Random effects regression mixtures for analyzing infant habituation

Random effects regression mixture models are a way to classify longitudinal data (or trajectories) having possibly varying lengths. The mixture structure of the traditional random effects regression mixture model arises through the distribution of the random regression coefficients, which is assumed to be a mixture of multivariate normals. An extension of this standard model is presented that accounts for various levels of heterogeneity among the trajectories, depending on their assumed error structure. A standard likelihood ratio test is presented for testing this error structure assumption. Full details of an expectation-conditional maximization algorithm for maximum likelihood estimation are also presented. This model is used to analyze data from an infant habituation experiment, where it is desirable to assess whether infants comprise different populations in terms of their habituation time.     

Media Disaster Reporting Effects on Public Risk Perception and Response to Escalating Tornado Warnings: A Natural Experiment

Previous research has evaluated public risk perception and response to a natural hazards in various settings; however, most of these studies were conducted either with a single scenario or after a natural disaster struck. To better understand the dynamic relationships among affect, risk perception, and behavioral intentions related to natural disasters, the current study implements a simulation scenario with escalating weather intensity, and includes a natural experiment allowing comparison of public response before and after a severe tornado event with extensive coverage by the national media. The current study also manipulated the display of warning information, and investigated whether the warning system display format influences public response. Results indicate that (1) affect, risk perception, and behavioral intention escalated as weather conditions deteriorated, (2) responses at previous stages predicted responses at subsequent stages of storm progression, and (3) negative affect predicted risk perception. Moreover, risk perception and behavioral intention were heightened after exposure to the media coverage of an actual tornado disaster. However, the display format manipulation did not influence behavioral responses. The current study provides insight regarding public perception of predisaster warnings and the influence of exposure to media coverage of an actual disaster event.

文章运用关联理论交际观,以汉语散文名篇中特有的形式量词短语及其英译为研究对象,介绍了汉语特有的形式量词短语,并根据关联理论交际观,从翻译是传递信息意图和交际意图双重目的的认知交际活动的角度来解析散文中形式量词短语及其英译技巧。试图证明关联理论交际观能够指导译者过滤汉语中有文化特异性的语言形式,从而顺利传达出原文作者的交际意图。     

论间接故意与过于自信的过失 --理论与实际的矛盾

间接故意与过于自信的过失是犯罪构成中主观方面最容易混淆的两种罪过,本文对这两种罪过进行了系统的比较,并对两者的实际操作中所体现的矛盾进行了分析,最后文章对矛盾提出了解决的方案。     

盗窃罪主观构成要件微探

盗窃罪主观构成要件的微观内涵在理论及实践中仍有若干问题存在争议。盗窃罪的主观构成要件包括犯罪故意和犯罪目的 ,盗窃罪故意中的认识因素包括对行为及对象的认识 ,盗窃罪的非法占有目的是一种超法规的主观要素 ,此犯罪目的是指永久性剥夺他人财物的心理态度。非法占有目的并非盗窃罪故意的内容而是超越故意的要素。行为时的具体认识错误对法律后果的评价至关重要 ,不同的错误类型对罪的认定的影响也不相同。     

一种新型的全光再生节点

提出了一种能够对采用副载波复用(SCM)标签技术的光分组信号进行再生的节点结构。该节点结构简单,不用进行波长变换,可以对SCM标签信号与负载信号分别进行全光再生。仿真结果表明再生节点可以保持SCM标签信号与负载信号频谱的稳定,不会产生串扰,再生效果良好。     

"绘画构图"浅说

绘画构图是绘画语言的要素之一,在绘画作品形成过程中,构图有着与线条、色彩等绘画语言同等重要的地位.本文从三个角度谈不同的绘画构图体现着画家不同的审美意向、追求、个性及给观者带来不同的视觉感受.     

论当前的物欲型犯罪

当前的物欲型犯罪有其经济根源和直接原因 ,其动机、行为方式及侵害对象具有一些带规律性的特点 ;犯罪人在市场经济中的地位 ,决定了其犯罪动机和行为方式。尤其少部分身居高位、掌握实权的领导干部或国有企业负责人对个人财富、权力的不当追求 ,导致权钱交易、化公为私 ,造成国有财产的大量流失。这种犯罪不断发生的重要原因是 ,国有财产所有者虚位 ;应从源头上遏制此类犯罪的蔓延
