沈从文文化批评中的分裂性特征

沈从文文化批评的目的是试图在"古典"和"现代"之外寻求一个第三点来构筑他的文化理想。这样的文化理想不是任何凝固、僵滞的模式,而是要体现出生命的鲜活和流动。但是他的努力失败了,这个第三点是无法实现的。因此在40年代,他转向了"抽象的抒情"。这一转向表明他所用来表达其文化观念的自我、静观、自然、人性、神性等等范畴的内在分裂。     

德国空间规划与城市规划协同机制及其比较研究

德国空间规划的管理体制注重构造空间整治规划与城市建设指导规划的协同机制,它集中体现在协同机制的法律基础、协同机制的组织制度基础、协同机制的程序制度基础以及实现协同机制的途径与工具等方面。从德国空间规划协同机制角度出发,与我国空间规划现行的机制进行比较研究,探讨改善我国空间规划协同机制诸问题。     

陕西省入境旅游产业结构分析与优化研究

针对近年来陕西省入境旅游产业发展缓慢的现状,选取了与入境旅游产业相关的8个主要部门6年来的收入增长变化数据,运用偏离-份额分析方法的Esteban–Marquillas拓展模型对陕西省入境旅游产业结构进行分析。结果表明:陕西入境旅游产业结构基本趋于合理,但总增长速度趋于缓慢,整体产业竞争优势不强。其中长途交通、住宿、餐饮、商品销售等部门专业化程度较高、资源配置程度较好,但是缺乏相对长远的竞争优势,而游览、娱乐、邮电通讯等部门具有很强的竞争优势。并根据此结论,提出了有关优化陕西省入境旅游产业结构的5点对策。     

在整合创新中构建和谐伦理文化

面对中国传统伦理文化、西方现代伦理文化和马克思主义伦理文化的三元并行现象,我们不能绝对地肯定或否定任何一种文化,而应当从实际出发,采取"以'马'为主,融合中西,贯通古今,多元一体,整合创新"的方针,让马克思主义的伦理文化在政治和意识形态领域继续起主导作用;让西方现代文化中的自由平等精神在经济领域发挥激励作用;让中国传统伦理文化在个人生活、家庭生活、职业生活和社会公共生活领域发挥更多的积极作用.通过这样的分域、分层整合,使这三种伦理文化各得其位,各显其能,扬长避短,整合创新,共同为构建和谐社会提供服务.

Mixed integer (0–1) fractional programming for decision support in paper production industry

This paper presents an effective and efficient method for solving a special class of mixed integer fractional programming (FP) problems. We take a classical reformulation approach for continuous FP as a starting point and extend it for solving a more general class of mixed integer (0–1) fractional programming problems.To stress the practical relevance of the research we focus on a real-life application in paper production industry. The constantly advancing physical knowledge of large scale pulp and paper production did have a substantial impact on an existing DSS in which mixed integer (0–1) fractional programming is introduced. We show that the motivation to solve a real-life fractional programming problem can provide the basis for a new approach in a new context that has an added value of its own, even outside the given application area. We describe the main characteristics of the DSS, the necessity to develop a non-iterative solution procedure and demonstrate both the effectiveness and efficiency of the proposed approach from practical data sets.     

The exponential distribution analog of the Grubbs–Weaver method

Abstract

Grubbs and Weaver (1947 Grubbs, F. E., and C. L. Weaver. 1947. The best unbiased estimate of population standard deviation based on group ranges. Journal of the American Statistical Association 42 (238):224–41. doi: 10.2307/2280652.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) suggest a minimum-variance unbiased estimator for the population standard deviation of a normal random variable, where a random sample is drawn and a weighted sum of the ranges of subsamples is calculated. The optimal choice involves using as many subsamples of size eight as possible. They verified their results numerically for samples of size up to 100, and conjectured that their “rule of eights” is valid for all sample sizes. Here we examine the analogous problem where the underlying distribution is exponential and find that a “rule of fours” yields optimality and prove the result rigorously.
