Promoting the development of resilient academic functioning in maltreated children

This study examined (a) the extent of heterogeneity in the patterns of developmental trajectories of language development and academic functioning in children who have experienced maltreatment, (b) how maltreatment type (i.e., neglect or physical abuse) and timing of abuse explained variation in developmental trajectories, and (c) the extent to which individual protective factors (i.e., preschool attendance, prosocial skills), relationship protective factors (i.e., parental warmth, absence of past-year depressive episode, cognitive/verbal responsiveness) and community protective factors (i.e., neighborhood safety) promoted the development of resilient language/academic functioning trajectories. Longitudinal data analyses were conducted using cohort sequential Growth Mixture Model (CS-GMM) with a United States national representative sample of children reported to Child Protective Services (n = 1,776). Five distinct developmental trajectories from birth to age 10 were identified including two resilient groups. Children who were neglected during infancy/toddlerhood or physically abused during preschool age were more likely to be in the poorer language/academic functioning groups (decreasing/recovery/decreasing and high decreasing) than the resilient high stable group. Child prosocial skills, caregiver warmth, and caregiver cognitive stimulation significantly predicted membership in the two resilient academic functioning groups (low increasing and high stable), after controlling for demographics and child physical abuse and neglect. Results suggest that it is possible for a maltreated child to successfully achieve competent academic functioning, despite the early adversity, and identifies three possible avenues of intervention points. This study also makes a significant contribution to the field of child development research through the novel use of CS-GMM, which has implications for future longitudinal data collection methodology.     

A virtual safe zone: Teachers supporting teenage student resilience through social media in times of war

We examine how teacher-student communication through social network technologies may support student resilience during an ongoing war (i.e., the 2014 Israel-Gaza war). Based on student responses from open-ended surveys (N = 68), five content categories of emotional support were identified: caring, reassuring, emotion sharing, belonging, and distracting. The mere existence of continuous online contact with teachers also contributed to resilience perceptions. Interviews with 11 secondary school teachers revealed three main purposes for this communication: (a) delivering emotional support to students, (b) monitoring their distress; and (c) maintaining civilized norms of discourse. Practical implications and theoretical contributions are discussed.

‘They don't realise how hard it is’. Investigating the lived experiences of higher education students with parental responsibilities during the Covid-19 pandemic

Anecdotal reports of student parents’ challenges during the Covid-19 pandemic prompted this explorative study; investigating the lived experiences of UK student parents and the provision of Higher Education support. Data was derived from 91 online surveys, 20 follow-up interviews, and analysis of 100 university websites. This occurred during the pandemic lockdowns whenthe stresses, challenges and opportunities of balancing their simultaneous roles of parent and student were intensified due to school closures. The Double ABC-X model provided a framework for examining participant's lived experiences, and the role that Higher Education institutions could play in effecting positive coping and adaptation. Findings indicate that universities need to implement strategies to enhance support for this sector, including greater awareness of the vulnerabilities and challenges involved, more flexibility and adaptability in the university ethos, formal and informal policies and structures to provide more effective support and advice for juggling these simultaneous demands.     

Education of unaccompanied refugee minors in high-income countries: Risk and resilience factors

Record numbers of unaccompanied refugee minors continue to arrive in high-income countries seeking asylum and protection. Despite receiving educational support, unaccompanied refugee minors continue to be vulnerable to negative educational experiences and outcomes. The review investigates what resilience factors enable unaccompanied refugee minors in high-income countries to have positive educational experiences and outcomes. It aims to inform the literature on risk and resilience factors and the development of future interventions. Eighteen articles met the eligibility criteria for the review. Twenty-six factors were identified as risk and resilience factors related to five socio-ecological levels: child, microsystem, mesosystem, exosystem, and macrosystem. The findings revealed significant heterogeneity. Microsystemic and mesosystemic factors were found to play the most important role in educational resilience. Meanwhile, young mothers, minors who experienced immigration detention, and minors whose immigration statuses are unknown or pending are sub-groups of unaccompanied refugee minors who are particularly vulnerable to risk. Findings are discussed with implications for future research, policy, and practice. Future studies need to elaborate whether their findings are particular to the condition of being unaccompanied or being refugee.     

我国地球科学发展的若干思考与建议

地球科学是以地球各圈层相互作用及其资源与环境效应为研究对象，多学科交叉融合的一门科学。地球科学既研究过去，阐述地球演化历史，又面向未来，为人类可持续发展提供解决方案，是一门既能拓展人类知识前沿又能服务于人类社会经济发展的综合性、系统性的科学。文章在梳理国际地球科学发展趋势和总结我国地球科学发展现状与科技资助情况的基础上，提出我国地球科学发展应从系统科学和国家需求的视角部署未来发展方向和研究计划。从地球系统整体出发，关注地球系统各圈层、各要素之间的相互作用及其对人类社会经济发展的影响。以“四个面向”引领地球科学领域研究的发展方向，开展有组织的重大科学研究，完善科技资助与评价机制，使研究成果更好地服务于国家重大战略需求。     

A novel framework for deep knowledge tracing via gating-controlled forgetting and learning mechanisms

In this paper, we propose a framework called Gating-controlled Forgetting and Learning mechanisms for Deep Knowledge Tracing (GFLDKT for short). In GFLDKT, two gating-controlled mechanisms are designed to model explicitly forgetting and learning behaviors in students’ learning process. With the designed gating-controlled mechanisms, both the interaction records and students’ different backgrounds are combined effectively for tracing the dynamic changes of students’ mastery of knowledge concepts. Results from extensive experiments demonstrate that the proposed framework outperforms the state-of-the-art models on the KT task. In addition, the ablation study shows that designed forgetting and learning mechanisms contribute clearly to the performance improvement of GFLDKT.     

我国体育场地统计机制优化研究

为优化我国体育场地统计机制，科学建设未来体育场地设施。运用文献资料法、实地调研法等，回溯我国6次场地普查发展历程，结合2019年第4次全国经济普查暨全国体育场地统计调查情况进行分析。发现，当前我国体育场地统计工作主要面临部门配合脱节、经费保障不到位、调查员专业素质不足、部分被调查者不配合、测量与统计方法不科学、体育场地名录信息不全且公开内容有限等问题。提出，要构建政府主导、多部门协作的工作体系；建立投入保障机制与工资激励机制；注重业务培训，提升调查员专业素质；加大宣传力度，调动社会力量参与；优化指标体系，减轻统计工作负担；强化信息管控，保证数据质量；健全体育场地名录库，完善数据披露制度，最大化发挥数据价值。
