Agents of Eviction: The Squatter Control and Clearance Division of Hong Kong's Housing Department     

Alan Smart 《Singapore journal of tropical geography》2002,23(3):333-347

More is known about the policies that produce forced evictions and their consequences than about the agencies whose responsibility it is to conduct them. Understanding the nature of forced evictions requires greater comprehension of responsible agencies since the ways in which they implement policies may be a crucial intervening variable influencing the outcomes. In this paper, I use documentary and ethnographic research to describe the Squatter Control and Clearance Division of the Hong Kong Housing Department. Responsible both for evicting squatters and for controlling squatter areas that are permitted to remain for the time being, officers must respond to the conflicts and challenges of their twin, partially conflicting, mandates. Examination of changes in squatter control and clearance practices since 1954 is followed by a brief case study of the most recent squatter clearance that occurred in July 2001.  相似文献   

Placing geographies of public health   总被引：6，自引：0，他引：6  

Tim Brown  & Craig Duncan 《Area》2002,34(4):361-369

Following the move to a 'post–medical' geography, a large amount of research has come to focus on public health issues. This paper explores these current geographies of public health and argues for the development of a more critical perspective. In particular, it draws on commentary that has emerged out of debates that have taken place within a body of literature usually identified as the critical 'new' public health. The paper goes on to argue that such scholarship offers crucial insights for the production of a critical geography of public health.  相似文献   

Public environmental information: understanding requirements and patterns of likely public use     

Mordechai Haklay 《Area》2002,34(1):17-28

Public access to environmental information received much attention in the last decade. Recent developments promote access to this information through public telecommunication networks. This paper describes a Web-based survey that explored the requirements and needs of likely users of public environmental information systems for London: educated middle-class members of the public, with high interest in environmental issues and computer literacy. The survey demonstrated current information consumption patterns and the reasons to gather and use such information.  相似文献

中国环境影响评价中公众参与的有效性有待提高   总被引：3，自引：1，他引：3  

刘衍君  吴仁海 《云南地理环境研究》2003,15(3):28-32

环境影响评价(EIA)作为协调经济发展与环境保护的手段，已日益成为国家环境管理的重要工具。公众参与是环境影响评价的重要组成部分。从公众参与的概念及作用出发，分析中国环境影响评价中公众参与的机制，认为存在着参与对象选取不合理、参与形式双向性差、调查内容设置不科学、意见整理分析方法不完善及公众参与时段滞后等影响公众参与有效性提高的问题，最后提出注重参与对象的代表性，形式的有效性，内容的科学性，分析的定量化以及权利的保障等，以提高中国环评公众参与的有效性。  相似文献

The ins and outs of skateboarding and transgression in public space in Newcastle,Australia     

Nicholas Nolan 《The Australian geographer》2003,34(3):311-327

This study examines skateboarding as a transgressive activity in different inner Newcastle public spaces, highlighting the way certain places are constructed, and the values and meanings attached to them. Skateboarding has been sanctioned in some places, but is considered to be inappropriate in others, resulting in the implementation of skating restrictions in specific areas. Transgressive conduct is different from the norm and appears to be ‘out of place’. However, labels of ‘in’ and ‘out’ of place are too simplistic, because transgression is more nuanced and can simultaneously operate at multiple scales. Some skateboarding activities and locations are seen as more legitimate than others, and so a skater can be both ‘in place’ and ‘out of place’ at the same time. Problems and inconsistencies in the regulation of public space are revealed, because although skateboarding may be illegal in some places, the regulations are blunted by limited enforcement, justified by distinctions between ‘good’ and ‘bad’ skateboarding.  相似文献

卫星云图、雷达回波在人工增雨时机选择中的应用   总被引：7，自引：2，他引：7       下载免费PDF全文

张晰莹  金风岭 《气象》2003,29(8):52-54

概述了干旱期间选择飞机和高炮人工增雨作业时机的方法，以2000年6～7月哈尔滨地区特大干旱期间进行的飞机和高炮人工增雨作业为例，利用卫星云图和雷达回波资料选择的作业时间和作业区域应是比较有利的。因为从卫星云图中的水汽图、红外和可见光云图上可分析出云系中的含水量、云顶温度、云系强度，在此基础上利用天气雷达跟踪订正，可直接指挥飞机和高炮在有利的区域和时间内进行作业，获得了明显的效果。  相似文献   

Public participation in monitoring programmes as a tool for lakeshore monitoring: the example of Lake Pyhäjärvi, Karelia, Eastern Finland     

Ritta Niinioja  Anna-Liisa Holopainen  Liisa Lepist  Anita Rm  Jouko Turkka 《Limnologica》2004,34(1-2):154

Lake Pyhäjärvi, on the border between Finland and Russia in Karelia, is a very valuable clear-water lake of the Lobelia type. It belongs to the European Union's Natura 2000 programme in Finland, and has been included in regional and national monitoring programmes since the 1960s. The main monitoring station is situated near the outlet of the lake. Deterioration of its water quality was suspected already in the 1980s because of decreasing Secchi depths (transparency) and increasing chlorophyll a.The occurrence of algal blooms on the lakeshores is monitored weekly during each summer at one site on Lake Pyhäjärvi (site 1). This is a part of nationwide intensive algae monitoring programme organised by the environmental authorities together with voluntary observers at some 270 lake sites in Finland since 1998. Since 1997, Secchi depth observations have been carried out by volunteers biweekly or monthly at 17 sites on the lake. In the vicinity of one of these transparency observation sites (station 100), intensive monitoring of algae has been carried out. At this lakeshore monitoring site 69 algal observations were made, ten of which recorded algal blooms during the study period 1998–2002. The observed algal blooms were caused by algae of the Anabaena species, mainly by Anabaena lemmermannii. At Lake Pyhäjärvi the number of algal bloom observations received from the public have decreased from the 1990s to the 2000s. The range of Secchi disc transparency was 5.0–8.4 m with a mean value of 6.2 m at station 100 and 4.3–7.7 m (mean 6.1 m) at the main monitoring station 2 during the open water periods in 1998–2002. During this study period, the maximum values at site 100 seem to have increased slightly, which might indicate some improvement in the water quality due to decreased point source loading.We conclude that the intensive algal monitoring results of 5 years at the lakeshore site and the transparency results — both compiled by trained volunteers — reflect an improvement in the state of Lake Pyhäjärvi in Karelia. This conclusion is in accordance with the long-term water quality and short-core studies of sedimentary diatoms in Lake Pyhäjärvi. We suggest that the intensive algal observations and transparency measurements are both suitable methods for the monitoring of lakeshores and lakes, and that both are suitable for voluntary monitoring. We found public participation a good tool for monitoring lakes and lakeshores.  相似文献
