Exploring legal‐ and health‐risk messaging to reduce demand for elephant skin
Conservation Biology, EarlyView.Abstract Asian elephants (Elephas maximus) are poached for an illegal trade in their skins, which are used in traditional medicine in Africa and Asia. We explored whether messages about the legal and health risks of using elephant skin for medicinal purposes (stomach illness) could reduce such consumption.

, 2012 以县域为研究单元,运用熵模型、GIS技术、变异系数、锡尔系数分解等方法,对1980-2009年新疆县域经济综合发展水平的空间格局、内部差异演化及其机理做出定量化测度与评价。结果表明:(1)2009年新疆经济发展水平在均量、增量及效益分量中呈现出各自的空间分异特点;自1980年以来新疆区域经济发展的重心不断北移,极化中心基本显现。(2)以变异系数测度的县域经济极化态势呈波动减小特征,且差异大致可以分为3期扩张期和3期收缩期;扩大区域差异贡献率大的因子逐渐从增量转化为均量和效益 ...

Shuitu Baochi Xuebao, 2004 对2003年6～10月羊草草地和大豆地的盐渍化特征(含水量、pH值和含盐量)的动态变化进行分析，并对比2种土地覆被类型之间的变化差异，结果发现：羊草草地和大豆地含水量变化与采样区降雨量的变化有相同趋势，但在采样初期和末期，大豆地含水量要大于羊草草地；对于pH值和含盐量，在土壤剖面0～60cm，两种覆被类型不同层次动态变化一致，大豆地变化的一致性可达到更深层次，但是其峰值要比羊草草地滞后20天左右出现，同时2种土地覆被类型pH值和含盐量的峰值均滞后于含水量的峰值 ...

, 2003 一种催化裂化汽油的芳构化加氢异构化脱硫改性的工艺，催化裂化汽油全馏分或经过分馏后的轻馏分进入一个芳构化加氢异构化脱硫改性反应器，进行烯烃芳构化和加氢异构脱硫反应，降低汽油中烯烃和硫含量，使得到的产品汽油中烯烃含量符合要求。从芳构化加氢异构化脱硫改性反应器出来的汽油，如果硫含量符合要求，直接得到汽油产品；如果硫含量不符合国家标准，先经过加氢脱硫，再进行无碱脱臭，然后得到汽油产品 ...

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

Dianci bileiqi, 2015 内蒙古东部地区地理位置独特,能源丰富,输电线路担负着向外省输送电能的重要任务,线路里程长,地形地貌复杂,线路雷击风险较高。因此,有效提高输电线路防雷性能评估水平与治理能力,对保证蒙东地区供电的稳定可靠是十分重要的。本文基于差异化防雷技术开展蒙东地区输电线路防雷综合治理研究。具体来说,选择雷害严重的典型线路采用差异化防雷技术开展逐基杆塔的微观化防雷风险评估,评估时综合考虑线路走廊雷电活动、地形地貌、线路结构和绝缘配置的差异性;根据风险评估结果,结合各种防雷措施特点和已有改造经验,选择线路避雷器作为改造措施,

Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.
