论传统文化与现代化

现代化是一种历史的必然,中国传统文化必须根据现代化的要求进行改造。首先,中国文化中与封建社会相联系的部分必须抛弃;其次,中国传统文化中关于人、人性、做人的基本精神和基本原则。要根据现代化的发展进行新的诠释;再次,必须吸收西方文化中的合理成分。只有经过这样的改造,中国传统文化才能适应现代化的发展。     

关于移就的定义

以往移就的定义都脱不了传统范畴观的窠臼,往往采用单一标准界定这一范畴边缘模糊的综合性修辞手段。典型范畴理论能很好地解决这一问题。移就是将通常用于修饰、描写甲事物性状的词语移用到乙事物上去,典型的转移方式是移人类性状于外物,典型的句法形式是形名组合的定中结构。     

全球化对海外华文教育的影响

全球化将波及到人类生活的各层面,也对海外华人产生多方面的影响。随着华人活动的全球化,带动华语言文化的广泛传播,海外华文教育随之而发生演变。全球化时代必将带来华人的文化整合,华人必须在参与世界现代化、全球化的过程中,与各自国家的发展寻求平衡;同时保持民族性,使自身文化的特质进一步明确与突显。全球化也必将带来华文教育的整合。全球化将把海外华文教育带人一个新时代。     

Construction of bivariate and multivariate weighted distributions via conditioning

Weighted distributions (univariate and bivariate) have received widespread attention over the last two decades because of their flexibility for analyzing skewed data. In this article, we propose an alternative method to construct a new family of bivariate and multivariate weighted distributions. For illustrative purposes, some examples of the proposed method are presented. Several structural properties of the bivariate weighted distributions including marginal distributions together with distributions of the minimum and maximum, evaluation of the reliability parameter, and verification of total positivity of order two are also presented. In addition, we provide some multivariate extensions of the proposed models. A real-life data set is used to show the applicability of these bivariate weighted distributions.     

Pricing power options with a generalized jump diffusion

In this article, the valuation of power option is investigated when the dynamic of the stock price is governed by a generalized jump-diffusion Markov-modulated model. The systematic risk is characterized by the diffusion part, and the non systematic risk is characterized by the pure jump process. The jumps are described by a generalized renewal process with generalized jump amplitude. By introducing NASDAQ Index Model, their risk premium is identified respectively. A risk-neutral measure is identified by employing Esscher transform with two families of parameters, which represent the two parts risk premium. In this article, the non systematic risk premium is considered, based on which the price of power option is studied under the generalized jump-diffusion Markov-modulated model. In the case of a special renewal process with log double exponential jump amplitude, the accurate expressions for the Esscher parameters and the pricing formula are provided. By numerical simulation, the influence of the non systematic risk’s price and the index of the power options on the price of the option is depicted.     

在世俗之上:“信仰中国”的认知与实践价值

李向平认为,从辛亥革命开始的现代中国"革命"运动对当代中国的"信仰"变迁及其重建产生了重要而深远的影响,源自于民国初年以"三民主义"为核心的"主义信仰"及其建构渐次成为"主义建构信仰"乃至"主义代替宗教"的政治思潮,深刻制约着现代中国"信仰"的建构与演变趋势。傅有德认为,与西方的信教主体不同,中国的宗教性信仰主体存在着较为普遍的"一人多信"现象,这既与宗教信仰间的兼容甚至合流有关,也与信仰而不必委身的理念有关,还与缺乏终极的精神关怀有关,更与中国人思维方式中"求同存异"的特点有关。任剑涛认为,中国迈上小康之路的这一变化,将四维中国的形象完整地刻画出来:"经济中国"构成中国的基础性物化维度,"政治中国"构成中国的国家—法律物化维度,"文化中国"构成中国的物质生活与精神生活的交叠维度,"信仰中国"构成中国的深刻价值支持维度;四个维度相互支撑,构成完整的、现代的"中国"。     

Comparing mean ranks for repeated measures data

Rank tests are considered that compare t treatments in repeated measures designs. A statistic is given that contains as special cases several that have been proposed for this problem, including one that corresponds to the randomized block ANOVA statistic applied to the rank transformed data. Another statistic is proposed, having a null distribution holding under more general conditions, that is the rank transform of the Hotelling statistic for repeated measures. A statistic of this type is also given for data that are ordered categorical rather than fully rankedo Unlike the Friedman statistic, the statistics discussed in this article utilize a single ranking of the entire sample. Power calculations for an underlying normal distribution indicate that the rank transformed ANOVA test can be substantially more powerful than the Friedman test.     

First-exit times for compound poisson processes for some types of positive and negative jumps

We consider the one-sided and the two-sided first-exit problem for a compound Poisson process with linear deterministic decrease between positive and negative jumps. This process (X(t)) _t≥0 occurs as the workload process of a single-server queueing system with random workload removal, which we denote by M/G _u /G _d /1, where G _u (G _d ) stands for the distribution of the upward (downward) jumps; other applications are to cash management, dams, and several related fields. Under various conditions on G _u and G _d (assuming e.g. that one of them is hyperexponential, Erlang or Coxian), we derive the joint distribution of τ _y =inf{t≥0|X(t)?(0,y)}, y>0, and X(τ _y ) as well as that of T=inf{t≥0|X(t)≤0} and X(T). We also determine the distribution of sup{X(t)|0≤t≤T}.
