Abstract Historians of telegraphy have traditionally focused on the system-builders who invented wire communications technologies and incorporated them into profit-making enterprises. Geographers of communications have traditionally traced the changes that the telegraph network wrought on the rank-size of cities and the speed of business. Both have ignored the history of the telegraph messenger boys and the “lived geography” of the telegraph network. This article summarizes a study of telegraph messengers as both active components of technological systems and laboring agents within produced urban spaces, bringing together the fields of both history of technology and human geography. 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

This article investigated the pedagogical potential of the SimCity simulation game in an urban geography course. University students used SimCity to build their own cities and applied a wide range of theories to support their urban structures. Moreover, the students critically evaluated the logic and functioning of the SimCity simulation compared to real-world contexts and urban geography principles. The students believed the SimCity activity provided them with opportunities to promote their geographic creativity, resulting in diverse, unique, and interesting cities. The findings demonstrate that the use of SimCity can be an effective tool for geography education. 相似文献

Mounting evidence indicates that large, world-class cities have expanded their spatial markets well beyond the regional urban systems in which they are located. This has led many observers to conclude that in the contemporary economy, interdependence, interaction, and connectivity are no longer fundamental characteristics of hierarchical urban systems. Virtually all research, however, deals exclusively with the changing role of large cities, while the spatial markets of medium- and smaller-sized cities comprising an urban system have been ignored. The primary objective of this paper is to investigate whether the spatial markets of medium- and smaller-sized cities in an urban hierarchical system continue to display a systematic relationship with city size, or whether they also reveal the absence of connection, or integration, with the regional system. The analysis uses survey data collected from 480 producer service firms located in an urban hierarchy comprising 15 midwestern cities of the United States. The results indicate that the spatial market of the largest city (Chicago) extends well beyond the Midwest urban hierarchy, while the spatial markets of smaller-sized cities are more integrated within the hierarchical system. 相似文献

ABSTRACTThis paper is a broad review of green infrastructure theory and practice relative to urban sustainability and the space for geographers in these discussions. We use examples from various urban sustainability plans to highlight ways in which green infrastructure is being conceptualized and implemented. We explore how geography contributes research on green infrastructure as well as the emerging practices as seen within sustainability plans. We identify four areas in which geographers can influence both green infrastructure theory and practice: 1) scale; 2) mapping distribution; 3) sensitivity to place and locale; and 4) equity and access. We conclude that in these areas geographers have tremendous opportunity contribute more deliberately to sustainable urbanism. 相似文献

ABSTRACT Urban greening is about bringing vegetation into cities in ways that produce flourishing urban ecologies whilst also making cities more liveable for human inhabitants. We focus here on greening that is done through the maintenance or establishment of gardens, parks, urban forests and informal spaces. We argue that in contexts with established property law systems, such as Australia, making urban ecologies through greening is shaped heavily by relations of property tied to land. This includes constraining the extent to which urban greening can contribute to socio-ecologically just cities. We suggest that progressing greening that is more attentive to the geographies and temporalities of more-than-human life requires us to trouble the hold of property over greening. To do this we explore the possibilities opened up by the lens of urban commons/commoning. We engage with the emerging concept of more-than-human commoning as a way of attuning urban greening to nonhuman agency and affordances. We also grapple with the risk of obscuring or concealing difference between humans in the way commoning makes room for more-than-humans, especially in the context of settler-colonialism. We conclude by calling for a more overt politics of urban greening that encompasses diverse human and more-than-human experiences of the city. 相似文献

Recent anti-systemic social movements have illustrated the central role of cities in social movement mobilization. We not only highlight the characteristics of urban social relations that make cities fertile ground for mobilization, but also point to the disjunctures between the geographies and spatialities of social relations in the city, and the geographies and spatialities of many systemic processes. Struggles for a more just society must consider the broad geographies and spatialities of oppression, which we illustrate with a brief analysis of the Occupy movement. Finally, we introduce the next five articles in this special issue, all illustrating the importance of the geographies and spatialities of urban social struggle. 相似文献

ABSTRACTThough global-coverage urban perception datasets have been recently created using machine learning, their efficacy in accurately assessing local urban perceptions for other countries and regions remains a problem. Here we describe a human-machine adversarial scoring framework using a methodology that incorporates deep learning and iterative feedback with recommendation scores, which allows for the rapid and cost-effective assessment of the local urban perceptions for Chinese cities. Using the state-of-the-art Fully Convolutional Network (FCN) and Random Forest (RF) algorithms, the proposed method provides perception estimations with errors less than 10%. The driving factor analysis from both the visual and urban functional aspects demonstrated its feasibility in facilitating local urban perception derivations. With high-throughput and high-accuracy scorings, the proposed human-machine adversarial framework offers an affordable and rapid solution for urban planners and researchers to conduct local urban perception assessments. 相似文献

Abstract Current regionalizations of Africa have limitations in that they are attribute-based and regions are delineated according to national boundaries. Taking the world city network approach as starting point, it is possible to use relational data (i.e., information about the relationships between cities) rather than attribute data, and moreover, it becomes possible to ignore state boundaries by delineating the regions based on the location of the interaction structure between cities. This research uses airline data. A network analysis is performed on the number of passengers who fly between cities in Africa. A subregional map is created based on the results. 相似文献

Abstract Experiential learning pedagogies are being adopted across undergraduate education and touted as an effective strategy for enhancing student learning. This paper develops an explanation for how and why such pedagogies can foster students' critical thinking and learning. Drawing on data collected from first-year students in “field based” urban geography courses at an urban university, I show how students' existing knowledge of urban spaces and specific parts of the city is constructed from a variety of sources and experiences, and can be incorporated in experiential learning activities in ways that foster critical learning. Such an approach is crucial to creating learning environments in higher education that include a greater diversity of student identities and life experiences. 相似文献

Abstract This article presents a lesson plan used to teach about African urbanization using Kenyan novels. Specifically, three urban novels written by Meja Mwangi are used. Based on a qualitative survey of student preference and learning, this lesson plan uses these novels alongside more traditional academic texts to achieve effective student learning. Understanding that students prefer to read novels but learn best from textbooks, this mixture of texts generates emotional discussions that are substantiated with factual research. 相似文献

中国东北地区城市地理基本框架 总被引：18，自引：0，他引：18
从东北地区城市地理框架的形成和演变过程出发,对东北地区城市体系框架、中心城市和大都市区、城市群和城市组群等城市地理问题进行了研究。结果表明,东北地区城市地理框架的形成演变过程分为三个时期,即古代城镇形成时期-近代城市形成时期-现代城镇体系形成发展时期。将城市体系结构框架归纳为：自上而下先快后缓的城市化进程,“弱金字塔”型的等级规模结构,沿铁路分布的“T”型空间结构,由“单一”向“新型”发展的城市职能结构。东北地区以哈尔滨、长春、沈阳、大连为中心城市的“四城市时代”已经到来,三省GDP向四城市高度集中,并且依托四市正在形成发展为“大哈尔滨”、“大长春”、“沈阳经济区”和“大大连”四个大都市区。作为城市化发展到一定阶段的产物,东北地区的城市群和城市组群也发育得相对完备而密集,已初步形成“三圈”的基本格局,即辽中南城市群以及吉中、哈大齐等2个大型城市组群。 相似文献

Abstract Successful curriculum development that will have impact upon individual American classrooms remains the key to maintaining the momentum of Geography for Life: National Geography Standards 1994. Teachers and students must be able to translate the national geography standards from the national stage to the local classroom setting to become geographically informed people. One example of this development for elementary urban geography is the Main Street lesson plan. It encourages observation and analysis required by Standard 4: The geographically informed student knows and understands the physical and human characteristics of places. After testing in a variety of Missouri classrooms, instructors thought that Main Street was a unique way of studying urban places and allowing students to gain a greater understanding of place. 相似文献

AbstractUrban growth is a significant trend in Africa. Scholarly attention and urban planning efforts have focused disproportionately on the challenges of big cities, while small and medium-sized urban settlements are growing most rapidly and house the majority of urban residents. Small towns have received some attention, but very few studies have focused on secondary cities. This paper offers a study of urban transformations, migration and residential mobility patterns in Arusha, a rapidly growing secondary city of Tanzania. Arusha functions as a major attraction for migrants and in-migration is a central dynamic shaping transformation processes in central areas characterized by high population turnovers, vibrant rental markets and widespread landlordism. There is also a considerable degree of intra-urban residential mobility within and between central areas. Intra-urban residential mobility is the most important dynamic shaping transformation processes in peripheral areas characterized by long-term urban residents moving from central parts of the city as part of a process of establishing themselves as homeowners. Overall, the paper provides crucial insights on how migration and residential mobility patterns influence processes of urban growth and transformation in the context of large secondary city, and thereby contributes to fill a significant knowledge gap on secondary cities in Africa. 相似文献

城市标度律及应用 总被引：2，自引：0，他引：2
城市标度律刻画了城市系统某一指标和人口规模的幂函数缩放关系,包括超线性（社会交互类指标）、次线性（基础设施类指标）和线性（个人需求类指标）3种标度关系。本文从城市标度律的验证、解释、应用和质疑4个方面总结梳理了2007—2020年间的研究进展,重点分析了城市标度律和城市时序发展的异速增长律的明显差异,单个城市时序发展不会遵循城市系统的截面标度律。城市规模修正指标为更加客观地评价城市表现提供了新思路。考虑城市规模效应后,2017年中国经济产出效率较高的城市主要位于东南沿海、长江中游和新疆,而东北和中原地区城市经济产出效率较低。城市标度律的机制解释、城市系统动态演化模型和城市内部标度律是未来值得关注的研究方向。 相似文献

AbstractThe use of SWOT analysis is a means through which geography students can investigate key concepts in economic geography and essential topics in regional economic development. This article discusses the results of a course project where economic geography students employed SWOT analysis to explore medium-sized metropolitan areas across the southern United States and their suitability for export-led development. The results suggest that students were able to critically evaluate these urban regions and their potential for integration into the global economy. This case also intimates that the SWOT concept could be applied to other situations and regions in geography coursework. 相似文献
