Insights for conservation from the Ecological Knowledge Games project
Conservation Biology, EarlyView.Abstract Environmental conservation research requires robust methods for collecting large‐scale behavioral data and engaging diverse stakeholders in decision‐making processes. We (Y.P., A.B.D., and N.B.) created EcoKnowGames (Ecological Knowledge Games), a transdisciplinary project that develops knowledge games for conservation science and data ...

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.

Shuitu Baochi Xuebao, 2023 针对喀斯特地区景观格局驱动水源涵养功能演变机制的相关研究较少,而水源涵养功能是岩溶石漠化治理等生态修复工程生态效益的关键指标之一,具有重要的研究意义。以地处西南喀斯特中心的野纪河流域为研究对象,基于InVEST模型、偏最小二乘模型(PLSR)、景观生态学理论等,探究野纪河流域2005—2020年水源涵养功能的时空分异特征及其与景观格局的耦合关系。结果表明:(1)野纪河流域景观类型以旱地、草地和灌木林等为主,各类型之间相互转化较为频繁,总体特征表现为旱地、灌木林和草地之间的转化以及建设用地对其余地类的挤占。

International Journal of Applied Linguistics, EarlyView.ABSTRACT In English medium instruction (EMI), students face cognitive and emotional demands in second language (L2) communication, which may hamper their motivation and willingness to communicate (WTC). Adopting a mixed‐methods design, this study explores how growth mindsets affected student motivation (e.g., ideal L2 self and ideal disciplinary self ...

Shuitu Baochi Xuebao, 2021 土壤保持是黄土高原首要的生态系统服务功能，对于黄土高原地区生态经济可持续发展至关重要，开展该区域的土壤保持变化和影响因素研究十分必要。基于退耕还林还草背景，综合使用InVEST泥沙输移比模块、空间自相关、地理探测器等方法模型对2000—2017年子午岭地区土壤保持服务时空变化及影响因素进行了分析。结果表明：2000—2017年，子午岭地区大量耕地转为林地和草地，土壤保持服务有所增强，其中林地的单位面积土壤保持量最高；土壤保持随海拔呈先增后减趋势，随坡度的增大而增大，区内西坡和东坡处土壤保持量最高 ...

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Democratic Values in Citizen Participation: What Citizens Prioritize in Participation
Policy Studies Journal, EarlyView.ABSTRACT Citizen participation is often initiated to strengthen democracy. While participatory innovations are typically assessed through normative frameworks emphasizing democratic values, little is known about which of these values are prioritized by citizens.
