ABSTRACT. Biopolitical use of geosurveillance can create and sustain a politics of fear. Although the majority of surveillance literature focuses on individuals, in this article I focus on groups and populations, drawing on Michel Foucault's analysis of biopolitics. After discussing the forms and history of geosurveillance I argue that three particularly important factors contribute to these politics: divisions, geospatial technologies, and the risk‐based society. In order to combat the negative unintended consequences of these factors I suggest that more attention be paid to the mutual relationships between geospatial technology and politics, rather than on assessments of the value of individual surveillant technologies.

The flight crew on United flight 351 from Atlanta to San Francisco elected to stop in Dallas around 7 a.m., said SFO spokesman Mike McCarron, after finding a backpack on board that no one claimed. The unattended backpack contained a PDA device, McCarron said, “like a Blackberry.” Authorities searched the plane in Dallas and found nothing unusual, he said.—Marisa Lagos, 2006. 相似文献

跨市轨道交通溢价回收策略与多层级管治：以珠三角为例 总被引：1，自引：1，他引：0
随着城市化和机动化的发展,跨市轨道交通建设成为应对交通拥堵,引导土地开发与通勤结构,促进区域一体化的策略。面对轨道交通巨额建设运营成本,多层级政府管治（Multi-level Governance）下的投融资模式和溢价回收（Value Capture）策略成为推动跨市轨道交通建设的基础。目前,对跨市交通设施的溢价回收和多层级管治还缺乏系统讨论。以珠三角为例,实证分析跨市轨道交通多层级政府的合作博弈、投融资模式与溢价回收策略,重点论述由“省部合作”向“省市合作”联合开发的溢价回收策略转变。研究发现,珠三角跨市轨道交通联合开发面临土地、规划和财税等制度约束以及政府间利益博弈,省政府主导的“省市合作”交通土地综合开发模式超越单个城市政府,实现区域层面的交通溢价回收,能为中国城际轨道交通融资和多层级管治提供参考。 相似文献

Using a case study approach, this article explores the potential to increase public transit ridership via the expansion of Unlimited Access (UA) from a university‐ or employer‐based program to a community‐based program. UA partners universities or employers with regional transit organizations to provide free or discounted public transit service to students as well as employees and, potentially, to local community residents. A case study on the only known UA program failure highlights the importance of equitable cost attribution as well as stakeholder coordination and dedicated operations funds to the long‐term success of community‐based UA programs. 相似文献

THE PANOPTICON'S CHANGING GEOGRAPHY 总被引：1，自引：0，他引：1
ABSTRACT. Over the past two centuries, surveillance technology has advanced in three major spurts. In the first instance the surveillance instrument was a specially designed building, Bentham's Panopticon; in the second, a tightly controlled television network, Orwell's Big Brother; today, an electronic human‐tracking service. Functionally, each technology provided total surveillance within the confines of its designated geographical coverage, but costs, geographical coverage, and benefits have changed dramatically through time. In less than a decade, costs have plummeted from hundreds of thousands of dollars per watched person per year for analog surveillance or tens of thousands of dollars for incarceration to mere hundreds of dollars for electronic human‐tracking systems. Simultaneously, benefits to those being watched have increased enormously, so that individual and public resistence are minimized. The end result is a fertile new field of investigation for surveillance studies involving an endless variety of power relationships. Our literal, empirical approach to panopticism has yielded insights that might have been less obvious under the metaphorical approach that has dominated recent scholarly discourse. We conclude that both approaches—literal and metaphorical—are essential to understand what promises to be the greatest instrument of social change arising from the Information Revolution. We urge public and scholarly debate—local, national, and global—on this grand social experiment that has already begun without forethought. 相似文献

Generic action‐thriller films, especially The Bourne Ultimatum, the last in a series of three films, provide a useful resource for examining the gendered nature of geopolitics, the specification of place, and the role of geosurveillance in post‐9/11 national security. Using the dialogue of the film as key source material, I show how the private world of Jason Bourne, an assassin, is interwoven with the public sphere of international security, including covert operations: The personal is geopolitical. I conclude with some reflections on how we might use film as a critical pedagogical resource. 相似文献

ABSTRACTEffective public transit planning needs to address realistic travel demands, which can be illustrated by corridors across major residential areas and activity centers. It is vital to identify public transit corridors that contain the most significant transit travel demand patterns. We propose a two-stage approach to discover primary public transit corridors at high spatio-temporal resolutions using massive real-world smart card and bus trajectory data, which manifest rich transit demand patterns over space and time. The first stage was to reconstruct chained trips for individual passengers using multi-source massive public transit data. In the second stage, a shared-flow clustering algorithm was developed to identify public transit corridors based on reconstructed individual transit trips. The proposed approach was evaluated using transit data collected in Shenzhen, China. Experimental results demonstrated that the proposed approach is a practical tool for extracting time-varying corridors for many potential applications, such as transit planning and management. 相似文献

Increases in biodiversity losses are a growing concern globally. In farm animals, related concerns about losses in genetic diversity have potentially increased with the emergence of breeding technologies that allow for faster genetic change in herds. Farmer and public acceptance of specific breeding practices can be influenced by a number of factors, including concerns about biodiversity and knowledge of biodiversity. The link between these factors and acceptance of new genetic technologies, if it exists, may help explain concerns about genetic technologies. This article examines the effect of attitudes and knowledge about biodiversity on the acceptance of genomic selection in livestock production using farmer and public survey data from Canada. Our results suggest that the link between biodiversity concerns and the acceptance of genomic selection is more robust for the public than for farmers. We also find that biodiversity knowledge and attitudes have opposite effects on acceptance of genomic selection. 相似文献

The development of location-aware technologies, such as smartphones, raises serious questions regarding locational privacy and the ethical use of geographic data. The degree to which these concepts are taught in undergraduate geographic information science (GISci) courses is unknown. A survey of GISci educators shows that issues of privacy and ethics are important in a GISci education. However, a large proportion of GISci educators are not concerned about the loss of locational privacy and many do not devote classes to the subject. Those not teaching the subject cite lack of course time and the need for more information. 相似文献

With an increasing awareness of global climate change, the effect of urban spatial organization, at both city and neighborhood scales, on urban CO2 emission reduction has attracted much scholarly and practical attention. Using Beijing as a case study, this article examines the extent to which neighborhood-scale urban form may contribute to reduction of travel-related CO2 emissions in the context of rapid urbanization and spatial transformation. We derive complete travel-activity records of 1,048 residents from an activity diary survey conducted in 2007. Analysis using structural equation models finds that residents living in a neighborhood with higher land use mix, public transit accessibility, and more pedestrian-friendly street design tend to travel in a “low-carbon” manner and emit less CO2 in daily travel, even controlling for residential and travel preferences. This article offers empirical evidence that sheds light on debates about policy measures to facilitate China’s transition toward sustainable and low-carbon urban development. 相似文献

轨道交通周边土地开发和溢价归公有助于缓解城市财政压力,推动公交都市建设。结合国外实施溢价归公的政策和实践模式,以东莞市为例,在资料收集、政策分析、文本和案例解读的基础上,探讨了中国城市政府在规划和建设轨道交通中,以土地溢价归公反哺轨道交通融资的政策安排和实施效果。结果表明:1)溢价归公的本质是以特定方式实现正外部效应的内部化,由于土地制度和税收体系的差异,欧美地区溢价归公主要依赖多样化的土地税收体系,而中国城市的实践主要借鉴了“轨道+物业”的联合开发模式;2)东莞市溢价归公策略的形成是综合开发规划编制和审批、沿线土地控制和储备、土地发展权转移、土地增值分配等核心环节有效协调的结果;3)东莞轨道交通沿线土地开发能形成可观的财政收益,潜在土地收益占轨道资金总需求的比例超过20%,但在实施过程中仍面临较大困难。东莞市案例能为其他城市轨道交通融资、土地开发和溢价归公的政策体系编制和有效实施提供一定的参考。 相似文献

城市交通、土地利用和城市空间结构的相互关系一直是城市地理学、城市规划学和交通地理学研究的核心问题。大容量公共交通、混合型土地开发、宜人的步行环境和高质量的公交服务是公交导向型开发(TOD)模式的主要特点。本文分析了TOD对城市土地利用和城市空间结构的作用机理发现:土地开发强度、土地利用结构以及土地价值是TOD影响城市土地利用的3 个主要方面,而TOD对路网结构、城市规模和城市空间布局的作用进一步影响城市空间结构及其演化。进一步研究发现:大容量公共交通的建设使得城市竞租曲线和开发密度具有多波峰的特点,遵循"随着时间的变化从城市中心向外围递减"的规律。基于中外城市发展背景差异,本文从宏观、中观和微观3 个层面提出建立以大容量公共交通为主轴、以TOD站点为枢纽的轴辐网络状城市空间结构,并提出了TOD站点开发的距离、级差密度、多样性和设计的4Ds原则。 相似文献

Inadequate transportation has emerged as a major barrier to employment for welfare recipients required to transition from public assistance to employment under welfare reform. Transportation is a particularly daunting barrier for single women without access to a household car. This study uses multivariate techniques to examine whether nearby transit access impacts the employment outcomes of this population in Los Angeles County. Results show that the level of transit service near a recipient's home makes a moderate, yet statistically significant, contribution to increasing the probability of employment and transit use for work-related trips. However, recipients who use public transit face multiple problems, including overcrowding and infrequent service. 相似文献

Accessibility is an important consideration in sustainable mobility policies, particularly for transit users. Measures suggested in the literature are based on coarse aggregate spatial resolution of traffic analysis zones that is sufficient for managing car travels only. To reflect a human door-to-door travel, transit accessibility demands an explicit view of the location of origin, transit stops and destination, as well as of the temporal fit between transit lines timetable and traveler’s needs. We thus estimate transit accessibility based on mode-specific travel times and corresponding paths, including walking and waiting, at the resolution of individual buildings and stops. Car accessibility is estimated at a high resolution too. A novel representation of transit network as a graph is proposed. This representation includes all modal components of a transit travel – walking, waiting at a stop, transit ride, transfers between lines, thus enabling unified view of a travel, regardless of mode. The use of modern high-performance graph database allows construction of high-resolution accessibility maps for an entire metropolitan area with its 100–200 K buildings. The application is tested and applied in a case study involving the evaluation of the 2011 bus line reform in the city of Tel Aviv. Specifically, we demonstrate that while the reform increased the average accessibility for the entire city the increase was not uniform with different areas of the city experiencing different absolute accessibility by transit and relative accessibility in comparison to car travel. The bus reform did in fact benefit travelers that experienced low relative accessibility, but the benefits are mainly accruing to longer trips. Our approach and computational methods can be employed for directly investigating the impacts of transportation infrastructure investments. 相似文献

Norway's regional structure is under debate as questions about territorial boundaries, scale, scope of tasks and responsibilities, and decision-making structures have become an issue in Norwegian politics. This tendency of changing the scale of public action with regard to governmental structures, economic politics, welfare, and civic society has been termed ‘new regionalism’. New regionalism often comes under criticism of being too neo-liberalistic or too economically orientated, leaving in its wake debates of democratic accountability and the neglect of ‘soft factors’ (i.e. socio-culture, identity, consciousness, and participation). In this article the authors investigate whether new democratic or semi-democratic regional organisations as advocated by new regionalist schemes require identification amongst the local population in order to be successful and enduring governmental structures. Further, it is shown how too simplistic understandings of the social processes, and their inherent power aspects, involved in the implementation of the new regionalist development scheme ‘Mountain Region’ distort the undertaking. The authors find that a more complex relational and contextual understanding is in demand, one in which regionalisation is not only recognised as a process which diffuses across time-space, but also takes an asymmetrical place across society's social fabric, and one where ‘soft factors’ such as ‘regional identity’ are not sidestepped. 相似文献

With the explosive growth of Uber and other mobility service providers, their influences on urban mobility have attracted attention from both researchers and policy circles alike, yet few quantitative studies have been conducted on the topic. Using Uber pickup data in New York City in 2014, this article investigates the spatiotemporal relationship between Uber and public transit using buffer analysis and spatial cross-correlation analysis and assesses Uber’s impact on urban transportation equity with the Gini coefficient and correlation analysis. Our results confirm previous arguments that Uber both complements and competes with public transit, but competition is more prevalent in New York City. Specifically, Uber competes with public transit during most hours of the day and in areas with good public transit coverage, whereas it complements public transit at midnight and in places with insufficient public transit services. The distribution of Uber services is highly unequal, and Uber’s role in improving transport equity is insignificant. Correlation analysis shows that there tend to be fewer Uber pickups in low-income areas, which diverges from previous studies suggesting that Uber serves low-income areas well. In addition, a weak negative correlation is detected between the number of Uber pickups and the percentage of minorities. 相似文献

Learning about learning: lessons from public engagement and deliberation on urban river restoration 总被引：1，自引：0，他引：1
JUDITH PETTS 《The Geographical journal》2007,173(4):300-311
This paper provides a new discussion of how people learn through deliberative processes, drawing upon empirical analysis of a novel public engagement process for urban river restoration. Such critical evaluation is rare and yet will be crucial to both theoretical development and learning about engagement practice, not least in a policy area subject to strong regulatory drivers for public participation. The analysis supports two important learning mechanisms – the use of 'gatekeepers' of knowledge, interests and values, and the privileging of narrative. It provides new evidence of instrumental and communicative learning about shared priorities and criteria for effective river restoration that evolved through the deliberative process and directly informed the restoration scheme. It is important to question whether and how such site or context-specific learning might inform other restoration schemes. Finally, the paper questions the often ignored issue of expert learning, not least the issue of the link between individual and organizational learning. 相似文献

基于利益相关者的LUCC生态风险研究——以延河流域为例 总被引：1，自引：0，他引：1
采用生态服务价值的大小代表生态服务功能的强弱,以生态系统服务功能理论为基础,以土地利用/覆被变化导致的生态系统服务功能下降作为LUCC生态风险,分别针对土地利用的各利益相关者——土地的所有者或经营者(个人、社区和国家),定量分析各利益相关者在土地利用/覆被变化的背景下所承受的生态风险。研究表明,由于土地利用/覆被变化的因素,延河流域2000-2006年间生态服务功能总体上升了28.91%,这主要归功于延河流域实施的退耕还林还草措施。对LUCC的不同利益相关者进行分析的结果表明,2000-2006年间,国家、社区和个人的生态服务功能均有所增强,增加值分别为34.71%、33.64%、14.57%;它们所面临的主要生态风险是,个人在本区域获取食物供应的能力下降了5.71%,国家在生物控制方面的能力下降了24.56%。 相似文献

The article offers an institutional-comparative approach to a discussion about national regulation and its local consequences. The industrial regulations formulated after Norwegian independence in 1905 allowed public control of transactions concerning rights to Norwegian waterfalls. Efforts to restructure energy-intensive industry have often encountered local demands for the maintenance of local production. Due to the regulations, companies were forced to negotiate with the state and later also with local authorities. Deregulation of the electricity sector in the early 1990s facilitated a radical restructuring as companies stopped using electricity in local production and instead exported it from the region where it was generated. However, companies are still obliged to make different kinds of compensation to the host locality. The article presents cases of single company towns in Telemark and Nordland counties in Norway. 相似文献
