Taxonomic and functional diversity of urban bees of the world
Conservation Biology, EarlyView.Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Evaluating the use of taxonomy in the IUCN Red List
Conservation Biology, EarlyView.Abstract Taxonomy defines the units that conservationists strive to preserve for future generations. However, the discovery of new species and the taxonomic revision of existing species affect conservation efforts. Despite the importance of taxonomy for a species’ conservation, there is currently no overview of how those leading species extinction risk

Role of funders in embedding tests in conservation practice
Conservation Biology, EarlyView.Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.

, 1999 绩效评估是人力资源管理研究和实践中的关键问题，也是难度很大的一个问题，因为它不仅直接关系到选拔的有效性，而且为组织工资报酬制度的制定提供依据，从而影响组织激励机制的建立与作用，所以在人力资源管理中处于一个牵一发而制全身的核心地位。从定义上看，绩效评估（ｐｅｒｆｏｒｍａｎｃｅａｐｐｒａｉｓａｌｏｒｐｅｒｍｒｍａｎｃｅｅ－ｖａｌｕａｔｉｏｎ）是指对工作行为的测量过程，即用一套既定的标准来测量职工的工作表现并将结果反馈给职工的过程。所以，从功能上看，绩效评估是整个人力资源管理中的控制系统，起着监督。控制 ...

Risks of concealing environmental degradation
Conservation Biology, EarlyView.Abstract Current practice seeks to conceal the visual impact of land‐use change (i.e., development). Six percent of development impact assessments in Australia and 14% of the World Bank's assessments recommend visual impact mitigation. This mitigation results in, for example, vegetated buffer strips alongside cleared agricultural areas and earthen ...

Gaoya dianqi, 2021 电力变压器结构、运行工况复杂,影响其健康状态的因素众多,建立有效的变压器健康状态评估模型对其状态进行准确评估是十分必要的。文中提出一种考虑变压器历史运行工况影响的变压器健康状态评估模型。从油色谱试验、电气试验、油化试验数据及现场评估等方面提取相关重要指标作为定量指标和定性指标,通过主客观组合权重和岭型隶属函数完成基于定量指标的变压器状态初步评估结果;考虑变压器历史工况建立定性指标对初步评估结果进行合理修正,完成对变压器健康状态的评估。最后以宁夏地区1台110 kV主变验证了该评估方法的有效性和准确性 ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, EarlyView.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...
