农村留守儿童社会支持与孤独感的关系     

张连云 《中国特殊教育》2011,(5)

通过对264名留守儿童和213名非留守儿童进行问卷调查,探讨了不同情况下,社会支持对留守儿童孤独感的影响.结果表明:留守与非留守儿童在孤独感上没有显著差异;同学支持和母亲支持对非留守儿童的孤独感有显著负向影响,而同学支持、父亲支持和教师支持同时对留守儿童的孤独感具有显著负向影响;高自尊组留守儿童的孤独感显著低于低自尊组;只有同学支持对于低自尊组留守儿童的孤独感具有显著负向影响,而同学支持和教师支持同时对高自尊组留守儿童的孤独感也具有显著负向影响.  相似文献   

影响民航大学生数学学习成绩的因素     

曾艳  段春生  向丽 《内江师范学院学报》2011,26(4):79-81

以中国民航飞行学院飞行技术专业部分学生为研究样本,利用多种统计分析方法对影响大学生数学成绩的因素进行分析,考察教师的教学水平、学生的高考数学成绩等因素对大学数学成绩的影响.结果显示：教师的教学水平与学生的高考数学成绩对大学数学成绩的影响均显著,但高考数学成绩只能解释大学数学成绩12.6%的变异.结论：教师的教学水平与学生的学习能动性对大学数学成绩有良好的促进作用.  相似文献

高校扩招对我国居民收入分配差距的影响研究——基于1999—2018年省际面板数据的实证分析     

范晓婷  陈昕爽  张宁 《高校教育管理》2020,(3):73-82,103

本研究围绕高校扩招对居民收入分配差距的影响进行实证研究,选取1999—2018年我国31个省份(不含我国港、澳、台地区)的面板数据进行门槛回归估计。本研究发现,样本期间内高校扩招对于缩小收入分配差距具有显著作用,且表现出鲜明的门槛特征。高校扩招对收入分配差距的影响还存在经济门槛效应和技术门槛效应:经济发展水平越高,高校扩招缩小收入分配差距的作用越强;随着技术水平的提升,高校扩招缩小收入分配差距的作用先增强后减弱。据此,为更好地推动高等教育与社会经济发展,发挥高等教育人力资本促进居民收入分配公平的作用,我国可以实施因地制宜的分地区高校扩招政策;强化经济发达地区对经济欠发达地区的带动作用;加快培养高层次应用型人才以适应技术进步对高层次人才的需求。  相似文献

基于环境保护下的我国产业发展经济效益分析     

阎兆万 《现代企业教育》2007,(8):74-76

我国工业产业发展至今，环境保护已经成为影响各产业发展的重要因素，环境保护要求产业进行一定的投资，同时，这些投资也为产业的发展带来了巨大的价值，并且也促使了新型产业——环保产业的迅速发展，本文通过分析环境污染的经济损失，进而提出产业环境保护的价值链理论，分析产业环境保护的价值所在，并通过对我国近几年环境保护投资与三废综合利用产品产值进行回归分析，进一步说明我国工业产业环境保护的必要性。  相似文献   

Assessing and Controlling Acquiescent Responding When Acquiescence and Content Are Related: A Comprehensive Factor-Analytic Approach     

Pere Joan Ferrando  Fàbia Morales-Vives  Urbano Lorenzo-Seva 《Structural equation modeling》2016,23(5):713-725

This article proposes procedures for assessing and controlling acquiescence in personality scales when acquiescence is related to the content that the scale intends to measure. Our proposal is comprehensive in that it can be applied to different item response formats fitted with response models that can be parameterized as factor-analytic models. In the calibration stage, our proposal makes joint use of a balanced scale and a set of markers for acquiescence, and consists of 2 sequential procedures: a direct semirestricted solution, and a restricted solution with minimal identification constraints. In the scoring stage, we discuss how the information given by the acquiescence–content relation can be used to obtain Bayes expected a posteriori scores. The robustness of the direct procedure is assessed both analytically and by simulation. A free, user-friendly program that implements the procedures proposed is made available. Practical issues of use and interpretation are discussed and illustrated with an empirical application.  相似文献   

Domain Coloring and the Argument Principle     

Frank A. Farris 《PRIMUS》2017,27(8-9):827-844

Abstract

The domain-coloring algorithm allows us to visualize complex-valued functions on the plane in a single image—an alternative to before-and-after mapping diagrams. It helps us see when a function is analytic and aids in understanding contour integrals. The culmination of this article is a visual discovery and subsequent proof of the Argument Principle, which relates the count of poles and zeros of a meromorphic function inside a contour to the accumulated change in argument of the function around the contour. Throughout, I offer connections to standard learning goals of courses in complex variables.  相似文献

Antecedents to psychosocial environments in middle school classrooms in Taiwan     

Huang  Shwu-Yong L. 《Learning Environments Research》2003,6(2):119-135

This study investigated gender differences in students' perceptions of their psychosocial environment and related variables. Analyses of data collected from 644 middle school students reveal that there were significant differences in boys' and girls' perceptions, in favor of girls. Ten academic background variables were examined. Multiple regression results identified, in addition to gender, school membership, attendance, time spent doing homework, students' academic expectations, course grade, and course content as significant variables for all students, accounting for 31% of the variance in environment. There were gender-related disparities for the variables involved. While time spent doing homework, students' academic expectations, course grade, and course content had significant effects on both boys and girls' environments, school membership and time spent in watching TV had effects only on girls' perceptions. Educational implications of the findings are also discussed in the article. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献
