柯尔律治的莎士比亚评论综述

文章梳理了柯尔律治关于莎士比亚评论的基本观点,展示了柯尔律治对莎士比亚作品评论的独具匠心之处。柯尔律治"实践性批评原理"的提出,对"天才"、"诗性想像力"的分析,对"有机统一原则"的阐释,对莎士比亚戏剧人物的评述等都对后世产生了深远的影响,也引起了后人极大的争议。     

以生命的独特性与稀缺性修正泰勒的生命中心主义

以泰勒为代表的生命中心主义作为当代环境哲学的重要理论之一,从所有生命都具有自身善的事实结合“以生命为中心的世界观”的规范性论断对所有生命都应受到道德关怀进行了严密论证,并据此提出了四条人类应当履行的道德原则。泰勒的论证是有说服力的,但由于其侧重于生命个体,缺乏对生命整体的观察维度,忽视了某些对于生命来说具有重要意义的事实,使得其所推论出的规范性道德原则存在严重问题。其中的“不干涉原则”使得生命之间没有互相帮助的义务,人类不能介入那些能够毁灭生命的环境灾难以协助生命完成其自我保存的目的;而“不伤害原则”也几乎否定了人类所有的可能损毁生命的实践活动。面对这些问题,本文的解决思路如下:首先,从阐发泰勒的“拥有自身善的实体”的概念出发,分析生命具有目的这种独特性,并指出了生命所具有的三种目的,即自我保存的目的、作为实现自我保存目的的手段性目的、独立于自我保存的目的;其次,提出由于难以生产、分布范围极小、存在的偶然性而导致的生命的稀缺性,以及在诸多环境灾难面前表现出的脆弱性,推论出生命之间应当具有的积极责任;最后,论证了这种积极责任的必要性和可行性,认为基于生命的稀缺性和脆弱性,这种义务是紧迫的和必要的,而在履行这一义务的同时,人类将获得可能损毁其他生命的实践活动的正当性,并且由于这种正当性能够使人类产生按照积极责任而行的心理动机而使这种积极义务具有了可行性。由此,泰勒的生命中心论所面对的两个问题得以解决,对之的修正也由于提出的积极义务具有必要性和可行性而得以完成。

科学元典与文化元典--泰勒与孔子的管理思想要点比较

泰勒是西方科学管理之父,他研究的是企业管理,其理论的基本特点是重视"规制";孔子为中国文化管理之父,其着眼点在经世治国,亦即公共管理,其思想的焦点是"和治".规制强调物本、理智、常效、他律与刚性;和治强调民本、亲情、长效、自律与柔性.泰勒思想作为科学管理元典已有共识,孔学在文化上的同等地位也有历史依据与逻辑依据.孔子是最早在管理中重视人文关怀的人之一,其对群体性的关注,也与现代文化管理追求是一致的.     

Asymptotic test statistics for coefficients of variation

A one-sample asymptotically normal test statistic Is derived for testing the hypothesis that the coefficient of variation of a normal population is equal to a specified value. Based on this derivation, an asymptotically noraml two-sample test statistic and an asymptotically chi-square k-sample test statistic are derived for testing the hypothesis that the coefficients of variation of k ≥2 normal populations are equal. The two and k-sample test statistics allow for unequal sample sizes. Results of a simulation study which evaluate the size and power of the test statistics and compare the test statistics to earlier ones developed by McKay (1932) and Bennett (1976) are presented.     

Sampled autocovariance and autocorrelation results for linear time processes

We derive an exact formula for the covariance between the sampled autocovariances at any two lags for a finite time series realisation from a general stationary autoregressive moving average process. We indicate, through one particular example, how this result can be used to deduce analogous formulae for any nonstationary model of the ARUMA class, a generalisation of the ARIMA models. Such formulae then allow us to obtain approximate expressions for the convariances between all pairs of serial correlations for finite realisations from the ARUMA model. We also note that, in the limit as the series length n → ∞, our results for the ARMA class retrieve those of Bartlett (1946). Finally, we investigate an improvement to the approximation that is obtained by applying Bartlett's general asymptotic formula to finite series realisations. That such an improvement should exist can immediately be seen by consideration of out results for the simplest case of a white noise process. However, we deduce the final improved approapproximation, for general models, in two ways - from (corrected) results due to Davies and Newbold (1980), and by an alternative approach to theirs.     

数据修订、实时估计与时变参数货币政策规则抉择

本文拓展构建了后顾、同期和前瞻三种类型的货币政策规则,并基于实时数据和最终数据实证分析数据修订和实时估计对货币政策参数的影响效应。研究结果发现,数据修订对泰勒规则的影响取决于不同模型,而且在三种模型设定中,盯住产出缺口和通胀目标的时变参数均在不同程度上受数据修订的影响。特别是,对于最终数据,采用同期性货币政策规则展开估计最为有效;而对于实时数据,则基于后顾性货币政策规则模型估计是最佳的。最后,本文在数据选择和模型匹配上提出相应的对策建议。     

Can alternative Taylor-rule specifications describe Federal Reserve policy decisions?

We look at how well several alternative Taylor-rule specifications describe Federal Reserve policy decisions in real time, using the newly developed Giacomini and Rossi (2007) test for non-nested model selection in the presence of (possible) parameter instability. Further, we isolate those Taylor-rule features that are most important for achieving relatively strong real-time performance. Key features of our preferred rule, which is robust to changing economic conditions, are the partial adjustment of the federal funds rate toward an equilibrium rate that depends on the unemployment rate and forward-looking inflation measures. We conclude by presenting an empirical application to show the policy relevance of our preferred rule in the context of the 2008–2009 recession.
