工业企业财产保险风险查勘(评估)模型研究

核保和风险控制工作需要全面掌握标的的风险状况，但目前保险公司普遍采用的检查表评估方式因其自身的缺陷却达不到这一要求。通过建立财产保险风险查勘(评估)模型，运用系统安全工程的理论与方法识别、分析危险，并建立分析查勘评估指标体系，从整体上对保险标的进行了风险评估。采用排序法和直接赋值法综合分析各专家的意见，计算得到其体系的权重值。与保险的实际操作相结合，得出标的的整体风险等级，并找出保险标的的风险薄弱环节，以便承．保后有重点地进行整改。

Toward understanding the active SETI debate: Insights from risk communication and perception

Insights from the robust field of risk communication and perception have to date been almost totally absent from the policy debate regarding the relative risks and merits of Active SETI or Messaging to Extraterrestrial Intelligence (METI). For many years, the practice (or proposed practice) of Active SETI has generated a vigorous and sometimes heated policy debate within the scientific community. There have also been some negative reactions in the media toward the activities of those engaged in Active SETI. Risk communication is a scientific approach to communication regarding situations involving potentially sensitive or controversial situations in which there may be high public concern and low public trust. The discipline has found wide acceptance and utility in fields such as public health, industrial regulation and environmental protection. Insights from the scientific field of risk communication (such as omission bias, loss aversion, the availability heuristic, probability neglect, and the general human preference for voluntary over involuntary risks) may help those who have participated in either side of the debate over Active SETI to better understand why the debate has taken on this posture. Principles of risk communication and risk perception may also help those engaged in Active SETI to communicate more effectively with other scientists, the public, with the media, and with policy makers regarding their activities and to better understand and respond to concerns expressed regarding the activity.
