Effect of heat treatment on the microstructure and mechanical properties of spray-formed 7055 aluminium alloy

7055 Al alloys samples were prepared by spray forming and hot-extrusion followed by two different aging treatment procedures. Their different distributions of GP zones, and nanoscale precipitates η′ (MgZn) and η (MgZn₂) are extensively investigated by transmission electron microscope (TEM). The mechanical properties, including tensile strength, Vickers hardness and elongation of both aged 7055 Al alloys, have also been measured and analysed. It is found that T6 and T76 aging treatment results in quite different microstructure and mechanical properties. The outstanding performance of the 7055 Al alloys after T6 aging treatment is attributed to nanoscale semi-coherent dispersion precipitates.     

竞争和合作对学龄前儿童分配模式的影响:心理理论和抑制控制的作用

研究考察在双方贡献不相等时,3~6岁儿童分配模式的发展趋势及其原因。98名儿童在竞争或合作情境下和玩偶进行钓鱼游戏,然后对6枚冰箱贴进行分配。结果发现5~6岁儿童比3~4岁儿童进行平均分配的比例更高,一级心理理论和抑制控制能力完全中介了年龄的效应。和竞争情境相比,合作情境促进儿童进行平均分配,同时情境调节了抑制控制对分配模式的影响。研究表明一级心理理论和抑制控制能力的发展能够解释学龄前儿童分配模式的变化。     

后现代主义视角下第二代认知科学的三个特征

具有浓厚哲学色彩的第二代认知科学,拥有一些后现代主义哲学的特征,作为对立面的经典认知,对比之下也展现出现代主义哲学的特征。从反基础主义、非理性主义和后人道主义三个方面,讨论二代认知的主张及其与经典认知的关系。二代认知理论中的矛盾之处,不仅是由于认知科学的发展惯性和理论发展的欠缺,也是理论本身的特殊性导致,对未来发展的思考更需要谨慎进行。     

关系流动性、拒绝敏感性与主观幸福感的关系

为了从社会生态学的视角探讨预测主观幸福感的相关因素、考察拒绝敏感性在其中的中介作用、揭示高关系流动的社会环境对心理健康可能的积极作用,以生活满意度和心理幸福感等为测量工具,对成人进行了研究。研究结果显示:关系流动性可显著正向预测主观幸福感; 拒绝敏感性在关系流动性与主观幸福感之间起中介作用。研究结果表明,高关系流动性能预测个体的低拒绝敏感性,进而预测更高的主观幸福感。     

The malleability of executive function in early childhood: Effects of schooling and targeted training

Executive function (EF), its importance for scholastic achievement and the question of whether or not EF is malleable, have become a topic of intense interest. Education or schooling is often seen as effective approaches to enhance EF due to the specific school‐related requirements as compared to kindergarten or pre‐school. However, no study to date has investigated whether targeted training focusing on those domains might be comparable with regular schooling in improving EF and fluid intelligence (Gf). The aim of the present study was to replicate and extend the previously demonstrated schooling effects on EF by using a school‐cutoff design, and to further investigate whether a theoretically motivated intervention targeting specific EF, i.e., working memory (WM) or inhibitory control (IC), could achieve comparable effects with schooling in both, WM and IC, as well as Gf. 91 6‐year‐old kindergarteners and first‐graders with similar chronological age participated the study. We compared the performance of a first‐grade schooling group with that of two kindergarten training groups as well as a business‐as‐usual kindergarten control group. Participants were assessed in WM, IC and Gf at baseline, immediately after the intervention (posttest), as well as 3 months after training completion (follow‐up). The results showed that the schooling group indeed outperformed the kindergarten groups at baseline in several cognitive tasks. Furthermore, both the WM and IC training showed pronounced gains in the trained tasks, as well as varying degrees of improvement in non‐trained outcome measures. Most importantly, both training groups achieved comparable performance with the schooling group, which was especially apparent in Gf at follow‐up. Our findings provide further evidence for the malleability of EF demonstrating that both, long‐term and short‐term interventions can facilitate the acquisition of those important skills, and as such, our work has important implications for educational practice.     

Retraction and Research Integrity Education in China

This article draws the attention of research managers and policy makers to the issue that to become a science power curtailing misconduct is the daunting challenge that emerging countries simply cannot ignore. Systematic and orchestrated efforts are needed to foster and institutionalize research integrity education among all stakeholders.

     

The resilience status of Chinese left-behind children in rural areas: a meta-analysis

The resilience has become the main trend of the left-behind children's (LBC) mental health research. To evaluate the resilience status of Chinese LBC in rural areas, a meta-analysis was performed. Relevant studies were identified using electronic databases from 1990 to 2017. Pooled weighted mean difference (WMD) and 95% confidence interval (95% CI) were calculated with fixed and random effects models. A total of 14 cross-sectional studies with 9777 individuals were included in this meta-analysis. The results showed there was significant difference in the aspects of family support and RSCA (Resilience Scale for Chinese Adolescents) total score between LBC and non-left-behind children (NLBC). After stratification subgroup, significant difference in RSCA total score was also found in subgroup with sample size ≥700 and target population (LBC) between LBC and NLBC. In addition, there was no significant difference in resilience of male and female among LBC (P >0.05). We also found RSCA total score of LBC whose one parents migratingwere higher than both parents (P <0.05) and the time of parental migration (≤2 years) were higher than others (>2 years). In conclusion, more attention should be paid to the LBC, especially both parents migrating or parental migration (>2 years).     

领导幽默风格对团队内部学习的影响

采用幽默风格量表（HSQ）、领导成员交换量表（LMX-16）和团队内部学习问卷,以325名事业单位员工为调查对象,研究了领导幽默风格和团队内部学习、领导成员交换的关系。结果发现：（1）亲和型领导幽默和自强型领导幽默正向影响团队内部学习,嘲讽型领导幽默和自贬型领导幽默负向影响团队内部学习。（2）亲和型领导幽默和嘲讽型领导幽默对团队内部学习的影响完全通过领导成员交换起作用,自强型领导幽默对团队内部学习的影响部分通过领导成员交换起作用。（3）自强型领导幽默与嘲讽型领导幽默通过领导成员交换对团队内部学习的影响都大于亲和型领导幽默;自强型领导幽默对团队内部学习的直接效应大于自贬型领导幽默。     

Gender‐specific factors associated with the suicidal ideation of children in Taiwan: A large‐scale cross‐sectional study

We examined the relationship between suicidal ideation (SI) and the depressed mood, life stress and parenting styles in children. A large‐scale survey was conducted including 5328 children from 65 elementary schools in Taiwan. SI was measured by asking children if any suicidal thoughts had occurred in the previous month. A series of regression models was analysed separately for male and female students. Compared with boys, girls demonstrated a higher proportion of SI. Among boys, SI was significantly associated with a high level of perceived environmental stress (adjusted odds ratio [aOR] = 2.61), a high degree of depressed mood (aOR = 2.39), authoritative (aOR = 1.72) and authoritarian (aOR = 2.53) parenting styles and two or more life‐stress events (aOR = 1.45). A high level of perceived environmental stress (aOR = 2.09), a high degree of depressed mood (aOR = 2.89) and an authoritarian parenting style (aOR = 1.76) were significantly associated with the SI in girls. Gender‐specific interventions aimed at preventing SI must enhance support systems at school and at home, particularly for students who suffer from a high degree of stress and depressed mood, and are subjected to an authoritarian parenting style.
