Inclusion of people with disabilities,their needs and participation,into disaster management: a comparative perspective

In the field of disaster management, not many have considered the role and needs of people with disabilities despite their number and condition. The purpose of this paper is to push for specific inclusion of people with disabilities, their needs and participation, into disaster management by studying relevant cases from Indonesia, Korea, and the USA. Qualitative content analysis was used as a major methodology by comparing three factors identified in these nations: government policies, schools and advocacy groups’ efforts, and families and local communities’ awareness. Three models, one from each country, were considered major takeaways from this study: the Indonesian moral inclusion, the Korean medical treatment without exclusion, and the US’ extending social inclusion. In addressing the needs and participation of people with disabilities in disaster management, the following recommendations are put forward: for Indonesia, a move away from olden beliefs and misconceptions on disability (e.g. as a punishment) is imperative. In Korea, relevant fundamental laws (e.g. the Basic Act on Emergency and Safety Management) need to be revised while also studying advanced laws on the subject. For the USA, though the country is already advanced, overall improvement is still needed in terms of association with international non-governmental organizations, increase in the number of (emergency or disaster) response officials, and provision of better medical treatment.     

深圳市工业区VOCs污染特征与臭氧生成敏感性

于2020年9~10月在深圳北部典型工业区开展在线观测以分析该地VOCs污染状况,并使用基于观测的模型(OBM)研究臭氧生成敏感性.观测期间VOCs的总浓度为48.5×10^-9,浓度水平上烷烃>含氧有机物(OVOCs)>卤代烃>芳香烃>烯烃>乙炔>乙腈.臭氧生成潜势(OFP)为320μg/m³,其中芳香烃、OVOCs以及烷烃贡献最大,这3类物种OFP贡献总和超过90%.乙烯与苯呈现“两峰一谷”的日变化特征,主要受到机动车排放的贡献.相对增量反应性(RIR)分析表明,削减人为源VOCs对控制当地臭氧生成最为有效,当中又应优先控制芳香烃;经典动力学曲线(EKMA)分析表明该片区臭氧生成处于过渡区,在开展VOCs区域联防联控的同时,需要在当地进行有力的NOx控制以强化该地区臭氧污染长期管控.     

Climate change and transdisciplinary science: Problematizing the integration imperative

In this article we critically examine the ‘integration imperative’ in transdisciplinary environmental science and build on social constructivist and political theories to suggest alternative approaches of knowledge co-production in transdisciplinary settings. Our argument builds upon a body of literature in social studies of science to cull insights about knowledge co-production, social learning, and the ecology of team science, particularly as it relates to climate change adaptation. Couched in this transdisciplinary literature, we demonstrate, is the assumption that integration necessarily can and should be a regulative ideal. We critique this assumption by examining the ‘messy’ politics of achieving consensus among radically different, and sometimes irreconcilable, ways of knowing. We argue that the integration imperative conceals the friction, antagonism, and power inherent in knowledge co-production, which in turn can exclude innovative and experimental ways of understanding and adapting to climate change. By way of conclusion, the final section explores three alternative models of knowledge co-production – triangulation, the multiple evidence-based approach, and scenario building – and illustrates their application in the context of transdisciplinary research in climate change adaptation in the arctic, focusing on alternative means of cross-boundary engagement with indigenous ways of knowing.     

锅炉过热器爆漏原因的统计分析和预防措施

以100余起公开报道的锅炉过热器爆漏事故案例进行统计分析为基础,将引起过热器爆漏的直接原因归纳为长期超温、短期超温、腐蚀、磨损和焊接缺陷,对产生事故的机理和主要原因进行了探讨和归类,认为运行管理不当是造成过热器爆漏的最重要方面。分析并提出了设计、安装、制造、检修和运行管理过程中对爆漏风险贡献最大的各单因素及其成因。针对造成爆漏的根本原因提出了预防措施,为锅炉的安全运行和合理检修提供了科学依据。     

OBIA与RF结合的龙口市土地利用信息提取方法

为提高中分辨率遥感影像解译精度,本文提出面向对象影像分析（Object Based Image Analysis,OBIA）与随机森林（Random Forest,RF）结合的土地利用信息提取方法。采用Landsat 8 OLI影像,针对不同地物特点,阈值分割和多尺度分割结合创建影像对象,规则集和分类器协同分类,基于Relief F算法分别对光谱特征、纹理特征及所有特征降维筛选特征子集,并与全部特征一起应用RF建模,对龙口市进行土地利用信息提取与比较。结果表明：OBIA与RF结合提取土地利用信息,基于Relief F算法筛选纹理特征,保留完整光谱、几何、空间关系特征构建RF模型,建模错分率为0.0958,分类总体精度和Kappa系数分别为89.37%和0.872,取得较理想结果。该方法可应用于中分辨率遥感影像土地利用信息提取。

COMPARATIVE EVALUATION OF STATISTICAL METHODS FOR WATER SUPPLY FORECASTING1

ABSTRACT: While the correlation coefficient and standard error of estimate are frequently used when comparing models of seasonal water yield, the following criteria may be more important in selecting one model from among several alternatives: rationality of the regression coefficients, the distribution of the residual errors, and the correctness of indicators of the relative importance of the predictor variables. These criteria were used to compare seasonal water yield models that were calibrated using multiple regression, stepwise regression, principal components regression, polynomial regression using a principal components rotation, and constrained pattern search. Hydrologic data from the Upper Sevier River basin in southern Utah were used to illustrate the comparative analysis process. The prediction equations used the April-July streamflow volume as the criterion variable.     

1985-2005年中国城市水源地突发污染事件不完全统计分析

对1985-2005年中国城市水源地突发污染事件进行了统计分析,以从总体上揭示这些事件的发生规律及其对城市水源地和供水安全的危害.采用文献检索方法,通过对1985-2005年<中国环境报>、<人民日报>、新华网等报刊和网络的检索,从发生日期、地点、污染物种类、事件简况4个方面统计中国城市水源地突发污染事件,经整理和筛选后共列出102起.这些突发污染事件的分析结果表明:1)中国城市水源地突发污染事件总体上呈数量逐年增多,危害增大的趋势;2)化学品和污水是主要污染物;3)河道交通事故和工厂泄漏事故是主要风险源;4)突发污染事件一般都造成了比较严重的经济社会影响,但缺乏相应的应急管理机制和应急部门;5)3个典型突发污染事件造成重大经济社会损失并引发社会高度关注,凸现了构建中国城市水源地突发污染事件应急机制的重要性和迫切性.
