背景：心房纤颤（简称房颤）与死亡和心血管事件（特别是卒中）危险性增加相关，因此，预防新发房颤是一个重要的临床问题。虽然心电图左心室肥厚（electrocardiographic left ventricular hypertrophy，LVH）的存在及其严重程度可以预测房颤的发生，但是心电图LVH消退是否与房颤发生率下降相关尚不清楚。目的：验证降压治疗期间心电图LVH消退或持续消失与房颤发生率下降相关且独立于血压水平及治疗模式的假设。设计、方法及参试者：1995～2001年于8831例男性和女性高血压患者中进行双盲、随机、平行分组研究。患者年龄55～80岁（中位数，67岁），均根据心电图Comell电压-间期乘积或Sokolow—Lyon电压标准诊断LVH。患者无房颤史，基线心电图无房颤，已入选氯沙坦干预降低终点事件高血压研究。干预：氯沙坦或阿替洛尔治疗方案，6个月时进行随访评估，之后每年随访，直至患者死亡或试验终止。主要观测指标：基线及随访各时点心电图LVH与新发房颤的相关性。心电图LVH的测量使用性别校正的Comell乘积标准（{RavL＋Sv3[女性＋6mm]}×QRS间期）。结果：经过平均（SD）4．7（1．1）年的随访，治疗期间心电图Comell乘积标准LVH消退或持续消失的患者有290例新发房颤（发生率为14．9／1000病人-年）；而心电图LVH持续或进展的患者则有411例新发房颤（19．0／1000病人-年）。时间依赖Cox分析显示，在校正治疗效果、基线房颤危险因素差异、基线及治疗期间血压以及基线LVH严重程度后，治疗期间Comell乘积标准LVH降低作为一种时间变异协变量与新发房颤下降相关。Comell乘积每下降1050mm×msec（每个SD），新发房颤就下降12．4％（校正风险比[hazard ratio，HR]，0．88；95％可信区间[confidence interval，CI]0．80～0．97；P=0．007）；氯沙坦减少高血压患者发生房颤的益处优于阿替洛尔（HR，0．83；95％CI，0．71～0．97；P=0．01）。结论：原发性高血压患者在降压治疗期间，心电图Comell乘积标准LVH消退与新发房颤下降相关，而且独立于血压和治疗方案。这些发现提示，以降低或预防心电图LVH为目标的降压治疗可以降低新发房颤的发生率。

Disaster Knowledge Gaps: Exploring the Interface Between Science and Policy for Disaster Risk Reduction in Europe

International Journal of Disaster Risk Science 2020年第1期11卷 1-12页

Expert scientific knowledge is fast becoming an integral part of disaster management, and, in the process, is changing the role of science for the reduction of disaster risks at the policy level. Yet science and policy operate in different domains between which there are often competing interests and modes of valuing knowledge. Based on research done as part of the research project Enhancing Synergies for Disaster Prevention in the European Union(ESPREssO), we discuss three major issues facing European Union member states with respect to the interface between science and policy for disaster risk reduction:knowledge transfer, disaster expertise, and risk *** doing so, we hone in on three gaps: an epistemological gap, an institutional gap, and a strategic gap. We argue that these gaps can help explain underlying systematic challenges for the integration between science and policy for disaster risk reduction. These gaps need to be addressed by focusing on changes at the governance level.

The Chinese Dream of a More Progressive Welfare State： Progress and Challenges

引用

Fudan Journal of the Humanities and Social Sciences 2015年第4期8卷 571-583页

作者： kristian Kongshoj Centre for Comparative Welfare Studies Aalborg University Fibigerstraede 1 9220 Aalborg ODenmark

＂The Chinese Dream＂ and its ideational precursors in official discourse touch upon issues of social policymaking. More specifically, official China has stated the goal of achieving a ＂moderate＂ or ＂appropriate＂ universal welfare state in order to mitigate increasing inequality and the individualization of social risk. Consequently, the new millennium witnessed a wave of social reforms in China's Mainland, the most significant of which were arguably within the policy fields of health insurance, pensions and unemployment protection. This paper reviews reform efforts within these three policy fields and discusses progress and looming challenges with the concept of universalism as the yardstick. From the perspective of universalism, the social right dimensions of coverage （the share of the population included）, generosity （benefit levels or adequacy of welfare proved for those included） and financing （such as state, contributions or private） are quintessential. Coverage of social protection has increased significantly with new schemes in all three policy fields. The hukou divide in coverage of social insurance is not as pronounced as before, especially in health insurance. However, major challenges still persist. Declining benefit generosity or adequacy has been a tendency in both pensions and unemployment protection. The pension system also faces problems of financial fragmentation and unsustainability. The health insurance system is still inadequate in terms of protection against health risks, particularly serious or chronic illnesses. These issues are more pronounced in schemes catering to rural residents or urban residents outside the labor market. This reflects that schemes for urban workers are still much more generous. In this regard, recent tentative efforts to integrate the divided welfare system should be noted.

Identity-aware convolutional neural networks for facial expression recognition

引用

Journal of Systems Engineering and Electronics 2017年第4期28卷 784-792页

作者： Chongsheng Zhang Pengyou Wang Ke Chen Joni-kristian Kamarainen The Big Data Research Center Henan University Kaifeng 475001 China Department of Signal Processing Tampere University of Technology Tampere 33720 Finland

Facial expression recognition is a hot topic in computer vision, but it remains challenging due to the feature inconsistency caused by person-specific 'characteristics of facial expressions. To address such a challenge, and inspired by the recent success of deep identity network (DeepID-Net) for face identification, this paper proposes a novel deep learning based framework for recognising human expressions with facial images. Compared to the existing deep learning methods, our proposed framework, which is based on multi-scale global images and local facial patches, can significantly achieve a better performance on facial expression recognition. Finally, we verify the effectiveness of our proposed framework through experiments on the public benchmarking datasets JAFFE and extended Cohn-Kanade (CK+).
