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。     

文学性言外行为的隐蔽性分析

文学性言外行为与普通交际性语言的言外行为有所不同 ,文学性言外行为的隐蔽性是由于文学标准、作家对社会文化政治情况的考虑、文学符号的艺术性以及作家对读者群定位造成的     

论刘勰文学批评的“文本”精神

刘勰的文学批评有别于先秦两汉时期的“以德为本”的文学批评。贯穿刘勰文学批评始终的是“以文为本”的精神,“文”是刘勰文学批评理论的核心,也是刘勰文学批评方法论依据。刘勰文学批评中的“文本”精神是我国文学批评走向自觉的重要标志。     

当代中国文学思潮的特点与模式

文学思潮是一个时代的文学创作潮流中所表现出来的那个社会的时代精神和社会风尚,以及那个时代起主导作用的文学创作的理论和方法。文学思潮有以下几个特点一、深层性;二、理论性;三、群体性;四、时段性;五、实践性。对于划分和命名文学思潮,应该尽可能地宽容。然而,宽容并不是没有原则。当代中国文坛独特的结构和制度,决定了当代文学思潮的特点。主要表现在一、文学理论和创作极度密切的关系;二、文学思潮少有自发产生的,基本上是自觉的、自上而下提倡的;三、由于基本是自觉的,所以是理性的。     

现代传媒与现代散文辨体

现代散文的文类向来比较混杂,人们的认识也不一致,本文从现代传播媒体与散文形成与发展的关系出发,探讨现代散文的文类意识,并从散文文体的角度进行了必要的辨体.现代传媒对散文文体的形成产生了明显的影响,因而古代文章的分类在现代媒体中失去了"辨体"的意义,现代传媒为现代散文辨体提供了理论依据,现代散文文类大体可以分为叙事类、杂感类、小品类、杂体类.

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.

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。
