In-car satellite navigation systems (SatNavs) are among the first products based on geographic information systems to have widespread fashionable appeal. In the United Kingdom, portable versions that are easily installed on the dashboard or front windshield have become a popular vehicle accessory. As prices have fallen, demand has increased over the last few years to the point that SatNavs might soon achieve the ubiquity of in-car entertainment systems. The rise of popularity of SatNavs, however, has also brought with it increased vulnerability to vehicle crime. Our analysis for the London borough of Newham shows a threefold increase in SatNav theft that occurred from 2005–2006 to 2006–2007. This is not limited to SatNavs being on display, but criminals also looking for the telltale signs of suction marks on the windshield indicating that a portable SatNav might be in the glove compartment or trunk of the car. A geographical analysis of these crime data is presented. Whereas the geo-engineering has focused on improving real-time visualization of position and articulation of navigational instructions, the product engineering as a portable accessory has insufficiently addressed the social implications of vulnerability in a high-crime society, the consequence being a focused acquisitive crime wave. 相似文献

Abstract The new Advanced Placement (AP) human geography course is a wonderful opportunity to ensure the availability of high quality geographic education for high school students. As with any course, in addition to the students' interest and ability, their success is also closely linked to the teachers' preparation. In order to be as well prepared as possible, most AP human geography teachers want and need to know several things in addition to the course content. Questions addressed include how to promote the course, who to promote it to, necessary geographic background for both students and teachers, recommended texts and other resources, how to prepare students for the examination, and how to incorporate the course into the school curriculum. 相似文献

Abstract This article discusses the contents and significance of the industrialization and economic development section of the Advanced Placement human geography course. It also describes how the course outline breaks into four sections the concern of economic geographers with the analysis of the spatial character of economic activity. In summarizing the content of these sections attention is given to links with other course modules and to the use of effective pedagogies for articulating key concepts. 相似文献

Abstract The political geography section of the course offers the opportunity to introduce students to one of the most important ways in which humans have divided up the surface of the Earth for purposes of management and control. By challenging students to consider what lies behind the patterns on political maps, this segment of the course can encourage the development of a critical geographical perspective while enhancing student appreciation of the link between geography and current events. 相似文献

高密度开发城市的交通与土地利用互动关系——以广州为例 总被引:15,自引:4,他引:15
在评述国内外城市交通系统与土地利用互动关系研究的基础上,以广州为案例,利用有关政府部门资料、统计资料和实地调查资料,引入定量分析和GIS、RS空间分析技术,系统全面地研究了我国高密度开发城市交通系统与土地利用互动关系。结果表明:城市交通系统与土地利用之间相互影响、相互作用。交通系统的发展引起城市空间形态、土地利用开发、土地利用价格和用地布局特征的变化;反之,土地利用特征的改变也带来了交通线网格局、交通密度特征及交通模式的改变。 相似文献

“两规”新旧土地利用分类体系比较 总被引:2,自引:0,他引:2
近年来“两规”衔接已成为一个重要的研究课题,“两规”新用地分类体系的先后发布给“两规”衔接带来了契机。运用比较分析方法研究了“两规”新、旧用地分类体系的相互关系,将“两规”用地分类体系的关系演变划分为1997年以前相互独立发展、1997-2006年相互冲突和2006年以来相互衔接3个时期。“两规”旧用地分类体系的比较表明两者在分类重点、分类体系构成、建设用地分类方法和空间范围4个方面的矛盾和冲突最明显。“土规”新、旧用地分类体系的比较表明有4个方面的特征变化:①现状、规划两套分类体系由相互分离转变为相互衔接;②现状分类由三级体系变为二级体系;③在建设用地分类中突出考虑了行业因素;④增强了规划分类的弹性空间。“城规”新、旧用地分类体系的比较分析表明有2个方面的特征变化:①增加城乡用地分类体系;②修订城市建设用地分类体系。最后构建了“两规”新用地分类体系的对应关系。 相似文献

Abstract Vulnerability resulting from debt is part and parcel of the risk society and a salient characteristic of current neoliberal times under financialized global capitalism. Rising indebtedness increases the susceptibility of homeowners to housing and labor market restructuring, and if the degree of leverage is very high, can threaten the solvency, living standards, and social stability of local communities. However, very little is understood regarding how levels of household indebtedness are spatially distributed within or across cities, and how private debt maps onto the geography of race, class, housing, urban form, and other social variables, especially outside of the United States. It remains unknown whether and how higher and unsustainable levels of indebtedness might be associated with urban growth, decline, suburbanization, gentrification, immigration, racialization, and/or greying. This article examines the spatial distribution of household debt in Canadian cities at multiple scales of analysis. It analyzes how levels of household debt relate to a number of key socio-demographic and housing variables from the census, including those related to changes occurring over the 2000s. It simultaneously models the geography of debt at the metropolitan and neighborhood scales using multi-level hierarchical linear modeling methods, and in doing so, it identifies some key drivers and correlates of household debt and the scales at which they operate. The article concludes by discussing the implications of the empirical findings for understanding the role of the emerging urban debtscape in the restructuring of the social geography of the city. 相似文献

城市一直都是多样性集聚的场所,且在全球化、信息化时代背景下日益开放和融合发展,进而呈现出多元化和差异化增强的趋势,功能复合开发是应对上述趋势并提高城市化发展水平的一种普遍选择。本文从中外城市功能复合发展的路径出发,从城市、社区、建筑等多个尺度探讨了城市功能复合的模式与相关规划策略,同时,结合广东省新型城市化发展实践,提出了促进人口多元化、在新区开发中预留白地、旧城改造中引荐棕地、填充式开发理念以及"TOD+SOD+EOD"的综合开发策略,以期为未来进一步优化城市土地利用布局、提高城市空间活力、推进社会多元包容发展探索可能的途径。 相似文献

《The Journal of geography》2012,111(3-4):99-110
Abstract The Advanced Placement human geography course affords high school students the opportunity to experience an introductory college-level course in geography. Population is one of six major themes in the course. The course outline identifies four key areas of study in the population unit: geographical analysis of population, population distribution and composition, population growth and decline over time and space, and population movement. This article addresses each of these areas of study and identifies examples of concepts, topics, and types of data that could form the basis for instructional activities. A resource list is provided for additional reading. 相似文献

济南城市土地利用的圈层结构分析 总被引:5,自引:0,他引:5
利用1986年和2000年两个时相的航空影像进行城市土地利用解译,通过MapInfo、ArcView等GIS软件对矢量化的解译成果进行空间分析与查询统计。研究表明:济南市建成区内的土地利用结构可分为三个圈层,但与传统的圈层模式相比,又具有鲜明的特点。内圈层功能以居住和商业金融服务为主,且居住用地比重偏大;中间圈层土地利用的空间结构比较均衡,随时间变化较平稳;外层土地利用的时空变化明显,工业用地比重较大。 相似文献
