君忌而臣危--论唐人小说中君臣关系的异化形态

作为君臣关系理想模式与良性状态的对立面,唐人小说又有相当的篇幅表现了君忌而臣危这种君臣关系的异化形态.这是道德层面的恶与人性劣根性的丑交叉作用的扭曲表现.唐代士人以小说的艺术形式,从前朝旧事、本朝新事和写实笔法、艺术虚构等多种角度表现之,寄寓了企盼"贞观之治"与"开元盛世"再现于当代的文化心理,蕴含着丰厚的思想内涵和超时空的认识价值.     

英汉双语对比阅读与跨文化交际能力的培养

阅读是外语学习的一种重要手段,它不仅是语言输入的主要来源,也是听、说、写、译等其它技能发展的基础。外语学习的最终目标是能使用该外语进行得体有效的跨文化交际。通过目标明确的英汉双语对比阅读,学习者能更有效地感知英语、汉语在语言和文化上的相通与不同,从而能有效提高他们的跨文化交际能力。     

Interval shrinkage estimators

This paper considers estimation of an unknown distribution parameter in situations where we believe that the parameter belongs to a finite interval. We propose for such situations an interval shrinkage approach which combines in a coherent way an unbiased conventional estimator and non-sample information about the range of plausible parameter values. The approach is based on an infeasible interval shrinkage estimator which uniformly dominates the underlying conventional estimator with respect to the mean square error criterion. This infeasible estimator allows us to obtain useful feasible counterparts. The properties of these feasible interval shrinkage estimators are illustrated both in a simulation study and in empirical examples.     

Likelihood inference for lognormal data with left truncation and right censoring with an illustration

The lognormal distribution is quite commonly used as a lifetime distribution. Data arising from life-testing and reliability studies are often left truncated and right censored. Here, the EM algorithm is used to estimate the parameters of the lognormal model based on left truncated and right censored data. The maximization step of the algorithm is carried out by two alternative methods, with one involving approximation using Taylor series expansion (leading to approximate maximum likelihood estimate) and the other based on the EM gradient algorithm (Lange, 1995). These two methods are compared based on Monte Carlo simulations. The Fisher scoring method for obtaining the maximum likelihood estimates shows a problem of convergence under this setup, except when the truncation percentage is small. The asymptotic variance-covariance matrix of the MLEs is derived by using the missing information principle (Louis, 1982), and then the asymptotic confidence intervals for scale and shape parameters are obtained and compared with corresponding bootstrap confidence intervals. Finally, some numerical examples are given to illustrate all the methods of inference developed here.     

Simultaneous confidence regions for the parameters of a Poisson INAR(1) model

The INAR(1) model (integer-valued autoregressive) is commonly used to model serially dependent processes of Poisson counts. We propose several asymptotic simultaneous confidence regions for the two parameters of a Poisson INAR(1) model, and investigate their performance and robustness for finite-length time series in a simulation study. Practical recommendations are derived, and the application of the confidence regions is illustrated by a real-data example.     

人力资本产权残缺:诠释浙江-陕西经济增长之谜

透过“浙江—陕西经济增长之谜”的研究发现,转型经济中的人力资本产权残缺已成为影响地区经济发展的重要因素;其残缺程度越大,则人力资本对经济发展的推动作用就越被弱化。     

别“愉”了孩子的未来——议循环经济发展中的文化意识因素

所有罪恶都来自“偷窃”,污染地球就是偷了孩子的未来。发展循环经济是实现可持续发展的最佳经济模式,在其发展中蕴含着中国传统文化中的“天人调谐”思想。实践中,通过官、产、民、学四方面把“天人调谐”思想转化为人们自觉的、能动的文化意识,构建与循环经济发展相适应的文化意识环境。     

财政支出行为对城乡基础设施差异影响的实证分析

文章认为,改革开放30年来,我国城乡基础设施的差异不断放大,这趋势主要源自地方政府间的财政支出竞争。在财力既定的条件下,为了吸引资本的流入,地方政府往往以绝对或相对减少农村基础设施投入为手段,保证城市基础设施建设对资金和劳动力的吸引,从而绝对或相对减少对农村基础设施建设的投入。

中英古诗中的爱情主题纵论

以爱情中的情感的发展历程为视角,通过对英国文艺复兴时期与中国古代文学中一描写爱情的诗歌对比分析,展现了一幅风格迥异又纵横交错的爱情世界的全景图.研究发现中英古诗中都包含大量讴歌爱情的激情诗句,但由于作者彼此情感经历的不同、中西文化差异等因素使二者在内容与形式的表述上各放异彩.
