Reconstructing Old Chinese *‐ts Using Han‐Time Material
Transactions of the Philological Society, EarlyView.Abstract Baxter & Sagart (2014b) reconstruct *‐Vt‐s on the basis of Middle Chinese reflexes in ‐jH (from some OC *‐s) coupled with either etymological or graphic connections to words in Middle Chinese ‐t. This approach, while perfectly sound, can suffer from lack of etymological or graphic data, leading to missed reconstructions. Since Old Chinese *‐ts

Conservation Biology, EarlyView.Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Jianzhu Gangjiegou Jinzhan, 2023 在基于性能的抗震设计中，以弹塑性分析方法对构件进行抗震性能评价至关重要，而构件性能评价指标的选择与所采用的分析方法密切相关。以受弯与压弯钢构件为研究对象，对比了弹塑性分析中基于弯矩-转角、弯矩-曲率、应力-应变三种力学模型的模拟方法，并分析了与之对应的转角、曲率、应变三类评价指标的应用特点。在介绍相关试验和研究成果的基础上，对比分析了循环加载和倒塌一致性加载模式下构件变形能力的差异，同时综合考虑截面宽厚比等级和轴压比等因素，提出了基于应变指标的钢构件性能评价准则。通过平面钢框架算例 ...

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery
Conservation Biology, EarlyView.Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Gaoya dianqi, 2016 针对并网风力发电机组性能分析评估中存在大量定性指标、各指标模糊性和随机性并存的问题,提出了基于云重心评判法的并网风电机组性能分析评估模型。首先从技术参数、整体功能、系统可靠性及机组维修性4个层面分析并构建了风电机组性能分析综合评价指标体系。然后将各指标值转化为云模型并确定各个指标的权重值。最后计算出修正的加权偏离度,将其输入定性评判云发生器得到风电机组性能评估结果。运用所提方法对某型风力发电机组性能进行分析,并与模糊综合评判法进行比较,验证了该模型的优越性和有效性。

Conservation Biology, EarlyView.Abstract Procedural, distributional, recognitional, and epistemic justice aspects of conservation interventions are well documented in contexts where pastoralism is a key livelihood and way of life. Geospatial analyses and representations of wildlife conservation and restoration that are increasingly applied in pastoralist rangeland socioecological ...
