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

Longitudinal predictors of reading comprehension in French at first grade: Unpacking the oral comprehension component of the simple view     

《Learning and Instruction》2019

According to the simple view of reading (SVR), reading comprehension relies on “decoding” (pseudoword, word reading) and “oral comprehension” skills. Testing 556 French pupils, we aimed at unpacking these two components and tracking their longitudinal development in first grade. We have found that: (1) lower level language skills (vocabulary, syntax) and discourse skills (oral text comprehension) emerged as two dimensions of “oral comprehension”; (2) lower level language skills longitudinally predicted reading comprehension outcomes, above code-related skills; (3) decoding precursors (letter knowledge, naming speed and phonemic awareness) predicted reading comprehension directly, and indirectly, through decoding skills (pseudoword, word reading, text reading fluency); (4) Oral comprehension skills did not favour the development of decoding. Our results support the independency of the SVR components. However, we suggest that a more fine-grained conceptualisation of oral comprehension skills would help to better understand the individual and pedagogical factors influencing the early development of reading comprehension.  相似文献   

冰冻圈物理研究的新视野          下载免费PDF全文

任贾文 《中国科学院院刊》2020,35(4):450-455

冰是冰冻圈核心物质,但不同冰冻圈要素因冰的含量及其他物质组成有所不同,物理性质及各种物理过程存在明显差异。经过20世纪中后期对冰的物理性质的大量实验研究和冰冻圈主要要素物理特征的广泛调查,冰的物理性质和冰冻圈主要要素物理特征的基本概念得以明确。随着冰冻圈科学体系的建立和服务于社会经济发展的需要,冰冻圈物理研究在3个方面要着力发展:(1)提高冰和冰冻圈要素物理性质的定量刻画精度,为过程模拟、冰冻圈灾害防治和冰冻圈服务提供关键参数支持;(2)加强冰冻圈主要要素综合物理过程的模拟研究,特别是要开展实体和相似性模拟实验;(3)推进冰冻圈多模式及其与其他圈层模式的耦合研究。  相似文献   

Mobile users’ information privacy concerns and the role of app permission requests     

《International Journal of Information Management》2020

Recent privacy-related incidents of mobile services have shown that app stores and providers face the challenge of mobile users’ information privacy concerns, which can prevent users from installing mobile apps or induce them to uninstall an app. In this paper, we investigate the role of app permission requests and compare the impact on privacy concerns with other antecedents of information privacy concerns, i.e., prior privacy experience, computer anxiety, and perceived control. To test these effects empirically, we conducted an online survey with 775 participants. Results of our structural equation modeling show that prior privacy experience, computer anxiety, and perceived control have significant effects on privacy concerns. However, concerns for app permission requests have approximately twice as much predictive value than the other factors put together to explain mobile users’ overall information privacy concerns. We expect that our findings can provide a theoretical contribution for future mobile privacy research as well as practical implications for app stores and providers.  相似文献   

Social identification,exercise participation,and positive exercise experiences: Evidence from parkrun     

Mark Stevens  Tim Rees  Remco Polman 《Journal of sports sciences》2019,37(2):221-228

Growing evidence suggests that social identities may have profound implications for physical activity participation. Real-world examinations of this relationship have, however, been lacking, with research predominantly examining intentions and hypothetical scenarios. To address this shortcoming and further advance understanding in this area, the present study tested relationships between group identification, participation, two exercise-specific outcomes (exercise-specific satisfaction and group cohesion), and a broad health indicator (life satisfaction) among individuals recruited from parkrun. Participants (N = 289) completed questionnaires measuring all variables except participants’ parkrun participation, which was objectively assessed. Structural equation modeling demonstrated that group identification was significantly associated with greater participation, exercise-specific satisfaction, group cohesion, and life satisfaction. Findings provide real-world evidence of the health-related benefits associated with forming strong social identities in exercise settings.  相似文献
