学习国外经验搞好土地规划

土地是财富之母,是人类社会赖以生存和发展的基础.随着我国经济建设的飞速发展和城市化进程的加快,城市建设用地与农业用地之间的矛盾日益尖锐,城市土地利用结构和布局不合理的问题也相当突出,这些都迫切要求进行科学合理的城市土地利用总体规划.城市土地利用总体规划是在一定时期内对城市范围内全部土地的综合利用所做的统筹安排和长远规划.它包括对城市建设用地与城市非建设用地的规划,当然同一级的农业区划也包括对这部分农业用地的规划.搞好城市土地利用总体规划意义重大,它能有效调节城市建设用地与农业用地之间的矛盾;有利于调整城市土地的结构和布局;也能加强城市土地供给的宏观调控,促进城市房地产业的健康发展.     

Empirical likelihood confidence intervals for the mean of a population containing many zero values

If a population contains many zero values and the sample size is not very large, the traditional normal approximation‐based confidence intervals for the population mean may have poor coverage probabilities. This problem is substantially reduced by constructing parametric likelihood ratio intervals when an appropriate mixture model can be found. In the context of survey sampling, however, there is a general preference for making minimal assumptions about the population under study. The authors have therefore investigated the coverage properties of nonparametric empirical likelihood confidence intervals for the population mean. They show that under a variety of hypothetical populations, these intervals often outperformed parametric likelihood intervals by having more balanced coverage rates and larger lower bounds. The authors illustrate their methodology using data from the Canadian Labour Force Survey for the year 2000.     

Significant Factors of Aviation Insurance and Risk Management Strategy: An Empirical Study of Taiwanese Airline Carriers

Aviation insurance premiums have become a heavy burden for the airline industry since September 11, 2001. Although the industry must constantly balance its operations between profitability and safety, the reality is that airlines are in the business of making money. Therefore, their ability to reduce cost and manage risk is a key factor for success. Unlike past research, which used subjective judgment methods, this study applied quantitative historical data (1999–2000) and gray relation analysis to identify the primary factors influencing ratemaking for aviation insurance premiums. An empirical study of six airlines in Taiwan was conducted to determine these factors and to analyze the management strategies used to deal with them. Results showed that the loss experience and performance of individual airlines were the key elements associated with aviation insurance premiums paid by each airline. By identifying and understanding the primary factors influencing ratemaking for aviation insurance, airlines will better understand their relative operational strengths and weaknesses, and further help top management identify areas for further improvement. Knowledge of these factors combined with effective risk management strategies, may result in lower premiums and operating costs for airline companies.     

论电子政务对行政决策的影响

电子政务是一场运用新的现代网络技术、信息技术为手段对传统政务管理模式的深刻变革。行政决策是行政管理的核心,贯穿于行政管理的全过程。电子政务的应用与推广,必将改变行政决策的环境、条件、技术与状态,从而深刻地影响着行政决策。要使电子政务对行政决策的影响发挥出应有的最大的效能,就必须理性运用电子政务,最大程度强化电子政务对行政决策的正面影响,最大程度弱化电子政务对行政决策的负面影响。

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。     

Marginal and association regression models for longitudinal binary data with drop‐outs: A likelihood‐based approach

Longitudinal data often contain missing observations, and it is in general difficult to justify particular missing data mechanisms, whether random or not, that may be hard to distinguish. The authors describe a likelihood‐based approach to estimating both the mean response and association parameters for longitudinal binary data with drop‐outs. They specify marginal and dependence structures as regression models which link the responses to the covariates. They illustrate their approach using a data set from the Waterloo Smoking Prevention Project They also report the results of simulation studies carried out to assess the performance of their technique under various circumstances.

沿海经济带建设:加快苏北现代化进程的新支点

地处中国东部开放窗口的江苏沿海经济带,纵贯苏中、苏北两个区域,覆盖南通、盐城和连云港3市,面积3万多平方公里,人口2018万,分别占全省的29.2%和27.9%.但是,它的国内生产总值和财政收入2000年只有1584.8亿元和99.0亿元,分别占全省的18.5%和11.5%.经济落后与其所处区位极不相称.面对新世纪、新形势和新要求,江苏必须进一步增强发展苏北的使命感和紧迫感,通过强力推进沿海经济带建设,切实如快苏北现代化进程.
