社会影响力——传播学的新视角

社会影响力是指运用个人或团体的社会力量和法制手段在特定方向上改变他人态度或行为,也指一定历史或自然改变后人或社会的状况.在运行方式上,社会影响力主要有上下垂直影响、横向平行影响和复合型影响三种类型.在主体内容上,社会影响力可以分为文化影响力、政治影响力、宗教影响力、人物影响力和事件影响力等.作为一种动态的行为过程,社会影响力具有惯性运动、社会需求、文体认同、互动强化以及力源决定等特征.     

马克思的实践哲学与现代性批判

理性主义观念、主体性原则以及文化分化的表征不仅构成了现代性的主要方面,而且也成为现代性危机的主要原因.因此,我们需要一种新的哲学观念来反思现代性的发展,并在此基础上重新构建人与世界、人与人的关系.而马克思的实践哲学中蕴含的对实践概念和实践活动的理解则成为反思和批判现代性的重要视角.

政府资金来源在农村社会保障建设中的主导地位及立法建议

资金来源是否有保障,是农村社会保障建设成败的关键。政府为农村社会保障提供资金支持,是公共财政的职能体现。从现实来看,政府作为最重要的大责任主体其投入不足。之所以会出现这种状况,主要有两大原因：一是对农村社会保障认识存在误区;二是农村社会保障资金来源的法律阙如。政府主导的资金来源及立法,可着重考虑以下方面：在《预算法》等法律中增加财政支持农保的相关规定;在《土地管理法》中明确政府可从土地收益中提取农保资金;将投向“三农”的资金纳入《农民权益保护法》转化为农保资金;适时制定《社会保障税法》开征社会保障税;立法规范国有股转持充实社保资金账户。     

Easy-to-construct confidence bands for comparing two simple linear regression lines

This paper shows how to construct confidence bands for the difference between two simple linear regression lines. These confidence bands provide directly the information on the magnitude of the difference between the regression lines over an interval of interest and, as a by-product, can be used as a formal test of the difference between the two regression lines. Various different shapes of confidence bands are illustrated, and particular attention is paid towards confidence bands whose construction only involves critical points from standard distributions so that they are consequently easy to construct.     

具有GARCH（1，1）-正态误差项的非对称单位根检验研究

摘　　要:理论研究表明许多经济变量呈现出非对称的门限自回归（TAR）或动态门限自回归（M-TAR）数据生成机制,因而非对称单位根检验就成为该领域的主要研究方向之一。本文对非对称单位根检验Enders-Granger方法在GARCH（1,1）-正态误差项下的检验水平与检验势作了系统的仿真研究。研究表明：GARCH（1,1）-正态误差项的TAR或M-TAR模型会对该方法的检验水平和检验势产生重要影响。

PES-C,(PP/Bis-T)PES的次级松驰与转变

描述了酚酞型聚芳醚砜(PES-C)的次级松驰和转变与其结构的关系.TBA和动态力学实验结果表明:PES-C及其共聚物(PP/Bis-T)PES分别在0～50℃和-100℃附近呈现出两个次级松驰峰;双酚T单元的引入导致了PES-C在0～50℃之间的次级松驰位置改变.证实了Cardo侧基的存在对-100℃的次级松驰有较大的贡献.     

Influence of human immunodeficiency virus infection on neurological impairment: an analysis of longitudinal binary data with informative drop-out

A study to investigate the human immunodeficiency virus (HIV) status on the course of neurological impairment, conducted by the HIV Center at Columbia University, followed a cohort of HIV positive and negative gay men for 5 years and assessed the presence or absence of neurological impairment every 6 months. Almost half of the subjects dropped out before the end of the study for reasons that might have been related to the missing neurological data. We propose likelihood-based methods for analysing such binary longitudinal data under informative and non-informative drop-out. A transition model is assumed for the binary response, and several models for the drop-out processes are considered which are functions of the response variable (neurological impairment). The likelihood ratio test is used to compare models with informative and non-informative drop-out mechanisms. Using simulations, we investigate the percentage bias and mean-squared error (MSE) of the parameter estimates in the transition model under various assumptions for the drop-out. We find evidence for informative drop-out in the study, and we illustrate that the bias and MSE for the parameters of the transition model are not directly related to the observed drop-out or missing data rates. The effect of HIV status on the neurological impairment is found to be statistically significant under each of the models considered for the drop-out, although the regression coefficient may be biased in certain cases. The presence and relative magnitude of the bias depend on factors such as the probability of drop-out conditional on the presence of neurological impairment and the prevalence of neurological impairment in the population under study.
