生态工业系统研究述评与展望

从生态工业系统模型、特征、分类、实施途径以及生态工业系统与清洁生产关系等方面述评了国内外生态工业系统的研究进展,指出目前国内外研究仅停留在传统产业园区的生态建设上,未来的发展趋势是在工业城镇或更广泛区域构建社会利益相关者(包括政府、企业、社区)共同参与的生态工业系统,并强调注重环境管理工具和高新技术产业在生态工业发展中的作用,以期为生态城市建设战略的研究奠定一定的基础。     

职业技术教育的社会功能

职业技术教育属于教育系统的一个子系统,它的社会功能除了具有一般教育的共同点外,还有促进社会就业进而推动社会经济发展的独特的社会功能。因此,职业技术教育的社会功能还包括社会福利功能和社会整合功能。职业技术教育的这些社会功能,渗透到社会生活的各个方面,日益成为影响人类社会和经济发展的重要因素。同时,这些社会功能在确定职业技术教育的发展方向、培养目标、课程设置、规模速度等方面起着关键作用。     

黄庭坚谪居黔州交游考述

黄庭坚谪居黔州期间,虽出于全身避祸和害怕累及他人的考虑而经常"谢病杜门",但无论是山谷从前的旧交好友,还是在黔中刚结识的新知同僚、巴蜀后学,非但不以罪臣视之,反而主动与之联系并于诗人照拂有加。而诗人亦尽可能地为前来向他请益求教的两川士人提供帮助,尤其乐于为他们指明"进学畜德"之途,对南北文化的交流与传播和当地人才的培养等做出了巨大的贡献。同时,巴蜀士人的人道关怀,不但使诗人得以度过患难,而且也使诗人的思想和创作发生了巨大变化。     

A semi-parametric approach to robust parameter design

Parameter design or robust parameter design (RPD) is an engineering methodology intended as a cost-effective approach for improving the quality of products and processes. The goal of parameter design is to choose the levels of the control variables that optimize a defined quality characteristic. An essential component of RPD involves the assumption of well estimated models for the process mean and variance. Traditionally, the modeling of the mean and variance has been done parametrically. It is often the case, particularly when modeling the variance, that nonparametric techniques are more appropriate due to the nature of the curvature in the underlying function. Most response surface experiments involve sparse data. In sparse data situations with unusual curvature in the underlying function, nonparametric techniques often result in estimates with problematic variation whereas their parametric counterparts may result in estimates with problematic bias. We propose the use of semi-parametric modeling within the robust design setting, combining parametric and nonparametric functions to improve the quality of both mean and variance model estimation. The proposed method will be illustrated with an example and simulations.     

经济增长的源泉：回顾与反思

在一个制度高度稳定的社会中,市场经济有序运行,那么,技术创新就成为最重要的因素。例如,美国在20世纪90年代,信息产业的发展成为美国新经济的发动机。同一时期的中国,尚处于计划经济向市场经济的转型期,制度的不完善成为发展的最大障碍,严肃立法、严格执法成为当时政府的重要任务。     

Refined Inference on Long Memory in Realized Volatility

There is an emerging consensus in empirical finance that realized volatility series typically display long range dependence with a memory parameter (d) around 0.4 (Andersen et al., 2001; Martens et al., 2004). The present article provides some illustrative analysis of how long memory may arise from the accumulative process underlying realized volatility. The article also uses results in Lieberman and Phillips (2004, 2005) to refine statistical inference about d by higher order theory. Standard asymptotic theory has an O(n^-1/2) error rate for error rejection probabilities, and the theory used here refines the approximation to an error rate of o(n^-1/2). The new formula is independent of unknown parameters, is simple to calculate and user-friendly. The method is applied to test whether the reported long memory parameter estimates of Andersen et al. (2001) and Martens et al. (2004) differ significantly from the lower boundary (d = 0.5) of nonstationary long memory, and generally confirms earlier findings.     

民族文化译介的韩礼德功能阐释——以唐诗《怨情》英译文对比分析为例

近年来,国内译学界出现了从功能语法角度对民族文化译介进行分析的新思路,即以韩礼德三大纯理功能为出发点,对中国古典民族文化文本的传译进行系统功能阐释。基于此,本文以李白《怨情》一诗为例,对多位海外译者的英译文从概念功能角度进行了对比分析,旨在借助功能语法折射海外译者译介中国古典民族文化的种种现象,以期进一步证实功能视角阐释民族文化译介的可行性和意义。
