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.

Conservation Biology, EarlyView.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Striking a Balance: Stakeholder Perceptions of Risk in Horse Racing
Equine Veterinary Journal, EarlyView.ABSTRACT Background Thoroughbred racing is a major industry, and in recent years, public concerns about equine safety have become more prominent, particularly in relation to on‐track injuries and fatalities. This has challenged the industry's social licence to operate (SLO).

International Journal of Applied Linguistics, EarlyView.ABSTRACT Previous research has established the relationships between motivation, anxiety, teachers’ support, and self‐regulated learning (SRL) in English‐as‐a‐foreign‐language (EFL) learning. Most of the studies, however, have taken a variable‐centered approach in addressing the variable correlations, while learners’ characteristics and variable links ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Spurred by the advancement of educational technology, more language instruction has been offered in online environments. Consequently, teaching practices have had to adapt to digital platforms. Accordingly, teachers’ provision of synchronous written corrective feedback (SWCF) on digital texts has received increasing attention.

Dianci bileiqi对电气设备地震动响应分析应用较多的主要有两种方法——振型分解反应谱法和动力时程法，其中某些关键动力参数的取值在电气设备抗震相关规范中并没有具体规定，实际分析时往往凭个人经验，致使分析结果因人而异、不尽准确。为了在计算分析阶段通过对关键动力参数准确取值，尽可能真实获取结构动力响应，本研究以特高压支柱式电气设备颇具代表性的两种材质的结构本体及加装减隔震装置后的结构为分析对象，在非线性时程分析方面，通过对动力时程法主要参数：振型参与阶数、地震波及峰值加速度的影响对比分析 ...

Jianzhu Gangjiegou Jinzhan, 2016 为了揭示某体育馆屋盖马鞍形钢结构体系的新颖独特,将整体屋盖划分为外围结构和内场结构进行受力分析,介绍了节点形式,总结了结构的各项计算参数。弹性地震分析表明,结构的极限状态分析结果和整体受力性能满足设计要求。针对抗侧斜柱进行了几何非线性稳定分析,计算结果表明未出现失稳现象。通对整体结构的抗连续性倒塌分析,判断出重要构件并借助敏感性分析将构件的重要性进行了排序,并针对抗侧斜柱采用了简化分析方法,最终分析结果表明,杆件失效后整体结构不会发生垮塌。证明了结构方案的安全性和合理性。

International Journal of Applied Linguistics, EarlyView.ABSTRACT Self‐regulated learning (SRL) as a key predictor of language learning has been widely studied, but few studies have examined it from a cross‐linguistic perspective. The present study investigated whether first language (L1) SRL strategy use transfers to second language (L2) SRL strategy use and the conditions under which this transfer occurs ...
