Damage models for natural hazards are used for decision making on reducing and transferring risk. The damage estimates from these models depend on many variables and their complex sometimes nonlinear relationships with the damage. In recent years, data‐driven modeling techniques have been used to capture those relationships. The available data to build such models are often limited. Therefore, in practice it is usually necessary to transfer models to a different context. In this article, we show that this implies the samples used to build the model are often not fully representative for the situation where they need to be applied on, which leads to a “sample selection bias.” In this article, we enhance data‐driven damage models by applying methods, not previously applied to damage modeling, to correct for this bias before the machine learning (ML) models are trained. We demonstrate this with case studies on flooding in Europe, and typhoon wind damage in the Philippines. Two sample selection bias correction methods from the ML literature are applied and one of these methods is also adjusted to our problem. These three methods are combined with stochastic generation of synthetic damage data. We demonstrate that for both case studies, the sample selection bias correction techniques reduce model errors, especially for the mean bias error this reduction can be larger than 30%. The novel combination with stochastic data generation seems to enhance these techniques. This shows that sample selection bias correction methods are beneficial for damage model transfer.  相似文献

当前我国以损害管理为主的生物安全法律规制范式尚未全面、系统地贯彻风险预防理念,条块分割的管理体制导致主管部门与地方政府以及部门之间存在信息壁垒,缺乏协调与合作,且生物安全规制机制仍体现出浓重的行政规制色彩,生物安全风险预防制度体系也出现严重缺失,无法适应风险社会中保障生物安全的迫切需要。生态风险的客观性与不确定性,以及从环境管理向环境治理转型的实践需求则为生物安全法律规制范式从损害管理向风险治理的转变奠定了正当性基础。在具体进路上,生物安全法律规制范式从损害管理到风险治理的转变应当从风险预防原则的引领、生物安全风险合作治理、生物安全风险治理的制度建设等方面展开。  相似文献

基于CHARLS 2015数据,采用倾向得分匹配法实证分析参加医疗保险对农村居民健康的影响。研究发现:参加医疗保险对农村居民的日常活动能力和自评健康影响不显著,参加医疗保险对农村居民认知能力具有显著的正向影响。据此提出,应进一步提升社会医疗保险保障水平、扩大社会医疗保险保障范围、促进商业医疗保险有序发展、推进"三医"高效协同联动等,以充分发挥医疗保险的健康保障功能,从而进一步提升参加医疗保险对农村居民健康的正向影响。  相似文献

Recent guidance on safety monitoring during drug development, issued by regulatory authorities in the United States and European Union, indicate a shift in focus towards aggregate safety monitoring and scientific evaluation of integrated safety data. The call for program‐level reviews of accumulating safety data, including from ongoing studies, provides an opportunity to leverage the scientific expertise and medical judgment of safety management teams with (a) a multidisciplinary approach, (b) quantitative frameworks to measure level of evidence, and (c) assessments that are product‐specific and driven by medical judgment. A multidisciplinary team, regularly reviewing aggregate safety data throughout the development program, is vital not only for early signal detection but also for generating a better understanding of the accumulating data and context needed for decreasing false alarms.  相似文献

基于可及性理论,从医疗服务资源的可获得性和可达性两个角度量化各地级市疫情防控定点医疗组织机构的空间分布特征以及空间组合模式,并探讨其对疫情防控效果的影响。研究结果显示,在控制了城市基本特征、人员流动程度、基础医疗资源状况和省级固定效应之后,按人口聚集分布定点医院显著负向影响各城市累计确诊病例数,而按人口聚集分布发热门诊显著增加确诊病例数。相比于其他空间组合模式,定点医院按人口聚集分布,发热门诊按空间平均分布的组合方式对于疫情防控的效果最好。随着疫情严重程度的上升,按人口聚集分布定点医院对于疫情的抑制作用以及按人口聚集分布发热门诊对疫情防控的负面影响被进一步强化。  相似文献

远程医疗作为一种新型医疗模式,突破了医疗资源在时间与空间上的限制,为优化医疗资源配置、实现优质医疗资源下沉、提高基层医疗服务能力提供了有效途径,具有良好的经济效益与社会效益。在国家相关政策的有力推动下,城市医疗集团结合自身发展需求开始大力发展远程医疗。文章运用文献研究法和态势分析法(SWOT analysis,SWOT分析),探讨了城市医疗集团发展远程医疗的内部优势(S)、劣势(W)以及外部机会(O)、挑战(T)。最后运用SWOT矩阵分析得出如下结论:抓住发展契机,发挥政策导向(SO策略);增加财政投入,促进多方参与(WO策略);完善政策法规,加强宣传力度(ST策略);线上线下结合,尝试差异化服务(WT策略)。  相似文献

随着我国人口老龄化不断加剧,切实保障好老年人健康格外紧迫。基于此,文章采用中国健康与养老追踪调查数据从身体机能健康和心理健康两个维度实证考察了医疗保险对老年人健康的影响及其作用机制。研究发现,医疗保险能够显著提高老年人身体机能健康和心理健康。机制研究表明,医疗保险能够显著提高老年人医疗服务利用、降低老年人慢性病发生率进而影响到老年人健康。因此,进一步扩大老年人医疗保险覆盖面、提高医疗保障水平、促进医疗服务公平性和可及性,是我国人口老龄化不断加剧状况下保障老年人健康的重要途径。  相似文献

The anatomy lab has been studied by sociologists interested in professional socialization since the 1950s. This is because the act of dissecting a cadaver is thought to be foundational for both the student's medical knowledge and the development of the student's professional identity. In this paper, I revisit the anatomy lab both historically and ethnographically. Drawing on theoretical insights from the laboratory ethnography tradition within science and technology studies, I show that students use material artifacts in the lab to support their “surgical identity play.” This activity is structured by the laboratory's performative architecture even while it is unsupervised by anatomy faculty. While many analyses of professional socialization focus on how students learn to interact with patients during their training, I show that the anatomy lab experience is an important form of professional socialization because here students learn to employ surgical instruments, language, and dress, and begin to relate to each other as colleagues.  相似文献

ABSTRACT

With fires, storms, social protests, and climate strikes sweeping the world, 2019 should have been a tipping point in how the world responds to global heating. This was the backdrop to the COP25 climate change summit which took place in Madrid in December 2019. This paper assesses the outcomes of the meeting and the path towards the critically important meeting in Glasgow at the end of 2020. It analyses and explains the key points of contention over levels of ambition, the rules which should govern global carbon markets and sensitive issues such as loss and damage associated with the impacts of climate change. The analysis is situated within a broader geopolitical and economic context of right-wing populism, deepening forms of marketization and financialization of responses to climate change and against a background of a world increasingly feeling the effects of the climate crisis.  相似文献
