Analytical mapping of research on disaster management,types and role of ICT during 2011–2018

Catastrophic disasters like earthquake and flood cause widespread destruction and financial devastation. This has brought disaster management into limelight making it a burgeoning academic research field. The remarkable rise of ICT (Information and Communication Technology) has instigated the scientific world to incorporate these technologies in disaster management. This study presents scientometric analysis to identify the status quo of research on the management of various disasters and role of ICT in it. This paper uses bibliographic data retrieved from Scopus for the observation period from 2011 to 2018. We provide extensive insights into growth of publications, citation pattern and their connectedness with other subject disciplines. Furthermore, we identify most productive and influential countries, institutes and journals. Our study analyses co-occurrence of keywords using Visualization of Similarities (VOS) Viewer. This structured overview will enhance the understanding of this field leading to more focussed and purposeful research.

Community evacuation following a chlorine release, Mississippi

On 7th September 1986, four miles north of Collins, Mississippi, a train transporting chlorine derailed. Two cars ruptured and gas escaped. As a result, 100 families were evacuated. To study the evacuation process, we conducted person-to-person interviews with sixty-two families staying in the evacuation center. Only 52.5% of the families received their first directive to evacuate directly from police or other officials. Delays in evacuating tended to be shorter when people were warned by the police and were told the reason for evacuating. Lack of personal transportation and preexisting health problems resulted in delays in evacuation. Concerns about evacuation included fear of looting, lack of a place to go, lack of transportation, difficulty in moving with children and elderly persons, and the need to take care of pets. One third of the interviewees reported feeling panic. Community evacuation procedures would be improved if: (1) officials contact all households directly; (2) the warning message addresses people's concerns; and (3) transportation is provided.

Co-ordination for disasters

This paper was prepared in 1978 on the basis of a review of sociological and anthropological fieldwork conducted up to that time. Although theoretical in presentation its conclusions are formulated in accordance with the author's own extensive observations of organizational response to natural disasters in developing countries, especially those having sudden onset. Practical implications for co-ordination agencies and pre-disaster training are drawn.     

黑河中下游防风固沙功能时空变化及影响因子分析

黑河中下游是我国重要的防风固沙生态功能区,分析该区域的防风固沙功能时空变化,明确其主要的影响因子贡献,对于指导荒漠化防治、维护流域生态安全十分重要.该研究基于修正风蚀方程(revised wind erosion equation,RWEQ)、一元线性回归斜率分析、灰色关联分析和GIS技术,分析了2000—2017年黑河中下游防风固沙功能动态变化及其影响因子.结果表明:①2000—2017年,黑河中下游年均防风固沙量为3.2×109 t,年均防风固沙功能约为2.44×104 t/km2;防风固沙量总体呈增强趋势,年均增加6.67×107 t,年均变化率为1.85%.②区域防风固沙功能呈现中游较强,向下游递减的空间分布特征,防风固沙功能较高区约占研究区面积的31.54%,一般区占20.77%,较低区(北部荒漠区)占47.69%;甘肃省张掖市和嘉峪关市防风固沙功能呈增加趋势,回归方程系数(slope)为0~26.29%,占总面积的12.51%;额济纳旗东北部和甘肃省高台县中部防风固沙功能呈下降趋势,回归方程系数为-17.17%~0,占总面积的23.30%.③防风固沙功能主要影响因子中,风力因子最主要,贡献率为30.04%,其次为积雪覆盖、土壤湿度、植被覆盖,贡献率分别为24.57%、24.26%和21.13%.研究显示,防风固沙工程应综合考虑气候变化、植被覆盖、土壤特性及人类活动的复合影响,实行具有空间差异化的方案.

Study of Meteorological Aspects and Urban Concentration of SO2 in Atmospheric Environment of La Plata, Argentina

This article presents and discusses SO₂ (ppbv) concentration measurements combined with meteorological data (mainly wind speed and direction) for a five-year campaign (1996 to 2000), in a site near an oil refinery plant close to the city of La Plata and surroundings (aprox. 740.000 inh.), considered one of the six most affected cities by air pollution in the country. Since there is no monitoring network in the area, the obtained results should be considered as medium term accumulated data that enables to determine trends by analyzing together gas concentrations and meteorological parameters. Preliminary characterization of the behaviour of the predominant winds of the region in relation with potential atmospheric gas pollutants from seasonal wind roses is possible to carry out from the data. These results are complemented with monthly averaged SO₂ measurements. In particular, for year 2000, pollutant roses were determined which enable predictions about contamination emission sources. As a general result we can state that there is a clear increase in annual SO₂ concentration and that the selected site should be considered as a key site for future survey monitoring network deployment. Annual SO₂ average concentration and prevailing seasonal winds determined in this work, together with the potential health impact of SO₂ reveals the need for a comprehensive and systematic study involving particulate matter an other basic pollutant gases.
