Identifying and developing effective post‐2020 conservation bridging leaders
Abstract Effective bridging leaders interact within and outside their group to facilitate collaboration required in multistakeholder contexts. This is particularly crucial to community‐based conservation interventions that strive to achieve both ecological and social objectives by actively engaging or devolving decision‐making and management authority ...

Abstract Posttraumatic stress disorder (PTSD) and alcohol use are highly prevalent among military veteran populations. Several theories have been proposed to account for the comorbidity between PTSD and problematic alcohol use, but research examining the symptom‐level associations between the two is limited.

中国高速铁路大量采用高架桥结构,研究雷电环境下高架桥接触网系统电场分布情况对于高速铁路雷击机理的阐明具有重要意义。文中结合先导发展模型以及中国高铁接触网系统实际参数,建立了高架桥接触网系统三维电场仿真模型,并对先导模型进行等效处理。基于此,分析了接触网系统周围电场分布情况,并对高架桥区段以及路基段的电场进行对比研究,研究发现:高架桥区段接触网系统周围场强明显大于路基段,因此在高架桥区段防雷措施应该更加严格;高架桥内部钢筋结构实则对接触网系统周围电场是削弱作用,并提出电容等效模型对该现象进行解释 ...

川藏铁路沿线雷暴活动频繁,地质环境恶劣,严重威胁到列车牵引供电系统的安全运行。川藏铁路全长81%修建在高架桥上和隧道内,相比于平地上的接触网更容易受到雷害影响。通过电气几何模型对高架桥上单线接触网遭受直击雷进行分析,在不同高架桥高度下计算了直击雷的引雷范围和雷击跳闸概率,提出了在川藏线雷害严重地区架设避雷线、改善接地等防护措施。研究表明:引雷宽度随高架桥的高度近似正比增长,AF线直击雷跳闸率是T线的近三倍,应重点防护AF线;避雷线对AF线和T线保护效果良好;雷暴日高的地区 ...

高大施工支架是大跨度复杂桥梁工程中常用的钢结构支撑系统。实际工程中由于高大施工支架加工安装误差、超限受力或不均匀受力等影响,会导致钢结构施工支架存在节点连接不牢固、杆件弯曲变形等初始缺陷。为明晰初始缺陷对桥梁高大施工支架整体稳定性能的影响规律,首先开展了桥梁高大施工支架的线性屈曲分析;进而探讨了节点半刚性、杆件初弯曲等初始缺陷对桥梁高大施工支架极限承载力的影响规律。为提高桥梁高大施工支架极限承载力的求解精度,引入刚度系数α来衡量节点半刚性值,综合考虑节点体对杆件计算长度的影响 ...

ABSTRACT Rechargeable aluminium‐ion batteries (RAIBs) are promising candidates for sustainable energy storage owing to their low cost, safety, and resource abundance. However, the lack of durable cathode materials restricts their development. Here, we propose a topology‐guided design strategy by synthesizing three thioether‐bridged naphthoquinone ...

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

ABSTRACT Interlingual translation, as defined by Roman Jakobson, refers to the transfer of meaning between languages. However, this concept has often been conflated with linguistic shifts between distinct cultures and nation‐states. To challenge this misconception, I propose the concept of self‐consumption translation (SCT), a subfield of interlingual ...
