论高等学校科技工作的地位与作用

高等学校科技工作具有培养社会所需的高水平的现代人才、催生科技成果的双重职能作用。因此 ,正确处理教学与科技工作的关系 ,确立科技发展的观念 ,对高校建设发展具有非常重要的意义     

一般Gauss－Markov模型下一般可估函数的线性充分性和线性完全性

发展了Ｂａｋｓａｌａｒｙ和Ｄｒｙｇａｓ提出的一般Ｇａｕｓｓ－Ｍａｒｋｏｖ模型中线性充分性、最小充分性和完全性的概念，用Ｒａｏ的最小二乘统一理论，给出了这些概念的刻划定理。     

公共物品的提供模式及政府管制的效率比较

随着技术水平以及人们收入水平的不断提高,市场力量不断进入到公共物品的提供领域,然而由于公共物品对于社会公平、公正带来的重要影响,政府会对市场提供公共物品时进行有效管制,而最主要的管制模式就是进行价格管理。文章利用Wickstro¨m(2001)的模型,分析了政府在对市场提供公共物品进行管制时的效率问题,指出在成本信息不对称时政府管制的效率可能很低,反而给社会福利造成了比较大的损失,同时企业利润也受到影响。     

拓展服务功能,深入挖掘高校档案价值内涵

Uncertainty Analysis for Computer Model Projections of Hurricane Losses

Projecting losses associated with hurricanes is a complex and difficult undertaking that is wrought with uncertainties. Hurricane Charley, which struck southwest Florida on August 13, 2004, illustrates the uncertainty of forecasting damages from these storms. Due to shifts in the track and the rapid intensification of the storm, real-time estimates grew from 2 to 3 billion dollars in losses late on August 12 to a peak of 50 billion dollars for a brief time as the storm appeared to be headed for the Tampa Bay area. The storm hit the resort areas of Charlotte Harbor near Punta Gorda and then went on to Orlando in the central part of the state, with early poststorm estimates converging on a damage estimate in the 28 to 31 billion dollars range. Comparable damage to central Florida had not been seen since Hurricane Donna in 1960. The Florida Commission on Hurricane Loss Projection Methodology (FCHLPM) has recognized the role of computer models in projecting losses from hurricanes. The FCHLPM established a professional team to perform onsite (confidential) audits of computer models developed by several different companies in the United States that seek to have their models approved for use in insurance rate filings in Florida. The team's members represent the fields of actuarial science, computer science, meteorology, statistics, and wind and structural engineering. An important part of the auditing process requires uncertainty and sensitivity analyses to be performed with the applicant's proprietary model. To influence future such analyses, an uncertainty and sensitivity analysis has been completed for loss projections arising from use of a Holland B parameter hurricane wind field model. Uncertainty analysis quantifies the expected percentage reduction in the uncertainty of wind speed and loss that is attributable to each of the input variables.     

谈桥梁的技术美

桥梁技术美已成为当前工程师日益关注的课题。理解桥梁技术的产生及其组成因素;现代桥梁设计需要设计师具有美学修养;桥梁方案的设计要有建筑师的参与,才能更好地体现桥梁内在的美学价值。     

论西部地区地方政府在构建和谐社会中的主导作用

西部地区构建和谐社会是一个长期的、逐渐的过程.地方政府作为构建和谐社会的主体,承担着更为繁重的任务,尤其是经济欠发达的西部地区.构建社会主义和谐社会,地方政府必须调动一切积极因素,增强全社会的创造活力;发挥引导、协调和支持的作用,广泛调动社会各方面的积极性,调整好各方面的利益关系,维护和实现社会公平;营造良好的社会氛围,形成和谐相处的人际环境;加强社会建设和管理,切实维护社会稳定.必须深化各项改革,形成一个促进地区经济社会协调发展的体制机制,为构建社会主义和谐社会提供有力的体制保障.     

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.     

试论培训后勤职工与发挥后勤德育功能

高校后勤具有很强的德育功能。培训高校后勤职工具有多方面的重要性。高校后勤工作具有繁杂性,微利服务性和部分福利性等特点。队伍和素质参差不齐、年龄老化、学历偏低、劳动技术较弱和部分职工打工仔意识强,主人翁意识弱等现状表现出了搞好后勤职工培训的必要性和紧迫性。因此,要对后勤职工搞好四个方面的培训,通过四条途径发挥其德育功能。
