Attention and Executive Functions as Mediators of Attachment and Behavior Problems

The purpose of this study was to provide a more comprehensive understanding of the relation between early parent‐child interactions and subsequent behavior problems and how certain cognitive processes mediate this relation. Specifically, this study investigated whether attention, inhibition, and planning skills mediate the relation between attachment security and behavior problems. Data were collected as part of the National Institute of Child Health and Development‐Study of Early Child Care and Youth Development when children (N = 1004) were between 36 months and the third grade. Results from structural equation models indicated that sustained attention mediated the relation between disorganized attachment and social problems. Planning mediated the relation between disorganized attachment and subsequent thought problems, attention problems, and delinquent behavior. Avoidant, ambivalent, and disorganized attachment directly predicted several behavior problems. Implications for theory and future research are discussed.     

A procedure for testing the equality of k dependent correlation coefficients

A procedure is proposed for testing the equality of k dependent correlation coefficients. The procedure is simulated utilizing Monte Carlo techniques; and, a method for post hoc probing is also suggested.     

基于长沙市T区社区管理模式现状的思考

以长沙市T区为分析案例,通过对T区进行调查研究,寻找当前长沙市社区管理模式存在的一些问题:管理体制的行政化,政府职能的错位与缺位,居民与社区中介组织参与社区管理程度低,社区工作任务繁重,等等。要解决当前社区管理存在的一系列问题,必须重新考析政府、社区、社区中介组织以及居民之间的关系,理顺社区管理体制,明确政府职能,大力培育社区中介组织,培养居民的参与意识,构建长沙市功能型社区管理模式。     

社会修辞学视域下的巴赫金对话理论研究

社会修辞学是当代西方修辞学的主流理论形态,该理论研究的基本命题是修辞参与社会构建,人们通过话语修辞活动传递信息、参与社会事务并进行社会实践与合作。巴赫金对话主义理论中有关话语的对话性、语境论以及话语意识形态的哲学思想蕴含着深厚的社会修辞学思想,在本体论以及认识论上给西方传统修辞学带来了理论给养,推动了当代西方社会修辞学研究范式的确立。基于此,从话语构建与阐释维度探讨了巴赫金对话理论所蕴含的社会修辞观,进而明晰社会修辞学的理论本质与内涵。     

基于伯克认同理论的品牌命名研究

Variable selection in elliptical linear mixed model

Variable selection in elliptical Linear Mixed Models (LMMs) with a shrinkage penalty function (SPF) is the main scope of this study. SPFs are applied for parameter estimation and variable selection simultaneously. The smoothly clipped absolute deviation penalty (SCAD) is one of the SPFs and it is adapted into the elliptical LMM in this study. The proposed idea is highly applicable to a variety of models which are set up with different distributions such as normal, student-t, Pearson VII, power exponential and so on. Simulation studies and real data example with one of the elliptical distributions show that if the variable selection is also a concern, it is worthwhile to carry on the variable selection and the parameter estimation simultaneously in the elliptical LMM.     

论清代海外华文报刊的社会功能及特点

清代的海外华文报刊是中国新闻事业的重要组成部分,也是海外华人华侨精神生活不可或缺的组成部分.在我国1000多年的新闻传播史中,清代海外华文报刊处于中国报刊走向近代化的初期和创始阶段,这些华文报刊在宣传爱国思想、弘扬传统文化、传播科技知识、引导政治导向,以及反映华侨华人的爱国之情和沟通与祖国的联系方面,发挥了重要的传媒功能.清代的海外华文报刊呈现出报刊生存时间普遍较短、处于当地主流文化之外、政治倾向性由弱到强的传播特点,但海外华文报刊的出现和发展也反映了华侨华人社会地位的提高.     

浅论诗歌语言的隐喻特质

中国古代美学提倡含蓄朦胧、蕴籍风流,诗歌作为最能体现古典美学精神的文学样式,利用语词的隐喻特质,极大地拓宽了诗歌的审美空间,丰富了诗歌的审美内涵。主要探讨诗歌与语词的隐喻关联,同时简要归列了解析语词隐喻内涵的方法,力求从隐喻阐释理论的高度对诗歌的多义主题及丰富寓意作出更合理的解释和还原。     

GMM Estimation with persistent panel data: an application to production functions

This paper considers the estimation of Cobb-Douglas production functions using panel data covering a large sample of companies observed for a small number of time periods. GMM estimatorshave been found to produce large finite-sample biases when using the standard first-differenced estimator. These biases can be dramatically reduced by exploiting reasonable stationarity restrictions on the initial conditions process. Using data for a panel of R&Dperforming US manufacturing companies we find that the additional instruments used in our extended GMM estimator yield much more reasonable parameter estimates.
