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。     

A new generalized Weibull distribution in income economic inequality curves

Researchers have been developing various extensions and modified forms of the Weibull distribution to enhance its capability for modeling and fitting different data sets. In this note, we investigate the potential usefulness of the new modification to the standard Weibull distribution called odd Weibull distribution in income economic inequality studies. Some mathematical and statistical properties of this model are proposed. We obtain explicit expressions for the first incomplete moment, quantile function, Lorenz and Zenga curves and related inequality indices. In addition to the well-known stochastic order based on Lorenz curve, the stochastic order based on Zenga curve is considered. Since the new generalized Weibull distribution seems to be suitable to model wealth, financial, actuarial and especially income distributions, these findings are fundamental in the understanding of how parameter values are related to inequality. Also, the estimation of parameters by maximum likelihood and moment methods is discussed. Finally, this distribution has been fitted to United States and Austrian income data sets and has been found to fit remarkably well in compare with the other widely used income models.     

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。

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     

黄土高原退化生态系统的恢复重建方略

综观黄土高原植被恢复重建历史，最为流行的观点当属“以古证今”和“以山证原”两种观点。而事实情况是，古代山地的植被分布，只能提供一些植物恢复重建可咨借鉴的旁证资料。对于黄土高原退化生态系统，其植被建设只能立足于现实生态环境条件，适地适树（草）适法，方能有效恢复和重建植被，以发挥其多方面的生态经济功能。植被恢复重建在不同类型区有不同模式，总体应由东南部的以乔灌为主，向西北部的以灌草为主逐步过渡。植被恢复重建目标应是建立与现实生态环境最为适应的人工植被类型。植被恢复、植被重建和植被保护3个方面相辅相成，是黄土高原地区植被建设不可分割的3条主要途径。     

Assessing accuracy of a continuous screening test in the presence of verification bias

Summary.  In studies to assess the accuracy of a screening test, often definitive disease assessment is too invasive or expensive to be ascertained on all the study subjects. Although it may be more ethical or cost effective to ascertain the true disease status with a higher rate in study subjects where the screening test or additional information is suggestive of disease, estimates of accuracy can be biased in a study with such a design. This bias is known as verification bias. Verification bias correction methods that accommodate screening tests with binary or ordinal responses have been developed; however, no verification bias correction methods exist for tests with continuous results. We propose and compare imputation and reweighting bias-corrected estimators of true and false positive rates, receiver operating characteristic curves and area under the receiver operating characteristic curve for continuous tests. Distribution theory and simulation studies are used to compare the proposed estimators with respect to bias, relative efficiency and robustness to model misspecification. The bias correction estimators proposed are applied to data from a study of screening tests for neonatal hearing loss.     

Fuzzy K-means clustering models for triangular fuzzy time trajectories

We focus our attention on the classification of fuzzy time trajectories with triangular membership function, described by a given set of individuals. To this purpose, we adopt a fullyinformational approach, explicitly recognizing the informational nature shared by the ingredients of the classification procedure: the observed data (Empirical Information) and the classification model (Theoretical Information). In particular, by supposing that the informational paradigm has a fuzzy nature, we suggest three fuzzy clustering models allowing the classification of the triangular fuzzy time trajectories, based on the analysis of the cross sectional and/or longitudinal characteristics of their components (centers and spreads). Two applicative examples are illustrated.
