论政治文明的文化选择

文化即人化,它是人类所创造的精神成果和物质成果的总和;文明是文化的结晶,是文化主体对人类文化中野蛮性、愚昧性不断扬弃的结果,是人类有目的、有选择地过滤人类文化、形成合理文化内核的过程。中国当前的政治文明建设,需要走出“精华”和“糟粕”的简单二分的误区,用外来文化中国化、传统文化现代化,来开辟中国文化发展之路。弱化暴力色彩,强化仁政效应,构建中国特色的政治文明。     

高等学校实施双语教学的思考

随着经济和教育全球一体化的进程加快,高等学校的双语教学将占有越来越大的比重,双语教学对推动学校的发展和建设的作用日益明显。故研究从双语教学的必要性、影响双语教学的因素和香港四所大学授课语言环境所感等三个方面进行探讨,并对如何有效进行双语教学进行了分析,以期为高等学校双语教学的开展及实施提供理论和实践依据。     

鲁迅与波德莱尔的话语共鸣

《野草》和《巴黎的忧郁》是鲁迅和波德莱尔的散文诗集,两位伟大的作家选择了相同的文体,运用象征手法,选择特有的意象,表达时代的抑郁和苦闷。由此形成了两者的话语共鸣,体味出新的审美典范。散文诗以其特殊的话语形态表达作者的心理情感及其想像空间,鲁迅与波德莱尔一方面具备写作散文诗的特质,另一方面时代也促成了他们选择这样的话语形态,由此透过两位大作家的文字,我们体味到两者文本之中的话语共鸣——精神的忧郁、心灵的苦闷;同时也体味到世界文学的共鸣。

招贴设计的方法论研究

招贴设计的方法论研究是平面设计基础理论的一个重要支系,由于招贴设计自身的复杂性,与之对应的方法论研究不应等同于一般的设计方法论.文章突破了旧有的研究体系,尝试从哲学、图像学、潜意识等多个角度去剖析创意生成的奥秘,进而引导初学者完成创意的构思.     

网络集群的自组织特征 —— 以“南京梧桐树事件”的微博维权为个案

近年来,伴随着急剧的社会结构转型,我国新的社会身份和社会认同群体也随之产生,在网络中的政治表达和利益维护活动增多,在这些网络讨论的集群内部,参与者会自发形成一定的秩序,推动事件的进行。本研究利用自组织理论作为分析框架,选取"南京梧桐树事件"的微博维权集群为研究对象,重点考察网络集群参与者之间从无序到有序的互动过程、整个系统的演变规律及其与外界的互动机制,由此总结出网络集群中的自组织特征,从而相对准确地把握虚拟社区系统的发展、演化阶段,为更好地理解互联网的社会功能起到借鉴作用,也为政府有关部门做好群体事件的预防工作提供理论和策略上的支持。     

Bayesian nonparametric modelling of the link function in the single-index model using a Bernstein–Dirichlet process prior

This paper proposes the use of the Bernstein–Dirichlet process prior for a new nonparametric approach to estimating the link function in the single-index model (SIM). The Bernstein–Dirichlet process prior has so far mainly been used for nonparametric density estimation. Here we modify this approach to allow for an approximation of the unknown link function. Instead of the usual Gaussian distribution, the error term is assumed to be asymmetric Laplace distributed which increases the flexibility and robustness of the SIM. To automatically identify truly active predictors, spike-and-slab priors are used for Bayesian variable selection. Posterior computations are performed via a Metropolis-Hastings-within-Gibbs sampler using a truncation-based algorithm for stick-breaking priors. We compare the efficiency of the proposed approach with well-established techniques in an extensive simulation study and illustrate its practical performance by an application to nonparametric modelling of the power consumption in a sewage treatment plant.     

A misspecification test for the higher order co-moments of the factor model

The traditional estimation of higher order co-moments of non-normal random variables by the sample analog of the expectation faces a curse of dimensionality, as the number of parameters increases steeply when the dimension increases. Imposing a factor structure on the process solves this problem; however, it leads to the challenging task of selecting an appropriate factor model. This paper contributes by proposing a test that exploits the following feature: when the factor model is correctly specified, the higher order co-moments of the unexplained return variation are sparse. It recommends a general to specific approach for selecting the factor model by choosing the most parsimonious specification for which the sparsity assumption is satisfied. This approach uses a Wald or Gumbel test statistic for testing the joint statistical significance of the co-moments that are zero when the factor model is correctly specified. The asymptotic distribution of the test is derived. An extensive simulation study confirms the good finite sample properties of the approach. This paper illustrates the practical usefulness of factor selection on daily returns of random subsets of S&P 100 constituents.     

Lower bound of average centered L2-discrepancy for U-type designs

Uniform designs are widely used in various scientific investigations and industrial applications. By considering all possible level permutation of the factors, a connection between average centered L₂-discrepancy and generalized wordlength pattern for asymmetrical fractional factorial designs is derived. Moreover, we present new lower bounds to the average centered L₂-discrepancy for symmetrical and asymmetrical U-type designs. For illustration of the theoretical results, the lower bounds for symmetrical and asymmetrical U-type designs are tabulated, and numerical results indicate that our lower bounds behave well and can be recommended for use in practice.     

The laws of large numbers for Pareto-type random variables with infinite means

In this paper, we consider the laws of large numbers for NSD random variables satisfying Pareto-type distributions with infinite means. Based on the Pareto-Zipf distributions, some weak laws of large numbers for weighted sums of NSD random variables are obtained. Meanwhile, we show that a weak law for Pareto-Zipf distributions cannot be extended to a strong law. Furthermore, based on the two tailed Pareto distribution, a strong law of large numbers for weighed NSD random variables is presented. Our results extend the corresponding earlier ones.
