骚、赋文体辨——兼说屈作不当名赋

本文认为 ,骚、赋分别为不同的文体 ,不应混为一谈 ,屈原之作不当以赋名之。文章着重从骚、赋产生的历史状况 ,骚、赋体性之差别 ,骚、赋之流变 ,说明二者之不同 ,其中对骚、赋体性之别论述较为具体细微。文章最后对与此相关的几个问题 ,如刘勰、萧统对骚、赋的分辨 ,汉人何以称屈作为赋 ,以及骚体赋进行了简要论述。此文有助于解决对屈原之作称名混乱的状况     

居住分异与社会距离

通过对一个新建社区的形成过程和居住现状的考察,分析了国内"居住分异"的社会分化现象。通过数据分析发现,居住分异以后,群体分化程度被强化了,它使居民之间的社会距离扩大、疏离感增强。这种状况不利于社会团结与和谐社会的建设。我国正处在城市化高速发展的进程中,如果没有明确的政策干预,任由房地产市场按照这样的情况发展下去,居住分异与社会距离问题会变得更加严重。     

城市居住空间结构的分异研究——以杭州市为例

居住空间是城市社会空间的一个重要的组成部分。随着城市化的大规模扩展,城市居住空间的结构分异已然成为不争的客观事实。通过对杭州市商品住宅面积、类型和价格分异的讨论,勾勒出目前城市居住空间结构分异的特点。在此基础上,透过阶层分化与居住空间结构之间的关系,来探究居住空间结构分异的动力机制,以便提供一些居住融合的策略性建议。     

高校学报项目化管理探究——以《辽宁工程技术大学学报》为例

为了进一步提高高校学报出版活动效率,采用项目管理的方法对高校学报出版活动进行研究。分析了高校学报项目化管理的可行性。针对高校学报出版发行活动,制定了一套切实可行的操作计划,运用WBS方法对学报出版项目工作进行层层分解,项目责任矩阵图将所分解的工作落实到有关部门或个人。为确保能够在规定的时间内实现期刊出版项目的目标,编制了学报出版项目的甘特图,利用Project软件对现有人力资源和进度进行调配,使学报出版工期在原来50天的基础上缩短了16天。可见通过运用科学的项目管理工具对高校学报出版发行活动进行管理,使得高校学报管理工作更加规范化、科学化。     

一种基于加权F-范数的半正定矩阵的逼近方法

正定性是许多金融预测模型的重要假设前提，然而从实际样本中得到的相关系数矩阵并不能保证其正定性。为此在介绍如何根据样本设定相关系数矩阵以及范数逼近原理的基础上，如何根据该原理找到与之最接近的相关系数矩阵，即最接近的单位对角半正定对称矩阵。通过实证，验证了其方法的有效性。     

The predictive distributions of thinning‐based count processes

This paper shows that the term structure of conditional (i.e. predictive) distributions allows for closed form expression in a large family of (possibly higher order or infinite order) thinning‐based count processes such as INAR(p), INARCH(p), NBAR(p), and INGARCH(1,1). Such predictive distributions are currently often deemed intractable by the literature and existing approximation methods are usually time consuming and induce approximation errors. In this paper, we propose a Taylor's expansion algorithm for these predictive distributions, which is both exact and fast. Through extensive simulation exercises, we demonstrate its advantages with respect to existing methods in terms of the computational gain and/or precision.     

Profile of the Present Slovak Society and its Regional Differences

The article is the first attempt in assessment of the development and the present situation of social structure and stratification in Slovakia. Its principal aim is to develop the profile of the present society in Slovakia, which reflects the pace and complexity of the transformation process and its impact on society. Processing of Micro census data from 2003 led to creation of the profile of society in Slovakia at the national level based on income distribution but also knowledge on regional societies and differences between them were obtained. It was found out that the present profile of the society in Slovakia is pear-shaped which means strong representation of lower strata and weaker representation of higher middle and high strata. The profile disclosed some specific features and inconsistencies in the present society of Slovakia, which were, and still are determined by many non standard past and present phenomena and processes often disguised by reforms. The information drawn in regions has facilitated identification of the basic nature and structure of regional societies, some of their specific features and negative elements and to demonstrate their highly differentiated character.

一类带耗散项非线性波动问题的研究

对一类带耗散项非线性波动方程进行了研究,用“参数微分法”,得到其解析近似解。其结果可用于研讨摄动对原物理问题的解的影响,类似的问题在许多动力学问题物理解的数值定性分析及应用WKB方处理时也会常遇到。     

重新思考打造家电企业竞争优势的战略基础

差异化是竞争优势的重要来源。过去企业依靠成本更低或特色更多谋求竞争优势。进入21世纪,品牌和速度成为获取竞争优势的战略基础。我国家电企业应以差异化品牌战略为主导,实施产品品牌战略和企业品牌战略,并战略性再造供应链和价值链,以形成迅速应对目标市场、能够敏捷反应的速度优势。     

Hotelling模型再探讨

文章修改Hotelling模型的基本假定,假定厂商边际生产成本为正,交通成本由消费者负担,厂商区位可以为内生变量,也可以为外生变量,在此假定前提下,分析厂商的最优的区位—价格策略,以探讨最大差异化原则或者最小差异化原则何时成立,或者不成立。
