危机事件中的网络视频传播与话语分析

随着网络视频的兴起,网络传播进入视频时代：对央视网和优酷网“甲型H1N1流感”议题的网络视频进行对比研究发现,在视频节目来源、话语平台的影响力和话语影响力以及话语呈现和对话机制方面,网络视频官方话语与民间话语的呈现都存在显著差异和一定规律。更为重要的是,网络视频传播在危机事件中的作用日益显著。     

Semiparametric inference of proportional odds model based on randomly truncated data

This paper studies the estimation in the proportional odds model based on randomly truncated data. The proposed estimators for the regression coefficients include a class of minimum distance estimators defined through weighted empirical odds function. We have investigated the asymptotic properties like the consistency and the limiting distribution of the proposed estimators under mild conditions. The finite sample properties were investigated through simulation study making comparison of some of the estimators in the class. We conclude with an illustration of our proposed method to a well-known AIDS data.     

关于俄罗斯灵魂的对话——高尔基与别尔嘉耶夫民族文化心理观的比较考察

俄罗斯作家高尔基和宗教哲学家别尔嘉耶夫都曾就俄罗斯民族灵魂的双重性、民族心理和民族命运的关系、集体主义和个性主义等问题分别进行过探讨,其观点和结论远不是一致的,但又具有某些联系和交叉,从而构成一种既彼此冲突、又互补互释的对话格局.考察他们各自的见解及其对话关系.对于深入认识20世纪前期俄罗斯文学精神与思想成果,有着显而易见的意叉.

Some new classes of multivariate survival distribution functions

The concept of the univariate mean remaining life (m.r.l.) function is generalized to the multivariate case. The multivariate mean remaining life (m.m.r.l.) function is utilized to introduce four new classes of multivariate survival distribution functions (s.d.f.'s). Each of these classes is a new generalization of the univariate decreasing mean remaining life (DMRL) class of s.d.f.'s. The duals of these classes are introduced. Some properties, physical interpretation, and relationships among these classes are investigated. Also for each case, the class of s.d.f.'s common in a class and its dual is characterized.     

植物抗病毒病基因工程研究与展望

用植物基因工程技术来获得抗病毒植物时研究主要通过以下五个途径:利用病毒外壳蛋白基因抑制病毒脱壳;利用mic免疫系统限制相应病毒复制;利用卫星RNA限制相关病毒的复制;利用ribozyme裂解病毒基因组;利用植物自身编码的抗病基因产物PR蛋白。本文对上述途径的近年研究作了综述和分析,并提出展望。
