基于社会技术系统的复工企业疫情防控风险路径研究*

为对复工企业疫情防控中的风险致因因素进行分析,探寻复工企业疫情防控的风险路径,基于社会技术系统理论,建立宏观工效学模型,通过查阅并分析国家、地方政府、企业文件以及相关文献,从人员、技术、组织管理、内部环境及外部环境5个子系统出发,识别出16个复工企业疫情失控致因因素;运用社会网络分析（SNA）构建复工企业疫情防控关系网络,对各因素节点中心度进行计算,分析各节点在网络中的位置及影响程度;采用贝叶斯网络（BN）进行参数学习和推理学习,找出复工企业疫情失控的最大致因链。结果表明:复工企业疫情失控关系网络中,存在政府监督管理不力→防疫物资筹备不足→日常监管不到位,政府监督管理不力→ 防疫宣传、培训缺失→员工防疫知识欠缺,政府监督管理不力→防疫宣传、培训缺失→日常监管不到位3条最长风险路径。研究结果可帮助复工企业针对最长风险路径中的因素进行管理,从而有效地为复工企业防疫提供理论支持。     

Hurricane Harvey and Greater Houston households: comparing pre-event preparedness with post-event health effects,event exposures,and recovery

Most disaster studies rely on convenience sampling and ‘after-only’ designs to assess impacts. This paper, focusing on Hurricane Harvey (2017) and leveraging a pre-/post-event sample of Greater Houston households (n=71) in the United States, establishes baselines for disaster preparedness and home structure flood hazard mitigation, explores household-level ramifications, and examines how preparedness and mitigation relate to health effects, event exposures, and recovery. Between 70 and 80 per cent of participants instituted preparedness measures. Mitigation actions varied: six per cent had interior drainage systems and 83 per cent had elevated indoor heating/cooling components. Sixty per cent reported home damage. One-half highlighted allergies and two-thirds indicated some level of post-traumatic stress (PTS). Three-quarters worried about family members/friends. The results of generalised linear models revealed that greater pre- event mitigation was associated with fewer physical health problems and adverse experiences, lower PTS, and faster recovery. The study design exposed the broad benefits of home structure flood hazard mitigation for households after Harvey.     

A scoping review of post-disaster social support investigations conducted after disasters that struck the Australia and Oceania continent

This scoping review provides a summary of research findings on social support dynamics in the wake of disasters that occurred on the continent of Australia and Oceania between 1983 and 2013. Forty-one studies, quantitative and qualitative, were summarised, investigating different facets of post-disaster supportive interactions. All inquiries assessed disasters resulting from natural hazards, with the majority of them conducted following events in Australia and New Zealand. The review revealed similar patterns of post-disaster social support dynamics that routinely unfold after disastrous incidents all over the world. Consistent with the disaster mental health literature, the documentation of social support mobilisation and social support deterioration processes was common. Salutary direct effects of supportive behaviours on post-disaster psychological distress were also highly evident. Most studies, however, posed research questions or hypotheses that lacked empirical or theoretical grounding. In conclusion, the review offers several recommendations on how to advance research on post-disaster social support.

Social learning in a policy-mandated collaboration: community wildfire protection planning in the eastern United States

Policies such as the US Healthy Forests Restoration Act (HFRA) mandate collaboration in planning to create benefits such as social learning and shared understanding among partners. However, some question the ability of top-down policy to foster successful local collaboration. Through in-depth interviews and document analysis, this paper investigates social learning and transformative learning in three case studies of Community Wildfire Protection Planning (CWPP), a policy-mandated collaboration under HFRA. Not all CWPP groups engaged in social learning. Those that did learned most about organisational priorities and values through communicative learning. Few participants gained new skills or knowledge through instrumental learning. CWPP groups had to commit to learning, but the design of the collaborative-mandate influenced the type of learning that was most likely to occur. This research suggests a potential role for top-down policy in setting the structural context for learning at the local level, but also confirms the importance of collaborative context and process in fostering social learning.     

新疆“十五”至“十一五”期间影响工业固废产生及排放的主要社会经济因素分析

采用灰色关联分析,找出了影响工业固废量的主要社会经济因素,认为第二产业是影响工业固废的主要因素。第二产业结构比重加大,工业固废量增加。从减少工业固废的角度来看,调整产业结构已是当务之急;环境污染治理投资与工业固废因子关联度最小,说明环保投资已远不能满足环境治理的实际需要,需加大环保投资。     

基于不同价值构成的耕地资源价值评估——以湖南省为例

正确认识和科学评估耕地资源的完全价值,对缓解征地补偿标准过低、土地收益分配不合理以及粮食安全和生态环境等问题具有一定指导意义。基于耕地的不同价值构成,选用相应的评估方法对湖南省不同等级耕地的总价值进行了评估,评估结果为：1~5等耕地资源单位面积的总价值分别为547 24813、481 61077、430 74534、385 86049和336 19093元/hm2;不同等级耕地上3种耕地价值的构成不一样,社会保障价值在所有不同等级耕地总价值中所占比重最大。这一研究结论对于显化耕地资源的完全价值以及抑制耕地资源的过度流失具有积极的作用     

交叉上市公司社会责任缺陷披露的市场反应——基于紫金矿业突发渗漏环保事故的案例研究

伴随着工业化进程加快,社会责任缺失现象日益严重,各类企业违法违规事故层出不穷,其中不乏国有大型控股公司,这种现象引起了投资者、监管机构等利益相关者的广泛关注。在此背景下,研究资本市场对上市公司社会责任缺陷披露的反应具有重要的理论意义和现实意义。本文以交叉上市的紫金矿业为例,采用事项研究法,检验了A股和H股市场对紫金矿业集团股份有限公司发布的一系列有关紫金山铜矿湿法厂污水池突发渗漏环保事故重要公告的市场反应,并比较了两地市场对同一公告的反应差异。研究发现:两地市场对重大事故公告均提前预知并呈负面反应,在公告前A股市场反应程度大于H股市场,公告发布后H股市场投资者更加敏感;两地市场对董事会(临时)决议公告呈正面反应,但H股市场投资者更加谨慎;对处罚公告两市反应不同,A股市场未对处罚公告作出反应,H股市场对处罚公告呈负面反应;总体而言,H股市场与A股市场反应程度存在显著差异。     

自然灾害社会脆弱性评估研究——以上海市为例

基于投影寻踪聚类模型(PPC),结合基于实数编码的加速遗传算法(RAGA),对上海市进行了自然灾害社会脆弱性评估的尝试。结果表明:①灾害社会脆弱性最高的为崇明县,其次为宝山区和金山区;②灾害社会脆弱性最低的是黄埔区,其次是徐汇区和静安区;③总体而言,灾害脆弱性较低的地区集中于上海城市中心区,而城市边缘区的社会脆弱性一般较高。
