廉洁文化传播是指一定的组织、个人通过特定的信息载体,运用一定的方式方法,向特定对象传播与廉洁有关的思想、观念、知识,从而使特定对象具备廉洁思想、意识和行为的社会活动。传播主体、传播内容、传播载体、传播方式是构成廉洁文化传播系统的四个要素,在传播过程中发挥着重要作用。从实践看,新媒体时代,廉洁文化传播普遍面临着多元主体的综合性知识需求与单一性知识现实之间的矛盾,完整性内容的系统性要求与碎片化表达之间的供需错配,多样载体的规范化管理与复杂治理之间的失衡、互动方式的生动性变革与刻板惯性之间的张力凸显等问题。因此,需要从以下几个方面提升新媒体时代廉洁文化传播实效性。一是提升廉洁文化传播主体的综合素养,着力从传播主体的思想观念、知识结构、能力素质等方面入手,打造一支适应新媒体时代需要的专业性廉洁文化传播队伍;二是加强廉洁文化内容的统筹设计,提升时代性和人民性;三是构建多元载体融合管理的体制机制,以构建全媒体传播体系为目标,加快传播载体格局的改革与重塑;四是提升廉洁文化传播方式的生动性与精准性,从讲述方式、呈现形式和传播手段三方面创新,结合移动端的传播特性,对廉洁文化内容进行精编和提炼,搭建形态丰富的新媒体内容矩阵,实现廉洁文化传播效率的全面提升。

Saline intrusion into sewage outfalls will greatly decrease the efficiency of the structures. The numerical model for this flow has been limited to one- and two-dimensional ones. In this article, a three-dimensional numerical model for saline intrusion and purging in sewage outfalls was developed. The flow was modeled in three dimensions under turbulent conditions with the RNG k-ε turbulence model. The numerical results provided quantitative evidence of the fundamental flow mechanisms that took place during saline intrusion and purging. The comparisons of the results with that of two-dimensional model and that of experiments indicate that the three-dimensional numerical model developed in this article is more effective in predicting the internal flow in outfalls.

This study uses the Elaboration Likelihood Model （ELM） and social presence theory to examine the microblogging reposting mechanism. Subjective and objective data were collected from 216 respondents in a field experiment. The results indicate that information quality and source credibility of microblogging messages affect users＇ reposting intention by affecting their perceptions of the usefulness and enjoyment of the information. Perceived enjoyment has a greater impact on reposting intention than perceived usefulness. Furthermore, users are able to perceive social presence when interacting with microblogging messages. Social presence plays a full mediating role between information quality and perceived enjoyment, and a partial mediating role between information quality and perceived usefulness.

In this paper, we discuss the a posteriori error estimate of the finite element approximation for the boundary control problems governed by the parabolic partial differential equations. Three different a posteriori error estimators are provided for the parabolic boundary control problems with the observations of the distributed state, the boundary state and the final state. It is proven that these estimators are reliable bounds of the finite element approximation errors, which can be used as the indicators of the mesh refinement in adaptive finite element methods.
