四级写作低分段评分样本的功能分析

为了客观、系统地研究大学英语四级低分段写作的基本语法和文体特点 ,有必要从系统功能语法的角度对评分样本进行统计分析。系统功能语法比传统语法具有诸多的优越性 ,能够全面细致地对语言现象进行分析。对评分样本的分析 ,有助于客观地研究克服经验主义倾向     

商业银行董事会治理的独立有效性研究

根据经济合作与发展组织、巴塞尔银行监管委员会和中国银行业监督管理委员会等组织关于公司治理的相关原则、指引和法律规定,对商业银行董事会的独立有效性进行了综合分析,得出商业银行董事会的独立有效性主要体现在独立董事的独立性,职能委员会的独立性以及独立董事占董事会成员的比例3个方面以及规范的独立董事、职能委员会的产生机制和明确的独立董事、职能委员会的责权利制度是确保商业银行董事会独立有效性基础的结论,并提出中国商业银行董事会的适度规模为11人,其中独立董事占董事会成员的合适比例为50％以上的建议。     

大吴文化研究纵横谈

大吴文化是一种广义的地域文化 ,即从古到今 ,吴地人民所创造的一切文化的总汇。吴地地域的界定 ,有广义、狭义之分 ,广义的吴地地域的界定应以历史政区和吴语分布区为依据。从大吴文化视角出发 ,可将吴文化视为一种丰富的知识性的资源 ,人们可纵横结合 ,从人类社会的多个层面予以研究、开发和利用。在长期的发展中 ,吴文化形成了先吴文化、吴国文化、吴地文化三个时期。吴文化具有自己的鲜明特色 ,其中主要有依托水 ;融合古今 ,汇通中西 ;后来居上 ,敢为天下先等     

界定语言的逻辑理路

迄今,还没有一门科学像语言学这样不能提供研究对象的结论性定义。语言有三个本质属性,即社会事实、心理表征及声音和意义结合的符号系统,只有对语言进行三维观照,才有可能本真地推导出语言这一语言学对象所特有的、本质的属性     

Backfitting Random Varying-Coefficient Models with Time-Dependent Smoothing Covariates

Abstract.  In this paper, we propose a random varying-coefficient model for longitudinal data. This model is different from the standard varying-coefficient model in the sense that the time-varying coefficients are assumed to be subject-specific, and can be considered as realizations of stochastic processes. This modelling strategy allows us to employ powerful mixed-effects modelling techniques to efficiently incorporate the within-subject and between-subject variations in the estimators of time-varying coefficients. Thus, the subject-specific feature of longitudinal data is effectively considered in the proposed model. A backfitting algorithm is proposed to estimate the coefficient functions. Simulation studies show that the proposed estimation methods are more efficient in finite-sample performance compared with the standard local least squares method. An application to an AIDS clinical study is presented to illustrate the proposed methodologies.     

LENGTH-BIASING, CHARACTERIZATIONS OF LAWS AND THE MOMENT PROBLEM

A positive random variable X with a finite mean has an induced length-biased law represented by Y, and Y is stochastically larger than X. An independent uniform random contraction of Y, UY, has the same law as X if and only if the latter is exponential. This property is extended to non-uniform contractions and a more general notion of length-biasing. The distributional equality of X and W leads to a functional equation for the moment function of X, which has either Infinitely many solutions or none. When U is constant, X can have a log-normal law, but it can also have laws with the same moment sequence as this log-nod law. The case where U has a certain beta, or generalized beta, law give t3 characterizations of generalized gamma laws, or to products of independent copies of them. This occurs even when these laws are not determined by their moment sequences.     

Defining child abuse in Hong Kong

Definitions of child abuse are culturally driven. Hong Kong, with a predominantly Chinese population, has managed to eradicate much of the societal abuse that children suffer elsewhere in Asia. Professional and government attention has now shifted to child abuse and neglect within the family. The paper, based on interviews with key professionals. analysis of policy documents and practice records examines traditional Chinese parent-child relationships. the status of parental authority and corporal punishment and changes in contemporary Hong Kong family life. It goes on to outline the development of responses to child abuse in Hong Kong, some of the dilemmas that professionals face in defining abuse and areas for future research.     

犯罪本质与本质特征新界说

由于没有先弄清犯罪本质与犯罪本质特征的关系,故国内刑法学至今还在回避犯罪本质问题,对犯罪本质特征也没有提出令人信服的看法。从哲学的角度来看,犯罪本质是犯罪的内在规定性,决定着犯罪本质特征,而犯罪本质特征则是犯罪本质的外在体现;立于犯罪构成的内在联系及其结构和刑罚的目的与功能,犯罪本质应是犯罪人之于社会秩序的极端蔑视态度,而立于犯罪与一般违法行为的区别,犯罪本质特征应是应受刑罚惩罚性。     

原生态文化的界定及其保护

原生态文化的学术界定历来存在极大纷争,原生态文化虽在概念的界定上有不严格之处,但从实践的角度看,有其存在的合理性,由此提出原生态文化的大概念观点。只有尽快确立原生态文化著作权的立法,通过引进民间资本、借助现代媒体等手段,建立健全原生态文化保护机制,才能达到对原生态文化既保护又开发的目的。     

音系层、词汇语法层与语义层三位一体的英语教学

韩礼德的系统功能语法直接和间接地激发了许多新的教学理论和方法的产生。英语教学中应尝试把该语法的六个核心思想之一的“层次的思想”与英语词汇教学联系起来,通过音系层、词汇语法层和语义层三位一体的英语教学法提高学生的英语综合知识和技能。
