly converge to the global strong solutions of the PEM. In the $H^2$-initial data case, the strong solution of the SMHD can be extended to be a global one for small \v. As a consequence, we observe that the global strong solutions of the SMHD strong converge to the global strong solutions of the PEM. As a byproduct, the convergence rate is of the same order as the aspect ratio parameter.Comment: arXiv admin note: text overlap with arXiv:2206.06005; text overlap with arXiv:1706.08885 by other author

Rewriting, Ideology, and Poetics in Goldblatt\u27s Translation of Mo Yan\u27s 天堂蒜薹之歌 (The Garlic Ballads)

In their article Rewriting, Ideology, and Poetics in Goldblatt\u27s Translation of Mo Yan\u27s 天堂蒜薹之歌 (The Garlic Ballads) Ping Du and Lili Zhang analyze Howard Goldblatt\u27s translation of the novel in order to explore literary rewriting in translation. Du and Zhang posit that Goldblatt\u27s translation reflects ideology in concealing, discarding, rewriting, and even losing some part in his translation. Further, they argue that the translation of the novel has beenperformed based on specific aspects of poetics including the musical charm of Chinese ballads and their unique cultural images
