Assessing Social Vulnerability to Flood Hazards in the Dutch Province of Zeeland

International Journal of Disaster Risk Science 2019年第2期10卷 233-243页

The 2007 European Union Floods Directive encouraged member nations to pursue a more integrated view of flood risks and management strategies, taking into account social vulnerabilities of residents. To date, most flood-risk analyses conducted by the Dutch government have focused on physical risk. This study utilizes fine-scale data to construct a social vulnerability index for 147 districts of the Dutch province of Zeeland, located in the Southwestern Delta and the scene of widespread devastation following the 1953 North Sea Flood. Factor analysis of 25 indicators of social vulnerability selected from related research in Europe and the United States results in seven factors explaining roughly 66% of the total variance. These factors of social vulnerability in Zeeland are urban density,low-income households, recent population change, female gender, train access, and self-employed and service-sector employment. The index was constructed using the toploading variable in each of these factors, with weights determined by the variance explained by each *** range from a low of 0.20 in Schore, municipality of Kapelle, to the highest score of 0.64 in Oudelandse Hoeve of Terneuzen. The most vulnerable districts are located in South Zeeland, with eight of the 10 found in *** majority of less vulnerable districts are located in Zeeland’s central region.

Measuring Capacity for Resilience among Coastal Counties of the U. S. Northern Gulf of Mexico Region

引用

American Journal of Climate Change 2012年第4期1卷 194-204页

作者： margaret A. reams Nina S. N. Lam Ariele Baker Department of Environmental Sciences Louisiana State University Baton Rouge USA

Many have voiced concern about the long-term survival of coastal communities in the face of increasingly intense storms and sea level rise. In this study we select indicators of key theoretical concepts from the social-ecological resilience literature, aggregate those indicators into a resilience-capacity index, and calculate an index score for each of the 52 coastal counties of Louisiana, Texas, Mississippi, Alabama and Florida. Building upon Cutter’s Social Vulnerability Index work [1], we use Factor Analysis to combine 43 variables measuring demographics, social capital, economic re- sources, local government actions, and environmental conditions within the counties. Then, we map the counties’ scores to show the spatial distribution of resilience capacities. The counties identified as having the highest resilience capaci- ties include the suburban areas near New Orleans, Louisiana and Tampa, Florida, and the growing beach-tourist com- munities of Alabama and central Florida. Also, we examine whether those counties more active in oil and gas develop- ment and production, part of the region’s “energy coast”, have greater capacity for resilience than other counties in the region. Correlation analyses between the resilience-capacity index scores and two measures of oil and gas industry ac- tivity (total employment and number of business establishments within five industry categories) yielded no statistically significant associations. By aggregating a range of important contextual variables into a single index, the study demonstrates a useful approach for the more systematic examination and comparison of exposure, vulnerability and capacity for resilience among coastal communities.

极移会使洲际弹道导弹瞄准计算用的下面几个参数发生变化:地球角速度向量,发射场重力值与天文坐标,瞄准与发射场惯性速度。而这些参数通常是作为常数来处理的。文中对这些参数造成的瞄准误差进行了估计。估计表明,起主要作用的误差是惯性测量装置方位对准误差,此项误差可产生50英尺的横向偏差。利用1899年—1982年的极移数据对极移预测模型的有效性进行了研究。每年修正一次的三项正弦预测模型可使横向偏差减少约85％。

Olivet Nazarene College的大学生地质课程已经按照一次会议明确的教育目的和目标的概念进行了修改。这一课程体系阐明了学生在一门课程中的责任,有利于快速的复习,有助于院内院外各单位进行评价,并且易于对一些课程进行改革。这种方法的一个难于避免的缺点是在最初耗费的时间多。一些评论家认为学生和教员的兴趣和积极性可能受到压抑。这种批评可以用创造性的教学方法加以克服。这一体系被作为一种有效的教学方法加以推荐。
