医患纠纷的网络报道-评论对受众对医信任倾向的影响与机制

研究通过2个实验,选取非医务工作者被试,考察网络媒体报道和在线评论对医患关系的影响机制。发现媒体报道方向、评论方向及评论内容的性质并不单独对受众的对医信任倾向产生显著影响。但三者的三重交互效应以及报道方向和评论内容性质的两重交互作用显著。具体而言,在正向报道条件下,尤其当评论方向为负向时,事实性的评论内容比情绪性的评论更能对受众的对医信任倾向产生消极影响。对于负向报道,阅读情绪性正向评论的被试比阅读情绪性中性评论的被试具有更高的对医信任倾向。研究结果发展了媒体传播理论和医患关系的社会舆论领域的研究,对于构建和谐医患关系具有实践指导意义。

叶紫文学评论述评

对叶紫的研究大体集中在两个方面,文本研究及作家研究。文章对叶紫的创作分为三个阶段,即雏生期,巩固期及挣扎期,并梳理归纳出每一分期作品的成功及其他评论家对叶紫作品优劣的所持观点。最后,从前人的研究成果中找到四个叶紫新论的切入口,旨在于重新发掘对其研究的意义和方向。

Evaluation of the propensity for coal spontaneous combustion based on catastrophe theory

Generally, different prevention measures should be taken according to spontaneous combustion propensities. The current methods to evaluate the propensity of coal spontaneous combustion, such as chromatographic method of oxygen adsorption, oxidation kinetics method and activation energy method, are mostly affected by human factors. Their boundaries among different classes of propensities were all established by subjective judgments. A new evaluation method using catastrophe theory is introduced. This method can accurately depict the process of coal spontaneous combustion and the evaluation index, ＂catastrophe temperature＂, be obtained based on the model. In terms of catastrophe temperature, the spontaneous combustion propensity of different coals can be sequenced. Experimental data indicate that this method is appropriate to describe the spontaneous combustion process and to evaluate the propensity of coal svontaneous combustion.
