与马克思不同,韦伯从宗教的角度分析了其对于资本主义经济发展所起到的作用。这种作用实际上不止于经济领域,而且涉及政治领域。作者还对韦伯的分析方法进行了评估,认为韦伯并没有否认经济因素对社会发展所起的决定作用,新教与资本主义之间只是存在着一种内在的亲和关系。  相似文献

消防工作中涉及到大量具有空间分布特性的信息,用传统的方法去收集、管理、分析这些信息已经无法满足目前消防工作的需要.运用日趋成熟的GIS技术建设现代化消防指挥中心,对于提高消防快速反应能力,保护国家人民的生命财产安全具有十分重要的意义。  相似文献

本文介绍了利用典型气体泄漏扩散模型开发基于GIS的城市易燃易爆有毒气体泄露事故应急决策系统的方法.首先,我们采用SuperMap提供的控件在VC6平台上利用COM( )技术开发建立GIS系统平台;然后根据不同情况选取几种气体扩散模型,计算出气体扩散的趋势和范围;在此基础上分析计算出气体扩散范围内的受灾群众,并进一步给出受灾群众的疏散方法.系统决策结果可为决策人员做出合理的决策提供参考.  相似文献

Using Dasymetric Mapping for Spatially Aggregated Crime Data   总被引:1,自引:0,他引:1  
With availability of crime data to the public via sources such as the Uniform Crime Reports, and increasing geographic information system (GIS) capabilities for mapping crime, macro-level studies of crime have advanced knowledge of how crime is distributed over large areas. Choropleth mapping, commonly used in macro-level studies, visually displays data by assigning the number of crimes or crime rate to the corresponding spatial unit and using different shades or textures for each value or classified values creating a thematic map. However, crime incidents or crime rates are not dispersed evenly within spatial units, and choropleth mapping masks the underlying nuances of the distribution. Artificial boundaries, along with variations in the size of the unit of analysis, can further distort the true distribution of crime. Dasymetric mapping provides a methodology for refining the distribution of crime within a spatial unit. It does so by using additional data, such as land use and census data, to provide a realistic estimate of how crime may be distributed within the units of analysis. Dasymetric mapping is also useful in creating density maps to reveal clusters of crime normally masked with choropleth maps. This paper will show how dasymetric mapping can estimate the spatial distribution of aggregate level residential burglary within political boundaries in Massachusetts based on land use and housing data.  相似文献

A hyperlink (or simply a link) is a citation of an electronic address where further information can be found but, additionally, navigates the surfer almost instantaneously to material hosted anywhere on the Internet at a mere click of a mouse. Controversy arises because either the composition or functionality of the hyperlink can potentially infringe property rights of the claimant. Many have written about the hyperlink as a navigation tool authorising or contributing to infringement of copyright by a third party.1This article concentrates on the composition of an external hyperlink, as a citation. Part 2 outlines the nature of Internet communication and explains why hyperlinks are often controversial. Part 3 asserts when copyright subsists in original literary works, but because a hyperlink may incorporate diverse formats, this part also addresses the protection of other works including the issue of composite works covered under section 1(1) of Copyright, Design and Patents Act, 1988. Applying copyright principles, it suggests that a hyperlink reproducing an identifiable part of a web page capable of standing apart from its context can infringe copyright in the web page containing the part. That said the claimant might face difficulty in demonstrating that the work is substantive or, where the hyperlink consists of diverse inputs, in categorising the subject matter. Part 4 acknowledges the significance (electronic) collections and therefore defines a database falling within the Databases Directive.2 It then highlights challenges presented by copyright and sui generis right relating to databases concluding that reproducing an identifiable part of author compiled work can infringe copyright and/or sui generis right therein but the same is not true of search engine generated returns. Part 5 concedes that, in practice, subsistence of copyright and/or sui generis right is open to challenge because the part reproduced in a hyperlink may not be substantive, may not easily fit into the category of protected subject matter or lacks ‘substantial investment.’ Nevertheless, it argues that proving infringement in an identifiable part of a web page reproduced in a hyperlink remains the most viable option for indirectly controlling access to the target page, which may itself be unprotected by copyright.  相似文献

Research has shown that mapping techniques are useful in forecasting future crime events. However, the majority of prospective mapping techniques has focused on the event-dependent influence of instigator incidents on subsequent incidents and does not explicitly incorporate the risk heterogeneity of the setting. The study here discussed is a modest attempt to address this issue by using a two-step process: first, using risk terrain modeling, we operationalized the “environmental backcloth,” (the risk heterogeneity of an area) to forecast locations of residential burglaries in the urban city of Newark, New Jersey. Second, using the near repeat calculator, we assessed the variability of underlying risk between different types of residential burglaries. A discussion of the findings and the joint utility of these approaches is provided.  相似文献
