浅论语境理论

旨在联系传统的静态语境和现代的动态语境分析 ,认为传统研究虽采用静态方法 ,出现描写能力过强的问题 ,但取得的成就不容忽视 ,而以顺应和认知理论为代表的动态语境观正是站在传统研究的基础上才形成系统的理论体系和完善语境的研究。     

一致性意识形态与当代中国制度变迁的动力学

当代中国的制度变迁是由政治家主导的,这一制度变迁的动力学在很大程度上可以用新的一致性意识形态来说明。事实上,如果没有新的一致性意识形态,中国的制度变迁是不可能取得成功的。

英汉语篇粘连手段差异及其对中国学生英文写作的影响

英汉语篇粘连手段存在着诸多的差异,本文从词汇手段、语法手段和结构手段三方面对英汉语篇粘连手段的异同进行分析,旨在找出造成中国学生英语写作欠连贯的原因,并指出在写作教学中可以尝试通过语言对比教学等来帮助学生提高英语写作水平。     

时空观演变对中晚唐诗风的影响

时空观是唐人个体觉醒的产物 ,也是诗风嬗变的关键。从中唐开始 ,时空观经历了一个从持续性、广延性向交替性、破碎性转变 ,从外张向内聚发展的过程。与之相适应 ,唐代的诗风也经历了多次变化。在与时空世界的矛盾中 ,唐人终于选择了承担 ,显示了刚健的生命力度 ,也赋予了诗歌巨大的张力

Multilevel models for longitudinal data

Summary.  Repeated measures and repeated events data have a hierarchical structure which can be analysed by using multilevel models. A growth curve model is an example of a multilevel random-coefficients model, whereas a discrete time event history model for recurrent events can be fitted as a multilevel logistic regression model. The paper describes extensions to the basic growth curve model to handle auto-correlated residuals, multiple-indicator latent variables and correlated growth processes, and event history models for correlated event processes. The multilevel approach to the analysis of repeated measures data is contrasted with structural equation modelling. The methods are illustrated in analyses of children's growth, changes in social and political attitudes, and the interrelationship between partnership transitions and childbearing.     

‘Wallbanking’, innovativeness and computer attitudes: 25–40-year-old ATM-users on the spot

Attitudes towards ‘wallbanking’ (making use of banking services through an Automated Teller Machine (ATM)) and self-reported frequency of wallbanking have been related to attitudes towards innovations and towards computers. The investigation also included the perception of advantages as well as disadvantages of wallbanking, factors that determine one's choice of a bank, man-machine problems related to the use of an ATM, and demographic factors. Using a sample of 201 respondents in the age range of 25 to 40 years, structural equation modeling revealed that wallbanking attitudes have a major influence on the frequency of using ATMs. The innovativeness attitude ‘New is wasteful’ also showed a clear negative link with the frequency of wallbanking. On the other hand, the relationship between computer attitudes and the frequency of using ATMs had to be rejected. Income and education proved to have an indirect link with the frequency of wallbanking, which refines other research findings. These results may reflect specific financial management characteristics of the age group under investigation.

Panel regression models for measuring multidimensional poverty dynamics

This work concerns the study of poverty dynamics and the analysis of the influencing socio-demographic factors. A fuzzy and multidimensional approach has been chosen in order to define two different poverty measures. A panel regression model has been estimated and particular attention has been paid to the treatment of the unobservable heterogeneity among longitudinal units. The specified model combines autoregression with variance components. The empirical analysis has been conducted using the data set of the British Household Panel Survey (BHPS) from 1991 to 1997. This work was co-financed by Murst funds for the projects “Occupazione e disoccupazione in Italia: misura e analisi dei comportamenti”. The paper is the result of the common work of all the authors; in particular G. Betti has written Sects. 2,5.1 and 5.3.1; A. D’Agostino has written sections 4, 5.2 and 5.4; L. Neri has written Sects. 1, 3, 5.3.2 and 6.
