基于偏微分方程的线性函数数据建模应用研究     

杨正校  蒋建武 《十堰职业技术学院学报》2011,24(5):104-108

通过线性函数数据建模,以偏微分方程理论为依据,使用Visual C#作为编程设计语言,通过串行通信口送入大量实验数据,并对海量数据进行实证分析,由此获取线性方程的数据建模方法,得到相应程序算法模型,在Visual C#环境下编写程序进行调试分析与测试,并详细介绍了该方法的具体设计过程,给出了关键程序代码,同时给出了利用该方法进行数据处理的一个实例。对于利用采样的海量数据获得线性函数的相关研究有一定的参考价值。  相似文献

Childhood trauma as a mediator between emotional intelligence and recidivism in male offenders     

《Child abuse & neglect》2019

BackgroundPrior researches have implicated a relationship of recidivism with childhood trauma (CT) and emotional intelligence (EI). However, the internal mechanism by which CT and EI influence the recidivism has not been examined.ObjectiveThis study aimed to map the road from CT and EI to recidivism in Chinese male offenders.Participants and settingThree thousand one hundred and eighty-one Chinese adult male offenders participated in this study and completed Childhood Trauma Questionnaire (CTQ) and Wong Law Emotional Intelligence Scale (WLEIS). Recidivism was quantified by the number of convictions according to official records.MethodsAfter controlling for age, education levels, family criminal history, and nature of offence, logistic regression sanalysis was performed to examine the effects of CT and EI on severity of recidivism. Structural Equation Modeling (SEM) was applied to explore the mediation model between CT, EI and recidivism.ResultsLogistic regression model shows a significant effect of CT (OR = 1.008, p < 0.01), rather than EI, on recidivism. SEM supported a full mediating effect of CT in the relationship between EI and severity of recidivism.ConclusionsOur findings suggest that EI has no direct effect on the recidivism, but exerts indirect influence on the recidivism through the mediating role of childhood trauma.  相似文献   

The role of cultural values in teacher and student self-efficacy: Evidence from 16 nations     

《Contemporary educational psychology》2019

Data from a large study (PISA, 2015) involving more than 132,000 children and 22,000 of their teachers, in 16 nations, were used to investigate how teachers convey self-efficacy to students when they teach and whether this is culturally grounded. Using a multilevel data analysis framework, we aimed to: (1) test a path linking teacher and student self-efficacy; (2) examine teaching practices as mediators of the links between teachers and student self-efficacy; (3) evaluate the moderating roles of cultural values on those links. Results indicated that teacher and student self-efficacy were linked indirectly through the use of teaching practices, more strongly through inquiry-based practices. We found cross-cultural differences on the associations between student-perceived teaching practices and student self-efficacy that were moderated by two country-level cultural values: individualism and uncertainty avoidance. This study highlights that, although academic self-efficacy is considered universal, we found cultural differences in its sources and manifestations.  相似文献
