小兴安岭森林生态区位重要性评价研究

根据《生态功能区划技术暂行规程》和《关于黑龙江省生态功能区划编制说明》,创新性地构建以生态环境现状、生态环境敏感性、生态系统服务功能重要性为一级指标的森林生态区位重要性评价体系,并且对小兴安岭地区进行了评价,得到小兴安岭中部地区、北部地区、西北部地区、南部地区的森林生态区位重要性分别是62.23、60.19、57.95和54.14,说明小兴安岭中部地区的森林比其他地区的森林有较高的生态区位重要性,建议在投入森林建设资金时,应对森林生态区位重要性较高的地区倾斜,以利于推进小兴安岭森林的可持续发展战略。

VaR在我国商业银行市场风险管理中的应用研究

VaR是当前国际主流的市场风险计量工具。由于我国金融市场与西方成熟金融市场存在着很多差异,我国商业银行运用VaR计量金融市场风险时面临许多约束条件,目前国内现有的VaR体系在风险管理过程中仅起参考作用,尚未真正用于决策。为提高自身的风险管理水平,银行应聘请业内和学术界的专家对有关部门的领导和业务人员进行培训,从外界吸收专业的风险管理人才,为将来更好地开展风险计量工作作好人才储备;重视数据积累,加紧完善风险管理数据库,为风险管理信息系统有效运转提供数据支持;在对单一风险来源的金融产品尝试开展风险计量工作的基础上,对同时受多种风险因素影响的金融产品和多种资产构成的组合及二级金融衍生产品开展风险计量工作。     

Measuring and improving safety culture in organisations: an exploration of tools developed and used in Belgium

To support organisations in addressing their safety culture, practical tools have been developed worldwide. Based on such practical tools, it is possible to measure where an organisation is situated regarding its safety culture in order to identify priority areas, formulate appropriate improvement strategies and determine changes over time. In this paper, it is examined which practical tools to measure and improve safety culture are provided on the Belgian market. In total, 15 Belgian tools were identified, of which 8 agreed to cooperate. Amongst the included tools, there is a lot of variation regarding the methods to diagnose the safety culture and the overall procedure to improve the safety culture. The importance to adapt the tool to the specific needs and context of organisations is acknowledged in most of the tools, as well as the importance to use a multi-method approach to measure the safety culture. Also, it is recognised that all hierarchic levels should participate during the process of diagnosing the safety culture. A point of attention is this overall participation during the validation of the results of the diagnosis, and the priority setting of the recommendations, which is mainly done by the higher management. The development of the Belgian tools is based on experience with a focus on direct practical application, which leads to the fact that none of the tools are validated through scientific evidence. Another point of attention is that organisations pay too little attention at the continuity of safety culture research. And finally, the question can be raised if the safety culture tools actually address the concept ‘safety culture’, or if they address only a subset of the concept. When safety culture is addressed, a comprehensive approach should be used, where technological, organisational, human and external aspects are taken into account as interacting and interrelating elements.
