也门胡塞武装的产生和发展不只是什叶派的栽德派在政治社会生活中边缘化时寻求复兴的直接结果,更折射出现代民族国家构建中的国家世俗化与政治伊斯兰运动、国家加强控制力与部落自治传统之间的结构性矛盾。伴随胡塞武装强势夺权,其对国家重构的影响力与日俱增,既改变了也门逊尼派主导政治权力的格局,还进一步削弱合法政府的控制力,在更大程度上主导着国家重构和地区安全形势。但是,也门国家政治重构将会持续一个较长时期,即便是胡塞武装与总统委员会作出实现也门内部长久和平的承诺后,也门政治和解依然任重而道远。

教师态度对超语实践发挥重要作用。本研究通过问卷调查我国高校外语教师对超语教学的态度及其可能的影响因素。结果显示,高校外语教师对超语教学整体持积极态度,非通用语专业教师的态度最为积极,英语专业教师的态度比公共英语教师积极,但后两组教师的态度并无显著性差异。教师的年龄、教龄与其对超语教学的态度不显著相关。研究结果有助于超语研究理论框架完善和我国高校外语教师发展。
