Localized Effects of Globalization: The Case of Ciudad Juárez,Chihuahua, Mexico

This paper explores how the rise of global industrialization has altered the internal complexion of Ciudad Juárez, Chihuahua, the largest and fastest growing of Mexico's northern border cities. First, we trace the political-economic history of Ciudad Juárez and other northern Mexican border cities in order to understand the context of rapid industrialization. Second, we document the dimensions of industrialization by tracing historic trends in population growth, industrial employment, and land-use change. Third, a deprivation index is developed to evaluate the effects of industrialization on quality-of-life at the neighborhood scale in Ciudad Juárez. Deprivation indices are calculated for 266 AGEBs (Mexican geostatistical districts) for the years 1990 and 1995, and changes in levels of deprivation are monitored over time. The analyses show that Ciudad Juárez has experienced unprecedented growth that altered the form, function, and social complexion of the city.     

中国主要沿海城市旅游竞争力定量研究

基②国内外对城市旅游竞争力研究的回顾和梳理,建立契合本研究的指标体系：以城市旅游基础设施、发展现状和生态环境竞争力作为二级指标,以25个与城市旅游竞争力相关指标作为三级指标。在此基础上,利用主成分分析与系统聚类分析方法测算各城市因子得分及排名,并对城市间、等级间、区域间优势和劣势做出比较分析。结果表明：①上海、杭州、广州旅游竞争力相对较强,南通、中山、东莞竞争力相对较弱,其中,城市经济体规模、环境污染程度及城市绿化水平对城市旅游综合竞争力影响较突出;②城市间旅游竞争力水平梯度化明显,抱团式合作发展、阶梯状搭配发展前景看好;③同一区域内城市合作优势大②竞争优势,可建立旅游合作试点区域。     

关于世界城市研究的两场争论及其对相关研究的影响

20世纪80年代以来",世界城市"成为城市研究领域的热点话题。在迄今30年的研究过程中,2000年前后发生的针对世界城市经典理论的两场学术争论具有里程碑意义:①关于世界城市发展动力和类型的争论;②关于世界城市发展历史的争论。通过争论,凝聚了学界共识,引发了本研究领域逐步从论证经济全球化对城市重构的作用转向讨论城市全球化的多样路径。两场争论之后,"世界城市政治"和"世界城市历史"的讨论成为新世纪两个重要的研究方向。本文回顾了经典世界城市理论以及对其的早期批评,详细介绍了两场争论及其引发的两种研究方向,并在此基础上提出了对中国世界城市研究的启示。     

The impact of planning on pedestrian movement: contrasting pedestrian movement models in pre-modern and modern neighborhoods in Israel

Most pedestrian movement volume models were constructed for urban areas that developed on the basis of pre-modern planning. In this paper, we confront neighborhoods that were built upon modern planning doctrines, combining the functional hierarchy of streets with the neighborhood unit concept, with neighborhoods that developed from pre-modem non-hierarchical street-based planning. We use space syntax analysis to investigate how their street network’s structural attributes interact with pedestrian movement distribution. The investigation was conducted in 14 neighborhoods from 4 cities in Israel by examining the correlation of observed pedestrian volume with models using different axial- and segment-based topological, angular, and metric syntactic attributes across different radii (scales). The results indicate that the street network and the distribution of pedestrian movement interact differently in the two neighborhood types. In pre-modern neighborhoods: (i) there is significantly more walking; (ii) the street network’s syntactic attributes tend to be much more consistent in their correlation with pedestrian volume across all scales; (iii) the correlation of pedestrian volume with these attributes and with commerce is relatively high; and (iv) pedestrian movement distribution is more predictable. We relate these differences to the absence of a self-organized circular causality between street network structure, commerce, and movement in modern planned neighborhoods.     

TEMPORAL AND SPATIAL DIMENSIONS OF NEWLY INCORPORATED MUNICIPALITIES IN THE UNITED STATES*

Scholarly literature on newly incorporated municipalities (nims ) often focuses on why nims form. Instead of asking why nims formed, however, we ask why nims stopped forming. We first establish a temporal context for nims from 1950 to 2010, revealing an 86.2 percent decline in nim formation. The decline, triggered by stricter laws, smaller annexations, declining suburbanization, and boundary ossification, has profound implications for metropolitan fragmentation and public choice. We then establish a state‐level spatial context, revealing distinct high‐nim , low‐nim , and flux states due to boundary ossification, growth, and state/regional policy stimuli such as consolidation efforts, grants, and growth management provisions.     

Beyond the Metropolis: Urban Geography as if Small Cities Mattered

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.     

A Review of “Urban Climate Change Crossroads”

This article examines the former location-based social medium Brightkite, over its three-year life span, based on the concept of natural cities. The term natural cities refers to spatially clustered geographic events, such as the agglomerated patches aggregated from individual social media users’ locations. We applied the head/tail division rule to derive natural cities, based on the fact that there are far more low-density areas than high-density areas on the Earth's surface. More specifically, we generated a triangulated irregular network, made up of individual unique user locations, and then categorized small triangles (smaller than an average) as natural cities for the United States (mainland) on a monthly basis. The concept of natural cities provides a powerful means to develop new insights into the evolution of real cities, because there are virtually no data available to track the history of cities across their entire life spans and at very fine spatial and temporal scales. Therefore, natural cities can act as a good proxy of real cities, in the sense of understanding underlying interactions, at a global level, rather than of predicting cities, at an individual level. Apart from the data produced and the contributed methods, we established new insights into the structure and dynamics of natural cities; for example, the idea that natural cities evolve in nonlinear manners at both spatial and temporal dimensions.

中国中心城市公路客运联系及其空间格局

依托中国地级中心城市间的公路长途客运联系数据,运用GIS空间网络分析方法,对中国公路客运联系网络结构及其分布格局进行清晰的空间解构。研究显示：公路客运联系强弱与城市人口规模和经济总量相关性较强,而与经济发展水平不相关性;中国人口经济密集分布的东中部地区中心城市间的公路客运联系密切,呈现区域性集聚的分布格局;最为密集的区域为长三角、珠三角两地,而京津冀、山东省、河南省和成渝地区的集聚程度也相对突出。总体上,中国公路客运联系以各省份的省会及区域中心城市为联系中心,以区内其他城市为联系对象,在中短途客运距离内形成自成一体的区域性空间集聚。研究表明：中国公路长途客运联系的适宜空间距离应在500 km以内,最佳客运距离为100~300 km左右;中国公路长途客运联系在200 km内是随着距离增大而增加,之后则呈现二次曲线型的距离衰减趋势;细分各距离区段内的公路客运联系可以清晰识别城市群内、省域内、省际间及大区域间等不同空间尺度下区域交通联系的结构特征。     

基于高铁网络的中国省会城市经济可达性

基于列车时刻表中的省会城市间交通时间以及相应票价数据和各省市城镇居民家庭人均收入数据,以铁路服务价格、城镇居民消费铁路服务能力两方面为突破口,分析高铁网络对中国省会城市经济可达性的影响。结果表明：① 高铁网络不同程度地提升了省会城市铁路服务价格,降低了铁路服务价格与时间可达性的相关性,同时改变了铁路服务价格的分布格局。② 城镇居民消费铁路服务能力等级差异明显,其中收入水平发挥着决定性作用,而铁路服务价格的影响也不容忽视。③ 高铁网络缩小了“所有城市”铁路服务价格、铁路服务消费能力分布的不公平性,但扩大了“高铁城市”铁路服务价格、铁路服务消费能力分布的不公平性;铁路服务消费能力分布的不公平程度高于铁路服务价格分布的不公平程度。
