An Empirical Study on Foreign Language Majors’Needs for Ideological and Political Education Elements in Chinese Universities

The paper takes 2076 undergraduate students majoring in foreign languages from 15 Chinese universities as the research subjects to investigate their demand for ideological and political education elements in foreign language courses.The results show that:(1)Students have high needs for ideological and political education elements in foreign language courses;(2)There are differences in students’needs for ideological and political education elements across different dimensions.Students have higher demand for dimensions such as personal qualities,cultural literacy,moral cultivation,and patriotism,while their demand for dimensions related to constitutional law and political identity is relatively low.Therefore,foreign language majors in Chinese universities should optimize the supply of ideological and political education elements in their courses according to students’needs,and improve the effectiveness of moral education in these courses.

节水灌溉技术对农业灌溉效率的影响

采用节水灌溉技术提高农业灌溉效率对于保障国家粮食安全和促进农业可持续发展具有现实意义。运用超期望SBM模型分别测度粮食灌溉效率和蔬菜灌溉效率,并进一步运用Tobit模型实证分析节水灌溉技术对农业灌溉效率的提升作用。结果表明:粮食灌溉效率平均值为22.93%,蔬菜灌溉效率为45.80%;节水灌溉技术对农业灌溉效率具有显著的提升作用;年龄和地形对农业灌溉效率具有正向影响,灌溉设施对蔬菜灌溉效率正向影响。因此,提出加强农业生产指导,加强节水灌溉技术的宣传和推广,采用灵活多变、农户易于接受的培训形式等建议。
