从生成史略论《水浒传》的主题

本文从《水浒传》生成史的角度,将《水浒传》的成书和作品主题的嬗变联系起来,论证梁山故事在流传过程中不断出现的传奇色彩和归正倾向。它是封建社会全社会被压迫者与有志之士的反抗与追求的“交响曲”,是对封建社会后期现实的一种“全景式的综合反映”。

新疆维吾尔族人口的空间分布与变动

新疆维吾尔自治区地处西部边陲,是一个拥有47个民族成分的大家庭,占全国总面积的1/6。维吾尔族是这个大家庭的一员,也是其中人口最多的民族。该民族的形成与发展经历了漫长的历史时期,人口的空间分布状况与变动情况也有其独特的规律性和特点。尤其是新中国成立后50年来,维吾尔族人口发生了巨大的变化。下面我们就来用定性和定量两方面来分析新疆维吾尔族人口的空间分布与变动情况。     

中国城市规模分布及影响因素实证研究

文章应用城市位序—规模法则与分形理论,测算了1999—2008年间分别以城市人口、建成区面积和经济规模表征的中国城市规模分布分维值,对分维值进行了纵向对比分析,并实证分析了影响城市规模的主要因素。研究结果显示：中国城市规模分布具有显著的分形特征,符合城市位序—规模法则;1999—2008年间三种表征的中国城市规模分布分维值均呈现下降趋势;中国城市规模具有明显区域性差异,资本投入、科技水平、产业结构和外资是推动城市规模扩大的重要因素。最后,文章据此提出了发展和完善中国城市规模体系的对策建议。     

中国城镇化模式研究综述

城市化是未来推动经济增长的主导力量。西方经济学关于城市演进的理论上主要有分工演进、推—拉作用和集聚经济理论。众多学者在这三个主要理论指导下,着重以"经济增长"为目标来探讨我国的城镇化模式,并关注于城市规模效应和城市体系建设。但这些研究还缺乏系统的理论指导,城市发展的目标也太过于强调经济增长,未深入探讨以全体居民的福利改进为目标的城镇化可行性路径。     

基于GIS的宁夏人口经济压力空间分布研究

空间分析是深入探索空间特征的重要技术,因此作者利用空间分析中的主成分分析方法和空间自相关分析对宁夏人口经济压力分类及其分布关系进行了深入探索,结果表明,宁夏人口经济压力从北部向南部逐渐增大,在空间分布关系上人口经济压力呈现明显的组团模式,北部区域以银川为核心呈低—低关联模式,南部区域以原州区为核心呈高—高关联模式。     

The manager's role in employees' successful return to work following back injury

Abstract

This study reports on the short-term effects of an educational programme for immediate supervisors on employees' back pain problems. The course was designed to help supervisors more efficiently deal with employees returning to work after being treated for back pain. Forty-seven supervisors who had personnel either undergoing treatment for back pain problems or were candidates for this treatment were invited to attend a one-day course. This educational package consisted of information about back pain and stressed specific behaviours which supervisors could use to help their employees successfully return to work. The results showed that 78% of the supervisors found the course to be satisfactory enough to recommend it to a colleague without hesitation. Furthermore, independent ratings made by the supervisors and their employees suggested that supervisors complied with the recommended programme. Returning employees, moreover, gave their supervisors significantly higher ratings of support than a control group whose supervisors had not attended the educational programme. It was concluded that an educational programme which alters specific supervisory behaviours may be an effective method of assisting employee return to work after treatment for back pain. Further research is needed to determine the long-term effects of such a programme on absenteeism due to illness.     

A New Multicriteria Risk Mapping Approach Based on a Multiattribute Frontier Concept

Invasive species risk maps provide broad guidance on where to allocate resources for pest monitoring and regulation, but they often present individual risk components (such as climatic suitability, host abundance, or introduction potential) as independent entities. These independent risk components are integrated using various multicriteria analysis techniques that typically require prior knowledge of the risk components’ importance. Such information is often nonexistent for many invasive pests. This study proposes a new approach for building integrated risk maps using the principle of a multiattribute efficient frontier and analyzing the partial order of elements of a risk map as distributed in multidimensional criteria space. The integrated risks are estimated as subsequent multiattribute frontiers in dimensions of individual risk criteria. We demonstrate the approach with the example of Agrilus biguttatus Fabricius, a high‐risk pest that may threaten North American oak forests in the near future. Drawing on U.S. and Canadian data, we compare the performance of the multiattribute ranking against a multicriteria linear weighted averaging technique in the presence of uncertainties, using the concept of robustness from info‐gap decision theory. The results show major geographic hotspots where the consideration of tradeoffs between multiple risk components changes integrated risk rankings. Both methods delineate similar geographical regions of high and low risks. Overall, aggregation based on a delineation of multiattribute efficient frontiers can be a useful tool to prioritize risks for anticipated invasive pests, which usually have an extremely poor prior knowledge base.     

解读人与自然的和谐

人与自然和谐包含着丰富和深刻的内涵 ,从理论层面上看 ,它应是人与自然互相适应的辩证统一 ;从实践层面上讲 ,它应是人与自然双方均处于既被改造又应保护的关系之中。必须反对在这个问题上的各种片面的观点与看法     

金诗学唐的历程

金代诗歌在受苏轼等宋代诗人的影响之外 ,也受到唐诗的浸润。本文依据金诗发展变化的自身情况 ,考察了金诗学唐的历程。文中将金诗学唐分为金初“借才异代”时期、“国朝文派”时期、金代后期等三个阶段 ,做了比较详细的论述 ,从一个方面展示了金诗发展的轨迹 ,揭示了金诗的某些重要特点 ,对于我们深入地认识金诗是有裨益的
