胡适文明观论析

本文比较系统地评述了胡适关于文明内涵的界定和中西近代民族文化意识的比较，进一步阐述胡适建立在比较、反省基础上的再造中国现代文明的思想，指出这是一种开放的、主动汇入世界现代文明潮流的有效途径。因此，胡适文明观在我国现代化发展中仍不失其意义。

从关联理论看语篇连贯

语篇连贯是语篇与非语篇的最大区别 ,韩礼德和哈桑把语篇的显性衔接看作是连贯的必要前提条件 ,本文对此作了批评 ,并以斯佩尔和威尔逊的关联理论为基点 ,集中讨论用关联认知方法构建连贯的语篇。     

Bayesian Experimental Design for Long-Term Longitudinal HIV Dynamic Studies

The study of HIV dynamics is one of the most important developments in recent AIDS research for understanding the pathogenesis of HIV-1 infection and antiviral treatment strategies. Currently a large number of AIDS clinical trials on HIV dynamics are in development worldwide. However, many design issues that arise from AIDS clinical trials have not been addressed. In this paper, we use a simulation-based approach to deal with design problems in Bayesian hierarchical nonlinear (mixed-effects) models. The underlying model characterizes the long-term viral dynamics with antiretroviral treatment where we directly incorporate drug susceptibility and exposure into a function of treatment efficacy. The Bayesian design method is investigated under the framework of hierarchical Bayesian (mixed-effects) models. We compare a finite number of feasible candidate designs numerically, which are currently used in AIDS clinical trials from different perspectives, and provide guidance on how a design might be chosen in practice.     

民族艺术展演空间的审美想像——湘西德夯苗寨的个案分析

民族艺术展演空间的建构是与民族艺术展演文本的生成紧密相联的,两者同时并进,互补互动。不同样式的展演文本需要不同形式的展演空间,同样,不同特质的展演空间适合不同审美风格的展演文本。受制于展演文本内容的复杂性特点,展演空间的建构因而也显得复杂。它是在对既有文化符号和形式进行陌生化结构重组的基础上,将原本作为自然村落的物理空间转换为置于"他者"视野中的文化世界,使得展演空间呈现为一个开放的、动态的和充满现代性追求意念的审美消费文化空间。     

城市发展中土地供应调控机制初探

一、我国城市土地供应机制的基本特点 1.以需定供,总量不限 我国大多数城市土地供应基本上采用"以需定供,总量不限"的方式,由于城市土地利用规划的滞后,土地管理的力度尚待加强,加上地方政府片面强调"以地生财"、"筑巢引凤",城市土地的供应往往缺乏时段性和空间性,在土地供应总量上也基本没有严格的限制.     

Goodness‐of‐fit methods for matched case‐control studies

The authors propose graphical and numerical methods for checking the adequacy of the logistic regression model for matched case‐control data. Their approach is based on the cumulative sum of residuals over the covariate or linear predictor. Under the assumed model, the cumulative residual process converges weakly to a centered Gaussian limit whose distribution can be approximated via computer simulation. The observed cumulative residual pattern can then be compared both visually and analytically to a certain number of simulated realizations of the approximate limiting process under the null hypothesis. The proposed techniques allow one to check the functional form of each covariate, the logistic link function as well as the overall model adequacy. The authors assess the performance of the proposed methods through simulation studies and illustrate them using data from a cardiovascular study.
