How identity bias affects perceptions of conservation messages on social media
Conservation Biology, EarlyView.Abstract Public support is essential for conservation, as public opinion can influence decision‐making and policy. Therefore, understanding whether bias toward conservationists due to their identity (identity bias) affects their perceived credibility and support for their recommendations is important.

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 ...

Shiyou jixie, 2015 针对三高气田套管腐蚀难题，分析了套管腐蚀失效因素，设计了应力腐蚀试验方法。用TP110TS和TP95S套管试样，模拟现场井下条件进行不同拉应力、无应力和压应力状态下套管腐蚀试验，并根据试验结果对套管应力腐蚀速率的主要影响因素、腐蚀后力学性能、应力腐蚀敏感性和应力腐蚀门槛值及安全性进行研究。研究结果表明，三高气田套管腐蚀不可避免，拉应力对应力腐蚀具有敏感性；随着拉应力、H2S和CO2含量的增大，套管腐蚀速率加快、力学性能退化，导致其服役安全寿命缩短。据此提出了采用组合套管 ...

Dizhen xuebao利用双差定位法对2010年8月1日至2014年12月31日福建仙游地区中国地震台网中心记录到的地震群进行重定位，并采用P波初动的方法求解出该震群的159个震源机制解，显示该震群的震源机制解结果与背景构造应力场表现明显不一致。为了进一步探究差异性存在的原因，将得到的震群震源机制解结果分区域和分深度求解应力场，结果显示：金钟水库的东南部附近应力方向更远离背景构造应力方向，并且应力形因子小于0.5，中间轴呈现为拉张应力；随着深度的增加，应力场的方向也更接近背景构造应力场的方向。此外 ...

A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education
International Journal of Applied Linguistics, EarlyView.ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI
