RSS新闻事件的多维描述与时空可视化方法     

桑鹏  唐新明  艾波  王华斌 《地球信息科学学报》2014,(3):341-348

百度等按照时间或焦点的传统新闻检索方式,缺少对新闻事件在时间维度和空间维度及时空发展规律上的组织和表达。鉴此,本文提出了一种在时间和空间维度对在线简易信息聚合(Really Simple Syndication,RSS)新闻进行多维描述和时空可视化的方法,帮助用户全面、直观理解焦点新闻事件的时空发展过程及趋势。该方法从新浪、百度和Google等多家网站的RSS新闻服务中抽取新闻,将新闻报道时间近似为新闻事件发生时间进行时间维度描述,动态解析并识别新闻概要中的中文地名词汇,进行地址匹配和空间定位,完成新闻事件空间维度描述。以H7N9禽流感热点新闻为例,本文通过过度颜色、统计折线图进行时间维可视化表达,以大小渐变的圆形符号进行空间维可视化表达,多维度描述并展示了H7N9禽流感新闻事件的发展过程和趋势。  相似文献

Marketing the Chinese Dream Home: Gated Communities and Representations of the Good Life in (Post-)Socialist Shanghai     

《Urban geography》2013,34(2):129-159

This paper examines the advertising themes and rhetoric that have been assembled in the place-marketing of Shanghai's newly built gated communities. We demonstrate how place-marketing strategies, in this case selling the Chinese dream home, draws upon specific landscape meanings and values that are embedded in Chinese/Shanghainese history, even as symbolic and cultural capital from the contemporary scene also exert their influences. Collectively, these representations of the good life both reflect and reinforce the exclusivist housing aspirations and privatist visions of middle-class residents of gated communities in contemporary Shanghai. While advertisements do not always achieve the outcomes that property developers wish for, there is no doubt that they play significant roles in both shaping and reflecting landscape meanings and values. As medium and outcome, they reveal the growing aspirations of a new Chinese middle class.  相似文献   

Imagining the Dirty Green City     

Wendy Steele  Aidan Davison  Aviva Reed 《The Australian geographer》2020,51(2):239-256

ABSTRACT

The green city is being elevated to the status of a self-evident good in the theory and practice of urban sustainability. A large literature documents the linked environmental, economic and well-being benefits associated with vegetating urban systems to maximise the ecosystem function. Contemporary urban greening seeks to challenge attempts to expel nature from the city in a quest for order and control. However, by imagining nature as a new mode of urban purification, much effort in the name of the green city inverts and reproduces dualistic understandings of natural and built space. In response, we disrupt the normative dialectics of purity and dirt that sustain this dualism to expose the untidy but fertile ground of the green city. We draw together Ash Amin’s four registers of the Good City – relatedness, rights, repair and re-enchantment – with the artworks of the Australian visual ecologist Aviva Reed. Our work seeks to enrich the practice of more-than-human urbanism through ‘dirt thinking’ by imagining the transformative possibilities in, of and for the dirty green city.  相似文献   

Towards good governance of urban greening: insights from four initiatives in Melbourne,Australia

ABSTRACT

Urban greening can enhance sustainability and liveability, through conserving biodiversity, mitigating urban heat and enhancing people’s health and wellbeing. However, urban greening is complex, as it occurs in unique ecological settings, with social, cultural and economic factors shaping the forms it takes. This raises questions about the governance of urban greening, including what counts as ‘good governance’. In this paper, we first outline principles of good governance drawn from the natural resource management context. We then present four urban greening initiatives from Melbourne Australia representing different scales, land tenures and organising structures. Following this, we analyse how governance of the four initiatives addresses good governance principles. Our analysis shows that there are diverse ways in which urban greening can be practiced and governed. The importance of more ‘informal’ initiatives should not be discounted relative to formalised initiatives, as a spectrum of approaches can be seen as strength. Further, in determining what constitutes good governance, the standards against which initiatives are assessed should be tailored to their specific circumstances, and consider impacts to the environment itself. These findings point to good urban greening governance being both situated and principled.  相似文献

Assessing participatory GIS for community-based natural resource management: claiming community forests in Cameroon   总被引：6，自引：1，他引：6  

MICHAEL K McCALL  PETER A MINANG 《The Geographical journal》2005,171(4):340-356

This paper critically reviews and analyses participatory GIS (PGIS) and participatory mapping applications within participatory spatial planning for community-based natural resource management in developing countries. There is an often implicit assumption that PGIS use is effective, in that it meets content needs, satisfies underlying local stakeholder interests and therefore is a tool for better governance. The analytical framework looks at participatory spatial planning performance with respect to key dimensions of governance, especially the intensity of community participation and empowerment, equity within communities and between 'governed' and 'governing', respect for indigenous knowledge, rights, ownership, legitimacy, and effectiveness. Specific development focus is given by a case study using participatory mapping and PGIS in community forest legitimization, planning and management in Tinto, Cameroon. 'Good governance' criteria are applied ex-post to the implementation procedures, the geo-information outputs, and the longer-term outcomes of the PGIS processes. Impacts of incorporating PGIS were examined in terms of the types and degrees of participation in the process; access to, and the uses made of, the geographic information; whether the information outputs met stakeholders' requirements; and the overall changes in equity and empowerment in the community. It was found that PGIS/participatory mapping processes contributed – positively, though not comprehensively – to good governance, by improving dialogue, redistributing resource access and control rights – though not always equitably – legitimizing and using local knowledge, exposing local stakeholders to geospatial analysis, and creating some actor empowerment through training. PGIS promoted empowerment by supporting community members' participation in decision-making and actions, and by enabling land use planning decisions beyond community forestry itself.  相似文献   

“I…don’t want to see you flashing your bits around”: Exhibitionism,othering and good motherhood in perceptions of public breastfeeding     

《Geoforum》2016

Stigma and concern about public breastfeeding have been identified as contributing towards low breastfeeding rates in high-income countries. Despite this, very little research has examined public perceptions of breastfeeding. Among existing studies, lack of familiarity with breastfeeding, sexist views and hyper-sexualisation of the breast were identified alongside discomfort at viewing breastfeeding by strangers. During 2014, in the United Kingdom (UK), several cases of women being criticised for breastfeeding in public appeared in national newspapers. A Critical Discourse Analysis approach was used to theoretically frame analysis of 884 naturally occurring comments relating to a protest supporting women’s right to breastfeed in public from the UK’s most popular online news site, Mail Online. Findings are discussed in relation to mothers’ roles as citizens and sexual beings, with a particular focus on the visibility of breasts in public space. Women who breastfeed in public were viewed as unattractive, lazy, bad parents and lacking in self-respect. More specifically, women who breastfed in public were viewed as exhibitionist. This was contrasted with the desirability of breastfeeding within the home, which was seen as an appropriate way to feed an infant. The undesirability of public breastfeeding was inherently linked to sexuality, with breastfeeding women viewed as sexual aggressors (“flashers”) or inviting sexual contact from men. It is argued that these views originate in unequal gender relationships in society and the framing of breasts as sexual rather than nurturing. These discourses are played out in public space in which mothers are marginalised in a patriarchal society.  相似文献
