Remus Creţan 《Urban geography》2019,40(6):805-825
ABSTRACTRecent scholarship in critical toponymy has raised questions about the impacts on urban residents of selling naming rights and the possibility of contesting the commodification of urban place names. This article examines these issues using Poli Timi?oara, the major football team of Timi?oara, Romania, as a case study. The cash-strapped local authority sold the naming rights for the team to raise revenue. However, when the club’s private owner was unable to finance the team, the local authority reacquired the naming rights of Poli, now under the name Asocia?ia Club Sportiv Poli (a new team with a small fan base). Drawing on the everyday narratives of fans, this article explores how the commodification of a local club name can cause social tensions. This is important for understanding urban residents’ access, or lack thereof, to social capital resources and how this leads to the manifestation of social inequalities which co-determine fans’ reactions and responses to the change in the name of a sports team. The findings suggest that commodifying names can mobilize serious contestations among partisan groups about who owns the name, although such contestations appear to be on uncertain ground because of post-communist urban practices of delayed economic restructuring. 相似文献

Although the fast development of OGC (Open Geospatial Consortium) WFS (Web Feature Service) technologies has undoubtedly improved the sharing and synchronization of feature-level geospatial information across diverse resources, literature shows that there are still apparent limitations in the current implementation of OGC WFSs. Currently, the implementation of OGC WFSs only emphasizes syntactic data interoperability via standard interfaces and cannot resolve semantic heterogeneity problems in geospatial data sharing. To help emergency responders and disaster managers find new ways of efficiently searching for needed geospatial information at the feature level, this paper aims to propose a framework for automatic search of geospatial features using Geospatial Semantic Web technologies and natural language interfaces. We focus on two major tasks: (1) intelligent geospatial feature retrieval using Geospatial Semantic Web technologies; (2) a natural language interface to a geospatial knowledge base and web feature services over the Semantic Web. Based on the proposed framework we implemented a prototype. Results show that it is practical to directly discover desirable geospatial features from multiple semantically heterogeneous sources using Geospatial Semantic Web technologies and natural language interfaces. 相似文献

Dynamic chaining of geographic information services (geo-services) is gaining popularity as a new paradigm for evolving flexible geo-information systems and for providing on-demand access to geo-information. In dynamic chaining, disparate geo-services are discovered and composed at run time to yield more elaborate functionality and create value-added geo-information. Common approaches to service chaining discover and compose disparate geo-services based on the functional capability of individual geo-services. The primary concern of common approaches is thus the emergent behavior of the resulting composite geo-service. However, as geo-services become mundane and take on a greater and more strategic role in mission critical processes, deliverable quality of service (QoS) becomes an important concern. QoS concerns operational characteristics of a service that determine its utility in an application context. To address pertinent QoS requirements, a new approach to service chaining becomes necessary. In this paper we propose a QoS-aware chaining approach in which geo-services are discovered, composed and executed considering both functional and QoS requirements. We prescribe a QoS management framework that defines fundamental principles, concepts and mechanisms which can be applied to evolve an effective distributed computing platform for QoS-aware chaining of geo-services – the so-called geo-service infrastructure. The paper also defines an extensible QoS model for services delivered by dynamic compositions of geo-services. The process of orthophoto generation is used to demonstrate the applicability of the prescribed framework to service-oriented geographic information processing. 相似文献

广州市商业型健身房空间分布及其影响因素 总被引:1,自引:0,他引:1
以百度地图网页上采集的POI数据和第六次人口普查数据为基础,借助ArcGIS 10.2和Geoda软件,通过核密度分析、方向分布分析、缓冲区分析、近邻分析和空间自相关等方法,对广州市商业型健身房的空间分布特征进行研究,结果表明:广州市商业型健身房在空间分布上呈现“中心圈层+外围组团”结构,存在空间集聚现象以及沿城市干道和地铁站分布指向性不明显而呈现临近住宅小区分布指向性。在广州市商业型健身房空间分布的影响因素方面,经过模型比较,选择空间滞后模型对其进行定量分析,结果表明:人口规模与受教育水平对广州市商业型健身房的空间布局影响显著,而区位因素和社区环境影响力较小。 相似文献
