美好抑或悲哀:旅游演艺的文化真实性研究

文化是旅游演艺的灵魂,旅游演艺即为通过对真实的地域文化进行抽离、截取、裁剪等艺术性加工所形成的具有舞台美感的旅游表演,并使真实的文化转变成舞台上的文化。由于利益诉求不同,旅游演艺相关各方对于文化真实性的关注角度存在一定差异。旅游演艺在对地域文化进行艺术加工的同时,也在对地域文化进行着解构与重构。地域文化真实性在解构与重构过程中发生改变,也使得旅游演艺相关各方对文化真实性产生了不一样的理解。尽管地域文化真实性因旅游演艺的介入而发生变化这一客观事实引起了一定的悲哀性慨叹,但总体而言旅游演艺重构或生产"新文化"这一过程既是美好的现实,更是美好的"真实",另外,这类"新文化"同样值得尊重,其是地域文化变迁过程中的真实性存在。     

文学意义的消解与重建

在商品化和信息化的时代大潮冲击下 ,文学面临着意义的流失与消解。文学的这种现状是与整个人类文化的困境紧密相关的 ,是人类发展特殊阶段上的必然产物。中国当代文学应致力于意义的探寻与重建 ,这表现为在对现实的清醒认识的基础上对理想的重新肯定 ,对现实中的物欲的批判性把握 ,以及对人类生存意义的重新认识。     

论网络环境下的高校校园文化建设

网络正在改变人们的思想观念和行为方式。网络发展也给高校校园文化带来新的机遇和挑战 ,高校校园文化建设只有顺应时代潮流 ,调整思路 ,趋利避害 ,才能把握主动 ,使校园文化发挥应有的作用     

互联网与文化重构及社会分化

互联网的出现不仅丰富了文化的表现形式 ,而且丰富了文化的基础 ,丰富了人们对真理、理性、伦理等文化基本矛盾的认识。互联网作为一种新的文化形态主要不是依据理论的完整性 ,而是依靠它在传播过程中的文化张力来实现的。互联网的出现导致了文化的多元化 ,推动了个人主义 ,冲击了传统文化的主导地位 ,冲击了传统的主流媒体赖以存在的稳定的文化环境 ,冲击了主流文化推崇的文化价值和伦理价值体系。

Low dose risk estimation via simultaneous statistical inferences

Summary.  The paper develops and studies simultaneous confidence bounds that are useful for making low dose inferences in quantitative risk analysis. Application is intended for risk assessment studies where human, animal or ecological data are used to set safe low dose levels of a toxic agent, but where study information is limited to high dose levels of the agent. Methods are derived for estimating simultaneous, one-sided, upper confidence limits on risk for end points measured on a continuous scale. From the simultaneous confidence bounds, lower confidence limits on the dose that is associated with a particular risk (often referred to as a bench-mark dose ) are calculated. An important feature of the simultaneous construction is that any inferences that are based on inverting the simultaneous confidence bounds apply automatically to inverse bounds on the bench-mark dose.     

历史民族志《溪蛮丛笑》论略——兼论作者朱辅其人

《溪蛮丛笑》一书以条目体例形式记述了公元 12世纪时沅江流域各民族的风俗习惯、土产方物、文物古迹 ,是研究这一时期湘西民族史及历史民族文化状况的珍贵资料。原书作者朱辅为南宋人 ,其生卒年代、仕履经历及其人品才识的具体情况史料缺载 ,本文运用历史人类学的理论和方法 ,借助《溪蛮丛笑》一书本身和叶钱为该书所作序言及其他相关零星资料 ,尽可能对朱辅的生平、为人品格和才情学识加以大致复原     

Benchmark Analysis: Shopping with Proper Confidence

We discuss the issue of using benchmark doses for quantifying (excess) risk associated with exposure to environmental hazards. The paradigm of low-dose risk estimation in dose-response modeling is used as the primary application scenario. Emphasis is placed on making simultaneous inferences on benchmark doses when data are in the form of proportions, although the concepts translate easily to other forms of outcome data.     

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。     

Bayesian analysis of elapsed times in continuous‐time Markov chains

The authors consider Bayesian analysis for continuous‐time Markov chain models based on a conditional reference prior. For such models, inference of the elapsed time between chain observations depends heavily on the rate of decay of the prior as the elapsed time increases. Moreover, improper priors on the elapsed time may lead to improper posterior distributions. In addition, an infinitesimal rate matrix also characterizes this class of models. Experts often have good prior knowledge about the parameters of this matrix. The authors show that the use of a proper prior for the rate matrix parameters together with the conditional reference prior for the elapsed time yields a proper posterior distribution. The authors also demonstrate that, when compared to analyses based on priors previously proposed in the literature, a Bayesian analysis on the elapsed time based on the conditional reference prior possesses better frequentist properties. The type of prior thus represents a better default prior choice for estimation software.
