Conservation Biology, EarlyView.Abstract Achieving global conservation policy goals requires the ability to set and measure progress toward science‐based targets for biodiversity. The species threat abatement and restoration (STAR) metric was developed to enable actors to set science‐based targets for species.

Multi-modal fMRI study on brain structure and function in different factors induced rat chronic obstructive pulmonary disease [PDF]
, 2015 慢性阻塞性肺病（chronicobstructivepulmonarydisease，COPD）脑结构和功能的异常在近些年受到了越来越多的研究关注。先前的神经影像学研究已经发现COPD伴随着白质完整性的损害和灰质的丢失，以及功能连接网络的异常。但是吸烟和非吸烟(如慢性肺部炎症)诱导的COPD病人脑部形态学和功能的异同，以及吸烟和感染因素的综合诱导是否加重了脑损害尚不清楚。致病因素和COPD病人脑部异常的特征性对应关系仍待进一步的探究 ...

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases
World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

The Research about Performance Audit in Colleges and Universities Based on Risk-oriented Mode for N Private College [PDF]
, 2016 随着高校建设及规模的发展，国家财政对高校投入逐年增多，高校可供支配的资源日趋多样化，也给高校带着了风险和机遇。如何合理配置资源，提高高校的风险防范能力成为教育监管部门、高校管理人员、内部审计人员共同关注的内容。而利用风险审计和绩效审计等多元化的审计思路对高校各项活动进行综合评价，促进高校关注潜在风险、合理配置资源，为高校的管理提供决策依据。 当前，由于缺乏完善的绩效评价体系和科学的绩效审计风险量化方法，我国高校的绩效审计还停留在就理论开展分析与讨论的基础研究阶段 ...

Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

供应链上的风险因素识别和评价研究——基于权变理论和模糊集合的视角 [PDF]
, 2013 供应风险或供应中断的可能性是供应链管理面临的一大挑战,评价供应链上的不确定因素的风险水平是供应链上的风险管理的关键步骤。文章首先从权变理论的视角提出了一个识别和预测供应链上的风险的新方法,即从结构性和随机性两个维度来分析归类影响供应链绩效的风险因素。同时,基于这些风险因素,论文采用了计算模糊集合信度结构的方法 ...

Evolution of research on global amphibian declines
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract In the late 1980s, the scientific community became aware of severe, enigmatic amphibian population declines. These declines triggered a wave of research focused on quantifying their extent and identifying key drivers. We used text‐analysis techniques, including topic modeling and geoparsing, to examine the evolution of research focused on ...
