基于聚类分析的城乡结合部群体性突发事件归类研究

城乡结合部群体性突发事件是影响经济发展、社会稳定的重要根源。为实现对城乡结合部群体性突发事件的归类研究,基于聚类分析理论,探究了我国城乡结合部管理现状以及各类群体性突发事件的原因和具体表现形式,构建了分布聚类模型,利用MATLAB软件生成聚类分析的谱系图,动态模拟了群体性突发事件、原因、表现形式之间的相互关系。研究表明:城乡结合部群体性突发事件基于各类原因呈现不同的表现形式,根据造成群体性突发事件各原因之间的相似度,将城乡结合部群体性突发事件归类为以征地拆迁为主线的经济利益冲突、以执法不当为导向的政治矛盾、以打架斗殴为主要形式的个体冲突、以信访维权等为基础的社会纠纷、以群体竞争为代表的组织斗争。在对城乡结合部群体性突发事件的管理中,根据事件所属的类别,可以制定明确的预警计划,从根本上降低城乡结合部群体性突发事件的发生率,为政府等相关部门的预警管理工作提供借鉴和参考。     

The application of geographic information systems and global positioning systems in humanitarian emergencies: lessons learned,programme implications and future research

Geographic information systems (GIS), global positioning systems and remote sensing have been increasingly used in public health settings since the 1990s, but application of these methods in humanitarian emergencies has been less documented. Recent areas of application of GIS methods in humanitarian emergencies include hazard, vulnerability, and risk assessments; rapid assessment and survey methods; disease distribution and outbreak investigations; planning and implementation of health information systems; data and programme integration; and programme monitoring and evaluation. The main use of GIS in these areas is to provide maps for decision-making and advocacy, which allow overlaying types of information that may not normally be linked. GIS is also used to improve data collection in the field (for example, for rapid health assessments or mortality surveys). Development of GIS methods requires further research. Although GIS methods may save resources and reduce error, initial investment in equipment and capacity building may be substantial. Especially in humanitarian emergencies, equipment and methodologies must be practical and appropriate for field use. Add-on software to process GIS data needs to be developed and modified. As equipment becomes more user-friendly and costs decrease, GIS will become more of a routine tool for humanitarian aid organisations in humanitarian emergencies, and new and innovative uses will evolve.     

'Scaling-up' in emergencies: British NGOs after Hurricane Mitch

This article examines research on NGO 'scaling-up' in a disaster context and links it to a broader discussion on whether scaling-up is a useful concept for understanding NGO processes in an emergency. Using concepts of scaling-up from development literature, research findings from a study of the responses of British NGOs to Hurricane Mitch in Central America are presented. The article assesses the extent and type of scaling-up that occurred, constraints faced by the agencies and the impact of scaling-up on support to partners. Broader issues relating to scaling-up post-Mitch are also explored. The conclusion suggests that while the concept of scaling-up is useful, the tendency for its use to refer to organisational growth has limited a wider understanding and evaluation of the role of Northern NGOs in humanitarian crises.     

The rationality of resistance: alternatives for engagement in complex emergencies

The different conceptualisations of conflict in the complex emergency literature have profound implications on the perception of the agency of different groups and the prospects for conflict management. While much recent analysis has focused on the rational political and economic functions of violence, relatively little analysis has focused on why the majority of people chose not to resort to violence. Using Foucault's analysis of power relations, a new framework for conflict analysis is proposed which includes non-violent resistance as well as violence as a means of domination. Non-violent resistance is explored as a rational, highly adaptable response to acts of domination. A comprehensive understanding of conflict must recognise local forms of resistance and identify the barriers and opportunities for the engagement of the international humanitarian community with these groups. This engagement can be used to foster capacities for the creation of legitimate, inclusive, non-violent political and economic processes in the attempt to provide alternatives for everyone in the conflict. If the purpose of the study of complex emergencies is to understand the nature of various conflicts and, based on that understanding, make recommendations for possible routes to conflict management, the analysis of local resistance and efforts to foster it must become a major aspect of the research agenda.     

Does nutritional surveillance have a role to play in early warning of food crisis and in the management of relief operations?*

A major area of investment in data collection in developing countries has been that of nutritional surveillance and monitoring. From recent debate it is clear that there is currently no consensus on the potential role of nutritional status as an early warning indicator. The author presents a synthesis of the broad spectrum of views on the role nutritional surveillance could or should have in early warning. Conceptual problems and technical difficulties are reviewed in the light of recent experiences in Africa and Asia. The author raises a number of issues for future discussion in this ongoing debate.

四川省2010~2019年突发环境事件时空分布特征分析

近年来,四川省高度重视环境应急管理工作,环境应急处置能力不断提升,但环境风险形势依然严峻,突发环境事件时有发生。通过对2010~2019年四川省10年突发环境事件进行统计分析,浅析四川省突发环境事件的规律特点,以期为四川省生态环境风险防控提供科学依据。研究表明,四川省突发环境事件呈现多发高发态势,6~8月为突发环境事件高发期;安全生产事故和交通事故次生的突发环境事件是主要事件类型;成都市和广元市是突发环境事件的高发区域;油类污染物和酸碱类污染物是主要污染物类型;跨界流域突发环境事件发生频率较高。应从流域突发环境事件风险评估、企业环境安全主体责任、环境应急物质储备体系和突发环境事件联防联控等方面加强四川省环境应急管理。

海上突发环境事件生态系统服务损失评估进展

评估海上突发环境事件对生态系统服务造成的损失,对落实生态损害赔偿制度、保证生态系统服务与功能正常发挥具有重要意义.基于生态系统服务的定义,明确了生态系统服务损失的内涵,是除直接经济损失外,生态系统产生的供给、调节、文化和支持等公益服务的损失.阐述了国内外关于海洋生态系统服务损失评估的研究现状及实践,重点介绍了美国自然资源损害评估（NRDA）体系中生境等价分析法和资源等价分析法的基本假设与主要步骤,通过等价分析法确定生态恢复工程的规模,并结合生态系统服务价值评估的研究成果确定损失.我国学者借鉴NRDA体系等开展了大量研究,提出环境损害鉴定评估、溢油生态损害评估等方法,并在"塔斯曼海"号溢油、蓬莱19-3油田溢油等典型案例中进行应用及优化,比较了不同评估方法差异及影响因素.评估损失必须首先确定事件对海洋生态的影响范围与影响程度、受体类型及敏感度等关键因子,可采用现场监测、遥感及扩散模型等方法确定影响范围与程度,在实践中一般需要综合应用、互相补充.从管理和技术层面,分析了我国海上突发环境事件生态系统服务损失评估研究现状与应急管理需求的差距,在此基础上建议:①建立健全法律体系,细化生态损害评估的责任、内容和要求,明确将生态系统服务损失纳入生态损害赔偿;②构建技术评估体系,根据化学品性质、生态系统类别及特征等,分类出台一系列技术标准;③建议在遥感遥测技术、化学品泄漏数值模型等方面进一步开展研究,提高准确度和时效性.
