目的整体解释和归纳一种可行的食品安全评价指标体系。方法基于Web of Science数据库收集的237篇原始文献,利用NVivo11.0软件提取自由节点并提炼树状节点的方式构建基于指标的食品安全监管评价模型,并回归现实验证模型的逻辑性和可靠性...目的整体解释和归纳一种可行的食品安全评价指标体系。方法基于Web of Science数据库收集的237篇原始文献,利用NVivo11.0软件提取自由节点并提炼树状节点的方式构建基于指标的食品安全监管评价模型,并回归现实验证模型的逻辑性和可靠性。结果食品安全是政府、企业、社会等多元主体的共同责任。结论食品安全监管需要政府、食品企业、消费者、媒体、行业协会、私人检测机构等多元主体的良性互动。展开更多
为宏观把握全球范围内煤矿安全研究现状和热点前沿,借助Cite Space分析工具,选取Web of Science(WOS)核心合集数据库作为数据来源,对国内外煤矿安全领域1986-2019年之间发表的1109篇高水平权威文献关键词、作者、研究机构进行热点挖掘...为宏观把握全球范围内煤矿安全研究现状和热点前沿,借助Cite Space分析工具,选取Web of Science(WOS)核心合集数据库作为数据来源,对国内外煤矿安全领域1986-2019年之间发表的1109篇高水平权威文献关键词、作者、研究机构进行热点挖掘、文本统计和图谱呈现。结果表明我国在此领域研究已达到世界先进水平。该领域研究人员和机构间仍需要进一步开展跨地域、跨部门的广域合作。深部煤开采多灾种耦合评价成为该领域关注的重点问题。展开更多
