Abstract Urgency to save species from extinction has prompted increased investment in law enforcement in protected areas. To date, such law enforcement has largely focused on increasing costs and reducing opportunities for offending. However, these resource‐intensive approaches are not always effective and can contribute to conflict between people and ...

The Rhetoric of Disenchantment: Ghost Belief and Secular Critique in Early Twentieth‐Century China
Abstract This study presents the first large‐scale empirical analysis of how ghosts and spirits were debated during China's early twentieth‐century secular transformation. Using a novel dataset of over 2000 digitized texts—including newspapers, periodicals, and essays from 1890 to 1949—we combine close reading, AI‐assisted annotation, and statistical ...

蒙古野驴(Equus hemionus)昼间行为时间分配初探/Diurnal time budgets and activity rhythm of the Khulan[J]
于2007年和2010年采用焦点动物取样法研究了新疆卡拉麦里山有蹄类野生动物保护区蒙古野驴昼间行为时间分配和活动节律,共采集行为数据460 h,观察蒙古野驴2 760头次,将蒙古野驴昼间行为分为采食、移动、警戒、休息和“其他”5类.采用卡方检验分析不同季节各种行为时间分配,结果表明:季节因素对蒙古野驴行为时间分配存在极显著影响(X2=79.06,df=12,P<0.01).采用ANOVA分析同季节不同行为间差异,结果表明,春季:移动、警戒、“其他”两两间无显著差异(P>0.05),其余两两间差异显著(P<

The Future of AI in the GCC Post‐NPM Landscape: A Comparative Analysis of Kuwait and the UAE
ABSTRACT Comparative evidence of how two Gulf Cooperation Council (GCC) states translate artificial intelligence (AI) ambitions into post–New Public Management (post‐NPM) outcomes are scarce because most studies focus on Western democracies. To fill this gap, we examine constitutional, collective choice, and operational rules that shape AI uptake in ...
