Structured decision‐making as a framework to incorporate social equity into conservation decisions
Conservation Biology, EarlyView.Abstract Many conservation challenges require negotiating trade‐offs between the needs of different actors. Global frameworks such as the Kunming–Montreal Global Biodiversity Framework explicitly call for diverse participation and social equity in conservation decision‐making.

Dizhen xuebao, 2019 预测效果的科学评价是预测学科必须要解决的问题，对地震预测效果的评价一般分为两种，一种是对单次预测成败的评判，另一种是对方法或手段多次预测效果的统计评分。本文提出了针对单次有震预测是否准确的定量评价方法，即地震预测准确性A值评分法。针对我国地震预测现状，本文约定了准确性评分由预测与实际地震的对应情况（简称“对应度” ）和时、空、强预测窗口的精确程度（简称“精确度” ）综合决定，同时，还给出了对应度的计算方法和精确度的评价标准。通过对四川省地震局2013年2月上报的短期预测意见进行试算 ...

Comprehensive and representative conservation planning for biodiversity of ice‐free Antarctica
Conservation Biology, EarlyView.Abstract Antarctica is designated as a natural reserve devoted to peace and science, with Antarctic Specially Protected Areas (ASPAs) serving as the primary instrument for area‐based biodiversity protection. However, the existing ASPA network lacks the comprehensiveness and representativeness required under Annex V, Article 3(2), of the Madrid Protocol.

高电压测量不确定度的评定与表示——在避雷器绝缘子高电压测量中的应用
Dianci bileiqi, 2012 介绍了有关测量不确定度的基本术语及其概念,包括:测量不确定度、实验标准偏差、标准不确定度、合成标准不确定度、扩展不确定度、包含因子、不确定度的A类评定、不确定度的B类评定、测量误差等。从定义、计算方式、分类、符号、与测量结果的关系、与测量条件的关系等方面分析了测量不确定度与测量误差之间的区别,并简要介绍了测量不确定度和测量误差之间的联系,即测量不确定度是由测量误差引起的,两者都是由随机效应和系统效应造成的。给出了高电压测量不确定度评定的6个基本步骤。在高电压测量不确定度评定示例中 ...

Conservation Biology, EarlyView.Abstract Qualitative approaches are increasingly applied in conservation social science, yet methodological reflection remains limited. Member checking, a process of returning findings to participants for feedback, is widely recognized outside conservation as a means to enhance rigor and reciprocity, but it is rarely reported in conservation research ...

Gaoya dianqi, 2020 电力变压器是电网电力输送中的核心电气设备,合理评估变压器的性能对保证电力系统稳定运行意义重大。文中根据变压器故障的原因和评价指标来源,提出了基于定量修正层次理论的变压器性能评估方法。针对变压器性能评估指标体系中评价因素结构复杂、数量庞大的问题,首先依据指标体系中反映变压器故障的准确程度,筛选出能够反映变压器绝缘性能、油性能、过热性故障和放电性故障的关键指标,建立了变压器性能评估关键指标体系;其次利用层次分析法并结合定量修正评分函数,确定指标的最优权重,得到各指标的评分值 ...
