1961~2015年西南地区降水及洪涝指数空间分布特征

利用西南地区98个气象站连续完整的日降水序列数据,整合降水强度、持续性指数及等级指数形成降水指数体系并研究该区域降水及洪涝指数的空间分布特征,得到以下主要结论：（1） 1961~2015年,西南地区年降水量（PRCPTOT）与极端降水量（R95PTOT）都呈现出“东多西少、南多北少”的分布形态;持续降水日数（CWD）则表现为“南高北低、西高东低”的分布格局。区域多年平 均PRCPTOT、R95PTOT、CWD分别以-13.12 mm/10 a、1.34 mm/10 a、-0.29 d/10 a的速率变化。（2）西南地区不同等级降水日数具有相似的空间分布特征,均呈现出“南高北低、东高西低”的分布形态。（3）西南地区洪涝强度指数呈由东北向西南递减的分布特征;降水总量越多的地区,洪涝强度反而越低,主要由于单站洪涝强度表征的是降水的波动情况,降水量越多波动越不明显。21世纪以来,该 地区洪涝等级以重级为主,2010年以来连续多年出现特重级洪涝。此外,洪涝强度越大,区域性年度灾害等级越高。该研究对于掌握西南地区极端气候变化规律,从而服务于防灾减灾具有一定的理论意义。     

Idiosyncratic deals in contemporary organizations: A qualitative and meta‐analytical review

Idiosyncratic deals (i‐deals) research focuses on the emergence of customized work arrangements employees negotiate with their employers. This article provides a critical review and synthesis of i‐deals research, combining a qualitative review of i‐deals theory and research with a supplementary meta‐analysis of 23 empirical studies (k = 27 samples, N = 8110 individuals). The qualitative review examines the conceptualization and measurement of i‐deals and identifies patterns and gaps in i‐deals research, while the quantitative meta‐analysis tests the moderating effect of societal cultures on the predictors and consequences of ideals investigated to date. In each section, attention is given to strengths and weaknesses of current approaches to i‐deals theory and research. Future research directions are identified with particular emphasis on the largely unexamined role of i‐deals from a multilevel perspective. Copyright © 2014 John Wiley & Sons, Ltd.     

A review of public acceptance of nature-based solutions: The ‘why’, ‘when’, and ‘how’ of success for disaster risk reduction measures

Nature-based solutions (NbS) are increasingly recognized as sustainable approaches to address societal challenges. Disaster risk reduction (DRR) has benefited by moving away from purely ‘grey’ infrastructure measures towards NbS. However, this shift also furthers an increasing trend of reliance on public acceptance to plan, implement and manage DRR measures. In this review, we examine how unique NbS characteristics relate to public acceptance through a comparison with grey measures, and we identify influential acceptance factors related to individuals, society, and DRR measures. Based on the review, we introduce the PA-NbS model that highlights the role of risk perception, trust, competing societal interests, and ecosystem services. Efforts to increase acceptance should focus on providing and promoting awareness of benefits combined with effective communication and collaboration. Further research is required to understand interconnections among identified factors and how they can be leveraged for the success and further uptake of NbS.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01502-4.     

The many benefits of employee well‐being in organizational research

We undertake three objectives in this Incubator. We begin with a discussion of how well‐being has been considered in organizational research. Second, we provide an overview of the relationship between employee well‐being and such workplace outcomes as job performance, employee retention, and cardiovascular health. Third, we introduce exciting research directions. Copyright © 2012 John Wiley & Sons, Ltd.     

城市内涝灾害应急救援指派模型

为实现应急救援队伍的合理派遣以快速营救受困人员,根据城市内涝灾害特点、城市内涝灾害情况和救援资源的分布,综合考虑应急救援队伍的救援效率、救援可靠性、救援时间等因素,构建多目标应急救援指派模型。运用模糊数学思想,将各目标下的属性值矩阵转化为模糊关系矩阵。针对优化模型的特点,采用反点法对模型进行求解。为证明反点算法的可行性,采用标准匈牙利算法对模型进行求解并加以验证。算例结果表明,多目标优化方案可以进行良好的任务分配,可满足应急救援任务的需要。

新疆绿洲的沙漠化灾害及减灾措施

风沙灾害频发的季节是每年3～6月份。流动沙漠与绿洲直接毗邻的格局增加了下风方向绿洲风沙危害的态势。风沙灾害严重区有莫索湾绿洲,精河,艾比湖地区绿洲,喀什地区绿洲,和田地区绿洲,塔里木河下游绿洲。 新疆绿洲风沙灾害的发展趋势:绿洲外围及河流下游沙漠化土地在继续发展,风沙、尘埃天气显著增加;灌溉绿洲腹地特别是连片的大型绿洲风沙灾害显著减轻,6级以下起沙风基本上不造成风沙灾害;对于突发性,风速达8～9级以上的黑风尘暴,灾害仍不可避免。 采取的减灾措施:针对新疆许多河流下游断流,荒漠生态环境严重退化,沙漠化土地日益扩展蔓延的严峻局面,新疆已经着手进行主要河流的流域规划。塔里木河应急输水工程业已进入实施阶段;减轻对荒漠植被的压力,达到保护绿洲外荒漠植被的目的;加强大型防护林和农田防护林的建设;建立绿洲防止土地沙漠化、减轻风沙灾害的示范区和样板。新疆绿洲风沙灾害的根治仍然是任重道远。
