关于费马解的一个同余方程     

管训贵 《青岛职业技术学院学报》2011,24(4):47-48

设p为奇素数,a为整数,若ap-1≡(1mod p2),则a名为费马解。根据华罗庚给出的几个特殊的费马解,可以探求费马解的一般方法。利用初等方法及原根的性质研究同余方程xp-1≡(1modpl),l≥1的可解性,可以得到该同余方程的一切正整数解和费马解。  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
