This paper explores the way in which lived experiences of farmers in the Ord Valley have intersected with representations of the Ord Valley over time. I contrast the development of Stage 1 of the Ord River Irrigation Scheme in the 1960s with a proposal put forward in the late 1990s for greatly expanding the area of irrigated agriculture as Stage 2 of the scheme. I examine the rhetoric employed in planning documents and public media coverage of the first and proposed second stages of the Ord Irrigation Scheme and explore its connections with social identifications of farmers in the Ord Valley since the 1960s. I then argue the value of this approach for understanding the dynamic relationship between the spatial practices and social identifications of farmers and representations of place and land use in public media and planning processes.  相似文献

3维文字注记对于直观表达3维场景中对象的文本信息非常重要,但现有研究大多忽略这一问题,该文主要针对城市环境3维建筑物模型的注记问题,提出一种基于视点位置和方向的动态注记方法。该方法依据3维模型离视点的远近对文字注记位置进行分层处理。在视点远近变换时,选取建筑对象的不同细节层次模型作为文字注记的计算对象。进而依据视点的方向实时计算文字注记的方向,达到动态的注记效果。这种动态的注记方法可以避免因视点变换而产生的注记与3维模型之间的遮挡关系,也可以避免场景因注记过多而产生的杂乱情形。实验表明,该方法具有较好的可视化效果。  相似文献

ABSTRACT

Recent 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

The spatial hierarchy of part-whole relationships is an essential characteristic of the platial world. Constructing spatial hierarchies of places is valuable in association analysis and qualitative spatial reasoning. The emergence of large amounts of geotagged user-generated content provides strong support for modelling places. However, the vague nature of places and the complex spatial relationships among places make it intractable to understand and represent the hierarchies among places. In this paper, we introduce a fuzzy formal concept analysis-based approach to uncovering the spatial hierarchies among vague places. Each place is represented as a concept that consists of its extent and its intent. Based on the place concepts, the spatial hierarchies are generated and expressed as a graph that is easy to comprehend and contains abundant information on spatial relations. We also demonstrate the rationality of our result by comparing it with the result of a questionnaire survey.  相似文献

Sheinkin is an example of a place constituted by global forces. Yet Sheinkin creatively responds to scalar jumps of global forces, drawing from the capitals of the global system like Soho and Greenwich village. These models are embedded in the Israeli reality with Sheinkin becoming an incubator of post-Zionist identity. Young people from all over Israel concentrate in the place on Fridays to participate in choreography of strolling along the street with its’ designers’ shops, mingling with celebrities and others who belong to the cult and around the ‘Hyde Park’ corner in which environmental, spiritual and other worldviews are promoted. The article suggests a model to investigate such places as the organic integration of a community whose participants do not live in the place but pilgrimage to the place, a landscape that appraises creativity, originality and individualism, a choreography of strollers who search for stimulations and a set of norms and values promote in the place.  相似文献

In this paper it is argued that even though communication technologies release distance students considerably from their dependency on a campus, students are still very much connected to places in their daily lives. These connections are constituted through the “placing” of technology, the students’ relations to people in their daily lives and the students’ relations to the education institution. Communication technology not only releases students from the spatial dimensions; it also attaches them to specific places. It is argued that the use of technology in distance education can reduce the students’ flexibility even if they do not have to attend campus regularly. The empirical analysis presented in this paper is based on a case study of a Master’s degree programme in Public Management offered by Open University Indonesia (Universitas Terbuka).  相似文献

Research into exposure to, and experience of, environmental risk that has an explicitly spatial focus can be broadly differentiated into two strands. The first strand focuses on the responses of communities of exposure (or the threat of exposure) to some form of environmental hazard and to the policies put in place by institutional actors to manage the hazard. The second strand addresses social inequalities in exposure to environmental hazards and seeks to correlate uneven spatial distributions of risk across different social groups. It is argued that both strands are limited by their respective understandings of space - and that the way in which vulnerable communities experience environmental risk and its management will be shaped significantly by the complex interactions of different spatialisations or constructions of space. We explore this process by examining accounts of local experience of the UK’s 2001 foot and mouth disease crisis and its management in terms of the interplay of two different spatialisations: socio-cultural marginality and political-economic peripherality. We trace the relationship between these cultural and political-economic spatialisations through an analysis of the discursive mobilisation of contrasting place rhetorics. We conclude that focusing on these rhetorics can enhance our understanding of the spatial processes which are constitutive of place identity and in turn mediate the experience of environmental risk and its management.  相似文献
